No full textThis thesis is submitted to the Department of Electrical and Electronic Engineering, Khulna University of Engineering & Technology in partial fulfillment of the requirements for the degree of Master of Science in Electrical and Electronic Engineering, July 2017.Cataloged from PDF Version of Thesis.Includes bibliographical references (pages 51-58).Device scaling is the key factor that drives the microelectronics revolution as
described by Moore’s law. Reduction of the physical MOS device dimensions has been
proved beneficial in terms of circuit speed, cost and power consumption. But the continued
miniaturization of the MOS transistor imposes a lot of challenges in terms of device design.
Addressing to this issue “Compound semiconductor-on-insulator” was reported in 2010,
which is also termed as XOI. III-V materials can be considered as the perfect replacement of
silicon as the channel material in MOS devices due to their excellent transport properties. It is
well established that the capacitance – voltage (C-V) measurement is widely accepted
technique for different device parameter extraction and also to measure the interface quality
of a fabricated MOSFET. An analytical model is developed here using quantum mechanical
approach to explain the C-V characteristics of XOI FET by solving coupled Schrodinger-
Poisson equation. It is found that the energy quantization effect in such short channel device
causes a unique staircase nature in the C-V characteristics for channel thickness up to 20nm.
Beyond that this nature disappear reproducing traditional C-V characteristics of SOI FET. It
is also seen that channel thickness and dopant impurity has an impact on the shift of C-V
curve. The threshold voltage of such devices is found higher at reduced channel thickness.Muhammad Mainul IslamMaster of Science in Electrical and Electronic Engineerin

Mechanical properties of flax fiber‐reinforced composites at different relative humidities: Experimental, geometric, and displacement potential function approaches
No full textDue to the good mechanical properties, flax fiber-reinforced epoxy composites are being widely used as a green alternative to glass fiber composites. However, plant fibers absorb moisture from the environment, being in a higher moisture uptake as the relative humidity (RH) increases. This absorbed moisture deteriorates the mechanical properties of the composites. In this study, geometric and displacement potential function (DPF) approaches are used to predict the mechanical properties of flax fiber-reinforced epoxy composites under environmental conditions, in particular, different RH values. The tensile properties that were measured experimentally strongly agreed with the analytical findings. Almost similar results were found for the tensile strain those were measured experimentally and the one predicted by the geometric function. However, the predicted strain values were 38% and 42% less than the experimental ones for 0% and 95% RH conditioned composites, respectively, when DPF was used. Good conformity between the experimental, analytical, and DPF formulation for predicting mechanical properties ensures the practical applicability of this study. The formulations established in this work could, therefore, be utilized to analytically solve laminated composites under specific boundary conditions in structural applications.Fil: Moudood, Abdul.

Bid-winning potential optimization for concession schemes with imprecise investment parameters
No full textThis paper portrays the development of a concession-investment optimization model for optimizing the winning potential of a concession-bid from the prospective promoters' viewpoints by taking into account imprecise investment parameters. A financial performance measure has been developed to quantify bid-winning potential. Fuzzy set theory is embedded into a genetic algorithm to optimize bid-winning prospects of concession schemes under uncertainty. The fuzzy vertex method accomplishes propagation of uncertainty in cash flows arising from imprecision in estimation of investment parameters. Genetic algorithm solves the optimization routine. The developed model yields global near-optimal solution of bid-winning potential with contributing values of concessionary items: concession length, base price, and equity level under uncertain investment environment. A numerical example demonstrates model capabilities. The model results would help promoters devise a profitable, yet competitive, financial proposal.Griffith Sciences, Griffith School of EngineeringNo Full Tex
