Design of LabVIEW® - based software for the control of sequential injection analysis instrumentation for the determination of morphine.

LabVIEW^®-based software for the automation of a sequential injection analysis instrument for the determination of morphine is presented. Detection was based on its chemiluminescence reaction with acidic potassium permanganate in the presence of sodium polyphosphate. The calibration function approximated linearity (range 5 × 10 ^-10 to 5 × 10 ^-6M) with a line of best fit of y = 1.05 x + 8.9164 (R² = 0.9959), where y is the log₁₀ signal (mV) and x is the log₁₀ morphine concentration (M). Precision, as measured by relative standard deviation, was 0.7% for five replicate analyses of morphine standard (5 × 10^-8_M). The limit of detection (3 σ) was determined as 5 × 10^-11 M morphine.

The market for software in the U.S.

The US market for software is investigated for the period 1964 to 2000, exploring the impact of price and non-price variables on software demand. and the impact of R&D and productivity on software supply. Software sales are positively associated with advertising, they are negatively affected by a rising consumer credit to GDP ratio. and are highly responsive to disposable income. Supply has been driven by productivity improvements.

Agile approaches to software maintenance : an exploratory study of practitioner views

Whilst there has been some research into the application of agile approaches to the world of software maintenance, in this paper it is argued that there has not been a coherent investiga-tion that focuses on the collection and analysis of the views and perceptions of agile software maintenance approaches held by experienced software maintenance professionals. In this paper, we report such an exploratory investigation, which has seeded the development of a simple framework for classifying collected views and perceptions. Specifically, a matrix framework has been introduced, to facilitate comparison of the levels of understanding of the issues affecting an agile adoption decision, and the extent to which an agile approach has been implemented. Examples of organizations operating in all four cells of this matrix have been presented. r />

Piloting social networking and Web 2.0 software at Deakin University

Deakin University piloted social networking software in order to complement and add a new dimension to its online learning and teaching efforts. In the first semester of 2007 eight teaching academics adopted three software applications. Six were used with students for learning while the other two were used by staff for professional development and research. This paper reports on the first attempt at providing institutional support for Web 2.0 and what was learned through the experience of these eight teaching academics which is essential to the ongoing development and decisions related to the future take up of these software applications.r />

Using social software to support the teaching of IT professional practice

Social software has been used to support problem-based learning activities in a wholly online information technology (IT) professional practice course at Deakin University since 2006. When the course was first delivered, the authentic learning environment was a website, with an intranet and team forums created in Drupal, the open source content management system (CMS). Although this environment was suitable, feedback from students and teaching staff highlighted areas where improvements could be made. In the second year of the course, Joomla!, the open source CMS, in combination with Simple Machines Forum (SMF), the open source online discussion community software, was used to provide the website, as well as the intranet and team forums respectively. Feedback in 2007 was more positive, suggesting that the Joomla!-SMF social software combination and the features implemented, improved the learning and teaching experience in comparison to the 2006 version of the course.r />

Building surfaces and their effect on the urban thermal environment

Use of high reflectance surfaces reduces the amount of solar radiation absorbed through building envelopes and urban structures and thus keeping their surfaces cooler. The cooling energy savings by using high reflectance surfaces have been well documented. Higher surface temperatures add to increasing the ambient temperature as convection intensity is higher. Such temperature increase has significant impacts on the air conditioning energy utilization in hot climates. This study makes use of numerical simulations to analyze the effect of commonly used building materials on the air temperature. A part of the existing CBD (Central Business District) area of Singapore was selected for the study. A series of Computational Fluid Dynamics (CFD) simulations have been carried out using the software CFX-5.6. It was found that at low wind speeds, the effect of materials on the air temperature was significant and the temperature at the middle of a narrow canyon increased up to 2.5[degrees]C with the facade material having lower reflectance. r />

A university-wide ePortfolio initiative at Federation University Australia: software analysis, test-to-production, and evaluation phases

This paper describes an ePortfolio implementation strategy at Federation University Australia, Victoria (formerly the University of Ballarat). The authors combined a personal and practical viewpoint to elicit pitfalls, challenges, and recommendations for improvement. The paper is divided into three main areas in order to outline the experiments that occurred. The first section provides a standard literature review around ePortfolio adoption as well as a research-based analysis of available ePortfolio software at Australian universities. The second part depicts the University’s ePortfolio implementation strategy that focused on “test-to-production” and technology dissemination phases. This section is based on the authors’ personal viewpoint of ePortfolio adoption at a university where a “top-down management decision making model” (Slade, Murfin, & Readman, 2013, p. 178) was used. Third, the evaluation strategy is reported, which was based on similar research conducted at Australian universities (Hallam & Creagh, 2010; Hallam, Harper, Hauville, Creagh, & McAllister, 2009). This part is offered as a modest-scoped, mixed methods evaluation process. The paper extends on ePortfolio implementation strategies (Bell & White, 2013; Coffey & Ashford-Rowe, 2014; Jarrott & Gambrel, 2011; Lambert & Corrin, 2007; Ring & Ramirez, 2012; Slade et al., 2013) and software analysis (ACODE, 2011; Slade et al., 2013). Recommendations are made for the careful integration of pre- and post-rollout of ePortfolio programs with face-to-face ePortfolio tutor support, offering online resources and alternative portfolio-making options for students with poor broadband access.

Managing trade-offs in adaptable software architectures

Making trade-offs in architecture is a fundamental activity in software design. As software is required to operate continuously in changing and uncertain environments, adaptability needs to be considered as a key issue, along with other more traditional software qualities. In this chapter, we introduce the concept of managing trade-offs in adaptable software architectures, discussing adaptability during the design of the software and as it runs. We outline important current approaches, challenges, and opportunities in managing these trade-offs.
