A plasma wakefield accelerator (PWFA) experiment is conducted at the Stanford Linear Accelerator Center. The experiment aims at studying the issues relevant to a meter-long plasma accelerator module in the context of an actual high-energy collider. The transverse dynamics issues include transport and focusing of the beam. The longitudinal dynamics issues are the loss and gain of energy by the b...

Background. A field study conducted by researchers found the balls used by visual impairment students at school basically used the sound by a small bell inside the ball. However, the sound emitted from the ball is very limited, the ball will sound when it is moved. This makes it difficult for students with visual impairments to find a missing ball that not emitted makes a sound. Objectives. A ...

Desired physical form of cities has been noticeable since the beginning of urbanization, from old patterns of early civilizations to the latest urbanism’s theories, which offered to build better cities. The opinions in recent decades have expressed that compact physical form of cities is a better form than sprawl form to achieve urban sustainability. The form of the city is the embodiment of it...
