background: radon concentration was measured in 50 drinking water samples in mashhad - iran. b the tap water used for drinking and other household usages can increase the indoor radon level. drinking water samples were collected from various places and supplies of public water used in mashhad. then radon concentration has been measured by portable radon gas surveyor silena (prassi) system. resu...

In our study, bioactivity of essential oil extracted from Ginger (Zingiber officinaleRoscoe.) that belongs to family Zingiberaceae was analyzed. Ginger rhizome oil was found to be effective against a range of bio-deteriogens. The Minimum Inhibitory Concentration (MIC) value was determined by Poisoned Food Technique and Volatile Activity Assay. The study demonstrates that essential oil had a wid...

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).
