Abstract:

In order to study different powder/asphalt ratios effect on nonlinear viscoelastic responses of mortar, this paper choose limestone as the filler, and powder/asphalt ratio is 0.2,0.4,0.6,and 0.8.The tests were conducted using a Dynamic Shear Rheometer to perform multiple stress creep recovery (MSCR) tests.The test results show that􀉼with the increase of powder/asphalt ratio􀉼irrecoverable creep compliance(Jnr) value of the mortar decrease gradually, and the amplitude is larger.High temperature performance of the mortar are improve obviously.Using environmental scanning electron microscopy to scan those mortars,it analyzed the improvement of mortar from the microcosmic mechanism.

  [Abstract] [PDF] [Cite]

Abstract:

The project is based on mobile wireless robot technology that performs the dual operation as obstacle avoidance and fire extinguish. The sensors used here are ultrasonic sensor for obstacle avoidance and flame sensor to detect the fire. Here, the signals are received by an Arduino board for controlling the robot. The motor drives are used to drive the robot. A wireless monitoring system is used to display the present scenario.in detail It is a robot that autonomously detects and extinguish fire. It uses flame sensor for detection of fire, also ultrasonic sensor to detect obstacles and Arduino board for processing. The Fire extinguisher along with actuator is used to extinguishing the fire which is been detected. The robot continuously scans for fire. This scanning is performed by Flame sensors placed on the sides When a fire is detected, it moves in the direction of fire and stops in front of it and trigger the extinguisher to turn out the fire.In order to achieve the extinguish process a robot has arm with Electronic valve and a motor is used along with the body to change the angle of the arm. This arm and motor can be controlled by the Arduino. The power source for the robot comes from a battery.
Key words:Robotics,Arduino, Obstacle Avoidance, ultrasonic sensor, Flame sensor.

  Phablo Ramos Carvalho, José Flávio Silveira Feiteira, Alberto Paiva
  [Abstract] [PDF] [Cite]

Abstract:

"The Chimera State could be a result of the interaction between the resonant frequency and the synchronization process in a network of identical oscillators. The target of this paper is to do the numerically investigation of the chimera occurrence in a model with fifteen metronomes on each swing and two coupled swings Therefore, changing the value of metronomes oscillation frequency one can observe the level of synchronization between the two populations of metronomes through the Kuramoto complex order parameter. This analysis was conducted considering three different values of the connecting spring's stiffness among the swings. Thus, a relation between the presence of chimera state and the system resonant frequency was observed.

  [Abstract] [PDF] [Cite]

Abstract:

The growth of the software development industry approaches the new development methodologies to deliver the error free software to its end-user fulfilling the business values to product. The growth of tools and technology has brought the automation in the development and software testing process, it has also increased the demand of the fast testing and delivery of the software to end customers. Traditional software development methodologies to trending agile software development trend have brought new philosophy, dimensions, and processes having invested new tools to make process easy. The Agile development (Scrum, XP, FDD, BDD, ATDD, ASD, DSDM, Kanban, Crystal and Lean) process also faces the software testing model crises because of the fast development of life cycles, fast delivery to end users without having appropriate test metrics which make the software testing process slow as well as increase the risk. The analysis of the testing metrics in the software testing process and setting the right lean test metrics help to improve the software quality effectively in agile process.

• Electronic Hand Glove Through Gestures For Verbally Challenged Persons
  Mukesh P. Mahajan, Devyani Badve, Pooja Sonar, Sayali Sonawane
  [Abstract] [PDF] [Cite]

Abstract:

This paper presents design of Electronic hand glove to facilitate an easy and better communication through synthesized speech for the verbally challenged peoples. Most Probably, a speechless person communicates through sign language which is not understood by the majority of people. The proposed system is designed to solve this problem. Gestures of fingers of a person of this glove will be converted into synthesized speech to convey an audible message to others. Speech is typically accompanied by manual gestures. Earlier there were many systems designed for dumb and deaf to interact with ordinary people. But these systems had many drawbacks and interrupts. We are designing such a system that even a dumb, deaf and blind can communicate with each other without taking help of ordinary people. This system is going to help them to interact with the outside world.

  [Abstract] [PDF] [Cite]

Abstract:

Mobile ad-hoc networks(MANET) are collected many number of nodes.In a mobile ad-hoc network(MANET) undertakes that all the mobile nodes unitewillingly in order to work accurately.This is a cost –intensive action for the collaboration and particular nodes can decline to cooperate then it will prominent to a selfish node behaviour.Thus, it will utterly affect the global network performance.The watchdogs are a well-known device used for identifying a selfish node.Theprocedure performed by watchdogs can fail,generating false positives and false negatives this may convince to wrong operation.Whenidentifying selfish node trusting on local watchdogs only can prime to poor performance,in terms of precision and speed.Thus we propose collaborative contact based watchdog(COCOWA) as a collaborative method based on the dispersion of selfish nodes responsiveness when a contact occurs,so the evidence will quickly circulated about selfish nodes. As shown in the paper,whenidentifying a selfish nodes this collaborative approach decreases the time and rises the precision.

• Effect of Grain Size and Reaction Time in Characterisation of Aggregates for Alkali Silica Reaction Using Chemical Method
  R.P. Pathak , Pankaj Sharma, Kachhal Prabhaakar , Sameer Vyas , N.V. Mahure , N Sivakumar
  [Abstract] [PDF] [Cite]

Abstract:

Concrete can deteriorate as a result of alkali aggregate reaction, an interaction between alkalis present in alkaline pore solution originating from the Portland cement and reactive minerals in certain types of aggregates. Potential reactivity of aggregates with regard to alkalis present in concrete mix can be determined by Mortar Bar method, Chemical Method and Petrographic analysis. Of these the chemical method though is quick and does not require a large quantity of material for testing yet have its own inherent limitations. It does not ensure completion of reaction as the observations are limited to 24hour only and also does not assess the effect of varying the combination of coarse and fine aggregates. A study on chemical method by allowing the reaction for a prolonged time up to 96 hours and also on different grain size ranged matrix was carried at Central Soil and Materials Research Station, New Delhi. Simultaneously the test results of the modified method are compared to the existing Mortar Bar method, Chemical Method and Petrographic analysis The outcome of the studies clearly reflects that the grain size play an important role in the reaction, the reaction time has a demarked impact on reactivity, in the cases having a high value of silica release the choice of reduction in alkalinity as an indicator of degree of reaction is not reliable, instead measuring remaining Na2O concentration in Sodium hydroxide solution after the reaction seems to be much more meaningful in justifying the silica release.
