Abstract:
The Inertial Measurement Unit (IMU) [1] is a cornerstone technology in various fields, ranging from aerospace to consumer electronics, where accurate motion tracking is paramount. Central to the effectiveness of an IMU is the quality of data processing, particularly in the context of filtering techniques. This study compares two filtering methods: Complementary Filters and Kalman Filters, in their application to IMU data processing. Complementary Filters, known for their simplicity and efficiency, contrast with the more complex but potentially more accurate Kalman Filters. Our investigation de

Abstract:
Measurement achieved in the physical sciences as some kind of mapping on a continuum partitioned into equal units from an origin is understood readily. However, measurement is also an advanced concept, the achievement of which has been integral to the remarkable progress of physical science. This article specializes the probabilistic Rasch model for a finite number of ordered response categories to a response structure which is analogous to measurement - the parameters are expressed in the multiplicative metric giving a natural origin of O, the thresholds partitioning the continuum are made eq

Abstract. With the availability of multi-port vector network analyzers, the need for automated, calibrated measurement facilities increases. In this contribution, a calibration-measurement unit is presented which realizes a repeatable automated calibration of the measurement setup as well as a user-friendly measurement of the device under test (DUT). In difference to commercially available calibration units, which are connected to the ports of the vector network analyzer preceding a measurement and which are then removed so that the DUT can be connected, the presented calibration-measurement u

Abstract:
High-speed electric drive units promise improved power density and, theoretically, driving range of battery electric vehicles. An essential step of the development process is extensive testing of the drive unit on a test rig. In particular, at a high rotational speed level, experimental testing can be challenging. This paper describes a test rig for investigating the overall function of a high-speed drive unit and the transmission’s efficiency and dynamics. The high-speed drive unit developed in the Speed4E research project was the reference drive unit. The test rig is based on the concept of

Abstract:
Most ultra-precision machine tools for fabricating optical lenses and lens molds have on-machine measurement units that can be used for form measurement with the workpiece held on the main spindle. However, for lenses with high numerical apertures, such as pick-up lenses for Blu-ray discs and their molds, the form measurement needs to be made even at a large angle of inclination, which is not feasible with a conventional on-machinemeasurement unit. In this study, an on-machine measurement unit with a measurement angle range±75 degrees is developed. Its performance assessment shows that it has

The necessary accuracy of phasor measurement in these conditions is provided by appropriate digital processing of electrical quantities.

Sensitive devices are affected by extreme vibration excitations during operation so require isolation from high levels of vibration excitations. When these excitation characteristics of the devices are well known, the vibration isolation can be achieved accurately. However, it is possible to have expected profile information of the excitations with respect to frequency. Therefore, it is practical and useful to implement this information in the design process for vibration isolation.

The PMU has been found to carry great deal of value for applications in the wide area monitoring of power systems. Historically, deployment of these devices has been limited by the prohibitive cost of the device itself. Therefore, the objective of the conventional optimal PMU placement problem is to find the minimum number devices, which if carefully placed throughout the network, either maximize observability or completely observe subject to different constraints. Now due to improved technology and digital relays serving a dual use as relay & PMU, the cost of the PMU device itself is not the

AbstractThe concept of measurement in which the magnitude of a property is quantified in a common unit relative to a specified origin is a deep abstraction. This chapter shows the application of measurement in a social science context where the motivation is transparency and equity rather than the advancement of scientific laws. However, to achieve these, the realization of measurement needs to be no less rigorous than it is in the advancement of scientific laws. Rasch measurement theory provides the basis for such rigor.
