The dynamics of physiological stress and thermal balance were investigated in men subjected to endogenous and exogenous heat loads. The study was conducted using the thermometric method. Substantial differences in the dynamics of the tested parameters and their quantitative characteristics were observed in 1 out of 8 participants. In this article, the observed differences are rationalized in te...

Thermal buckling loads of laminated composite plates are maximized for a given total thickness. Fiber directions and relative thickness of layers are considered as design variables. Analysis of buckling temperature is carried out by using the finite element method, while the imperialist competitive algorithm (ICA) is employed to optimize as many as seven variables for the different layered plat...

A new partitioning approach integrates the power devices and drive of a high-efficiency synchronous-rectified buck converter for numerous advantages in low-voltage power systems. This approach, coupled with a low-cost voltage-mode controller, improves efficiency by eliminating the dissipative current-sensing resistor and reduces size with a smaller inductor. The resulting converter responds fas...

In this study two commonly used steels in boiler plants, i.e. (SAE-213) T-22 and SA516 (Grade-70) were coated with different thermal spray processes namely HVOF and cold spray. The coating powder used was made up of NiCrTiCRe powder. The performance of the coated as well as uncoated material was investigated using a pin-on-disc machine [Model: Wear and Friction Monitor Tester TR-20], supplied b...

Seaports are progressively electrified to harness various energy resources provide green logistic services ships. They essentially act as multi-energy microgrids enhance the efficiency and environmental sustainability of maritime industry. This trend necessitates coordinated operation multiple sectors in seaport microgrids, which is a challenging problem due complex couplings power, thermal, fl...

A finite element solution based on equevalent elements is proposed for the static and dynamic analysis of tallhigh tensioned cable antennas. To reduce high number of degrees of freedom in space frame body of a structure, a simple equivalent beam element is defined for each simulative substructure. This numerical procedure is applicable to analyze complex three dimensional assemblies of substruc...

Poultry are exposed to a number of concurrent stressors during transportation. It is proposed that thermal challenges (both elevated thermal loads and cold stress) constitute the main threat to the birds’ welfare and survival. The effects of thermal stress may be exacerbated by extended withdrawal of food or water and by exposure to vibrations and accelerations. Existing pathologies and injurie...

The axial permanent magnet magnetic bearingless flywheel machine (APM-BFM) mostly operates under the state of high-power fast charging and discharging. Due to characteristics density per unit volume, centralized windings have small heat dissipation area high thermal loads, temperature rise on APM-BFM is a very important issue. Thermal analysis thus particular importance particularly for modern ...
