Abstract:

In Vietnam today there is an urgent demand for well-designed tests of listening comprehension. Little attention has been given to this problem. This field study is intended to provide guidance on the design of listening comprehension tests and in particular for intermediate level students at the Hanoi Foreign Language College (HFLC). The Field Study Report consists of six chapters. Chapter One gives a brief introduction which covers the problem, aims, subjects (testees) and the background of the Field Study Report. Chapter Two deals with the purposes of testing in some detail, setting this in

Abstract:

This study examines the problems of constructing and administering a test of spoken English for Vietnamese EFL teacher-trainees. In an attempt to standardize the assessment, a planned oral interview was pilottested with a group of ten Vietnamese EFL teachers currently enrolled in a Graduate Diploma Course in TESOL at the Canberra College of Advanced Education, Australia. Results of the study indicate that the validity and reliability of such measurement can be achieved if certain carefully outlined procedures in planning the test and training the testers are carefully followed.

Abstract:

Members of the ubiquitous GTPase superfamily regulate numerous cellular functions. A core group of eight GTPases are present in all domains of life: initiation factor 2, elongation factors Tu and G, protein secretion factors Ffh and FtsY, and the poorly characterized factors YihA, YchF, and HflX. While the first five members have well defined roles in the essential cellular process of protein synthesis, a role for YihA, YchF and HflX in this process has only recently been suggested. Here, a detailed kinetic analysis examining the interaction between HflX and its cellular partners is described.

In such cases, fireresistant, water-based hydraulic fluids are in demand. A special feature of these liquids is their high cavitation tendency and the associated strong erosion wear.

The refrigerant charge reduction in HVAC\R systems is an important issue because it falls within environmental policies regarding refrigerants contributions to the greenhouse effect. A way to move toward charge reduction is to increase the compactness of heat exchangers, which means more complex designs of the evaporators. Nevertheless, while a large amount of studies have has been published on the thermal and hydraulic analysis of flow boiling of refrigerants in horizontal tubes, very little attention has been given to flow boiling in geometries different from straight tubes.

碩士<br>國立臺北科技大學<br>能源與冷凍空調工程系碩士班<br>102<br>The main purpose of this study is to analyze and discuss the effectiveness of the green refrigerant HFC-152a as a replacement for the refrigerant HFC-134a. Two experiments were conducted, involving one refrigerator and one dehumidifier, respectively, both of which are commercially available and vapor compression cycle system based. In the experiments, these appliances were initially tested for refrigerant performance with their original HFC-134 refrigerant systems and then tested with the alternative refrigerant HFC-152a. Subsequently, analysis was per

In this thesis, we investigate the effects of HFC MAC control protocol on TCP performance and propose a new adaptive FCFS MAC scheduling and allocation algorithm which comprising "Fast Request Transmission" and "Long Packet Deferring" mechanisms, which can help improve the TCP performance substantially in terms of downstream throughput, upstream channel access delay an

碩士<br>國立臺灣大學<br>植物病理與微生物學研究所<br>97<br>To investigate serS gene in peanut witches’-broom (PnWB) phytoplasma, subgenomic libraries of PnWB phytoplasma were constructed in this study. Clone lib_speI_4-19 was obtained from the PnWB phytoplasma SpeI-restriction subgenomic library by colony hybridization using PCR- amplified probe WS2-5 based on the partial sequence of serS gene of PnWB phytoplasma obtained in our previous study. To obtain the 5’ end sequence of serS, another probe WS8-6 was amplified based on the sequence of cloned fragment of lib_speI_4-19. Clone lib_HindIII_2-36 was then selec

Abstract:

碩士<br>國立交通大學<br>電信研究所<br>85<br>In this thesis, we proposed a bursty DQPSK demodulator which can be used in HFC system uplink. The key component of the demodulator, burst timing recovery, is implemented as a clock phase correlator. The advantages of the clock phase correlator are short acquisition time and minimum jitter. The function of clock phase correlator was verified in a system simulation. The demodulator was implemented using FPGA. Finally, by using commercial QPSK modem c
