A numerical simulation has been performed to investigate the control of base pressure with microjets in a suddenly expanded duct. Microjets placed at the pitch circle diameter (PCD) of 13 mm, two micro jets of 1 mm orifice diameter located at 900 for active control. The flow Mach number of the investigation was M = 2.2, the L/D ratio of the enlarge

Crack propagation until fracture is an important criterion to predict a structure‘s service life. In order to increase the latter, the cracked component needs to be repaired or replaced. In the present study, a finite element analysis has been carried out to investigate the effects of adhesive thickness, patch thickness and crack length on the pa

The blunt base either in the front or at the rear portion of the vehicles is prevalent and is found in railways where the front and rear portions the coaches are blunt, which results in zero velocity and hence the stagnation pressure, which is undesirable. The aim of this study is to investigate the effect of the splitter plate on the wake control

This paper investigates the influence of repair configuration on a rectangular plate with a circular hole and subjected to uniform tensile load. The fundamental idea is to study the stress created by either a composite or piezoelectric (PZT) patch on a hole along the width of a rectangular plate. Finite element ANSYS software was used to evaluate t

Learning management systems have been largely used in universities for teaching, student learning, curriculum, and staff development. However, just providing higher education institutions with a learning management system does not guarantee a success. Quality assurance of these systems has become a central concern for practitioners, researchers, an

Online theft of trade secrets and commercial cyber espionage are growing threats to businesses and national economy in this digital economy. This global phenomenon of targeting trade secrets of corporation has caused the loss of billions of dollars in the UK, US, Japan and some others. These crimes are committed by rivals and in most cases with the

Although web-based learning systems are emerging as a useful tool for facilitating teaching and learning activities, instructors’ use of learning management systems in higher educational institutions is still limited. In this context, this empirical research investigates factors that can potentially contribute to learning management system adopti

This paper contributes to the literature by providing empirical evidence on the relationship between financial development, economic growth, and poverty in Indonesia in the period of 1980–2014. This issue is of importance for developing economies such as Indonesia given the high rate of poverty in the country despite the rapid growth of the finan

The advancement of Information and Communication Technology (ICT) offers positive and negative impacts in our daily life today. Criminals too leverage on sophisticated ICT in their modus operandi. Hence, digital evidences are abundant to be acquired and analysed as part of investigation, today. Two homegrown tools i.e. PenDua and Kloner are used fo

This study focus on reinforcing of durian skin fiber (DSF) and polylactic acid (PLA) for food packaging. Epoxidized palm oil (EPO) was used as a plasticizer to enhance the properties of the biocomposite. The biocomposite was fabricated by extrusion and injection molding processes. The tensile properties of PLA/DSF with EPO improved by 9.3% and 70.0
