1 A Hybrid Substrate Based U Shape Microstrip Patch Antenna for Wi-Fi and Wi-Max Range
Arvind Sahu and Dr. Kavita Burse

ABSTRACT - U shape microstrip patch antenna is one of the efficient antenna for 1 to 6 GHz. In the last decade there are different shape and size microstrip patch antenna introduced for Wi-Fi, WiMax ranges. In this range there are different bands occurs X, Ka and Ku etc. In the last decade researchers are try to improve the bandwidth and directivity of the microstrip patch antenna. For the improvement of the bandwidth researchers are used different substrate for like RT Duroid 5880, Teflon and PVC. In this research paper discuss noble combination of substrate for patch antenna. In the noble substrate use combination of FR4. Air and RT Duroid. When use this novel approach improve the number of bands, S-11 and VSWR. The proposed fusion of substrate apply in U shape microstrip patch with defected ground slot is presented. The proposed work also discuss different losses they are power loss, port loss, energy loss. Energy and power flow in the antenna in also discussed by the work. At the last compare the result of the proposed work with different previous methods that is shown in the table.
Keywords— Power loss, Energy losses, Metrals losses, Outgoing ports, Power Flow, Enegy Flow and RT duriod 5880 .

2 Conjunctive Keyword Search with Key Wrapping and Sponge Re Encryption Function for E-Health Clouds

ABSTRACT - As we all know that electronic health (e-health) record system becomes a novel application that will bring great convenience especially in the healthcare domain. This mainly came into existence in order to give security for the sensitive information of the patients who want to retrieve the information from the concern hospitals. Now a days the distributed healthcare systems under the roof of cloud computing server is used as a main facility for extracting the patient information among various health care service providers. This proposed thesis mainly concentrate on two things like one for data confidentiality and other one is to keep the patients identity very secure. Till now there are various primitive methods to control the access and provide the anonymous authentication, but they were not exploited according to the user need. In order to resolve all the above issues, in this proposed application we try to design and analyze the novel authorized privacy accessible model (APAM) for providing high level of security for the patient’s information which is accessed over online. By using this proposed model, the patients can authorize physicians by setting an access tree which takes the threshold value as input, then, based on the threshold value what we take, we try to design and analyze a new attribute based designated method for verifying the identity or signature of the patient whose data is stored in the cloud. By conducting various experiments on our proposed PSMPA model by taking some sample patient information files into the cloud, our simulation results clearly tell that our proposed model is best suited of providing security for the sensitive information, which is shared among multiple organizations. .
