Pointed Conflict-Free Colouring of Digraphs
Volume 50, Issue 1 , June 2018, , Pages 119-131
Abstract
In a pointed conflict-free partial (PCFP) colouring of a digraph, each vertex has at least one in-neighbour with unique colour. In this paper, it is proved that PCFP $k$-colourability of digraphs is NP-complete, for any $k >0$. Nevertheless for ... Read Moreمدل سازی راکتور هیدروژناسیون روغن سویا

Abstract
Multi-criteria shortest path problems (MSPP) are called as NP-Hard. For MSPPs, a unique solution for optimizing all the criteria simultaneously will rarely exist in reality. Algorithmic and approximation schemes are available to solve these problems; however, the complexity of these approaches often ... Read Moreحلیل حسّاسیّت عوامل مؤثّر بر مدل‌سازی کانسار مس سونگون

Abstract
In this paper, transfinite element method is used to analyze the two dimensional thermoelasticity problems. A comparison is made between the thermoelastic analysis results of the classical theory and theories with one or two relaxation times (i.e. L-S and G-L theories), for the half space problem. Governing ... Read Moreکاهش بعد تصاویر فراطیفی از طریق خوشه بندی فازی باندها

Abstract
Thin-walled hollow steel columns, either circular or box shaped, are commonly used as piers in bridges. Recent earthquakes, e.g. Hyogoken-Nanbu or Kobe 1995, on the other hand have shown that these columns are vulnerable to damage when subjected to earthquake loading. This paper presents a new innovative ... Read Moreریز ماشینکاری PET با استفاده از لایه برداری شیمیایی در حضور

Abstract
In this paper, we report vertical etching of poly-ethylene-terephtalate plastic substrates by means of a chemical solvent and in the presence of ultra-violet illumination. Since the PET substrate is not dissolved in solvent without a UV source, only the desired areas with proper opening for UV exposure ...

Abstract
Induction Motor especially the squirrel cage type of this motor plays important role in industry. According to the application type, this motor place against various stresses that are caused failure in the motor. The most common failure is related to the Stator winding. Among these failures are turn-to-turn, ... Read Moreاثر عامل حالت در بهبود پیش بینی رخداد نوار برشی در خاک های دانه ای

Abstract
The capability of sand constitutive models is remarkably improved by taking into account the effect of soil state in their formulations. In this study, it has been shown that considering the effect of soil state leads to better simulation of soil instability of shear banding type. To this aim, constitutive ...

Abstract
In this paper we restrict every set splitting problem to the special case in which every set has just three elements. This restricted version is also NP-complete. Then, we introduce a general conversion from any set splitting problem to 3-set splitting. Then we introduce a randomize algorithm, and we ... Read MoreTenacity and some related results
