A text-based and spoken language processing framework based on the constraint dependency grammar (CDG) developed by Maruyama is discussed. The scope of CDG is expanded to allow for the analysis of sentences containing lexically ambiguous words, to allow feature analysis in constraints, and to efficiently process multiple sentence candidates that are likely to arise in spoken language processing...

Currently popular HTTP-based video delivery services generate highly variable video traffic over small time scales. This paper confirms that with sufficient transmission bandwidth available to the video traffic, small time scale variations can be reduced to a level approaching the Poisson arrivals without experiencing degradation in the video quality. The primary result in this paper is that up...

We consider the combined control problem of connection admission, flow rate, and bandwidth allocation (capacity, service-rate) under nonstationary conditions. A fluid flow model in state variable form describes the time varying mean behaviour of Available Bit Rate (ABR) traffic, which competes with Guaranteed Traffic for network resources. Using nonlinear control we derive an integrated control...

Data collection in shallow water areas presents several challenges to the scientist. In addition to being redundant and time consuming, this task when performed manually has a high probability of disturbing the test area. Obstacles that are encountered in such environments include difficulty in covering large territories and the presence of inaccessible areas due to a variety of reasons, such a...

Some dependency treebanks use special sequences of dependencies where main arguments are mixed with separators. Classical Categorial Dependency Grammars (CDG) do not allow this construction because iterative dependency types only introduce the iterations of the same dependency. An extension of CDG is defined here that introduces a new construction for repeatable sequences of one or several depe...

An important aspect of cognitive flexibility is inhibitory control, the ability to dynamically modify or cancel planned actions in response to changes in the sensory environment or task demands. We formulate a probabilistic, rational decision-making framework for inhibitory control in the stop signal paradigm. Our model posits that subjects maintain a Bayes-optimal, continually updated represen...

In the context of Networked Control Systems (NCS), communication time delays strongly influence on the Quality of Control (QoC) of process control applications. The goal of this paper is to propose a way to calculate the closed-loop communication time delay and we compensate this time delay using the pole placement design method in order to improve the QoC for CAN-based NCSs. We consider severa...

The prospective work reported in this paper explores a new approach in order to enhance the performance of an Active Fault Tolerant Control System. This proposed technique is based on a modified recovery/trajectory control system which considered a reconfigurable reference input when performance degradation occurs on system due to faults in actuators dynamics. The added value of this work is to...

Introduction The policy of free personal care for the elderly in Scotland was implemented in July 2002. Work on the costings of the exercise had been undertaken by the Care Development Group (CDG), a group established by the Minister for Health and Community Care, and chaired by Malcolm Chisholm. Research to assist in the costings was specially commissioned and the research papers were publishe...

The cognitive cooperative system with coexisting scenario of multiple primary users and one secondary capable of relaying is considered in this study. The primary users transmit packets in orthogonal subchannels. According to the cognitive principle, the secondary activity cannot interfere with the primary performance. Therefore in this study, the secondary user makes use of the spectrum when s...
