The purpose of the paper is to discuss a comparative evaluation of performance of two different controllers i.e. Proportional-Derivative Controller (PD) and Linear Quadratic Regulation (LQR) in Quadrotor dynamic system that is under-actuated with high nonlinearity. As only four states can be controlled at the same time in the Quadrotor, the traject

The characteristics of laminar separation bubbles (LSBs) on the SD 7003 airfoil have been extensively studied in the past at low Reynolds numbers. It has been found that the LSB is extensive, especially at airfoil at angle of attack (α) of 4º. To analyze separation, transition and reattachment of flow around SD 7003 airfoil effectively, Computati

In anaerobic digestion for enhancement of biogas production, various types of pre-treatment method have been used with some limitations in terms of sustainable environmental management. Although acid and alkali pretreatment have a significant effect on the degradation of biomass, these methods have some negative impacts on the environment due to th

The ancient maritime trading links enabled by the seasonal monsoons between East Africa and China, via the Arabian, Indian and Southeast Asian ports, have played an important but overlooked role in the history of human civilization. The coastal regions of the Indian Ocean represent a cosmopolitan blend of social and cultural diversity enriched main

Muslim presence was manifest in the coastal regions of Southern India from the earliest days of Islam, as evidenced by the establishment of Arab trading settlements, with minor political impact prior to the conquests in Northern India from the beginning of the 8th century, which solidified the influence of Islam leading to tangible political and so

This paper investigates the dynamics and control of a quadcopter using the Model Predictive Control (MPC) approach. The dynamic model is of high fidelity and nonlinear, with six degrees of freedom that include disturbances and model uncertainties. The control approach is developed based on MPC to track different reference trajectories ranging from

The SD 7003 has been investigated quite extensively in the past at different Reynolds numbers. At moderate Reynolds numbers and low angles of attack its upper surface is dominated by a large laminar separation bubble which provides a demanding test case for RANS-based transition models. In this article, a widely used open-source Computational Fluid

Over the last three decades, managers, researchers, practitioners, management consultants and many other people have used the Analytic Hierarchy Process (AHP) to make decisions or to prioritize a set of factors in many areas of management. Perhaps, the most appealing reason for the method’s widespread use is its simplicity in application. Further

This book consist of several chapters where we details describe about Human Resource Management in a very well-known Garment company in Bangladesh. We really found a very fruitful information through this study. However there are a lot of gaps in a managerial skills and to trainer who really do not have enough knowledge to develop their employee. W
