Abstract:
AbstractThis article revisits the interplay between enterprise, technology, science, and the state in the latter stages of Prussia's “early industrialization.” Tracing the footsteps of Werner Siemens as he sought to establish a business in Berlin during the 1840s, it highlights the social networks that enabled individuals and ideas to circulate between the military establishment, administrative departments, scientific circles, and entrepreneurial communities. At heart, these abstract entities constituted dense clusters of individuals who shared strong connections to one another, but whose contacts with other groups also enabled them to mobilize resources. During the 1840s, fostered by the dynamism of Berlin's expansion, social networks stepped into the breach caused by the Reform Era's upheaval of traditional employment structures and the emergence of a market economy. They provided a means of negotiating the uncertain socioeconomic circumstances that characterizedVormärzPrussia.

Abstract:
Der aus Quakenbrück (Münsterland) gebürtige Jurist Heinrich Friedrich Wilhelm André (1827 – 1903), von 1874 bis 1896 Oberbürgermeister der sächsischen Industriemetropole Chemnitz, hat wesentlichen Anteil an der Schaffung des deutschen Reichspatentgesetzes. In Zusammenarbeit mit Werner Siemens und unterstützt durch einen speziellen Ausschuss des VDI konnte zunächst ein „Entwurf eines Patentgesetzes für das Deutsche Reich“ erstellt werden Dieser regelte den Gegenstand des Patentschutzes und das Erteilungsverfahren, die Aufgaben der Patentbehörden (Patentamt und Reichsoberhandelsgericht) sowie mögliche Rechtsstreitigkeiten. Die Vorlage dieses Entwurfs auf der Patentkonferenz auf der Wiener Weltausstellung (1873) unter Vorsitz von Dr. Charles William Siemens, einem der Siemens-Brüder, beförderte die baldige internationale Verständigung über den Patentschutz. Im Mai 1874 erfolgte daraufhin die Gründung des Deutschen Patentschutzvereins, gefolgt vom Erlass des Markenschutzgesetzes und des Musterschutzgesetzes (1876). 1876 veröffentlichte der Verein den Entwurf für ein Deutsches Patentgesetz. Nachdem die Landesregierungen ihr Einverständnis erklärt hatten, die kaiserlichen Genehmigungen sowie die Billigung von Bundesrat und Reichstag vorlagen, wurde das Gesetz und am 25. Mai 1877 schließlich verkündet. Am 1. Juli 1877 trat das 45 Paragraphen umfassende Gesetzeswerk in Kraft. Dr. André engagierte sich auch fürderhin in Sachen Patentwesen und Gesetzeswerk, nahm wissenschaftliche Untersuchungen vor und sorgte für juristische Präzisierung und Vervollständigung, so dass am 7. April 1891 ein neues Patentgesetz erlassen werden konnte. In Anerkennung dieser Leistungen urteilte das amerikanische Journal of the Patent Office Society: „It can not be gainsaid that the German patent system was the finest in the world.“
The jurist André Heinrich Friedrich Wilhelm (1827 - 1903), born in Quakenbrück (Münsterland) and from 1874 to 1896 Lord Mayor of the industrial city of Chemnitz, Saxony, played a major role in the creation of the Patent Law of the German Reich. In collaboration with Werner Siemens and supported by a special committee of the VDI at first he drew up a "Draft Patent Law for the German Reich". It regulated the subject of patent protection and the granting procedure, the tasks of the patent office (Patent Office and the Reich Chief Commercial Court) and possible litigation. The presentation of this draft at the Vienna World Exhibition Conference (1873) under the chairmanship of Dr. Charles William Siemens, one of the Siemens brothers, promoted the upcoming national and international understanding of patent protection. The German Patent Protection Association was founded in May 1874. It was followed by the enactment of the Trademark Act and the Design Protection Act (1876). In 1876 the Association published a draft of a German patent law. After the regional governments had given their consent, there were royal approvals and the approval of the Bundesrat and the Reichstag. The law was announced on 25th of May 1877. On 1st July 1877 the comprehensive piece of legislation with 45 paragraphs came into force. From then onwards Andre was also involved in matters regarding the patent system and its legislation, undertook scientific studies and provided legal clarification and completion. On 7th of April 1891 a new patent law was adopted. In recognition of this achievment the Journal of the American Patent Society Office acclaimed: "It can not be gainsaid that the German patent system was the finest in the world."

Abstract:
Cette thèse propose une approche transversale entre différentes disciplines : musicologie historique, musicologie analytique (analyse des œuvres et génétique de l’œuvre) et sociologie des arts (analyse socio-économique et analyse sociologique de la trajectoire de l’œuvre). Les compositeurs de la « Nouvelle Simplicité » sont à l’origine d’un courant compositionnel très large réintégrant les formes musicales traditionnelles dans une interprétation nouvelle, réactivant la fonction de la polarité des consonances et des dissonances. La notion de « simplicité » et les idées qui ont émergé de ce concept ont ainsi été un catalyseur qui a participé à l’établissement du postmodernisme en Allemagne. Toutefois, la génération de la « Nouvelle Simplicité » et leurs idées et concepts en communs ont trouvé une fin brutale avec la chute du mur de Berlin et les changements culturels et politiques induits par ce bouleversement. Les évolutions politiques et la création d’une nouvelle Akademie der Künste Berlin qui représentait une fusion de l’Akademie der Künste Berlin est et ouest ont abouti à une opposition entre deux signataires du premier manifeste de cette génération de compositeurs : W. Rihm, avec son abstention du débat, et H-J. von Bose, avec son retrait de l’Akadémie der Künste Berlin (il sera suivi de plusieurs autres artistes tels que G. Ligeti et G. Baselitz). Cela marque la fin définitive de la collaboration de cette génération de compositeurs
This thesis proposes a cross-disciplinary approach between: historical musicology, analytical musicology (analysis of pieces and the genetics of the piece) and art sociology (socio- economic analysis and sociological analysis of artistic practice). The "New Simplicity" composers were the source of a very wide compositional current reintegrating traditional musical forms in a new interpretation, reactivating the function of the polarity of consonance and dissonance. The notion of "simplicity" and ideas that emerged from this concept were a catalyst that contributed to the establishment of postmodernism in Germany. However, the generation of the "New Simplicity" and their shared ideas and concepts came to an abrupt end with the fall of the Berlin Wall and the cultural and political changes induced by this upheaval. Political developments and the creation of a new Akademie der Künste Berlin representing a fusion of Akademie der Künste Berlin East and West led to an opposing position between two first manifesto signatories of this generation of composers: W. Rihm with his abstention from the debate and H-J. von Bose with his withdrawal from the Akademie der Künste Berlin in common with many other artists such as G. Ligeti and G. Baselitz, marking the definitive end of the collaboration of this generation of composers

Abstract:
Das Bereitstellen von Parametern bezüglich Auflösungsvermögen und effektiver Auflösung ist ein gut erforschtes Wissenschaftsfeld, dennoch sind noch einige offen Fragen zu klären, wenn eine standardisierte Erhebung angestrebt wird. Zu diesem Zweck ist im Rahmen der vorliegenden Arbeit ein Framework definiert und mathematisch und methodologisch beschrieben worden unter Einbeziehung aller untergeordneten Prozesse. Weiterhin liefert sie einen detaillierten Überblick zu den verwendeten Methoden und Strukturen, um räumliche Auflösung zu messen. Das zuvor definierte Framework wird darüber hinaus genutzt, um alle zugehörigen Probleme bezüglich eines genormten Prozesses zu identifizieren und zu lösen. Der so definierte Prozess ist außerdem Teil der bevorstehenden, neuen Norm: DIN 18740-8. Im Hinblick auf die Norm sind alle Messeinflüsse an den möglichen Stellen quantifiziert worden und an Stellen, wo dies nicht möglich ist, wurden Vorkehrungen definiert, die diese Einflüsse mindern. Darüber hinaus wurde ein zugehöriges Softwaretool entwickelt, das ebenfalls die neue Norm unterstützt. Als weiterer Schwerpunkt dieser Arbeit wurde ein Verfahren zur Verbesserung der räumlichen Auflösung entwickelt und bewertet. Das zugehörige Softwaretool kombiniert dabei verschiedene Super-Resolution-Ansätze unter Einbeziehung zusätzlicher Kenntnis über die Bildqualität. Der neuartige Super-Resolution-Ansatz verbessert die räumliche Auflösung von Luftbildern und True-Ortho-Mosaiken indem er ein Set von niedrig aufgelösten Rohbildern, deren optimierter, äußerer und innerer Orientierung und die abgeleitete 3D-Oberfläche als Eingangsdaten akzeptiert. Anschließend werden ein oder mehrere hochaufgelöste Bilder als hybride Kombination von klassischen Super-Resolution-Methoden und De-Mosaikierung berechnet, unter Berücksichtigung der photogrammetrischen Projektionen auf die 3D-Oberfläche. Dabei werden Limitierungen der Bildkoregistrierung mit üblich verwendeten Optical-Flow-Ansätzen überwunden.
Although acquisition of resolving power and effective spatial resolution is a well-studied field of research, there are still several scientific questions to be answered when it comes to a standardized determination. Therefore, this thesis provides a description of a framework for the imaging process of remote sensing sensors mathematically and methodologically including imaging components and subsequent processes. Furthermore, a detailed review for different structures and methods to measure spatial resolution is included. Aforementioned framework then is utilized to identify related issues to a standardized process obtaining spatial resolution parameters as an image quality criterion to support an upcoming standard DIN 18740-8. With respect to define the norm-procedure every measurement influence is quantified where possible and in other cases arrangements are specified to diminish their influence. Moreover, the development of an associated software measurement tool has been accomplished as part of this thesis, which also supports the norm for aerial image quality, spatial resolution in particular. As part of a further objective of this thesis, a super-resolution approach to improve spatial resolution of aerial images has been developed and evaluated. The related software tool is able to combine different super-resolution techniques and includes known image quality parameter in subsequent calculations. The novel super-resolution approach improves spatial resolution of aerial imagery and true ortho-mosaics by taking a set of multiple low-resolved raw images (color filter array), their optimized exterior and interior orientation parameters and the derived 3D-surface as input. Then, one or more super-resolved images are calculated as a hybrid of classic super-resolution method and demosaicing while considering photogrammetric back-projections onto the 3D-surface. Thereby, limitations of image co-registration with commonly used optical flow approaches can be neglected.

Abstract:
This paper summarizes progress on Siemens Westinghouse’s Advanced Turbine Systems (ATS) Program. The ATS program, which is supported by U.S. Department of Energy, Office of Fossil Energy, has the ultimate objective of introducing into the utility market electricity generating systems capable of achieving greater than 60% LHV based net plant thermal efficiency, less than 10 parts per million NOx emissions, 10% electricity cost reduction and state-of-the-art reliability-availability-maintainability. Work has been in progress over the last few years on developing the required advanced technologies and designing the W501ATS gas turbine. The main thrust of the technology development effort was in the areas of compressor aerodynamics, turbine aerodynamics, heat transfer/cooling, sealing, combustion/emissions, single crystal casting, materials, and coating systems. These technologies were incorporated into the W501ATS engine design to ensure that the ATS Program goals will be achieved.

Abstract:
Siemens gas turbine history can be traced back to the early years of World War II. The Westinghouse aero jet engine (J 30) and the Junkers JUMO 004 jet engine were the basis for the industrial gas turbines designed and manufactured by Westinghouse and Siemens / Kraftwerk-Union since World War II. KWU was formed in 1969 as a joint venture of AEG and Siemens and became wholly owned by Siemens in 1977. AEG worked with Junkers on the development of the Jumo 004 jet engine during the War. Westinghouse Power Generation was purchased by Siemens in 1998. This paper examines the history of those early gas turbines and traces the evolution of the modern Siemens gas turbine from that time. Details are also given of the latest Siemens gas turbine to enter into operation, the 340MW SGT5-8000H.

Abstract:
This paper summarises achievements in the Siemens Westinghouse Advanced Turbine Systems (ATS) Program. The ATS Program, co-funded by the U.S. Department of Energy, Office of Fossil Energy, was a very successful multi-year (from 1992 to 2001) collaborative effort between government, industry and participating universities. The program goals were to develop technologies necessary for achieving significant gains in natural gas-fired power generation plant efficiency, a reduction in emissions, and a decrease in cost of electricity, while maintaining current state-of-the-art electricity generation systems’ reliability, availability, and maintainability levels. Siemens Westinghouse technology development concentrated on the following areas: aerodynamic design, combustion, heat transfer/cooling design, engine mechanical design, advanced alloys, advanced coating systems, and single crystal (SC) alloy casting development. Success was achieved in designing and full scale verification testing of a high pressure high efficiency compressor, airfoil clocking concept verification on a two stage turbine rig test, high temperature bond coat/TBC system development, and demonstrating feasibility of large SC turbine airfoil castings. The ATS program included successful completion of W501G engine development testing. This engine is the first step in the W501ATS engine introduction and incorporates many ATS technologies, such as closed-loop steam cooling, advanced compressor design, advanced sealing and high temperature materials and coatings.

Full text
Abstract:
Associated gases at oil wells are often rich in heavy hydrocarbons (HHC, here denoting hydrocarbons heavier than propane). HHC cause handling difficulties and the combustion properties are quite different from standard natural gas. For this and other reasons HHC rich associated gases are often flared or vented. This is an enormous waste of useable energy and a significant contribution to emissions of pollutants, global CO2 and other greenhouse gases. Siemens Industrial Turbomachinery AB in Finspong (SIT AB) recently tested a standard DLE 25 MW SGT-600 gas turbine and a standard 31 MW SGT-700 gas turbine with HHC rich natural gas. Pentane was chosen as a model substance for HHC. The tested gases had up to 30% of the fuel heating value from pentane. The unmodified standard DLE gas turbines proved to be very tolerant to the tested pentane rich gases. CO emissions were reduced with increasing pentane content in the fuel for the same power output. NOx was observed to increase linearly with the pentane content. Combustion dynamics was affected mildly, but noticeably by the pentane rich fuel. This result, together with earlier presented results for the same DLE engines on nitrogen rich natural gases, gives an accepted and tested total LHV range of 25–50 MJ/kg and Wobbe index range of 25–55 MJ/Nm3. No special adaptation of the gas turbines was necessary for allowing this wide fuel range. The benefit of increased and proven fuel flexibility is obvious as it allows the gas turbine owner to make full use of opportunity fuels and to supply power at low fuel cost.

The leading technology of the Siemens SGT5-4000F heavy duty gas turbine is demonstrated through recent engine measurements at customer sites. The 4000F fleet comprises more than 240 engines that exceed performance targets because of well established, non-heuristic design processes that are continuously enhanced. On-site measurements of pressure, temperature and flow were performed at various locations in the flow path of the 4-stage turbine to support validation of Siemens’s proprietary 3D Computational Fluid Dynamics (CFD) analysis suite. Despite inherent but well understood modeling deficiencies, these advanced CFD prediction capabilities surpassed other tools and increased the accuracy of the overall turbine design process. The performance of each turbine stage and flow features related to the exhaust diffuser were captured by the calculations. Overall performance characteristic shapes coincided with heat balances based on measurements. Radial traverses at the turbine exit, static pressure along the engine axis, and temperature sensors were matched well. The level of accuracy in delta predictions exceeded industry standards. The design suite was able to predict performance parameters prior to measurement within respective confidence levels. Therefore, this advanced 3D CFD design suite, validated with the test data, will form the basis for future turbine development programs.

Abstract:
The standard design process for the Siemens Industrial Turbomachinery, Lincoln, Dry Low Emissions combustion systems has adopted the Eddy Dissipation Model with Finite Rate Chemistry for reacting computational fluid dynamics simulations. The major drawbacks of this model have been the over-prediction of temperature and lack of species data limiting the applicability of the model. A novel combustion model referred to as the Scalar Dissipation Rate Model has been developed recently based on a flamelet type assumption. Previous attempts to adopt the flamelet philosophy with alternative closure models have failed, with the prediction of unphysical phenomenon. The Scalar Dissipation Rate Model (SDRM) was developed from a physical understanding of scalar dissipation rate, signifying the rate of mixing of hot and cold fluids at scales relevant to sustain combustion, in flames and was validated using direct numerical simulations data and experimental measurements. This paper reports on the first industrial application of the SDRM to SITL DLE combustion system. Previous applications have considered ideally premixed laboratory scale flames. The industrial application differs significantly in the complexity of the geometry, unmixedness and operating pressures. The model was implemented into ANSYS-CFX using their inbuilt command language. Simulations were run transiently using Scale Adaptive Simulation turbulence model, which switches between Large Eddy Simulation and Unsteady Reynolds Averaged Navier Stokes using a blending function. The model was validated in a research SITL DLE combustion system prior to being applied to the actual industrial geometry at real operating conditions. This system consists of the SGT-100 burner with a glass square-sectioned combustor allowing for detailed diagnostics. This paper shows the successful validation of the SDRM against time averaged temperature and velocity within measurement errors. The successful validation allowed application of the SDRM to the SGT-100 twin shaft at the relevant full load conditions. Limited validation data was available due to the complexity of measurement in the real geometry. Comparison of surface temperatures and combustor exit temperature profiles showed an improvement compared to EDM/FRC model. Furthermore, no unphysical phenomena were predicted. This paper presents the successful application of the SDRM to the industrial combustion system. The model shows a marked improvement in the prediction of temperature over the EDM/FRC model previously used. This is of significant importance in the future applications of combustion CFD for understanding of hardware mechanical integrity, combustion emissions and dynamics of the flame.

Abstract:
In order to further extend the turbine fuel flex capability, a test under atmospheric conditions of a full-scale SGT-400 burner was performed to study the combustion behavior when operating on hydrogen enriched natural gas. A high speed camera was installed in the rig to investigate the flame dynamics on different operation conditions. NOx emissions were measured for all presented conditions. The combustion system was instrumented with thermocouples on all the key locations to allow flame position monitoring and to avoid flame attachment on the hardware. Further measurements included static pressure probes to monitor combustor pressure drop. The test was conducted in a systematic matrix format to include the most important combustion parameters in order to identify their individual effects on the combustion behaviors. The quantity of hydrogen in natural gas, fuel split, air preheat temperature, air reference velocity and flame temperature were the combustion related variables studied in the presented test campaign. The volumetric hydrogen quantity could be increased to 30% maintaining stable operation for all measured conditions. Higher hydrogen contents up to 80 vol-% were reached without flash back tendency. A glowing spark igniter prevented testing at even higher hydrogen contents. Hydrogen enriched gas showed higher NOx emissions and improved blowout limit. Hydrogen blending in the fuel also reduced the combustor pressure drop, lowered the prechamber temperature and raised the pilot tip temperature.

Abstract:
The newest Siemens gas turbine family has already been well received by the market. Nevertheless, the market drives continuing development of the family and the combustion system. Central focus is put on further increasing reliability and component lifetime and on increased inspection cycles, as well as increasing the engine power output and efficiency, which is directly linked to higher turbine inlet temperatures. Increasing attention, however, is given to the flexibility concerning fuel quality and according fluctuations. Additionally, more and more strict emission requirements must be considered. This paper especially reports on demonstration of the capability of the Siemens gas turbines with an annular combustion system to fulfil the requirements for the highest operational flexibility. Thus, the combustion system has been tested and qualified for the highest operating flexibility with special fuel requirements such as burning Naphtha, Light Oil #2 and Natural gas with an extremely wide range of heating values as well. Also special operation modes such as fuel changeover, fastest load changes for island grid operation, frequency response and load rejection require this highly flexible combustion system without any hardware exchange. In different frames when fired with natural gas, base load is reached with the NOx emissions ranging well below 25 ppmvd, confirming the high potential of this advanced hybrid burner. In liquid fuel operation, dry NOx emissions of 75ppmvd were demonstrated but by injecting fuel / water emulsion NOx emissions were reduced to below 42 ppmvd with different liquid fuel qualities. Combustion dynamics, unburned Hydrocarbons, CO and soot emissions remained always below the required limits.
