Selection of airfoil is one of the most critical factors in achieving better aerodynamic performance and in determining the optimum dimensions of a fixed-pitch straight-bladed Darrieus type vertical axis wind turbine (SB-VAWT), along with solidity, radial arm parasitic drag, aspect ratio etc. Airfoil related design changes also have the potential f

Objectives: This study was aimed at regenerating autologous elastic cartilage for future use in pediatric ear reconstruction surgery. Specific attentions were to characterize pediatric auricular chondrocyte growth in a combination culture medium and to assess the possibility of elastic cartilage regeneration using human fibrin. Study design: Labora

This paper presents an efficient method of optimisation of surface roughness in end milling of Inconel 718 using TiAlN coated inserts under dry conditions by coupling response surface methodology (RSM) with genetic algorithm (GA). RSM has been utilized to develop an efficient mathematical model for surface roughness in terms of cutting parameters.

The growth of the Internet as a vehicle for secure communication has resulted in Data Encryption Standard DES) no longer capable of providing high-level security for data protection. Triple Data Encryption Standard (3DES) is a symmetric block cipher with 192 bits key proposed to further enhance DES. Many applications crave for the speed of a hardwa

An approach to develop the FPGA of a flexible key RSA encryption engine that can be used as a standard device in the secured communication system is presented. The VHDL modeling of this RSA encryption engine has the unique characteristics of supporting multiple key sizes, thus can easily be fit into the systems that require different levels of secu

Several control policies of quarter-car 2 degree-of-freedom semiactive system, namely skyhook, groundhook and hybrid controls are presented. Their ride comfort, suspension displacement and road-holding performances are analyzed and compared with passive system. The analysis covers both transient and steady state responses in time domain and transfe

A matrimonial home occupies a very important place in one married life. Not only it becoming more common for the family to buy their own house, but in many cases the matrimonial home is the most substantial assets of the spouse. Thus, it is undeniable fact that typically, matrimonial home is a major asset, if not the only assets of the family. In p

This paper tends to the subject of hospitality (ḍiyāfah) and elucidates its social standing and coupled terms by outlining the personification of hospitality in community development through the eyes of the Prophetic Tradition (Sunnah). The research clarifies the essential components of hospitality, with a specific spotlight on the association o

تواجه الكثير من المؤسسات الوقفية صعوبات تمويل مشاريع الأوقاف وتطويرها وتحويلها لأوقاف منتجة، ذات ايراد عالى واكثر فاعلية في مساهمتها التنميوية، والأوقاف في سنغافورة من النماذج التي يهتدى به

Recent industrial revolutions cause bauxite mining activities across the globe to become notably more active. However, ceasing bauxite mining activities left bauxite mining sites barren without any vegetation, causing environmental and health problems, such as dust and red muds. Existing remediation techniques such as physical separation, incinerat
