The aim of our work was to rate the suitability of different array combining algorithms to the special requirements of the UTRA/FDD uplink. After formulating the algorithms, we assess their bit error performance in a modified vehicular B channel that is spatially inhomogeneous. The bit error ratios in different situations are presented together with some considerations about the computational c...

In this paper, we propose an evolution of adaptive power control algorithms for Universal Mobile Telecommunications System (UMTS). The proposed mechanism uses an adaptive power step to carry out with high fluctuations in the radio interface. Furthermore, we propose the integration of a stabilization zone where the transmitted power is kept constant to reduce oscillations around the target QoS l...

Models of faulty components or processes may either be used on-line as part of a fault detection and diagnosis (FDD) system or may be used in simulations to train or test FDD procedures. Some faults may be modelled by choosing suitable values of the parameters of fault free models, whereas other faults require specific extensions to fault free models. An example of the modelling of various faul...

The physiological mechanism of functional constipation (FC) includes defecatory disorders and delayed colon transit. About 18% to 68% constipated patients may have rectal hyposensitivity (RH). We performed this study to investigate the association between RH and functional defecatory disorder (FDD) as well as that between RH and delayed colon transit in FC patients.A total of 218 FC patients we...

We have studied the effects of gas density inhomogeneities on the escape of ionising Lyman continuum (Lyc) photons from Milky Way-type galaxies via 3D numerical simulations using the Monte Carlo radiative transfer code CRASH (Ciardi et al. 2001). To this aim a comparison between a smooth Gaussian distribution (GDD) and an inhomogeneous, fractal one (FDD) has been made with realistic assumptions...

Differential display and DNA microarray have emerged as the two most popular methods for gene expression profiling. Here, we developed a multicolor fluorescent differential display (FDD) method that combines the virtues of both differential display in signal amplification and DNA microarray in signal analysis. As in DNA microarray, RNA samples being compared can be labeled with either a red or ...

An autosomal dominant mutation in the BRI2/ITM2B gene causes familial Danish dementia (FDD). Analysis of FDD(KI) mice, a mouse model of FDD genetically congruous to the human disease since they carry one mutant and one wild-type Bri2/Itm2b allele, has shown that the Danish mutation causes loss of Bri2 protein, synaptic plasticity and memory impairments. BRI2 is a physiological interactor of Aβ-...

Existing methods addressing automated fault detection and diagnosis (FDD) for vapor compression air conditioning system have good performance for faults that occur individually, but they have difficulty in handling multiple-simultaneous faults. The decouplingbased (DB) FDD method explicitly addresses diagnostics for multiple-simultaneous faults for the first time. This paper is the second part ...

Massive MIMO is one of the key technologies in future generation networks. Owing to their considerable spectral and energy efficiency gain, massive MIMO systems provide the needed performance to cope with the ever increasing wireless capacity demand. Nevertheless, the number of scheduled users stays limited in massive MIMO systems both in TDD and FDD modes. This is due to the limited time slot ...

We investigated the feasibility of the coexistence of CDMATDD micro cells under a CDMA-FDD macro cell network with both sharing the same frequency band. A dynamic channel allocation (DCA) algorithm decides on the basis of mutual interference which FDD band is to use for the micro cell TDD channel. On the assumption of giving the macro cell higher priority we investigated the lower bound probabi...
