Title :: Optimization Methods to Develop Bounds for Reliability using Normal Distribution
Country :: India
Authors :: Sandeep Kumar
Page No. :: 01-07

In this paper, we proposed an alternative method to obtain the reliability of a system. This study deals with the analysis reliability bounds. Here, we consider that a life time of a system is normally distributed with prior normal distribution, the compound distribution is also a normal distribution. We developed a methodology to find the GLB and LUB for basic and updated basic distribution. The method enable us to determine the reliability and unreliability for each stage in the process of distribution development. Due to cost & time saving these reliability bounds are more useful than any other method.

Key words: Greatest Lower Bound, Least Upper Bound, Basic Distribution, Updated Distribution, Average Sample Number.

Country :: India
Authors :: K.L.Sudha || Om Prakash Singh || Pavan Mahalingappa Gunaki || Harshitha K || Sanju reddy
Page No. :: 16-21

Packet losses in computer networks are common phenomenon and are of great concern. Most of the existing methods used to overcome packet losses are time consuming due to the retransmission protocols involved. This paper proposes Luby Transform (LT) Code to overcome packet loss problem in computer networks and to get back the original message at the receiving end. Computer communication network is developed using Arduino and NRF Transceiver with which transmission and reception of data wirelessly is established between computers. The LT codes are effective in getting back the original information in spite of packet loss as it transmits modified packets which contain information about other packets also. The usability and reliability of the proposed LT code is verified by simulating the system in MATLAB and establishing the real time wireless communication system using Arduino and NRF Transceiver.

Title :: A Temperature Compensation Technique Based On Current Signal Reconstruction for Structural Health Monitoringusing Lamb Wave
Country :: China
Authors :: Jianzu Gu || Bin Zhang
Page No. :: 22-31

Lamb wave structural health monitoring technique is widely used in aerospace, civil andmechanical engineering. However, this technique is easily affected by environmental condition variations, especially temperature variations. This paper presents a temperature compensation method for Lamb wave structural health monitoring systems.The proposed method is based on reconstruction of current signal in different temperatures. To do this, firstly, a linear relationship between the time of fight (TOF) and temperature variations is defined after the linear reconstruction of phase spectrum of collected signals. Then, by using Hilbert transform,the amplitude and phase of selected Lamb wave are extracted.Subsequently, a Phase factor is introduced by calculating thephase difference between the current signal and baseline. An amplitude factor is also introducedbased on the mean square error (MSE) of the baseline and current signals...............

Ever thought how the life of a blind person, their life is full of risk. Theycan't even walk alone through a busy street or through a park. They shall needsome assistance from others. They are also curious about the beauty of theworld; they should have will be the excitement to explore the world, and to beaware of what is happing in front of them. Even though they can find their ownthings without anyone's need. So, there is an idea called SMART GLASSES.Simply, smart glass is a pair of glasses for the blind. By using smart glasses, aperson can able to know what is going on in front of him/her. Smart glasses isdeveloped with raspberry pi 3 and google android things. When the personpress the button on the smart glasses, the camera will take a picture andanalyse the image using tenser flow and detect what is that picture is about thenusing speaker or headphone, the google android will voice assist the personabout the picture.

Tire is a toroidal shaped inflatable envelop made up of an elastic material, natural or synthetic rubber as a blend, thereof, reinforced with textile or a ply fabric carcass enclosing bead rings.. Tire is the most important component of any vehicle and it establishes the only contact between the vehicle and the road. Without tire development, motor vehicle transport would not have been possible. It may be noted that more than 40% of word's rubber production finds its way into tires............

Title :: Voltage Control with Electric Springs
Country :: India
Authors :: Buchi Pavan Kumar || P Balanagu
Page No. :: 61-65

The concept of electric spring (ES) has been proposed recently as an effective means of distributed voltage control. The idea is to regulate the voltage across the critical (C) loads while allowing the noncritical (NC) impedance-type loads (e.g., water heaters) to vary their power consumption and thus contribute to demand-side response. In this paper, a comparison is made between distributed voltage control using ES against the traditional single point control with STATic COMpensator (STATCOM). For a given range of supply voltage variation, the total reactive capacity required for each option to produce the desired voltage regulation at the point of connection is compared..................

Keywords: Demand response, electric springs (ES), STATic Compensator (STATCOM), voltage control, voltage regulation.

Title :: A Comparative Study on Interference Factors of Buildings Depending Upon the Size of Control and Interfering Buildings
Country :: India
Authors :: Rishav Dutta || Shruti Sinhamahapatra || Sasankasekhar Mandal
Page No. :: 66-73

Wind forces and moments on each building in a row are measured with the base balance under different wind incidence angles and different separation distances between buildings. Many researchers have investigated shielding and interference, but each looked at a different small subset of large number of possible variables and configurations. There are many factors which govern interference factor including the size of the control as well as interfering building. The present paper looks into the change of interference factors depending upon the length-wise change in size of control as well as interfering building spaced at a particular distance from each other in a row.
