Merging the adaptive networks with the free space optical (FSO) communication technology is a very interesting field of research because by adding the benefits of this technology, the adaptive networks become more efficient, cheap and secure. This is due to the fact that FSO communication uses unregistered visible light bandwidth instead of the overused radio spectrum. However, in spite of all ...

In this paper we survey some results concerning the impact of faulty environments on the solvability and complexity of communication tasks. In particular, we focus on deterministic models of faults in synchronous networks, and show how different variations of the model influence the performance bounds of broadcasting algorithms.

It is well-known that taking into account communications while scheduling jobs in large scale parallel computing platforms is a crucial issue. In modern hierarchical platforms, communication times are highly different when occurring inside a cluster or between clusters. Thus, allocating the jobs taking into account locality constraints is a key factor for reaching good performances. However, se...

In this paper we describe Tornado, which we teach in our software engineering project courses. Tornado is a new process model that combines the Unified Process with Scrum elements. The Tornado model focuses on scenario-based design starting with visionary scenarios funneling down to demo scenarios. Tornado o↵ers models for a broad range of activities. In addition to formal models used for analy...

A family of information theoretic models of communication was introduced more than a decade ago to explain the origins of Zipf’s law for word frequencies. The family is a based on a combination of two information theoretic principles: maximization of mutual information between forms and meanings and minimization of form entropy. The family also sheds light on the origins of three other patterns...

1 We describe the physics analogies used in a model of latency in computer communication and protocols. The communication model describes state imprecision as induced by message latency, and is based on physical models of particle interaction. Virtual particle effects are emulated through the use of conditional messages that reduce perceived latency while requiring additional bandwidth and acti...

Standard performance evaluations of communication networks focus on the technology layer where protocols define precise rules of operations. Those studies assume a model of network utilization and of network characteristics and derive performance measures. However, performance affects how users utilize the network. Also, investments by network providers affect performance and consequently netwo...

The collaborative nature of communication has been demonstrated by research on the increased efficiency (Hupet & Chantraine, 1992) and the adaptive behavior (Giles, Mulac, Bradac, & Johnson, 1987) of interacting pairs, but these two lines of research have never been explicitly related. This paper reports empirical results showing that adaptively matching word use can increase communication effi...

overuse of chemical inputs and inappropriate use of water resources have caused unsustainability in most agricultural regions of marvdasht county in fars province. for an attainment of sustainable production of wheat, it is necessary to design appropriate communicational models for agricultural inputs and for water optimum usage, however, reviewing agricultural development literature revealed t...
