    Business Process Compliance via Security Validation as a Service

    Modern enterprise systems are often process based, i.e., they allow for the direct execution of business processes that are specified in a high-level language such as BPMN. In this paper, the authors present a service, called Security Validation as a Service (SVaaS) for validating the compliance of the business processes...

    Designing Business Processes with a Recommendation-Based Editor

    Knowledge of modeling language syntax is usually not sufficient for building \"Good\" process models. Profound modeling experience is required to apply a modeling language in practice. The productivity of users without any modeling experience is low and thus the quality of the modeling result may be unsatisfying if respective modeling...

    Comparative Study of VoIP Over WiMax and WiFi

    Recently wireless technology has grown immensely in popularity and usage becoming a medium of choice for networks. The wireless communication revolution is bringing fundamental changes to data networking, telecommunication, and is making integrated networks a reality. By freeing the user from the cord, personal communications networks, wireless LAN's, mobile radio...

    Whether Fiscal Stance Or Monetary Policy Is Effective For Economic Growth In Case Of South Asian Countries?

    Monetary policy and fiscal policy are sister strategies that can be used alone and in combination to direct the economic goals. In the literature relative efficacy of fiscal and monetary policy has been studied extensively. Friedman and Meiselman (1963), Ansari (1996), Reynolds (2000, 2001), Chari, et al. (1991, 1998), Schmitt...

    Fast Clustering of Self-Similar Network Traffic Using Wavelet

    In this paper the authors have given the proposed approximation methods for similarity search in large temporal databases using wavelet transformation based featured signals and time warping distance algorithm. The main goal is to propose efficient methods to speed up the mining of matched sequences especially when the sequences are...

    A Logical Temporal Relational Data Model

    Time is one of the most difficult aspects to handle in real world applications such as database systems. Relational database management systems proposed by Codd offer very little built-in query language support for temporal data management. The model itself incorporates neither the concept of time nor any theory of temporal...

    A Self-Adaptive Extensible Embedded Processor

    Extensible embedded processors allow the designer to adapt the instruction set to a certain application profile. It is either done during design time or at run time. In the latter case it is fixed when which part of the instruction set is used. The processor is then configured according to...

    A Service Oriented Framework for Mobile Business Virtual Communities

    The rise of the availability of mobile devices in the personal and professional domains leads to an increased need of middleware and organizational structures. Due to the recent improvement of the computing power of mobile devices, mobile users may now also act as service providers. The authors design a service-oriented...

    Auto-completion for Executable Business Process Models

    This paper presents an auto-completion mechanism for supporting the creation of executable business process models. Currently, process modeling tools provide only little support to identify the relevant services that are needed to execute the process model - the selection of appropriate services is left to the skills of the modeler....

    Block Cache for Embedded Systems

    In the light of increasing area, big on chip memories are becoming more and more affordable. In coming multi-core systems they are also a necessity to cope with the increasing memory bandwidth pressure towards external memories. The authors show that block caches alone can already outperform instruction caches of the...

    Efficient Resource Utilization for an Extensible Processor Through Dynamic Instruction Set Adaptation

    State-of-the-art ASIPs (Application Specific Instruction set Processors) achieve a significant speedup by combining dedicated hardware accelerators with well-established general purpose processors. Whereas traditional ASIPs are vendor-targeted towards a specific application domain, modern ASIPs allow the designer to define individual pre-fabrication customizations, thus improving the degree of specialization towards the actual...

    User-friendly Semantic Annotation in Business Process Modeling

    Current problems in Business Process Management consist of terminology mismatches and unstructured and isolated knowledge representation in process models. Semantic Business Process Management aims at overcoming many of those weaknesses of Business Processes Management through the use of explicit semantic descriptions of process artifacts. However, this vision has a prerequisite:...

    Rule-based Autocompletion of Business Process Models

    Several methods based upon textual programming languages or graphical notations have been proposed for manual modeling of business process models. But since manual process modeling is time-consuming and increases the amount of structural modeling errors, the authors aim at supporting the user during the process modeling phase. In this paper,...

    Integration of heterogeneous BPM Schemas: The Case of XPDL and BPEL

    Heterogeneous Business Process Modeling (BPM) schemas have been a problem for business process management throughout the last couple of years. Methodological guidance is needed in order to consolidate concurrent schema proposals especially in the BPM area. This paper discusses the applicability of schema integration for this purpose. The authors use...
