The heart rate variability (HRV) spectral parameters are classically used for studying the autonomic nervous system, as they allow the evaluation of the balance between the sympathetic and parasympathetic influences on heart rhythm. However, this evaluation is based on the definition of frequency bands that are found to be controversial because of possible changes in the frequency boundaries due to physiological factors or experimental conditions. We propose to overcome this difficulty by dynamically modelling the power spectrum as a two Gaussian shapes mixture. It appeared that this procedure was able to more accurately follow the exact parameters in the case of simulated data, in comparison with parameters estimation obtained with a rigid frequency cutting approach or with the ITSB algorithm [1]. Real data results obtained on a classical stand-test are also presented and discussed.

To exchange medical data between two distant locations is of paramount importance in a significant number of scenarios (emergency, developing countries, home care, training, etc.). This paper presents performance evaluation, through emulation and using real medical equipment, of a Telemedicine application including Electro-encephalographic (EEG) data, audio, video and text. All the application flows will be routed through an IP-based network emulator, which introduces the same effects of the transmission over a real satellite link, including a satellite segment which adopts the ETSI standard DVB-RCS EN301–790. The Telemedicine application aims to support a typical clinical exam, commonly used for the diagnosis of several neurological disorders, but with the neurologist located in a different place with respect to the patient. The paper describes in particular the setup and technical issues in case the application is used over a satellite network. Feasibility and performance evaluation, checked by the neurologist, are carried out using a DVB-RCS emulated environment (called SNEP), providing some remarks on the setup and comments on the obtained results.

Localization is an important component in many applications such as the promising Ultra-Wideband (UWB) wireless sensor network for medical treatment. For the majority of localization technologies, it is essential to measure the ranges between a target and several reference nodes before the target can be localized. Existing range estimation techniques rely on the measurements of time-of-arrival (TOA) and received-signal-strength (RSS) which suffer from environmental change. Dynamic environment such as human mobility can cause non-line-of-sight (NLOS) measurements which will significantly degrade the accuracy of range estimation. Therefore, range estimation methods are desired to be robust to NLOS measurements. In this paper, it is proposed to use hypothesis tests to identify whether there are NLOS measurements mixed in with the measurement dataset. For those NLOS corrupted measurement datasets, a new range estimation method based on a Log-normal model is found to be capable of reducing the range estimation error. Another advantage of this new range estimation method is that NLOS measurements are not required to be excluded from its analysis. However, simulation results show that the range estimation accuracy can be further improved if NLOS measurements are excluded.

Microwave techniques for biomedical applications aimed at cancer treatment or diagnosis, either by imaging or spectroscopy, are promising. Their use relies on knowledge of the dielectric properties of tissues, especially on a detectable difference between malignant and normal tissues. As most studies investigated the dielectric properties of ex vivo tissues, there is a need for better biophysical understanding of human tissues in their living state [1]. The paper deals with investigation of dielectric qualities of pure glucose, glucose in solutions like phantoms of biological tissues directing the attention at its manifestation at carcinoma cells investigation by means of microwaves. Simple and well-known theoretical formulas are used for unambiguous determination of complex permittivity. Experimental results from these investigations are given and their evaluation is presented.

In this paper, we extend our proposed scheme of cooperative communications based on Alamouti scheme which was aided by a single relay node to forward network coded bits to the destination. In this work, instead of a single relay node, we consider multiple relays forwarding network coded bits, of the information received from the cooperating users, to the destination. With analytical results on the outage probability, we show that the cooperative diversity gain of the proposed scheme increases linearly with m, the number of relay nodes assisting cooperating users by forwarding network coded bits of their information to the destination.

A Brain-Computer Interface (BCI) allows the direct communication between humans and computers by analyzing brain activity. The oddball paradigm allows detecting event-related potentials (ERPs), like the P300 wave, on targets selected by the user. While this paradigm provides the location of the P300 wave in the signal, its exact location remains a hypothesis and depends on the subject. This paper deals with the choice of the time segment for the signal analysis and its impact on the classification. A method for selecting the relevant part of the signal that contains the P300 wave is proposed. First, spatial filters are estimated for enhancing the signal. Second, a part of the enhanced P300 wave is selected based on its magnitude. This selection aims at providing an optimal start for the time window representing the P300 wave. Three window lengths are compared. We show that a window length of 500ms provides on average the best results, but the optimal window length should be set individually. The proposed technique has been validated on data recorded on 20 healthy subjects.

We develop a new sequence alignment called MTRAP by introducing a measure due to entangled correlation in two consecutive residues. We showed that the alignment accuracy could be improved by our approach. In the benchmark test by PREFAB 4.0, our method achieves the highest ranking compared with other methods such as ClustalW2, TCoffee and MAFFT.

The remarkable growing of the energy consumption from fossil fuels and the gases given off by them to the atmosphere promoting the greenhouse effect, has risen exponentially. In the last two years it has experienced an insignificant fall due to the financial crisis in several economic sectors. Moreover, it there had been a launching in the production of electric power from renewable energy sources, most of all wind energy and photovoltaic energy. Pressures from the public community as well as campaigns from respective governments and national and international institutions such as: Kyoto commitment promoting energy efficiency as a result of a decrease in the stores of primary energy and the perception of the climate change requires to set the target 20 20 20 up, in other words for next year 2020 to reduce by 20% the emission of CO2 and to generate by 20% of the produced electric power in renewable energy sources. Otherwise, in the telecommunication industry, the third economy in the world which is not free to these facts, the subscription's demands into mobile phone services and broadband connections are increasing exponentially. The main important energy source consumed by telecommunication operators is electric. Nevertheless, it has been proved that the energy consumption from a usual network of a mobile network operator varies between 1,5 TWh and 9TWh [7] per year, and nowadays it is estimated that the telecommunication's industry consumes about 1% of the global energy consume of the planet.

In a system of pulse-coupled oscillators with delays, inhibitory coupling assures synchronization and convergence if the oscillators are fully connected. This paper investigates inhibitory coupling in non-fully-connected networks by means of simulation. First, we show that an existing inhibitory coupling scheme does not perform well in random networks. Second, we propose a simple modification, which tends to improve the synchronizing behavior of inhibitory coupling.

Admission and power control schemes play important roles in deploying cognitive radio technology to cellular networks. In this paper, we propose a method to calculate the power scale factor, introduce two pre-admission control schemes, and reformulate the problem as a multidimensional knapsack problem. In addition, we propose a novel admission and power control scheme called JAPC-MKP. Simulation results show that our proposed JAPC-MKP can very closely approach the optimal results from the optimization software MOSEK, and greatly outperform the existing schemes in most cases.
