Abstract: In this paper, we are using PLC programmes to control the crane movement. The application of PLC could simplify circuits and make the design easier, safer and more reliable. Earlier in Industry, relays and contactors are adopted to control the crane motion in desired directions. Starting of the cranes and speed control of the crane is realized through convectional starters and resistance series. This kind of design has low reliability, complex operation, high electrical failure rate, power waste and low efficiency .These problems can be rectified by using programmable logic controller.

Design and development of programmable controller for air sampling machineeSAT Journals
Abstract A programmable Controller is designed and developed for time pedestal controlling of Air Sampling Machine. The major purpose of the designed system is to reduce filter damage of Air Sampling Machine. The main function of the controller is to automatically switching the Air Sampling Machine with predefined On-Off time interval for 24 hours operation. This is a low cost system which is designed using locally available components and user friendly. The controlling operation is maintained by ATMEL AT89C52 microcontroller. A programmable real time clock PCF8583 is used to produce timing control signal for automatic switching of the Air Sampling Machine. Control signals generated by real time clock operate opto-isolator and an electromechanical relay for switching the Air Sampling Machine. EEPROM (M24C64) is used to store necessary data. The instruction firmware for the designed controller has been developed in BASIC platform using BASCOM-8051 software. The designed system is functioning properly and serving the purpose of the design. Keywords: Programmable Controller, AT89C52 microcontroller, RTC, EEPROM, I2C Protocol, BASCOM-8051 IDE
Design and control of steam flow in cement production process using neural ne...Mustefa Jibril
In this paper a NARMA L2, model reference and neural network predictive controller is utilized in order to control the output flow rate of the steam in furnace by controlling the steam flow valve. The steam flow control system is basically a feedback control system which is mostly used in cement production industries. The design of the system with the proposed controllers is done with Matlab/Simulink toolbox. The system is designed for the actual steam flow output to track the desired steam that is given to the system as input for two desired steam input signals (step and sine wave). In order to analyze the performance of the system, comparison of the proposed controllers is done by simulating the system for the two reference signals for the system with and without sensor noise disturbance. Finally the comparison results prove the effectiveness of the presented process control system with model reference controller.
Induction motor is rotating type of electro-mechanical device. Induction motor convert electrical energy into mechanical energy. Induction motor is highly reliable, require less maintenance and have high efficiency. Induction motor are wide in range of operation and it used in many application because its construction is simple and robust. In past induction motor can be protected by manual operation of component such as timer, contactor, electromagnetic switch, voltage and current transformer. Protection of an induction motor against problem such as short circuit, temperature rise, single phasing and motor vibration occurring in the operation is very important. Manual operation of protection system are very slow and is not accurate. Looking to this issues, in this paper PLC based protection method is used. Which operated automatically, provide higher accuracy and quick response.
PID (Proportional Integral Derivative) is a control algorithm that mostly used in industry. However, users have never known what the PID model that used inside the PLC. By knowing the PID model that used in PLC, users will have more choice in determining the more appropriate tuning algorithm. Also, users can use MATLAB to perform analysis and can implement it to PLC. Through OPC Server (Object Linking and Embedding for Process Control Server) as a software interface, programs on a windows operating system can communicate with industry devices universally. PID model prediction method is done by comparing the output of the plant controlled by PID model in PLC and PID model in SIMULINK MATLAB using OPC Server intermediaries. Based on comparison result in graph and analysis using integral error method, PLC M221 using Parallel PID model and PLC S7-1200 using Ideal PID model.

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Assuming that there are two controls P1 and P2. P1 and P2 are synchronize
using the same timer. When one side signal port is on it will starts timer. Two
traffic controls are synchronize for every 30 seconds.
When one control starts its working, it will starts timer and display red light
till timer reaches to 20 seconds. From 20 to 30 seconds it will display yellow
light. At the same time another control will display green light.
When first control P1 reaches to timer value 30 seconds, it will stop timer. At
the same time second control P2 will starts timer. It will follow the same
