The MANETs form their network without any infrastructure facilities, whenever needed. Military activities frequently need the quick and secure transfer of large quantities of data. The radio spectrum has been used by the military up until now for good communication but might have a chance to impact security problems. The security of data transfer is a major issue given the natural component of wireless networks in real-time situations. The main challenge is confirming trust across MANET nodes, as well as dealing with bandwidth, energy, and changing topology. By degrading the trust level between nodes, the malicious attitude increases poor data transmission, increases energy use, and reduces the duration of the network. To address this issue, we proposed a new protocol, Trust-based Secure and Reliable Routing Protocol (TSRRP), to increase the trust between nodes in MANETs an...

Student's presence is marked after each student's identification. For the identification of student, a RFID based system is used. RFID method is considered to be the best and fastest method for identification. So, the framework is developed for managing the student's attendance. RFID reader is placed in the school bus, hence whenever the student boards into the bus, the students have to place their RFID tag to indicate the presence of arrival and departure. This RFID reader takes attendance electronically, and the records of the attendance are sent digitally to the school database. The database in turn generates a text message and sends it to the corresponding parents indicating the safer departure and arrival time of their children.

Spams which are also called unwanted, junk ,unsolicited mail is one of the major problem in using the e-mails. There are basically two things that are confused with each other that are one is Paper junk mail and spam mail, these two are usually confused

This is due to the public education about the disease, mode of spread and treatment available. The aim of the study is to review the epidemiology, clinical presentation, diagnostic methods available, organs affected and treatment available in the tertiary hospitals and outcome. MATERIALS AND METHODS Data Collection-Patients with upper right abdominal pain with radiological and ultrasound findings are included in the study. About twenty patients are taken for this study. Medical managements, surgical procedure done and outcomes are recorded, tabulated and analysed. Research Design-Prospective Study, Research Setting-KAPV Govt. Medical College and Mahatma Gandhi Memorial Govt. Hospital, Trichy, Tamilnadu. Duration-7 yrs. (2009 to 2016) Sample Size-Twenty. Inclusion Criteria-Patients between 12 to 70 years of age of both sexes. Patient having right upper abdomen or epigastric pain with positive radiological and ultrasound findings. Patient willing to participate in the study. Exclusion Criteria-Patients more than 70 years not willing to participate in the study patients absconded in between the management. RESULTS Liver is a commonest solid organ affected by the hydatid disease. Most of the diagnosis are made accidentally when the patients are investigated for some other diseases. The commonest clinical presentation is right abdominal or epigastric pain with hepatomegaly. The average age group is 45 years. X-ray abdomen, ultrasound abdomen are the most useful investigations. Asymptomatic uncomplicated small cyst less than 5 cms are managed with medical treatment. Symptomatic large cysts are submitted for surgical intervention. CONCLUSION The main source of income in majority of rural population is agriculture and sheep and cattle grazing. WHO is working towards the validation of effective cystic echinococcosis control strategies by 2020. At this juncture, we have to thank the Public Health Department and Veterinary Department for their effect in educating the public about the disease, especially about washing hands, mode of spread and treatment available in all peripheral hospitals and regularly deworming their dogs.

And the simulation results were verified by designing and building a test bench to collect gas phase diagram of texture induced oil film cav itation. Studies have shown that in the entrance area of the texture, due to a sudden change in the section, a negative pressure is generated; when the speed reaches a certain level, the negative pressure value reaches the cavitation pressure value of the o il film, causing cavitation of the oil film; And the cavitation effect can improve the oil film bearing and the lubrication effect of friction pair. The greater the speed, the more intense the degree of cavitation, the more obvious the imp rovement effect.
