Temperature

A wide variety of products are now made of metal alloys. The superior properties of these alloys permit products to be used in very demanding environments where other materials would fail. The major quality issues for these alloys are melt-related defects, such as segregation de…

This thesis focuses on energy considerations in the MOSFET when we supply a bias to it. We also notice that the length of the MOSFET gets smaller and smaller then for a small release or exchange of energy that may take place in a MOS transistor which can cause a change in the te…

Planar transistors have been the important building block of integrated circuits for decades, during which the size of transistors has steadily decreased. We will evaluate energy released due to recombination and also evaluate energy stored in the electric field for the step jun…

Micro heat pipe is a small-scale passive heat transfer device of very high thermal conductance that uses phase change and circulation of its working fluid to transfer thermal energy. Different from conventional heat pipe, a micro heat pipe does not contain any wick structure. In…

Scientists face an unprecedented challenge of increasing food production by 100% within the next fifty years to meet demand while responding to the undetermined effect and impact of climate change. To respond to these challenges, scientists are turning to models to assist them i…

In the recent past, there are indications of changes in the surface air temperature, extreme weather events, snow and Indian summer monsoon. This thesis analyses the above weather phenomena based on observed data and climate model simulations for the present as well as the near …

Decreasing power consumption in small devices such as handhelds, cell phones and high-performance processors is now one of the most critical design concerns. On-chip cache memories dominate the chip area in microprocessors and thus arises the need for power efficient cache memor…

An improved understanding of the thermo-hydro-mechanical behavior of unsaturated soils under elevated temperatures and high suction magnitudes is needed to interpret the behavior of thermally-active geotechnical systems where very dry conditions may be encountered. Examples of r…

In an effort to find a biological control agent of Bagrada hilaris, an invasive pentatomid pest on brassica crops in western North America, three hymenopteran egg parasitoids were recovered from brassica plant debris in Pakistan and sent to California, USA for evaluation. One of…

Vector-borne diseases (VBDs) present a considerable global health burden. Among VBDs, the mosquito vector transmits important pathogens that are responsible for causing disease in humans including dengue fever, Zika, Japanese encephalitis, West Nile fever, chikungunya fever, and…

Environmental temperatures are among the most significant factors affecting the ecology, behaviour, and evolution of organisms across all levels of biological organization. As such, understanding the impacts that natural thermal regimes have on organisms is central to the study …

Where fishes are found, and in what temporal patterns and under which physical conditions, are basic questions of biology and management. Salmonid species occupy distinct habitats across their life stages, usually reproduce only once, and are subject to intense anthropogenic pre…

Temperature was invented in the 17th century. While cosmologists affirm that fluctuations in heat are as old as the universe, the intensive quantified scale marking these fluctuations has a relatively short history. This dissertation analyzes why temperature developed when it di…

Onion is a vegetable crop that is consumed and cultivated worldwide. The production of bulbs, however, is threatened by pathogens and pests that infect onion plants and cause yield losses. Three severe diseases of onion are leaf blight, neck rot and white rot and all three are c…

The addition of a thermal energy storage (TES) into a process allows the operator to store and release thermal energy on demand. This increased process flexibility leads to potential benefits such as shifting energy demand from peak to off-peak hours. In particular, so called ph…

Warming climates have had various consequences on terrestrial and aquatic food webs that are expected to persist. There is evidence suggesting that certain organisms are better equipped to handle changing climates compared to others. Therefore, the purpose of my thesis was to st…

In this thesis, we investigate the scaling of the critical current density (Jc) and the pinning force (PF) in Y1− xGdxBa 2Cu3O7−δ high-Tc superconductors and La1.45Nd0.40Sr0.15CuO 4 stripe phase superconductor. The main objective is to study the effect of paramagnetic contributi…
