Backo algorithms are traditionally employed in multiple access networks, like Ethernet, to recover from packet collisions. In this paper, we propose and carry out the analysis for three types of link layer backo schemes{linear, binary exponential, geometric{on point-to-point wireless fading links, where packet errors occur non-independently. In such a scenario, the backo schemes are shown to ac...

Consensus trees are used in phylogenetics as summaries or representations of sets of source trees. Here we ask ‘How good are consensus trees?’ in the sense of how well do individual consensus trees represent the set of source trees for which they stand? There are many different consensus methods and various contexts in which they may be used (Swofford, 1991; Wilkinson, 1994; Leclerc, 1998). Con...

Membrane distillation (MD) has emerged as an important technology for applications in industries such as seawater desalination and wastewater treatment due to its low energy requirement and theoretically low fouling propensity. However, the main obstacle to obtain high separating efciency in MD lies on the availability of porous hydrophobic membrane that can withstand p...

In this paper we present the principle of learning by specialization within a cortically-inspired framework. Specialization of neurons in the cortex has been observed, and many models are using such \cortical-like" learning mechanisms, adapted for computational efciency. Adaptations will be discussed, in light of experiments with our cortical model addressing causality learning from perceptive ...

We present a di erential MSK receiver with coarse frame synchronization using a RSSI Signal and thus allowing the use of the capture phenomenon. The capture event is detected by an ML{derived circuit. Our investigations include all synchronization units allowing a tradeo between preamble length and implementation efciency. We provide a performance study including the e ect of quantization. The ...

Using liquid membrane and, in particular, supported liquid membrane (SLM) is a novel method of separation in comparison to other methods such as adsorption, extraction and ion exchange. SLM is a combination of simultaneous extraction and disposal whose high efciency and capability is proven by many studies. So far, many researchers have utilized SLM in various scientifc...

Central problems in path planning are obstacle avoidance and path optimisation. The aim of our work was to investigate the efciency of an Evolution Strategy for optimising robot parameters in both respects. We chose a simple model in order to highlight the effect of evolution as an optimisation procedure. In our model the robot has to reach given goals from a given starting position. In our sim...
