TL;DR: This paper proposes unsupervised learning methods for human activity recognition, with sensor data collected from smartphone sensors even when the number of activities is unknown, and believes that the results of the approach provide a way of automatically selecting an appropriate value of k at which the accuracy is maximized forActivity recognition, without the generation of training datasets by hand.

TL;DR: A context aware framework to send information from wearable sensors to healthcare service entities as a middleware to solve the interoperability problem between sensor makers and healthcare service providers is developed.

TL;DR: A UPnP AV architectural multimedia system with a home gateway powered by the OSGi platform, which gives interoperability among multimedia home devices in home network environment, and a powerful tool for multimedia content providers to provide smarter multimedia service for users in a home.

TL;DR: The proposed home server scheme is an integrated form of a home multimedia server, a home control server, and a home information server that has an interface between access networks and home networks, various kinds of wired and wireless home networks devices, and multimedia processing modules.

TL;DR: In this article, a system of delivery of a virtual machine using context information is described, which includes a context information manager that receives one or more user context information from a user terminal device, and a VM generator that generates a VM suitable for the user terminal devices in accordance with the one ore more received user context.
