The runaway breakdown – extensive atmospheric shower discharge (RB EAS) excited in thunderstorm atmosphere by high energy cosmic ray particles (εp > 10 − 10 eV) generate very powerful radio pulse. The RB EAS theory is compared with observations of radio pulses. An agreement between the theory and experiment is established. The existence of nowaday satellite and ground based systems which obtain...

In video-surveillance, person reidentification is the task of recognising whether an individual has already been observed over a network of cameras. Typically, this is achieved by exploiting the clothing appearance, as classical biometric traits like the face are impractical in real-world video surveillance scenarios. Clothing appearance is represented by means of low-level local and/or global ...

Abstract— Human body tracking has a wide spectrum of applications. Examples include video surveillance, motion and activity capture for medical analysis, just to name a few. In this paper, a human skeleton model is proposed for human body tracking in video surveillance system. The skeleton model is based on 8 important body points namely; head, neck, shoulder, pelvis, knees and, ankles. Basical...

To achieve poliomyelitis eradication, the World Health Organization recommends that countries conduct surveillance for cases of acute flaccid paralysis (AFP). Acute flaccid paralysis (AFP) is defined as a sudden onset of paralysis/weakness in any part of the body of a child less than 15 years of age. This syndromic reporting strategy, of investigating all AFP cases rather than just “suspected p...

we aimed to evaluate the timeliness of reporting of malaria surveillance system and understanding the existing problems.the timeliness of malaria surveillance system of iran was evaluated in four provinces of iran including sistan & baluchistan, hormozgan, kerman (as provinces with local malaria transmission) and khuzestan (without local malaria transmission). in this descriptive-analytic cross...

background: iodine deficiency disorders (idd) have been recognized as a major public health problem worldwide. consequences of idd include goiter, hypothyroidism, and intellectual disability followed by retarded growth and development of the brain. this report aimed to determine the state of idd in fars province, south of iran. methods: in this study, we gathered data from all scientific papers...

Standards for routine surveillance of nosocomial infections have been a fixture in U.S. hospitals since the role of surveillance in reducing rates of infection among hospitalized patients was demonstrated in the Study on the Efficacy of Nosocomial Infection Control (SENIC) project.1 Similar standards for infection control surveillance have been adopted in other developed countries.2 Unfortunate...

background: complete and fast diagnosis, registry and treatment programs are the main effective strategies for controlling infectious diseases. in addition, an organized and extended infectious disease surveillance system is crucial in designing and monitoring communicable diseases control programs. the quality of the surveillance system can be evaluated by several indices such as timeliness, c...
