Abstract: Automatic image segmentation requires a certain degree of depth of work combining image clustering, feature extraction, statistical analysis and iterative feedback. Researchers have been using algorithms like Principal component analysis (PCA) combined with advanced feature extraction techniques like gray level co-occurrence integrated algorithm (GLCIA), along with maximal difference schemes (MDS), have been proposed by researchers, and provide good quality of semi-automatic segmentation. But in these techniques, user intervention is needed in at least 1 of the steps in order to get a proper output. This work proposes a RP-live wire based algorithm which optimizes the segmentation process, and removes the user intervention from the segmentation process in order to produce high quality segmented images with truly automatic segmentation. Our results demonstrate a 20% improvement in overall system speed and 10% improvement in segmentation accuracy when compared with traditional algorithms.

Abstract: Designing two degree of freedom controller to control the boost chopper system is challenging. A new feedforward combined with feedback controller design is proposed. Increasing the efficiency of the DC-DC converters can be achieved by decreasing the distortion and noise for both input and output stages in the system. A linearization mathematical model analysis for boost chopper is presented. Both the input voltage with multiple steps and the duty cycle of PWM which control the switching circuit were applied to study the behaviour of the system. In this study, the simulation results show that the disturbance rejection and input tracking were improved for different cases and situations. Also, the results show that the proposed method can be adapted by redesigning the feedforward controller to recover the impact of the boost parameter changes.

Abstract: The present study has as principal objective to simulate the control of sub-actuated robotic hand, using resistive sensors capable of interpreting finger movements and converting them into electrical signals, sending them to a central controller. This research aims to develop a biomechanical prototype capable of efficiently controlling devices and equipment at a distance, applying theoretical concepts of the Mechatronic. This situation is discussed because of the difficulty of accurately replicating the movements with the highest degree of mimicry of the human hand, in order to get as close to reality, generating the need to use a more complex architecture and with a high cost. Initially, only the control of the signals emitted to the microcontroller will be analyzed, in order to classify them in a scale and, later, to execute specific movements of the motors. Several tests were carried out..............

Abstract: This paper describes the system which was designed and a developed prototype to clean off the dust from a PV module. Dust settlement on the PV module surface is one of the factors affecting the performance of PV module by obstructing solar irradiation incident on the module surface. By cleaning off the dust from muddle surface therefore improves the module output and ultimately improving even the overall performance of the PV system. The results show that with the system was able to respond to the low output level by wiping the surface of the PV module. The prototype assembly comprise of a programmed Arduino micro controller, a PV panel, wipers, battery and motors and artificial light simulating the sun. Further work will focus on developing real system since the prototype has proven that the system is viable. The work is still ongoing whereby a prototype will be built to demonstrate the practicality of the system.

Abstract: Solar power is a clean and sustainable energy as it is pollution free and environment friendly. This energy can be stored as thermal energy using latent heat storage system. The storage material used in our work is paraffin wax that stores the heat as latent heat. Phase change materials (PCMs) are preferred because latent heat storage is more efficient than sensible heat storage. This paper presents a key idea to minimize the energy shortcomings in Pakistan using renewable energy and thermal storage system. In order to increase the thermal conductivity several types of fin arrangement are being studied and it is found that cross fins arrangement gives the maximum output in terms of thermal conductivity. Keeping in view a new longitudinal (120˚ apart) fin arrangement is made and tested. Experimental results verify that our fin arrangement exhibits much better results than the cross fin arrangements.

Abstract: Grid is framed as a planned nationwide network that makes use of information so as to deliver electricity in an efficient, reliable and secure manner. This entire electrical system is very difficult to monitor because any rise or fall of electrical impulses, in this system may result in the damage of highly expensive electrical components, as a result causes failure to an entire system. Therefore, there is dire need of controlling such damage of these synchronous machines and other component appliances so that these failures are avoided, which may result in loss of life and property. We have used various data mining approaches on a SCADA dataset which has been derived from solar electric power plant and is being monitored by grid station. The data pertains to the real time values pertaining to voltage and current. The proposed research uses this real time data for constructing a probabilistic model to respond to the above problem in a very intelligent manner.

Abstract: This paper describes building up of a model for computing the load forecasts as well as producing load profiles of a selected village and comparing it with national load profile. The main requirement before developing the models were ease of interphase (graphical user interphase) and accuracy of load profiles and forecast. The user-friendliness of the model is its ability to access, import and analyze historical data of the location whose load profile or load forecasting is to be determined. Selection and calibration of the model through the use of neural analysis tool has also been employed by the model parameters calibration and validation. The model has been built and successfully demonstrated. It produced load profiles and some forecasting performed, as shown in the result section, of selected village. The total load profile for villages does not necessarily follow a similar pattern to the national load profile due to socio economic activities, lifestyle patterns and extent of industrialization or commercialization of the village. This work is an extension of the work by the same authors who had worked on approximate mathematical model for load profiling and demand forecasting.

Abstract: The aim of this study is to develop a strategy based security applications to improve the software
security defined network using modern proficient algorithm. It has a control model by the separation of the
control plane and data plane. It's well suited to secure the network deployments and provides logically
centralized intelligence programmability. But, the software defined network suffers from denial of service
attacks in most cases. To overcome this crisis, security algorithm has been proposed to protect the network and
investigated the security assets on the software defined network control channel and required algorithm to
overcome the security problem. Hill cipher algorithm is used for providing authentication to secure the software
defined network. This analysis is focused on performance of various routing protocols running over software
defined network by using the authentication mechanism. Performance metrics like throughput, end-to-end delay
and packet delivery ratio were considered for analysis. The result shows that the destination sequenced distance
vector routing protocol have better performance in software defined network.

Abstract: This paper gives the thermal investigation of fire-tube boilers utilized in thermal force plants. For
reproduction reason, a little scope model of the first fire-tube evaporator is planned utilizing Solid Works. The
numerical reproduction of the structured model is completed in ANSYS Fluent. The underlying area of the paper
speaks to the weight and temperature varieties along the length of the kettle for various water speeds (25 m/s, 30
m/s, 35 m/s and 40 m/s). The later segment bargains by changing the evaporator packaging material between
steel, metal and treated steel to consider the weight and temperature varieties at consistent water speed of 30
m/s. In light of the outcomes, the best kettle shell material among these three has been recognized. The outcomes
have been given as weight and temperature shapes as got from the CFD investigation.

Abstract: Data sharing with a huge numeral of accomplices requisite take into account a number of concerns,
including data owner's efficiency, data integrity and privacy. Ring signature is an auspicious candidate to build
an unspecified and trustworthy data sharing system. It endures a data owner to anonymously endorse data
which can be positioned into the cloud for storage or analysis determination. The exorbitant certificate
verification in the traditional public key infrastructure (PKI) setting suits a blockage for this elucidation to be
ascendable. Identity-based (ID-based) ring signature, which eradicates the process of certificate verification,
can be used instead. Data sharing has certainly not been tranquil with the progresses of cloud computing, and a
precise analysis on the shared data runs an array of assistances to both the society and individuals. In this
Improving efficiency, data integrity and Effective privacy policy and Anonymous Data Sharing with Forward
Security, it is additionally enriched the security of ID-based ring signature by providing forward security
