The objective of this paper is to study the impact of depth perception and movement freedom on learning surgical tasks by novice subjects using new laparoscopic technology.
With the recent development of new three-dimensional (3D) multimedia services such as 3D television or free viewpoint television, a new 3D video format, called multiview video+ depth (MVD) is currently being investigated. MVD allows synthesizing as many views as required at the receiver side, thus providing smooth scene transitions and the ability to experience a new 3D perspective with each di...
Cerebral currents responsible for the extra-cranially recorded magnetoencephalography (MEG) data can be estimated by applying a suitable source model. A popular choice is the distributed minimum-norm estimate (MNE) which minimizes the l2-norm of the estimated current. Under the l2-norm constraint, the current estimate is related to the measurements by a linear inverse operator. However, the MNE...
هدف:بررسی نتایج عمل تخلیه چشم ((evisceration و کارگذاری implant در بیماران مراجعه کننده به کلینیک مرکزی شهر در سالهای 1388و 1389 روش مطالعه:این مطالعه که از نوع توصیفی مقطعی بوده در 22 بیمار مراجعه کننده به کلینیک مرکزی شهر که تحت عمل evisceration با روش implant گذاری نوین قرار گرفته اند انجام شده است. بیماران بعد از ثبت اطلاعات دموگرافیک و سوابق چشم پزشکی و اطمینان از عدم دید کامل آنها(nlp) ...
One of the usual ways to dissipate excess energy in the dam's downstream is hydraulic jump. Hydraulic jump is a rapidly varied flow, in which the flow conditions change from supercritical to sub-critical with a large amount of energy loss. In this research, a combination of two water jets in the form of overflow dam and underflow through a slot on the body of an ogee dam with the USBR standard ...
The purpose of this study was to evaluate two perforated sills in the stilling basin and their impact on characteristics of the hydraulic jump, such as the length of the roller of hydraulic jump, decrease in the secondary depth of the hydraulic jump, and the required tailwater depth. Also, the optimal distance of two perforated sills from the beginning of the stilling basin with a fixed height ...
Climate change is one of the most important challenges in sustainable development that has negative effects on the ecosystems, land and water. The main cause of this phenomenon, increasing the concentration of CO2 in the atmosphere. The main method for reducing at CO2 atmosphere is increasing global carbon storage in soils, in other hand 75% total carbon stock on land has stored in soils. The s...
In the present study, effect of current, welding speed and preheat temperature during FB-TIG welding of AA5083 aluminum alloy was studied. Using the Taguchi method, 9 different tests were designed to investigate the effect of welding parameters on the penetration depth. Consistent with predictions, increasing the current and preheat temperature, and reducing the welding speed led to an increase...
Monitored 3-Dimensional (3D) video experience can be utilized as “feedback information” to fine tune the service parameters for providing a better service to the demanding 3D service customers. The 3D video experience which includes both video quality and depth perception is influenced by several contextual and content related factors (e.g., ambient illumination condition, content characteristi...
The use of wind energy is one of the methods of reducing energy consumption. In a moderate and humid climate, where humidity and precipitation are the most prominent features, creating air conditioning is essential for the residents. Balconies, in addition to the effect on the exterior appearance of the building, create functional spaces in the building that direct and manage the air flow. In t...
