Abstract As the society is technologically advancing, there an increasing demand for advancements in computers. Therefore, computers will be replacing more human jobs future which force to work frequently. This foreshadows that may encounter problems such as overheating problem they are operating. Overheating indeed a researched because it cause serious damages computer overall, shortening its ...
Abstract The photoelectric properties of LED are affected by driving current and ambient temperature. To solve the problem light wane caused excessive overheating, LLC resonant converter with soft switching was chosen as main topology, improving power efficiency, reducing heat driver. Firstly, soft-switching conditions analyzed, constraint equation is obtained. Then, an improved particle swarm ...
The present paper shows the application of a three-dimensional coupled electrical, thermal, mechanical finite element macro-scale modeling framework of Spark Plasma Sintering (SPS) to an actual problem of SPS tooling overheating, encountered during SPS experimentation. The overheating phenomenon is analyzed by varying the geometry of the tooling that exhibits the problem, namely by modeling var...
Quantifying urban heat island effect often requires the observation of air temperature distribution over the whole city. Satellite or aircraft mounted radiometers, car mounted temperature sensors and GPS loggers or fixed point monitoring have been employed in previous studies for urban heat island effect analysis. Above methods often are very expensive, labour intensive and have its own limitat...
A major problems in the operation of laptop computers is overheating since it can affect the performance and stability, sometimes leading to system crash and hardware fatality. The objective of this work was to study the thermal behavior inside a laptop computer and to test the effectiveness of aproposed cooling method to overcome overheating problem. The proposed cooling system contained a the...
The effect of increasing the humidity in incubators was examined in 62 infants of less than 30 weeks' gestation. Thirty three infants nursed in high humidity for two weeks were compared retrospectively with 29 infants from an earlier study who were nursed under plastic bubble blankets or with topical paraffin but without raised humidity. Humidification reduced skin water loss and improved maint...
OBJECTIVES In this study we evaluated heat generation during the low-speed drilling procedure without irrigation. MATERIALS AND METHODS Ten artificial bone blocks that were similar to human D1 bone were used in this study. The baseline temperature was 37.0℃. We drilled into 5 artificial bone blocks 60 times at the speed of 50 rpm without irrigation. As a control group, we drilled into an addi...
