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.

An introductory note of the talk on cosmology. Some of the text are copied from the talk by G. Lazarides, http://arxiv.org/pdf/hep-ph/9904502v2.pdf. As of the date: May 29, 2012.

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...

We study the connection between the number of ascending and descending cuts of a linear order, its classical size, and its effective complexity (how much [how little] information can be encoded into it).

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...

Under the APA (5 U.S.C. 551–553) our normal practice is to publish policies with a 30-day delay in effective date. In this case, however, we use the ‘‘good cause’’ exemption under 5 U.S.C. 553(d)(3) to make this rule effective upon publication. This rule relieves a restriction, and it is not in the public interest to delay its effective date. We believe that another nontoxic shot option likely ...

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...
