In recent years, vibration-based energy harvesting technologies have gained great importance because of reduced power requirement of small electronic components. External power source and maintenance requirement can be minimized by employment of mechanical vibration energy harvesters. Power sources that harvest energy from the environment have the main advantages of high safety, long shell life and low cost compared to chemical batteries. Electromagnetic, electrostatic and piezoelectric transduction mechanisms are the three main energy harvesting methods. In this thesis, it is aimed to apply the piezoelectric elements technology to develop means for energy storage in munitions launch. The practical problems encountered in the design of piezoelectric energy harvesters are investigated. The applicability of energy harvesting to high power needs are studied. The experience compiled in the study is to be exploited in designing piezoelectric energy harvesters for munitions applications. Piezoelectric energy harvesters for harmonic and mechanical shock loading conditions with different types of piezoelectric materials are designed and tested. The test results are compared with both responses from analytical models generated in MATLAB® and ORCAD PSPICE®, and finite element method models generated in ATILA®. Optimum energy storage methods are considered.

Electrothermal Analysis of the Field-Plated AIGaN/GaN HEMTs with SiO2 Passivation
Kara, Dogacan; AKGÜN, FATMA NAZLI DÖNMEZER (2017-09-01)
AlGaN/GaN high electron mobility transistors (HEMTs) are widely used in high frequency and power applications of the space and military industries due to their high RF power densities. When operated in full capacity, reliability of GaN HEMTs drop significantly due to device degradation, electron collapse phenomena, and concentrated heating effects. Although significant research has been done to investigate the effects of passivation, field-plates on the device degradation and the electron collapse separatel...
Developing a proactive conservation approach for an uncomfortable industrial heritage: Adana slaughter house (Kanara)
Ekici, Simay Cansu; Bilgin Altınöz, Ayşe Güliz; Conservation of Cultural Heritage in Department of Architecture (2019)
Major improvements in production technology led to the creation of new zones including various types of spaces where energy is generated, transmitted and used. With these developments, industrialization caused changes in the physical, natural and social environment. In this process, architecture and city planning were used as tools to create spaces for industry and at the same time contributing to the modernization of society. These complexes and buildings became the subject of conservation because they emb...
CHARACTERIZATION OF SPECIFIC HEAT AND MECHANICAL PROPERTIES FOR GRANULAR HEAT STORAGE MATERIALS
Baker, Derek Keıth; Johnson, Evan Fair(2018-12-31)
The GUNAM-ODAK research group is developing Thermal Energy Storage (TES) technologies for Concentrated Solar Power systems. Focus is on solid-particle (granular) TES materials such as silica sand due to their high melting temperatures and low costs. In the proposed work, the experimental equipment needed to characterize some of the most important properties of TES materials will be constructed, with the goal of characterizing new materials and providing accurate inputs for numerical modeling. Specifically, ...
Analytical Modelling, Simulation and Comparative Study of Multi-Junction Solar Cells Efficiency
Hadjdida, Abdelkader; Bourahla, Mohamed; Ertan, Hulusi Bülent; Bekhti, Mohamed (2018-12-01)
Currently, solar energy is promising the primary source of renewable energy that has a great potential to generate power for an extremely low operating cost when compared to already existing power generation technologies. Increasing the efficiency of solar cells is a major goal and the prominent factor in photovoltaic system research. Current triple junction solar cells reach 30% and the next generation will bring 35% in 5 years to peak at 40%. These cells are used in space environment and in terrestrial sy...
Comminution: Technology, Energy Efficiency and Innovation
Klein, B.; Altun, Naci Emre; Scoble, M. J. (2015-04-17)
With pressures to improve energy efficiency in mining, reducing energy usage in comminution has become the focus of innovation. Several advances have been made however the uptake of innovations and technologies is slow. A Technology Readiness Level guide has been developed for other industries that may be a useful tool for the mining industry. Examination of selected successful energy efficient technologies provides some insights and lessons that may provide direction for advancing new technologies. This pa...
