Experimental and Finite Element Analysis of External ALC Panel Steel Frames with New Semi-Rigid Connector

In this paper, a new ALC panel connector was proposed. It has a good engineering economy and high fault tolerance. A quasistatic loading experiment was carried out to verify the feasibility of the external ALC panel steel frame under seismic loading. The test phenomena, hysteretic curve, skeleton curve, stiffness degradation, and energy dissipation of two sets of full-scale specimens were analyzed and discussed. Moreover, the simulation of pendulous Z-panel connectors with different thicknesses was carried out using ABAQUS software. The comparison reveals that the semi-rigid connection has a full hysteresis curve, good energy dissipation capacity, and a 15% increase in peak load capacity. Finally, similar results for different thicknesses in the use of pendulous Z-panel connectors reveal that using the 6 mm connector may be the most economical solution for engineering.

Application of Fuzzy Analytic Hierarchy Process and Three-Dimensional Terrain Model in Traffic Routes Selection

The selection of a road route plan is an essential preliminary task. The choice of the route greatly influences its function, role in the road network, economic development of the areas along the route, and the return on investment. In this paper, qualitative analysis and evaluation of the details of the proposed route options in terms of ecological environment and engineering economy are carried out through fuzzy hierarchical analysis, based on the route data from Bushang to Bizhou, to combine the principles of the routes and develop several route options. Among the pre-determined route options, screening and comparison are carried out, and Option II is proposed as the recommended route.

Industrial destabilisation: The case of Rajajinagar, Bangalore

There has been a recent interest in expanding the focus of deindustrialisation studies to the cities of the Global South. Bangalore, with its long legacy of state sponsored industrialisation, as well as a substantial shift in its economy following economic liberalisation in 1991, presents itself as a suitable case to examine the impacts of industrial transformation. We study the decline of the engineering economy in one of Bangalore’s earliest planned industrial suburbs, Rajajinagar, to understand how industrial restructuring at the city and national scale has affected and reconfigured local economies. Using this case study, we make two main theoretical contributions: one, we bring out shifts at a neighbourhood scale that go beyond the existing literature on neoliberal transformations in Bangalore as well as other Indian cities. Two, the case also allows us to assess the limitations of deindustrialisation as a framework to analyse these changes, and we suggest a modified framework, that of ‘industrial destabilisation’.

Asociatividad y liderazgo con productores agropecuarios del Departamento del Quindío

El fortalecimiento organizacional de las asociaciones de productores del Departamento del Quindío en cabeza de sectores como el porcícola, cunícula, hortofrutícola, son ejes estratégicos para la Universidad del Quindío y con el que se busca que los productores agropecuarios de los municipios, tengan la capacidad de aplicar los procesos tecnológicos en la transformación vegetal, cárnica y láctea, a su vez creando y manteniendo una adecuada marca de sus productos y empresas, situación que beneficiara el sostenimiento de estos, junto con su plan de negocio, en el mercado comercial. La base para fundamentar dichos procesos es: liderazgo, trabajo en equipo, asociatividad, en aras del desarrollo local y regional. Esto como resultante del trabajo interdisciplinar que la Uniquindío ha realizado desde sus Vicerrectorías, Facultades y programas como lo son Vicerrectoría de Investigaciones, Vicerrectoría de Extensión y Desarrollo Social, las Facultades de Ciencias Agroindustriales, Ciencias Económicas y administrativas y la Ciencias Humanas y Bellas Artes y los Programas de Tecnología Agropecuaria, Tecnología Agroindustrial, Ingeniería de Alimentos, Economía, Trabajo social y Comunicación social-Periodismo, que a través de sus interacción han logrado las aplicaciones tecnológicas en la trasformación de materias primas que se generan como resultado de un proceso de indagación e investigación en los procesos de formulación de empresa de los productores agropecuarios de los municipios de del Departamento, particularmente de los municipios de Filandia, Circasia, Quimbaya, Pijao, Buenavista, Génova y Córdoba. head of sectors such as pig, cunícula, hortofrutícola, are strategic axes for the University of Quindío and with which it is sought that the agricultural producers of the municipalities, have the capacity to apply the technological processes in the vegetable, meat and dairy processing, in turn creating and maintaining an adequate brand of their products and companies, a situation that will benefit the sustainability of these, together with their business plan, in the commercial market. The basis to base these processes is: leadership, teamwork, associativity, in the interest of local and regional development. This as a result of the interdisciplinary work that Uniquindío has carried out from its Vice-Rectories, Faculties and programs such as Vice-Rector for Research, Vice-Rector for Extension and Social Development, the Faculties of Agroindustrial Sciences, Economic and Administrative Sciences and the Human Sciences and Fine Arts and the Programs of Agricultural Technology, Agroindustrial Technology, Food Engineering, Economy, Social Work and Social Communication-Journalism, which through their interaction have achieved technological applications in the transformation of raw materials that are generated as a result of a process of inquiry and research in business formulation processes of agricultural producers in the municipalities of the Department, particularly in the municipalities of Filandia, Circasia, Quimbaya, Pijao, Buenavista, Genoa and Córdoba..

A REVIEW STUDY OF ECONOMICS ANALYSIS IN ENGINEERING PROJECTS

Engineering economics, previously known as engineering economy, is a subset of economics concerned with the use and application of economic principles in the analysis of engineering decisions. As a discipline, it is focused on the branch of economics known as microeconomics in that it studies the behavior of individuals and firms in making decisions regarding the allocation of limited resources. Thus, it focuses on the decision making process, its context and environment. It is pragmatic by nature, integrating economic theory with engineering practice. But, it is also a simplified application of microeconomic theory in that it avoids a number of microeconomic concepts such as price determination, competition and demand/supply. As a discipline though, it is closely related to others such as statistics, mathematics and cost accounting. It draws upon the logical framework of economics but adds to that the analytical power of mathematics and statistics. Engineers seek solutions to problems, and the economic viability of each potential solution is normally considered along with the technical aspects. Fundamentally, engineering economics involves formulating, estimating, and evaluating the economic outcomes when alternatives to accomplish a defined purpose are available. The study includes an introduction to the application of economic techniques to the evaluation of design and engineering alternatives, cash flow concepts, interest factors, comparison of alternatives, benefit - cost analysis, and conclusions of the study. One of the objectives of the economic analysis in engineering projects is the good management which consists primarily of making wise decisions; wise decisions in turn involve making a choice between alternatives. Engineering considerations determine the possibility of a project being carried out and point out the alternative ways in which the project could be handled. Economic considerations also largely determine a project's desirability and dictate ho

Fuzzy sets theory and applications in engineering economy: A literature review

Engineering economics is an essential issue in investments and can be quietly difficult to make decisions especially in indefinite, vague and incomplete environments because of human thought. Usage of fuzzy sets gives better solutions in vagueness. Fuzzy sets could be an agreeable tool when no probabilities are accessible for states of nature and decisions are given under incompleteness. In this study, fuzzy engineering economics studies are summarized for showing fuzzy sets usage in engineering economics applications and finding gaps for future studies. The possible suggested are given in conclusion.
