BACKGROUND Magnetic resonance imaging (MRI) is a versatile technique for examination of the cardiovascular system but only recently has assessment of myocardial ischaemia in coronary artery disease (CAD) become possible, for example by demonstrating abnormalities of regional ventricular contraction during stress. Global ventricular function during stress was assessed by MRI of aortic flow, whic...

Computer clusters made of mass-produced, off-the-shelf components are able to deliver the same real-life performance on a variety of tasks as other types of supercomputers, but at a lower cost. Current ad hoc design practices are characterised by only partial exploration of design space and inability to accurately predict capital and operating expenses. We provide the framework for a more compr...

In the past few decades, Computer Aided Design (CAD) systems have evolved from 2D tools that assist in construction design to the basis of software systems for a variety of applications, such as (re)design, manufacturing, quality control, and facility management. The basic functions of a modern CAD system are storage and retrieval of 3D data, their construction, manipulation, and visualisation....

Introduction In the system engineering of complex systems that include digital automation, the most vexing and potentially costly problems arise in the early stages of development. Few adequate tools exist to assist in developing system requirements and architectures and translating the system requirements to software requirements. Serious unsolved problems also exist at the other end of the li...

Computer-aided design (CAD) uses computer based facility to assist engineers and design professionals in their day to day activities. As a fundamental engineering skill, CAD software is normally taught to the first year undergraduate student. Unlike the other undergraduate engineering courses, the CAD teaching mainly relies on one to one teaching and learning environment. This requires extensiv...

The DIJA project is a web-based CAD system accessible to any user (from neophyte to expert) and from a simple desktop computer. Its modeling approach is based on a top-down methodology and takes into account trade information. In this paper, we propose a network architecture based on a replication process and a multi-level language to manage the consistency between the client model and the serv...

In order to manufacture smaller and more efficient electric motors an accurate prediction of the motor thermal performances at the design stage is a necessity. In addition, the thermal performance often needs to be analyzed when a motor is used in a different way to which it was originally designed for. An important example is the use of variable speed drives with induction motors designed for ...

objective(s): coronary artery disease (cad) is the leading cause of death in both male and female worldwide. the main cause of cad is the atherosclerosis of coronary arteries, which is, mostly caused by genetic alteration. 50% of such cases occur in mitotic cells where single-strand breaks occur spontaneously or due to ionizing radiation. x-ray repair cross-complementing protein 1 (xrcc1) as a ...

GeoDesign enhances traditional Environmental planning and Design activities with the power of modern computing, communications, and collaboration technologies, providing on-demand simulations and impact analyses to provide more effective and more responsible integration of scientific knowledge and societal values into the design of alternative futures. For practitioners, as well as students and...
