<p> Fatigue tests were conducted on base line CT specimen under single overload ratios of 1.5 and 1.75. Numerical analyses were performed on 2D incorporating the stress intensity factor and the J-integral as driving force. Figures of velocity variations and force variations of projectile, damaged area, different mechanisms of fracture were reported as results and commented upon. Moreover, peak wind velocity and duration of intense winds are important factors that have important effects on the destruction pattern of tall structures. To have a more realistic simulation a setup were designed and developed to measure the sensors noise performance as well as the actuators’ dynamics. This paper presents the inverted PID control of a quadrotor based on the experimentally measured sensors and actuators’ specifications. First, the stress field of the cylinder under thermal and mechanical loads is extracted based on semi couple thermo-elastic equations. In this study for more reasonable comparison of thermal recovery the inlet and outlet temperatures of heat source heat carrier fluid and its mass flow rate are considered to be constant. Among them, Gagge’s model because of its ability in estimating body physiological responses and thermal sensation in transient conditions has turned to one of the most used thermal comfort models.</p>

<p> In continue, the effect of the pore size and the number of the holes on the relative density of the foams has studied. In this article, a new method has presented for modeling of closed-cell foams and a program has written in macro environment of CATIA software in Visual Basic language which made the modeling of metallic foams with controllable pore size and density possible. The main characteristic of the foams is the existence of pores in them which are distributed randomly. Then, reference trajectories for tracking problem are produced. To overcome this shortcoming, an experiment should be performed in different steps and relations between these steps of the experiment are determined by selection of some specific points as reference points. In this paper, a new index for selection of reference points is introduced which is more efficient in the noisy environments. Obtained results from numerical and experimental cases show that the proposed index is more capable in reference point selection and calculation of the modal parameters of the structures comparing to the results of correlation method.</p>

<p> Moreover, the results show that the area near the root is strongly influenced by rotational effects. Next, the effects of pitch angle and the angle between the flow direction and rotation vector on the Coriolis terms were applied using geometry factor definition and Blade Element Momentum (BEM) theory. Then, the integral parameters and effective geometry factors on separation positions and stall structure were investigated for a rotating blade. At first, boundary layer and three-dimensional momentum integral equations were obtained for incompressible flow considering rotation effects. To improve resistance of structures which face tornado, the flow field and factors which affect damage patterns of tornado need to be investigated. Hence, stepped tip gap extends the stable operating range of compressor and delays the occurrence of stall phenomenon. Because of the importance of these materials in engineering and other applications, there has been given importance to modeling of them. کمپرسور باد بی صدا یا سایلنت به کمپرسور اطلاق می شود که نویز تولیدی آن هنگام کارکرد در دسی بل پایین تری باشد . همچنین اثر اضافه شدن نویز در سیگنال پاسخ بررسی شده است. تمام قطعات یدکی این شرکت کارآمد و قابل تعویض با قطعات کمپرسورهای خارجی هستند و با اعتماد کامل به بهتر شدن عملکرد دستگاه ها می توانید از آنها استفاده کنید.</p>

<p> مقایسهی خواص فومهای مدل شده با استفاده از الگوریتم ارائه شده و فومهای واقعی مطابقت خوبی را نشان داده است. بنابراین در این مقاله شاخص جدیدی برای انتخاب نقاط مرجع ارائه شده است که در محیط نویزی عملکرد مناسب تری دارد. بنابراین درز نوک پلّهای، سبب افزایش محدوده عملکرد پایدار کمپرسور شده و وقوع پدیده استال را بهتأخیر میاندازد. نتایج نشان می دهد که با توجه به مطابقت شیب دمایی در چگالنده و تبخیرکننده در استفاده از سیال مخلوط دوجزیی، در مقایسه با سیالکاری خالص افزایش راندمان حرارتی و اگزرژی حدود 9% در پیکربندی ساده و 14% در سیکل با مبدل حرارتی داخلی، قابل دسترس است. مکش گریز از مرکز حاصل از چرخش، به خصوص در نواحی نزدیک به ریشه، موجب کاهش ضخامت لایه مرزی و به تعویق افتادن جدایش و همچنین، افزایش ضرایب آیرودینامیکی پره میشوند. در این خصوص شرکن فرافن هوا با نرم افزار اقدام به محاسه سایز مناسب می نماید . به منظور غلبه بر این مشکل، آزمایش باید در چندین مرحله انجام شده و ارتباط بین مراحل آزمایش با انتخاب نقاطی به عنوان نقاط مرجع برقرار شود.</p>
