    • Adaptive local search approach for the timetable scheduling problem 

      Hadjidj, Drifa; Hadjidj, Rachid; Drias, Habiba ( Institute of Electrical and Electronics Engineers Inc. , 2017 , Conference Paper)
      In this paper, we present a new Adaptive Local Search approach (ALS) and its implementation for the NP hard Timetable Scheduling Problem. This approach uses graph heuristics to generate the initial solution and the Aspiration ...

    • An automated approach to translate a biological process from ODEs into graphical hybrid functional Petri Nets 

      Mecheter, Imene; Hadjidj, Rachid; Foufou, Sebti ( Institute of Electrical and Electronics Engineers Inc. , 2017 , Conference Paper)
      The study of biological systems is growing rapidly, and can be considered as an intrinsic task in biological research, and a prerequisite for diagnosing diseases and drug development. The integration of biological studies ...

    • Cluster validity index based on Jeffrey divergence 

      Ben Said, Ahmed; Hadjidj, Rachid; Foufou, Sebti ( Springer London , 2017 , Article)
      Cluster validity indexes are very important tools designed for two purposes: comparing the performance of clustering algorithms and determining the number of clusters that best fits the data. These indexes are in general ...

    • Edge guided total variation for image denoising 

      Ben Said, Ahmed; Hadjidj, Rachid; Foufou, Sebti; Abidi, Mongi ( Institute of Electrical and Electronics Engineers Inc. , 2017 , Conference Paper)
      In this paper, we present a novel denoising algorithm based on the Rodin-Osher-Fatemi (ROF) model. The goal is to ensure maximum noise removal while preserving image details. To achieve this goal, we developed a new edge ...

    • Modeling and Simulation of Bio-pathways using Hybrid Functional Petri Nets 

      Mecheter, Imene (2017 , Master Thesis)
      The study of biological systems is growing rapidly, and can be considered as an intrinsic task in biological research and a prerequisite for diagnosing diseases and drug development. The integration of biological studies ...

    • Multispectral image denoising with optimized vector non-local mean filter 

      Ben Said, Ahmed; Hadjidj, Rachid; Melkemi, Kamal Eddine; Foufou, Sebti ( Elsevier Inc. , 2016 , Article)
      Nowadays, many applications rely on images of high quality to ensure good performance in conducting their tasks. However, noise goes against this objective as it is an unavoidable issue in most applications. Therefore, it ...

    • Sentiment Analysis as a Service: A Social Media Based Sentiment Analysis Framework 

      Ali, Kashif; Dong, Hai; Bouguettaya, Athman; Erradi, Abdelkarim; Hadjidj, Rachid ( Institute of Electrical and Electronics Engineers Inc. , 2017 , Conference Paper)
      We propose a 'Sentiment Analysis as a Service' (SAaaS) framework that abstracts sentiments from social information services, analyses and transforms into useful information. We propose a dynamic service composition mechanism ...

    • Social-Sensor Cloud Service Selection 

      Aamir, Tooba; Bouguettaya, Athman; Dong, Hai; Erradi, Abdelkarim; Hadjidj, Rachid ( Institute of Electrical and Electronics Engineers Inc. , 2017 , Conference Paper)
      We propose a new framework for social-sensor cloud services selection based on spatio-textual correlation between user's query and service. The proposed research defines a formal social-sensor cloud service model that ...
