A complete MaCon project in 4:30 minutes

The MaCon approach covers a wide range of engineering tasks for manufacturing systems, from requirements analysis, to system design, to component and system test. Understanding all aspects and their relationships is difficult, which is why I decided to produce another YouTube video showing a complete MaCon project in fast motion. Note that the video is based on a previous version of the MaCon tool, thus the graphical user interface looks slightly different than before.

MaCon YouTube Video

In the last days, I prepared a YouTube video demonstrating MaCon: A tool for consistent cross-discipline conception of manufacturing systems. The video explains the MaCon user interface and shows advanced features such as scenario-based testing and test report generation. The tool represents an integral part of my dissertation work at the Technische Universitaet Muenchen.

Meet EnergyCity - A Virtual Testbed for Smartness

To smooth the way for smart energy systems we have been working on a virtual testbed for deploying and testing control strategies: EnergyCity. This article shows a first video of the testbed including advanced 3D and regular chart visualization - all in the web browser.

Visualization Studio for Systems Engineers

Seeing is understanding. This is especially true when engineering the structure and behavior of complex systems. Understanding whatever models you built is the first step towards trusting and improving them. To support model understanding we worked on a prototype for comprehensive model visualization. A YouTube video demonstrates first visualization results.

How to Scale Refrigerator Powering Strategies

When it comes to an array of heterogeneous refrigerators, control optimization becomes a real challenge. In this article I demonstrate how a possible strategy could look like for an array of 20 refrigerators. Solar power is provided in form of a Gaussian with mean 1pm and covariance of 7 hours.

Visualizing our Smart Grid Simulation

At ICSE I presented our initial model for simulating the smart grid including both physical and software components. To help developers analyse their systems we developed a visualization pipeline on top of the model. A first YouTube screencast demonstrates sample visualization output as proof of concept.

First Results on Smart Grid Simulation as YouTube Video

The last weeks my colleagues and I have been working hard on a basic simulation of a household with electric components and control software. We show first results in our latest YouTube video featuring weahter, user interaction, solar panels, a lamp and a refrigerator. The result is a show case for the direction we are working towards, i.e. large scale electric component and software simulation.

Promotional Smart Grid Videos

Currently I am working hard to understand ongoing efforts for revolutionizing the energy supply systems across the globe. In a recent article - a View onto the Energy System - I visualized my current understanding of the domain. In this article I want to point you to two short (< 5 minutes) YouTube videos that provide a nice overview of the domain.

Blog Timeline Widget

The main purpose of a blog is to provide access to articles (HTML documents) organized by date. To reflect this idea I designed a timeline that visualizes the temporal activity on a blog and that can be used as a navigation at the same time. This post contains screenshots and a YouTube video.

Interactive Animated Sitemap

Last summer I had the chance to develop an innovative sitemap widget for the company Le-Tex, which was intended for use at the international book fair in Frankfurt, Germany. The result was a multi-touch capable cross-browser vector graphics and JavaScript based graph navigation control.

From Layout to Animation

In a previous article The Evolution of a Functional Prototype I demonstrated how to transform sketches into prototypes backed by database content and application logic. In this post I explore the options for animation of the user interface to provide smooth transitions between the displayed contents. This interface paradigm is for example used by Apple's products to deliver great user experiences.

JavaScript Physics Simulation

Some time ago I was testing the capabilities of JavaScript and vector graphics toolkits such as SVG (Mozilla Firefox, Opera, Safari) and VML (Microsoft Internet Explorer). One interesting test case was the animation and simulation of physical phenomena such as Newton's law of graviation and impulse. In this article I show results and explain the logic behind the scenes.

Linear vs. Cubic Interpolation

After talking with some non-computer scientists about my previous visualization of cubic interpolation I found out that the concept is difficult to understand if contextual information is missing. Therefore I prepared another video comparing cubic interpolation to basic linear interpolation while hoping that the difference encourages a better intuition and understanding.

3D Cubic Interpolation Video

Cubic interpolation is a popular technique in many branches of computer science. For example, it is used when having a time series of numbers and estimating the intermediate points, for which no dedicated number sample is available. In such situations the idea is to consider the series as a time-continuous function, estimating the function's parameters, and calculating the function value for the desired time point. Hereby, we talk about cubic interpolation if this estimation function uses the time parameter up to the power of three. The effect of this technique is visualized in my newest YouTube video.
