Color management has become more common now than ever in the graphic trade. Calibration andcharcterization are words that are mentioned very often when it comes to controlling colors andwhen you want a printed picture to look the same as an original photograph. The problem is thatthere are not so many people that has the knowlegde about this subject. Even if a printer supportscolor management it is not sure that the result is going to be satisfied and that a printed picture isgoing to look the same as the original.The printers which were used were Hp DeskJet 970 Cxi, Xerox Docu Color 12 and AgfaChromapress 50i. The theory of color, colour management and the equipment which were usedare described in the first stage. The second stage describes calibration and characterization ofmonitors, scanners and printers. Finally the result of created ICC-profiles is set by visual comparisionof a photographs original colours and a scanned and printed photograph.The results of calibration and characterization were varying a lot. Agfa Chromapress 50i was theonly printer which could produce a succesful calibration. Agfa Chromapress 50i and XeroxDocuColor 12 gave the best results when comparing original photographs with printed pictures ifthey were separated with ICC-profiles. ICC-profiles created for Hp DeskJet 970 Cxi achievedundesirable effects. This was the only printer that gave a bad result both with and without ICCprofiles.The reason for this miserable result can depend on the printers unability to fully supportcolor management.

I detta examensarbete har gråbalansstyrning och ICC-profilers duglighet undersökts. ICC-profilernahar utvärderats utifrån den tryckkvalitet de genererat tillsammans med olika papper.Gråbalansstyrning har använts som gemensamma likare för samtliga testtryckningar. Detta tillfördeen variabel som var lika för samtliga papper i utredningen. Här med ökade sannolikheten att ICCprofilerskapade från olika papper, skulle ge en likvärdig kvalitet.I arbetet har många mätningar och beräkningar genomförts. De två främsta anledningarna till dettavar dels att utreda i vilken mån det gick att gråbalansjustera trycket och dels att inhämta jämförbaravärden på likheter och divergenser mellan olika kombinationer av ICC-profiler och papper. Mätdatahjälpte även till att ta hänsyn till de felkällor som fanns.Det var möjligt att gråbalansjustera trycket och det fanns likheter mellan en ICC-profil på olika papperoch även mellan fler ICC-profiler på samma papper. Samtliga resultat och slutsatser var beroendeav att neutral gråbalans upprätthölls under tryckningarna. Subjektiva och objektiva jämförelser visadebåda på att en ICC-profil inte kommer att påverkas av variationer mellan olika pappersleveranser,såvida dessa inte är större än skillnaden mellan de olika papperna.Med säkerhet kunde inte förutsägas från vilket papper en ICC-profil skulle skapas för att ge en högkvalitet på flera papper. Mest troligt var att likvärdigt resultat skulle kunna uppnås på G-Print, MultiArt Matt och Multi Art Silk.

Adjustment to a neutral colour balance when printing was the starting point in this degree project. Onthis base ICC-profiles were evaluated and assessed. The survey was concentrated on the similarity betweenreproductions on different papers with various ICC-profiles. The colour balancing introduced aconsistent variable between four graphic papers. With raised uniformity the probability increased toreceive similarities between the various combinations of ICC-profiles and papers.Numerous of measurements and calculations have been carried out, mainly to confirm whether or notadjustment to a neutral colour balance is possible and repeatable. Further more this gained in comparablevalues corresponding to similarities and divergences between combinations of ICC-profiles andpaper.The research concluded in the fact that it was possible to reach a neutral colour balance. One ICCprofileused together with various papers and also one paper with several ICC-profiles resulted in similaritiesand formed groups of samples. Since equivalent results could be reached on different samples,it implicated that variations within one paper shouldn’t affect the ICC-profiles. This was valid when thevariations were less than the divergence between the papers.Certain predictions on the question of from which paper the ICC-profiles should be generated to createhighest quality in print hasn’t been able to assemble. It’s likely that equivalent results could begenerated on G-Print, Multi Art Matt and Multi Art Silk.

The connection between fluorescence and color management still is a relatively unexplored area. Thefollowing composition analyses the theory that when printing on fluorescent ink jet paper using ICCprofilesa more yellow print will appear. In theory the ICC-profile compensate for blue light that fluorescefrom the paper with the complementary color, yellow. The human eye apprehands this fluorescentlight as white.When categorizing a number of ink jet qualities some tests to indicate change of color in the final printwere made. Five qualities were chosen for further analyses, each with different white point. TheTC3.5CMYK target was prined on an ink jet printer and measured with different filters for the measurementequipment, GretagMacbeth Spectrolino. U- and UV-filters were used during the testings.From the measurement data ICC-profiles were made to make it possible to watch how the profiles compensatefor the blue change of color that appeared in the data. Although a distinct change of color intoblue were discernible in the measured data there is no evident proof that this cause a final print thatis more yellow. Other conclusions and results are to be read at the end of this composition.

This study explores the relationships that emerge between socioeconomic status (SES) and the prevalence of several health outcomes in children of different ages utilizing administrative data housed at The Manitoba Centre for Health Policy (MCHP). This research also determines the effect that family has on a child developing (or not developing) a specific health outcome. Finally, the relationship between prevalence and familial aggregation are examined. The Johns Hopkins ACG(r) Case-Mix System grouped various physician and hospital diagnosis codes into 32 Aggregated Diagnostic Groups (ADGs). Eight of these ADGs were assessed at four age groups (0-3, 4-8, 9-13 & 14-18) for each member of the final study population. Each member was assigned to one of six SES groups, five income quintile groups and one social assistance group. Familial aggregation was determined for eight selected ADGs using an intraclass correlation coefficient (ICC). Statistical contrasts were made for SA vs. Q1-Q5 and an overall linear trend (SA – lowest; Q5 – highest) to establish the SES differences for the prevalence and familial aggregation of a particular condition. Many of the conditions across SES had statistically significant (p<0.05) linear and SA vs. Q1-Q5 contrasts for 3 both ICCs and prevalence at all age groups. Of the eight ADGs that familial aggregation was calculated, chronic conditions related to the eye had the highest ICCs at all age groups. Injury ADGs had consistently lower ICCs for all age groups. Factors that affected the results of ICC estimation for binary outcomes include the number of bootstrap selections, the width of the age group and the event rate for the outcome of interest. Suggested future research includes a validity review of ICC estimates for binary outcomes, exploring the variables that may reduce or eliminate the SES gradient for ICCs and exploring the aggregation for different study samples within Manitoba.

Novas tecnologias têm surgido para prover a essas pessoas um canal de comunicação alternativo através de sinais cerebrais. Esses sistemas são conhecidos como Interfaces Cérebro-Computador (ICCs). Este trabalho descreve o desenvolvimento de uma ICC baseada no paradigma de Potenciais Evocados Visuais de Regime Permanente (Steady State Visual Evoked Potential - SSVEP) aplicada à Comunicação Alternativa e Robô de Telepresença. A interface foi construída para quatro comandos de seleção atráves de estímulos visuais desenvolvidos em um software utilizando a biblioteca grá&#64257;ca OpenGL e executados em frequências distintas (5,6Hz, 6,4Hz, 6,9Hz e 8,0Hz). Todos os voluntários avaliados nos testes utilizando o sistema online conseguiram completar as tarefas propostas com uma taxa de acerto média de 88,3% ± 5,4%, tempo de classi&#64257;cação de 5,6s ± 0,5s e ITR média de 14,2 bits/min ± 3,5 bits/min, não necessitando de treinamento e utilizando apenas um canal para aquisição do sinal eletroencefalográ&#64257;co. Os resultados demonstraram a possibilidade da construção de uma ICC que poderá ser utilizada nos futuros projetos de tecnologias assistivas desenvolvidos no Laboratório de Automação Inteligente da Universidade Federal do Espírito Santo (LAI-UFES).

Este tipo de ICC permite que pessoas com dificuldades motoras severas possam se comunicar com o mundo exterior através da modulação da atenção visual a luzes piscantes com frequência determinada. Esta Tese de Doutorado tem o intuito de desenvolver um novo enfoque dentro das chamadas ICC Independentes, nas quais os usuários não necessitam executar tarefas neuromusculares para seleção visual de objetivos específicos, característica que a distingue das tradicionais ICCs-SSVEP. Assim, pessoas com difculdades motoras severas, como pessoas com Esclerose Lateral Amiotrófca (ELA), contam com uma nova alternativa de se comunicar através de sinais cerebrais. Diversas contribuições foram realizadas neste trabalho, como, por exemplo, melhoria do algoritmo extrator de características, denominado Índice de Sincronização Multivariável (ou MSI, do Inglês), para a detecção de potenciais evocados; desenvolvimento de um novo método de detecção de potenciais evocados através da correlação entre modelos multidimensionais (tensores); o desenvolvimento do primeiro estudo sobre a in&#64258;uência de estímulos coloridos na detecção de SSVEPs usando LEDs; a aplicação do conceito de Compressão na detecção de SSVEPs; e, fnalmente, o desenvolvimento de uma nova ICC independente que utiliza o enfoque de Percepção Fundo-Figura (ou FGP, do Inglês).
