Memoria para optar al título de Ingeniero Civil / Uno de los grandes problemas de las estructuras que se requieren en grandes espacios libres de elementos en su interior o que posean grandes luces, más específicamente en el ámbito minero, es que estos requieren una gran cantidad de acero al necesitar ser sistemas muy robustos. Esto es un problema principalmente económico debido al alto costo asociado a materiales. Es por esto que se han desarrollado estructuras más ligeras para resolver esta problemática. Muchas de estas soluciones, que están siendo aplicadas en el mundo, contemplan sistemas auto-sostenibles de cables y membranas tensadas flexibles. Se abordarán todos los aspectos de los cables y membranas, desde sus componentes básicos, materiales y normas que los controlan, ejemplos destacados y métodos de análisis para luego poder aplicar esta experiencia en un ejemplo práctico de un Stockpile minero, en el cual se comparará una solución convencional con elementos rígidos de acero y método constructivo actual con 2 soluciones aplicando los principios aprendidos de estructuras ligeras. Dentro de la experiencia se verán todas las dificultades que implica tratar con estructuras de cables o membranas a tener en consideración si se desea en un futuro trabajar con estos sistemas. La finalidad de esta memoria es poder extrapolar estas experiencias en la realidad de Chile y más específico para la gran minería. Aquí se entregan las bases y consideraciones que debe tener alguien para poder materializar un proyecto con estas características.

Long bridges tend to develop large deformations under the action of intense dynamical loads such as wind or earthquakes. Unless these deformations are controlled in some fashion, the structure might suffer damage or even collapse. One possible solution to this problem is to apply external forces to the bridge through suspension cables. This work presents an active robust control scheme to suppress the vibrations caused by the vertical ground motion due to an earthquake of a cable-stayed bridge. It is proven both mathematically and through computer simulation that the active nonlinear controller is capable of reducing the amplitude of the vibrations to an arbitrarily small size. This may save the bridge structure during a strong earthquake. It is shown that the control scheme performs satisfactorily even if parts of the system fail during an earthquake. An alternative method to derive the control law using finite elements is also presented. / Graduation date: 1993

La tesi doctoral, que desglossa amb gran documentació i rigor un objecte d'estudi original, analitza el desenvolupament del cable a Espanya i Catalunya partint dels casos internacionals més destacats i significatius: Estats Units d'Amèrica, França, Bèlgica i el Regne Unit. L'autor reflectéis similituts i divergències entre els casos espanyol i català i els models internacionals. A més, també es demostren les particularitats del cas català en el marc espanyol. Les tres variables per guiar l'estudi de cada cas són la societat civil, l'evolució legislativa i la indústria. Espanya i Catalunya presenten en aquest sentit semblances amb els Estats Units d'Amèrica, ja que l'impuls del cable procedeix de la societat civil, en un àmbit eminentment local i en un context d'al·legalitat per la innovació del sector. La dissecció de la realitat internacional del cable i dels referents teòrics per al desenvolupament d'aquesta tecnologia (la millor actualment arran de la interactivitat, la creació de riquesa i ocupació i la dinamització del mercat i de la indústria) és fonamental per aprofundir en les aplicacions a Espanya i Catalunya. El cas català, en el context d'Espanya, presenta com a pedres angulars el consens, el reequilibri territorial i una estructura peculiar d'actors. Operadors (Menta i Telefònica Cable Catalunya), el Comissionat per a la Societat de la Informació, Localret, el CAC, el CECABLE i altres investigacions i institucions configuren un panorama procliu al cable. A més, Catalunya acull uns 60 operadors de cable històric (de cable coaxial i nascuts en època d'al·legalitat), censats en la tesi i estudiats amb detall.Tanmateix, el desenvolupament del cable a Catalunya presenta retards en l'extensió, una realitat que respon a factors com les discrepàncies entre els inversors. Per tant, certes semblances amb els referents internacionals i una estructura peculiar caracteritzen el cable català i l'espanyol. / The doctoral thesis, which is focused with a great documentation and rigour in an original study matter, analizes the development of cable in Spain and Catalonia from the international most important and significative cases: the United States of America, France, Belgium and the United Kingdom. The author establishes similarities and divergences between the Spanish and Catalan cases and the international models. Furthermore, he also shows the particularities of the Catalan case in the Spanish framework. The three variables to guide the study of each case are the civil society, the legislative evolution and the industry. Spain and Catalonia present in this sense similarities with the United States of America, because the launch of cable proceeds from civil society, in a local framework, and in a landscape of allegality caused by the innovation in the sector. The dissection of the international cable reality and the theoric references for the development of this technology (the best nowadays thanks to interactivity, the creation of richness and job and the dinamization of the market and industry) is essential to go ahead in the applications in Spain and Catalonia. The Catalan case, in the framework of Spain, presents as a essential aspects the consensus, the territorial equilibrium and a peculiar structure of actors. Operators (Menta and Telefònica Cable Catalunya), Comissionat per a la Societat de la Informació, Localret, CAC, CECABLE and other researches and institutions configurate a situation which tends to cable. Furthermore, Catalonia has 60 historia cable operators (of coaxial cable and born in allegality era), collected in the thesis and studied with detail.However, the development of cable in Catalonia presents delays in the extension, a reality which responds to factors like discrepancies among investors. Then, some similarities with the international references and a singular structure characterize the Catalan and Spanish cable.

Abstract Along with the increasingly developed computer technology and the wide application of Internet, the use of Internet has been more and more diverse. The function of narrowband network that was limited in the transmission of texts and basic graphs cannot meet the needs of the transmission of multimedia which is consisted of audio, data, video, etc. Therefore, the broadband network has gradually become the mainstream of the network application. The objectives of this study are to discuss the technologies commonly applied in broadband network and to find out how the function of broadband network could be promoted in Taiwan. This study is an industrial policy research. The comparative analysis was conducted on the secondary data collected from both domestic and foreign sources. As shown by the statistics, the number of broadband subscribers has been increasing rapidly in both domestic and foreign areas. This reflects the rising demand of broadband. The conclusions of the study are as follows: 1. The government policy and the industry support make the number of broadband subscriber increase sharply. 2. ADSL and Cable Modem are the technologies commonly adopted among various countries. 3. The economy factor is the primary consideration in adopting the broadband technologies. 4. The content of network is the key factor to the popularity of broadband network. 5. The popularity of broadband network will promote the electronic commerce. There are five suggestions in this study: 1. To install a full optical-fiber network. 2. To accelerate the network into the Internet Protocol one. 3. To cultivate the software professionals. 4. To rationalize the fee of broadband network. 5. To implement the policy on speeding up the construction of broadband network. Key word: Internet, Broadband network, ADSL, Cable Modem

Adult movie channel business is always a very controversial subject in the society. However, there is not so much serious research on it. The main reason is adult channels¡¦ sensitivity. On the one hand, people are curious, because they provide the basic natural desire of the human beings. On the other hand, due to that same reason, people tend to take aversive attitude toward the existence of these channels in the society. Based on this phenomenon, the focus of the research is about how these adult channels operate under the pressure of the society. This research can be divided into two parts: the structure of the theory and the analysis of the case. Through relevant theories, we can verify whether these theories are suitable for this particular industry. Meanwhile, we can present the overview and background of adult movie channel market through a lot of related secondary data. We regard these materials as the foundation of analyzing the case company. About the case analysis part, with the combination of theories and case description, we try to sketch the contours of the actual operations of adult movie channel. Because the operation of adult movie channels is based on cable TV, this research will talk about adult movie channel market in terms of cable TV and probe into the market of adult movie channel. From the case study, it can be found that the greatest hindrance of adult movie channel is the law. Under the legal regulations, there is not so much freedom for managers to run the business. In order to overcome these predicaments, they need to adopt cooperations in the industry or develop diversification to keep growing. Besides, they will face other invisible pressure such as moral pressure, the negative impression from the society and conflicts in employees' mind. Through this research, we can come out the true appearance of this special industry, and understand the way of their operation on the ecology of adult movie channel.

Abstract The main purpose of this article is to explore the policy influence of cable TV franchise combination. In order to break the local monopoly of Taiwan¡¦s cable TV as well as considering the advance technological convergence proposed, Government Information Office (GIO) proposed the adjustment of the existing 47 franchise districts to a single franchise area in three phases in its Jan. 2003 report. The re-arrangement of the franchise region will cause a revolution in the industry. How will it influence those system operators? Is it possible to develop into another cable TV war by cutting prices to gain benefits of audiences? Do system operators have any action plans for the change? Can this policy benefit the industry¡¦s development? This article will provide detailed discussions on these major issues. There are two ways to go about the research. The first is by the means of questionnaire; distribution of questionnaires to 62-system owners in Taiwan results in 54 effective samples gathered. The second is by means of in-depth interview; conducting interviews with industrial, legislative, and academic experts. After statistical analysis and content analysis, the research findings from these interviews are as follow: 1. The re-arrangement of cable TV franchise regions might cause significant competition between system operators. In the long run, it is unlikely that the cable TV industries will apply vicious competition tactics as previously done. It is believed that strategic alliance, stock exchange, and multiple service strategies will be implemented instead. 2. Under the influence of re-arranging franchise region policy and increasing new entry competitions, most system operators will focus on strengthening their network upgrade, customer service, and professional employee training. They are also likely to develop new business opportunities and to engage in cost-saving activities. 3. Most system operators support the policy with positive anticipation. The regulatory authority expects tremendous benefits for both audiences and cable industry. The scholars project an improvement in operators¡¦ customer service quality. In summary, the policy is expected to have a positive influence on cable industry¡¦s overall development. Since the policy has a major impact on the industry¡¦s future, it is essential to meet all development needs of the cable industry. As research suggests that the authorities should communicate with all related parties before rolling out the franchise regional adjustment policy.

Those mass medium, the breakthrough of the Asymmetric Digital Subscriber Line (ADSL) communication technology, and the global entertainment industries`s forwards the reconstructive changes of the competition markets, the cable TV, Fiber-Optic Technology and Air TV and so on, gradually go forwards the developments of digitalizing broadband. The Chinese Telecom MOD Service joins the cable TV competition market, resulting from the tendency cognition and the plot of telecommunication overall strategy. The MOD`s epochal pattern, the core ability, and market grasping, obviously make the cable TV system industries bear the competition pressure. This research by means of the enterprise competition "the strategy", from the industrial scope, the industrial characteristic, the element of the key will make it, the industry future and so on , carries on the discussion pointing out cable TV system in accordance to the MOD cross industry competition, how could it use the limited resources ,and well apply the market adventages to make the best adjustment for the administrative strategy. The strategy is a way to earn quite more profits. The form of the strategy depend upon apply some behavior patterns different from the competitors. By choosing the pattern which set of clear differentiable separates creates the unique valuable leading status for the enterprise. This research adapts the materialized research techniques, taking adventage of the literature analysis, depth interview and the coup-theory construction, to carries on the gleaning analysis, reorganizing the cable TV to the MOD competition in accordance to the strategy. The memoirs discovered that, In accordance to technical media flows with the conformity tendency, the Chunghwa telecommunication in order to hold the telecommunication main overman superiority, takes great efforts on enhancing the competition barriers, increasing user density, promoting management synthesis achievements. The MOD commercial localization is a link of the digital data service added the value. Through the MOD to extend the broadband IP network, the ADSL technology, may expand the enterprise network attachment value. The consideration of Air digital TV, platform opportunity, does not get rid of the correlation content provider establishing strategy cooperation relations. The Cable TV in accordance to the most effective diligently direction have three: The service conformity cuts into customer's demand, reinspect the price competition in the strategy importance, strategy competition emphasis each has its strong points and so on. The cable TV popular rate reaches most likely 85%.The consumers have accustomed to the program contents. To command the advantages of the high popular rate faces the cross industry competition. At present, we must make the signal quality stable, the service rapid, more the validity and diffusibility, in order to reestablish the reception of TV household to the system confidence. We simultaneously may use in the place media characteristic, the penetration self-restraint frequency channel influence and the customer increase interaction, the faith, and user density.
