On-demand availability of various data as services in a shared and automated environment has become a reality with the advent of cloud computing. The digital fingerprinting technique has been adopted as an effective solution to protect the copyright and privacy of digital properties from illegal distribution and identification of malicious traitors over the cloud. Furthermore, it is used to trace the unauthorized distribution and the user of multimedia content distributed through the cloud. In this paper, we propose a novel fingerprinting technique for the cloud environment to protect numeric attributes in relational databases for digital privacy management. The proposed solution with the novel fingerprinting scheme is robust and efficient. It can address challenges such...

In this method 2-butanol and chloroform were used as dispersing media and the materials were tested for corrosion protection of stainless steel in Indian Ocean water. The amount of aniline, oxidant (Benzoyl peroxide), Dodecylbenzenesulphonic acid (DBSA) surfactant and metal oxide (TiO2) were varied in the reaction bath for optimum yield. The as-synthesized PANI and PANI-TiO2 composites were soluble in a number of common organic solvents and characterized with Ultravilot-visivble (UV-Vis) and Fourier Transform Infra-Red (FT-IR) spectroscopies. The surface morphology, particle size and crystinality were determined with Scanning Electron Microscopy (SEM) and XRays Diffraction (XRD) analysis. Thermogravimetric analysis (TGA) was employed to determine thermal stability of the composite. The total mass loss was found to be 58% in PANI as compared to 22% in PANI-TiO2 showing comparatively higher thermal stability of the composites. The composites were electrochemically active in acidic medium and reduced corrosion rate of steel to 0.9083 mm/ year Indian Ocean water. Finally it was concluded that PANI-TiO2 composites could be employed as anticorrosive coatings for steel in aggressive corrosive environment

After analyzing PE scheme and its shortage, a group key distribution scheme utilizing a polynomial expansion with multi-seed(M-PE)is proposed. Its operation is demonstrated by using multi-seed, the group member is partitioned to many subgroups. While updating the SEK, computation is needed only in one of subgroups, the other of them will use the computation history to update their SEK. A prototype test system is designed in order to validate our new scheme especially for its computable complexity. In the system, a kind of technology of producing a strict prime number is introduced as well as a table is designed in order to reduce the computation complexity.

However, the combine effects of smoke with plant hormones on seed germination remain unknown. This investigation describes how lettuce (Lactuca sativa) seeds respond to smoke solution and how the smoke solution can alleviate abscisic acid (ABA) stress. The results showed that plant extracted smoke treated seeds had significantly quicker germination, higher germination percentage, fresh weight, relative seed germination percentage, peak value, germination value, shoot and root length, germination index and vigor index as compared to control. No germination was observed in ABA (0.1mM) treated seeds but significant number of seeds germinated when ABA and smoke solutions were mixed together. It was observed that smoke solutions overcome the inhibitory effects of ABA and improved germination and seedling vigor, indicating that smoke alleviated ABA stress not only at the germination level but also at seedling stage.

Fingerprinting techniques ensure ownership protection and tamper proofing and help in identifying the guilty agent who is responsible for the data leakage. However, these techniques are not robust when the guilty agent attacks the data in a large amount. In this paper a novel and robust, fingerprinting technique is proposed through employing Genetic Algorithm (GA) - a biologically inspired evolutionary computation technique. The robustness of the proposed technique is demonstrated against collusion, deletion and alteration attacks.

These databases are used effectively in collaborative environments for information extraction; consequently, they are vulnerable to security threats concerning ownership rights and data tampering. Watermarking is advocated to enforce ownership rights over shared relational data and for providing a means for tackling data tampering. When ownership rights are enforced using watermarking, the underlying data undergoes certain modifications; as a result of which, the data quality gets compromised. Reversible watermarking is employed to ensure data quality along-with data recovery. However, such techniques are usually not robust against malicious attacks and do not provide any mechanism to selectively watermark a particular attribute by taking into account its role in knowledge discovery. Therefore, reversible watermarking is required that ensures; (i) watermark encoding and decoding by accounting for the role of all the features in knowledge discovery; and, (ii) original data recovery in the presence of active malicious attacks. In this paper, a robust and semi-blind reversible watermarking (RRW) technique for numerical relational data has been proposed that addresses the above objectives. Experimental studies prove the effectiveness of RRW against malicious attacks and show that the proposed technique outperforms existing ones.

The accuracy of these biological phenomena depend on genetic codes and all subsequent processes. To computerize the biological procedures, different domain experts are provided with the authorized access of the genetic codes; as a consequence, the ownership protection of such data is inevitable. For this purpose, watermarks serve as the proof of ownership of data. While protecting data, embedded hidden messages (watermarks) influence the genetic data; therefore, the accurate execution of the relevant processes and the overall result becomes questionable. Most of the DNA based watermarking techniques modify the genetic data and are therefore vulnerable to information loss. Distortion-free techniques make sure that no modifications occur during watermarking; however, they are fragile to malicious attacks and therefore cannot be used for ownership protection (particularly, in presence of a threat model). Therefore, there is a need for a technique that must be robust and should also prevent unwanted modifications. In this spirit, a watermarking technique with aforementioned characteristics has been proposed in this paper. The proposed technique makes sure that: (i) the ownership rights are protected by means of a robust watermark; and (ii) the integrity of genetic data is preserved. The proposed technique-GenInfoGuard-ensures its robustness through the "watermark encoding" in permuted values, and exhibits high decoding accuracy against various malicious attacks.

Many studies have shown that continued aspirin therapy reduces postoperative myocardial infarction and increases survival. The purpose of this study is to analyze the effect of preoperative aspirin on postoperative bleeding in patients undergoing CABG. Patients (n=30) undergoing CABG were divided into two groups, group 1 (n=15) who received aspirin till the day of surgery, and group 2 in whom aspirin was stopped 5 days before surgery. Postoperative bleeding up to 76 h (approximately 3 days) was noted in both groups. Preoperative, intraoperative, and postoperative variables were equal in both groups. Postoperative bleeding in the 2nd hour was significantly lower in group 1 compared to group 2 (p=0.004). Bleeding 28-76 h postoperatively was also significantly lower in the first group (p=0.043). Our study suggests that...

It is shown in this study that a vehicle, equipped with the ability of a V2G application, offers various features such as regulation of active power, support for reactive power, load balancing, current harmonics filtering etc. These features can enable ancillary services including, spinning reserve and control of voltage and frequency. However, the technology of V2G also creates challenging issues, for instance, degradation of batteries, communication overhead between an EV and a grid, changes in whole infrastructure of a distribution network (DN). This paper shows the present scenarios and analyze the impact of implementation V2G & G2V modes on DNs. V2G system have an impact on major factors of electric grid like reliability, efficiency, losses, and system stability. Our study also shows that the economic benefits of a V2G technology heavily depend on the strategies of charging and vehicle aggregation.
