Paper Based Pressure Sensor for Green Electronics

This work reports a resistive paper-based disposable pressure sensor based on porous 3D conductive cellulose micro-fiber network. The conductivity in microfibers was achieved by subjecting the network to graphene oxide (GO) - poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT: PSS) solution. The modified cellulose matrix is sandwiched between graphite paper electrodes so that overall structure is flexible. The device tested in 32-386 Pa range detected a minimum of 34 Pa and exhibited fast dynamic response (in tenths of seconds) with excellent repeatability. The proposed approach for disposable sensors is a step towards green electronics and holds promise for wide range of wearable applications

Global Production Networks and Industrial Upgrading in China: The Case in Electronics Contract Manufacturing.

The paper analyzes the networks of U.S. and Taiwan based electronics contract manufacturers in South China, today the world´s most important location for low-cost mass production in the electronics industry. Based on extensive empirical research, the paper traces the production sites, the organization of manufacturing, and the workforce policies of contract manufacturers in the region, and discusses perspectives and limits of industrial upgrading, especially with regard to the role of labor. In theoretical terms, the author attempts to integrate an analysis of "global flagship networks" with concepts of industrial sociology.

Applications of Graphene at Microwave Frequencies

In view to the epochal scenarios that nanotechnology discloses, nano-electronics has the potential to introduce a paradigm shift in electronic systems design similar to that of the transition from vacuum tubes to semiconductor devices. Since low dimensional (1D and 2D) nano-structured materials exhibit unprecedented electro-mechanical properties in a wide frequency range, including radio-frequencies (RF), microwave nano-electronics provides an enormous and yet widely undiscovered opportunity for the engineering community. Carbon nano-electronics is one of the main research routes of RF/microwave nano-electronics. In particular, graphene has shown proven results as an emblematic protagonist, and a real solution for a wide variety of microwave electronic devices and circuits. This paper introduces graphene properties in the microwave range, and presents a paradigm of novel graphene-based devices and applications in the microwave/RF frequency range

Integrating security solutions to support nanoCMOS electronics research

The UK Engineering and Physical Sciences Research Council (EPSRC) funded Meeting the Design Challenges of nanoCMOS Electronics (nanoCMOS) is developing a research infrastructure for collaborative electronics research across multiple institutions in the UK with especially strong industrial and commercial involvement. Unlike other domains, the electronics industry is driven by the necessity of protecting the intellectual property of the data, designs and software associated with next generation electronics devices and therefore requires fine-grained security. Similarly, the project also demands seamless access to large scale high performance compute resources for atomic scale device simulations and the capability to manage the hundreds of thousands of files and the metadata associated with these simulations. Within this context, the project has explored a wide range of authentication and authorization infrastructures facilitating compute resource access and providing fine-grained security over numerous distributed file stores and files. We conclude that no single security solution meets the needs of the project. This paper describes the experiences of applying X.509-based certificates and public key infrastructures, VOMS, PERMIS, Kerberos and the Internet2 Shibboleth technologies for nanoCMOS security. We outline how we are integrating these solutions to provide a complete end-end security framework meeting the demands of the nanoCMOS electronics domain

Dynamic walking with Dribbel

This paper describes the design and construction of Dribbel, a passivity-based walking robot. Dribbel has been designed and built at the Control Engineering group of the University of Twente. This paper focuses on the practical side: the design approach, construction, electronics, and software design. After a short introduction of dynamic walking, the design process, starting with simulation, is discussed

Relating visual and semantic image descriptors

This paper addresses the automatic analysis of visual content and extraction of metadata beyond pure visual descriptors. Two approaches are described: Automatic Image Annotation (AIA) and Confidence Clustering (CC). AIA attempts to automatically classify images based on two binary classifiers and is designed for the consumer electronics domain. Contrastingly, the CC approach does not attempt to assign a unique label to images but rather to organise the database based on concepts

G0^0 Electronics and Data Acquisition (Forward-Angle Measurements)

The G$^0$ parity-violation experiment at Jefferson Lab (Newport News, VA) is designed to determine the contribution of strange/anti-strange quark pairs to the intrinsic properties of the proton. In the forward-angle part of the experiment, the asymmetry in the cross section was measured for $\vec{e}p$ elastic scattering by counting the recoil protons corresponding to the two beam-helicity states. Due to the high accuracy required on the asymmetry, the G$^0$ experiment was based on a custom experimental setup with its own associated electronics and data acquisition (DAQ) system. Highly specialized time-encoding electronics provided time-of-flight spectra for each detector for each helicity state. More conventional electronics was used for monitoring (mainly FastBus). The time-encoding electronics and the DAQ system have been designed to handle events at a mean rate of 2 MHz per detector with low deadtime and to minimize helicity-correlated systematic errors. In this paper, we outline the general architecture and the main features of the electronics and the DAQ system dedicated to G$^0$ forward-angle measurements.Comment: 35 pages. 17 figures.

FDI and Innovation as Drivers of Export Behaviour: Firm-level Evidence from East Asia

This paper examines the links between ownership, innovation and exporting in electronics firms in three late industrializing East Asian countries (China, Thailand and the Philippines) drawing on recent developments in applied international trade and innovation and learning. Technology-based approaches to trade offer a plausible explanation for firm-level exporting behavior. The econometric results (using probit) confirm the importance of foreign ownership and innovation in increasing the probability of exporting in electronics. Higher levels of skills, managers' education and capital also matter in China as well as accumulated experience in Thailand. Furthermore, a technology index composed of technical functions performed by firms emerges as a more robust indicator of innovation than the R&D to sales ratio. Accordingly, technological effort in electronics in these countries mostly focuses on assimilating and using imported technologies rather than formal R&D by specialized engineers.foreign direct investment, innovation, technological capabilities, R&D, firm-level exports, electronics, East Asia, China, Thailand and the Philippines
