Futuristic Memory Device Fabrication and Design

Lin, Wei-ching 05 September 2007 (has links)
In this article, we will review some former technology of memory devices, and its related development, mechanism and trend. And the two directions will be leaded, first is a new architecture of volatile memory, SRAM (static random access memory) cell. Its peripheral components and controlling circuit, its cornel tech and mechanism will be described, include a named RITD (resonant inter-band tunneling diode) phenomenon and its application in this work, can reduce the complexity of the memory unit, and bring other sides profits. Second, an associated with other lab mate¡¦s cooperated work, a horizontal SONOS (silicon-oxide-nitride-oxide-silicon) device will be illustrated, the ONO electrons/holes trapped region will be arranged beneath the channel of this MOS (metal oxide semiconductor) like device, what is the performance and some benchmark and comparison to another vertical SONOS design and other conventional similar devices will be done, and a real device fabrication in NDL (national device laboratory) will be completed, the detailed manufacture process will be contacted in some paragraphs. And finally, I will bring some potential ideas and possible development in the following effort inside the paper, and wish such word can lead a more breakthrough and improvement in this field.

Small lattices

Heeney, Xiang Xia Huang January 2000 (has links)
This dissertation introduces triple gluing lattices and proves that a triple gluing lattice is small if the key subcomponents are small. Then attention is turned to triple gluing irreducible small lattices. The triple gluing irreducible [Special characters omitted.] lattices are introduced. The conditions which insure [Special characters omitted.] small are discovered. This dissertation also give some triple gluing irreducible small lattices by gluing [Special characters omitted.] 's. Finally, K-structured lattices are introduced. We prove that a K-structured lattice L is triple gluing irreducible if and only if [Special characters omitted.] . We prove that no 4-element antichain lies in u 1 /v1 of a K-structured small lattice. We also prove that some special lattices with 3-element antichains can not lie in u1 /v1 of a K-structured small lattice. / viii, 87 leaves, bound : ill. ; 29 cm. / Thesis (Ph.

The minimalist conception of democracy as informed by the works of Schumpeter, Riker, and Hardin.

Thomson, Patrick Alan 17 September 2007
This thesis examines what has become increasingly classified as the minimalist conception of democracy, in an effort to define the minimalist conception, evaluate the contributions of Joseph Schumpeter, William Riker, and Russell Hardin, and assesses the impact on democratic theory of grouping these and other theorists together. The idea that minimalist theory is a tradition of democratic thought which shares a common theme has been forwarded directly only once, by Adam Przeworski, and mentioned in passing by several critics, but has never been examined in depth or defined. Chapter one gives a brief survey of minimalist theorists and defines minimalist theories as those that conclude that any normative value found in substantive democratic outcomes is insufficient to justify democracy. Chapters two and three examine the works of the two most influential minimalists, Schumpeter and Riker, respectively. These chapters examine the minimalist aspects of both theorists and note that, in entirely unique manners, both reach the minimalist conclusion. Chapter four examines the relatively recent works of Hardin, noting several similarities between his theories and those of Schumpeter and Riker. Hardin is found to satisfy the definition of minimalism and make several unique contributions to minimalist theory, most notably by synthesizing Schumpeter's understanding of individual political competence with Downs's rational voter theorem. In the conclusion, chapter five, it is argued that there is merit to considering all minimalist theories as a single conception of democracy as theories that contradict the minimalist conception, as defined in chapter one, often attempt to dismiss one minimalist theorist, but ignore the others, to the detriment of their work and to democratic theory in general.

Three essays on free trade agreements and R&D collaboration: a network approach

Zhang, Jin January 2009 (has links)
This dissertation consists of three chapters. Chapter 1 and 2 apply network formation theory to the study of free trade agreements, and chapter 3 investigates R&D alliance in a network context. The first chapter considers a setting with n countries. These countries are able to negotiate bilateral free trade agreements (FTAs) to form trading networks. A new solution concept, the pairwise farsightedly stable set, is adopted to predict which free trade network may emerge among forward looking countries. The key finding of this chapter shows that the complete global free trade network is pairwise farsightedly stable. It is also shown that the complete global free trade network is the unique strongly efficient structure, maximizing the total welfare of all countries. However, the complete network is not the uniquely stable one. It coexists with other inefficient stable outcomes. This result motivates the second chapter whose purpose is to provide a non-cooperative support for the efficient complete network. The objective of the second chapter is to design an extensive form game whose subgame perfect equilibrium can generate the efficient complete network. Given an arbitrary network, proposer is chosen according to a fixed rule of order. The chosen country has options to cut one of her links, or offer a link to another country. We restrict our attention to stationary strategies and construct a stationary subgame perfect equilibrium strategy profile for this infinite-horizon game. It is shown that no matter from which network, the complete global free trade network, as the only efficient configuration, is able to be attained as a SPE outcome. The third chapter models R&D collaboration networks with asymmetric firms. The main results show that the stable network structure does not maximize the total payoffs. However, such a tension can be eliminated when domestic government is incorporated as a strategic player / Cette thèse comporte trois chapitres. Les chapitres 1 et 2 sont une application de la théorie de la formation des réseaux à l'analyse des accords de libre-échange, et le chapitre 3 examine les alliances de R&D en contexte de réseau. Le premier chapitre considère une situation comportant n pays. Ces pays sont capables de négocier des accords de libre-échange (ALE) bilatéraux pour former des réseaux commerciaux. Un nouveau concept de solution, l'ensemble par paire à stabilité prévue, est adopté afin de prédire quel réseau de libre-échange pourra émerger entre les pays prévoyants. La principale découverte dans ce chapitre est de démontrer que le réseau de libre-échange mondial est un ensemble par paire à stabilité prévue, ce qui implique que le mouvement mondial vers les ALE va continuer jusqu'à ce que le réseau complet soit atteint. Il est également démontré le réseau de libre-échange mondial complet est l'unique structure efficiente, maximisant le bien-être collectif de tous les pays. Par contre, le réseau complet n'est pas le seul qui soit stable. Il coexiste avec d'autres résultats qui sont stables et inefficients. Ce résultat motive également le second chapitre, dont l'utilité est de fournir un support non-coopératif pour le réseau complet efficient. Le but du second chapitre est de créer un jeu dynamique pour lequel l'équilibre parfait en sous-jeu peut générer un réseau complet efficient. Étant donné un réseau arbitraire, le proposant est choisi selon une règle d'ordre fixe. Le pays choisi a l'option de couper l'un de ses liens, ou d'offrir un lien à un autre pays. Nous restreignons notre attention aux stratégies stationnaires et construisons un profil de stratégie d'équilibre parfait du sous-jeu stationnaire pour ce jeu à horizon infini. Il est démontré que peu importe de quel réseau il provient, le réseau de libre-échange mondial complet,

Secure implementation, network cost sharing and oligopolistic price discrimination

January 2010 (has links)
In chapter 1, we consider the possibility of Secure Implementation in Production Economies beyond the result provided in the Saijo et al. (2007) paper. We find a large class of SCFs to be securely implementable. The serial SCF and the widely studied Fixed Path SCFs which contains serial SCF as a special case are all special cases of our function. In chapter 2, which is a version of my work with Ruben Juarez, we consider the problem of sharing the cost of a network formed by choice of paths of agents to connect their demand nodes. Motivated by the inefficiency, instability and huge informational requirements of the widely used Shapley (Sh) cost sharing rules, we look for mechanisms in a setting of minimal informational requirement which overcome the said shortcoming. We characterize a class of such mechanisms under different notions of robust implementations. We also discover that voluntary participation is possible in this setup with no more inefficiency than that of Sh. In chapter 3, which is a version of my work with Levent Kutlu, we consider the aspect of price discrimination under oligopolistic setting. The environment has two stages of the game. In first stage the firms fight on the quantity they want to put in the market and then in the second stage they decide how to distribute that quantity among the buyers with different valuations. We characterize the unique NE of this game. The firms which ends up with higher quantity in the first stage sells to all the buyers whereas the smaller firm sells some of the high end buyers.

Veblen on medicine: a sociological analysis of the cultural and organizational development of medicine as a social institution

Hille, Kathy 15 May 2009 (has links)
The focus of this dissertation is to provide a cultural and organizational analysis of the development of medicine as viewed through the theoretical tenets of Thorstein Veblen, one of our most brilliant social and economic theorists. I trace the historical development, examine the current status, and project the future trends of our medical institution. I explore how our current medical system has evolved, both culturally and organizationally, along the same path that Veblen set forth in his social and economic theories of instincts, status emulation, ceremonial-technological dichotomy, and business and market capitalism. I include his thoughts on the development of institutions and the ways in which cultural lag impedes progress. To accomplish this, I rely heavily on theoretical discussion, interpretative analysis of secondary data, and qualitative analysis of current medical issues. As a result, I discover that the development of medicine as a social institution has followed a predictable course; one that reflects a cultural and organizational dilemma created by the profit motive, which restricts the implementation of technological advances and negatively impacts the health of our nation. I find that the ability to view a modern day social institution, such as medicine, through the lens of theories that were at the forefront of social and economic thought at the beginning of the twentieth century, provides us with a unique perspective; the insight to better understand exactly why that development occurred. With that understanding, we are better equipped to alter future development thereby improving structures, processes, policies, and procedures. This research focuses on exposing not only how the institution of medicine evolved but, more importantly, what we can do to improve the delivery of health care and the overall health of our nation’s population.

New Skyrme nucleon-nucleon interaction for the mean-field approximation

Vuong, Au Kim 17 September 2007 (has links)
The effective Skyrme type interactions have been used in the mean-field models for several decades, and many different parameterizations of the interaction have been realized to better reproduce nuclear masses, radii, and various other data. Today, there are more experimental data of nuclei far from the B stability line. It is time to improve the prediction power of the Skyrme type effective nucleon-nucleon interactions. In this dissertation, we present the procedure of the fitting of the mean-field results to an extensive set of experimental data with some constraints on the Skyrme parameters and some approximations in the Hartree-Fock mean-field to obtain the parameters of the new Skyrme type effective interactions, namely, KDE and KDE0. We investigate the long-standing discrepancy of more than 20% between the values of the incompressibility coefficient Kn:m: obtained within relativistic and non-relativistic models. We show that this difference is basically due to the differences in values of the symmetry energy coefficient J and its slope L associated with the relativistic and non-relativistic models. We also present the results of fully self-consistent Hartree-Fock based Random Phase Approximation calculations for the centroid energies of the breathing modes in four nuclei, namely, 90Zr, 116Sn, 144Sm, 208Pb, obtained with our new Skyrme interaction KDE0. A good agreement with the experimental data is achieved.
