  • On end-to-end scheduling in wireless cellular networks 
    Saad, Walid; Dawy, Zaher; Sharafeddine, Sanaa (IEEE, 2018-07-04)
    Wireless cellular networks are required to meet the stringent QoS requirements of emerging data services. To efficiently utilize the available radio resources, we propose a new resource allocation algorithm for services ...
  • On entropy weak solutions of Hughes’ model for pedestrian motion 
    El-Khatib, Nader; Goatin, Paola; Rosini, Massimiliano D. (2017-01-10)
    We consider a generalized version of Hughes’ macroscopic model for crowd motion in the one-dimensional case. It consists in a scalar conservation law accounting for the conservation of the number of pedestrians, coupled ...
  • On hierarchical collaborative content distribution over communication networks 
    Mouawad, Amer; Sharafeddine, Sanaa (IEEE, 2018-07-05)
    Content distribution applications such as video streaming, file sharing, and network gaming are posing strict requirements on the development and enhancement of communications technologies, architectures, and protocols. ...
  • On Hughes' Model for Pedestrian Traffic 
    Kaldawi, Fadi J (Lebanese American University, 2020-07-09)
    In this thesis, we explore the modeling and application of the pedestrian fl w model proposed by Roger L. Hughes in 2002, a system of a hyperbolic conservation law to describe crowd densities (ρ) and an Eikonal equation ...
  • On Leveraging the Computational Potential of Fog-Enabled Vehicular Networks 
    Sorkhoh, Ibrahim; Ebrahimi, Dariush; Sharafeddine, Sanaa; Assi, Chadi (ACM, 2019-12-10)
    The advent of autonomous vehicles demands powerful processing capabilities of on-board units to handle the dramatic increase of sensor data used to make safe self-driving decisions. Those com- putational resources, being ...
  • On Network Planning for Video Services Over IP Networks 
    Sharafeddine, S. (2016-03-02)
    Video transmission over IP requires very high data rate for a good performance. Variable bit rate (VBR)-coded video is more popular than constant bit rate (CBR)-coded video due to its statistical multiplexing gain and ...
  • On Power-Constrained System-on-chip Test Scheduling Using Precedence Relationships 
    Harmanani, Haidar M.; Salamy, Hassan A. (IEEE, 2017-03-29)
    This paper presents an efficient method to determine minimum SOC test schedules based on simulated annealing. The problem is solved using a partitioned testing scheme with run to completion that minimizes the number of ...
  • On scalable parallel recursive backtracking 
    Abu-Khzam, Faisal N.; Daudjee, Khuzaima; Mouawad, Amer E.; Nishimura, Naomi (2015-12-07)
    Supercomputers are equipped with an increasingly large number of cores to use computational power as a way of solving problems that are otherwise intractable. Unfortunately, getting serial algorithms to run in parallel to ...
  • On sensor selection in mobile devices based on energy, application accuracy, and context metrics 
    Taleb, Sireen; Abbas, Nadine; Hajj, Hazem; Dawy, Zaher (IEEE, 2022-11-25)
    Continuously collecting sensor data on mobile devices helps in capturing important contextual information related to the user location, activity, and surrounding environment. This contextual information is required by ...
  • On Single Source Reachability Improvement 
    Alkak, Hashem (Lebanese American University, 2023-02-02)
    The problem of augmenting a given network, or graph, via edge-additions for improved reachability from a given source node is considered. We formulate and study the following Single Source Reachability Improvement problem ...
  • On special-purpose hardware clusters for high-performance computational grids 
    Abu-Khzam, Faisal N.; Lehrter, Jeanne M.; Bouldin, Donald W.; Langston, Micheal A.; Peterson, Gregory D. (2017-03-22)

  • On the complexity of bilinear computations 
    Takche, Jean Halim (Pennsylvania State University, 2018-04-17)
    Arithmetic complexity theory is the study of the minimum number of non-scalar multiplications required to compute a set of bilinear forms. One can show that we can restrict ourselves to bilinear algorithms. Brockett and ...
  • On the complexity of multi-parameterized cluster editing 
    Abu-Khzam, Faisal (2018-04-23)
    The Cluster Editing problem seeks a transformation of a given undirected graph into a disjoint union of cliques via a minimum number of edge additions or deletions. A multi-parameterized version of the problem is studied, ...
  • On the complexity of QoS-Aware service selection problem 
    Abu-Khzam, Faisal N.; Bazgan, Cristina; El Haddad, Joyce; Sikora, Florian (Springer, 2017-03-16)

  • On the complexity of various parameterizations of common induced subgraph isomorphism 
    Abu-Khzam, Faisal N.; Bonnet, Edouard; Sikora, Florian (Springer, 2017-03-16)
    Maximum Common Induced Subgraph (henceforth MCIS) is among the most studied classical NPNP -hard problems. MCIS remains NPNP -hard on many graph classes including bipartite graphs, planar graphs and k-trees. Little is ...
  • On the Computations of Gas-Solid Mixture Two-Phase Flow 
    Touma, R.; Zeidan, D. (2016-04-07)
