X1 mainboard is a replacement mainboard for EPAX X1 5.5" LCD printers ONLY and uses SX03 interface to LCD screen and only support CBDDLP file format. Use with other similar printers is not supported. This is the mainboard only and does include any cables, connectors or other components.
You will need to check which version you have. There is now a version of X1-N mainboard which uses SX04 interface to LCD screen. And its firmware uses CTB file format to print instead of CBDDLP file format. Because of the way screen cable slot located, printers with X1-N mainboard has a side window outside metal body of the printer. This is so that replacing LCD screen is easier for X1-N printers.
Cannot install X-1N mainboard to X1 or vice versa. Doing so will damage mainboard or LCD screen. Contact email@example.com if you are not sure what mainboard is needed for your printer.

NightRise and image intensifier tubes
Inspired by the vision of nocturnal animals, night vision goggles (NVGs) operate on the principle of residual light amplification. Like the retina in an animal’s eye, the electronic components in the goggles capture the photons that come through the lens and convert them into electrons. These electrons are then accelerated under high voltage in a vacuum tube and projected onto a phosphor screen. The phosphor screen acts like a cathode-ray screen, retransmitting the signals in the form of images.
The type of tube depends on the type of device, and choosing the right tube — and above all the right architecture — is a crucial design decision. Thales’s world-class optro-mechanical know-how offers designers much more flexibility in the choice of tubes and lets them find the optimum combination of night vision performance and usability in the theatre of operations.
For new-generation night vision goggles, an 18 mm tube offers a number of key advantages over a 16 mm tube:
Stronger optical concentration
Higher resolution and MTF contrast
Better DRI performance
Lower sensitivity to cosmetic artefacts like black spots
On the other hand, conventional 18 mm tubes are heavier and less compact than their 16 mm counterparts, which could have a negative impact on the Size, Weight and Power (SwaP) performance of the night vision goggles. Glass-to-glass tubes, however, are significantly lighter than twisted-fibre tubes, making it possible to reduce the weight of the device, accommodate innovative architectures and offer a more compact optical design.

I finally got my Raspberry pi, and you can watch a video of it starting up with a cooling fan under tech and computers.
Christmas break has started! (For all I know, it could be the best and/or worst break in my life). That's all I have to say...
After Friday, I will be on Christmas break from my school,and I may or may not be working on a small project with my friends, which I will only be posting things in a hidden site, which you must find the url of to view.
I was playing floor hockey in gym today. I was a goal defender, so I ended up helping the goalkeeper defend about 12 pucks.
I'm still waiting for the raspberry pi though.
I know that this is completely off topic, but the only place where this belongs would be here.
Since I've been so bored for the past few weeks, I decided to build a NAND gate from individual transistors. If I don't have anything to do over Christmas, then I'm gonna build a (relatively) small calculator with more NAND gates.
It's the Christmas season again! Unfortunately, the Raspberry PI won't be getting here for about another 19 days.
I got the raspberry pi sd card. But they were out of stock when I ordered the actual raspberry pi itself. Time for more waiting... :(
I'm starting to feel that the raspberry pi got lost in the mail. I still don't have it yet... *sigh*

Led lightbulb (we had 4 colors)
3 v battery
A pencil would be nice.
First we discussed how to identify positive and negative on our led lights.
1. Fold corner of paper up.
2. Mark where battery goes
3. Draw the circuit.
Note: keep it super simple to start!
4. Place copper tape.
Note: the tape cannot touch.
5. Put LED bulb connecting positive and negative copper tape.
Bend the wires first so they lay flat somehow marking positive and negative sides
6. Place battery in marked spot and hold in place with binder clip.
7. Get excited when it lights up (or cry if it doesn’t. — don’t worry you are successful for trying and you can figure it out! Don’t give up!)
Continue experimenting. Try to make parallel and series circuits.
A parallel circuit
My attempt at a series. (It still needs work. Only one of the two bulbs will light up.:'()
Problems to watch out for:
1. Trying to go too complicated in design
2. Switching positive and negative
3. Bending copper tape
4. Using wrong color of led


pH indicator measuring liquid with color scale for measuring the pH value of liquids and water
- For setting the flow when starting up a water ionizer
- Ideal for alkaline water and other liquids.
- There is hardly any noticeable difference in color between pH 9 and 10.
- However, from pH 9,5 onwards you will taste an aftertaste in alkaline water,
more or less depending on the mineral composition of your tap water
- If the water no longer tastes pleasant, you are already above pH 10,
If it is no longer drinkable, it will slowly reach pH 10,5. A higher pH value is required with a water ionizer (except with the addition of salt) rather not possible.
- Works safely with alkaline water with hydrogen, which is not true for measuring devices, see post: Problems of measuring pH and ORP with measuring devices
- Glass pipette and glass bottle including high-quality plastic measuring cup
Does it make sense to measure the pH value and the redox potential with an electrical measuring device?
Electrical measuring devices no longer show reliable values for basic ionized active water with a redox potential of less than -200 mV.
With extremely antioxidant, hydrogen-rich water, you can “go blind” so to speak, and the measuring electrodes have to be replaced.
We created a video in our water room, which consists partly of sound and partly of video content.


New Functionality Includes Wi-Fi Lock Integration with Firmware Updates, and Better Network Security
Las Vegas, NV (April 10, 2019) – At ISC West 2019 (booth #13109), Sielox LLC is showcasing versatile new enhancements to its Pinnacle™ v.10.4 Access Control Platform. New functionality allows users to seamlessly access the features of Allegion’s Schlage Engage™ Wi-Fi locks enabling them to be easily integrated with Pinnacle Schlage Wi-Fi access platform feature. Additionally, Allegion Schlage wireless locks can now receive firmware updates through Sielox’s 1700 controller using Allegion ONR technology, which can save integrators tremendous time and money when upgrading and maintaining layered security systems using cost-effective wireless locks.
“Pinnacle v.10.4 provides a number of features that are exclusive to Sielox that further enhance the implementation and maintenance of Wi-Fi locks on our access control platform,” said Karen Evans, President, Sielox. “This, plus other new feature additions like LDAP (Active Directory) and improved security, further leverage the versatility and cost-efficiency of Pinnacle for myriad access control applications.”
Pinnacle v.10.4 provides seamless integration with Allegion Schlage NDE and LE wireless locks so they can easily be incorporated as part of a facility’s overall access control system using existing Wi-Fi infrastructure. The Pinnacle Schlage Wi-Fi integration provides access to the wireless locks’ features, enabling advanced door management capabilities along with credential management, detailed audit reports, and customizable screen layouts. With this integration, users are able to control an unlimited number of Allegion Schlage NDE and LE wireless locks, manage cardholder records, create access groups, define holiday schedules and more. Additional Schlage wireless lock fields are now reported in Pinnacle providing users a single dashboard to monitor the lock status.
An industry first, Allegion Schlage™ NDE and LE wireless locks can receive firmware updates when using the Sielox 1700 Controller Allegion ONR feature via RS-485 communications. By pushing the ONR Firmware Package for Allegion Schlage wireless locks using 1700 Controllers, users and integrators can save both time and money.
Sielox has also added a new Transport Layer Security (TLS 1.2) enhancement to Pinnacle v.10.4. TLS, and its predecessor Secure Sockets Layer (SSL) for improved network security. TLS/SSL operates by establishing an encrypted communication path between two applications, “wrapping” the entire application protocol inside the secure link. This provides complete privacy for the entire transaction so that sensitive information is protected from unauthorized access while in transit. Pinnacle TLS 1.2, which is available to current Pinnacle users, provides compliant level security.
An additional update to Pinnacle v.10 includes Lightweight Directory Access Protocol (LDAP), a licensed service that can be installed on the same server as Pinnacle. The feature simplifies administration by assigning roles to users with permissions, which makes the overall solution more efficient and easier to use for larger security systems. Pinnacle 10.4 will be released in Q2 2019 and is available in several configurations that can be specifically tailored to the needs of any size business or facility, or integrated in a layered systems model.


Image processing is a method to convert an image into digital form and perform operations on it and in order to get an enhanced image or to extract some useful information from it. It is a type of signal dispensation in which input is image, like video frame or photograph and output may be image or characteristics associated with that image. Usually Image Processing system includes treating images as two dimensional signals while applying already set signal processing methods to them. It is among rapidly growing technologies today, with its applications in various aspects of a business.
Image Processing forms core research area within Engineering Computer Science disciplines too . Image processing basically includes the following three steps 1. Importing the image with optical scanner or by digital photography. 2. Analysing and manipulating the image which includes data compression and 3.image Enhancement and spotting patterns that are not to human eyes like satellitephotographs.4. Output is the last stage in which result can be altered image or report that is based on image analysis.

The Ozobots are now part of the Makerspace!
In November, Brookfield was selected to be a part of the Asha-Jyothi 2019 Innovation Lab/Maker Space grant. Asha-Jyothi is a volunteer-based non-profit focused on providing access to education and healthcare. With the very generous $1800 award, we were able to expand our Makerspace. We purchased a set of Ozobots. These small, spherical robots allow students to practice the basics of coding.
In January, the Brookfield Makerspace introduced the Ozobots. Students learn to code the robots by drawing paths on grid paper for the robot to follow. They can change the paths by using combinations of four different colors for the robots to “read.” Please take a look at some of our students as they explore this fantastic STEM activity.


CONVERTING THE BEHRINGER
DD-400 DIGITAL DELAY GUITAR PEDAL
TO A SYNTHESIZERS.COM PANEL MODULE
by Dana Countryman
Now, a little discussion.
I've had problems in the past, when
I've tried to convert a guitar pedal into a modular synthesizer-format
module. When desoldering parts
to remove from the PC board, it's very easy to tear the delicate
copper wire tracings, and mess up the board. I would wholeheartedly
discourage you from
considering removing the audio and power connectors by de-soldering
ALSO, they coated the PC board with
a dark blue coating of some kind of protective spray.
This makes it extremely difficult to SEE the copper tracings of
the PC board, if you DO need to repair a broken tracing connection.
And the tracings are on BOTH sides of the board ("through-hole".)
Finally, this guitar pedal is ROHS-compliant.
Meaning, ithe PC board does not use lead-based solder.
Instead, they used another kind of solder - probably Silver Solder.
Your usual soldering gun will not get hot enough to efficiently
melt this stuff. You will, however still need to de-solder the
pot casing lugs.
For that, you will need a hi-temp soldering unit: one that will
get to (at least) above 270 degrees Farenheit.
I bought a battery-powered hi-temp soldering gun from Radio Shack
for about $19.
It will work fine on ROHS-compliant solder, without your spending
an arm and a leg.
Be very careful, when desoldering.
Almost every connection has MICRO-resistors and capacitors laid
across the solder joints. If you mess up even ONE of these connections
up, your entire unit may be rendered non-functional.
The ONLY connections I
recommend desoldering, are the Potentiometer Casing Lugs. See
The larger Pot Casing Lugs are anchored in solder. These must
be removed. The smaller connections that I've marked below, are
potentiometer terminal connections. Your goal will to be to desolder
the pot casing, destroy the potentiometer by chopping it up,
and LEAVE the pot resistor terminals intact, and still soldered
into the board.
A word of warning: the resistor
terminals of the pot are very brittle, and easy to break away
from the board. Try not to wiggle them too much.
I accidentally DID break off two of the connections, and was forced
to have to wire directly into the board in two places.
You will need some kind of magnifier visual aid, unless you have
REALLY good vision! These connections are TINY! Be CAREFUL!
SO, once again, I recommend that
you DO NOT disturb the solder, installed by the actual robots
at the Behringer factory, unless you REALLY have to!
Here is a pot in the process
of being desoldered away from the board. You see one leg of the
desoldered, and bent up and out of the way. I wedged a small screwdriver
under the pot, as I was desoldering
its anchor underneath, and carefully applied pressure to raise
the pot up, until the support leg was out of the board.
A pot, with both sides
of its anchors removed from the board, leaving the original pot
resistor terminals still attached to the PC board.
Another view of a pot, in mid-destruction. It's tight, around
all those condensers, so you really have to take your time and
Using wire cutters, start chopping away at the potentiometer.
Being plastic, phenolic, and cheap alloy, it chops up, quite easily!
Now, the first pot has been removed (to the right of the power
connector.) You'll see the three remaining pot terminal parts.
This is all that you want to leave behind, from each pot!
Here's an advance peek at the replacement pots. I soldered wires
to them, awaiting connections to the PC board.
You will need 50k Linear potentiometers. Try not to order
center-detent replacement pots.
Your goal is to solder your new leads to the old pot teminals,
and leave the PC board connections underneath intact.
Use 20-gauge braided copper wire, if you can. I only had solid-core
wire, and you need very flexible wire for this project.
Wire-wrap type wire would work great, too. (I ran out!) (Regular
lead solder will work, if you still have it).

The acquired data is processed using ESP32 and uploaded to ThingSpeak for future viewing and analysis. However, one of the key challenges faced by e-health devices is limited battery life. Optimizing battery usage is crucial to ensure uninterrupted monitoring and enhance the usability of e-health devices. This write-up provides an improved e-health monitoring device for vital signs measurement using users’ engagement and behaviour modification techniques
This study was carried out to evaluate the effect of germination period on the nutrient and anti-nutrient contents of red and brown pigeon pea flours. The red and brown pigeon pea seeds were cleaned, steeped for 6, 8 and 10 h and germinated for 48 h, 72 h and 96 h, respectively and processed into flours, while the flours produced from the ungerminated red and brown pigeon pea seeds were used as control samples. The flours obtained were analyzed for proximate, mineral, vitamin and anti-nutrient contents using standard methods. The proximate composition of the samples showed that the flours produced from the red pigeon pea seeds had a range of 6.24 – 9.34% moisture, 10.37 – 20.95% crude protein, 1.21 – 1.12% fat, 2.32 – 3.32% ash, 3.14 – 4.23% crude fibre, 76.75-61.07% carbohydrate, and 329.29 – 338.10KJ/100g energy, whereas that of the brown pigeon pea flours had a range of 6.44-9.77% moisture, 10.47-23.69% crude protein, 1.23-1.13% fat, 2.42-3.13% ash, 3.18-4.31% crude fibre, 76.26-57.99% carbohydrate and 358.18-336.83KJ/100g energy respectively. The mineral composition of the flours produced from the red pigeon pea seeds had a range of 103.85-118.76 mg/100g calcium, 213.10-236.75mg/100g potassium, 140.30-165.40mg/100g phosphorus, 114.04-132.79mg/100g magnesium, 7.97-10.94 mg/100g sodium, and 5.08-6.49 mg/100g zinc, while that of the brown pigeon pea flours were 107.95-121.22 mg/100g calcium, 2.57-293.21 mg/100g potassium, 140.30-199.08mg/100g phosphorus, 118.12-152.67 mg/100g magnesium, 8.33-11.64 mg/100g sodium and 5.19-7.99 mg/100g zinc respectively. The vitamin composition of the red pigeon pea flours showed that the ascorbic acid, thiamine, niacin, riboflavin, folic acid and vitamin A ranged from 3.53-4.63mg/100g, 1.17-1.46 mg/100g, 2.16-3.20 mg/100g, 1.02-1.36 mg/100g, 1.08-1.28 mg/100g and 2.13-2.57 mg/100g, whereas that of the brown pigeon pea flours ranged from 3.97-4.96 mg/100g, 1.36-1.71 mg/100g, 2.46-33 mg/100g, 1.18-1.48 mg/100g, 1.10-1.35 mg/100g and 2.19-2.94 mg/100g, respectively. The anti-nutrient composition of the flours from the red pigeon pea seeds showed that the levels of trypsin inhibitor, tannin, phytate, oxalate, saponin and haemaglutinin were 7.66-1.03 Tiu/g, 1.34-0.78 mg/kg, 4.78-1.15 mg/kg, 3.03-0.45 mg/kg, 2.78-1.21 mg/kg and 7.44-0.30Hui/g, whereas that of the brown pigeon pea flour ranged from 6.33-1.15Tiu/100g, 1.14-0.41mg/kg, 3.98-0.26mg/kg, 2.99-0.17mg/kg, 2.60-1.11 mg/kg and 6.23-0.33 Hui/g, respectively. The result generally showed that the nutrient contents of both the red and brown pigeon pea flours increased significantly (p˂0.05) with increase in steeping and germination time, while their antinutrient contents decreased drastically compared to the raw (control) samples in both varieties of pigeon pea flours. However, the brown pigeon pea flours relatively had high nutrient contents than the red pigeon pea flours, hence, they could be widely utilized in the preparation of a variety of good quality and nutrient-dense food products than the flours derived from red pigeon pea seeds
This paper details the simulative analysis of a high-speed microwave point-to-point link boasting a data rate of 474.62 Mbit/s over a distance of 47 km. The paper considers University of Port Harcourt (UNIPORT) as Site A and Rivers State University (UST) as Site B. The aim was to devise a robust communication system to facilitate seamless communication network between these two university campuses. The design process involved meticulous consideration of factors such as antenna selection, modulation scheme, and link budget analysis. These considerations were tailored to suit the geographical and environmental characteristics of the chosen sites. Radio link planner simulation tool played a pivotal role in evaluating the system’s performance across various scenarios, taking into account terrain obstacles and weather conditions. The results conclusively demonstrate the feasibility of establishing a reliable microwave point-to-point link between UNIPORT and Rivers State University. The study includes calculations of Signal-to-Noise ratio (SNR) of 1.09 × 10-4dB, percentage reliability of 99.9999964% and an assessment of the Bit Error Rate (BER) graph to gauge signal quality effectively. These findings underscore the system’s capability for high-speed data transmission, thereby fostering improved connectivity and collaboration between both of the academic institutions.
This research centers on the implementation of fuzzy logic for dynamic spectrum allocation (DSA) within cognitive radio networks (CRNs), specifically tailored for Internet of Things (IoT) applications. The ever-growing number of IoT devices and the limited availability of spectrum resources necessitate sophisticated and efficient spectrum allocation methods. Cognitive radio technology facilitates unlicensed secondary users in accessing underutilized spectrum bands, and DSA enables the dynamic assignment of spectrum resources based on demand and availability. Leveraging the capabilities of fuzzy logic, renowned for handling uncertainty and imprecise data, the system intelligently makes decisions concerning spectrum allocation, taking into account factors like signal strength, interference, user priority, and channel conditions. The outcomes demonstrate that the proposed Fuzzy Logic-based approach adeptly balances channel availability and interference levels, resulting in a substantial enhancement in Quality of Service (QoS) satisfaction. The QoS satisfaction percentage is computed over the simulation period, offering insights into the overall performance of the system. The simulation results are visually presented through a time-dependent spectrum allocation matrix, providing a lucid representation of how the system adapts to varying conditions. This study and its findings underscore the significance of adaptive and intelligent systems in optimizing spectrum usage, especially in the context of emerging IoT applications
The alarming rate of insecurity of lives and property globally is of great concern to all and sundry. Burglary is one of the most common criminal activities that is causing significant financial and emotional damage in local environment and households, several methods and devices have been developed to overcome this problem. The use of burglar alarm systems as a means of enhancing security cannot be overemphasized as safety of human lives is as important as food, clothing and shelter. Though several security alert systems have been invented in the past, there is still need for more efficient devices to ensure the reduction of insecurity of lives and property to the barest minimal. Hence, the need for innovative devices capable of mitigating this menace of insecurity especially in homes. This work is the development of a security alert system capable of effectively detecting an intruder, after which the security light is turned on, alarm is triggered and an automated voice is played through the speaker depending on the mode of operation the device is switched to. The components of the developed Security Alert Device are: Ultrasonic Sensors, Power Supply Circuit, Microcontroller Circuit, Speaker, Buzzer, Security Light and SD card Module. The device was tested after coupling and it perform excellently, also the overall cost was far lower than the existing price of similar devices in the market.
Poor waste management is one of the factors that had significant implications for public health. Currently, the process of solid waste collection in most urban cities of developing countries is curbside collection and is marred with poor disposal infrastructure, time consuming and high transportation cost. The study proposes a cloud-based big data repository for solid waste management in Owerri metropolis, Eastern Nigeria, by using a decision tree algorithm for optimizing collection routes. This system will consider factors such as: data storage, real-time processing, cloud resources, data sources, GPS data integration, user accessibility data analytics and reporting. The proposed system will make use of machine learning with decision tree algorithms for waste classification and route optimization, Azure Power BI for data visualization and reporting, and service-oriented architecture with Microsoft Azure platform as a service (PaaS) and Python programming. Azure Data Factory will provide secure and scalable data storage, and IoT Hub will automate the process of ingesting data from bin sensors, IoT devices, or manual data input. In order to ensure optimum use of disposal infrastructures, minimize transportation costs related to trash collection, and increase labor productivity, the system will assist in optimizing waste collection routes for an efficient and effective waste collection process
This paper presents the improvement of energy efficiency for mobile ad-hoc network (MANET) using a rule-based optimization (RBO)algorithm and quality of service compensation routing (QSCR) algorithm. The aim is to improve energy efficiency in MANET, while sustaining other quality of service parameters like throughput, and latency. To achieve this, the rule-based optimization algorithm, which is an energy saving algorithm was first developed and its performance on the improvement of energy efficiency in MANET tested by simulation using matlab software. Based on an observed trade-off between energy saving and quality of service (QoS) in using RBO algorithm, the quality-of-service compensation routing (QSCR) algorithm was also developed using ad-hoc-on-demand distance vector (AODV) and integrated with RBO to improve Quality of Service (QoS) in MANET nodes while still maintaining good energy saving resulting from RBO algorithm only. The performance of the algorithm was also tested bymatlab simulation on the nodes. The result of simulation of the integrated algorithm over 100minutes of communication for throughput reported at 85.40Mb/s, 13.60ms for latency, 49.8475% for remaining energy level and 5.3236J/secs for energy consumed. The result was validated using k-fold cross validation approach and validation results reported 85.203% throughput, 13.391ms for latency, 49.0765% energy level remaining and 5.25960J/secs of energy consumed. From the result, it was observed that while there is still room for improvement for energy consumption rate, other QoS parameters such as throughput and latency were sustained at very good levels respectively. Recommendations were made to focus on the RBO and further improve the rate of energy control, while integration with QSCR algorithm for a holistic QoS in MANET…
This study was carried out to ascertain the acquiescence of structures used for agricultural activities in Nigeria, to International guidelines for residential and industrial buildings. In this research structures used for agricultural productions within the Niger Delta region of Nigeria, were appraised to determine their integrity status. Results obtained from the field survey revealed that most of the farm structures within the studied region were constructed with outright disregard to the basic civil and electrical engineering guidelines for buildings construction. It was observed that only 9% of the farm structures were constructed after adequate geotechnical evaluation of the building sites’ soil, 28% of the farm buildings had foundation designs, 89% of the concrete used for the buildings construction did not pass through integrity tests, and 92% of the wall materials (sandcrete blocks) did not undergo mechanical strength tests, to ascertain their suitability for load bearing walls construction. Furthermore, the field observations revealed that 90% of the farm buildings’ electrical wiring was done without any electrical design, 58% of the structures investigated were lacking electrical safety devices, 63% of the materials used for electrical installations were fake electrical materials; while 29% of the electrical terminals were not well secured. Also the findings from the questionnaires administered to the public, established that economic situation and quackery are the major reasons why people use substandard materials for construction of structures
The power distribution system is the bridge between the ultimate power users (humans) and the source (generation of power). Therefore, data acquisition from distribution network and their processing for the purposes of monitoring and control of the distribution equipment, lines, voltage and current status in the network, giving rise to the optimization and synchronization of power distribution system for efficient power delivery is important. For advance monitoring and control of the power distribution system from the remote injection substation by substation engineers, a real-time monitoring and control device located at the substations is further designed and simulated with the Proteus Electronics Suite. The data captured by the local monitoring device through its sensors located at transformer substation is transmitted by wireless mean to the monitoring and control unit in the injection substation. The parameters monitored are transformer temperature, transformer oil level, transformer voltage input and output and line voltage, current and faults. The upper threshold value for temperature is 650, voltage of 270 V and current of 300; whereas, the lower threshold value for oil level is 270 litres. Result clearly showed that the designed local monitoring device could efficiently measure the target parameters and classify into “LOW, HIGH OR NORMAL”; relay the data to the control substation and disconnect the substation on a fault condition inimical to the distribution system. The local monitoring device located in the substation complements with the existing state estimation system in the injection substation to improve the monitoring, control, and protection of power distribution system.
Geotechnical investigations of subsoil were carried out in parts of Oleh community, Delta State, Southern Nigeria in order to delineate subsoil engineering properties, as well as evaluate the type of foundation that will be most suitable for the area. A total of ten (10) subsoil samples, obtained from two (2) depths (4 m and 8 m) were used to determine the specific gravity, Atterberg limits and particle size of the subsoil. The findings revealed that the specific gravity of the soil samples ranged between 2.52 and 2.85; and the specific gravity of the soil obtained at the 4 m depth was higher, when compared to the soil obtained at the 8 m depth. Additionally, the liquid limits of the soil samples ranged between 25% and 42%; the soils samples plastic limit varied between 13% and 25%; soils samples plastic index ranged from 5% to 17%; and the liquid limit, plastic limits and plastic index of the soil samples obtained at the depth of 4 m, were generally higher than the soil samples obtained at the depth of 8 m. The findings of the particle grain size grading revealed that the study area consists of silt loam, loamy sand and sandy and soils. Data obtained from this study will be useful for geotechnical purposes and these results will benefit to engineers or decision makers in designing building foundation within the study region

The most important aspect of installing a CCTV camera … This specification comes from the video broadcast market rather than the security market and can be totally confusing. If you increase the shutter speed to 0.5 seconds, the maximum frame rate is only 2 fps. To confuse us, some manufacturers specify their 3-megapixel or 5-megapixel camera as â1080Pâ as well. If you want to detect that a door has been opened and start recording video, then you will require an IO input connection to the camera. IR Corrected Lenses: Lenses bend the light to achieve the right focus and magnification. Check out our short guide below to help you with your choice. Solution 3: IP Camera with PoE – NVR – Router. The pixels are organized in a matrix of horizontal and vertical pixels. The frame rate can also be affected by very low light situations. It provides Plug & Play Ease of Use. The âpâ indicates “progressive” rather than “interlaced.” The older TVs used two interlaced fields to make one frame. PC requirements for 3-1. contrast 4-5. Planning before installing a CCTV camera. Getting Started Minimum System Requirements Security Camera H.VIEW 5MP IP Camera with 2.8mm Lens Super HD Dome POE Outdoor Camera, Audio, H.265, Motion Detection, Smart IR, Easy Setup, Easy Install 4.0 … The relationship between the horizontal and vertical pixels is called the aspect ratio. In general, security cameras, either CCTV analog cameras or PoE IP security cameras, are not energy-consuming as other gadgets like computers or bread toasters; they only need a very little electricity to work. Finally another standard called IEEE 802.11n came out and kept the same 2.4 Ghz frequency but increased the speed from 54Mbps to 300Mbps and now the new computers and laptops could also use such standard. CCTV Mounting Brackets. By increasing the time that the shutter stays open, you can improve the low light performance of most cameras. The lens also can affect some of the other specifications such as minimum illumination, frame rate, and resolution. The traditional and well recognized type of IP Camera is the Pan and Tilt, which requires the user input to move the camera to wherever he wishes to look into. Be careful. IP cameras can be powered near the installation point with 12V DC adaptors, or can utilize PoE technology in the PoE switch that provides power and data from one convenient device and over one cable. For example, a 1.2 Megapixel sensor on the Sony SNC-EM600 camera has 1280 horizontal pixels and 1024 vertical pixels. If you plan to use a megapixel IP camera system, then make sure you get the IR type lens. This is a list of relevant British, European and International standards for installers and maintainers of surveillance cameras. In certain cases, the frame rate has to be reduced. But, which specifications are important? The longer the shutter is opened the more light can reach the sensor. The angle of the lens depends on the size of the sensor and the distance from the sensor to the lens. The lower the f-number of the lens the more light it will let through. You can also select a camera with a built-in microphone, but be careful because itâs always best to have the microphone close to the person talking. DVR/NVR tend to use a bit more than CCTV security camera or PoE security camera. This crossover of IP cameras to home use is partly due to the device’s self-installation. Contact our support if you prefer a special camera type. IP cameras are Digital and connect via Cat5 (Networking) Cable or WiFi. If you plan to release a door lock, you need an output signal to control a relay that can open an electric lock. Transmission 36 4.1 Wired Transmission 36 4.2 Wireless Transmission 39 4.3 IP Network Transmission 42 5. The better manufacturers also include the relative level of the signal (IRE), which is a measure of how hard the amplifier has to work. Our team of security experts will help you learn how to install security cameras, including where to place the cameras, as well as overall installation tips. This article reviews the important camera specs, and how to avoid being fooled by specsmanship (from the marketing department). Kintronics provides everything you need to create a complete surveillance and security system. In many cases you donât have to pay more for this capability, you just have to select the right camera. Planning. The 1080p HD camera has at least 1080 vertical pixels (or horizontal lines). The p-iris lens prevents the lens from opening all the way and compensates by increasing the camera amplification of the video signal. CCTV Power Supplies / Battery Packs / Converters and much more. Take a look at our video âHow the Video camera Worksâ for more details about frame rates and how they have evolved from the old days of TV. A camera with an f-number of f1.2 can pass more light than one that has f2.0 lens. After identifying them, you can mount the camera and junction box, please note that some cameras may have a deep base for cable management, but this particular camera needs a junction box to hide cable connections like RJ45 connectors and power leads. It has approximately 4,000 horizontal pixels. Either system can have recording capability, but the equipment will be different. Once you know the distance and field of view, you can select the right lens. Hereâs what each of the terms means: Megapixel Camera: This is a general term used for any camera that has over 1 million pixels in the sensor. On the other hand, large businesses and commercial spaces, like malls, require high-resolution videos (i.e., 4K), many cameras, and professional applications to accommodate the installation and management of the cameras. Marketing people also use the term âHDâ and â720pâ or â1080pâ, and most recently â4Kâ. The Hanwha (Samsung) PNO-9080R has a resolution of 4000 x 3000 pixels. Pole-mounting: Two metal straps (not included) Shielded Category 5 (or above) cabling with drain wire should be used for all outdoor wired Ethernet connections and should be grounded through the AC ground of the PoE. It depends on what you think is an acceptable image. IR light can bend at a different angle than visible light when the wrong type of glass is used in the lens. The focus of the IP camera can be adjusted either by manually adjusting the lens or by remotely adjusting the distance between the lens and the sensor (back focus). accessing 4-5. description 4-2. displaying 4-2. connecting, to the IP camera. The DC auto Iris lens is usually used with outdoor cameras. Well, it depends on the application. IP Camera manufacturers provide product specification sheets that help you select the right camera for your IP security and surveillance system. The low light level image you see is not only dark but can also be very noisy. The number of vertical and horizontal pixels and the aspect ratio are defined differently. International: 914-944-3425
The aspect ratio is 1280/1024 which is 1.24 or close to the 4/3 ratio (1.3). The lower the IRE number, the harder the amplifier has to work to boost the signal so it can be seen. Ensure that the camera: 1) Is a dome or positional type as specified in the contract. It is a good idea to draw a floor plan with camera locations, this will help you in deciding what type of cameras to buy. IP cameras are gaining in popularity for its high definition picture quality, they are not expensive as they were in the past, many CCTV installers have started using IP cameras. âBack focusâ is not part of the lens, but is usually listed with the lens specification. It can be very confusing. The importance of each of the camera specifications depends on your objective and application for your IP camera system. Home window. The lens allows you to frame the area that you want to see. for the first time 3-1. 1080p cameras have at least a 2-megapixel sensor, and it is considered to be the higher resolution âHD cameraâ. In the old days, the resolution was measured in TV lines, and they used a TV test pattern to analyze the resolution.

Martin Stolterfoht is a Heisenberg fellow funded by the German Research Foundation and leading the Perovskite Group at the University of Potsdam. He completed his Master’s degree in Physics at the University of Graz, Austria in 2012 and obtained his Ph.D. at the University of Queensland, Australia in 2016. His research is focused on providing a fundamental description of thin-film solar cell operation and charge recombination processes from picoseconds to steady state through electrooptical measurements and numerical modeling. He also aims at improving perovskite single and multijunction solar cells through the identification and suppression of recombination losses.
Perovskite semiconductors differ from most inorganic and organic semiconductors due to the presence of mobile ions in the active layer. Although the phenomenon is intensively investigated, important questions remain, such as the dominant species and overall density of the mobile ions and their exact impact on the steady-state power conversion efficiency (PCE) and device stability. To estimate the efficiency loss due to mobile ions, we propose a simple method based on “fast-hysteresis” current-voltage measurements to prevent the perturbation of mobile ions out of their equilibrium position at fast scan speeds (1000 V/s) and choosing a suitable prebias condition.[1,2] The ”ion-free” PCE of fresh pin-type cells with low levels of apparent hysteresis at typical scan speeds (100 mV/s) is between 1.5-3% higher than the steady-state PCE. However, with device aging, e.g. under elevated temperatures or continuous light illumination, the ionic losses increase substantially, which represents the dominant degradation loss of a triple cation based pin-type perovskite cell. The enhanced ionic losses with aging are also accompanied by a significant increase of the mobile ion density. I will also discuss the role of interfacial recombination to the total degradation loss as well as the impact of the perovskite stoichiometry and in particular the PbI2 excess and how these losses vary with the charge transport layer properties. Finally, an outlook is presented on how these losses affect the degradation of solution processed perovskite based tandem cells. Overall, the proposed methods to quantify the ion-induced field screening and PCE losses allow for a better understanding of several key phenomena in perovskite solar cells and shed light on the complex device degradation process.

Nu Plasma 1700: Large Geometry Multi-Collector Inductively Coupled Plasma Mass Spectrometer
The application of non-traditional stable isotope systems such as Mg, Si, S, K, Ca, Ti, V, Cr, Fe, Ni and Se in geochemistry, cosmochemistry and life sciences has been spurred by the advancement of the multi-collector ICP-MS (MC-ICPMS) over the last two decades. This versatile technique, although widely considered as the standard method for the high precision isotopic analysis of such systems, is limited by the inevitable molecular species generated by the ICP source resulting from ions such as Ar+, N+, O+ and H+. These species can often interfere directly with the atomic ions of the same nominal mass, leading to inaccurate isotope ratio determination. The ability to avoid unwanted interfering species in close proximity to the target ions on the mass focal plane is dependent on the mass resolution. Such interfering species are partially resolved by narrowing the source entrance slit to proportionally increase the mass resolution.
Narrowing the source entrance slit has the unavoidable consequence of decreasing the ion beam intensity. The natural size of the focused ion beam entering the mass analyzer is ~0.3mm, reducing this dimension proportionally reduces the ion beam intensity in a way that can not be recovered. A larger magnet and geometry results in a bigger mass dispersion which increases the base resolution of the instrument. Nu Plasma 1700 has a mass dispersion of ~1700mm, giving a base resolution of >800 (10% valley definition), much higher than any standard MC-ICP-MS. This is sufficient to analyze nearly 40% of isotopes while operating at full sensitivity. Comparing to any standard MC-ICP-MS, the ion transmission is much higher on the Nu Plasma 1700 for a given resolving power. The source entrance slit is continuously adjustable, allowing a suitable resolving power to be chosen to analyze a certain isotope system, without unnecessary sacrifice of transmission. The edge resolving power can go up to >30,000 (5, 95% edge definition) making most isotopes measurable.

True High Resolution
The Nu Plasma 1700 has a unique true high resolution capability, utilizing independently adjustable collector slits fitted for each detector. Interfering peaks are completely resolved from analyte peaks, whilst maintaining a flat top profile. This is critical in cases when polyatomic interferences appear on the high mass side and doubly charged interferences on the low mass side of the analyte peaks, often observed in laser ablation mode.

The SIRGAS reference network is weekly processed; station positions are daily computed, and the seven individual daily solutions corresponding to a GPS week are combined in one weekly solution. The SIRGAS stations are classified in a core network (SIRGAS-C), with a continental coverage, and several densification networks, which correspond to the national reference networks (SIRGAS-N). The SIRGAS-C core network is processed by DGFI-TUM. The SIRGAS-N national networks are computed by the Latin American SIRGAS Processing Centres. The loosely constrained weekly solutions individually calculated for the national networks are combined with the loosely constrained weekly solution calculated for the SIRGAS-C core network to obtain compatible station positions and velocities in a continental level.
In addition to process the SIRGAS-C network, DGFI-TUM is responsible for combining the core network with the individual solutions delivered by the other SIRGAS Processing Centres. The main characteristics of the DGFI-TUM combination strategy are:

Verity’s Trifecta Of Technology
Internet of Things (IoT), Blockchain and Artificial Intelligence (AI) are the three most groundbreaking emerging technologies in today’s tech industry. Verity cohesively employs all three in order to increase efficiency, transparency, and legitimacy in product assertions; namely, Made in USA, Organic, Halal, Kosher, and Vegan claims. Each of these technologies has immense potential and is deserving of the attention surrounding them. However, when applied simultaneously this tech trinity can be earth-shaking.
First, let’s clearly define Blockchain, Internet of Things, and Artificial Intelligence, then we will discuss their joint utilities.
The Blockchain is an immutable, decentralized ledger of all transactions. The transactions are replicated across multiple computers making record tampering virtually impossible.. This immutable mode of record administration eliminates the need for any central entity to manage the transactions. Instead, the decentralized network manages itself. This eradicates the need for a trusted third party to manage and protect data, which also means blockchain eliminates the ability of third-party entities to potentially corrupt data. Verity uses an IBM Hyperledger Blockchain custom tailored to be the industry leading software in blockchain based supply chain management.
The Internet of Things (IoT) is a network of physical devices that are connected to the internet and thus communicate with each other. IoT is comprised of a diverse range of devices and everyday gadgets that utilize embedded technology to communicate and interact with the external environment, all via the Internet. Verity takes full advantage of IoT technology by using this highly advanced digital communication network to track and trace products across the supply chain in an extremely efficient and precise fashion. For example, our IoT devices can monitor slight temperature changes inside of shipping containers, which can be crucial to the well-being of the product.
Artificial intelligence is when a computer mimics human cognitive functions such as “learning” and “problem-solving”. Artificial intelligence can be used to monitor data autonomously, which eliminates vast amounts of manpower. The future of artificial intelligence is limitless and Verity plans to be at the forefront by using IBM’s Watson artificial intelligence software for sophisticated analytical problem solving and database management.
BENEFITS OF USING BLOCKCHAIN WITH IOT
Blockchain’s decentralized nature allows people to trust each other and transact peer to peer. As autonomous systems and devices interact with each other, the IoT transactions are exposed to potential security risk. If these transactions were made on the blockchain the data would be decentralized across computers all over the world making the sequences virtually unhackable. Blockchain technology gives a simple, cost-effective, and permanent record of decisions made and communicated on IoT devices while diminishing the possibility of security breaches or tampering.
- Transparency and Trackability
Data transactions take place between multiple networks owned and administered by multiple organizations. Blockchain can provide a permanent, immutable record so that custodianship can be tracked when data or physical goods move between points in the supply chain. Blockchain records are by their very nature transparent so activity can be tracked and analyzed by anyone authorized to connect to the network. This allows Verity to track and trace products using our IoT devices all over the world and store that data in one secure, transparent database.
Security is the largest concern for IoT devices while also being of the most revolutionary aspects of the blockchain. Imagine a scenario where hackers can infiltrate a supply chain using IoT to track and trace. They not only shut down the processes but also steal the data involved. If the data is exchanged over a blockchain network, the overall security of the IoT network is tremendously enhanced. The data is safe and secure behind the world’s most secure and trustworthy network.
Blockchains use smart contracts to enforce contractual obligations via the blockchain. Smart contracts get automatically executed when the conditions of the contract are fulfilled. Using smart contracts, actions can be executed across various entities in the supply chain automatically, in an immutable manner, and without disputes.
ARTIFICIAL INTELLIGENCE AND IOT
In the past, code was written and computers would perform whatever the software directed it to do, nothing more. Artificial intelligence allows the computer to go beyond what it is instructed to do and allows it to “learn” and operate independently. The algorithms actually improve with time. When combined with IoT networks, the computer recognizes meaningful patterns buried in mountains of data provided by the IoT devices, prioritizes it, and learns from the data.
IoT platforms are already using machine language, which is a subset of Artificial Intelligence. With full-fledged Artificial Intelligence, like Verity uses, IoT platforms would maximize their full potential to track and trace enormous amounts of data all over the world. To achieve the full benefit of IoT, the speed and accuracy of the analysis are crucial. The decisions made by IoT platforms would advance over time as the AI software learns with experience.
Predictive maintenance is an area of interest to many manufacturers. The endeavor is always to cut down on the downtime, and increase machine availability without increasing expenditure on maintenance. SK Innovation, a leading South Korean oil refiner, is using artificial intelligence to predict the failure of connected compressors. AI-based systems have helped save Google 40% on data center cooling costs by predicting the temperature and pressure thereby limiting the energy usage. All major IoT platforms like Azure IoT, AWS IoT, etc. now have machine learning for predictive capabilities already incorporated, but going forward the deep learning capabilities of artificial intelligence will advance IoT to become incredibly accurate and advanced.
IOT, BLOCKCHAIN & AI IN ACTION – PUTTING IT ALL TOGETHER
IoT, AI, and Blockchain can complement each other well and can potentially remove some of the drawbacks that each technology may experience independently. Artificial Intelligence gets layered over the IoT platform while the data from external sources flows through the Blockchain platform. Even the data exchange within the IoT network can happen on a blockchain to ensure the traceability and recording of all transactions. Multiple IoT networks can exchange data while the brilliance of Artificial Intelligence will exponentially enhance with the collection of more data. Verity has created an all-encompassing, scalable system that can authenticate, categorize, and monitor virtually any form of data to qualify and quantify all marketing, transactional or distribution claims of virtually any product. The need for this system is worldwide, and its importance is unparalleled. The union of these technologies will deliver increased efficiency, security, transparency, and legitimacy. In the not so distant future, these technologies will be a necessity in order to remain competitive.

Last time we have successfully connected to devices. Now we can try to send some commands.
ADB commands are a lot like HTTP requests.
- Each request has a url called “service string” to specify it’s type.
- Simpler requests embed parameters in “service string”, like GET requests.
- More complex requests send extra data to the stream before daemon responses, just like POST requests.
But actually ADB streams are fully duplex, client and daemon can send data to each other at any time.
Let me explain it in more detail.
