This document describes the Salp Swarm Algorithm (SSA), a recently developed swarm intelligence algorithm inspired by the behavior of salp swarms. SSA mimics how salp chains are organized with a leader salp and follower salps. The algorithm models the position updating of leader and follower salps to balance exploration and exploitation in problem solving. Key steps of the SSA include initializing salp positions, updating the leader's position towards food sources, and having followers update their position based on the leader using equations modeling motion.
Ant Colony Optimization (ACO) is a heuristic optimization technique inspired by the behavior of real ant colonies. It is used to find solutions to optimization and shortest path problems. The technique works by simulating ants walking between points, such as between their nest and food sources. As artificial ants walk, they lay down and follow pheromone trails. Over time, the shortest paths become more desirable as they have the most pheromone accumulated on them. The algorithm iteratively improves the solutions found via the probabilistic decisions of many agents (the artificial ants) based on local information and global pheromone trails.
The document discusses ant colony optimization (ACO), which is a metaheuristic algorithm inspired by the behavior of real ant colonies. It describes how real ants deposit pheromone trails to communicate indirectly and find the shortest path between their colony and food sources. The algorithm works by "artificial ants" probabilistically building solutions to optimization problems and adjusting pheromone levels based on solution quality, similar to how real ants reinforce shorter paths. It provides examples of how ACO has been applied to problems like the traveling salesman problem and discusses some extensions to the basic ACO algorithm.
Swarm intelligence is a modern artificial intelligence discipline that is concerned with the design of multiagent systems with applications, e.g., in optimization and in robotics. The design paradigm for these systems is fundamentally different from more traditional approaches.

Passerine swarm optimization algorithm for solving optimal reactive power dis...IJAAS Team
This paper presents Passerine Swarm Optimization Algorithm (PSOA) for solving optimal reactive power dispatch problem. This algorithm is based on behaviour of social communications of Passerine bird. Basically, Passerine bird has three common behaviours: search behaviour, adherence behaviour and expedition behaviour. Through the shared communications Passerine bird will search for the food and also run away from hunters. By using the Passerine bird communications and behaviour, five basic rules have been created in the PSOA approach to solve the optimal reactive power dispatch problem. Key aspect is to reduce the real power loss and also to keep the variables within the limits. Proposed Passerine Swarm Optimization Algorithm (PSOA) has been tested in standard IEEE 30 bus test system and simulations results reveal about the better performance of the proposed algorithm in reducing the real power loss and enhancing the static voltage stability margin.
The Autonomous Robotic Cleaner is an entry level mobile robot learning platform. It contains three channel IR collision sensor and a dual motor driver. Any arduino compatible platform can be used as the controller. The Arduino program transmits data every second to the computer then waits for a character from the Computer, when a correct character is received, then it tells the motors what to do.
In fact, most of us usually using a hand controlled vacuum for cleaning. From time to time technology come up and need to upgrade for easier human task. In addition, most of the people are working and they did not have enough time to clean. Moreover, most of vacuum robots in the market are expensive and may be large in size. So it is difficult to clean anywhere like under beds. Therefore, this project is built to be one of the advantages for human to clean the floor within small period and more effective.

This document analyzes transistor sizing and folding techniques to mitigate soft errors caused by radiation. It begins with an introduction to single event effects caused by radiation sources like cosmic rays. It then examines a 3D NMOSFET device and different ion profiles including alpha particles, copper and krypton. It evaluates increasing transistor widths to increase the critical charge of nodes using electric-level simulations. However, this does not capture the effect of increased device geometry on ion interactions. Therefore, device-level simulations are conducted showing collected charge increases with symmetric transistor sizing but peak pulse worsens. Further symmetric sizing simulations are recommended to see if recovery occurs.

Balancing a Segway robot using LQR controller based on genetic and bacteria f...TELKOMNIKA JOURNAL
A two-wheeled single seat Segway robot is a special kind of wheeled mobile robot, using it as a human transporter system needs applying a robust control system to overcome its inherent unstable problem. The mathematical model of the system dynamics is derived and then state space formulation for the system is presented to enable design state feedback controller scheme. In this research, an optimal control system based on linear quadratic regulator (LQR) technique is proposed to stabilize the mobile robot. The LQR controller is designed to control the position and yaw rotation of the two-wheeled vehicle. The proposed balancing robot system is validated by simulating the LQR using Matlab software. Two tuning methods, genetic algorithm (GA) and bacteria foraging optimization algorithm (BFOA) are used to obtain optimal values for controller parameters. A comparison between the performance of both controllers GA-LQR and BFO-LQR is achieved based on the standard control criteria which includes rise time, maximum overshoot, settling time and control input of the system. Simulation results suggest that the BFOA-LQR controller can be adopted to balance the Segway robot with minimal overshoot and oscillation frequency.

A Cooperative Coevolutionary Approach to Maximise Surveillance Coverage of UA...Daniel H. Stolfi
This paper presents the parameterisation and optimisation of the CACOC (Chaotic Ant Colony Optimisation for Coverage) mobility model used by an Unmanned Aerial Vehicle (UAV) swarm to perform surveillance tasks. CACOC uses chaotic solutions of a dynamical system and pheromones for optimising area coverage. Consequently, several parameters of CACOC are to be optimised with the aim of improving its coverage performance. We propose a Genetic Algorithm (GA) and two Cooperative Coevolutionary Genetic Algorithms (CCGA) to tackle this problem. After testing our proposals on four case studies we performed a comparative analysis to conclude that the cooperative approaches allow a better exploration of the search space by optimising each UAV parameters independently.

This document describes a firefighting robotic vehicle that can detect and extinguish fires autonomously. The robotic vehicle is equipped with sensors like a temperature sensor and smoke detector to detect fires. It also has a water tank and pump to extinguish fires. An Android application allows for remote control of the robot to move forward, backward, left, right and activate the water pump.

Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Optimizing Gradle Builds - Gradle DPE Tour Berlin 2024Sinan KOZAK
Sinan from the Delivery Hero mobile infrastructure engineering team shares a deep dive into performance acceleration with Gradle build cache optimizations. Sinan shares their journey into solving complex build-cache problems that affect Gradle builds. By understanding the challenges and solutions found in our journey, we aim to demonstrate the possibilities for faster builds. The case study reveals how overlapping outputs and cache misconfigurations led to significant increases in build times, especially as the project scaled up with numerous modules using Paparazzi tests. The journey from diagnosing to defeating cache issues offers invaluable lessons on maintaining cache integrity without sacrificing functionality.

Use PyCharm for remote debugging of WSL on a Windo cf5c162d672e4e58b4dde5d797...shadow0702a
This document serves as a comprehensive step-by-step guide on how to effectively use PyCharm for remote debugging of the Windows Subsystem for Linux (WSL) on a local Windows machine. It meticulously outlines several critical steps in the process, starting with the crucial task of enabling permissions, followed by the installation and configuration of WSL.
The guide then proceeds to explain how to set up the SSH service within the WSL environment, an integral part of the process. Alongside this, it also provides detailed instructions on how to modify the inbound rules of the Windows firewall to facilitate the process, ensuring that there are no connectivity issues that could potentially hinder the debugging process.
The document further emphasizes on the importance of checking the connection between the Windows and WSL environments, providing instructions on how to ensure that the connection is optimal and ready for remote debugging.
It also offers an in-depth guide on how to configure the WSL interpreter and files within the PyCharm environment. This is essential for ensuring that the debugging process is set up correctly and that the program can be run effectively within the WSL terminal.
Additionally, the document provides guidance on how to set up breakpoints for debugging, a fundamental aspect of the debugging process which allows the developer to stop the execution of their code at certain points and inspect their program at those stages.
Finally, the document concludes by providing a link to a reference blog. This blog offers additional information and guidance on configuring the remote Python interpreter in PyCharm, providing the reader with a well-rounded understanding of the process.
The CBC machine is a common diagnostic tool used by doctors to measure a patient's red blood cell count, white blood cell count and platelet count. The machine uses a small sample of the patient's blood, which is then placed into special tubes and analyzed. The results of the analysis are then displayed on a screen for the doctor to review. The CBC machine is an important tool for diagnosing various conditions, such as anemia, infection and leukemia. It can also help to monitor a patient's response to treatment.
