The optic ow eld is deened as preserving the intensity along ow-lines. Due to singularities in the image at xed time, poles are created in the optic ow eld. In this paper we describe the generic types of ow singularities and their generic interaction over time. In a general analytic ow eld, normally the topology is characterised by the points where the ow vanish again subdivided into repellers,...

Gradient methods are widely used in the computation of optical ow. We discuss extensions of these methods which compute probability distributions of optical ow. The use of distributions allows representation of the uncertainties inherent in the optical ow computation, facilitating the combination with information from other sources. We compute distributed optical ow for a synthetic image sequen...

We introduce the maximumskew-symmetric ow problem which generalizes ow and matching problems. We develop a theory of skew-symmetric ows that is parallel to the classical ow theory. We use the newly developed theory to extend, in a natural way, the blocking ow method of Dinitz to the skew-symmetric ow case. In the special case of the skew-symmetric ow problem that corresponds to cardinality matc...

A novel hybrid organic-inorganic molecular solid, 1-(4-methoxyphenyl)piperazinium (1–4MPPip) tetra(isothiocyanate)cobalt monohydrate (1–4MPPip)4[Co(NCS)4]2•H2O (I), was prepared using a slow evaporation growth technique at room temperature and characterized by elemental analysis, X-ray crystal structure, spectroscopic computational studies. The structural analysis reveals that the solid crystal...

The paper presents an overview of the parallel computingmodels, architectures, and research projects that are based on asynchronous instruction scheduling. It starts with pure data ow computing models and presents an historical development of several ideas (i.e. single-token-per-arc data ow, tagged-token data ow, explicit token store, threaded data ow, large-grain data ow, RISC data ow, cycle-b...

In the current state of huge waste production and energy crisis, there is a need to find additional alternate resources options for management. The present study was designed measure potential different fruit wastes serve as substrate lipid accumulation in oleaginous bacteria. For this purpose, three novel bacterial strains (AF3, KM1 KM10) isolated from crude oil samples were systematically com...

In order to meet the massively increasing requirements of big-data applications, data centers (DCs) are key infrastructures cope with associated demands, such as high performance, easy scalability, low cabling complexity and power consumption. Many research efforts have been dedicated traditional wired center networks (DCNs). However, DCNs’ static rigid topology based on optical cables signific...

Bu çalışmanın amacı; Samsun ilindeki Altınkaya Baraj Gölü (ABG) ve Bafra Balık Gölleri (BBG)’nden elde edilen Cyprinus carpio örneklerinin otolitlerinin morfometrik özellikleri, otolit özellikleri-balık boyu arasındaki ilişkileri şekil indekslerinin analiz edilerek lokaliteler varyasyonların saptanmasıdır. Gerçekleştirilen analizlerde toplamda 109 (Altınkaya (N=59) Gölleri’nde (N=50)) birey değ...
