In order to test the ability of the Internet to supplement classroom instruction, an instructor-authored WWW site crashwhite.com was developed for two Berkeley High courses: Advanced Placement (AP) physics, and college-prep physics class. The website was intended to supplement classroom instruction by making classroom materials available to students and parents outside the classroom, and to facilitate increased teacher-parent, teacher-student, and student-student communication.

In modern networks, the increasing volume of network traffic and the diverse range of services with varying requirements necessitate the implementation of more advanced routing decisions and traffic engineering. This academic study proposes a QoS adaptive mechanism called "Sepitto", which utilizes Segment routing protocols, specifically SRv6, to address network-traffic control and congestion avoidance. Sepitto leverages data-plane traffic to convey Linux Qdisc statistics, such as queue size, packet drops, and buffer occupancy, in each Linux-based virtual router. By incorporating this information, edge routers become aware of the current network status, enabling them to make informed decisions regarding traffic paths based on QoS classes. SRv6 is employed to direct traffic along desired paths, avoiding congested links and minimizing queuing delays and overall latency. Moreover, Sepitto offers network administrators an interface to customize decision-making processes based on their policies, assigning costs to network graph edges by associating the provided statistics to a certain cost. To incorporate these costs, the implementation employs the Dijkstra algorithm to determine the path with the lowest cost. Performance analysis of Sepitto reveals minimal overhead compared to traditional routing methods, while effectively mitigating network congestion. The results demonstrate that Sepitto reduces traffic round-trip time during congestion while maintaining differentiated treatment for various QoS classes. / I moderna nätverk kräver den ökande volymen av nätverkstrafik och det varierade utbudet av tjänster med olika krav att mer avancerade ruttbeslut och trafikhantering implementeras. Denna akademiska studie föreslår en QoS-anpassningsmekanism kallad Sepitto", som använder sig av Segment Routing-protokoll, specifikt SRv6, för att hantera nätverkstrafik och undvika trängsel. Sepitto utnyttjar dataplanttrafik för att överföra Linux Qdisc-statistik, såsom köstorlek, paketförluster och buffertbeläggning, i varje Linux-baserad virtuell router. Genom att införliva denna information blir kantrouter medvetna om den aktuella nätverksstatusen och kan fatta informerade beslut om trafikvägar baserat på QoS-klasser. SRv6 används för att styra trafiken längs önskade vägar, undvika överbelastade länkar och minimera köfördröjningar och övergripande latens. Dessutom erbjuder Sepitto nätverksadministratörer ett gränssnitt för att anpassa beslutsprocesser baserat på deras policy, genom att tilldela kostnader till nätverksgrafens bågar genom att associera de tillhandahållna statistiken till en viss kostnad. För att införliva dessa kostnader använder implementeringen Dijkstras algoritm för att bestämma vägen med lägst kostnad. Prestandaanalysen av Sepitto visar minimal överbelastning jämfört med traditionella rutteringsmetoder samtidigt som den effektivt motverkar nätverksträngsel. Resultaten visar att Sepitto minskar trafiklatensen under trängsel samtidigt som differentierad behandling bibehålls för olika QoS-klasser.

Master of Landscape Architecture / Department of Landscape Architecture/Regional and Community Planning / Stephanie A. Rolley / College districts are unique places that often times blend the culture, history, and the future direction of a city. They are places that foster knowledge, interaction, and diversity. A successful college district enables all citizens to help shape a place that is unique amongst other districts throughout the city. They are places where people relax, work, socialize, think, revolt, and reunite. They are, perhaps, the most important districts within college towns. The intent of this project is to completely reinvent a district to be one that all citizens (permanent and student) of Ames, Iowa can utilize throughout the year. Reversing the negative perceptions of Campustown through design and programming will help recreate a district that fosters interaction among students of Iowa State University and the citizens of Ames. Further, the recreation of Campustown will benefit the community in terms of image, economics, environment, and place. Campustown will no longer be perceived as an enclave of substandard student housing, trashy bars, and a district that caters to only one group. It will be a place where people come together to celebrate Ames and ISU and to come together to meet friends and family. To enable a thorough understanding of successful college districts, two case studies were examined in great detail to help understand what makes these places work. A complete site inventory and analysis of Campustown was also conducted to help determine where and what shortcomings are present throughout the site. Several different programming elements have been selected that would be appropriate to locate in the Campustown area. And finally, a complete master plan has been created that will enable Campustown to function properly long into the future for every citizen of Ames.

Interessa saber se há, em seu pensamento, uma unidade no critério de inteligibilidade desses objetos. Busca-se, para isso, reconstruir alguns de seus argumentos quanto ao que ele considera como objetos legítimos não só da aritmética, álgebra e geometria, como também do cálculo infinitesimal. A partir disso, serão avaliadas as consequências interpretativas de seus textos de maturidade - como é o caso do texto O Analista (1734), conhecido pela crítica ao cálculo infinitesimal - sobre se há primazia de tais objetos no processo de avaliação da cientificidade das matemáticas. Não se almeja, portanto, adotar como porta de entrada a macro questão sobre o que é ciência matemática, para Berkeley, mas a questão de como a noção de objeto matemático apresenta-se, ou não, como um dos elementos importantes para o esclarecimento desse problema mais geral / Abstract: The aim of this thesis is to establish a study of how Berkeley devised mathematical objects. It is of interest to know whether there is, in his thinking, a unit in the criterion of intelligibility of these objects. To do this, we try to reconstruct some of his arguments about what he considers as legitimate objects, not only in arithmetic, algebra and geometry, but also in the infinitesimal calculus. From this, the interpretive consequences of his maturity texts are evaluated - such as the text The Analyst (1734), which is known for the criticism of the infinitesimal calculus - on whether there is primacy of such objects in the process of evaluating the scientific character of mathematics. Therefore, we don¿t want to adopt as an entrance the more general question of what is mathematical science, to Berkeley, but the question of how the notion of mathematical object is presented, or not, as one of the important elements to enlighten this more general problem / Doutorado / Filosofia / Doutor em Filosofia

La presente investigación gira en torno al problema del autoconocimiento según Berkeley, que trata de cómo el espíritu se conoce a sí mismo si no se puede percibir o tener ideas de sí mismo. El tema central es la noción del propio espíritu: ¿cuál es su proceso cognitivo y su contenido? En el primer capítulo, se discute la interpretación de Bennett acerca del tipo de entendimiento que es la noción; en el segundo, se debate la postura de Flage sobre si la noción del propio espíritu es relativa o positiva; y en el tercero, se aborda la relación entre la noción del propio espíritu finito y el conocimiento de otros espíritus, tanto del espíritu infinito (Dios) como de los otros espíritus finitos. Mi propia interpretación sobre la noción del propio espíritu es desarrollada a lo largo del trabajo, concluyendo que hay dos vías de autoconocimiento, a saber: la inferencia de la propia “existencia” en cuanto causa de las propias ideas producidas y, principalmente, la noción positiva, que consiste en una aprehensión intuitiva, directa e inmediata de la propia “esencia” en cuanto actividad perceptiva; es decir, se trata de un acto reflexivo de “presentación mental” que presenta o refleja lo que el propio espíritu es en sí mismo, a saber: la unidad total e indivisible de los propios actos de percepción, la cual es imagen (en sentido amplio) de la esencia de los otros espíritus

El presente trabajo consta de tres partes: una introducción y dos capítulos. En la introducción busco familiarizar al lector con el contexto histórico en el que se desarrollo el pensamiento de George Berkeley. En el primer capítulo, caracterizo el idealismo berkeleyano como un empirismo cartesiano. De esta forma, muestro que Locke y Descartes influyeron directamente en la filosofía de Berkeley e hicieron posible el idealismo. En el segundo capítulo, examino la supuesta incongruencia, encontrada por George Pitcher en la filosofía de Berkeley, entre las siguientes tesis: i. La mente percibe ideas. ii. La mente y sus ideas son completamente distintas. iii. Es falsa la distinción entre la percepción de una idea y la idea percibida. Del mismo modo, en el segundo capítulo evalúo el análisis de Pitcher e indico los errores del mismo. Mi ataque se centra en demostrar que este es inadecuado porque analiza (ii) y (iii) como sugiriendo que el tipo de relación entre las mentes y las ideas es modal. Expongo como este tipo de distinción cartesiana es insuficiente para establecer lo que Berkeley desea señalar respecto a ambas tesis. Finalmente, muestro porque el análisis de Pitcher genera una serie de problemas que podrían evitarse si es que (iii) fuera interpretado como sugiriendo que la existencia de una idea consiste en su ser percibida.
