Distributed Control Systems (DCS) provide a modular, reliable, and cost-effective method of implementing control systems, with superior data management capabilities. They are being used, not just for new plants and equipment, but also for control system upgrades at existing installations. Their increasing prominence in control rooms require that they be accurately represented in the simulation ...

The ever increase of nonlinear loads in electric distribution networks causes many problems due to the high level of harmonic currents. This paper proposes a new technique for controlling a single phase shunt active power filter based on a selective compensation using the newly developed technique of harmonic control arrays. Simulation results confirm the appropriate selective harmonic compensa...

The 3rd Generation Partnership Project (3GPP)’s Long Term Evolution (LTE) standards define the next major step in the evolution of cellular systems towards higher data rates, low latency, and greater spectral efficiency. This occurs in the context of a System Architecture Evolution (SAE) that specifies a packetswitched IP architecture for both voice and data transmission. We present a simulatio...

•Thermal isomerization pathways of donor-acceptor Stenhouse adducts are tuned by polarity•Non-selective stimuli produce selective responses in the DASA mixture Natural systems such as cells or organisms consist thousands stimulus-responsive and adaptive molecules assemblies enzymes proteins. To achieve a multitude selectivity despite limited set available stimuli, nature relies on highly contro...

A quasi-independence result holds for the go-back-n automatic repeat request (ARQ) protocol and the sliding window ow control protocol if packet errors are independent. The result is independent of the magnitude of the packet error probability or the cost of an error. A parallel result for the selective repeat ARQ protocol, however, does not appear to hold. Parts of this paper were presented as...

We propose k-SACK, a TCP variant that has considerably improved throughput characteristics over lossy links. A k-SACK source does not consider every packet loss as an indication of congestion. It uses the Selective Acknowledgement option to estimate a parameter lookaheadloss, which is used in congestion detection. Our results demonstrate that kSACK maintains a steady performance in a non-lossy ...

Sterilization of packages prior to product filling is a key step in aseptic filling machines. Chemical sterilization is one of the main conventional techniques in many packaging industries. To monitor the effect of sterilization on test microorganisms (Bacillus atrophaeus spores), an impedimetric sensor approach was developed based on a planar interdigitated electrode (IDE) design. In this work...
