Performance evaluation of different techniques to estimate subjective quality in live video streaming applications over LTE-Advance mobile networks

2018

Abstract Current mobile service providers are offering Gigabit Internet access over LTE-Advanced networks. Traditional services, such as live video streaming, over wired networks are feasible on these networks. However different aspects should be taken into account due to the fast changing network conditions as well as the constrained resources of the mobile phones, in order to provide a good subjective video quality in terms of Mean Opinion Score (MOS). Our goal is to estimate and predict this subjective metric without information or reference from the original video, known as Non Reference approach. This approach is important for the Service Provider from a practical point of view, becaus…

Can Digital Coaching Boost Your Performance? – A Qualitative Study among Physically Active People

2019

The use of sport and wellness technology devices among athletes is highly popular. At the same time the demand for easy to understand, clear, and personalized information is also growing. Instead of numbers, users need and want solutions. Digital coaching can offer solutions for this by providing valuable training data and offering guidance and instructions on how to improve the training. This exploratory study focuses on the experiences, needs, and wants regarding a digital coach application among physically active people, more precisely crosscountry skiers. We found that the digital coach was perceived to have motivational elements. It was also viewed having potential to increase the awar…

Semantic Web Services for Smart Devices in a “Global Understanding Environment”

2003

Various Web resources and services are usually assumed to be used and accessed by human users (current Web) or by software agents on behalf of human users (emerging Semantic Web). However industry emerges also a new group of “users”, which are smart industrial devices, robots or any other objects, which can be adapted to the (Semantic) Web environment. They would need special services for e.g. online condition monitoring, information provisioning, remote diagnostics, maintenance support, etc. The goal of this paper is to specify main requirements to Web services that automatically follow up and predict the performance and maintenance needs of field devices. Semantic Web enabled services for…

Semantic Web Services for Smart Devices Based on Mobile Agents

2005

Among traditional users of Web resources, industry has a growing set of smart industrial devices with embedded intelligence. Just like humans, they need online services (i.e., for condition monitoring, remote diagnostics, maintenance, etc.). In this paper, we present one possible implementation framework for such Web services. Such services should be Semantic Web enabled and form a Service Network based on internal and external agents’ platforms, which can host heterogeneous mobile agents and coordinate them to perform needed tasks. The concept of a “mobile service component†assumes not only exchanging queries and service responses, but also delivering and composition of a service pro…

Intentions to use mobile services: Antecedents and cross-service comparisons

2005

- This article develops and tests a model to explain consumers' intention to use mobile services. Through triangulating theories from the diverse fields of information systems research, uses and gratification research, and domestication research, the authors put forth an integrated model that explains intention to use mobile services. The model proposes four overall influences on usage intention: motivational influences, attitudinal influences, normative pressure, and perceived control. The authors study the type of interactivity and process characteristics associated with the service that moderate the effects on the relationship between the proposed antecedents and usage intention. The res…

Using Sport and Wellness Technology to Promote Physical Activity: An Intervention Study among Teenagers

2019

Life-long physical activity patterns are established during teenage years. Thus, promoting physical activity for teenagers is important. Sport and wellness technology shows promise for promoting physical activity. Yet, its research with teenage populations is sparse. This intervention study focused on whether using a sport and wellness technology application could affect the physical activity intention of teenagers, its antecedents, and the antecedents’ effects on intention by using the theory of planned behavior combined with the concept of self-efficacy as a theoretical framework. The results showed no statistically significant difference between the intervention and the control group in …

Service Provisioning and User Association for Heterogeneous Wireless Railway Networks

2017

In addition to comforting passengers' journey, the modern railway system is responsible to support a variety of on-board Internet services to meet the passenger's demands on seamless service provisioning. In order to provide wireless access to the train, one idea attracting increasing attention is to deploy a series of track-side access points (TAPs) with high-speed data rates along the rail lines dedicated to the broadband mobile service provisioning on board. Due to the heavy data traffic flushing into the base stations (BSs) of the cellular networks, TAPs act as a complement to the BSs in data delivery. In this paper, we focus on the TAP association problem for service provisioning in a …
