Goals form a declarative description of the desired end result of (part of) an orchestration. A goal-oriented orchestration language is an orchestration language in which these goals are part of the language. The advantage of using goals explicitly in the language is added flexibility in handling failures. In this paper, we investigate how goal-oriented mechanisms for handling failures compare ...

This paper proposes a modeling framework that provides rigorous concepts for conducting early organizational requirements analysis. The aim is to allow business analysts to produce an organizational model that precisely captures the knowledge of an organization and of its business processes. To this end, the framework offers a conceptual meta-model that identifies constructs that enable capturi...

ÐRequirements engineering is concerned with the elicitation of high-level goals to be achieved by the envisioned system, the refinement of such goals and their operationalization into specifications of services and constraints and the assignment of responsibilities for the resulting requirements to agents such as humans, devices, and software. Requirements engineering processes often result in ...

Protein calorie malnutrition is a concern in critically ill patients. Prospective studies to define the ideal calorie/protein intake to administer not only to meet requirements but also to change outcome are lacking. Strack van Schijndel and colleagues have observed an improvement in survival when patients reach the calorie target according to indirect calorimetry and a protein intake of greate...

Recommenders assist users to find items of their interest in large datasets. Effective recommenders enhance users satisfaction and improve customers loyalty. Current recommenders concentrate on the immediate recommendations’ value and are appraised as such but it is not adequate for long term goals. In this study, we propose long term goal recommenders that satisfy current needs of users while ...

We address the problem of identifying key domain concepts automatically from an unannotated corpus of goal-oriented human-human conversations. We examine two clustering algorithms, one based on mutual information and another one based on Kullback-Liebler distance. In order to compare the results from both techniques quantitatively, we evaluate the outcome clusters against reference concept labe...

Nowadays, systems are growing in power and in access to more resources and services. This situation makes it necessary to provide user-centered systems that act as intelligent assistants. These systems should be able to interact in a natural way with human users and the environment and also be able to take into account user goals and environment information and changes. In this paper, we presen...

This paper argues that autonomic systems need to make their distributed monitoring adaptive in order to improve their “comprehensive” resulting quality; that means both the Quality of Service (QoS), and the Quality of Information (QoI). Thus, we propose a methodology to design monitoring adaptation based on high level objectives (goals) related to the management of quality requirements. One of ...

The paper presents calculations for the radiation of a loop antenna wrapped around a metallic cylinder into a conductive medium. The problem has been solved analytically by using Fourier transform and Bessel functions. The evaluation of the analytical solution, involves the use of exponentially scaled Bessel functions, and FFT to evaluate inverse Fourier transform, with all computations done in...
