This paper reports the results of some experimental studies on the use of different types of manufactured sand in cement mortar. Granulated Blast Furnace Slag (GBFS) sand which is a ferrous slag and Crushed Granite Sand (CGS) obtained from vertical cone crusher are considered. These two are the generally used alternative sand in India for use in mortar and concrete. In this investigation, cement mortar mix 1:3 and the replacement of Natural Sand (NS) by GBFS and CGS at various percentages is considered at different water cement ratios namely 0.4, 0.5 and 0.6. With the addition of manufactured sand the workability of mortar in terms of flow decreases gradually as the replacement level increases. This is mainly due to irregular features of the surface characteristics and also due to higher water absorption capacity. The manufactured sand exhibited better strength due to good bond characteristics. The reduction in flow varies over a wide range depending on the type and percentage of replacement levels. This loss in flow can be adjusted by adding suitable dosage of superplasticiser. From this study it is observed that the manufactured sand is a good alternative for the natural river sand in mortar provided the workability is compensated by adding suitable dosage of plasticiser. In spite of this, manufactured sand is quite economical. In addition durability studies are necessary for making concrete conclusions.

Time series signal is a continuous signal which varies continuously with respect to time. The information content in these signals can be used for Feature Extraction, Classification and forecasting.The purpose of Feature Extraction is to reduce the dimension of feature space and achieving better performances. The Features are extractedbased on the mathematical calculations like Average, Maximum, Minimum, Standard Deviation and Variance. The Classification of extracted features is carried out byFuzzy Rule based Selection System. In this paper mamdani based Fuzzy System is used to achieve accurate results. Based on feature extracted data the Fuzzy System generates a fuzzy score and the Classifier Algorithm classifies the feature extracted signals as Good, Bad and Best signals.The purpose of Forecasting of a time series signal is to extracts some new useful information contained in large datasets. The Forecasting of time series signal is achieved by usingGARCH model. GARCH model has a good prediction power and the achieved performance differs from one period of time to another, depending on the volatility structure of the time series signal.

Without any pre-existing fixed network infrastructure with rapid configuration of wireless connections on-the-fly, network topology in MANETs keep on changing rapidly. Thus achieving data transmissions between wireless nodes in MANETs with improved QoS parameters become a challenging issue. To achieve this one has to concentrate on the routing protocol they choose. In our paper we proposed an algorithm to provide improved quality of service via hybrid routing protocol-Zone Routing Protocol (ZRP). We have considered two reactive routing protocols Dynamic Source Routing (DSR) and Ad hoc On Demand Distance Vector (AODV) as reference for analyzing ZRP by considering route acquisition delay and quick route reconfiguration during link failure. These parameters viz., route acquisition delay and quick route reconfiguration have their impact on increase in end to end delay, this automatically decreases the number of packets received thus the throughput. We used well known network simulator QualNet version 4.5 to compare QoS parameters viz., throughput, number of bytes received, average end-to-end delay for DSR, AODV and ZRP. © 2010 IEEE.

The oxidative behavior of diclofenac sodium (DCF) has been investigated by cyclic voltammetric and differential pulse voltammetric techniques, using a Tyrosine-modified carbon paste electrode (TCPE). Cyclic voltammetry was used to study the influence of pH on the anodic peak current of DCF. The solution conditions and operating parameters were optimized. The phosphate buffer (PBS) of pH 7.0 was selected as a suitable analytical medium in which DCF exhibited a sensitive diffusion-controlled oxidative peak at 0.67 V (vs Ag/AgCl). The peak current varied linearly with DCF concentration in the range between 10 μM and 140 μM with a detection limit of 3.28 μM. The applicability of the proposed method was illustrated by the determination of DCF present in pharmaceutical samples and human urine samples. A mean recovery of DCF in the tablet was 99.5%, with a relative standard deviation of 1.15%. © 2012 American Chemical Society.

The electrochemical behaviour of lawsone at glassy carbon electrode (GCE) was investigated by using cyclic and differential pulse anodic stripping voltammetric (DPASV) techniques. Cyclic voltammetry was used to study the influence of pH on the peak current and peak potential. The Mcllavnie's buffer of pH 3.0 was selected as a suitable analytical medium in which lawsone exhibited sensitive diffusion controlled redox peaks (vs. Ag/AgCl). The peak current varied linearly with lawsone concentration in the range between 0.60 and 1.40 μM with a detection limit of 6 nM. The applicability of the proposed method was illustrated by the determination of lawsone present in real samples. A mean recovery of lawsone in the leaf of Lawsonia inermis was 99.5% with a relative standard deviation of 1.15%. © 2014 Pleiades Publishing, Ltd.

In this paper, we unified two new algorithms, i.e., to selectively Bordercast the control packets in order to reduce the network load by limiting the number of control packets when ZRP searches for a new route. The second algorithm is proposed to optimize the performance of Query control mechanisms for the Zone Routing Protocol (ZRP) for mobile ad hoc networks for communication on an urban terrain. ZRP proactively maintains routing information for a local neighbourhood (routing zone), while reactively acquiring routes to destinations beyond the routing zone. This hybrid routing approach can be more efficient than traditional Zone Routing Protocol (ZRP) framework. However, without proper query control techniques, the ZRP cannot provide the expected reduction in the control traffic. Our proposed algorithm enhances the structure of the routing zone to provide enhanced detection and prevention of overlapping queries. These techniques can be applied to single or multiple channel mobile adhoc networks to improve both the delay and control traffic performance of ZRP. Our new algorithm allows ZRP to provide routes to all accessible network nodes, with less control traffic than purely proactive link state or purely reactive route discovery, and with less delay than conventional flood searching. The performance evaluation via simulations using a well known simulator QualNet version 5.0 shows that the new approach has better performance than the traditional ZRP. ©2010 IEEE.
