An infrared based intelligent Traffic System

Abstract: An efficient traffic system is needed for safety of lives, property, time and economy. Here we present a design and implementation of low cost, low power consummated and more reliable an Infrared based intelligent Traffic System. The system is a wireless network based which contains infrared transmitter with a unique identification number and infrared receiver. The system can response rapidly with the violation of traffic rules and shows the result as a tracked ID of the violated vehicle on the LCD (Liquid Crystal Display). This system describes a highly accurate Traffic system using infrared communication. This system achieves high accuracy and more efficiency at Four Way Terminals. This system can be applied in case of both Road divider and Four Way Terminals.

Design and Implementation of IoT Based Perspicacious Egg Incubator System

Abstract: An intellective Incubator is designed to reduce eccentric chicks and to reduce the peril of damage eggs caused by the skeptical environment. The industrial raising of homestead creatures inside under states of cosmically limited versatility is regularly kenned as processing plant cultivating. It is done as a segment of industrial agribusiness which is a lot of strategies that change as laws and innovation change are kenned as industrial agriculture which is intended to induce the most elevated yield at the least cost, using economies of scale, current hardware, present-day prescription, and ecumenical exchange for financing, buys, and deals. The egg incubator is one of the innovations that give opportunity particularly to who need to be an incredible farmer. It is a standout amongst the most comfortable and most speedy ways that can make an item. This innovation will update the egg incubator that has as of now in the market today. This system will naturally control the temperature and sultriness of the incubator for various sorts of the egg. Egg incubator can surmount the creature occupation to brood an egg until incubating.

In vivo analgesic, antipyretic and anti-inflammatory potential of leaf extracts and fractions of Eria javanica.

Abstract: Background The objective of the study was to evaluate the antinociceptive, antipyretic and anti-inflammatory activities of ethanolic extract, methanolic extract and n-hexane and chloroform-soluble fractions of methanolic extract of Eria javanica leaves in animal model (rat and mice). Methods The anti-nociceptive potentials of the extracts were studied using the acetic acid-induced writhing test in mice and the antipyretic activity was investigated using yeast-induced pyrexia in rats. Anti-inflammatory activity test was done on rats at a dose by using carrageenan-induced paw edema test. Results In acetic acid-induced writhing inhibition study in Swiss albino mice, the crude methanolic extract at 200 mg/kg and 400 mg/kg doses and the n-hexane soluble fraction of crude methanolic extract at 400 mg/kg showed statistically significant activity with 53.21 % (p<0.001), 50.36 % (p<0.001) and 67.86 % (p<0.001) inhibition respectively compared to control. The crude ethanolic extract showed statistically significant antipyretic activity from 1 hours and onwards after administration at doses of 200 mg/kg body weight (p<0.005 at 1st hour and p<0.001 at 2nd, 3rd and 4th hour respectively) and 400 mg/kg body weight (p<0.05 at 1st hour and p<0.001 at 2nd, 3rd and 4th hour respectively). The crude methanolic extract showed statistically significant antipyretic activity from 2 hours and onwards at 400 mg/kg body weight (p<0.05 at 2nd hour and p<0.001 at 3rd and 4th hour respectively) and 200 mg/kg body weight dose showed statistically significant antipyretic activity from 3 hours and onward(p<0.001) in Brewer's yeast-induced pyrexia test in albino Wister rats. In carrageenan-induced rat's paw edema test, crude methanolic extract showed statistically significant anti-inflammatory activity from 2nd hour and onwards. The chloroform-soluble fraction of methanolic extract also showed significant activity from 1st hour onwards. Conclusions This study thereby indicates that leaves of E. javanica possess peripheral analgesic, antipyretic and anti-inflammatory activities and therefore a suitable candidate for further study.

An implementation of a lightweight end-to-end secured communication system for patient monitoring system

Abstract: Securing wireless body area network (WBAN), which is often used for collecting precious patient's data, is an inevitable challenge in a modern patient monitoring system (PMS). In general, a PMS consists of several network segments, starting from a WBAN to the user's access network via a server where the patients' data is stored. Apart from the communication links between the WBAN gateway and the server, and between the server and the user's device, the wireless link between the body sensors and the gateway remains susceptible to threat by eavesdropper or malicious users. Moreover, the sensor nodes are often battery powered and thus cannot be overloaded with highly computational algorithms and protocols. In this context, we develop and implement an end-to- end secure PMS by emphasizing on securing sensor to gateway wireless link with a lightweight encryption protocol that will consume minimal energy. In addition, we use MQ telemetry transport (MQTT) as a transport protocol rather than hypertext transport protocol (HTTP) for its simplicity and lightweight features. The encrypted sensor data thus transported and stored in the server from where an authentic user access the data and decrypt it.
