Mobile application development in AfricaRugunda, Solomon Mugume 21 February 2011 (has links)
This work takes a look at how some of the challenges facing the African Continent can be tackled by the use of Mobile Phone Applications. Mobile phone penetration in Africa is very high, as indicated by statistics from South Africa in 2009 which showed that 70% of all South Africans owned a cell-phone. As such, the mobile phone is the ideal infrastructure platform to introduce technology applications that can be easily accessed by the general public. The paper briefly discusses the current state of mobile applications on the continent including some key applications presently deployed and how they are being used to meet some major social challenges faced. The work then proposes the creation of the Mobile Doctor Application, a tool that gives simple solutions to end-users in response to their health related text message queries. The key stakeholders for this application and their respective roles are then discussed. The paper then details the requirements for the application, separates them logically and represents them graphically for a clear understanding. Also put forth are two possible different sets of architecture for this application, one fully manual and the other using different sets of technologies. Finally, each architecture is evaluated using compliance metrics and the ATAM Quality Attribute Tree / text

A Driver, Vehicle and Road Safety System Using SmartphonesGozick, Brandon 05 1900 (has links)
As vehicle manufacturers continue to increase their emphasis on safety with advanced driver assistance systems (ADAS), I propose a ubiquitous device that is able to analyze and advise on safety conditions. Mobile smartphones are increasing in popularity among younger generations with an estimated 64% of 25-34 year olds already using one in their daily lives. with over 10 million car accidents reported in the United States each year, car manufacturers have shifted their focus of a passive approach (airbags) to more active by adding features associated with ADAS (lane departure warnings). However, vehicles manufactured with these sensors are not economically priced while older vehicles might only have passive safety features. Given its accessibility and portability, I target a mobile smartphone as a device to compliment ADAS that can bring a driver assist to any vehicle without regards for any on-vehicle communication system requirements. I use the 3-axis accelerometer of multiple Android based smartphone to record and analyze various safety factors which can influence a driver while operating a vehicle. These influences with respect to the driver, vehicle and road are lane change maneuvers, vehicular comfort and road conditions. Each factor could potentially be hazardous to the health of the driver, neighboring public, and automobile and is therefore analyzed thoroughly achieving 85.60% and 89.89% classification accuracy for identifying road anomalies and lane changes, respectively. Effective use of this data can educate a potentially dangerous driver on how to operate a vehicle safely and efficiently. with real time analysis and auditory alerts of these factors, I hope to increase a driver's overall awareness to maximize safety.

In vitro effect of 900 MHz GSM radiation on mitochondrial membrane potential and motility of human spermatozoaFalzone,N, Huyser, C, le Roux Fourie, F, Toivo, T, Leszczynskid, D, Franken, DR January 2008 (has links)
Ejaculated, density purified, human spermatozoa were exposed to 900 MHz GSM mobile phone radiation at two specific absorption rate levels (SAR 2.0 and 5.7 W/kg) and examined
at various time points post exposure. Change in sperm mitochondrial membrane potential was analyzed using flow cytometry. Sperm motility was determined by computer assisted
sperm analysis (CASA). There was no effect of 900MHz GSM radiation on mitochondrial membrane potential. This was also the case for all kinematic parameters assessed at SAR of
2.0 W/kg. However, two kinematic parameters (VSL and BCF) were statistically significantly
altered after the exposure at SAR 5.7 W/kg. Effects seen cannot be ascribed to heating, as the temperature did not increase by more than 0.3ºC. A thorough investigation at lower SAR
levels is required to determine the extent of the influence of RF-EMF on human sperm motility.

InVitro effect of pulsed 900MHz GSMradiation on mitochondrial membrane potential and motility of human spermatozoaFalzone, N, Huyser, NC, Fourie, F, Toivo, T, Leszczynski, D, Franken, D January 2007 (has links)
Abstract
Ejaculated, density purified, human spermatozoa were exposed to pulsed 900 MHz GSM mobile
phone radiation at two specific absorption rate levels (SAR 2.0 and 5.7 W/kg) and compared with
controls over time. Change in sperm mitochondrial membrane potential was analysed using flow
cytometry. Sperm motility was determined by computer assisted sperm analysis (CASA). There was
no effect of pulsed 900 MHz GSM radiation on mitochondrial membrane potential. This was also the
case for all kinematic parameters assessed at a SAR of 2.0 W/kg. However, over time, the two
kinematic parameters straight line velocity (VSL) and beat-cross frequency (BCF) were significantly
impaired (P<0.05) after the exposure at SAR 5.7 W/kg and no exposure by time interaction was
present. This result should not be ascribed to thermal effects, due to the cooling methods
employed in the RF chamber and temperature control within the incubator.

Quantifying Human Movement Patterns for Public HealthWesolowski, Amy 01 May 2014 (has links)
Human travel affects important processes in public health and infectious disease dynamics. Refined spatial and temporal data are needed to accurately model how the dynamics of human travel contribute to epidemiological patterns of disease as well as access to healthcare resources. Here, I address a number of key issues related to modeling human mobility patterns and applications for understanding the spatial spread of infectious diseases and geographic access to public health resources. Using large sources of behavioral data anonymously collected from mobile phones within two African countries, I first analyze the utility of these data to quantify human mobility patterns as well as the usefulness of common modeling frameworks. Then I compare these data to two more common sources of human travel data: the national census and a comprehensive travel survey. Next, I use these data to assess the impact of human travel on the movement of malaria parasites. The final component of my thesis focuses on the utility of this data source to generally understand the role of geographic isolation on travel patterns to better understand the disparity between areas with various levels of access to public resources and the uptake of preventative healthcare such as immunizations and antenatal care.

The Smart Phone as a MouseQin, Yinghao January 2006 (has links)
With the development of hardware, mobile phone has become a feature-rich handheld device. Built-in camera and Bluetooth technology are supported in most current mobile phones. A real-time image processing experiment was conducted with a SonyEricsson P910i smartphone and a desktop computer. This thesis describes the design and implementation of a system which uses a mobile phone as a PC mouse. The movement of the mobile phone can be detected by analyzing the images captured by the onboard camera and the mouse cursor in the PC can be controlled by the movement of the phone.

MindMeLilja, Dan, Mattsson, Per January 2009 (has links)
<p>MindMe is an aid for people with cognitive memory impairments. The aid is completely new and has been</p><p>developed within this bachelor thesis, no product of this nature could be found on the market before. The</p><p>idea came from Niclas Jarhäll, CEO of Mutual Benefits. Mutual Benefits were also partners in the project.</p><p>The project was carried out by us in cooperation with Bachelor of Science in Innovation Engineering</p><p>students Malin Albertsson and Victoria Hedman at Halmstad university. The aid consists of a mobile phone</p><p>and a number of tags. The goal was for the mobile phone and tag to set of their alarms when they get a</p><p>certain distance apart.</p><p>It is the technical part of the project that will be discussed in this paper and it was divided in two parts,</p><p>prototype development and software for the mobile phone.</p><p>The project resulted in a prototype and an application for the mobile phone. The prototype and mobile phone</p><p>set of their alarms when they come to far apart. The user has the option to change settings in the mobile</p><p>phone application that affects both phone and tag and to add/remove tags. Both application and tag meet the</p><p>requirements set in the technical specification.</p>
