Thermal considerations play an increasingly important role in the design of new processors. Thermal concerns impact how chips are laid out, how quickly processors can be clocked, processor reliability, and how expensive the packaging is. Current production chips are often packaged to dissipate maximum typical power, rather than maximum absolute power. We investigate techniques which would allow...

In this research, thermal buckling of thin rectangular plate made of Functionally Graded Materials (FGMs) with linear varying thickness is considered. Material properties are assumed to be graded in the thickness direction according to a simple power law distribution in terms of the volume fractions of the constituents. The supporting condition of all edges of such a plate is simply supported. ...

Job scheduling in data centers can be considered from a cyber-physical point of view, as it affects the data center’s computing performance (i.e. the cyber aspect) and energy efficiency (the physical aspect). Driven by the growing needs to green contemporary data centers, this paper uses recent technological advances in data center virtualization and proposes cyber-physical, spatio-temporal (i....

The ability to predict the short-term behavior of ground loop heat exchangers (GLHE) is critical to the design and energy analysis of ground source heat pump (GSHP) systems. Thermal load profiles vary significantly from building to building – GLHE designs can be dominated by long-term heat build-up or short-term peak loads. In some extreme cases, where the GLHE design is dominated by short-term...

Abstract. Active and reactive power demands measured in Scottish Medium Voltage (MV) distribution networks are used in this paper to correlate variations in demands with the short-term and long-term variations of temperature. The methodology is illustrated on the example of the total network demands (sum of the demands at all monitored bulk load supply points), with the analysis presenting seve...

For the past several years, cryogenically cooled sensors have become an increasingly popular method of observation and study for both space-based and ground-based operations. Accordingly, various cooling techniques have been developed to accommodate this group of sensors. Because of rising performance standards and escalating cost limitations, cryocoolers have become an impressive cooling techn...

In the present article, buckling analysis of functionally graded annular thin and moderately thick plates under mechanical and thermal loads is investigated. The equilibrium and stability equations of the plate are obtained based on both classical and first order shear deformation plate theories. By using an analytical method, the coupled stability equations are converted to independent equatio...

The purpose of this paper is to estimate the fatigue life of an airplane wing with laminated composite skin, subjected to variable mechanical and thermal loads. To achieve this aim,at first, the three-dimensional model of airplane wing was drawn in CATIA software. Then, by transferring the model to the ABAQUS software, the finite element model of the wing wascreated. H...

This work deals with the three-dimensional magneto-thermo-elastic problem of a functionally graded truncated conical shell under non-uniform internal pressure and subjected to magnetic and thermal fields. The material properties are assumed to obey the power law form that depends on the thickness coordinate of the shell. The formulation of the problem begins with the derivation of fundamental r...

Surface integrity of workpieces after machining processes is one of the most essential requirements of engineers in advanced industries, since it has significant effect on performance and service life of the components. Based on this, thermal and mechanical loads generated by machining are responsible for change in mechanical properties of the machined workpiece and consequently, they should be...
