Experimental studies were conducted in sudden expansion axi-symmetric passage for controlling base pressure and their outputs were showcased in current paper. Micro jet active control techniques are used for controlling base pressure. These controls constitute four spaces around base and symmetric to nozzle axis. Mach numbers of the abruptly expand

This study examined the quality of life against the backdrop of the existing environment in the public low-income housing estates. Based on the desktop literature the study used both subjective and objective measurements to investigate the liveability of the selected housing estates. Home environment, neighbourhood amenities, economic vitality, soc

Striped catfish, Pangasianodon hypophthalmus is a native species to most Asian countries, including Malaysia which faced series of bacterial disease such as edwardsiellosis caused by E.ictaluri. Edwardsiella ictaluri is a Gram-negative intracellular bacterial pathogen which had caused mortalities in farmed or wild fish in lots of countries and acco

This paper proposes a consensus tracking control for a class of second-order multi-agent nonlinear systems and generalizes the concept of integral sliding mode for networked systems. This design relies upon an integral manifold which is defined as a function of the consensus error variables. The designed integral manifold helps in the establishment

The increasing demand for wearable technology has underscored the need for sustainable energy sources, leading to the development of wearable nanogenerators on flexible fabric. Piezoelectric nanogenerators based on ZnO nanorods provide a promising solution to power wearable devices through body movements. The hydrothermal method was chosen for the

Compressible flow in a suddenly expanded square duct was investigated experimentally to assess the effectiveness of the passive control in the form of the cavities. The flow parameters studied were the Mach number, nozzle pressure ratio, L/W ratio, and area ratio. The test were conducted for multiple cavities and without multiple cavities. From exp

Flow control in high-speed is challenging due to the high-pressure shock and low-pressure recirculation bubble attached around the vehicle. Wave drag, and Base drag are important accouterments of flow around high-speed objects. This paper deals with base drag, only and presents an experimental study of aerospikes behind the base of bluff bodies to

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.
