Diffusion of knowledge is expected to be huge when agents are open minded. The report concerns a more difficult diffusion case when communities are made of stubborn agents. Communities having markedly different opinions are for example the Neocreationist and Intelligent Design Proponents (IDP), on one hand, and the Darwinian Evolution Defenders (DED), on the other hand. The case of knowledge di...

In this paper, we propose a dynamic economic dispatch (DED) model with sharing of responsibility for supply–demand balance under uncertain demands in a microgrid (MG). For developing the proposed model, an energy band operation scheme, including a tie-line flow (TLF) contraction between the main grid and the microgrid (MG), is constructed for preventing considerable changes in the TLFs caused b...

The fast-flux service network architecture has been widely adopted by bot herders to increase the productivity and extend the lifespan of botnets’ domain names. A fast-flux botnet is unique in that each of its domain names is normally mapped to different sets of IP addresses over time and legitimate users’ requests are handled by machines other than those contacted by users directly. Most exist...

When executing different real-time applications on a single processor system, one problem is how to compose these applications and guarantee at the same time that their timing requirements are not violated. A possible way of composing applications is through the resource reservation approach. Each application is handled by a dedicated server that is assigned a fraction of the processor. Using t...

In this paper we consider the problem of designing a mixed assembly–disassembly line for remanufacturing. That is, parts from the disassembly and repair of used products can be used to build “new” products. This is a problem common to many OEM remanufacturers, such as Xerox or Kodak. We study two main configurations, under the assumption that the disassembly sequence is exactly the reverse of t...

Description: Support to smallholder irrigation agriculture by virtue of establishing smalland medium-scale irrigation perimeters along the Eastern and South-Eastern slopes of Mt Kenya. In the first two phases (phase III ongoing, phase IV under preparation) approx. 2,700 smallholder farmers benefited from the establishment of 1,785 hectares of newly irrigated land (6 perimeters with altogether 4...

A peer-to-peer collaborative visualization system has been built that can support both traditional displays and 3D virtual reality hardware. The software is built around Sun’s Java3D graphics and JXTA peer-to-peer networking APIs, allowing two users to load VRML geometry files and manipulate their contents. Although this software takes advantage of VR hardware, it may be used between any two Ja...

Keeping an eye on the future upcoming demands for mobile applications, 3GPP has the target to enhance the downlink packet data rate in many folds. As a result, WCDMA specifications have been evolved with the addition of a new feature called HSDPA (High Speed Downlink Packet Access) in Release 5. The goal of HSDPA has been to increase the system capacity by increasing the data rate and reduce th...

Received 12 November 1986 Revised 1 March 1988 Gideon Y. Akavia has a Ph.D. in Computer Science from the University of California in Los Angeles. He was with the Faculty of the Israel Institute of Technology, and since 1980 has been with the Center for Military Analyses (CEMA), Haifa, Israel. He is presently visiting Stanford University, as a Science Fellow in the Center for International Secur...

In-stent restenosis, the maladaptive response of a blood vessel to injury caused by the deployment of a stent, is a multiscale system involving a large number of biological and physical processes. We describe a Complex Automata Model for in-stent restenosis, coupling blood flow, drug diffusion, and smooth muscle cell models, all operating on different time scales. The Haemodynamics is handled u...
