− This paper describes an analogue processing element (APE) suitable for high-density image sensor/processor array integrated circuits. The design tradeoffs between area, power consumption, speed and accuracy are discussed and the architecture of the APE is presented. The design follows a switched-current “analogue microprocessor” approach while the implementation of arithmetic operations is si...

We analyse the effects of analogue noise on the synaptic arithmetic during multilayer perceptron training by expanding the cost function to include noise-mediated penalty terms. Predictions are made in the light of these calculations which suggest that fault tolerance, generalisation ability and learning trajectory should be improved by such noise-injection. Extensive simulation experiments on ...

The possibility of using window comparators for onchip (and potentially on-line) response evaluation of analogue circuits is investigated. No additional analogue test inputs are required and the additional circuitry can be realised either by means of standard digital gates taken from an available library or by full custom designed gates to obtain an observation window tailored to the applicatio...

This paper deals with the feedback control of a DC motor speed with using the fractional-order controller. The permanentmagnet DC motor is often used in mechatronic and other fields of control theory and therefore its control is very important. The mathematical description of the fractional order controller and its implementation in the analogue and the discrete domains is presented. An example...

This paper proposes a built-in self-test (BIST) scheme for noise-tolerant testing of a digital-to-analogue converter (DAC). The proposed BIST calculates the differences in output voltages between a DAC and test modules. These differences are used as the inputs of an integrator that determines integral nonlinearity (INL). The proposed method has an advantage of random noise cancelation and achie...

The paper describes work at the Polytechnic of Huddersfield on SERC/DTI research project IED 2/1/2121 conducted in collaboration with GEC-Plessey Semiconductors, Wolfson Microelectronics, and UMIST. The aim of the work is to develop generic testing strategies for mixed-signal (mixed analogue and digital) integrated circuits. The paper proposes a test structure for mixed-signal ICs, and details ...

background & aim:  self-confidence, as one of the key elements of clinical competence, plays an important role in one’s actions and behaviours. selection of proper instructional methods influences students’ self-confidence. therefore, this study aimed to compare the effects of web-based training and educational simulation on midwifery students’ self-confidence in postpartum hemorrhage managemen...
