These lesions are generally complex in nature and exhibit heterogeneity in their intensity profile and morphological properties. To address these challenges, a novel segmentation algorithm using Symmetric Bit Plane Pattern analysis is presented in this work.

Abstract: The growth of any country depends on the availability, accessibility and affordability of electricity to all connected consumers; hence the electricity is the key for any developed country.
To make electricity affordable and available to all consumers, many countries started implementing time based pricing to interested consumers. In India, energy tariff is slab wise for the residential load.
Micromachined Resonators: A Review
The philosophy behind this slab wise tariff is to facilitate or reward low energy users and charge extra for high energy users. But in that case, the middle class group of society has no encouragement for optimal utilization of electricity. Therefore, in such circumstances the real time tariff is very much needed for residential consumers also. They have found that real time tariff is superior than slab wise tariff. In India, it has been a concern for economically poor class. A policy can be made for consumers below the poverty line or low income group; for them slab wise tariff will be continuing and for rest others, a provision of real time tariff can be made.
Hence in this work proposing real time tariff for residential consumers in India. The existing tariff structure for India and other countries is discussed in this work and proposing the solution for the Indian residential sector. Abstract: The aquaponic systems are the combination of fish and plant culture. These are recirculating systems with two components: hydroponics and aquaculture. In these systems, the food given to fish is metabolized.
This metabolized food fulfills the nutrient requirement of plants. This is achieved by the recirculation of water from the aquaculture component to the hydroponic component and back to the aquaculture component. This experiment is conducted to test the effect of recycling of water in a longer period on the growth of iridescent shark and balsam plant in the aquaponic system. The system developed is 1. In the hydroponic component course aggregate of 0. Coconut husk and sand particle layers of 0. An average quantity of 1 kg of balsam plant leaves was produced in 60 days of plant growth.
It has been found that balsam plant and iridescent shark species in this system has a faster and better growth compared to the conventional growth. The water used in the system is completely replaced once in three months after 45 days. Also, it was recirculated once in 3 days during experimentation. The DO level of fish tank water was dropped below 2 ppm during the span of two successive recirculations. No direct sunlight was available for the plants and no other artificial light source was used in cloudy and humid atmospheric conditions.
The experiment also tested the success of the aquaponic system in adverse conditions like unavailability of fresh water for replacement, poor sunlight and minimum DO condition. The combination of balsam and iridescent shark proved to be suitable for the aquaponic system under such adverse conditions.

Keywords: Cloud, Cryptography, Objective function, Homomorphic. Neural network which can learn from experience are becoming popular in solving many of real worlds NP-hard problems. Today any prediction application is taking the support of Neural Network. The accuracy of the neural network models depends on major of the design components like the hidden layers and the activation functions.
As we know human brain receives both relevant and irrelevant information at a time and has the capability of segregating both, where the irrelevant can be referred as noise. Just like the human brain the neurons uses activation function to separate the noise from the input and reduce the error. This paper presents the role of hidden layers and activation functions in measuring the accuracy of the Neural Network. Abstract: Wireless Sensor Networks transmit data from source to destination and inform base station using various sensors.
However, the routing path through multiple hops of WSNs usually becomes the target of severe attacks. Outmoded cryptographic security techniques have proven to be inefficient against several insider attacks such as wormhole attack, sinkhole attack, Sybil attack, selective forwarding attack, etc. These attacks further impacts on restating of routing information and also exacerbate identity deception. To handle such instances, trust aware routing can be the alternative to provide a trustworthiness and energy efficient route irrespective of known geographic information or tight time synchronization.
Significantly, it is strong against the attacks caused due to identity theft. Besides that WSNs are also vulnerable to the attacks illegally acquiring network resources which is caused by many popular attacks. These attacks are complex as it affect not only the victim but its legitimate members also.
Existing routing techniques could not solve these severe issues. The proposed scheme demonstrated an average throughput of 6. Abstract: The article is devoted to the discussion of the recent trends and reformation of housing and communal services in Uzbekistan introducing ICT to the sphere. The object of the research is the sector of housing and communal services of the Republic of Uzbekistan. The actuality of the research consists of increasing number of scholars of several developing countries who are interested in how to use the ICT and by this to achieve economic effectiveness both in the scope of country and company.
For example, regardless of the reformations and development in this sphere, a row of problems is unsolved. Nowadays population is not satisfied with the supply of communal services; hence the number of complaints on the work of service providers is increasing. In addition, the problems of expenses and debts above normal and not correctly calculated are remain open.

Abstract: Water is the most essential and foremost constituent for all the organisms living in the earth.
Sometimes it would be the major reason for the demolishment of lives when the needed level is increased. This resource is available through low, moderate and high level rainfall and it is preserved in various places for future usages. In this paper we discuss about the disaster caused by water stored in dam. When the storage level of the dam is increased, it is expelled or released without any alarm as a result it squashes many of the lives. Our main focus is to issue alarms before releasing the water from dam.
We use an unmanned method using wireless sensor technique to monitor the water level continuously, if it reaches the saturation point extreme storage level , we propose 3 alarming facilities, as 1. Sending message to the people located in the area, 2. Provide audio alarm which is battery enabled 3. Make drone alarming UAV to all the people. After the alarming process is done the shutters of the dam is released to expel the water.
Keywords: Dam monitoring, Drones, Shutters, Unmanned. Abstract: The quality of fingerprint or fingerprint verification depends on the quality of the fingerprint image.

Fingerprint, Image segmentation. Abstract: Nowadays, all electronic gadgets and devices are in the race of most compact size and least power consumption.
Along with it, we want device to do many jobs at a time. For that it needs to be laced with maximum computing power. In CMP architectures, parallel task execution is done rather than executing task sequentially, as it is done in conventional programming. However, NoC consumes significant percentage of total power. Final objective is to design power efficient NoC. In CMP architecture, many data transfers are done simultaneously. It is required to evolve power saver NOC with unique task scheduling schemes. Our approach enhances network latency, network throughput along with energy reduction.
It defines performance of the system with high speed transmission. It shows improvement in the system performance when experimented with various applications. Here, we concentrated on proper distribution of tasks and network traffic required for execution. One needs to balance between over and under utilization of resources. Analysis of both the cases is done in this article.
Over utilization is injecting excess traffic in the network which leads to heat up problem. Under utilization is, PEs remaining idle for long time resulting in sluggish performance. Here we tried to list various innovative methods for saving network from reaching power wall. Energy modeling and granular traffic analysis gives us accurate estimation of device performance beforehand. Also, analysis is done for various topologies for different tasks. Abstract: MANET networks often form with mobile devices to enable communication and connectivity in time-critical applications.

The proposed routing protocol simulate in the NS2 environment to evaluate network performance of flood-based routing algorithm. Abstract: In this paper, a case of prediction of sample demands for industrial lubricants has been presented. We have observed that the demand for most of the industrial lubricants depends on three main factors i. These factors are studied and compared with other competitors dealing in similar nature of products. The quality is mapped with three fuzzy parameters viz.
The cost is linked with three linguistic variables viz. Similarly, delivery time is also associated with three sub-parameters viz. First, the raw data of demand for 12 number of random samples are collected from supply chain executives of an automotive and industrial lubricant manufacturing company. Thereafter, the membership functions for the causal factors and demand are built on the basis of comparative analysis and collected data. At last, a fuzzy- inference demand model with rule base is constructed.
Finally, the demands are predicted by the skilled fuzzy model. Predicted data is compared with the raw data and absolute errors are being calculated. The result shows predictions made by the fuzzy-inference demand model are in tune with the actual demands of industrial lubricants. Thus, the built fuzzy model can be utilized and generalized for effective demand forecasting for industrial products.
Abstract: Passive tracking of a target using bearings-only measurement which is carried out in underwater scenario is most widely used. This paper considers the problem of estimating the position and velocity of a target in an underwater scenario. The noise in measurement is more as underwater scenario is considered which leads to less accurate estimation.
Particle filter PF which is a non-linear filter is considered for this problem. In PF, all particles are assigned with weights based on their likelihood computed with respect to obtained measurements. The weights assigned to the particles, after certain time period tend to equal values called sample impoverishment.
The main difficulty using PF is sample degeneracy and sample impoverishment. Evaluation of the algorithm is assessed based on the best convergence time of the solution for many scenarios using MATLAB software. Abstract: Net Asset value NAV prediction is considered as a financial time series forecasting problem. Different linear and nonlinear time series forecasting models have been used in NAV prediction by various researchers. The individual models are trained with conventional LMS algorithm. It is a weighted linear ensemble model where the weights are optimized using a modified Whale Optimization Algorithm.
The empiricalforecasting performance of the modified Whale Optimization Algorithm based ensemble model along with GA and PSO based ensemble models and the individual models are analyzed. The results demonstrate that the proposed ensemble model outperforms the other models. The principle of separating control plane and data plane has opened up many opportunities for researchers to deploy new innovations.

Luis M. Research Topics in Electrical Eng. It will teach, at the level of IIT graduate students, an understanding of the principles, analysis and design of Permanent Magnet Motors. At the end of the subject a student will have the capability of designing and constructing a suitable PM Motor for his chosen application. In addition to design, students will also learn how to estimate the dynamic parameters of PM Machines and understand what the implications of those parameters are on performance of systems incorporating those machines.
Examples taken from current research include some set of: 1. Inner rotor PM Synchronous Motors such as the machines that are used for traction drive of an electric vehicle. Since we are attempting to use such machines in our research into 3 wheeler propulsion, we will spend a little effort at trying to figure out how to optimally control them.
If time permits, we might consider some other applications such as "white goods" like washing machines, refrigerators, air conditioners etc. We assume that the students are smart and self-motivated, require little hand-holding and know when to seek help. Heavy emphasis will be placed on the assignments, with a mix of problems from textbooks and others suggested by current research. There will alsobe two quizzes and a three-hour final exam.
Completing the problem sets will be the most important way of learning the material. The problem sets will require some heavy lifting and one may want to have a program to help out.
