Abstract The aim of this research is to develop methodology and provide insight into the viability using Open Pore Cellular Foam (OPCF) material in Polymer Electrolyte Membrane (PEM) Electrolysers. Analysis have therefore been carried out on three different types electrolyser geometries. A PEM considered with serpentine, mesh OPCF flow channels, whilst all other physical operational parameters ...

this study seeks to examine how a company can select the best intermediary for its marketing channels with minimum of criteria and time. a theoretical framework is proposed based on the most important tasks of intermediary and the criteria to measure them. there are four basic tasks and thirty criteria in three independent levels. subsequently, an exploratory case study in iranian food industry...

Serpentine robots are slender, multi-segmented vehicles designed to provide greater mobility than conventional mobile robots. Serpentine robots are ideally suited for urban search and rescue, military intelligence gathering, and for inspection tasks in hazardous or inaccessible environments. One such serpentine robot, developed at the University of Michigan, is the “OmniTread OT-4.” The OT-4 co...

Serpentine robots are slender, multisegmented vehicles designed to provide greater mobility than conventional wheeled or tracked robots. Serpentine robots are thus ideally suited for urban search and rescue as well as for surveillance and inspection tasks in hazardous and hard-to-reach environments. One such serpentine robot, currently under development at the University of Michigan, is the “Om...

Many industrial applications require inspections and surveillance in hard-to-reach and sometimes even hazardous areas. A relatively new kind of robotic mechanism, called a “serpentine robot,” may be able to provide a solution to some of these applications. Serpentine robots are slender, multisegmented vehicles designed to provide greater mobility than conventional wheeled or tracked robots. Thi...

Giant serpentine aneurysms are fusiform partially thrombosed aneurysms with a separate outflow tract to normal distal cerebral vessels. Three patients with giant serpentine aneurysms of the anterior and middle cerebral arteries were treated with endovascular occlusion of the aneurysmal lumen with coils or glue after balloon test occlusion of the involved vessel. In all 3 patients, leptomeningea...

We study the transport of Brownian particles under a constant driving force and moving in channels that present a varying centerline but have constant aperture width (serpentine channels). We investigate two types of channels, solid channels, in which the particles are geometrically confined between solid walls and soft channels, in which the particles are confined by the potential energy lands...

Among the most visually striking river restoration projects are those that involve the creation of a new channel, often in a new alignment and generally with a form and dimensions that are different from those of the preproject channel. These channel reconstruction projects often have the objective of creating a stable, single-thread, meandering channel, even on rivers that were not historicall...

The operation of polymer electrolyte membrane fuel cells (PEMFCs) with dry feeds has been examined with different fuel cell flow channel esigns as functions of pressure, temperature and flow rate. Auto-humidified (or self-humidifying) PEMFC operation is improved at higher pressures nd low gas velocities where axial dispersion enhances “back-mixing” of the product water with the dry feed. We dem...
