Automatic road extraction from aerial images can be very helpful in traffic control and vehicle guidance systems. Most of the road detection approaches are based on image segmentation algorithms. Color-based segmentation is very sensitive to light changes and consequently the change of weather condition affects the recognition rate of road detection systems. In order to reduce the light change ...

Entanglement is one of the most puzzling features of quantum theory and of great importance for the new field of quantum information. The determination whether a given state is entangled or not is one of the most challenging open problems of the field. Here we report on the experimental demonstration of measurement-device-independent (MDI) entanglement detection using witness method for general...

Most of these claims are supported by only anecdotal evidence. This is unfortunate because it is often extremely difficult to rule out non-psychic explanations. For example, Hoebens (1985) has described how some psychics have made several (often conflicting) predictions relating to an unsolved crime. Once the crime was solved the incorrect predictions were forgotten whilst the correct ones were...

water contamination due to the wide variety of pesticides used in agriculture is a global environmental pollution problem. in order to reach at sub-î¼gl-1 levels of detection, an efficient extraction technique is required. a simple, fast and economical method, dispersive liquid-liquid micro extraction (dllme), followed by gas chromatography-mass spectrometry was assessed for determining endosul...

The indirect evidence for the existence of nonbaryonic cold dark matter is significant and varied. However, it is critical to demonstrate directly the existence of a specific species of nonbaryonic cold dark matter by observing it in some direct way and measuring its properties. In this chapter, I discuss various techniques used to search for WIMP dark matter, which fall under the categories of...

We report on the first experimental realization of the entanglement witness for polarization entangled photons. It represents a recently discovered significant quantum information protocol which is based on few local measurements. The present demonstration has been applied to the so-called Werner states, a family of ”mixed” quantum states that include both entangled and non entangled states. Th...

Acute intestinal &hernia is associated with a mortality of more than 80% [2, 3, 14, 181. Periods of &hernia greater than 6 to 12 hr often commit the surgeon to an extensive resection of gangrenous bowel from which few of these critically ill patients can recover [ 141. Delay in diagnosis is recognized as the major factor contributing to the high morbidity associated with this condition [3]. Cle...

This report documents the work conducted for PATH Task Order 5200 – the evaluation of sensor technologies for pedestrian detection. A survey of recent and available sensor products were selected and evaluated to assess their applicability for vehicle-based solutions. The performance characteristics and limitations of various products and technological approaches were investigated. Subsequently,...

most of the contour detection methods suffers from some drawbacks such as noise, occlusion of objects, shifting, scaling and rotation of objects in image which they suppress the recognition accuracy. to solve the problem, this paper utilizes zernike moment (zm) and pseudo zernike moment (pzm) to extract object contour features in all situations such as rotation, scaling and shifting of object i...

The number and impact of attack over the Internet have been continuously increasing in the last years, pushing the focus of many research activities into the development of effective techniques to promptly detect and identify anomalies in the network traffic. In this paper, we propose a performance comparison between two different histogram based anomaly detection methods, which use either the ...
