This study investigates the fluid flow through the runner of an exceptionally low specific speed Francis’ turbine using computational fluid dynamics (CFD) to predict some performance characteristic of the runner, and to ...

The need for fast maneuvering and accurate positioning of flexible structures poses a control challenge. The flexibility inherent in these lightly damped systems creates large residual vibrations in response to fast ...

There is a growing use of polymers in different applications worldwide. This phenomenon resulted in an enormous increase in the amount of plastic waste. These wastes have significant impacts on the environment including ...

Nanostructured materials have attracted many researchers due to their outstanding mechanical and physical properties. One example is Carbon Nanotube (CNT) reinforced composites. Although most researchers have focused on ...

Friction Stir Welding (FSW) is a new solid state welding technique which is characterized by its ability to join the difficult-to-weld alloys, notably aluminum alloys. Microstructural studies revealed that FSW produces ...

Revenue Management, also known as yield management, is a technique used by airline industries to maximize revenue by allocating the available seats to the right customers at the right price. Overbooking is an airline revenue ...

Layered silicate clays have been used for decades as filler materials to enhance mechanical and thermal properties of polymers. Recently, efforts have focused on separating the layers of the clay with the purpose of forming ...

Natural composites have become a necessity with which we should not dispense since they will become the solution and alternative for many traditional polymers that are made of petroleum resources. By adopting natural, ...

In the current research, a new assessment procedure is proposed to determine the shakedown limit load of locally thinned wall pressurized components via modifying the current API 579 level-three assessment. The new assessment ...

Aluminum's many exceptional properties promote it to be as a strong candidate for several applications in the aerospace, automotive, building and packaging industries to name a few. As a result, strengthening Aluminum has ...
