Dynamic power management: from portable devices to high performance computing

Electronic applications are nowadays converging under the umbrella of the cloud computing vision. The future ecosystem of information and communication technology is going to integrate clouds of portable clients and embedded devices exchanging information, through the internet layer, with processing clusters of servers, data-centers and high performance computing systems. Even thus the whole society is waiting to embrace this revolution, there is a backside of the story. Portable devices require battery to work far from the power plugs and their storage capacity does not scale as the increasing power requirement does. At the other end processing clusters, such as data-centers and server farms, are build upon the integration of thousands multiprocessors. For each of them during the last decade the technology scaling has produced a dramatic increase in power density with significant spatial and temporal variability. This leads to power and temperature hot-spots, which may cause non-uniform ageing and accelerated chip failure. Nonetheless all the heat removed from the silicon translates in high cooling costs. Moreover trend in ICT carbon footprint shows that run-time power consumption of the all spectrum of devices accounts for a significant slice of entire world carbon emissions. This thesis work embrace the full ICT ecosystem and dynamic power consumption concerns by describing a set of new and promising system levels resource management techniques to reduce the power consumption and related issues for two corner cases: Mobile Devices and High Performance Computing

An Analysis of Patent System and Antitrust Law Issues in OLED Display Industry: Focusing on the Patent Strategy for Securing Technologies and Materials

This dissertation presents an analysis of patent system and antitrust law issue in OLED (Organic Light Emitting Diode) display industry focusing on the patent strategy for securing technologies and materials. Material patent holders of multinational companies wielding great market power in OLED industry have pursued a variety of strategic patenting including combination inventions and broadly claimed inventions to maintain their competitive position by extension of the market exclusively beyond the legitimate scope initially granted by the patent within the current regulatory framework. Recently, their questionable patents have been challenged through patent invalidation trials brought by prospective infringers, claiming that the strategic patenting may block competitors’ exploitation of its own invention, and thus inhibit competitors’ entry. Virtually, the dominant firms’ such anticompetitive conducts have triggered antitrust scrutiny as predatory innovation and patent misuse concerns by preventing free competition between material competitors and panel manufactures in OLED industry, thereby adversely affecting consumer’s welfare to enjoy high quality and cheap products. To achieve ultimate common goal of patent law and antitrust law, this dissertation discusses: how to establish uniform and effective patent system to differentiate true improved invention from predatory innovation; and how to discourage anticompetitive predatory innovation and patent disputes in OLED industry. This dissertation is the research on the new attempt of application of US Antitrust Law to predatory innovation found in OLED industry and reinforcement of antitrust regulatory influence on the patent system

Ubiquitous computing and natural interfaces for environmental information

Dissertação apresentada na Faculdade de Ciências e Tecnologia da Universidade Nova de Lisboa para obtenção do Grau de Mestre em Engenharia do Ambiente, perfil Gestão e Sistemas AmbientaisThe next computing revolution‘s objective is to embed every street, building, room and object with computational power. Ubiquitous computing (ubicomp) will allow every object to receive and transmit information, sense its surroundings and act accordingly, be located from anywhere in the world, connect every person. Everyone will have the possibility to access information, despite their age, computer knowledge, literacy or physical impairment. It will impact the world in a profound way, empowering mankind, improving the environment, but will also create new challenges that our society, economy, health and global environment will have to overcome. Negative impacts have to be identified and dealt with in advance. Despite these concerns, environmental studies have been mostly absent from discussions on the new paradigm. This thesis seeks to examine ubiquitous computing, its technological emergence, raise awareness towards future impacts and explore the design of new interfaces and rich interaction modes. Environmental information is approached as an area which may greatly benefit from ubicomp as a way to gather, treat and disseminate it, simultaneously complying with the Aarhus convention. In an educational context, new media are poised to revolutionize the way we perceive, learn and interact with environmental information. cUbiq is presented as a natural interface to access that information
