Evaluating the practicality, economic, and sampling efficiency of potential monitoring programs is a first step in validation. Thus, we established a system of nest boxes in southeast Ohio to evaluate the feasibility of using a system of nest boxes to monitor changes in southern flying squirrel (Glaucomys volans) populations. We recorded the time of box placement until first usage and types of ...

A new method for calculating fractal dimension is developed in this paper. The method is based on the box dimension concept; however, it involves direct estimation of a suboptimal covering of the data set of interest. By finding a suboptimal cover, this method is better able to estimate the required number of covering elements for a given cover size than is the standard box counting algorithm. ...

Gaussian convolution is of fundamental importance in linear scale-space theory and in numerous applications. We introduce iterated extended box filtering as an efficient and highly accurate way to compute Gaussian convolution. Extended box filtering approximates a continuous box filter of arbitrary non-integer standard deviation. It provides a much better approximation to Gaussian convolution t...

In a box-drawing of a rooted tree, each node is drawn by a rectangular box of prescribed size, no two boxes overlap each other, all boxes corresponding to siblings of the tree have the same x-coordinate at their left sides, and a parent node is drawn at a given distance apart from its first child. A box drawing of a tree is compact if it attains the minimum possible rectangular area enclosing t...

the increasing demand for rice in ghana has been a major concern to the government and other stakeholders. recent concerns by the coalition for african rice development (card) to double rice production within ten years in sub-saharan countries have triggered the to implement strategies to boost rice production in the government. to fulfill this requirement, there is a need to monitor and foreca...

background: determining the temporal variation and forecasting the incidence of smear positive tuberculosis (tb) can play an important role in promoting the tb control program. its results may be used as a decision-supportive tool for planning and allocating resources. the present study forecasts the incidence of smear positive tb in iran. methods: this a longitudinal study using monthly tuberc...

Digital nets (in base 2) are the subsets of [0,1]d that contain exactly expected number points in every not-too-small dyadic box. We construct finite sets, which we call "almost nets", such box contains almost from set, but whose size is exponentially smaller than one nets. also establish a lower bound on

The low-frequency performance of a vented-box loudspeaker system is directly related ta a small number of easily measured system parameters. This system is a fourtharder (24-dB per octave cutoff) high-pass filter which can be adjusted ta have a wide variety of response characteristics. Enclosure lasses have a significant effect on system performance and should be taken into account when assessi...

Near-field scan on a Huygens’ box can be used in order to predict the maximal radiated emission from a Printed Circuit Board. The significance of step size and phase accuracy, and the importance of a full Huygens’ box are investigated by simulation of two different models with two different numerical methods. The prediction of maximal radiated emission is quite robust but the results also show ...
