- M.K.Anandkumar,R .Gunasekaran, S.Agnalalex, V.Arthanareeswaran, C.Karthik, A.Kaviraj
Abstract
In this prroject, a class-D audio amplifier which combines the merits of the phase shifted carrier and the multiple level carrier. The proposed closed-loop amplifier includes a 2nd order integrator and a DLDPC triangular wave generator. High quality audio amplifiers should exhibit high power efficiency, while maintaining satisfying high fidelity to the human ear at the same time. Two sets of 180° out-of-phase triangular waves are used as carriers, and each set has its respectful offset voltage level with non-overlapping amplitude. By performing the double Fourier analysis, it can be found that the linearity can be enhanced and the distortion can be reduced with the proposed modulation. Experimental results shows that the proposed fully differential DLDPC PWM class-D audio amplifier feature a total harmonic distortion is lower than 0.01% with an output voltage swing of +or− 5V.

Flexural Strength of Self Compacting Concrete
- T.Sravana Sandhya, VenkataNarsireddy Sagili, Mohammed Hussain
Abstract
Concrete is often considered to be the ultimate construction material. Normal concrete is a vibrated concrete and it is dense aggregate mix that requires mechanical vibrations or poking to remove air pockets that become trapped during the pouring and mixing process. Hence to overcome these defects the self-compacting concrete is used. Although SCC was originally used in specialized situations, over time it became a superior alternative to conventional vibrated concretes. The self-compacting concrete flows easily at suitable speed into formwork without blocking through the reinforcement without being heavily vibrated. The major steps in the production of Self Compacting Concrete are proper design of mixes, the selection of admixtures that has the ability to maintain fluidity of mix and evaluating the properties of the concrete obtained. This project deals with the flexural strength of self- compacting concrete where the cement is partially replaced with fly-ash as10%, 20%, and 40% by weight of cement. . The optimized dosage of super plasticizer of 0.5% of powder content is used in each mix. The flexural strength characteristics are studied. Keyword: Self compacting concrete, fly ash, superplastisizers, flexural strength.×

Abstract
Data Mining is an interdisciplinary field of study for knowledge discovery from the large data sets. Collection of data, preprocessing, applying intelligent data mining techniques and interpretation are variou stages of data mining process. Out of which preprocessing is the critical part in data mining process. Noise, mislabelled data, imbalanced class, feature selection are some of the issues involved in preprocessing. In this research feature selection methodology has been considered for improving classification result for predicting Cardiotocography class. We have considered Correlation based Feature Selection(CFS), Symmetrical Uncertainty, ReliefF, Information Gain, Chi- Square feature selection methods and four different types of classifiers namely Jrip (Rule based), J48 (Tree based), NB (Bayes Learner), KNN (Lazy Learner). Proposed method has recorded some better result than considering all the features. Keyword: - - -.×

Thermodynamic Analysis in the Production of Chromium Carbide from the Reduction of Chromium Oxide with Methane-Containing Gas
- Romie D. Laranjo
Abstract
Thermodynamic calculation is done to determine whether the reactions will proceed or not. The more negative values of the Gibbs free energies would indicate that the reactions are going to proceed. The study aimed to determine the thermodynamic feasibility of using methane as a reductant for chromium oxide. It was thermodynamically proven that methane-containing gas is viable and highly suitable. Also, methane is cheaper and abundant thus, the cost of production in the Ferrochromium industry would be lessened eventually. Thermodynamic calculations further revealed that methane-containing gas was feasible in reducing Cr2O3 to chromium carbides based on the Gibbs free energies. Methane gas gave negative values of the Gibbs energies in all chromium carbides. It was observed that it was lower compared with the carbothermal and H2 reductions. Keyword: Computational thermodynamics, Gibbs free energy, ferrochromium, methane-containing gas, Reductant.×

Data Security in Cloud Environment Through Data Logs
- Prof. Sachin Darekar, Akshada J. Dherange, Kshitija B. Kadam, Pranjali B. Nikam.
Abstract
This Paper proposes use of public cloud for storing and accessing confidential data. Data confidentiality is assured by using encryption technique, in which the data is stored on public cloud is encrypted using encryption algorithm. The encryption algorithm used in encryption technique is AES.With the help of this method of using public cloud, the cost efficiency increases as public clouds provide many services such as service on demand, scalability, pay per use, inexpensive hardware set-up etc. There is a vulnerability to data security while using public cloud, since for confidentiality one has to rely on third party, but if encryption technique is used with data logging to keep track of the people accessing the cloud then the vulnerability to the data confidentiality can be eliminated. Keyword: SAAS, PAAS, IAAS, Encryption, Accountability, Logging, Cloud service provider.×

Forward Collision Alert on Stable Vehicles Using Ad-Hoc Network and Image Processing
- S.Mukesh Kumar, Yanamala Mahesh, Lokesh Babu, M.S.Kavitha
Abstract
The idea pitches and solves a specific case study alone. There are many crashes in recent years especially hitting a stable vehicle in roadswhich is halted due to some emergency or a breakdown condition. This can be prevented by prior forecasting of information between vehicles. The communication may be established by means of Ad-Hoc networks or Wi-Fi or any other radio circuits. Before sending a alert signal to the moving vehicle in the network, the network should check the vehicle in stable condition is on road or off road (Parked outside the road), some parameters (speed, direction of the car), GPS location. To check whether the car is on road it comprises two processes. The first one is by means of image processing. The camera is placed in the wind-shield or at the number plate of the car in a tilted angle. This system gets activated when the RPM or speed of the car reaches zero with a delay. As the system is activated the camera takes the image and sends image processing unit. The image processing unit splits the image into three. Then it checks for the content of blackness in each part. If the content of blackness is high, which send a value 1 otherwise 0. The outputs are collected from the three parts of the image and divided by 3. If the probability is 2/3, 3/3=1 then the probability of parking the vehicle on the road is high. If the probability is 1/3 then the probability of parking the vehicle on the road may be low. When the probability is low further the part is checked by the same process and derives the output finally.Goggle API the vehicle density is obtained. Based upon these outcomes decides the data to be sent or not. The output may be displayed in a display unit or mobile display unit or a dashboard alert.. Keyword: - - - .×
