We describe the algorithms for the simulation of cw and pulsed coherent Doppler wind lidar operation in a turbulent atmosphere and the methods to estimate the mean wind and the parameters of small-scale wind turbulence from lidar data. The algorithms are realized as LabView computer codes, which include parts simulating the atmospheric turbulent wind fields based on the Karman model, lidar signal, and data processing. The errors for lidar measurement of turbulent parameters and the retrieval of the wind vertical profiles are estimated based on a computer simulation of the coherent Doppler lidar system operation.

<div class="htmlview paragraph">The boundary layer dynamics of brake systems is characterized by the growth and destruction of hard and friction intensive patterns on the brake pad. These mesoscopic “patches” essentially determine the brake's global friction- and wear behavior. That paper shows, how, based on this theory, global phenomena can be simulated with an innovative dynamic friction law within different timescales. Subsequently a Cellular Automaton model is extended by the definition of additional inner variables describing a three-dimensional surface topography of brake pads. This model is applied to a longtime-simulation of the profile changing and a simulation regarding varying external loads. These results are compared to microscope-measurements of pads after different loading procedures which have a significant impact to the height profile.</div>

Abstract The perpendicular v 3 fundamental band of the H3O+-ion has been remeasured with a colour centre laser. Improved results have been achieved by combining our experimental data with the recently published line positions of Begemann et al. and Bunker et al. For the first time the l-type doubling constant for the a-species has been determined, together with an additional l-type resonance parameter which describes the splitting of the (Kl) = -2 level.

One major result of the Industrial Digitalization is the access to a large set of digitalized data and information, i.e. Big Data. The market of analytic tools offers a huge variety of algorithms and software to exploit big datasets. Implementing their advantages into one approach brings better results and empower possibilities for process analysis. Its application in the manufacturing industry requires a high level of effort and remains to be challenging due to product complexity, human-centric processes, and data quality. In this manuscript, the authors combine process mining and value streams methods for analyzing the data from the information management system, applying the approach to the data delivered by one specific manufacturing system. The manufacturing process to be examined is the process of assembling gas meters in the manufacture. This specific and important part of the whole supply-chain process was taken as suitable for the study due to almost full-automated line with data about each process activity of the value-stream in the information system. The paper applies process mining algorithms in discovering a descriptive process model that plays the main role as a basis for further analysis. At the same time, modern techniques of the bottleneck analysis are described, and two new comprehensible methods of bottlenecks detection (TimeLag and Confidence intervals methods), as well as their advantages, will be discussed. Achieved results can be subsequently used for other sources of big data and industrial-compliant Information Management Systems.

The cycloaddition of spirobutenolide 3 to the homochiral cyclopentadiene 1 at 6.5 kbar leads exclusively to cycloadduct 5. Subsequent Diels-Alder or Michael additions again favour the cyclohexenone double bond; this perfect chemo- regio- and face selectivity was employed for a short and efficient approach to the wistarin framework.

This article summarises the activities of Honeywell Sondertechnik in Maintal Germany in the development and prototyping of a new low cost land navigation system (ILANA) with a minimum amount of inertial sensors. The system utilises one GG1308 ring-laser-gyro, two vibrating beam accelerometers RBA500 and a hodometer. To aid the system, a Global Positioning System (GPS) receiver and the possibility for manual position fixes have been incorporated. System evaluation featured the Standard-Positioning-Service (SPS) and the Precise-Positioning-Service (PPS) of GPS. This effort has been conducted by Honeywell Sondertechnik in the time span 1992-1993. It highlights the important technical aspects and presents major test results.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

6Li magic angle spinning (MAS) nuclear magnetic resonance spectroscopy has been used to study the structure of a series of LiMn2O4 spinel samples prepared using different annealing methods. The results show that the annealing conditions affect the number of defect sites within the structure; higher annealing temperatures leading to a spinel sample with fewer defects. Analysis of the peak intensities in the NMR spectra revealed that the structural evolution of the spinel samples with temperature is dependent upon particle size. A series of chemically delithiated samples have also been studied using a combination of 6Li MAS NMR, X-ray diffraction and infrared spectroscopy in order to follow the structural changes that occur upon delithiation. The NMR spectra of the delithiated samples, LixMn2O4, exhibit a gradual shift in the position of main spinel resonances (i.e. Li in 8a tetrahedral sites) with decreasing lithium content for 0.3 < x < 1.0. For x < 0.3, the delithiated samples exhibit a new 6Li resonance at ∼950 ppm. This resonance is assigned to lithium present in 8a sites in a Mn4+-rich phase at the centre of the spinel particles. This assignment is supported by FT-IR data and crystallite size measurements (XRD), which suggest that HMn2O4 forms on the surface of the particles in the heavily delithiated samples.

This work presents the major characteristics and lessons learned by the development and prototype implementation of an event-oriented and cloud-based SCADA system that is constructed using a microservice architecture. The microservices are then utilized to propose an approach for implementing product-driven production systems under the RAMI4.0 specification.

The integration of distributed embedded systems is error-prone even though the components themselves are error-free. Test automation is getting more and more common in industry to find errors in such complex systems. Our approach uses time-dependent cause-and-effect graphs to describe test cases considering distribution and real-time properties. The use of test object structure benefits better testing depth. We suggest neutral description of test object to decouple proprietary CAE tools for test object management from test automation tools. A simple language describing test objects consisting of modules and connections was defined and realized. It enables graphical documentation and context-sensitive protocol analysis. Symbolic representation of received messages facilitates better comprehension of system behaviour. All concepts are tried and evaluated in the laboratory with building security equipment.

Recent research has focused on developing air-coupled transducers for use in industrial flow measurement applications. Optimal performance of ultrasonic transducers is only achieved with maximum energy transfer. Unfortunately, the significant acoustic impedance mismatch between the active layer and the load medium (i.e. air) in sensors reduces considerably the effective ultrasonic energy transmission and reception, with most of the energy reflected at the interface. Improved matching layers with an appropriate acoustic impedance and attenuation coefficient as low as possible can significantly improve the power efficiency and sensitivity of devices, decreasing energy loss by scattering. The aim of this research is to evaluate novel acoustic materials for use in a new ultrasonic transducer assembly process involving cost effective advanced manufacturing methods. More efficient and consistent signal shapes could be achieved by substituting current matching layers (e.g. syntactic foams) with new materials. Nanocomposite foams can be obtained via cost effective extrusion/moulding processes where microbubbles are formed inside the polymer when heated above a certain temperature. The reduction in density affects acoustic impedence, ultimately creating light passive layers for ultrasonic applications manufacturable in high volumes.

Using a rotating sensor to take acoustic measurements of geological formations from a fluid-filled borehole is common in the oilfield industry. The deployment of ultrasonic devices enables characterizations of the borehole diameter (caliper) and detailed well bore shape, as well as geological or geomechanical interpretations of formation features such as fractures, rock fabric, stress orientations, failure mechanics and borehole damage. A common mode of operation adopts the ultrasonic pulse-echo technique to achieve a sufficiently high spatial resolution. High-resolution imaging is desirable to improve the ability to discern and characterize morphological features in the borehole surface, which can play a significant role for the production of the reservoir. This paper presents experimental high-resolution investigations using ultrasonic pulse-echo measurements with focused transducers on a range of water-immersed target shapes in a laboratory setup. The targets are composed of combinations of nylon, aluminum, and steel. To facilitate a comparison with numerical modelling, simplified benchmark geometries have been machined into the otherwise planar targets. Here, we report results on notches, cylindrical, and spherical defects. The scanned targets thus represent borehole features, such as borehole breakouts-a form of localized damage of the formation. Fluid-coupled measurements of echo amplitudes and pulse-echo round trip times for 1D or 2D scans were obtained. These scans at nominally vertical incidence were repeated at various sensor standoffs to characterize the response and resolution of the focused transducers. To support the understanding of the spatial sensitivity, numerical acoustic wave field simulations were performed using a k-space pseudo-spectral model of linear elastic wave propagation, available as an open source third party toolbox (named k-Wave®) for MATLAB®. We determine the spatial sensitivity of focused transducers and find a good agreement between the experimental results and the model predictions for these simplified benchmark geometries. We identify the arrival of late echoes after multiple reflections inside of concave recesses and examine how these features can lead to misidentifications of the apparent standoff from the surface without suitable processing.

Mesoscale models (parameterized from molecular models) have been previously reported [1-2] which simulate interfacial failure of both flat and rough epoxy-copper oxide interfaces, and demonstrate how coarsegrained models could be used to predict interfacial properties and mechanical failure. The work was targeted at understand molding compound failure [3-4]; however, all molding compounds are highly filled and the aspect of the filler had not yet been addressed. The current paper reports the continued efforts to explore the use of mesoscale models by adding in the effect of the filler on the mechanical response of the epoxy. This work was supported in part by the NanoInterface Consortium funded from the Seventh Framework Program for Research and Technological Development (FP7) of the European Union (NMP3-SL-20080214371).

An effective organizational structure can enhance two-way information flow as well as facilitate project supervision and control. Progress books other than standard engineering or laboratory notebooks are recommended to document task progress without technical detail. Regular project meetings and more frequent sub-unit meetings are the primary modes of communication. Basic agendas for both initial and subsequent meetings are provided.

Within the framework of an engineering design project, great emphasis is placed on the availability of modern technical resources and talented personnel However project organisation, monitoring and reporting, together with the psychological requirements of project management, are all too often overlooked to the detriment of the final product

Acoustic non-destructive evaluation is widely used in the oilfield industry to evaluate the state of the material behind the steel pipes, called casings, which are used in the construction of subterranean oil and gas wells to retrieve hydrocarbons. The annular region between a casing and the surrounding geological formation is usually cemented to provide mechanical support for the casing as well as to ensure zonal isolation between different geological layers. The proper placement of the cement is typically evaluated using sonic and ultrasonic techniques. However, these measurements are often perturbed in the presence of a liquid-filled microannuli, a thin layer of liquid between the pipe and the cement, which renders the interpretation prone to ambiguity and error. To reduce uncertainties in the presents of microannuli, we investigate the benefits of supplementing the industry-standard thickness mode resonance technique with a measurement using the zero-order extensional mode. We built a full analytical model of a cemented borehole which included all the layers present and allowed to finely tune the boundary conditions between them. To validate this model, we developed an experimental apparatus and a set of procedures to produce highly controlled cases of liquid-filled microannuli in the lab. Finally, we benchmarked the results of the model against these experimental scenarios. The validity of the analytical model was evaluated through the comparison with several experiments. We showed that the model's predictions were consistent with the experimental results and allowed a comprehensive assessment of the presence of liquid-filled microannuli. Using our modeling approach, we further demonstrated that the presence of a liquid-filled microannulus lead to a much stronger response of the zero-order extensional mode (compared to the other techniques) due to its high sensitivity to shear coupling between the steel and the annular material. As a result, we propose to complement the current pulse-echo measurement with a pitch-catch measurement based on the zero-order extensional mode of the pipe which allows a much easier and less ambiguous detection of liquid-filled microannuli.

Zusammenfassung In der Öl- und Gasproduktion wird nach der Bohrung ein Stahlrohr, genannt Futterrohr, in das mehrere Kilometer tiefe Bohrloch eingeführt und der Ringraum zwischen Rohr und Gestein, genannt Annulus, mit Zement verfüllt. Die vollständige Füllung des Ringraums mit Zement bewirkt eine hydraulische Isolation der verschiedenen Produktionszonen: jegliche Flüssigkeits- oder Gasbewegung außerhalb des Futterrohres wird unterbunden, um mögliche Verschmutzung von Grundwasserschichten und Unfälle zu verhindern. Um die korrekte Füllung des Ringraums zu überprüfen, wird der Zement im Annulus nach Aushärtung in-situ durch akustische Messungen vermessen. Solche zerstörungsfreien Messungen müssen unter harschen Bedingungen (Sensortechnik und Elektronik arbeiten bei Drücken bis zu 2000 bar und Temperaturen bis zu 200°C) von der Innenseite des Futterrohres ausgeführt werden. Diese Messung soll mögliche Kanäle erkennen, die zu unerwünschten Flüssigkeits- oder Gasbewegungen außerhalb des Futterrohres führen können. Die genauesten Messungen basieren auf Ultraschalltechniken, die entweder den Abklang der natürlichen Resonanz des Futterrohres ausnutzen oder die Eigenschaften der niedrigsten symmetrischen und antisymmetrischen Schwingungsformen von Lambwellen im Futterrohr basieren. Das Gesamtvolumen aller Zementevaluierungsmessungen in der Öl- und Gasindustrie beläuft sich pro Jahr auf mehrere Milliarden Euro.
