Fiber-reinforced polymeric composites are used widely due to their unique properties of light weight, stiffness and high strength weight ratio. During processing and servicing, the composite materials undergoes delamination, and petalling. Computational model was constructed for finite element modeling to reflect material purpose under impact load and relevant material properties were taken. In...
در چند سال اخیر استفاده از مواد کامپوزیت جهت تقویت و مقاومسازی سازههای بتن مسلح رشد چشمگیری داشته است. تحقیقات بسیاری در خصوص افزایش ظرفیت باربری محوری، ظرفیت برشی و شکلپذیری ستونهای بتن مسلح دور پیچ شده با الیاف کامپوزیت انجام گرفتهاست که همه این تحقیقات نشان از عملکرد مناسب مواد کامپوزیت در بهبود عملکرد ستونهای بتن مسلح دارد، اما دورپیچ کامپوزیت تاثیر چندانی بر روی افزایش ظرفیت خمشی و ...
This article presents results of an investigation that focuses on assessing bondline strength carbon/epoxy fiber reinforced polymeric (CFRP) precured strips embedded in concrete for near-surface-mounting (NSM) strengthening applications. In this study, experimental evaluation and nonlinear numerical analysis CFRP/concrete interfacial bond behavior are investigated. 15 pull-out tests were perfor...
در این تحقیق، رفتار آزمایشگاهی تیر عمیق بتن مسلح که با ورق پلیمر مسلح شده با الیاف کربنی (CFRP) به دو روش نصب خارجی (EB) و روش نصب در شکاف نزدیک سطح (NSM) مقاومسازی برشی شده، مورد بررسی قرار گرفته است. برای این هدف، 6 تیر به طول 145 سانتی متر، ضخامت 15 سانتی متر و ارتفاع50 سانتی متر ساخته شده و تحت آزمایش قرار گرفتند. آرایش ورق CFRP روی جان همه تیرهای مقاومسازی شده، بصورت قطری و عمود بر خط وا...
An Integral Nested Sliding Mode Control (INSMC) is proposed for n-link robotic manipulators tracking problem by employing Integral Sliding Mode (ISM) and Nested Sliding Mode (NSM) concepts. This controller has the robustness of NSM against matched and no matched perturbations, and the capability of ISM to reduce the sliding functions gains. Application to a two-link planar robot manipulator is ...
BACKGROUND Previously, we investigated the role of the Rift Valley fever virus (RVFV) virulence genes NSs and NSm in mosquitoes and demonstrated that deletion of NSm significantly reduced the infection, dissemination, and transmission rates of RVFV in Aedes aegypti mosquitoes. The specific aim of this study was to further characterize midgut infection and escape barriers of RVFV in Ae. aegypti ...
In this paper, we analyze the Network and System Management (NSM) requirements and NSM data objects for the intrusion detection of power systems; NSM is an IEC 62351-7 standard. We analyze a SYN flood attack and a buffer overflow attack to cause the Denial of Service (DoS) attack described in NSM. After mounting the attack in our attack testbed, we collect a data set, which is based on attribut...
Mesolimbic areas such as nucleus accumbens, amygdala and septal nuclei are known to influence food intake and body weight. However, the reports on gender difference in the neural regulation of obesity and energy homeostasis are incomplete. Therefore, the present study was conducted to assess the effect of lesions of nucleus septal medialis (NSM) and the gender difference of lesion on food intak...
In this study, a new crossover sine model (CSM) n was developed from a trigonometric model [M. E. Fisher, S. Zinn, and P. J. Upton, Phys. Rev. B 59, 14533 (1999)]. The trigonometric model is a parametric formulation model that is used to represent the thermodynamic variables near a critical point. Although there are other crossover models based on this trigonometric model, such as the CSM and t...
Breast cancer is the most common cancer diagnosed in women. Nipple-sparing mastectomy (NSM) offers the opportunity to preserve the breast envelope and the nipple-areolar complex by removing only breast tissue and avoiding multiple surgical procedures for reconstruction. The objective of this article is to review the oncologic and surgical concerns with NSM, along with the appropriate selection ...
