Labour Productivity Model for Structural Elements by Varying Build ability Factors using Multiple Regression Analysis

Construction productivity is one of the most frequently researched topics due to its importance to the viability of the industry. Buildability is defined as the extent to which the design of a building facilitates ease of construction, subject to the overall requirements for the completed building. In this project, the major buildability factors hypothesised to influence the labour productivity of the main trades, i.e. formwork, reinforcing steel fixing and concreting, included grid patterns of footings and columns, type of structural framing system, geometry and dimensions of elements, height of floors, the degree of design rationalisation, standardisation and repetition of elements, reinforcing steel quantity and diameters, location and congestion of reinforcement, volume and workability of concrete as well as surface finish. In addition, and due to its importance to the productivity of the construction industry, the effect of the learning curve theory has been also examined in this study. This research project has quantified the relationship between the principal design characteristics of in situ reinforced concrete construction and labour productivity of the various trades involved. It can provide practical guidance to architects and structural designers who seek to optimise their designs. In addition, it can give a feedback on how well the designed building considers the requirements of the basic buildability principles and provides for tangible consequences of their design decisions on the construction labour productivity.

Knuckle Finger Imager for Identification using Accurate Person Matching Score

A biometric system using finger knuckle patterns has recently drawn the interest of researchers worldwide. Compared with its hand counterparts, palm and knuckle parts has several unique merits. Knuckle print based biometric system is highly acceptable because these patterns do not disturb with injury and wound on the finger surface. However, geometrical and textural features have been used widely in most of the existing knuckle print recognition methods where an individual is verified by extraction of size, length, position and shape features. This paper presents a matching score scheme for personal recognition using novel inner knuckle print-based features i.e., knuckle distance based geometrical features, and texture features. The proposed method is tested on our in-house Hand database (720 images) collected over a span of 3 months. Finally, the test and training images are compared in terms of using fusion and decision algorithm.

Case Study

Power and Energy Management of a Household Photovoltaic-Wind System with Battery Storage

With the expanding power request and the persistently creating of sustainable power source advancements, battery energy storage systems (BESS) appear to be a critical piece of a keen network, giving numerous advantages, for example, lessening the power charge, diminishment of pinnacle request and taking care of the age with the demand side. In this investigation, a battery execution display is proposed for a private home with conveyed age from inexhaustible assets. Genuine irradiance and wind speed information estimated in two unique times of the year (i.e. summer and winter) have been utilized and mimicked for 24 hours. Battery stockpiling is an appropriate arrangement because of the quick reaction and adaptability. Incorporated with a smoothing usefulness, it can charge and release to lessen the power vacillations created by PV boards and wind turbine. Reproductions demonstrate that the picked moving normal calculation does not require a major battery measure, conveying acceptable outcomes even with a littler battery. Further, considering the request energy of the house and the created control, a normal power bend is processed at regular intervals keeping in mind the end goal to be traded with the utility framework and limit the power charge.

Land use Analysis on Urban Sustainability in a Transit Oriented Development

Urban sustainability involves environmental, economic, social and political issues. The challenges in urbanization such as population growth, urban sprawl, poverty, inequality, pollution, congestion, and mobility need to be addressed to achieve a sustainable, livable, economical and energy efficient urban form. This paper aims to highlight the urban sustainability issues that arise due to the rapid development of transit corridors by analyzing the changes in land use structure and urban form in relation to a transit-oriented development.

FPGA – Based Electro Cardio Graphy Signal Analysis System using Least Square Linear Phase Finite Impulse Response Filter

Proposed design for analyzing electrocardiography (ECG) signals. This methodology employs high pass least-square linear phase finite impulse response (FIR) filtering technique to filter out the baseline wander noise embedded in the input ECG signal to the system. Discrete wavelet transform (DWT) was utilized as a feature extraction methodology to extract the reduced feature set from the input ECG signal. The design uses back propagation neural network classifier to classify the input ECG signal. The system is simulation on xilinx system generator.

Integrated Redevelopment of Foreshore Estate and Srinivasapuram

In Chennai there are constraints on the availability of unused land within the city limits, coupled with fast growing demand for built spaces and sky rocketing prices. On the other hand, that there are thousands of aging buildings which are dilapidated and under used blighted urban areas which have reached a stage where it is not possible to carry out structural repairs and rehabilitation as the same are not economically viable. Therefore, redevelopment has become a necessity as in time these areas become more dangerous and unfit for habitation. One such potential project is the Integrated Redevelopment of Foreshore Estate, where a large land parcel available for re-development, right on the shoreline. Foreshore Estate is an ideal location from where one could easily reach the most sought-after locations like Adyar(which is a large residential neighborhood in south Chennai with very high property values), Besant Nagar, R A Puram, Alwarpet and Mylapore(it is a cultural hub and neighborhood in the southern art of the city of Chennai .it is also known for its tree-lined avenue), MRC Nagar ( it is a commercial hub of the city which also include residential areas), as well as the best of the hotels in the city, besides critical facilities like the airport, sea port and railway station within 10 to 30 minutes. The idea is to develop a mix of high-end residential units, a fair amount of commercial space and also allot sufficient space for development of low-cost housing units, as the re-settlement of earlier tenements also has to be addressed. Tamilnadu Slum Clearance Board (TNSCB) and Tamilnadu Housing Board (TNHB) together hold 51.01 acres of land (23.5 and 27.51 acres respectively) in Srinivasapuram and Foreshore Estate area, facing the Marina Beach. Projected as the “Integrated Development in Foreshore Estate” the scheme envisions malls, luxury hotels and high-end residential complexes for private parties and senior Government officials and resettling the 3576 slums and 2000 housing board tenements.
