RRR 1-2012 ON THE REPETITION-FREE SUBTRACTION GAMES AND VILE–DOPEY INTEGERS, Vladimir Gurvich Given two integers n ≥ 0 and k ≥ 3, two players alternate turns taking stones from a pile of n stones. By one move a player is allowed to take any number of stones k′ ∈ {1, . . . , k − 1}. In particular, it is forbidden to pass. Furthermore, it is not allowed to take the same number of stones as the op...

The morphometry of 187 cirques like forms is performed in the selected regions of Zagros Mountain with the use of GIS. The cirques like forms were delimitated manually and their headwall and floor boundaries were modified based on the classified slope map. The power law functions were fitted to 187 longitudinal cross-sections of the cirque like forms and their parameters were analyzed. All the ...

in this article, we discuss measure theoretic characterizations for weighted composition operators in some operator classes on $l^{2}(sigma)$ such as, $n$-power normal, $n$-power quasi-normal, $k$-quasi-paranormal and quasi-class$a$. then we show that weighted composition operators can separate these classes.

This study addresses a stochastic structure for generation companies (GenCoʼs) that participate in hydro-thermal self-scheduling with a wind power plant on short-term scheduling for simultaneous reserve energy and energy market. In stochastic scheduling of HTSS with a wind power plant, in addition to various types of uncertainties such as energy price, spinning /non-spinning reserve prices, unc...

nephrolithiasis was incidentally diagnosed in 2 arabian horses, a young foal and an adult mare, from maybod, yazd province, iran. the foal had bilateral neophrolithiasis, as multiple sand like stones in renal papillary area. large nephroliths were found in the left kidney of mare. prominent composition of those nephroliths was magnesium ammonium phosphate. risk factors and other aspects of neph...

introduction: the aim of this study was to investigate the scanning electron microscope (sem) analysis of tooth surface irradiated by different parameters of er:yag laser. methods: 15 caries-free extracted human third molars were used in this study. the teeth were put into 5 groups for laser irradiation as follows: group 1 (power: 2.5 w, energy: 250 mj); group 2(power: 3 w, energy: 300 mj); gro...

In order to ensure the quality of supply in the electric energy system the ancillary services frequency and voltage control are necessary. With regard to the ongoing decentralization of power supply, approaches are being investigated to provide those ancillary services by decentralized units some of which are highly volatile in power generation. This leads to the question of the reliability wit...
