This study set out to explore the impact of three levels of task planning on the accuracy of task-based oral performance with narrative task types among sixty Iranian sophomores majoring in Teaching English as a Foreign Language (TEFL) at Islamic Azad University – Tabriz Branch. It was hypothesized that simultaneous pre-task/on-line planning would lead to more accurate performance. To test the ...

Purpose: We present a method that allows one to generate data from nasopharyngoscopy videos into a form suitable for use in radiation treatment planning, as well as for review of the data itself as a 3D object. Methods and Materials: The accurate transfer of data from endoscopic video frames to the planning CT requires an explicit endoscopic video/CT registration. Our approach to accomplishing ...

background: in treating patients with radiation, the degree of accuracy for the delivery of tumor dose is recommended to be within ± 5% by icru in report 24. the experimental studies have shown that the presence of low-density inhomogeneity in areas such as the lung can lead to a greater than 30% change in the water dose data. therefore, inhomogeneity corrections should be used in treatment pla...

While model-based reinforcement learning is often studied under the assumption that a fully accurate model is contained within the model class, this is rarely true in practice. When the model class may be fundamentally limited, it can be difficult to obtain theoretical guarantees. Under some conditions the DAgger algorithm promises a policy nearly as good as the plan obtained from the most accu...

We propose that spatial inferences made during planning and executing a route influence the learning of relative locations through wayfinding. In Experiment 1, separate and combined route plans were compared. The results suggest that inferring multiple directions during the initial stage of planning leads to more accurate representations of relative locations than planning a single route. In Ex...

Positioning service is one of Wireless Sensor Networks’ (WSNs) fundamental services. The accurate position of the sensor nodes plays a vital role in many applications of WSNs. In this paper, a 3D positioning algorithm is being proposed, using mobile anchor node to assist sensor nodes in order to estimate their positions in a 3D geospatial environment. However, mobile anchor node’s 3D path optim...

Endometriosis with extensive deep affectation needs a targeted MR study for an accurate diagnosis and treatment planning. The reported patient had affectation of the three compartments, with solid invasive masses, predominantly fibrous. Since laparoscopy provides limited information on the sub peritoneal extent and presence of endometriotic lesions in areas hidden by adhesions, the non-invasive...

Because of today's strong competition, most manufacturing organizations continually try to increase their profits and reduce their costs. Accurate sales forecasting is certainly an inexpensive way to meet these goals because it leads to improved customer service, reduced lost sales and product returns, and more efficient production planning (Doganis et al., 2006). Forecasting future demand is c...

The technical development described herein was undertaken to create a tumor ablation treatment system that consists of a software component and a robotic hardware component. First, the software treatment planning system enables applicator placement planning before tumor ablation. For example, it allows creation of overlapping ablations with the goal of treating larger tumors. Second, the roboti...

OBJECTIVE Treatment of acetabular fractures remains one of the most challenging tasks that orthopaedic surgeons face. An accurate assessment of the injuries and preoperative planning are essential for an excellent reduction. The purpose of this study was to evaluate the feasibility, accuracy and effectiveness of performing 3D printing technology and computer-assisted virtual surgical procedures...
