Hypothesis test for changes in variance using a statistic based in P-values in a time series of normal independent observations. por Armendáriz Hernández, Samuel Uriel

“…The power of the test was simulated using Monte Carlo simulation, and the results were compared with the Chen test (1997) to prove its efficiency. Time series analysts might find the test useful to address homoscedasticity studies were at most one change might be involved.…”

Models and algorithms for transit network planning por Ibarra Rojas, Omar Jorge

“…We design a mixed integer linear programming formulation (MILP) for SBT considering constraints such as bounds of separation times between consecutive trips and departure time dispersion along the planning period. We prove that SBT is NP-hard. Nevertheless, the mathematical structure of SBT MILP allow to define a preprocessing stage based on constraint propagation leading to the elimination of a high percentage of decision variables and constraints…”

Wear resistance of thermal spray WC-Co-VC nanostructured coatings por Cabral Miramontes, José Ángel, Gaona Tiburcio, Citlalli, Velasco Tellez, Abraham, Poblano Salas, Carlos, Almeraya Calderón, Facundo

“…The combination of VC additions and a bimodal WC particle size distribution in the WC-Co coatings proved successful in increasing their mechanical properties, which permitted the coatings processed in this work to show better mechanical properties than those reported in the literature for coatings having exclusively a bimodal WC particles size distribution or those only doped with VC additions. …”

Nutrition and Feeding of the Brazilian Pink Shrimp Farfantepenaeus paulensis por O. Cavalli, Ronaldo, C. Abreu, Paulo, Wasielesky, Wilson

“…In recent years, however, renewed interest in the farming of the pink shrimp Farfantepenaeus paulensis insouthern Brazil has been stimulated by its market value and higher tolerance to comparatively low temperature levels.F. paulensis proved relatively easy to rear through the larval stages but juveniles reared in ponds perform poorly onformulated feeds, usually displaying low growth rates. …”
