There are very few reports in the past on applications of Evolutionary Strategy (ES) towards the synthesis of analogue circuits. Moreover, even fewer reports are on the synthesis of computational circuits. Last fact is mainly due to the difficulty in designing of the complex nonlinear functions that these circuits perform. In this paper, the evolving power of the ES is challenged to design four...

A dynamic model for the simulation of a new single-effect water/lithium bromide absorption chiller is developed. The chiller is driven by two distinct heat sources, includes a custom integrated falling film evaporator-absorber, uses mixed recirculation and is exclusively cooled by the ambient air. Heat and mass transfer in the evaporator-absorber and in the desorber are described according to a...

The recently developed multiresolution time-domain technique (MRTD) is applied to the modeling of open microwave circuit problems. Open boundaries are simulated by the use of a novel formulation of the perfect matching layer (PML) absorber. PML is modeled both in split and nonsplit forms and can be brought right on the surface of the planar components. The applicability of the MRTD technique to...

The properties of capacitative Ca(2+) influx were studied using the whole-cell patch-clamp technique in crypts isolated from rat distal colon. Store-operated cation influx was evoked by increasing the intracellular buffering capacity for Ca(2+) in the pipette solution; contamination by Cl(-) currents was reduced by the use of NMDG gluconate as the main electrolyte in the pipette solution. The p...

We investigate experimentally parity-time (PT ) symmetric scattering using LRC circuits in an inductively coupled PT -symmetric pair connected to transmission line leads. In the single-lead case, the PT -symmetric circuit acts as a simple dual device—an amplifier or an absorber depending on the orientation of the lead. When a second lead is attached, the system exhibits unidirectional transpare...

Highly sensitive and fast photodetectors can enable low power, high bandwidth on-chip optical interconnects for silicon integrated electronics. III-V compound semiconductor direct-bandgap materials with high absorption coefficients are particularly promising for photodetection in energy-efficient optical links because of the potential to scale down the absorber size, and the resulting capacitan...

Recent advances in technology are leading to increases in the complexity and applications of analogue and mixedsignal integrated circuits. This trend has been accomponied by an increase in the complexity of associated test specifications. Furthermore, the use of functional & specification based test programs for the analogue circuitry is being questioned due to high implementation costs, the di...

This paper discusses the use of temperature as a test observable for analogue circuits, presenting a generic configuration for analogue circuit thermal testing. As a case study, static temperature analysis is performed over a two-stage operational amplifier in view of extracting temperature waveforms at different locations on the circuit under test, both under fault-free conditions as well as i...

Switched reluctance motors (SRM) are attracting much attention because of their special advantages. Generated heat, due to losses, can reduce the life time of SRMs. Therefore, taking into account thermal modeling helps to improve their performance and increase their life time. In this paper, a lumped thermal model of SRM based on the analogue circuit of conductive and convective thermal resista...
