Is XLIFF 2.0 A Successful Evolution? (FEISGILTT 2014 Keynote)Chase Tingley
This is an expanded version of a short talk I previously gave last fall about why localization standards always fail. This time, I applied some of the same analysis to the problems encountered in the past by XLIFF 1.2, as well as the ways in which the upcoming XLIFF 2.0 standard hopefully addresses them. It also discusses new challenges to adoption and includes gratuitous pictures of mole rats.
This talk was the keynote at FEISGILTT 2014 in Dublin.

22 Re-Engineering Traditional Learning Model with Outcome-Based Learning Curv...ijtsrd
This paper presents the design and implementation of an indigenous outcome based 8051 microcontroller training kit. Most of the existing microcontroller training kits available do not have local content, and also have problems with maintenance and repair when they develop faults. Users usually dump these kits when they develop faults due to a lack of trained technical maintenance personnel. This project used components that are locally available to implement an outcome based 8051 microcontroller training kit that is modular and easy to use. In the methodology, the bottom top approach was used to design the individual modules of the kit before fabricating them on a printed circuit board PCB . The user manual was then developed and experiments in it were tested using the developed training kit. The result of the work is an outcome based 8051 microcontroller training kit that meets the National Universities Commission NUC and Council for the Regulation of Engineering in Nigeria COREN standards. It has various modules for the user to practice several 8051 microcontroller programming experiments. The work can be deployed in university laboratories for microcontrollers and embedded systems training. Specifically, there are courses in Mechatronics engineering, FUTO, that can be taught using this kit.

EuropIA 2014 - Analysing the impact of constraints on decision-making by arch...Pieter Pauwels
Architectural design projects are characterised by a high level of complexity. This level of complexity may be attributed to the high number of constraints that apply to architectural design projects. Along with planning, energy performance and fire safety regulations, current designers have to face constraining factors related to budget, acoustics, orientation, wind turbulence, accessibility for the disabled, and so forth. It thus appears that all sorts of restrictions and regulations steer the design process implicitly and explicitly in certain directions as soon as architectural designers aim at satisfying design briefs.
In this research, we aim at analysing the impact of parameters and constraints on the design process. We wish to investigate how designers in practice deal with parameters and constraints. How do they interpret incoming parameters or constraints? Are constraints considered to be limitative (constraining), or are they key reference points in a variety of parametric possibilities? Are constraints omnipresent during the design process or are they considered only until they have been 'resolved'? To make an analysis of the role of constraints and parameters in the design process, we have studied four design sessions in a particular design use case, which will be presented briefly in this paper. In each of these design sessions, the design was not only re-evaluated, but it was also redirected in response to certain constraints that were not met (yet). In analysing these four sessions, we used linkography as a method, because this appeared to be one of the better options to obtain a more quantitative assessment of the design process. The linkography method was combined with an interview of the student design team, in order to check the correctness of our conclusions.
NordDesign2014 - Reasoning processes involved in ICT-mediated design communic...Pieter Pauwels
Conversational interaction is central to architectural design practice. New information and communication technologies (ICT) change the designer’s traditional way of communicating and interacting. In this paper we investigate how communication in the design process might be supported using ICT. With this aim, we study a text-based Skype conversation between a design teacher and a design student. We consider this conversation as part of an architectural design process and analyse it using linkography. From the linkograph analysis, specific features are identified that apply specifically to text-based Skype interactions. We conclude that online text-based Skype interaction can be one of the many possible interactions by means of communication media (sketching, conversation, modelling, and so forth) during the design process, and provides a distinct set of characteristics that might be considered by the designer.

converter/tree/BS) and C++ converter
– Resulting ontologies:

15. Option 1 – Manual modelling from scratch
using an ontology editor
16. 1. Not all IFC restrictions (rules, derive
attributes, functions) available in
ifcOWL => no complete consistency
checking
2. Tedious and error-prone process
limitations
17. Option 2 – Automatic modelling from scratch
using APIs
im = ModelFactory.createDefaultModel();
im.setNsPrefix("ifcowl", ontNS);
im.setNsPrefix("inst", baseURI);
for (int i = 0; i < inst.getList().size(); i++) {
OntClass cl = ontModel.getOntClass(ontNS + typeName);
Resource r = im.createResource(baseURI + typeName + "_" + inst.getLine_num(), cl);
}
18. 1. Not all IFC restrictions (rules, derive
attributes, functions) available in
ifcOWL => no complete consistency

2. Need to build modelling application
anew, relying on a different software
library at the basis
limitations
19. Option 3 – Conversion of existing IFC SPFF Files
Free open file-to-file conversion service: http://smartlab1.elis.ugent.be:8889/IFC-repo/
20. 1. Two distinct applications, two distinct models -> versions can go out of control
2. The converter can become a bottleneck
