In automotive industry fixtures have a direct effect on product manufacturing quality, productivity and cost, as a result fixtures, particularly welding fixture, play a crucial role in the auto industry. The fixture is a special tool for holding a work piece in proper position during manufacturing operation, so in the phase of the fixture design process positioning pins and surfaces are used to...

The paper presents an indoor navigation solution by combining physical motion recognition with wireless positioning. Twenty-seven simple features are extracted from the built-in accelerometers and magnetometers in a smartphone. Eight common motion states used during indoor navigation are detected by a Least Square-Support Vector Machines (LS-SVM) classification algorithm, e.g., static, standing...

While commercial solutions for precise indoor positioning exist, they are costly and require installation of additional infrastructure, which limits opportunities for widespread adoption. Inspired by robotics techniques of Simultaneous Localization and Mapping (SLAM) and computer vision approaches using structured light patterns, we propose a self-contained solution to precise indoor positionin...

Several studies have considered reducing instruction cache misses and branch penalty stall cycles by means of various forms of code placement. Most proposed approaches rearrange procedures or basic blocks in order to speed up execution on sequential architectures with branch prediction. Moreover, most works focus mainly on instruction cache performance and disregard execution cycles. To the bes...

With the rapid advancements in positioning technologies such as the Global Positioning System (GPS) and wireless communications, the tracking of continuously moving objects has become more convenient. However, this development poses new challenges to database technology since maintaining up-to-date information regarding the location of moving objects incurs an enormous amount of updates. Existi...

A new discrete event controller synthesis methodology for the successful convergence of assembly tasks is presented. Discrete event control has been shown to be a very eeective strategy to incorporate both the continuous and discrete natures of an assembly task. A discrete event controller synthesis methodology for force-controlled systems is highly desirable because force control is naturally ...

Global Positioning System (GPS) is proven to be an accurate positioning sensor. However, there are several sources of errors such as ionosphere and troposphere effects, satellite time errors, errors of orbit data, receivers errors, and errors resulting from multi-path effect which reduce the accuracy of low-cost GPS receivers. These sources of errors also limit the use of single-frequency GPS r...

Introduction: The accuracy of patient positioning plays an important role for radiotherapy tasks. Short and automated Quality Assurance (QA) programs are becoming one of the challenging tasks in Radiotherapy. The current study, investigates the accuracy of treatment couch positioning with four degrees of freedom (4DoF) using a fast and accurate method based on an image acquired...

Acute respiratory distress syndrome (ARDS) is an inflammatory process in the lungs that results hypoxemia and decreased lung compliance. Invasive mechanical ventilation prone positioning have proven benefits management of patients with severe ARDS. Post-extubation rehabilitation programs are equally important for recovery these patients. We reporting case a 30-year-old male ARDS where protectiv...

A quantum sensor network with multipartite entanglement offers a sensitivity advantage in optical phase estimation over the classical scheme. To tackle richer sensing problems, we construct distributed four nodes via partite entanglements, unveil of higher order derivative radio-frequency signal phase, and unlock potential target ranging space positioning. Taking phased-array radar as an exampl...
