A Novel Method of Using API to Generate Liaison Relationships from an Assembly  [PDF]
Arun Tom Mathew, C. S. P. Rao
Journal of Software Engineering and Applications (JSEA) , 2010, DOI: 10.4236/jsea.2010.32021
Abstract: A mechanical assembly is a composition of interrelated parts. Assembly data base stores the geometric models of indi-vidual parts, the spatial positions and orientations of the parts in the assembly, and the relationships between parts. An assembly of parts can be represented by its liaison which has a description of its relationships between the various parts in the assembly. The problem is to not only make the information available but also use the relevant information for making decisions, especially determination of the assembly sequence plan. The method described in this paper ex-tracts the feature based assembly information from CAD models of products and build up liaisons to facilitate assembly planning applications. The system works on the assumption that the designer explicitly defines joints and mating condi-tions. Further, a computer representation of mechanical assemblies in the form of liaisons is necessary in order to automate the generation of assembly plans. A novel method of extracting the assembly information and representing them in the form of liaisons is presented in this paper.
La problemática del agro en la perspectiva de Aldo Ferrer: Una reevaluación del discurso político de "La Economía Argentina" y la práctica histórica durante la apertura nacionalista (1970-1971)
Zeitler,Tomás Elías;
Mundo agrario , 2010,
Abstract: the current importance that the studies have historiographies on the questions of the argentina agro in the xxth century and the growth of works of investigation and of balance sheets on the above mentioned production they generate a propitious context for the critical reappraisal of the contributions that have been done to the history of the argentine agro from the perspective cepalina, mas specifically that one expressed in the wide production of the economist aldo ferrer: his explanation of the agrarian problematics from the analysis of the internal weaknesses of the productive argentina system and the basic failings of the functioning of the capitalist economy constitutes a speech in historical perspective that demonstrates the representations identitarias that the capitalist national sectors had of the argentine agro at the end of the decade of sixty. the analysis of his classic work the economy argentina (1963) allows to argue that in his theoretical and methodological boarding of the economic argentine development the agrarian question occupies the center of the problems that they have afflicted to the productive argentine system during all the 20th century and specially during the stage called of "nationalistic opening" (1970-1971) in which the author had an active political participation as secretary of the treasury of the nation argentina.
Exteriores de los edificios educacionales
Browne,Tomás;
ARQ (Santiago) , 2004, DOI: 10.4067/S0717-69962004005600004
Abstract: pocas veces la arquitectura, en cuanto recrear y construir un mundo, es tan elocuente. para un ni?o, la escuela es la primera visión de lo que es la sociedad más allá de las puertas de su casa; como tal, se convierte en modelo inaugural de las relaciones extra familiares. como lo entendía sánchez ferlosio, es la entrada del ciudadano en el ámbito de lo público (y de lo impersonal), enfrentándolo sistemáticamente a los otros en una marcadora primera experiencia de urbanidad. ?qué pasa hoy con los espacios para la educación, como formadores de sociabilidad? ?ha invadido la familia el territorio social del colegio? ?cómo la arquitectura refleja los cambios de una educación que se acomoda cada vez más a la individualidad de cada estudiante? en un momento en que se han reformulado los roles de padres y profesores, vale la pena preguntarse si las escuelas son las únicas depositarias posibles de la tarea educadora: la necesaria continuidad del proceso más bien hace pensar en una ciudad que es, toda ella, una escuela: abierta, pública, transparente.
Tiempo: cuerpo y memoria, salones y recorridos
Browne,Tomás;
ARQ (Santiago) , 2005, DOI: 10.4067/S0717-69962005005900002
Abstract: la aceleración de nuestra cultura ha hecho que lo que separa pasado, presente y futuro sea de una consistencia cada vez más atenuada e ilegible. y los arquitectos, antes inequívocamente inclinados a la permanencia y a la durabilidad, hoy incorporan la palabra temporal (luego de novedad, joven, reciente) como valor convencional. ?cómo situarse en una época en que la avidez por lo nuevo se transforma, en palabras de javier marías, en "el desdén por lo que existe y la fascinación por lo inexistente"? la arquitectura, entre demoliciones, remodelaciones y persistencias, se resiste a un destino estático: toda ella aparece como registro de lo que ya ha pasado, pero ciertamente es el reflejo de lo que está siendo hoy.
Descubriendo las reglas del juego de la argumentación
Miranda Alonso,Tomás;
EPISTEME , 2007,
Abstract: in this paper it is presented a proposal and an educational experience that was developed with first high school course students (16-17 years old) and also with adults enrolled in popular universities. the aim of the project is to turn the class into a community of rational thinkers who work together to construct, through rigorous dialogue, thoughts and arguments on philosophical issues, to attaint this purpose, the participants, in such community, must work hard to discuss their different points of view, trying to justify them with good reasons, which have pretension of inter-subjetive validity. however, in order to discuss these issues well it is necessary to be acquainted with the rules of this linguistic game, of which, traditionally, logic has occupied a key role. we are proposing that the students get involved in an investigation, whose objective is the discovery of the rules of both formal and informal logic. the investigation should come from the analysis and discussion of concrete arguments, acquired in specific speech contexts where significant problems arise for them, which traditionally form a part of introductory philosophy courses.
Capacidad emprendedora e informalidad en el campo de la economía
Tomás,Páez;
Investigación y Postgrado , 2008,
Abstract: undoubtedly in the socio-economic field informality is a widespread phenomenon that covers a large economic and social diversity and heterogeneity. the results presented in this article enphasize the enterprising capability of this sector and the fundamental axis to set in motion a formalizing strategy. the goal is to contribute to the creation of a more solid and wider entrepreneurs network. the study was carried out in the framework of a programme for technical assistance and consultancy to pyme entrepreneurs of the formal as well as the informal sector. thus a work programme was designed that included a series of workshops to help strengthen and offer capabilities and tools to formal and informal organizations and businesses. the qualitative information resulting from the exhibits, presentations and discussions was furthered using research instruments such as life stories, in depth interviews and case studies. the results of this study are a new way to approach this topic and, from our point of view, a contribution to what is a debate that cannot be delayed any further, in other words the widening and formalization of the entrepreneuers weaving and the sources of employment in venezuela and latin america.
EL ASALTO DE LOS MOTORIZADOS: EL TRANSPORTE MODERNO Y LA CRISIS DEL TRáNSITO PúBLICO EN SANTIAGO, 1900-1927
Errázuriz,Tomás;
Historia (Santiago) , 2010, DOI: 10.4067/S0717-71942010000200002
Abstract: during the first three decades of the twentieth century the city of santiago incorporated three new modes of transportation that profoundly altered the city and the forms of movement within it: the streetcar, the automobile and the bus. beginning with analysis from diverse sources such as municipal archives, statistics, newspapers, automobile, and transportation union magazines, among others, the article attempts to reconstruct the fundamental milestones of the process of motorization and its impact on the daily experience of transport within the city. unlike other manifestations of urban progress, motorized vehicles were typified by their disruptive character that generated multiple conflicts and incompatibilities that then became established as distinctive characteristics of modern transit.

UNA CLASE A MEDIAS: LAS REPRESENTACIONES SATíRICAS DE LOS GRUPOS MEDIOS CHILENOS EN TOPAZE (1931-1970)
Cornejo Cancino,Tomás;
Historia (Santiago) , 2007, DOI: 10.4067/S0717-71942007000200001
Abstract: the political magazine topaze used satire to uncover another side to the sonsolidation of middle class society in mid-twentieth century chile. more than registering simple changes of ideals and mentalities of people who led the country, cartoons and satire texts revealed that there was something else besides new characters in chilean politics. new politicians ended up being even more "gentlemen-acting" than those "gentlemen" they replaced. topaze magazine, focused its attention on the main political parties and showed the ridiculous pretensions of politicians who tried to equate themselves with the elites. the periodical also uncovered the ambitious intentions of political leaders, the inoperative behavior of their followers and the presence of minor quarrels that involved people who wanted to benefit from public funds
