در این پایان نامه یک مفهوم جدید مربوط به نظریه قاب ها معرفی شده است؛ مفهوم جفت قابها. با بررسی برخی ویژگی های آن، نشان داده شده است که که جفت قاب ها تعمیمی از قابهای معمولی هستند. چند رده از جفت قابها نیز معرفی شده اند، مانند -جفت قاب ها و جفت قاب های نردیک به همانی. متناظر با هر جفت قاب نزدیک به همانی، یک دنباله از جفت قاب های نزدیک به همانی یافت می گردد که عملگر قاب آنها به عملگر همانی میل می...
In this paper, we prove that it is always possible to define a realization of the Laplacian $$\Delta _{\kappa ,\theta }$$ on $$L^2(\Omega )$$ subject nonlocal Robin boundary conditions with general jump measures arbitrary open subsets $${\mathbb {R}}^N$$ . This made by using capacity approach an admissible pair $$(\kappa allows associated form $${\mathcal {E}}_{\kappa be closable. The generates...
هدف از پژوهش حاضر بررسی تاثیر 8 هفته طرح درسی طناورز بر برخی از شاخص های ترکیب بدنی و آمادگی جسمانی دانش آموزان دختر کلاس چهارم ابتدایی بود. جامعه آماری در این پژوهش شامل کلیه دانش آموزان دختر کلاس چهارم ابتدایی( 10 تا 11 سال ) شهر شیراز بود. آزمودنی های تحقیق 48 دانش آموز بودند که به صورت نمونه در دسترس انتخاب شدند و به صورت تصادفی در دو گروه شامل 28 نفر در گروه آزمایش و 18 نفر در گروه کنترل ق...
Purpose: Various kinematics and kinetics methods have been proposed for the assessment of jumping ability as a critical skill in professional volleyball players, but little is known about the accuracy and differences between these methods. Therefore, the objective of the current study was to answer the question “Is there any difference between the results of various kinetic methods in the asses...
In this study accuracy of the ANFIS and ANFIS-PSO models to estimate hydraulic jump characteristics including sequence depth ratio, the jump length, the roller length ratio, and relative energy loss was evaluated in stilling basin versus laboratory results. The mentioned characteristics were measured in the stilling basin with a rectangular cross-section with four different adverse slopes, four...
in this thesis we will present three topics. we define approximate fixed points in fuzzy normed spaces. also we obtain some necessary and sufficient conditions on the existence of? -fixed points for ? > 0. at the continue some results about approximate fixed points for a class of non-expansive maps on g-metric spaces are obtained and we define approximate fixed points in partial metric spa...
The tooth surface 3d modification technology is the most effective method to realize reduction of vibration and noise gear system (GS) by comprehensively considering profile axial modification. Moreover, nonlinear factors such as backlash bearing clearance will make motion GS have complex variability. Therefore, we combine with contact performance dynamic characteristics optimize meshing herrin...
There is a substantial evidence that plyometric training significantly increases muscular strength and vertical jump. Due to the vigorous nature of this type of training, however, there is a risk of incurring musculoskeletal injuries. Therefore, conducting plyometric exercise programs in an aquatic environment might lead to significant improvements in vertical jump with possibly a lower risk of...
One of the most important problems in the design of a stilling basin is determination of the exact location of the hydraulic jump or stabilization of the hydraulic jump. In the present study, the effects of different forms of end sills on hydraulic jump characteristics were studied. The experiments were carried out for three different forms of end sills, rectangular, square and stepped, with th...
