Für ereignisgesteuerte Systeme mit mehrdimensionalen Bewegungsabläufen wurde im Fachausschuss 4.12 "Bewegungssteuerungen für Be- und Verarbeitungsmaschinen" der VDI/VDE-Gesellschaft Mess- und Automatisierungstechnik (GMA) die VDI/VDE-Richtlinie 3684 "Beschreibung ereignisgesteuerter Bewegungsabläufe mit Funktionsplänen" als interdisziplinär verständliches und anschauliches Dokumentationsmittel und Entwurfswerkzeug erarbeitet. Mit der Blockbibliothek Funktionsplan auf Grundlage der in der Richtlinie 3684 vorgeschlagenen Systembeschreibung ist ein durchgängiger Entwurfsweg bis zur Überprüfung des Systemverhaltens ereignisgesteuerter Systeme mittels Simulation einschließlich frühzeitiger Erkennung von Fehlern im Entwurfsprozess und Kodegenerierung möglich. Die FUP Blockbibliothek liegt als Erweiterungs-Blockbibliothek für SIMULINK vor und wurde hinsichtlich ihrer wesentlichen Eigenschaften zur Simulation von ereignisgesteuerten Prozessen speziell in mechatronischen Systemen entwickelt. Die Blockikonen gewährleisten schon nach kurzer Einarbeitungszeit einen sicheren Einsatz der Blöcke, damit kann auf Blockkürzel im Sinne der Richtlinie zwecks besserer Übersichtlichkeit verzichtet werden. Zweisprachige Blockhilfen sind in Version 3.1 für alle Blöcke on-line verfügbar. Graphisch programmierte Funktionspläne können mittels Toolbox Funktionsplanprüfung vorzugsweise über GUI, bei Bedarf auch durch MATLAB Skripte, auf Eingabe- und Programmierfehler geprüft werden. Die Prüfung kann wahlweise vollständig oder auf ausgewählte Fehler erfolgen. Ergebnisausgaben sind entweder in gestraffter Form oder ausführlich einschließlich von Hinweisen möglich. Überprüft werden können Parameter (z.B. Zustands- u. FUP-Nummern, Variablen, Fehlerbehandlung), Syntax (vgl. Richtlinie), Sackgassen (erste/alle) und Rückführschleifen (Entkopplung). Hybride Funktionspläne sind in Echtzeitkode für eine Zielhardware übersetzbar. Voraussetzung ist ein Standard ANSI C Compiler. Die Blockbibliothek Funktionsplan ist eine kostengünstige, richtliniennahe Alternative und ermöglicht eine vom Normalablauf separate, graphisch programmierte Fehlerbehandlung ohne Verlust an Übersichtlichkeit. Die Anwendung der Blöcke wird durch 11 Beispiele veranschaulicht. / The department committee 4.12 "Motion control of machine tools and processing machines" of the VDI/VDE Society for Measurement and Automatic Control (GMA) has established a manufacturer-neutral guideline No. 3684 for event-driven systems with multi-dimensional motion sequences. This guide-line is entitled "Description of event-driven motion processes by function charts" and constitutes a graphically clear design and documentation tool that is well-suited for interdisciplinary application. The block library Function Chart has been defined based on system descriptions suggested in guideline 3684. This library makes available a uniform design procedure. It covers the documentation, the behaviour test of event-driven systems by means of simulation including the early detection of design process faults, the test of realization variants as well as the code generation. Block library Function Chart is an add-on library for SIMULINK. With regard to its essential features it has been developed for the design, simulation, code generation and the description of event-driven systems especially for mechatronics, mechanical and electrical engineering. The created block icons make it possible to get familiar with add-on library Function Chart within a short period of time whereupon block mnemonics may be hidden in order to get a high graphical clearness and to fulfil the requirements of the guideline. Versions 3.1 bilingual on-line block help is available for all blocks. Graphically programmed function charts may be checked for input and programming errors preferably with help of Toolbox "Function Chart Check" by means of GUI's and if necessary also by MATLAB scripts. The check may be done completely or alternatively for selected errors. Output of result is possible either in detail inclusively eventual hints or in shortened form. A function chart may be checked for parameter errors (e.g. state and FUP numbers, variables, error handling), syntax errors (see guideline), dead ends (first or all) and uncoupled loops (arithmetic loops). Standard ANSI C compiler availability stands for a precondition for real time code generation. The block library Function Chart offers a reasonable alternative and allows separate motion error handling sequences which are separated from normal motion sequences without any loss of a well-ordered graphical arrangement. Currently 11 examples demonstrate the application of the blocks.

Werkzeuge für Entwickler Eine Vielzahl von kleinen Helfern erleichtert den Programmierern die Arbeit. Neben make, configure und kommandozeilenorientierte Compiler treten mächtige Entwicklungswerkzeuge, mit denen sich in Windeseile Oberflächen erstellen lassen. In diesem Vortrag werden der allgemeine Aufbau eines Software-Projektes unter Unix erläutert und die Leistungsfähigkeit der Entwicklungs-Tools am praktischen Beispiel vorgeführt.

A pragmatic method for selecting components and devices from a database or parameterized models is developed in this thesis. The quantitative framework presented here is sufficiently general to accommodate an entire device assembly, a component, or a sub-assembly. The details pertaining to a device or a component are classified into three sets of variables: (i) user-specifications, s (ii) device parameters, p , and (iii) device characteristics, c . Functional, practical, and performance-related attributes that a user can provide comprise user-specifications. Since, most often, a specification cannot be specified as a single number, we allow the user to enter a range with lower and upper bounds. Device parameters comprise the geometry and material properties, and device characteristics include functional requirements and performance criteria. Thus, for a device, all its functional and utility attributes are contained in the union of sets s and c , whereas the geometry and the material properties are in set p . The equations governing the physical behavior of the device are written in terms of s , p , and c . These equations may sometimes be readily available; when they are not, it may be necessary to formulate them as required. By solving the governing equations along with the inequalities that arise from the lower and upper bounds on s , we obtain feasible ranges on p and c . Then, for any pair of device characteristics, a 2D feasible map is drawn, to visually portray the consequences of user-specifications. If the feasible map is null, small, or large, it indicates that the user-specifications are infeasible, stringent, or there is much scope for design, respectively. This can be inferred even before the designs are considered. Juxtaposed on the feasible map are points or lozenges corresponding to the quantitative attributes of the entries in the database. The ones that lie inside the feasible map can be reckoned as meeting the user-specifications and thus, enabling selection. On the other hand, if there is no database or none of the devices in the database lie inside the feasible map, we can identify the feasible ranges of all the design parameters for every point inside the feasible map. This information is useful to the designer to redesign and arrive at feasible designs by using parameterized models of the device. A Graphical User Interface (GUI) is developed to facilitate the user-interaction. The utility of the selection framework is demonstrated with a variety of case-studies including miniature pumps, heat pulse-based soil-moisture sensors, springs, flywheels, compliant mechanisms, micromechanical suspensions, etc. The latter two use kineto-elastic characteristics of deformable components. The framework, when used for materials selection, can be seen as an extension of Ashby’s materials selection method. This is also illustrated with two examples.

Creating immersive experiences for virtual reality (VR) presents new design opportunities and challenges that do not appear when creating experiences on a screen. Creating prototypes and exploring concepts in VR is today limited to professionals with previous knowledge in 3D application development, and testing 3D experiences requires the usage of an Head-Mounted Display (HMD), which forces professionals to switch medium from the computer to an HMD. With new advances in this field, there have to be new solutions to these challenges. The goal of this thesis is to explore how VR technology can be utilized in the experience design process for VR. This is achieved through a literature study and conducting expert interviews, followed by a hardware evaluation of different HMDs and concept creation using rapid prototyping. From the interviews, a number of issues could be identified that correlates with the research from the literature study. Based on these findings, two phases were identified as suitable for further improvements; Concept prototyping and testing/tweaking of a created experience. Lo-fi and hi-fi prototypes of a virtual design tool were developed for HTC Vive and Google Daydream, which were selected based on the hardware evaluation. The prototypes are designed and developed, then tested using a Wizard of Oz approach. The purpose of the prototypes is to solve some of the issues when designing immersive experiences for HMDs in the suitable experience design phases that were identified by analyzing the interview results. An interactive testing suite for HTC Vive was developed for testing and evaluation of the final prototype, to verify the validity of the concept. Using Virtual Reality as a medium for designing virtual experiences is a promising way of solving current issues within this technological field that are identified in this thesis. Tools for object creation and manipulation will aid professionals when exploring new concepts as well as editing and testing existing immersive experiences. Furthermore, using a Wizard of Oz approach to test VR prototypes significantly improves the prototype quality without compromising the user experience in this medium.

In diploma thesis Open Call I focus on unequal position of artists in current art world in which, despite the transparent practices like open calls, still persists the cult of name, the power of networking and personal recommendation. This topic I artistically process in form of practical artistic intervention, which is close to the tactics of 1:1 scale of Arte Útil - specifically by creation of software tool called Nomin. Its purpose is to support weakened or marginalized groups of artists. Nomin uses properties of email protocol SMTP to allow its users-spectators to send fake self-recommending emails - from email addresses of famous curators to the inboxes various galleries or other art institutions. During development of program Nomin and its technical background (software documentation, web page etc.) I followed the paradigm of free, libre, open source software (FLOSS) and also the methodology of agile software development in order to provide in this gesamtsoftwerk the users-spectators with fully functional, user-friendly software and give them possibility to influence further development of Nomin or directly participate on it. Created artwork is thus not a single artefact but rather a set of interconnected objects and practices grounded in the network of social bonds and behaviours which balances on the edge of institutional critique, useful art, participatory art and collective performance.

This thesis aims to implement methods for recording EEG data obtained with the neural activity sensor OpenBCI Ultracortex IV headset. It also describes neurofeedback, methods of obtaining data from the motor cortex for further analysis and takes a look at the machine learning algorithms best suited for the presented problem. Multiple training and testing datasets are created, as well as a tool for recording the brain activity of a headset-wearing test subject, which is being visually presented with cognitive challenges on the screen in front of him. A neurofeedback demo app has been developed, presented and later used for calibration of new test subjects. Next part is data analysis, which aims to discriminate the left and right hand movement intention signatures in the brain motor cortex. Multiple classification methods are used and their utility reviewed.
