Few researchers investigating the survival to emergence of embryonic salmonids have simultaneously compared the predictive ability of the percentage of fine sediment less than a given diameter, the geometric mean particle size, and the fredle index. We quantified the relation between these different measures of suhstrate compoaition and survival to emergence of two stocks of brown trout, Salmo ...

Background In-shoe pressure measurement devices are commonly used in research and clinical settings to quantify pressure on the plantar foot. Various in-shoe pressure measurement devices are currently available and they differ in their size, number of sensors, sensor type and therefore their loading response and accuracy. Previous comparisons focus on pressure plates [1]. An in-shoe study highl...

We have developed a compact wireless modular sensor architecture, which contains a number of circuit boards (panes), currently used in an application for on-shoe gait analysis. Each pane instantiates a major function – e.g. inertial sensing, tactile sensing or data collection and transmission. As opposed to similar architectures, this system treats the sensor panes as discrete design objects th...

This paper examines the implementation of Mobile Number Portability (MNP) in Ghana and presents the experiences of subscribers with the implemented MNP policy. According to a cost-benefit analysis of the portability process, it is evident that the over 19 Million Mobile subscribers satisfy the minimum market size below which overall benefits cannot be felt. From the study, we argue that, even t...

This paper develops a sustainable yield harvesting model for the wild Atlantic salmon (Salmo salar), where the population comprises different age classes. It is shown that the weight– fecundity relationship of the spawning population, comprising young and old fish, is crucial for the maximum sustainable yield fishing composition. First, the optimal harvest is found when fecundity is approximate...

Four groups of rats were tested on an eight-arm radial maze under a free-choice procedure. The subjects were maintained at either 80% or 100% of their preexperimental free-feeding weights through restricted access to either food or water. Water-deprived subjects received water in the maze; food-deprived subjects received food. Water-deprived subjects learned the task faster than food-deprived s...

Laser footprint size and beam divergence angle tuning was found to affect LiDAR data accuracy and measurement precision because of beam axis shifting. The laser beam divergence angle is generally tunable in modern LiDAR systems in order to adapt to different application scenarios. Beam divergence angle can either be switched from one position to the other (i.e. 0.3mRad / 0.8 mRad), or be tuned ...

With the increasing spread of computers and the internet among culturally, linguistically and geographically diverse communities, issues of internationalization and localization and becoming increasingly important. For some of the issues such as different scales for length and temperature, there is a well-developed measurement theory. For others such as date formats no such theory will be possi...
