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.

Wanning Xiaohai is the largest lagoon in Hainan Province. In recent years, body of water has been polluted due to untreated discharge domestic sewage and aquaculture tailwater directly into Xiaohai. order improve quality relieve pressure on environment, it was decided restore tidal inlet this study, module finite volume ocean model applied simulate change pollution concentration using Eulerian ...

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...

In this paper, an efficient depth-aware image enhancement system is presented. The depth information and well-known depth-cue relative perception are used to enhance 2D still images or videos. Image enhancement has been developed for decades in a lot of fields. However, conventional approaches deal with images in the 2D(x-y) projective plane. The information of z-axis is not used. In this work,...

A single two dimensional (2D) image does not contain depth information. An infinite number of points in the three dimensional (3D) space are projected to the same point in the image plane. But a single 2D image has some monocular depth cues, by which we can make a hypothesis of depth variation in the image to generate a depth map. This paper proposes an interactive method of depth map generatio...

The traditional Three-dimensional (3D) model for stability analysis of a large underground cavern group only includes the main powerhouse, transformer chamber, tailrace surge tank, electrical wire hall, and part diversion tunnel tailwater tunnel. Other caverns excavation are not taken into consideration, which is inconsistent with actual project. In this study, 3D Finite Element Method (FEM) mo...

Constructed wetlands, as natural sewage treatment ecosystems, have been widely used in the fields of rural domestic and plant tailwater treatment. However, synchronous removal phosphorus most constructed wetlands is not ideal. This study aimed to prepare thermally modified sepiolites with high adsorption capacities design a wetland based on them. Thermal modification was adopted enhance capacit...

Indigenous mixed populations of anaerobic microorganisms from an irrigation tailwater drain and submerged agricultural chemical waste pit readily biodegraded the major isomer of endosulfan (endosulfan I). Endosulfan I was biodegraded to endosulfan diol, a low toxicity degradation product, in the presence of organic carbon sources under anaerobic, methanogenic conditions. While there was extensi...

We evaluated the movement of adult brown trout Salmo trutta and rainbow trout Oncorhynchus mykiss in relation to a catch-andrelease area in the White River downstream from Beaver Dam, Arkansas. Nine fish of each species were implanted with radio transmitters and monitored from July 1996 to July 1997. The 1.5km river length of a catch-and-release area (closed to angler harvest) was greater than ...
