单片机制作语音录放电路

此论文所提出用单片机和ISD1420语音芯片实现的录放功能,其基本原理是将语音系统进行录音和放音。其中关键的技术在于:控制录音主要有两个数据:录音的开始地址和录音的时间。控制着两个数据就能在录音时实现将语音存入不同的地址中。注意,REC信号将被延迟50ms,以防止开关抖动引起重复触发,从而就能确保语音回放的可靠性质量。

The effects of project uncertainty and risk management on IS development project performance: A vendor perspective

The structural contingency perspective has been widely used in information systems development (ISD) project risk management research. This paper develops an integrative model to explore the moderating effects of uncertainty on the relationship between risk management and IS development project performance from a vendor perspective, rather than the client perspective that is mainly employed in the literature. A survey-based research design is used to collect data to test the proposed model. The results reveal that project uncertainty can moderate the effects of project planning and control on process performance and the effects of user participation on product performance. More specifically, the results indicate that project planning and control makes a greater contribution to process performance when there is a low level of inherent uncertainty and that user participation makes a greater contribution to product performance when there is a high level of inherent uncertainty. The results of this study contribute to a more acute understanding of the contingency approach to ISD project risk management.

The impact of transactive memory systems on IS development teams' coordination,communication, and performance

The high complexity nature of current contemporary software makes team a popular work style in information system development (ISD) projects. ISD is a knowledge intensive process which requires members to exchange and coordinate knowledge resources effectively. However, it is reported that ISD projects often failed because of coordination breakdown and insufficient knowledge exchange resulting from ineffective communication among team members. This highlights the importance of understanding how to enhance those knowledge-oriented teamwork activities. Drawing on this issue, this study aims at exploring the critical role of transactive memory system (TMS) on teamwork processes and performance. Data collected from 236 IS personnel confirmed our hypotheses that having a mature TMS can effectively enhance performance directly, and indirectly through improving communication and coordination process. Lastly, discussions of the results and implications toward practitioners and academia are provided.     

Comparison and evaluation of analytical models for the design of geosynthetic-reinforced and pile-supported embankments

Geosynthetic-reinforced and pile-supported (GRPS) embankments are becoming more and more popular as this technique showed good performances in practice. Various design methods were introduced to analyze GRPS embankments. However, the applicability of these design methods was not always fully validated. This paper focuses on the review of projects containing field observations of GRPS embankments. The comparison results showed that the assumptions related to the subsoil support, geosynthetic, arching shape, and its evolution are not consistent in the analytical methods. Comparison results with twenty-five full-scale cases and six series of experiments emphasize that these available design methods produce significantly different results in predicting loads transfer mechanism. The analytical models predict arching for cohesionless fill better that for cohesive fill soils. Besides, the analytical methods which consider subsoil support such as the CUR226 and EBGEO methods give results that are in a better agreement with experimental data as compared to other methods which do not consider the subsoil support. The CUR226 (2016) analytical model seems to be able to give the best performance with measured data when compared to other design methods. Finally, the results pointed out that the limit equilibrium model is adequate and has good performance.

Flexural behaviour of a half-decked bulb tee pre-stressed concrete girder: full-scale test and nonlinear finite element analysis

A half-deck bulb tee (HBT) girder, which is an unusual concept for pre-stressed concrete girders, was developed and tested for a long span application. The purpose of the test was to simplify the construction process and increase structural performance by optimising the cross sections and improving the efficiency of the tendon profile. In this study, a full-scale HBT girder, with a length of 60 m and depth of 2.3 m, which includes the .1 m depth of the half-deck, was fabricated and tested to analyse its structural performance. The data observed from the flexural loading tests were evaluated by comparing with the results of finite element analysis (FEA). The tested HBT girder specimen was expected to be sufficiently safe for actual bridge design because it satisfied construction code requirements. The initial cracking load observed during the experiment (1400 kN) was accurately predicted by FEA (1420 kN) and theory (1301 kN). Therefore, the developed HBT girder has sufficient and predictable flexural strength.

An instructional design for building energy simulation e-learning: an interdisciplinary approach

This article describes the development of a new instructional design (ISD) to promote building energy simulation (BES) education. The study is based upon education fundamentals combined with computer-based learning and hypermedia to enable the development of a BES-based distance learning system. Some cognitive tools are established such as: (i) an interdisciplinary knowledge tree of BES that can be used by professionals with different backgrounds; (ii) a hypermedia navigational aid to understand the simulation software, called the BES tool graphic organizer; (iii) a concept map with an overview of building energy performance and (iv) a cooperative problem-based learning (CPBL) environment. Furthermore, the paper also brings an analysis of the students’ comprehension – from a course applied across Brazil – by means of concept network graphs from text mining provided by the CPBL environment, showing a significant potential to develop interdisciplinary e-learning related to building energy efficiency.
