Effect of line of sight propagation on capacity of an indoor MIMO system

In this paper the performance of a multiple input multiple output (MIMO) wireless communication system operating in an indoor environment, featuring both line of sight (LOS) and non-line of sight (NLOS) signal propagation, is assessed. In the model the scattering objects are assumed to be uniformly distributed in an area surrounding the transmitting and receiving array antennas. Mutual coupling effects in the arrays are treated in an exact manner. However interactions with scattering objects are taken into account via a single bounce approach. Computer simulations are carried out for the system capacity for varying inter-element spacing in the receiving array for assumed values of LOS/NLOS power fraction and signal to noise ratio (SNR).

How do older people with sight loss manage their general health? A qualitative study

Purpose: Older people with sight loss experience a number of barriers to managing their health. The purpose of this qualitative study was to explore how older people with sight loss manage their general health and explore the techniques used and strategies employed for health management. Methods: Semi-structured face-to-face interviews were conducted with 30 participants. Interviews were audio-recorded, transcribed verbatim and analysed using thematic analysis. Results: Health management challenges experienced included: managing multiple health conditions; accessing information; engaging in health behaviours and maintaining wellbeing. Positive strategies included: joining support groups, clubs and societies; using low vision aids; seeking support from family and friends and accessing support through health and social care services. Conclusion: Healthcare professionals need to be more aware of the challenges faced by older people with sight loss. Improved promotion of group support and charity services which are best placed to share information, provide fora to learn about coping techniques and strategies, and give older people social support to prevent isolation is needed. Rehabilitation and support services and equipment can only be beneficial if patients know what is available and how to access them. Over-reliance on self-advocacy in current healthcare systems is not conducive to patient-centred care. Implications for Rehabilitation Sight loss in older people can impact on many factors including health management. This study identifies challenges to health management and highlights strategies used by older people with sight loss to manage their health. Access to support often relies on patients seeking information for themselves. However, self-advocacy is challenging due to information accessibility barriers. Informal groups and charities play an important role in educating patients about their condition and advising on available support to facilitate health management.

Hidden in plain sight:low-literacy adults in a developed country overcoming social and educational challenges through mobile learning support tools

Illiteracy is often associated with people in developing countries. However, an estimated 50 % of adults in a developed country such as Canada lack the literacy skills required to cope with the challenges of today's society; for them, tasks such as reading, understanding, basic arithmetic, and using everyday items are a challenge. Many community-based organizations offer resources and support for these adults, yet overall functional literacy rates are not improving. This is due to a wide range of factors, such as poor retention of adult learners in literacy programs, obstacles in transferring the acquired skills from the classroom to the real life, personal attitudes toward learning, and the stigma of functional illiteracy. In our research we examined the opportunities afforded by personal mobile devices in providing learning and functional support to low-literacy adults. We present the findings of an exploratory study aimed at investigating the reception and adoption of a technological solution for adult learners. ALEX© is a mobile application designed for use both in the classroom and in daily life in order to help low-literacy adults become increasingly literate and independent. Such a solution complements literacy programs by increasing users' motivation and interest in learning, and raising their confidence levels both in their education pursuits and in facing the challenges of their daily lives. We also reflect on the challenges we faced in designing and conducting our research with two user groups (adults enrolled in literacy classes and in an essential skills program) and contrast the educational impact and attitudes toward such technology between these. Our conclusions present the lessons learned from our evaluations and the impact of the studies' specific challenges on the outcome and uptake of such mobile assistive technologies in providing practical support to low-literacy adults in conjunction with literacy and essential skills training. © 2013 Her Majesty the Queen in Right of Canada.
