Modeling Attack-Defense Trees’ Countermeasures using Continuous Time Markov Chains
ADTrees (Attack-Defense Trees) are graphical security mod- eling tools used to logically represent attack scenarios along with their corresponding countermeasures in a user-friendly way. Many researchers nowadays use ADTrees to represent attack scenarios and perform quan- titative as well as qualitative security assessment. Among all di erent existing quantitative security assessment techniques, CTMCs (Continu- ous […]

Dual Color-Image Discriminators Adversarial Networks for Generating Artificial-SAR Colorized Images from SENTINEL-1 Images
In this paper, we introduce a new generative adversarial network (GAN) with dual image-color discriminators, to predict Artificial-SAR colorized images from SAR ones (Sentinel-1). Based on the conventional architecture of GANs, we employ an additional color discriminator that evaluates the differences in brightness, contrast, and major colors between images, while the image discriminator compares texture […]

Photocatalytic degradation and photo-generated hydrophilicity of Methylene Blue over ZnO/ZnCr2O4 nanocomposite under stimulated UV light irradiation
This paper deals with the relationship between photocatalysis and photo-generated hydrophilicity under UV light irradiation of ZnO/ZnCr2O4 nanocomposite film prepared via spray pyrolysis method. XRD investigations indicate that the nanocomposite sample show the presence of würtzite ZnO phase having crystallites oriented preferentially along c-axis with the presence of a secondary phase spinel of ZnCr2O4. Indeed, […]

The direct and indirect risk impacts on remittances: A cross‐regional specific effects
The main purpose of this paper is to study determinants of workers’ remittances especially the impact of country risk based on a regional comparison of 121 countries subdivided into six areas over the period 1984–2015. We consider possible direct and indirect effects of different risk indexes. We particularly focus on the comparison of the regional […]

Designing universal visuotactile pictograms for orientation maps
Pictograms are used in all domains of our daily life, in orientation maps in particular. They can be depicted visually or tactually for blind people. The problem is that these existing pictograms are not standardized. The aim of this study was to develop a range of visuotactile orientation pictograms, which would be understandable by adults, […]

Bi-Objective Indirect Optimization of Robotic Transportation Task Assignment Based on Auction Mechanism
Flexible manufacturing systems (FMS) are used to ensure the production of several products using the same set of production tools. Transportation tasks using robots are introduced in order to increase the routing flexibility of the FMS. Several researchers are interested in the optimization of the production planning but few of them considered the transportation planning. […]

A Simulated Multi-Objective Model for Flexible Job Shop Transportation Scheduling
This paper proposes a new dynamic algorithm based on simulation approach and multi-objective optimization to solve the FJSP with transportation assignment. The objectives considered in scheduling jobs and transportation tasks in a flexible job shop manufacturing system include makespan, robot travel distance, time difference with due date and critical waiting time. The results obtained from […]

Text input tools’ complementarity in immersive virtual environments
This study presents a user test in order to ascertain the advantages and disadvantages of three different text input methods in immersive virtual environment: individual Speech-to-Text, collective Speech-to-Text and a virtual keyboard named Drum-Like Keyboard. We measured participants’ user experience, especially related to usability and utility, in order to offer relevant recommendations to people seeking […]

Automatic generation of building information models from digitized plans
This paper proposes a new approach to creating Building Information (BIM) models of existing buildings from digitized images. This automatic approach is based on three main steps. The first involves extracting the useful information automatically from rasterized plans by using image processing techniques that include segmentation, filtering, dilation, erosion, and contour detection. This information feeds […]

On the use of particle-wall interaction models to predict particleladen flow in 90-deg bends
The objective of this work is to evaluate the capability of different combinations of a turbulence model and a Lagrangian particle tracking (LPT) model integrating a particle-wall interaction (PWI) model to predict particle-laden flow in 90-deg bends, as well as the impact of the PWI model on the prediction of the referred flow. The experimental […]

Sustainable capacitated facility location/network design problem: a Non-dominated Sorting Genetic Algorithm based multiobjective approach
In a highly competitive environment, characterized by shorter product life cycles, mass customization and fluctuating markets, the supply chain network design is considered as one of the most important steps for reducing their costs, increasing their performance, competitiveness and profits. In addition, due to the growing social, governmental and industrial concerns about environmental protection and […]

A Reference Architecture for Smart Building Digital Twin
This paper proposes a software architecture for creating and managing unambiguous descriptions of a Smart Building, allowing its Digital Twin to be deployed. These descriptions include static semantic structural description and dynamic time-series sensors data. Moreover, it is designed to be able to include data from various simulation tools, represented in the same way as […]
