An oriented graph is a directed graph without any cycle of length at most 2. To push a vertex of a directed graph is to reverse the orientation of the arcs incident to that vertex. Klostermeyer and MacGillivray defined push graphs which are equivalence class of oriented graphs with respect to vertex pushing operation. They studied the homomorphism of the equivalence classes of oriented graphs w...
In the present study, field oriented control of step motor implementation has been analyzed sothat it can make a Sensorless control. Efficiency and Facilities of step motor is more than othertypes of electromotor. Therefore, the numbers of mechanisms and different types of turning canbe made into them. Also controlling these motors is easier than other available motors. Steppingmotor has been d...
We completely determine, up to homeomorphism, which simply connected compact oriented 4-manifolds admit scalar-flat, anti-selfdual Riemannian metrics. The key new ingredient is a proof that the connected sum CP2#CP2#CP2#CP2#CP2 of five reverse-oriented complex projective planes admits such metrics.
The problem-oriented approach is one of the efficient methods of “contemplation in Quran”. This approach is applied as opposed to the subject-oriented and concept-oriented approaches. Historical analysis of the commentators’ appeal to the verse 97 Surah An-Nahl shows that lack of having the problem-oriented approach has led to the fact that many of them ignored this verse without making any com...
The aim of this research was to predict stress coping strategies based on primary maladaptive schemas and spiritual intelligence in the mothers of intellectually disabled students. The current research is part of applied research in terms of its purpose and correlational studies in terms of method. The statistical population includes all the mothers of mentally retarded students in the age rang...
Web-services have become a governing technology for Service Oriented Architectures due to reusability of services and their dependence on other services. The evolution in service based systems demands frequent changes to provide quality of service to customers. It is realised by different researchers that evolution in service based systems may degrade design and quality of service and may gener...
سابقه و هدف: بیماران مبتلا به تالاسمی ماژور برای زنده ماندن باید به طور مداوم خون تزریق نمایند.تزریق مداوم خون به بیماران تالاسمی ماژور موجب مواجه شدن سیستم ایمنی بیماران با طیف وسیعی از آنتی ژنهای موجوددر سطح گلبولهای قرمز تزریق شده ودر نتیجه تولید الوانتی بادی مینماید. تزریق خون به بیماران الوایمو نیزه ممکن است مشکلاتی جدی از جمله واکنشهای همولیتیک تاخیری به همراه داشته باشد .در نتیجه شناسای...
this paper presents an appropriate categorization of business processes in order to study the different aspects of knowledge management for each kind of business processes. in this categorization, business processes are classified into the four categories including work-flow oriented, decision oriented, information oriented and motivation oriented. then, the special attributes and knowledge man...
We investigate the optimization and evaluation of queries with universal quan-tiication in the context of the object-oriented and object-relational data models. The queries are classiied into 16 categories depending on the variables referenced in the so-called range and quantiier predicates. For the three most important classes we enumerate the known query evaluation plans and devise some new o...
