The 5th generation mobile telecommunication system (5G) is currently being specified and developed, with large expectations on throughput and efficiency. While 4G and more specifically LTE might constitute a basis of the design of the network, there are some parts that should be improved. One thing to improve is the static signalling that occurs very frequently in a 4G network, of which system information such as synchronization signals, detection of network frequencies, operators, configurations etc. is a part. It has been shown that the static signalling requires both much energy and time-frequency resources. Since the system information is not intended for a single user it is always broadcast so that any user, and any amount of users can read it when needed. 5G will use a technique called massive MIMO, where the base station is equipped with a large number of antennas which can be used to direct signals in space, called beamforming. This thesis presents a new method for distribution of system information that can utilize the beamforming capabilities of massive MIMO. A simple model together with simulated user channel statistics from urban 4G scenarios are used to show that the new method outperforms the classical method of only broadcasting the information, with respect to time-frequency resources. Especially if there are high requirements on the latency of the system information, the new method results in a large gain.

E-learning systems provide a promising solution as an information exchanging channel. Improved technology could mean faster and easier access to information but does not necessarily ensure the quality of this information. Therefore it is essential to develop valid and reliable methods of quality measurement and carry out careful information quality evaluations. Information quality frameworks are developed to measure the quality of information systems, generally from the designers' viewpoint. The recent proliferation of e-services, and e-learning particularly, raises the need for a new quality framework in the context of e-learning systems. The main contribution of this thesis is to propose a new information quality framework, with 14 information quality attributes grouped in three quality dimensions: intrinsic, contextual representation and accessibility. We report results based on original questionnaire data and factor analysis. Moreover, we validate the proposed framework using an empirical approach. We report our validation results on the basis of data collected from an original questionnaire and structural equation modeling (SEM) analysis, confirmatory factor analysis (CFA) in particular. However, it is difficult to measure information quality in an e-learning context because the concept of information quality is complex and it is expected that the measurements will be multidimensional in nature. Reliable measures need to be obtained in a systematic way, whilst considering the purpose of the measurement. Therefore, we start by adopting a Goal Question Metrics (GQM) approach to develop a set of quality metrics for the identified quality attributes within the proposed framework. We then define an assessment model and measurement scheme, based on a multi element analysis technique. The obtained results can be considered to be promising and positive, and revealed that the framework and assessment scheme could give good predictions for information quality within e-learning context. This research generates novel contributions as it proposes a solution to the problems raised from the absence of consensus regarding evaluation standards and methods for measuring information quality within an e-learning context. Also, it anticipates the feasibility of taking advantage of web mining techniques to automate the retrieval process of the information required for quality measurement. This assessment model is useful to e-learning systems designers, providers and users as it gives a comprehensive indication of the quality of information in such systems, and also facilitates the evaluation, allows comparisons and analysis of information quality.

This study focuses on the financial management of movable property in the Center of Biological and Health Sciences (CCBS) of the Federal University of Maranhão (UFMA), according to Torres Junior (2003) the wealth management is to plan, organize, control, ensure, conserve and promote the best use of permanent materials available in the organization. This research aims to examine the criteria adopted in the processes of acquisition and disposal of permanent materials. Therefore, we discussed knowledge of the asset management regulations applied to heritage resources, information technology in public administration and sustainable logistics plan. This knowledge is grounded in the views of authors such as Davemport (1994), Moresi (2000), Francischini and Gurgel (2002), Cross (2003), Coutinho (2004), Silva, Ribeiro and Rodrigues (2004), Martins et AL (2007 ), Oliveira (2007), Pozo (2007), Bobsin and Lobler (2008), Carvalho Filho (2008), Gomes and Tortato (2010), Santos (2012), Meirelles (2012), Vinhais, Manso and Silva (2012) , Meza and Fijor (2013), among others. This case study is descriptive, exploratory and qualitative. Two questionnaires were applied to servers with the academic departments of the CCBS and Registration Division Asset respectively, and proceeded the analysis of existing documentation in the archives of the institution on the financial management which enabled the collection of data that were subsequently analyzed. The results show that the studied unit has been unable to efficiently manage its property, not given the precepts both the current legislation, as the organs of internal and external control. In one of the goals are some proposals for improvements, such as preparation of a manual of procedures based on current legislation, promote seminars on asset management. / O presente estudo trata sobre a gestão patrimonial de bens móveis no Centro de Ciências Biológicas e da Saúde (CCBS) da Universidade Federal do Maranhão (UFMA), segundo Torres Junior (2003) a administração patrimonial consiste em planejar, organizar, controlar, zelar, conservar e promover a melhor utilização dos materiais permanentes disponíveis na organização. A presente pesquisa tem como objetivo principal analisar os critérios adotados nos processos de aquisição e de descarte de materiais permanentes. Para tanto foram discutidos conhecimentos sobre a gestão patrimonial, legislação aplicada aos recursos patrimoniais, a tecnologia de informação na administração pública e o plano de logística sustentável. Esses conhecimentos estão alicerçados nas visões de autores como Davemport (1994), Moresi (2000), Francischini e Gurgel (2002), Cruz (2003), Coutinho (2004), Silva, Ribeiro e Rodrigues (2004), Martins et AL (2007), Oliveira (2007), Pozo (2007), Bobsin e Lobler (2008), Carvalho Filho (2008), Gomes e Tortato (2010), Santos (2012), Meirelles (2012), Vinhais, Manso e Silva (2012), Meza e Fijor (2013), dentre outros. Este estudo de caso é descritivo, exploratório e de natureza qualitativa. Foram aplicados dois questionários junto aos servidores dos departamentos acadêmicos do CCBS e da Divisão de Registro Patrimonial, respectivamente, e procedida a análise da documentação existente nos arquivos da instituição sobre a gestão patrimonial, que possibilitou a coleta de dados que posteriormente foram analisados. Os resultados revelam que a unidade pesquisada não vem conseguindo gerenciar de forma eficiente seus bens móveis, não atendendo ao que preceitua tanto a legislação vigente, quanto os órgãos de controle interno e externo. Em um dos objetivos são apresentadas algumas propostas de melhorias, tais como, elaboração de um manual de procedimentos baseado na legislação vigente, promover seminários sobre a gestão patrimonial.
