Measurement and Simulation of Mosfet Device Parameters

Knowing the current-voltage (I-V) characteristics of MOSFETs used as switching devices is very important in circuit designs where detailed specifications are needed. Therefore, preapplication simulation is very important. Simulation of power electronic devices can be done with MATLAB, PSpice and LTSpice software packages. In this study we measured a commercial MOSFET devices and compared with the LTSpice and MATLAB/Simulink simulation. Two-channel power supply, which can be controlled by a PC or a GPIB, is required to measure the I-V characteristics of MOSFET devices. We measured the MOSFET with a Keithley 2634B Power Supply. The MOSFET measurements were limited to ±20.2V at ±1.5A maximum or ±202V at ±100mA maximum per channel by the power supply. It is found that good agreements observed between measurement and simulations in output and transfer characteristics.
DEVELOPMENT AND CHARACTERIZATION OF LOVASTATIN LOADED MICROSPHERES

In this study, the use of biodegradable polymers for microencapsulation of Lovastatin using solvent evaporation technique was investigated. Ethyl Cellulose and Eudragit L100 was selected as a retardant polymer because of its advantages over other biodegradable polymers. Eight different batches of microspheres were prepared by varying the concentration of polymer. The microspheres were characterized for drug content, percentage yield and encapsulation efficiency, particle size analysis and surface morphology. Microsphere prepared with low drug content produces higher percentage yield and encapsulation efficiency values. It was observed the increase in concentration of the polymer, increases the mean particle size of the microspheres. The effect of polymer concentration on the in vitro release of Lovastatin from the microspheres was also studied. It can be seen that by increasing the polymer concentration, decreases the rate of drug release from the microspheres dramatically. The kinetics of drug release from F1 microspheres predominantly follows Higuchi pattern followed by zero order. The release kinetics of F3 and F4 predominantly follows zero order followed by Higuchi and then first order.
Burning Off of Carbon Deposit Removal at Stagnant Boundary Layer

Burning off is the main method of carbon deposit removal from coke oven chambers. The heterogeneous reaction must be considered when the air blowing eliminates wall polycarbonate in the coke oven. In the three-dimensional problem of the burning off in the coke oven, the turbulent flow is induced by the interaction of the forced convection form the air inlet and natural convection from the high temperatures on the wall. This paper intends to show that the models can be generated by the solution of equations of conservation of mass, energy and spices in the boundary layer while lumping at the surface all the intraparticle effects. In order to understand the Sorect effect, there were three cases comparison. From the results, the Sorect effect is not clear, and P1 model has highly nonphysical behavior together with numerical instabilities inherent to the model. © 2013 The Authors.

This Project presents the modified coupled-inductor single-stage boost inverter (CL-SSBI)-based grid-connected photovoltaic (PV) system. The transformer can be used in line or high frequency, but the linefrequency transformer has large size and weight. The high-frequency transformer is used in PV systems decreasing the efficiency and making the system more complex. This project is to design a transformerless inverter connected to photo voltaic system, so that to design costless PV system using coupled inductor single phase inverter. To maintain the advantages ofthe impedance network, only a diode is added in the front of the original topology, to block the leakage current loop during the active vectors and open-zero vectors. Simultaneously, the leakage current caused by other transitions can also be reduced due to the fact that the magnitude of common-mode voltages is reduced. Experimental results of the transformer less PV system are presented in two cases modified CL-SSBI modulated by maximum constant boost (MCB) control method and PWM. Experimental results for both CLSSBI topology modulated by the MCB control method and modified CLSSBI topology modulated by PWM are also obtained.
Validating and Supporting a Continuous Ex- perimentation Development Environment

The number of conducted A/B tests is growing throughout companies in software development. Many of these companies develop their own in-house Experimentation Platform to support these experiments. In this thesis we identify factors that influence the trustworthiness and soundness of A/B tests by conducting a literature review. We discuss nineteen influential factors categorised as essentials and pitfalls. Using the data of 268 experiments from ING we verify the trustworthiness of ING’s own Experiment Platform, and conclude that there is room for improvement. Finally, we provide a method for developers and engineers to consider these factors during the experimentation phase by modelling them into a questionnaire containing 67 questions. These questions are grouped into three categories, which are referred to as the three A’s of A/B Test validation: Availability, Analysability and Accuracy. To help administer this questionnaire we introduce the first Open-Source toolkit for this matter: ABvalidator.
A Micro Data Approach to the Identification of Credit Crunches

This paper presents a micro data approach to the identification of credit crunches. Using a survey among German firms which regularly queries the firms’ assessment of the current willingness of banks to extend credit we estimate the probability of a restrictive credit supply policy by time taking into account the creditworthiness of borrowers. Creditworthiness is approximated by firm–specific factors, e.g. the firms’ assessment of their current business situation and their business expectations. After controlling for the banks’ refinancing costs, which are also likely to affect the supply of loans, we derive a credit crunch indicator, which measures that part of the shift in the willingness to lend that is neither explained by firm-specific factors nor by refinancing costs.

An investigation into stereo algorithms: An emphasis on local-matching

Stereo vision attempts to reconstruct the 3D structure of a scene given two images. The main difficulty with stereo vision is the correspondence problem. Localmatching stereo algorithms are an attractive solution to this problem because they have a uniform structure and can be paralellized. This makes them applicable in real-time systems because they can be implemented on graphics processing units (GPUs) and field programmable gate arrays (FPGAs). This thesis closely analyses local-matching algorithms and explores two issues. The first issue is that of using temporal seeding in stereo image sequences. In a stereo image sequence, finding feature correspondences is normally done for every frame without taking temporal information into account. Reusing previous computations can add valuable information. A temporal seeding technique is developed for reusing computed disparity estimates on features in a stereo image sequence to constrain the disparity search range. Features are detected on a left image and their disparity estimates are computed using a local-matching algorithm. The features are then tracked to a successive left image of the sequence and by using the previously calculated disparity estimates, the disparity search range is constrained. Errors between the local-matching and the temporal seeding algorithms are analysed on a short and long dataset. Results show that although temporal seeding suffers from error propagation, a decrease in computational time of approximately 20% is obtained when it is applied on 87 frames of a stereo sequence. The second issue is that of developing a confidence measure for local-matching stereo algorithms. A confidence measure is developed and applied to individual disparity estimates in local-matching stereo correspondence algorithms. It aims at identifying textureless areas, where most local-matching algorithms fail. The confidence measure works by analyzing the correlation curve produced during the matching process. The measure is tested by developing an easily parallelized local-matching algorithm, and is used to filter out unreliable disparity estimates. Using the Middlebury dataset and the developed evaluation scheme, the results show that the confidence measure significantly decreases the disparity estimate errors at a low computational overhead. Furthermore, the confidence measure is used to improve start-up disparities in temporal seeding. Results show that the measure does not succeed in filtering out features producing high errors.
OBJECT-BASED APPROACH FOR CROP ROW CHARACTERIZATION IN UAV IMAGES FOR SITE-SPECIFIC WEED MANAGEMENT

A list of color-infrared images captured from the new generation of remote platforms known as unmanned aerial vehicles (UAV), specifically a quadrotor, was tested for site-specific weed management applications. The aim was to identify and classify the crop rows within a maize crop-field, with the ultimate objective of distinguishing small weed seedlings at early stages for in-season sitespecific herbicide treatment. An object-based image analysis (OBIA) procedure was developed by combining several scene, contextual, hierarchical and object-based features in a looping structure. The procedure integrates several features from the crop-field patterns: 1) field structure, such as field limits and row length, 2) crop patterns, such as row orientation and inter-row distance, and 3) plant (crop and weeds) characteristics, such as spectral properties (NDVI values) and plant dimensions; as well as 4) hierarchical relationships based on different segmentation scales, and 5) neighboring relationships based on distance, position and angle between objects. The algorithm identified and counted the rows with 100% accuracy in most of the images and the definition of the longitudinal border of the crop rows was successful with 90% of overall accuracy, comparing to on-ground measures of weed emergence.
Chapter 2 Physics of the Tunable Ferroelectric Devices

This chapter gives an introduction to those aspects of the theory of ferroelectricity that a microwave engineer needs for understanding the physics behind tunable microwave devices. In spite of the simplicity the provided theory is quite useful for designing microwave devices and the interpretation of the experimental results. The crystalline structure of the displacive perovskite ferroelectrics, the DC field dependent dielectric permittivity and loss tangent are in the focus. The dynamic nonlinearity and acoustic properties are also considered.

Information adoption from online review sites for decision-making

This study explored the common phenomenon of using online review sites to acquire information for decisionmaking. Nowadays, online review sites such as Yelp in the US and OpenRice in Hong Kong are gaining popularity for consumers to share their post-purchase experiences. Based on the elaboration likelihood model (ELM) and social influence theory (SIT), we investigate how participating in online review sites influences consumers’ purchase decisions. Our population comprises consumers who are users of OpenRice. To test our model, we collected 316 valid questionnaires with a response rate of 30%. We find that the source credibility and argument quality of a review, and the reader’s perceived informational social influence and normative social influence have significant effects on information adoption for decision-making.
A RATE COMPATIBLE PUNCTURED TURBO (RCPT) CODES MAP ASSISTED BIT SYNCHRONISATION SCHEME

In this paper we propose a Rate Compatible Punctured Turbo (RCPT) codes MAP Assisted Bit Synchronisation (MABS) scheme, which is a combination of Code Assisted Bit Synchronisation (CABS) scheme employing MAP algorithm with BPSK modulation and incorporating RCPT Codes. Simulation results shows that the proposed scheme employing turbo codes is comparable to the perfect timing coherent system in addition providing synchronisation. RCPT codes analyses the MABS schemes at different rates and in this work an optimum decoder is used.
ECO-TRANSFORMATION AND ELECTROCUTION. A MAJOR CONCERN FOR THE DECLINE IN VULTURE POPULATION IN AND AROUND JODHPUR

Vultures are large sized birds with late maturity and a low reproductive output, making populations especially vulnerable to adult mortality caused by environmental and anthropogenic perturbations. During the last few decades the Thar witnessed tremendous human activities, because of an increase in population. It underwent phenomenal ecotransformations, with dry land turning in to wet in several parts of the Thar Desert. The increase in population within this region generated several new challenges for the habits of vultures. The findings of the current investigation suggest that changes in the traditional cattle treatment pattern, the increase in the feral dogs population, the presence of high tension electricity poles near to dumping sites, the unavailability of food and water and the opening of a carcass waste management treatment plant were causes that adversely affected the biodiversity of vultures in the area under investigation.
ACCURACY OF SHORT TERM WIND POWER PREDICTIONS DEPENDING ON METEOROLOGICAL CONDITIONS

Short term wind power predictions should provide two types of information: The expected power output of wind turbines and the expected uncertainty of this prediction. So far, the uncertainty is commonly given by annual averages such as the root mean square error. But the prediction error depends on the complexity of the prevailing meteorological situation and, therefore, should be newly assessed for each individual prediction. We investigate the impact of meteorological conditions on the prediction accuracy. As a first approach we consider the wind speed and find that the uncertainty of the wind speed prediction does only weakly depend on the magnitude of the predicted wind speed. Moreover, we derive a method to model the uncertainty of a specific power prediction in terms of the power curve and the mean error of the underlying wind speed prediction. Using an existing weather classification scheme we relate the prediction error of the wind speed to the overall weather situation. While for a number of sites the prediction uncertainty is significantly lower in weather conditions dominated by high pressure than in low pressure situations other sites do not show this effect.

Moments model for a continuous sorbet crystallization process

Freezing is an important step in the manufacturing process of ice-cream and sorbet, since the operating conditions have a strong influence on the micro-structure, and consequently on the sensorial attributes of the final product. This paper presents a model for a continuous sorbet crystallization process approach based on the moments model approach and its validation with experimental data. The moments model was used to characterize the influence of the operating conditions during sorbet freezing such as: the evaporation temperature of the refrigerant fluid, the mix flow rate and the dasher rotation speed, on the final product characteristics such as: ice crystal size and draw temperature. The moments model includes heterogeneous nucleation and growth phenomena, has low computational requirements and is quite adapted for optimization or process control tasks.
ELECTRON-DEPENDENT COMPETITION BETWEEN PLASTOQUINONE AND INHIBITORS FOR BINDING TO PHOTOSYSTEM II

Photosystem II (PS II) of green plants oxidizes water and reduces plastoquinone (PQ). The reduction of 1 PQ molecule requires 2 consecutive photoreactions of a PS II center and involves 2 bound PQ molecules. The ‘primary’ PQ molecule Q is reduced photochemically to the semiquinone state Qand it in turn reduces a ‘secondary’ PQ molecule R to the semiquinone state R-. When Q is photo-reduced a second time, it reduces Rto the fully reduced plastoquinol state RN,; protons are taken up in this process also, in a manner that is still unclear [l-3]. It was originally assumed that R was a permanent component of PS II. However, I have proposed that, except while semireduced, it exchanges rapidly (>50 s-l) with freePQ(HJ diffusing in the membrane [4]. By implying that its binding site is frequently left vacant, this view suggests a simple hypothesis for the mechanism by which a variety of compounds prevent PQ reduction, i.e., that the binding of PQ and of inhibitor (I) to PS II centers with vacant secondary PQ binding sites (PS II,) are competitive reactions:
A Cytokine Odyssey: From Interleukin-2 Signaling to Cytokine Therapy for Cancer

Howard (Department of Biochemistry and Microbiology) Departmental Member Dr. Juan Ausio (Department of Biochemistry and Microbiology) Departmental Member Dr. Ben F. Koop (Department of Biology) Outside Member T cells are a crucial component of the immune system and play an important role in responses to pathogens, tumours, and transplanted tissues. In many human cancers, elevated numbers of tumour-infiltrating CD8+ killer T cells are associated with favourable outcomes, suggesting that enhancing T-cell responses could provide major therapeutic benefit for cancer patients. Thus, identifying factors that can promote protective T-cell responses is of great clinical importance. The cytokine interleukin-2 (IL2) is a major inducer of T-cell proliferation and differentiation, and is used clinically to treat melanoma and renal cell carcinoma. The first two chapters of this thesis focus on the biochemical mechanisms by which IL-2 induces T-cell proliferation. By using mutant and chimeric cytokine receptors expressed in lymphocyte cell lines, the interplay between Shc and STAT5, two major mitogenic signaling pathways activated by the IL-2 receptor, are investigated, revealing an essential synergy between the two pathways for optimal lymphocyte proliferation.
Seine Vision Resolving the Mysteries of the Halstead Measures

The Halstead measures are still a subject of mystery. The properties of these measures are not well understood and there is still a confusion of the scales (types). Halstead’s measures are used by many tools, but the usefulness and the meaning of the numbers of these measures are not clear. We use the concept of the extensive structure from measurement theory in order to investigate and resolve the mysteries of the Halstead measures.
CVD Diamond Vacuum Window for Synchrotron Radiation Beamlines

An innovative design of a chemical vapour deposited (CVD) diamond vacuum window is presented. The thermo-mechanical properties of the integrated window have been optimised through extensive numerical modelling. An innovative brazing procedure suited for thin non-metallised windows was concurrently developed. Mechanical and optical tests performed on the prototype of the window confirmed the validity of the adopted concepts, thus providing proof that the developed solution constitutes a valid and in many aspects advantageous solution with respect to beryllium windows so far used at synchrotron radiation facilities for this purpose. Based on the proposed design, an off-the-shelf diamond window is being brought to market.

PARTICLE-IN-CELL SIMULATIONS ON ANTENNA CHARACTERISTICS IN MAGNETIZED PLASMA

We for the first time applied electromagnetic PIC (Particle-In-Cell) computer simulations to analyze the antenna characteristics in magnetized plasma. In a three-dimensional simulation space, we placed a dipole antenna which is a conducting current line in a magnetized plasma. By providing a Gaussian pulse as an input power to the center of the antenna and observing the current induced at the power feeding point, we obtain the input impedance of the antenna as a function of frequency. We particularly examined the electron kinetic effects on the antenna impedance such as electron temperature and electron evacuated region (ion sheath) formed around the antenna. It is confirmed that the most obvious resonance point is the local Upper Hybrid Resonance frequency. As the electron temperature increases, the resonance frequency also increases in accordance with the modification of dispersion relation for the UHR branch. We also examined the antenna impedance variation by changing the size of the electron evacuated region or ion sheath created around the antenna. We could confirm that the antenna resonance near the local UHR frequency is sharp for the small sheath while the profiles of the impedance approach to those of vacuum case as the sheath becomes large. The resonance frequency also decreases because the plasma density also decreases in the vicinity of the antenna.
