Solid catadioptric telephoto lens design with SMS method

Two new optical structures are designed using the Simultaneous Multiple Surfaces (SMS) method, comprised of 2 reflecting surfaces and 2 refracting surfaces, 800mm focal length, f/8 (aperture diameter 100 mm) and 1.180 diagonal field of view in the SWIR band. The lens surfaces are rotational symmetric and calculated to have good control of non-paraxial rays. We have achieved designs with excellent performance, and with total system length of less than 60 mm

M-Libraries: Information use on the move

When people talk about mobile libraries, they tend to mean a bus or truck that has been kitted out as a roving branch library. However with a growing number of people accessing the internet from their pocket PCs and mobile phones, libraries are investigating ways to deliver their services to mobile phones and other small-screen devices so their customers can access them any time anywhere. This can be as simple as sending text message alerts about reservations becoming available or overdue books, or as complex as the Athabasca University Library’s Digital Reading room, which allows readers to access full eBooks and journal articles through their library’s subscriptions on any mobile device. These services have collectively become known as ‘m-libraries’.The Arcadia Programme has been funded by a generous grant from the Arcadia Fund. http://www.arcadiafund.org.uk

Forecasting electricity consumption using SARIMA method in IBM SPSS software

Forecasting is a prediction of future values based on historical data. It can be conducted using various methods such as statistical methods or machine learning techniques. Electricity is a necessity of modern life. Hence, accurate forecasting of electricity demand is important. Overestimation will cause a waste of energy but underestimation leads to higher operation costs. Univesity Tun Hussein Onn Malaysia (UTHM) is a developing Malaysian technical university, therefore there is a need to forecast UTHM electricity consumption for future decisions on generating electric power, load switching, and infrastructure development. The monthly UTHM electricity consumption data exhibits seasonality-periodic fluctuations. Thus, the seasonal Autoregressive Integrated Moving Average (SARIMA) method was applied in IBM SPSS software to predict UTHM electricity consumption for 2019 via Box-Jenkins method and Expert Modeler. There were a total of 120 observations taken from January year 2009 to December year 2018 to build the models. The best model from both methods is SARIMA(0, 1, 1)(0, 1, 1)12. It was found that the result through the Box-Jenkins method is approximately the same with the result generated through Expert Modeler in SPSS with MAPE of 8.4%

The intention to use mobile digital library technology: A focus group study in the United Arab Emirates

IGI Global (“IGI”) granted Brunel University London the permission to archive this article in BURA (http://bura.brunel.ac.uk).This paper presents a qualitative study on student adoption of mobile library technology in a developing world context. The findings support the applicability of a number of existing constructs from the technology acceptance literature, such as perceived ease of use, social influence and trust. However, they also suggest the need to modify some adoption factors previously found in the literature to fit the specific context of mobile library adoption. Perceived value was found to be a more relevant overarching adoption factor than perceived usefulness for this context. Facilitating conditions were identified as important but these differed somewhat from those covered in earlier literature. The research also uncovered the importance of trialability for this type of application. The findings provide a basis for improving theory in the area of mobile library adoption and suggest a number of practical design recommendations to help designers of mobile library technology to create applications that meet user needs

The Open University Library in your pocket

The Open University library is working to support mobile learners through provision of mobile access to information management skills tutorials, the library website, and the library helpdesk. In 2007, we joined hands with the Athabasca University library team to develop the first mobile-friendly version of our library website. Since then, we have been actively researching and developing around other mobile library services, and more recently have consulted users to identify their requirements and what services they–d prefer to access through mobile phones. Recommendations from this user consultation (and from other sources, including regular users' feedback and by tracking user behavior through Google Analytics) include revamping the mobile version of the Library website to offer only the most used services on the home page, implementing SMS (Short Messaging Service) such as loan reminders or library reference service, and developing a consolidated search to offer results from various sources including the library catalogue and e-journals collection

Virtual Advice Services

The chapter looks at the issues involved with implementing and running a chat enquiry service, from choosing an appropriate product to staff training and publicity. The experiences of a number of UK Higher Education Institutions currently offering chat enquiry services are discussed at various stages. Aspects of more advanced use, such as web ‘co-browsing’ and virtual advice by appointment are also included. The chapter closes by considering what the future holds for virtual advice services and the potential impact of the growth in mobile technologies

Beyond “appropriate” technology. Mobilizing education for development

Having established that technology mediated instruction of some kind\ud has potential and a valuable role to play in education for on the move and remote\ud area learners the paper looks at practice as documented and suggests that social\ud and cultural barriers are a greater challenge than technological ones. It concludes\ud by suggesting that successful implementation may depend both on use of familiar\ud technology i.e. phones rather than internet, and establishing for users a social and\ud cultural validity for using that technology for the delivery of education

Hazard identification, risk assessment and risk control: a study at construction site

Occupational Safety and Health Act (OSHA) is an Act to make further provisions for securing the safety, health and welfare of persons at work, for protecting others against risks to safety or health in connection with the activities of persons at work, to establish the National Council for Occupational Safety and Health, and for matters connected therewith. This study focuses on infrastructure construction in Pagoh Education Hub. In present days, despite of knowledge in OSHA act, workers often proceed the work without considering any safety precaution or act at workplace as stated in OSHA Act. Due to ignorance of workers and employee on OSHA Act, workers are exposed to danger and hazard at their workplace causing them minor or worst fatal injury. The data collection was carried out through site investigation using Preliminary Hazard Analysis (PHA), HIRARC form and interview session with several workers in the constructio. The main objective of this study is to support the idea to coordinate and redefined the practice of occupational safety and health as workers discipline at their workplace based on existing potential hazard. This study was conducted to identify the hazard that occur at the workplace and analyse the safety precaution taken by the workers and employer to avoid accidents. As a result, this study listed several suggestions to improve the practice of occupational safety and health among workers in the workplace
