We examined the association between the Catechol-O-methyltransferase (COMT) Val158Met polymorphism and aggressive schizophrenia. The sample included 61 aggressive schizophrenic patients as well as 104 non-aggressive patients from psychiatric hospitals and 415 healthy volunteers in South Korea. In the case-control comparisons, there was no significant(More)
This paper proposes a reliable wildfire monitoring system based on a wireless sensor network (WSN) sparsely deployed in adverse conditions. The physical environment under consideration is characterized by asymmetric, irregular, and unreliable wireless links, inadequate Fresnel zone clearance, and routing problems, to name a few. We use reliable(More)
Rapid advances in wireless sensor networks require routing protocols which can accommodate new types of power source and data of differing priorities. We describe a priority-based geographical routing scheme based on a solar-cell energy model. It exploits an algorithm (APOLLO) that periodically and locally determines the topological knowledge range of each(More)
This paper proposes automatic target detection and tracking system using Active Shape Model (ASM). Existing model based approaches for tracking are either manually initiated or need some form of user interaction to locate the object in images. Also the low light environmental conditions for surveillance systems make the tracking further harder. Hence the(More)
Many large scale sensor networks produce tremendous data, typically as massive spatio-temporal data streams. We present a Low Complexity Sensing framework that, coupled with novel compressive sensing techniques, enables to reduce computational and communication overheads significantly without much compromising the accuracy of sensor readings.
