Kompatibilitätsanalyse dynamischen Verhaltens von integrierten Automobil-SteuergerätenGlockner, Matthias, Fuchs, Maximilian, Macht, Michael 08 June 2007 (has links)
In Premium-Fahrzeugen werden derzeit ca. 60-70
Steuergeräte (SG) verbaut. Steuergeräte sind
„eingebettete Systeme“ und stellen die zentralen
Rechen- und Steuereinheiten für die elektrischen
und elektronischen Systeme im Fahrzeug dar. Mit
Hilfe der Steuergeräte, die über Bus-Systeme (z.B.
CAN-Bus) miteinander vernetzt sind, können
komplexe Funktionen realisiert werden. Das Motor-
Steuergerät ist eines der bekanntesten.
Der steigende Innovationsgrad im Elektrik- / Elektronik-
Umfeld zwingt die Autohersteller, in immer
kürzeren Zeitabständen, neue Steuergeräte mit
höherer Rechenleistung und neuen Funktionen zu
entwickeln. Aufgrund der steigenden Anzahl von
Steuergeräten, spielt deren Rückwärtskompatibilität
eine immer wichtigere Rolle.

Verteilt agierendes System zur Bereitstellung von geometrie- und bild-basierten Approximationen für das Multiresolution RenderingHilbert, Karsten 07 April 2010 (has links)
In dieser Arbeit wird ein applikationsunabhängiges Reduktionssystem entworfen, das selbstständig und effizient für die ihm übergebenen Modellteile in allen Betrachtersituationen aus einem möglichen Spektrum von geometrie- und bild-basierten Approximationsformen jeweils die geeignete Approximation generiert, deren Komplexität möglichst gering ist und bei deren Verwendung ein Szenenbild erzeugt werden kann, dessen Bildfehler die vom Nutzer vorgegebenen Schranken nicht überschreitet. Das System nutzt bild- und geometrie-basierte Approximationsformen für unterschiedliche Bereiche im Sichtvolumen des Betrachters.
Nailboards sind die benutzten bild-basierten Approximationen. In dieser Arbeit werden neue Nailboardarten vorgestellt, die für die Approximation von semi-transparenten Objekten und von dynamisch beleuchteten Objekten effizient verwendet werden können. Die vorgestellten Erzeugungs- und Darstellungsmethoden nutzen die Fähigkeiten der aktuellen Hardware intensiv aus, um die Nailboards im Echtzeitkontext nutzbar zu machen.
Texturierte, sichtabhängige geometrie-basierte Approximationen werden aus einem texturierten Viewdependent Progressive Mesh (VDPM) gewonnen. In dieser Arbeit wird eine effiziente Methode zur Erzeugung von VDPM vorgestellt, aus der Approximationen mit optimal angepassten Parameterkoordinaten gewonnen werden können, ohne dass ein der VDPM-Erzeugung nachgeschalteter Optimierungsschritt der Parameterkoordinaten aller im VDPM kodierten Approximationen notwendig ist. Die Erzeugung der notwendigen Texturen erfolgt unter Nutzung einer schnellen Parametrisierungsmethode und hardware-gestützter Methoden zur Erzeugung dicht gepackter Texturatlanten.
Durch die Kombination von selektiven Zugriffsmethoden auf TFGR mit effizienten Randanpassungsmethoden, wird erstmals ein effizientes und qualitativ hochwertiges Multiresolution Rendering mittels TFGR ermöglicht. Aus dem TFGR werden texturierte sichtunabhängige Approximationen gewonnen.
Zur echtzeitfähigen, vollautomatischen Erzeugung aller drei Approximationsformen wird in dieser Arbeit ein Reduktionssystem vorgeschlagen, das diese Approximationsformen verteilt generiert. Für eine effiziente Kommunikation innerhalb dieses Systems werden entsprechende Kompressions-, Caching- und State-Differencing-Mechanismen vorgeschlagen. Lastverteilungsmechanismen sichern eine effiziente Ausnutzung der zur Verfügung stehenden Ressourcen ab. / In this thesis, an application-independent system for the distributed generation of object approximations used for multi-resolution rendering is proposed. The system generates approximations of objects of a scene sent to him in an efficient and fully automatic manner. The system is able to generate different kinds of geometry-based and image-based object approximations. For each given objects of a scene it generates that kind of approximation that is suitable for the current view. That means that its complexity is minimal and that it causes an error in the image generated with this approximation that does not exceed a user-specified threshold.
Nailboards are image-based approximations that approximate objects whose size is small compared to the whole scene. In this thesis new kinds of nailboards are presented which can be used efficiently for the approximation of semi-transparent objects and objects in scenes with a dynamic illumination. Capabilities of current graphics hardware are intensively used to generate and render all kinds of Nailboards in real-time.
So-called textured view-dependent progressive meshes (VDPM) are used as view dependent geometry-bases approximations for objects whose size is large compared to the whole scene. In this thesis an efficient method for generating VDPM is presented. This method allows the extraction of approximations with optimally adapted texture coordinates without the necessity of an separate optimization step for the texture coordinates in the generation procedure. The textures necessary for the compensation of detail loss are generated using a fast parameterization method from Yoshizawa. The generation of texture atlases is done hardware-accelerated.
Further on a hardware-accelerated method for hardware-accelerated multi-resolution rendering using multi chart geometry images (MCGIM) is presented. Out of the MCGIM view-independent geometry-based approximations are extracted.
Finally a system for the distributed generation of object approximations is proposed. It generates all three kinds of approximations fully automatic and almost in real time. For an efficient communication within this system suitable compression, caching and state-differencing mechanisms are proposed. Load balancing mechanisms ensure efficient utilization of available resources.

En studie av metoder för effektivisering av bulklager : En fallstudie på pelletstillverkande verksamhetWalldén Cerna, Felicia January 2020 (has links)
Lagerhantering avser aktiviteter som mottagning av varor, inlagring, lagring, orderplockning, omlagring, sortering och frakt. Enligt tidigare studier, av bland annat Drury (1988), uppstår 55% - 60% av lagrets kostnader i orderplockning och omlagring. Idag finns teorier och modeller om hur lagerhantering kring orderplockning och omlagring kan optimeras. Dock behandlas bulklager sällan i forskning eller litteratur. Detta arbete hade således i syfte att undersöka vedertagen teoris anpassningsförmåga på en verksamhet med bulklager. Studien har uppfyllt syftet genom en fall- och litteraturstudie med både kvalitativa och kvantitativa tillvägagångssätt i form av intervjuer och observationer. Lagerutformning och lagerstyrning kan med fördel ses som grundläggande metoder som förutsätter effektivitetsutveckling inom plockning och omlagring i bulklager. Metoder som MUDA och 5S skapar förutsättningarna att identifiera, upprätthålla och genomföra effektivitetsförbättringar. De vedertagna metoderna som studerats kunde genom observation och intervju konstateras som implementerbar eller icke implementerbar. Som sammanfattning kunde en övergripande mall av metoderna sammanställas där det gemensamt och separat kunde bidra till effektivisering. Fallföretaget kunde förses med förbättringsförslag som rekommenderas att införas i både mindre etapper och under större, mer omfattande projekt. / Inventory management refers to activities such as receiving goods, storing, in storage, order picking, rearranging, sorting and shipping. According to previous studies, by Drury (1988), 55% - 60% of the warehouse costs incur in order picking and rearrangement. Today there are theories and models on how inventory management around order picking and rearrangement can be optimized. However, bulk stocks are rarely addressed in research or literature. Thus, this work was aimed at examining the adaptive theory of customary methods in a business with bulk storage. The study has fulfilled its purpose through a case and literature study with both qualitative and quantitative approaches in the form of interviews and observations. Inventory design and inventory control can advantageously be seen as basic methods that require efficiency development in picking and rearranging in bulk storages. Methods such as MUDA and 5S create the conditions for identifying, maintaining and implementing efficiency improvements. The customary methods studied could, through observation and interview, be found to be implementable or non-implementable. In summary, an overall template of the methods could be compiled where they could jointly and separately contribute to efficiency improvements. The studied company could be provided with improvement proposals that are recommended to be introduced in both smaller stages and during larger, more extensive projects.

Text complexity visualisations : An exploratory study on teachers interpretations of radar chart visualisations of text complexity / Visualisering av textkomplexitet : En utforskande studie kring lärares tolkningar av radardiagramsvisualiseringar av textkomplexitetAnderberg, Caroline January 2022 (has links)
Finding the appropriate level of text for students with varying reading abilities is an important and demanding task for teachers. Radar chart visualisations of text complexity could potentially be an aid in that process, but they need to be evaluated to see if they are intuitive and if they say something about the complexity of a text. This study explores how visualisations of text complexity, in the format of radar charts, are interpreted, what measures they should include and what information they should contain in order to be intelligible for teachers who work with people who have language and/or reading diffi- culties. A preliminary study and three focus group sessions were conducted with teachers from special education schools for adults and gymnasium level. Through thematic analysis of the sessions, five themes were generated and it was found that the visualisations are intelligible to some extent, but they need to be adapted to the target group by making sure the measures are relevant, and that the scale, colours, categories and measures are clearly explained. / Det är både en viktig och krävande uppgift för lärare att hitta lämplig textnivå för elever med varierande läsförmågor. Radardiagramsvisualiseringar av textkomplexitet kan poten- tiellt stötta den processen, men de måste utvärderas för att undersöka om de är intuitiva, vilka mått som bör inkluderas samt om de säger något om komplexiteten av en text. Den här studien utforskar hur visualiseringar av textkomplexitet i form av radardiagram tolkas, vilka mått de bör inkludera samt vilken information de bör innehålla i syfte att vara begripliga för lärare som jobbar med elever med språk och/eller lässvårigheter. En förundersökning och tre fokusgruppsessioner utfördes, med lärare från särgymnasium och särvuxskolor. Efter tematisk analys av data från fokusgrupperna genererades fem teman. Reultaten visade att visualiseringarna var begripliga till viss del, men de behöver anpassas till målgruppen genom att se till att måtten är relevanta samt att skalan, färgerna, kategorierna och måtten är tydligt förklarade.

Developing an Analysing a Web Application made for Teachers to Evaluate Students' Performance : Utveckling och analys av en webbapplikation för examinatorers analys av elevers lärandeHultqvist, Andreas, Hultqvist, Tobias January 2021 (has links)
The need to learn programming increases as more jobs require basic programming skills and computer knowledge. Compulsory school is adding programming to the curriculum, which leads to challenges due to both teachers and students are new to this subject. Even at the university level some students get in touch with programming for the first time in their lives. This thesis aim to develop a web application that can be used by teachers as a reliable and informative tool when evaluating the learning process of its students, by combining data collected through user interactions while solving programming related puzzles in Python, with answers from periodic self-evaluation surveys. The study shows that the web application can be seen as a valid tool when evaluating the students' learning process.
