Maintaining the utility of learned knowledge using model-based adaptive control
… learning both describe a common behavior of machine learning methods: the eventual degradation of performance due to increasing amounts of learned knowledge. Plotting the performance of the changing knowledge during execution of a machine learning method (the performance response) reveals …

Double linked backbone ring interconnected network
… Grillo showed that all desirable characteristics of IEEE 802.2 and 802.5 protocols for a single token ring are severely degraded in an interconnected token ring network. In order to address the problem, Bux and Grillo suggested a method of dynamically adjusting the size of windows depending on the …

Implementation of a variable rate vocoder and its performance analysis
The use of Code Division Multiple Access (CDMA) technology for cellular radio and personal communications has ushered in a new era wherein the benefits of CDMA can be directly applied to voice transmission. In particular, the resistance to multipath and graceful degradation of performance (voice …

Post-Activation Potentiation: Decay or Fatigue Delay
… potentiation has been shown to improve jumping performance and other ballistic activities. The improvements in performance have been attributed to four main mechanisms, but the most important mechanism to the current study is the improvement in neural activity that leads to greater levels of …

Reliability Assessment of Rolling Piston Rotary Type Compressos
The performance of a compressor changes during its lifetime, depending on various parameters such as operating conditions, type of the compressor, working fluid and type of the oil being used. Most performance degradation of the compressor is due to wear on the moving mechanical parts inside the …

Binaural sound source localization using machine learning with spiking neural networks features extraction
… binaural hearing systems are able take advantage of a variety of cues to localise sound-sources in a 3D space using only two sensors. This work presents a bionic system that utilises aspects of binaural hearing in an automated source localisation task. A head and torso emulator (KEMAR) are used to …

Study of Visual Clutter in Geographic Node-Link Diagrams
An increasing amount of geographic data is now freely available on the Internet, and this number is expected to increase as monitoring systems and sensors are becoming a ubiquitous part of our environment. A substantial subset is structured as networks (or graphs). Notable examples are …

Design of low-power digital circuits in the sub-threshold domain
The demand of low power consumption in microelectronics circuits has increased significantly as submicron technologies scale down. Battery operated portable applications are in high demand across the industries such as automotive, medical, MEMS, telecommunication and so on. Subthreshold operations …

Coating and filling of nanometer-scale structures using chemical vapor deposition
Void-free filling of high aspect ratio (AR = 3 to 10) structures, such as trenches or vias, is necessary in nanoscale device fabrication. Examples include shallow trench isolation, metallization, and reverse tone patterning in integrated circuits and optical waveguides in photonic devices. …

Removal of Organic Micro-Pollutants from Water Using Sewage Sludge Based Composite Adsorbents
<p>Millions of tons of sewage sludge, waste oil sludge and fish waste are produced annually, and improper treatment/disposal of these wastes have resulted in numerous environmental issues. On the other hand, these wastes are rich in organic materials, metals, and inorganic minerals and could be …
