Therefore, it needs some targeted drug delivery system to deliver the drug which would ensure relief from side effects along with the direct delivery of drug to the site of action in a controlled manner. Keeping in view the importance of mucoadhesive polymers in site specific drug delivery, in the present work, an attempt has been made to prepare, polysaccharide gum, PVA and AAm based mucoadhesive polymeric films for use as slow, site specific drug delivery system for oral cancer drug 5-flurouracil. Characterizations of polymers have been carried out by SEMs, EDAX, FTIR, TGA/DTA/DTG, XRD and swelling studies. The in vitro release dynamics of drug and some important biomedical properties of hydrogel films (like blood compatibility, mucoadhesion, tensile strength, relaxation, resilience and bursting strength) have also been studied. The values of maximum detachment force (F max) and work of adhesion (W ad) of) polymeric films have been observed (1.026±0.175 N) and (0.073±0.010 N mm) respectively. The release of drug in simulated saliva fluid occurred through Fickian diffusion mechanism and polymer films have been observed to be biocompatible nature.

The fast power transient effect of the cascaded erbium-doped fiber amplifiers (EDFA) in 45 channels optical ring network is investigated. The power transient effect of EDFA’s are observed when channels are added and dropped. It is shown that, for low channel adding/dropping frequency closed to EDFA transient rate, the transmission performances of the surviving channels are impaired severely. And also ring laser configuration technique has been reported to mitigate the effect of power transients. Optsim simulation was utilized for simulation of the designed DWDM OADM ring network.

Our phone is connected with things around us, even we can see live video of our home, shop, institute or company on the phone. But we can’t track suspicious activity 24*7 hence needed a smart system to track down any suspicious activity taking place, so it automatically notifies us before any robbery or dangerous activity takes place. We have proposed a framework to tackle down this security matter with the help of sensors enabled cameras(IoT) connected through a FOG layer hence called FOGIoT which consists of small servers configured with Human Activity Analysis Algorithm. Any suspicious activity analyzed will be reported to responsible personnel and the due action will be taken place.

Orthogonal frequency division multiplexing (OFDM) is a favorable approach for upcoming generation wireless communication systems. However its susceptibility to the frequency offset triggered by frequency difference between local oscillator of transmitter and receiver or due to Doppler shift results to Inter Carrier Interference.

In this paper simulation results are demonstrated for analyzing the effect of varying frequency offset factor on system’s error rate performance. Also the paper proposes the reduction in Inter Carrier Interference using the enhanced Data Conversion Technique with receive diversity for OFDM based wireless systems.

Ram Error Detection & Correction Using HVD Implementation

RAM memory cell contents can change spuriously due to some electromagnetic interference. In magnetic storage devices such as disks, magnetic flux density increases could cause one or more bits to flip (change that value). Exposure to high speed α ray particles is a prominent problem in all the semiconductor memories used for various communication applications. So, in this paper, an error detection and correction method to protect the RAM against the errors is proposed. This method is based on 2-d parities. The parity bits are calculated at the transmitter end for each row, column and diagonal in slash and backslash directions in a memory array. The parities are regenerated at the receiver end. The comparison of transmitted and received parity bits detects the error. As soon as the error is detected, the code corrects the detected error. This method is a promising technique to detect and correct errors in semiconductor memories in presence of large electromagnetic interference with less computational complexity.

It is used to compress a large amount of data into a small amount of bandwidth. This is possible by dividing a large amount of data into smaller parts, then sending that data simultaneously over a number of frequencies. OFDM allows a large amount of data to be transmitted quickly and reliably, with a minimum of loss or interference. As OFDM is used in various applications like Wi-Fi, 4G, DAB & WiMax, so its performance is an important factor and for this Bit Error ratio (BER) is calculated.This paper deals with the comparison between DWT based OFDM and FFT based OFDM for various digital modulation techniques and channel coding in terms of Bit error rate calculation. Simulation results shows that FFT based OFDM have better results as compared to DWT based OFDM.
