Due to the rapid technological developments in the car industry and the high quality demands of customers, manufacturers and researchers focus on the reduction of surface roughness making use of various surface topography measurement systems. This master thesis focuses on development of a waviness measurement system (WMS) at Volvo Cars where light from different heights and angles illuminates the surface of an extended object in order to acquire images with different intensities due to shadowing effect and reflection. With this, surface irregularities and imperfections can be detected both in polished and unpolished surfaces for improving the car panels in the manufacturing process.  The initial WMS idea was to illuminate the surface at different heights from the four corners of a dark room using 20 flash lights and a camera positioned exactly on the top of the surface in the middle of the room. The first light goes on and the image is acquired. This procedure continues for all flash lights in 19s.The acquired images were evaluated by Matlab application. With the new WMS system flash lights are replaced by 32 RGB COB LED lights using the DMX512 protocol to communicate with them. The system runs in 9s which is half the time of the old WMS system. New LabView and Matlab codes were adjusted to the new parameters and devices. In the end, measurements were taken with different surfaces, exposure times and color lights. Details of the new devices and software are analyzed in this thesis.

This Thesis project is a part of the research conducted in Solar industry. ABSOLICON Solar Concentrator AB has invented and started production of the prospective solar concentrated system Absolicon X10. The aims of this Thesis project are designing, assembling, calibrating and putting in operation the automatic measurement system intended to evaluate distribution of density of solar radiation in the focal line of the concentrated parabolic reflectors and to measure radiation from the artificial source of light being a calibration-testing tool.On the basis of the requirements of the company’s administration and needs of designing the concentrated reflectors the operation conditions for the Sun-Walker were formulated. As the first step, the complex design of the whole system was made and division on the parts was specified. After the preliminary conducted simulation of the functions and operation conditions of the all parts were formulated.As the next steps, the detailed design of all the parts was made. Most components were ordered from respective companies. Some of the mechanical components were made in the workshop of the company. All parts of the Sun-Walker were assembled and tested. The software part, which controls the Sun-Walker work and conducts measurements of solar irradiation, was created on the LabVIEW basis. To tune and test the software part, the special simulator was designed and assembled.When all parts were assembled in the complete system, the Sun-Walker was tested, calibrated and tuned.

A novel technique by employing a capacitance displacement measurement system to measure the post-weld-shift (PWS) caused by laser welding in the butterfly-type laser diode module packaging process is proposed. Reduction of the PWS is an important issue in developing low-cost and high-performance semiconductor laser module. Prior to the reduction and compensation of the PWS, a measurement system of PWS must be constructed. In comparison to the high-magnification camera with image capturing system (HMCICS) limited in resolution of 0.07£gm due to its pixels, a measurement system with a higher resolution of 0.0254£gm is used. During the measurement procedure, the PWS of the ferrule probed by the sensors is converted into the fiber misalignment shifts. The coupling efficiency can be improved over 70% after compensation. The result indicates that the PWS can be qualitatively measured and quantitatively computed.

The purpose of this project is to create a measurement system aimed for a laboratory environment at Uppsala University. The measurement system will be used by students for laboratories of electrical science. It will include a measurement station and an application that will be used by the students.  A specification of 16 channels of measuring data, 8 current and 8 voltage, was given by the client. Beside this specification there were 8 others to fulfil. The measurement station is connected to a compactRIO which will enable the possibility to graphically and numerically represent the results through an application created in Labview. The application will include time and phasor representations of both current and voltage. It will also include two power vectors for 6 channels each. The result of this project is a fully working measurement system which generates a good overview of measurements made on an electrical power system. All given specifications was fulfilled except one, which was not possible to achieve with the chosen methodology.

Along with economical globalization, several performance measurement models begin to appear and companies in general are brought to invest in the search for the model that better fits each one s purpose. The effort is focused in the development, implementation and use of performance measurement systems. Among a number of proposed models, the one that gained more recognition worldwide was BSC. This fact itself does not guarantee the full use of the performance measurement system. Employee s participation and commitment has been an issue that deserves attention from researchers because it is an unquestionable fact that its involvement increases the performance of the individual and improves the motivation of the group. For this research it was chosen the action-research method, due to the fact of it to allow researchers to play an active role in the very reality of observed facts. The research had the support of large bibliographic studies to identify and evaluate influent factors to development and evolution of SMD. During action-research work, questionnaires were applied, interviews were conducted and thoughts were made about the adopted actions and results achieved. As a final result of field research, a better understanding of process change, skill development in the use of SMD, system management and involvement of stakeholders were achieved. Recommendations resultant of this research included managers, quality management staff and executives of the company, the development of employees, the improvement of SMD use, ownership and continuous improvement of the business. / O objetivo precípuo desta dissertação é buscar formas para aumentar a participação dos funcionários no desenvolvimento e uso do sistema de medição de desempenho em uma empresa de bens de capital.

International Telemetering Conference Proceedings / October 25-28, 1993 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Information management is of essential importance during design and operation of flight test measurement systems to be used for aircraft airworthiness certification. The reliability of the data generated by the realtime- and post-processing processes is heavily dependent on the reliability of all provided information about the used flight test measurement system. Databases are well fitted to the task of information management. They need however additional application software to store, manage and retrieve the measurement system configuration data in a specified way to support all persons and aircraft- and ground based systems that are involved in the design and operation of flight test measurement systems. At the Dutch National Aerospace Laboratory (NLR) a "Measurementsystem Configuration DataBase" (MCDB) is being developed under contract with the Netherlands Agency for Aerospace Programs (NIVR) and in cooperation with Fokker to provide the required information management. This paper addresses the functional and operational requirements to the MCDB, its data-contents and computer configuration and a description of its intended way of operation.

This research investigates Destination Management Organisation (DMOs) in China, and looks at their functions and their adoption of Performance Measurement Systems (PMSs). A two-stage questionnaire survey has adopted to achieve the pre-determined aims of the research. Finally, ninety-three DMOs took part in the first stage survey and thirty-four DMOs were involved in the second stage survey. The key findings from the research are as follows. (1) Irrespective of their nature and level, Chinese DMOs attached most importance to the functions of “economic-driver”, “marketing” and “coordination & collaboration”. (2) DMOs attached a second level of importance to the functions of “operator”, “administrator”, “statistics” and “training”; however, particularly at municipality and city levels; also Chinese public DMOs paid more attention to these aspects. (3) Chinese public DMOs, particularly at provincial and city level, placed more emphasis on the functions of “regulator” and “legitimacy”. (4) Chinese higher-level public DMOs paid less attention to the function of “public awareness”, “funding” and “international relations”, however they did performed much better than non-public lower-level DMOs to these tasks. (5) Chinese governmental DMOs at higher-level, and private DMOs, were the best at adopting PMSs in their organisations. (6) The PMSs of Chinese DMOs paid greatest attention to measuring the aspects of “visitor”, “earning” and “marketing”, and medium levels of attention to the aspects of “stakeholder”, “operation” and “event”, and relatively low attention to evaluating their performance of the aspects of “employment” and “innovation” in their organisations. Finally, a refined PMS model that could be adopted by Chinese DMOs in the future was developed at the end. Based on the above findings, the refined model aimed to measure the performance of “stakeholders”, “employees” and “customers” by assessing the outcomes of the aspects of “management” and “marketing” for Chinese DMOs. The refined PMS model was developed and based on the top-down operation system that currently existed in China and was supposed to pursue every major aspect of the system for each stakeholder in the DMOs.

Although the research in the field of the performance measurement system for remanufacturing activities is partial, an amount of literature and research has been performed regarding the performance measurement applicable for remanufacturing activities. The success of applying a performance measurement system on Remanufacturing relies on the relationship and inclusion of all perspectives; from customers to financial, as well as the remanufacturing process, and all challenges facing a remanufacturing process. Since the retrieval of used products is essential to the remanufacturers, the successful management of those specific processes contributes to an effective and efficient outcome of a Remanufacturing business’s performance outcome.

Cell mechanics are directly related to the biological functionality of a cell, and therefore have been extensively studied. Current understanding of the unique relationships associated with mechanical loading conditions and the biological outcomes of a cell is far from complete [1]. The main objective of this thesis work was the design of a device capable of determining mechanical properties including stiffness and Young’s modulus of a biological cell. The device was implemented using micro-electro mechanical systems technology (MEMS), and the cell testing was limited to yeast cells for the purpose of this research. The design consisted of a micro-gripper which performed controlled cell squeezing with a spring of known stiffness. Differential displacements were obtained allowing for the calculation of cell mechanical properties. The incorporation of spatially periodic structures on the moving components of the gripper enabled measurements with 10 nm precision based on discrete Fourier transformation and phase [2].
