Video Steganography : An Approach To Hide Text And Image Data using random coding

— Steganography refers to a file or info that has been concel (hide) within, video/audio file or a digital image. Steganography is employed to cover the messages within different harmless messages during a in a that doesn't allow any enemy to even sense that there's a second secret message present whereas the aim of computer forensics is that it provides security from covert communication managing digital information and covert communication channel. In this paper we tend to used video as cover media for concealment(hide) the secret message i.e text or images and we use random encoding/decoding process. For additional security, we used the random encoding/decoding process. Steganography is divided into Text Steganography, Image Steganography, Audio/Video Steganography. The experimental result shows that the original cover video and stego video are visually almost identical i.e. there's no perceptual difference between the 2 videos. In this paper we have a tendency to also analyze the histogram of the frames of the cover video & stego video, which doesnot show much difference.
Largest Obstacle of Drug Delivery to the Blood Brain Barrier and Current Approach to Solve this Problem: Recent Comprehensive Review

Brain is the most sensitive organ of human body. A few diseases like encephalitis, neurological disorders, various sclerosis, stroke, epilepsy, Alzheimer disease, Parkinson’s disease, different scleroses, headache and tumor prompt decline of brain function. The blood brain barriers excess the body to stay pathogens and potentially harmful chemicals circulating in the blood from entering the brain and spinal cord. The semi-permeable blockade, composed of tightly packed cells, is important for maintaining a controlled environment to excess the central nervous system (CNS) to function accurately. However, the barrier also makes it nearly impossible for many drugs and other drug molecules to be delivered to the brain via the bloodstream [1]. Neurological diseases are an important reason of mortality and constitute 12% of total deaths globally. Among the neurological disorders, Alzheimer and other dementias are probable to constitute 2.84% of the total deaths, while cerebrovascular disease constitutes about 8% of the total deaths in high income countries in 2005 [2]. development of new therapeutic approaches for these diseases is a difficult challenge, and there is no effective treatment for almost all the brain diseases. The blood-brain barrier (BBB) efficiently restricts penetration of therapeutic agents to the brain from the periphery [3].

Modulus Reconstruction by Simultaneous Data Response of Surface Stress and Strain Distribution

Medical imaging is vital to modern clinical practice, enabling clinicians to examine tissues inside the human body noninvasively. Its value depends on accuracy, resolution, and the image property (e.g., density). Various new scanning techniques are aimed at producing elasticity images related to mechanical properties (e.g., stiffness) to which conventional forms of ultrasound, X-ray and magnetic resonance imaging are insensitive. Elastography, palpography or strain imaging has been under development for almost two decades. Elasticity images are produced by estimating and analysing quasistatic deformations that occur between the acquisitions of multiple ultrasound images. Likely applications include improved diagnosis of breast cancer (which often presents as a stiff lump), but the technique can be unreliable and difficult to perform. In this paper a novel algorithm is proposed to find out the stress distribution from the strain distribution and stress value on the top surface of the Region of Interest (ROI). The comparison is also shown between the classical and the proposed method. Practical imaging is based on freehand scanning, i.e., the ultrasound probe is moved manually over the surface of the tissue. This requires that elasticity images are calculated fast to provide a live display, and the images need to present meaningful elasticity data despite the poorly controlled properties of the deformations. Stress distribution reconstruction is vital to find out the true value of the modulus distribution. Stress distribution only can predict based on different parameters. The modulus prediction error is minimized with a less number of iteration by using the proposed algorithm. It shows that only 6 iterations make the prediction error very close to 5% where as in conventional method it shows more than 12%.
Analysis of Data Delivery Technique with Vehicle Assisted Data Delivery for Data Dissemination

— he rapid evolution of wireless communication capabilities and vehicular technology would allow traffic data to be disseminated by traveling vehicles in the near future. Vehicular Ad hoc Networks (VANETs) are self-organizing networks that can significantly improve traffic safety and travel comfort, without requiring fixed infrastructure or centralized administration. However, data dissemination in VANET environment is a challenging task, mainly due to rapid changes in network topology and frequent fragmentation. In this paper we propose technique for data dissemination is Vehicle Assisted Data Delivery technique with carry forward method. The method adopts the idea of storing and carries and forward, where nodes carry the packet when there is no route and forward the packet to the new receiver that moves into its Direction. Different from existing carry and forward solutions and we makes use of the predictable vehicle mobility, which is limited by the traffic pattern and the road layout. The data forwarding path computed by vehicle-assisted data delivery method takes densely populated roads with high probability, which makes a suitable approach for forwarding data over sparsely connected VANETs. Therefore, even without end-to-end connection, the data packet can still be efficiently routed between vehicles and the roadside unit with high success rate and reasonable delay.
EFFICACY OF DICLOFENAC VERSUS COMBINATION OF IBUPROFEN AND PARACETAMOL, IN ACUTE LOW BACK PAIN WITH SCIATICA

Sciatica is a leading cause of low back pain. It is very common in young population of rural India. Paracetamol, non-steroidal anti-inflammatory drugs and muscle relaxants are commonly prescribed alone or in combination for the treatment of back pain. Various clinical trials were and are being conducted for the preferred NSAIDs for its efficacy, safety and tolerability in treatment of acute low back pain due to disc prolapsed. We conducted a double bind randomized controlled trial to compare the efficacy of diclofenac Sodium versus Ibuprofen and Paracetamol combination in acute disc prolapsed with sciatica. Post medication mean pain score (VAS) was 3.4 ± 1.73 for Diclofenac Sodium where as it was 2.7±0.63 for Ibuprofen+ Paracetamol combination. Mean TOPAR 8 hrs and 24hrs was 17.3±3and 58.4 ±12.4 respectively for Diclofenac Sodium where as it was 24.5 ±3 and 72.7 ±8.54 for Ibuprofen + Paracetamol combination. Mean SPID at 8 hrs was 10.0±3.55 with Diclofenac Sodium and 15.1±4.18 with combination. Adverse events in terms of nausea, gastritis, epigastric pain, flatulence, indigestion, hypersensitivity reaction, dizziness and discontinuation due to adverse reaction occurred in 237 patients on combined drug therapy where the number was 688 patients for Diclofenac Sodium. So it was concluded that on final assessment 70.8% of Ibuprofen + Paracetamol group rated their tolerability as “VERY GOOD” as compared to 50.89% of those in Diclofenac Sodium group. Moreover, Ibuprofen + Paracetamol shows a trend towards superiority in its efficacy and tolerability compared to diclofenac sodium.
Leakage Power Optimization by Sleepy Keeper Gate Replacement Techniques

: Power dissipation becoming a limiting factor in VLSI circuits and systems. Due to relatively high complexity of VLSI systems used in various applications, the power dissipation in CMOS inverter, arises from it’s switching activity, which is mainly influenced by the supply voltage and effective capacitance. One of challenge with technology scaling is the rapid increase in sub threshold leakage power due to Vt reduction. Leakage power dissipation is a component of static power dissipation in CMOS circuits. It is caused by the presence of leakage currents in the MOS transistors. Leakage power can be reduce by Stack, Sleep and Sleepy keeper transistor techniques. Sleepy Keeper technique provided lesser static power dissipation and lesser static power delay product in comparison with the other techniques. The main advantage of using Sleepy Keeper technique is that it retains the logic state and also lowers the sub threshold leakage power dissipation. It has been shown previously that the stacking of two off transistors has significantly reduced sub-threshold leakage compared to a single off transistor.
Hybrid Propulsion with Efficient Fueling System for Spacecraft

Current space launch vehicles use chemical reactions (solid and liquid propellants) to achieve sufficient thrust to launch spacecraft. They carry a lot of fuel to escape the Earth‟s gravity. For long-distance space-travel, more fuel is required. But more fuel increases the weight of the spacecraft and to minimize fuel consumption, the need for fuel-efficient spacecraft is necessary. It can make the deep-space manned mission possible. The ratio of payload and the overall weight of spacecraft are uneven; that means, to carry one ton of mass in space we require more than 100 tons of launch mass. For space colonization, space rockets should be able to carry a higher percentage of human beings with it. Currently, due to the overall weight and design of the spacecraft, it is not possible to carry number of people. Through the above mentioned four techniques, we can save the fuel of spacecraft at a large extent and can reduce its fuel consumption.
ESTIMATION OF INDOOR AND OUTDOOR EFFECTIVE DOSES FROM GAMMA DOSE RATES OF RESIDENTIAL BUILDINGS IN EMELEGO VILLAGE IN RIVERS STATE, NIGERIA

The health implications of exposure to radon gas (Rn ) by humans in the indoor environment is a major public concern worldwide. The aim of this paper is the measure the indoor and outdoor exposure rate at different heights and determines the annual effective dose and lifetime cancer risk of residents of six different settlements in Emelogu Community of Odua /Abua local Government Area of Rivers State. In-situ measurements of indoor and outdoor exposure rate of six different settlements were done using a well calibrated radiation Alert-100. The highest indoor and outdoor exposure rate of 0.0237 ± 0.014mRh and 0.0181±0.002mRh respectively were recorded in mud houses. The indoor annual effective dose ranges from 0.54mSvy for concrete not plastered houses to 0.949mSvy recorded in mud houses. Resulting average of the annual effective dose is 1.06 mSvy, which is large as compared to the worldwide average of the annual effective dose 0.48 mSv. Whereas outdoor effective doses calculated ranges from 0.204mSvy in burnt mud house to 0.253mSvy recorded around mud houses which results in total mean outdoor effective dose of 0.48mSvy. Estimated excess lifetime cancer risk (ELCR) from indoor AEDE ranges from 1.90 x 10 to 3.32 x 10 recorded in CNP and MD respectively and ELCR from outdoor ranges from 0.715x 10 to 0.887x 10 recorded burnt in mud house. Resulting average of the excess lifetime cancer risk is 4.21 x 10, which is large as compared to the resulting worldwide average 0.29 x 10. The reduction coefficients were obtained by taking the ratio of the indoor and outdoor dose rates. This paper shows that outdoor dose rates decreased as the measurement height increased, whereas the indoor dose rates increased as the height increased and that indoor dose rates at the centers of each houses were lower than other locations on this same room. Therefore residents should spend more time at the centers of their homes and also use smaller windows to reduce their exposure.
Information Flowtrack System for Presentation of Data using Mobile Cloud Framework

: Most would agree that modern app-markets have been flooded with applications that not only threaten the security of the OS superficially, but also in their majority, trample on user’s privacy through the exposure of sensitive information. The advances in technologies of cloud computing and mobile computing enable the newly emerging mobile cloud computing paradigm. Mobile cloud computing allows the execution of computation-intensive applications of mobile devices in computational clouds. A smart phone is the most widely used electronic device. Data over-collection which means smart phones apps collect users data more than its original function while within the permission scope is rapidly becoming one of the most frequent data over-collected cases. A mobile cloud framework is proposed to eradicate the data over-collection.
Compression of Visual Cryptography Shares Authenticated using QR Code

—Visual Cryptography is a Secret Image Sharing scheme which conceals a secret image into two or more images called shares. These shares are meaningless images and look like random dots. The secret image is recovered by stacking the shares. This paper proposes a novel method to authenticate so that only shares from authorized users are combined to reveal the secret image. This is done by first embedding QR Code (abbreviated from Quick Response Code) into the secret image, followed by the creation of shares. The original secret image is not affected as we embed the QR Code in non-region of interest. If a modified share or unauthorized share is superimposed on to the original share, the embedded QR Code cannot be read / retrieved from the resultant image. This signifies that one of the shares is not an authorized one. In VC the reconstructed image, encounter a major problem of pixel expansion. This is also solved in the proposed method by compressing the shares using a hybrid method that combines Vector Quantization and Run Length Encoding methods to achieve lossless compression. Decompression is done by applying decoding procedure and the shares are overlapped to view the secret image.
