This document provides an environmental product declaration for several types of electromechanical actuators produced by Siemens. It includes information on typical energy consumption, materials used, weight, waste treatment, and certifications. The actuators are designed to reduce energy usage through automatic shutoff in the end positions and comply with RoHS restrictions. The document states that the actuators should not be disposed of with standard waste and must be properly recycled or treated as electronic waste according to local laws.
CG Power Systems Belgium, a leading supplier of on- and offshore wind turbine transformers and power solutions, is using OWI-Lab's large climate chamber on a frequently basis to test and validate their products under extreme climatic conditions. Hot climate and cold start-up tests with full electrical capacity are performed on a 'time sharing' basis in the laboratory. This means CG Power Systems rents the needed test infrastructure and their own engineers perform the testing.
The large testing space makes it possible for CG Power Systems to tests and validate multiple systems in one time at the same testing conditions. Simultaneous testing can be interesting for example to benchmark results of changes in the design with different product versions of machinery in the same climatic conditions.

This report details fan performance and efficiency measurements taken at Forbes Coal Dundee mine. Key metrics recorded include air quantity, pressure, power and efficiency for the mine's fans. The report requires review and sign off from personnel across safety, engineering and management functions.
Vortex generators were installed on over 500 turbines in 2014 to study their effects on reliability and performance. Trials showed that VGs provided production gains compared to unmodified turbines, though the gains were small and validation is challenging. VGs were found to positively impact airflow attachment along turbine blades to reduce stall effects. Testing also indicated that VGs may impact wind sensor readings on nacelles.
This document summarizes radiation shielding modeling done for critical fuel injection components in the LIFE fusion energy project. Monte Carlo simulations were used to model radiation transport from fusion targets and evaluate heating and damage to injection system materials from neutrons and photons. Results showed that a boron carbide shutter was effective at shielding and a minimum of 1 meter of concrete flooring could reduce radiation effects by 3 orders of magnitude, enabling component lifetimes of several years. Further modeling refinements and design optimizations were recommended to improve shielding.
Assessment of for Suitability of Ductile Iron Castings for cold climatesAbdullah Ansari
This document summarizes a technical feasibility assessment of using EN-GJS-400-18-LT castings for cold climate applications. Impact testing was conducted on 85 castings at various temperatures, and regression analysis showed that impact value is most significantly predicted by testing temperature and proof strength. Factor analysis identified testing temperature as the main effect. Of 80 castings tested at -20C, the analysis estimated that 6 would meet an impact requirement of 10J average at -40C, while 71 would meet 7J individual. It was concluded that 7J individual at -40C is very possible for EN-GJS-400-18-LT, but 10J average would require using EN-GJS-350-22-

This document summarizes an undergraduate research project using thermochromic liquid crystal (TLC) technology to measure air temperature changes in a blowdown wind tunnel. The student designed TLC-coated filaments, calibrated their color changes to temperature in a vacuum oven, and measured the filaments' reaction time. Results showed a clear relationship between temperature and hue, with a reaction time of 1.49 seconds for heating and 3.68 seconds for cooling. Future work could improve the calibration and test the filaments in the wind tunnel.

Harnessing WebAssembly for Real-time Stateless Streaming PipelinesChristina Lin
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.
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.

Low power architecture of logic gates using adiabatic techniquesnooriasukmaningtyas
The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.
