Plate heat exchangers are widely adopted in many industrial applications, such as ventilation, air conditioning, heat transfer processes, heat pumps and cooling of hydrodynamic circuits in engines. They provide higher heat transfer performance, compactness ...
With technological progress, humans tend to create engineering systems with constantly increasing complexity and higher operational requirements. Many complex systems require the use of a Health Management (HM) solution to ensure safety and enable lifecycl ...
We study the temperature-dependent phonon modes of the organometallic lead iodide perovskite CH3NH3PbI3 thin film across the terahertz (0.5-3 THz) and temperature (20-300 K) ranges. These modes are related to the vibration of the Pb-I bonds. We found that ...
Time lag and quantization in temperature sensors in enterprise servers lead to stability concerns on existing variable fan speed control schemes. Stability challenges become further aggravated when multiple local controllers are running together with the f ...
Rock scour occurring near dam foundations due to high-velocity jets of spillways impinging into the plunge pool is a major concern regarding dam safety. Scour in fractured rock resulting from high-velocity jet impact is a complex phenomenon, which involves ...
Background. The small characteristic sizes (in the range of 102 - 103 μm) of Microstructured reactors (MSR) lead to very high specific interfacial area which, in turn, increases heat- and mass transfer efficiency. However, for quasi instantaneous exothermi ...
Production in a controlled environment is becoming an increasingly important issue in various branches of industry. In the food, pharmaceutical, optical and semiconductor industries, today’s mass production would not be possible without so-called “cleanroo ...
In our research we use the technology of electrochromic (EC) glazing to maximize the use of daylight and minimize the energy consumption in buildings while preserving visual and thermal comfort of the users. We propose an advanced automatic control of EC w ...

In tropical and subtropical regions, air-conditioning is employed throughout the year, which poses a significant challenge to the designer in reducing its energy consumption. Buildings in these regions would have latent load that is large enough throughout ...
This study investigates the potential for energy and water sustainability in hot and humid climates by utilizing the condensate captured from large dedicated air handling units (AHUs) for pre-cooling outdoor air in another AHU and subsequently offsetting c ...
