In order to host The World Games 2009 in Kaohsiung, all public facilities had been reconstructed in Kaohsiung city. The image of harbor industry Kaohsiung city has been changed and delivered to all over the world through the world media by The World Games. Meanwhile, it promotes the harbor real estates in Kaohsiung as well. In addition to Kaohsiung city¡¦s unique characteristics and public artistic infrastructures, the future development of harbor real estate will become an interesting and valuable issue in Kaohsiung city. This study is based on city marketing, using Analytical Hierarchy Process (AHP), Authorities Survey, and Scenarios Analysis by interviewing 22 authorities of construction companies, real estate brokers, land brokers and real estate developers. To develop a whole process of an assessment of real estate development in Kaohsiung harbor areas by inducing an assessment of real estate development in Kaohsiung harbor areas into three criteria and nine secondary criteria. Furthermore, analyze the future development of three harbor areas, include: Love Pier(which used to be called Pier 12), Glory Pier(which used to be called Pier 13), and Singuang Pier(which used to be called Pier 21). This study finds out that location is the first criterion, value is the second, and construction style is the last in assessment of real estate development in harbor areas. On secondary criteria, integration is the most important issue, convenience is the next; the subject of a talk and plasticity are the last two issues. Base on the whole assessment, Singuang Pier is the most potential area of real estate development in Kaohsiung harbor areas; Love Pier is the next consideration area. This conclusion provides real estate developers an important reference on assessment and decision-making in Kaohsiung harbor areas.

The volume of cargo and passenger traffic of airlines is increasing in Kaohsiung International Airport in the recent years. Due to the rise of environmental consciousness, the aviation noise pollution will lead to public disputes. The transportation bureaus have granted subsidies and compensation on noise prevention in areas around the airport, the subjects are aviation noise prevention zones announced by local governments. Therefore, the classification of aviation noise prevention zone determines the receipt of subsidies and compensation, thus, is concerned by the residents lived in the airport neighboring areas. This study focused on Kaohsiung International Airport, and used the aviation movement data of 2005 as the standard for noise integration model simulation, to understand the variation of the aviation noise in day time and night time under different synarios , as well as the effects on the scope of noise prevention zones. Take Project 1 ( annulling curfew) as an example, the INM simulation of day time and night time aviation noise under various synarios showed that the aviation noise prevention zone of the first scale expanded 10.18 km² as compared to the year of 2005, 4.57 km² for the second scale,and 1.99 km² for the third scale. The estimated Ldn in the target year of 2121 were as follows: the noise volume for susceptible objects of east 27 runway increased 4.7¡ã5.3dB(A), objects near the west side 09 runway increased 3.1dB(A), and objects near the south and north sides increased 3.3~4.8dB(A). In general, the affected area of Project 1 (annulling curfew) ranks the largest, Project 2 (maintaining curfew) the second, and Project 3 (not lengthening the runway) the smallest. As for the affected scale of the aviation noise, KueLing Elementary School and KaoFung Junior College ranked the highest, ZhongZho Elementary School the second, diesel station the lowest. Yet, the actual aviation noise should refer to the results of the noise monitoring station.

In this thesis, we study the dynamic facility location problem with mobile customers considering the permanent facilities. Our general aim is to locate facilities considering the movements of customers in time. The problem is studied for three objectives: P-median, P-center and MINMAX P-median. We show that dynamic facility location problem is a large instance of a static facility location problem for P-median and P-center objectives. In the problem, we represent the movements of each customer in time with a time series. Using clustering approaches, we develop a heuristic approach for the problem with P-median objective. K-means algorithm is used as a clustering algorithm and dynamic time warping is used in order to define similarities between the customer time series. Solution method is tested on several experimental settings. We obtain results, which differ at most 2% from the optimal, in small computation times. Generally, in the literature, MINMAX P-median is solved with a heuristic depending on scenarios planning (see Serra and Marianov, 1998). The heuristic finds an initial solution according to scenarios, later the initial solution is tried to be improved. We provide a bounding procedure on the solution of the problem. The bounds can be used by decision maker to judge the solution quality before proceed. The bounding procedure is also analyzed in different experimental settings.

Multicarrier modulation is a transmission technique that is quite convenient for high data rates in wireless communication. Information symbols are partitioned and parallelly sent over multiple narrowband subchannels. Pulse shaping filters are critically important in multicarrier modulation for determining the characteristics of signal in time and frequency domains. In this thesis, we propose a new pulse shaping approach for multicarrier schemes to increase spectral efficiency in multi-user scenarios. Conventionally, the time-frequency lattice and the prototype filter are designed considering the worst-case of time-varying multipath channel. However, this approach ignores to make use of multi-user diversity and leads to excessive spacings between successive symbols in time and frequency. Unlike the prevalent methods, we investigate user-based filter utilization considering the wireless channel of each user individually to prevent over-design and improve spectral efficiency. Also, this approach is implemented in a denser time-frequency lattice design. Symbols are allowed to be overlapped (depending on time-frequency dispersion of their individual channels) as long as the signal-to-interference ratios (SIRs) observed by all users are kept above a certain level. Employing user-specific filters to enhance SIR of the user exposed to the most interference provides more overlapping flexibility. Therefore, further improvement in spectral efficiency is achieved in our wireless communication system design.

Racism persists individually and institutionally in the U.S. and race-based comedy prevails in media, accepted by diverse audiences as jokes. Media priming and Social Identity Theory theoretically ground this two-part experimental study that examines Latino participants' judgments of in-group (Latino) and out-group (White) alleged offenders in judicial cases after being primed with race-based stereotype comedy performed by an in-group (Latino) or out-group (White) comedian. First, participants read race-based stereotype comedy segments and evaluated them on perceptions of the comedian, humor, enjoyment, and stereotypicality. Second, participants read two criminal judicial review cases for alleged offenders and provided guilt evaluations. Importantly, a distinction was made between high and low Latino identifier participants to determine whether racial identity salience might impact responses to in-group and/or out-group members in comedy and judicial contexts. The results reveal that the high Latino identifiers found the race-based comedy segments more stereotypical than did the low Latino identifiers. Latino participants rated the comedy higher on enjoyment when the comedian was perceived to be a Latino in-group member as opposed to a White out-group member. The high Latino identifiers rated the White alleged offender higher on guilt than the Latino alleged offender after being primed with race-based comedy. Simply projecting in-group or out-group racial identity of comedians and alleged offenders with name manipulations in the study influenced how participants responded to the comedy material, and persisted in guiding guilt judgments on alleged offenders in the judicial reviews based on participants' Latino identity salience. A Latino comedian's position as popular joke-teller in the media overrides in-group threat, despite invoking in-group stereotypes in humor. Even with greater enjoyment expressed for Latino comedians' performing stereotypical race-based material, the tendency to react more harshly against perceived out-group members as a defense strategy to maintain positive in-group salience remained in real-world judgments on alleged offenders. Despite the claim that light-hearted comedy is meant to be laughed at and not taken seriously, jokes that disparage racial groups as homogeneous, simplistic, and criminal impact subsequent responses to out-group members in a socially competitive attempt to maintain positive in-group identity, to the detriment of out-groups.

A comprehensive experimental study has been conducted using Particle Image Velocimetry (PIV) for a wide array of ventilation schemes and mining configurations for the purpose of examining ventilation characteristics in dead end mine headings. Flow behaviors in two basic mining sequences of box and slab cuts for 30 ft and 60 ft deep cuts were studied. The present thesis discusses the effect for various geometric and flow parameters including the variation of inlet flow velocities, entry heights, face zone widths and curtain widths on the flow behavior. The Reynolds number Re considered for this study ranges from 1 105 to 3 106 based on curtain width and exit velocity. The variation of the face zone and the curtain widths considerably affected the flow behavior, resulting in recirculation regions in the face area for critical combinations. Jet spreading angles and virtual origins have been calculated for the different geometries showing that an optimum range of face and curtain widths exists. A detailed discussion employing various scenarios for exhaust ventilation systems has also been made. Full-size measurements and comparison of the experimental data with numerical simulations is presented. Implementation of machine-mounted scrubbers in the blowing system are discussed for different values of the ventilation ratios (Qs/Qin) ranging from 14% to 53%. The scrubber system, typically introduced for dust collection, is also shown to be a useful tool in providing adequate ventilation to the immediate face area.

After the nuclear fallout in Japan, Germany decided to back out from nuclear energy while at the same time changing the energy supply from fossil to renewable sources. This elaborate plan, known as Energiewende, will require significant economic and structural efforts that will have profound impacts on the environment and society itself. It is therefore crucial to identify possible technological pathways that can lead to a renewable energy supply, while reducing negative impacts on a holistic scope. In order to analyse alternative energy technology scenarios in Germany, this thesis focuses on the development of an indicator-based numerical Sustainable Energy Systems (SEnSys) model approach. Other than previous approaches, the SEnSys model considers full aggregated impacts of technological pathways leading to future configurations. With the help of an exemplary case study on two alternative energy technology scenarios (Trieb1 and Trieb2), the feasibility of the SEnSys model in evaluating sustainability is subsequently assessed. The results can affirm the findings of previous studies concerning lower economic and environ- mental impacts for scenario Trieb2, with small shares of renewable energy imports, compared to scenario Trieb1 based on only local but fluctuating renewables. Additionally, the results are in accordance with other relevant studies, while offering new valuable insights to the topic. Given a comprehensive revision of the identified uncertainties and limitations, it can be stated that the SEnSys model bares the potential for further analysing and improving sustainability of energy technology scenarios in Germany and other countries.

Coal has been used as a fuel for electricity generation for centuries. Inexpensive electricity from coal has been a key component in building large industrial economies such as USA and China. But in recent decades the negative aspects of coal, mainly carbon dioxide emissions, has changed the view on the fuel. Carbon capture and storage (CCS) is a solution to be able to continue using coal as an energy source, while limiting carbon emissions. One of the drawbacks of CCS is the energy need associated with the capture process, the energy penalty. This study aims to gather and analyze the energy penalties for the most developed types of carbon capture technologies. It also aims to model how the implementation of CCS would affect the future coal consumption. The results show that the range of energy penalties for a given type of technology is wide. Despite obtaining the energy penalty with the same simulation software, the energy penalty for post- combustion with MEA can range between 10.7% and 39.1%. Comparing mean energy penalties show that pre-combustion capture is the most efficient capture method (18.4% ± 4.4%) followed by oxy- fuel (21.6% ± 5.5%) and post-combustion (24.7% ± 7.9%). Further on, CCS implementation scenarios were compared and used as a starting point for coal consumption calculations. Three pathways were constructed in order to investigate how different distributions of technologies would affect the amount of needed coal. The pathways describe a implementation with only the most efficient technology, the least efficient and a middle option. The results suggest that a large scale implementation of CCS on coal power plant will have a significant impact on the global coal consumption. Under certain assumptions it takes up to 35 % more coal to deliver the same amount electricity with CCS in comparison without CCS. It is also found that certain implementation scenarios will struggle to produce the amount of coal that is needed to power the plants. A sensitivity analysis was performed to examine the impact of assumptions made on for instance plant efficiencies. The analysis shows that optimistic assumptions on development in plant efficiency and deploying only the best technology, uses less coal than a development without CCS and with current plant efficiencies.
