The case of Eldred v. Ashcroft focused the public’s attention on the question of the duration of a copyright owner’s right. An even more compelling problem is raised by the scope of the property right associated with copyright. Statutorily, the copyright owner is granted the exclusive rights of reproduction, distribution, adaptation, public performance, and public display subject to the doctrin...

BACKGROUND Highlighted text in the Internet (i.e., hypertext) is predominantly blue and underlined. The perceptibility of these hypertext characteristics was heavily questioned by applied research and empirical tests resulted in inconclusive results. The ability to recognize blue text in foveal and parafoveal vision was identified as potentially constrained by the low number of foveally centere...

This letter investigates the uplink outage performance of intelligent reflecting surface (IRS)-assisted non-orthogonal multiple access (NOMA). We consider general case where all users have both direct and reflection links, links undergo Nakagami-m fading. approximate received powers NOMA as Gamma random variables via moments matching. allows for tractable expressions under interference cancella...

Design issues, dynamic modeling, trajectory planning, and feedback control problems are presented for robot manipulators having components with mechanical flexibility, either concentrated at the joints or distributed along the links. The chapter is divided accordingly in two main parts. Similarities or differences between the two types of flexibility are pointed out wherever appropriate. For ro...

Robots today have an ever growing niche. Many of today’s robots are required to perform tasks which demand high level of accuracy in end effector positioning. The links of the robot connecting the joints are large, rigid, and heavy. These manipulators are designed with links, which are sufficiently stiff for structural deflection to be negligible during normal operation. Also, heavy links utili...

Understanding the users' interest is the base for the industralization of website. In order to provide individualized service better for the users, on the basis of analyzing the users' browse behavioral characteristics and according to the users' retention time in the page, and users' click frequency to the hyperlink and page, a model of computer user interest degree is established, and a neutr...

Arrays of nanoscale apertures on thin (~ 60 nm) silicon nitride membranes have been discovered to exhibit the characteristic signatures of so-called Josephson weak links in superfluid helium-4 (4He) [1]. These devices can be used to detect quantum phase differences in a matter wave interferometer made with two weak-links in a loop [2]. We summarize here our recent [3] observation of quantum int...

Many real-world domains are relational in nature, consisting of a set of entities linked to each other in complex ways. Two important tasks in such data are predicting entity labels and links between entities. We present a flexible framework that builds on (conditional) Markov networks and successfully addresses both tasks by capturing complex dependencies in the data. These models can compactl...

This paper presents two-time scale dynamic models of a high speed, lightweight parallel manipulator modeled with structural flexibility of its links. Connected by multiple closed loop chains, the platform of the parallel manipulator exhibit complex dynamic motions. Moreover, flexible deformation of lightweight links could propagate vibration to the platform in high-speed operation, that make it...
