A numerical simulation was carried out to compare various turbulence models simulating axisymmetric nozzle flow past suddenly ex-panded ducts. The simulations were done for L/D = 10. The convergent-divergent nozzle has been modeled and simulated using the turbu-lence models: The Standard k-ε model, The Standard k-ω model and The SST k-ω model. N

Oral health is a component of overall health that has an impact on an individual’s general well-being. It is believed that individuals enrolled in undergraduate health sciences are expected to have a positive attitude and behaviour toward their oral health. This study is conducted to investigate and compare the oral health attitudes and behaviour

Increasing proliferation of IoT has led to an evolution of various devices for realizing the smart features of ubiquitous applications. However, the inclusion of such a massive pool of devices with different computational capabilities, network protocols, hardware configurations, etc. also causes a higher number of security threats. Security profess

Applications meant for exchanging cash, or individual data are becoming progressively common in mobile communications and on the Internet. The expansion of electronic banking services by utilizing various electronic channels provide added value to the users. As such, client authentication is required in these applications for affirming the legitima

The Internet of Things (IoT) smart city initiative has transformed technology spectrum into its new era of development. The increasing amount of data generated by millions of IoT devices and the rapid flow of data across distributed IoT devices are transmitting to remotely located cloud infrastructure over the Internet. Unfortunately, these large a

The integration of renewable energy sources (RES) poses challenges due to their intermittent nature and the requirement for grid stability and reliability. This study explores the application of Model Predictive Control (MPC) as an advanced control strategy for effective RES integration. MPC utilizes mathematical models and prediction algorithms to

This paper presents numerical study was undertaken to identify the use of the micro-jets to regulate the pressure in the region from two-dimensional convergent-divergent (CD) Nozzle. At the exit of the divergent nozzle in the base region 1 mm of two micro-jets orifice diameter has been arranged at ninety degrees at pcd 13 mm to control base pressur

Electrical discharge machining (EDM) is a nontraditional process of removing material from an electrically conductive work piece. It produces sparks to produce any desired shape cavity or geometry. The demand for good surface finish of a workpiece in EDM has developed a new method to improve surface condition where powder material is added to diele

Stay connected is a well-known advantage of telecommunications. Telecom diligence have introduced an easy and enormous way to people to keep in touch. From the last decades, a remarkable growth is noted in telecommunication industry. The number of telecom users has enormously increased. With increasing demands, it is becoming challenges for CSPs (C

Nasopharyngeal carcinoma (NPC) is among the most frequently reported cancer in Malaysia. The most recent National Cancer Registry (NCR), stated that NPC was the fourth most common cancer among Malaysian and third most common cancer among Malaysian men. While there have been several studies on NPC previously carried out in a few states in Malaysia,
