Convective activity occurs more commonly and frequently across the United States during the spring and summer (nominally, the period of May through September). While distribution of the activity has been examined both temporally (time of maximum activity and severity) and spatially (e.g., nationally as well as regional variations) to depict its characteristic time of occurrence and pattern, ver...

In European Robins, Erithacus rubecula, the magnetic compass is lateralized in favor of the right eye/left hemisphere of the brain. This lateralization develops during the first winter and initially shows a great plasticity. During the first spring migration, it can be temporarily removed by covering the right eye. In the present paper, we used the migratory orientation of robins to analyze the...

Title of Document: THE HYDROLOGIC AND WATER QUALITY PERFORMANCE OF THE SLIGO-DENNIS BIORETENTION CELL. Jennifer M. Olszewski, Master of Science, 2010 Directed By: Professor Allen P. Davis Civil and Environmental Engineering Bioretention cells have been found to improve the hydrologic and water quality performance of impervious areas such as parking lots. The current study recorded hydrologic da...

Commercially available prosthetic hands are simple grippers with one or two degrees of freedom; these pinch type devices have two rigid fingers in opposition to a rigid thumb. This paper focuses on an innovative approach for the design of a myoelectric prosthetic hand. The new prosthesis features underactuated mechanisms in order to achieve a natural grasping behavior and a good distribution of...

This report makes a case for the need to examine the methodological foundations of AI. Many aspects of AI have not yet developed to a point of general agreement. The goals of AI work, the methods for acheiving these goals, the presentation of results, and the assessment of claims are all highly contentious issues. All aspects of AI methodology are subject to debate The Workshop on the Foundatio...

Problem 1. Infinite Products and Coproducts in Ab. We have seen that finite products and coproducts agree in Ab. However, the same is not true for infinite products and coproducts. Let I be a set and let {Ai}i∈I be a family of abelian groups, each equal to some fixed group A. (a) Show that the set AI := HomSet(I, A) is an abelian group. Furthermore, show that we can think of this group as the i...

Abstract: It is difficult to weigh the light objects by weighing balance accurately when measured individually. If several light objects are weighed in groups rather than individually then the precision of the estimates increases quite considerably. There are two types of balances one is chemical balance and other is spring balance. Spring balance is similar when only one pan of chemical balanc...

We would like to welcome our readers to the twenty-eighth issue of 49 th Parallel and our second of 2012. In the last few months there have been some exciting developments at the journal and we hope that 49 th Parallel will continue to flourish in the future. We would like to welcome our new Articles Editor, Galateia Demetriou, to the 49 th Parallel team. Galateia is a second year doctoral rese...

THE RESPONSE of hitherto known practical forms of seismographs depends upon the relative motion of a pendulum and the moving ground to which ~ts supporting structure is fastened. The various kinds of seismographs differ in the type of pendulum used, such as gravity, spring, torsion, and/or they differ in the type of magnifying and recording elements which they employ. They all measure or indica...
