Virtually all central heating and air conditioning systems are controlled by a low-voltage thermostat that tells the system when to turn on and shuts it off when the house temperature has reached the desired level. These thermostats are called low voltage because they run off a transformer that reduces line voltage from 120 volts to a level somewhere between 12 and 24 volts, depending on the brand of furnace you own.
When an HVAC (Heating, Ventilation, Air Conditioning) system doesn’t work quite as it should, very often it can be traced to a problem with the thermostat. Because these are easier to fix, the thermostat is the first place to look for problems. If the trouble is not there, then the problem may be in the furnace itself.
There are three HVAC symptoms that can often be traced to problems with the thermostat:
- The system produces no heat or cooled air
- The furnace does not set the temperature to the desired level—it is either too cold or too warm
- The system cycles (turns on and off) too frequently
If the HVAC system fails to turn on at all, there are a number of thermostat problems that should be considered before assuming the furnace or AC unit is to blame. In many cases, this symptom is the result of no electrical current reaching the thermostat.
- Circuit breaker tripped or fuse is blown
- Thermostat components are dirty
- Loose wires or open connection in the thermostat
- Bad battery on digital electronic thermostats
- Reset circuit breaker or replace burned out fuse.
- Remove thermostat cover and gently clean components, especially the bimetallic coil and the switch contact surfaces. Set the thermostat to its lowest setting and clean the bimetallic coil with a soft brush or compressed air. Set the thermostat to its highest setting and clean the coil again. Then, reset the thermostat to its desired setting.
- Tighten any loose screw terminals. If a wire is loose from its terminal, place the wire back on the terminal clamp and tighten the screw.
- Check for loose connections or disconnected wires on a low-voltage transformer, which is usually mounted on the furnace.
- On electronic thermostat models, check to see if the display is working, indicating power. If it is not working, replace the batteries in the thermostat.
Sometimes the furnace/AC system will run, but will fail to set the temperature to the level you’ve chosen.
- Thermostat is mounted crooked
- The heat anticipator is not set correctly
- Remove the cover of the thermostat and loosen the screws that hold the unit to the wall. Level the thermostat, then retighten the screws and replace the cover.
If a furnace/ AC system turns off and on again frequently—a symptom known as short-cycling—it is usually because the electrical connections within the thermostat are not making clean, consistent contact. Be aware, though, that when outside temperatures are radically higher or lower than the desired indoor temperatures, it is normal for the HVAC system to cycle fairly frequently. On a bitterly cold winter’s day, for example, your furnace may start and stop quite often.
- Dirty thermostat components
- Heat anticipator not set correctly
- Remove the thermostat cover and gently clean components ,especially the bimetallic coil and the switch contact surfaces.
- Adjust the heat anticipator.

Gaming, once considered a niche hobby, has transformed into a global phenomenon, captivating millions of players worldwide. From the early days of pixelated graphics to the immersive worlds of virtual reality, the gaming industry has undergone a remarkable evolution, driven by technological advancements and changing consumer demands. In this article, we’ll explore the journey of gaming, tracing its roots, milestones, and the profound impact it has had on culture and society.
The Birth of Gaming:
The history of gaming dates back to the 1950s and 60s when computer scientists and researchers began experimenting with simple electronic games. These early games, such as “Spacewar!” and “Pong,” laid the foundation for what would become a multibillion-dollar industry. However, it wasn’t until the 1980s that gaming truly took off with the introduction of home gaming consoles like the Atari 2600 and the Nintendo Entertainment System (NES). These consoles brought gaming into the living rooms of millions of households, sparking a cultural phenomenon.
The Rise of 3D Graphics and Consoles Wars:
The 1990s witnessed a significant leap forward in gaming technology with the advent of 3D graphics and CD-ROM technology. Games like “Super Mario 64” and “Final Fantasy VII” showcased the power of 3D rendering, immersing players in rich, expansive worlds like never Rtp Slot before. Concurrently, the era saw fierce competition between gaming console manufacturers, with Sega, Nintendo, and Sony vying for dominance in what became known as the “console wars.” This era not only pushed the boundaries of gaming technology but also fueled a sense of tribalism among players, each passionately advocating for their preferred console.
The Emergence of Online Gaming and Esports:
As the internet became more accessible in the late 1990s and early 2000s, online gaming emerged as a game-changer. Titles like “World of Warcraft” and “Counter-Strike” brought players together in vast virtual worlds, transcending geographical boundaries and fostering online communities. Concurrently, competitive gaming, or esports, began to gain traction, with tournaments drawing massive audiences and lucrative sponsorships. Today, esports is a billion-dollar industry, with professional players competing in stadiums and arenas around the world.
The Era of Mobile Gaming and Casual Gamers:
The rise of smartphones in the late 2000s transformed gaming yet again, bringing it to the fingertips of billions of people globally. Mobile games like “Angry Birds” and “Candy Crush Saga” introduced gaming to a new demographic of casual players, many of whom had never considered themselves gamers before. This accessibility and convenience fueled the growth of the mobile gaming market, which now represents a significant portion of the gaming industry’s revenue.
The Dawn of Virtual Reality and Augmented Reality:
In recent years, advancements in virtual reality (VR) and augmented reality (AR) have pushed the boundaries of immersive gaming experiences. VR headsets like the Oculus Rift and PlayStation VR transport players to virtual worlds where they can interact with environments in unprecedented ways. Likewise, AR games like “Pokémon Go” blend the virtual and physical worlds, allowing players to hunt for digital creatures in real-world locations. As VR and AR technology continues to improve and become more accessible, the potential for transformative gaming experiences is limitless.
From humble beginnings to cutting-edge virtual realities, the evolution of gaming is a testament to human ingenuity and creativity. What began as simple electronic diversions has blossomed into a diverse and vibrant industry that spans genres, platforms, and demographics. As technology continues to advance and society evolves, one thing remains certain: gaming will continue to captivate and inspire generations to come.

4 4 Battery Application Handbook 2nd Ed. INTRODUCTION T his brief guide covers both the Cyclon and Genesis rechargeable sealed-lead battery product lines and is intended to serve as an introduction to various aspects of pure lead-tin battery applications. It is hoped that these notes will be useful to those looking for general information on the proper use of these two power sources, manufactured exclusively by Hawker Energy Products Inc., in Warrensburg, Missouri, USA.
5 Battery Application Handbook 2nd Ed. 5 F ollowing is a list of key features applicable to both Cyclon and Genesis batteries: Maintenance-free design Cyclon and Genesis cell designs incorporate sealed, starved electrolyte chemistry with permanent, hardened termination on all product models. PRODUCT FEATURES Orientation flexibility These batteries may be installed and operated in any orientation, allowing greater flexibility in product design and use. Negligible gassing Gassing under normal charging conditions is negligible, making Cyclon and Genesis safe for installation in human environments, such as offices and hospitals. Safety Both product lines are Underwriters Laboratory (UL) recognized, as a component per UL Standard 924. Wide operating temperature Both Genesis and Cyclon offer very broad operating temperature ranges, from -65 C to +65 C for Cyclon, and from -40 C to +60 C for Genesis. (Please refer to product specification sheets for the capability of each product type.) Long Life Pure lead-tin grid, better than 99.9% recharge recombination efficiency, higher vent design pressures, superior plate-to-cell/cell-compression integrity, and stronger case materials all contribute to the longer life, lasting durability, and extreme ruggedness of our batteries, making both Cyclon and Genesis the preferred choice for a variety of high reliability and high performance applications. Superior high rate performance Due to their very low internal resistance, both Cyclon and Genesis are capa-
6 6 Battery Application Handbook 2nd Ed. ble of extremely high rates of pulse and continuous discharge, making it possible to use a smaller battery package, than if an equivalent conventional lead battery had been used. Superior low temperature performance At -40 C, Cyclon cells are able to deliver 50% of its C/10 room temperature (25 C) capacity, which is significantly higher than the performance of conventional cells. Similarly, at -20 C, Genesis batteries will deliver 65% of its 15-minute room temperature capacity, again considerably higher than traditional sealed-lead batteries. Superior fast charging in cyclic applications Extremely low internal resistance, coupled with no current limit requirements under constant voltage charging, facilitates very fast recharges in cyclic applications. Flame retardant V0 packaging Cyclon single cells and the Genesis SP and EP series are both available in V0 rated case and cover materials. Flash arrestors are standard features in the 120W and 190W Genesis SP series batteries. On Cyclon single cells, the seal between the V0 rated plastic top and the metal can provides a tortuous path for an external flame attempting to move back into the cell through the resealable vent. This design has proven its merit through 20 years of service history and has been accepted by the telecommunications industry to be functionally equivalent to a flash arrestor. Dry cell classification Hawker Energy Products Inc. s batteries are dry by design and have been tested and determined to be in compliance with section (d) of the United States Department of Transportation (USDOT) regulation. They are excepted from all other shipping requirements of
7 Battery Application Handbook 2nd Ed CFR, subchapter , and as of September , all shipments are classified as unregulated nonspillable wet electric storage batteries. All batteries and shipping containers are marked NONSPILLABLE or NONSPILLABLE BATTERY. THE GENESIS EP AND VP MODELS
8 8 Battery Application Handbook 2nd Ed. APPLICATIONS oth Cyclon and Genesis cells and batteries find B homes in a broad range of applications, ranging from standby to highly cyclic. Examples of standby applications are backup power for computers, UPS systems and telecommunications, while typical cyclic applications include electric vehicles, motive, cordless electric lawn mowers and portable instrumentation. A commonly asked question is what delineates a standby application from a cyclic application? Although there is no clear demarcation between the two types of applications, the answer to this question lies in the response to another question how much time is available to fully recharge the battery? If at least two weeks (336 hours) are available to accomplish the recharge, then the application is of a standby or emergency nature. It follows then that any recharge time less than 336 hours constitutes a cyclic application.
9 Battery Application Handbook 2nd Ed. 9 he key to obtaining maximum life from a sealed-lead T battery is optimum charging. Based on the specific characteristics of an application, the recommended charging parameters would vary. While there are several effective methods to recharge a sealed-lead battery, the following statement must be satisfied, regardless of the charge regime selected: CHARGING For every ampere-hour discharged from a battery, between 1.05 and 1.10 ampere-hours MUST be returned to ensure a complete & adequate recharge. Broadly speaking, a battery may be recharged using either a constant voltage (CV) charger, or constant current (CC) charger, or a modification of either or both of these. The exact regime chosen generally depends upon the time and economic constraints imposed by the system. Constant voltage charging, where a single voltage level is applied across the battery terminals, is the most suitable method to recharge a sealed-lead battery. Both Cyclon and Genesis cells and batteries are unique in that neither requires a current limit when using a CV charger. Depending on the CV charger's current limit, it is possible to recharge these batteries from a 100% discharged condition to better than 95% state of charge in less than one hour, using only the float charge voltage. Constant Voltage Charging At an ambient temperature of 25 C and a purely float application, the recommended charge voltage is 2.27 volts per cell
10 10 Battery Application Handbook 2nd Ed. (vpc) for Genesis. Cyclon D (2.5Ah) and X (5Ah) single cells, and D, X, and E (8Ah) monoblocs, may be float charged at 2.27 to 2.35 vpc at 25 C provided that the AVERAGE time on charge between two successive discharges is thirty (30) days. The MINIMUM time between two such successive discharges must be no less than fourteen (14) days. If these minimum recharge times are not practical, then the application must be considered to be cyclic, rather than float, and cyclic charge voltages MUST be used. The batteries may be left on charge indefinitely at these float voltages, since the batteries themselves will determine the current drawn based on their requirements. When CV charging is used in cyclic applications, the voltage level is higher because of the reduced time available for the recharge. In this case, the recommended voltage is 2.45 vpc with a minimum current limit of 1C 1. Such a high voltage should be applied for a minimum of 16 hours and no more than 24 to 48 hours 2. After that time, the charger should either be shut off or the voltage lowered to the appropriate float value. Constant Current Charging While CC charging for sealed-lead cells is not as popular as CV charging, it is widely used in cyclic applications where a recharge must be accomplished in a relatively short time period. Although a CC charge enables one to complete a full recharge quicker, greater care must be exercised to prevent any damaging overcharge. The potential for such an overcharge is greater in a CC charge mode, because a high current is imposed on the battery, regardless of its state of charge. This is in contrast to a CV charge regime, in which the battery determines the current it draws. 1 The C rate is the charge or discharge current in amperes that is numerically equal to the rated capacity of a cell in amperes. For a 5Ah cell, the C rate would be 5A; the C/2 rate would be 2.5A. 2 These charge times assume a 100% depth of discharge (DOD)
11 Battery Application Handbook 2nd Ed. 11 One other point needs to be kept in mind, should one opt for the CC method. Depending on the type and size of the battery, the charge current should be limited to a value ranging from a high of C/3 to a low of C/5 amperes. There are several other methods, such as two-step CV and two-step CC, to recharge a sealed-lead battery, all of which are variations of the two broad methods outlined above. A fairly widely used method in cyclic applications is a combination CC and CV charge. The regime begins with a CC charge until a certain battery terminal voltage is reached, at which point the charger switches to a CV mode to complete the charge. Other Charging Methods Special charge regimes have been developed that enable our batteries to be fully charged, from a 100% DOD in about six (6) hours. (See our EV Handbook for more details on this regime.) Regardless of the actual method chosen to recharge sealedlead batteries, one must not lose sight of the fact that proper and adequate charging is the single most important factor in obtaining optimum life from a battery, be it float or cyclic. If either Cyclon or Genesis batteries are to be charged using a multistep charging scheme, ALWAYS solicit the advice of Hawker Energy Products Inc. Heat is a killer of sealed-lead batteries. A rule of thumb is that for every 7 C to 10 C rise in battery ambient temperature above 25 C, the expected life of the battery is reduced by 50%. Thus, a battery rated at 8 years on float at 25 C is only a four (4) year battery at an ambient temperature of 32 C to 35 C. Ideally, then, the battery must be thermally isolated from any source of heat, such as a power transformer. Temperature Compensation
12 12 Battery Application Handbook 2nd Ed. This reduction in life is caused by heightened electrochemical activity within the cell as the temperature rises. To partially offset this effect, the charging voltage must be compensated using a negative coefficient. In other words, as the temperature rises, the charge voltage must be lowered. Conversely, as the ambient temperature decreases, the charge voltage must be increased. Note that temperature sensing must be done at the battery itself. Please consult the factory or the specification sheets for the appropriate temperature compensation (TC) coefficient. It is important to understand that while TC is recommended for ambient temperatures significantly above or below 25 C, its implementation does not mean that the effect of a high or low temperature is fully neutralized. Also, rapid fluctuations in ambient temperature do not call for a TC circuit simply because adequate time must be allowed for the battery to reach thermal equilibrium with its environment. In such a case, the charge voltage should be set for an average temperature.
13 Battery Application Handbook 2nd Ed. 13 he discharge curves at different rates for Cyclon and T Genesis batteries to specific end of discharge voltages (EODV) may be found in the appropriate specification sheets. The capacity in ampere-hours (Ah) at any rate may be found by multiplying the discharge rate (measured in amperes) by the time of discharge (measured in hours). DISCHARGE For example, if a battery delivers 2A for 5 hours down to an EODV of 1.70 vpc, then that battery is a 10Ah battery at the 5 hour rate of discharge. All Hawker Energy Products Inc. batteries are rated at the 10 hour rate of discharge. When considering the overall question of discharge, two factors must be kept in mind the EODV must be kept high enough to ensure that the battery is not overdischarged for a given application, and the correction factor if the battery is discharged at a temperature significantly higher or lower than 25 C. Although both Cyclon and Genesis products have excellent overdischarge recovery characteristics, it is recommended that the EODV numbers given in Table I be implemented. EODV As A Function Of Rate Of Discharge TABLE I Discharge rate Minimum EODV in Amperes per cell 0.05C (C/20) 1.75V 0.10C (C/10) 1.70V 0.20C (C/5) 1.67V 0.40C (C/2.5) 1.65V 1.00C 1.60V 2.00C 1.55V >5.00C 1.50V
14 14 Battery Application Handbook 2nd Ed. Discharge Rate Correction Factor Since the sealed-lead battery is temperature sensitive, it is good practice to apply a correction factor when the temperature of discharge is other than 25 C. Please consult Hawker Energy Products Inc. for an appropriate correction factor. These factors, suggested by the Institute of Electrical and Electronic Engineers (IEEE), are based on both the temperature of discharge, as well as the duration. THE CYCLON MONOBLOC
15 Battery Application Handbook 2nd Ed. 15 hen a battery is kept in storage, i.e. on open W circuit, the ambient temperature should be controlled to prolong storage time and maintain maximum capacity over time. To get the best storage results, batteries should be charged prior to storage, stored at room temperature or below, and charged prior to being put back in service. STORAGE The OCV of each battery must be monitored on an individual basis. If the OCV measures 1.93 vpc, it has zero effective capacity and should be boost charged immediately. Even if the OCV reads higher than 2.00 vpc at the end of 24 months storage, the battery should be recharged. Thus, to maintain maximum reliability, batteries should be boost charged once every 24 months, or when the OCV reads 2.00 vpc, whichever occurs earlier. If the OCV is allowed to drop between 1.93 and 1.80 vpc, some permanent damage may occur to the battery. However, if it drops to less than 1.80 vpc, the battery will most likely be unchargeable by conventional methods. Therefore, under no circumstances must the OCV be allowed to drop below 1.80 vpc. Just as high temperature accelerates the aging of a battery, so does it accelerate the self-discharge rate of a battery. Thus, when the storage temperature exceeds 25 C, one must monitor the OCV of the batteries more frequently. Conversely, at temperatures less than 25 C, the self-discharge rate reduces, and the time intervals between OCV checks can be correspondingly increased.
16 16 Battery Application Handbook 2nd Ed. SERVICE LIFE Float (Standby) Life he service life of a rechargeable battery may be T defined either in terms of float life or cycle life. While float life is specified in terms of years it takes to reach end of life 3 at an ambient temperature of 25 C, cycle life is indicated in terms of the number of cycles 4 one can get to a specified depth of discharge (DOD). The float life of a battery is measured in calendar time (years) when essentially all of its life is spent in an overcharge condition. The battery ambient temperature, typically room temperature or 25 C, is also specified. Both Genesis and Cyclon cells and batteries have a designed float life of eight (8) years at 25 C. The float life of a sealed-lead cell is greatly affected by both ambient temperature and charge voltage. As a rule of thumb, every 7 C to 10 C rise in temperature above 25 C reduces the expected float life by 50%. Similarly, every 100mV per cell above the recommended charge voltage also cuts battery float life by 50%. These dramatic numbers highlight the importance of temperature-compensated CV float chargers. Cycle Life The cycle life of a battery is defined as the number of cycles a battery delivers before its capacity falls below the acceptable level, usually defined as 80% of rated capacity. The cycle life of a battery is directly related to the depth of discharge, as well as the rate of discharge. (For specific cycle life numbers for Cyclon and Genesis batteries, please refer to the relevant specification sheets.) Adequate charging is critical in cyclic applications. In our experience, undercharging is a leading cause of premature bat- 3 A battery has reached "end of life" when it fails to deliver a minimum of 80% of its rated capacity. 4 A battery has "completed a cycle" if it starts out from a full state of charge, completes a discharge and is then fully recharged.
17 Battery Application Handbook 2nd Ed. 17 tery failure in cyclic applications. Although overcharge and undercharge are both detrimental to the life of a battery, the impact of undercharging is more acute than that of overcharging. Hence, for cyclic applications, where the calendar life is relatively short, it is very important to ensure that the batteries are not undercharged. For Cyclon and Genesis product lines, the recommended cyclic charge voltage is about 2.45 vpc. If the current limit is a minimum of 1C, they may be fully recharged from a 100% DOD in 16 hours. If the DOD is less than 100%, the recharge time would be less. THE CYCLON SINGLE CELL
18 18 Battery Application Handbook 2nd Ed. APPLICATION TIPS T o get the most out of your batteries, below are some helpful suggestions: Be aware of temperature effects, whether steady-state or excursions. Higher temperatures shorten life, and colder temperatures reduce performance. Recharge methods must keep pace with the expected duty cycle. Undercharging, inadequate charger control and shorter-than-required charge time allowances will all result in acute loss of performance. Depth of discharge will influence product life and duty cycle times. Standby charging must minimize and regulate overcharge currents to provide maximum life.
19 Battery Application Handbook 2nd Ed. 19 W hen designing your product, asking yourself the following questions may help better define your power needs: Program intent What power needs does my product have? PRODUCT DESIGN QUESTIONS Customers In what type of environments will my customers use my product, and how will those different environments affect the battery's performance? Battery features What sort of power needs are my customers looking for? Charging How will my customers charge the battery to ensure maximum performance? What charging requirements will my product need? Battery selection What size battery (or battery configuration) do I need to power my product? How large does my battery cavity need to be? User requirements How can I best educate my customers to ensure that they will receive the intended service performance and product life from the battery in my product?
20 20 Battery Application Handbook 2nd Ed. PRECAUTIONS T he following tips have been provided to help you get the maximum benefit from your batteries, whether in float or cyclic applications: Since high temperature has such a huge impact on a battery's life, every effort must be made to isolate the battery from any heat-producing source such as power transformers. For float applications, temperature compensated chargers are strongly recommended. A low voltage disconnect (LVDC) should be included in the load circuit to isolate the battery when its terminal voltage drops to a predetermined level (see Table I, page 13). A battery must not be charged in a sealed container. Any hydrogen gas evolved during the charging process must be allowed to escape. A minimum air space of 0.15" (3.8mm) must be provided on each side of the battery. When installing batteries, insulating gloves must be worn. All metallic items such as watches, bracelets and other personal jewelry should be removed. Only insulated tools should be used when working on batteries to prevent accidental short circuits. Batteries are capable of generating extremely high instantaneous currents if a short circuiting path between the positive and negative terminals is provided. Such large currents will cause serious personal injury. DO NOT SHORT CIRCUIT BATTERIES!!
21 Battery Application Handbook 2nd Ed. 21 Do not mix batteries of different capacity, age or make in the same system. Always use a charging regime appropriate for the application. If a split rate (multistep) charger is used, the charger must have multiple sense/switch points to assure proper function in all duty cycle scenarios. Batteries must always be stored in a cool, dry area and should be fully charged prior to being placed in storage. Sealed-lead rechargeable batteries, such as Cyclon and Genesis, are recyclable. It is recommended that exhausted Cyclon and Genesis batteries be recycled in compliance with local recycling legislation.

The United States Department of Energy (DOE) has been at the forefront of the solid-state lighting revolution. Among its various activities, DOE has supported studies forecasting the market penetration of light-emitting diodes (LEDs) in general illumination applications since 2002. These forecasts provide a comprehensive overview of the expected path of LED adoption within the U.S. and estimate the energy savings offered by LED products out to year 2035.
In general, LEDs have surpassed many conventional lighting technologies in terms of energy efficiency, lifetime, versatility, and color quality, and, due to their increasing cost competitiveness, LEDs are increasingly more successful in competing in a variety of lighting applications.
The DOE’s Solid-State Lighting Program Goal for LED efficacy is to achieve a 75% reduction in energy consumption by 2035. Looking at the cumulative effect of this reduction in energy consumption from 2015 to 2035, it is possible to generate a total cumulative energy savings of 62 quads through LED lighting which is equivalent to nearly $630 billion in avoided energy costs.
Based on the September 2016 Energy Savings Forecast of Solid-State Lighting in General Illumination Applications report commissioned by the DOE, the forecast for U.S. LED installed penetration rate is as follows:
The DOE lighting market model assumes the market adoption of LED lighting technology is driven primarily by projected improvements in LED product efficacy and price, as well as established technology diffusion rates. At the end of the analysis period, LEDs are anticipated to hold the majority of lighting installations in each of the submarkets examined, comprising 86% of all unit installations by 2035.
The projected increase in migration to LED lights is also influenced by the Energy Independence and Security Act of 2007. Originally named the Clean Energy Act of 2007, this congressional act focuses on the energy policy of the United States. The Act requires improved efficiency of roughly 25 percent for light bulbs, phased in from 2012 through 2014, and effectively bans the manufacturing and importing of most incandescent light bulbs.
Prior DOE analysis indicates that from 2012 to 2014, LED installations increased in all applications, more than quadrupling to 215 million units overall. Market penetration climbed to 3% overall, versus less than 1% in 2012. The DOE analysis and forecasts show the dramatic uptick in LED adoption that will take place from 2014 to 2025 and beyond.

Key to successful deployment and sustainability of 5G networks – security
10 June 2020
With this key idea and main updates in the area, the Vice-Chair and incoming Chair 2021 Michel Van Bellinghen represented BEREC at the European Cyber Security Summer Hub virtual debate on 10 June 2020.
“For the successful deployment and sustainability of 5G networks and related services, security is a key consideration. Throughout the implementation of the 5G toolbox, BEREC’s role is to assist in the development process within the NIS Cooperation Group and the Commission. We act as a conduit for information gathering in the domain of telecoms and share our experience on electronic communications market matters”, he said.
During the virtual session on 5G toolbox implementation, state of play and way forward for trust building, he provided the latest information about the implementation of the 5G Security toolbox and, underlined the role of BEREC in that process, related to the importance of trustworthy and resilient 5G networks across the EU. He also shared insights and observations from the BEREC’s perspective, elaborating on the main challenges that the actors in the electronic communications sector face.
The European Cyber Security Summer Hub is an online debate on European and global cyber security policy. This time one of the focus was the 5G security in the context of the European Commission’s Communication on Secure 5G Deployment in the EU, the so-called “5G Security toolbox”, released January 2020. It spells out concrete mitigation measures that Members States must implement in order to ensure the resilient rollout of future 5G networks across Europe.


Laptop Screen Replacement
The most common repair requirement for laptop computers is the repair or replacement of the screen. The screen can be cracked or broken if the laptop suffers an impact, and the result is a useless laptop. Fortunately, the screen can usually be replaced with a new one that matches the old, and your laptop can be restored to its former glory.
While desktop computer monitors traditionally use cathode ray tube displays, laptop monitors use LCD liquid crystal display) technology. There are three types: transmissive, transflective and reflective. Some laptop screens are widescreen, and others are backlit by LEDs.
Transmissive screens are the most common. A thin film transistor allows current to pass through it, lighting up the diodes. However, the backlight can be overwhelmed by bright lights or sunlight. This makes the laptop difficult to use in sunlight or in a brightly lit place such as a hospital or airport that has extremely harsh lighting. They are excellent for home use. Reflective screens are similar to transmissive screens use, except for the lack of a backlight. They are excellent for use in bright lighting or outdoors, but the screen may appear dim in average indoor lighting. They are usually slightly less expensive. These are often used in places such as doctor offices which require a large number of laptops and have bright lighting.
Transflective screens are composed in such a way that they act like a transmissive screen indoors and a reflective screen outdoors. This type of screen is the most expensive and least widely used. Manufacturers will often offer this option as a customizable option rather than mass producing laptops with reflective screens. They are usually purchased by wealthy students or high-level executives who need the portability of the dual screen action.
Widescreen laptops consist of a width that is 1.6 times its height, in contrast to traditional full screens that have a width 1.33 times its height. The widescreen aspect ratio is often chosen because it lets widescreen movies be played in full-screen mode. Most widescreens are only slightly more expensive than regular screen laptops as demand has risen.
Backlit LED screens to use LED lights to backlight the screen. These LED lights use less power (making the battery last longer) and are excellent for travel – but the laptops featuring backlit displays are generally more expensive.
If your laptop screen is broken or cracked, avoid the temptation to try and replace it yourself as this will generally void your warranty. Instead, seek out a qualified repair centre that can supply you with the correct size and type of laptop screen and install it safely for you. In rare cases, a slightly damaged laptop screen can be repaired, but in cases where the break or crack is large, replacement may be the best option.
An experienced repairperson can examine a laptop screen, identify the correct size and type, and come up with a replacement that matches perfectly. Some very old laptops may be harder to match, but a reasonable substitute can often be found.

Security issues in 2018 related to the Internet of Things
There has been a lot of attention based around the Internet of Things in recent years, and this is largely thanks to the fact that there is such a huge amount of potential for the way in which it could be used. The technology brings with it the ability to connect everyday devices together and share data with each other, and this data can then be used in such a way that improves the overall user experience. Some of the most obvious examples that are being adopted into homes at the moment are smart meters and smart lighting – which gives home owners a real chance to take control over the way their home is run.
Not only is this becoming increasingly prominent in a home environment, but also in business, too. Recent research has shown that 29% of businesses are already using some kind of IoT solution, with many more currently researching what it could do for them. There are a number of reasons that this kind of technology is attractive for businesses, and this includes the fact that money can be saved, and productivity can be boosted.
However, although it is easy to think about the positive reasons to make the most of IoT, many companies are failing to think about the security issues that could come with the technology. IoT means that there are more entry points into any kind of network, and thanks to the fact that there are currently no security standards set for IoT devices, it means that any home or business that has chosen to make the most of the tech leaves itself vulnerable.
If you think about a smart system that you have in your home at the moment, you will realise that the system that is used cannot be upgraded. If this is the case, then there is no way to patch anything that could make it vulnerable, and this leaves your networks open to hackers in the future. Research predicts that around a quarter of all cyber attacks will be targeted at IoT devices by 2020, which is a cause for concern.
Although this is a worry, it seems that currently the benefits of the devices mean that people are willing to take the risks in order to make the most of those benefits. Over 75% of people interviewed stated that they had some concerns over the safety of IoT devices – yet this didn’t seem to discourage installation. Furthermore, more than half of device owners have no security tools in place to protect against threats, which leaves them incredibly vulnerable.
The current situation can be compared in part to the very beginning of the internet, where companies were simply trying to race ahead to keep up with the latest tech without thinking about the dangers. The worrying aspect is the sheer amount of damage that could be caused if the technology is in the wrong hands – such as the potential for terrorists to hack into the system of a self-driving car, for example.
It is clear that action needs to be taken, and the first logical step would be to campaign for security standards that would cover all IoT devices. This means that potentially insecure devices can be identified as such. The US proposed a bill in 2017 that stated that it must be proven that devices can be patched before they are sold – and this seems to be a positive movement in the industry. There is no doubt that there is a great need for things to be standardised, and this is the best way to ensure that devices remain as safe as possible for those who choose to use them.

An international research team led by members of the Max Planck Institute for Gravitational Physics (Albert Einstein Institute; AEI) has obtained new measurements of how big neutron stars are. To do so, they combined a general first-principles description of the unknown behavior of neutron star matter with multi-messenger observations of the binary neutron star merger GW170817. Their results, are more stringent by a factor of two than previous limits and show that a typical neutron star has a radius close to 11 kilometers. They also find that neutron stars merging with black holes are in most cases likely to be swallowed whole, unless the black hole is small and/or rapidly rotating. This means that while such mergers might be observable as gravitational-wave sources, they would be invisible in the electromagnetic spectrum.

Samsung has revealed their newest computer monitor up for purchase: the CHG90. The widest computer monitor on the market, this appeals to PC gamers and computer enthusiasts alike. Many may be more or less loyal to their dual monitor setup, having more room to work and play with. Some PC gamers probably remain most comfortable with their split customization. However, there might be a new trend of wide computer monitors becoming the standard. As more and more computer users base their work and play styles on the limits of their screen capacity, wider computer monitors will fall more in demand.
The 49-inch CHG90 ultrawide gaming monitor by Samsung has a slight curve to it. The curve of the monitor helps prevent eye strain, as it keeps both left and right sides of the screen within peripheral vision. The viewing angle is 178-degrees. The aspect ratio to this monitor is wildly beyond the normal resolution, which is usually around 16:9. This monitor is at 32:9, leaving new perspectives in games. This capacity for wider views leads to a deeper immersion in game-play. In addition, photo-editing and multitasking are easier with so much increased work space.
The monitor has a reduced response time using a VA LCD panel: only a millisecond. The refresh rate is 144 hertz, which equals refreshed pixels 144 times per second. While this depends on the user’s graphics card capacity, the improvement is huge. AMD’s FreeSync 2 technology is also utilized, meaning the monitor communicates with your computer’s graphics card to create less screen tearing and unwanted choppy effects.
The monitor comes with software with ultra-customization. The screen can be split in a multitude of different directions and made to perfect the user’s needs. While this monitor is beautiful, it is hard to imagine an office full of them. It takes up massive desk space, though this monitor excels in so many other ways, making it ideal for a host of different uses.

So I have been reading about firewalls today. It can be said that it is a tool, piece of software that controls the flow of traffic between networks. They sit at the border between networks, acting as a gateway that makes decisions about the kind of traffic that should be allowed or denied access. This decision is usually done based on the TCP/IP characteristics. They also log which connections were blocked. These blocked activities are usually generated by malicious hackers running automated tools, port scanning or malwares.
Now we know the basic idea of what firewall does, lets look at different functions a firewall carries out. Here we will look at the following five functions.
- Simple Packet filtering
- Stateful Packet filtering
- Network Address Translation
- Intrusion Prevention System
Different types of Firewalls based on functionality
This is the most basic functions of firewall device. These devices inspect ingress and egress transmissions to see if their properties meet the rule set, if they meet the rules they are allowed or denied access based on action specified in the rule. Simple packet filtering operation is stateless in their operation, meaning they do not have the capability to associate multiple request or handle sessions.
Stateless packet filters are susceptible to most exploits that take advantage of the TCP/IP protocol stack. For example, many packet filters are unable to detect spoofed IP addresses. More over, some packet filters can filter packets that are fragmented, even though they are legitimate requests. (Firewalls blocking fragmented packets is a common VPN interoperabitliy issues).
The table below shows a simple rule-set for a packet filtering firewall. It is important to know that rules are applied from the top, that is when a rule that match is found, that rules is applied immediately.
|Action||Source Address||Destination Address||Protocol||Source Port||Destination Port||Control Bit|
The above rule-set allows the users to browse internet.
This type of devices improve upon the packet filters, by have an additional component, a states table. Stateful firewalls intercepts the packets at the network layer and inspect them to see if they are allowed by the existing firewall rule, while also keep a track of the packet in the state table. The state table properties vary by vendors, but most of them maintains the following properties. Source address, source port, destination address, destination port, connection state and timeout period.
Three major connection state for TCP traffic are
- Connection establishment
For stateless protocols such as UDP, which do not have a formal process of intialize, establish and termination, their state cannot be monitored at the transport layer. For such protocols, stateful firewalls are able to track the source and destination addresses and port numbers. Hence a state entry is added with a state to allow traffic, but a timeout field is added so the entry can be deleted when timeout occurs.
Application Layer Firewalls
These are the third generation firewalls that work at the application layers. The main component of this type of firewalls is stateful protocol analysis. This improves on the basic stateful inspection described above by adding a basic intrusion detection technology, i.e. an inspection engine that analyses protocols at the application layer to compare benign activities against the traffic activities. This technology is also sometimes referred as Deep Packet Inspection (DPI), as the device is now looking in to the contents of the packet, not just the header as in the previous types of firewalls. Firewalls with both stateful inspection and stateful protocol analysis capabilities are not fully-fledged IDPS, which usually have more capabilities.
An Application Proxy gateway is a feature of modern firewalls, that combines the lower layer access control with upper layer functionality. These firewalls contains a proxy agent that acts as an intermediary between two host that wish to communicate. This stops direct connection between them, each connection resulting in two separate connection. The proxy is transparent to the host. The proxy agent interfaces directly with the firewall rule-set to determine whether a given instance of network traffic should be allowed to transit the firewall.
Application-proxy gateways are different than the application firewalls in two ways. Firstly they can offer a higher level of security for specific applications, because it prevents direct communications between two hosts. And secondly, they can decrypt the packets, examine them and re-encrypt before sending the to the destination.
The main drawback of this type of firewall is that it take time reading and interpreting the packets.

updated August 1, 2019
When I last built a desktop computer in 2012, I chose an Intel Core i5-3450S processor. Since AMD's release of its 3rd generation Ryzen processors on July 7, 2019, I would choose an AMD.
The numbers make too much sense.
For example, let us compare AMD's mainstream desktop user-focused Ryzen 5 3600 to one of Intel's top consumer desktop processors, the Core i9-9900k.
In single-thread performance, CPUBenchmark.net rates the new AMD Ryzen 5 3600 at 2,823. In comparison, the Intel Core i9-9900k earns a slightly higher score (2,897). That means these processors should perform similarly at everyday tasks such as web browsing and word processing.
In multi-thread performance, the Core i9-9900k scores a 1% edge (20,215 versus 20,031) over the Ryzen 5 3600. Therefore these two processors should also perform similarly at multi-threaded tasks such as graphics, data science, and gaming.
But the processors' prices are anything but alike. At about $240, the Ryzen 5 3600 sells for about half of the Core i9-9900k. The Ryzen 5 3600 will also save you on electricity because it uses 30W less in power (65W versus 95W).
This difference exists because the Ryzen 5 3600 is based upon a technological leap: 7nm Zen 2 microarchitecture that is half the size of the Core i9-9900k's. Third generation Ryzen processors are small and therefore fast and energy efficient.
In another value-adding design choice, the Ryzen 5 3600 is compatible with dozens of existing AMD desktop motherboards. If you already own an AMD-powered desktop computer, check your specifications - upgrading may be as simple as a processor swap. If you are building a new rig, you will have dozens of motherboards to choose from.
All that said, here are three caveats:
- If you are considering buying a new computer, first think about what you want to do with it and then seek the comparisons that are most relevant for you. If you skip this step and just buy the best processor on CPUBenchmark.net or any other website, you may end up with hardware that costs more or does less than you need. I find CPUBenchmark.net's benchmarking results to be a good general starting point because they compare a huge number of processors, but they might not be the best yardstick for you because they are based upon theoretical computer applications instead of real-world usage. A different site or benchmark - for example, BAPCo's SysMark 2018 that measures general productivity - might match your needs more closely.
- Computers are more than processors. They also include other components like motherboards and memory, and unfortunately if you want or need a specific component you will sometimes be locked into one company's processors. For example if you want Optane memory, a system accelerator that gives you faster bootups and quicker access to your most-used files, you will need a supporting processor from Intel. This is basically the hardware equivalent of needing an Apple device to use iPhotos. While this practice limits our options as users, the best we can do is decide what we need and try to make an intelligent choice.
- The above analysis relates only to AMD's 3rd generation processors for desktop computers. For laptop and 2-in-1 computers, for now Intel retains its edge.
AMD and Intel have been competing for a long time, and it is exciting to see AMD offer a new line of competitive desktop processors. It will be awesome to see what comes next, in particular AMD's 3rd generation Ryzen Threadripper and Intel's new 10th generation processors for laptops and 2-in-1's, both expected for 2019 or 2020.


A device that absorbs sunlight as a source of energy and generates electricity is called Photovoltaic solar panels. These panels are packed with a connected assembly of 6×10 photovoltaic solar cells constituting an array of a photovoltaic system that transfers solar energy into electricity in commercial and household applications. While each module typically ranges from 250 to 365 Watts and its efficiency up to 24%.
The price of the best solar panel is the cheapest compared to other devices in the market. The typical price of the solar panel depends on its buyer’s range that is mid-range buyers and large quantity buyers. And these PV modules can be used in many areas such as small PV power stations, Rooftop solar PV systems, Standalone PV systems, solar planes, solar vehicles, space stations and many more.
BYD is a Chinese manufacturer of tier one solar panels with 12 year product warranties and 25 year performance warranties. They do not have an Australian office and so the company that imports the panels into Australia is responsible for their warranties.
GCL-Poly ramped up its annual polysilicon production capacity to 65,000MT and its wafer production capacity to 8GW as at the end of 2011. As for the PV power station business, the Group owns PV power stations already constructed and to be developed in the U.S., South Africa and China, with aggregated capacity of over 2GW.

Deva 24 introduces a completely new recording and mixing system that delivers unsurpassed audio quality and control. Based on its award-winning predecessors, Deva 24 integrates 24 track recording with versatile input/output routing, ZaxNet, NeverClip, PowerRoll and MixAhead with a fast, intuitive touch screen interface.
Deva 24 features 16 analog inputs, 12 are switchable mic or line level, each with adjustable limiter, high pass filter, input delay and 48V phantom power. NeverClip preamps provide 136 dB of dynamic range. Four additional line level inputs can be used as returns.
24 input channels of AES are available, 16 support AES42. With sample rate conversion, each input allows for a different sample-rate. Deva 24 accepts any unlocked AES signal with a sampling-rate of 32 to 192 kHz. The dynamic range of the sample-rate conversion is 124 dB.
10 output busses provide routing flexibility through four XLR, three TA-5M and three 3.5mm connectors. Outputs feature delay settings, level attenuation and assignable output names. 12 direct output channels of AES offers a processor independent feed to a backup recording system.
There are additional connections for timecode, external slate mic and redundant power. USB slots connect Deva 24 to the Mix-16, Oasis and RX-12.
Audio can be recorded to three media simultaneously. An internal 2.5” SSD (1TB max capacity) is the primary media paired with two compact flash (CF) card slots. Files are recorded as MARF II, a lossless fault tolerant recording format to the internal drive and as Broadcast Wave files (BWF) to the CF cards. The CF card slots can record individually or simultaneously in 16 bit or 24 bit formats. An eSATA port provides an external hard drive (SSD or HDD) option that takes the place of a single CF card slot.
12 rotary faders can be assigned to act as a fader, input trim knob or a ZaxNet control knob. Deva 24 has a three band equalizer for each input where low shelf, peaking, and high shelf can be adjusted. The rotary encoder allows you to adjust the compressor settings, input trim and invert the phase of an input.
8 tracks provide an infinite mix of all Deva 24 inputs, while 16 tracks are dedicated to ISO routing. Any of the 16 analog or 24 digital inputs can be assigned to an ISO track as either pre or post fader.
Combining Deva 24 with a Mix-16 or Oasis control surface offers a seamless integration for the sound recordist. Only a single USB cable is needed to link the Mix-16 or Oasis to Deva 24. Simply connect and go.
Deva 24 touts a detachable front panel interface with a touchscreen menu system that’s fast, easy to learn and reliable. Connecting a compatible MAC or PC allows both hardware and software components to be controlled remotely through the Deva 24 GUI by a computer mouse or Deva 24. The remote computer keyboard can be used to enter metadata. A USB cable provides the connection.
ZaxNet, PowerRoll and MixAhead provide advantageous tools for the sound recordist.
ZaxNet provides remote control over Zaxcom Digital Recording Wireless transmitters through a 2.4 Ghz RF signal. Pre-amp gain, frequency, output power and record/playback/stop functions can be adjusted without needing to approach the talent. ZaxNet is supported by an IFB200 connected to Deva 24.
PowerRoll allows ZaxNet controlled transmitters to increase its output power level when Deva 24 goes into record and then decrease its output level when recording stops. This conserves battery power on the transmitters.
MixAhead eliminates errors in human reaction time. Users can select a time up to 250 milliseconds (ms) for audio in the console to be delayed. Adding the extra time allows you to hear the audio first and then have time to react.
