Combined effect of the horizontal components of earthquakes for moment resisting steel frames

The commonly used seismic design procedures to evaluate the maximum effect of both horizontal components of earthquakes, namely, the Square Root of the Sum of the Squares (SRSS) and the 30-percent (30%) combination rules, are re-evaluated. The maximum seismic responses of four three-dimensional moment resisting steel frames, in terms of the total base shear and the axial loads at interior, lateral and corner columns, are estimated as realistically as possible by simultaneously applying both horizontal components. Then, the abovementioned combination rules and others are evaluated. The numerical study indicates that both, the SRSS rule and the 30% combination method, may underestimate the combined effect. It is observed that the underestimation is more for the SRSS than for the 30% rule. In addition, the underestimation is more for inelastic analysis than for elastic analysis. The underestimation cannot be correlated with the height of the frames or the predominant period of the earthquakes. A basic probabilistic study is performed in order to estimate the accuracy of the 30% rule in the evaluation of the combined effect. Based on the results obtained in this study, it is concluded that the design requirements for the combined effect of the horizontal components, as outlined in some code-specified seismic design procedures, need to be modified. New combination ways are suggested.
Low-resistance self-aligned Ti-silicide technology for sub-quarter micron CMOS devices

A low-resistance self-aligned Ti-silicide process featuring selective silicon deposition and subsequent pre-amorphization (SEDAM) is proposed and characterized for sub-quarter micron CMOS devices. 0.15-/spl mu/m CMOS devices with low-resistance and uniform TiSi/sub 2/ on gate and source/drain regions were fabricated using the SEDAM process. Non-doped silicon films were selectively deposited on gate and source/drain regions to reduce suppression of silicidation due to heavily-doped As in the silicon. Silicidation was also enhanced by pre-amorphization, using ion-implantation, on the narrow gate and source/drain regions. Low-resistance and uniform TiSi/sub 2/ films were achieved on all narrow, long n/sup +/ and p/sup +/ poly-Si and diffusion layers of 0.15-/spl mu/m CMOS devices. TiSi/sub 2/ films with a sheet resistance of 5 to 7 /spl Omega//sq were stably and uniformly formed on 0.15-/spl mu/m-wide n/sup +/ and p/sup +/ poly-Si. No degradation in leakage characteristics was observed in pn-junctions with TiSi/sub 2/ films. It was confirmed that, using SEDAM, excellent device characteristics were achieved for 0.15-/spl mu/m NMOSFET's and PMOSFET's with self-aligned TiSi/sub 2/ films.

Results — One hundred and seventy-two (49.0%) of the students had a problematic CPU. Cronbach’s alpha and ICC were 0.8 and 0.91, respectively. The model had acceptable goodness of fit indices in confirmatory factor analysis. Conclusion — The Persian version of PCPU-Q had good psychometric properties and can be useful for screening of problematic CPU among Iranian youth.
Role of Dynamic Information in Supporting Changes in Travel Behavior

Travelers can often benefit from acquiring relevant information on their intended modes and routes. By providing pretrip and en route information, advanced traveler information systems present real opportunities for improving the travel experience of individuals and increasing efficiency of the transportation system. In this regard, it is important to understand how consumers acquire and respond to travel information. This study develops a conceptual framework identifying important factors influencing travelers’ information acquisition behavior and their response to dynamic information. The model is empirically tested with the use of a recent and comprehensive regional travel survey. A sample selection model is estimated to be consistent with the two-stage processing of travel information (i.e., acquisition and response). Results show that information acquisition and changes in travel plans are sensitive to different sets of factors. In the data set analyzed, normal travel time to work is found to be a critical factor in information acquisition, but has an insignificant association with the change of travel plans. Furthermore, travelers respond differently to various information technologies. In an examination of change behavior (including route change, mode change, and trip cancellation), Internet access had the strongest association with change. With examination of specific route change behavior, transportation information obtained through radio had the strongest association with change. The study generates useful implications on how to improve existing and future traveler information systems.
A Pilot Retrospective Study Validating Noncommunicable Disease Risk Assessment Score (AMNRAS)

Background: Globally Noncommunicable Diseases is lead causes of mortality. This calls for the need of sensitive and cost appropriate screening tools to identify asymptomatic healthy individuals with higher risk and/or subclinical NCD in the community. The study aims to generate pilot evidence based, validated, good quality, cost appropriate, and sustainable risk assessment score for NCD for developing countries like India. Methods: This descriptive retrospective study of diabetic camp data of 84 patients was conducted. A risk score having 10 questions and three measurements for NCDs appropriate for Indian communities was generated. It was compared to IDRS, FINDRISC, FRS, CBAC, and WHO/ISH prediction charts. Results: The study finally included 36 patients with NCD as case and 44 subjects without NCD as control. The means of weight, waist circumference, blood pressure, and blood sugar were significantly different among the two groups. AMNRAS of more than 14 was highly predictive for an individual to be at risk of NCD or sub clinical case of NCD requiring evaluation. The proposed cut-off of 8 for AMNRAS, the sensitivity and NPV was highest compared to other score, 88.9% and 84.6%, respectively. Score for the Area under curve was significantly higher for AMNRAS [0.83 (0.74 to 0.92)] compared to other scores. Conclusions: AMNRAS has higher performance parameters than the other five tested in the present study. Other scoring system performs only modestly in discrimination of NCD cases. The accuracy of AMNRAS for NCD risk will have to be determined in large size cohorts.
The Impact of CTS on Computer-Games Playing: A Study Among Malaysian University Students

—Carpal Tunnel Syndrome (CTS) is known to be one of the hand complications resulting from prolonged static posture and high muscle tension, particularly during computer-game playing. This study focuses on examining the impact of CTS during computer-game playing among university students in Malaysia. For the purposes of this study, students in the age range of 18-25 years and have experiencing hand discomforts, such as numbness, tingling, pain or burning sensations while playing computer games were approached. A Boston Carpal Tunnel Questionnaire (BCTQ) was administered and students reported on the frequency, the severity of CTS and experiences during computer-game playing. The commonest symptom was numbness. Most of the symptom cases were mild and half of the respondents also described having hand difficulty. This problem creates a great impact relating to their subsequent playing experiences. This study shows that, CTS among the students is in the mild category.
A Study of Solar Reflector Efficiency of Parabolic Dual Trough

Problem statement: The receiver of parabolic dual trough had been designed and built in order to increase efficiency of solar radiation accumulation by using iron-aluminum sheet as an intermediate in receiving heat and it is the study into how to benefit from solar radiation energy. This research proposed the principle of changing solar radiation to be heating energy by using aluminum sheet made into dual parabolic curve tilted with iron-aluminum sheet which was receiver of radiation reflection. Approach: This dual parabolic curve could be adjusted so that heat obtained from the solar radiation accumulation, which was the focus, could spread around iron-aluminum sheet. In testing of heating by solar energy, the unit would be tilted at 16° to the North-South in order to receive solar radiation and the unit was arranged horizontally. The test was classified into 4 conditions including (1) laying the unit horizontally and un-drive the motor, iron-aluminum sheet would be put in place unmoved in vertical line; (2) laying the unit horizontally and drive motor so that iron-aluminum sheet could be moved upwards and downwards along the vertical line; (3) laying the unit to be tilted at 16° with plane level and un-drive motor and (4) laying the unit to be tilted at 16° with the plane level and drive motor so that iron-aluminum sheet could be moved upwards and downwards along the vertical line. Results: It was found from the test of temperature of iron-aluminum sheet that on the first condition, the highest temperature of iron sheet was 75.2°C and the highest temperature of aluminum was 84.7 °C; on the second condition, the highest temperature of iron sheet was 90.6°C and the highest temperature of aluminum was 97.2°C; on the third condition, the highest temperature of iron sheet was 87.4°C and the highest temperature of aluminum was 93.4°C; on the fourth condition, the highest temperature of iron sheet was 94.5°C and the highest temperature of aluminum was 89.4°C. Therefore, the test of laying the unit to be tilted at 16° with the plane level and driving motor leaded to the high temperature since the perpendicular of light and the spreading of sunlight from dual parabolic curve could cover all area. Conclusion: These results indicate dual parabolic curve could be increased efficiency of solar radiation accumulation by using iron-aluminum sheet as an intermediate in receiving heat.
Application of the short‐open calibration technique to vector finite element method for analysis of microwave circuits

A novel numerical de‐embedding scheme called the short‐open calibration (SOC) technique, in conjunction with the vector finite element method (FEM), has been developed to characterize two‐port network of arbitrarily shaped, three‐dimensional discontinuities in microwave circuits. This SOC technique is effectively implemented into the FEM for boundary truncation of the unbounded circuit structures. In such a manner, fast convergence of iterative solver for large‐sparse linear matrix equations from FEM is achieved. The SOC technique is used to remove parasitic effects brought by the approximation of the impressed voltage source and also the problem of resulting consistency between the two‐ and three‐dimensional simulations. Scattering parameters of discontinuous sections are constructed from the definition of port voltages and currents. Numerical solutions are well compared with those published in the available literatures. It is demonstrated that the features of the SOC technique are advantageous when combined with FEM for electromagnetic problems. Copyright © 2002 John Wiley & Sons, Ltd.
We Innovate: The Role of Collaboration in Exploring New Technologies

Pre-service teachers faced an old problem with new possible solutions by working collaboratively to learn new technologies and changed the way they react to new tools. This approach required students to explore technologies independent of instructors—with peers in small groups. Instructors believe the learning activities implemented in this project to facilitate learning new technology are better aligned with professional development realities of their students’ future profession. The old problem with the “inability to keep up with all the new technologies” and the new teaching strategy of “collaborative learning communities” prompted the development of the Innovations Mini-Teach course project. Through focus groups, an end-of-semester course effectiveness survey, and analysis of students’ final products, this study showed that collaboration can be a superior method for helping pre-service students independently learn about the innovative technology tools that may be helpful to them as teachers, explore a professional development model that could support them in their future teaching careers, and most importantly see themselves as future innovators. Finally, students in focus groups indicated their class wiki, which archived each group’s consequential knowledge, would continue to support them to become teacher-leaders of technology integration.
Studying on temperature Cole-Cole diagrams by dielectric temperature spectrum

Polarization phenomena related to temperature are discussed by establishing a Temperature Cole-Cole diagram on the basis of the dielectric temperature spectrum. The Cole-Cole diagram is generally used for studying the dielectric polarization characteristic according to the variation of permittivity /spl epsi/' and dielectric loss /spl epsi/" with frequency at constant temperature. In this paper, the Cole-Cole equation has been varied starting from the microcosmic parameter describing dielectric polarization dependence on temperature, so that the Temperature Cole-Cole diagram can be obtained and used for studying polarization and loss phenomena on the basis of the dielectric temperature spectrum. The results of this research may provide new ideas for studying the mechanism of dielectric polarization and loss.
Unequal Partnerships in Higher Education: Pedagogic Innovations in an Electronics within Physics Degree Course

This cross-European research partnership reports on supporting pro-active learning and teaching. The two-part project firstly explored student beliefs about electronics within a physics degree and secondly, the use of peer assessment of a Mathematica notebook to develop understandings of standards and quality. Student beliefs were explored because of the negative perceptions tutors thought students brought to the Engineering course within the Physics degree. The results showed that tutors’ fears were unfounded and that the students were highly motivated. Secondly, through peer assessment of a notebook, students developed critical understandings of standards and quality. Generally, students valued the content support and appreciated both the work of their peer and how this helped their own understanding.
Strengthening work engagement through digital engagement, gamification and psychosocial safety climate in digital transformation

The problem faced in technological developments and during the pandemic is transforming employee habits from offline to online work engagement. This research aims to look at empirical evidence regarding the relationship between digital engagement, gamification, and psychosocial safety climate (PSC) on work engagement. This study employs a quantitative approach with structural equation modelling, analyzing a series of exploratory and confirmatory factors to determine the relationship between variables. This study uses primary data through a questionnaire of as many as 164 respondents with a purposive sampling technique. This study proves that digital engagement and gamification variables on PSC and work engagement have a significant positive effect. Aspects of digital transformation through digital engagement and gamification influence PSC to increase work engagement. The relationship between gamification channelled through PSC can also mediate and prove a positive influence in strengthening work engagement.
The Research of Three Significant Changes Resulted from Industrialization in the Development of Architecture

Architecture has changed dramatically along with the development of industrialization. In contrast to some of the more traditional methods of the construction industry organized predominantly along craft lines, architecture can now be the industrial product of components made in a factory [1]. It is the big change in the process of designing, manufacturing and constructing. The three changes make architecture a kind of industrial product, and not only an art work or something else. What details about these changes involved, why these changes exist and how these changes influence architecture are all main things to study. Through analyzing some particular buildings, these problems were made clear, and we found what is good or bad in these changes for architecture. On the basis of the research, we could get a good answer to the direction of the development of architecture in form, design, manufacture style and constructing process.

A self-starting procedure for monitoring process quality in multistage manufacturing systems

Manufacturing systems typically contain processing and assembly stages whose output quality is significantly affected by the output quality of preceding stages. The deficiencies of using standard statistical process-monitoring procedures in such systems have been highlighted in the literature. This article proposes a procedure to monitor process and product quality in multistage systems. By accounting for the quality of the input to each stage, the procedure not only detects the presence of out-of-control conditions but also helps to identify the stages responsible for such departures. We extend previous research to the common case where the process parameters are unknown. An extensive performance study shows that the procedure is effective in detecting out-of-control conditions and that it convincingly outperforms existing methods. We illustrate the use of the procedure using production line data from a major electronics manufacturer. †Deceased
Everyday data cultures and USB portable flash drives

In this article, we present a deeper understanding of everyday data cultures in regards to personal information management practices. We draw on a study involving 14 in-depth interviews with users of portable hard drives and USB portable flash drives in Melbourne, Australia, to examine participants’ reflections on their management of personal information on USB portable devices. In examining participant use of these devices, we consider how they kept (stored) and organized (arranged) information on these devices. We also examined device and data sharing. We conclude by thinking about their increased use within cross-tool information management, including the nexus of portable hard drive/USB use and cloud storage. The argument of this article is that portable hard drives and USBs, due to their miniaturization, ease of portability, affordability and storage capacity, add considerable complexity to established understandings of personal information management practices.
Low power, tunable active inductor and its applications to monolithic VCO and BPF

A novel tunable active inductor for low power operation is presented. The DC power consumption of the proposed scheme is about 1/3 of conventional one with wider range of tunability and higher Q. The new bias scheme using the parallel and the series bias resistors reduces the number of bias pins and stabilizes the bias, effectively. This novel low power tunable active inductor is applied to wideband (35% tuning ratio) monolithic VCO and wide tunable (14% tuning ratio) monolithic BPF.
A physically-based model of the effective mobility in heavily-doped n-MOSFETs

We present a new analytical mobility model for channel electrons in heavily-doped MOSFETs biased from weak to strong inversion suitable for implementation in device simulation codes. The model accounts for the two-dimensionality of the electron gas and for the effect of charge trapping on the measurements and has been validated by comparing the theoretical curves with an extensive set of mobility measurements performed on devices with channel doping ranging from 3.8/spl times/10/sup 17/ to 1.25/spl times/10/sup 18/ cm/sup -3/ over a wide bias and temperature range (141-400 K).
