The Gaussian scale mixture model (GSM) is a simple yet powerful probabilistic generative model of natural image patches. In line with the well-established idea that sensory processing is adapted to the statistics of the natural environment, the GSM has also been considered a model of the early visual system, as a reasonable"first-order"approximation of the internal model that the primary visual...

Abstract. Artifact-centric business processes have recently emerged as an approach in which processes are centred around the evolution of business entities, called artifacts, giving equal importance to control-flow and data. The recent Guard-State-Milestone (GSM) framework provides means for specifying business artifacts lifecycles in a declarative manner, using constructs that match how execut...

GSM (Global System for Mobile) is the most widely-used cellular phone technology. Having begun mostly as a European standard, it has spread throughout the world to become ubiquitous. GSM was one of the first digital cellular systems, and as such, represented another level of magnitude in terms of complexity, with support for growth features such as GPRS (General Packet Radio Service), which pro...

1 work partially supported by CSISEI-CNR Abstract Mobility in cellular networks requires to manage handovers, which occur as users move from one cell to another. Their effects, which are easily overcome for speech, may seriously affect data transmissions. In this paper we report about tests for evaluating the quality of transmission for data applications on a GSM cellular network. Static tests,...

Case Management (CM) is a BPM technology for supporting flexible services orchestration. CM approaches like the OMG standard CMMN and one of its core influences GSM use Event-Condition-Action rules, which can be inconsistent due to cyclic interdependencies between the rules. Repairing an inconsistent case management schema is difficult. To avoid this problem, we provide a technique for automati...

We present the implementation of a communication architecture for accessing TCP/IP networks (mainly Internet) through GSM links. We exploit the existing and widely used TCP/IP communication architecture, but also take into account the specific features of wireless links and GSM networks. Our architecture is based in the indirect model of client/server interaction, where an intermediate element ...

The mobile telecommunication industry is becoming one of the most important industries in the world. In the spectrum of wireless communication technologies, digital cellular telecommunication using the Global System of Mobile Communication (GSM) standard has enjoyed the fastest growth rate. GSM has been adopted in more than one hundred countries, with spectacular national growths regardless of ...

In this paper we present a communication architecture for accessing TCP/IP networks (mainly Internet) through GSM. We exploit the existing and widely used TCP/IP communication architecture, but also consider the specific features of wireless links and GSM networks. Our proposal is based in the indirect model of client/server interaction, where an intermediate element acts as a bridge between GS...
