New efficient numerical methods for hyperbolic and parabolic partial differential equations with delay terms are investigated. These equations model a development of cancer cells in human bodies. Our goal is to study numerical methods which can be applied in a parallel computing environment. We apply our new numerical method to the delay partial differential equations and analyse the error of the method. Numerical experiments confirm our theoretical results.

A quantum computer based on the manipulation and detection of coherent states of electrons localized above a helium film is described. Each quantum logic element (qubit) is made of a combination of the ground and first excited states of an electron trapped in the image potential well at the surface. Potentials applied to micro-electrodes located beneath each electron confine the lateral motion of the electron and are used to operate gates. Mechanisms for one- and two-qubit logic operations and a readout of the final state are discussed. The principle decay channel for the excited state is via the emission of one phonon into the bulk liquid. Dechoherence times are calculated to be of order of 100 mus and allow greater than 10(4) serial operations.

We present ECSGlasses: wearable eye contact sensing glasses that detect human eye contact. ECSGlasses report eye contact to digital devices, appliances and EyePliances in the user's attention space. Devices use this attentional cue to engage in a more sociable process of turn taking with users. This has the potential to reduce inappropriate intrusions, and limit their disruptiveness. We describe new prototype systems, including the Attentive Messaging Service (AMS), the Attentive Hit Counter, the first person attentive camcorder eyeBlog, and an updated Attentive Cell Phone. We also discuss the potential of these devices to open new windows of interaction using attention as a communication modality. Further, we present a novel signal-encoding scheme to uniquely identify EyePliances and users wearing ECSGlasses in multiparty scenarios.

The use of a hybrid scheme and intelligent mobile agents (IMA) to monitor security of networks is discussed. The scheme consists of a Policy Manager agent, responsible for managing security policies and responding to network attacks. The task is assisted by a variety of mobile agents running on a mobile agent platform which help applying configurations locally. The Policy Manager and the mobile agents are enhanced with reasoning capabilities in the form of a rule-based system, and the mobile agents are sent carrying the proper instructions to reconfigure the jeopardized hosts.

This paper addresses a key issue that arises in run-time recomposition of software: the transfer of nontransient state between old components and their replacements. We focus on the concept of collateral change, which refers to the set of recomposition actions that must be applied atomically for continued correct execution of the system. We describe Perimorph, a system that supports compositional adaptation of both functional and nonfunctional concerns by explicitly addressing collateral change. The operation of Perimorph is demonstrated through the implementation and testing of a 2D/3D digital elevation mapping application that supports recomposition and handoff among networked devices with varying capabilities.

Epic Games provides a free game level editor with titles based on its Unreal engine. The editor provides a rich set of authoring tools that can be used to create fully interactive environments. This paper describes a tool that converts Unreal levels to web-ready environments in VRML and X3D, The paper also examines the similarities between first-person-shooter games and web 3D worlds, and discusses the implications of having a low-cost, fully featured virtual world authoring environment available for creating web 3D content.

The modified finite-difference time-domain(FDTD) method, generalized tobd-field/scattered-field(G-TF/SF) FDTD is applied to compote the response of interconnect illuminated by an external electromagnetic field. This method is also extended front 2-D to 3-D. The current distributions on the strips are presented and in good agreement with the data computed via the moment methods. The simulation result indicates that this method is fast and accurate for the infinite scatterer problem. The method to be fully developed intents to model and simulate the electromagnetic suscepitibility problems with an external excitation source. This paper will present the algorithm development and the preliminary results generated.

Dependence of output characteristics of electron beam from geometry of the emission channel, parameters of the electrode structure of plasma electron sources and concentration of emitting plasma has been calculated by computer simulation of electron-optical systems. It has been shown that dependence of electron beam characteristics on these factors is explained by the depth of penetration of plasma in emission channel and emitting surface form.

This paper proposes a Bayesian network (BN) model for distribution-system-reliability assessment and reassessment. The zone-based FMEA technique is applied to construct the BN model. During forward propagation of probabilistic information, load-point and system reliability indices are calculated And the weak points are identified during backward propagation for what-if studies. A dual isomorphic model is used to obtain outage probabilistic indices as well as outage frequency indices. The application of the proposed method to RBTS-Bus6 shows its superiority and validity.

In this paper we present the design of FolkMusic, a mobile peer-to-peer entertainment system. The work reported in this paper builds on the current trends towards: 1) edutainment software, 2) increase in use of peer-to-peer technologies, and, 3) the current trend towards mobile computing solutions. Further on, the research reported in this paper builds on prior research on "folk computing" for which mobile ad-hoc peer-to-peer solutions are a focal concern. Overall, this paper contributes to research on MANETs (Mobile Ad-hoc Networks) and peer-to-peer (P2P) computing by illustrating how mobile peer-to-peer technologies can be applied to both the area of entertainment as well as for educational purposes. Further on, the FolkMusic system contributes to current technical efforts made on ad-hoc networks by providing a good example of how Internet technologies and similar stationary and stable infrastructures can be combined with highly dynamic and wireless networks.
