این پروژه مسائل زیر را مورد بررسی قرار می دهد: بخش اول به بیان کلیات اختصاص دارد. دراین بخش ابتدا تاریخچه مختصری از سرگذشت موشک بیان شده و درباره دلایل مطرح شدن آن در صنعت نظامی امروز بحث می شود و پس از آن، آشنایی مختصری با کل سیستم موجود، حاصل می گردد. دنباله این بخش ، به ذکر مقدمه ای درباره seeker ها اختصاص یافته است . از آنجاییکه وظیفه seeker دریافت سیگنال و استخراج سیگنال خطای مربوط به انحر...
Seekers of information in libraries either go through a librarian intermediary or they help themselves. When they go through librarians they must develop their questions through four levels of need, referred to here as the visceral, conscious, formalized, and compromised needs. In his pre-search interview with an information-seeker the reference librarian attempts to help him arrive at an under...
In this paper we describe an experiment aimed at determining the most effective and natural orientation of a virtual guide that gives route directions in a 3D virtual environment. We hypothesized that, due to the presence of mirrored gestures, having the route provider directly face the route seeker would result in a less effective and less natural route description than having the route provid...
The literature on help-giving behavior identifies individual-level factors that affect a help-giver’s decision to help another individual. Studying a context in which work was highly interdependent and helping was pervasive, however, we propose that this emphasis on the initial point of consent is incomplete. Instead, we find that workplace help-seeking and help-giving can be intertwined behavi...
With increasing threat from different countries, India has to develop a strong defensive barrier against them. The emerging technology in war ammunition makes us one of the well armed countries in the world. One of the most used weapons is missiles, which were extensively developed under the guidance of Dr.APJ Abdul Kalam, the architect of IGMDP (Integrated Missile Development Program). Whateve...
Help-seeking before and after episodes of self-harm: a descriptive study in school pupils in England
BACKGROUND Deliberate self-harm in young people is a cause for concern in many countries. The vast majority of episodes of self-harm do not result in presentation to hospital and relatively little is known about to whom or where adolescents who harm themselves go for help. METHODS This school-based survey of 5,293 15-16 year olds in the United Kingdom investigated sources of help and barriers...
In this literature, a data pre-processing circuit designs and analyses for an infrared image seeker of a subsonic cruise missile are proposed. The flight speed of the missile is 250m/s. Therefore, automatic contrast control and automatic brightness control are usually needed to keep wanted contrast and brightness for best image properties in target recognition and tracking; especially for the m...
Abstract Disturbance rejection rate is an important performance index of the seeker,the disturbance affects extraction accuracy line-of-sight angular velocity output by seeker,and introduce additional parasitic loop in guidance loop,this stability system and reduces missile system. This paper analyzes principle roll-pitch model seeker caused scale deviation between detector, frame angle sensor ...
One of the important parts of the infrared seeker is the counter countermeasure part. Seeking in a field of view with the existence of jammers is not simple and needs effective algorithms. In this paper, several methods of the detection in a crossed array trachers (CAT) seeker will be designed, simulated and evaluated. These methods depend on detecting the appearance of the flare using analzing...
