The aim of the work was to investigate numerical simulations correlation with experimental behaviour steel ball high velocity impact onto a 2 × twill woven carbon composite laminate. set up consisted pressurised gas-gun able shot projectiles two different plate layup configurations plates made same material fabric. Subsequently, experiments were replicated using LSDYNA explicit finite element a...
According to the importance and the increasing trend of idiosyncratic volatility in recent years, the study of factors affecting idiosyncratic volatility is one of the important issues in financial markets. So, the purpose of this study is to investigate the relationship between lifecycle and idiosyncratic volatility with emphasis on fundamental and information uncertainty. In this regard, 152 ...
قطعه کاری چمن یکی از روش های مهم احداث و ترمیم چمن می باشد. در تحقیق حاضر یک دستگاه چمن بر که توسط تراکتور دو چرخ کشیده می شود، طراحی، ساخته و ارزیابی گردید. قسمت های مختلف دستگاه چمن بر شامل تیغه زیربر، تیغه های کناربر، ساقه ها، قاب و چرخ حامل می باشد. بعد از به دست آوردن نیروهای وارد بر تیغه، قاب دستگاه توسط نرم افزار cosmosworks تحلیل تنش شد. به منظور طراحی اجزاء مختلف دستگاه ، برخی خصوصیات ...
leaders failure in correct evaluation of feelings and emotions of employees, may act as a barrier in achieving organizational goals. therefore it is important to pay attention to job and contextual performance arising from positive behaviors such as cooperation and effort of employees. moreover, employees’ training is usually focused on recognition teaching, and less on emotional- social aspect...
Effect of addition of filler material to the natural fiber composite was experimentally investigated. Composites are manufactured by the conventional hand-layup method. All composites are made with a fixed banana fiber with 15% weight fraction addition of different weight fraction of (0, 3, 5, 7.5%) groundnut shell ash is added to the composite. Tensile, hardness, impact and compressive strengt...
OBJECTIVE Human papillomavirus (HPV) testing has been proposed for inclusion in the UK cervical screening programme. While testing may bring some benefits to the screening programme, testing positive for HPV, a sexually transmitted virus, may have adverse social and psychological consequences for women. The aim of this study was to examine the social and psychological impact of HPV testing in t...
Change impact analysis is an imperative activity for the maintenance of software. It determines the set of modules that are changed and modules that are affected by the change(s). It helps in regression testing because only those modules that are either changed or affected by the suggested change(s) are retested. Change impact analysis is a complex activity as it is very difficult to predict th...
