American Beauty during both Kharif and Rabi seasons of 2007-08 and 2008-09. The experiments consisted of eight treatments with three replications, respectively were carried out by Randomized Complete Block Design. Days taken for spike emergence and first flower bud opening on the spike was, significantly less number of days (50.26 days) in T7 (40x20 cm, paired row mulching) followed by T1, T3, T5 (50.73, 51.27 and 51.63, respectively). The number of florets produced per spike, flower weight, flower yield per spike flower, yield per hectare recorded maximum in mulched plots with 30x20 spacing. There was increase in number of florets per spike, floret weight, floret yield per plot and per hectare was due to mulched plants i.e. T1, T3, T5 and T7 with single and paired row in both Kharif and Rabi season. The mulched plants like T1, T3, T5 and T7 with single row and paired row treatments showed significantly more number of corms, weight of corms, cormel number and cormel weight in mulched plots in both Kharif and Rabi seasons, respectively.Keywords

For data collection in various environments the wireless sensor networks (WSNs) is used. In that the sensor nodes are randomly deployed in large quantity, there is a broad range of applications supporting manual deployment. The sensors collect the raw data and forward to a remote base station (the sink) through a series of relay nodes. In the wireless communication environment, the operation time of a relay node depends on its traffic volume and communication range. Relay nodes are battery-limited. To get the maximum network lifetime, the location of the relay node have to be carefully planned. The deployment is ensure connectivity between the data sources and the sink, and also hold the heterogeneous traffic flows from different sources and the dominating many-to-one traffic pattern. For the simple case of one source node, both with single and multiple traffic flows produce the optimal solutions. However, the general form of the deployment problem is difficult, and the existing connectivity-guaranteed solutions cannot be directly applied here. The problem is then transformed into a generalized version of the Euclidean Steiner Minimum Tree problem (ESMT). Solution is in continuous space and may yield fractional numbers of relay nodes, where simple rounding of the solution can lead to poor performance. Thus the algorithms are developed for discrete relay node assignment, together with local adjustments. It yields the high-quality practical solutions. The solution has been evaluated through both numerical analysis and ns-2 simulations and compared with state-ofthe- art approaches. Traffic unaware strategies achieves up to 6 to 14 times improvement on the network lifetime.Keywords

Geocasting is done for the packet transmission within a particular region called geocast region. Geoaddressing and retransmissions are based on some local decision rules especially in Manets. In this paper, along with central distance calculation and priority queuing, the region based location routing method is introduced for scalability and drop rate reduction purposes. Here the automatic updating of location is done by individual nodes when it has a change in its location. The GPSN technology with node elevated repositioning is utilised here to improve the network scalability and deals with the node mobility problems and irregular topology. In previous works, the central region alone is considered for transmitting packets and the nodes are not much aware of all mobile neighbouring nodes location since each node follows the greedy transmission method leads to complexity in large networks. This method overcomes, when a node need not flows through central region and if every node knows well about their neighbour's location.Keywords

Search queries on databases, and often it return a large number of results, only a small subset of result are relevant to the user. Ranking and categorization, which can also be combined, have been proposed to alleviate this information overload problem. Results categorization for databases is the focus of this work. In this paper, we present the system is a novel search interface that enables the user to navigate large number of query results by organizing them using the concept hierarchy. First, the query results are organized navigation tree. Inside the navigation tree edge cut operation is performed. The query results returns the two set of results that is relevant to the user and ignore results. At each node expansion step, this system of results reveals only a small subset of the concept nodes, selected such that the expected user navigation cost is minimized. In contrast, previous works expand the hierarchy in a predefined static manner, without navigation cost modelling. We show that the problem of selecting the best concepts to reveal at each node expansion and propose an efficient heuristic as well as a feasible optimal algorithm for relatively small trees.Keywords

This paper presents the development of a methodology to manage and trace the vehicle velocity, temperature and position of the vehicle from the vehicular system .We proposed a automatic speed control system through analysis and monitoring through digitalized image sensing of the vehicle ahead and use color segmentation algorithms to have a position of the vehicle ahead, aiming predict a need of preventive maintenance and mostly avoids collision between the vehicles. In this proposed system, accelerometer which will identify vibration, temperature sensor to identify the temperatures at critical points of vehicle, a microcontroller hardware which will make acquisition and processing of signals from sensors. The acquired parameters such as Vehicular speed, position and temperature are stored in a SD card and finally The vehicles sends information to the Emergency services, respective mobile numbers. The post processing is performed remotely through a computer that receives the data submitted via GSM presenting them to the user via graphical interface. This leads to minimize collision in highways.

Due to advances in control configurations, classical PID controllers are replaced with modern PID controllers to yield satisfactory performance. It is very essential to design a modern PID controller to achieve optimal control with dead time compensation, reduced overshoot, reduced settling time and non-oscillatory output. The controller attempts to minimize the error over time by adjustment of a control variable, such as the position of a control valve, a damper, the power supplied to a heating element or temperature control systems. An attempt is taken to design a modern PID controller for stable systems that would produce optimal output with reduced dead time and the safety of the system is ensured.

In this modern world, there has been a great deal of focus on power quality management in industrial applications. The embedded software application requires performing a task which is efficiently achieved by dividing the global task into many smaller subtasks. Each subtask apart from executing its own task, services a part of the global task.RTX is the RTOS that powers more than one billion real-time systems across the globe, from small consumer products to commercial airliners. When the consequences for failure are expensive or worse, life-threatening, RTX RTOS is the only choice. The concept of dynamic assignment of priorities to interrupts is used which reduces the time delay for a lower priority task under some circumstances becomes a higher priority task. Slicing of interrupt timings improves the performance. The highest priority task is serviced more number of times than the lesser time period. Voltage sensor and current sensor are interfaced to microcontroller, the capacitor bank is powered and the power factor produced from the location is gathered and depending on the particular criteria, The capacitor banks are switched ON to a controllable and variable amount of reactive power according to the requirements of load such that the power factor is improved and the uninterrupted working is done.Keywords

Data gathering is a process of collecting more number of data from distributed sensor nodes and sends these data to sink node. During the data gathering, energy consumption (EC) is a major concern for enhancing the network lifetime (NL). Several WSN architectures have been developed to resolve this problem In order to improve the data gathering efficiency, AdaBoost Nonlinear Regression Tree Classification (ABNRTC) technique is developed. ABNRTC technique improves the data gathering with minimal EC. Initially, energy of each senor nodes is measured. After that, mobile sink node gathers the sensed information from the high energy sensor nodes with minimum delay. Then the mobile sink node classifies the collected data packet using nonlinear regression tree based on their relationship among the sensor nodes in WSN. The relationship between the data packets are measured using population Pearson product-moment correlation coefficient. AdaBoost algorithm is a boosting technique for grouping the several weak nonlinear regression tree classifiers to make a single final output of boosted classifier. Finally, the classified data packets are sent to base stations (BS). Simulation of ABNRTC technique is carried out with different parameters such as EC, NL, data gathering efficiency, delay, classification accuracy (CA), false positive rate (FPR) and classification time (CT).Keywords
