Fueled by ongoing digitization efforts, manufacturing is currently undergoing a transformational process towards interconnected machinery and workforce, which enables wide range of interactive monitoring controlling applications. Whereas existing user-centered work addressed remote from office workplaces, it remains unclear how workers experience adopt apps on mobile wearable devices. To close ...

This article presents a ubiquitous domain adaptation (UDA) and generalizability technique for vibration-based automated machine status monitoring at the edge. The method significantly reduces effects of signal noise artifacts device/usage-specific vibration signatures using basic time-frequency operations lightweight ensemble data-driven classifiers, allowing to be used reliable domain-invarian...

Recent technological advances in wireless communications, mobile computation, and sensor technologies have enabled the development of low-cost, miniature, lightweight, intelligent wireless sensor devices or “motes”. A collection of these devices can be placed strategically on the key positions of the human body and connected by means of a wireless network to form a Wireless Body Area Network (W...

In today's business environment in which coordination and adaptation with constant changes are the only ways of survival, real-time monitoring of activities and making the decisions accordingly are necessary. Since performance measurement cannot be managed independent of business processes, Business Activity Monitoring (BAM) systems should monitor performance metrics based on business processes...

In this paper, we present an overview of our research project with Gaia, a development infrastructure for ubiquitous applications. This infrastructure is based on three main elements: a component-based middleware operating system that provides a generic computational environment for ubiquitous computing, an application model that defines a standard mechanism to build ubiquitous applications, an...

The recent evolution of ubiquitous computing has brought with it a dramatic increase of event monitoring capabilities by wireless devices and sensors. Such systems require new, more sophisticated, event correlation over time and space. This new paradigm implies composition of events in heterogeneous network environments, where network and resource conditions vary. Event Correlation will be a mu...

Ubiquitous computing is not only applied to doing daily activities and integrated into everyday objects but for entertainment, and gaming as well. In this research, we explore the relevance of ubiquitous computing to entertainment systems using devices such as mobile devices. We introduce a service-oriented architecture for ubiquitous entertainment systems to establish collaborative relationshi...
