For myself, I am interested in science and in philosophy only because I want to learn something about the riddle of the world in which we live, and the riddle of man's knowledge of that world. And I believe that only a revival of interest in these riddles can save the sciences and philosophy from narrow specialization and from an obscurantist faith in the expert's special skill, and in his personal knowledge and authority; a faith that so well fits our `post-rationalist' and `post- critical' age, proudly dedicated to the destruction of the tradition of rational philosophy, and of rational thought itself.

  • Research Document Number Plate Recognition
    Research Document Number Plate Recognition Francois Ribemont Supervisor: Nigel Whyte December 16, 2011 Contents 1 1 Introduction Number Plate Recognition (NPR) is a software that reads Irish car plate num- bers from pictures. The input of the program is an image, and the output of the program is a text string containing the car plate number. By executing a series of algorithms, the program will be able to take an image as an input and gener- ate the number plate in a text format. For the Figure ??, the output would be: 03MH1847. Figure 1: Irish car plate This software is usually embedded with video cameras. It is mainly used by the police to recognize stolen vehicles or speeding. If, for instance, a car goes too fast on a motorway, some sensors send a signal to the camera, and then a picture is taken. Then it gives the taken pictures to the NPR system, and NPR output the number plate in a text format. Irish car plates respect this format: YY-CC-SSSSSS where YY is a double digit for the year of registration, CC represents the two letters from which county the car has been registered in, and finally SSSSSS is the serial number. This serial number starts from 0 every year, and is specific to a county, meaning that 157 in Dublin is different than in Carlow. All the specifications about Irish car plate 2 regulations, such as the size of characters, thickness of the edges, distances between characters, can be found on the Irish Status Book's website [?].

  • Can Free Software Replace Proprietary Software for Graphic Production? Investigating to Which Extent Free Software Can Be Used for Book and Magazine Production
    Can free software replace proprietary software for graphic production? Investigating to which extent free software can be used for book and magazine production. 2013-04-25 Staffan Melin, D89, [email protected] Master´s thesis in Media Technology, School of Computer Science and Communication at the Royal Institute of Technology, Stockholm, Sweden This work is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 3.0 Unported License. Abstract Free and open source software is widely used. At the same time there are several areas where it is not. One of these is graphic production where the applications from Adobe – Indesign, Photoshop and Illustrator – dominates. In this thesis I start by describing a workflow for graphic production. Next I research the field of free software and put together a set of tools that fit into this workflow. The choices are made on the basis of functionality and how they work together. I then go on to apply these tools to two real world scenarios: production of a book and a magazine. The results show that free software can be used for graphic production without any loss of quality and only minor problems compared to the proprietary tools. A look into future development shows that the bulk of these problems are being taken care of by the open source community. Keywords: free software, open source, proprietary software, graphic production, graphic design, FLOSS, FOSS, layout, libre, Scribus, Inkscape, GIMP, GNOME Color Manager. Sammanfattning Fri och open source programvara används på många områden. Samtidigt finns det många områden där det inte används. Ett av dessa är grafisk produktion där programmen från Adobe – Indesign, Photoshop och Illustrator – dominerar.

  • An Order-Aware Dataflow Model for Parallel Unix Pipelines
    65 An Order-Aware Dataflow Model for Parallel Unix Pipelines SHIVAM HANDA∗, CSAIL, MIT, USA KONSTANTINOS KALLAS∗, University of Pennsylvania, USA NIKOS VASILAKIS∗, CSAIL, MIT, USA MARTIN C. RINARD, CSAIL, MIT, USA We present a dataflow model for modelling parallel Unix shell pipelines. To accurately capture the semantics of complex Unix pipelines, the dataflow model is order-aware, i.e., the order in which a node in the dataflow graph consumes inputs from different edges plays a central role in the semantics of the computation and therefore in the resulting parallelization. We use this model to capture the semantics of transformations that exploit data parallelism available in Unix shell computations and prove their correctness. We additionally formalize the translations from the Unix shell to the dataflow model and from the dataflow model backtoa parallel shell script. We implement our model and transformations as the compiler and optimization passes of a system parallelizing shell pipelines, and use it to evaluate the speedup achieved on 47 pipelines.
