The demand for wireless resources is increasing at high pace. Heterogeneous networks (HetNets), i.e., network composed by base stations (BSs) with different coverage area, are useful solutions to cope with this increased demand. Previously, we proposed a handover (HO) algorithm based on users velocity, users place, users received power strength from BSs and traffic load of BSs. Due to difficult...

The purpose of the present study was to examine the relationships between bat swing speed (BSS), muscle thickness, and muscle thickness asymmetry in collegiate baseball players. Twenty-four collegiate baseball players participated in this study. Maximum BSS in hitting a teed ball was measured using a motion capture system. The muscle thicknesses of the trunk (upper abdominal rectus, central abd...

UNLABELLED Background. It was hypothesized that the rate of wound closure and the number of grafts required will be the same when treating diabetic foot ulcers with TheraSkin®, a cryopreserved split-thickness skin allograft (SSA), as compared to Apligraft®, a bioengineered skin substitute (BSS). METHODS A prospective study using sequentially enrolled patients seen in a large podiatric practi...

While the deployment of base stations (BSs) becomes increasingly dense in order to accommodate the growth in traffic demand, these BSs may be under-utilized during most hours except peak hours. Accordingly, the deactivation of these under-utilized BSs is regarded as the key to reducing network power consumption; however, the remaining active BSs should increase their transmit power in order to ...

Blind source separation (BSS) and independent component analysis (ICA) are generally based on a wide class of unsupervised learning algorithms and they found potential applications in many areas from engineering to neuroscience. A recent trend in BSS is to consider problems in the framework of matrix factorization or more general signals decomposition with probabilistic generative and tree stru...

PURPOSE To develop a safe, noninvasive, noncontact, continuous in vivo method to measure the dehydration rate of the precorneal tear film and to compare the effectiveness of a viscoelastic agent in maintaining the precorneal tear film to that of a balanced salt solution. METHODS Software was designed to analyze the corneal reflection produced by the operating microscope's coaxial illumination...

To understand the spatial deployment of base stations (BSs) is the first step to facilitate the performance analyses of cellular networks, as well as the design of efficient networking protocols. Poisson point process (PPP) has been widely adopted to characterize the deployment of BSs and established the reputation to give tractable results in the stochastic geometry analyses. However, given th...

Over the last ten years blind source separation (BSS) has become a prominent processing tool in the study of human electroencephalography (EEG). Without relying on head modeling BSS aims at estimating both the waveform and the scalp spatial pattern of the intracranial dipolar current responsible of the observed EEG. In this review we begin by placing the BSS linear instantaneous model of EEG wi...

This paper presents a co-operation technique of channel assignment (CA) for indoor base stations (BSs). Indoor BSs are most of the time deployed by users in an ad-hoc manner which makes prior network planning by network operators impossible. If the same pool of radio resources (e.g channels) is used by close BSs, co-operation between these BSs is vital for resolving problems such as interferenc...

We investigate optimal geographical caching in heterogeneous cellular networks, where different types of base stations (BSs) have different cache capacities. The content library contains files with different popularities. The performance metric is the total hit probability. The problem of optimally placing content in all BSs jointly is not convex in general. However, we show that when BSs are d...
