Using energy piles for geothermal heat exchange in buildings offers a sustainable alternative to traditional temperature regulators. However, designing these systems is often complex. Now, researchers from Shibaura Institute of Technology, Japan, have developed a simplified modeling framework to improve the design of energy pile systems. Using a combination of finite element modeling and field testing, they quantified the thermal interference between piles and soft clay soil—offering insights for quicker and enhanced geothermal performance.
A recent study by Associate Professor Takehisa Hirayama and Professor Osamu Kano from the Department of Neurology at Toho University School of Medicine has revealed a critical gap in the use of accessibility features among people living with Amyotrophic Lateral Sclerosis (ALS) and their caregivers. Though over 90% of ALS patients surveyed reported daily use of smartphones, tablets, or computers, many are unaware of the accessibility tools embedded in these devices—tools that could greatly enhance their quality of life as the disease progresses.
