The process of creating e-learning contents using reusable learning objects (LOs) can be broken down in two sub-processes: LOs finding and LO sequencing. Although semiautomatic to...
Inspection techniques are widely used during systems design as a supplement to empirical evaluations of usability. Psychology-based inspection techniques could give important insi...
This paper considers the problem of scheduling two-operation non-preemptable jobs on two identical semiautomatic machines. A single server is available to carry out the first (or ...
We consider a quadratic programming (QP) problem (Π) of the form min xT Cx subject to Ax ≥ b where C ∈ Rn×n + , rank(C) = 1 and A ∈ Rm×n , b ∈ Rm . We present an FPTAS ...
We study the power assignment problem in radio networks, where each radio station can transmit in one of two possible power levels, corresponding to two ranges – short and long....
