We continue our study of document marking to deter illicit dissemination. An experiment we performed reveals that the distortion on the photocopy of a document is very diierent in the vertical and horizontal directions. This leads to the strategy that marks a text line both vertically using line shifting and horizontally using word shifting. A line that is marked is always accompanied by two un...

In [k]n = [k]×[k]× · · ·×[k], a line consists of the collection of points where all but one coordinate is fixed and the unfixed coordinate varies over all possibilities. We consider the problem of marking (or designating) one point on each line in [k]n so that each point in [k]n is marked either a or b times, for some fixed a or b. This is equivalent to forming a strategy for a hat guessing gam...

Three experiments examined connections between old/new item recognition and memory for temporal order information. With series of compound gratings as study and probe items, subjects made temporal order judgments (Experiments 1 and 2) by identifying the serial position of the study item that matched the probe, or recognition judgments (Experiment 3) by judging whether the probe had or had not b...

The database used by Hemmingsen (1960) to compute energy metabolism in unicellular organisms was reassembled and submitted to linear (log-log) analysis. As Hemmingsen noted, this data set includes marine zygotes, which are not unicellular organisms. If no temperature correction factors are applied to the data the best-fit regression line has a slope of 0.698 +/- 0.024. Application of the temper...

When using a 3D deterministic model to evaluate the landslide susceptibility of regional area, processing large amounts of spatial data and identifying the objective for applying the deterministic model would be arduous works. In this research, an enhanced hydrology tool is developed to automatically identify the objectives of research, which are called slope units, from terrain raster data. A ...

OBJECTIVES In the occupational health field, it is important to know how workload influences mental health. Overtime work and job strain appear to affect the mental health status of workers. Sense of coherence (SOC) may mediate the relationship between work stress and mental health. Since SOC represents a personal ability to manage psychological stressors, we hypothesized that a strong SOC woul...
