Parks and protected area managers use zoning to decrease interpersonal conflict between recreationists. Zoning, or segregation, of recreation-often by non-motorized and motorized activity-is designed to limit physical interaction while providing recreation opportunities to both groups. This article investigated the effectiveness of zoning to reduce recreation conflict in the Vail Pass Winter Re...

Acquisitions are often used as a way to engage in corporate venturing. The value of these ventures tends to reside in the knowledge and capabilities of the key management team members who have and maintain key inter-organizational relationships. Because their knowledge and/or relationships may be tacit and therefore difficult to transfer, retaining the key managers in the acquired organization ...

We address the kinematics of the redundant N − 1 wire-driven parallel robot, i.e. a robot with N > 3 wires connected at the same point on the platform. The redundancy allows one to increase the workspace size. But we show, both theoretically and experimentally that if the wires are not elastic, then the redundancy cannot be used to control the wire tensions. Indeed we show that whatever are the...

The global population is at a turning point. At the end of 2004, the majority of the world’s population is believed to live in countries or regions below-replacement fertility, and the earlier distinct fertility regimes, ‘developed’ and ‘developing’, are increasingly disappearing in global comparisons of fertility levels (Wilson 2001, 2004). Several aspects of this convergence towards low ferti...

Introduction: The accuracy of patient positioning plays an important role for radiotherapy tasks. Short and automated Quality Assurance (QA) programs are becoming one of the challenging tasks in Radiotherapy. The current study, investigates the accuracy of treatment couch positioning with four degrees of freedom (4DoF) using a fast and accurate method based on an image acquired...

The graying of America is one of the most significant demographic changes to the present and future of the United States (Moisey & Bichis, 1999). As more baby boomers enter their 50s and 60s, the mature travel market becomes a fast-growing market segment and starts to attract attention from many tourism researchers and professionals. The significant increases in size and wealth of the older pop...

The paper covers state of the art and latest development of piezoelectric motors at Kaunas University of Technology (Lithuania), that are related to the R&D of laser scanning and deflecting devices, measuring systems, nano-resolution positioning devices on the plane, various applications including teaching aids for Mechatronics studies and even “intelligent” toys. All presented motors are oneor...

In this paper, the non-linear dynamic response of rectangular atomic force microscopy in tapping mode is considered. The effect of cantilever’s geometrical parameters (e.g., cantilever length, width, thickness, tip length and the angle between the cantilever and the sample's surface in liquid environment has been studied by taking into account the interaction forces. Results indicate that the r...

The work presents original theoretical bases of the mathematical model for determination power cables system reduction coefficient matrix. matter at hand is a new and completely general which can take into consideration an arbitrary number arrangement single-core cable arranged in treefoil formation. As fact, concerned matrix takes real (full) electromagnetic impact dominates pertaining cables,...
