In order to understand complex genetic regulatory networks researchers require automated formal modelling techniques that provide appropriate analysis tools. In this paper we propose a new qualitative model for genetic regulatory networks based on Petri nets and detail a process for automatically constructing these models using logic minimization. We take as our starting point the Boolean netwo...

Naphthol isomers were simultaneously and spectrophotometrically determined in wastewater, using a model based on net analyte signal (NAS). The calibration method used is a variation of the original hybrid linear analysis method as proposed by Goicoechea and Olivieri (HLA/GO). Owing to spectral interferences, the simultaneous determination of mixtures of naphthol isomers, using a spectrophotomet...

Continuous increases in electrical energy demand and the deregulation of power systems have forced utility companies to provide high-quality reliable services maintain a sustainable operation reduce electricity price. One way continue providing required while simultaneously reducing operational costs is through minimizing losses voltage deviation distribution network. For this purpose, Network ...

In this paper we address the problem of minimization of power consumption in combinational circuits by minimizing the number of switching transitions at the output nodes of each gate. A powerful combinational logic optimization method using k-map is presented here that is based on disjoint implicants (implicates) of a function. More than 10% reduction in switching activity has been obtained wit...

To understand the function of genetic regulatory networks in the development of cellular systems, we must not only realise the individual network entities, but also the manner by which they interact. Multi-valued networks are a promising qualitative approach for modelling such genetic regulatory networks, however, at present they have limited formal analysis techniques and tools. We present a f...

| Typical placement objectives involve reducing net-cut cost or minimizing wirelength. Congestion minimization is the least understood, however, it models routability most accurately. In this paper, we study the congestion minimization problem during placement. First, we show that a global placement with minimum wirelength has minimum total congestion. We show that minimizing wirelength may (an...

Optimal placement of switching devices is a very important for distribution networks‟ planning, operation and cost minimization. Further identifying optimal placement of switches is typical if the distribution system consists of Distributed Generators (DGs). Generally DGs are used to reduce the losses, to improve the voltage profile and to increase the reliability of the system. Further in orde...

Optical Burst Switching (OBS) is a promising switching paradigm to efficiently support Internet Protocol (IP) packets over optical networks, under current and foreseeable limitations of optical technology. The prospects of OBS networks would greatly benefit, in terms of cost and ease of implementation, from limiting the wavelength conversion capabilities at the network nodes. This paper present...
