We introduce an approach that allows the use of mobile devices as an extension to an already existing HIS providing the full range of functions of the system. GSD has developed an extension to its product IS-H*MED (SAP R/3 based) using mobile devices, WirelessLAN and Web technology, which allows synchronised access to IS-H*MED functions and data likewise. The most important functions provided b...

The efficient support of multiple traffic classes with different quality of service requirements (end-to-end delay, jitter, loss) poses an extraordinary complexity in the design of third-generation mobile networks. This task becomes especially critical for the access network, where radio and transmission resources are usually scarce. In this paper we present a simulation model of the ATM-based ...

Our case-control studies were the first to report an association between the use of mobile or cordless phones and brain tumors; glioma and acoustic neuroma. Criticism of these results has been based partly on results from the Interphone studies conducted under the auspice of the International Agency for Research on Cancer (IARC). Here, we compare study design and epidemiological methods used in...

Micropayments provide companies and individual persons a way to obtain potentially a great deal of revenue for the digital content (such as music, games). At the moment lot of digital content is either not provided at all or is provided for free. The micropayment business has a great revenue potential in future. So far only few companies have managed to reach considerable success. Mobile test b...

The contribution of this paper, is the integration of network mobility (NEMO) and ad hoc networking (MANET) approaches in realized heterogeneous environment. The experimented prototype system applies existing Mobility support for IPv6 (MIPv6), NEMO, Ad hoc On-demand Distance Vector (AODV) routing protocol, and IEEE 802.11b Wireless LAN (WLAN) technologies to enable end-toend connectivity of a m...

This paper focuses on one of the most important aspects of user mobility in a ubiquitous mobile environment: application session hand-off management. Here we use the term Session Mobility to define the ability of handling application session hand-offs among mobile devices. The paper summarizes the current research in the field and addresses the important facets and the missing “ingredients” of ...

Ambient networks are envisioned to be a combination of diverse but complementary access technologies. Internetworking these types of networks will provide mobile users with ubiquitous connectivity across a wide range of networking environments. The composition of existing and emerging heterogeneous wired/wireless networks requires the design of intelligent networks components to enable mobile u...

Augmented Reality (AR), enhancing a user’s perception of the real world with computer generated entities, and mobile computing, allowing users to access and manipulate information anytime and independent of location, are two emerging user interface tech­ nologies that show great promise. The combination of both into a single system makes the power of computer enhanced interaction and communicat...

3G-WLAN interworking is an emerging technology for the convergence of heterogeneous wireless networks. Solutions to unified authentication using Universal Subscriber Identity Module (USIM) card are urgent demands for wireless network operators, wireless service providers, and mobile users. However, it is a challenging issue to achieve unified authentication based on current network infrastructu...

In this paper, we show two approaches for capturing nursing interactions in a hospital: 1) finding nursing intervals from mobile sensors with accelerometers and audio on nurses, and 2) recognizing nurses’ entrance to a patient’s room from in-room sensors of bed, loudness, and illuminance sensors. For 1), we firstly detect the nurses’ entrance to the patient’s room by walking detection from acce...
