The focus of this thesis is to explore and quantify the response of large-scale solid mass transfer events on satellite-based gravity observations. The gravity signature of large-scale solid mass transfers has not been deeply explored yet; mainly due to the lack of significant events during dedicated satellite gravity missions‘ lifespans. In light of the next generation of gravity missions, the feasibility of employing satellite gravity observations to detect submarine and surface mass transfers is of importance for geoscience (improves the understanding of geodynamic processes) and for geodesy (improves the understanding of the dynamic gravity field). The aim of this thesis is twofold and focuses on assessing the feasibility of using satellite gravity observations for detecting large-scale solid mass transfers and on modeling the impact on the gravity field caused by these events. A methodology that employs 3D forward modeling simulations and 2D wavelet multiresolution analysis is suggested to estimate the impact of solid mass transfers on satellite gravity observations. The gravity signature of various submarine and subaerial events that occurred in the past was estimated. Case studies were conducted to assess the sensitivity and resolvability required in order to observe gravity differences caused by solid mass transfers. Simulation studies were also employed in order to assess the expected contribution of the Next Generation of Gravity Missions for this application.

Students reflect more on their learning in course subjects when they participate in managing their teaching–learning environment. As a form of guided participation, peer assessment serves the following purposes: (a) it improves the student’s understanding of previously established learning objectives; (b) it is a powerful metacognitive tool; (c) it transfers to the student part of the responsibility for assessing learning, which means deciding which learning activities are important and choosing the degree of effort a course subject will require; (d) it emphasizes the collective aspect of the nature of knowledge; and (e) the educational benefits derived from peer assessment clearly justify the efforts required to implement activities. This paper reports on the relative merits of a learning portfolio compiled during fine arts-related studies in which peer assessment played an important role. The researchers analyzed the student work load and the final marks students received for compulsory art subjects. They conclude that the use of a closed learning portfolio with a well-structured, sequential and analytical design can have a positive effect on student learning and that, although implementing peer assessment may be complex and students need to become familiar with it, its use is not only feasible but recommendable.

Research on intergenerational transmissions of poverty and inequality has tended to focus on material transfers. This paper refocuses attention on the intersection of material and psychosocial transfers, which reveals temporal and gendered complexities. It examines three key ideas emerging from the life course literature (relationality, intersectionality and intergenerationality) to shed light on how these complexities might be addressed. It is argued that a human wellbeing lens is potentially useful as a unifying framework to integrate these ideas as it interrogates what living well means over the life course and how it is constructed relationally.

The work of cataloging and digitizing the Historical Ar-chive of the Prelature of Humahuaca, presents us with documen-tary mass, almost unused for historical research. Due to organiza-tional reasons, this documentary heritage was limited to consulta-tion of researchers. The development of “Documenta” project will allow us to know the contents of that file, get closer to these do-cuments for consultation and scientific production.

SD card (Secure Digital Memory Card) is widely used in portable storage medium. Currently, latest researches on SD card, are mainly SD card controller based on FPGA (Field Programmable Gate Array). Most of them are relying on API interface (Application Programming Interface), AHB bus (Advanced High performance Bus), etc. They are dedicated to the realization of ultra high speed communication between SD card and upper systems. Studies about SD card controller, really play a vital role in the field of high speed cameras and other sub-areas of expertise. This design of FPGA-based file systems and SD2.0 IP (Intellectual Property core) does not only exhibit a nice transmission rate, but also achieve the systematic management of files, while retaining a strong portability and practicality. The file system design and implementation on a SD card covers the main three IP innovation points. First, the combination and integration of file system and SD card controller, makes the overall system highly integrated and practical. The popular SD2.0 protocol is implemented for communication channels. Pure digital logic design based on VHDL (Very-High-Speed Integrated Circuit Hardware Description Language), integrates the SD card controller in hardware layer and the FAT32 file system for the entire system. Secondly, the document management system mechanism makes document processing more convenient and easy. Especially for small files in batch processing, it can ease the pressure of upper system to frequently access and process them, thereby enhancing the overall efficiency of systems. Finally, digital design ensures the superior performance. For transmission security, CRC (Cyclic Redundancy Check) algorithm is for data transmission protection. Design of each module is platform-independent of macro cells, and keeps a better portability. Custom integrated instructions and interfaces may facilitate easily to use. Finally, the actual test went through multi-platform method, Xilinx and Altera FPGA developing platforms. The timing simulation and debugging of each module was covered. Finally, Test results show that the designed FPGA-based file system IP on SD card can support SD card, TF card and Micro SD with 2.0 protocols, and the successful implementation of systematic management for stored files, and supports SD bus mode. Data read and write rates in Kingston class10 card is approximately 24.27MB/s and 16.94MB/s.

We study competitive market outcomes in economies where agents have other-regarding preferences. We identify a separability condition on monotone preferences that is necessary and sufficient for one’s own demand to be independent of the allocations and characteristics of other agents in the economy. Given separability, it is impossible to identify other-regarding preferences from market behavior: agents be- have as if they had classical preferences that depend only on own consumption in competitive equilibrium. If preferences, in addition, depend only on the final allocation of consumption in society, the Sec- ond Welfare Theorem holds as long as an increase in resources can be distributed such that all agents are better off. Nevertheless, the First Welfare Theorem generally does not hold. Allowing agents to care about their own consumption and the distribution of consump- tion possibilities in the economy, we provide a condition under which agents have no incentive to make direct transfers, and show that this condition implies that competitive equilibria are efficient given prices.

The 42th meeting of the ICES Working Group on Introductions and Transfers of Marine Organisms (WGITMO) was held in Olbia, Italy, 16–18 March 2016, with Anna Occhipinti-Ambrogi as host and Henn Ojaveer as chairperson. Representatives from 19 countries participated in the meeting. Attendants were from Belgium, Canada, Dennark, Estonia, Finland, France, Germany, Ireland, Israel, Italy, Lithuania, Norway, Poland, Portugal, Russia, Spain, Sweden, United Kingdom and United States. Sweden contributed by cor-respondence. The objectives of the meeting were to update information and discuss several aspects related to the introductions and transfers of non-indigenous aquatic species. Data and information management were two of the discussion topics of the meeting, with special focus on the better exploitation of the ‘Information system on aquatic non-indigenous and cryptogenic species’ (AquaNIS). The WGITMO also dedicated time for addressing the MSFD D2 issues: indicator on new non-indigenous species introduced by human activities, and opportunities and problems related to cross-regional comparison of non-indigenous species indicators. Preparation of the manuscript of the alert report on sea squirt Didemnum vexillum, which is to be published in ICES CRR series, was discussed and the steps to be taken to finalise the report were agreed. As usual, adequate time was devoted to discuss national reports, to exchange of information on the management of NIS and to review ongoing and planned research activities. The approach taken during the meeting facilitated presentations and discussions on the issues of relevance related to the Terms of References as well as on a few generic and strategically-important issues of general relevance to bioinvasions. The meeting began with a full-day joint meeting with the Working Group on Ballast and Other Ship Vectors (WGBOSV), which provided an opportunity to discuss and address issues of common interest, such as shipping and biofouling as introduction vectors. The proposed ICES demonstration advice on ‘Risk management of non-indigenous species associated with shipping in the Arctic’ was discussed, and edits were suggested for both the orientation of the demonstration advice as well as for the exact questions to be asked. Both working groups agreed that the practice of conducting back-to-back meetings with one joint day is useful and will continue in 2017. All Terms of References to be addressed for 2016 were discussed. For some Terms of Ref-erence, more detailed presentations were given, and a short overview of the information and subsequent discussion is provided herein at the end of each section. This report is structured so that each Term of Reference is dealt with in sequential order. The main body of the report contains summaries of the presentations and discussions with the more detailed documents being contained in the Annexes. WGITMO progressed each of the Terms of Reference by either completing the task or clearly identifying and agreeing on the inter-sessional activities required to still finalise the work in 2016. From 2017, WGITMO will be shifted to multi-annual management.

Esta dissertação pretende contribuir para um melhor conhecimento da complexidade das redes de transferência de conhecimentos e técnicas, no domínio da engenharia civil e mais concretamente através dos caminhos-de-ferro, nos séculos XIX e XX. Em Portugal, os caminhos-de-ferro estiveram no cerne de um vasto debate, sobretudo político, concomitante com uma instabilidade crescente no cenário político e uma fase de fragilidade económica. É neste contexto que a Linha do Sul e Sueste vai ser construída (seguida pela sua extensão até Vila Real de Santo António e pela construção do ramal de Portimão, que chegará a Lagos). Este empreendimento é uma clara ilustração da realidade portuguesa de então, no que concerne ao desenvolvimento desta rede de transportes, que nos permite, igualmente, conhecer e compreender quem interveio no processo de construção da linha (os engenheiros, as empresas, entre outros aspectos) e assim determinar quais as influências e transferências técnicas que tiveram lugar; RESUMEE: Cette mémoire attire à la contribution pour une meilleure connaissance de la complexité des réseaux de transfert de techniques et connaissances qui ont eu lieu dans le domaine de l’ingénierie civile, surtout dans les chemins de fer, au XIXème et XXème siècles. Au Portugal, les chemins de fer sont été le cerne d’un très vaste débat, coïncidant avec une croissante instabilité dans le scenario politique et aussi une phase économique fragile. C’est dans ce contexte que la Ligne du Sud et Sud-est va être bâti (suivi par l’extension jusqu’à Vila Real de Santo António et la construction de l’embranchement ferroviaire Portimão). Cette entreprise c’est une illustration claire de la réalité portugaise, en concernant l’implémentation de cette réseau de transport, que nous permettre de comprendre et également bien connaitre qui a intervenu dans le processus de construction de la ligne (les ingénieurs, entreprises, etcetera), ainsi que déterminer les influences et les transferts techniques qui ont eu lieu; ABSTRACT: With this master’s thesis, the aim is to be able to contribute to a better understanding of the complex network of technique’s and knowledge transfers, that took place within the field of civil engineering, in the 19th and 20th centuries, namely on the railways. In Portugal, railways take-up was a wide and ample debate, coinciding with an uprising turmoil on the Portuguese political outskirt and a phase of economic frailty. It’s in this context that the construction of the South and Southeast Line took place (followed, later on, by its extension until Vila Real de Santo António and by the construction of the Portimão’s branch). This enterprise is, as we pretend to prove in this master’s thesis, a clear example of the Portuguese reality, enabling us to understand and to get to know those who intervened in the construction’s process (the engineers and the companies) as well as determining influences and technique transfers that have taken place.

Every Argo data file submitted by a DAC for distribution on the GDAC has its format and data consistency checked by the Argo FileChecker. Two types of checks are applied: 1. Format checks. Ensures the file formats match the Argo standards precisely. 2. Data consistency checks. Additional data consistency checks are performed on a file after it passes the format checks. These checks do not duplicate any of the quality control checks performed elsewhere. These checks can be thought of as “sanity checks” to ensure that the data are consistent with each other. The data consistency checks enforce data standards and ensure that certain data values are reasonable and/or consistent with other information in the files. Examples of the “data standard” checks are the “mandatory parameters” defined for meta-data files and the technical parameter names in technical data files. Files with format or consistency errors are rejected by the GDAC and are not distributed. Less serious problems will generate warnings and the file will still be distributed on the GDAC. Reference Tables and Data Standards: Many of the consistency checks involve comparing the data to the published reference tables and data standards. These tables are documented in the User’s Manual. (The FileChecker implements “text versions” of these tables.)

There is an increasing concern to reduce the cost and overheads during the development of reliable systems. Selective protection of most critical parts of the systems represents a viable solution to obtain a high level of reliability at a fraction of the cost. In particular to design a selective fault mitigation strategy for processor-based systems, it is mandatory to identify and prioritize the most vulnerable registers in the register file as best candidates to be protected (hardened). This paper presents an application-based metric to estimate the criticality of each register from the microprocessor register file in microprocessor-based systems. The proposed metric relies on the combination of three different criteria based on common features of executed applications. The applicability and accuracy of our proposal have been evaluated in a set of applications running in different microprocessors. Results show a significant improvement in accuracy compared to previous approaches and regardless of the underlying architecture.

On the 15th of April, 1897, a 19 year-old European resident of Baghdad, named Alexander Richard Svoboda, set out on a long journey to Europe by caravan, boat and train. From a large and influential family of merchants, artists, and explorers settled in Ottoman Iraq since the end of the 18th century, Alexander traveled in the company of his parents and a departing British diplomat accompanied by his retinue. They followed a circuitous route through the Middle East to Cairo and thence to Europe on a three and a half month journey which Alexander described day-by-day in a journal written in the Iraqi Arabic of his time.
