Active Learning System for iPTF Candidate Classification

The Intermediate Palomar Transient Factory (iPTF) is a visible-spectrum astronomy survey aimed at detecting “transient” events such as supernovae. Every night, a telescope at the Palomar observatory collects images of various regions of the sky and compares them to a set of reference images taken on previous nights. The image comparison is done via a subtraction process. The reference images are subtracted from the new nightly images, and any remaining light sources are flagged as candidate transient events.

Cobra: an Extendable Tool for Interactive Code Analysis

Source code analysis typically requires the use of expensive and difficult-to-configure tools that support only a predefined set of standard checks. In some cases, it is possible to add customized checks, but doing so can be laborious and requires a deep understanding of each tool’s internal data structures, which means that it is rarely done.

A 40-Year Legacy and Excitement for the Future

As I approach retirement after 40 years as CEO of National Instruments (NI), I am reminded of the great progress and innovations the test and measurement industry has witnessed over that time. We have gone from an industry driven by vacuum tube technology in the era of General Radio, to a time where the transistor ruled with Hewlett-Packard, to today where software truly is the instrument — a transition that NI helped shepherd.

Modeling and Analysis Software

COMSOL (Burlington, MA) announced updates to COMSOL Multiphysics® modeling and simulation software that include a Rotordynamics Module. The module is designed to help engineers analyze vibrations due to centrifugal forces and other gyroscopic effects in rotating machinery. The module helps confirm that rotor vibrations are contained within acceptable design limits by evaluating critical speed, whirl, and bearings. Users can post-process their results directly within the software and present their analysis results as Campbell diagrams, modal orbits, harmonic orbits, waterfall plots, and whirl plots.

Robot Programming Software

With the RISE interactive graphical interface from Hypertherm (Hanover, NH), users control the Robotmaster V6 programming software from within a robot simulation environment. Users can modify a robot’s positions and trajectories by clicking and dragging the robot’s arm, axes, tools, or the workpiece. To manage transition moves between operations, users can jog the robot joint-by-joint; move the robot on the workpiece or tool frames; and change the base, elbow, or wrist configurations. The workspace analysis feature is fully integrated into RISE to help position parts. Visualization of the robot’s reach limits, coupled with dynamic recalculation, shows the impact of changes made on all operations. Process parameters can be created, modified, and controlled by the user for the entire program, specific operations, or at select points.

Manufacturing Connectivity

Sandvik Coromant (Fair Lawn, NJ) introduced the CoroPlus™ platform for connecting manufacturing tools and software. The platform gives users access to product and application data through connected software and hardware from pre- to post-machining. Sensor-equipped tools let users adjust, control, and monitor machining performance in real time. The entire machine shop can be controlled via on-site data dashboards, through the cloud, and via integration with the user’s software and machine environment. The platform connects into existing software environments through open APIs, offering two-way connectivity.

Product of the Month: December 2016

ANSYS AIM 17.2 simulation software from ANSYS, Pittsburgh, PA, features combined fluid thermal and solid thermal-stress capabilities. Momentum and heat sources are available for fluid and conjugate heat transfer analysis, enabling simulations to include such features as electronic package power sources, fans, and filters. New options for optimizing bolted connections allow engineers to model loading and bolt tightening sequences for structural assemblies. Integrated geometry modeling enables users to open data from any CAD system for simulation. Automated meshing tools allow rapid generation of meshes for complex geometries. A flow solution evaluates parameters such as reducing pressure drop, calculating lift and drag coefficients, and evaluating fluid loads. Other features are stress, vibration, and durability analysis; electromagnetic simulation; and simulation of polymer extrusion manufacturing.
