76-81 GHz Millimeter Wave Radar Sea Surface and Maritime Target Measurements

Imaging radar measurements of sea surface clutter/reflections and targets of opportunity in the 76-81 GHz frequency band. Part of the University of Birmingham data collection for the EPSRC funded STREAM project (EP/S033238/1)

High Tech Professionals Are Hard to Organize Too

[Excerpt] It is unlikely that any technical and professional employees will be organized in non-union high tech firms until more blue-collar production workers become union members. There are, however, some high technology companies which already have heavily unionized blue-collar workforces. Two industrial unions have recently tried to recruit new members among the engineering and computer personnel at such firms. The experiences of the Communications Workers of America (CWA) at AT&T Technologies and the International Union of Electronic, Electrical, Technical, Salaried, & Machine Workers (IUE) at Raytheon indicate that the obstacles facing unions in this type of high tech organizing are formidable

Gateway Electromagnetic Environmental Effects (E3) Requirements

Electromagnetic Compatibility (EMC) is essential to the success of any vehicle design that incorporates a complex assortment of electronic, electrical, and electromechanical systems and sub-systems that is expected to meet operational and performance requirements while exposed to a changing set of electromagnetic environments composed of both man-made and naturally occurring threats. The combined aspects of these environments are known as Electromagnetic Environmental Effects (E3). The attainment of EMC is accomplished through the application of sound engineering principles and practices that enable a complex vehicle or vehicles to operate successfully when exposed to the effects of its expected and/or specified electromagnetic environments

Effect of the anodization voltage on the porewidening rate of nanoporous anodic alumina

A detailed study of the pore-widening rate of nanoporous anodic alumina layers as a function of the anodization voltage was carried out. The study focuses on samples produced under the same electrolyte and concentration but different anodization voltages within the self-ordering regime. By means of ellipsometry-based optical characterization, it is shown that in the porewidening process, the porosity increases at a faster rate for lower anodization voltages. This opens the possibility of obtaining three-dimensional nanostructured nanoporous anodic alumina with controlled thickness and refractive index of each layer, and with a refractive index difference of up to 0.24 between layers, for samples produced with oxalic acid electrolytes

COSMOS dataset for co-existence/ interference analysis and simultaneous scene representation by automotive radar and video with GPS/IMU ground truth - Sub-Dataset C

The objectives of the described radar trials were to conduct radar measurements at the background of interference in the 76 – 81 GHz frequency band to: • Estimate the impact of interference in an adaptive cruise control (ACC) and cross-traffic alert (CTA) scenarios. • Analyse radar field of view shadowing due to a close target. • Identify an oncoming vehicle from the received interference which is otherwise blind due to radar field of view (FoV) obstruction. • Estimate the multipath interference in a reflective scenario. Repository Overview: The full dataset collected during the trails is over 2 TB. Depending upon the scenario and data collection duration, the size of raw data captured from INRAS Radarlog varies from 1 GB to 7 GB whereas for INRAS Radarbook, it varies from 1 GB to 4 GB. Therefore, due to extremely large files sizes, only the most suitable representative of the defined use-cases is included in the repository. Moreover, the full post-processed radar imagery is only shown for a few example cases. Additional data may be available on request
