WideBand PLL as a clock multiplier
No full textIn this study, the theory, design and analysis of PLL circuits are examined and a 4.9GHz ~ 5.9GHz Wideband CMOS PLL Frequency Synthesizer is designed and implemented in IBM 65nm digital-process. The objective of this thesis work is to understand the limitations in Wideband PLL systems when the application frequency range extends to multiple gigahertz. This study explores the inband noise contribution of PLL blocks and also investigates solutions to high frequency operation of phase frequency detectors and charge pumps. A high frequency phase-frequency detector topology is presented. With this topology, static phase error of the loop remains close to zero even if the charge-pump has a large amount of current mismatch. A design which is capable correct operation up to a frequency 1.74 GHz is designed. A high frequency differential charge pump circuit with glitch suppression is presented. The VCO of the PLL is implemented with a mutlipath loop ring oscillator. The VCO has a better supply noise performance compared to conventional ring oscillators but however it is still not suitable for applications with noisy supply, thus off chip supply decoupling is used. VCO operates within 4.79GHz ~ 6.54GHz for all process corners. The frequency divider which is used from project library has a constant division ratio of 6. Entire PLL design consumes 14.9 mW from 1.2 V supply, under typical conditions. Total area of the PLL is 1 mm x 800 um including the pads.Microelectronics & Computer EngineeringElectrical Engineering, Mathematics and Computer Scienc

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Down to Earth
No full textThe first half-year we were working in a collective (9 persons) and doing a thorough research and analysis. We took the Riberas del Bravo settlement in the northern Mexican city of Ciudad Juárez as a case study. This city has numerous problems, of which the emerging phenomenon of abandoned and deserted housing in Mexico is among its most striking. The entire settlement consists of dwellings built between 2000 and present, of which about 20% - 25% are abandoned houses. This phenomenon has various reasons and points towards a complex mesh of forces that influence the built environment. They encompass entangled dimensions of political economy and socio-economic developments, which only touch the built structure of actual housing at the very last stage. In the first weeks we were investigating the events in the history of Juárez, which lead to its formation, its growth and ultimately to the problems of today. Eventually this resulted in a timeline, historical maps and analytical maps of all the (main) factors involved. In the end of the Msc-3 period our research resulted in a common strategic proposal on the level of the city and moreover on the level of the case-study. Because of all the information we gathered and the group-strategy it resulted in, I had the possibility to create a project, which is not only architectural, but also sensitive to its environment. Aspects of my project (like setting up of an alternative economic model based on Adobe production, tackling mono-functionality and long-term solutions) are a direct result of the combined effort of the collective strategy. I think because of my intuitive way of working, I have now a project which is more dynamic (a plot which transforms over the course of 50 years, through means of various aspects), from Urban plan to the very grain of an Adobe in the wall in the common kitchen. And above all, my project is now a firm stance against the social atrocities and urban asymmetries prevalent in Juárez. It is not just a design projected on a certain spot, but on the contrary: a project, which involves local inhabitants in a refined and responsible way. The project succeeds, when inhabitants take the initiative to pick up a shovel and oppose to the dependency of the Maquiladora-system (this system is proven to be destructive for Juárez). As a result an architecture emerges, which doesn’t deny the Urban Asymmetries, but embraces them and turn them into a positive social-economic experiment. An architecture, which at the same time (among others) is a repetition of a standard unit, but succeeds in not becoming a mere monotonous and mono-functional plan, but rather a diverse and sophisticated part of the settlement. My project is part of a collective work, of several projects, which together make a difference and form a prototype for the revitalization of the city of Ciudad Juárez.Urban Asymmetries, Ciudad Juárez, Mexico StudioDelft School of Design (DSD)Architectur

The Right to Strike under the United States Constitution: Theory, Practice, and Possible Implications for Canada
No full textAnswering critics of the Canadian Supreme Court's judgment in B.C. Health, the author argues that the Court laid the foundation for a principled and durable doctrine protecting constitutional labour rights, one that goes directly to the heart of the matter — the inequality of workers’ power in the employment relation. In the author’s view, two paths could lead from B.C. Health to the recognition of Charter protec- tion for a right to strike: one that treats the right as an accessory to col- lective bargaining, and one that upholds the right directly on the basis of the Charter values of equality and participation. The author supports the latter approach, contending that constitutional rights should be defined in relation to fundamental values, in a way that is not contingent on time-bound or fact-sensitive assessments about the role of strikes within a particular collective bargaining regime. Although a Charter right to strike may involve the courts in difficult choices about when to defer to legislative policy decisions, and courts may lack the institutional capac- ity to deal effectively with labour law issues, the author points out that judges can look to ILO standards for expert guidance. Noting that the U.S. experience in this area might be of considerable use to Canadians, the author concludes by providing an overview of American case law concerning a constitutional right to strike.Peer reviewe
G-Rank: Unsupervised Continuous Learn-to-Rank for Edge Devices in a P2P Network
No full textRanking algorithms in traditional search engines are powered by enormous training data sets that are meticulously engineered and curated by a centralized entity. Decentralized peer-to-peer (p2p) networks such as torrenting applications and Web3 protocols deliberately eschew centralized databases and computational architectures when designing services and features. As such, robust search-and-rank algorithms designed for such domains must be engineered specifically for decentralized networks, and must be lightweight enough to operate on consumer-grade personal devices such as a smartphone or laptop computer. We introduce G-Rank, an unsupervised ranking algorithm designed exclusively for decentralized networks. We demonstrate that accurate, relevant ranking results can be achieved in fully decentralized networks without any centralized data aggregation, feature engineering, or model training. Furthermore, we show that such results are obtainable with minimal data preprocessing and computational overhead, and can still return highly relevant results even when a user’s device is disconnected from the network. G-Rank is highly modular in design, is not limited to categorical data, and can be implemented in a variety of domains with minimal modification. The results herein show that unsupervised ranking models designed for decentralized p2p networks are not only viable, but worthy of further research.https://github.com/awrgold/G-RankComputer Scienc
