A Computer-Aided-Test (CAT) platform has been integrated in the Cadence Design Framework Environment for the evaluation of analogue/mixed-signal/RF Built-In-Self-Test (BIST) techniques. It comprises tools for statistical modelling of circuit performances, fault simulation, test generation and test optimization. The fault modelling and fault injection tools are simulator-independent, thus they a...

Shortest path routing schemes like Open Shortest Path First (OSPF) have shortcomings when networks are highly loaded. Traffic engineering of IP networks is required to avoid this problem. Current efforts suggest the optimisation of OSPF weights to balance the network load more evenly. Also more advanced technologies like Multiprotocol Label Switching (MPLS) are proposed. One major problem of dy...

Redundancy removal is an important step in combinational logic optimisation. After a redundant wire is removed, other originally redundant wires may become irredundant, and some originally irredundant wires may become redundant. When multiple redundancies exist in a circuit, this creates a problem where we need to decide which redundancy to remove first. The authors present both a theoretical a...

H-optimisation (Givens, 1997; 1999a; Givens et al. 1999) and U-optimisation (Witting , 1999)|two methods for optimising Strike Limit Algorithms|are compared on theoretical principles and simple examples. Despite some appealing and innovative features, U-optimisation is not a reliable method in its current formulation. Two new H-optimisation strategies are described which incorporate the most ap...

This paper presents a study on parameterisation methods for airfoil shape optimisation within a CAD-based design optimisation framework. The objective of the paper is to study the effect of different methods on airfoil shape optimisation when using computational fluid dynamics (CFD). Parameterisation of geometry is one of the essential requirements in shape optimisation, and it presents further...

extended interaction oscillators (eio) are vacuum electronic sources of microwave, millimeter-wave and terahertz radiations. in this paper, eio is investigated by using a circuit model. the value of the coupling element in the model is evaluated from the near band-edge dispersion characteristics of the rf structure. the end external loading of the interaction structure is equivalently modeled b...

This paper presents the design, construction and testing of a new capacitive tactile sensor for measurement of normal tactile force. The operation of proposed sensor has been investigated in ASTABLE and MONOSTABLE circuits. According to the results of these circuits the deviation of ASTABLE circuit results is less than MONOSTABLE circuit results. In addition, the results obtained from ASTABLE c...

The present research reviews two basic approaches for the separation circuit configuration analysis. The first approach is to optimize the circuit configuration. In this method, after a circuit modeling, a variety of search algorithms and mathematical optimization methods are used. Previous works show that this approach has more application in the flotation process. The second approach called t...

In this paper a new synthesis for circuit design of Euclidean distance calculation is presented. The circuit is implemented based on a simple two-quadrant squarer/divider block. The circuit that employs floating gate MOS (FG-MOS) transistors operating in weak inversion region, features low circuit complexity, low power (<20uW), low supply voltage (0.5V), two quadrant input current, wide dyn...

The aim of this paper is to present an application and a framework using evolutionary algorithms like Genetic algorithms (GA) for solving real-life design optimisation problems. The application is centred around an engineering optimisation toolbox applied to the design optimisation of gas turbine combustor. This toolbox can handle high-dimensional problems and ease the computational cost of sim...
