Técnicas de torneado
(2015-06-30)This material presents differents techniques for turning, by means of we can machining the different kinds of cylindrical shapes. -
Técnicas LID para captar agua de lluvia en viviendas unifamiliares
(2017-12-01)En este trabajo se analizaron las posibilidades de implementar tecnologías de bajo impacto (cosecha de agua de lluvia en azoteas y pavimento permeable) en viviendas de tipo unifamiliar. Se cuantificaron los volúmenes de ... -
THE C*-ALGEBRAS ASSOCIATED TO TIME-t AUTOMORPHISMS OF MAPPING TORI
(2006)We find the range of a trace on the K0 group of a crossed product by a time-t automorphism of a mapping torus. We also find a formula to compute the Voiculescu-Brown entropy for such an automorphism. By specializing to the ... -
The flow shop scheduling problem modeled by means of timed place Petrini nets
(2018)The Flow Shop Scheduling Problem (FSSP) is a problem that is commonly found by master production scheduling planners in Flexible Manufacturing Systems (FMS). The planner should find the optimal scheduling to carry out a ... -
The Inverse Behavior of a Reversible One-Dimensional Cellular Automaton Obtained by a Single Welch Diagram
(2006)Reversible cellular automata are discrete dynamical systems based on local interactions which are able to produce an invertible global behavior. Reversible automata have been carefully analyzed by means of graph and matrix ... -
The job shop scheduling problem solved with the travel salesman problem and genetic algorithms
(2013)In this paper we proposed a solution to the JobShop Scheduling Problem using the Traveling Salesman Problem solved by Genetic Algorithms. Different tests are performed to solve the Traveling Salesman Problem with the two ... -
The passive past simple
(2015-06-30)When an action that took place in the past is more important than the person or thing which did the action we use the passive voice in the past simple tense. -
The passive: past simple
(2015-06-30)When an action that took place in the past is more important than the person or thing which did the action we use the passive voice in the past simple tense. -
The stochastic short-term hydrothermal scheduling Problem
(2010)In this document we develop a non linear stochastic integer model formulation for the unit commitment problem of thermal and hydro units to management demand and optimal short-term operation of a hydrothermal electric ... -
The young Ramón y Cajal as a cell-theory dissenter
(2008)The intellectual development of scientists normally traverses several different phases as they mature in their professions. In many cases, strong support of certain ideas and theories gives way to more critical, productive ... -
Thermal model for a microhot plate used in a MEM gas sensor
(2008)A thermal analytical model for a MEM gas sensor is presented and compared with an electrical circuit equivalent model. The objective is to study the temperature performance of the microhot plate configured within a MEM ... -
Thermodynamic study of Iridium in HCl: The effect of concentration
(2014)In this work, the dissolution of iridium was studied through a thermodynamic theoretic study with different concentrations of hydrochloric acid (HCl) and Iridium (Ir). Three different acid conditions and three different ... -
THERMODYNAMIC STUDY OF LEACHED METALS (Cu, Zn AND Ni) FROM WASTE PRINTED CIRCUITS BY ELECTROCHEMICAL METHOD
(2014)A thermodynamic study (Pourbaix type diagrams, using the software Hydra/Medusa) of acid leaching solutions to obtain the electrochemical recovery of Ni, Cu and Zn present in printed circuit boards is reported. Solutions ... -
Three levels analysis of sustainability?s environmental dimension in México
(2015)New world order had increased the necessity to find a sustainable way to live. In a polluting society it is necessary to structure a coexisting strategy which gives to world the opportunity of a sustainable grow up. Due ... -
Three-dimensional structures of RNA obtained by means of knowledge-based interaction potentials.
(2010)We derive a set of effective potentials describing the interaction between pairs of nucleotides that belong to an RNA molecule. Such interaction potentials are then used as the main constituents of a simplified simulation ... -
Tillandsia usneoides as biomonitor of air pollution
(2015)T. usneoides is one of the most employed organisms for biomonitoring atmospheric metals due to its ability to accumulate and retain pollutants, including trace elements. In this article, we review the use of T. usneoides ... -
