XBeach is an open source, freely available two-dimensional code, developed to solve hydrodynamic and morphological processes in the coastal environment. In this paper the code is applied to ten different test cases specific to hydraulic problems encountered in the fluvial environment, with the purpose of proving the capability of XBeach in rivers. Results show that the performance of XBeach is ...

Many anonymous applications offer unconditional anonymity to their users. However, this can provoke abusive behavior. Dissatisfied users will drop out or liability issues may even force the system to suspend or cease its services. Therefore, controlling abuse is as important as protecting the anonymity of legitimate users. However, designing such applications is no sinecure. This paper presents...

The performance of a case-based reasoning system often depends on the suitability of an underlying similarity (distance) measure, and specifying such a measure by hand can be very difficult. In this paper, we therefore develop a machine learning approach to similarity assessment. More precisely, we propose a method that learns how to combine given local similarity measures into a global one. As...

In large-volume spaces such as atria and covered malls, smoke management systems are often an important aspect of fire protection, with their primary goal being to ensure that the impact of smoke and heat on occupants is not life threatening (NFPA 92B1). This involves keeping the height of the smoke layer above the highest level of occupancy for a defined period, longer than the expected time t...

Visualization is among the most powerful of data analysis techniques and is readily available in standalone systems or components of everyday software packages. In recent years much work has been done to design and develop visualization systems with reduced entry and usage barriers in order to make visualization available to the masses. Here we describe a novel application of case-based reasoni...

In this paper we describe a case-based reasoning application developed for aiding engineers in the design of chemical absorption plants. Based on the notion of flow sheet, the paper describes how the application uses a highly structured representation of cases and similarity criteria based on chemical knowledge for designing solutions following an interactive case-based reasoning approach.

The derivation of system test cases for product families is difficult due to variability in the requirements, since each variation point multiplies the number of possible behaviors to be tested. This paper proposes an approach to develop domain test cases from use cases that contain variabilities and to derive application test cases from them. The basic idea to avoid combinatorial explosion is ...

In this paper, we show how we have applied the Clinical Narrative Temporal Relation Ontology (CNTRO) and its associated temporal reasoning system (the CNTRO Timeline Library) for automatically identifying, ordering, and calculating the duration of temporal events within adverse event report narratives. The Objective of this research is to evaluate the feasibility of the CNTRO Timeline Library u...

Self-adaptivity allows software systems to autonomously adjust their behavior during run-time to reduce the cost complexities caused by manual maintenance. In this paper, a framework for building an external adaptation engine for self-adaptive software systems is proposed. In order to improve the quality of selfadaptive software systems, this research addresses two challenges in self-adaptive s...

Test result verification is always a costly task for embedded system testing. This paper presents a systematic process to develop verification patterns and use these patterns to verify test results for state-based real-time/embedded systems. The verification patterns are organized into an object-oriented verification framework so that it can be adaptive to changes rapidly The verification patte...
