background : chaff cutter, a commonly used fodder cutter machine in rural parts of india is responsible for a significant number of agricultural-related accidents. mostly, these accidents lead to amputation of the upper extremities and the fatal injuries are extremely rare. case report: this article presents a very unusual case of fatal head injury and crush injury to right leg sustained by a f...

Solar energy is a renewable energy. Earth continuously intercepts solar power of about 1.78 x 1011 MW. By using converging devices may be converted into other form Use in agricultural field essential now-a-days. photovoltaic system converts directly electrical cell [3]. Increasing wind velocity improved the generated by panel [6]. The main aim this paper experimental study and testing operated ...

In order to verify the chaff jamming performance, according to the time-frequency distribution and statistical characteristics of chaff echo, this paper presents a modeling and simulation method of chaff echo based on its mechanism of generation, Also it presents a simulation study of chaff echo signal based on LFM signals. The simulation results indicate that the generated chaff echo of this m...

In Modern warfare scenario, thin conducting chaff fibers with very high aspect ratio are used as passive electronic countermeasure. Radar Cross Section (RCS) of chaff cloud is an important parameter deciding its performance as electronic countermeasure. The chaff cloud is a dynamic target as when it is dispensed, it blooms in the atmosphere depending upon the atmospheric conditions and the plat...

Chaff is one of the most widely used and effective expendable electronic attack (EA) devices. It is a form of volumetric radar clutter consisting of multiple metalized radar reflectors known as chaff fibers designed to confuse hostile radar operation. It is dispensed into the atmosphere to deny radar acquisition, generate false targets. To understand the dynamics of chaff cloud, a software has ...

Since enterohemorrhagic Escherichia coli O157, Salmonella, etc., sometimes contaminate animal feces and may cause infectious diseases to humans, it is important to remove pathogenic bacteria from domestic animal waste. For the purpose, we examined the antibacterial activity of chaff vinegar. We found that the chaff vinegar inhibited the growth of pathogenic bacteria immediately in vitro but not...

In this paper, we propose a cross-matching algorithm that can detect stepping-stone intrusion. The theoretical analysis of this algorithm shows that it can completely resist intruder’s time-jittering evasion. The results of the experiments and the simulation show that this algorithm can also resist intruders’ chaff-perturbation with chaff-rate up to 80%. Compared with A. Blum’s approach, which ...
