Time Point

The paper deals with voltage profiles in a power system. The analysis of these profiles is important due to the requirement that the Root-Mean-Squared (RMS) values of nodal voltages should be within certain ranges, as well as to ensure desired power flows in a power system. In both cases, it is desirable to indicate points in a power system where it is reasonable to apply remedial measures to meet the requirements for RMS values of nodal voltages, or to effectively control the power flows in a power system. In general, candidate nodes for remediation are established based on operational experience or measurement data from a certain time point (sometimes from several time points). The paper presents a method that provides a basis for determining the aforementioned candidate nodes based on the behavior of a system over a certain period of time, which is an unquestionable advantage of this proposal. In order to achieve the abovementioned goal, the method provides for the analysis of propagation of voltage RMS value deviations in a power system. The analysis of correlational relationships between the RMS values of nodal voltages is used for this. After presentation of the theoretical background, the new original method is described in the paper. Then, case studies showing the utilization of that method are presented. At the end of the paper, features of the proposed method are enumerated.

Testing Case

A study was conducted in Taiwan of the quality control of drilled shafts using nondestructive testing. Ultrasonic borehole logging used for borehole quality control is introduced. Experiences from incorporation of nondestructive test methods into contract documents during the design phase, the use of a specification for acceptance of a pile during construction, and remedial measures are discussed. Three projects on quality control of drilled piles using nondestructive tests are evaluated. Interpretation based on the test results used to reach a decision for acceptance or rejection of a pile is discussed for the case studies.

River science and engineering has been one of the important study areas for geologists, hydrologists and engineers. The open channel flow and associated hydraulics often initiate several geomechanical hazards including silting and scouring, meandering and migration, floods, etc. Such hazards may lead to disastrous consequences if adequate remedial measures are not undertaken by proper river training works. This paper presents selected case studies in northern and north-eastern parts of India where such hazards occurred due to migration of river channel and flooding of adjacent lands. The two study areas have been the Kosi and the Brahmaputra river basins. In the former study area, hazards took place due to eastward migration, whereas in the latter case, significant damages occurred due to scouring and erosion. The descriptions of the hazards occurred, and the mitigation techniques adopted have been briefly summarized in this paper. A critical analysis with prediction techniques for flood occurrence probability and erosion potential has been conducted as well. The relevant conclusions are drawn therefrom.

ABSTRACTThis paper seeks to develop a basic analytical framework that can be used to trace the environmental impacts of macroeconomic policies, and especially to identify where unforeseen negative environmental effects may occur and design remedial measures. The framework is based on a formal mathematical model which shows the second-best nature of macroeconomic policies in the presence of environmental externalities. The model confirms the empirically observed and intuitively appealing conclusion that it is the combination of macroeconomic policies and subsidiary imperfections (policy, market or institutional), rather than macroeconomic policies alone, that leads to environmental degradation. Several illustrative examples are presented from case studies in selected developing countries.

Nature of AECI is a complex array of interdependent activities-best organized chaos introducing challenges not encountered in other industries. The work is often seasonal; Each project is unique; Often involves remote sites with various access problems; The process is not as predictable; There is difficulty in applying automation; There is high potential for encountering unforeseen conditions; Costs can vary according to conditions; There is difficult to manage and supply utilities and other resources; Technical innovations are adopted at slower pace; Success is dependent upon the quality of its people; AECI is very customoriented; Products can be of mind-boggling size, cost, and complexity; The work is not performed in controlled conditions, therefore highly impacted by weather and other environmental conditions. Over 100 Surveys, case studies and literature studies were done and it is found that the AECI faces several increasing & complicated construction and non-construction challenges, of all these few are new and rest centuries old. This extensive exploratory research was carried out to explore all the AECI challenges that affect AECI PDLC processes and this research suggests the remedial measures specifically to housing sector, addresses AECI challenges that help to improve productivity and efficiencies in the AECI processes.

Abstract Dwellings with suspended floors and high radon levels are proving difficult to remediate. This paper reports on the experience of the Building Research Establishment in dealing with such dwellings. Brief details of the remediation of 14 houses are given, and comparisons are made between the effectiveness of the different techniques adopted. Natural ventilation, mechanical supply ventilation and mechanical extract ventilation are three techniques that have been used successfully as radon remedial measures. Preliminary results suggest that supply ventilation is more effective than extract ventilation.

ABSTRACTThis paper addresses the issue of corporate sustainability. It examines why achieving sustainability is becoming an increasingly vital issue for society and organisations, defines sustainability and then outlines a set of phases through which organisations can move to achieve increasing levels of sustainability. Case studies are presented of organisations at various phases indicating the benefits, for the organisation and its stakeholders, which can be made at each phase. Finally the paper argues that there is a marked contrast between the two competing philosophies of neo-conservatism (economic rationalism) and the emerging philosophy of sustainability. Management schools have been strongly influenced by economic rationalism, which underpins the traditional orthodoxies presented in such schools. Sustainability represents an urgent challenge for management schools to rethink these traditional orthodoxies and give sustainability a central place in the curriculum.
