In this investigation, biodegradable polycaprolactone polymeric particles (300-4500 nm in diameter) were prepared by jetting a solution in an electric field. An extensive study has been carried out to determine how the size and size distribution of the particles generated can be controlled by systematically varying the polymer concentration in solution (and thereby its viscosity and electrical ...

Measuring the functional size of software was proposed by Albrecht, more than 20 years ago, as a solution to the limitations of lines of code (SLOC) when quantifying the output of the software engineering process. While this approach has been, and still is, successful when applied to MIS type of software, it has not enjoyed the same success for measuring the size of non MIS software, as demonst...

Biologically inspired hierarchical networks for image processing are based on parallel feature extraction across the image using feature detectors that have a limited Receptive Field (RF). It is, however, unclear how large these receptive fields should be. To study this, we ran systematic tests of various receptive field sizes using the same hierarchical network. After 40 epochs of training, we...

This study focuses on improving the potential field based maritime data modeling method, developed to extract traffic patterns and detect anomalies, in a clear, understandable and informative way. The method's novelty lies in employing the concept of a potential field for AIS vessel tracking data abstraction and maritime traffic representation. Unlike the traditional maritime surveillance equip...

Individual voles were tested on successive days under increasing, decreasing, or randomly changing arena size. Locomotor behavior was adjusted to arena size by (i) preserving the same level of activity, (ii) taking longer but less frequent trips in smaller arenas in contrast to taking more frequent yet shorter trips in the larger arenas, and (iii) moving in the entire space available for explor...

In most software cost estimation models, software size is the key cost driver. Such models use either a technical measure of software size, based on lines of code, or alternatively a functional size measure which can be known earlier in the software life cycle. However, even though Function Points is the most widely used functional size measure in the MIS domain, practitioners have often pointe...

Ershkovich has recently criticized earlier arguments by Mendis for substantial magnetic fields (B"" 1001) in the cometary plasma tail. It is shown that these criticisms are unjustified. Contrary to Ershkovich's claim, it is shown that the folding rate of the tail rays is indeed indicative of a substantial tail magnetic field. Much of the disagreement stems from Ershkovich's idealization of the ...
