Carbon fiber reinforced polymers (CFRPs) are one the stiffest and lightest composite materials, they are much convincing than other conventional materials in many fields and applications. Use of composites is limited due to their higher rice and lower formability. Use of nanoparticles increases mechanical properties of these composites. As these composites are costly materials, Non Non-destructive testing (NDT) such as Eddy current pulsed thermography (ECPT) is used for studying properties against impact loading. Modifying composite papers with Hot Melting Fibers (HMF) shows increase in mechanical properties without considerable reduction in electrical properties.

Pages: 244 - 250
A wireless sensor network (WSN) comprises of thousands of sensor nodes dispersed over a topographical zone. An essential issue of WSNs is to decrease their energy utilization keeping in mind the end goal to improve their life time. Low energy is more essential contrasted with low power for such networks as it will expand lifetime of the network. Thus, minimizing energy utilization turns into the most basic issue in the outline of all WSN protocol. For end-to-end information transmission, media access control (MAC) and routing protocol involved as a vital part in WSNs. In addition, this protocol for the most part uses the hierarchical structure for end-to-end reliable information conveyance. The time and energy required to create a hierarchical structure in a successive way is constantly high. Thus, with a specific end goal to reach the above challenges in such networks, the majority of the energy is devoured when the radios are on, sitting tight for an arrival to happen. Sleep-wake scheduling algorithm is a best method to increase the lifetime of these energy obliged wireless sensor systems. In the proposed methodology I will use suitable algorithm that is parameter based reliable routing(PBRR) for efficient route selection and blowfish algorithm to secure the data furthermore diminishing energy utilization By utilizing above strategies, proposed results ensures in the decreasing of Energy Consumption, Higher the network lifetime, reducing the average delay, and High packet delivery ratio.

This paper describes about the smart technology which is the need of this hour to make the hospitals smart. All kinds of patients need monitoring and immediate attention in times of emergency as well as daily needs and among those the bedridden patients are the most dependent ones. So the project aims at easing their lives by providing assistance to the patients with absolutely no delay. By just making a few tilts on the android devices, the patient gets the required assistance which avoids complexities and makes the hospital to function smoothly and well co- ordinated.

Time overruns has been a noteworthy issue in numerous Indian construction projects. The successful execution of construction activities and keeping them within recommended plan and cost is imperative for compelling time execution and cost execution. This thesis work is done on concentrating on noteworthy factors creating Time overruns in Indian construction industry. A valid questionnaire for the overview was produced taking into account factors for time overruns recognized from writing survey. These factors are assembled into 9 groups for time overruns and disseminated among three parts in particular Real Estate, Infrastructure and Industrial of Indian Construction Industry. The information from the survey was broke down measurably. Relative vital list system was utilized to establish out the most noteworthy variables influencing Time overruns. The result accomplished from the survey revealed that the major cause for time overruns are Clearances on Delay, Drawing Revision and Clearances from Consultant/Client/PMC, Incompetency of Labour, Unrealistic Planning and not using Monitoring and controlling Tools & Technologies, lack of Leadership qualities in Managers, Procurement Planning and Procurement Process. The study discoveries highlight the noteworthy factors and a few recommendations are given to control time overruns in Indian Construction Industry.

A most recent system to handle the twofold talk (DT) inconvenience in acoustic reverberation cancelation (AEC). it is construct absolutely with respect to a recurrence range versatile get out (FDAF) execution of the so-alluded to as expectation errors technique versatile separating the use of column operations (PEM-AFROW) essential to the FDAF-PEM-AFROW set of controls. We show that FDAF-PEM-AFROW is through creation identified with the exceptional straight impartial assessment (BLUE) of the reverberation course. We withdraw from this structure to uncover advancement in regular general execution concerning uncommon versatile channels minimizing the BLUE model, specifically the PEM-AFROW and the FDAF-NLMS with near stop sign standardization. The determination of FDAF-PEM-AFROW over PEM-AFROW and FDAF-NLMS with close surrender sign standardization, construct absolutely for the most part in light of general execution, computational many-sided quality and related IPC measure values. Then simulated in Matlab.

Pages: 277 - 281
Distributed database systems use commit protocols to ensure atomicity in case of distributed transactions and a wide variety of commit protocols have been proposed so far. Two–phase commit (2PC) is a widely accepted standard protocol for distributed transactions. But 2PC suffer from blocking problem due to which three-phase commit (3PC) protocol was proposed which is an extension of 2PC. This paper present a review and comparison of commit protocols used for distributed database systems.

Building Information Modeling (BIM) is a process involving the generation and management of digital representations of physical and functional characteristics of Projects. This study work is intended to understand the links between BIM and energy analysis tool for renovation project. To achieve this goal; to reduce the energy use and carbon emissions from buildings, there is a need to efficiently renovate the existing building facilities to improve energy performance. Building Information Modeling (BIM) assists architectural assess different alternatives at the renovation stage of a building life so that effective energy strategies are attained within the building constraints. However, for the retrofitting work, there is a need for a proper and systematic methodology to monitor the behaviour of buildings and to make critical decisions to ensure that the energy criteria of the design are really met in practice. This study introduces a conceptual BIM-based model that can improve the energy and meet the requirements for high rise residential buildings.

Carbonation is one of the major reasons for the decrease in pH of cover concrete. This reduction in turn will lead to the deterioration of the passivizing layer around the steel bar and opens a way for the corrosion to occur. Several factors that are controlling carbonation includes: Relative humidity, Temperature and Carbon dioxide percentage. Various researches have been carried out on carbonation study. This paper reviews the experimental and theoretical studies on carbonation in concrete.

A Wavelet based ICA Algorithm for Separation of linearly mixed Speech Signals
Mohit Kumar ; Asst. Prof Saranjeet
Electronics & Communication Engineering
Year: 2016, Volume:2, Issue : 12
Pages: 292 - 296
In this paper, an algorithm is purposed which can be used for separation of linearly mixed speech signals. Initially, this task was done by a popular algorithm called Independent Component Analysis (ICA). ICA is an effective algorithm to decompose mixed in to independent components. But it is observed that, when number of independent speaker increases, ICA is not able to extract the independent components completely. Hence the performance of ICA is satisfactory only when two individual speakers are present. The problem of extracting three speech signals more accurately is solved by using a Discrete Wavelet Transform based ICA. As a result of wavelet decomposition, wide band signals are converted into narrow band which decreases the probability of finding two independent signals in same frequency band. Recorded signals by the microphones are fed to an analysis filter bank which decomposes the signals in to approximation and detail frequency bands. These two groups of signals are further processed by ICA separately and then combined by synthesis filter bank to get the independent source signals. Further statistical parameters of the DWT based ICA are compared with conventional ICA on the basis of their performance.
