Abstract:

För att erhålla mjukare växlingsförlopp och samtidigt få lång livslängd på våta kopplingar i automatväxellådor krävs förbättrad konstruktion. För att förbättra konstruktionen behövs mer kunskap om inkopplingsförloppet av våta kopplingar. En testrigg för att undersöka inkopplingsförloppet har byggts. Driftsparametrar och inkopplingskarakteristik efterliknar förhållanden i en verklig automatväxellåda. I apparaten kan hastighet, drivmoment, tröghet, pålastningshastighet och oljetillförsel varieras. Normalkraft, bromsmoment, glidhastighet och temperatur mäts som funktion av tiden. Experimentella s

Nocturnal low-level inversion events occurred throughout the year in 68% of the 0400h PST radiosonde ascents. Afternoon (1600h PST) inversion events, in contrast, were primarily a winter phenomena, limited to 24% of the readings between October and March, and were deepest and strongest during the winter months.

Abstract:

This study addresses the need for investigation of drying-rate characteristics of fine-grain soils. The research was an attempt to develop a parameter for use in thermal consolidation and/or shrinkage modeling. The investigation required the development of new test methods. During the study, a strong correlation between plasticity indices and certain drying characteristics was noted and discussed in detail. An argument is presented for the superiority of the Drying-Rate Test in comparison with current laboratory procedures for determining Atterberg Limits.

This study examines the spatial and temporal characteristics of the surface air temperature in Portland, Oregon. Spatial temperature patterns indicate that the dominant control factors on seasonal temperature distribution are local topography, elevation, and urban-rural differences in surface structure. A heat island exists in the Portland area; the intensity of the heat island rang€s from 4° to 10° F, and varies throughout the year. The strongest heat island is found in the July minimum temperature. Temperature distribution in Portland and the adjacent area is affected by winds and rainy cond

The development of sensing devices is one of the instrumentation fields that has grown rapidly in the last decade. Corresponding to the swift advance in the development of microelectronic sensors, optical fibre sensors are widely investigated because of their advantageous properties over the electronics sensors such as their wavelength multiplexing capability and high sensitivity to temperature, pressure, strain, vibration and acoustic emission. Moreover, optical fibre sensors are more attractive than the electronics sensors as they can perform distributed sensing, in terms of covering a reaso

碩士<br>國立中興大學<br>生命科學系<br>92<br>Abstract In order to understand the effects of irradiance and temperature on the chlorophyll fluorescence characteristics among plant species, 3 varieties of sweet potato with different leaf color (yellow, green and purple), and 17 species of tropical origin as well as 9 species of temperate origin plants were used as materials. The results indicated that yellow sweet potato showed lower chlorophyll (chl) content and higher chl a/b ratio in leaves. When merged together the results measured from 3 sweet potato leaves to statistical analysi

碩士<br>崑山科技大學<br>光電工程研究所<br>98<br>In this thesis, ZnO nanorods were synthesized on the glass substrates in a solution of Zn(NO3)2．6H2O and HTMA at 90℃ The morphologies and microstructures of the ZnO films and nanorods are characterized by X-ray diffraction (XRD) patterns, atomic force microscopy (AFM), scanning electron microscopy (SEM), and photoluminescence (PL). First, the ZnO seed layer was deposited on glass structure by the RF sputtering system to study the effect of ZnO nanorods. The effects of different annealing temperature on the seed layer growth have been investigated in this stud

碩士<br>國立交通大學<br>光電工程學系<br>99<br>In this thesis, we demonstrated metal-coated GaN nanocavity laser operable at room temperature by optical pumping. We first utilized fabrication process to define the nanostripe pattern on undoped GaN layer grown on a sapphire substrate, with a thin dielectric layer and aluminum layer coated on it. From micro-photoluminescence measurement result, we observed a single mode lasing at room temperature with lasing wavelength around 370nm and the quality factor was about 150. Moreover, by simulation analysis, we proved the aluminum layer coated on the nanostripe stro

Based on generation III pressurized light water reactor, the design of AP1000 changes the safety system into passive type. The advantages of passive safety system are no longer needs power to motivate the emergency core cool down devices, and reduces the chance of human mistakes during operating. Although AP1000 is designed by the passive co

On the other hand, under the circumstances of the global warming and the global change, sea surface temperature is a major indicator of weather variation and long-term climate change. In this thesis, Extended Reconstructed Sea Surface Temperature version 4 (ERSST), Advanced Very High Resolution Radiometer Sea Surface Temperature (AVHRR SST) and Ocean Heat Content (OHC) data supplied from National Oceanic and Atmospheric Administration are applied. ERSST represents the late century’s trend, AVHRR SST repr
