Many types of wastewater treatments are available now a day. Out of these various wastewater treatment methods available Fluidised Bed Biofilm Technology is a very recent innovation in the wastewater treatment. This study mainly focuses on the removal of nitrate from the wastewater i.e. biodenitrification of wastewater. In this study experiments on a Fluidised bed biofilm reactor set up are carried out by the use of waste roofing construction tiles (specially crushed roofing mangalore tiles) as a biofilm carrier media which is used as a substitute over the conventional high cost biofilm carrier media. The FBBR set up is run at different varying hydraulic loading rates and the concentration of the nitrate is measured both at the inlet and outlet end of the set up along with measuring the other chemical characteristics such as COD and pH. Based on these results graphs are drawn and results are compared with other biofilm carrier material. Results states that the use of waste roofing construction tiles can be used with high advantage in the FBBR technology. The maximum average nitrate removal efficiency obtained is 59.02% at an HRT of 5 minutes. Hence use of this technology and biofilm media proves a sustainable option for conventional wastewater treatment.

Stress leads to generation of reactive oxygen species (ROS) in living cells, which are scavenged by antioxidant enzymes. Effect of UV-B stress on transgenic tobacco (Nicotiana tabacum cv. Xanthi) overexpressing cytosolic superoxide dismutase (AhCuZnSOD) and untransformed control plants were compared. Transgenic tobacco plants exhibited higher levels of total antioxidant enzyme activities, lower level of malonyldialdehyde content and hydrogen peroxide accumulation under stress conditions in comparison to the untransformed control (UC) plants. Our analysis revealed that antioxidant enzyme leads to increase in the total activity of the antioxidant ezymes and thus improve UV stress tolerance in transgenic plants.

Interconnection increases the delay, area and energy consumption in complementary metal oxide semiconductor (CMOS) digital circuit. For design circuitry in VLSI, multiple-valued logic (MVL) plays a very vital role. Multiple-valued logic is an apparent extension of binary logic where any proposition can have more than two values. Average power requirement can be decreased using the concept of level transition in multiple-valued logic. MVL is also helps to reduce the number of interconnections. It provides the key benefit of higher density per integrated circuit area compared to traditional binary logic. In this paper, we present an application of these circuits with response to Galois field operations and also present a quaternary converter circuits using Down Literal Circuit (DLC). Arithmetic operations such as addition and multiplication are the two basic operations in Galois field. Tanner has created a software platform that is cost-effective and easy to use.

Information and communication technology has brought enormous changes to our life. With the increase of data transmission and hence source of noise and interference, engineers have been struggling with the demand for more efficient and reliable techniques for detecting and correcting errors in received data. Although several techniques and approaches have been proposed and applied in the last decade, data reliability in transmission is still a problem. Error detection and correction techniques are therefore required. Among other techniques such as Cyclic Redundancy Check and Solomon Codes; orthogonal coding is one of the codes which can detect errors and correct corrupted data in an efficient way. An n-bit orthogonal code has n/2 1s and n/2 0s. In a previous work these properties have been exploited to detect and correct errors. In this review paper we discussed a new methodology to enhance error detection capabilities of the orthogonal code.

In this paper we consider security of internet access over the Third Generation (3G) telecommunication systems. We Consider Universal Mobile Telecommunications System (UMTS) is selected as the most popular system among 3G systems. Here we detecting and removing DDos attack in UMTS network. The study then focuses on network access security mechanism of UMTS denial of service, identity catching, and redirection as the most significant attacks against authentication mechanism. Furthermore, we provide some solutions and methods to improve and prevent these attacks in UMTS system. The Universal Mobile Telecommunication System, more commonly known as UMTS, is now the world’s leading mobile telecommunication system serving over 4 billion subscribers worldwide. UMTS has got much popularity as the earlier GSM system failed to cope up with higher data rate demands and faced some major security flaws. Although the UMTS system is able to mitigate most of those security flaws, yet it is not invincible to the new threats emerging with new and more sophisticated technologies. Many different kinds of security breaches are possible against UMTS networks. In this short technical essay, we will focus only on the Denial of Service (DoS) attacks on the UMTS access network, we replace GSM network with UMTS network because of security flaws. Distributed Denial of Service (DDoS) attacks exhaust victim’s bandwidth or services. In this paper, different types and techniques of DDoS attacks and their countermeasures are reviewed. We also discuss some traditional methods of defence such as trace back and packet filtering techniques so that readers can identify major differences between traditional and current techniques of defence against DDoS attacks. Before the discussion on countermeasures, we mention different attack types under DDoS with traditional and advanced schemes while some information on DDoS trends in the year 2012 Quarter-1 is also provided. We identify that application layer DDoS attacks possess the ability to produce greater impact on the victim as they are driven by legitimate-like traffic making it quite difficult to identify and distinguish from legitimate requests. The need of improved defence against such attacks is therefore more demanding in research. The study conducted in this paper can be helpful for readers and researchers to recognize better techniques of defence in current times against DDoS attacks and contribute with more research on the topic in the light of future challenges identified in this paper.

Automatic image matching technique when applied to high resolution space images generate point cloud data describing the surface. A DSM is an elevation model of surface reflectance features and includes the height of cultural features such as buildings, roads and vegetation as well as bare earth. The surface model thus defined needs to be converted to 'bare- earth model' DEM before it can be used for any natural resource applications. Here in this study area an attempt has been made to improve the elevation accuracy of Cartosat-1 DSM which is generated using Augmented Stereo Strip Triangulation developed by ISRO, using high precision ground control points. The Cartosat-1 DSM is having a posting of 10m. The improvement in elevation accuracy is achieved by applying bias correction using ICESat/GLAS points and slope based filtering. For bias corrections the points falling on the ground are taken and other points are excluded in computation as they are treated as outliers. For the study area of Gandhak area covering 19,250 Sq. Km, the RMSE and Absolute LE90 for input DSM is 5.96m and 6.25m respectively. For the output DEM the RMSE and Absolute LE90 is 1.98 m and 2.08 m respectively. Statistical validation of input DSM and output DEM with ground control points shows an improvement of 4.17m in Absolute LE90 for output DEM with respect to input DSM. The values for output DEM shows that the 90% of elevations are within 2.08 m when compared with reference points. To access the output quality of DEM derivatives of DEM, drainage and contours are generated. The output DEM derived from filtering methods depicts the continuity in drainage network and contours along the river. Many isolated contours formed in DSM in vegetation areas are removed in the output DEM. Drainage continuity is very much useful for runoff and discharge flow estimation which are critical parameters for hydrological modelling. This study aptly demonstrates the improvement in elevation accuracy of Cartosat-1 DSM using ICESat/GLAS data and slope based filtering methods.
