Singapore's Mass Rapid Transit (MRT) network is one of the largest public works projects undertaken by the Singapore government. This thesis summarizes and evaluates the performance of Tunnel Boring Machine (TBM) construction in Singapore's MRT network. Surface settlement induced by the tunneling process can cause damage to underground utilities and foundations and buildings and/or disrupt daily life by damaging roads and pavements, and is used in this thesis as a measure of performance. The influence of encountered geology and adopted construction methods (referring to the type of TBM used) on settlement is discussed. The dominant construction method on all four existing MRT lines involved the use of shield TBMs, with the main difference being the method of face support adopted. The North-South East-West (NS-EW) line employed largely compressed air as face support, while a move towards greater use of Earth Pressure Balance (EPB) was observed on the North-East line (NEL) and Circle Line (CCL). The use of EPB on the NEL resulted in 22 incidences of large, localized ground losses, which were of two types; 1. subsurface voids, or voids which formed above the tunnel face but were grouted before they could migrate to the surface, 2. surface sinkholes, or local depressions which were found by visual inspection to appear over the tunnels as the machine advanced. These large, localized ground losses usually occurred when tunneling through different weathering grades within a single formation or through mixed faces of different geological formations. The variability in ground conditions which resulted from these mixed weathering grades and mixed faces is a direct result of extensive tropical weathering of Singapore's soils, and poses a challenge to the performance of EPB machines during construction. The employment of slurry machines on the CCL was intended to mitigate some of the difficulties faced by EPB machines on the NEL, though with limited success. The use of slurry machines on the CCL resulted in the additional problem of slurry discharging to the surface and disrupting traffic. Given Singapore's plans to double the length of her rail network by 2030, the need to understand the impact of construction projects on adjacent structures and surface activities remains just as important, if not more so.

Full textTrellis-Coded Modulation (TCM) is employed with quadrature amplitude modulation (QAM) to provide error correction coding with no expense in bandwidth. There are two common implementations of TCM, namely pragmatic TCM and Ungerboeck TCM. Both schemes employ Viterbi algorithms for decoding but have different code construction. This thesis investigates and compares the performance of pragmatic TCM and Ungerboeck TCM by implementing the Viterbi decoding algorithm for both schemes with 16-QAM and 64-QAM. Both pragmatic and Ungerboeck TCM with six memory elements are considered. Simulations were carried out for both pragmatic and Ungerboeck TCM to evaluate their respective performance. The simulations were done using Matlab software, and an additive white Gaussian noise channel was assumed. The objective was to ascertain that pragmatic TCM, with its reduced-complexity decoding, is more suitable to adaptive modulation than Ungerboeck TCM.

Full textThe remote sensing industry is experiencing an unprecedented rush of activity to deploy commercial and scientific satellites. NASA and its international partners are leading the scientific charge with The Earth Observation System (EOS) and the International Space Station Alpha (ISSA). Additionally, there are at least ten countries promoting scientific/commercial remote sensing satellite programs. Within the United States, commercial initiatives are being under taken by a number of companies including Computer Technology Associates, Inc., EarthWatch, Inc., Space Imaging, Inc., Orbital Imaging Corporation and TRW, Inc. This activity is due to factors including: technological advances which have lead to significant reductions in the costs to build and deploy satellites; an awareness of the importance of understanding human impact on the ecosystem; and a desire to collect and sell data some believe will be worth $1.5 billion (USD) per year within five years. The success and usefulness of these initiatives, both scientific and commercial, depends largely on the ease and cost of providing remotely sensed data to value added resellers and end-users. A number of these spacecraft will provide an interface directly to users. To provide these data to the largest possible user base, ground station equipment must be affordable and the data must be distributed in a timely manner (meaning seconds or minutes, not days) over commercial network and communications equipment. TSI TelSys, Inc. is developing ground station equipment that will perform both traditional telemetry processing and the bridging and routing functions required to seamlessly interface commercial local- and wide-area networks and satellite communication networks. These products are based on Very Large Scale Integration (VLSI) components and pipelined, multi-processing architectures. This paper describes TelSys’ product family and its envisioned use within a ground station.

Full textThis paper is an ethnographic study of the social practices that make the creation processes of meanings and links with the Harley-Davidson brand visible by the riders that attended the rides of the H.O.G - Harley Owners Group - in São Paulo city between May 2009 and February 2011. I try to understand the dimensions of brand involvement by combining the participant observation techniques, interviews and image analysis. This thesis presents an analysis of the H.O.G. organization in São Paulo city and follows the movement of the riders in order to identify the relations that are formed among them and between the riders and the brand. Through the use of film images it is possible to identify the constitution of a frame of reference which inspires the performance of the riders who participate in weekly rides. In this universe the importance of the images is reinforced by the photographs, a common practice in the events and that helped to identify what is understood as Harley Style and the deriving category the harleyro. Belonging to the group is the result of the articulation of several elements that involve the aestheticization of the motorcycle and the rider. Some aspects chosen and shared by the group characterize a hegemonic masculinity that guides the behavior, discourse and the brand consumption experience. I finish this paper reflecting on the concept of brand and the links created with it.

Full textThe most widely used protocol for providing reliable service and congestion control in the Internet is the Transmission Control Protocol (TCP). When the Internet is moving towards more use in mobile applications it is getting more important to know how TCP works for this purpose.
One of the technologies used for mobile Internet is the Enhanced General Packet Radio Service (EGPRS) extension to the popular GSM system. This thesis presents a low-level analysis of TCP performance in an EGPRS system and an overview of existing TCP, GSM and EGPRS technologies.
The bottleneck in an EGPRS system is the wireless link – the connection between the mobile phone and the GSM base station. The data transfer over the wireless link is mainly managed by the complex RLC/MAC protocol.
In this thesis, simulations were made to identify some problems with running TCP and RLC/MAC together. The simulations were made using existing EGPRS testing software together with a new TCP module. The simulation software is also briefly described in the thesis.
Additionaly, some suggestions are given in order to enhance performance, both by changing the EGPRS system and by modifying the TCP algorithms and parameters.

Full textThe purpose of this thesis is threefold. Firstly, to attempt to provide validity for the two-sided matching process; secondly, analyze FITREP attributes to determine their suitability for a weighted criteria evaluation system and; thirdly, compare the USMC promotion and assignment process with contemporary human resource management practices. Using data from the USMC Officer Accession Career file (MCCOAC), a logit model is used to estimate the effects of TBS preference and other officer characteristics on retention to the seven year mark. Findings indicate that there was little difference in the probability of retention throughout most preference levels except for the bottom sixth. Using USMC FITREP data, an ordinary least squares model is used to estimate the effects of rank and MOS on FITREP scores across all attributes. Multiple comparison tests demonstrated that there are statistical differences at the 0.05 level between the means of the MOSs. Additionally, reporting creep is continuing across all attributes. Surveys were also conducted. The first survey indicated that USMC officers believe the FITREP attributes were not all equally important within, and across each MOS - although the USMC assesses them as such. The second survey indicated that the USMC promotion and assignment process can be strengthened through a clearly defined HRM plan that extends beyond 'faces' and 'places', and provides very clear links to the organizational strategy. Based on the findings it is recommended that the USMC review its HRM processes and conduct further analyses on the FITREP data for: (1) correlation, (2) longitudinal analysis as a predictor for success and, (3) relevance and relationship to MOS characteristics, position descriptions, and organizational strategy.

Full textSecondary ion mass spectrometry (SIMS) instruments need to be improved in order to satisfy the demands of trends in many fields that require analytical tools that can map samples with both excellent resolution and high-sensitivity chemical information, but also with shorter time of analysis. The objectives of this thesis are: investigate the enhancement of the mass resolution of double focusing mass spectrometers by replacing the standard spherical sector with a novel spheroid geometry which has better focusing properties, and to investigate the reduction of the time of analysis in imaging SIMS by the proof-of-concept of the SIMS multi-ion- beam system.A comparison of the main focusing properties of the spherical sector, the spheroid geometry and a hybrid spheroid geometry, was made using the SIMION software. A comparison in a Nier-Johnson configuration between the spherical sector and the spheroid, showed that the beam presents a rotation of 90° at the exit of the magnet harming the mass resolution in the spheroid configuration. By adding an electrostatic element that can rotate the beam 90° the performance of the mass spectrometer could be improved. However, a comparison of the performances between the spherical and hybrid sectors simulated in a Mattauch-Herzog configuration, showed that when the double focusing condition is properly satisfied, better mass resolution could be achieved with the spheroid geometry.A multi-ion-beam system was investigated for SIMS analysis. A simulation through the secondary optics of a Cameca IMS XF showed successful transmission of nine beams through the optics resulting in nine well focussed spots on the multi channel plate (MCP) detector. The proof-of-concept was completed experimentally in the Cameca IMS 6F, where a multi-hole aperture was mounted in the primary column generating 9 and 16 beams of sizes between 4 μm to 10 μm. Images of an AlCu grid were obtained when t the multi-ion-beam system was scanned over the sample. These results showed that the multi-ion-beam system is a feasible technique for imaging SIMS and by optimizing the design multi-nano-ion-beams will be a solution for reducing drastically the time of analysis

Full textThanks to digital technology, many devices have appeared in classrooms and offer the possibility of multiplying teaching aids in the teaching / learning process. The interactive whiteboard (TBI / TNI) is one of them. Thus, it seems judicious to question the factors that influence the effect of such a device on school performance, given the contradictory results of scientific studies on the subject.This doctoral research work is a mixed research, combining both quantitative and qualitative data. As a result of the literature review, she tries to answer the following question: What are the factors that influence the impact of the use of the Interactive Whiteboard (IWB) on student performance?Prior to the implementation of experimental research, initial assumptions assumed that in an interactive whiteboard-mediated teaching / learning process, students' academic performance is influenced by the student's learning style of learning. on the one hand, and on the other, that it is a function of their degree of motivation with regard to the interactive whiteboard.In order to compare these above-mentioned hypotheses with the reality on the ground, a two-phase experimental procedure consisting of a teaching / learning situation without the interactive whiteboard and then with the interactive whiteboard was conducted in order to measure student academic performance.To collect the data, the tools that are the questionnaire, a test of identification of the learning style according to the model VAK (Visual, Auditory, Kinesthetic), the semi-directed individual interviews, a scale of motivation and observations in situ have been used.Following the analysis of the results obtained from the nonparametric alternatives of the Khi2 test and Student's t test for paired samples, significant differences are observed in the performance of visual learning style students, unlike students with other major learning styles.The impact of the intervention of the whiteboard in the teaching-learning process would also depend on the student's gender and motivation towards the whiteboard. Indeed, we find that male students and students with a self-determined motivation for the technological tool have seen their performance increase significantly

Full textSiemens Industrial Turbomachinery AB is interested in digitizing their current work processes. Therefore, the reason for this study is to examine if AR performs better than paper as an instruction method for operators at Siemens in Trollhättan. In order to answer the question "How well does Augmented Reality (AR) technology perform compared to physical papers as an instruction method for operators in a production environment?", two qualitative methods have been applied. Data was collected by using observations and semi-structured interviews for the analysis of this study. Our choice of theoretical framework was not only applied for evaluating the performance, but also the operators' willingness to adopt AR as a form of instruction method. The findings from the results show that AR performs better as an instruction method and that the operators had a positive attitude when using AR. However, it is still unclear how well this technology will be accepted. This is mainly due to the fact that future improvements still need to be made to the hardware and the lack of customized applications for the operators' needs.

The aim of this study is to identify the relationship between firm value and performance and executive remuneration. In general, the literature suggests that firms with executive higher remuneration tend to have better value and performance in comparison with companies with lower remuneration. We analyze a unique Brazilian database to test this hypothesis. The analysis of 420 Brazilian companies from 2002 to 2009 indicates a positive and significant relation between executive remuneration and firm value (price-to-book), suggesting that companies that pay better executive remuneration have higher value. On the other hand, there is no significant relation between executive remuneration and operational performance (ROA and sales growth).
Este trabalho tem como objetivo identificar se a remuneração dos executivos afeta o valor e desempenho das empresas. Em geral, a literatura sugere que companhias que melhor remuneram seus administradores tendem a apresentar um valor e desempenho superior. Utilizando dados inéditos no Brasil, este trabalho procura testar essa hipótese. A análise de 420 companhias abertas brasileiras no período de 2002 a 2009 indica que existe uma relação positiva e significativa entre remuneração executiva e valor da empresa (price-to-book), ou seja, empresas que pagam mais a seus executivos possuem maior valor de mercado. Por outro lado, não existe evidência significativa que empresas que melhor remuneram seus executivos apresentam um melhor desempenho operacional (retorno sobre ativos e crescimento de vendas).
