abstract: Planning efforts conducted during the early stages of a construction project, known as front end planning (FEP), have a large impact on project success and significant influence on the configuration of the final project. As a key component of FEP, front end engineering design (FEED) plays an essential role in the overall success of large industrial projects. The primary objective of this dissertation focuses on FEED maturity and accuracy and its impact on project performance. The author was a member of the Construction Industry Institute (CII) Research Team (RT) 331, which was tasked to develop the FEED Maturity and Accuracy Total Rating System (FEED MATRS), pronounced “feed matters.” This dissertation provides the motivation, methodology, data analysis, research findings (which include significant correlations between the maturity and accuracy of FEED and project performance), applicability and contributions to academia and industry. A scientific research methodology was employed in this dissertation that included a literature review, focus groups, an industry survey, data collection workshops, in-progress projects testing, and statistical analysis of project performance. The results presented in this dissertation are based on input from 128 experts in 57 organizations and a data sample of 33 completed and 11 on-going large industrial projects representing over $13.9 billion of total installed cost. The contributions of this work include: (1) developing a tested FEED definition for the large industrial projects sector, (2) determining the industry’s state of practice for measuring FEED deliverables, (3) developing an objective and scalable two-dimensional method to measure FEED maturity and accuracy, and (4) quantifying that projects with high FEED maturity and accuracy outperformed projects with low FEED maturity and accuracy by 24 percent in terms of cost growth, in relation to the approved budget. / Dissertation/Thesis / Doctoral Dissertation Construction Management 2019

A precise simulation requires a large amount of input data such as geometrical descriptions of the crystal structure, the external forces and loads, and quantitative properties of the material. Although some powerful applications already exist for research purposes, they are not widely used in education due to complex structure and unintuitive operation. To cater to the generic user base, a front-end application for material simulation software is introduced. With a graphic interface, it provides a more efficient way to conduct the simulation and to educate students who want to enlarge knowledge in relevant fields. We first discuss how we explore the solution for the front-end application and how to develop it on top of the material simulation software developed by mechanical engineering lab from Georgia Tech Lorraine. The user interface design, the functionality and the whole user experience are primary factors determining the product success or failure. This material simulation software helps researchers resolve the motion and the interactions of a large ensemble of dislocations for single or multi-layered 3D materials. However, the algorithm it utilizes is not well optimized and parallelized, so its performance of speedup cannot scale when using more CPUs in the cluster. This problem leads to the second topic on scientific computing, so in this thesis we offer different approaches that attempt to improve the parallelization and optimize the scalability.

This thesis presents the design, implementation and fabrication for a 0.13μm interface to a capacitive MEMS accelerometer. By varying the number of amplifier slices used in concurrence based on different full scale input ranges, the analog circuitry power scales as the input range scales. Due to the oversampling nature of typical accelerometer front ends, for a full-scale input increase of N times, the analog circuitry power reduces by N2 times. The front end has two signal amplification stages, with the first stage power scaled. The chip is 1.15mmx1.15mm and implemented in a 0.13μm CMOS process. The design was packaged with the MEMS accelerometer chip inside a 44 pin CQFP. Measured results show an output rms noise of 63μVrms in a 100Hz bandwidth. The total analog circuitry power scales very linearly with different full scale ranges. A novel simple offset removal network is also shown and confirmed via measurement results.

Este trabalho apresenta o desenvolvimento da eletrônica de front-end do Detector Neutrinos Angra. Esta eletrônica deve realizar o condicionamento dos sinais provenientes de tubos fotomultiplicados, visando fornecer ao sistema de aquisição de dados um pulso que facilite a identificação do fluxo de antineutrinos que passa pelo detector. Neste trabalho, as especificações do front-end foram definidas com base nos requisitos do experimento, que são: faixa linear de operação de 0 a 50 fótons; capacidade para identificar um fóton; duração do pulso menor do que alguns µs; largura de banda do pulso menor do que 60 MHz; excursão máxima na saída de até 2 V. Para isto, uma topologia do circuito de front-end foi proposta, sendo composta por quatro subsistemas: circuito de alimentação; circuito de condicionamento do sinal; circuito de controle de offset na saída e de limiar de tensão; e circuito discriminador. Oito módulos foram produzidos para equipar o detector. Neste trabalho, três módulos foram avaliados. Os testes mostraram que o desempenho dos três módulos atenderam as especificações, apresentando uma calibração média de 7,4±0,6 V/V , tempo de subida de 26±1 ns, tempo de descida de 81 ±2,5 ns, largura a meia altura de 74±1 ns, não-linearidade menor do que 2,2% para toda a faixa dinâmica de entrada e a saturação iniciando em aproximadamente 1,4 V. / The Neutrinos Angra Experiment aims to develop a compact detector and new techniques to measure the antineutrinos flow of nuclear reactions occurring inside the nuclear power plant reactors, allowing monitoring of its instant energy dissipation and revealing the composition of fissile nuclear fuel. This study presents the development of the Front-end electronics of the Neutrinos Angra detector. The electronics should perform the conditioning of the signals from photomultiplier tubes, aiming to provide a fast pulse for the data acquisition system whitch could facilitate the identification of the antineutrinos flow through the detector. In this work, the specifications of the front-end were defined based on the experiment requirements, which are: linear operating range 0-50 photons; ability to identify a single photon; the pulse duration less than a few µs; bandwidth of the pulse smaller than 60 MHz; maximum range in the output up to 2 V. For this, a topology of the front-end circuit has been proposed, consisting of four subsystems: power circuit; signal conditioning circuit; offset control circuit and discriminator circuit. Eight modules were produced to equip the detector. In this study three modules were evaluated. Tests showed that the performance of three modules met the specifications, with an average calibration of 7.4±0.6 V/V , rise time of 26 ±1 ns, falltime of 81 ±2.5 ns, width at half height of 74±1 ns, linearity better than 2.2% and saturation starting around 1.4 V.

Le travail de thèse porte sur l'étude de l'électronique front-end pour le télescope WFCTA (Wide Field of View Cherenkov Telescope Array,) qui est l'un des détecteurs de l’observatoire LHAASO (Large High Altitude Air shower Observatory,). Le manuscrit de thèse couvre six thèmes principaux allant de la simulation physique au développement d’un nouveau système d'acquisition de données.Tout d'abord, les principes de la physique des rayons cosmiques et de l'expérience LHAASO sont présentés donnant ainsi une introduction sur les sujets discutés dans la thèse. Des simulations ont été faites dans le but de comprendre la propagation des rayons cosmiques dans l'atmosphère et d’en déduire les caractéristiques du signal d'entrée de l'électronique. Ces simulations ont également été utilisées pour approfondir la compréhension des spécifications du télescope et de les vérifier.Un nouveau modèle de PMT a été élaboré pour être utilisé dans les simulations. Ce nouveau modèle est comparé aux autres modèles de PMT. Des modèles d’électronique pour les conceptions basées sur les composants électroniques classiques et sur l’ASIC (Application-specific Integrated Circuit) sont construites et étudiées. Ces deux solutions remplissent les spécifications du télescope WFCTA. Néanmoins, compte tenu du développement de la micro-électronique, il est proposé que l’électronique des télescopes de haute performance devrait être basée sur l’ASIC.L'ASIC sélectionné, PARISROC 2, est évalué en utilisant des bancs de tests existants. Les résultats montrent que ces bancs de tests ne peuvent pas démontrer pleinement la véritable performance de l’ASIC. Par conséquent, une carte électronique front-end prototype qui est basée sur ASIC a été conçu et fabriqué. Plusieurs modifications ont été apportées pour améliorer la performance de la nouvelle carte. Une description détaillée de ce développement est présentée dans la thèse. Un nouveau système d’acquisition de données a également été conçu pour améliorer la capacité de lecture de données dans le banc de tests de la carte front-end.Enfin, une série de tests ont été effectués pour vérifier le concept de design et pour évaluer la performance de la carte front-end. Ces résultats montrent la bonne performance générale de l'ASIC PARISROC 2 et que la carte front-end répond globalement aux spécifications de la WFCTA. Basé sur les résultats de ce travail de thèse, un nouveau ASIC, mieux adapté pour les télescopes de type WFCTA, a été conçu et est actuellement en cours de fabrication. / This thesis is focused on the study of the front-end electronics for the wide field of view Cherenkov telescope array (WFCTA), which is one of the large high altitude air shower observatory (LHAASO) detectors. The thesis manuscript covers six main topics going from the physics simulations to the implementation of a new data acquisition system. The physics of cosmic rays and the LHAASO experiment is presented giving foundation for discussion of the main topics of the thesis. Simulations were performed to understand the propagation of cosmic rays in the atmosphere and to determine the characteristics of the input signal of the electronics. These simulations allow also understand the specifications of the telescope and to verify them. A new PMT model was successfully built for both physical and electronic simulations. This new model is compared to other models and its performance is evaluated. Behavior models for the designs based on the classical electronics and application-specific integrated circuit (ASIC) were built and studied. It is shown that both solutions fit the requirements of the telescope. However, considering the development of the micro-electronics, it is proposed that the electronics of the high-performance telescopes should be based on ASIC. The selected ASIC, PARISROC 2, is evaluated by using the existing application boards. The results showed that the designs considered could not fully demonstrate the real performance of the chip. Therefore, a prototype front-end electronics board, based on PARISROC 2, was designed, implemented and fabricated. Several modifications and enhancements were made to improve the performance of the new design. A detailed description of the development is presented and discussed in the manuscript. Furthermore, a new data acquisition system was developed to enhance the readout capabilities in the front-end test bench.Finally, a series of tests were performed to verify the concept of the design and to evaluate the front-end board. The results show the good general performance of the PARISROC 2 and that this design globally meets the specifications of the WFCTA. Based on the results of this thesis work, a new ASIC chip, better adapted for telescopes such as WFCTA, has been designed and is currently being fabricated.

The diploma thesis on Development of Front-end Applications focuses on the design of computerization of enterprise processes covered by a unified front-end application. Exploratory research was used to suggest working methods to solve technological growth of the enterprise and how to evaluate business need of a front-end application. Later chapters present basic summary of development methodology used for automation of business processes. The diploma thesis innovatively proposes a role of a front-end specialist who does not need to create a program code and has closer relation to business departments. There are recommend analytical standards and development tools for automation of business processes as well as front-end implementation. Finally the work attaches a model example demonstrating relative simplicity and practical realization of new techniques for front-end application development. Powered by TCPDF (www.tcpdf.org)

International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / The world of data communication and networking has grown rapidly over the last decade, and this growth has been accompanied by the development of standards that reflect and facilitate the need for commercial products that work together in a reliable, robust, and coherent fashion. To a great extent this commercialization, with its increasing performance and diminishing cost, has not been adapted to the data communication needs of satellites. As budgets and mission development and deployment timelines shrink, space exploration and science will require the development of standards and the use of increasing amounts of off-the-shelf hardware and software for integrated satellite ground systems. The Renaissance project at NASA/Goddard Space Flight Center has engaged in rapid prototyping of ground systems using off-the-shelf hardware and software products to identify ways of implementing satellite ground systems "faster, better, cheaper". This paper presents various aspects of these activities, including issues related to the configuration and integration of current off-the-shelf products using telemetry databases for existing spacecraft, an analysis of issues related to the development of standard products for satellite communication, tradeoffs between hardware and software approaches to performing telemetry front-end processing functions, and proposals for future standards and development.
