We study the optimal design of graph filters (GFs) to implement arbitrary linear transformations between graph signals. GFs can be represented by matrix polynomials of the graph-shift operator (GSO). Since this operator captures the local structure of the graph, GFs naturally give rise to distributed operators. In most setups the GSO is given, so that GF design consists fundamentally in choosin...

Recent technological advances have accelerated a renaissance in usage of non-geostationary (non-GSO) communication satellites in provision of various services domestically and globally. Early ventures into communication satellites have used satellites in low Earth orbits. The main reasons for this mode of operation were that the booster technology was not available to lift satellites into a hig...

The aim of the study was to determine microhardness of high- and low-viscosity bulk-fill composite resins and compare it with conventional composite materials. Four materials of high-viscosity were tested, including three bulk-fills: QuiXfi l (QF), x-tra fi l (XTF) and Tetric EvoCeram Bulk Fill (TEBCF), while nanohybrid composite GrandioSO (GSO) served as control. The other four were low-viscos...

In this chapter we present the design and optimization of GPU implementations of two popular chemical similarity techniques: Gaussian shape overlay (GSO) and LINGO. GSO involves a data-parallel, arithmetically intensive iterative numerical optimization; we use it to examine issues of thread parallelism, arithmetic optimization, and CPU-GPU transfer overhead minimization. LINGO is a string simil...

The means of achieving full duplex broadband access to either the home or office has been the focus of much research and entrepreneurial development in the past 5 years. This is the so-called “last mile” problem. One approach is duplex access to either a geostationary earth orbit (GSO) or non-GSO satellite, through a relatively small satellite dish located at each home or office. This scenario ...

 Abstract—This paper proposes new adaptive tree search detection with variable path expansion based on Gram-Schmidt (GS) orthogonalization (GSO) in MIMO systems. We adopt the GSO procedure to reduce the channel matrix instead of the QR-decomposition in the conventional QRM-MLD. This detection scheme combined the GSO reduction with the M-algorithm, what we call GSM-MLD, can achieve near-ML perf...

Edible coatings are traditionally used to improve food appearance and conservation due their environmentally friendly nature. In this study fresh cut (halved pitted) plum (var. Stanley) fruits were coated by chitosan grape-seed-oil (GsO) nanoemulsion. Physical, physico-chemical, microbiological sensorial properties examined 3 times during 9 d refrigeration storage. The control probes wasted saf...

The purpose of this study was to evaluate the effects grape seed oil (GSO) supplementation broilers fed polyunsaturated fatty acids (PUFA)-enriched diets on growth performance, color, texture, acid content and lipid peroxidation meat. 4-week feeding trial conducted 120 Cobb 500 broilers, assigned three groups housed in an experimental hall permanent wood shaves litter. GSO tested as source natu...
