Abstract:

In Refs. [1, 2], the deterministic theory of drift of single-domain ferromagnetic nanoparticles in viscous fluids, which occurs due to the Magnus effect, has recently been developed and numerically confirmed. Here, we present analytical and numerical results obtained within the stochastic theory on the influence of temperature on the drift velocity.

Abstract:

<p>The effect of water temperature prey capture success and foraging behavior of drift-feeding juvenile brown trout (<em>Salmo trutta</em>) was examined in a laboratory stream. Water temperature treatments were 5.7, 6.7, 8.0, 10, 12 and 14°C. Five wild brown trout, age 1+ and collected by electrofishing from a stream in Western Sweden, were used in the experiments. There was a significant effect of water temperature on both prey capture probability and the percentage of time spent resting on the substrate while drift-feeding. At low water temperatures the fish suffered a reduced prey capture c

Abstract:

Speed, power and reliability of analogue integrated circuits (IC) exhibit temperature dependency through the modulation of one or several of the following variables: band gap energy of the semiconductor, mobility, carrier diffusion, current density, threshold voltage, interconnect resistance, and variability in passive components. Some of the adverse effects of temperature variations are observed in current and voltage reference circuits, and frequency drift in oscillators. Thermal instability of a voltage-controlled oscillator (VCO) is a critical design factor for radio frequency ICs, such as

Abstract:

Winter conditions are believed to play an important role in the population dynamics of northern temperate stream fish, challenging the ability of fish to physiologically and behaviourally adapt. Climate change is predicted to increase both mean temperature and temperature fluctuations, especially during winter, leading to dynamic environmental conditions in terms of river ice production and flow. Therefore, knowledge about the winter ecology of stream fish is important for predicting and mitigating anthropogenic impacts on fish production in boreal streams.

Abstract:

Model ceria catalysts were evaluated for NOx storage and desorption performance under lean conditions. Three different storage temperatures (80 °C, 120 °C, and 160 °C) were utilized to evaluate NOx storage. Higher temperatures resulted in higher NOx storage. It was observed that storage of platinum promoted ceria resulted in higher NOx storage compared to promotion with palladium. NOx desorption behavior of platinum promoted ceria indicated that the majority of NOx is released at high temperatures (> 350 °C), comparatively palladium promotion released more of the stored NOx at lower temperatur

It has potential advantages over conventional ion selective electrodes in their small size, rapid response, high input impedance and low output impedance. It is extremely attractive for biomedical applications. The ion-sensing membrane plays an important role because the pH response of ISFET device is determined by sensing membrane. In the thesis, the hydrogenated amorphous silicon (a-Si:H) and amorphous tungsten oxide (a-WO3) thin films were used as the sensing membra

碩士<br>明新科技大學<br>電子工程系碩士班<br>105<br>Insulated Gate Bipolar Transistor (IGBT) has the merits of both high input impedance contributed from the Metal-Oxide-Silicon Field Effect Transistor (MOSFET) structure and high current gain contributed from the Bipolar Junction Transistor (BJT) structure. The power discrete can also tolerate high breakdown voltage making itself indispensable. In this paper, that different processes leading to different structures, such as junction depth, cause various depletion regions corresponding to different breakdown voltages is under study. It shall be intriguing to me

Seit Juli 2004 wird an der Außenstelle Collm der Universität Leipzig kontinuierlich ein Meteorradar zur Messung des Windes und der Temperatur im Höhenbereich 80-100 km betrieben. Die Messungen dienen der Überwachung der Dynamik der Mesopausenregion, und ihrer Änderungen auf Zeitskalen von Tagen und Jahren. Erste Ergebnisse vom Herbst 2004 werden dargestellt, verglichen mit den ebenfalls am Collm durchgeführten Langewellenreflexionswindmessungen. Die Ergebnisse zeigen, dass die vertikale Struktur des Windsystems und die Variationen von Tag zu Tag qualitativ übereinstimmen. Die mit dem Meteorrad

碩士<br>國立雲林科技大學<br>電子與資訊工程技術研究所<br>86<br>In this thesis, it emphasizes on the study of the ion sensitive field effect transistor (ISFET). Due to the fact that the a-Ta2O5 material was studied in detail in the related papers and suited to compare with other pH-sensitive thin films, the amorphous tantalum pentoxide (a-Ta2O5) materials will be used. According to the related papers, the hydrogenated amorphous silicon (a-Si:H) material was never published before, we will first choose a-Si:H as pH-sensitive materials. Because the characteristics of ISFET consisting of the temperature, hysteresis an

Abstract:

In the past decades, numerous single-molecule techniques have been developed to investigate individual bio-molecules and cellular machines. While a lot is known about the structure, localization, and interaction partners of such molecules, much less is known about their mechanical properties. To investigate the weak, non-covalent interactions that give rise to the mechanics of and between proteins, an instrument capable of resolving sub-nanometer displacements and piconewton forces is necessary. One of the most prominent biophysical tool with such capabilities is an optical tweezers. Optical t

Abstract:

A cryogenic (325-80 K) ion mobility-mass spectrometer was designed and constructed in order to improve the analytical figures-of-merit for the chemical analysis of small mass analytes using ion mobility-mass spectrometry. The instrument incorporates an electron ionization source, a quadrupole mass spectrometer, a uniform field drift cell spectrometer encased in a cryogenic envelope, and an orthogonal geometry time-of-flight mass spectrometer. The analytical benefits of low temperature ion mobility are discussed in terms of enhanced separation ability, ion selectivity and sensitivity. The disti

Abstract:

Organic semiconductors are a new key technology for large-area and flexible thin-film electronics. They are deposited as thin films (sub-nanometer to micrometer) on large-area substrates. The technologically most advanced applications are organic light emitting diodes (OLEDs) and organic photovoltaics (OPV). For the improvement of performance and efficiency, correct modeling of the electronic processes in the devices is essential. Reliable characterization and validation of the electronic properties of the materials is simultaneously required for the successful optimization of devices. Further
