The rapid development of nanotechnology has created a need for advanced nanohandling tools and techniques. One active branch of research in this area focuses on the use of microrobots for automated handling of micro- and nanoscale objects. 'Automated Nanohandling by Microrobots' presents work on the development of a versatile microrobot-based nanohandling robot station inside a scanning electron microscope (SEM). The SEM serves as a powerful vision sensor, providing a high resolution and a high depth of focus, allowing different fields of application to be opened up. The pre-conditions for using an SEM are high-precise, user-friendly microrobots which can be integrated into the SEM chamber and equipped with application-specific tools. 'Automated Nanohandling by Microrobots' introduces an actuation principle for such microrobots and presents a new robot design. The book also introduces the concept of the robot station inside an SEM, along with the station's control system. Different aspects of this research field regarding the hardware and software implementation of the system components, including the sensory feedback for automated nanohandling, are discussed in detail. Images of the robot and its endeffector, as well as of the objects to be handled, are used as visual feedback by the automatic control system of the robot station. Extensive applications of the microrobot station for nanohandling, nano-characterisation and nanostructuring are provided, together with the experimental results. In addition, the use of an atomic force microscope as a nanohandling robot is investigated. Based upon the Microrobotics course for students of computer sciences and physics at the University of Oldenburg, Automated Nanohandling by Microrobots provides the practicing engineer and the engineering student with an introduction to the design and applications of robot-based nanohandling devices. Those unfamiliar with the subject will find the text, which is complemented throughout by the extensive use of illustrations, clear and simple to understand.

Middleware provides an integration framework for multiple and potentially - verse computing platforms. It allows developers to engineer distributed appli- tions more easily, providing abstractions and primitives to handle distribution and coordination. Middlewareisconstantlyfacingnewchallenges.Today&#8217;sadvancesincomp- ing, including development of pervasive applications, exacerbates the diversity problem, introducing variations not only in terms of performance, but also in terms of environments and device characteristics. Software engineers are the- fore challenged both in the area of the development of new and scalable m- dleware systems, where open, heterogeneous, component-based platforms should provide richer functionality and services, and in the area of application devel- ment, where tools to simplify the use of middleware solutions are necessary. Software Engineering and Middleware is the premier workshop for the - search and practice community of software engineering working in both areas to presentanddiscussnewideasinthis?eld.SEM2004wasthefourthinternational workshop on software engineering and middleware of the EDO/SEM workshop series. Previous workshops of this series were successfully held in 2002, 2000 and 1999. Most of the proceedings have been published by Springer in the Lecture Notes in Computer Science series.

With the development of technology and industries, newer materials such as Tungsten, Molybdenum etc. and various other Super Alloys and Ceramics have been developed which are being widely used in nuclear engineering, aerospace and various other industries because of their hardness, heat resistance qualities and high strength to weight ratio. Machining of these hard materials is very difficult by conventional machining processes. Therefore non-conventional machining processes have been developed for the machining of such type of materials. The Objective of this work is mainly to study the effect of various input parameters like Electrode material, Discharge Current, Gap Voltage, Pulse-On Time, Pulse-Off Time on the various output parameters like MRR, TWR and Surface roughness. In this study, these output parameters are studied by using the Taguchi's Design of Experiments through Minitab software. Using this software, Means and S/N ratios for all the output parameters were calculated. Micro structure was also observed using SEM machine.
This study presents the comparison of microstructure and mechanical properties of SS-316 Stainless steel and SA-2062 alloys welded by TIG and MIG welding processes. Microstructures of base metal and weld metal were studied with SEM and EDAX software. Mechanical properties like tensile strength and micro hardness have also been evaluated. During research work it is investigated that the average tensile strength of weld joint with TIG welding is comparatively less than that of joint with MIG welding. Micro hardness of TIG welding is relatively more than that of MIG welding. The minimum HAZ is found directly proportional to maximum tensile strength. More coarse dimples are seen in TIG joints as compared to MIG joints. The dimple size exhibits a directly proportional relationship with strength and ductility, i.e. if the dimple size is finer, then the strength and ductility of the respective joint will be higher and vice versa. The higher hardness at weld interface may be due to enrichment of this zone with FE, Ni, and Cr and subsequent formation.

The output of this research is framework that informs the adoption of Software as a Service (SaaS) for Small and middle-sized businesses (SMEs). Recent research has shown that there are significant advantages of SaaS when adopted by SMEs. The author investigated SMEs in different sectors on a weighting proposal. This target was 87% in excess of the required minimum of 200 respondents as required by Structural Equation Modeling (SEM) which was done using SPSS AMOS focused on modeling, trimming and best fit. However 293 respondents were obtained, which was significantly above the minimum requirement. The findings indicated that the factors that significantly influence the adoption of SaaS by SMEs include: awareness, trust, prior IT experience, relative advantage, triability, ICT knowledge and skills, top level management support and complexity. The researcher was able to recommend firstly, that evaluation of the market is critical for SaaS deployment and finally, that application developers, technological consultants, software vendors, and policy makers that intend to adopt SaaS should consider the extended TOE model developed from this research.
This thoroughly revised and updated Fourth Edition of a time-honored text provides the reader with a comprehensive introduction to the field of scanning electron microscopy (SEM), energy dispersive X-ray spectrometry (EDS) for elemental microanalysis, electron backscatter diffraction analysis (EBSD) for micro-crystallography, and focused ion beams. Students and academic researchers will find the text to be an authoritative and scholarly resource, while SEM operators and a diversity of practitioners &#8212; engineers, technicians, physical and biological scientists, clinicians, and technical managers &#8212; will find that every chapter has been overhauled to meet the more practical needs of the technologist and working professional. In a break with the past, this Fourth Edition de-emphasizes the design and physical operating basis of the instrumentation, including the electron sources, lenses, detectors, etc. In the modern SEM, many of the low level instrument parameters are now controlled and optimized by the microscope&#8217;s software, and user access is restricted. Although the software control system provides efficient and reproducible microscopy and microanalysis, the user must understand the parameter space wherein choices are made to achieve effective and meaningful microscopy, microanalysis, and micro-crystallography. Therefore, special emphasis is placed on beam energy, beam current, electron detector characteristics and controls, and ancillary techniques such as energy dispersive x-ray spectrometry (EDS) and electron backscatter diffraction (EBSD). With 13 years between the publication of the third and fourth editions, new coverage reflects the many improvements in the instrument and analysis techniques. The SEM has evolved into a powerful and versatile characterization platform in which morphology, elemental composition, and crystal structure can be evaluated simultaneously. Extension of the SEM into a 'dual beam' platform incorporating both electron and ion columns allows precision modification of the specimen by focused ion beam milling. New coverage in the Fourth Edition includes the increasing use of field emission guns and SEM instruments with high resolution capabilities, variable pressure SEM operation, theory, and measurement of x-rays with high throughput silicon drift detector (SDD-EDS) x-ray spectrometers. In addition to powerful vendor- supplied software to support data collection and processing, the microscopist can access advanced capabilities available in free, open source software platforms, including the National Institutes of Health (NIH) ImageJ-Fiji for image processing and the National Institute of Standards and Technology (NIST) DTSA II for quantitative EDS x-ray microanalysis and spectral simulation, both of which are extensively used in this work. However, the user has a responsibility to bring intellect, curiosity, and a proper skepticism to information on a computer screen and to the entire measurement process. This book helps you to achieve this goal. Realigns the text with the needs of a diverse audience from researchers and graduate students to SEM operators and technical managers Emphasizes practical, hands-on operation of the microscope, particularly user selection of the critical operating parameters to achieve meaningful results Provides step-by-step overviews of SEM, EDS, and EBSD and checklists of critical issues for SEM imaging, EDS x-ray microanalysis, and EBSD crystallographic measurements Makes extensive use of open source software: NIH ImageJ-FIJI for image processing and NIST DTSA II for quantitative EDS x-ray microanalysis and EDS spectral simulation. Includes case studies to illustrate practical problem solving Covers Helium ion scanning microscopy Organized into relatively self-contained modules &#8211; no need to 'read it all' to understand a topic Includes an online supplement&#8212;an extensive 'Database of Electron&#8211;Solid Interactions'&#8212;which can be accessed on SpringerLink, in Chapter 3
This project is an approach towards the synthesis and characterization of liquid Gallium filled Indium Oxide nanothermometer by using resistive chemical vapor deposition technique. All the measurements and microscopical studies has been presented by using the concepts of different microscopies like XRD/SEM/EDX/HRTEM and related sample characterization software like Pcpdfwin (XRD-Analysis), Origin (Plotting graphs), Image Tool (SEM Images Analysis) and Digital Micrograph (TEM/HRTEM Images Analysis). The growth methods such as resistive heating chemical vapor deposition (RH-CVD) and growth mechanisms such as vapor-liquid-solid (VLS) and vapor solid (VS) of growing nanotubular structures have been discussed in this report. The HRTEM-EDX measurement along the radial direction of an Indium Oxide nanotubular structure explore the in depth knowledge of the flow of liquid Gallium. These similar observations have not been reported by other authors. The synthesis of metal filled Oxide nanotubular structures may have potential applications in future nanofluid devices. It could be ideal for the semiconductor industry and bio medical fields.

Studienarbeit aus dem Jahr 2008 im Fachbereich Informatik - Wirtschaftsinformatik, Note: 1,0, FOM Hochschule für Oekonomie & Management gemeinnützige GmbH, München früher Fachhochschule, 20 Quellen im Literaturverzeichnis, Sprache: Deutsch, Abstract: Ein Hauptproblem unternehmerischer Tätigkeit besteht darin, dass die Zukunft nur sehr schwer vorhersehbar ist. Die Prognosen der Umweltveränderungen auf Grund neuer Technologien, neuer Märkte, gewandelter Verhaltensweisen der Abnehmer und Konkurrenten sowie staatlicher Eingriffe stellen daher eines der grössten Managementprobleme dar. Die Entscheidungssituation ist in den letzten Jahren zunehmend komplexer geworden. Durch die Internationalisierung der Märkte nehmen nicht nur die möglichen Handlungsalternativen massiv zu, sondern auch deren Konsequenzen. Entscheidungen, die heute getroffen werden, wirken sich auf eine Vielzahl von Prozessen aus, die nur schwer vorherzusehen sind. Auch wenn die Unternehmensumwelt sehr komplex ist, müssen Entscheidungen getroffen werden, nicht nur für das operative Geschäft, sondern vor allem für die Zukunft. Strategische Planung ist in der betrieblichen Praxis, speziell in mittleren und kleinen Betrieben, eher die Ausnahme. Circa 95% aller Unternehmen in Deutschland planen ihre Zukunft ohne strategische Instrumente und Methoden. Eine derartige Planung wäre empfehlenswert, um den zunehmenden unspezifischen Risiken und Chancen der Umwelt entgegenwirken zu können. Viele Unternehmen scheitern an einer unzureichenden und unterlassenen strategischen Planung. Demnach ist die mangelnde Planung und entsprechende Fehleinschätzungen der anfallenden Kosten, des Investitionsbedarfs sowie der Nachfrageentwicklung und der Konkurrenzsituation mit über 60% Hauptursache für eine spätere Unternehmensaufgabe bzw. einen Konkurs. Eine strategische Planung sensibilisiert die Einstellung der Unternehmung auf künftige Risiken und Chancen, so dass demzufolge alternative Zukunftsentwicklungen im Vorfeld erkannt und darauf reagiert werden kann. Um einen Einblick in die Unternehmensplanung zu bekommen, wird diese im folgenden zuerst beschrieben und anschliessend die Software Strategic Enterprise Management (SEM) der Firma SAP Deutschland AG und dessen Module zur strategischen Unternehmensplanung vorgestellt.
