Othogonal frequency division multiplex-ing with a suitably chosen guard interval is a n effective means of eliminating intersymbol interference for high-rate transmission over fading dispersive channels. T i m e variations of t h e channel, however, lead t o a loss of subchannel orthogonality, resulting in interchannel interference (ICI). This article(More)
PURPOSE This study examined the effects of exercise-induced fatigue on soccer skills performed throughout simulated match play. METHODS Fifteen academy soccer players completed a soccer match simulation (SMS) including passing, dribbling, and shooting skills. Precision, success rate, and ball speed were determined via video analysis for all skills. Blood(More)
A ''book-embedding'' of a graph G comprises embedding the graph's nodes along the spine of a book and embedding the edges on the pages so that the edges embedded on the same page do not intersect. This is also referred to as the page model. The ''pagenumber'' of a graph is the thickness of the smallest (in number of pages) book into which G can be embedded.(More)
In a localized routing algorithm, node A currently holding the message forwards it to one or few neighbors based on the location of itself, its neighboring nodes and destination. Several localized routing algorithms for wireless networks were described recently, based on location information of nodes available via Global Positioning System (GPS). The(More)
Occipital visual evoked potentials (VEPs) were recorded in response to low-contrast, low spatial-frequency chromatic, and achromatic gratings. Fast Fourier Transform (FFT) and time-domain analysis were used to reveal differences in harmonic content and amplitude of chromatic and achromatic response components over a wide range of temporal frequencies. The(More)
The ability to maintain technical performances (i.e. skills) throughout soccer match-play is considered to be crucial in determining the outcome of competitive fixtures. Consequently, coaches dedicate a large proportion of time to practicing isolated skills, such as passing, shooting and dribbling. Unlike other elements that contribute to team-sport(More)
The use of recycled concrete aggregate (RCA) is recommended based on a review of literature that investigated the properties and characteristics of RCA, the physical properties of fresh and hardened concrete containing RCA, the mechanical behavior of concrete containing RCA, and special considerations for concrete pavements using RCA to achieve suitable(More)
Group work has the potential to be both educationally effective and resource efficient. It provides opportunities to set more integrative assessment tasks whilst also providing opportunities for the students to learn more than they would by simply responding to the coursework briefing sheet. Issues arise, however, with the necessity to individualise the(More)
Chromatic and achromatic visual function were investigated using psychophysical and evoked potential techniques in 32 patients with multiple sclerosis (MS) or optic neuritis. There was no evidence for either chromatic or achromatic vision being selectively damaged. There was, however, some evidence that demyelination of the optic nerve causes a visual(More)
