<![CDATA[In information security the following security parameters like, integrity , non repudiation and confidentiality , authentication must be satisfied. To avoid thievery of organization resources it needs be secured in more efficient way and there is always demand for different levels of security attacks include virus , brute force and Eveadroper in business that organizations make use of voice biometrics an attractive low-cost. Voice biometrics is the cheapest among the other biometrics and used all levels for management to buy readily available metric and it is the way of identifying individuals remotely with high level of accuracy . In this work, we have been designed a new password- authentication approach that provides security using voice biometrics for authentication and uses the device itself into an authenticator which uses voice itself as its passwords and we are primarily interested in keys that can be temporally reproduced on the same device from the same user’s voice. Public and private keys are generated randomly from the user's voice and stored in the voice file(.wav).This Method uses voice recognition , include the operation of register( recording feature ) or voice prints and storing of one or more voice passwords into the database. It uses ECDSA to perform the authentication process that matching the voice sample with the database. The recognition, entity makes the database to decide that the sample is matched to perform an operation or not. Our proposed approach generates cryptographic keys from voice input itself and this algorithm developed an adhoc basis. It can effectively defend attacks specially brute force attack in system networks.]]>

<![CDATA[This paper discusses the modeling, simulation and optimization of integrated alternative source of energy system with grid substation. When there is a lack of energy in grid substation to meet the demand of customer load then alternative source of energy compensates energy deficiency and after that if there is excess energy available then remaining energy is stored in battery bank or sells to grid according to need. In another case when required energy is not generated by alternative sources then remaining energy is purchased from the grid and if the grid substation hasn’t available these remaining energy to meet the customer load demand during the peak load then stored battery energy is also active. The size of integrated alternative source of energy system may vary from few hundred watts to ten or hundreds of MW. The possible sources of alternative energy like solar, wind and biomass are considered under this paper. Study location, Muzaffarpur district of Bihar (India), is taken because there is good potential of energy generation from alternative source of energy and still there is no any wind and solar energy power plant. The modeling and simulation of the system is done by using HOMER software and the software solve the optimization problem to minimize the total cost of system and maximum utilization of alternative source of energy.]]>

<![CDATA[Shamir proposed the concept of the ID-based cryptosystem (IBC) in 1984. Instead of generating and publishing a public key for each user, the ID-based scheme permits each user to choose his name or network address as his public key. This is advantageous to public-key cryptosystems because the public-key verification is so easy and direct. In such a way, a large public key file is not required. Since new cryptographic schemes always face security challenges and many integer factorization problem and discrete logarithm based cryptographic systems have been deployed, therefore, the purpose of this paper is to design practical IBC using hybrid mode problems factoring and discrete logarithm. We consider the security against a conspiracy of some entities in the proposed system and show the possibility of establishing a more secure system.]]>

<![CDATA[This paper discusses technologies used to harvest energies from in-vivo environment. The discussion mainly concentrated on nanogenerators based on Piezoelectric nanowires which are employed for converting biomechanical energy (such as muscle stretching), vibration energy (such as heart rate sound, sound waves) and biohydraulic energy (such as blood flow, contraction of blood vessel) into electric energy. At the end this paper studies an approach for harvesting biomechanical and biochemical energies from living organisms simultaneously. This system, by using aligned nanowire arrays, can power medical nanosystems and nanodevices through converting vibration, biomechanical and biohydrulic energies into electricity. On the other hand by using biofuel cell structure, this hybrid cell can convert biochemical (glucose/O2) energy in biofluid into electricity. This technology can provide adequate power required for feeding nanodevices and nanosystems or at least to indirectly charge battery of the device. This technology can provide a sound basis for designing wireless self-powered nanodevices with direct energy harvesting from in-vivo environment.]]>

<![CDATA[The Direct current motors are in different types and there are several methods for controlling of their speed. In this paper two ways for speed controlling suggested. First a fuzzy logic speed controller for DC motor is designed and it’s parameter calculated by Particle Sward Optimization (PSO). The speed controller designed according to fuzzy rules, then for having better performance, the controller optimized with PSO. Secondly a PID controller that it’s parameter find by PSO, is used for speed controlling of a DC motor. At the end the performance of fuzzy logic controller compared with PID controller. The results show that fuzzy-PSO controller has better performance.]]>

<![CDATA[Turbulent forced convection of coolant air flow (10 m/s velocity) in a steel tube of 50 cm long having outside diameter of 60 mm and inside diameter of 30 mm with constant outside surface temperature of 1000, 1200 and 1400 Ko is numerically analyzed. The renormalization group k-ε model is used to simulate turbulence in ANSYS - FLUENT 14.5. An opened ring of rectangular cross section (5x7 mm) is fitted in the tube and separated by 8cm pitch. Results of temperature and velocity distribution along the tube center line for the case of tube with internal ribs were compared with that of plain tube , these results show that the use of internal ribs enhance the heat transfer rate and found to possess the highest performance factors for turbulent flow.]]>

<![CDATA[Fuel cell (FC) systems are appropriate candidates as alternative energy sources for use in stand-alone applications. Due to the typical power profile of a stand-alone consisting of transients is not suitable for the use of a sole FC system. This paper presents the control of the fuel cell for stand-alone application based on fuzzy PID (FPID) controller. The aim of the paper is to achieve the control of the fuel cell for stand-alone by designing a suitable power conditioning unit that consists of the two stages of DC/DC converter and DC/AC inverter. A PID controller to be used for the voltage control of the designed boost converter is proposed and compared with a classical PID controller for performance validation. Furthermore, an analysis of double loop fuzzy PID controller for a single phase inverter is done.]]>
