This study investigates and identifies the factors that affect mistrust and uncertainty when Korean industrial multinational enterprises (MNEs) generate new ideas in the front-end phase of new product development (NPD) processes. Specifically, this study focuses on the process of applying research data to support the generation and development of new products. Current research indicates that many companies frequently experience difficulties in this regard. This study comprises a large body of empirical study-centred research. It collates multiple interviews with research-based teams (consisting of planners as well as marketers and lifestyle researchers) and practice-based teams (i.e. designers and engineers) of leading multinational companies in the smart electronics and automobile industries. A primary outcome of the research is the specification of key constructs relating to mistrust and uncertainty during the application of research data in the process of selecting new ideas within the front-end of the NPD process, which appear to be linked to three factors: (i) a lack of common language (perspectives and approaches related to data and information when obtaining insights) between diverse expertise groups, (ii) a lack of appropriate communication channels between different functional groups, and (iii) a lack of productive tactics in using internal information. This research aims to enrich NPD studies by presenting the validity of the existing theory with detailed practical examples and to find distinctive new knowledge by identifying emerging issues from recent NPD processes in the industry. Furthermore, this study establishes an idea generation framework that will potentially enable MNEs to use their research data more effectively when developing real products and to better perform cross-functional tasks.

Transition of natural convection flow on a heated flat plate and inside a heated channel is studied numerically. Three different RANS based turbulent k-ε models namely standard, RNG and Realizable with an enhanced wall function are employed in the simulations. Additionally, a Large Eddy Simulation (LES) technique is also applied to particularly investigate the flow field and transition in a heated plate facing upward. Numerous published papers presented the typical characteristic behaviour of natural convection flow inside a channel, however, none of these provided information about the transition behaviour of flow inside a channel, and importantly, how the transition is affected by the merging of two growing boundary layers which occur inside a channel. Therefore, taking the above important things into consideration, the aim of the study is to carry out in-depth investigations of the transition of the free convection flow inside a channel with an effect of its width, angular orientation and several important thermal and boundary conditions. Moreover, the transition phenomena of the free convection flow developing in a heated channel facing both downward and upward are thoroughly investigated in the thesis. Numerically predicted results are compared with available experimental data in the published literatures. Fluid properties are assumed to be constant except for the density which changes with temperature and gives rise to the buoyancy forces and is treated by using the Boussinesq approach. Air with a Prandtl number of 0.7 is used as a test fluid in all the simulations. In the RANS based models, the results show that the Realizable model with an enhanced wall function predicts numerical results well compared to the experiment than those obtained by the other two models (standard and RNG), therefore this model was selected to perform all the other RANS based numerical simulations in this work. The results particularly indicate that the inclination of the channel has major effects on the transition stage. As the inclination angle is increased, the transition stage moves further downstream of the channel. However, the predicted local heat flux, reached its minimum further upstream of the channel, does not agree with that of the velocity and turbulent kinetic energy in a small channel width. Natural convection from an isothermal plate is conducted by using a Large Eddy Simulation method. The results show that with an increase in the angle the peak of the thermal and velocity boundary layers move from the near outlet of the plate for the vertical case to the middle of the plate when θ = -70°. So the thermal and boundary layers become fatter which causes an early transition.

This thesis depends on the paper &lsquo / Non-Boolean Almost Perfect Nonlinear Functions on Non- Abelian Groups&rsquo / by Laurent Poinsot and Alexander Pott and we have no new costructions here. We give an introduction about character theory and the paper of Poinsot and Pott, and we also compare previous definitions of bent functions with the definition of the bent function in the paper. As a conclusion, we give new theoretical definitions of bent, PN, APN ana maximum nonlinearity. Moreover, we show that bent and PN functions are not always same in the non-abelian cases.

Housing problem had firstly emerged in Ankara after the establishment of Turkish Republic and increased after the 2nd World War. With the population increases in the cities, due to the migration from rural to urban areas, the housing need have increased also as well as the other requirements. Housing Cooperatives that had first developed at 1934 represent a new type of licensed residence. Some precautions such as financial support were taken by the governments to solve this continuously rising housing problem. Therefore, the housing cooperatives had been supported effectively by the governments especially after 1960&rsquo / s. In 1980&rsquo / s, the housing necessity caused different searches in governmental level. Then, a clear resurgence observed in the housing sector with the means of Mass Housing laws accepted. The housing efforts in Adana had been accelerated with the establishments of housing cooperatives after 1960&rsquo / s and the constructions had performed great leaps nearly in every decade. This thesis analyzes the effects of housing cooperatives on the urban development of Adana city.

The aim of this thesis is to develop conservation principles for the brick and tile industry in Eskisehir, one of the symbolic industrial cities in Turkey where brick and tile has been the significant production from the Early Republic Period. The conservation of these structures, complexes and mechanical elements is a controversial issue owing to their physical, economical, social and administrative values. The principles how to conserve and why is searched through discussions on conservation approaches, development plans and values. Focusing on this aim, this study is structured in six parts as the research on industrialization and industrial heritage, review and discussion of value types, survey on brick and tile industry, the value assessment process for the factories with the proposed value types and the implementation of conservation principles. In conclusion, the development of principles is an essential process in conservation of cultural heritage. This thesis proposes conservation principles over physical, social and administrative structure for industrial heritage for brick and tile factories in the Eskisehir Industrial Area.

The territory of Pontus once occupied by the Mithridatic Kingdom in the Hellenistic Period and fell under the Roman Empire in the first century B.C., layed between the Pontus Euxine (Black Sea) and the northern edge of the Anatolian plateau. In his Geography Strabo describes Pontus with a detailed account of the settlements. In his description of his hometown Amaseia (Amasya today), he mentions a plain with 1000 villages called Chiliocomum. Indeed, the archaeological survey data indicates that there were a large number of settlements dating to the Hellenistic and the Roman period in this region. The aim of this thesis is to quantify the settlement - environment relationship and to investigate and compare settlement patterns in the Hellenistic and Roman periods by using Geographical Information Systems (GIS). Data sets are used in the study includes a settlement database, topography, road network, soil and current landuse which were spatially analysed in GIS. Raster analyses, proximity analyses and density analyses are conducted in order to understand and compare site distribution and landuse. The results of the GIS analyses revealed that settlements were located in particular areas of the landscape. Some of these areas continued to be settled from the Hellenistic through the Roman period, while others were abandoned and alternative landscapes have replaced them. The results of the various analyses were utilized to discuss issues related to the shift in the political power and the socio-political structure in the region from the Hellenistic and to the Roman period.

Heat treatment (around 50&deg / C) is a major step in honey filling and packaging that is applied before filtration to decrease viscosity, reduce the moisture level, to destroy yeasts, liquefy crystals and delay crystallization. As a result, formation of Hydroxy Methyl Furfural (HMF), decrease in enzymatic activity, color deterioration, decrease in viscosity and many other structural changes are observed. HMF is produced as a result of Maillard reaction and/or hexose dehydration -which is undesirable-, practically, it is found in fresh honey in low levels, and increases due to heat treatment, storage temperature, pH (acidity) and sugar concentration of honey. HMF level and diastase number are important quality parameters and shelf life indicators of honey. Alternatives of v heat treatment may be the use of ultrasound and high hydrostatic pressure (HHP) to decrease viscosity, liquefy honey and thus minimise adverse affects of heat treatment. Therefore, the aim of this study is to evaluate the effect of HHP (220-330 MPa, 50-60&deg / C, time) and ultrasound (24 kHz) on liquefaction and quality parameters (HMF, diastase number, color and viscosity) of different honey varieties (sunflower, cotton and canola) and to compare the changes with heat treated (50&deg / C and 60&deg / C, time) and untreated honey. Based on the results of the chemical and physical analysis, for HHP treatment the best treatment combination was determined as 220 MPa, 50&deg / C, 106 min. For ultrasound treatment the best treatment combinations were determined as 7 mm probe- 0.5 cycle (batch) applications. On this basis the study points out that Ultrasound and HHP can be suggested as alternative methods to traditional thermal treatment for the liquefaction of honey crystals. When compared to thermal treatment, Ultrasound is advantageous in shorter application times, slight changes in quality parameters and ease in operation. HHP treatment is also an alternative method with shorter application times and lower HMF values.

ABSTRACT MODELING OF CARBON DIOXIDE SEQUESTRATION IN A DEEP SALINE AQUIFER BASBUg, BaSar M.S., Department of Petroleum and Natural Gas Engineering Supervisor : Prof. Dr. Fevzi G&uuml / mrah July 2005, 245 pages CO2 is one of the hazardous greenhouse gases causing significant changes in the environment. The sequestering CO2 in a suitable geological medium can be a feasible method to avoid the negative effects of CO2 emissions in the atmosphere. CO2 sequestration is the capture of, separation, and long-term storage of CO2 in underground geological environments. A case study was simulated regarding the CO2 sequestration in a deep saline aquifer. The compositional numerical model (GEM) of the CMG software was used to study the ability of the selected aquifer to accept and retain the large quantities of injected CO2 at supercritical state for long periods of time (200 years). A field-scale model with two injectors and six water producers and a single-well aquifer model cases were studied. In a single-well aquifer model, the effects of parameters such as vertical to horizontal permeability ratio, aquifer pressure, injection rate, and salinity on the sequestration process were examined and the sensitivity analyses were performed after simulating the field-scale model. The supercritical CO2, one-state fluid which exhibits both gas and liquid-like properties, and gaseous CO2 were sequestered in the forms of free CO2 bubble, dissolved CO2 in brine and precipitated CO2 with calcite mineral in a deep saline aquifer. The isothermal condition was assumed during injection and sequestration processes. The change in porosity and permeability values that might have occurred due to mineralization and CO2 adsorption on rock were not considered in this study. Vertical to horizontal permeability ratio and initial pressure conditions were the most dominating parameters affecting the CO2 saturation in each layer of the aquifer whereas CO2 injection rate influenced CO2 saturation in middle and bottom layers since CO2 was injected through bottom layer.
