FPGA Design Tools - : the Challenges of Reporting Performance DataPersson, Stefan January 2016 (has links)
Since its introduction in the 1980s, field-programmable gate arrays have seen a growing use over the years. Nowadays FPGAs are found in everything from planetary rovers and base transceiver stations to bitcoin miners. With the technological advancements and the growth of the market, there has been a steady flow of new models with increasing capacity. To make it possible to use this capacity in an efficient way, also the software tools have been improved. The applications in research have grown and so has the will to compare both the speed and size between different implementations that try to solve the same or similar problem. However, how to make a good comparison is not well defined. Since few research papers have source code available, such comparisons are hard to make and there is a high risk of comparing apples to pears. In this thesis, we will study the impact of different software settings and design constraints on the FPGA design flows to better understand how to report research results. This will be done by running selected designs through different EDA tools, using various settings and finally analyse the data the tools provide. At the end we will begin to define guidelines for how to report and compare implementation data, to give a good account of their performance compared to other designs.

Much Ado About Immersion: Power, Reported Results, and the Validity of Research on the Psychology of Virtual Reality and Immersive SimulationsLanier, Madison Kathryn 26 June 2018 (has links)
Virtual reality (VR) technology has permeated consumer culture in recent years, consequentially inspiring a hotbed of interdisciplinary academic VR research to better understand its effects as a medium. It has become a popular subject of study in fields as varied as engineering, computer science, communication, and psychology. The present study evaluates methodological trends in behavioral research on VR in terms of best practices regarding data collection, reporting, and availability. A meta-scientific content analysis of 61 articles focused on power, p-values, reporting errors, and transparency of data, all of which respectively represent four stages of research: data collection, analysis, reporting, and sharing. The findings from 1,122 statistical tests show that there is room for improvement in much behavioral research on VR in terms of methodological trends regarding number of participants, reporting of results, and data availability. Although no firm conclusions can be drawn about the presence of p-hacking or other questionable research practices (QRPs), the present study demonstrates that chronically small sample sizes, instances of errors in reporting, and a lack of transparent supplemental data are evident. The trends observed are broad, yet informative, and further research in this area is crucial. Methodological recommendations are made for future research dealing with VR applications, particularly given the potential social and cultural impact of the technology. / Master of Arts

Previous issue date: 2005-02-11 / Universidade Estadual Paulista J?lio de Mesquita Filho / Assessing scientific production on brief psychodynamic psychotherapies becomes a necessary activity for designing the profile of trends and perspectives in the area. The paper analyzes, describes and compares studies published in two national journals (Estudos de Psicologia/EP and Jornal Brasileiro de Psiquiatria/JBP; 35,8% of the production) and in two foreign ones (Journal of Consulting and Clinical Psychology/JCCP and Psychotherapy and Psychosomatis/PP; 64,2% of the production) (N=81) . The distribution of the production concentrates in the 1990 s; on the whole, the national one rises in institutions of the Southeastern region and the foreign one in North American institutions. The male sex is the significant gender among authors, and the multiple authorship is the one appearing most frequently. The most frequent text support among the Brazilian ones is the book, and among the foreign ones are the articles. The most frequently journals in the articles are, in general, the ones analyzed: JBP, JCCP and mainly PP. National authors make significant use of foreign production for technical-theoretical foundation of their papers; among foreigners, the use of journals produced in their own countries. English is significantly the language of the references. The use of current references, between 0 and 5 years, is significant. In the Brazilian production the authors are quoted in a width ranging from 1 to 16 times and in the foreign one, from 1 to 66 times. In the national production David Malan, Sigmund Freud, Mauricio Knobel and Hector Fiorini are the most quoted; in the fore ign one, David Malan, Hans Strupp, David Shapiro, Lester Luborsky, Peter Sifneos and Ragnhild Husby. In general, empirical studies predominate. Adults of both sexes, seen individually, design the profile of the target population. Several pathologies/complaints are investigated; th ere are signs of some highlight to depression. Clinical scales are the most used tools for psychological assessment. The correlational design predominates in the empirical researches. The integrative theoretical model is the most frequent among Brazilian authors; among foreigners, the drive/structural is significantly the most used one. Altogether, qualitative differences do not appear in relation to the studied variables, although the foreign production is numerically greater. / Avaliar produ??o cient?fica sobre psicoterapias breves psicodin?micas trata-se de atividade necess?ria para o tra?ado do perfil de tend?ncias e perspectivas na ?rea. O trabalho analisa, descreve e compara estudos publicados em dois peri?dicos nacionais (Estudos de Psicologia/EP e Jornal Brasileiro de Psiquiatria/JBP; 36% da produ??o) e em dois estrangeiros (Journal of Consulting and Clinical Psychology/JCCP e Psychotherapy and Psychosomatics/PP; 64% da produ??o) (N=81). A distribui??o da produ??o concentra-se na d?cada de 1990; de forma geral, a nacional origina-se em institui??es da regi?o Sudeste e a estrangeira em institui??es norte-americanas. O sexo masculino ? o g?nero significante entre os autores, e a autoria m?ltipla a mais freq?ente. O suporte de texto significantemente mais citado entre os brasileiros ? o livro, e entre os estrangeiros os artigos. Peri?dicos mais citados nos artigos analisados s?o, no geral, os pr?prios analisados: JBP, JCCP e principalmente o PP. Autores nacionais utilizam-se para fundamenta??o te?rico-t?cnica de seus trabalhos de produ??es estrangeiras de modo significante; entre estrangeiros, o uso de peri?dicos produzidos em seus pr?prios pa?ses. O idioma das refer?ncias citadas ? significantemente o ingl?s. O uso de refer?ncias recentes, entre 0 e 5 anos, ? significante. Na produ??o nacional os autores s?o citados numa amplitude que varia de 1 a 16 vezes e na estrangeira, de 1 a 66 vezes. Na produ??o nacional David Malan, Sigmund Freud, Mauricio Knobel e Hector Fiorini s?o os mais citados; na estrangeira, David Malan, Hans Strupp, David Shapiro, Lester Luborsky, Peter Sifneos e Ragnhild Husby. Em geral, estudos emp?ricos predominam. Adultos de ambos os sexos, atendidos na modalidade individual, desenham o perfil da popula??o alvo. V?rias as patologias/queixas s?o investigadas; h? ind?cios de certo destaque para depress?o. Escalas cl?nicas s?o os instrumentos de avalia??o psicol?gica mais utilizados. O delineamento correlacional predomina nas pesquisas emp?ricas. O modelo te?rico integrativo ? o mais freq?ente na orienta??o dos trabalhos escritos por brasileiros; entre estrangeiros, o impulsivo-estrutural ? significantemente mais utilizado. De modo geral, n?o se verifica diferen?as qualitativas em rela??o ?s vari?veis estudadas, embora a produ??o estrangeira seja numericamente superior.
