Harmonizace britské a evropské identity v technologickém projektu / Harmonising British and European Identity in a Technological Project

White, Stephen Washbourn January 2017 (has links)
This research project will focus on the relationship between technology and integration. In practise, this means taking a transnational European project and using it as a lense in political and social discourse to trace how Britain and Europe have been placed regarding each other, and the implications this has for British identity. The chosen technology is the Eurofighter Typhoon, whose development involved numerous European nations ranging from Spain to France and Germany. The work seeks to contribute into the historiography focusing on identity in Britain's Europhile versus Eurosceptic debate, and the growing field of technological history spearheaded by works linking technology and the co-construction of national identities. Keywords: Technology, Integration, Europhile, Eurosceptic, Britain, Europe, Eurofighter.

Study on the change of coastal topography-A case study of Fu-Long coast

Liu, Chia-Cheng 20 July 2011 (has links)
The reasons to cause the variation of the Fu-Long resort area have been investigated in the study. The resort area is the spit extended from the northern coast of the Shung-si River located at the northeast part of Taiwan. Historical coastlines and the bathymetry surveyed in the last 15 years have been used to interpret the cause of the coastline variation. Numerical simulation of the wave and flow field is performed to assist the interpretation. It is found that the spit may be eroded during typhoon season by the flood from Shung-si River and recovered in the next year if the typhoon occurred in monsoon season in which the eroded sediment carried by northward monsoon waves will be merged to the coastline by the following southward northeast season waves. On the contrary, if the typhoon occurred during northeast wind season, the accompanying southward will carry the eroded sediment further south and the spit may not recover in the next year. It is further found that the source of the sediment from the river has been decreased in the last decade and the coastline retreated in responding the source decrease. Man-made fishery port close to the spit also deposited some sediment and may cause the variation of the coastline.

The spatial and temporal variability and budget of suspended sediment in Taiwan major rivers

Chueh, Sheng-An 17 July 2012 (has links)
¡@¡@Sediment loads of Taiwan rivers have increased in recent years because of frequently recurring typhoons. In addition to the dry and wet seasons causing sever erosion and deposition of the riverbed, the long-term records from 1967 to 2009 of suspended sediment concentration and daily discharge observed by the Water Resource Agency in Taiwan Rivers were used in this study. ¡@¡@To understand the sediment deposition or erosion in the rivers, we need to find how the discharge and sediment load interact with each other under the natural and human influences. The hydrological data we used in this study were from Water Resources Agency¡¦s annual reports, including the Danshui River, the Lanyang River, the Zhuoshui River, the Beinan River, and the Gaoping River. ¡@¡@High turbidity happen when sediment concentration exceeds 40 g/L. Judging by this threshold, taking upstream stations of the Zhuoshui River for example, the Nei-Mao-Pu Station (1973-2009) reached this threshold 6 times, Bao-Shih Bridge Station (2004-2009) 19 times, and Yun-Feng Bridge Station (1995-2009) 19 times. But Yen-Ping Bridge Station (2004-2009), which is at the middle part of Zhuoshui River, has never reached the threshold, became the erosion rate and sedimentation rate are balanced here. Chi-Chou Bridge Station (2000-2009) at the downstream reached the threshold for 11 times too. ¡@¡@According to the river graded profile, in the Danshui River, obvious erosion occurred at the Liu-Kwei Bridge Station in 2000, the Po Bridge Station in 2001, and San-Hsia (2) Station in 2004 and 2007. In the Zhuoshui River, significant deposition took place at the Yun-Feng Bridge Station in 2006 and 2010. In the Gaoping River, deposition occurred at the A-Chyi-Ba Bridge Station in 2000, while erosion occurred at Liu-Kwei Station in 2001 and at the A-Chyi-Ba Bridge Station in 2007 and 2008. ¡@¡@Above results show that the major sediments are deposited upstream, forming a temporary sediment storage source region, such as at Li-Lin Bridge Station, Liu-Kwei Station, and Yun-Feng Bridge Station at the Gaoping River, all of which have reached the threshold when a typhoon comes. Investigating daily rainfall data from Taichung Weather Station in 2005, we find that besides typhoon influences, when the rainfall is exceeding 200 mm High turbidity events would occur in the Jhoushuei River. ¡@¡@According to our study, we find that most sediment deposits at the upper reaches, forming temporary sediment storages, so when a typhoon comes, we can see the sediment downstream is often mixed with the sediment coming from upstream storages. That is because the slope in the upper reaches is steeper, and heavy rain makes the temporary deposit easy to erode. On the contrary, the slope in the lower reaches is more gentle so it is easier for sediment to deposit, which is the reason why the stations at downstream often reach the threshold. When the extreme weather occurs, the temporary sediment storages along the entire river course become the source regions to release the sediment out to the sea.

Effects of Rainfall and Polysilicon Industrial Pretreated Effluent on Biological Nitrogen Removal

Lu, Yi-chieh 04 September 2012 (has links)
The biological treatment is one of the commonly methods of wastewater treatment plant in wastewater treatment processes. The biological treatment can meet water quality standards required by the plant in response to different sewage conditions and qualities. It can purify high pollution loading sewage through the use of microbial metabolic transformation. Through effectively protecting and using water resources, the ecological balance of ocean and river can be maintained and environmental quality can be improved in consequence. This study analyzes the operations of a wastewater treatment plant, which is part of an urban sewage system. The major sources of inflow to the plant are domestic sewage, followed by rainfall runoff and industrial wastewater. The biological treatment system adopted in the plant is "Biological Nutrient Removal (BNR)". The reason for using BNR is to prevent eutrophication of downstream water bodies due to untreated nitrogen, phosphorus and other nutrient substances in discharged sewages. The design of BNR, which is called "A2O activated sludge method", would increase the anaerobic-anaerobic mixing process for simultaneous removal of the sewage of organic carbon, nitrogen, phosphorus and BOD. The study collected the data to analyze the impacts of extreme weather event, i.e. Typhoon Morakot, and the effects of newly developed industrial, i.e. polysilicon industry. Water quality data of inflow and outflow sewages starting from January 2009 to December 2011 were compiled to perform statistical analyses. By plotting various time series figures, the study can effectively explore the variations of pollutant removal under the two designated situations in the biological treatment system. The results show the abnormal increase in conductivity of effluent which has decreased pollutant removal since August 2010. Besides, the confluence of rainwater and sewage has severely affected the efficiency and quality of the biological treatment process during a typhoon or heavy rain event. This study has identified the potential impacts on a BNR plant which can provide the administration to enhance the effectiveness of the biological treatment plant and the function of sewage purification stability control.

Modeling biomass and nutrient dynamics in seagrass meadows (Thalassia hemprichii)

Tsao, Ruei-Jiuan 02 July 2007 (has links)
This study refers to developed ecological model abroad, and established the seagrass model with MATLAB compiler. I also took the seagrass meadows in south Taiwan-Nanwan for my studying case, and simulated the dynamic effect of seagrass and epiphyte biomass, as well as nutrient, and attempted to go on probing into the cause with northeast monsoon and typhoon. The simulating site of this study was Nanwan, which is located at Hengchun Peninsula, the southern tip of Taiwan. The dominant species in this area is Thalassia hemprichii. South Taiwan is situated at a tropical climate, and the variation of air temperature is small. Additionally, Kurshio embranchment cause the variation of water temperature smaller, about 24 (¢J) to 30 (¢J).The northeastern monsoonal winds, formed downhill winds, are extremely forceful from October to April, so the wind speed is greater during this period than the rest of the year. In South Taiwan, dry-wet season is clearly. The dry season is from November to April, and the wet season is from May to October. The main rainfall comes from southwest monsoon, especially summer typhoon (June to September). The wind speed is raised abruptly by typhoon and makes water agitate, which not only cause the mortality raising but also the sediment turbulence. By Lin¡¦s research (2005), the growing area of seagrass meadow in Nanwan is a half-closed tidal pool where human makes huge effect and there is a lot of drainage of house and inn sewage. Furthermore, these seagrasses in Nanwan would be exposed to air during the period of poor tide and the emerged period is the longest of these three areas -Nanwan, Dakwan and Wanliton. The seasonal dynamic of seagrass, which is located in the high site of intertidal zone, is obvious, and the biomass is larger in summer than in winter; but that is not obvious in the low site and tidal pool. By the seasonal condition and some specially climate condition mentioned above, the analysis of simulate cases would be go on. Comparing of the modeling result and real measurement, the seasonal changing situation mostly match up. No matter high site (emerged and dried) or low site, there is the maximum of seagrass biomass (including above ground, below ground, or shoot density) in summer, and the minimum in winter. Typhoon causes the biomass losing abruptly in summer. R/S ratio (below-ground biomass division above-ground biomass) is bigger in winter than in summer. On one hand the inside nitrogen redistribution is larger in summer, because the larger growth rate occurs in summer, and the more nutrient is supplied from roots, on the other the redistribution is smaller in winter cause the less nutrient is supplied from roots. Epiphyte biomass has the maximum in summer, when the nutrient concentration of water is larger. In the section of the difference between low and high site seagrass, it is apparent that the high site seagrass would be exposed to air and dried by northeast monsoon. Although typhoon comes up, its influence is not so strong as northeast monsoon at high site. The maximum biomass still occurs in summer, and it is presumed that the living environment of high site seagrass is with more pressure by nature. The above-ground biomass of high site seagrass is smaller than low site, but the below-ground biomass is much lager at high site. Besides, shoot density is larger at high site. The biomass of epiphyte is larger at low site just opposite to shoot density. It is supposed that high site seagrass is emerged to air and limited by environment factors so above-ground biomass would be reduced and store up the sustenance to below-ground biomass. It is conjectured that the main factor with shoot density is affected by light density and below-ground biomass. In shallow water, the seagrass at high site could accept more light energy, moreover the below-ground biomass is sufficient and the recruitment rate is large, thus there are more shoots at high site. Epiphytes are also limited by water depth and wind, and the biomass of epiphyte at high site is smaller than at low site.

The distribution of Trichodesmium in the South China Sea and the ecological factors that affect it

Chang, Shih-Tai 02 June 2001 (has links)
Abstract This research investigated the distribution of Trichodesmium in the South China Sea and the ecological factors that affect it. The survey periods were from August 1999 to October 2000. A total of 5 cruises were conducted, mostly in summer and autumn, including cruise 559 (August 18~25, 1999), cruise 629 (May 22~27, 2000), cruise 588 (July 3~14, 2000), cruise 597 (October 4-13, 2000), and cruise 657 (October 16-21, 2000). The sampling stations were located on the continental shelves, the slope zones, and the basin in the South China Sea between 13~22∘N and 114~120∘E. The density of Trichodesmium in the South China Sea varied greatly among the continental shelves, the slope zones, and the basin zones. Trichodesmium density in the continental shelf and the slope was high, with an average density of 150¡Ó297¡Ñ103 trichomes/m3 (4~1008¡Ñ103 trichomes/m3) in the surface water and 151¡Ó322¡Ñ103 trichomes/m3 (13~1114¡Ñ103 trichomes/m3) in 2-60m water depth. This could be caused by the influence of the mixing of the Kuroshio water and the substances of terrestrial origin. In the basin, Trichodesmium density was low, with an average density of 5¡Ó7¡Ñ103 trichomes/m3 (0~22¡Ñ103 trichomes/m3) in the surface water and an average density of 6¡Ó7¡Ñ103 trichomes/m3(0~22¡Ñ103 trichomes/m3) in 2~60m water depth. The Trichodesmium communities are mainly composed of T. thiebautii and T. erythraeum, with T. thiebautii being more abundant than T. erythraeum. Their relative importance at the continental shelf and the slope zones was 58% and 36% respectively, and 64% and 31% in the basin respectively. Trichodesmium appeared commonly as a single trichome, rarely in colony. The vertical distribution of Trichodesmium concentrated at 0-100m. The highest density was near the surface, varying between 4~1008¡Ñ103 trichomes/m3. In summer, the Trichodesmium in the continental shelf and the slope zone of the South China Sea was slightly higher than that in the East China Sea. The influences of temperature, nutrient abundance and wind speed on the distribution of Trichodesmium are not obvious. Trichodesmium in shallow water became abundant after the passage of a typhoon. The maximum density of Trichodesmium was observed in shallow water and average number of trichome per colony decreased. The influences of the typhoon on Trichodesmium species composition and colony density were not obvious. High density of Trichodesmium occurred at shallow waters and the water column with low stratification index (SI) which repressed the properties of waters in the continental shelf and the slope zones. The regions in which high-density Trichodesmium appeared, were the continental shelves and slope which showed water properties similar to those of the Kuroshio water, indicating possible intrusion of the Kuroshio water in summer into the continental shelves and slope of the northern South China Sea.

Effects of tropical cyclone on air pollution in Hong Kong

Li, Tuonan 05 May 2020 (has links)
Climate and weather play a significant role in patterns of air pollution occurrence and severity. An analysis of the effect of weather on pollution parameters in Hong Kong was performed. Hong Kong is one of the world's most densely populated regions and air pollution can be problematic, which is a serious public health concern. Hong Kong is impacted by Tropical Cyclones which strongly affect weather patterns. In this research, a twelve-year record (2007-2018) of tropical cyclone (TC) and pollutant concentrations (carbon monoxide, ground-level ozone, nitrogen dioxide, sulfur dioxide, and particulate matter) were analyzed to investigate the effects of TC on air quality. It is found that the occurrences of TC are strongly related to days with elevated particulate matter, sulfur dioxide and carbon monoxide concentrations (above 90th percentile), and low concentrations (below the 10th percentile) for nitrogen dioxide. In particular, the spatial location of TC with respect to Hong Kong is found to be clearly associated with high or low pollutant concentrations. When the TC is located to the North/Northeast of Hong Kong, the air quality tends to be poor because polluted air from mainland China is advected over the city. Conversely, TC located to the West resulted in good air quality by ventilating the city with relatively clean air from the ocean. / Graduate

A Reanalysis of the 1916, 1918, 1927, 1928, and 1935 Tropical Cyclones of the North Atlantic Basin

Glenn, David Allen 06 August 2005 (has links)
This thesis research involves a reanalysis of the National Hurricane Center?s Atlantic Basin Hurricane Database (HURDAT) for 1916, 1918, 1927, 1928, and 1935. Newly available meteorological records from ship logs (COADS) along with recently discovered historical documents were used to reassess tropical cyclone location and intensity. Tropical cyclone track and intensity alterations are discussed in detail in a supporting metadata file. The overall results of the reanalysis process were minor alterations, with some major changes, to the track and intensity of tropical cyclones in HURDAT. Four tropical storms were added: one in 1918, one in 1927, and two in 1935. Three tropical storms were deleted: one in 1918 and two in 1916. However, the overall tropical activity remained nearly the same for the study period. This research is significant because it will strengthen our understanding of hurricane climatology and improve forecast models that utilize HURDAT.
