Nowadays, the economic grows fast and changes a lot. Meanwhile, the central city gets bigger and bigger. More and more buildings locate everywhere while people enjoy their modern life. The needs of electricity grow by the way. In order to provide more power, the Power Company has tried very hard to find new resources. However, there is another problem when transferring the power through crowded city. To avoid the geographic limitation, most of the overhead lines have been changed into under ground lines instead. Sooner or later, the under ground cable will become the main power transmission. This thesis focuses on the current rating distribution of Taiwan 161KV line with various PE underground cables that contain one circuit, two circuits, four circuits, and eight circuits. The current rating goes within various pipes. To find the best economic benefit with the lowest investment by rearranging the pipes to reach the most current rating and by matching the current rating from under ground cable with the over head cable is the main goal of this thesis. JCS NO.168 analyzes the set up map for all the pipes. In order to offer the best power supply, to maintain the longest cable life within the acceptable working days, the calculating scripts support to figure out the current rating in shortest time.

Beginning prior to the foundational study conducted by Felitti et al. (1998), individuals of all ages have been exposed to a variety of traumatic events that had the capacity to alter overall functioning in a variety of ways. Children and adolescents are a vulnerable subset of individuals who are often exposed to various types of trauma which has the capacity to impact academic, behavioral, and social/emotional functioning (Cohen, Berliner, & Mannarino, 2010). The adverse effects related to trauma exposure in children and adolescents have been correlated with externalizing and internalizing disorders, and decreased academic performance (American Psychiatric Association, 2013). An individual’s proximity, or closeness, to traumatic events has also been correlated with increased negative outcomes to include meeting diagnostic criteria for Post-Traumatic Stress Disorder (PTSD). There is a gap in the literature, however, in determining the relationship between proximity to traumatic events and its impact on academic functioning in elementary students. The present study sought to analyze the relationship between PTSD symptomology and academic achievement in elementary students while determining if proximity was a moderating factor in the hypothesized relationship. Participants included 81 children in Grades 3 through 5 enrolled in elementary schools in a school district in the Southeastern United States. Linear regression analyses indicated the hypothesized relationship between PTSD symptomology and academic achievement was nonsignificant. However, when proximity was included as a moderator the increase in variance of explanation of the relationship was noted to be significant. Implications of these results suggest that inclusion of proximity as a pertinent contributor to adverse reactions may be imperative in engaging in prevention, intervention, and postvention strategies for elementary students exposed to trauma.

Flux trapping and cycling energy losses were studied by vibrating sample magnetometry in fine multifilamentary Nb-Ti superconductive strands for which proximity effect coupling between the filaments is significant. Measurements were made to determine the influence of helical twist about the strand axis as well as sample length for strands experiencing varying levels of proximity effect coupling. The proximity effect strength was varied by investigating strands with a range of filament diameters, as well as by the addition of magnetic impurities to the interfilamentary medium (the matrix) to suppress the proximity effect. Critical currents and fields for the matrix were extracted from the measurements. The reduction of cycling loss1 and magnetization2 previously found was confirmed. Additionally, these measurements were extended to strands where little twist was applied, and the magnetization and cyclic loss were found to saturate. Bean-like models for anisotropic media introduced by Carr1 and later Harada2 were further developed to calculate magnetization and penetration fields in these strands over a large range of twist pitch values. A calculation of magnetic hysteresis loops was also made for short strand samples. These models provide a good qualitative understanding of the observed behavior and lead to useful predictions for applications. / Department of Energy

Proximity Warning Systems are currently the focus of many research groups. Their goal is to produce a system that will reduce the number of run over incidents that occur in large mobile equipment operations. A majority of these incidents occur when the equipment starts from the In-rest state and begins to move. The addition of a transmission locking mechanism to a GPS based proximity warning system will prevent more run over incidents. This transmission locking mechanism will automatically prevent equipment from moving when there is a high risk for a potential run over incident to occur. Additional safety and optimization for surface equipment can be provided by utilizing GIS software for data analysis just by using the data collected from a GPS based proximity warning system. Combining these ideas and methods can provide better safety for large mobile equipment operations. / Master of Science

This investigation examined whether children can code the relative proximity of two objects to a landmark and whether they use verbal or nonverbal strategies to remember a target location. Two- to 2.5-year-olds completed a memory task where they watched an experimenter hide two different toys in two identical containers placed 2 and 12 inches from a landmark. The experimenter either used neutral language (e.g., “here”; Experiment 1) or spatial labels (e.g., “close/far”; Experiment 2) to describe objects’ hiding locations. After hiding, children were carried outside the enclosure to a new viewpoint during a 10-second delay and then looked for a target toy. Experiment 2 also included language measures: parent reports of children’s general and relational vocabularies and performance on a language task, which measured children’s understanding of spatial (close/far) and color (red/blue) terms. We found that children successfully coded relative to proximity to a landmark in the memory task. However, hearing spatial labels during hiding in Experiment 2 did not improve performance relative to Experiment 1, and children’s spatial term comprehension in the language task did not predict memory task performance. We also found that children’s productive relational vocabulary predicted memory task performance; however, children’s color term comprehension in the language task was the strongest overall predictor of memory task performance. Collectively, these results suggest that children initially rely on a nonverbal strategy when coding relative proximity to a landmark in a memory task and that children who are better at forming abstract categories may code relative proximity more successfully.

This dissertation describes experimental studies of the superconducting proximity effect in single-crystal Pb, Sn, and Zn nanowires of lengths up to 60 um, with both ends of the nanowires in contact with macroscopic electrodes that are either superconducting (Sn or Pb) or non-superconducting (Au). The Pb, Sn, and Zn nanowires are fabricated using a template-based electrochemical deposition method. Electric contacts to the nanowires are formed in situ during electrochemical growth. This method produces high transparency contacts between a pair of macroscopic electrodes and a single nanowire, circumventing the formation of oxide or other poorly conducting interface layers. Extensive analyses of the structure and the composition of the nanowire samples are presented to demonstrate that (1) the nanowires are single crystalline and (2) the nanowires are clean without any observable mixing of the materials from the electrodes. The nanowires being investigated are significantly longer than the nanowires with which electrode-induced superconductivity was previously investigated by other groups. We have observed that in relatively short (~6 um) Sn and Zn nanowires, robust superconductivity is induced at the superconducting transition temperatures of the electrodes. When Sn and Pb nanowires are in contact with a pair of Au electrodes, superconductivity is suppressed completely. For nanowires of 60 um in length, although the suppression of superconductivity by Au electrodes is only partial, the induced superconductivity at the higher transition temperatures of the electrodes remains full and robust. Therefore, an anomalous superconducting proximity effect has been observed on a length scale which far exceeds the expected length based on the existing theories of the proximity effect. The measured current-voltage characteristic of the nanowires reveals more details such as hysteresis, multiple Andreev reflection, and phase-slip centers. An interesting relation between the proximity effect and the residual-resistance-ratio of the nanowires has also been observed. Possible mechanisms for this proximity effect are discussed based on these experimental observations.

Delivering the right information to the user is fundamental in information retrieval system. Many traditional information retrieval models assume word independence and view a document as bag-of-words, however getting the right information requires a deep understanding of the content of the document and the relationships that exist between words in the text. This study focuses on developing two new document ranking techniques, which are based on a lexical cohesive relationship of collocation. Collocation relationship is a semantic relationship that exists between words that co-occur in the same lexical environment. Two types of collocation relationship have been considered; collocation in the same grammatical structure (such as a sentence), and collocation in the same semantic structure where query terms occur in different sentences but they co-occur with the same words. In the first technique, we only considered the first type of collocation to calculate the document score; where the positional frequency of query terms co-occurrence have been used to identify collocation relationship between query terms and calculating query term’s weight. In the second technique, both types of collocation have been considered; where the co-occurrence frequency distribution within a predefined window has been used to determine query terms collocations and computing query term’s weight. Evaluation of the proposed techniques show performance gain in some of the collocations over the chosen baseline runs.

In 2008, the Taiwanese film ¡§Cape No. 7¡¨ set the record of 500,000,000 box offices. Then this year also has the hot movie ¡§Wanhua¡¨. People start to expect the native movie industry economy is improving gradually. However, according to the overall box office, Hollywood still holds 80% market. Local film industry who want to get back lost audiences and change their long-standing habits of going to the cinema is to see Hollywood films, should be more understanding of the consumer behavior of the movie going and the underlying factors. This study is from the audience perspective and use of the consumer behavior theory to compare on consumer decision-making for Taiwanese and Hollywood Films. Then find out how product attributes, motivation and cultural factors in the film will influence the attitude toward Taiwanese and Hollywood films and the willingness to see these movies. Finally we can understand why most audiences are prefer Hollywood than Taiwanese films and get the meaning of movie marketing. According to the SEM analysis in this study, leisure motivation and word of mouth factor influence the attitude of Taiwanese films most. And effect factor of the attitude of Hollywood films are leisure motivation and degree of recognition of cultural values in movies.
