Evolutionary White-Box Software Test with the EvoTest Framework: A Progress Report

2009

Evolutionary white-box software testing has been extensively researched but is not yet applied in industry. In order to investigate the reasons for this, we evaluated a prototype version of a tool, representing the state-of-the-art for evolutionary structural testing, which is targeted at industrial use. The focus was on the applicability of the structural test tool in the industrial context and not on assessment of the test cases generated. Four case studies, each consisting of an embedded software module from the automotive industry implemented in the C language, were evaluated with the tool. The case studies had to be customized to cope with the limitations of the tool and in all, test c…

Political Instability, Transnational Tourist Companies and Destination Recovery in the Middle East after 9/11

2007

The change and mobility of images is one of the main forces influencing contemporary tourism. Tourists decide whether to travel to a destination or not on the basis of changing destination images. This is especially true for tourism destinations in the Middle East and North Africa after 9/11. But how do security related destination images affect the actions of the supply side agents? While the impact of incidents of violent political unrest and the consequent changes in destination images on tourist behaviour has been subject to wide academic research, there is a lack of similar studies concerning the supply side. The interdependencies and interactions of transnational hotel companies, loca…

Isolated bladder exstrophy associated with a de novo 0.9 Mb microduplication on chromosome 19p13.12

2012

BACKGROUND: The exstrophy-epispadias complex (BEEC) is a urogenital birth defect of varying severity. The causes of the BEEC are likely to be heterogeneous, with individual environmental or genetic risk factors still being largely unknown. In this study, we aimed to identify de novo causative copy number variations (CNVs) that contribute to the BEEC. METHODS: Array-based molecular karyotyping was performed to screen 110 individuals with BEEC. Promising CNVs were tested for de novo occurrence by investigating parental DNAs. Genes located in regions of rearrangements were prioritized through expression analysis in mice to be sequenced in the complete cohort, to identify high-penetrance mutati…

The Implementation of Dual VET in Spain: An Empirical Analysis

2019

This paper provides a brief overview of how Dual VET was implemented in the Spanish VET system. Dual VET was first regulated in Spain by the end of 2012 with the aim to replace the existing work experience module (FCT) within formal VET. However, companies have hardly contributed to its development, and the educational administrations that mandated it did not support its anchorage in the economy, while forcing VET schools and teachers to introduce it. This has resulted in an example of how not to implement educational reforms. We will use our own empirical research as well as secondary analysis of empirical studies to analyze the views of VET teachers on the whole process and the added valu…

An AER handshake-less modular infrastructure PCB with x8 2.5Gbps LVDS serial links

2014

Nowadays spike-based brain processing emulation is taking off. Several EU and others worldwide projects are demonstrating this, like SpiNNaker, BrainScaleS, FACETS, or NeuroGrid. The larger the brain process emulation on silicon is, the higher the communication performance of the hosting platforms has to be. Many times the bottleneck of these system implementations is not on the performance inside a chip or a board, but in the communication between boards. This paper describes a novel modular Address-Event-Representation (AER) FPGA-based (Spartan6) infrastructure PCB (the AER-Node board) with 2.5Gbps LVDS high speed serial links over SATA cables that offers a peak performance of 32-bit 62.5…

On the impact of within-die process variation in GALS-Based NoC Performance

2012

[EN] Current integration scales allow designing chip multiprocessors (CMP), where cores are interconnected by means of a network-on-chip (NoC). Unfortunately, the small feature size of current integration scales causes some unpredictability in manufactured devices because of process variation. In NoCs, variability may affect links and routers causing them not to match the parameters established at design time. In this paper, we first analyze the way that manufacturing deviations affect the components of a NoC by applying a new comprehensive and detailed within-die variability model to 200 instances of an 8¿8 mesh NoC synthesized using 45 nm technology. Later, we show that GALS-based NoCs pr…

Smart interface devices for distributed generation in smart grids: The case of islanding

2017

With the increasing presence of distributed generators (DGs), the implementation of a smart sensors and actuators network in distribution grids has become crucial for different monitoring, management and protection functionalities. For DGs monitoring and control, sensors and actuators are usually embedded in so-called interface devices (IDs) or interface protection systems (IPSs). Existing IDs lack in communication interfaces both to the electrical energy Distribution System Operators (DSOs) and to the DGs inverter. In this framework, the authors have developed a new ID solution and a proper communication architecture, which allow implementing new smart functionalities based on the interact…

Vibration of damaged beams under a moving mass: theory and experimental validation

2004

Abstract A theoretical and experimental study of the response of a damaged Euler–Bernoulli beam traversed by a moving mass is presented. Damage is modelled through rotational springs whose compliance is evaluated using linear elastic fracture mechanics. The analytical solution is based on the series expansion of the unknown deflection in a basis of the beam eigenfunctions. The latter are calculated using the transfer matrix method, taking into account the effective mass distribution of the beam. The convective acceleration terms, often omitted in similar studies, are considered here for a correct evaluation of the beam–moving mass interaction force. The analytical solution is then validated…
