Thermal Analysis of Cells Behavior in Modular Lithium Iron Phosphate Battery System in Urban Electric Bus Fleet

Energy Science &Engineering, EarlyView.
Real‐world analysis of lithium iron phosphate battery systems in electric buses shows minimal short‐term temperature impact on energy but significant long‐term degradation at higher temperatures. Efficient cooling and thermal uniformity are critical to prevent accelerated aging, maintain performance, and ensure safety under dynamic operating conditions.

Subordination of related party claims in insolvency: A suggestive framework for Asian regimes

International Insolvency Review, EarlyView.
Abstract Related party loans, due to their inherent nature, warrant a higher threshold for scrutiny when compared to loans extended by unrelated parties. Why were these monies advanced as loans, carrying higher priority in insolvency, rather than being invested as share capital?

Smart Sensor‐Integrated Lysimeter System for Affordable on‐Farm Crop Water Monitoring and Irrigation Management

Irrigation and Drainage, EarlyView.
ABSTRACT Accurate monitoring of crop water use is critical for precision irrigation, yet conventional lysimeter systems remain too costly and complex for widespread adoption. This study presents the development and field validation of a low‐cost, information and communication technology (ICT)‐enabled weighing lysimeter system that integrates load cells,

Mobile Worm-Like Robots for Pipe Inspection

, 2012
Worm-Like Robots (WLR) have a simple construction, and they do not need any special actuators such as wheels, caterpillars, or legs. Therefore, mobile vibration robots can move not only in space, but also in dense materials, which are not available for wheeled or leg-equipped robots.

Unmanned Aerial Systems for Corrosion Detection: Multi‐Sensor Technologies, Challenges, and Opportunities for Next‐Generation Inspection

Quality and Reliability Engineering International, EarlyView.
ABSTRACT Corrosion remains a critical threat to the integrity and service life of infrastructure in industries such as oil, gas, construction, renewable energy, and transportation. Traditional inspection methods, being labor‐intensive, hazardous, and often subjective, fall short in addressing modern inspection demands.
