2015-07-15

Built environments that are usable by all provide opportunities for engagement in meaningful occupations. However, enabling them in day to day design processes and practice is problematic for relevant professions. The purpose of this phenomenological study was to gain greater understanding of the policy and regulatory influences that promote or hinder the uptake of universal design in built environments, to inform better future design. Focus groups or telephone interviews were undertaken with 28 key building industry and disability stakeholders in Australia. Four themes were identified: the difficulties of definition; the push or pull of regulations and policy; the role of formal standards; and, shifting the focus of design thinking. The findings highlight the complexity of working within policy and regulatory contexts when implementing universal design. Occupational therapists working with colleagues from other professions must be aware of these influences, and develop the skills to work with them for successful practice.

Katapally, Tarun Reddy; Rainham, Daniel; Muhajarine, Nazeem

2016-01-01

With emerging evidence indicating that independent of physical activity, sedentary behaviour (SB) can be detrimental to health, researchers are increasingly aiming to understand the influence of multiple contexts such as urban design and built environment on SB. However, weather variation, a factor that continuously interacts with all other environmental variables, has been consistently underexplored. This study investigated the influence of diverse environmental exposures (including weather variation, urban design and built environment) on SB in children. This cross-sectional observational study is part of an active living research initiative set in the Canadian prairie city of Saskatoon. Saskatoon's neighbourhoods were classified based on urban street design into grid-pattern, fractured grid-pattern and curvilinear types of neighbourhoods. Diverse environmental exposures were measured including, neighbourhood built environment, and neighbourhood and household socioeconomic environment. Actical accelerometers were deployed between April and June 2010 (spring-summer) to derive SB of 331 10-14 year old children in 25 one week cycles. Each cycle of accelerometry was conducted on a different cohort of children within the total sample. Accelerometer data were matched with localized weather patterns derived from Environment Canada weather data. Multilevel modeling using Hierarchical Linear and Non-linear Modeling software was conducted by factoring in weather variation to depict the influence of diverse environmental exposures on SB. Both weather variation and urban design played a significant role in SB. After factoring in weather variation, it was observed that children living in grid-pattern neighbourhoods closer to the city centre (with higher diversity of destinations) were less likely to be sedentary. This study demonstrates a methodology that could be replicated to integrate geography-specific weather patterns with existing cross-sectional accelerometry data to

Ern, Peniel Ang Soon; Ling, Lim Mei; Kasim, Narimah; Hamid, Zuhairi Abd; Masrom, Md Asrul Nasid Bin

2017-10-01

Malaysia’s awareness of performance criteria in construction industry towards a sustainable built environment with the use of precast concrete sandwich panel (PCSP) system is applied in the building’s wall to study the structural behaviour. However, very limited studies are conducted on the thermal insulation of exterior and interior panels in PCSP design. In hot countries such as Malaysia, proper designs of panel are important to obtain better thermal insulation for building. This study is based on thermal performance of precast concrete sandwich panel design for sustainable built environment in Malaysia. In this research, three full specimens, which are control specimen (C), foamed concrete (FC) panels and concrete panels with added palm oil fuel ash (FC+ POFA), where FC and FC+POFA sandwiched with gypsum board (G) were produced to investigate their thermal performance. Temperature difference of exterior and interior surface of specimen was used as indicators of thermal-insulating performance of PCSP design. Heat transfer test by halogen lamp was carried out on three specimens where the exterior surface of specimens was exposed to the halogen lamp. The temperature reading of exterior and interior surface for three specimens were recorded with the help of thermocouple. Other factors also studied the workability, compressive strength and axial compressive strength of the specimens. This study has shown that FC + POFA specimen has the strength nearer to normal specimen (C + FC specimen). Meanwhile, the heat transfer results show that the FC+POFA has better thermal insulation performance compared to C and FC specimens with the highest temperature difference, 3.4°C compared to other specimens. The results from this research are useful to be implemented in construction due to its benefits such as reduction of energy consumption in air-conditioning, reduction of construction periods and eco-friendly materials.

Skruch, B.R.; Brandt, G.B.; Denes, L.J.

1984-01-01

Techniques are being developed for acquisition, recording, and evaluation of as-built measurements of piping systems in nuclear power plants. The goal is to improve the efficiency with which as-built dimensions and configuration can be compared to as-designed dimensions and configuration. The approach utilizes an electronic digital ''ruler'' capable of measuring distances to 100 feet with a resolution of 1/100 of a foot. This ruler interfaces to a hand held computer. This ''electronic notebook'' also accepts alpha-numeric input from a keyboard and replaces a clipboard and pencil currently used. The electronic notebook, in turn, can transfer its data directly to a host mini or mainframe computer. Once the data is resident on the larger computer it is converted to a format compatible with an existing database system used for piping analysis and design. Using accepted tolerances for as-built deviations, the as-built data is then automatically compared to as-designed data. If reanalysis is required, the as-built data is in a compatible format to utilize existing computer analysis codes. This paper discusses the operation and interfacing of the electronic ruler, the general design of the data structures in the electronic notebook, the design of mini-computer software, and the results of preliminary testing of the system

The short paper presents preliminary findings from a pilot study on how students become motivated through design of learning games in math. The research is carried out in a Danish public school with two classes of 5th graders (N = 42 students). Over the course of two weeks, the students work...... with a design template for a runner game in the Unity 3D game design engine. The students are introduced to the concept of “flow” (Csikszentmihalyi, 1991) as a game design principle and are asked to design levels for a math runner game, which are both engaging as well as a meaningful way of learning math....... In this way, the students are positioned as “math level designers”, which means that they both have to redesign the difficulty of the runner game as well as the difficulty of the mathematical questions and possible answers....

RED or READ: the built environment is colored

Science.gov (United States)

Smith, Dianne

2002-06-01

How important is color in the design of our built environment? Prototypes and massing models for designs are often presented in white or monochromatic combinations, irrespective of the materials incorporated and the colors that may be applied in the final constructed building, interior or object. Therefore, it is of interest to identify the way color is positioned by designers in how they go about the business of making environments. The built environment is understood by the designers and design researchers generally in one of four fields - as object, as product, as communicator, or as social domain. In addition, Franz identified four conceptions of designing held by designers - the experiential conception, the structural conception, the production conception and the retail conception. Fashion and style are often associated with color in a local context and may simply be applied to the physical environment because it is in fashion, rather than because of what it communicates more broadly. It is assumed that the integration of color in the built environment is influenced by these understandings. In order to address color's position in the design process and the importance of color in relation to space, form, and the experience of place, a selection of Queensland architects and interior designers were surveyed. The study is not conclusive, however, it does identify differences and commonalities between the participants that are of interest in light of the above issues. Explorations into environmental meaning, in addition to color theory and decorative applications, are hypothesized to be important sources of information for designers involved in the coloration of the built environment.

Dixon, J.; Walker, B.

1999-01-01

Full text: In December 1997, the Department of Nuclear Medicine relocated to new purpose-built premises. Two years of detailed planning preceded this move. Several innovative features were incorporated in the design. The 6 gamma camera rooms are arranged in pairs with shared shielded console areas, around a central 'staff-only' corridor with the radiopharmacy dispensing room (RP) at one end. This allows for direct staff access between these rooms while preserving the privacy of the patients. Hatches from the RP to the stress lab and procedures rooms allow for minimal carrying of doses. A separate hotlab adjoining the RP with a dedicated dose calibrator is used for preparations of all therapy doses and 18 F. A 'no return' policy was adopted for the RP. A separate isolated radioactive waste storage room (WSR) has an easily accessible anteroom used only for 99 Tc m , which allows efficient management of this short-lived waste. The nurses' station visualizes all waiting facilities, which include separate areas for trolley and ambulant patients as well as a playroom for the paediatric patients. An area for resting 18 F patients is located away from the general waiting areas and close to the coincidence detection camera room. After 1 year of operation, these specific design features have proved successful. They have led to improvement in the efficiency of operation of the department for the staff and increased comfort for the patients

In this project a multi-disciplinary undergraduate team from CUA, comprising majors in Physics, Mechanical Engineering, Electrical Engineering, and Biology, design, build, test, fly, and analyze the data from a prototype attitude determination system (PADS). The goal of the experiment is to determine if an inexpensive attitude determination system could be built for high altitude research balloons using MEMS gyros. PADS is a NASA funded project, built by students with the cooperation of CUA faculty, Verner, Bruhweiler, and Abot, along with the contributed expertise of researchers and engineers at NASA/GSFC, Kogut, Lowe, Mirel, and Lazear. The project was initiated through a course taught in CUA's School of Engineering, which was followed by a devoted effort by students during the summer of 2014. The project is an experiment to use 18 MEMS gyros, similar to those used in many smartphones, to produce an averaged positional error signal that could be compared with the motion of the fixed optical system as recorded through a string of optical images of stellar fields to be stored on a hard drive flown with the experiment. The optical system, camera microprocessor, and hard drive are enclosed in a pressure vessel, which maintains approximately atmospheric pressure throughout the balloon flight. The experiment uses multiple microprocessors to control the camera exposures, record gyro data, and provide thermal control. CUA students also participated in NASA-led design reviews. Four students traveled to NASA's Columbia Scientific Balloon Facility in Palestine, Texas to integrate PADS into a large balloon gondola containing other experiments, before being shipped, then launched in mid-August at Ft. Sumner, New Mexico. The payload is to fly at a float altitude of 40-45,000 m, and the flight last approximately 15 hours. The payload is to return to earth by parachute and the retrieved data are to be analyzed by CUA undergraduates. A description of the instrument is presented

Operating systems and applications in the built environment have relied upon central authorization and management mechanisms which restrict their scalability, especially with respect to administrative overhead. We propose a new set of primitives encompassing syndication, security, and service execution that unifies the management of applications and services across the built environment, while enabling participants to individually delegate privilege across multiple administrative domains with no loss of security or manageability. We show how to leverage a decentralized authorization syndication platform to extend the design of building operating systems beyond the single administrative domain of a building. The authorization system leveraged is based on blockchain smart contracts to permit decentralized and democratized delegation of authorization without central trust. Upon this, a publish/subscribe syndication tier and a containerized service execution environment are constructed. Combined, these mechanisms solve problems of delegation, federation, device protection and service execution that arise throughout the built environment. We leverage a high-fidelity city-scale emulation to verify the scalability of the authorization tier, and briefly describe a prototypical democratized operating system for the built environment using this foundation.

Students’ Attitudes to Universal Design in Architecture Education

Directory of Open Access Journals (Sweden)

Helen Larkin

2016-12-01

Full Text Available It is widely recognised that the built environment can dramatically impact the participation and engagement of people with disability and diverse needs. It has therefore become necessary for architects and designers to consider these needs when working within their profession. The implementation of universal design teaching into architecture and design curriculum has been recognised as an important step in facilitating and enhancing the uptake of universal design during the design process. Using a quantitative approach, this study aimed to compare, contrast and explore the attitudes of two groups of architecture students to the universal design of built environments. One group had received education relating to diversity and universal design as part of a prior project while the other group had not received this content. Findings from this comparison demonstrated that overall, no significant differences between groups existed. However further investigation provided interesting insight and perspectives into student attitudes to universal design and potential influencers of these attitudes.

2013-01-01

Sustainable design is a collective process whereby the built environment achieves unprecedented levels of ecological balance through new and retrofit construction, with the goal of long-term viability and humanization of architecture. Focusing on the environmental context, sustainable design merges the natural, minimum resource conditioning solutions of the past (daylight, solar heat, and natural ventilation) with the innovative technologies of the present.  The desired result is an integrated “intelligent” system that supports individual control with expert negotiation for resource consciousness. International experts in the field address the fundamental questions of sustainable design and landscape management: How should the sustainability of landscapes and buildings be evaluated? Which targets have to be set and which thresholds should not be exceeded? What forms of planning and governance structures exist and to what extent do they further the goals of sustainability?  Gathering 30 peer-reviewed ent...

An approach for access differentiation design in medical distributed applications built on databases.

Shoukourian, S K; Vasilyan, A M; Avagyan, A A; Shukurian, A K

1999-01-01

A formalized "top to bottom" design approach was described in [1] for distributed applications built on databases, which were considered as a medium between virtual and real user environments for a specific medical application. Merging different components within a unified distributed application posits new essential problems for software. Particularly protection tools, which are sufficient separately, become deficient during the integration due to specific additional links and relationships not considered formerly. E.g., it is impossible to protect a shared object in the virtual operating room using only DBMS protection tools, if the object is stored as a record in DB tables. The solution of the problem should be found only within the more general application framework. Appropriate tools are absent or unavailable. The present paper suggests a detailed outline of a design and testing toolset for access differentiation systems (ADS) in distributed medical applications which use databases. The appropriate formal model as well as tools for its mapping to a DMBS are suggested. Remote users connected via global networks are considered too.

Design of a Realistic Test Simulator For a Built-In Self Test Environment

Directory of Open Access Journals (Sweden)

A. Ahmad

2010-12-01

Full Text Available This paper presents a realistic test approach suitable to Design For Testability (DFT and Built- In Self Test (BIST environments. The approach is culminated in the form of a test simulator which is capable of providing a required goal of test for the System Under Test (SUT. The simulator uses the approach of fault diagnostics with fault grading procedure to provide the tests. The tool is developed on a common PC platform and hence no special software is required. Thereby, it is a low cost tool and hence economical. The tool is very much suitable for determining realistic test sequences for a targeted goal of testing for any SUT. The developed tool incorporates a flexible Graphical User Interface (GUI procedure and can be operated without any special programming skill. The tool is debugged and tested with the results of many bench mark circuits. Further, this developed tool can be utilized for educational purposes for many courses such as fault-tolerant computing, fault diagnosis, digital electronics, and safe - reliable - testable digital logic designs.

Developing custom-built MR coils is a cumbersome task, in which an a priori prediction of the coils' SNR performance, their sensitivity pattern, and their depth of penetration helps to greatly speed up the design process by reducing the required hardware manufacturing iterations. The simulation-based design flow presented in this paper takes the entire MR imaging process into account. That is, it includes all geometric and material properties of the coil and the phantom, the thermal noise as well as the target MR sequences. The proposed simulation-driven design flow is validated using a manufactured prototype coil, whose performance was optimized regarding its SNR performance, based on the presented design flow, by comparing the coil's measured performance against the simulated results. In these experiments, the mean and the standard deviation of the relative error between the simulated and measured coil sensitivity pattern were found to be and . Moreover, the peak deviation between the simulated and measured voxel SNR was found to be less than 4%, indicating that simulations are in good accordance with the measured results, validating the proposed software-based design approach.

Buildings are complex ecosystems that house trillions of microorganisms interacting with each other, with humans and with their environment. Understanding the ecological and evolutionary processes that determine the diversity and composition of the built environment microbiome--the community of microorganisms that live indoors--is important for understanding the relationship between building design, biodiversity and human health. In this study, we used high-throughput sequencing of the bacterial 16S rRNA gene to quantify relationships between building attributes and airborne bacterial communities at a health-care facility. We quantified airborne bacterial community structure and environmental conditions in patient rooms exposed to mechanical or window ventilation and in outdoor air. The phylogenetic diversity of airborne bacterial communities was lower indoors than outdoors, and mechanically ventilated rooms contained less diverse microbial communities than did window-ventilated rooms. Bacterial communities in indoor environments contained many taxa that are absent or rare outdoors, including taxa closely related to potential human pathogens. Building attributes, specifically the source of ventilation air, airflow rates, relative humidity and temperature, were correlated with the diversity and composition of indoor bacterial communities. The relative abundance of bacteria closely related to human pathogens was higher indoors than outdoors, and higher in rooms with lower airflow rates and lower relative humidity. The observed relationship between building design and airborne bacterial diversity suggests that we can manage indoor environments, altering through building design and operation the community of microbial species that potentially colonize the human microbiome during our time indoors.

Zou, Xueli

2007-11-01

To help students develop the scientific abilities desired in the 21st century workplace, four different types of student design tasks—observation, verification, application, and investigation experiments—have been developed and implemented in our calculus-based introductory courses. Students working in small groups are engaged in designing and conducting their own experiments to observe some physical phenomena, test a physical principle, build a real-life device, solve a complex problem, or conduct an open-inquiry investigation. A preliminary study has shown that, probed by a performance-based task, the identified scientific abilities are more explicitly demonstrated by design-lab students than non-design lab students. In this paper, detailed examples of the design tasks and assessment results will be reported.

The societal demand for inspiring and engaging science, technology, engineering, and mathematics (STEM) students and preparing our workforce for the emerging creative economy has necessitated developing students' self-efficacy and understanding of engineering design processes from as early as elementary school levels. Hands-on engineering design activities have shown the potential to promote middle school students' self-efficacy and understanding of engineering design processes. However, traditional classrooms often lack hands-on engineering design experiences, leaving students unprepared to solve real-world design problems. In this study, we introduce the framework of a toy design workshop and investigate the influence of the workshop activities on students' understanding of and self-efficacy beliefs in engineering design. Using a mixed method approach, we conducted quantitative analyses to show changes in students' engineering design self-efficacy and qualitative analyses to identify students' understanding of the engineering design processes. Findings show that among the 24 participants, there is a significant increase in students' self-efficacy beliefs after attending the workshop. We also identified major themes such as design goals and prototyping in students' understanding of engineering design processes. This research provides insights into the key elements of middle school students' engineering design learning and the benefits of engaging middle school students in hands-on toy design workshops.

Abstract The zebrafish is a valuable model for teaching developmental, molecular, and cell biology; aquatic sciences; comparative anatomy; physiology; and genetics. Here we demonstrate that zebrafish provide an excellent model system to teach engineering principles. A seven-member undergraduate team in a biomedical engineering class designed, built, and tested a zebrafish microfluidic bioreactor applying microfluidics, an emerging engineering technology, to study zebrafish development. During the semester, students learned engineering and biology experimental design, chip microfabrication, mathematical modeling, zebrafish husbandry, principles of developmental biology, fluid dynamics, microscopy, and basic molecular biology theory and techniques. The team worked to maximize each person's contribution and presented weekly written and oral reports. Two postdoctoral fellows, a graduate student, and three faculty instructors coordinated and directed the team in an optimal blending of engineering, molecular, and developmental biology skill sets. The students presented two posters, including one at the Zebrafish meetings in Madison, Wisconsin (June 2008). PMID:19292670

The Advanced Envelope Research effort will provide factory homebuilders with high performance, cost-effective alternative envelope designs. In the near term, these technologies will play a central role in meeting stringent energy code requirements. For manufactured homes, the thermal requirements, last updated by statute in 1994, will move up to the more rigorous IECC 2012 levels in 2013, the requirements of which are consistent with site built and modular housing. This places added urgency on identifying envelope technologies that the industry can implement in the short timeframe. The primary goal of this research is to develop wall designs that meet the thermal requirements based on 2012 IECC standards. Given the affordable nature of manufactured homes, impact on first cost is a major consideration in developing the new envelope technologies. This work is part of a four-phase, multi-year effort. Phase 1 identified seven envelope technologies and provided a preliminary assessment of three selected methods for building high performance wall systems. Phase 2 focused on the development of viable product designs, manufacturing strategies, addressing code and structural issues, and cost analysis of the three selected options. An industry advisory committee helped critique and select the most viable solution to move further in the research -- stud walls with continuous exterior insulation. Phase 3, the subject of the current report, focused on the design development of the selected wall concept and explored variations on the use of exterior foam insulation. The scope also included material selection, manufacturing and cost analysis, and prototyping and testing.

Contextual Shaping of Student Design Practices: The Role of Constraint in First-Year Engineering Design

Science.gov (United States)

Goncher, Andrea M.

thResearch on engineering design is a core area of concern within engineering education, and a fundamental understanding of how engineering students approach and undertake design is necessary in order to develop effective design models and pedagogies. This dissertation contributes to scholarship on engineering design by addressing a critical, but as yet underexplored, problem: how does the context in which students design shape their design practices? Using a qualitative study comprising of video data of design sessions, focus group interviews with students, and archives of their design work, this research explored how design decisions and actions are shaped by context, specifically the context of higher education. To develop a theoretical explanation for observed behavior, this study used the nested structuration. framework proposed by Perlow, Gittell, & Katz (2004). This framework explicated how teamwork is shaped by mutually reinforcing relationships at the individual, organizational, and institutional levels. I appropriated this framework to look specifically at how engineering students working on a course-related design project identify constraints that guide their design and how these constraints emerge as students interact while working on the project. I first identified and characterized the parameters associated with the design project from the student perspective and then, through multi-case studies of four design teams, I looked at the role these parameters play in student design practices. This qualitative investigation of first-year engineering student design teams revealed mutual and interconnected relationships between students and the organizations and institutions that they are a part of. In addition to contributing to research on engineering design, this work provides guidelines and practices to help design educators develop more effective design projects by incorporating constraints that enable effective design and learning. Moreover, I found

To assess satisfaction with maternity waiting home built spaces and features in women who are at risk for underutilizing maternity waiting homes (i.e. residential facilities that temporarily house near-term pregnant mothers close to healthcare facilities that provide obstetrical care). Specifically we wanted to answer the questions: (1) Are built spaces and features associated with maternity waiting home user satisfaction? (2) Can built spaces and features designed to improve hygiene, comfort, privacy and function improve maternity waiting home user satisfaction? And (3) Which built spaces and features are most important for maternity waiting home user satisfaction? A cross-sectional study comparing satisfaction with standard and non-standard maternity waiting home designs. Between December 2016 and February 2017 we surveyed expectant mothers at two maternity waiting homes that differed in their design of built spaces and features. We used bivariate analyses to assess if built spaces and features were associated with satisfaction. We compared ratings of built spaces and features between the two maternity waiting homes using chi-squares and t-tests to assess if design features to improve hygiene, comfort, privacy and function were associated with higher satisfaction. We used exploratory robust regression analysis to examine the relationship between built spaces and features and maternity waiting home satisfaction. Two maternity waiting homes in Malawi, one that incorporated non-standardized design features to improve hygiene, comfort, privacy, and function (Kasungu maternity waiting home) and the other that had a standard maternity waiting home design (Dowa maternity waiting home). 322 expectant mothers at risk for underutilizing maternity waiting homes (i.e. first-time mothers and those with no pregnancy risk factors) who had stayed at the Kasungu or Dowa maternity waiting homes.

Smith, J.; Forsyth, T.; Sinclair, K.; Oteri, F.

2012-11-01

Although only a small contributor to total electricity production needs, built-environment wind turbines (BWTs) nonetheless have the potential to influence the public's consideration of renewable energy, and wind energy in particular. Higher population concentrations in urban environments offer greater opportunities for project visibility and an opportunity to acquaint large numbers of people to the advantages of wind projects on a larger scale. However, turbine failures will be equally visible and could have a negative effect on public perception of wind technology. This roadmap provides a framework for achieving the vision set forth by the attendees of the Built-Environment Wind Turbine Workshop on August 11 - 12, 2010, at the U.S. Department of Energy's National Renewable Energy Laboratory. The BWT roadmap outlines the stakeholder actions that could be taken to overcome the barriers identified. The actions are categorized as near-term (0 - 3 years), medium-term (4 - 7 years), and both near- and medium-term (requiring immediate to medium-term effort). To accomplish these actions, a strategic approach was developed that identifies two focus areas: understanding the built-environment wind resource and developing testing and design standards. The authors summarize the expertise and resources required in these areas.

Designed by Engineers: An analysis of interactionaries with engineering students

Directory of Open Access Journals (Sweden)

Henrik Artman

2014-12-01

Full Text Available The aim of this study is to describe and analyze learning taking place in a collaborative design exercise involving engineering students. The students perform a time-constrained, open-ended, complex interaction design task, an “interactionary”. A multimodal learning perspective is used. We have performed detailed analyses of video recordings of the engineering students, including classifying aspects of interaction. Our results show that the engineering students carry out and articulate their design work using a technology-centred approach and focus more on the function of their designs than on aspects of interaction. The engineering students mainly make use of ephemeral communication strategies (gestures and speech rather than sketching in physical materials. We conclude that the interactionary may be an educational format that can help engineering students learn the messiness of design work. We further identify several constraints to the engineering students’ design learning and propose useful interventions that a teacher could make during an interactionary. We especially emphasize interventions that help engineering students-retain aspects of human-centered design throughout the design process. This study partially replicates a previous study which involved interaction design students.

A Cache System Design for CMPs with Built-In Coherence Verification

Directory of Open Access Journals (Sweden)

Mamata Dalui

2016-01-01

Full Text Available This work reports an effective design of cache system for Chip Multiprocessors (CMPs. It introduces built-in logic for verification of cache coherence in CMPs realizing directory based protocol. It is developed around the cellular automata (CA machine, invented by John von Neumann in the 1950s. A special class of CA referred to as single length cycle 2-attractor cellular automata (TACA has been planted to detect the inconsistencies in cache line states of processors’ private caches. The TACA module captures coherence status of the CMPs’ cache system and memorizes any inconsistent recording of the cache line states during the processors’ reference to a memory block. Theory has been developed to empower a TACA to analyse the cache state updates and then to settle to an attractor state indicating quick decision on a faulty recording of cache line status. The introduction of segmentation of the CMPs’ processor pool ensures a better efficiency, in determining the inconsistencies, by reducing the number of computation steps in the verification logic. The hardware requirement for the verification logic points to the fact that the overhead of proposed coherence verification module is much lesser than that of the conventional verification units and is insignificant with respect to the cost involved in CMPs’ cache system.

The NL characteristic was obtained and designed by optimizing the internal filament location with a low effective dielectric constant in the HfO x /SiO x structure. The stacking HfO x /SiO x -based RRAM device as the one-resistor-only memory cell is applicable without needing an additional selector device to solve the sneak path issue with a switching voltage of ~1 V, which is desirable for low-power operating in built-in nonlinearity crossbar array configurations.

Designing Learning Opportunities in Interaction Design: Interactionaries as a means to study and teach student design processes

Directory of Open Access Journals (Sweden)

Robert Ramberg

2013-12-01

Full Text Available Learning by practice, apprenticeship and paradigmatic examples have been prime paths for learning within interaction design. These have been criticized for being time-consuming and costly, of not being implementable in academic contexts. In this article we suggest and evaluate a pedagogical model to address these problems in design teaching and learning. Results from a time-constrained collaborative design exercise, a so-called “interactionary”, are presented. Student design work is analyzed using the framework of learning design sequences and analysis of the primary transformation unit shows that interactionaries reveal patterns in student design work. Materials are used mainly to document design ideas rather than as a design material to further investigate design ideas and aspects of interaction. In the critiquing sessions, regarded as the secondary transformation unit, many issues hardly addressed during the design work were brought up. Thus, the designers continued to develop their design proposal primed by critique presented by the reviewers. Based on the results, possible teacher interventions to coach student design work are suggested.

Kaplan Thompson Architects (KTA) has specialized in sustainable, energy-efficient buildings, and they have designed several custom, zero-energy homes in New England. These zero-energy projects have generally been high-end, custom homes with budgets that could accommodate advanced energy systems. In an attempt to make zero energy homes more affordable and accessible to a larger demographic, KTA explored modular construction as way to provide high-quality homes at lower costs. In the mid-2013, KTA formalized this concept when they launched BrightBuilt Home (BBH). The BBH mission is to offer a line of architect-designed, high-performance homes that are priced to offer substantial savings off the lifetime cost of a typical home and can be delivered in less time. For the past two years, CARB has worked with BBH and Keiser Homes (the primary modular manufacturer for BBH) to discuss challenges related to wall systems, HVAC, and quality control. In Spring of 2014, CARB and BBH began looking in detail on a home to be built in Lincolnville, ME by Black Bros. Builders. This report details the solution package specified for this modular plan and the challenges that arose during the project.

Introduction The built environment is increasingly recognised as being associated with health outcomes. Relationships between the built environment and health differ among age groups, especially between children and adults, but also between younger, mid-age and older adults. Yet few address differences across life stage groups within a single population study. Moreover, existing research mostly focuses on physical activity behaviours, with few studying objective clinical and mental health outcomes. The Life Course Built Environment and Health (LCBEH) project explores the impact of the built environment on self-reported and objectively measured health outcomes in a random sample of people across the life course. Methods and analysis This cross-sectional data linkage study involves 15 954 children (0–15 years), young adults (16–24 years), adults (25–64 years) and older adults (65+years) from the Perth metropolitan region who completed the Health and Wellbeing Surveillance System survey administered by the Department of Health of Western Australia from 2003 to 2009. Survey data were linked to Western Australia's (WA) Hospital Morbidity Database System (hospital admission) and Mental Health Information System (mental health system outpatient) data. Participants’ residential address was geocoded and features of their ‘neighbourhood’ were measured using Geographic Information Systems software. Associations between the built environment and self-reported and clinical health outcomes will be explored across varying geographic scales and life stages. Ethics and dissemination The University of Western Australia's Human Research Ethics Committee and the Department of Health of Western Australia approved the study protocol (#2010/1). Findings will be published in peer-reviewed journals and presented at local, national and international conferences, thus contributing to the evidence base informing the design of healthy neighbourhoods for all residents.

Elementary Students' Acquisition of Academic Vocabulary Through Engineering Design

Science.gov (United States)

Kugelmass, Rachel

This study examines how STEM (science, technology, engineering, and mathematics) inquiry-based learning through a hands-on engineering design can be beneficial in helping students acquire academic vocabulary. This research took place in a second grade dual- language classroom in a public, suburban elementary school. English language learners, students who speak Spanish at home, and native English speakers were evaluated in this study. Each day, students were presented with a general academic vocabulary focus word during an engineering design challenge. Vocabulary pre-tests and post-tests as well as observation field notes were used to evaluate the student's growth in reading and defining the focus academic vocabulary words. A quiz and KSB (knowledge and skill builder) packet were used to evaluate students' knowledge of science and math content and engineering design. The results of this study indicate that engineering design is an effective means for teaching academic vocabulary to students with varying levels of English proficiency.

Creating meaningful learning experiences: Understanding students' perspectives of engineering design

Science.gov (United States)

Aleong, Richard James Chung Mun

There is a societal need for design education to prepare holistic engineers with the knowledge, skills, and attitudes to innovate and compete globally. Design skills are paramount to the espoused values of higher education, as institutions of higher learning strive to develop in students the cognitive abilities of critical thinking, problem solving, and creativity. To meet these interests from industry and academia, it is important to advance the teaching and learning of engineering design. This research aims to understand how engineering students learn and think about design, as a way for engineering educators to optimize instructional practice and curriculum development. Qualitative research methodology was used to investigate the meaning that engineering students' ascribe to engineering design. The recruitment of participants and corresponding collection of data occurred in two phases using two different data collection techniques. The first phase involved the distribution of a one-time online questionnaire to all first year, third year, and fourth year undergraduate engineering students at three Canadian Universities. After the questionnaire, students were asked if they would be willing to participate in the second phase of data collection consisting of a personal interview. A total of ten students participated in interviews. Qualitative data analysis procedures were conducted on students' responses from the questionnaire and interviews. The data analysis process consisted of two phases: a descriptive phase to code and categorize the data, followed by an interpretative phase to generate further meaning and relationships. The research findings present a conceptual understanding of students' descriptions about engineering design, structured within two educational orientations: a learning studies orientation and a curriculum studies orientation. The learning studies orientation captured three themes of students' understanding of engineering design: awareness

Elementary students' engagement in failure-prone engineering design tasks

Science.gov (United States)

Andrews, Chelsea Joy

Although engineering education has been practiced at the undergraduate level for over a century, only fairly recently has the field broadened to include the elementary level; the pre-college division of the American Society of Engineering Education was established in 2003. As a result, while recent education standards require engineering in elementary schools, current studies are still filling in basic research on how best to design and implement elementary engineering activities. One area in need of investigation is how students engage with physical failure in design tasks. In this dissertation, I explore how upper elementary students engage in failure-prone engineering design tasks in an out-of-school environment. In a series of three empirical case studies, I look closely at how students evaluate failed tests and decide on changes to their design constructions, how their reasoning evolves as they repeatedly encounter physical failure, and how students and facilitators co-construct testing norms where repetitive failure is manageable. I also briefly investigate how students' engagement differs in a task that features near-immediate success. By closely examining student groups' discourse and their interactions with their design constructions, I found that these students: are able to engage in iteration and see failure-as-feedback with minimal externally-imposed structure; seem to be designing in a more sophisticated manner, attending to multiple causal factors, after experiencing repetitive failure; and are able to manage the stress and frustration of repetitive failure, provided the co-constructed testing norms of the workshop environment are supportive of failure management. These results have both pedagogical implications, in terms of how to create and facilitate design tasks, and methodological implications--namely, I highlight the particular insights afforded by a case study approach for analyzing engagement in design tasks.

The Complex Dynamics of Student Engagement in Novel Engineering Design Activities

Science.gov (United States)

McCormick, Mary

In engineering design, making sense of "messy," design situations is at the heart of the discipline (Schon, 1983); engineers in practice bring structure to design situations by organizing, negotiating, and coordinating multiple aspects (Bucciarelli, 1994; Stevens, Johri, & O'Connor, 2014). In classroom settings, however, students are more often given well-defined, content-focused engineering tasks (Jonassen, 2014). These tasks are based on the assumption that elementary students are unable to grapple with the complexity or open-endedness of engineering design (Crismond & Adams, 2012). The data I present in this dissertation suggest the opposite. I show that students are not only able to make sense of, or frame (Goffman, 1974), complex design situations, but that their framings dynamically involve their nascent abilities for engineering design. The context of this work is Novel Engineering, a larger research project that explores using children's literature as an access point for engineering design. Novel Engineering activities are inherently messy: there are characters with needs, settings with implicit constraints, and rich design situations. In a series of three studies, I show how students' framings of Novel Engineering design activities involve their reasoning and acting as beginning engineers. In the first study, I show two students whose caring for the story characters contributes to their stability in framing the task: they identify the needs of their fictional clients and iteratively design a solution to meet their clients' needs. In the second, I show how students' shifting and negotiating framings influence their engineering assumptions and evaluation criteria. In the third, I show how students' coordinating framings involve navigating a design process to meet clients' needs, classroom expectations, and technical requirements. Collectively, these studies contribute to literature by documenting students' productive beginnings in engineering design. The

2014-10-01

External built residential environment characteristics include aspects of building design such as types of walls, doors and windows, green spaces, density of houses per unit area, and waste disposal facilities. Neighborhoods that are characterized by poor quality external built environment can contribute to psychosocial stress and increase the likelihood of mental health disorders. This study investigated the relationship between characteristics of external built residential environment and mental health disorders in selected residences of Nakuru Municipality, Kenya. External built residential environment characteristics were investigated for 544 residents living in different residential areas that were categorized by their socioeconomic status. Medically validated interview schedules were used to determine mental health of residents in the respective neighborhoods. The relationship between characteristics of the external built residential environment and mental health of residents was determined by multivariable logistic regression analyses and chi-square tests. The results show that walling materials used on buildings, density of dwelling units, state of street lighting, types of doors, states of roofs, and states of windows are some built external residential environment characteristics that affect mental health of adult males and females. Urban residential areas that are characterized by poor quality external built environment substantially expose the population to daily stressors and inconveniences that increase the likelihood of developing mental health disorders.

Preparing for climate change impacts in Norway's built environment

2003-01-01

This paper provides an overview of the Norwegian climate policy and of the practical implications of preparing Norway for climate change, with special emphasis on the challenges confronting the built environment. Although the Norwegian government has been relatively proactive in instituting measures aimed at halting global climate change, less attention has been paid to the challenge of adapting to climate change. The global climate system is likely to undergo changes, regardless of the implementation of abatement policies under the Kyoto Protocol or other regimes. The full range of impacts resulting from these changes is still uncertain; however, it is becoming increasingly clear that adaptation to climate change is necessary and inevitable within several sectors. The potential impacts of climate change in the built environment are now being addressed. Both the functionality of the existing built environment and the design of future buildings are likely to be altered by climate change impacts, and the expected implications of these new conditions are now investigated. However, measures aimed at adjustments within individual sectors, such as altering the criteria and codes of practice for the design and construction of buildings, constitute only a partial adaptation to climate change. In order to adapt effectively, larger societal and intersectoral adjustments are necessary. (author)

Disused Religious Space: Youth Participation in Built Heritage Regeneration

Directory of Open Access Journals (Sweden)

Karen Davison

2017-06-01

Full Text Available The rights of young people to participate in decision-making processes that affect their lives has been encouraged since the United Nations Convention on the Rights of the Child (1989. Since then, policy-makers and planners have started to consider the views of youth, especially those aged 11–17. The size of the youth population and their feelings of social isolation are two important reasons to include them in the decision-making that affects their local built environment. Little is known about youth opinions of the built environment and in particular disused religious buildings which can become a significant part of local cultural heritage. This paper explores youth perceptions, place attachment and influence on identity of a prominent disused local Methodist church in the City of Belfast. The paper details the expressive methodological approach designed to encourage youth participation in the regeneration scheme. The findings of the study showcase the valuable connections that can be made between youth and heritage religious buildings through education programmes. The project conclusions also highlight the benefits to be gained from engaging youth in local built heritage and will be of interest to those involved in the design, planning and redevelopment processes.

Built environmental correlates of physical activity in China: A review.

Science.gov (United States)

Day, Kristen

2016-06-01

China faces growing levels of physical inactivity and obesity, associated with increasing urbanization and changing lifestyles in recent years. China is expanding its cities to accommodate a growing urban population. This paper identifies built environment factors that are associated with physical activity in China. Findings can inform urban design and development in China to support increased physical activity. This paper is modeled on a review of built environment correlates of walking by Saelens and Handy (2008). Saelens and Handy reviewed research in developed countries. The present paper reviews 42 empirical studies that were conducted in China and were published between 2006 and 2014. Results discuss the association of built environment features and physical activity for transportation, recreation and work. Studies focus on adults and on major cities. Data on the built environment is typically self-reported. Strongest evidence was found for the positive association of physical activity with proximal non-residential locations, pedestrian infrastructure, aesthetics, and non-park physical activity facilities, and for the negative association of physical activity with urban residence. In terms of physical activity for transportation, evidence is strongest for associations between physical activity for transportation and proximal non-residential locations. More research is needed on the built environment and physical activity, especially including research on significant features of Chinese cities, such as air pollution, high density levels, traffic safety, and others. Research on associations between built environment features and physical activity should consider the specific social and built environment contexts of Chinese cities.

Good instructors know that lessons and courses change over time. Limitations in time and data often prevent instructors from making changes that will most benefit their students. For example, in traditional in-person classrooms an instructor may only have access to the final product of a student's thought processes (such as a term paper, homework assignment, or exam). The thought processes that lead to a given answer are opaque to the instructor, making future modifications to course content an exercise in trial-and-error and instinct. Modern online intelligent tutoring systems can provide insight into a student's behavior, providing transparency to a previously opaque process and providing the instructor with better information for course modification. Habitable Worlds is an introductory level online-only astrobiology lab course that has been offered at Arizona State University since Fall 2011. The course is built and offered through an intelligent tutoring system, Smart Sparrow's Adaptive eLearning Platform, which provides in-depth analytics that allow the instructor to investigate detailed student behavior, from time spent on question to number of attempts to patterns of answers. We will detail the process we employ of informed modification of course content, including time and trial comparisons between semesters, analysis of submitted answers, analysis of alternative learning pathways taken, and A/B testing.

Mobility, Mood and Place—Co-Designing Age-Friendly Cities: A Report on Collaborations between Older People and Students of Architecture

Directory of Open Access Journals (Sweden)

Iain Scott

2017-08-01

Full Text Available Mobility, Mood and Place explores how places can be designed collaboratively to make pedestrian mobility easy, enjoyable and meaningful for older people. The built environment often excludes marginalised groups such as older people, single mothers and others with special needs. ‘Co-design’ is emerging as an important approach in architectural and urban design, which diversifies stakeholder participation and representation. Participatory co-design approaches can include such stakeholders so as to address their priorities and ensure that other stakeholders empathise with their perspective. This can enhance students’ methodological flexibility and empathy. This paper critically reflects on architecture students’ experiences, together with older adults (including stroke-survivors and those with dementia, in producing co-design research on age-friendly environments and offers some methodological insights. It also discusses competing objectives between a co-design research project that involved students of architecture and landscape design on post-graduate academic programmes. Finally, the paper will offer contributions to architects interested in designing places that take into account the needs of older people.

EDITORIAL: BUILT ENVIRONMENT PERSPECTIVES ON POST-DISASTER RECONSTRUCTION

Directory of Open Access Journals (Sweden)

Jason von Meding

2013-11-01

It is with great pleasure that we would like to introduce this special issue of IJAR, a compilation of cutting-edge research that covers many of the key themes relevant to built environment researchers in disaster-related areas. This knowledge area is by its very nature absolutely multidisciplinary and for this reason it is difficult to quantify built environment impacts, drivers and outcomes in isolation and disaggregate them from non-built environment factors. However, regardless of certain limitations to research carried out from a built environment perspective, as would be the case from any specific disciplinary perspective, a significant body of work has emerged and is constantly growing and evolving in parallel with the research agenda. Built environment researchers around the globe are now, more than ever, exploring various problems that threaten humanity in the way of dire vulnerability and more frequent and powerful hazards. This collection of papers will look specifically at one area of disaster management, postdisaster reconstruction. Reconstruction projects primarily occur during the recovery phase of the disaster cycle, playing a key role in bringing vulnerable communities back to normalcy, integrating disaster risk reduction and preparedness measures to increase resilience to future hazard events. The special issue is broken into four thematic areas; Context and Culture, Theory, Resilience and Risk Reduction and Design. The three papers in Section 1- Context and Culture deal with the impacts of disasters on places and the people that inhabit them, investigating the extent to which reconstruction projects can address social and cultural problems. Meanwhile, the two papers in Section 2- Theory put forward new theoretical perspectives with regards to stakeholder engagement and management, representing the growth of alternative points of departure in this area. The three papers in Section 3- Resilience and Risk Reduction explore various approaches to

BRINGING THE CLASSROOM INTO THE WORLD: THREE AUSTRALIAN CASES OF DESIGNING MOBILE TECHNOLOGY TO SUPPORT BLENDED LEARNING FOR THE BUILT AND LANDSCAPED ENVIRONMENT

Directory of Open Access Journals (Sweden)

Wally Michael Smith

2017-01-01

Full Text Available We describe and reflect on three case studies of developing fieldwork for tertiary students of architectural history, landscape history and urban design. In each case, the potential of blended learning was explored through the use of mobile technology to explore designated sites as extensions of class-based learning. Two studies involved the development of apps that worked as guides for students to explore places of significance in Melbourne, while one study invited students to develop a design for a mobile app that could communicate the influence of urban design thinkers on a particular place in Sydney. We describe how these three exercises provide insights into the way that mobile technology, both real and imagined, can provide a conduit between classroom and field learning. Equally significant, we reflect on how the process of designing the apps became one of extended co-creation between student, tutors and teaching staff, also with consequence for learning.

The impact of user centered design on student motivation

Science.gov (United States)

Locker, Craig T.

There is a current push for STEM education within the U.S.; however current studies show that students' interest to pursue STEM fields is decreasing as they progress through high school. This lose in interest has shown to have a strong tie to students' perceived levels of motivation towards the subject. The question that this studied set out to answer was if user centered design (UCD) would affect students perceived level of motivation. For this study a treatment of UCD was compared to a traditional high school engineering design curriculum, with the goal to identify if UCD would have a positive effect on the students perceived level of motivation. 59 9th grade high school students from an urban Midwestern city were selected to participate. Students were given a pre and posttest to determine their levels of motivation before and after the comparison or treatment. Analysis showed that students perceived level of intrinsic and extrinsic motivation significantly went up in the treatment group. The study concluded that due to the ease of implementation and low cost of deployment that UCD should be introduced into high school design challenges that focus on developing a solution for an external stakeholder.

2012-10-01

Full Text Available Abstract Background A growing corpus of research focuses on assessing the quality of the local built environment and also examining the relationship between the built environment and health outcomes and indicators in communities. However, there is a lack of research presenting a highly resolved, systematic, and comprehensive spatial approach to assessing the built environment over a large geographic extent. In this paper, we contribute to the built environment literature by describing a tool used to assess the residential built environment at the tax parcel-level, as well as a methodology for summarizing the data into meaningful indices for linkages with health data. Methods A database containing residential built environment variables was constructed using the existing body of literature, as well as input from local community partners. During the summer of 2008, a team of trained assessors conducted an on-foot, curb-side assessment of approximately 17,000 tax parcels in Durham, North Carolina, evaluating the built environment on over 80 variables using handheld Global Positioning System (GPS devices. The exercise was repeated again in the summer of 2011 over a larger geographic area that included roughly 30,700 tax parcels; summary data presented here are from the 2008 assessment. Results Built environment data were combined with Durham crime data and tax assessor data in order to construct seven built environment indices. These indices were aggregated to US Census blocks, as well as to primary adjacency communities (PACs and secondary adjacency communities (SACs which better described the larger neighborhood context experienced by local residents. Results were disseminated to community members, public health professionals, and government officials. Conclusions The assessment tool described is both easily-replicable and comprehensive in design.

Karelina, Anna; Etkina, Eugenia

2007-12-01

National studies of science education have unanimously concluded that preparing our students for the demands of the 21st century workplace is one of the major goals. This paper describes a study of student activities in introductory college physics labs, which were designed to help students acquire abilities that are valuable in the workplace. In these labs [called Investigative Science Learning Environment (ISLE) labs], students design their own experiments. Our previous studies have shown that students in these labs acquire scientific abilities such as the ability to design an experiment to solve a problem, the ability to collect and analyze data, the ability to evaluate assumptions and uncertainties, and the ability to communicate. These studies mostly concentrated on analyzing students’ writing, evaluated by specially designed scientific ability rubrics. Recently, we started to study whether the ISLE labs make students not only write like scientists but also engage in discussions and act like scientists while doing the labs. For example, do students plan an experiment, validate assumptions, evaluate results, and revise the experiment if necessary? A brief report of some of our findings that came from monitoring students’ activity during ISLE and nondesign labs was presented in the Physics Education Research Conference Proceedings. We found differences in student behavior and discussions that indicated that ISLE labs do in fact encourage a scientistlike approach to experimental design and promote high-quality discussions. This paper presents a full description of the study.

Camila Pegoraro

2011-12-01

Full Text Available Due to the known difficulties on managing the design process of built environments, researchers and entrepreneurs have continuously developed and implemented best practices from areas such as Project Management (PM. However, there are still gaps to be filled, such as difficulties on monitoring the stakeholder’s requirements and their dynamics. In attempt to eliminate this gap, this paper aims to analyze if requirements management (RM can be integrated to PM and which are the main advantages and disadvantages of this integration. The research includes a literature review which presents PM and RM concepts, the last one based on software engineering approach. Moreover, a case study was performed in a construction company, using semi-structured interviews. The research showed that the use of RM is advantageous, even not solving all the projects difficulties, and that the proper structuring of the projects is a condition for the success of RM implementation. The main contribution is a generic and systematic proposal for integrating the stages of the RM to the projects.

Preparing for Distance Learning: Designing An Online Student Orientation Course

Directory of Open Access Journals (Sweden)

Diane D. Chapman

2004-01-01

Full Text Available This paper describes the analysis undertaken to design a 1-credit-hour online orientation course for students new to online learning. An instructional design team, as a part of an advanced instructional design course, worked with a university-based client. The client identified specific problem areas encountered by novice students of online courses and the team designed a comprehensive program to meet those needs. Analysis of the data revealed surprising differences in expectations between instructors of online courses and their students of what an orientation to online learning should include. The team also conducted a task analysis to aid in further identifying the skills, knowledge and attitudes required by students for success in online courses. Findings indicated that there is a need for online learners to understand the time commitment required of an online course and possess or develop strong time management skills. Because of small sample size, results cannot be generalized beyond the respondents. The authors found a mismatch in the perception of instructor technical skills versus student technical skill. Based on their findings, the paper provides recommendations on the appropriate design, development and implementation of an orientation to online learning.

This paper describes a series of student projects which are intended to complement theoretical education in acoustics and engineering noise control with practical experience. The projects are also intended to enhance the students' ability to work in a team, to manage a project, and to present their results. The projects are carried out in close cooperation with industrial partners so that the students can get a taste of the professional life of noise control engineers. The organization of such a project, its execution, and some of the results from the most recent student project are presented as a demonstrative example. This latest project involved the creation of noise maps of a production hall, the acoustic analysis of a packaging machine, and the acoustic analysis of a spiral vibratory conveyor. Upon completion of the analysis, students then designed, applied, and verified some simple preliminary noise reduction measures to demonstrate the potential of these techniques. © 2012 Acoustical Society of America

Built environment and diabetes

Development of type 2 diabetes mellitus is influenced by built environment, which is, ‘the environments that are modified by humans, including homes, schools, workplaces, highways, urban sprawls, accessibility to amenities, leisure, and pollution.’ Built environment contributes to diabetes through access to physical activity and through stress, by affecting the sleep cycle. With globalization, there is a possibility that western environmental models may be replicated in developing countries such as India, where the underlying genetic predisposition makes them particularly susceptible to diabetes. Here we review published information on the relationship between built environment and diabetes, so that appropriate modifications can be incorporated to reduce the risk of developing diabetes mellitus.

Eliciting and characterizing students' mental models within the context of engineering design

Science.gov (United States)

Dankenbring, Chelsey

Recently, science education reform documents have called for the incorporation of engineering principles and practices into the K-12 science standards and curriculum. One way this has been done is through the use of engineering design tasks as a way for students to apply their scientific understandings to real-world problems. However, minimal studies have documented students' conceptions within the context of engineering design. Thus, the first chapter of this thesis outlines the steps taken to develop a draw-and-explain item that elicited students' mental models regarding the cause of the four seasons after finishing an engineering design task. Students' mental models regarding the reason for the seasons are also described. The second chapter characterizes students' conceptions regarding sun-Earth relationships, specifically the amount of daylight hours throughout the year, for students who completed either an engineering design task or more traditional learning activities. Results from these studies indicate that draw-and-explain items are an effective way of obtaining students' mental models and that students harbor a variety of alternate conceptions on astronomy related concepts within various learning contexts. Implications from this study include the need for further research regarding how engineering design is used in the classroom and how engineering design facilitates science learning. Also, professional development that allows in-service teachers to gain experience teaching engineering design is needed, as are teacher preparation programs that expose pre-service teachers to engineering design.

Student-Designed Service-Learning Projects in an Undergraduate Neurobiology Course

Directory of Open Access Journals (Sweden)

Katharine V. Northcutt

2015-12-01

Full Text Available One of the challenges in teaching a service-learning course is obtaining student buy-in from all students in the course. To circumvent this problem, I have let students in my undergraduate Neurobiology course design their own service-learning projects at the beginning of the semester. Although this can be chaotic because it requires last-minute planning, I have made it successful through facilitating student communication in the classroom, requiring thorough project proposals, meeting with students regularly, and monitoring group progress through written reflection papers. Most of my students have strong opinions about the types of projects that they want to carry out, and many students have used connections that they have already made with local organizations. Almost all projects that students have designed to this point involve teaching basic concepts of neurobiology to children of various ages while simultaneously sparking their interest in science. Through taking ownership of the project and designing it such that it works well with their strengths, interests, and weekly schedule, students have become more engaged in service learning and view it as a valuable experience. Despite some class time being shifted away from more traditional assignments, students have performed equally well in the course, and they are more eager to talk with others about course concepts. Furthermore, the feedback that I have received from community partners has been excellent, and some students have maintained their work with the organizations.

2017-12-01

Every summer for the past 26 years the University of New Hampshire (UNH) has run a month-long, residential outreach program for high school students considering careers in mathematics, science, or engineering. Space science is one of the modules. Students work directly with UNH faculty performing original work with real spacecraft data and hardware and present the results of that effort at the end of the program. This year the student research projects used data from the Messenger, STEREO, and Triana missions. In addition, the students build and fly a high-altitude balloon payload with instruments of their own construction. Students learn circuit design and construction, microcontroller programming, and core atmospheric and space science along with fundamental concepts in space physics and engineering. Our payload design has evolved significantly since the first flight of a simple rectangular box and now involves a stable descent vehicle that does not require a parachute. Our flight hardware includes an on-board flight control computer, in-flight autonomous control and data acquisition of multiple student-built instruments, and real-time camera images sent to ground. This year we developed, built and flew a successful line cutter based on GPS location information that prevents our payload from falling into the ocean while also separating the payload from the balloon remains for a cleaner descent. We will describe that new line cutter design and implementation along with the shielded Geiger counters that we flew as part of our cosmic ray air shower experiment. This is a program that can be used as a model for other schools to follow and that high schools can initiate. More information can be found at .

Using Green Building As A Model For Making Health Promotion Standard In The Built Environment.

Science.gov (United States)

Trowbridge, Matthew J; Worden, Kelly; Pyke, Christopher

2016-11-01

The built environment-the constructed physical parts of the places where people live and work-is a powerful determinant of both individual and population health. Awareness of the link between place and health is growing within the public health sector and among built environment decision makers working in design, construction, policy, and both public and private finance. However, these decision makers lack the knowledge, tools, and capacity to ensure that health and well-being are routinely considered across all sectors of the built environment. The green building industry has successfully established environmental sustainability as a normative part of built environment practice, policy making, and investment. We explore the value of this industry's experience as a template for promoting health and well-being in the built environment. Project HOPE—The People-to-People Health Foundation, Inc.

2013-01-01

Variety of online tools were built to help assessing students' performance in school. Many teachers changed their methods of assessment from paper-and-pencil (P&P) to online systems. In this study we analyse the influence that using an online system for knowledge assessment has on students' knowledge. Based on both a literature study and our own research we designed and built an online system for knowledge assessment. The system is evaluated using two groups of primary school teachers and students (N = 686) in Slovenia: an experimental and a control group. Students solved P&P exams on several occasions. The experimental group was allowed to access the system either at school or at home for a limited period during the presentation of a selected school topic. Students in the experimental group were able to solve tasks and compare their own achievements with those of their coevals. A comparison of the P&P school exams results achieved by both groups revealed a positive effect on subject topic comprehension for those with access to the online self-assessment system.

The computing education in Taiwan's vocational schools usually focuses on how to help students enhance their professional skills and pass certified examinations. In addition, due to national education policy and universities' regulations, pure online courses are not permitted in Taiwan. In order to design appropriate blended learning (BL) courses, the author explored the effects of web-mediated self-regulated learning (SRL) with variations in online class frequency on enhancing students' computing skills and their perspective of the blended courses. A total of 172 students, divided into four groups, participated in the experiment. The results showed that students in the SRL and BL group with five online classes had the highest scores for using a database management system (DBMS), and the highest pass rate on certified examinations. Students in this group also expressed their positive perspective on the arrangement of their blended course with the intervention of web-mediated SRL.

A Systems Engineering Methodology for Designing and Planning the Built Environment—Results from the Urban Research Laboratory Nuremberg and Their Integration in Education

Directory of Open Access Journals (Sweden)

Philipp Geyer

2014-04-01

Full Text Available Sustainable urban development requires a long-term sector-integrative approach. This paper proposes a method of system analysis and partial simulation for urban structures for this purpose. It couples a discussion-based holistic approach for systems analysis and modelling of urban structures with quantitative modelling and simulation of partial scenarios that serve to examine specific questions regarding the long-term development of urban structures. In the first part, the application in the City Lab Nuremberg West, a multidisciplinary urban research laboratory, serves to develop the methodology and its illustration. The main objective is to examine the transition of the existing underperforming quarter to a sustainable and livable urban environment. Scenario-based experiments with respect to development paths determine robustness and risks of different configurations. The second part of the paper describes the transfer of the methodology to education. The approach serves to teach students in the Energy-Efficient and Sustainable Building master course program an integrative way of planning a sustainable built environment. The definition of educational objectives concerning the students’ understanding and management of systemic interdependencies of sustainability help assess the use of the method in the classroom. The aim is to provide them with the competence to develop strategies for complex situations while planning a sustainable built environment.

Douglas, R Duane; Hopp, Christa D; Augustin, Marcus A

2014-12-01

The purpose of this study was to evaluate dental students' perceptions of traditional waxing vs. computer-aided crown design and to determine the effectiveness of either technique through comparative grading of the final products. On one of twoidentical tooth preparations, second-year students at one dental school fabricated a wax pattern for a full contour crown; on the second tooth preparation, the same students designed and fabricated an all-ceramic crown using computer-aided design (CAD) and computer-aided manufacturing (CAM) technology. Projects were graded for occlusion and anatomic form by three faculty members. On completion of the projects, 100 percent of the students (n=50) completed an eight-question, five-point Likert scalesurvey, designed to assess their perceptions of and learning associated with the two design techniques. The average grades for the crown design projects were 78.3 (CAD) and 79.1 (wax design). The mean numbers of occlusal contacts were 3.8 (CAD) and 2.9(wax design), which was significantly higher for CAD (p=0.02). The survey results indicated that students enjoyed designing afull contour crown using CAD as compared to using conventional wax techniques and spent less time designing the crown using CAD. From a learning perspective, students felt that they learned more about position and the size/strength of occlusal contacts using CAD. However, students recognized that CAD technology has limits in terms of representing anatomic contours and excursive occlusion compared to conventional wax techniques. The results suggest that crown design using CAD could be considered as an adjunct to conventional wax-added techniques in preclinical fixed prosthodontic curricula.

Consolidity: Moving opposite to built-as-usual systems practices

Hassen Taher Dorrah

2013-06-01

Full Text Available With the recent uncovering of the mystery of consolidity as an inner property of systems, it is demonstrated that this notion is an indispensable pillar of systems modeling, analysis, design and building. Based on the opposite mathematical relation between consolidity versus stability and controllability, a new conceptual life cycle (change pathway graph for natural and man-made built-as-usual systems is presented and thoroughly discussed. For the conceptual cycle development progress, it is logically conceived that system behavior changes rate has not accidentally happened, but is relatively influenced at the point of progress by the associated direct system consolidity index corresponding to the acting on-the-spot varying environments or effects. Such conceptual graph represents a real research advancement indicating that we have to move opposite to current systems building practices for solving many real life enigmatic problems. It is illustrated using stabilization of inverted pendulum problem that it is amenable by cleverly manipulating systems structure and parameters to attain new designed systems with aggregates of superiority of consolidity, stability and controllability principle. It is recommended that we have to seek new generation of innovative non-conventional systems structures moving opposite to conventional built-as-usual system practices that can enable providing directly such three aggregates of superiority requirements as their built-in self property. This will open the door towards solving many real life challenging dilemmas in various sciences and disciplines, such as engineering, space sciences, medicine, pharmacology, biology, ecology, life sciences, economy, operations research, humanities and social sciences that are believed to be attributed due to their systems inferior consolidity.

Vergel, John; Quintero, Gustavo A; Isaza-Restrepo, Andrés; Ortiz-Fonseca, Martha; Latorre-Santos, Catalina; Pardo-Oviedo, Juan Mauricio

2018-12-01

The relationship between students' withdrawal and educational variables has generated a considerable number of publications. As the explosion of information in sciences and integration theories led to creating different curriculum designs, it has been assumed that differences among designs explain academic success and, therefore, students' retention. However, little attention has been given to examine explicitly how diverse designs influence dropout rates in practice, which questions if decisions to reform curricula are sufficiently informed. This article describes our curriculum reform, which exposes our former and current curriculum designs as having had dissimilar dropout percentages. Furthermore, we aimed to explore the influence of different curriculum designs on students' dropout rates. The conclusion is that dropout variations may be explained not only because of the curriculum design itself, but also because of the power relationship changes between teachers and students that brought out the design change. Consequently, more research is needed to fully understand the political implications of different curriculum designs and their influence on dropout rates.

Influence of core design, production technique, and material selection on fracture behavior of yttria-stabilized tetragonal zirconia polycrystal fixed dental prostheses produced using different multilayer techniques: split-file, over-pressing, and manually built-up veneers.

To investigate and compare the fracture strength and fracture mode in eleven groups of currently, the most commonly used multilayer three-unit all-ceramic yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) fixed dental prostheses (FDPs) with respect to the choice of core material, veneering material area, manufacturing technique, design of connectors, and radii of curvature of FDP cores. A total of 110 three-unit Y-TZP FDP cores with one intermediate pontic were made. The FDP cores in groups 1-7 were made with a split-file design, veneered with manually built-up porcelain, computer-aided design-on veneers, and over-pressed veneers. Groups 8-11 consisted of FDPs with a state-of-the-art design, veneered with manually built-up porcelain. All the FDP cores were subjected to simulated aging and finally loaded to fracture. There was a significant difference (Pdesigns, but not between the different types of Y-TZP materials. The split-file designs with VITABLOCS(®) (1,806±165 N) and e.max(®) ZirPress (1,854±115 N) and the state-of-the-art design with VITA VM(®) 9 (1,849±150 N) demonstrated the highest mean fracture values. The shape of a split-file designed all-ceramic reconstruction calls for a different dimension protocol, compared to traditionally shaped ones, as the split-file design leads to sharp approximal indentations acting as fractural impressions, thus decreasing the overall strength. The design of a framework is a crucial factor for the load bearing capacity of an all-ceramic FDP. The state-of-the-art design is preferable since the split-file designed cores call for a cross-sectional connector area at least 42% larger, to have the same load bearing capacity as the state-of-the-art designed cores. All veneering materials and techniques tested in the study, split-file, over-press, built-up porcelains, and glass-ceramics are, with a great safety margin, sufficient for clinical use both anteriorly and posteriorly. Analysis of the fracture pattern shows

Greening the built environment

Smith, Maf; Whitelegg, John; Williams, Nick J.

1998-07-15

The built environment incorporates our homes, our workplaces and places of leisure. Under the influence of a complex web of social and economic processes, it is where many issues of human and environmental well-being come to a head - whether of space, mobility, energy consumption, pollution, health or security. All too often, concerns such as cost are put before the things we value for a fulfilling life, including peace and quiet and health and happiness. Getting the built environment right is fundamental to a sustainable society and requires an integrated approach. This important new book, published in association with the World Wide Fund For Nature (WWF-UK), provides us with a firm understanding of the interrelationships of many of the issues and problems of the built environment and describes the holistic models of development, management and planning necessary for urban sustainability. It draws attention to the major challenges and policy implications and offers analysis, approaches and vision for moving towards sustainable towns and cities that in turn will facilitate sustainable lifestyles.

The impact of exposure to films of natural and built environments on state body appreciation.

Science.gov (United States)

Swami, Viren; Pickering, Mark; Barron, David; Patel, Shreepali

2018-06-12

Previous work has shown that exposure to images of nature results in elevated state body appreciation, but static images may lack ecological validity. Here, we examined the impact of exposure to short films of simulated, first-person walks in natural or built environments. Thirty-six university students completed a measure of state body appreciation before and after watching films of either a walk in a natural or a built environment created specifically for the present study. Two weeks later, they completed the same task but watched the other film type. Results indicated that exposure to the film of a natural environment resulted in significantly elevated state body appreciation (d = 0.66). There was no significant change in state body appreciation following exposure to the film of the built environment (d = 0.14). These findings suggest that exposure to films depicting the natural environment may promote immediate, moderate-sized improvements in state body image. Copyright © 2018 Elsevier Ltd.

The networked student: A design-based research case study of student constructed personal learning environments in a middle school science course

Science.gov (United States)

Drexler, Wendy

This design-based research case study applied a networked learning approach to a seventh grade science class at a public school in the southeastern United States. Students adapted emerging Web applications to construct personal learning environments for in-depth scientific inquiry of poisonous and venomous life forms. The personal learning environments constructed used Application Programming Interface (API) widgets to access, organize, and synthesize content from a number of educational Internet resources and social network connections. This study examined the nature of personal learning environments; the processes students go through during construction, and patterns that emerged. The project was documented from both an instructional and student-design perspective. Findings revealed that students applied the processes of: practicing digital responsibility; practicing digital literacy; organizing content; collaborating and socializing; and synthesizing and creating. These processes informed a model of the networked student that will serve as a framework for future instructional designs. A networked learning approach that incorporates these processes into future designs has implications for student learning, teacher roles, professional development, administrative policies, and delivery. This work is significant in that it shifts the focus from technology innovations based on tools to student empowerment based on the processes required to support learning. It affirms the need for greater attention to digital literacy and responsibility in K12 schools as well as consideration for those skills students will need to achieve success in the 21st century. The design-based research case study provides a set of design principles for teachers to follow when facilitating student construction of personal learning environments.

Designing learning environments to promote student learning: ergonomics in all but name.

Science.gov (United States)

Smith, Thomas J

2013-01-01

This report introduces evidence for the conclusion that a common theme underlies almost all proposed solutions for improving the performance of K-12 students, namely their reliance on the design of educational system environments, features and operations. Two categories of design factors impacting such performance are addressed: (1) 9 factors reliably shown to have a strong influence - namely environmental design of classroom and building facilities, longer exposure to learning, cooperative learning designs, early childhood education, teaching quality, nutritional adequacy, participation in physical activity, good physical fitness, and school-community integration; and (2) 11 factors with an equivocal, varied or weak influence - classroom technology, online learning environments, smaller class size, school choice, school funding, school size, school start times, teacher training level, amount of homework, student self-confidence and informal learning. It is concluded that: (1) student learning outcomes, and more broadly the edifice of education itself, are largely defined in terms of an extensive system of design factors and conditions; (2) the time is long overdue for the educational system to acknowledge the central role of E/HF design as the major influence on student performance and learning; and (3) K-12 educators and administrators should emphasize allocation of resources to design factors reliably shown to have a strongly positive impact on student performance, but should treat expenditure on factors with equivocal, varied or weak influence on such performance with more caution and/or skepticism.

In order to fully exploit Doublet III capabilities and to study new plasma physics regimes, a Neutral Beam Injector System has been constructed. Initially, a two beamline system will supply 7 MW of heat to the plasma. The system is currently being expanded to inject approx. 20 MW of power (6 beamlines). Each beamline is equipped with two Lawrence Berkeley Laboratory type rectangular ion sources with 10 cm x 40 cm extraction grids. These sources will accelerate hydrogen ions to 80 keV, with extracted beam currents in excess of 80 A per source expected. The first completed source is currently being tested and conditioned on the High Voltage Test Stand at Lawrence Livermore Laboratory. This paper pictorially reviews the as-built Doublet III neutral beamline with emphasis on component relation and configuration relative to spatial and source imposed design constraints

Tan, Lindsay; Hong, Miyoung; Albert, Taneshia West

2017-10-01

This case study explores the influence of the healthcare design studio experience on students' short-term professional goals as measured through rates of healthcare-related certification and internship/employment. The value and relevance of interior design is evident in the healthcare design sector. However, interior design students may not perceive this value if it is not communicated through their design education. Students' experience in the design studio plays a crucial role in determining career choices, and students may be more committed to career goals when there is clear connection between major coursework and professional practice. The authors compared healthcare-related certification and internship/employment levels between two student cohorts in a capstone undergraduate interior design healthcare design studio course. The first cohort was led by the existing curriculum. The second cohort was led by the revised curriculum that specifically aimed at encouraging students to commit to healthcare-related design practice. When measured at 3 months from graduation, the second cohort, led by the revised curriculum, saw a 30% increase in Evidence-based Design Accreditation and Certification exam pass rates and a 40% increase in healthcare-related internship/employment. The challenge of interior design education is to instill in emerging professionals not only professional competence but also those professional attitudes that will make them better prepared to design spaces that improve quality of life, particularly in healthcare environments. The results exceeded the project goals, and so this could be considered a promising practice for courses focused on healthcare design education.

Silicon-on-Insulator Lateral-Insulated-Gate-Bipolar-Transistor with Built-in Self-anti-ESD Diode

Directory of Open Access Journals (Sweden)

2014-05-01

Full Text Available Power SOI (Silicon-On-Insulator devices have an inherent sandwich structure of MOS (Metal-Oxide-Semiconductor gate which is very easy to suffer ESD (Electro-Static Discharge overstress. To solve this reliability problem, studies on design and modification of a built-in self-anti-ESD diode for a preliminarily optimized high voltage SOI LIGBT (Lateral-Insulated-Gate-Bipolar-Transistor were carried out on the Silvaco TCAD (Technology-Computer-Aided-Design platform. According to the constrains of the technological process, the new introduction of the N+ doped region into P-well region that form the built-in self-anti-ESD diode should be done together with the doping of source under the same mask. The modifications were done by adjusting the vertical impurity profile in P-well into retrograde distribution and designing a cathode plate with a proper length to cover the forward depletion terminal and make sure that the thickness of the cathode plate is the same as that of the gate plate. The simulation results indicate that the modified device structure is compatible with the original one in process and design, the breakdown voltage margin of the former was expanded properly, and both the transient cathode voltages are clamped low enough very quickly. Therefore, the design and optimization results of the modified device structure of the built-in self-anti-ESD diode for the given SOI LIGBT meet the given requirements.

Taleyarkhan, Manaz; Dasgupta, Chandan; Garcia, John Mendoza; Magana, Alejandra J.

2018-02-01

Engineering design thinking is hard to teach and still harder to learn by novices primarily due to the undetermined nature of engineering problems that often results in multiple solutions. In this paper, we investigate the effect of teaching engineering design thinking to freshmen students by using a computer-aided Design (CAD) simulation software. We present a framework for characterizing different levels of engineering design thinking displayed by students who interacted with the CAD simulation software in the context of a collaborative assignment. This framework describes the presence of four levels of engineering design thinking—beginning designer, adept beginning designer, informed designer, adept informed designer. We present the characteristics associated with each of these four levels as they pertain to four engineering design strategies that students pursued in this study—understanding the design challenge, building knowledge, weighing options and making tradeoffs, and reflecting on the process. Students demonstrated significant improvements in two strategies—understanding the design challenge and building knowledge. We discuss the affordances of the CAD simulation tool along with the learning environment that potentially helped students move towards Adept informed designers while pursuing these design strategies.

We carry out teaching based on optoelectronic related course group, aiming at junior students majored in Optoelectronic Information Science and Engineering. " Optoelectronic System Course Project " is product-designing-oriented and lasts for a whole semester. It provides a chance for students to experience the whole process of product designing, and improve their abilities to search literature, proof schemes, design and implement their schemes. In teaching process, each project topic is carefully selected and repeatedly refined to guarantee the projects with the knowledge integrity, engineering meanings and enjoyment. Moreover, we set up a top team with professional and experienced teachers, and build up learning community. Meanwhile, the communication between students and teachers as well as the interaction among students are taken seriously in order to improve their team-work ability and communicational skills. Therefore, students are not only able to have a chance to review the knowledge hierarchy of optics, electronics, and computer sciences, but also are able to improve their engineering mindset and innovation consciousness.

Smart built-in test for nuclear thermal propulsion

International Nuclear Information System (INIS)

Lombrozo, P.C.

1992-03-01

Smart built-in test (BIT) technologies are envisioned for nuclear thermal propulsion spacecraft components which undergo constant irradiation and are therefore unsafe for manual testing. Smart BIT systems of automated/remote type allow component and system tests to be conducted; failure detections are directly followed by reconfiguration of the components affected. The 'smartness' of the BIT system in question involves the reduction of sensor counts via the use of multifunction sensors, the use of components as integral sensors, and the use of system design techniques which allow the verification of system function beyond component connectivity

An important role for education is to inform and create the right skills for people to develop their own vision, using their talents to the utmost and inspire others to learn to explore in the future. Great effort has been taken to prepare this interactive design workshop thoroughly. Three days in a row, starting with presentations of Artscience The Hague to ESA colleagues, followed by a Planetary research Symposium in Amsterdam and a student design workshop at the end complemented a rich environment with the focus on Planetary exploration. The design workshop was organised by GeoVUsie students, with ESTEC and ILEWG support for tutors and inviting regional and international students to participate in an interactive workshop to design 5 Planetary Missions, with experts sharing their expertise and knowhow on specific challenging items: 1. Mercury - Post BepiColombo (with Sebastien Besse, ESA) 2. Moon South Pole Mission (with Bernard Foing, ESA) 3. Post-ExoMars - In search for Life on Mars (with Jorge Vago, ESA) 4. Humans in Space - Mars One investigated(with Arno Wielders, Space Horizon) 5. Europa - life on the icy moon of Jupiter? (with Bert Vermeersen, TU Delft. Lectures were given for more than 150 geology students at the symposium "Moon, Mars and More" at VU university, Amsterdam (organized by GeoVUsie earth science students). All students were provided with information before and at start for designing their mission. After the morning session there was a visit to the exhibition at The Erasmus Facility - ESTEC to inspire them even more with real artifacts of earlier and future missions into space. After this visit they prepared their final presentations, with original results, with innovative ideas and a good start to work out further in the future. A telescope session for geology students had been organized indoor due to rain. A follow-up visit to the nearby public Copernicus observatory was planned for another clear sky occasion.

2016-06-01

Full Text Available This paper examines the contributions of two British architects, Maxwell Fry and Jane Drew in the development of built environment in Nigeria after World War II. It analyses the historical development of the built environment in Nigeria’s public space with respect to modernize infrastructures such as banks, schools, teachers training colleges and the university needed in support of the colonial administration in Nigeria. The agitation of the nationalists and postwar reconstruction facilitated and encouraged the British Empire to develop the edifice or structures that would be suitable for the environment. This, to a large extent, influenced the Nigerian architecture and built environment. Their design principles yielded functional institutional spaces and a hybrid aesthetics that signifies modernist construction and colonial influence. The paper concludes that the designs of both Fry and Drew represent a milestone and significant contribution to the development of built environment in colonial Nigeria.

2013-01-01

Full Text Available In this work the design, fabrication and investigation of a solar biogas digester with built-in RAH (Reverse Absorber Heater is presented. The maximum temperature (50 o C inside of the methane tank was taken as a main parameter at the design of the digester. Using energy balance equation for the case of a static mass of fluid being heated; the parameters of thermal insulation of the methane tank were counted. The biogas digester is consisting of methane tank with built-in solar RAH to utilize solar energy for the heating of the slurry prepared from the different organic wastes (dung, sewage, food wastes etc. The methane tank was filled up to 70% of volume by organic wastes of the GIK Institute sewage, firstly, and secondly, by sewage and cow dung as well. During three months (October-December, 2009 and two months (February-March, 2010 the digester was investigated. The solar irradiance incident to the absorber, slurry's temperature and ambient temperature were measured. It was found that using sewage only and sewage with cow dung the retention times was 4 weeks and two weeks respectively and biogas quantity produced was 0.4 and 8.0 m 3 respectively. In addition, biogas upgradation scheme for removal of carbon dioxide, hydrogen sulphide and water vapor from biogas and conversion of biogas energy conversion into electric power is also discussed.

Context, built form and space: A case of public housing estates in Hong Kong

Directory of Open Access Journals (Sweden)

Rumana Afroz

2012-06-01

Full Text Available The context of public housing development in Hong Kong can be traced back to a deep rooted history when it was a need rather than a choice. At present, the public housing estates have become a much desired residential destination by the general people of Hong Kong although several changes in design have been observed that are not completely adapted by the residents. This study aims to investigate on the changing phenomenon of the context and the built form; and its impact on space in terms of adaptability by the residents. It has been found that, forced or formal communal spaces influenced by self-conscious culture discourage social interaction where quantitative measures are only applied, and informal communal spaces encouraged by unselfconscious culture bring happy social life. Contemporary built forms in the housing estates have changed a lot both externally and internally, and attention has been given to quantitative measures and formal spatial arrangements. As a result a gap is emerging between context, built form and adapted use of space. Therefore, measures such as qualitative approach, sensitively designed spatial arrangements are recommended to minimize the gap.

Influence of core design, production technique, and material selection on fracture behavior of yttria-stabilized tetragonal zirconia polycrystal fixed dental prostheses produced using different multilayer techniques: split-file, over-pressing, and manually built-up veneers

2016-02-01

Full Text Available Deyar Jallal Hadi Mahmood, Ewa H Linderoth, Ann Wennerberg, Per Vult Von Steyern Department of Prosthetic Dentistry, Faculty of Odontology, Malmö University, Malmö, Sweden Aim: To investigate and compare the fracture strength and fracture mode in eleven groups of currently, the most commonly used multilayer three-unit all-ceramic yttria-stabilized tetragonal zirconia polycrystal (Y-TZP fixed dental prostheses (FDPs with respect to the choice of core material, veneering material area, manufacturing technique, design of connectors, and radii of curvature of FDP cores. Materials and methods: A total of 110 three-unit Y-TZP FDP cores with one intermediate pontic were made. The FDP cores in groups 1–7 were made with a split-file design, veneered with manually built-up porcelain, computer-aided design-on veneers, and over-pressed veneers. Groups 8–11 consisted of FDPs with a state-of-the-art design, veneered with manually built-up porcelain. All the FDP cores were subjected to simulated aging and finally loaded to fracture. Results: There was a significant difference (P<0.05 between the core designs, but not between the different types of Y-TZP materials. The split-file designs with VITABLOCS® (1,806±165 N and e.max® ZirPress (1,854±115 N and the state-of-the-art design with VITA VM® 9 (1,849±150 N demonstrated the highest mean fracture values. Conclusion: The shape of a split-file designed all-ceramic reconstruction calls for a different dimension protocol, compared to traditionally shaped ones, as the split-file design leads to sharp approximal indentations acting as fractural impressions, thus decreasing the overall strength. The design of a framework is a crucial factor for the load bearing capacity of an all-ceramic FDP. The state-of-the-art design is preferable since the split-file designed cores call for a cross-sectional connector area at least 42% larger, to have the same load bearing capacity as the state-of-the-art designed

Impacts of Built-Up Area Expansion in 2D and 3D on Regional Surface Temperature

Directory of Open Access Journals (Sweden)

Hongyan Cai

2017-10-01

Full Text Available Many studies have reported the thermal effects of urban expansion from non-built-up land; however, how changes in building height in built-up land influence the regional thermal environment is still uncertain. Thus, taking the transitional region between the Chinese megacities of Beijing and Tianjin as the study area, this study investigated the impacts of built-up land expansion in 2D and 3D on regional land surface temperature (LST. The expansion in 2D refers to the conversion from non-built-up land to built-up land, whereas the expansion in 3D characterized the building height change in the built-up land, referring to the conversion from low- and moderate-rise building (LMRB to high-rise building (HRB lands. The land use change from 2010 to 2015 was manually interpreted from high spatial resolution SPOT5 and Gaofen2 images, and the LST information in the corresponding period was derived from Landsat5/8 thermal images using an image-based method. The results showed that between 2010 and 2015, approximately 87.25 km2 non-built-up land was transformed to built-up land, and 13.21 km2 LMRB land was built into HRB land. These two types of built-up land expansions have induced opposing thermal effects in regard to regional surface temperature. The built-up land expansions from cropland and urban green land have raised the regional LST. However, the built-up land expansion from LMRB to HRB lands has induced a cooling effect. Thus, this study suggested that for the cooling urban design, the building height should also be considered. Furthermore, for future studies on thermal impacts of urbanization, it should be cautioned that, besides the urban area expansion, the building height change should also be emphasized due to its potential cooling effects.

All my friends are here: Four initial case studies on student design agencies

Directory of Open Access Journals (Sweden)

Peter Benz

2013-10-01

Full Text Available Student design agencies have not previously received much – if any – academic attention, despite their having become fairly common in the context of tertiary design / visual arts institutions since the late 1990s as a way of providing work–study experiences. This article, for the first time, outlines case studies of four international student design agencies in Germany, Malaysia and the USA, including their background, their legal set-up, their relations with their parent institutions, and their (business activities and general operations, as well as their members’ motivations for participation. All case studies are based on interviews by email or Skype with respective agency heads conducted from November 2012 to January 2013. The information obtained from the interviews was further rounded by additional materials – where available – and turned into short comprehensive narratives that highlight the particular qualities of the respective cases. The concluding comparison of these four narratives establishes that student design agencies are worthwhile knowledge transfer endeavours with strong indications of educational value, though more formal research would need to be done to confirm quantitative and qualitative effects. The four cases also allow for the deduction that the most important criterion for the success of a student design agency is its ability to create an intensive working experience with a strong focus on team interaction, and that the achievement of such experience is essentially based on on-campus space, staff involvement, competitive admission and non-business-related activities. Keywords: student design agency, knowledge transfer, student entrepreneurs, entrepreneurship, business innovation

Approaching direct optimization of as-built lens performance

Science.gov (United States)

McGuire, James P.; Kuper, Thomas G.

2012-10-01

We describe a method approaching direct optimization of the rms wavefront error of a lens including tolerances. By including the effect of tolerances in the error function, the designer can choose to improve the as-built performance with a fixed set of tolerances and/or reduce the cost of production lenses with looser tolerances. The method relies on the speed of differential tolerance analysis and has recently become practical due to the combination of continuing increases in computer hardware speed and multiple core processing We illustrate the method's use on a Cooke triplet, a double Gauss, and two plastic mobile phone camera lenses.

Magneto-optical tweezers built around an inverted microscope

Claudet, Cyril; Bednar, Jan

2005-01-01

We present a simple experimental setup of magneto-optical tweezers built around an inverted microscope. Two pairs of coils placed around the focal point of the objective generate a planar-rotating magnetic field that is perpendicular to the stretching direction. This configuration allows us to control the rotary movement of a paramagnetic bead trapped in the optical tweezers. The mechanical design is universal and can be simply adapted to any inverted microscope and objective. The mechanical configuration permits the use of a rather large experimental cell and the simple assembly and disassembly of the magnetic attachment

Objective. To determine whether a flipped classroom design would improve student performance and perceptions of the learning experience compared to traditional lecture course design in a required pharmacotherapy course for second-year pharmacy students. Design. Students viewed short online videos about the foundational concepts and answered self-assessment questions prior to face-to-face sessions involving patient case discussions. Assessment. Pretest/posttest and precourse/postcourse surveys evaluated students' short-term knowledge retention and perceptions before and after the redesigned course. The final grades improved after the redesign. Mean scores on the posttest improved from the pretest. Postcourse survey showed 88% of students were satisfied with the redesign. Students reported that they appreciated the flexibility of video viewing and knowledge application during case discussions but some also struggled with time requirements of the course. Conclusion. The redesigned course improved student test performance and perceptions of the learning experience during the first year of implementation.

Solder bond requirement for large, built-up, high-performance conductors

International Nuclear Information System (INIS)

Willig, R.L.

1981-01-01

Some large built-up conductors fabricated for large superconducting magnets are designed to operate above the maximum recovery current. Because the stability of these conductors is sensitive to the quality of the solder bond joining the composite superconductor to the high-conductivity substrate, a minimum bond requirement is necessary. The present analysis finds that the superconductor is unstable and becomes abruptly resistive when there are temperature excursions into the current sharing region of a poorly bonded conductor. This abrupt transition, produces eddy current heating in the vicinity of the superconducting filaments and causes a sharp reduction in the minimum propagating zone (MPZ) energy. This sensitivity of the MPZ energy to the solder bond contact area is used to specify a minimum bond requirement. For the superconducting MHD magnet built for the Component Development Integration Facility (CDIF), the minimum bonded surface area is .68 cm/sup 2//cm which is 44% of the composite perimeter. 5 refs

Using historical perspective in designing discovery learning on Integral for undergraduate students

Science.gov (United States)

Abadi; Fiangga, S.

2018-01-01

In the course of Integral Calculus, to be able to calculate an integral of a given function is becoming the main idea in the teaching beside the ability in implementing the application of integral. The students tend to be unable to understand the conceptual idea of what is integration actually. One of the promising perspectives that can be used to invite students to discover the idea of integral is the History and Pedagogy Mathematics (HPM). The method of exhaustion and indivisible appear in the discussion on the early history of area measurement. This paper study will discuss the designed learning activities based on the method of exhaustion and indivisible in providing the undergraduate student’s discovery materials for integral using design research. The designed learning activities were conducted into design experiment that consists of three phases, i.e., preliminary, design experimental, and teaching experiment. The teaching experiment phase was conducted in two cycles for refinement purpose. The finding suggests that the implementation of the method of exhaustion and indivisible enable students to reinvent the idea of integral by using the concept of derivative.

Full Text Available This paper presents the findings from an undergraduate research project concerning the energy efficiency, consumption, and generation of a 1000 ft2 (92.9 m2 solar house. The results were compared to a home of similar size and layout, built using traditional construction methods. The solar house was modeled after the Chameleon House: Missouri University of Science and Technology’s 2013 entry in the U.S. Department of Energy Solar Decathlon. The efficiency of the design was analyzed using Energy-10 Version 1.8 software. For this comparison, a fictional American couple was created and a breakdown of their energy-use habits was recorded to accurately depict the magnitude of energy consumption. A 71% energy savings was forecasted using the Energy-10 software through the incorporation of various energy-conserving strategies in the home’s design. In addition, if a 9.1 kW photovoltaic array is also installed on a home of this size, it is possible to fully offset the energy consumption of the home. The forecasted energy usage and production detailed in this report shall be used for analyzing the integrity of the design of the Chameleon House as well as future solar houses constructed by the Missouri S&T Solar House Team.

Visualizing Oceans of Data: Using learning research to inform the design of student interfaces to climate data (Invited)

Science.gov (United States)

Krumhansl, R.; Peach, C. L.; Busey, A.; Foster, J.; Baker, I.

To be climate literate, students must be data-literate. To connect with the evidence behind scientists' assertions about climate change, students (and other novices) must be able to distinguish long-term trends from short-term variability in graphs, recognize the distribution of sea surface temperature or precipitation changes on maps, and discern important patterns in animations that display changes in data over time. Although the development of cyberinfrastructure for accessing near digital, sharable, real-time and archived earth systems data has the potential to transform how climate science is taught by connecting students directly with evidence to support their understanding, online interfaces to scientific data are typically industrial-strength - built by scientists for scientists - and their design can significantly impede broad use by novices. To inform efforts at bridging scientific data portals to the classroom, Education Development Center, Inc. (EDC) and the Scripps Institution of Oceanography conducted an NSF-funded 2-year interdisciplinary review of literature and expert opinion pertinent to making interfaces to large scientific databases accessible to and usable by student learners and their instructors. The >70 cross-cutting and specific guidelines in our project report are grounded in the fundamentals of Cognitive Load Theory, Visual Perception, Schema theory and Universal Design for Learning. The components of the human visual system and associated cognitive processes are highly specialized and have evolved in response to survival demands of the three-dimensional world humans have lived in for thousands of years. Because the use of two-dimensional representations, such as maps and graphs, and the use and navigation of Web interfaces has developed quite recently in human history, our visual perception system is not specifically adapted to these tasks. Therefore, it's critical to understand how to design two-dimensional media to take advantage of

When large space settlements are finally built, inevitably the customers who pay for them will start the process by specifying requirements with a Request for Proposal (RFP). Although we are decades away from seeing the first of these documents, some of their contents can be anticipated now, and provide insight into the variety of elements that must be researched and developed before space settlements can happen. Space Settlement Design Competitions for High School students present design challenges in the form of RFPs, which predict basic requirements for space settlement attributes in the future, including structural features, infrastructure, living conveniences, computers, business areas, and safety. These requirements are generically summarized, and unique requirements are noted for specific space settlement locations and applications.

Inclusive design in architectural practice: Experiential learning of disability in architectural education.

Science.gov (United States)

Mulligan, Kerry; Calder, Allyson; Mulligan, Hilda

2018-04-01

The built environment can facilitate or impede an individual's ability to participate in society. This is particularly so for people with disability. Architects are well placed to be advocates for design that enhances societal equality. This qualitative study explored architectural design students' perceptions of inclusive design, their reflections resulting from an experiential learning module and the subsequent influence of these on their design practice. Twenty four architectural design students participated in focus groups or individual interviews. Data were analyzed thematically. Three themes were evident: 1) Inclusive design was perceived as challenging, 2) Appreciation for the opportunity to learn about the perspectives of people with disabilities, and 3) Change of attitude toward inclusive design. Experiential learning had fostered reflection, changes in attitude and the realization that inclusive design, should begin at the start of the design process. For equitable access for all people to become reality, experiential learning, coupled with positive examples of inclusive design should be embedded in architectural education.

Elementary Students' Learning of Materials Science Practices Through Instruction Based on Engineering Design Tasks

Science.gov (United States)

Wendell, Kristen Bethke; Lee, Hee-Sun

2010-12-01

Materials science, which entails the practices of selecting, testing, and characterizing materials, is an important discipline within the study of matter. This paper examines how third grade students' materials science performance changes over the course of instruction based on an engineering design challenge. We conducted a case study of nine students who participated in engineering design-based science instruction with the goal of constructing a stable, quiet, thermally comfortable model house. The learning outcome of materials science practices was assessed by clinical interviews conducted before and after the instruction, and the learning process was assessed by students' workbooks completed during the instruction. The interviews included two materials selection tasks for designing a sturdy stepstool and an insulated pet habitat. Results indicate that: (1) students significantly improved on both materials selection tasks, (2) their gains were significantly positively associated with the degree of completion of their workbooks, and (3) students who were highly engaged with the workbook's reflective record-keeping tasks showed the greatest improvement on the interviews. These findings suggest the important role workbooks can play in facilitating elementary students' learning of science through authentic activity such as engineering design.

2011-07-01

Background and purpose: The aim of this study was to explore the effect of investigative activities with manipulations in a virtual laboratory on students' ability to design experiments. Sample Fourteen students in a lower secondary school in Greece attended a teaching sequence on thermal phenomena based on the use of information and communication technology, and specifically of the simulated virtual laboratory 'ThermoLab'. Design and methods A pre-post comparison was applied. Students' design of experiments was rated in eight dimensions; namely, hypothesis forming and verification, selection of variables, initial conditions, device settings, materials and devices used, process and phenomena description. A three-level ranking scheme was employed for the evaluation of students' answers in each dimension. Results A Wilcoxon signed-rank test revealed a statistically significant difference between the students' pre- and post-test scores. Additional analysis by comparing the pre- and post-test scores using the Hake gain showed high gains in all but one dimension, which suggests that this improvement was almost inclusive. Conclusions We consider that our findings support the statement that there was an improvement in students' ability to design experiments.

Jamie Costley

2017-05-01

Full Text Available Aim/Purpose: The number of students enrolled in online courses that use video lectures is on the rise. However, research shows that the number of students watching video lectures is low, and the number watching videos to completion is even lower. Background: This paper seeks to understand this problem by looking for correlations between instructional design and student engagement with video lectures. Methodology: Students at a cyber-university in South Korea (n=1801 were surveyed on their perception of the instructional design used in the courses they took and their engagement with online video lectures. Contribution: This paper contributes to the body of knowledge by demonstrating positive correlations between instructional design, watching, and finishing video lectures. Findings: While most other research has found low levels of online lecture viewership, this paper found significantly higher numbers watching and finishing videos. Other major findings of the paper are that five key elements of instructional design for online learning environments (designing methods, setting the curriculum, establishing time parameters, establishing netiquette, and utilizing the medium effectively all correlated positively with students watching and finishing video lectures. Recommendations for Practitioners\t: Based on findings in this paper, it is recommended that practitioners consider taking actions when designing their instruction for online courses. These include batching their video lectures together by topic, devoting greater resources to helping students utilize the medium, and communicate time parameters in a way that encourages students to view video lectures in a timely manner. Recommendation for Researchers: As the watching of video lectures in this study was mandatory for learners, an interesting area of further research would be to examine whether that decision led to higher numbers of students watching them. Future Research: It is important for

The Advanced Envelope Research effort will provide factory homebuilders with high performance, cost-effective envelope designs that can be effectively integrated into the plant production process while meeting the thermal requirements of the 2012 IECC standards. This work is part of a multiphase effort. Phase 1 identified seven envelope technologies and provided a preliminary assessment of three methods for building high performance walls. Phase 2 focused on developing viable product designs, manufacturing strategies, addressing code and structural issues, and cost analysis of the three selected options. An industry advisory committee helped narrow the research focus to perfecting a stud wall design with exterior continuous insulation (CI). This report describes Phase 3, which was completed in two stages and continued the design development effort, exploring and evaluating a range or methods for applying CI to factory built homes. The scope also included material selection, manufacturing and cost analysis, and prototyping and testing. During this phase, a home was built with CI, evaluated, and placed in service. The experience of building a mock up wall section with CI and then constructing on line a prototype home resolved important concerns about how to integrate the material into the production process. First steps were taken toward finding least expensive approaches for incorporating CI in standard factory building practices and a preliminary assessment suggested that even at this early stage the technology is attractive when viewed from a life cycle cost perspective.

Linda Corkery

2004-06-01

Full Text Available This paper describes an action-research project undertaken to explore teaching and learning in the design studio in the Faculty of the Built Environment (FBE, University of New South Wales, Sydney. The research project involved three undergraduate design programmes (architecture, interior architecture and landscape architecture within the FBE, however this paper will focus only on the findings related to the Bachelor of Landscape Architecture (BLArch programme. The studio is at the core of the design-based curriculum for the landscape architecture degree. This setting nurtures and encourages students to demonstrate a range of capabilities and attributes expected in professional practice. Design projects are complex, integrated assessment tasks. While design teachers use criteria to assess knowledge and skills, students often feel the judgement of overall design project excellence is based on subjective interpretation. There is also concern about the effectiveness of design teaching across the studios. Specifically, the study identified students' perceptions of what constitutes the mark of High Distinction (HD and characteristics of the ideal design teacher. This paper does not present a discourse analysis of the theoretical framework and concepts of the research project. That material is presented in previous and subsequent publications (Corkery et al, 2003.

Design of Soil Salinity Policies with Tinamit, a Flexible and Rapid Tool to Couple Stakeholder-Built System Dynamics Models with Physically-Based Models

Model coupling is a crucial step to constructing many environmental models, as it allows for the integration of independently-built models representing different system sub-components to simulate the entire system. Model coupling has been of particular interest in combining socioeconomic System Dynamics (SD) models, whose visual interface facilitates their direct use by stakeholders, with more complex physically-based models of the environmental system. However, model coupling processes are often cumbersome and inflexible and require extensive programming knowledge, limiting their potential for continued use by stakeholders in policy design and analysis after the end of the project. Here, we present Tinamit, a flexible Python-based model-coupling software tool whose easy-to-use API and graphical user interface make the coupling of stakeholder-built SD models with physically-based models rapid, flexible and simple for users with limited to no coding knowledge. The flexibility of the system allows end users to modify the SD model as well as the linking variables between the two models themselves with no need for recoding. We use Tinamit to couple a stakeholder-built socioeconomic model of soil salinization in Pakistan with the physically-based soil salinity model SAHYSMOD. As climate extremes increase in the region, policies to slow or reverse soil salinity buildup are increasing in urgency and must take both socioeconomic and biophysical spheres into account. We use the Tinamit-coupled model to test the impact of integrated policy options (economic and regulatory incentives to farmers) on soil salinity in the region in the face of future climate change scenarios. Use of the Tinamit model allowed for rapid and flexible coupling of the two models, allowing the end user to continue making model structure and policy changes. In addition, the clear interface (in contrast to most model coupling code) makes the final coupled model easily accessible to stakeholders with

DESIGN WITH THE SENSES AND FOR THE SENSES: AN ALTERNATIVE TEACHING MODEL FOR DESIGN STUDIO

Directory of Open Access Journals (Sweden)

May al-Ibrashy

2010-07-01

Full Text Available In the 1990s, Juhani Pallasmaa wrote a compact, yet, eye-opening book expressing his growing concern about the architectural profession’s waning ability to reference all the senses of the body in the design process. Bit by bit, the perceptive chasm between the architect and architecture was widening both in the design process and in the cognitive experience of existing architecture. More than a decade later, these concerns have heightened as the ramifications of this design divide appear in the form of architecture whose divorced virtual quality has spilled over from the design process into built reality. The illusion of virtual reality – as achieved by 3D simulation in all its glories – has pulled the architect into a zone of false confidence where he/she feels that the design has come to life before it is built and that every corner and detail can be simulated and therefore understood. But can it be touched, smelt, tasted or heard? In fact, is even what we see on the screen anywhere close to what we see as we move bodily through its spaces? This phenomenon is addressed in a design studio run by the two authors of this paper. The purpose of the design studio, which is held in the Department of Architectural Engineering, of the Faculty of Engineering of the British University in Egypt, is to design a community centre linked to a place of worship within a residential compound currently under construction on the outskirts of Cairo. The graduating class of ten students is in the final and fourth year of a program that emphasized the engineering and project management aspects of architecture at the expense of theory and history of art and architecture. The university has no humanities or liberal arts program as yet, and students have minimal contact to arts within the university system. Contact hours in design studios are limited and design is mostly computer-aided. The need to re-emphasize the physical, tactile, polemic and holistic aspects

Examining Vegetation of Built Landscapes and Their Relationship to Existing Ecosystems

Directory of Open Access Journals (Sweden)

Margaret Livingston

2004-06-01

Full Text Available An understanding of the various influences of urbanisation on plant communities is critical for planning a sustainable future for the planet. For example, landscape practices and sense of place driven by aesthetic influences often dominate in the design of built landscapes, resulting in strikingly different vegetation communities from that of the surrounding communities. Furthermore, these built landscapes in metropolitan areas often markedly influence an inhabitant's impressions of a region's biotic foundation and sense of place. Inhabitants may not consider or understand the ecological impacts of practices that are typically dominated by contemporary cultural aesthetics. Do these cultural aesthetic drivers result in relatively similar landscapes in terms of appearance, regardless of region? The purpose of this study was to document general trends in landscape structure and composition from two distinct, different regions. Specifically, we addressed the questions: how do these built landscapes deviate from their surrounding natural communities and are these built landscapes from the two regions similar in structure and composition? This paper characterised landscape vegetation patterns of typical residential areas in two cities with relatively diverse climatic regions, Tucson, Arizona and Atlanta, Georgia. Comparisons were done on data for plant diversity, density, life form (tree, shrub, groundcover, and vines and species origin (native versus non-native from sites within typical residential subdivisions throughout the two cities. Results were compared with the composition of local typology in order to determine what differences and similarities existed in relation to native biotic communities. In both cities, residential landscapes converged on savannah-type landscapes, emphasising scattered overstory and minimal understory that were more compositionally diverse than the native biotic communities because of the introduction of non

The child active transportation literature has focused on walking, with little attention to risk associated with increased traffic exposure. This paper reviews the literature related to built environment correlates of walking and pedestrian injury in children together, to broaden the current conceptualization of walkability to include injury prevention. Two independent searches were conducted focused on walking in children and child pedestrian injury within nine electronic databases until March, 2012. Studies were included which: 1) were quantitative 2) set in motorized countries 3) were either urban or suburban 4) investigated specific built environment risk factors 5) had outcomes of either walking in children and/or child pedestrian roadway collisions (ages 0-12). Built environment features were categorized according to those related to density, land use diversity or roadway design. Results were cross-tabulated to identify how built environment features associate with walking and injury. Fifty walking and 35 child pedestrian injury studies were identified. Only traffic calming and presence of playgrounds/recreation areas were consistently associated with more walking and less pedestrian injury. Several built environment features were associated with more walking, but with increased injury. Many features had inconsistent results or had not been investigated for either outcome. The findings emphasise the importance of incorporating safety into the conversation about creating more walkable cities.

Integrated Design for Geoscience Education with Upward Bound Students

2009-05-01

Capturing the interest of our students is imperative to expand the conduit of future Earth scientists in the United States. According to the Rising Above the Gathering Storm report (2005), we must increase America's talent pool by improving K-12 mathematics and science education. Geoscience education is uniquely suited to accomplish this goal, as we have become acutely aware of our sensitivity to the destructive forces of nature. The educational community must take advantage of this heightened awareness to educate our students and ensure the next generation rebuilds the scientific and technological base on which our society rests. In response to these concerns, the National Science Foundation advocates initiatives in Geoscience Education such as IDGE (Integrated Design for Geoscience Education), which is an inquiry-based geoscience program for Upward Bound (UB) students at Marshall University in Huntington, West Virginia. The UB program targets low-income under-represented students for a summer academic-enrichment program. IDGE builds on the mission of UB by encouraging underprivileged students to investigate science and scientific careers. During the two year project, high school students participated in an Environmental Inquiry course utilizing GLOBE program materials and on-line learning modules developed by geoscience specialists in land cover, soils, hydrology, phenology, and meteorology. Students continued to an advanced course which required IDGE students to collaborate with GLOBE students from Costa Rica. The culmination of this project was an educational expedition in Costa Rica to complete ecological field studies, providing first-hand knowledge of the international responsibility we have as scientists and citizens of our planet. IDGE was designed to continuously serve educators and students. By coordinating initiatives with GLOBE headquarters and the GLOBE country community, IDGE's efforts have yielded multiple ways in which to optimize positive

Zwolski, K

2000-01-01

The website described was not designed to replace classroom teaching, but to serve as an additional tool for students attending a traditional course. Based on my experience and the data obtained from the evaluation questionnaire, the following points can be made: students are enthusiastic about the Internet and will access a web page that accompanies a particular course or courses a website can allow for objectives, not normally engendered by traditional methods, to be achieved. These may include, for instance, fostering a sense of community, providing new means of communication between professor and student and serving as a portal to the vast resources of the Internet. A single-theme website can effectively address the learning needs of students at different levels, in this case both undergraduate and graduate students A well-designed website can increase the visibility of the educational institution that sponsors it It is not easy to measure a website's effectiveness in helping students achieve traditional course objectives or its impact on student learning. The questionnaire results confirm students' satisfaction with the website and their belief that it was an important and useful learning tool. This is significant and positive. Future research is needed to measure the degree to which a website can increase learning in a particular area. The site required about 150 hours to construct and about 6-8 hours per week to maintain. This is a considerable amount of faculty time. Although I cannot speak for others, I firmly believe that this is a worthwhile investment. The website is clearly appreciated by students, and it seems logical to conclude that it is fulfilling some learning needs that may not be met by other methods. In addition, it provides the educator with a new vehicle for communication. It is exhilarating to create with new formats and to use expertise in a given area to reach students, foster community, and establish a presence beyond the classroom

A state-of-the-art review of built environment information modelling (BeIM

Directory of Open Access Journals (Sweden)

Tah J.H.M.

2017-12-01

Full Text Available Elements that constitute the built environment are vast and so are the independent systems developed to model its various aspects. Many of these systems have been developed under various assumptions and approaches to execute functions that are distinct, complementary or sometimes similar. Furthermore, these systems are ever increasing in number and often assume similar nomenclatures and acronyms, thereby exacerbating the challenges of understanding their peculiar functions, definitions and differences. The current societal demand to improve sustainability per­formance through collaboration as well as whole-system and through-life thinking is driving the need to integrate independent systems associated with different aspects and scales of the built environment to deliver smart solutions and services that improve the well-being of citizens. The contemporary object-oriented digitization of real-world elements appears to provide a leeway for amalgamating the modelling systems of various domains in the built environment which we termed as built environment information modelling (BeIM. These domains include architecture, engineering, construction as well as urban planning and design. Applications such as building information modelling, geographic information systems and 3D city modelling systems are now being integrated for city modelling purposes. The various works directed at integrating these systems are examined, revealing that current research efforts on integration fall into three categories: (1 data/file conversion systems, (2 semantic mapping systems and (3 the hybrid of both. The review outcome suggests that good knowledge of these domains and how their respective systems operate is vital to pursuing holistic systems integration in the built environment.

Enhanced teaching and student learning through a simulator-based course in chemical unit operations design

Ghasem, Nayef

2016-07-01

This paper illustrates a teaching technique used in computer applications in chemical engineering employed for designing various unit operation processes, where the students learn about unit operations by designing them. The aim of the course is not to teach design, but rather to teach the fundamentals and the function of unit operation processes through simulators. A case study presenting the teaching method was evaluated using student surveys and faculty assessments, which were designed to measure the quality and effectiveness of the teaching method. The results of the questionnaire conclusively demonstrate that this method is an extremely efficient way of teaching a simulator-based course. In addition to that, this teaching method can easily be generalised and used in other courses. A student's final mark is determined by a combination of in-class assessments conducted based on cooperative and peer learning, progress tests and a final exam. Results revealed that peer learning can improve the overall quality of student learning and enhance student understanding.

2004-01-01

This paper is a culmination of a 2-year project involving students, faculty, staff member, and private industry. Solar Technology Education Project (STEP) became the first student-led group to successfully install a 36-panel photovoltaic (PV) array on a Canadian University campus. The fundraising, design, and assembly of the PV array was entirely student driven. The project was completed in January 2004 with the installation of a 2 kW photovoltaic grid-tied array mounted to the roof of the University of Waterloo's Federation Hall, the largest student-run pub in North America. The photovoltaic array was a demonstration project to raise awareness about solar technology and the need for energy efficiency in buildings. It took two years to complete the project, which was implemented in three phases. The first phase was aimed at raising the required capital. The second phase included design and fabrication of the array. The third phase, still ongoing today, is the community outreach phase, which involves educating the surrounding communities about the project, solar technology, and the role of individuals in combating global warming. This paper examines the steps required for the implementation of a successful educational photovoltaic project, using the students' experience as a roadmap. A section highlighting what's next for STEP is also presented as the students attempt to build on the momentum from the project. The aim is to launch a solar thermal project on another University of Waterloo building to move one step closer to the ultimate goal of a sustainable campus

2017-06-01

The learning requirements of diverse groups of students in higher education challenge educators to design learning interventions that meet the need of 21st century students. A model was developed to assist lecturers, especially those that are new to the profession, to use a blended approach to design meaningful learning interventions for physiology. The aim of the model is to encourage methodical development of learning interventions, while the purpose is to provide conceptual and communication tools that can be used to develop appropriate operational learning interventions. A whole brain approach that encourages challenging the four quadrants is encouraged. The main arguments of the model are to first determine the learning task requirements, as these will inform the design and development of learning interventions to facilitate learning and the assessment thereof. Delivery of the content is based on a blended approach. Copyright © 2017 the American Physiological Society.

Evaluation of the safety of the operating nuclear power plants built to earlier standards

International Nuclear Information System (INIS)

Menteseoglu, S.

2001-01-01

The objective of this paper is to provide practical assistance on judging the safety of a nuclear power plant, on the basis of a comparison with current safety standards and operational practices. For nuclear power plants built to earlier standards for which there are questions about the adequacy of the maintenance of the plant design and operational practices, a safety review against current standards and practices can be considered a high priority. The objective of reviewing nuclear power plants built to earlier standards against current standards and practices is to determine whether there are any deviations which would have an impact on plant safety. The safety significance of the issues identified should be judged according to their implications for plant design and operation in terms of basic safety concepts such as defence in depth and safety culture. In addition, this paper provides assistance on the prioritization of corrective measures and their implementation so as to approach an acceptable level of safety

Professionals such as gerontologists play an important role in the design, development and implementation of age-friendly services. and products, by using working methods and principles of co-creation. A Dutch undergraduate applied gerontology programme aims to train students in the why, how and what of co-creation. The degree to which students are intrinsically motivated to develop competencies depends on how their psychological needs are met. These needs are autonomy, an awareness of competence and a sense of relatedness, as described in the self-determination theory. To nurture the intrinsic motivation of the applied gerontology students, a realistic, powerful learning environment called the Living Lab Applied Gerontology was designed and implemented. The aim of this paper is to present the design of this powerful learning environment and to discuss its value for nurturing the students' intrinsic motivation for co-creation. Based on a focus group with eight students, we identify directions for further research and development of living labs.

2005-01-01

A simple current mirror using TFTs with input terminals which are capacitively coupled to the TFT gate, is used in this work, to design a built-in current sensor (BICS). The important feature in this application is that the voltage drop across the sensing TFT device can be reduced to almost zero value, while preserving transistor operation in the saturation region. This makes the proposed BICS appropriate for TFT applications without affecting the circuit operation. It also results in adequate linearity for the current monitoring, making the structure applicable to digital as well as to analog and mixed-signal circuit testing.

Development and Validation of a Rubric for Diagnosing Students' Experimental Design Knowledge and Difficulties.

Dasgupta, Annwesa P; Anderson, Trevor R; Pelaez, Nancy

2014-01-01

It is essential to teach students about experimental design, as this facilitates their deeper understanding of how most biological knowledge was generated and gives them tools to perform their own investigations. Despite the importance of this area, surprisingly little is known about what students actually learn from designing biological experiments. In this paper, we describe a rubric for experimental design (RED) that can be used to measure knowledge of and diagnose difficulties with experimental design. The development and validation of the RED was informed by a literature review and empirical analysis of undergraduate biology students' responses to three published assessments. Five areas of difficulty with experimental design were identified: the variable properties of an experimental subject; the manipulated variables; measurement of outcomes; accounting for variability; and the scope of inference appropriate for experimental findings. Our findings revealed that some difficulties, documented some 50 yr ago, still exist among our undergraduate students, while others remain poorly investigated. The RED shows great promise for diagnosing students' experimental design knowledge in lecture settings, laboratory courses, research internships, and course-based undergraduate research experiences. It also shows potential for guiding the development and selection of assessment and instructional activities that foster experimental design. © 2014 A. P. Dasgupta et al.

Narayanan, M.

2017-12-01

Encouraging student participation while designing writing exercises requires a certain pragmatic approach. Wilbert James McKeachie is the author of a widely read textbook on college teaching. McKeachie was a longtime faculty member at the University of Michigan. He served as president of the American Psychological Association, the American Psychological Foundation and the American Association of Higher Education. In his famous book Teaching and Learning in the College Classroom, McKeachie provides an introduction and notes the role of research in identifying new goals for higher education. He also offers a conceptual framework based on a student mediation model and a focuses on the processs-product relationships between faculty teacher behavior and student learning outcomes. McKeachie' s Teaching Tips provides helpful strategies for dealing with both the everyday problems of university teaching and those that arise in trying to maximize learning for every student. The book does not suggest a set of recipes to be followed mechanically; it gives instructors the tools they need to deal with the ever-changing dynamics of teaching and learning. First, it is extremely important to define the target skill areas and means of implementation. Next, the professor can then proceed to focus on the techniques that could be employed to ensure student participation. This includes selection of an appropriate topic that is relevant to the field of study as well as classroom learning experiences. By pragmatically combining these objectives, the teacher can expect both enthusiasm and effective learning among the student population. McKeachie, Wilbert James.

This project-based learning combined the chemistry of separation process using steam distillation with engineering design process in an undergraduate chemistry course. Students built upon their knowledge of phase changes, immiscible mixture, and the relationship between vapor pressure and boiling point to complete a project of modifications steam distillation apparatus. The research method is a qualitative case study, which aims to describe how (1) the creative thinking skills of students emerged during six weeks of theproject, (2) students built steam distillation apparatus characteristics as the project product and (3) students response to the project-based learning model. The results showed that the students had successfully constructed a steam distillation apparatus using plastic kettle as steam generator and distillation flask. A Plastic tubewas used to drain water vapor from steam generator to distillation flask and to drain steam containing essential oil to the condenser. A biscuit tin filled with ice was used as a condenser. The time required until resulting distillate was fifteen minutes. The production of essential was conductive qualitatively by a very strong smell typical of essential oil and two phases of distillate. Throughout the project, students formulated the relevant and varied problem, formulated the goals, proposed the ideas of the apparatus and materials, draw apparatus design, constructed apparatus, tested apparatus, evaluated, and reported the project. Student response was generally positive. They were pleased, interested, more understanding the concepts and work apparatus principles, also implemented new ideas. These results indicate that project-based learning can develop students' creative thinking skills. Based on these results, it is necessary to conduct research and implemented project-based learning to other concepts.

The Advanced Envelope Research effort will provide factory homebuilders with high performance, cost-effective envelope designs that can be effectively integrated into the plant production process while meeting the thermal requirements of the 2012 IECC standards. Given the affordable nature of manufactured homes, impact on first cost is a major consideration in developing new envelope technologies. This work is part of a multi-phase effort. Phase 1 identified seven envelope technologies and provided a preliminary assessment of three methods for building high performance walls. Phase 2 focused on developing viable product designs, manufacturing strategies, addressing code and structural issues, and cost analysis of the three selected options. An industry advisory committee helped narrow the research focus to perfecting a stud wall design with exterior continuous insulation (CI). Phase 3, completed in two stages, continued the design development effort, exploring and evaluating a range or methods for applying CI to factory built homes. The scope also included material selection, manufacturing and cost analysis, and prototyping and testing. During this phase, a home was built with CI, evaluated, and placed in service. The experience of building a mock up wall section with CI and then constructing on line a prototype home resolved important concerns about how to integrate the material into the production process. First steps were taken toward finding least expensive approaches for incorporating CI in standard factory building practices and a preliminary assessment suggested that even at this early stage the technology is attractive when viewed from a life cycle cost perspective.

The increasing complexity of medical curricula would benefit from adaptive computer supported collaborative learning systems that support study management using instructional design and learning object principles. However, to our knowledge, there are scarce reports regarding applications developed to meet this goal and encompass the complete medical curriculum. The aim of ths study was to develop and assess the usability of an adaptive computer supported collaborative learning system for medical students to manage study sessions. A study platform named ALERT STUDENT was built as a free web application. Content chunks are represented as Flashcards that hold knowledge and open ended questions. These can be created in a collaborative fashion. Multiple Flashcards can be combined into custom stacks called Notebooks that can be accessed in study Groups that belong to the user institution. The system provides a Study Mode that features text markers, text notes, timers and color-coded content prioritization based on self-assessment of open ended questions presented in a Quiz Mode. Time spent studying and Perception of knowledge are displayed for each student and peers using charts. Computer supported collaborative learning is achieved by allowing for simultaneous creation of Notebooks and self-assessment questions by many users in a pre-defined Group. Past personal performance data is retrieved when studying new Notebooks containing previously studied Flashcards. Self-report surveys showed that students highly agreed that the system was useful and were willing to use it as a reference tool. The platform employs various instructional design and learning object principles in a computer supported collaborative learning platform for medical students that allows for study management. The application broadens student insight over learning results and supports informed decisions based on past learning performance. It serves as a potential educational model for the medical

The Gem Infrasound Logger and Custom-Built Instrumentation

International Nuclear Information System (INIS)

Anderson, Jacob F.; Ronan, Timothy J.

2017-01-01

Here, we designed, built, and recorded data with a custom infrasound logger (referred to as the Gem) that is inexpensive, portable, and easy to use. We also describe its design process, qualities, and applications in this article. Field instrumentation is a key element of geophysical data collection, and the quantity and quality of data that can be recorded is determined largely by the characteristics of the instruments used. Geophysicists tend to rely on commercially available instruments, which suffice for many important types of fieldwork. However, commercial instrumentation can fall short in certain roles, which motivates the development of custom sensors and data loggers. Particularly, we found existing data loggers to be expensive and inconvenient for infrasound campaigns, and developed the Gem infrasound logger in response. In this article, we discuss development of this infrasound logger and the various uses found for it, including projects on volcanoes, high-altitude balloons, and rivers. Further, we demonstrate that when needed, scientists can feasibly design and build their own specialized instruments, and that doing so can enable them to record more and better data at a lower cost.

Comparing problem-based learning and lecture as methods to teach whole-systems design to engineering students

Science.gov (United States)

Dukes, Michael Dickey

The objective of this research is to compare problem-based learning and lecture as methods to teach whole-systems design to engineering students. A case study, Appendix A, exemplifying successful whole-systems design was developed and written by the author in partnership with the Rocky Mountain Institute. Concepts to be tested were then determined, and a questionnaire was developed to test students' preconceptions. A control group of students was taught using traditional lecture methods, and a sample group of students was taught using problem-based learning methods. After several weeks, the students were given the same questionnaire as prior to the instruction, and the data was analyzed to determine if the teaching methods were effective in correcting misconceptions. A statistically significant change in the students' preconceptions was observed in both groups on the topic of cost related to the design process. There was no statistically significant change in the students' preconceptions concerning the design process, technical ability within five years, and the possibility of drastic efficiency gains with current technologies. However, the results were inconclusive in determining that problem-based learning is more effective than lecture as a method for teaching the concept of whole-systems design, or vice versa.

Student Responses to a Flipped Introductory Physics Class with built-in Post-Video Feedback Quizzes

Science.gov (United States)

Ramos, Roberto

We present and analyze student responses to multiple Introductory physics classes in a university setting, taught in a ''flipped'' class format. The classes included algebra- and calculus-based introductory physics. Outside class, students viewed over 100 online video lectures on Classical Mechanics, Electricity and Magnetism, and Modern Physics prepared by this author and in some cases, by a third-party lecture package available over YouTube. Inside the class, students solved and discussed problems and conceptual issues in greater detail. A pre-class online quiz was deployed as an important source of feedback. I will report on the student reactions to the feedback mechanism, student responses using data based on anonymous surveys, as well as on learning gains from pre-/post- physics diagnostic tests. The results indicate a broad mixture of responses to different lecture video packages that depend on learning styles and perceptions. Students preferred the online quizzes as a mechanism to validate their understanding. The learning gains based on FCI and CSEM surveys were significant.

Scaffolding and interventions between students and teachers in a Learning Design Sequence

Directory of Open Access Journals (Sweden)

Eva Edman Stålbrandt

Full Text Available The aims of this paper are to develop knowledge about scaffolding when students in Swedish schools use digital educational material and to investigate what the main focus is in teachers' interventions during a Learning Design Sequence (LDS, based on a socio-cultural perspective. The results indicate that scaffolding were most common in the primary transformation unit and the most frequent type was procedural scaffolding, although all types of scaffolds; conceptual, metacognitive, procedural, strategic, affective and technical scaffolding occurred in all parts of a learning design sequence. In this study most of the teachers and students, think that using digital educational material requires more and other forms of scaffolding and concerning teacher interventions teachers interact both supportively and restrictively according to students' learning process. Reasons for that are connected to the content of the intervention and whether teachers intervene together with the students or not.

Zhou, Ao; Wong, Kwun-Wah

2014-01-01

Air-conditioning system plays a significant role in providing users a thermally comfortable indoor environment, which is a necessity in modern buildings. In order to save the vast energy consumed by air-conditioning system, the building envelopes in envelope-load dominated buildings should be well designed such that the unwanted heat gain and loss with environment can be minimized. In this paper, a new design of concrete wall panel that enhances thermal insulation of buildings by adding a gypsum layer inside concrete is presented. Experiments have been conducted for monitoring the temperature variation in both proposed sandwich wall panel and conventional concrete wall panel under a heat radiation source. For further understanding the thermal effect of such sandwich wall panel design from building scale, two three-story building models adopting different wall panel designs are constructed for evaluating the temperature distribution of entire buildings using finite element method. Both the experimental and simulation results have shown that the gypsum layer improves the thermal insulation performance by retarding the heat transfer across the building envelopes. PMID:25177718

Designing Science Learning Environments That Support Emerging Bilingual Students to Problematize Electrical Phenomena

Science.gov (United States)

Suarez, Enrique A.

This dissertation investigates how emerging bilingual students make sense of natural phenomena through engaging in certain epistemic practices of science, and the elements of the learning environment that created those opportunities. Specifically, the dissertation focuses on how emerging bilingual students problematized electrical phenomena, like electric flow and electrical resistance, and how the design features of the environment (e.g., sequencing of activities, linguistic practices) may have supported students as they made sense of phenomena. The first study describes how for students presented and evaluated mechanistic models of electric flow, focusing specifically on how students identified and negotiated a disagreement between their explanatory models. The results from this study highlight the complexity of students' disagreements, not only because of the epistemological aspects related to presenting and evaluating knowledge, but also due to interpersonal dynamics and the discomfort associated with disagreeing with another person. The second study focuses on the design features of the learning environment that supported emerging bilingual students' investigations of electrical phenomena. The findings from this study highlight how a carefully designed set of activities, with the appropriate material resources (e.g., experimental tools), could support students to problematize electrical resistance. The third study describes how emerging bilingual students engaged in translanguaging practices and the contextual features of the learning environment that created and hindered opportunities for translanguaging. The findings from this study identify and articulate how emerging bilingual students engaged in translanguaging practices when problematizing electrical resistance, and strengthen the perspective that, in order to be equitable for emerging bilingual students, science learning environments need to act as translanguaging spaces.

Keating, Elizabeth M; O'Donnell, Erin P; Starr, Stephanie R

2013-01-01

In recent years, medical students have recognized and advocated for opportunities to explore various specialties earlier in their medical education. A brief literature review, however, reveals little consensus on the best approach to introduce students to different fields during their preclinical years. We present one of the first reports of a student-led effort to design and implement a preclinical specialty-specific elective. At Mayo Medical School, for two consecutive years the student president of the Pediatric Interest Group has created a peer-designed weeklong group elective ("selective") experience consisting of workshops, faculty and resident panel discussions, and clinical shadowing experiences based on a student needs assessment. Each year, more than 25% of the first- and second-year medical student body participated. The majority of students who completed the selective agreed that this experience heightened their interests and expanded their knowledge about pediatrics. The pediatric group selective has provided students with important resources for their medical education and future careers. Students found the group selective beneficial to their learning experience and recommend continuing to offer it in the future.

A BIO-EXPERIENTIAL MODEL FOR LEARNING CREATIVE DESIGN PRACTICES THAT SUPPORTS TRANSFORMATIVE DEVELOPMENT IN BEGINNING DESIGN STUDENTS

Directory of Open Access Journals (Sweden)

Stephen Temple

2010-07-01

Full Text Available This paper asks what beginning design learning experiences best support the remainder of design education. It is a conjecture of brain-based learning theory that a student’s direct, concrete primary experiences are responsible for the construction of fundamental structures of neural processing as “hard wired” pathways. These structures then form the ground of and set into play patterns of later more abstracted learning experiences. Pedagogy of basic design courses that seeks introduction of creative processes as a foundation for design education must recognize these experiential, biologically developmental relationships as basic to developmentally appropriate beginning design curriculum. This paper models a beginning design pedagogy on developmental relationships between concrete and abstract processes of learning as a basis for transformative creative thinking that enables student self-development that progresses up the curriculum. Aligning with developmental learning theories (Piaget and others, a basic tenant of this approach is that learning at the primary level of direct experience self initiates brain changes where students form their own structure of learning. Thus, initial learning experiences will be those that best enable decision-making consistent with the biological interactivity between body and mind, between, respectively, the concrete and the abstract. This is important because the designed environment in which we all live is grounded in the development of abstract content experientially based in concrete material physicality. Experiential learning theories (Kolb and others, following Piaget identify concrete and abstract learning as fundamental poles for acquiring and acting on knowledge: Concrete learning involves direct experiential engagement through heuristic discovery and reflection and abstract learning involves indirect representational cues in acts of conceptualization, synthesis, and experimentation.

Full Text Available Courses on Human Computer Interaction (HCI largely differ in the conception of the role of the course in the program, in the topics to be included, in emphases, in the instructional strategies that are employed, and more. This paper describes the design and implementation of a HCI course for students of the Management Information Systems department in our college. Students’ intermediate and final homework assignments were analyzed to provide feedback for the course design. Quantitative analysis showed high correlation between the quality of the requirement analysis performed by the students and the quality of the final interface prototype, and also that the quality of design alternatives that were considered by the students can be a good predictor for the quality of the overall interface design. Qualitative analysis of students’ submissions showed the need for practicing skills required in users’ studies, especially conducting interviews and observations. Implications from these and other findings are discussed.

The Collisional Accretion Experiment (CATE) was designed, built, and flown on NASA's C-9 parabolic flight airplane in less than a year by an interdisciplinary team of 6 undergraduate students under the supervision of two faculty. CATE was selected in the initial NASA Undergraduate Student Instrument Project (USIP) solicitation in the Fall of 2013, and the experiment flight campaign was in July 2014. The experiment studied collisions between different particle populations at low velocities (sub-m/s) in a vacuum and microgravity to gain insight into processes in the protoplanetary disk and planetary ring systems. Faculty provided the experiment concept and key experiment design parameters, and the student team developed the detailed hardware design for all components, manufactured and tested hardware, operated the experiment in flight, and analyzed data post-flight. Students also developed and led an active social media campaign and education and public outreach campaign to engage local high school students in the project. The ability to follow an experiment through from conception to flight was a key benefit for undergraduate students whose available time for projects such as this is frequently limited to their junior and senior years. Key factors for success of the program included having an existing laboratory infrastructure and experience in developing flight payloads and an intrinsically simple experiment concept. Students were highly motivated, in part, by their sense of technical and scientific ownership of the project, and this engagement was key to the project's success.

Visually impaired students (VIS) are unable to get visual information, which has made their learning process complicated. This paper discusses the overall situation of VIS in Bangladesh and identifies major challenges that they are facing in getting education. The Braille system is followed to educate blind students in Bangladesh. However, lack of Braille based educational resources and technological solutions have made the learning process lengthy and complicated for VIS. As a developing country, Bangladesh cannot afford for the costly Braille related technological tools for VIS. Therefore, a mobile phone based Braille application, "mBRAILLE", for Android platform is designed to provide an easy Braille learning technology for VIS in Bangladesh. The proposed design is evaluated by experts in assistive technology for students with disabilities, and advanced learners of Braille. The application aims to provide a Bangla and English Braille learning platform for VIS. In this paper, we depict iterative (participatory) design of the application along with a preliminary evaluation with 5 blind subjects, and 1 sighted and 2 blind experts. The results show that the design scored an overall satisfaction level of 4.53 out of 5 by all respondents, indicating that our design is ready for the next step of development.

To identify factors which limit the ability of local governments to make appropriate investments in the built environment to promote youth health and reduce obesity outcomes in Atlantic Canada. Policy-makers and professionals participated in focus groups to discuss the receptiveness of local governments to introducing health considerations into decision-making. Seven facilitated focus groups involved 44 participants from Atlantic Canada. Thematic discourse analysis of the meeting transcripts identified systemic barriers to creating a built environment that fosters health for youth aged 12-15 years. Participants consistently identified four categories of barriers. Financial barriers limit the capacities of local government to build, maintain and operate appropriate facilities. Legacy issues mean that communities inherit a built environment designed to facilitate car use, with inadequate zoning authority to control fast food outlets, and without the means to determine where schools are built or how they are used. Governance barriers derive from government departments with distinct and competing mandates, with a professional structure that privileges engineering, and with funding programs that encourage competition between municipalities. Cultural factors and values affect outcomes: people have adapted to car-oriented living; poverty reduces options for many families; parental fears limit children's mobility; youth receive limited priority in built environment investments. Participants indicated that health issues have increasing profile within local government, making this an opportune time to discuss strategies for optimizing investments in the built environment. The focus group method can foster mutual learning among professionals within government in ways that could advance health promotion.

Full Text Available Built environment attributes have been linked to cardiovascular disease (CVD risk. Therefore, identifying built environment attributes that are associated with CVD risk is relevant for facilitating effective public health interventions.To conduct a systematic review of literature to examine the influence of built environmental attributes on CVD risks.Multiple database searches including Science direct, CINAHL, Masterfile Premier, EBSCO and manual scan of reference lists were conducted.Studies published in English between 2005 and April 2015 were included if they assessed one or more of the neighborhood environmental attributes in relation with any major CVD outcomes and selected risk factors among adults.Author(s, country/city, sex, age, sample size, study design, tool used to measure neighborhood environment, exposure and outcome assessments and associations were extracted from eligible studies.Eighteen studies met the inclusion criteria. Most studies used both cross-sectional design and Geographic Information System (GIS to assess the neighborhood environmental attributes. Neighborhood environmental attributes were significantly associated with CVD risk and CVD outcomes in the expected direction. Residential density, safety from traffic, recreation facilities, street connectivity and high walkable environment were associated with physical activity. High walkable environment, fast food restaurants, supermarket/grocery stores were associated with blood pressure, body mass index, diabetes mellitus and metabolic syndrome. High density traffic, road proximity and fast food restaurants were associated with CVDs outcomes.This study confirms the relationship between neighborhood environment attributes and CVDs and risk factors. Prevention programs should account for neighborhood environmental attributes in the communities where people live.

Analyses of Public Utility Building - Students Designs, Aimed at their Energy Efficiency Improvement

Science.gov (United States)

Wołoszyn, Marek Adam

2017-10-01

Public utility buildings are formally, structurally and functionally complex entities. Frequently, the process of their design involves the retroactive reconsideration of energy engineering issues, once a building concept has already been completed. At that stage, minor formal corrections are made along with the design of the external layer of the building in order to satisfy applicable standards. Architecture students do the same when designing assigned public utility buildings. In order to demonstrate energy-related defects of building designs developed by students, the conduct of analyses was proposed. The completed designs of public utility buildings were examined with regard to energy efficiency of the solutions they feature through the application of the following programs: Ecotect, Vasari, and in case of simpler analyses ArchiCad program extensions were sufficient.

Kartika, H.

2018-03-01

The issue related to making mistake while learning such as negative emotion is found while students learn mathematics with the aid of a computer. When the computer output showed a mistake message, the students considered it as a computer software malfunction. Based on this issue, the writer designs an instructional model based on learning by mistake approach and which is Scilab assisted. The method used in this research is research design involving undergraduate students in matrix algebra courses. The data collected throught survey with questionnaire to gain feedback about the approach implemented. The data analyzed using quantitative descriptive. The instructional design proposed is the student act as a mistake corrector while the teacher acts as a mistake maker. Teacher deliberately makes mistakes with the help of Scilab software. On the other hand, students correct, analyze and explain errors resulting from Scilab software. The result of this research is an ICT based instructional design which is expected to be applicable as an alternative learning in directing students to think positively about mistakes in learning. Furthermore, students are also expected to improve their ability in understanding and thinking critically while solving problems and improving themselves in learning mathematics.

Designing and implementing a physiology course for a new doctoral occupational therapy program with student feedback.

Goodman, Barbara E; Ikiugu, Moses N

2017-09-01

Recently, the Occupational Therapy Department requested a custom-designed medical physiology course for the students in the new occupational therapy doctoral program. The first author, a physiologist with extensive experience in teaching both undergraduate preprofessional and medical students in human physiology, was recruited to design and implement the course. The course was designed to be consistent with the constructivist philosophy that guides the occupational therapy curriculum. The course was offered for the first time during fall/spring 2015/2016 and included both first- and second-year occupational therapy doctoral students. A number of anonymous assessment tools were used to evaluate students' perceptions regarding the effectiveness of various pedagogies used in the course in enhancing their learning. A summative course assessment survey with comments was used at the end of the course. This paper describes the model of course design and the student feedback, which generated some suggestions for improvement of the course. This approach in designing a new course for a new disciplinary group of students should be helpful to other faculty involved in developing courses for health career programs populated by students with variable physiology backgrounds and different educational needs. The final relevant feedback from the course would be to have the students evaluate the usefulness of the course to their future careers immediately following their certification examinations in a year or two and during their subsequent clinical experiences; however, that information will likely be more difficult to obtain.

Engineering education for youth: Diverse elementary school students' experiences with engineering design

Science.gov (United States)

Hegedus, Theresa

Lingering concerns over the persistent achievement gap amidst the trend of an increasingly diverse society have been compounded by calls from the Oval Office, the National Science Board, and nationwide media to also address our current creativity crisis. Now, more than ever, we have a responsibility to produce a STEM-capable (science, technology, engineering, and mathematics) workforce to meet the demands of our rapidly changing local and global economic landscape. Barriers exist in our traditional educational system, which has historically limited underrepresented groups' affiliation and membership in the disciplines of science and engineering. The recent incorporation of engineering into the latest science education reform efforts presents an opportunity to expose students as early as elementary school to engineering practices and habits of mind, which have the potential to stimulate creative thinking skills through engineering design. This qualitative study was designed to examine the ways in which engineering education has the potential to promote creativity and academic competence in elementary science classrooms. As a part of my study, a diverse group of students from two fifth-grade classrooms took part in a 10-12 hour, engineering-based curriculum unit (Engineering is Elementary) during their regular science instructional time. Using a sociocultural lens, to include cultural production and identities in practice as part of my framework, I analyzed group and individual performances through classroom observations, student interviews, and teacher reflections to better understand the meaning students made of their experiences with engineering. Findings from the study included the ways in which creativity was culturally produced in the classroom to include: 1) idea generation; 2) design and innovation; 3) gumption/resourcefulness; and 4) social value. Opportunities for collaboration increased through each stage of the unit culminating with the design challenge

Attributes of the built environment can positively influence physical activity of urban populations, which results in health and economic benefits. In this study, we derived scenarios from the literature for the association built environment-physical activity and used a mathematical model to translate improvements in physical activity to health-adjusted life years and health care costs. We modelled 28 scenarios representing a diverse range of built environment attributes including density, diversity of land use, availability of destinations, distance to transit, design and neighbourhood walkability. Our results indicated potential health gains in 24 of the 28 modelled built environment attributes. Health care cost savings due to prevented physical activity-related diseases ranged between A$1300 to A$105,355 per 100,000 adults per year. On the other hand, additional health care costs of prolonged life years attributable to improvements in physical activity were nearly 50% higher than the estimated health care costs savings. Our results give an indication of the potential health benefits of investing in physical activity-friendly built environments. Copyright © 2016 Elsevier Ltd. All rights reserved.

In curbing physical inactivity, as behavioural interventions directed at individuals have not produced a population-level change, an ecological perspective called active living research has gained prominence. However, active living research consistently underexplores the role played by a perennial phenomenon encompassing all other environmental exposures-variation in weather. After factoring in weather variation, this study investigated the influence of diverse environmental exposures (including urban design and built environment) on the accumulation of globally recommended moderate to vigorous physical activity levels (MVPA) in children. This cross-sectional observational study is part of an active living initiative set in the Canadian prairie city of Saskatoon. As part of this study, Saskatoon's neighbourhoods were classified based on urban street design into grid-pattern, fractured grid-pattern and curvilinear types of neighbourhoods. Moreover, diverse environmental exposures were measured including, neighbourhood built environment, and neighbourhood and household socioeconomic environment. Actical accelerometers were deployed between April and June 2010 (spring-summer) to derive MVPA of 331 10-14-year-old children in 25 1-week cycles. Each cycle of accelerometry was conducted on a different cohort of children within the total sample and matched with weather data obtained from Environment Canada. Multilevel modelling using Hierarchical Linear and Non-linear Modelling software was conducted by factoring in weather variation to depict the influence of diverse environmental exposures on the accumulation of recommended MVPA. Urban design, including diversity of destinations within neighbourhoods played a significant role in the accumulation of MVPA. After factoring in weather variation, it was observed that children living in neighbourhoods closer to the city centre (with higher diversity of destinations) were more likely to accumulate recommended MVPA. The findings

2018-03-01

The purpose of this study was to determine the influence of computer-aided design (CAD) software-based instruction on the spatial visualisation skills of freshman engineering students in a computer-aided engineering drawing course. A quasi-experimental design was applied, using the Purdue Spatial Visualization Test-Visualization of Rotations (PSVT:R) for both the pre- and the post-test. The participants were 116 freshman students in the first year of their undergraduate programme in the Department of Mechanical Engineering at a university in Turkey. A total of 72 students comprised the experimental group; they were instructed with CAD-based activities in an engineering drawing course. The control group consisted of 44 students who did not attend this course. The results of the study showed that a CAD-based engineering drawing course had a positive effect on developing engineering students' spatial visualisation skills. Additionally, the results of the study showed that spatial visualisation skills can be a predictor for success in a computer-aided engineering drawing course.

Full Text Available The formation of national identity is the essence for a multi-racial country like Malaysia because it can strengthen national solidarity, create a common aspiration, and sustain the continuity of a historical heritage with multiple ethnicity and background. Nevertheless, the characteristics of this national identity is still not fully dealt with from an architectural aspect. Hence, the purpose of this paper is to critically examine the problem of national architectural identity in Malaysia. This is vital to uncover the resulting design principles with national architectural identity characteristics by referencing to three typologies of local state mosque as case study. The finding outlines that there are six architectural principles that influence the formation of national identity. These are the understanding of built form detail elements, materials usage, local style composition and expression, application of organic theory, designing a regionalistic articulation of space and form as well as an understanding of democratic values form to reflect the characteristics of national identity. These established referential guideline design on national identity is of benefit for future designers, builders, developer and related authority to produce built form that symbolizes nation political values as well as responsive to the existing social culture context.

Biel, Rachel; Brame, Cynthia J

2016-12-01

Online courses are a large and growing part of the undergraduate education landscape, but many biology instructors are skeptical about the effectiveness of online instruction. We reviewed studies comparing the effectiveness of online and face-to-face (F2F) undergraduate biology courses. Five studies compared student performance in multiple course sections at community colleges, while eight were smaller scale and compared student performance in particular biology courses at a variety of types of institutions. Of the larger-scale studies, two found that students in F2F sections outperformed students in online sections, and three found no significant difference; it should be noted, however, that these studies reported little information about course design. Of the eight smaller scale studies, six found no significant difference in student performance between the F2F and online sections, while two found that the online sections outperformed the F2F sections. In alignment with general findings about online teaching and learning, these results suggest that well-designed online biology courses can be effective at promoting student learning. Three recommendations for effective online instruction in biology are given: the inclusion of an online orientation to acclimate students to the online classroom; student-instructor and student-student interactions facilitated through synchronous and asynchronous communication; and elements that prompt student reflection and self-assessment. We conclude that well-designed online biology courses can be as effective as their traditional counterparts, but that more research is needed to elucidate specific course elements and structures that can maximize online students' learning of key biology skills and concepts.

A new vision of management competencies built in Business Simulations

Directory of Open Access Journals (Sweden)

Gabriel Vianna Schlatter

2015-09-01

Full Text Available This paper presents a survey conducted on users of an online business simulation for an undergraduate Business Administration course. Previous research on the use of business simulations described the validity of this resource as a method for developing managerial skills, as well as the perceptions of students about the experience. However, few studies sought to directly assess which management competencies are built through the use of simulators. In this study, students expressed their perception of the management competencies developed by participating in the simulation. The survey was structured according to the macro-competencies proposed by the Tuning Latin America Project and identified those with higher and lower perceived development.  It was found that the simulation was useful in building up competencies related to the use of information to support decision-making, management of company resources at the operational level and the identification and management of business risks. Moreover, it was possible to determine through factor analysis that the construction of various competencies occurred simultaneously, creating more elaborate assemblies. Five sets, composed of several competencies, have been identified and described as: carrying out undertakings based on data and facts; managing organization´s processes and projects; developing their own planning process; acting primarily with social responsibility; and, managing change risks through teamwork.

Peer review in design: Understanding the impact of collaboration on the review process and student perception

Science.gov (United States)

Mandala, Mahender Arjun

A cornerstone of design and design education is frequent situated feedback. With increasing class sizes, and shrinking financial and human resources, providing rich feedback to students becomes increasingly difficult. In the field of writing, web-based peer review--the process of utilizing equal status learners within a class to provide feedback to each other on their work using networked computing systems--has been shown to be a reliable and valid source of feedback in addition to improving student learning. Designers communicate in myriad ways, using the many languages of design and combining visual and descriptive information. This complex discourse of design intent makes peer reviews by design students ambiguous and often not helpful to the receivers of this feedback. Furthermore, engaging students in the review process itself is often difficult. Teams can complement individual diversity and may assist novice designers collectively resolve complex task. However, teams often incur production losses and may be impacted by individual biases. In the current work, we look at utilizing a collaborative team of reviewers, working collectively and synchronously, in generating web based peer reviews in a sophomore engineering design class. Students participated in a cross-over design, conducting peer reviews as individuals and collaborative teams in parallel sequences. Raters coded the feedback generated on the basis of their appropriateness and accuracy. Self-report surveys and passive observation of teams conducting reviews captured student opinion on the process, its value, and the contrasting experience they had conducting team and individual reviews. We found team reviews generated better quality feedback in comparison to individual reviews. Furthermore, students preferred conducting reviews in teams, finding the process 'fun' and engaging. We observed several learning benefits of using collaboration in reviewing including improved understanding of the assessment

Behavior mapping showed that site layout attributes, such as the form (i.e., "single loop" and "double loop") of pathways (functioning as circulation routes and wheeled toy settings), are associated with higher levels of PA. Teacher interaction was associated with decreased children's PA. Absence of teacher or lack of child/child interaction was associated with increased PA. POEMS assessment of environmental quality was higher after renovation. POEMS domains (Physical Space and Teacher/Caregiver Roles) were positively associated with PA. After renovation, 68% of center directors reported positive changes in children's behavior and 40% mentioned edible plant installations as greatest success. Built environment renovation of childcare center outdoors, including looped pathways installation, coupled with teacher training, may support increased PA. Renovation, including food gardens, may be a key to success for preschool health promotion and support change in childcare policy.

Research highlights in energy and eco-efficient built environment

Energy Technology Data Exchange (ETDEWEB)

Airaksinen, M. (ed.)

2012-06-15

This publication presents a compilation of VTT's recent research on energy and eco-efficient built environment. Sustainability as a dominating driver of technology development can also be seen in the R and D portfolio of VTT Technical Research Centre of Finland. A clear focus of our research for the building sector is sustainable construction, particularly the energy efficiency of the built environment. Buildings and the whole built environment are in a key role when societies are mitigating climate change and adapting to its consequences. Despite the temporary economic downturn, construction globally remains one of the most significant areas of human activities globally. Due to the urgency of measures related to climate change and the need to provide a proper environment for living and working, a large number of national and international measures have been agreed to guarantee the future development of sustainable built environment for all. Indirectly, this has lead to a need to develop existing and completely new technologies and processes for the built environment with a speed faster than ever and with a more holistic performance metrics than ever.

Computational simulations of frictional losses in pipe networks confirmed in experimental apparatusses designed by honors students

Science.gov (United States)

Pohlman, Nicholas A.; Hynes, Eric; Kutz, April

2015-11-01

Lectures in introductory fluid mechanics at NIU are a combination of students with standard enrollment and students seeking honors credit for an enriching experience. Most honors students dread the additional homework problems or an extra paper assigned by the instructor. During the past three years, honors students of my class have instead collaborated to design wet-lab experiments for their peers to predict variable volume flow rates of open reservoirs driven by gravity. Rather than learn extra, the honors students learn the Bernoulli head-loss equation earlier to design appropriate systems for an experimental wet lab. Prior designs incorporated minor loss features such as sudden contraction or multiple unions and valves. The honors students from Spring 2015 expanded the repertoire of available options by developing large scale set-ups with multiple pipe networks that could be combined together to test the flexibility of the student team's computational programs. The engagement of bridging the theory with practice was appreciated by all of the students such that multiple teams were able to predict performance within 4% accuracy. The challenges, schedules, and cost estimates of incorporating the experimental lab into an introductory fluid mechanics course will be reported.

Intensifying the proportion of urban green infrastructure has been considered as one of the remedies for air pollution levels in cities, yet the impact of numerous vegetation types deployed in different built environments has to be fully synthesised and quantified. This review examined published literature on neighbourhood air quality modifications by green interventions. Studies were evaluated that discussed personal exposure to local sources of air pollution under the presence of vegetation in open road and built-up street canyon environments. Further, we critically evaluated the available literature to provide a better understanding of the interactions between vegetation and surrounding built-up environments and ascertain means of reducing local air pollution exposure using green infrastructure. The net effects of vegetation in each built-up environment are also summarised and possible recommendations for the future design of green infrastructure are proposed. In a street canyon environment, high-level vegetation canopies (trees) led to a deterioration in air quality, while low-level green infrastructure (hedges) improved air quality conditions. For open road conditions, wide, low porosity and tall vegetation leads to downwind pollutant reductions while gaps and high porosity vegetation could lead to no improvement or even deteriorated air quality. The review considers that generic recommendations can be provided for vegetation barriers in open road conditions. Green walls and roofs on building envelopes can also be used as effective air pollution abatement measures. The critical evaluation of the fundamental concepts and the amalgamation of key technical features of past studies by this review could assist urban planners to design and implement green infrastructures in the built environment.

Human Behavior and Environmental Sustainability: promoting a pro-environmental behavior by harnessing the social, psychological and physical influences of the built environment

Science.gov (United States)

Abusafieh, Shaden; Razem, Maiss

2017-11-01

Recently, technological advancements in the sustainable design field have allowed us to reduce the ecological impact of the built environment, to reduce consumption of non-renewable resources, to create healthy environments and in some cases may even rehabilitate the ecosystem. Nevertheless, several studies have been carried out showing that sustainable technology does not automatically lead to environmentally friendly behaviors in its users. Various environmental problems threaten environmental sustainability and many of these problems are rooted in human behavior. Unfortunately, there is a lack in studies which take into consideration the human behavior influences within a sustainable built environment. We believe that the built environment should be used to support human goals and requirements, but at the same time we should consider it as a context in which human values and behaviors are cultivated. This research aimed to help in promoting environmental sustainability by using architectural design in changing relevant human behavior toward an environmentally friendly behavior. In order to achieve this, the research adopted Environment-centered Approach to gain more acute perspective into the relationship between the physical environment and human behavior, focusing on social, psychological and physical influences of the built environment. It appears that environmental psychology's merits have high potential in changing behavior within the built environment. The research provides a systematic approach for selecting, assessing, evaluating the behaviors to be changed and the factors that determine them. Furthermore, this approach helps in choosing the best interventions that could be applied in built environment to encourage such a sustainable behavior. This study tried to construct an agenda for further researches to find particular architectural design elements and strategies that we can harness to develop a pro-environment human behavior.

Directory of Open Access Journals (Sweden)

Magdalena VELCIU

2017-05-01

Full Text Available Romanian youth migration is an increasing phenomenon, due to subjective and objective factors as economical reasons, professional carrer and increasingly more international competition for talent. In these circumstances, the present article aims to evaluate determinant factors that contribute to the decision of Romanian graduates to return national labour market. We sustain that young Romanians consider carefully and hardly decide their professional future. A particular attention is given to their personal reasons and motivations as well as family and friends network. For designing returning factors we present the results of a questionnaire survey, asking young pupils and students about their future educational way and personal reasons underlying the decision to study in a foreign country and taking into consideration the returning decision. As far international student migration is seen as a first step to migration for work, our work desires to fight for returning home of Romanian well-educated graduates.

O'Connor, Siobhan; Andrews, Tom

2016-01-01

Mobile technology is being trialed in nursing education to support students in clinical practice, as it can provide instant access to high quality educational material at the point of care. However, most educational mobile apps are generic, off-the-shelf applications that do not take into consideration the unique needs of nursing students, who can require personalised software solutions. This study adapted a socio-cognitive engineering approach and through a series of focus groups with final year nursing students explored the co-design process and gained their input on the design and functionality of a clinical skills based educational app. Results showed students required an uncluttered interface that was fast to navigate and easy to use in busy clinical environments. They also requested simple visual descriptions of key clinical skills and equipment to enable them to quickly refresh their memory so they could perform the skill in practice.

A tool to assess the built environment, which takes into account issues of disability, accessibility and the need for data comparable across countries and populations, is much needed. The Collaborative Research on Ageing in Europe (COURAGE) in Europe Built Environment Outdoor Checklist (CBE-OUT) helps us to understand when features of the neighbourhood environment have either a positive or negative impact on the accessibility of neighbourhoods for healthy ageing. The CBE-OUT is composed of 128 items that can be recorded when present in the evaluated environment. Audits were performed in households randomly selected from each cluster of the sample for Finland, Poland and Spain, following precise rules defined by experts. Global scores were computed both section by section and in the overall checklist, rescaling the resulting scores from 0 (negative environment) to 100 (positive). The total number of completed CBE-OUT checklists was 2452 (Finland, 245; Poland, 972; and Spain, 1235). Mean global score for our sample is 49.3, suggesting an environment composed both of facilitating and hindering features. Significant differences were observed in the built environment features of the three countries and in particular between Finland and the other two. The assessment of features of built environment is crucial when thinking about ageing and enhanced participation. The COURAGE in Europe project developed this tool to collect information on built environment in an objective evaluation of environmental features and is a recommended methodology for future studies. The CBE-OUT checklist is an objective evaluation of the built environment and is centred on technical measurement of features present in the environment and has its foundations in the concepts of disability and accessibility operating in the International Classification of Functioning, Disability and Health (ICF) model. The CBE-OUT checklist can be analysed using both the total score and the single section score

2014-07-01

Adding ultrasonic vibrations to drilling process results in an advanced hybrid machining process, entitled "vibration drilling". This study presents the design and fabrication of a vibration drilling tool by which both rotary and vibrating motions are applied to drill simultaneously. High frequency and low amplitude vibrations were generated by an ultrasonic transducer with frequency of 19.65 kHz. Ultrasonic transducer was controlled by a MPI ultrasonic generator with 3 kW power. The drilling tool and workpiece material were HSS two-flute twist drill and Al2024-T6, respectively. The aim of this study was investigating on the effect of ultrasonic vibrations on built-up edge, surface quality, chip morphology and wear mechanisms of drill edges. Therefore, these factors were studied in both vibration and ordinary drilling. Based on the achieved results, vibration drilling offers less built-up edge and better surface quality compared to ordinary drilling. Copyright © 2014 Elsevier B.V. All rights reserved.

Product archaeology as an educational approach asks engineering students to consider and explore the broader societal and global impacts of a product's manufacturing, distribution, use, and disposal on people, economics, and the environment. This study examined the impact of product archaeology in a project-based engineering design course on student attitudes and perceptions about engineering and abilities to extend and refine knowledge about broader contexts. Two design scenarios were created: one related to dental hygiene and one related to vaccination delivery. Design scenarios were used to (1) assess knowledge of broader contexts, and (2) test variability of student responses across different contextual situations. Results from pre- to post-surveying revealed improved student perceptions of knowledge of broader contexts. Significant differences were observed between the two design scenarios. The findings support the assumption that different design scenarios elicit consideration of different contexts and design scenarios can be constructed to target specific contextual considerations.

The house that Abdus built...The ICTP in Trieste

International Nuclear Information System (INIS)

Roederer, J.G.

2006-01-01

The Abdus Salam International Centre for Theoretical Physics stems the brain drain of physicists from developing nations at a time of new scientific challenges. Abdus Salam, a Nobel Prize-winning Pakistani physicist, recognized that improving science locally would not be enough to stem the flight of fledgling scientists from developing countries. International mechanisms would be needed to allow scientists - especially those returning home after training abroad - to stay connected with the world, to refresh their knowledge periodically, and to engage in international research collaborations. The time was right for the conception of an international centre for theoretical physics. In 1964 under the aegis of the IAEA, the Abdus Salam International Centre for Theoretical Physics (ICTP) was intended to be not just another international research institute. The intention was a model organization designed to promote training and research in the physical and mathematical sciences in developing countries; serve as a forum for scientists from all over the world; and operate as a first-class scientific institution. All three goals reflect the desire of its founding director, Abdus Salam, to confront the issues of isolation and brain drain that have continually dimmed the prospects for scientific excellence across the developing world. Today ICTP each year hosts some 6000 scientists in its facilities in Trieste, Italy, while maintaining strong and enduring links with scientific communities in more than 170 countries. Closer to home, it has forged cooperative relationship with many Italian scientific institutions. Through its efforts, the Centre has built a worldwide family of loyal alumni, tens of thousands of associates, lecturers, and students, many of whom are now internationally recognized scientists, university leaders, research-council presidents, and leading statesmen in their own countries

A recent focus of design and building regulations, including form-based codes and the Leadership in Energy and Environmental Design for Neighborhood Development rating system, has been on promoting pedestrian activity. This study assessed perceptions of walkability for residential and commercial streetscapes with different design attributes in order to inform form-based regulations and codes that aim to impact walkability. We scored 424 images on four design attributes purported to influence walkability: variation in building height, variation in building plane, presence of ground-floor windows, and presence of a street focal point. We then presented the images to 45 adults, who were asked to rate the images for walkability. The results showed that perceived walkability varied according to the degree to which a particular design attribute was present, with the presence of ground-floor windows and a street focal point most consistently associated with a space's perceived walkability. Understanding if and which design attributes are most related to walkability could allow planners and developers to focus on the most salient built-environment features influencing physical activity, as well as provide empirical scientific evidence for form-based regulations and zoning codes aimed at impacting walkabilit.

Engaging Students In Modeling Instruction for Introductory Physics

Science.gov (United States)

Brewe, Eric

2016-05-01

Teaching introductory physics is arguably one of the most important things that a physics department does. It is the primary way that students from other science disciplines engage with physics and it is the introduction to physics for majors. Modeling instruction is an active learning strategy for introductory physics built on the premise that science proceeds through the iterative process of model construction, development, deployment, and revision. We describe the role that participating in authentic modeling has in learning and then explore how students engage in this process in the classroom. In this presentation, we provide a theoretical background on models and modeling and describe how these theoretical elements are enacted in the introductory university physics classroom. We provide both quantitative and video data to link the development of a conceptual model to the design of the learning environment and to student outcomes.

Baker, D.

2006-12-01

As part of the NASA-supported undergraduate Earth System Science Education (ESSE) program, fifty-seven institutions have developed and implemented a wide range of Earth system science (ESS) courses, pedagogies, and evaluation tools. The Teaching, Learning, and Evaluation section of USRA's online ESSE Design Guide showcases these ESS learning environments. This Design Guide section also provides resources for faculty who wish to develop ESS courses. It addresses important course design issues including prior student knowledge and interests, student learning objectives, learning resources, pedagogical approaches, and assessments tied to student learning objectives. The ESSE Design Guide provides links to over 130 ESS course syllabi at introductory, senior, and graduate levels. ESS courses over the past 15 years exhibit common student learning objectives and unique pedagogical approaches. From analysis of ESS course syllabi, seven common student learning objectives emerged: 1) demonstrate systems thinking, 2) develop an ESS knowledge base, 3) apply ESS to the human dimension, 4) expand and apply analytical skills, 5) improve critical thinking skills, 6) build professional/career skills, and 7) acquire an enjoyment and appreciation for science. To meet these objectives, ESSE often requires different ways of teaching than in traditional scientific disciplines. This presentation will highlight some especially successful pedagogical approaches for creating positive and engaging ESS learning environments.

A Review of the As-Built SLM Ti-6Al-4V Mechanical Properties towards Achieving Fatigue Resistant Designs

Directory of Open Access Journals (Sweden)

Dylan Agius

2018-01-01

Full Text Available Ti-6Al-4V has been widely used in both the biomedical and aerospace industry, due to its high strength, corrosion resistance, high fracture toughness and light weight. Additive manufacturing (AM is an attractive method of Ti-6Al-4V parts’ fabrication, as it provides a low waste alternative for complex geometries. With continued progress being made in SLM technology, the influence of build layers, grain boundaries and defects can be combined to improve further the design process and allow the fabrication of components with improved static and fatigue strength in critical loading directions. To initiate this possibility, the mechanical properties, including monotonic, low and high cycle fatigue and fracture mechanical behaviour, of machined as-built SLM Ti-6Al-4V, have been critically reviewed in order to inform the research community. The corresponding crystallographic phases, defects and layer orientations have been analysed to determine the influence of these features on the mechanical behaviour. This review paper intends to enhance our understanding of how these features can be manipulated and utilised to improve the fatigue resistance of components fabricated from Ti-6Al-4V using the SLM technology.

Drawing upon a ‘student as partners’ framework, the presentation explored how this has been used to underpin an approach to peer mentoring from the ground up. University peer mentoring programs are largely designed and developed by staff, who not only recruit and train student mentors but also select frequency and type of involvement for all parties. This pilot project proposes a different approach by collaborating with students in the design, development and enactment of a peer-mentoring program within one School of Education. From this pilot, we will develop guidelines and recommendations for the implementation of student-led peer mentoring programs (Students as Partners in Mentoring: SaPiM across the University of Wollongong (UOW.

The effect of architectural façade design on energy savings in the student dormitory

Directory of Open Access Journals (Sweden)

Pejić Petar Č.

2014-01-01

Full Text Available There are many reasons for adequate use of natural light inside students' dormitories. Intensity of light required for student activities and temperature inside the rooms are the major factors for an occupant's comfortable work and life. Design of building façades has a significant impact both on the use of natural light and energy consumption. In this paper, a comparative analysis of student rooms with different orientations and different façade designs was performed in order to investigate what type of refurbishment in the façade is necessary. The goal of the refurbishment was generation of optimal thermal and lighting comfort for students' work with maximal energy saving for a new student dormitory in Nis, Serbia. An analysis of annual energy consumption of the newly designed student dormitory and proposed replacements on the exterior façade was performed by using the software EnergyPlus. Based on the energy consumption analysis it could be concluded that significant energy savings would be possible by upgrading the shading devices across the width of the window. In other words, changing the façade of the dorm could generally improve students' comfort, while the energy costs would be reduced. [Projekat Ministarstva nauke Republike Srbije, br.

To estimate the variation in the prevalence of common mental disorders attributable to individuals and the built environment of geographical sectors where they live. A sample of 3870 adults (response rate 90%) clustered in 248 geographical sectors participated in a household cross-sectional survey in Santiago, Chile. Independently rated contextual measures of the built environment were obtained. The Clinical Interview Schedule was used to estimate the prevalence of common mental disorders. There was a significant association between the quality of the built environment of small geographical sectors and the presence of common mental disorders among its residents. The better the quality of the built environment, the lower the scores for psychiatric symptoms; however, only a small proportion of the variation in common mental disorder existed at sector level, after adjusting for individual factors. Findings from our study, using a contextual assessment of the quality of the built environment and multilevel modelling in the analysis, suggest these associations may be more marked in non-Western settings with more homogeneous geographical sectors.

2014-07-08

Virtual patient (VP) cases are an effective teaching method, although little is known about how to design and implement them for maximum effectiveness. The aim of this study was to explore the effect of case design and teamwork on students' learning outcome. One hundred forty-six undergraduate medical students participated in a mandatory medical computer science course consisting of five seminars. At the end of each seminar, they worked on one VP case, either in teams of two or individually. Each student filled out an introductory and a final survey and a feedback sheet after completing each case. Additionally, there was a surprise multiple choice (MC) test after the last seminar with three questions regarding each case. Students with more clinical experience and students who had worked in a team performed significantly better on MC questions. Students with less clinical experience more frequently used information which had been positioned less prominently on the case material. Certain aspects of case design were rated more positively by students who had an interest in e-learning. In general, students preferred to work on cases for less than 15 minutes. Clinically more advanced students and students working with a partner seem to benefit most from short VP cases with prominently presented information.

Grealish, Laurie A; Shaw, Julie M

Assessment technologies are often used to classify student and newly qualified nurse performance as 'pass' or 'fail', with little attention to how these decisions are achieved. Examining the design exigencies of classification technologies, such as performance assessment technologies, provides opportunities to explore flexibility and change in the process of using those technologies. Evaluate an established assessment technology for nursing performance as a classification system. A case study analysis that is focused on the assessment approach and a priori design exigencies of performance assessment technology, in this case the Australian Nursing Standards Assessment Tool 2016. Nurse assessors are required to draw upon their expertise to judge performance, but that judgement is described as a source of bias, creating confusion. The definition of satisfactory performance is 'ready to enter practice'. To pass, the performance on each criterion must be at least satisfactory, indicating to the student that no further improvement is required. The Australian Nursing Standards Assessment Tool 2016 does not have a third 'other' category, which is usually found in classification systems. Introducing a 'not yet competent' category and creating a two-part, mixed methods assessment process can improve the Australian Nursing Standards Assessment Tool 2016 assessment technology. Using a standards approach in the first part, judgement is valued and can generate learning opportunities across a program. Using a measurement approach in the second part, student performance can be 'not yet competent' but still meet criteria for year level performance and a graded pass. Subjecting the Australian Nursing Standards Assessment Tool 2016 assessment technology to analysis as a classification system provides opportunities for innovation in design. This design innovation has the potential to support students who move between programs and clinicians who assess students from different

Perceptions of undergraduate Graphic Design students on the educational potential of Facebook

Full Text Available The popularity of Facebook among university students inevitably raises questions on the educational potential of this Social Networking Site for Higher Education. From the limited literature on the instructional uses of Facebook, one can draw conflicting conclusions. Benefits were identified through the communicative potential, student participation in study groups and through informal learning, i.e. learning that takes place outside the formal structures of the learning environment. In contrast, it is also argued that the instructional benefits of Facebook are not straightforward. This phenomenographic investigation examines the perceptions of undergraduate Graphic Design students in a higher education institution in Cyprus, on the use of Facebook for teaching and learning. Characteristic of Art and Design education is the centrality of the studio and student self-reflection. Despite some literature that considers Facebook provides a viable alternative to the physical studio, the participants in this investigation expressed a preference for face-to-face instruction and consider Facebook as complimenting rather than replacing studio practices. Some participants benefited from the use of Facebook by joining support groups and exploring information relevant to their studies. Further research can investigate how Facebook can be embedded in studio-based teaching and learning.

Roche, Maya; Adiga, Indira Kakkunje; Nayak, Akshatha G

2016-12-01

Problem Based Learning (PBL) is known world over as an effective, active learning strategy with many benefits for the student. Usually, in medical schools, PBL triggers are designed by a well-trained group of faculty from basic and clinical sciences. The challenge was whether this task could be given to students in the first year of their curriculum and be executed by them effectively. To enhance active learning, comprehension and critical thinking with a view to promote horizontal and vertical integration between subjects. Student volunteers of the first year MBBS course (n=10), who had been exposed to the curriculum for approximately 38 weeks and were familiar with the PBL process were recruited for the study. In addition to a handout on the topic 'gout', they were given the freedom to access any resource in the university library to construct the PBL triggers. The PBL triggers were vetted by two faculties. In addition to a focus group discussion with students, students' and faculty's responses were collected on a Likert scale. Students opined that the exercise helped improve their comprehension (100%), critical thinking abilities (90%) and clinical orientation to the topic (100%). They felt that designing a PBL trigger was a relevant active learning strategy (100%) and would help them answer questions on this topic better in the future (90%). The clinicians who examined the PBL triggers, felt that they were of good quality and that the process was a good tool for vertical integration between basic and clinical sciences. The results prove that students when given a challenge will rise to the occasion. Unfamiliarity with the nuances of a disease did not prevent them from going the extra mile to achieve their target. By taking part in this exercise, students benefitted in many ways and got a holistic understanding of the topic. PBL trigger design can be introduced as an active learning strategy for students in medical schools where PBL is part of the curriculum. It

Built Environment Influences of Children’s Physical Activity: Examining Differences by Neighbourhood Size and Sex

Full Text Available Neighbourhoods can facilitate or constrain moderate-to-vigorous physical activity (MVPA among children by providing or restricting opportunities for MVPA. However, there is no consensus on how to define a child’s neighbourhood. This study examines the influence of the neighbourhood built environment on objectively measured MVPA among 435 children (aged 9–14 years in London (ON, Canada. As there is no consensus on how to delineate a child’s neighbourhood, a geographic information system was used to generate measures of the neighbourhood built environment at two buffer sizes (500 m and 800 m around each child’s home. Linear regression models with robust standard errors (cluster were used to analyze the relationship between built environment characteristics and average daily MVPA during non-school hours on weekdays. Sex-stratified models assessed sex-specific relationships. When accounting for individual and neighbourhood socio-demographic variables, park space and multi-use path space were found to influence children’s MVPA. Sex-stratified models found significant associations between MVPA and park space, with the 800 m buffer best explaining boys’ MVPA and the 500 m buffer best explaining girls’ MVPA. Findings emphasize that, when designing built environments, programs, and policies to facilitate physical activity, it is important to consider that the size of the neighbourhood influencing a child’s physical activity may differ according to sex.

Asthma in the community: Designing instruction to help students explore scientific dilemmas that impact their lives

Science.gov (United States)

Tate, Erika Dawn

School science instruction that connects to students' diverse home, cultural, or linguistic experiences can encourage lifelong participation in the scientific dilemmas that impact students' lives. This dissertation seeks effective ways to support high school students as they learn complex science topics and use their knowledge to transform their personal and community environments. Applying the knowledge integration perspective, I collaborated with education, science, and community partners to design a technology enhanced science module, Improving Your Community's Asthma Problem. This exemplar community science curriculum afforded students the opportunity to (a) investigate a local community health issue, (b) interact with relevant evidence related to physiology, clinical management, and environmental risks, and (c) construct an integrated understanding of the asthma problem in their community. To identify effective instructional scaffolds that engage students in the knowledge integration process and prepare them to participate in community science, I conducted 2 years of research that included 5 schools, 10 teachers, and over 500 students. This dissertation reports on four studies that analyzed student responses on pre-, post-, and embedded assessments. Researching across four design stages, the iterative design study investigated how to best embed the visualizations of the physiological processes breathing, asthma attack, and the allergic immune response in an inquiry activity and informed evidence-based revisions to the module. The evaluation study investigated the impact of this revised Asthma module across multiple classrooms and differences in students' prior knowledge. Combining evidence of student learning from the iterative and evaluation studies with classroom observations and teacher interviews, the longitudinal study explored the impact of teacher practices on student learning in years 1 and 2. In the final chapter, I studied how the Asthma module and

Photocatalytic oxide films in the built environment

The possibility to increase human comfort in buildings is a powerful driving force for the introduction of new technology. Among other things our sense of comfort depends on air quality, temperature, lighting level, and the possibility of having visual contact between indoors and outdoors. Indeed there is an intimate connection between energy, comfort, and health issues in the built environment, leading to a need for intelligent building materials and green architecture. Photocatalytic materials can be applied as coatings, filters, and be embedded in building materials to provide self-cleaning, antibacterial, air cleaning, deodorizing, and water cleaning functions utilizing either solar light or artificial illumination sources - either already present in buildings, or by purposefully designed luminaries. Huge improvements in indoor comfort can thus be made, and also alleviate negative health effects associated with buildings, such as the sick-house syndrome. At the same time huge cost savings can be made by reducing maintenance costs. Photocatalytic oxides can be chemically modified by changing their acid-base surface properties, which can be used to overcome deactivation problems commonly encountered for TiO2 in air cleaning applications. In addition, the wetting properties of oxides can be tailored by surface chemical modifications and thus be made e.g. oleophobic and water repellent. Here we show results of surface acid modified TiO2 coatings on various substrates by means of photo-fixation of surface sulfate species by a method invented in our group. In particular, we show that such surface treatments of photocatalytic concrete made by mixing TiO2 nanoparticles in reactive concrete powders result in concrete surfaces with beneficial self-cleaning properties. We propose that such approaches are feasible for a number of applications in the built environment, including glass, tiles, sheet metals, plastics, etc.

Full Text Available This paper is concerned with the identification of different influences on the built environment, and those which have a physical and psychological impact on people. The aim of this study is to analyze the impact of the built environment on the lives of people. The interrelationship between people and built environment is based on human perception. This research will explore this relationship further in order to develop a clear understanding of the ways in which architecture may influence peoples’ perceptions and experiences. Additionally, the research entails a comparison between two important theories: the first is an Image of the city derived using the Mental Map Theory; the second is related to Space Syntax Theory. The two theories will be applied in two different cities in Libya with the aim of assessing the importance of their interrelationship and how it may be understood more clearly. This paper will also provide guidelines for improving urban design and planning standards with the end goal of producing a high quality perception by those who actually use the space. Moreover, it concludes with a number of research avenues that should be pursued to answer how the properties of built environment affect human perception.

STEM Learning focusses on development of STEM-literate society, the research about implementation of STEM learning to develope students’ STEM literacy is still limited. This study is aimed to examine the effect of implementation STEM learning through the project of designing boat model on students STEM literacy in energy topic. The method of this study was a quasi-experiment with non-randomized pretest-posttest control group design. There were two classes involved, the experiment class used Project Based Learning with STEM approach and control class used Project-Based Learning without STEM approach. A STEM Literacy test instrument was developed to measure students STEM literacy which consists of science literacy, mathematics literacy, and technology-engineering literacy. The analysis showed that there were significant differences on improvement science literacy, mathematics technology-engineering between experiment class and control class with effect size more than 0.8 (large effect). The difference of improvement of STEM literacy between experiment class and control class is caused by the existence of design engineering activity which required students to apply the knowledge from every field of STEM. The challenge that was faced in STEM learning through design engineering activity was how to give the students practice to integrate STEM field in solving the problems. In additional, most of the students gave positive response toward implementation of STEM learning through design boat model project.

Engaging College Students at Two-year Campuses in Aerospace Research

2018-01-01

College students at two-year campuses have unique challenges to their learning and are often "nontraditional" students, including first-generation and/or returning adult students. They have little or no exposure to research, related to science and aerospace or otherwise, and so they do not think of these fields as possible careers or understand how the disciplines operate. Exposing these students to real research projects, especially ones that include rocket payloads, have a dramatic effect on the interests and academic success of students. Projects such as these can be quite large and expensive, perhaps prohibitively so for small institutions. We engaged a group of these students through the RockOn and RockSat programs lead by the Colorado Space Grant Consortium, which are programs for postsecondary students to access space with relatively easy access and low cost. The student team designed, built, and flew a scientific payload on a suborbital sounding rocket launched at NASA's Wallops Flight Facility in Virginia. The experiment sent E. coli DNA samples into space to assess the damage and measured the radiation exposure with and without radiation shielding, and assessed the samples for DNA damage upon their return. We report on the process and the effects on the students as part of their experience.

A studentized permutation test for three-arm trials in the 'gold standard' design.

Science.gov (United States)

Mütze, Tobias; Konietschke, Frank; Munk, Axel; Friede, Tim

2017-03-15

The 'gold standard' design for three-arm trials refers to trials with an active control and a placebo control in addition to the experimental treatment group. This trial design is recommended when being ethically justifiable and it allows the simultaneous comparison of experimental treatment, active control, and placebo. Parametric testing methods have been studied plentifully over the past years. However, these methods often tend to be liberal or conservative when distributional assumptions are not met particularly with small sample sizes. In this article, we introduce a studentized permutation test for testing non-inferiority and superiority of the experimental treatment compared with the active control in three-arm trials in the 'gold standard' design. The performance of the studentized permutation test for finite sample sizes is assessed in a Monte Carlo simulation study under various parameter constellations. Emphasis is put on whether the studentized permutation test meets the target significance level. For comparison purposes, commonly used Wald-type tests, which do not make any distributional assumptions, are included in the simulation study. The simulation study shows that the presented studentized permutation test for assessing non-inferiority in three-arm trials in the 'gold standard' design outperforms its competitors, for instance the test based on a quasi-Poisson model, for count data. The methods discussed in this paper are implemented in the R package ThreeArmedTrials which is available on the comprehensive R archive network (CRAN). Copyright © 2016 John Wiley & Sons, Ltd.

Teaching Experiences for Graduate Student Researchers: A Study of the Design and Implementation of Science Courses for Secondary Students

Science.gov (United States)

Collins, Anne Wrigley

Modern science education reform recommends that teachers provide K-12 science students a more complete picture of the scientific enterprise, one that lies beyond content knowledge and centers more on the processes and culture of scientists. In the case of Research Experience for Teachers (RET) programs, the "teacher" becomes "researcher" and it is expected that he/she will draw from the short-term science research experience in his/her classroom, offering students more opportunities to practice science as scientists do. In contrast, this study takes place in a program that allows graduate students, engaged in research full-time, to design and implement a short-duration course for high school students on Saturdays; the "researcher" becomes "teacher" in an informal science program. In this study, I investigated eleven graduate students who taught in the Saturday Science (SS) program. Analyses revealed participants' sophisticated views of the nature of science. Furthermore, participants' ideas about science clearly resonated with the tenets of NOS recommended for K-12 education (McComas et al., 1998). This study also highlighted key factors graduate students considered when designing lessons. Instructors took great care to move away from models of traditional, "lecture"-based, university science teaching. Nonetheless, instruction lacked opportunities for students to engage in scientific inquiry. In instances when instructors included discussions of NOS in SS courses, opportunities for high school students to learn NOS were not explicit enough to align with current science reform recommendations (e.g., AAAS, 2009). Graduate students did, however, offer high school students access to their own science or engineering research communities. These findings have significant implications for K-12 classroom reform. Universities continue to be a valuable resource for K-12 given access to scientists, materials or equipment, and funding. Nonetheless, and as was the case with

Climate change is one of the most pressing challenges facing society, and climate change educational models are emerging in response. This study investigates the implementation and enactment of a climate change professional development model for science educators and its impact on student learning. Using an intrinsic case study methodology, we focused analytic attention on how one teacher made specific curricular, pedagogical, and content decisions, and the implications of those decisions for student's conceptual learning.The research presented here reports on the instructional design, pedagogical enactment, and subsequent effects on student learning of a climate change professional development (PD) model in the United States. Using anthropological theories of conceptual travel, we traced salient ideas from the PD through instructional delivery and into the evidence of student reasoning. We sought to address the following research questions: 1) How did a middle school teacher integrate climate change concepts into her science curriculum following PD participation? and 2) How did climate change instruction influence student understanding of key climate change constructs?From observation of the classroom instruction, we determined that the teacher effectively integrated new climate change information into her pre-existing schema. Additionally, through retrospective analysis of the PD, we found the design of the PD foregrounded the causes, mechanisms and likely effects of anthropogenic climate change at the expense of mitigation and adaptation strategies, and this differentially shaped how climate change was taught in the teacher's classroom. Analysis of student reasoning evidence showed that students gained an increased understanding of the enhanced greenhouse effect and the implications of human activity on this enhanced effect at statistically significant levels and with moderate effect sizes. However, students demonstrated a limited, though non-significant gain on

Full Text Available Solar Energy has been acknowledged as a free and infinite source of energy. In Built Environment (BE, solar energy has been used since pre-historic time. Many improvements and technologies .have been developed with respect to their potential. As solar supplies free energy, the issues with regard to their development in the BE will be examined. The solar energy is used in building either in Passive Solar Design (PSD or Active Solar Design (ASD. Rapid development in BE has caused global warming effect where the heating and cooling of the building contribute to half the total energy consumption of the nation and the construction industry leading to CO2 emission level at 300 million tonnes. It is found that solar energy produces different energy performances which result from different building technique that affected the environment in various ways. Whether or not the energy performances depend on the materials used, the equipment installed in the building or the energy sources supplied to the building , the improvement and development of solar energy still continues and grows.

We have designed, fabricated, and tested a 110 GHz-500 kW long-pulse gyrotron. The gyrotron incorporates a quasi-optical mode converter which transforms the oscillation mode, TE 22,2 , into a Gaussian radiation beam. The adoption of a built-in mode converter enabled us to design the electron beam collector so as to be capable of tolerating a 2 MW heat load. Attention was also paid to designing the gyrotron cavity and output window so as to permit long-pulse operations. In an experiment, we observed a maximum output power of 550 kW and achieved 1.3 s operation at a power level of 410 kW. (author)

The purpose of this study was conducted to explore the phenomenon of communal space setting of Pontianak State Polytechnic students from 8 departments of study both indoor and outdoor spaces. The research method used is a rationalistic study. The planned activities to be undertaken include the determination of communal places (indoor and outdoor), sample determination, data collection with surveys and interviews, presenting data and analysis and drawing conclusions as a basis for designing communal space for Polnep students. The research were analyzed of building and space character, analysis of space organization and circulation, space requirement analysis, material and color analysis, site analysis, and analysis of inner space elements and outer space elements. From the results of this study, it can be concluded that Polnep campus environment requires the addition of public space for students in conducting formal activities outside lectures. Some activity which to do some student such as activity to waiting lecturer, do some coursework, discussion, relaxation, extracurricular activities, and other informal activities still require adequate space infrastructure and are equipped with street furnitures such as garden lights, benches, outer space markers and shade vegetation.

Full Text Available Fundación Zain is developing new built heritage assessment protocols. The goal is to objectivize and standardize the analysis and decision process that leads to determining the degree of protection of built heritage in the Basque Country. The ultimate step in this objectivization and standardization effort will be the development of an information and communication technology (ICT tool for the assessment of built heritage. This paper presents the ground work carried out to make this tool possible: the automatic, image-based delineation of stone masonry. This is a necessary first step in the development of the tool, as the built heritage that will be assessed consists of stone masonry construction, and many of the features analyzed can be characterized according to the geometry and arrangement of the stones. Much of the assessment is carried out through visual inspection. Thus, this process will be automated by applying image processing on digital images of the elements under inspection. The principal contribution of this paper is the automatic delineation the framework proposed. The other contribution is the performance evaluation of this delineation as the input to a classifier for a geometrically characterized feature of a built heritage object. The element chosen to perform this evaluation is the stone arrangement of masonry walls. The validity of the proposed framework is assessed on real images of masonry walls.

Beam director design report

International Nuclear Information System (INIS)

Younger, F.C.

1986-08-01

A design and fabrication effort for a beam director is documented. The conceptual design provides for the beam to pass first through a bending and focusing system (or ''achromat''), through a second achromat, through an air-to-vacuum interface (the ''beam window''), and finally through the vernier steering system. Following an initial concept study for a beam director, a prototype permanent magnet 30 0 beam-bending achromat and prototype vernier steering magnet were designed and built. In volume II, copies are included of the funding instruments, requests for quotations, purchase orders, a complete set of as-built drawings, magnetic measurement reports, the concept design report, and the final report on the design and fabrication project

Background: The motivation for this work is built upon the premise that there is a need for research-based materials for design-based science instruction. In this paper, a small portion of our work investigating the impact of a LEGOTM engineering unit on fourth grade students' preconceptions and understanding of animals is presented. Purpose: The driving questions for our work are: (1) What is the impact of an engineering-design-based curricular module on students' understanding of habitat and animal classification? (2) What are students' misconceptions regarding animal classification and habitat? Sample: The study was conducted in an inner-city K-8 school in the northeastern region of the United States. There were two fourth grade classrooms in the school. The first classroom included seven girls and nine boys, whereas the other classroom included eight girls and eight boys. All fourth grade students participated in the study. Design and methods: In answering the research questions mixed-method approaches are used. Data collection methods included pre- and post-tests, pre- and post-interviews, student journals, and classroom observations. Identical pre- and post-tests were administered to measure students' understanding of animals. They included four multiple-choice and six open-ended questions. Identical pre- and post-interviews were administered to explore students' in-depth understanding of animals. Results: Our results show that students significantly increased their performance after instruction on both the multiple-choice questions (t = -3.586, p = .001) and the open-ended questions (t = -5.04, p = .000). They performed better on the post interviews as well. Also, it is found that design-based instruction helped students comprehend core concepts of a life science subject, animals. Conclusions: Based on these results, the main argument of the study is that engineering design is a useful framework for teaching not only physical science-related subjects, but

The microbiome of the built environment (MoBE) is a relatively new area of study. While some knowledge has been gained regarding impacts of the MoBE on the human microbiome and disease vulnerability, there is little knowledge of the impacts of the MoBE on mental health. Depending on the specific microbial species involved, the transfer of microorganisms from the built environment to occupant's cutaneous or mucosal membranes has the potential to increase or disrupt immunoregulation and/or exaggerate or suppress inflammation. Preclinical evidence highlighting the influence of the microbiota on systemic inflammation supports the assertion that microorganisms, including those originating from the built environment, have the potential to either increase or decrease the risk of inflammation-induced psychiatric conditions and their symptom severity. With advanced understanding of both the ecology of the built environment, and its influence on the human microbiome, it may be possible to develop bioinformed strategies for management of the built environment to promote mental health. Here we present a brief summary of microbiome research in both areas and highlight two interdependencies including the following: (1) effects of the MoBE on the human microbiome and (2) potential opportunities for manipulation of the MoBE in order to improve mental health. In addition, we propose future research directions including strategies for assessment of changes in the microbiome of common areas of built environments shared by multiple human occupants, and associated cohort-level changes in the mental health of those who spend time in the buildings. Overall, our understanding of the fields of both the MoBE and influence of host-associated microorganisms on mental health are advancing at a rapid pace and, if linked, could offer considerable benefit to health and wellness.
