This quarter we primarily worked on optimizing the edge and line detectors incorporated in our image analysis software. We changed our optimization scenario and designed a metric for the evaluation procedure. With our optimized detectors, we achieved a match error rate of 29.3%, as well as a low level of insertion, on the test set 01 from the Pre-phase 01 image data. Meanwhile, we started inves...

An international network of laser-interferometric gravitational wave detectors is nearing the end of the main commissioning phase and will soon enter into an extended observational period, collecting data for a duration of order one year. This article outlines the construction, design and commissioning of the GEO 600 gravitational wave observatory. GEO 600 is a laserinterferometric gravitationa...

The application of ultraviolet absorption detector (UV) and circular dichroism (CD) detectors in series in HPLC systems has been increased in recent years. In this work, an effective method to determine the enantiomer concentration on line in chiral drugs was explored. Ibuprofen (IBP) racemate was applied. The total concentration and concentration difference of S-(+)-IBP and R-(-)-IBP were obta...

A new proposal for Cartan contortion detection based on the resonant gravitational wave (GW) detector in teleparallel spacetime is considered.It is shown that Cartan contortion is proportional to the inverse of the damping time of the resonant detector.Actually the contortion acts as a damping force for the GW.A contortion of the order 10 −29 s −1 is obtained by using the data of present resona...

We report on the manufacture of a first batch of approximately 2,000 Gas Electron Multipliers (GEMs) using 3M’s fully automated roll to roll flexible circuit production line. This process allows low-cost, reproducible fabrication of a high volume of GEMs of dimensions up to 30×30 cm. First tests indicate that the resulting GEMs have optimal properties as radiation detectors. Production techniqu...

The visual detection of robots is a difficult but relevant problem in several robotic applications. In the present article, a framework for the robust and fast visual detection of legged-robots is proposed. This framework uses cascades of nested classifiers, the Adaboost boosting algorithm, and domainpartitioning based weak classifiers. Using the proposed framework, frontal, profile and back de...

A novel and eecient generalized feature extraction method is presented based on the Expansion Matching (EXM) method and the Karhunen-Loueve (KL) transform. The EXM method is used to design optimal detectors for diierent features. The KL representation is used to deene an optimal basis for representing these EXM feature detectors with minimum truncation error. Input images are then analyzed with...
