Bangladesh University of Business and Technology or BUBT is a private university located in Mirpur, Dhaka, Bangladesh. The university was established under the Private University Act 1992. BUBT is regulated by the University Grants Commission Bangladesh.BUBT was founded in 2003 under the authority of the Private University Act and was approved by the University Grants Commission and the Ministry of Education, Government of Bangladesh. It was modeled after North American universities. It started its operation in the Dhaka Commerce College campus, the founder organization of BUBT. It is running its programs in its own campus at Rupnagar R/A, Mirpur. Classes are also held at Dhaka Commerce College campus. In 2011 UGC has ranked BUBT as one of the best eight private universities. Around 1000 students were awarded with their graduate and post graduate degrees in the first convocation this year .BUBT is the proud member of Association of Commonwealth Universities. Wikipedia.

E-Health is one of the solutions to provide better access for patients and physician to healthcare facilities. In developing countries, e-Health is particularly important due to a shortage of physician and medical workers. Although most physicians in developing countries like Bangladesh acknowledge the benefits of e-Health, low adoption is not uncommon. The objective of this study is to identify the critical factors affecting e-Health adoption among physicians in Bangladesh. A cross-sectional survey questionnaire method was used for this study. The structural equation modeling (SEM) with the partial least square (PLS) approach was used to analyze the data. The study found that Performance Expectancy, Effort Expectancy, Social Influence and Personal Innovativeness had a significant impact on the behavioral intention to use e-Health, while Facilitating Conditions had no significant effect. The findings of this study will facilitate the degree of more acceptance of new technology by the physicians for their own betterment. Copyright © 2016, IGI Global.

In this study we extend the Hadamard's type inequalities for convex functions defined on the minimum modulus of integral functions in complex field. Firstly, using the Principal of minimum modulus theorem we derive that m (r) is continuous and decreasing function in R+. Secondly, we introduce a function t (r) and derived that t (r) and lnt (r) are continuous and convex in R+. Finally we derive two inequalities analogous to well known Hadamard's inequality by using elementary analysis. © Maxwell Scientific Organization, 2014. Source

Density based clustering algorithms are one of the primary method for data mining. The clusters which are formed using density clustering are easy to understand and it does limit itself to shapes of clusters. Existing density based algorithms have trouble because they are not capable of finding out all meaningful clusters whenever the density is so much varied. VDBSCAN is introduced to compensate this problem. It is same as DBSCAN (Density Based Spatial Clustering of Applications with Noise) but only the difference is VDBSCAN selects several values of parameter Eps for different densities according to k-dist plot. The problem is the value of parameter k in k-dist plot is user defined. This paper introduces a new method to find out the value of parameter k automatically based on the characteristics of the datasets. In this method we consider spatial distance from a point to all others points in the datasets. The proposed method has potential to find out optimal value for parameter k .In this paper a synthetic database with two dimensional data is used for demonstration. ©2010 IEEE. Source

A precise theoretical investigation has been made on the cylindrical and spherical (nonplanar) Gardner solitons (GSs) and double layers (DLs) in a dusty electronegative plasma (composed of inertial positive and negative ions, Maxwellian cold electrons, non-thermal hot electrons, and negatively charged static dust). The reductive perturbation method has been used in derivation of the modified Gardner (MG) equation describing the nonlinear propagation of the dust ion-acoustic (DIA) waves. The MG equation admits solitary waves (SWs) and DLs solutions for σ around its critical value σc (where σc is the value of σ corresponding to the vanishing of the nonlinear coefficient of the Korteweg de-Vries (K-dV) equation). The nonplanar SWs and DLs solutions are numerically analyzed and the parametric regimes for the existence of the positive as well as negative SWs and negative DLs are obtained. The basic features of nonplanar DIA SWs and DLs, which are found to be different from planar ones, are also identified. The implications of our results to different space and laboratory dusty plasma situations, are discussed. © 2013 Chinese Physical Society and IOP Publishing Ltd. Source

Dust-acoustic (DA) solitary structures and their multi-dimensional instability in a magnetized dusty plasma (containing inertial negatively and positively charged dust particles, and Boltzmann electrons and ions) have been theoretically investigated by the reductive perturbation method, and the small-k perturbation expansion technique. It has been found that the basic features (polarity, speed, height, thickness, etc.) of such DA solitary structures, and their multi-dimensional instability criterion or growth rate are significantly modified by the presence of opposite polarity dust particles and external magnetic field. The implications of our results in space and laboratory dusty plasma systems have been briefly discussed. © 2012 American Institute of Physics. Source
