The aims of this study are to investigate muscular fatigue and to propose a new fatigue index based on the continuous wavelet transform (CWT) which is compared to the standard fatigue indexes from literature. Fatigue indexes are all based on the electrical activity of muscles (electromyogram

� in terms of idempotent-generated regular semigroup E, with a medial idempotent u, and of the orthodox semigroups with identity S, such that ES ( ) � u E u. In that paper M. Loganathan has also shown, that every regular semigroup S with a medial idempotent u, can be described in terms

novel framework for modeling multivalued motion fields, and propose an energy minimization formulation with smoothing terms and terms implementing velocity model competition. We illustrate the capabilities of this approach on synthetic and real sequences.

such a reduction is possible. Along our development, we present a unification of the existing SP algorithms in terms of a probabilistically interpretable iterative procedure — weighted Probabilistic

and Methods: The study included 21 patients with VBI (aged 31-76; mean 61.0 ± 10.5 yrs). We administered a 50 mg oral dose of sildenafil citrate to all patients. Next, we measured the peak systolic velocity (Vmax), end diastolic velocity (Vmin), resistive index (RI), pulsatility index (PI), diameter, area

the performance of the proposed scheme, the knowledge of the second-order channel statistics is exploited to design long-term beamforming coefficients through maximizing the receiver signal-to-noise ratio (SNR) with appropriate constraints. This maximization problem is approximated by a convex feasibility problem

Energy harvesting (EH) has recently emerged as a promising technique for green communications. To realize its potential, communication protocols need to be redesigned to combat the randomness of the harvested energy. In this paper, we investigate how to apply relaying to improve the short-term

of these approaches and offer a way to visualize the tradeoff between complexity of the detection and the achievable power efficiency using “complexity-power diagrams”. We conclude that the so-called sphere decoder algorithm is very attractive in terms of average complexity, while for low and constant processing

While contributory group key agreement is a promising solution to achieve access control in collaborative and dynamic group applications, the existing schemes have not achieved the performance lower bound in terms of time, communication and computation cost. In this paper we propose a contributory
