An experimental study is conducted on flow past a circular cylinder fitted with some tripping wires on its surface. The work investigates the dependency of the critical wire locations on the wire size and Reynolds numbers, and examines the wake and vortex shedding characteristics in an effort to advance the understanding of the critical wire effects beyond the existing literature. The primary a...

Today, most research institutes dealing with landmine detection as a topic and even within many mine action communities there is a stereotype landmine image, where the only challenge is considered to be the detection of the small lowor nonmetallic anti-personnel blast mine. Indeed, this plastic cased pressure operated mine is difficult to detect. However, to the well protected deminer adhering ...

This paper describes the result of the wire handling experiment by the advanced robotic hand (ARH) on ETSVII. The ARH, a small robot system with multi-sensory hand, has been developed by MITI-ETL to execute precise tasks under extra vehicular conditions in space in an ETSVII robot experiment. The wire handling task has been proposed for the ARH experiment as one of such delicate tasks. I t requ...

Landslides are a serious geological hazard caused when masses of rock, earth, and debris flow down a steep slope during periods of intense rainfall and rapid snow melt. The western (Konkan) coast and the Himalayan region of India are subject to many such landslides every year. Landslides in these rocky regions are mainly caused by the increase in strain due to percolating rain water in rocks fi...

According to the physical process of discharge development of insulator that is struck by lightning, the lightning flashover model for quadruple-circuit transmission line with dual voltage 220kV/110kV in same tower is established basing on EMTP. The actual evaluation index of lightning protection performance is adopted with the consideration of influence of system voltage. The characteristics o...

What is a landmine? The purpose of a landmine is to disable, immobilize or kill. It is an explosive device activated either by a person or vehicle, or command detonated by electric wire or radio signal. Most landmines are laid on or just below the surface of the ground and are activated by pressure or trip-wire. Normally manufactured from very durable materials such as plastic, bakelite, concre...

Efficient VM communication in Cloud computing infrastructures is an important aspect of HPC application deployment in clusters of VMs. In this paper we present Xen2MX, a high-performance messaging protocol, binary compatible with Myrinet/MX and wire compatible with MXoE. Its design is based on MX and its port over generic Ethernet adapters, Open-MX. Xen2MX combines the zero-copy characteristics...
