There are very few, if any, published accounts of practical expe­ rience with Speaker Verification as a means to provide secure access to telematics services. Yet, there is no reason to expect that Speaker Verification is very different from speech recogni­ tion, for which many deployed services have shown the need for close and intensive on-line monitoring during the time when the service beco...

Many mobile computing applications can proot from process groups and reliable multicast communication to maintain replicated data, but most operating systems available today fail in providing the primitive operations needed by such applications. In this paper we describe a highly conngurable, Generic Multicast Transport Service (GTS), which supports the implementation of group-based application...

The importance of business related services has been growing consequently during the past years. Industrial Services constitute the greatest share of business related service with 30% of their intermediate output. But those kinds of services are facing tremendous challenges in terms of synchronizing their process with the manufacturing processes of their customers. The EU funded project InCoCo-...

This paper introduces a dynamic map for mobile robots that adapts continuously over time. It resolves the stabilityplasticity dilemma (the trade-off between adaptation to new patterns and preservation of old patterns) by representing the environment over multiple timescales simultaneously (5 in our experiments). A sample-based representation is proposed, where older memories fade at different r...

In the conventional IP network, equipment has been managed by periodical SNMP polling and periodical ping by a network management system (NMS), and traps have been used when abnormalities occur. But it is difficult to operate a service related to network state changes by such a management method because IP network services are best-effort services, so they may be affected by other multiplexed t...

The government has regulated the pattern of identification and registration motor vehicle ownership administration imposition taxes, including compulsory donations traffic accident funds through One Roof Motor Vehicle Administration System, abbreviated as SAMSAT. performance service operations at SAMSAT office in West Java Province not reached optimal stage. This is allegedly related to impleme...

This paper presents an improvedmodel for improving headway-based bus route service reliability at bus stops using real-time preventive operation control, taking into account dynamic interaction among random passenger demand, stochastic driving conditions of route segments, and vehicle load capacity constraint. In this model, the real-time information of passenger demand and vehicle operation is...

This paper presents a metamodel that addresses service system design and innovation by traversing and integrating three essential layers, service activities, service systems, and value constellations. The metamodel's approach to service systems as service-in-operation is an alternative to another currently used approach that views service systems as systems of economic exchange. The metamodel a...
