    • Email Authorship Attribution In Cyber Forensics 

      Hadjidj, Rachid ( Hamad bin Khalifa University Press (HBKU Press) , 2014 , Conference Paper)
      Email is one of the most widely used forms of written communication over the Internet, and its use has increased tremendously for both personal and professional purposes. The increase in email traffic comes also with an ...

    • Gravitational weighted fuzzy c-means with application on multispectral image segmentation 

      Ben Said, Ahmed; Hadjidj, Rachid; Foufou, Sebti ( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)
      This paper presents a novel clustering approach based on the classic Fuzzy c-means algorithm. The approach is inspired from the concept of interaction between objects in physics. Each data point is regarded as a particle. ...

    • Lascada: A novel scalable topology for data center network 

      Chkirbene, Zina; Hadjidj, Rachid; Foufou, Sebti; Hamila, Ridha ( IEEE , 2020 , Article)
      The growth of cloud-based services is mainly supported by the core networking infrastructures of large-scale data centers, while the scalability of these services is influenced by the performance and dependability ...

    • Total Variation for Image Denoising Based on a Novel Smart Edge Detector: An Application to Medical Images 

      Ben Said, Ahmed; Hadjidj , Rachid; Foufou, Sebti ( Springer New York LLC , 2019 , Article)
      In medical imaging applications, diagnosis relies essentially on good quality images. Edges play a crucial role in identifying features useful to reach accurate conclusions. However, noise can compromise this task as it ...

    • Towards model-based management of database fragmentation 

      Ali, Asim; Jia, Rui; Erradi, Abdelkarim; Abdelwahed, Sherif; Hadjidj, Rachid ( USENIX Association , 2013 , Conference Paper)
      The performance of a database can significantly deteriorate due to the fragmentation of data/index files. Manual database defragmentation and performance optimization remain time consuming and even infeasible as it requires ...

    • Vector anisotropic filter for multispectral image denoising 

      Ben Said, Ahmed; Foufou, Sebti; Hadjidj, Rachid ( SPIE , 2015 , Conference Paper)
      In this paper, we propose an approach to extend the application of anisotropic Gaussian filtering for multi- spectral image denoising. We study the case of images corrupted with additive Gaussian noise and use sparse matrix ...
