Abstract:
There is a great need for competent teaching of Business English in tertiary institutions in Vietnam. At the Hanoi Foreign Trade College (HFTC) alone, about 150 students per year seek training to equip them to work in export and import organizations, banks for foreign trade and customs departments. In teaching such students, one problem is the provision of interesting and relevant materials. This study addresses the question of selection of materials and techniques for teaching business English listening skills. This Field Study Report consists of five chapters.

Abstract:
Using NASDAQ high frequency trading (HFT) and minute-by-minute Limit Order Book (LOB) data over 120 sample stocks in 10 weeks between 2008-2010, including the week of the Lehman Brothers crisis, we study how trading activities of HFTs, NHFTs (Non-HFTs) and their order placements interact, and affect overall market quality. We capture order placements via the depth (step) and the height (price) dimensions along the LOB. We first document that HFTs are active not only at the top of the LOB, but their orders are placed along the LOB with an average around the 5th step, slightly ahead of NHFTs wh

Abstract:
Sveriges samlade skogsindustriföretag förutspår en förlust av marknadsandelar, eftersom man inte lyckas hålla samma tempo på produktionen som många andra länder. En orsak till detta är att skogsmaskinerna är för långsamma. Skotarna, vars uppgift är att förflytta virket från avverkningsplatsen till en uppsamlingsplats, bär en stor del av skulden. De hinner inte transportera virket tillräckligt snabbt. För att råda bot på detta ska en ny typ av skotare utvecklas, vars plattform inspireras av försvarsteknologi.

This paper studies how high-frequency trading (HFT) affects the Swedish stock market quality based on volatility and liquidity measures. Previous studies show ambiguous results where a few propose that HFT deteriorates market quality by increasing volatility and decreasing liquidity while some studies point in the opposite direction.By setting up a simultaneous equations system with instrumental variables and estimating the parameters with Generalized Methods of Moments (GMM), this paper finds that in the majority of the investigated stocks high-frequency trading activity reduces bid ask sprea

碩士<br>國立交通大學<br>電信工程系<br>87<br>In this thesis, we have designed and implemented EDFAs for HFC networks applications. We first studied the properties of EDFA, especially the gain model and gain dynamics. Finally, we designed and implemented two kind of EDFAs, one for power amplifiers in the head end and another one is suitably used with DWDM techniques.

Abstract:
This master thesis deals with methods of automatic recognition of bird species by their voices. In first, I defined the database of records and created a reference data by handmade evaluation. The next step is to find the optimal features for describing a bird singing. I use a Human Frequency cepstral Coefficients (HFCC). For the best accuracy of recognition is necessary to correctly classify a bird's vocalization from a non-vocalization segments. The VAD system is based on an algorithm k-Nearest Neighbours. The last step describes the system based on Hidden Markov Models which allows to recog

碩士<br>國立臺灣科技大學<br>化學工程系<br>90<br>The purpose of this paper is to investigate the two-step growth of MOCVD copper using Cu(hfac)2 as the precursor. In the first step, we pre-deposit Cu2O films with water as the additive because precursor’s partial pressure is unstable during deposition without water additive. In contrast to H2, H atoms which are produced due to dehydrogenation reaction of ethanol alcohol can be used to reduce Cu2O films at lower temperatures and enhance the reaction rate .The Cu atom in Cu2O films(24％) is the catalyst. The mixture of ethanol alcohol and water can be

碩士<br>聖約翰科技大學<br>電機工程系碩士班<br>99<br>The decision accuracy of hardware/software partitioning is now playing a key role towards success for an embedded system design. Recently, meta-heuristic algorithms such as GA or PSO are often exploited for solving the decision problems. Unfortunately, the use of single fitness value for the algorithm is difficult to present the design quality that concerned the factors of performance, cost, power consumption, communication latency and chip area, etc. So that bad decisions are often obtained. In this paper, we proposed a novel Hot Function Task Group (HFTG) f

Abstract:
碩士<br>元智大學<br>生物科技與工程研究所<br>99<br>A Pseudomonas strain TeU resistant to tellurite (TeO32-) and cadmium (Cd2+) ions was isolated from heavy-metal contaminated sediments by enrichment. Transposon mutagenesis of strain TeU resulted in mutants exhibiting Cd2+ sensitivity (Strain BU21) and one with decreased ability to reduce tellurite (strain AU08). Genes encoding an HflKC complex and an putative metallopeptidase were identified to be associated with the bacterium’s ability for tellurite reduction and cadmium resistance, respectively. We have cloned and sequenced the hflC and metallopeptidase gene

Abstract:
The demands facing the refrigeration industry are minimal usage of conventional energy sources for compression and avoidance of ozone depleting substances. One of the approaches to combat these issues is the use of thermally driven solid sorption compression with non-ozone depleting refrigerant. In this context, the research work presented in this thesis is devoted to a comprehensive thermodynamic analysis and development of a laboratory model of an activated carbon+ HFC 134a adsorption refrigeration system. The cooling load catered to by the laboratory model is 2-5 W, mainly for thermal manag
