The Michigan Recreational Angling Demand Model

Creator:: Lupi, Frank, Hoehn, John P., Chen, Heng Zhang, and Tomasi, Theodore D.
Abstract:: The paper reports on a large-scale demand model for recreational fishing in Michigan. The model is based on the travel cost method and is specified as a four-level nested-logit. Seasonal participation is modeled by repeating the site choice logit over the course of a season. Data on anglers' trips and...

Hue constrained matrix optimization for preferred color reproduction

Creator:: Zhang, Heng, Liu, Huaping, and Quan, Shuxue
Abstract:: A method for preferred color reproduction with a psychophysical study based upon a real-life scene demonstrated application is presented. A color correction matrix optimization algorithm is first introduced which applies additional hue constraints on top of the CIE delta E magnitude error to emphasize the importance of hue in the...

Continuous precipitation of ceria nanoparticles from a continuous flow micromixer

Creator:: Tseng, Chih Heng T., Paul, Brian K., Chang, Chih-Hung, and Engelhard, Mark H.
Abstract:: Cerium oxide nanoparticles were continuously precipitated from a solution of cerium(III) nitrate and ammonium hydroxide using a static microchannel T-mixer. Tmixer synthesis results were compared with synthesis results from batch precipitation. Findings show that the method of mixing is important in the ceria precipitation process. Uniform porous film structures and...

Laboratory experiments on counter-propagating collisions of solitary waves. Part 2. Flow field

Creator:: Chen, Yongshuai, Zhang, Eugene, and Yeh, Harry
Abstract:: In the companion paper (Chen & Yeh, J. Fluid Mech., vol. 749, 2014, pp. 577–596), collisions of counter-propagating solitary waves were studied experimentally by analysing the measured water-surface variations. Here we study the flow fields associated with the collisions. With the resolved velocity data obtained in the laboratory, the flow...

Estimating Diagnostic Accuracy of Raters Without a Gold Standard by Exploiting a Group of Experts

Creator:: Zhang, Bo, Chen, Zhen, and Albert, Paul S.
Abstract:: In diagnostic medicine, estimating the diagnostic accuracy of a group of raters or medical tests relative to the gold standard is often the primary goal. When a gold standard is absent, latent class models where the unknown gold standard test is treated as a latent variable are often used. However,...

An Impact and Management Study of Taiwanese Artificial Reef Deployment

Creator:: Chuang, Ching-Ta, Guinea, Estuardo, and Kuo, Heng Hung
Abstract:: For the past decades, around 20% of the natural coral reefs were lost and > 20% more is currently deteriorating. Due to the recognition of positive impact to fishery resources enhancement by artificial reefs (ARs) deployment, Taiwanese government has started deploying ARs as a measure to improve the environment of...

An efficient technique for excess loop delay compensation in continuous-time ΔΣ modulators

Creator:: Zhang, Y., Chen, C. H., and Temes, G. C.
Abstract:: A highly-digital technique is proposed for excess loop delay (ELD) compensation in multi-bit continuous-time ΔΣ modulators. A digitally controlled reference switching matrix is used to replace the power-hungry signal adder and extra DAC driving the quantizer, which are commonly used in ELD compensation. With the proposed technique, the feedback DAC...

Time-varying vector field design on surfaces

Creator:: Chen, Guoning, Mischaikow, Konstantin, Kwatra, Vivek, and Zhang, Eugene
Abstract:: Vector field design has a wide variety of applications in computer graphics, including texture synthesis, non-photorealistic rendering, fluid and crowd simulation, and shape deformation. This paper addresses the problem of the design of time-varying vector fields on surfaces. The additional time dimension poses a number of unique challenges to the...

Noise-Shaping SAR ADC Using Three Capacitors

Creator:: Chen, C.-H., Zhang, Y., Ceballos, J. L., and Temes, G. C.
Abstract:: In this letter, a simple and highly efficient successive-approximation Registers (SAR) ADC realization is proposed. It requires an op-amp, a comparator and only three equal-valued capacitors. The proposed scheme is insensitive to the capacitor parasitics, and has a small capacitance spread. With an oversampled scheme, it also allows noise-shaping the...

Effective doping of low energy ions into superfluid helium droplets

Creator:: Zhang, Jie, Chen, Lei, Freund, William M., and Kong, Wei
Abstract:: We report a facile method of doping cations from an electrospray ionization (ESI) source into superfluid helium droplets. By decelerating and stopping the ion pulse of reserpine and substance P from an ESI source in the path of the droplet beam, about 10⁴ ion-doped droplets (one ion per droplet) can...
