Before long, the technological benefits of the piezoelectric accelerometer became apparent and in the late 1940s, large scale production of piezoelectric accelerometers began. Today, piezoelectric accelerometers are used for instrumentation in the fields of engineering, health and medicine, aeronautics and many other different industries.
PCB-Investigator is a software tool used for the analysis, visualization, and optimization of printed circuit boards (PCBs). It is used for tasks such as PCB design validation and quality assurance. It is developed by EasyLogix [1] owned by Schindler & Schill GmbH, a German company specializing in electronic design automation (EDA) software.
The world of electronic design automation (EDA) software for integrated circuit (IC) design is dominated by the three vendors Synopsys, Cadence Design Systems and Siemens EDA (Formerly Mentor Graphics, acquired in 2017 by Siemens) which have a revenue respectively of 4,2 billion US$, 3 billion US$ and 1,3 billion US$.
By 1979, the Finnigan GC/MS was the preferred instrument at the EPA for the analysis of environmental pollutants in water and wastewater. [ 1 ] [ 14 ] [ 15 ] The models most generally used were Finnigan Corporation's 1015 and 3000 series of quadrupole mass spectrometers with a data system based on DEC 's PDP-8 computers. [ 14 ]
As a reminder, this analysis of our Q4, our full year 2024 results and our guidance for Q1 2025 is based on non-GAAP and excludes all noncash stock-based compensation impacts, certain acquisition ...
Environmental systems analysis (ESA) is a systematic and systems based approach for describing human actions impacting on the natural environment to support decisions and actions aimed at perceived current or future environmental problems. Impacts of different types of objects are studied that ranges from projects, programs and policies, to ...
The database approach is also used for field data; as a result, the GEMSS viewers can be used to display model results, field data or both, a capability useful for understanding the behavior of the prototype as well as for calibrating the model. The field data analysis features can be used independently using GEMSS modeling capability.
General structure of a PCB. Polychlorinated biphenyls (PCBs) are various biphenyl based artificial products that are widely used as a dielectric fluid, industrial coolant, and lubricants in the 1960s and 1970s.
