Plc analog Tutorial
This document discusses analog inputs and outputs for programmable logic controllers (PLCs). It begins by introducing analog values as continuous rather than discrete, and how they must be converted to and from digital values using analog-to-digital (A/D) and digital-to-analog (D/A) converters. It then focuses on the principles of analog inputs, including sampling issues like aliasing and quantization error. Equations are provided to calculate values from A/D converters. The document also briefly discusses analog outputs and the relationships for D/A conversion.

2) The code configures the ADC ports and control registers, reads the conversion results when the ADC status indicates a conversion is complete, and prints the voltage levels to the UART.
3) The results show the ADC accurately converts analog voltages from 0-3.1V to their corresponding 10-bit digital values, which are printed to the UART terminal.
Ec8791 lpc2148 pwm
This document discusses pulse width modulation (PWM) and how it is implemented on the LPC2148 microcontroller. PWM is a technique for controlling the power delivered to a load by varying the duty cycle, or on-time, of a pulse signal while keeping frequency constant. The LPC2148 has a 32-bit timer/counter for PWM that can generate either single-edge or double-edge controlled PWM signals on multiple pins. It uses match registers to set the PWM period and pulse widths by controlling the rising and/or falling edges of the output pulses.
Part 5 PLC inputs & outputs
There are two main types of input/output modules for a PLC: analog and digital. Analog modules handle continuous signals like 0-10V, 4-20mA, and -20-20mA, while digital modules handle on/off signals represented as 1s and 0s. Common digital inputs include push buttons, switches, and sensors, while common digital outputs include relays, contactors, and lamps. Analog inputs include temperature and pressure sensors, and analog outputs control actuators, valves, and drives. The next video will discuss PLC programming languages.

Smart Energy and Power Analysis Through EKALYSIS
By EKALYSIS energy analysis is very easy. EVL-3 stores energy data on SD Card and disk capture save it to computer or laptop.
EKalysis helps to analyse this data by presenting it in Tabular and graphical format.
It also shows events information.
Reports are generated for every date you selected.
You can also save all Tabular data in csv and graph data in image file.
It is useful for analyzing energy of plant,industry, home.
It is also used for testing of load and power of various machines.
UPS,Servo Stabilizer, inverter, heavy machines are also some example which power can be tested by this software.
It is not only energy or power logger, its the step to know energy.
Gprs based meter and data logger
GPRS based meter and data logger measure your electricity data and log it on the server www.emdata.in .You can access this data any time anywhere.

"NATO Hackathon Winner: AI-Powered Drug Search", Taras Kloba
This is a session that details how PostgreSQL's features and Azure AI Services can be effectively used to significantly enhance the search functionality in any application.
In this session, we'll share insights on how we used PostgreSQL to facilitate precise searches across multiple fields in our mobile application. The techniques include using LIKE and ILIKE operators and integrating a trigram-based search to handle potential misspellings, thereby increasing the search accuracy.
We'll also discuss how the azure_ai extension on PostgreSQL databases in Azure and Azure AI Services were utilized to create vectors from user input, a feature beneficial when users wish to find specific items based on text prompts. While our application's case study involves a drug search, the techniques and principles shared in this session can be adapted to improve search functionality in a wide range of applications. Join us to learn how PostgreSQL and Azure AI can be harnessed to enhance your application's search capability.

The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.

Lee Barnes - Path to Becoming an Effective Test Automation Engineer.pdf
So… you want to become a Test Automation Engineer (or hire and develop one)? While there’s quite a bit of information available about important technical and tool skills to master, there’s not enough discussion around the path to becoming an effective Test Automation Engineer that knows how to add VALUE. In my experience this had led to a proliferation of engineers who are proficient with tools and building frameworks but have skill and knowledge gaps, especially in software testing, that reduce the value they deliver with test automation.
In this talk, Lee will share his lessons learned from over 30 years of working with, and mentoring, hundreds of Test Automation Engineers. Whether you’re looking to get started in test automation or just want to improve your trade, this talk will give you a solid foundation and roadmap for ensuring your test automation efforts continuously add value. This talk is equally valuable for both aspiring Test Automation Engineers and those managing them! All attendees will take away a set of key foundational knowledge and a high-level learning path for leveling up test automation skills and ensuring they add value to their organizations.

Direct losses from downtime in 1 minute = $5-$10 thousand dollars. Reputation is priceless.
As part of the talk, we will consider the architectural strategies necessary for the development of highly loaded fintech solutions. We will focus on using queues and streaming to efficiently work and manage large amounts of data in real-time and to minimize latency.
We will focus special attention on the architectural patterns used in the design of the fintech system, microservices and event-driven architecture, which ensure scalability, fault tolerance, and consistency of the entire system.
