Title: A Discriminative Semi-Markov Model for Robust Scene Text Recognition
Description: We present a semi-Markov model for recognizing scene text that integrates character and word segmentation with recognition. Using wavelet features, it requires only approximate location of the text baseline and font size; no binarization or prior word segmentation is necessary. Our system is aided by a lexicon, yet it also allows non-lexicon words. To facilitate inference with a large lexicon, we use an approximate Viterbi beam search. Our system performs robustly on low-resolution images of signs containing text in fonts atypical of documents.

Title: A Simple Experiment for Discussion of Quantum Interference and Which-Way Measurement
Description: Motivated by a recent experiment involving which-way measurement in atom interference, we developed a completely analogous experiment using visible light. This simple experiment, easily accessible to undergraduate students and the resources of undergraduate departments, facilitates examination of the key elements of which-way measurement, quantum erasure and related mysteries of quantum measurement. The experiment utilizes a Mach-Zehnder interferometer, and visually demonstrates the loss of interference fringes when a which-way measurement is imposed, and the restoration of that pattern when the which-way information is destroyed. This device is also sensitive enough to observe interference fringes arising from single photons. At a level accessible to undergraduates, we present simple analyses of the interference appropriate for the coherent classical field limit, and the single photon limit. We briefly mention related issues of the nature of the photon, pointing to some useful references.

Title: A Two-Sector Effort-Regulation Model with Implications for Wage Developments of the 1980s
Description: A simple two-sector effort-regulation model, which assumes that the cost of job loss responds to labor's bargaining power and which acknowledges influences of institutional change, import penetration and shifting employment, can account for the declining real wages for non-supervisory workers in goods sector industries in the 1980s.
