Design and optimisation of charging ingredients and structure in an ironmaking system (Part II)

In order to maximise the reduction of pig iron cost in an ironmaking process, and at the same time ensure the output and quality of the pig iron, a design and optimisation system for the charging ingredients and structure in an ironmaking system was established using metallurgical theory. The system includes six modules, namely, sinter metallurgical performance testing and analysis, sintering burdening design, sinter component and property prediction, blast furnace burdening design, blast furnace batching calculation and ironmaking system burden optimisation. Based on actual production, testing and material balance theory, the system integrated these modules on VB and MATLAB using a series of intelligent algorithms, such as the BP neural network, multiple objective linear programming, genetic algorithms and so on. As a result, the optimum burden composition and structure of the sinter and blast furnace that satisfied all the constraint conditions could be obtained. Standing as a pinnacle of the global ironmaking production, the system can design and optimise not only the sintering burden, but also the blast furnace burden. Compared with the traditional production testing and hand calculation in the ironmaking system, the project can greatly reduce the production risk and greatly increase the calculation accuracy. Industrial application shows that the system is especially beneficial to reduce the ironmaking cost and at the same time ensure the output and quality.     

Impressions of psychotherapists' offices.

For counseling settings, research suggests that softness, personalization, and order might affect the experience and the perceived expertness, trustworthiness, and social attractiveness of the therapist. This article discusses exploratory studies on college students' perception of the counseling office environment and whether the likely client experience was associated with the softness/personalization and order of the office. As stimuli, the studies used 30 color photographs of psychotherapists' offices viewed from the client's perspective. After obtaining ratings of the characteristics of each office, we obtained ratings from different groups of students of the quality of care and comfort expected in each office (Study 1) and how qualified, bold, and friendly the therapist in the office would be (Study 2). Additional studies examined the likelihood of choosing a therapist based on the office, and the first thought or feeling that came to mind about the office, the therapist, and the patient experience. There were strong correlations in response between groups (by whether they had experienced therapy; their level in school; their gender; and their major, location, and school size). The quality of care, comfort, therapist boldness, qualifications of the therapist, and the likelihood that one would choose a therapist based on the office improved with increases in the office's softness/personalization and order. Friendliness improved with increases in softness/personalization. The office choices, open-ended responses, and reported reasons for the ratings confirmed the importance of softness (comfort) and order. Research should test longer term exposure and behavior.

Lunar Astronomical Observatories: Design Studies

The best location in the inner solar system for the grand observatories of the 21st century may be the Moon. A multidisciplinary team including university students and faculty in engineering, astronomy, physics, and geology, and engineers from industry is investigating the Moon as a site for astronomical observatories and is doing conceptual and preliminary designs for these future observatories. Studies encompass lunar facilities for radio astronomy and astronomy at optical, ultraviolet, and infrared wavelengths of the electromagnetic spectrum. Although there are significant engineering challenges in design and construction on the Moon, the rewards for astronomy can be great, such as detection and study of Earth‐like planets orbiting nearby stars, and the task for engineers promises to stimulate advances in analysis and design, materials and structures, automation and robotics, foundations, and controls. Fabricating structures in the reduced‐gravity environment of the Moon will be easier than in the zero‐gravity environment of Earth orbit, as Apollo and space‐shuttle missions have revealed. Construction of observatories on the Moon can be adapted from techniques developed on the Earth, with the advantage that the Moon's weaker gravitational pull makes it possible to build larger devices than are practical on Earth.     

C. Shaler Smith

Smith was one of the premier bridge builders of the post-Civil War period. He started his bridge building career under Albert Fink on the Louisville and Nashville Railroad. During the Civil War, he designed and built a powder factory for the Confederacy at Augusta, Ga. After the war, he formed Smith and Latrobe Co. and later The Baltimore Bridge Company with Benjamin and C. H. Latrobe. He worked closely with James Eads on the St. Louis Bridge and designed and built the long iron easterly approach to the bridge. He designed and built some of the major viaducts, swing, and fixed span bridges in the United States, Australia, and Peru, and finally innovative cantilever bridges over the Kentucky, Mississippi, and St. Lawrence Rivers.

Development Model for Competitive Construction Industry in the People’s Republic of China

This paper identifies and analyzes the open-policy trend of the Chinese construction industry, which is characterized by trade liberalization, the underlying principle of the World Trade Organization (WTO). Compared to the construction industries in the United States, Japan, and the U.K., the construction industry in China is less developed in its legal framework, industrial structure, technological level, and international market share. To develop a competitive construction industry, the Chinese construction industry needs not only to accommodate appropriate international practice, but also to adapt and adopt it according to the market environment in China. A model to enhance the performance of the Chinese construction industry is proposed. The model consists of six modules: defining government’s role, opening up the construction market and establishing a competitive mechanism, promoting design institutes’ services and empowering professional bodies, encouraging technological innovations, upgrading employees’ educational level, and adopting multiprocurement routes. Recognizing China’s recent accession to the WTO and the attendant boost to its economy and industry development, the paper gives a timely evaluation of the post-WTO Chinese construction industry and proposes a model for its development. The model may serve the needs of academics, Chinese construction policymakers, construction enterprises, design institutes, and foreign contractors.     

Review of Attachment in psychotherapy.

Reviews the book, Attachment in psychotherapy by David J. Wallin (see record 2007-05421-000). This intellectual and clinical tour-de-force is what we have been waiting for: a book that is on the one hand a coherent, creative, thoughtful, and remarkably integrated view of contemporary psychoanalysis, with attachment, and attachment processes, at its core, and on the other a reflection on our daily, complex, work with patients. The book has three broad aims: first, to ground the reader in attachment theory and research, second, to broaden the reach of attachment theory by building bridges to other aspects of contemporary psychoanalytic theory and science, and third to apply this broader, deeply psychoanalytic, clinical attachment theory to understanding the dynamics of an individual patient and the dynamics of clinical work. This book should be essential reading for anyone interested in contemporary psychoanalysis. Few writers have the ability to write so directly and clearly about complex science and theory; his scholarship and reach are extraordinary. This book is also a book for therapists at all levels of experience. Throughout every section of the book, Wallin writes about his work with patients, about the therapeutic process, about the therapeutic situation, and about the therapeutic relationship, in all its complexity. In the end, he creates a truly contemporary vision of human development, affect regulation, and relational processes, grounded in the body and in the brain, and in the fundamental relationships that make us who we are, as therapists, as patients, and as human beings.
