Universities and other educational organizations are adopting computer-based assessment tools (herein called e-exams) to reach larger and ubiquitous audiences. While this makes examination tests more accessible, it exposes them to unprecedented threats not only from candidates but also from authorities, which organize exams and deliver marks. Thus, e-exams must be checked to detect potential ir...

In this paper, an attempt has been made to predict and evaluate the entrance length in pipe for low Reynolds number flow using evolutionary-optimized Adaptive-Neuro Fuzzy Inference System (ANFIS). For optimization purpose, evolutionary algorithm namely particle swarm optimization (PSO) is adopted. We trained and tested the model using 100 experimental records from computational fluid dynamics (...

The F(2)+CH(3)SCH(3) reaction was studied with crossed molecular beam techniques and high level ab initio calculations. Significant reactivity was observed even at low collision energies, consistent with the negligible barrier height obtained from the ab initio calculations. All experimental findings are consistent with a weakly bound reaction intermediate of F-F-S(CH(3))(2) structure, which po...

INTRODUCTION AND OBJECTIVES Occasionally, implanting a left ventricular pacing electrode for cardiac resynchronization therapy via the coronary sinus may be complicated by the presence of anatomical structures that obstruct the access to the target vein. Our objective was to report on experience using a double-wire technique for implanting left ventricular venous leads gained at the Dr Negrín H...

BACKGROUND The Objective Structured Clinical Evaluation (OSCE) has been considered a reliable method for the evaluation of students' clinical skills in health sciences, but it has been rarely applied in the teaching of physical therapy. OBJECTIVE To assess the use of the OSCE as a tool to evaluate the abilities of undergraduate chest physical therapy students and to verify the internal consis...

Introduction:   Nowadays we are witnessing an exponential application of interventional radiology techniques in various communities as well as Iran. Radiological technique is regarded as  the  2nd  contributing  factor in  increasing  the  amount  of  public  doses  in various societies. So that related radiation protection organization has recommended measuring patient d...

OVER three-hundred and thirty years ago, just when England was about to be rent apart by the Civil War, Thomas Browne, a student of Padua and Montpellier and a Doctor of Medicine of both Leiden and Oxford, wrote Religio Medici. This contributed little to religion, but in the stately prose of a bygone age ranged far and wide with protestations of piety and a gentle irony. One of the best known p...

This paper describes an approach to detect the entrance of building with hopeful that it will be applied for autonomous navigation robot. The entrance is an important component which connects internal and external environments of building. We focus on the method of entrance detection using multiple cues. The information of entrance characteristics such as relative height and position on the bui...

Many DMD-based programmable light sources consist of a white light source and a pair of spectrometers operating in subtractive mode. A DMD between the two spectrometers shapes the delivered spectrum. Since both spectrometers must (1) fit within a small volume, and (2) provide significant spectral resolution, a narrow intermediary slit is required. Another approach is to use a spectrometer desig...
