Real-time quality control (qc) of oceanographic data is usually accomplished by testing data points against a variety of conditions to identify the quality of the data. Since 2012, the U.S. Integrated Observing System (U.S IOOS®) Program Office Quality Assurance/Quality Control of Real-Time Oceanographic Data (Qartod) Project has worked with the ocean-observing community both nationally and internationally...
The QARTOD methodology of a standard sequential string of tests on individual measurements has high applicability to constrained data systems. The QARTOD methodology has the benefit of a coherent and replicable test structure that enables relatively easy expansion into new measurements. However, as data streams become more complex the series of tests described becomes increasingly difficult to analyse...
Ocean Networks Canada (ONC) is a not-for-profit society that operates and manages innovative cabled observatories which supply continuous power and Internet connectivity to scientific instruments located in coastal, deep-ocean, and Arctic environments. The data from the instruments are archived, quality-controlled, and made freely available to researchers, educators, and the public. The Oceans 2.0...
The non-iterative algorithm that reveals the general physical basis of measuring processes and instrumental (computer) computations is proposed and investigated. The algorithm is based on the previously proposed postulate and consists in finding the optimal, locally defined width of the averaging interval. The optimal width of the interval provides the smallest error when measuring or computing the...
Communication skills are an integral part of the development of undergraduate students as emerging professionals in rapidly changing, multi-disciplinary engineering fields. However, many engineering educators and industry employers continue to express concerns about the quality of these skills in engineering graduates. Many universities and institutions have enhanced engineering education curriculum,...
This study is focused on the application of the forecast results obtained with the help of a dual-parametric neural network for measuring instruments calibration within a limited range. In this report describing our study we intend to give a theoretical overview of the previous research on the subject. We also consider the learning algorithms for interval neural networks with hidden layer weights...
This paper deals with analysis of CAN BUS using modular measurement system CompactRio from National Instruments and graphical development environment LabVIEW. The main advantage of using this system is that user can receive and transmit CAN messages in one window of program. Send all types of CAN BUS frames is possible. Another benefit is that is possible to simulate behavior of sensor or control...
Multitrack audio mixing is an essential part of music production and one of the first steps consist on processing individual stems from raw recordings. In this paper, we investigate this stage as a content-based transformation. We explore which audio features are relevant to interpret this specific process and which set of features gets modified by the mixing of stems in the most consistent way. We...
These article shows efficiency of Problem-Based Learning (PBL) in academic performance of course “Physics I”, specifically in how learning arises across experience. For this, existing methodologies were adapted in PBL in order to generate six methodological proposals, developed during an academic semester. Impact of PBL was evident at end of semester. It was validated through non-parametric test from...
Many analog and mixed signal devices have very few or no digital pins. In spite of this, these products can be highly complex internally, including significant digital content. They may contain various sensors and control circuitry, which react to a variety of conditions to control the power profile of the part and its environment. These factors can make these devices very challenging to test. They...
This study describes a new method for musical steganography utilizing the MIDI format. MIDI is a standard music technology protocol that is used around the world to create music and make it available for listening. Since no publicly available method for MIDI steganography has been found (even though there are a few methods described in the literature), the study investigates how a new algorithm for...
The architecture of a software-driven testbed is discussed. The test setup has been developed as measurement and instrumentation system to functionally verify and thermally validate the communication subsystems designed and manufactured for the nanosatellite applications. The system is applied for qualification of a communications subsystem currently under consideration for ZA-CUBE-2 mission.
It is important to allow the test engineer great flexibility when developing a test program. Highly skilled test engineers desire flexibility and different hardware platforms to test a Unit Under Test (UUT). In the past, the engineer was told to use specific test equipment and not provided with the option to program an instrument to their specific test and diagnostic plans. Being stuck in a rut on...
Much like the proliferation of different Automatic Test Equipment (ATE) within the DoD Services, there has been a similar proliferation of various programming languages for developing Test Program Sets (TPS) to be used on those same ATE. The use of multiple languages leads to a variety of unfavorable situations, including, among others: • Complexity of re-hosting software to new ATE • Difficulty transitioning...
To utilize the proper test techniques that expand our test and diagnosis process we should regularly evaluate and integrate new devices and new techniques. Willingness to embrace change is the major requirement for successful technology integration. Test technology is continuously and rapidly evolving. It is an ongoing process and demands continual research and understanding. Effective integration...
Almost independent of the program, technology or functionality, the number one issue facing everyone is tackling the ever-increasing desire for tighter design margin. This has not only pushed designers and their simulation tools to the edge, it has kept test and test strategies one step behind the growing measurement needs. The result has been lower yields, greater false failures and a swelling number...
Increased interest in security has resulted in greater demand for automated test systems to comply with security standards. Automated test systems have traditionally been operated in isolated environments because of their unique characteristics. However, changes in United States defense acquisition regulations require that defense contractors bring these test systems into compliance with National...
This paper seeks to compare the various approaches that Terna has taken over time, and their effectiveness, as well as to outline a new approach that can, and whenever possible, must integrate the best practices in the field today for the prevention of conflict within the territory and, above all, for broad social participation in the project choices of our electric works.
• It has been shown that measured SVSWR is smaller than peak SVSWR. The measured SVSWR covers approximately 75% of the SVSWR • An method is shown to use a moving window to estimate the real SVSWR level. The site contribution to emissions measurement MIU can be derived based on the full knowledge of the SVSWR. • SVSWR of the back half of the QZ is not currently considered by the standard, but the levels...
