Taken together, the emotion of disgust consisted of a rigid, reliable type of motivation and behavior, paired with an open-ended database of elicitors and a flexible acquisition system, enhanced with a sentimental signaling system available for the transmission of cultural information. As new adaptive problems arose, these features, and the mix of rigidity and flexibility they offered, made the...

A “control table” is a functional specification of the signaling system of a railway section. It specifies the routes on which trains are allowed to pass. Control table for interlocking system in Indian Railways is done by a vendor. This control table is verified for correctness by another vendor. The process followed to generate this control table remains a black box, i.e., unknown. Through th...

We analyze a priority queueing system with congestion control based on thresholds. A priority queue with a triple of thresholds consisting of an abatement threshold, an onset threshold and a discard threshold was investigated by San-qi Li. We extend Li's model to a priority queue with N triples of thresholds and obtain the stationary probabilities of queue length by using the Embedded Markov ch...

Roundabouts are widely used in Gulf area for organizing traffic at road intersections. Big traffic jams, especially at the roundabout intersections, are happening at peak hours. Since there is no traffic signal to organize the traffic at these areas, a traffic policeman has to stand there for long hours in the very hot weather (in summer in Gulf area) to organize the traffic. Off-line traffic s...

Bidirectional signalling is regarded as a notable hallmark of the Eph-ephrin signalling system: Eph-dependent forward signalling in Eph-expressing cells and ephrin-dependent reverse signalling in Ephrin-expressing cells. The notion of ephrin-dependent reverse signalling derives from genetic experiments utilizing mice carrying mutations in the intracellular region of ephrinBs. Here we show that ...

In this paper, we propose and evaluate a novel transport layer mobility management scheme: Seamless IP diversity based Generalized Mobility Architecture (SIGMA). SIGMA provides seamless handover for mobile hosts and is based on SCTP, which is a new reliable transport protocol introduced by IETF to transport SS7 signaling messages over IP network. We also show that our handover scheme can greatl...

The detection of weak signals is addressed in additive noise described by the first order moving average of a Gaussian process. We derive decision regions of the maximum likelihood (ML) and suboptimum ML (SML) detectors, and obtain specific examples of the ML and SML decision regions. The ML and SML detectors are employed in the antipodal signaling system, and compared in terms of the bit-error...

A fundamental characteristic of human speech is that it uses a limited set of basic building blocks (phonemes, syllables), that are put to use in many different combinations to mark differences in meaning. This paper investigates the evolution of such “combinatorial phonology” with a simulated population of agents. We first argue that it is a challenge to explain the transition from holistic to...

Scatternet management remains to be one of the most crucial research issues for Bluetooth networks, despite that Bluetooth devices have proliferated in the commercial market. In this paper, we describe our proposed integrated scheme for effective scatternet management. Our proposed scheme contains four main mechanisms to address the different facets of the problem, namely CompensationBased Time...

OVERVIEW: The primary role of a signaling system is to ensure the safe and stable running of trains. There is also a great need, however, for improving the efficiency of railway operations and reducing the maintenance cost through the modernization of signaling systems. One approach to meeting these needs is a highly safe and highly functional signaling system using general-purpose computers. H...
