This paper describes an experimental study of the three-dimensional flow within two highly loaded turbine cascades subjected to same overall load but different distributions. Data were obtained using pneumatic probes, pressure tappings, and a surface visualization technique. It is found that general nature similar for both cascades. In exit plane show spanwise loss However, averaged secondary quite in this plane. Examining measurements farther downstream also by comparing calculated...
Learning a musical instrument requires regular exercise. However, students are often on their own during practice sessions due to the limited time with teachers, which increases likelihood of mislearning playing techniques. To address this issue, we present Let's Frets - modular guitar learning system that provides visual indicators and capturing finger positions 3D-printed capacitive fretboard. We based design requirements collected through in-depth interviews professional guitarists...

The energy industry is undergoing a major upheaval.In Germany, for example, the large nuclear and coal-fired power plants in gigawatt scale are planned to be shut down forthcoming years.Electricity generated many small units decentralized, renewable environmentally friendly manner.The 1000 MW multistage axial steam turbines used this date no longer suitable these tasks.For reason, authors examine turbine architectures that known per se but have fallen into oblivion due their inferior...
Mastering the guitar requires regular exercise to develop new skills and maintain existing abilities. We present Let's Frets - a modular support system that provides visual guidance through LEDs are integrated into capacitive fretboard practice of chords, scales, melodies, exercises. Additional feedback is provided 3D-printed senses finger positions sensing. envision as an raises awareness guitarists about their playing styles, training progress, composition pieces, facilitating remote...
Micro turbines (<100 kWel) are commercially used as expansion machines in waste heat recovery (WHR) systems such organic Rankine cycles (ORCs). These highly loaded generally designed for a specific parameter set, and their isentropic efficiency significantly deteriorates when the mass flow rate of WHR system deviates from design point. However, numerous industry processes that potentially interesting implementation process, temperature, or both can fluctuate significantly, resulting...
Current systems for enacting scientific experiments, and in particular simulation workflows, do not support multi-scale multi-field problems if they are coupled on the level of mathematical model. We present a life cycle that utilizes notion choreographies to enable trial-and-error modeling execution and/or simulations. The exhibits two views reflecting characteristics top-down bottom-up manner. It defines techniques composing data-intensive, workflows more complex simulations generic,...
Learning a musical instrument requires lot of practice, which ideally, should be done every day. During practice sessions, students are on their own in the overwhelming majority time, but access to experts that support "just-in-time" is limited. Therefore, commonly do not receive any feedback during sessions. Adequate feedback, especially for beginners, highly important three particular reasons: (1) preventing acquirement wrong motions, (2) avoiding frustration due steep learning curve, and...
The interactive augmentation of musical instruments to foster self-expressiveness and learning has a rich history. Over the past decades, incorporation technologies into emerged new research field requiring strong collaboration between different disciplines. workshop "Intelligent Music Interfaces" covers wide range subjects directions, including (a) current challenges in learning, (b) prototyping for improvements, (c) means expression, (d) evaluation solutions.
Resource sharing is an important aspect how cost savings in cloud computing are realized. This especially multi-tenancy settings, where different tenants share the same resource. paper presents approach to merge two application topologies into one, while on one hand preserving functionality of both applications and other enabling similar components. Previous work has not addressed this due lack ways describe composite a decomposed, formal, machine-readable way. New standardization...
In the paper behaviour of five-stage experimental steam turbine 10 MW is described during expansion transition from superheated to wet as well influence on flow path efficiency. The occurrence one four last stages given by setting inlet parameters. wetness behind stage calculated using two methods, first enthalpy drop with output measured water brake and second an optical probe. results both methods are compared. impact increasing a decrease in efficiency observed. individual also loss...
The energy industry must change dramatically in order to reduce CO2-emissions and slow down climate change. Germany, for example, decided shut all large nuclear (2022) fossil thermal power plants by 2038. Power generation will then rely on fluctuating renewables such as wind solar. However, still play a role with respect waste incineration, biomass, exploitation of geothermal wells, concentrated solar (CSP), power-to-heat-to-power (P2H2P), course heat recovery (WHR). While the multistage...
The Business Process Execution Language (BPEL) is a well established language for the definition of process models as service orchestrations. Service orchestrations are used in conjunction with choreographies order to create distributed, complex service-based applications. An important requirement such applications need flexibility during both their modeling and execution. This work builds on this by proposing an extension BPEL allow abstract constructs level executable models. Such can be...
