QoS Multicast routing is difficult in Mobile Ad hoc Network (MANET) due to limited resources. Each node in MANET is constrained by their limited battery power for their energy. The energy is reduced as the time goes off due to the packet transmission and reception. Energy management techniques are necessary to minimize the total power consumption of all the nodes in the network in order to maximize its life span. Our proposed protocol Energy Reduction Aware Multicast (ERAM) aimed to find a path which utilizes the minimum energy to transmit the packets between the source and the destination. The required energy for the transmission and reception of data is evaluated at the MAC layer. The network layer makes use of it to find the minimum energy path. ERAM is implemented on Multicast Ad hoc On Demand Distance Vector Routing Protocol (MAODV) to manage the energy consumption in the transmission and reception of data. Simulation results of ERAM show the energy consumption has been reduced.Keywords

Background/Objectives: Multilevel Inverters are growing technology, even there are many topologies available in real world, here new multilevel topologies such as diode clamped multilevel inverter and cascaded-H-bridge inverter are discussed and comparative results for lower total harmonic distortion are analysed. Methods/Statistical Analysis: Neutral point diode clamped inverter is analysed and its total harmonic distortion value is calculated. Cascaded H-Bridge (CHB) 7 level inverter is analysed and then simulated, finally it is verified using FPGA controller. Three H-bridges are seriously connected to produce 7 level output voltage, FPGA controller uses Sinusoidal Pulse Width Modulation (SPWM) to produce pulse pattern for H-bridges. Results: This topology is tested in Matlab/Simulink environment. Total Harmonic Distortion (T.H.D) value of 7 level voltages is seen as a 30.33%. Which is very low as compared with 3 phase diode clamped five level inverter (81.7%). Conclusion/Application: Solar Photo Voltaic system is employed to compete the disadvantages of conventional energy sources and resulted in energy conservation system that reduces power consumption.Keywords

Mobile Ad-hoc Network (MANET) is a self-configuring infrastructureless network of mobile devices connected by wireless links. Each device in a MANET is free to move independently in any direction, and will therefore change its links to other devices frequently. MANET does not require any fixed infrastructure and it is capable of self configuring, these unique characteristics made MANET ideal to be deployed in a remote or mission critical area like military use or remote exploration. However, the open medium and wide distribution of nodes in MANET leave it vulnerable to various means of attacks. This paper proposes a TAODV for improving security in adhoc routing protocol. The proposed TAODV detects the network layer attacks like blackhole and wormhole attack and rectifies it by using the trust values. This proposed scheme is based on incentives and penalties depending on the behavior of the nodes in the network. The TAODV allow the source node to choose the trusted and the shortest path during the route discovery and isolate malicious node in the network.Keywords

Transformer is one of the key components in a power system. It can experience thermal and electrical stresses during its operation. The mineral oil and the insulation paper used in transformer can undergo chemical changes under these stresses and gases are generated. These gases dissolve in mineral oil. The gases dissolved in oil are extracted in the laboratory using gas chromatograph. The gas content and the type of gas can reveal the nature of fault present in the Transformer. Natures of faults considered in this study are partial discharges, discharges of low energy, discharges of high energy, and thermal faults. Based on the dissolved gases present in the transformer oil several diagnostic methods such as Doernburg method, Roger's ratio method etc are commonly used for fault diagnosis. In some cases, all these methods are not able to diagnose the fault. Hence, there is a need to develop new methods. In this paper an Adaptive Neuro-Fuzzy inference system is applied for diagnosis of transformer faults.Keywords

This paper proposes a new QoS localized routing protocol for Guarantee reliability in Wireless sensor networks. The proposed protocol based on the QoS requirement according to the different data traffic types. The routing protocol is performed in three QoS metrics, namely Energy Efficiency, Reliability, and Latency. The Energy consumption is based on the residual, transmission and fusion energy cost. By using the data fusion technique the energy can be saved and thereby it increases the network life time for the sensor nodes. The tree data fusion structure gives high reliable packet transmission and also increases the packet delivery ratio. To estimate a latency and reliability model, by using a modular approach called WMEWMA (Window Mean Exponential Weighted Moving Average). In a large scale sensor networks the localized QoS routing protocol use the localized information which is desirable for Energy Efficiency, Reliability, and Latency. The simulation result demonstrates the data traffic types with the QoS requirements based on the data fusion technique and also provides high reliable packet transmission with high network lifetime.

Distillery spent wash contains nutrients and organic matter used in agriculture as a source of plant nutrients and irrigation water. Carbon and nitrogen play an important role in increasing the agricultural production. A laboratory incubation experiment was carried out to study the different concentrations of distillery spent wash on soil carbon and nitrogen dynamics. The treatments consisted of T1-Soil alone, T2-Spent wash @ 20 kilo L ha-1, T3- Spent wash @ 40 kilo L ha-1, T4-Spent wash @ 60 kilo L ha-1, T5-Spent wash @ 80 kilo L ha-1 and T6-Spent wash @ 100 kilo L ha-1. Among the different levels, the amounts of NH4-N, NO3-N and carbon were greater in soil that received 100 kilo L of spent wash compared to soil alone. Results shown that application of spent wash not only adds mineral N and carbon to soil, but also promotes the mineralization of soil organic C and N, thus resulting in large amounts of carbon, NH4-N and NO3-N in soil.Keywords

Face detection and recognition is the first step for many applications in various fields such as identification and is used as a key to enter into the various electronic devices, video surveillance, and human computer interface and image database management. This paper focuses on feature extraction in an image using Gabor filter and the extracted image feature vector is then given as an input to the neural network. The neural network is trained with the input data. The Gabor wavelet concentrates on the important components of the face including eye, mouth, nose, cheeks. The main requirement of this technique is the threshold, which gives privileged sensitivity. The threshold values are the feature vectors taken from the faces. These feature vectors are given into the feed forward neural network to train the network. Using the feed forward neural network as a classifier, the recognized and unrecognized faces are classified. This classifier attains a higher face deduction rate. By training more input vectors the system proves to be effective. The effectiveness of the proposed method is demonstrated by the experimental results.Keywords

Higher-order thinking, commonly known as higher order thinking skills (HOTS), is a concept of education reform based on the learning taxonomies such as Bloom's taxonomy. For various Bloom’s Taxonomy levels as Remembering, Understanding, Applying, Analysing, Evaluating and Creating, digital tools are available for students to develop those levels of skills. However, it requires that for each subject area in the engineering education, the faculty members have to identify the specific thinking skills as applicable for the subject and need of the student. Then they have to design the activities and projects with the necessary specific tools.
In view of the above, a group of faculty members in our institution took up a case study on Computer Architecture and Organization and identified the thinking skills to be developed. Based on this, they designed a set of activities and projects with the necessary tools as specific to the subject. It is required to use the generic digital tools.
