Centroidal Voronoi tessellations (CVT’s) are special Voronoi tessellations for which the generators of the tessellation are also the centers of mass (or means) of the Voronoi cells or clusters. CVT’s have been found to be useful in many disparate and diverse settings. In this paper, CVT-based algorithms are developed for image compression, image segmenation, and multichannel image restoration a...

Wheel loader transmissions are commonly based on a torque converter and an automatic gearbox. This solution is mechanically robust and well suited for the typical operation of the machine, but the fuel efficiency is low at some modes of operation. One proposed improvement is to replace the present transmission with a multi-mode power-split CVT (MM-CVT). This paper compares the fuel saving poten...

Cortical venous thrombosis (CVT) mostly occurs due to a hypercoagulable state. Infection- related CVT is very rare and medical emergency associated with high mortality rate. It has been described bacterial fungal infections; but only few isolated case reports of tubercular meningitis (TBM) exist. Only six documentations CVT, as complication TBM, exist in the literature. Here, we report young gi...

This study characterizes the receptor binding and functional effects of CVT-3619 [2-{6-[((1R,2R)-2-hydroxycyclopentyl)-amino]purin-9-yl}(4S,5S,2R,3R)-5-[(2-fluorophenylthio)methyl]-oxolane-3,4-diol], a novel N(6)-5' -substituted adenosine analog and A(1) -adenosine receptor (A(1) AdoR) agonist, on rat epididymal and inguinal adipocytes and on the isolated heart and compares these effects with t...

Methods: 146 patients with breast cancer, received 4-6 cycles of CT with FAC regimen. The complex of clinical, laboratory and instrumental investigations was performed to the patients from this group. The main evaluated toxicity types were hematological, gastrointestinal (GIT), liver and cardiovascular toxicity (CVT). Results: GIT was more common in patients aged less than 50 years old (100% vs...

Abstract Thrombosis of the cerebral veins and sinuses (CVT) is a distinct cerebrovascular disorder that, unlike arterial stroke, most often affects children young adults, especially women. In this review, we will summarize recent advances on knowledge patients with CVT.

This paper presents the results of a comparative investigation into effects ignition method on ballistic properties three types propellants: single-base propellant, double-base propellant and low vulnerability (LOVA) as determined via closed vessel tests (CVT). Conventional gunpowder plasma jet methods were used. The influence values characteristics obtained in CVT was analysed. It found that h...
