This paper presents the real-time implementation of wavelet-based Advanced Combination Encoder on PDA platforms for cochlear implant studies. Three real-time implementations using the conventional FFT, our previous recursive DFT, and the wavelet transform are compared in terms of computational complexity, processing time and fixed-point accuracy. The results obtained show that this new real-time implementation...
Cochlear implant patients often complain about their difficulty in understanding speech in noisy environments. Currently a fixed noise suppression algorithm is used in cochlear implants regardless of the characteristics of the speech or noise environment. Access to an intelligent mechanism to determine the noise environment on-the-fly in order to automatically switch between different noise suppression...
In our ongoing research work, we focus on how to amalgamate technology with organic farming. In this paper, we present a case study of using temperature sensor-actuators to monitor the temperature of the habitat of the worms used for vermiculture, a very vital stream in the realm of organic farming. `Vermiculture' meaning artificial rearing or cultivation of worms is a scientific process used to make...
This event-condition-action(ECA) rule description language for Web Services(named WS-ECA) is the latest buzzword in the realm of autonomous, intelligent agent based Web Service oriented computing (AWSOC). This rule description language supports interactions among service oriented, heterogeneous devices in a pervasive computing environment. It is based on ECA rules, which are embedded in distributed...
Computer Network Monitoring is an evergreen field of challenges. The recent advent of Cloud Computing, in the realm of `New Generation Networks', opens a whole new field of envisaging and implementing at least two of its aspects, namely `Software as a Service(SaaS)'and `Platform as a Service(PaaS)' in the field of Network Management(NM). In this paper, we present the design and implementation of a...
The present paper describes the design of two stimulators (bench-top and portable) which can be used for animal studies in cochlear implants. The bench-top stimulator is controlled by a high-speed digital output board manufactured by National Instruments and is electrically isolated. The portable stimulator is controlled by a personal digital assistant (PDA) and is based on a custom interface board...
Service Oriented Computing (SOC) is the fast emerging successor of the Object Oriented Computing design paradigm. Web Services technology, which is considered as an implementation of the SOC model, has had an incredible acceptance but tumultuous growth. This apparent chaos is due to its inherent lack of flexible cooperation strategies, generic service model and weak semantic description, mainly when...
More than a decade ago, MA(mobile agents) were introduced for NM(network management) of distributed computer networks in tandem with the design paradigm of code-shipping the agents to remote node, where they are programmed to collect, analyze and process data locally. However, even today, most networks employ SNMP (simple network management protocol), an inherently client-server based stable and proven...
This paper presents a real-time and interactive implementation of the recursive Fourier transform approach on PDA platforms for cochlear implant signal processing applications. PDA platforms provide a cost-effective and portable platform for cochlear implant studies. The computational complexities of the two commonly used signal processing strategies that are being used in commercial cochlear implants...
The design of feeders for castings has been mostly based on empirical rules, heuristics and past experience. This paper presents a novel approach to the problem by augmenting genetic algorithms with CAD to optimize the feeder dimensions. The synergy of CAD and genetic algorithms generates a class of optimal feeders that also satisfy the standard criteria laid down in literature. A CAD platform is...
