http://ijaems.com/ Open Access international Journal to publish research paper en-us April 2015 Water provided to the consumers, must be safe and should meet each health quality standards and aesthetic needs like color, turbidity, style and odour. Current waste product observance techniques deem the employment of nutrients detection because the results of some reaction that is undesirable for long-run use in time period applications. Additionally, new legislation could render such systems obsolete if they can't dependably verify the quantity of nutrients in waste product relative to allowable levels. This paper makes an attempt to deal with this issue by considering the employment of microwave sensing techniques as another time period approach that has the potential to observe waste product nutrients like phosphate and nitrate. The tactic utilizes a broad vary of microwave frequencies (1-15 GHz) and is incontestable with 2 differing kinds of structure for this purpose, specifically a conventional resonant cavity and a versatile inter digitated conductor structure. Research lab read package used for analysis of captured information and for straightforward user interpretation of this information is additionally incontestable. Future work to be undertaken is mentioned in reference to rising the performance of the sensing element any, moreover as adding the aptitude to mechanically verify each the sort and concentration of nutrients in water solutions. A variety of experimental results square measure shown that validate the relevancy of the microwave sensing for detection phosphates and nitrates within the solutions. http://ijaems.com/detail/a-review-on-micro-sensors-for-detection-of-nutrients-in-water/ Rajendra Singh, Mahendra Kumar http://ijaems.com/upload_images/issue_files/1452608077-IJAEMS-APR-2015-1.pdf This paper presents web search has demonstrated in improving the quality of various search services on the internet, user reluctance to disclose the private information during search has become major barrier for the wide proliferation of password. Protection in password authentication model user preferences as hierarchical user profiles, a password framework know as user profile search that can adaptively generalize profile by search query while respecting user specified privacy requirements. Our work provides utility of personalization and the privacy risk of exposing the generalized profile using Greedy algorithm is a method for deciding whether personalizing a query is efficient. http://ijaems.com/detail/privacy-protection-in-web-search/ Rekha Joshi http://ijaems.com/upload_images/issue_files/1452608702-IJAEMS-APR-2015-2.pdf Ad-hoc wireless networks are an exciting research direction in sensing and pervasive computing. Advance security work in this area has beenprimarily focused on denial of communication at the routing or medium access control levels. There is a common attack at routing protocol layer, i.e. resource depletion attack, which permanently disables networks by drastically draining nodes’ battery power. These “Vampire” attacks are not similar to any specific protocol, but rather depend upon the properties of many popular classes of routing protocols like link state and DSR protocols. These vampire attacks are very difficult to detect, devastating and easy to carry out using as few as one malicious insider sending only protocol compliant messages. For mitigation of these kinds of attacks, some methods are explained, including a new proof-of-concept protocol that provably bounds the damage caused by Vampires during the packet forwarding phase. http://ijaems.com/detail/mitigation-of-vampire-attacks-in-wireless-adhoc-and-sensor-networks-during-packet-forwarding-phase/ Ghyanshyam Meena, Mrs. Sankuntala Sharma http://ijaems.com/upload_images/issue_files/1452608878-IJAEMS-APR-2015-3.pdf This paper presents our attempt to recover back energy that is stored in the bit lines and in the cell and reused it by a phenomenal technique of energy recovery known as adiabatic principles. By the application of this adiabatic driver the loss of energy to the ground during ‘1’to‘0’ transition in SRAM is reduced to a greater degree. In this paper the performance of the conventional 6T SRAM circuit is compared with the performance of the Adiabatic 6T SRAM. In the adiabatic SRAM good high degree of power reduction is reported. By applying the aforementioned technique same SRAM is investigated by varying technology. Another parameter such as delay and power delay product (PDP) is also been calculated for all the SRAM. All the circuits are simulated in HSPICE and delay is calculated using Cosmo scope. http://ijaems.com/detail/parametric-reliability-of-low-power-adiabatic-sram/ Rakesh Kumar, Abhishek Kumar http://ijaems.com/upload_images/issue_files/1452609071-IJAEMS-APR-2015-4.pdf This paper strives to make an impact on Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar which locates precipitation and estimates its type (rain, snow, hail etc.). Soon after the World War II, surplus radars were used and since then, weather radar has evolved and is now used by national weather services and research departments. Modern weather radars i.e. Doppler radars are capable of detecting the motion of rain droplets in addition to the intensity of the precipitation to determine the structure of storms and their potential to cause severe weather. Hence, it is a key forecasting tool. Weather radars send directional pulses of microwave radiation, on the order of a microsecond long, using a cavity magnetron or klystron tube connected by a waveguide to a parabolic antenna and receives the return signals from particles in the air on the order of a millisecond, which is a thousand times longer than the pulse duration. http://ijaems.com/detail/a-review-on-weather-surveillance-radar/ Abhishek Kumar, Dharmveer Singh http://ijaems.com/upload_images/issue_files/1452609259-IJAEMS-APR-2015-5.pdf
