This paper deals with hybrid sliding mode control of multicell power converter. It takes into account the hybrid aspect of the conversion structure which includes the converter continuous and discrete states. The basic idea used in this paper is to consider the interconnected systems that represent the hybrid model and to generate commutation surfaces based on a Lyapunov function that satisfies...

We study the coordinated reception amongst multiple base stations (BS) in the uplink cellular system, where each mobile station (MS) is served by an associated multiple BS set (MBS). Under the individual signal-to-interference-plus-noise ratio (SINR) constraint per MS, power control and receive beamforming are jointly optimized with adaptive MBS selection to minimize the total transmit power. A...

In this work, we look at spatially dependent diffusion of growth inhibitory factor (GIF) in multicell spheroids. The production GIF is taken to be time-dependent and heterogeneous within the spheroid. Using a semigroup approach, investigate dynamical behaviour presented mathematical model. Firstly, existence positivity solutions. Secondly, with time-independent source GIF, prove unique steady s...

Binding of several nitroheterocycles by mammalian cells is a function of the ambient oxygen concentration; anoxic single cells bind up to 10 times as much of these drugs as do aerobic cells. We thus hypothesized that fluorescent nitroheterocyles could be used to quantitate the fraction of hypoxic cells in multicell systems, and this was tested in multicell spheroids using a relatively nontoxic ...

We address the optimization of the sum rate performance in multicell interference-limited singlehop networks where access points are allowed to cooperate in terms of joint resource allocation. The resource allocation policies considered here combine power control and user scheduling. Although very promising from a conceptual point of view, the optimization of the sum of per-link rates hinges, i...

The behavior of longitudinal wakefields of very short bunches, excited in in multicell accelerating structures has been studied. Computations were performed in structures proposed for future linear colliders (like TESLA, SBLC and NLC) for bunch lengths down to 50 micrometers. The loss factor, which gives the global energy loss of the bunch, and the profile of the wake function, which is of majo...
