چکیده- خستگی عبارت است از پدیده ی شکست بر اثر تکرار بار، که تنش ایجاد شده توسط این بار ممکن است حتی به مراتب کوچک تر از مقاومت نهایی مصالح باشد .ترکهای ناشی از خستگی، در مقاطع آسفالتی، با توجه به مکان پیدایش و نحوه ی گسترش آنها دو دسته است .دستهی اول ترک هایی است که در بخش پایینی مقطع آسفالتی پدید می آیند و سپس با تکرار بار بهسمت بالا گسترش مییابند. پیدایش این نوع ترک ها در مقاطع آسفالتی با ضخا...
We report three cases of asymptomatic celiac disease identified in children with Down syndrome after being screened at around twenty-four months of age. These cases raise the question as to what age is screening for celiac disease indicated in a child with Down syndrome and no symptoms.
Management of natural resources in coastal ecosystems is a complex process that is made more challenging by the need for stakeholders to confront the prospect of sea level rise and a host of other environmental stressors. This situation is especially true for coastal military installations, where resource managers need to balance conflicting objectives of environmental conservation against mili...
A public housing reorganizing plan is needed to prepare for future population decline, but it difficult manually find a financially reasonable combination that allows tenants relocate. Therefore, an algorithm search combinations could be subject multiple estates was developed using depth-first search. This led of all blocks the Hyuga Municipal Housing, and narrowed down with lowest financial bu...
We investigate the existence of a true invariant manifold given an approximately invariant manifold for an infinite-dimensional dynamical system. We prove that if the given manifold is approximately invariant and approximately normally hyperbolic, then the dynamical system has a true invariant manifold nearby. We apply this result to reveal the global dynamics of boundary spike states for the g...
Because a biomass gasification station includes various hazard factors, hazard assessment is needed and significant. In this article, the cloud model (CM) is employed to improve set pair analysis (SPA), and a novel hazard assessment method for a biomass gasification station is proposed based on the cloud model-set pair analysis (CM-SPA). In this method, cloud weight is proposed to be the weight...
The gradient flow approach to the Cahn-Hilliard and phase field models is developed, and some basic mathematical properties of the models, especially phase separation phenomena, are reviewed.
This study deals with prioritization of sustainable supply chin measurement indicators which are calculated by using Chang’s extent method of Fuzzy AHP. Within the model of Fuzzy AHP, main attributes, sub attributes and indicators are defined. The weights of them are calculated from the answers of questionnaire, which is formed for pair-wise comparison of attributes and indicators. The results ...
Abstract. In this paper, we study the global existence of classical solutions for the Cahn-Hilliard equation with terms of lower order and non-constant mobility. Based on the Schauder type estimates, under some assumptions on the mobility and terms of lower order, we establish the global existence of classical solutions.
