The Declare Service is a YAWL Custom Service that enables decomposing YAWL tasks into DECLARE workflows, i.e. workflows supported by the workflow management system (WfMS) called DECLARE. The goal of this service is to enable a particular kind of flexibility. Chapter 6 describes a constraint-based approach to workflow models and the ConDec language. This approach, supported by the DECLARE WfMS, ...

Decomposers provide an essential ecosystem service that contributes to sustainable production in rice ecosystems by driving the release of nutrients from organic crop residues. During a single rice crop cycle we examined the effects of four different crop residue management practices (rice straw or ash of burned straw scattered on the soil surface or incorporated into the soil) on rice straw de...

This paper introduces a methodology for virtual network partitioning in a single node with a generalized processor sharing scheduler. The approach is based on the worst-case service curve provisioning. The true service curve is a function of the number of users and their traffic fluctuations. In this paper, we define a deterministic universal service curve as a lower bound to the true service c...

We study G/G/∞ queues with renewal alternating service interruptions, where the service station experiences up and down periods. The system operates normally in the up periods, and all servers stop functioning while customers continue entering the system during the down periods. The amount of service a customer has received when an interruption occurs will be conserved and the service will resu...

In IT Service Delivery, alignment of service infrastructures to continuously changing business requirements is a primary cost driver, all the more as most severe service disruptions can be attributed to poor change impact and risk assessment. In nowadays service-oriented business environments, services are shared amongst multiple higher-level or composite services, while the highest composition...

The Internet of Things (IoT) aims to connect everyday physical objects the internet. These will produce a significant amount data. traditional cloud computing architecture process data in cloud. As result, needs be communicated This creates number challenges, such as high communication latency between devices and cloud, increased energy consumption during frequent upload bandwidth consumption, ...

Reduced Differental Transform Method (RDTM), which is one of the useful and effective numerical method, is applied to solve nonlinear time-dependent Foam Drainage Equation (FDE) with different initial conditions. We compare our method with the famous Adomian Decomposition and Laplace Decomposition Methods. The obtained results demonstrated that RDTM is a powerful tool for solving nonlinear part...

Mass customization has become one of the key strategies for a service provider to differentiate itself from its competitors in a highly segmented global service market. This paper proposes an interactive service customization model to support individual service offering for customers. In this model, not only that the content of an activity is customizable, but the process model can also be cons...

Software as a Service relies on ubiquitous network access which cannot be assured in mobile scenarios, where varying link quality and user movement impair the always connected property. We approach this challenge by utilizing movable service components between a remote cluster, cloud, or server and the client device using the service. To overcome connection disruptions, service components are m...
