Digital systems have changed our world and will continue to change it. Supportive government policy, a strong research base and history of industrial success place the benefits of an emerging digital society. Protecting benefits and minimizing risks requires reliable and robust cyber security, backed by a robust research and translation system. Trust is essential for growth and maintenance of participation in the digital community. Organizations gain trust by acting in a trustworthy way leading to building reliable and secure systems, treating people, their privacy and their data with respect, and providing reliable and understandable information to help people understand how safe they are. Research and revolution in industry and academia will continue to make important contributions to create flexible and reliable digital environment.

This research is interested in the user ratings of Apps on Apple Stores. The purpose of this research is to have a better understanding of some characteristics of the good Apps on Apple Store so Apps makers can potentially focus on these traits to maximize their profit. The data for this research is collected from kaggle.com, and originally collected from iTunes Search API, according to the abstract of the data. Four different attributes contribute directly toward an App’s user rating: rating_count_tot, rating_count_ver, user_rating and user_rating_ver. The relationship between Apps receiving higher ratings and Apps receiving lower ratings is analyzed using Exploratory Data Analysis and Data Science technique “clustering” on their numerical attributes. Apps, which are represented as a data point, with similar characteristics in rating are classified as belonging to the same cluster, while common characteristics of all Apps in the same clusters are the determining traits of Apps for that cluster. Both techniques are achieved using Google Colab and libraries including pandas, numpy, seaborn, and matplotlib. The data reveals direct correlation from number of devices supported and languages supported to user rating and inverse correlation from size and price of the App to user rating. In conclusion, free small Apps that many different types of users are able to use are generally well rated by most users, according to the data. 展开更多

The public has access to a range of mobile applications(apps)for disasters.However,there has been limited academic research conducted on disaster apps and how the public perceives their usability.This study explores end-users'perceptions of the usability of disaster apps.It proposes a conceptual framework based on insights gathered from thematically analyzing online reviews.The study identifies new usability concerns particular to disaster apps'use:(1)content relevance depends on the app's purpose and the proximate significance of the information to the hazard event's time and location;(2)app dependability affects users'perceptions of usability due to the lifesafety association of disaster apps;(3)users perceive advertisements to contribute to their cognitive load;(4)users expect apps to work efficiently without unnecessary consumption of critical phone resources;(5)appropriate audio interface can improve usability,as sounds can boost an app's alerting aspect;and,finally(6)in-app browsing may potentially enhance users'impression of the structure of a disaster app.As a result,this study argues for focussed research and development on public-facing disaster apps.Future research should consider the conceptual framework and concerns presented in this study when building design guidelines and theories for disaster apps. 展开更多

This study aims to explore the Sultan Qaboos University undergraduate students’ perceptions and attitudes towards using m-Health app and its impact on improving their sports and health habits. Triangulation was used by applying a questionnaire and focus groups interviews to answer the research questions. The survey sample was (20) male and female students from four science and humanities colleges. Both quantitative and qualitative findings unequivocally reveal the students’ positive perceptions and attitudes toward the use of the mobile health app. No statistically significant differences were found between the responses of either males or females, or the science and humanitarian colleges of the sample students. In light of these findings, the study set forth its conclusions and recommendations. 展开更多

Hydroponic System is a system in which farmers cultivate different plants without utilizing the soil. The authors have proposed IoT system that monitors and controls all parameters of hydroponic system like water level, pH, humidity and temperature through mobile application. In proposed system, the authors have used an ESP32 micro-controller that is controlled pump. The pump will draw water from a reservoir which is connected to a regular water line. If the water level of the reservoir falls down to a certain level, the system will send an SMS to the Farmer. The farmer can control the water line and make the reservoir full by mobile application. An LDR and DHT11 humidity sensor is used to control the light and temperature of the farm. In system, we also used pH sensor where pH sensor is a scientific instrument that measures the hydrogen-ion activity in water-based solutions and indicating its acidity or alkalinity expressed as pH. 展开更多

Mobile news apps have emerged as a significant means for learning about latest news and trends. However, in light of numerous news apps and information overload, motivating users to adopt one app is a major concern for both the industry and academia. Therefore, considering the attributes of mobile news and the debate on switching costs in the Internet context, based on the expectation-confirmation model (ECM), this study suggests that switching costs still exist and have a significant moderating effect on user satisfaction and continuous usage of mobile news apps. Furthermore, the different influences of information quality, system quality and service quality on continuance intention, user satisfaction and switching costs are discussed, showing that quality of information has a significant impact on users’ continuous usage of mobile news apps through increasing perceived usefulness, whereas personalized service quality have stronger effects through increasing user satisfaction and switching costs. 展开更多

Leaving incontinence events unmanaged will make a negative influence on the aged and the patient both mentally and physically. This paper presents a design and implementation of a real time wireless monitor system for urinary incontinence, which has been applied in two nursing homes in Beijing and Shanghai. We collect real time moisture information by using non-contact humidity sensor designed and manufactured by us. When urinary incontinence, the sensor will send alert to mobile device via Bluetooth. If got the alert, the mobile device will send the alert to relatives of the aged or disabled people and cloud computing platform, through which we can make this information managed and displayed and the paramedic can be informed about the alarm. This paper gives a brief introduction to the framework of this system, the design of the non-contact sensor, the transmission of wireless data and the results of tests. 展开更多

Smart phones with unlimited applications are considered essential for modern day lifestyle, hence the number of cell phone users has sky rocketed in this decade. The high percentage of children and teenagers carrying cell phones has caused controversy on how justified having a minor carrying a communication device is. There is no doubt about the fact that parents have to be able to contact their children, however, a child with a phone and poor judgment will most probably be vulnerable to the outer world with all its’ threats and abuses. Furthermore, we have the serious health issues related to wireless devices effects on people, under those circumstances multiple solutions have been presented for a safe secure method for parents to track their children without the need of cell phones. The proposed alternatives included phones with limited privileges for children;these phones are restricted to the ability of calling specific people only and have already installed applications for tracking location. Our proposed system “kids’ tracker” includes a wearable device for the child and an Android application on the parents’ smart phone. Kids’ tracker has shown a very decent performance with many unique features compared to other existing solutions. 展开更多
