One of the main challenges in developing magnetic resonance imaging (MRI) systems is to create a static coil that needs to generate magnetic field density along with the characteristics of optimal homogeneity and magnitude size. To do this, two N42 Block PMs are used and the iron core is designed and optimized in accordance with the dimensions of PM pieces using ANSYS Maxwell software. Then, al...

1) Uniform Wall Thickness, Coring & Mass Reduction since injection molding is employed as the shape forming process step, part designs can avoid the limitations of traditional metalworking processes. For example, machining involves the removal of material from a solid shape to get to the desired final component design. As a result, design engineers are limited to design decisions that can be re...

This application note covers the most common EMC problems designers encounter when using microcontrollers. It will briefly discuss the various phenomena. The reference literature covers EMC design in more detail, and for designers who are going to build products that need to be EMC compliant, further study is highly recommended. A good EMC design requires more knowledge than what can be put int...

considerations for MRAM T. M. Maffitt J. K. DeBrosse J. A. Gabric E. T. Gow M. C. Lamorey J. S. Parenteau D. R. Willmott M. A. Wood W. J. Gallagher MRAM (magnetic random access memory) technology, based on the use of magnetic tunnel junctions (MTJs) as memory elements, is a potentially fast nonvolatile memory technology with very high write endurance. This paper is an overview of MRAM design co...

The Xpress Transfer Protocol, XTP, is an approach to protocol design for next generation networks. The Protocol Engine, PE, is a hardware architecture for implementing network protocols and system interfaces using VLSI techniques. The two projects are related: XTP is designed with a PE in mind. This paper presents some of the ideas and goals in XTP. Introduction XTP [1] represents a compromise ...

Memory-System Design Considerations for Dynamically-Scheduled Microprocessors Keith Istvan Farkas Doctor of Philosophy Graduate Department of Electrical and Computer Engineering University of Toronto 1997 Dynamically-scheduled processors challenge hardware and software architects to develop designs that balance hardware complexity and compiler technology against performance targets. This disser...

This paper is concerned primarily with screw conveyors with fully enclosed tubular casings. The throughput, torque and power are significantly influenced by the vortex motion of the bulk solid being conveyed. The vortex motion, together with the degree of fill, govern the volumetric efficiency and, hence, the throughput. This, in turn, influences the torque, power and conveying efficiency. A th...

Highly integrated and advanced radio designs available today enable the engineer to design RF systems with greater levels of performance than ever before. Recent advancements in the areas of blocking, sensitivity, frequency control and baseband processing are influencing RF system architecture design. The purpose of this article is to explore some of these parametric attributes and consider the...

‘‘I’d really like to do a survey’’ or ‘‘Let’s conduct some interviews’’ might sound like reasonable starting points for a research project. However, it is crucial that researchers examine their philosophical assumptions and those underpinning their research questions before selecting data collection methods. Philosophical assumptions relate to ontology, or the nature of reality, and epistemolog...
