early warning systems are key components of strategies to reduce risk. this research, by adopting a systematic approach in the management of the risk of desertification and by including previously developed models and systems, offers an integrated efficient structure in terms of early warning for the risk of desertification as a pilot system for semi-arid areas of west golestan province in iran...

To monitor water quality continuously over the entire sewer network is important for efficient management of the system. However, it is practically impossible to implement continuous water quality monitoring of all junctions of a sewer system due to budget constraints. Therefore, water quality monitoring locations must be selected as those points which are the most representative of the dataset...

Foreground  background segmentation is the primary step of most automated video monitoring system aiming at object tracking, event detection or scene interpretation. In uncontrolled environments, with dynamic background and lighting changes, this basic task is very challenging. This work is based on the hypothesis that the combination of LWIR (8-12 m) and colour cameras can significantly impr...

This paper presents a concept, architecture and an FPGA-based prototype of a smart image sensor for video cameras to be integrated into Intelligent Video Surveillance Systems. The system utilizes a distributed cooperative architecture with appropriate level of intelligence at different levels. The sensor performs automated scene analysis and provides immediate response to suspicious events by o...

In this paper, a novel neuro-fuzzy based method combined with a feature selection technique is proposed for online dynamic voltage stability status prediction of power system. This technique uses synchronized phasors measured by phasor measurement units (PMUs) in a wide-area measurement system. In order to minimize the number of neuro-fuzzy inputs, training time and complication of neuro-fuzzy ...

Aims: The use of the electronic health record systems has been developed in the health system, but it is still not known whether empathy is created in the visit of the patient despite this system. Therefore, this study was designed with the purpose of comparing patients’ perceptions about physicians’ empathy after the patient viewed standardized and scripted video vignettes of two physicians on...

Based on the newly developed DaVinci technology, a designing scheme of embedded web video monitoring system is proposed. The scheme combines high-speed and dual-core signal processor (TMS320DM6467) with embedded Linux operating system as the platform to complete the H.264 encoding, transmission and storage of video signal. Building the embedded Web server, user can login into the server and mon...

Video surveillance is a basic mean for fields monitoring, but in uncertain plots for emergency, it is usually impossible to construct a delivery channel for video surveillance. With the wide spreading of 3G network and smart phones equipped with powerful processor and context-aware sensors, it is possible to build a context-aware based mobile surveillance. This work provided a mobile video surv...

In this paper, we describe a video indexing system that automatically searches for a specific person in a news sequence. The proposed approach combines audio and video confidence values extracted from speaker and face recognition analysis. The system also incorporates a shot selection module that seeks for anchors, where the person on the scene will be likely speaking. The system has been exten...
