Parametric faults are a significant cause of incorrect operation in analog circuits. Many design for test techniques for analog circuits are ineffective at detecting multiple parametric faults because either their accuracy is poor, or the circuit is not tested in the configuration in which it is used. We present a design for test (DFT) scheme that offers the accuracy needed to test high-quality...

This paper presents a methodology for observing human skill by using a virtual task space constructed by the haptic virtual reality technology. First a haptic simulator developed for a 2-dimensional pegin-hole assembly operation in the virtual environment is presented. To examine the validity of the simulator, a comparison study between the peg-in-hole task using the simulator and that in the r...

A key challenge in the area of bioinformatics in the coming decades is the ability to manage the wealth of information that is being generated from the variety of high throughput methodologies currently being undertaken in laboratories across the world. While these approaches have made available large volumes of data to the research community, less attention has been given to the problem of how...

In the present paper, a computer-aided approach to fault observability investigation of linear analog circuits is developed. The method is based on sensitivity investigation of the test characteristics in the frequency domain. The test frequencies are selected maximizing the sensitivity of the magnitude of the test characteristics. Applying postprocessing of the simulation results using macrode...

In almost all of the currently working circuits, especially in analog circuits implementing signal processing applications, basic arithmetic operations such as multiplication, addition, subtraction and division are performed on values which are represented by voltages or currents. However, in this paper, we propose a new and simple method for performing analog arithmetic operations which in thi...

In the present paper we report experimental observations of discrete spatiotemporal structures in rings of unidirectionally coupled analog Lorenz systems. This is an extension of the results previously reported in [Sánchez & Mat́ıas, 1998], studying now other parameter regimes. These studies are based on the use of an analog circuit corresponding to Lorenz equations. The more interesting new res...
