Teraohm on-chip resistance realisation using switched capacitor topologies

Li, W.; Wang, T.; Cao, J.; Temes, G. C. (The Institution of Engineering and Technology, 2012-05-24)

Two large-resistance realisation schemes are proposed using switched-capacitor circuits. The equivalent resistance of the array realisation increases as the third power of the number of capacitor pairs, and that of th ...
A Third-Order DT ΔΣ Modulator Using Noise-Shaped Bi-directional Single-Slope Quantizer

Maghari, Nima; Moon, Un-Ku (IEEE-Institute of Electrical and Electronics Engineers, 2011-12)

This paper describes a new analog-to-digital converter based on the traditional dual-slope ADC operation. With a small modification to the discharging phase of the dual-slope ADC, first-order quantization noise shaping i ...
Tracking website data-collection and privacy practices with the iWatch Web Crawler

Jensen, Carlos; Sarkar, Chandan; Jensen, Christian; Potts, Colin (Symposium on Usable Privacy and Security (SOUPS 2007), 2007-07-18)

In this paper we introduce the iWatch web crawler, a tool designed to catalogue and analyze online data practices and the use of privacy related indicators and technologies. Our goal in developing iWatch was to make poss ...
Training conditional random fields via gradient tree boosting

Dietterich, Thomas Glen; Ashenfelter, Adam J.; Bulatov, Yaroslav (2004)

Conditional Random Fields (CRFs; Lafferty, McCallum, & Pereira, 2001) provide a flexible and powerful model for learning to assign labels to elements of sequences in such applications as part-of-speech tagging, text-to ...
Transparent p-type conducting BaCu₂S₂ films

Park, Sangmoon; Keszler, Douglas A.; Valencia, Melinda M.; Hoffman, Randy L.; Bender, Jeffrey P.; Wager, John F. (American Institute of Physics, 2002-01-10)

p-type conducting films of α- BaCu₂S₂ have been deposited onto glass and KBr substrates, yielding a conductivity of 17 S/cm and a Hall mobility of 3.5 cm²/Vs. For a 430-nm-thick film, the optical transparency approaches ...
Uplink Performance Characterization and Analysis of Two-Tier Femtocell Networks

Chakchouk, Nessrine; Hamdaoui, Bechir (IEEE-Institute of Electrical and Electronics Engineers, 2012-11)

This paper provides a cross-layer analysis of uplink performance in femtocell networks. It characterizes the uplink physical interference in femtocell networks and studies its impact on the delay and data loss rate of c ...
Vacuum ultraviolet reflectivity measurements of thin-film electroluminescent phosphors

Lite, K.; Thuemler, R. L.; Plant, T. K.; Wager, J. F.; Morton, D. C.; Sun, S. S.; Mauch, R. H. (American Institute of Physics, 1996-12-02)

Vacuum ultraviolet reflectivity measurements of three thin-film electroluminescent phosphors, zinc sulfide (ZnS), strontium sulfide (SrS), and strontium-calcium thiogallate (Sr₀.₄₅Ca₀.₅₅Ga₂S₄), are reported using thin-fi ...
A Visual Language for Explaining Probabilistic Reasoning

Erwig, Martin; Walkingshaw, Eric (Elsevier, 2013-04)

We present an explanation-oriented, domain-specific, visual language for explaining probabilistic reasoning. Explanation-oriented programming is a new paradigm that shifts the focus of programming from the computation ...
ZnO-based transparent thin-film transistors

Hoffman, R. L.; Norris, Benjamin J.; Wager, J. F. (American Institute of Physics, 2003-02-03)

Highly transparent ZnO-based thin-film transistors (TFTs) are fabricated with optical transmission (including substrate) of ~75% in the visible portion of the electromagnetic spectrum. Current–voltage measurements indica ...
