Abstract

ES is considered a breakthrough technique to integrated performance management and EVM theory and practice. Earned Schedule (ES) is a method of extracting schedule information from Earned Value Management (EVM) data. The method has been shown to provide reliable schedule indicators and predictors for both early and late finish projects. ES provides time based measure of schedule variance (SV(t)) and Schedule Performance Index SPI(t) metrics with behavior analogous to the EVM cost based counterparts. Traditional Earned Value Management (EVM) index-based methods for Cost Estimate at Completion (CEAC) of an ongoing project have been known for their limitations inherent with both the assumption that past EVM data is the best available information and early-stage unreliability. In an attempt to overcome such limitations, a new CEAC methodology is proposed based on a modified index-based formula predicting expected cost for the remaining work. The proposed model shows itself to be more accurate and precise in all early, middle, and late stage estimates than EVM.

Abstract

Rapid urbanization, Environmental pollution and depletion of natural resources etc., pose great challenges for the cities all over the world. And some of the cities had already taken some tangible steps towards forming a special type of city called smart city. As a structure for urban transformation, smart city initiatives targets to connect the information and communication Technology and knowledge infrastructures for economic growth, Social unity, efficient city administration and Resource management. Earlier smart city initiative revealed several technical, social, economical, managerial and governance challenges arising due the complexity of smart city because it is a system of multiple systems. There is no precise developed framework of smart city initiatives available for to guide policymakers, practitioners, and other smart city stakeholders. In response to this need, my work presents a "Smart City Initiative Design Framework" resulted from the analysis of major smart cities programs like Seoul, Amsterdam etc,. The findings provide a design platform for the objectives, outcomes, implementation options, strategies, and the enabling different agencies in public and private Sectors for Smart city initiatives. The main objective of this study is to make the concept of smart cities easier to understand. My present work also discusses challenges in adopting smart city concepts and their sustainability in Indian conditions and proposes some effective and practical solution to build smart cities for a smart urban living.

Abstract

In spite of substantial improvements in material strength and increased accuracy in analysis in Design and Analysis with the aid of digital computers, gradual detoriation of structures during prolonged usage cannot be completely ruled out. This has been proven by many recent accidents such as sudden Bridge Collapses and in-flight break downs of Aircrafts and shuttles, causing immense loss in lives and properties. Hence, the idea of equipping structures with sensors and actuators in an attempt to impart "smartness" has great potential in cost-effective predictive maintenance of structures, particularly for high performance components not easily accessible for manual inspections. There is a huge demand in finding out a new method of SHM in Civil Engineering Structures, which should be a feasible, low cost, light weight and appropriate method to predict the damage in advance to save the Lives and property. In this report, the importance of Smart materials, especially Piezoelectric materials in Various Applications in field of Engineering have been discussed. SHM principle and case studies related to SHM have been discussed. Electro-mechanical Impedance method and their applications in SHM of Civil Structures is explained along with a Case study of Utilization of Piezoelectric material in RC Structures in SHM applications have been discussed along with the discussion of results.
