The South Pole Telescope Summertime Line Intensity Mapper (SPT-SLIM) is a pathfinder experiment that will demonstrate the use of on-chip filter-bank spectrometers for mm-wave line intensity mapping (LIM). SPT-SLIM focal plane consists 18 dual-polarization R=300 covering 120-180 GHz, coupled to aluminum kinetic inductance detectors. A compact cryostat holds detectors at 100 mK and performs obser...

We investigate line drawings as an alternative method to train an object detector. While traditional approaches rely on learning an object class from example images, we make use of abstraction provided by the artist. Our object class of choice are cats, posing a challenging detection problem by a variety of poses and appearances. In order to deal with this flexibility, and similar to part-based...

This paper discusses a mixed method that combines unsupervised learning methods and human expert input for analyzing telemetry data from long-duration robotic space missions. Our goal is to develop more automated methods for detecting anomalies in time series data. Once anomalies are identified using unsupervised learning methods we use feature selection methods followed by expert input to deri...

We are developing focal plane arrays of bolometric detectors for sub-millimeter and millimeter-wave astrophysics. We propose a flexible array architecture using arrays of slot antennae coupled via low-loss superconducting Nb transmission line to microstrip filters and antenna-coupled bolometers. By combining imaging and filtering functions with transmission line, we are able to realize unique s...

A beam profile monitor based on the use of carbon fibres is described. It has been designed to be compatible with the operation of the Mark II particle detector at the SLC, I including high resolution secondary vertex detectors mounted 25 mm radially from the beam. f Thin wire or fibre probes are in use at many accelerators to allow the measurement of beam profiles and positions [l]. In particu...

A common way of speeding up powder diffraction measurements is the use of one- or two-dimensional detectors. This usually goes hand in hand with worse resolution and asymmetric peak profiles. In this work the influence of a straight linear detector on the resolution function in the Bragg-Brentano focusing geometry is discussed. Because of the straight nature of most modern detectors geometrical...

The TWINS project (Two Wide-angle Imaging Neutral-atom Spectrometers) is mainly devoted to measure high energy neutral atoms (ENAs) originating via charge exchange of protons with geocoronal hydrogen atoms in the plasmasphere and magnetosphere. In order to unfold the local ion density along the line-of-sight (LOS) from the integrated ENA flux measurements, a good knowledge of the geocoronal hyd...

Fire presents almost everyday occurrence in people's life and work. The fight against fire must be fast effective because consequences can inconceivable, the sense of human lives material properties. occur everywhere: residential building, factory, hospital, parking garage, market, school, anywhere where are people their activities. also as natural disaster. One ways how to is detect at early s...

Images from dual detector positron emission mammography (PEM) systems are commonly reconstructed by backprojection methods of classical tomography. Characteristics of 3–D PEM images were investigated using analytic models and computer simulations, in particular depth resolution and the quality of images in the third dimension normal to the detectors. These modeling tools provide insight into th...

The Oriented Scintillation Spectrometer Experiment (OSSE) on the Arthur Holly Compton Gamma Ray Observatory satellite uses four actively-shielded NaI(Tl)-CsI(Na) phoswich detectors to provide gamma-ray line and continuum detection capability in the 0:05 ? 10 MeV energy range. The instrument includes secondary capabilities for gamma-ray and neutron detection between 10 and 250 MeV. The detectors...
