Performance tests were carried out for a microchannel printed circuit heat exchanger (PCHE), which was fabricated with micro photo-etching and diffusion bonding technologies. The microchannel PCHE was tested for Reynolds numbers in the range of 100‒850 varying the hot-side inlet temperature between 40 °C–50 °C while keeping the cold-side temperature fixed at 20 °C. It was found that the average...

In this paper we describe a multi-module, multi-port memory design procedure that satisfies area and/or energy constraints for embedded applications. Our procedure consists of application of loop transformations and reordering of array accesses to reduce the memory bandwidth followed by memory allocation and assignment procedures based on ILP models and heuristic-based algorithms. The specific ...

From a security standpoint, it is preferable to implement least privilege network security policies in which only the bare minimum of TCP/UDP ports on internal hosts are accessible from outside the perimeter. Unfortunately, organizations with such policies can no longer communicate using common multiport protocols that require randomly chosen ports for auxiliary connections. This paper introduc...

We introduce and report recent developments on a novel five port optoelectronic voltage controlled oscillator consisting of a resonant tunneling diode (RTD) optical-waveguide integrated with a laser diode. The RTD-based optoelectronic oscillator (OEO) has both optical and electrical input and output ports, with the fifth port allowing voltage control. The RTD-OEO locks to reference radio-freque...

This paper presents a method for managing and modeling a product family as a configurable product. The method enables efficient management of a large number of product variants. The modeling is based on a recently proposed conceptualization of configuration domain, which is a synthesis and extension of the main approaches to configuration. The concepts of the conceptualization are components, a...

This paper investigates the thermodynamic framework of a three-bed advanced adsorption chiller, where the mass recovery scheme has been utilized such that the performances of this chiller could be improved and a CFC-free-based sorption chiller driven by the low-grade waste heat or any renewable energy source can be developed for the next generation of refrigeration. Silica gel-water is chosen a...

Constructing flow-through reactors for chemiluminescence detection by machining channels into polymer disks has enabled the exploration of new configurations and materials that can improve signal intensity beyond that attainable with the traditional coiled-tubing design. Several approaches to merge reactant solutions were examined: an intersection, chamber or deeper well in the centre of a serp...

Autonet is a self-configuring local area network composed of switches interconnected by 100 Mb/s, full-duplex, point-to-point links. The switches contain 12 ports that a re internally connected by a full crossbar. Switches use cut-through to achieve a packet forwarding latency as low as 2 ms/switch. Any switch port can be cabled to any other switch port o r to a host network controller. A proce...

This paper reports the development of microfluidic oxygenator (MFO) units designed for a lung assist device (LAD) for newborn infants. This device will be connected to the umbilical vessels like the natural placenta and provide gas exchange. The extracorporeal blood flow is only driven by the pressure difference between the umbilical artery and vein without the use of external pumps. The LAD is...

Autonet is a self-configuring local area network composed of switches interconnected by 100 Mbit/second, full-duplex, point-to-point links. The switches contain 12 ports that are internally connected by a full crossbar. Switches use cut-through to achieve a packet forwarding latency as low as 2 microseconds per switch. Any switch port can be cabled to any other switch port or to a host network ...
