Steam turbines are an integral part of power generating systems. The durability and reliability of steam turbines depend heavily on the integrity of their blades. In the last stages of a steam turbine, steam condenses and produces droplets. The effect of these droplets on the ef…
There is a significant interest in harnessing the available flexibility that exists on the demand side of the distribution energy systems by implementing energy storage or demand response programs. Appropriate choices regarding technical design parameters, involvement of flexibi…
This dissertation examines the effect of model-selection uncertainty in autoregressive models. The first chapter of the dissertation identifies the effects of model-selection uncertainty in autoregressive models—namely, the bias of the coefficient estimates, the bias of their st…
Two multi-brand models of consumer brand choice behavior have emerged and have been tested over the years and in a number of countries. The Brisoux-Laroche brand categorization model permits one to predict consumer brand choice by knowing the focal brand's location in a certain …
The main purpose of this research is to analyze the behavior of the Real Exchange Rate (RER) in 11 Arab countries over the period 1971–2001. A model based on the work of Edwards (1989) for RER fundamentals was investigated to determine the equilibrium level of the real exchange …
The problem. Historically, researchers could only agree that the optimal capital structure was the one that maximized the firm's wealth. Assuming that a common set of factors exists that can be combined to describe both the maximization of the firm's value (i.e., shareholder wea…
A periodic review (S, T) inventory control model for slow-moving spare parts for a single-echelon inventory control system is developed and evaluated using real data from a large manufacturer. Although forecasting-based models are quite realistic for inventory control of fast-mo…
The markedly different financial structures of firms in the developing and industrialized countries provide the motivation for this dissertation. What explains the financial structure choice of firms in developing countries? Many theories in Finance have been developed to explai…
In the last half century, there has been a remarkable expansion in the rate and scale of dam construction worldwide. Many of these dams have been successful in providing various economic benefits. However, reservoir sedimentation decreases useful capacity of dams, shortens their…
This thesis estimates a dynamic model of the Nigerian current account over the period 1970–1999 using the permanent income hypothesis as a guiding principle. Our model augments the classical consumption smoothing model, which relates the current account to changes in net output …
A study of adsorption equilibria of oxygen, nitrogen and oxygen-nitrogen mixtures on types 4A, 5A, 13X and Na-Mordenite molecular sieve pellets has been made. Pure component isotherms, using a volumetric apparatus, have been measured for each gas on each adsorbent at pressures u…
In decision making problems under uncertainty, Mean Variance Model (MVM) consistent with Expected Utility Theory (EUT) plays an important role in ranking preferences for various alternative options. Despite its wide use, this model is appropriate only when random variables repre…
This thesis explores the links between different ways of modelling the physical world. Finite difference numerical simulations may be used to encode the behaviour of physical systems, allowing us to gain insight into their workings and even to predict their behaviour. Similarly,…
Dynamically Coupled Socioeconomic system dynamics models integrated with physically-based Environmental Models (DCSEM) can aid in resolving complex environmental problems involving dynamic interactions between socioeconomic and biophysical systems. DCSEMs are promising tools for…
Bilgi teknolojisi departmanları günümüz bilgi ve teknoloji çağında kurumlar için hayati öneme sahip departmanlar olarak öne çıkmaktadır. Havacılık sektörü ise teknolojiyi en yüksek seviyeden kullanan ve teknolojik ilerlemeye katkıda bulunan sektörlerden biri olarak göze çarpmakt…
Enerji endüstrisi, ekonomik ve sosyal meslek perspektiflerinden, ürün, hizmet ve mal sağlayıcılarından en önemli alanlardan biridir. Bu endüstri, daha iyi yaşam koşullarının sağlanması için tüm insan faaliyetlerine önemli ölçüde katkıda bulunduğu için, nüfusun ve ulusal ekonomin…
It is a known fact that workforce is the most important resource for the companies operating in the service sector. Therefore; effective and efficient utilization, planning and directing of the workforce resource is one of the most essential requirements. For banks, a large numb…
Intraspecific competition is ubiquitous in nature and can fundamentally shape the individual life history. Competition occurs, and consequently influences life-history traits, through the direct effects of interference and indirect effects of exploitation. Importantly, it is the…
This dissertation presents an original investigation of several topics related to seismicanalysis and currently-implemented code-design procedures for seismically isolatedstructures, focusing primarily on high-damping rubber-based isolators.
