Tablet computer - what is it? (Wikipedia)
A tablet computer, commonly shortened to tablet, is a mobile computer with a touchscreen display, circuitry, and battery in a single device. Tablets come equipped with sensors, including cameras, a microphone, and an accelerometer, and the touchscreen display uses the recognition of finger or stylus gestures replacing the usage of the mouse and keyboard. They usually feature on-screen, pop-up virtual keyboards for typing. Tablets may have physical buttons for basic features such as speaker volume and power, and ports for network communications and battery charging. Tablets are typically larger than smartphones or personal digital assistants with screens 7 inches (18 cm) or larger, measured diagonally.1234
Tablets can be classified according to the presence and physical appearance of keyboards. Slates and booklets do not have a physical keyboard and typically feature text input performed through the use of a virtual keyboard projected on a touchscreen-enabled display. Hybrids, convertibles and 2-in-1s do have physical keyboards (although concealable or detachable), yet they typically also make use of virtual keyboards.
The format was conceptualized in the mid-20th century5 and prototyped and developed in the last two decades of that century. In April 2010,6 the iPad was released, which was the first mass-market tablet with finger-friendly multi-touch and a dedicated operating system. Tablets experienced a rapid rise in popularity and ubiquity and became a large product category.7
As of November 2015, tablet use in the world is led by the iPad with a market share of 65.66% and Android tablets with a market share of 32.08%.8 The iPad holds majority use in North America, Western Europe, Japan, Australia, and most of the Americas. Android tablets are more popular in most of Asia (China and Russia an exception), Africa and Eastern Europe.
You should keep your computer safe. What do You really know about viruses? If You think they are not dangerous, you are in a big mistake. In fact, computer virus can destroy all your data, but damage could be worse. What can you do when your computer gets infected? First try to use an antivirus program to scan your disk, it is still possible to remove a problem. What if it will not work?
In the worst case, call for help to a computer service - they will know what to do to fix your computer and save your files.
A personal computer is a general-purpose computer whose size, capabilities and original sale price make it useful for individuals, and is intended to be operated directly by an end-user with no intervening computer time-sharing models that allowed larger, more expensive minicomputer and mainframe systems to be used by many people, usually at the same time.
Software applications for most personal computers include, but are not limited to, word processing, spreadsheets, databases, web browsers and e-mail clients, digital media playback, games and many personal productivity and special-purpose software applications. Modern personal computers often have connections to the Internet, allowing access to the World Wide Web and a wide range of other resources. Personal computers may be connected to a local area network (LAN), either by a cable or a wireless connection. A personal computer may be a laptop computer or a desktop computer running an operating system such as Windows, Linux (and the various operating systems based on it), or Macintosh OS.
Early computer owners usually had to write their own programs to do anything useful with the machines, which even did not include an operating system. The very earliest microcomputers, equipped with a front panel, required hand-loading of a bootstrap program to load programs from external storage (paper tape, cassettes, or eventually diskettes). Before very long, automatic booting from permanent read-only memory became universal. Today's users have access to a wide range of commercial software, freeware and free and open-source software, which are provided in ready-to-run or ready-to-compile form. Software for personal computers, such as applications and video games, are typically developed and distributed independently from the hardware or OS manufacturers, whereas software for many mobile phones and other portable systems is approved and distributed through a centralized online store.12
Since the early 1990s, Microsoft operating systems and Intel hardware have dominated much of the personal computer market, first with MS-DOS and then with Windows. Popular alternatives to Microsoft's Windows operating systems include Apple's OS X and free open-source Unix-like operating systems such as Linux and BSD. AMD provides the major alternative to Intel's processors.

World's first functional Quantum Computer produced at UCSB, CA
A team at the University of California, Santa Barbara has designed and tested the world's first fully functional macro-sized quantum computer.
Here is a link to the Earthfiles.com press release that highlights this amazing achievement!http://www.earthfiles.com/news.php?ID=1829&category=Science
Along with the scientific achievements of CERN's LHC (Large Hadron Collider) and certain aspects of nanotechnology, this progress represents the first major steps toward the next Quantum Age.


Below chart plots total kilobytes sent to public Internet addresses over the entire capture time. Each data point is broken by networking protocol, such as HTTP or FTP.
There are two fundamental reasons
1. In order to send correct and relavent data, servers must know clients' configuration. For example, to provide the updates that your computer needs, update servers will need to know version of your product, as well as your hardware configuration.
2. Before downloading data, client and server will exchange specifics of the transfer. For example, at the beginning of the communication, client and server will establish a transmission channel by exchanging their respective sequence numbers. Additionally, communications over a secure channel requires the collaboration of the client. For example, client sends the encryption protocols it supports, or whether or not it agrees to the options provided by the server. Also, certain communication protocols like TCP require client to acknowledge receipt of data sent by server so that server knows whether or not it needs to retransmit the data. Although these so-called ACK (for acknowledgement) are small in size, they are frequent, adding up to total traffic that is sent to the server.
Transmission Control Protocol (TCP) is the underlying tranmission protocol for most Internet bound packets. TCP is usually used as a transport control mechanism for higher level protocols (e.g. HTTP or FTP). We only report TCP if no higher level protocol was detected.
User Datagram Protocol (UDP), similar to TCP, is another fundamental tranmission protocol. UDP is usually used as a transport control mechanism for higher level protocols (e.g. DNS). We only report UDP if no higher level protocol was detected.
Hypertext Transfer Protocol (HTTP) is the backbone of web traffic. Please keep in mind that although HTTP is best known for transferring data back and forth from web sites, it is commonly used as a general purpose transfer mechanism when accessing web services (e.g. weather data, checking and downloading updates, anti-virus definition downloads)
Network Time Protocol (NTP) helps keeping your computers time in sync with highly accurate atomic clocks.
File Transfer Protocol (FTP) is used for transferring files. It is commonly used for downloading updates.
Domain Name System (DNS) is used for resolving names (e.g. www.example.com) to their IP addresses (184.108.40.206).
Please refer to Understanding Computer Networks for a more detailed explanation of how computer networks work and what the different types of packages do.
Below tables list where your traffic goes and what kind of networking protocols are being used. What makes Traffic Hound based reports unique is the highly accurate hostname informations. Most other tools either do a reverse-DNS lookup (which is bad because IP assignments change frequently and a reverse lookup may yield stale information) or only a superficial analysis of DNS packets captured earlier (which only gives CDN locations like edge.akamai.com instead of the intended destination) Traffic Hound performs a deep analysis of DNS traffic, extracts CNAME records so that intended destination names can be reported.
Moreover, Traffic Hound extracts IPv6 over IPv4 Teredo tunnels, so that real protocol information can be captured instead of the default UDP for all tunnelled IPv6 traffic.
IP address geo-location is based on heuristics. Geo-location providers use a number of databases. A primary source for IP address data is the Regional Internet Registries. These are large, official organizations responsible for managing and distributing IP addresses in specific regions of the world. However there are other sources that is employed, some of these being trade secrets of providers. Although some of these databases are high confidence, sometimes location resolutio may need to employ less accurate, low confidence resources.
We use industry standard www.MaxMind.com IP Geo-Location service to resolve location information. It is one of the most respected service providers in this field. We frequently compare their results with competitors to ensure their accuracy.

Hifi HDS providing more value-added commercial applications in addition to preventative pipeline leak detection
Hifi Engineering Inc., a developer and supplier of next generation fiber optic sensing technology used to monitor assets including pipelines and oil and gas wells, today announced the company has released the HDS Pipeline Pig Management Application (PMA) for pipelines as part of their patented high fidelity distributed sensing (HDS™) platform. HDS is a specialized data interrogation and analysis platform which uses advanced machine learning and artificial intelligence software algorithms to support Hifi’s high fidelity fiber optic sensors.
The new PMA allows pipeline operators to use the HDS 2.0 platform and web-based HDS Monitor pipeline monitoring interface to manage pipeline pig detection and tracking for their pipeline networks. Pigs are sensed and tracked automatically. The pipeline operator can optionally pre-enter pig identifying information such as a unique ID and final destination into the system. Alerts can be enabled to track the pig by time or by location, including the speed and relative strain of the pig as it travels through the pipe. The web-based HDS Monitor pipeline monitoring interface software will provide notifications to the pipeline control room if a pig stops unexpectedly and when the pig run has been completed.
"The PMA is a great addition to the HDS system,” said Ehsan Jalilian, Vice President Systems Engineering for Hifi. “This application will greatly simplify and streamline our operational processes, and will save our customers time and money through pinpointing the location of issues encountered during pigging operations.”
Hifi also announced two new patents:
US16/805,277: HDS Event Detection Algorithm
This patent covers Hifi's pipeline event detection algorithms, including its preventative leak detection algorithm. Hifi applies its leading-edge signal processing algorithms to the distributed high-fidelity data acquired from its fiber optic sensors. This patent recognizes Hifi's innovative approach to pipeline event detection, with a strong emphasis on the accurate detection of events without false positives.
US15/773,965: Versatile Pipeline Field Leak Simulation System
This patent recognizes Hifi's innovative approach to designing and conducting field leak simulations to test the effectiveness and readiness of its HDS pipeline monitoring system. The patent covers the design of an easy to deploy leak simulation system which is capable of simulating gas and liquid leaks on or near a pipeline, with maximum control provided to the operators in order to simulate leaks with various pressures, flow rates, and nozzle sizes. This innovation enables the operators to remotely trigger leaks (on a scheduled basis or on demand) and provides a feedback mechanism to notify the operator of the successful execution of the leak simulation.
“We are very pleased with both the launch of Hifi’s Pipeline Pig Management Application and these additional patents supporting the HDS 2.0 platform,” said Steven Koles, Hifi’s President and CEO. “These internally developed innovations help support preventative pipeline leak detection, as well as our other operational applications which help support environmental, social, and governance (ESG) scorecard objectives of our pipeline partners.”
Hifi will be providing a webinar for the Fiber Optic Sensing Association (FOSA) on February 18th titled “Retrofitting Existing Pipelines for Fiber Optic Monitoring”. Registration for the webinar can be made at:

What are parking sensors?
A parking sensors is an electronic parking aid that adopts an ultrasonic wave to measure the distance between your car and any obstacle, weather you have front or rear parking sensors fitted to your vehicle. When an obstacle is detected a warning signal is emmitted from a speaker/buzzer, the frequency increases as the vehicle gets closer to the obstacle, when the vehicle is around 30-40cms from the obstacle the speaker/buzzer will emitt a constant tone to warn you to stop.
Why would I need parking sensors?
We all have insurance, but we also have that annoying 'Excess' which can be £200-£300 or more, and any claims made could effect any no claims bonus, or renewal fees.
Parking sensors also give confidence in parking in tight/awkward spaces, at night or if you have neck/back problems.
If you require anymore information or would like to make a booking then please call/text 07976276021 or use our contact form.

From concept to delivery, he was involved with entire life-cycle of new technology products.


We demonstrate the stabilization of optical frequency combs (OFCs) using a segment of fiber delay line as reference. An Er-doped fiber mode-locked laser is phase locked to a kilometer-long fiber delay line using three different schemes. The short-term stability of the comb modes in the OFC stabilized by these schemes are obviously enhanced, down to 10<sup>-12</sup> level at millisecond average time. Among these three schemes, phase locking two bunches of comb modes in the OFC to the same fiber delay line exhibits the lowest residual phase noise. Fiber-delay-line-referenced optical frequency combs can provide reliable laser sources in precise metrology owing to its advances of low-cost, compactness and highly-integration.


Sputnik 1 and the InternetSeptember 1st, 2008 written by PICOL
On October the 4th in 1957, during the Cold War, the Soviet Union sent the first unmanned satellite to space. As response to that the United States commisioned the Advanced Research Project Agency or DARPA. To prevent further surprises like the launch of the Sputnik the DARPA has to build up a research network to speed up research. This network will be the ARPANET and later the Internet.
One part out of the animated documentary about the “history of the Internet” I will start soon.

PROGRAM FOR THURSDAY, APRIL 20TH

10:30-12:10 Session 8: Control II
Dynamic Periodic Event-Triggered Control for Linear Systems
ABSTRACT. In event-triggered control systems, events are typically generated when a static function of the output (or state) of the system exceeds a given threshold. Recently, event-generators have been proposed that generate events based on an additional dynamic variable, with dynamics that depend on the output of the system. It is shown that these dynamic event-generators are able to guarantee the same performance as their static counterparts, while typically generating significantly fewer events. However, all dynamic event-generators available in literature require continuous measuring of the output of the plant, which is difficult to realize on digital platforms. In this paper, we propose new dynamic event-generators for linear systems, which require only periodic sampling of the output, and are therefore easy to implement on digital platforms. Based on hybrid modelling techniques combined with constructive designs of Lyapunov/storage functions for the resulting hybrid models, it is shown that these (dynamic periodic) event-generators lead to closed-loop systems which are globally exponentially stable (GES) with a guaranteed decay rate and L2-stable with a guaranteed L2-gain. The benefits of these new event-generators are also demonstrated via a numerical example.
On a class of maximal invariance inducing control strategies for large collections of switched systems
ABSTRACT. Modern control synthesis methods that are capable of delivering safety guarantees typically rely on finding invariant sets. Computing and/or representing such sets becomes intractable for high-dimensional systems and often constitutes the main bottleneck of computational procedures. In this paper we instead analytically study a particular high-dimensional system and propose a control strategy that we prove renders a set invariant whenever it is possible to do so. The control problem---the mode-counting problem with two modes in one dimension---is inspired by scheduling of thermostatically controlled loads (TCLs) and exhibits a trade-off between local safety constraints and a global counting constraint. We improve upon a control strategy from the literature to handle heterogeneity and derive sufficient conditions for the strategy to solve the problem at hand. In addition, we show that the conditions are also necessary for the problem to have a solution, which implies a type of optimality of the proposed control strategy. We outline more general problem instances where the same control strategy can be implemented and we give sufficient (but not necessary) conditions for the closed-loop system to satisfy its specification. We illustrate our results on a TCL scheduling example.
Sound and Automated Synthesis of Digital Stabilizing Controllers for Continuous Plants
ABSTRACT. Modern control systems are by and large implemented via digital microcontrollers, which are designed to work in an embedded environment, within a dynamical plant that can present physical components. This poses a new dimension to the problem of controllers synthesis, which is classically studied in the digital control literature. In this study, we plan to provide a principled approach to extend this literature in a number of directions: we focus on automated correct-by-construction synthesis algorithms, as opposed to verification (or validation) objectives over a designed architecture; and we encompass the complete range of approximations, related to time discretisation, quantisation effects, and finite-precision representations (with related rounding errors). To this end, we propose a CEGIS-based solution that uses inductive synthesis in conjunction with a digital verification algorithm to find a parametric solution for a digital controller given a continuous plant specification.
13:30-15:20 Session 9: Temporal Logics
A Small Gain Theorem for Parametric Assume-Guarantee Contracts
ABSTRACT. The problem of verifying properties of large, networked cyber-physical systems (CPS) is beyond the reach of most computational tools today. Two common "divide-and-conquer" techniques for CPS verification are assume-guarantee contracts from the formal methods literature and input-output properties from the control theory literature. Combining these two approaches, we first introduce the notion of a parametric assume-guarantee contract, which lets reason about system behavior abstractly in a parameter domain. We next show how a finite gain property can be encoded in this form and provide a generalized small-gain theorem for parametric assume-guarantee contracts.
This theorem recovers the classical small gain theorem as a special case and its derivation highlights the connection between assume-guarantee reasoning and small-gain results. This new small-gain theorem applies to behaviors beyond bounded deviation from a nominal point to include a fragment of linear temporal logic with parametrized predicates that can encode safety, recurrence, and liveness properties. Our results are validated with an example which certifies that the interconnection of two freeway segments experiences intermittent congestion.
Relaxed decidability and the robust semantics of Metric Temporal Logic
ABSTRACT. Relaxed notions of decidability widen the scope of automatic verification of hybrid systems.
In quasi-decidability and $\delta$-decidability, the fundamental compromise is that if we are willing to accept a slight error in the algorithm's answer, or a slight restriction on the class of problems we verify,
then it is possible to obtain practically useful answers.
This paper explores the connections between relaxed decidability and the robust semantics of Metric Temporal Logic formulas.
It establishes a formal equivalence between the robustness degree of MTL specifications, and the imprecision parameter $\delta$ used in $\delta$-decidability when it is used to verify MTL properties.
We present an application of this result in the form of an algorithm that generates new constraints to the $\delta$-decision procedure from falsification runs, which speeds up the verification run.
We then establish new conditions under which robust testing, based on the robust semantics, is in fact a quasi-semidecision procedure.
These results allow us to delimit what is possible with fast robustness-based methods, accelerate (near-)exhaustive verification, and further bridge the gap between verification and simulation.
Sampling-based approximate optimal control under temporal logic constraints
ABSTRACT. We investigate a sampling-based method for optimal control of continuous-time and continuous-state (possibly nonlinear) systems under co-safe linear temporal logic specifications. We express the temporal logic specification as a deterministic, finite automaton (the specification automaton), and link the automaton's discrete transitions to the traversal of the continuous system state through specified regions over time. The optimal (hybrid) controller can be characterized by a set of coupled partial differential equations, however, it can be difficult to solve these equations in practice. Thus we propose a sampling based technique to solve the controller through an approximate value function. We adopt model reference adaptive search---an importance sampling based optimization algorithm---to identify weights of the approximate value function expressed in a finite set of basis functions. Under mild technical assumptions, the proposed algorithm converges, with probability one, to an optimal weight that ensures the satisfaction of temporal logic constraints, while minimizing an upper bound for the optimal cost. We demonstrate the correctness and efficiency of the method through numerical experiments, including temporal logic planning for a linear system, and a nonlinear mobile robot.
Abnormal Data Classification Using Time-Frequency Temporal Logic
ABSTRACT. We present a technique to extend the notion of time-frequency logic to investigate abnormal behaviors of signals in both time and frequency domains using the continuous wavelet transform. Abnormal signal behaviors such as unexpected oscillations, called hunting behavior, can be challenging to capture in the time domain; however, these behaviors can be naturally captured in the time-frequency domain. We introduce the concept of parameter time-frequency logic and propose a parameter synthesis approach that can be used to classify hunting behavior. We perform a comparative analysis between the proposed algorithm, a support vector machine approach using linear classification, and a method that infers a signal temporal logic formula as a data classifier. We present experimental results based on data from a hydrogen fuel cell vehicle application and electrocardiogram data extracted from the MIT-BIH Arrhythmia Database
15:50-17:30 Session 10: Constrained Systems
Piecewise–differentiable trajectory outcomes in mechanical systems subject to unilateral constraints
ABSTRACT. We provide conditions under which trajectory outcomes in mechanical systems subject to unilateral constraints depend piecewise–differentiably on initial conditions, even as the sequence of constraint activations and deactivations varies. This builds on prior work that provided conditions ensuring existence, uniqueness, and continuity of trajectory outcomes, and extends previous differentiability results ghat applied only to fixed constraint (de)activation sequences. We discuss extensions of our result and methods for assessing stability and controllability in piecewise–differentiable systems.
Structural Analysis of Multi-Mode DAE Systems
ABSTRACT. Differential Algebraic Equations (DAE) systems constitute the mathematical model supporting physical modeling languages such as Modelica or Simscape. Unlike ODEs, they exhibit subtle issues because of their implicit latent equations and related differentiation index. Multi-mode DAE (mDAE) systems are much harder to deal with, not only because of their mode-dependent dynamics, but essentially because of the events and resets occurring at mode transitions. Unfortunately, the large literature devoted to the numerical analysis of DAEs do not cover the multi-mode case. It typically says nothing about mode changes. This lack of foundations cause numerous difficulties to the existing modeling tools. Some models are well handled, others are not, with no clear boundary between the two classes. In this paper we develop a comprehensive and well-founded mathematical approach to the structural analysis of mDAE systems which properly extends the usual analysis of DAE systems. We define a constructive semantics based on nonstandard analysis and show how to produce execution schemes in a systematic way.
Bipedal Robotic Running with DURUS-2D: Bridging the Gap between Theory and Experiment
ABSTRACT. Bipedal robotic running remains a challenging benchmark in the field of control and robotics because of its highly dynamic nature and its necessarily underactuated hybrid dynamics. Previous results have achieved bipedal running experimentally with a combination of theoretical results and heuristic application thereof. In particular, formal analysis of the hybrid system stability is given based on a theoretical model, but due to the gap between theoretical concepts and experimental reality, excessive tuning is necessary to achieve experimental success. In this paper, we present a formal approach to bridge this gap, starting from theoretical gait generation to a provably stable control implementation, resulting in bipedal robotic running. We first use a large-scale optimization to generate an energy-efficient running gait, subject to hybrid zero dynamics conditions and feasibility constraints which incorporate practical limitations of the robot model based on physical conditions. The stability of the gait is formally guaranteed in the hybrid system model with an input to state stability (ISS) based control law. This implementation improves the stability under practical control limitations of the system, informing its practical implementation. Finally, the methodology is experimentally realized on the planar spring-legged bipedal robot, DURUS-2D, resulting in running at 1.75 m/s. The paper, therefore, presents a formal methodology that takes the first steps toward bridging the gap between theory and experiment.

Technological and interdisciplinary research at INFN Bari
Only new eyes can discover new things! Innovation is the main keyword which drives the activity of the Commissione Scientifica Nazionale 5 (CSN5). New ideas serve to develop and improve detectors, scientific devices, and experimental techniques, to be applied in experiments and in the exploration of physical phenomena carried out in the other INFN scientific commissions. While traditionally in Bari such ideas span from micro-electronics to radiation and particle detectors, now they extend also to computer science and to quantum technologies.
Interdisciplinary is another keyword for CSN5! Application of physics techniques to other fields of science, such as, for example, medicine and biology, has a relevant role in the Bari activity as well.
Sometimes an idea originated for the pure research may be extended to practical applications for industrial or commercial uses. CSN5 is the best environment where researchers can start such a process, which is later finalized within other INFN initiatives.
CSN5 keeps a particular eye on young researchers. Every year it issues a grant to finance projects of young scientists, within a few years from their PhD studies.
The Ion2neutral experiment is an integrated project for the study and development of ionization techniques in ion sources and for the neutralization of negative beams that will be used for the production of energy with nuclear fusion.
At the “Consorzio RFX” based in Padua there is an experimental source built for this purpose and the INFN-Bari has proposed, for this source, the recovery of energy from the ion beam produced with the aim of improving production efficiency energy.

MSI may be synonymous with gaming gear, but that hasn’t stopped them from trying out different things for different crowds. Their Creator lineup of laptops are powerful little beasts meant for content creators, and there’s a new member of the club in Malaysia: the MSI Creator Z16.
MSI Creator Z16 specs
You’d be forgiven for thinking that this is a gaming laptop when you look at the spec sheet, because it’s packing some pretty beefy hardware.
We’re talking an 11th Gen Intel Core i7-11800H with an NVIDIA RTX 3060 with 6GB of GDDR6 rated at 65W. This gets paired up with 16GB of DDR4-3200MHz RAM and a 1TB NVMe PCIe Gen 4 SSD for speedy memory and storage.
On the outside, the MSI Creator Z16 has a 16-inch, 16:10 QHD+ IPS display with a refresh rate of up to 120Hz. Being a laptop meant for content creators, the screen covers 100% of the DCI-P3 colour gamut and has touchscreen support too. The screen also has True Colour Technology in line with the Calman Colour Calibration to achieve a value of Delta-E < 2 for some of the best colour reproduction you can find in a laptop.
You’ll also find a 3.5mm combo jack, a microSD slot, 2x USB-A and 2x USB-C ports as well as a 720P webcam on the MSI Creator Z16. The keyboard meanwhile has per-key MiniLED RGB by Steelseries too. As for connectivity, you get WiFi 6E support along with Bluetooth 5.2. It also has a 90Whr battery and you’ll find a 180W charger in the box.
All of that gets encased in a chassis built out of CNC-milled aluminum. Weighing at 2.2kg, the MSI Creator Z16 is just 15.9mm thick, with a width of 359mm and a depth of 256mm. It comes in just one colourway: Lunar Gray.
Pricing and availability
The MSI Creator Z16 is currently available to pre-order on the MSI Malaysia online store as well as the official MSI Lazada store. All that hardware of course doesn’t come cheap, as the Creator Z16 will set you back a cool RM 11,999. Curiously, while MSI’s website lists the CPU as ‘up to 11th Gen Intel Core i9’, the Intel Core i7 is the only SKU available for pre-order right now.

Today’s vehicles have more electrical components than ever before! These components can really strain the electrical system, making it hard for the battery to keep up. The more sophisticated your vehicle’s on-board computers are, the bigger the strain on its battery. Many new vehicles have powerful computers that are operating all the time, even when the vehicle itself is parked and switched off.
Fortunately, battery technology has given us resilient batteries that are able to meet these strenuous requirements. Batteries come in “good”, “better” and “best” grades. More expensive batteries may have a longer warranty and are guaranteed to last longer. Replacement batteries come in all shapes and sizes. Some vehicles have limited space that requires a specially shaped battery to fit. Larger engines require more powerful batteries to get them started. If you live in a cold climate you will need a more powerful battery because engines are more difficult to start when it is cold.
Batteries wear out over time and eventually get to the point where they cannot hold enough of a charge to start your vehicle. The following symptoms are indicative that you may need a replacement battery:
- Dimming headlights
- Frequent need to rev engine or jump start
- Takes longer to start the engine
- Unusual power fluctuations
- Your vehicle does not start at all
When was the last time you replaced your battery? Even if your vehicle’s battery is not having issues, it is important to replace it every 3-5 years. Whether your vehicle works as new or its lights and other electronic devices are starting to show signs of age, there is no bad time to check your battery’s condition. Head over to Old Town Auto Service and ask your service advisor to test the battery and advise you on how much life it has left. We want to help keep your vehicle running and avoid roadside breakdowns.

In the early 2000s, quantum dots (QDs) lighting devices were first fabricated in the form of surface-mount-technology (SMT) light emitting diodes (LEDs) and delivered to backlights of LCD displays in order to improve their luminescence efficiency and colour quality in ITRI in Taiwan. Nowadays, they are being considered a promising solution for next-generation displays with rec. BT.2020 standards in display industry. Various application types of QDs in displays are under development, such as QD film, QD LEDs, QD photoresist or color filters, and QD electroluminescence devices, in which the QD film type has been first commercialized by the main TV manufactures. In this talk, current challenges of QDs, including colour quality, emission efficiency and thermal stability, in different application forms will be evaluated and reported.


Agenda item 1.9.1
1.9 to consider, based on the results of ITU-R studies:
1.9.1 regulatory actions within the frequency band 156-162.05 MHz for autonomous maritime radio devices to protect the GMDSS and automatic identifications system (AIS), in accordance with Resolution 362 (WRC-15);
Resolution 362 (WRC‑15) – Autonomous maritime radio devices operating in the frequency band 156-162.05 MHz
An AMRD is a mobile station; operating at sea and transmitting independently of a ship station or a coast station.
The aim of this agenda item is to prevent unregulated operation of autonomous maritime radio devices (AMRD). This will enhance safety of navigation and ensure the integrity of the global maritime distress and safety system (GMDSS). The GMDSS is the only system for distress, urgency, safety and routine communication for general shipping. Furthermore, the integrity of the collision avoidance system, automatic identification system (AIS), including the AIS VHF data link needs to be ensured.
The AMRD are grouped and identified as AMRD Group A that enhance the safety of navigation and AMRD Group B that do not enhance the safety of navigation. Signals or information which does not concern the vessel can distract or mislead the navigator and degrade the safety of navigation.
The criterion for distinguishing the two categories of AMRD is the influence on the safety of navigation. Any signal or information originated by an AMRD, which reaches the navigator, may influence the safety of navigation. This includes AIS. AIS information results in symbols to be shown on radar and on the electronic chart display and information system (ECDIS).
Four methods to satisfy this agenda item were developed.
Method A considers amendments to the footnote f) in RR Appendix 18 to allow AMRD Group A to operate on certain channels.
Under Method B, there are three approaches to consider the harmonisation of the spectrum use for AMRD Group B.
Method B1 proposes the use of channel 2006 as listed in RR Appendix 18 for AIS technology.
Method B2 proposes the use of channel 2006 in RR Appendix 18 for AIS technology and channels 2078, 2019 and 2079 in RR Appendix 18 for non-AIS technology.
Method B3 proposes the use of channel 2006 in RR Appendix 18 for AIS technology and channels 2078, 2019 and 2079 in RR Appendix 18, for non-AIS technology, with an e.i.r.p. limitation inserted in the RR.
CEPT considers that only an additions in the Radio Regulations Appendix 18 are required to enable AMRD to operate AIS technology.


After all problems we went thru with our setup we’ve solved it ourselves by buying a new CAT6 cable. Strange thing is that all computers do work with the same cable.
But for future reference, I’ll leave the complete story online:
We run our network from a Draytek Vigor 2910. We bought a printer from Saturn a month or two ago. But, as it turns out HP does not support that router. We bought a Photosmart C6280, a multifunctional printer from HP. The printer does not get an IP-address from the router, nor from one of the hubs connected to the router. All other devices ( laptops, pc’s, Macs, … ) don’t run into any problems, everything works.


If it is being eco-friendly and energy-efficient that you are after, then look no further than LED lighting.
You may have heard of LED lights but do you know what T5 lights are? The letter ‘T’ stands for ‘tubular,’ the shape of a lamp and is the simple code used to label the different sizes of fluorescent bulbs, their lamp tube diameter and their different energy-efficiency levels. T5 light bulbs are 5/8” of an inch in diameter making a T5 tube very narrow. These T5 light bulbs are deemed more energy-efficient than their T8 or T12 counterparts and are similar to power-saving eco-friendly LED lights in this sense.
Many reasons exist to upgrade your ageing lighting infrastructure that uses T12 or T8 bulbs into smarter T5 light bulbs, not least the money you could save from not having to replace and maintain the bulbs as much and pay for labour and materials. A T5 bulb has a life expectancy ranging from 30,000 to 42,000 hours depending on how you use it, making the typical T12 bulb’s 18,000-hour standard life pale in comparison.
The Lumen Factor, which is simply the amount of light a fluorescent light fixture or bulb emits, is greater in T5 bulbs than in older T12 light. This means better light quality for longer, with more modern light fixtures losing less than 20% of their light output over a bulb’s lifespan.
In fluorescent lighting, the ballast is the part which controls the current that reaches the lamp and supplies the necessary voltage to power the lamps. T5 ballasts and bulbs burn much fewer watts than T12 fixtures, providing another tempting reason for you or your business to upgrade to T5 light bulbs.
If you already have modern T5 light fittings in your property you may wish to reap the rewards of 100% recyclable, eco-friendly, durable and long-lasting LED lights and may be tempted to convert T5 to LED lighting. Being IPAF qualified, City and Guilds certified, NICEIC registered, Bannon Group can efficiently convert T5 to LED for you with minimal disruption to your business operations.
By investing in a T5 LED replacement, you can benefit from one of the most energy-efficient light sources currently available. Electricity is not lost via heat in LED fittings unlike in traditional lighting, meaning about 80% of electrical energy would be converted into light with your clean and green T5 LED replacement.
No matter if you require a T5 retrofit conversion, which adapts light fittings designed to use T8 format lamps for T5 use or are just looking to embrace LED lighting that can do wonders for the environment, our experienced electricians can install high-quality LED or T5 conversions seamlessly into your existing light fittings.
