Évaluation de l’impact de fautes matérielles sur le logiciel par Model Checking
D. BASSOLE, Jean-Louis Lanet, and Axel Legay
La mutation de programme dû à un défaut d'environnement est susceptible de générer des problèmes de sécurité comme la non exécution de procédure de vérification, le saut de bloc d'instruction etc.. Pour les éradiquer il est nécessaire de comprendre les effets de ces perturbations sur le logiciel. Souvent les travaux explorent les effets au niv(...)

Toward a Pattern-based e-learning software design approach
Tonguim Ferdinand Guinko, Laurence Capus, Hatem Ben Sta
Enthusiasm for educational software sometimes hides some real problems, which have some negative repercussions on the efficiency and the quality of learning undertaken by learners. Among those problems are the poor analysis, the poor design and the ignorance of the pedagogical theoretical aspects in the design process. This work proposes an e-(...)

Three Thresholds for the Efficiency in Energy Management in WSN
Yacouba Ouattara, Christophe Lang, and Adel Elgaber
Nowadays, the domain of sensor networks constitutes a very active research field. People are using a lot of
low cost networks. As a result, they are facing an important energy management problem. Consequently, Researchers have tried to ensure long life to networks [1]-[8]. LEACH, PEGASUS, TEEN and APTEEN are pioneers in the reduction of WSN e(...)

Remainder approach for the computation of digital straight line subsegment characteristics
JSD Ouattara, E Andres, G Largeteau-Skapin, R Zrour, TMY Tapsoba
Given a digital straight line D of known characteristics (a, b, c), and given two arbitrary discrete points A (x a, y a) and B (x b, y b) of it, we are interested in computing the characteristics of the digital straight segment (DSS) of D delimited by the endpoints A and B. Our method is based entirely on the remainder subsequence S={a x− c mo(...)

Extraction des connaissances dans un wiki sémantique : apport des ontologies dans le prétraitement
Y. Traoré, S. Malo, C. T. Diop, M. Lo, S. Ouaro
Dans cet article, nous proposons une approche d’extraction des connaissances dans un wiki sémantique. Les pages du wiki sont annotées par une ontologie décrivant les connaissances socioculturelles des communautés ouest-africaines. Notre démarche consiste à extraire, à partir des pages du wiki, les tags (mot clés) qui y sont associés librement(...)

Domain matters : bringing further evidence of the relationships among anti-patterns, application domains, and quality-related metrics in Java mobile apps.
Mario Linares Vasquez, Sam Klock, Collin McMillan, Aminata Sabane, Denys Poshyvanyk, Yann-Gael Gueheneuc
Some previous work began studying the relationship between application domains and quality, in particular through the prevalence of code and design smells (e.g., anti-patterns). Indeed, it is generally believed that the presence of these smells degrades quality but also that their prevalence varies across domains. Though anecdotal experiences(...)

Information Access Assistant Service (IAAS)
Kisito Kaboré, Oumarou Sie, Florence Sèdes, André Péninou
With the great diffusion of multimedia information on
the web, plenty of solutions are proposed to solve the web users’
cognitive overload. Despite the multitude of solutions, the web
users are still looking for more and more simple assistant in web
using. In this paper we present an information adaptation system
using characteristics of(...)

Performances of neural networks and LDPC decoders for OFDM high speed transmission in optical fiber
Serge Roland Sanou, François Zougmoré, Marcel Kebré, Zacharie Koalaga, Ali Doumounia
This paper presents a comparison of the performances of coded OFDM (Orthogonal Frequency Division Multiplexing) for optical broadband transmission using Random Neural Network (RNN), a variant of RNN, Soft Decision Decoding (SDD) and LDPC channel decoding techniques. The performance evaluation is based firstly on the Error Vector Magnitude (EVM(...)

BER reduction for mQAM high-speed transmission in optical fiber networks using convolutional, BCH, RS and LDPC error correcting codes
S. R. Sanou, F. Zougmore, Z. Koalaga, M. Kebré
A comparative study of digital m-ary Quadrature Amplitude Modulation (mQAM) channel coding signals for optical high-speed transmission is presented in this article. The needs to transmit information at high speed are topical and relevant to the images, the sounds, and data of any kind, etc. The photonic networks are the subject of much researc(...)

A Study on the relation between antipatterns and the cost of class unit testing
Aminata Sabané, Massimiliano Di Penta, Giuliano Antoniol, Yann-Gael Gu_eh_eneuc.
Antipatterns are known as recurring, poor design choices, recent and past studies indicated that they negatively affect software systems in terms of understand ability and maintainability, also increasing change-and defect-proneness. For this reason, refactoring actions are often suggested. In this paper, we investigate a different side-effect(...)

A SVM-based incremental anti-pattern detection approach.
Abdou Maiga, Nasir Ali, Neelesh Bhattacharya, Aminata Saban_e, Yann-Gael Gueheneuc, Giuliano Antoniol, Esma Ameur. SMURF
In current, typical software development projects, hundreds of developers work asynchronously in space and time and may introduce anti-patterns in their software systems because of time pressure, lack of understanding, communication, and-or skills. Anti-patterns impede development and maintenance activities by making the source code more diffi(...)

Support vector machines for anti-pattern detection
Abdou Maiga, Nasir Ali, Neelesh Bhattacharya, Aminata Saban_e, Yann-Gael Gu_eh_eneuc, Giuliano Antoniol, Esma A_meur
Developers may introduce anti-patterns in their software systems because of time pressure, lack of understanding, communication, and--or skills. Anti-patterns impede development and maintenance activities by making the source code more difficult to understand. Detecting anti-patterns in a whole software system may be infeasible because of the(...)

Improving bug location using binary class relationships
Nasir Ali, Aminata Saban_e, Yann-Gael Gueheneuc, Giuliano Antoniol
Bug location assists developers in locating culprit source code that must be modified to fix a bug. Done manually, it requires intensive search activities with unpredictable costs of effort and time. Information retrieval (IR) techniques have been proven useful to speedup bug location in object-oriented programs. IR techniques compute the text(...)
