The aim of this study is to develop a sound transmission model that can be used to predict the vibration and noise levels of a submerged vessel. The noise transmitted from the mechanical vibrations of the hull of a submarine and the turbulent boundary layer excitation on the submarine are investigated. A simplified physical model of the submarine hull including the effects of bulkheads, end enclosures, ring stiffeners and fluid loading due to the interaction of the surrounding medium is presented in the study. An energy approach, i.e., Statistical Energy Analysis (SEA) is used for the analysis because the characterization of the hull of the structure can be done by a very large number of modes over the frequency range of interest and the deterministic analysis methods such as finite element and boundary element methods are limited to low frequency problems. The application consists of the determination of SEA subsystems and the parameters and the utilization of power balance equations to estimate the energy ratio levels of each subsystem to the directly excited subsystem. Through the implementation of SEA method, the sound pressure levels of the hull of the structure are obtained. In terms of military purposes, the sound levels of the submarine compartments are vital in the aspects of the preserving of submarine stealth.

The purpose of this thesis is to explore whether or not there exists a difference between the old and new migrants who moved to Istanbul, Ankara, Bursa, Izmir, Gaziantep, Erzurum and Sanliurfa provinces pre and post 1990, and the disadvantaged residents born in the urban areas of these provinces in terms of education, health and employment. To attain this aim, a theoretical framework, through which main features of the concept of disadvantageous were discussed.The overview of the literature, is based on these three dimensions of being disadvantaged, which are education, health and employment by using socio-economical characteristics as the interpretive tools. Therefore, the definition of disadvantageous centered on the notion of migration is accepted as a background of the study. In this respect, disadvantaged people are accepted as a group that experiences a higher risk of poverty and social exclusion than the general population.

This thesis attempts to stress the decisiveness of armed force for the capitalist hold of state power and that only if a multi-level analytical framework is adopted a fuller account of the reality can be given with reference to the capitalist hold of state power. After laying the methodological and theoretical grounds for a multi-level analysis along with the privilege of armed force as the factor enabling the state power, it concretizes the multi-level analytical framework in the context of Turkey. It drives the attention to the co-existence of micro and macro level factors influential over state practices. The mafia forces are also proposed to be integrated to the analysis of the capitalist state on account of the considerable economic and armed means they hold. The Weberian approach describing the state in terms of its monopoly of legitimate use of force is proposed to be replaced by an alternative one not holding the consent of the inhabitants as an unconditional necessity for the presence of the state. The class struggle process is held to take place at a site embracing the interplay of associative and communal relationships in a micro-macro range. The routes of tendential multiplicity and totality are attempted to be explored at least partially. Also the importance of strategy and tactics are stressed and some threats waiting the forces longing for a world without exploitation and domination are underlined.

This thesis study is focused on experimentally investigating pump noise at design and off-design operations and its relations with pressure fluctuations. Small size pumps are placed in a semi-anechoic chamber and operated at various system conditions and various rotational pump speeds. Pump operational data, noise data and time dependent pressure data are recorded. Fast Fourier Transform spectra of noise and pressure data are compared. Coherence spectrum between sound pressure level and hydraulic pressures are obtained. Data processing, Fast Fourier Transform and cross correlation are conducted with specific software Soundbook SAMURAI. The experiments have indicated that system characteristics or pump size do not have any influence on the noise of pump. On the other hand, pump characteristics are found to be distinguishable by means of peak frequencies on the sound spectra which are proportional to blade passing frequency. Results of cross correlations also show that, pump outlet pressure is a more significant source of noise than pump inlet pressure.

Housing price studies is the first step of housing market analysis. Prices are determined at the intersection point of supply and demand curves, which determine equilibrium point that represents equilibrium price and quantity level. At a point in time demand factors are more important in determining the prices because short-run supply curve is almost vertical. However, in the long run supply of housing, and its certain attributes, will increase if price premium arises in the previous periods. In most of the studies, house prices are analyzed by using hedonic price index technique, which enables us to have information about the demand side of housing sector. In the hedonic price framework, heterogeneous goods are considered as aggregations of characteristics, and implicit marginal prices for these characteristics are calculated. When &lsquo / Hedonic Price Analysis&rsquo / is applied to the housing sector, it shows us the price of each housing attribute and gives information about the preferences and willingness to pay of the people for each attribute. Therefore, at the end of such an analysis it is possible to see which attributes are valued most by house buyers in the city. The aim of this thesis is to reveal the implicit prices of housing attributes in the housing market of Ankara, for the year 2006, with the purpose of gaining more information about the demand side of the housing sector. For this purpose, hedonic pricing method is used with the data that are extracted from appraisal reports which include information about main attributes and estimated price of each dwelling unit.

The thesis builds up on the significance of the social aspect of the statistics giving direct reference to the standards of the European Union (EU) on statistics. The study concentrates on the modernization, reformation and transformation process of the Turkish Statistical System, particularly the health statistics on the basis of a specific Programme called &ldquo / Upgrading the Statistical System of Turkey&rdquo / funded by the EU and the Law on Turkish Statistics (No: 5429) within the process of the harmonization of the Turkish Statistical System, which aims the integration of the current system to the international one via the EU acquis communautaire. This thesis presents the causes of the death statistics as one of the most significant dimensions of statistics since it is the most extensive and the oldest public health surveillance system in the world. The reformation in the certification process, the classification stage and the analysis of the cause of the death statistics (COD) are examined in detail hereby. Improvement of the coverage, introduction of the International Classification of Diseases-10th Revision (ICD-10), development of institutional coordination and a new formation of the causes of death statistics in line with the EU requirements are analyzed in depth. Based on the findings of this study, it is proposed that the introduction of ICD-10 and improvement of the coverage of the COD statistics are not sufficient to ameliorate the shortcomings of the current death certificate system rested upon on the two documents including the &ldquo / COD forms&rdquo / and the &ldquo / burial licence&rdquo / in Turkey. The study also suggests that solutions to be proposed should be radical and effective since the problems encountered in the death certificate system are deep-rooted. Consequently, with regard to the issues of increasing the coverage of physical autopsy and providing training for the COD forms and with the aim of reducing diversified and complex chain of bureaucratic transactions, it is essential to bring an encompassing new legal base for the current death certificate system.

In this study in order to simulate the acoustic waves, Ray Theory and Normal Mode models are used. These methods are analyzed using MATLAB simulation tool / differences between two models are examined and a region with a known bottom profile and sound velocity profiles is investigated. The Ray Theory is used in acoustic systems which is the one of the applications of wave modeling. Ray theory is solved with standard Ordinary Differential Equation solvers and normal mode with finite element method. Different bottom profiles and sound velocity profiles previously taken are interpolated to form an environment and examined in the case study. in the case study.

Two sample statistical energy analysis (SEA) models are generated for a section of the fuselage panel of an aircraft, namely the uniform panel model which includes the frames and stringers, and the ribbed panel model in which the frames and stringers are smeared into the skin. Turbulent boundary layer (TBL) excitation is used as the primary acoustic excitation source. Stress levels are estimated from the average velocity data of the panels. The stress results are found comply with those obtained by the AGARD method. Effect of radiation from panels to exterior and interior of the sample skin panel as well as the pressurization of the skin panels are investigated separately to analyze their effects on the stress levels. The method is then used in the analysis of center fuselage skin panels on a basic training aircraft. Two models are generated for the aircraft analysis, namely the complete aircraft model and the simplified model which excludes the wings and the empennage. In addition to TBL, propeller noise is used as the primary acoustic excitation source. The effects of the wings and the empennage on the stress levels in the center fuselage skin panels are also investigated along with the radiation from panels to the exterior and interior of the aircraft and pressurization of the pilot cabin.

This thesis analyzes the pass-through of external factors into consumer and producer prices in Turkey, with a special emphasis on import price pass-through. To this end, pricing along a distribution chain framework is utilized and it is estimated by Vector Auto Regression (VAR) in a sample period of April 2002 to March 2009. Results show that the pass-through of external shocks into producer prices is higher than it is for consumer prices. Compared with the results of previous studies, findings point out that the degree of pass-through has declined recently in Turkey. In addition, it is found that external factors had significant contribution to annual consumer inflation between 2006 and 2008. Nevertheless, even the contributions of external shocks are excluded, year-end inflation targets would not have been attained.

In this thesis, localization of the underwater sound sources using matched field processing technique is considered. Localization of the underwater sound sources is one of the most important problems encountered in underwater acoustics and signal processing. Many techniques were developed to localize sources in range, depth and bearing angle. However, most of these techniques do not consider or only slightly takes into account the environmental factors that dramatically effect the propagation of underwater sound. Matched field processing has been developed as a technique that fully considers the environmental factors. Matched field processing has proven to be successful in many applications such as localization of sources in range and depth, the determination of environmental parameters, and the evaluation of model accuracies. In this study, first a comparative analysis of narrowband matched field processors is given. Namely four main processors: Bartlett processor, Minimum Variance Distortionless Response (MVDR) processor, MVDR with neighboring location constraints and MVDR with environmental perturbation constraints are compared in terms of their probability of correct localization under certain environmental conditions. Secondly, a performance assesment for the most common broadband matched field processors is made. The correct localization performances for incoherent broadband matched field processor, Tolstoy/Michalopoulo&#039 / s coherent matched field processor and broadband matched field processor with environmental perturbation constraints is given for certain environmental conditions. Finally, a new weighting approach to combine data for broadband matched field processing is introduced. The fact that information from different frequencies may have different reliability depending on the environmental conditions is considered to develop a weighting scheme. It is shown that a performance gain compared to existing processors can be achieved by using the weighting scheme introduced in this study.
