TEST RIG FOR HYDRAULIC FLUID (A3987) - NEOMETRIX DEFENCE
PROJECT: TEST RIG FOR HYDRAULIC FLUID (A3987)
The test rig is used to test the anti-wear properties and the aging
behaviour of hydraulic fluids under defined and reproducible
conditions. For this purpose, a vane pump Vickers 35VQ25A-11*20
for ASTM D6973-2014 and a Bent Axis type axial piston pump
A2F10 for JCMAS P 045 are used as test objects. The subsequent
investigation of the wear inserts and oil condition then allows
conclusions about the performance of the tested fluids, especially
their ability to avoid wear and resist oxidation. The modern and
ergonomically designed test rig meets all the specifications of the
European Machinery Directive 2006/42/EG to a high standard or
equivalent Indian Standard. The test rig is used to determine the
wear characteristics and oxidation/ aging of non-petroleum and
petroleum hydraulic fluids. For this purpose, a rotary vane pump
generates a test pressure under specific boundary conditions. The
result obtained is the total mass loss from the cam ring and the ten
vanes (ASTM D6973-2014) after the test. For indicating oxidation
stability or aging behaviour of hydraulic fluids this test bench, uses a
bent axis pump A2FO10 and a pressure relief valve DBDS 10
K1X/400V as load at high temperatures. The test takes place under
the influence of air and a copper catalyst. This procedure allows for
an accelerated aging rate using a real hydraulic component. The test
rig parameters meet the specifications according to ASTM D6973-
2014 and JCMAS P 045. Additionally, it is capable of carrying out the
evaluation of hydraulic fluid for frictional characteristics and energy
efficiency performance under indigenously developed and
industrially simulated test methods by varying load, speed,
temperature, pressure, flow rate etc.

Advanced control scheme of doubly fed induction generator for wind turbine us...
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

The study presented in this article shows the design of EHD thrusters and power supply for ion propulsion drones along with performance optimization of high-voltage power supply for endurance in earth’s atmosphere.
Embedded machine learning-based road conditions and driving behavior monitoring
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.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

Optimizing Gradle Builds - Gradle DPE Tour Berlin 2024
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.
