One of the changes that the "Information Age" has brought to classrooms is that a Web-Based Classroom Management Support System (WBC) is now required for more efficient classroom management in elementary schools. This research aims at finding desirable Internet uses for more efficient classroom management through designing and implementing a web-based classroom support system. It has been possible to support classroom management beyond the limits of time and space with content found on the web and through guiding learners' internet usage in educational directions utilizing the resources on the web in more academic ways, and when applied in classrooms to help direct learners' active participation developing each learners' own special abilities and aptitudes. A WBC system is expected to offer upgraded classroom management

From decades, natural fibers in the form of reinforcements in polymer composites have been a test subject for scientists because of its growing familiarity wide range of applications. Banana (B) and Sisal(S) fibers are in good potential as reinforcement is polymer composite. The hybridisation of short Banana and Sisal fibers produces good properties compared to only Banana fiber.In this present work, an experimental study has been conducted to determine the effect ofonly banana fiber and effect of volume fraction namely B-S 20-20%, B-S 30-10% and B-S 10-30% on vibrational analysis parameters such as Natural frequency, damping ratio and mode shapes of Banana and Sisal fibers reinforced with epoxy resin Lapox L-12 using FFT analyzer. The nodes created on the test specimen is hit by an impact hammer causes the vibration which is detected by the sensor and converted in to V,I signal through transducer. These signals are amplified and magnified by signal conditioner generates the FRF curve and mode shapes.

Power quality problems in power systems have been improved due to nonlinear loads. To compensate these problems Direct Power Compensator was proposed in this paper. A Direct Power Compensator (DPC) is proposed in this paper to eliminate the harmonic currents, compensate power factor and voltage unbalance problems created by the nonlinear loads present in three phase systems. A DPC contains back to back converter by sharing the same dc link power and v/v transformer to provide a voltage balance in transmission line. Hysteresis harmonic current regulator is used to produce pulse for back to back converter. A controller maintains the dc-link voltage and compensates the power factor, harmonic currents. A comparative analysis for traction system with and without DPC was performed using MATLAB Simulink. Simulation results show the controller advantages and the applicability of the proposed method in railway systems.

HVAC power transmission using submarine power cables has limitation of charging current at nominal frequency. Therefore, HVDC power transmission technology has been established. However, a new intermediate technology of Low Frequency AC Transmission is established for transmission of power. This paper deals with the performance of a low-frequency ac (20Hz) transmission system for steady state. The LFAC system is interconnected with the 50Hz grid with a cycloconverter. The wind power from the offshore is in the form of dc, and is interconnected to the LFAC transmission line with a twelve-pulse thyristor inverter. The waveforms at the sending end and receiving end of the transmission line are plotted. The circuit model of LFAC system is simulated in MATLAB/SIMULINK.

The aim of this paper design and implement a key generator of cryptosystem that produces high security and random keys. The proposed generator includes many linear feedback shift registers. Each shift register has a shifting number in each encryption process that varies from other registers. A specific number of them are used in each encryption/decryption process. The selected registers are choosing depends on using tables that construction in the 23 field. To reduce the initial key and get random initial, the convolution multiplication is used to fill the initial values of registers. The generator uses in combining functions two logical operations, XOR and XNOR. From implementation of key generator and show the results of statistical test of randomness of key sequences samples, we show that the generator has good security.

The necessity for copyright protection, ownership verification, and other issues for digital data are getting more and more value these days. For the rapid revolution in digital multimedia and the ease of creating similar and unauthorized data, the digital data can be copied or manipulated or distributed. So it is necessary to watermark the media content for tamper proofing or quality assessment or copy control. In this paper we propose a JPEG2000 compression. The compression standard is chosen such that it provides higher compression ratio and the compressed byte stream are randomized by the encryption algorithm. In our paper watermarking was done in the compressed – encrypted domain. We use different watermarking techniques for this. Attempting to watermark such a randomized bit stream can cause a dramatic degradation of the media quality. Thus it is necessary to choose an encryption scheme that is both secure and will allow watermarking in a predictable manner in the compressed encrypted domain. The projected method is a robust watermarking algorithm to watermark JPEG2000 compressed and encrypted images (grayscale) of size 512×512. The encryption algorithm in this paper uses stream cipher. While the estimated technique embeds watermark in the compressed-encrypted domain, and the extraction of watermark can be done in the encrypted domain. The proposed algorithm also conserves the confidentiality of data as the embedding process can be done on encrypted data. The planned method can examine the PSNR and the security of the proposed algorithm, using the watermarking scheme: Spread Spectrum (SS) and Scalar Costa Scheme Quantization Index Modulation

Thane Municipal Corporation is located near to Mumbai City in Maharashtra State of India. Thane is growing rapidly since last few decades. The total area of Thane city is 128 Sq. Km. According to census 2011, total Population of city is 18.41 Lakhs and floating population is about 3 lakhs. The Solid Waste generation in the TMC area is around 650 MT per day. Out of which Plastic waste generation is about 60-70 MT per day. TMC don’t have any system for processing this plastic waste. This paper suggests a sustainable and one of the most emerging technologies of Plastic waste pyrolysis to TMC. Plastic Waste Pyrolysis is an ideal technology which is eco-friendly as well as generates furnace oil, carbon and hydrocarbon gas as productive output.
