A novel method has been developed for the measurement of the activity coefficients of an amino acid and the mean ionic activity coefficients of an electrolyte in water-electrolyte-amino acid systems. The method uses an electrochemical cell with two ion selective electrodes and a…
The primary objective of this thesis is to provide accessible methods for numerical analysis of the mechanical behavior of welded structures specific to roadgoing trailers as defined by the Federal Motor Carrier Safety Administration. The area of highest interest is hot-dip galv…
High-temperature composite materials have broad applications in the energy and transportation sectors because of their unique capabilities to sustain strength at elevated temperatures, inert interaction with some coolants, and their high strength-to-weight ratio. These encompass…
The thesis investigates the dynamics of liquid cooling of the Three-Dimensional Integrated Circuit (3D-IC). Using 3D ICs is one of the most viable solutions for achieving high integration density of integrated circuits, without facing the unavoidable problems arising from shrink…
Electron Beam Melting (EBM) is an additive manufacturing process that presents a lower level of internal defects in comparison to Selective Laser Melting (SLM). Pairing Hot Isostatic Pressing (HIP) with Additive Manufactured metal parts, sub-surface voids can be eliminated throu…
The goal of this work is to advance a novel nondestructive testing (NDT) method for controlled, rapid, and effective inspection of a structure through the integration of microwave NDT and thermography, referred to as Active Microwave Thermography (AMT). In AMT, the structure und…
Since their discovery, tight oil and gas reservoirs have been plagued by low ultimate production numbers that rarely surpass 10%. One of the major factors contributing to this is the incomprehension of fluid phase behavior in these reservoirs. Indeed, operators only account for …
Zamanla enerjiye olan ihtiyacın artmasıyla bu ihtiyaçların karşılanması için fosil yakıtlar gibi çevreye zarar veren yakıtların kullanılması; insanları, çevre ile dost olan ve ihtiyaçları istenilen seviyede karşılayabilen enerji kaynakları arayışlarına yönlendirmiştir. Fosil yak…
Intriguing transport phenomena of phonons and photons in nanoporous structures have revolutionized the development of materials in recent decades. The particle- and wave-like transport of phonons have respectively demonstrated significant thermal conductivity reduction in thermo…
Amacı: Bu in vitro çalışmanın amacı, iki farklı monolitik zirkonya materyali ve bir zirkonya altyapı materyali kullanılarak üretilen tek üye kronların, termomekanik yaşlandırma sonrası kırılma direncini değerlendirmektir. Gereç ve yöntemler: 72 adet çekilmiş molar diş toplandı v…
In this dissertation, heat transfer and cooling mechanism of a cryogenic submerged pump motor, and cavitation behavior of a cryogenic pump are investigated. Cryogenic pumps for Liquefied Natural Gas (LNG) applications are unique in design with respect other industrial pump appli…
The distribution of liquid droplets emerging from an evaporator tube bundle is characterized for refrigerants R-123 and R-134a with a triangular and rotated triangular tube arrangement with a pitch of 1.167. The purpose of this research was to improve understanding of the drople…
Fused filament fabrication (FFF) based additive manufacturing (AM) of polymers and composites is a growing interest in processing tailorable parts with functional requirements like structural integrity, lightweight, high-temperature capability, etc. In general, the parts manufac…
This study focusses upon simulation of building blocks for silicon photonic integrated circuits. The two necessary steps for the simulation are control of temperature in the integrated Mach-Zehnder Interferometer (MZI) or modulators (MZM), and stabilization and tuning of optical…
Dallanma türü, şekli ve sayısına bağlı olarak farklı yapı mimarisi gösteren makromoleküllerin istatistiksel termodinamiği son zamanlarda önemli bir araştırma alanıdır. Bu konuda Simha-Somyscynky (SS), örgüdeki düzensizliğin bir ölçüsü olan boşlukları göz önüne alarak zincir mole…
Talaşlı imalat operasyonlarında kesici takım ile iş parçası arasında yüksek sıcaklıklar oluşarak, kesme işlemine olumsuz yönde etki etmektedir. Ortamda oluşan ısının talaş ile birlikte kesme noktasından uzaklaştırılması gerekmektedir. Geleneksel soğutma yöntemlerinden farklı ola…
This project examined the often competing perspectives of ludology and narratology in the field of video game studies, and attempts to incorporate both into a model of game narrative engagement based on the laws of thermodynamics. Further, this project sought to demonstrate that…
