This paper presents an effective method for computing Standard bases for the local ring of an algebroid branch and for its module of Kähler differentials. This allows us to determine the semigroup of values of the ring and the values of its Kähler differentials, which in the case of complex analytic branches are, respectively, important topological and analytical invariants. c © 2006 Elsevier L...

Introduction Mentoring is an increasingly popular concept of learning, development and support. Over the last 20, its use has grown significantly and is continuing to develop within a wide range of settings. In fact 87% of businesses in the US utilized mentoring according to a SHRM Survey (1999), (Klasen and Clutterbuck 2002). Apparently, this trend is consistent throughout other parts of the w...

We propose a new effective method for obtaining lower bounds on the number of repetition-free words over a finite alphabet.

We study extensive form games where players might not be able to foresee the possible consequences of their actions and try to exploit the opponents’ believed weaknesses in order to improve upon the final outcome. We build upon existing models of games with limited foresight, endowing players with the ability of higher-order reasoning, and proposing a novel solution concept to address intuition...

As an innovative and cost-effective method for carrying out multiple-axis CNC machining, 3 1 2 1 2 -axis CNC machining technique adds an automatic indexing/rotary table with two additional discrete rotations to a regular 3-axis CNC machine, to improve its ability and efficiency for machining complex sculptured parts. In this work, a new tool path generation method to automatically subdivide a c...

We address the problem of transferring skills learned from interactive demonstrations. Learning from Demonstration is an effective method for quickly learning to complete a task; however, task demonstrations are often provided within a particular environment, and thus cannot be immediately repeated in unfamiliar environments that differ in object configurations and features. We describe our ong...

This paper proposes an effective method for automatic melody extraction in polyphonic music, especially vocal melody songs. The method is based on subharmonic summation spectrum and harmonic structure tracking strategy. Performance of the method is evaluated using the LabROSA database 1 . The pitch extraction accuracy of our method is 82.2% on the whole database, while 79.4% on the vocal part.

In this paper, we investigate how topic dynamics during the course of an interaction correlate with the power differences between its participants. We perform this study on the US presidential debates and show that a candidate’s power, modeled after their poll scores, affects how often he/she attempts to shift topics and whether he/she succeeds. We ensure the validity of topic shifts by confirm...

Online education has become popular as an effective method of imparting knowledge to a wide audience efficiently and at low cost. Unlike traditional ”offline” courses, online courses open up the possibility of fine-grained tracking and monitoring of students’ activities, progress and performance. In turn, this creates the possibility of of analyzing the factors involved in student success, rete...

The behavior composition problem involves the automatic synthesis of a controller able to “realize” (i.e., implement) a desired target behavior specification by suitably coordinating a set of already available behaviors. While the problem has been thoroughly studied, one open issue has resisted a principled solution: if the target specification is not fully realizable, is there a way to realize...
