Mechanistic Approach for Fiber-Reinforced Flexible Pavements

Abstract: The present study investigates the benefits of reinforcing the subgrade soils in flexible pavements. Three types of Soils A, B, and C, and one type of polypropylene fiber having aspect ratios of 50, 84, and 100 were selected. The California bearing ratio CBR and unconfined compressive strength tests were conducted on unreinforced and reinforced soils. The optimum quantity of fibers was decided based on CBR, modulus of elasticity Ei and failure stress. The static triaxial tests were conducted on unreinforced and reinforced soils as well as on other pavement layers at a confining pressure of 40 kPa. These stress-strain data were used as input parameters for evaluating the vertical compressive strain at the top of subgrade soils using elastoplastic finite-element analysis. This vertical compressive strain at the top of unreinforced and reinforced subgrade soils was used for estimating the improvement in service life of the pavement or reduction in thicknesses of different layers for the same service life due to reinforcing the subgrade soils.

Development of Coordinated Schedules using Genetic Algorithms

Abstract: Suburban trains and public buses can play a better role in public transportation if they are coordinated Coordination of these two services will reduce the journeys made by intermediate public transport services and private vehicles from railway stations, which have become major traffic generators Thus, congestion, delays, and environmental pollution due to these services can be reduced to a great extent In this study, the Andheri and Vileparle suburban railway stations in Mumbai, India are taken as study locations, and schedule coordination between suburban trains and public buses [Bombay Electric and Suburban Transport (BEST) buses] at these suburban railway stations is attempted The coordinated schedules of BEST buses have been determined on already developed feeder routes for these two stations using the schedule optimization model (SOM) The objective function of the SOM is the minimization of transfer time between two services and vehicle operating costs of BEST buses The objective function and

Analysis of interactions among barriers in project risk management

Abstract: In the context of the scope, time, cost, and quality constraints, failure is not uncommon in project management. While small projects have 70% chances of success, large projects virtually have no chance of meeting the quadruple constraints. While there is no dearth of research on project risk management, the manifestation of barriers to project risk management is a less dwelt topic. The success of project management is oftentimes based on the understanding of barriers to effective risk management, application of appropriate risk management methodology, proactive leadership to avoid barriers, workers’ attitude, adequate resources, organizational culture, and involvement of top management. This paper represents various risk categories and barriers to risk management in domestic and international projects through literature survey and feedback from project professionals. After analysing the various modelling methods used in project risk management literature, interpretive structural modelling (ISM) and MICMAC analysis have been used to analyse interactions among the barriers and prioritize them. The analysis indicates that lack of top management support, lack of formal training, and lack of addressing cultural differences are the high priority barriers, among many others.

Risk management in medical product development process using traditional FMEA and fuzzy linguistic approach: a case study

Abstract: Medical product development (MPD) process is highly multidisciplinary in nature, which increases the complexity and the associated risks. Managing the risks during MPD process is very crucial. The objective of this research is to explore risks during MPD in a dental product manufacturing company and propose a model for risk mitigation during MPD process to minimize failure events. A case study approach is employed. The existing MPD process is mapped with five phases of the customized phase gate process. The activities during each phase of development and risks associated with each activity are identified and categorized based on the source of occurrence. The risks are analyzed using traditional Failure mode and effect analysis (FMEA) and fuzzy FMEA. The results of two methods when compared show that fuzzy approach avoids the duplication of RPNs and helps more to convert cognition of experts into information to get values of risk factors. The critical, moderate, low level and negligible risks are identified based on criticality; risk treatments and mitigation model are proposed. During initial phases of MPD, the risks are less severe, but as the process progresses the severity of risks goes on increasing. The MPD process should be critically designed and simulated to minimize the number of risk events and their severity. To successfully develop the products/devices within the manufacturing companies, the process risk management is very essential. A systematic approach to manage risks during MPD process will lead to the development of medical products with expected quality and reliability. This is the first research of its kind having focus on MPD process risks and its management. The methodology adopted in this paper will help the developers, managers and researchers to have a competitive edge over the other companies by managing the risks during the development process.

The public library system in India: challenges and opportunities

Abstract: Purpose – The current situation of Indian public libraries has been viewed by some as follows: the public library system in India is condemned to remain peripheral to the actual information needs of the masses; that it is in a depressed state, and serves as little more than a warehouse of recreational reading materials, a majority of which are in regional languages. This paper suggests possible remedies on how to transform the situation, and details new technological developments which are already showing the potential to change public libraries in rural India for the better.Design/methodology/approach – A descriptive account of the contemporary situation in India with regard to public libraries, digital technologies and development possibilities, using official statistics and the LIS literature.Findings – The challenges that face public libraries in India are listed and a vision for their future based on the concept of “ICT for development” is sketched out.Research limitations/implications – It is diffic...
