Open-source electronics

The main obstacle to the widespread use of microfiuidics in conjunction with MS is related to the fabrication of such systems. It still requires a considerable effort and costly equipment. Implementation of microchips often necessitates expert knowledge about the device assembly, maintenance, and trouble-shooting. However, the rapidly expanding 3D printing tools, and open-source electronic modules, can cut the costs of fabrication and promote the use of microfiuidic devices in kinetic studies conducted with MS detectors. We anticipate that, in the near future, a microscale total analysis system (pTAS) combining microfiuidics and miniature mass spectrometers will become an omnipresent piece of the laboratory toolkit.

The existence of molecular species in interstellar space has been known for almost seventy years. The first observations involved the electronic spectra, seen in absorption in the near-ultraviolet, of the CN, CH [28] and CH+ [29] species. Radiofrequency lines due to hydrogen atoms in emission [30] and absorption [31], and from the recombination of H+ ions with electrons were also known. However, molecular radio astronomy started with the observation of the OH radical by Weinreb, Barrett, Meeks and Henry [32] in 1963 in due course, this was followed by the discovery of CO [33]. In the subsequent years over 110 molecules have been observed in a variety of astronomical sources, including some in galaxies other than our own. Nearly a third of these are diatomic molecules, with both closed and open shell electronic ground states, and some were observed by astronomers prior to being detected in the laboratory. 

Open Source software must be fully evaluated by the user organization to assess relevant electronic record/signatnre fnnctionality since there is no snpplier acconntable for fnnctionahty definition, product development, or maintenance. Cantion shonld be exercised since it is very difficult to truly demonstrate the trustworthiness of such software in the absence of life-cycle development and support documentation.

In addition to summary reports regarding the supply chain, there are efforts to track the specific details for individual companies sourcing of their products. An open source software application called Source-map ([113]) maps supply chains linked to a dictionary of details such as their carbon footprint, greenhouse gas emissions, lead time, and more. The open source nature of the software enables crowdsourcing of supply chain maps and enables tracking down to the raw material source. The site contains source-maps for electronic products, apparel, food, and many others. The software permits any user to create such maps based on the data they possess and then pass the data along to others to edit and develop. 

Clearly, a bond graph approach to FDI of systems modelled as a hybrid system is not limited to switched power electronic systems but may be applied to other engineering systems as well for which a hybrid model is appropriate. In the following, the case studies consider faults in a DC to DC boost-converter, in a three-phase DC to AC inverter and in a three-phase rectifier AC to DC. In some motor drives, a rectifier and an inverter are used back-to-back [8], Computations have been performed by means of the open source software program Scilab [21],...

Methods to calculate time dependent current/voltage response for circuits whose parameters depend on voltage or current are well developed in theoretical electronics and free open source tools for numerical calculations are available, such as general electronic circuit simulator SPICE (Hageman [1993]). 

EChem++ [9, 14] is based on adaptive finite elements. Both reaction mechanisms and experimental conditions (such as the potential or current program applied to the electrode as an excitation of the electron transfer processes) can flexibly be formulated. It is an open-source program maintaining principles of object-oriented software design [21] and is under continuous development.

This website is based mainly on open source softwares, a becoming popular trend in education. It has proved appropriate and successful in terms of educating biomedical engineering, especially in the advanced programme carried out at Department of Electronic Technology and Biomedical engineering, Hanoi University of Technology for the first time, in cooperation with the University of Wisconsin-Madison, USA. 

Ring opening by intramolecular attack by an electron source located on a /3-carbon is represented by the Wharton reaction (Scheme 62) (8UCS(P1)2363) and the Eschenmoser fragmentation (Scheme 63) (81S276).
