A new approach on the torison and curvature tensors in supermanifolds
(BRAC University, 2005)In this paper geometric space, super space, supermanifold, superconnection, the torsion and the curvature tensors are studied and some new notions of local forms of the torsion and curvature tensors are established, for ... -
A new technique of PWM boost inverter for solar home application
(BRAC University, 2007)This paper analyzes the procedural approach and benefits of applying optimization techniques to the design of a boost dc-ac converter with solar cell as an input. The analysis is performed based on the particular 12V DC ... -
Nonparametric bootstrapping for multiple logistic regression model using R
(BRAC University, 2004)The use of explanatory variables or covariates in a regression model is an important way to represent heterogeneity in a population. Again bootstrapping is rapidly becoming a popular tool to apply in a broad range of ... -
A note on the choice of the smoothing parameter in the kernel dinsity estimate
(BRAC University, 2009)Among different density estimation procedures, the kernel density estimation has attracted the most attention. In this paper, the choices for smoothing parameter is discussed when the widely used Gaussian kernel is used ... -
The notion of women as bearers of culture in Monica Ali's Brick Lane
(BRAC University, 2010)Alistair Cormack (2006) describes Brick Lane as a 'post-colonial story' with a 'realist narrative'; to a post-colonial critic, this has many implications. Yet looking at this text from a feminist point of view has many ... -
Numerical approximation of a nonlinear parabolic partial differential equation
(BRAC University, 2008)We consider the Allen-Cahn model of phase transitions. We approximate the problem using finite difference method in space coupled with several explicit and implicit methods in time and compare the solutions. We present ... -
Occurrences of corrosion: causes and prevention
(BRAC University, 2006)Corrosion of metal is a ubiquitous phenomenon that occurs in various forms. Atmospheric or uniform, galvanic, crevice, pitting, and microbial corrosion are most familiar forms of corrosion. This note briefly demonstrates ... -
On gamma-ray emission from pulsar magnetosphere
(BRAC University, 2007)Pulsars, a class of rotating neutron stars, are one of the most interesting objects of nature. Although most pulsars have been detected in the radio range, a handful of them are active in gamma rays. In recent years, ... -
On Terahertz laser pulse propagation in negative index metamaterials
(BRAC University, 2013)The nonlinear propagation of a terahertz laser pulse propagation in the resonant region of a negative index meta-material is investigated. The resonant frequency of a split ring resonator (SRR), comprosing the negative ... -
Organizational citizenship behavior: Its nature and antecedents
(BRAC University, 2004)Theory and research on Organizational Citizenship Behaviors (OCB) has presumed OCB as a set of desirable behaviors that contributes to the organizational effectiveness. So far OCB has been connoted as one of the antecedents ... -
