The high-intensity heavy-ion beams of the FAIR accelerators, together with the planned Compressed Baryonic Matter (CBM) experiment [1], offer unique possibilities to produce and to investigate baryonic matter at highest densities in the laboratory. According to calculations, baryon densities of up to 10 times saturation density (comparable to the ones in the inner core of neutron stars) and ene...

in this paper we focus on a continuously deteriorating two units series equipment which its failure can not be measured by cost criterion. for these types of systems avoiding failure during the actual operation of the system is extremely important. in this paper we determine inspection periods and maintenance policy in such a way that failure probability is limited to a pre-specified value and ...

Fast skeletal and cardiac troponin C (TnC) contain two high affinity Ca2+/Mg2+ binding sites within the C-terminal domain that are thought to be important for association of TnC with the troponin complex of the thin filament. To test directly the function of these high affinity sites in cardiac TnC they were systematically altered by mutagenesis to generate proteins with a single inactive site ...

Development and production of coalbed methane involves the production of large volumes of water. The salinities and sodium adsorption ratios of coalbed methane (CBM) water from the Powder River Basin range from 370 to 1,940 ppm and 5.6 to 69 respectively. Surface discharge of CBM water can create serious environmental problems; subsurface injection is generally viewed as economically nonviable....

روش های شبیه سازی زمین اماری بعنوان یک ابزار قوی برای براورد تئزیع فضایی عدم قطعیت زمین شناختی در اکتشاف معادن شناخته شده داست.استفاده از این روش در صنعت معدنکاری فلزی به فراوانی متداول و در معدنکاری زغال کم بوده است.کانسار زغالسنگ پروره iii طبس در قسمت شرق ایران مرکزی واقع شده و دارای 5 لایه به نامهای c1, c2, b1, b2, d می باشد که از میان لایهc1به علت داشتن ساختمانی ساده ،ضخامت متوسط نسبتا بالا...

The presence of methane in coal mines is one of the major problems in underground coal mines. Every year, in underground coal mines, a lot of casualties due to outbursts and explosions of methane gas is occurring. Existence of this gas in the mines not only creates a difficult and dangerous situation for work but also makes it more expensive. The release of this gas to the air causes a further ...

We report a new strategy that uses N-trimethylsilyl (N-TMS) amine to mediate controlled ring-opening polymerization of amino acid N-carboxyanhydrides (NCAs). This polymerization proceeds via a unique, trimethylsilyl carbamate (TMS-CBM) propagating group that results from the cleavage of the Si-N bond of N-TMS amine followed by NCA ring opening. Propagation of the polypeptide chains proceeds thr...

Œis paper introduces the combinatorial Booleanmodel (CBM), which is defined as the class of linear combinations of conjunctions of Boolean aŠributes. Œis paper addresses the issue of learning CBM from labeled data. CBM is of high knowledge interoperability but naı̈ve learning of it requires exponentially large computation time with respect to data dimension and sample size. To overcome this comp...

This paper proposes an improved color barycenter model (CBM) for road sign detection. The previous version of CBM can find out the colors of road-sign (RS), but its accuracy is not high enough for magenta and blue region segmentation. The improved CBM extends the barycenter distribution to cylinder coordinate and takes the number of colors in every point into account. Then the K-means clusterin...

This paper concerns control and performance evaluation for stochastic network models. Structural properties of value functions are developed for controlled Brownian motion (CBM) and deterministic (fluid) workload-models, leading to the following conclusions: Outside of a null-set of network parameters, (i) The fluid value-function is continuously differentiable. Under further minor conditions, ...
