Abstract:
Control charts have played an important role in monitoring the performance of operation processes, ever since their invention. Traditionally, according to Juran's idea and others, x‐bar charts are more sensitive than individual x‐charts. However, such a conclusion is valid only under certain conditions. Individual x‐charts can outperform x‐bar charts in some situations, especially in cases of minor and extreme changes of the center value. Since each chart has its own advantages and disadvantages, the idea of combining the results of these two charts is studied. The finding seems to be useful for practitioners in quality control.

Abstract:
The existing Shewhart X-bar control charts using the exponentially weighted moving average statistic are designed under the assumption that all observations are precise, determined, and known. In practice, it may be possible that the sample or the population observations are imprecise or fuzzy. In this paper, we present the designing of the X-bar control chart under the symmetry property of normal distribution using the neutrosophic exponentially weighted moving average statistics. We will first introduce the neutrosophic exponentially weighted moving average statistic, and then use it to design the X-bar control chart for monitoring the data under an uncertainty environment. We will determine the neutrosophic average run length using the neutrosophic Monte Carlo simulation. The efficiency of the proposed plan will be compared with existing control charts.

Abstract:
This study compares participants’ performance in extracting information from three-dimensional pie charts with individually extruded sectors in a single map frame against two-dimensional pie and bar charts in adjacent map frames. Specifically, we examine the response accuracy and response times of 181 adults who were asked to (1) identify the highest magnitude, (2) estimate a proportion, (3) perform both at the same time, and (4) solve a map-related task using the two chart setups. For each task, charts were shown on backgrounds with increasing visual complexity: a blank, a borders-only, and a choropleth map. Furthermore, we tested whether participants’ performance improved through additional practice with the two chart types. We did not observe any differences in participants’ aggregated response accuracy or response times between the tested three-dimensional and two-dimensional chart types for the (1) highest magnitude task and (2) proportion task. However, participants solved the (3) combination task with two-dimensional pie and bar charts on a blank background more accurately and were faster in fulfilling the (4) spatial task with three-dimensional pie charts. The first difference, however, leveled for participants who gained more practice and who accomplished the combination task on maps with higher visual complexity, whereas the second difference persisted even for more trained subjects.

Abstract:
Graphs are useful to communicate concisely about complex issues. Although they facilitate intuitive reading of data, trends, and predictions, hasty readers may still come to the wrong conclusions, especially if graphs are misleading due to violated design conventions. To provide evidence about how to prevent misinformation from spreading by misleading graphs, this two-survey experimental study investigates the effectiveness of four correction methods as debunking strategies to correct bar charts with manipulated vertical axes. All four methods showed positive effects. The most effective one is aimed at correcting the initial image by presenting an accurate alternative graph. A reduced effect remained visible after one week.

Abstract:
Abstract Some researchers, in their published articles in authentic scientific journals, plot calibration curves using bar charts instead of scatter plots using common software such as Excel. Bar charts can significantly affect the apparent linear range and sensitivity of the developed method, and using bar charts as calibration curves gives the wrong results. Therefore, this issue should be considered by researchers in developing analytical methods.

Abstract:
Subjects judged change and proportion when viewing graphs in two experiments. Change was judged more quickly and accurately with line and bar graphs than with pie charts or tiered bar graphs, and this difference was larger when the rate of change was smaller. Without a graduated scale, proportion was judged more quickly and accurately with pie charts and divided bar graphs than with line or bar graphs. Perception is direct when it requires simpler or fewer mental operations; we propose that perception of change is direct with line and bar graphs, whereas perception of proportion is direct with pie charts and divided bar graphs. The results are also consistent with the proximity compatibility principle. Suggestions for improving the design of graphical displays are given.

Abstract:
Rapporten täcker vidareutvecklingen av en grafkomponent som från början kunde visa linjediagram med datapunkter bestående av reella tal. Grafkomponenten var en del av programvaran Tunnel Manager som är utvecklad av Sogeti till Atlas Copco. Tunnel Manager används i kombination med Atlas Copcos borrigg Boomer. Grafkomponenten utvidgades med stapeldiagram med flera serier, stapeldiagram med adderade serier och med cirkeldiagram. Den utvidgades även med nya datapunktstyper i form av datum och tid. Även gruppering av data för stapeldiagram lades till. Utökad information visades också när muspekaren hölls över ett diagram, ett så kallat tooltip. Zoom och panorering i diagrammen implementerades så användaren kunde granska vissa områden i detalj.  Rapporten omfattar även en utredning där det undersöktes vilken information och vilka diagram Atlas Copco hade behov av i framtiden i Tunnel Manager. Det visades sig att det fanns stort behov av att visa diverse information i diagram för att få ett bra underlag till beslutsfattning. Dels för planering av användandet av borriggen. Dels för underhåll av borriggen.  När stora mängder information samlas in behövs bra sätt att sammanfatta den på. Diagram är ett mycket bra sätt för detta ändamål. Diagrammen behöver dock följa vissa grundläggande regler för att de ska vara tillförlitliga. Bland annat att diagram som jämförs ska ha samma skala för att underlätta jämförelsen. Vidareutvecklingen av grafkomponenten tog hänsyn till dessa regler, det bidrog till att den lämpar sig att använda i produktion.<br>This report covers the further development of a chart component. The component could display a linechart with real number datapoints at the beginning. The chart component was part of as software called Tunnel Manager, developed by Sogeti for Atlas Copco. Tunnel Manager is used in combination with Atlas Copcos drilling rig Boomer. The charts added were barchart with support for several dataseries, stacked barchart with support for stacked dataseries and piechart. A new datapoint type for date and time was added. Grouping of data for the barcharts was also added.  Extended information was shown when the mouse pointer was held over a diagram, a tooltip. Zoom and panning in the charts was implemented, allowing the user to view some parts in detail.  The report also covers an investigation. The investigation finds out what kind of information, and what kinds of charts Atlas Copco had need of in the future in Tunnel Manager. There was a great need for displaying information in charts to get a good base for decision making. The information was needed for planning and maintenance of the drilling rigs.  When a lot of information is gathered from different sources a good way is needed for compilation and displaying of the information. Charts are a very good way of doing this. The carts need to follow a set of basic rules to be trustworthy. For example if several charts is to be compared, they need to have the same scale, to make it easier to compare. The further development of the chart component took these rules into account and it made it suitable for usage in production.

Full text
Abstract:
This study uses simulation to examine differences between fixed sampling interval (FSI) and variable sampling interval (VSI) Shewhart X-bar control charts for processes that produce positively autocorrelated data. The influence of sample size (1 and 5), autocorrelation parameter, shift in process mean, and length of time between samples is investigated by comparing average time (ATS) and average number of samples (ANSS) to produce an out of control signal for FSI and VSI Shewhart X-bar charts. These comparisons are conducted in two ways: control chart limits pre-set at ±3σ_x / √n and limits computed from the sampling process. Proper interpretation of the Shewhart X-bar chart requires the assumption that observations are statistically independent; however, process data are often autocorrelated over time. Results of this study indicate that increasing the time between samples decreases the effect of positive autocorrelation between samples. Thus, with sufficient time between samples the assumption of independence is essentially not violated. Samples of size 5 produce a faster signal than samples of size 1 with both the FSI and VSI Shewhart X-bar chart when positive autocorrelation is present. However, samples of size 5 require the same time when the data are independent, indicating that this effect is a result of autocorrelation. This research determined that the VSI Shewhart X-bar chart signals increasingly faster than the corresponding FSI chart as the shift in the process mean increases. If the process is likely to exhibit a large shift in the mean, then the VSI technique is recommended. But the faster signaling time of the VSI chart is undesirable when the process is operating on target. However, if the control limits are estimated from process samples, results show that when the process is in control the ARL for the FSI and the ANSS for the VSI are approximately the same, and exceed the expected value when the limits are fixed.

Full text
Abstract:
The appropriate selection of failure criterion for solder joint studies is necessary to correctly estimate reliability life. The objective of this study is to compare the effect of different failure criteria on the reliability life estimation. The four failure criteria in this study are a 20% resistance increase defined in the IPC-9701A standard, a resistance beyond 500 Ω, an infinite resistance (hard open), and a failure criterion based on X-bar and R control charts. Accelerated thermal cycling conditions of a low-silver BGA study included 0°C to 100 °C with ten minute dwell times and -40°C to 125°C with ten minute dwell times. The results show that the life estimation based on X-bar and R failure criterion is very similar to the life estimation when a 20% resistance increase defined in the IPC-9701A failure criterion is used. The results also show that the reliability life would be overestimated if the failure criterion of a resistance threshold of 500 Ω or an infinite resistance (hard open) is used.

CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior<br>O tratamento da informaÃÃo à importante para a formaÃÃo do cidadÃo, pois estamos cercados de dados e fatos que precisam ser compreendidos. Contudo, avaliaÃÃes recentes do Sistema de AvaliaÃÃo da EducaÃÃo BÃsica (SAEB) e do Instituto Nacional de Alfabetismo Funcional (INAF) indicam as dificuldades de estudantes e atà de adultos das diversas regiÃes do paÃs, apresentam no entendimento da representaÃÃo de dados em grÃficos e em tabelas e em compreender os conceitos matemÃticos envolvidos. Pesquisas revelam que o estudo de grÃficos atravÃs de recursos tecnolÃgicos como computador e tecnologias digitais, favorece o desenvolvimento da aprendizagem de conceitos estatÃsticos, pois, na maioria das vezes, auxiliam a visualizaÃÃo e a exploraÃÃo de um conjunto de atividades, propiciando novas formas de pensar e agir. Dessa forma, realizou-se uma intervenÃÃo com um conjunto de atividades baseada no uso de objetos de aprendizagem (OA), a fim de verificar como o uso de tecnologias digitais contribui na aprendizagem de conceitos envolvidos no tratamento da informaÃÃo como construÃÃo e interpretaÃÃo de grÃficos de barras e de setores. A pesquisa foi realizada em uma escola pÃblica municipal de Fortaleza participante do Projeto Um Computador por Aluno - UCA, com duas turmas do 5 ano do Ensino Fundamental, com 26 alunos em cada uma. As turmas foram divididas em: Grupo Controle (GC) e Grupo Experimental (GE). A investigaÃÃo foi dividida em trÃs etapas: prÃ-teste, intervenÃÃo e pÃs-teste. Todos os alunos participaram do prÃ-teste e do pÃs-teste, aplicados individualmente e sem uso do computador. Todavia, ao GC nÃo foi ministrado nenhuma instruÃÃo formal alÃm da recebida em sala de aula. O GE foi submetido à intervenÃÃo que contemplou: aspectos matemÃticos de grÃficos e tabela, situaÃÃes-problema com classificaÃÃo e proporcionalidade e atividades de investigaÃÃo. Os dados foram analisados de modo a conhecer e compreender o desempenho dos alunos antes e apÃs as atividades, a evoluÃÃo de estratÃgias e o tratamento da informaÃÃo. Os estudantes que foram submetidos à intervenÃÃo apresentaram, estatisticamente, um desempenho superior quando comparado aos estudantes do GC. Constatou-se a evoluÃÃo das estratÃgias das crianÃas do GE, a partir de atividades desenvolvidas durante pesquisa. Essas atividades proporcionaram a integraÃÃo das diferentes tecnologias existentes na escola ao currÃculo escolar (laptop, tecnologias digitais e analÃgicas). Assim, o uso de tecnologias digitais permitiu a vivÃncia de experiÃncias didÃticas de tratamento da informaÃÃo das quais possibilitou: visualizar e simular diferentes situaÃÃes (representaÃÃo de grÃficos diferentes, de coleta e anÃlise de dados); tratar a informaÃÃo; trabalhar com situaÃÃes reais e com contextos investigativos e explorar os dados produzidos. Logo, os resultados deste estudo contribuem para melhor compreender a aprendizagem de grÃficos, assim como para o desenvolvimento de novos recursos e atividades.<br>The information processing is important for the citizen formation, since we are surrounded by data and facts that need to be understood. However, recent evaluations such as SAEB and INAF indicated the difficulties that children and adults from several Brazilian regions have been in the understanding of the processes related to data representation in graphs and tables, as well as understand involved mathematical concepts. Research have showed that the study of graphs by using of technological devices such as computer and another digital technologies, favoring the development of statistical concepts learning since these strategies help the visualization and exploration of many activities, providing new ways of thinking and act. Thus, the current study investigated as a didactic sequence, using learning objects (LO), could help in the understanding of concepts related to information processing as the construction and interpretation of bar and sectors graphs. The work was conducted in a Brazilian public school located in Fortaleza city using two classes of 5th grade of elementary school, with 26 students each ones. The school classes were divided in control group (CG) and experimental group (EG) and all students were previously evaluated through a pre-test. Posteriorly an intervention using a didactic sequence including mathematical aspects of graphs and tables, problem situations with classification and proportionality and research activities was performed only with EG. The GC was not exposed to any formal education beyond the classroom received. Thereafter a post test was applied to both groups (CG and EG). The data were analyzed by student performance before and after the performed activities taking into account the evolution of strategies and information processing. Was observed a improviment in the strategies used by children for GE group after intervention. These activities give the integration of different technologies employed in school curriculum (laptop and digital and analogic technologies). Thus, the use of digital technologies provided didatic experiences in processing information by students as a to visualize and simulate different situations; process information; work with real situations, with investigative contexts and explore the produced data. Therefore, the results of current study contribute to better understand the graphs learning as well as for further development of new resources and activities.

Abstract:
Studien görs i samarbete med ett företag som jobbar med bl a. barnoveraller. Företaget gör ingen egen mönsterkonstruktion, utan köper denna tjänst av leverantören. Materialet leverantören får av företaget är en måttlista, men när olika leverantörer sytt upp prover åt dem har de fått varierande passform, trots att overallerna hållit samma mått. Författarna har därför jobbat på ett sätt att systematisera måttlistan för att kunna reproducera den aktuella passformen. Detta har gjorts genom att försöka återskapa företagets overall med hjälp av måttlistan och därefter utvärderat vad som skulle göra måttlistan mer tydlig och praktisk för leverantörerna. Utvecklingen av måttlistan har innefattat namn på mått, måttordning, samt skiss och placering av mått. Avgörande faktorer för passformen på barnoverallen har visat sig vara luvan, måttet axel till gren, midjeresår, knävidd och stussens position. En slutlig måttlista har tagits fram som ett förslag på ett sätt för företag utan egen mönsterkonstruktion att systematisera passformen.<br>The study is being conducted in collaboration with a company that works with, among other things, children's overalls. The company does not make its own pattern design, but buys this service from the supplier. The material the supplier receives from the company is a measurement chart. However when different suppliers have sewn samples for them, they have been of varying fit, despite the fact that the overalls have kept the same dimensions. The authors have therefore worked to systematize the measurement chart in order to be able to reproduce the current fit. This has been done by trying to recreate the company's overalls using the measurement chart and then evaluating what would make the measurement chart clearer and more practical for the suppliers. The development of the measurement chart has included names of measurements, measurement order, and sketch and placement of measurements. Key factors for the fit of the children's overalls have proven to be the hood, shoulder to crotch, waist elastic, knee width and the placement of the seat. A final measurement chart has been developed as a proposal to help companies who prefer full package production.

Abstract:
Det som ska undersökas i denna fallstudie är ifall visualisering av studerad tid kan öka motivationen hos en högskolestudent att studera på högskola. I denna uppsats definieras studietillfällen som schemalagda föreläsningar och övningar, eller självorganiserade studiepass. Kopplingen mellan motivation och visualisering av tid lagt på träning i gym har tidigare undersökts. Vi bygger vidare på det och undersöker ifall det finns ett liknande samband med mängden tid nedlagd på studier och motivationen att studera vid högre utbildning. Frågan är av intresse för främst utvecklare av lärplattformar, då ifall att fallstudiens resultat skulle tyda på att visualisering av tid nedlagt på studier orsakar en ökad motivation skulle det vara värdefullt att implementera i lärplattformar. Vidare, är frågan av intresse för studenter eftersom det skulle kunna öka deras studiemotivation. Fallstudien inleddes med att 28 studenters motivation mättes, för att få fram ett referensvärde. Därefter fick studenterna under en tvåveckorsperiod dagligen logga den tid de lagt på studier. Utöver det fick studenterna dagliga uppdateringar med stapeldiagram som visuellt representerade den loggade tid de dagligen lade ner på sina studier. Därefter mättes deras motivation återigen, som sedan jämfördes med den inledande mätningen. Resultatet visade att det fanns en signifikant skillnad i två av de sju motivationsskalorna i “Academic Motivational Scale”, den inre motivationen att prestera och den yttre introjicerade motivationen. Detta styrker tidigare studier som visat en koppling mellan visualisering av en elevs nedlagda tid på avklarade moment och elevens prestation i skolan.<br>This case study aims to examine if a visualization of undergraduate students’ learning sessions can increase their motivation to study. Previous studies have shown that there is a correlation between motivation and visualization of time spent on, for example, training in gyms. Consequently, this case study aims to expand on this subject and examine if there is a similar correlation in time spent on studying and the motivation to study in higher educational settings. This question is mainly of interest for developers of learning management systems, such as online course platforms, since if the case study results show that there is an increase in motivation caused by a visualization of time spent studying it would be of value to implement in their learning management systems. Furthermore, this question is of interest for students since it could increase their motivation to study. The case study was initialised by measuring and evaluating 28 undergraduate students’ motivation, to calculate a reference value. The students were then asked to log their study sessions each day and they were given daily updates based on their loggings of their time spent studying during two weeks, with visual bar charts. The case study finished by re-evaluating the motivation of the students and comparing it to the initial measurement. The results showed that there was a significant difference in 2 of the 7 motivational categories of the employed “Academic Motivational Scale”, namely the intrinsic motivation towards accomplishment, and the extrinsic introjected motivation. This further validates previous studies which shows a connection between visualising a students total time spent on accomplished course modules.

Abstract:
Ce manuscrit présente une analyse des champs électromagnétiques induits dans les tissus biologiques par les nouveaux usages en télécommunication ainsi que les nouvelles technologies du type UWB. Pour les nouveaux usages, les terminaux se trouvent de plus en plus proches du buste. Ce positionnement doit être pris en compte par les normes. La composition du buste est différente d'une personne à l'autre. Pour cela une étude sur l'influence de la puissance absorbée en fonction de la composition de la personne est menée. Cette étude servira à déterminer un facteur correctif pour valider l'utilisation du liquide équivalent de la tête pour l'étude de la conformité des terminaux près du buste. De plus une nouvelle approche basée sur de l'homogénéisation de tissus et destinée à réduire le volume et le temps de calculs dans les problèmes de dosimétrie numérique sera présentée pour la méthode de la FDTD. Avec les nouvelles technologies comme l'UWB pour des applications dites BAN, les études sont plus en relation avec l'influence du corps sur la propagation du signal. D'un point de vue numérique, il a été nécessaire de trouver des méthodes numériques comme la FDTD pour des signaux UWB. Des mesures dans le cas d'un réseau BAN ont été réalisées.

Abstract:
When designing visual charts, effective color coding can help users access data information faster and more accurately. Colormaps are a commonly used method for scalar data visualization，which are usually designed using algorithmic techniques. However, the effectiveness of colormaps in mapping data to colors in visualization charts is not clear at present. In order to evaluate the effectiveness of colormaps application in visualization charts, this paper takes four basic visualization charts (bar chart, pie chart, scatter chart, and line chart) as the research object, and takes task completion time and accuracy rate as the index, quantitatively analyzing the application of blue, coolwarm, viridis, and jet in visualization charts. In addition, the Likert scale method was used to understand the subjective perception of users of the color maps.The results showes that the use of different colormaps had no significant effect on the participants' response time and correctness in completing the bar chart task, and a very significant effect on the pie and scatter charts. Participants were most accurate and took the shortest time on the graphs coded with viridis. The longest time was spent on the chart coded with blue and the accuracy was lower. The results of the Likert scale assessment showed that users found blue to be the least easy to read and the least aesthetically pleasing, and jet to be the most aesthetically pleasing and easy to read.

Abstract:
The mobility is analyzed for the 4R1P-type planar closed-loop five-bar linkages using characteristics charts and four-bar Grashof criterion by introducing the virtual link. Based on dimensional relations of the three RR-type links, the five-bars are divided into three categories: Class I, Class II and Class III. Class I satisfies rmax &amp;lt; rmid + rmin, Class II satisfies rmax &amp;gt; rmid + rmin and Class III holds the equality. In the characteristics charts, Class I has a circular slide reachable range with two Grashof regions and two non-Grashof ones separated by three Grashof boundaries C1, C2 and C3, as well as one structure boundary B3; Class II has a ringed range with one Grashof region and two non-Grashof ones separated by the void boundary A1 instead of C1, two Grashof boundaries C2 and C3, as well as B3; and Class III has a circular range with three regions separated by C2, C3 and B3. From the four-bar Grashof criterion, the five-bars have two fully revolute joints at the Grashof regions while no such joints at the non-Grashof regions. Specially, the five-bars have Grashof change points at the Grashof boundaries and keep in line at A1 and B3. Each class includes further sub-classes. Several cases are illustrated for the applications.

Abstract:
The Devonian successions in northeastern Manitoba and northern Ontario are integrated in a single stratigraphic framework. To the north, in the offshore Hudson Bay Basin, stratigraphic nomenclaturesare unified and correlated with the successions to the south. The carbon stable-isotope (d13CVPDB) trends for Devonian carbonate rocks are used for regional correlations and are compared with global Devonian isotope trends. Local and global d13CVPDB trends are used to evaluate the position of the Silurian-Devonian boundary in the Hudson Bay Platform. The Devonian succession of the Hudson Bay Platform belongs to the Kaskaskia Sequence and compares with similar carbonate-evaporite successions of the adjacent Williston and Michigan basins. In these basins, two episodes of roughly coeval reef development are present (Emsian-Eifelian and Givetian), with corals and stromatoporoids as main framework constituents. The Hudson Bay Platform reefs and dolomitized facies exhibit significant porosity and have the potential to form hydrocarbon reservoirs, with intervals bearing direct and petrophysical evidence of hydrocarbon charge.
