All-optical demultiplexer of 10Gb/s channel dropped out of 40Gb/s data stream is demonstrated by using the method of four-wave mixing (FWM) and an optical filter. Demultiplexing of optical time division multiplexed (OTDM) signal is based on the effect of nonlinearities in a highly nonlinear fiber (HNLF).We describe our experiment of all-optical demultiplexer and bit error rate (BER) measurements.
In the present trend, CAN buses are implemented using software with the host computer monitoring the CAN as slave. Cause of which leads to bad reliability and real time performance. According to CAN specification version 2.0 of BOSCH gmbh, by downloading the IPcore to XILINX’s Spartan 6 FPGA, hardware implementation of customized Dual redundancy CAN bus Controller is put forward in this Paper. It’s verified that proposed design can meet the required real-time performance and reliability.

Digital surface Models (DSMs) contain information about topographic surfaces and also about other objects higher than the surrounding topographic surface such as buildings, trees etc. therefore, they are ideal for analyzing urban landscape. In this research DSMs of Bhopal city are made from Cartosat 1 stereo data. Three DSMs are made using three different techniques such as adaptive ATE, traditional ATE available through Leica Photogrammetric Suite (LPS) and automated terrain extraction available through Orthoengine. The paper compares the steps of DSM extraction and concluded that process of DSM generation comprised of image orientation and image matching. The output DSMs are compared in context of identifying urban features. It was found that DSM generated through traditional ATE and Orthoengine are more reliable compared to DSM generated through adaptive ATE. This is because; object filter within adaptive ATE modifies the elevation value resulting error in object heights.

Contractors with healthcare experience are well aware of the infection control risks associated with hospital renovation and construction projects. There’s no room for error on infection control so it’s critical to get the details right. A few specific measures can make a huge difference on construction projects in a healthcare environment.

Abstract- Disinfection is preventive efforts against the entry of pathogenic bacteria to the human body. Chlorination is one effort to give prevention with chlorine. The research objective was to determine of diffusion and mass transfer coefficients and then to develop of a chlorinated tool model. Effect of water flow rate on chlorine transport and granule size was studied to develop their relationship. The flow rates discharge used were 8 liters/minute, 14 liters/minute, and 20 liters/minute, whereas the granule sizes were 2.36 – 4.75 ml, 4.75-9.5 ml, and 9.5 - 16 ml. Diffusion coefficients and mass transfer determined by least summed of square of error. Diffusion coefficient and mass transfer used for disinfection technique was 0.4371 cm2 minute-1 and 0.0039-minute-1, as well as flow rate and granule size used was 9.5 ml - 16 ml and 8 liters/minute. Experiment testing of chlorination performed to ensure of them was potentially for chlorination.
Abstract- Indian Railway is world’s largest human transport system, is currently dealing with a lot of problems, such as availability of confirming seat if available during immediate cancellation / getting down at destination where other waiting list passesnger from that destination can board a train and reach the destination to avoid not allowing the other people who enter the train without buying tickets and then buy tickets from tc, reduce the burden of passenger to carry ticket. However there is no such system that presently in Indian railway gives accommodation to waiting list passengers during their journey and reducing the burden of carrying tickets. This paper proposes the new Seat Allocation system considering the advantage of QR code image that containts information about ticket and passenger info in form of 2d . Moreover, authentication seat allocation checking by tc is done using an another android app for tc which verifies qr code information with the database and redu
