Ecuaciones de optimalidad para el criterio del costo promedio sensible al riesgo en procesos de decisión markovianos sobre un espacio finito por Alanís Durán, Alfredo

“…Next, in Chapter 2 a fundamental theorem by Howard and Matheson (1972), as well as a recent extension on the characterization of the optimal average cost in terms of a single optimality equation are analyzed; such results require that, under the action of any stationary policy, every state can be visited with positive probability regardless of the initial sate, and the arguments used in this work emphasize the central role of that communication property. The presentation continues in Chapter 3 studying a recent theorem on the existence of solutions to the optimality equation for ‘small’values of the risk-sensitivity coefficient, which was derived under the assumption that there exists a state that can be always reached with positive probability under the action of any stationary policy; the derivation presented in this work highlights the fundamental role of such an accessibility condition. …”

New Technologies in Extrusion Process for Shrimp Feed por Muñoz, Osvaldo

“…In addition a limited availability of water for the sustainable farming of shrimp, has routed this business to intensive raise where the levels of pollution play a very important role. This is why the feed must also generate lower levels of waste.It is well known that the extrusion process compared with the pelleting process, produce better nutritional quality feed, but in the particular case of shrimp, where a feed of high density and stable in the water is required, the extrusion by itself is not able to achieve these levels of desired density.The main characteristics of the shrimp feed are:- Water Stability, Digestibility, Quick sinking, Smaller size of the pellet, Reduces pollution in the water, - Lowering costs in the feed and OtherAlthough the extrusion process requires a highest investment and also the operational costs are higher than the pelleting process, if the extrusion process has the appropriate technology for densification, it would be much cheaper with a much greater profit than the pelleting process and most importantly, with a better quality feed as a result.In this work we show the latest technological advances in this direction to achieve a feed for shrimp in high quality and low cost through the extrusion process.…”

INPUT HYPOTHESIS FOR OR AGAINST OUTPUT HYPOTHESIS? por García, Laura

“…  According to Ellis one of the major contributions of SLA research to teacher' practice is the finding that differences between input and intake depends on the learner. Also related to the role of learners in the acquisition process, Pica establishes that the negotiation between the learners and their interlocutors gives the former time and opportunity to catalogue the input in order to be able to process it. …”

Turbulent Kinetic Energy in the Energy Balance of a Solar Flare por Kontar, E. P., Pérez, J. E., Harra, L. K., Kuznetsov, A. A., Emslie, A. G., Jeffrey, N. L. S., Bian, N. H., Dennis, B. R.

“…We show that the spatial location of, and timing of the peak in, turbulent kinetic energy together provide persuasive evidence that turbulent energy may play a key role in the transfer of energy in solar flares. Although the kinetic energy of turbulent motions accounts, at any given time, for only ∼ð0.5–1Þ% of the energy released, its relatively rapid (∼1–10 s) energization and dissipation causes the associated throughput of energy (i.e., power) to rival that of major components of the released energy in solar flares, and thus presumably in other astrophysical acceleration sites…”
