The aim of this paper is to consider as a starting point the value E0 = π in the theorems of semilocal convergence of Kantorovich, Gutiérrez, α−theory of Smale and the α−theory of Wang-Zhao, to compare the convergence conditions obtained. Once set E0, one should calculate the par...

Timetabling is the task of assigning sets of events to periods of time, taking into account resource-constraints and preferences among assignments. This involves combinatorial optimization, time-based planning, in order to realize a highly constrained problems that addresses a mu...

In this paper, we t the hyper-Poisson, and the Mittag-Leer function (MLFD) distributions to data exhibiting over and under dispersion. Three frequency data sets were employed with one exhibiting under-dispersion. We also extend these distributions to GLM situations where we have...

The applications of mobile adhoc network (MANET) are increasing day-by-day due to the flexibility they provide to seamless communication. However MANETS are vulnerable to number of attacks because of properties like non-existing infrastructure, dynamic topology, multihop network...

The microcontrollers are very common components in modern electronic systems. Their using is so widespread that it is almost impossible to work in electronics without coming across it. They are now providing us with a new way of designing circuits. As a result, less complex appli...

We present the structures within group algebras constructed from commutative groups and finite fields. Then we define and construct multicyclic codes in these group algebras. At the end, in the frame of the decoding process, we give a characterization of the locator ideal to the...

In this paper multi-level multi-objective fractional programming problem (ML-MOFP) is considered where some or all of its coefficients in the objective function are rough intervals. At the first phase of the solution approach and to avoid the complexity of the problem, two FP pro...

Considering the factor analysis methods (classical or robust), the data input (data or scaled data), and the running matrix (covariance or correlation) all together, there are 8 combinations. The objective of the study is to give a recommendation for classical and robust factor a...

The human cochlea is the part of the inner ear where acoustic signals are transformed into neural pulses and then signaled to the brain. The cochlear amplifier is essentially a positive feedback loop within the cochlea that amplifies the traveling wave, this mechanism based on th...
