In order to cope with unpredictable problems, the concept of biologically inspired networks has been introduced, which provides a high degree of robustness and adaptability to computer networks. However, the performance of the network often relies heavily on the configurable parameters assigned during the deployment process, where end nodes cannot change these parameters during runtime to achieve the desirable performance. In this paper, we introduce a new method, called attractor perturbation (AP) allowing end nodes to influence the average of an observable performance metric at runtime without directly manipulating any optimal parameters of underlying protocols. An example application in this paper is a traffic distribution over multi-path routing protocol in MANETs, where the target variable is end-to-end delay. The approach to solve for the appropriate amount of management influence and simulation results are shown in this paper.","PeriodicalId":91990,"journal":{"name":"...

The algorithm uses soft output values of the channel decoder which are given as input of the cryptographic verification module. The criterion of standard verification becomes less strict, when the algorithm for correction and soft verification is introduced. Soft verification allows the correction of messages, if only some bits of the message and the MAC are modified. So, many disturbed messages, which cannot be corrected by repetition, can be recovered -- at the cost of trust in the message. This paper introduces the quantified unit of trust in a message and presents the results of simulations, showing a significant improvement of the acceptance rate of the cryptographic verification.","PeriodicalId":91990,"journal":{"name":"...

In this scheme of networking, specified bandwidth is reserved for each communication path based on bandwidth tables constructed by each terminal. This bandwidth reservation is desirable in diaster areas where rescue teams need to share wideband picture images of distant locations sent from rescue robots or human scouts. However, because process gain of associated CDMA operation is assumed to be high enough, unreasonable ra-diowave bandwidth is necessary for the system designs. The proposed method for bandwidth table construction regards CDMA interferences when the process gain is set arbitrary. With this method, system designs with reasonable radiowave bandwidth become possible. Simulations confirm the network performances with the proposed method.","PeriodicalId":91990,"journal":{"name":"...

Since most cell phones are nowadays equipped with cameras they can provide an easy way for blind and visually impaired people to obtain visual information about their environment. In this paper we present a banknote recognition system for our previously proposed mobile device, called the bionic eyeglass. We employ a recognition scheme based on the structural topology of banknotes that enables that the visual features detected are not joined in an ensemble classifier independently, but they are coupled via an excitation-inhibition model. We have shown that the technique outperforms classical ensemble classifiers.","PeriodicalId":91990,"journal":{"name":"...

In order to overcome this difficulty, in this paper, we propose a noncoherent MAP (maximum a posteriori) detector with very low complexity for orthogonally designed USTM (unitary space-time modulation) schemes. In addition, we show that the detected soft values are independent of the extrinsic information fed back from the turbo decoder. As a result, iterative detection and decoding between the noncoherent detector and the turbo decoder can be avoided without performance degradation. Compared to the scheme using the exhaustive-search-based noncoherent MAP detector, the proposed scheme achieves the same error performance, and has a much lower detection complexity.","PeriodicalId":91990,"journal":{"name":"...

Skin cancer detection at the earliest stage possible is vital to increase the chance of survival of the affected patient. Imaging in this field happens to be at the cross-roads. Skin cancer imaging can be visual in nature (nevoscope imaging, electron microscope, naked eye) or non-visual (optical coherence tomography (OCT), Raman spectroscopy). ABCDs is a set of rules that are the first step that is applied to determine the nature of a mole. Although extensively used as front line methodology for malignancy in moles, it is not deterministic in nature. Each of the techniques described in this paper analyze the samples of the skin lesion under the scanner in a varied way. The samples of the skin lession can be either a visual depiction or in the form of a cross-section. We have after extensive experimentation arrived at two different ways to analyze the samples obtained as a result of the imaging. For the sample that we have obtained as a result of the nevoscope visual imaging, the power spectra appears to be the most discriminative and effective way of classification as against the use of discrete wavelet transformation in case of the cross-sections obtained from OCT. The aim is to ultimately build an automated system that has the capability to discriminating and classifying the skin samples into three main classes; namely, benign, precancerous and malignant independent of the scanning methodology.","PeriodicalId":91990,"journal":{"name":"...

Depending on the patients' actual need for accommodation, the system autonomously adapts the refractive power of its integrated optical element in a way that the projection on the patients' retina results in a sharp image. As the Artificial Accommodation System is an active implant, its subsystems have to be supplied with electrical energy. Therefore an inductive power supply system will be developed which is able to autonomously power the Artificial Accommodation System over a period of 24h and can be recharged wirelessly. This Paper describes the design process of the coils needed for inductively transferring power to the implant. It can be shown that by means of optimization it is possible to transfer 50 mW of power to the interior of the Artificial Accommodation System.","PeriodicalId":91990,"journal":{"name":"...

This is due to the fact that hardware implementation is much constrained by the small size of the endoscope capsule and available power is also very limited. In this paper, we propose a very low complexity image coder for the wireless endoscope which operates within these constraints, with special emphasis on low bit rate performance. The scheme encodes the captured images frame-by-frame using simple DPCM (Differential Pulse Coded Modulation) coding, combined with multi-rate processing, dead-zone quantization and efficient run-length coding of the quantization indices.
