Evaluating the life cycle of buildings is a valuable tool for assessing sustainability and analyzing environmental consequences throughout the construction operations of buildings. In this study, in order to determine the importance of building life cycle evaluation indicators, a new combination method was used based on a quantitative-qualitative method (QQM) and a simplified best-worst method (SBWM). The SBWM method was used because it simplifies BWM calculations and does not require solving complex mathematical models. Reducing the time required to perform calculations and eliminating the need for complicated computer software are among the advantages of the proposed method. The QQM method has also been used due to its ability to evaluate quantitative and qualitative criteria simultaneously. The feasibility and applicability of the SBWM were examined using three numerical examples and a case study, and the results were evaluated. The results of the case study showed that the criteria of the estimated cost, comfort level, and basic floor area were, in order, the most important criteria among the others. The results of the numerical examples and the case study showed that the proposed method had a lower total deviation (TD) compared to the basic BWM. Sensitivity analysis results also confirmed that the proposed approach has a high degree of robustness for ranking and weighting criteria.

Constructing highway pavements faces complex problems, which are affected by multiple factors, where solution is nearly impossible without expert assistance. Diagnosing such construction problems and suggesting most suitable cost efficient solutions requires significant engineering expertise, which might not be available in all construction sites due to inadequate resource and remote locations. Developing an expert system in this domain is a very effective way to help novice engineers to overcome these problems and to learn about them. Moreover, the system can be used as an archive to document engineering knowledge and to share expertise among the experts in this domain. This article describes the development and evaluation stages of such a system, including knowledge acquisition, knowledge representation, system building, and system verification and validation. The initial knowledge is acquired from literature reviews. More expert knowledge is elicited through interviews and questionnaires. This knowledge is documented, analyzed, represented, and converted to computer software using the Visual Basic programming language and the system is called ES-CCPRHP. The system has been verified and validated in three ways: by extensive testing, comparison between system performance and expert reasoning, and case study. It can therefore be employed with confidence by end users.

Small Modular Reactors (SMRs) have been recognized to have potential in decarbonizing district heating, which is currently an urgent sustainability challenge in many European countries. In this paper, the financial impacts of replacing peat and biomass-powered Combined Heat and Power (CHP) plants with heat-only reactors of 24–200 MW power range and maximum output temperatures of 120 °C are studied. A district heating system of a medium-sized Nordic city in Eastern Finland is modeled with EnergyPRO computer software (EMD International A/S, Aalborg, Denmark), which is used to optimize plant units’ production for cost effectiveness. A future scenario is used to predict electricity prices, expenditures from CO2 emission allowances, and fuel prices for the studied case. Results show that the low operating expenditures of CO2 free heat-only reactors would compensate for the revenue losses from electricity sales and that a small number of micro reactors, with power output in the tens of megawatts range each, would be optimal for the studied case. Since investment cost estimates for SMRs still bear significant uncertainties, the subject should be followed in further studies, as heat-only SMRs could provide a profitable alternative for current CHP production in the future.

Capstone Design

This paper describes an NSF funded project in the Mechanical and Aerospace Engineering (MAE) Department at the University of Missouri. A primary goal of this project is to systematically increase project-based learning (PBL) experiences throughout the MAE curriculum. To accomplish this goal, recent capstone design projects that need further refinements serve as the basis for PBL activities throughout the MAE curriculum. A major tool for facilitating these refinement efforts is a new senior/graduate Design Management course in which each student in this course learns how to plan and manage design projects. These students then implement their learning by serving as project team managers in the courses in which the refinement activities are being conducted. This paper provides a detailed case study of five refinements to one capstone design that took place in four different MAE courses during the Spring 2011 semester. The paper describes a Fall 2009 capstone project that consisted of designing a portable wood chipper. The student design was very promising, leading to a chipper with significantly greater chipping capacity than commercially available chippers of the same size and weight. However, several faculty members reviewed the results and identified additional opportunities for refining the design. This paper describes activities during Spring 2011 when students in four different MAE courses developed refinements to the original design. The roles of the Design Management students in these activities are discussed. The paper also includes a discussion of the methods and findings of the formative assessment process, including interviews with, and surveys of, faculty and students.

Technology Migration

AbstractThe paper illustrates a practical example of technology migration applied to the colour space converter realized in CMOS technology. The element has analogue excitation and response signals expressed in current mode. Such converter may be incorporated into an integrated vision sensor for preconditioning acquired image data. The idea of a computer software tool supporting the automated migration and design reuse is presented as the major contribution. The mentioned tools implement the Hooke-Jeeves direct search method for performing the multivariable optimization. Our purpose is to ensure transferring the circuit between usable fabrication technologies and preserving its functional properties. The colour space converter is treated as the case study for performance evaluation of the proposed tool in cooperation with HSPICE simulation software. The original CMOS technology files for Taiwan semiconductor (TSMC) plant were utilized for the research. The automated design migration from 180 nm into 90 nm resulted with obtaining compact IC layout characterized by a smaller area and lower power consumption. The paper is concluded with a brief summary that proves the usability of the proposed tool in designing CMOS cells dedicated for low power image processing.

This study aimed to perform a case study of the artworks colored using mixed media by applying qualitative methods. The teacher and the students wrote the story and completed the storyboard through interactive discussion teaching. With the knowledge of the properties of current painting papers and media used for coloring, the teacher was able to guide the students to choose paper of better quality, and select proper mixed media to create their artworks, so that the picture book could be richer and more delicate. Furthermore, documentary analysis was performed with current documents related to picture books to provide the students references for their artworks. Finally, the students were guided to process their graphs and arrange the layout using computer software, to complete a picture book artwork colored using mixed media by both hand-drawing and computer graphing and this study.
