Electromagnetic Compliance is the key factor in the modern industrial developments. The high speed devices in the advanced Engineering will lead to the electromagnetic interference problems. To cater the need of Electromagnetic Compliance it is essential for each and every electronics device to comply with such requirement. This can be done as a board level or component level. The other way of reaching...
Ranking web pages are generally based on in links and out links of a particular web page which may be exploited just to gain attention. Once weightage is calculated based on structural mining, the same may be excluded from the web page. Thus this approach is not trust worthy while calculating page importance for ranking. Research has been deviated from this traditional approach and started considering...
Robust control is becoming a necessity in almost all control fields. One method to achieve robust control in advanced control system is the two degree-of-freedom (2-DOF) control, in which two control loops will be assigned the performance and robustness goals separately. A Disturbance Observer (DOB), which is used in the designing of robust control systems, is a simpler and efficient tool. The applications...
Spectrally efficient orthogonal frequency division multiplexing (OFDM) offers an ideal solution to inter symbol interference (ISI), by maintaining the orthogonality among subcarriers. For a multi carrier (MC) communication system, the wireless channel impulse response (CIR) varies rapidly under severe channel fading conditions. In addition, estimating the channel characteristics under non-linear time...
With the hasty popularity of cloud computing data possessor are stimulated to move their intricate data from local repository to commercially available open cloud. We need to search and retrieve all the files which are semantically linked to the query in addition to the precise identical file in a secured manner. But for protecting sensitive information like military information, personal health documents...

PSPICE Simulation has been done for acquiring the reaction for the boost to the DGMOSFET based multiplexer outline. The most extreme deplete current got is 80 mA at an entryway source voltage of 5V and the variety of the deplete current as for deplete...
According to the WHO, the quantity of individuals getting influenced by glaucoma eye problems in worldwide will be approximately 80 million by the year 2020. Glaucoma is a perilous eye infection, which can prompt to perpetual vision misfortune if not gave appropriate treatment at the perfect time. Presently ophthalmologists distinguish the glaucoma sickness in view of estimation of container to plate...
This paper presents a simple yet effective method to determine the phase angle difference across any load connected to the supply. The proposed idea works on conditioning of the current and voltage signals in and across the load line and displays the phase difference through a Digital Panel Meter. It can indicate leading or lagging phase through a lead-lag indicator circuit. The authors simulated...
