In this paper, we present and evaluate the performance of a dynamic dual-link wideband multiple-inputmultiple-output (MIMO) channel sounder. The channel sounder can simultaneously measure two wideband dual-polarized links, each with a MIMO matrix size of 30 × 30 and 30 × 32. Multilink MIMO systems, including multiuser and cooperative MIMO, are essential parts of future high-throughput wireless local area networks and fourth-generation cellular systems. To fully understand such systems, the dynamic characteristics of multilink MIMO channels have to be measured. In this paper, we present a channel sounder that enables such measurements, including double-directional parameter estimation possibility for both links. The presented dual-link MIMO channel sounder does not suffer from the deficiencies of previous virtual multiusermeasurement systems. Furthermore, system analysis and sample results from a measurement campaign with this channel sounder at 5.3 GHz in an indoor office environment are presented. © 2010 IEEE.

The changes facing industries are necessitating a concomitant change in university curriculum. Before instigating a reform, however, education providers need to acquire an understanding of the most pertinent development needs essential for filling industrial competence gaps. The Language Centre at the Helsinki University of Technology in Finland set out to respond to the emerging competence demands by examining industrial requirements through previous research and stakeholder analyses. Surveys conducted among employers and students corroborated a need to shift focus towards oral communication abilities. More specifically, university education needs to address interaction skills essential in meetings and managerial tasks. As a result, a so-called integrated language course was designed and piloted to train students into multi-disciplinary, culturally and ethically aware communicators who possess leveraged self-leadership and managerial abilities. 'Organisational Communications' integrates substance matters such as finance, strategy, leadership and ethics into a language course, while harnessing the English language as a tool. Course methodology is based on project- and problem-based learning and situational learning, rooting the students in real working life by imitating authentic corporate cases and industrial contexts. The course aims to provide the students with preparedness, ability and mindset to deal with working life challenges and ways of working while applying their specialist discourse, that is, the appropriate industrial jargon and linguistic practices. The learning outcomes and student feedback from this course indicate that the pedagogy in use in this experiment, drawing from exercises emulating authentic, industrial problems, offers an effective method of preparing students for working life requirements. © 2010 SEFI.

Recently, a new method based on FT-Raman spectroscopy was proposed to determine cellulose I crystallinity. It was reported that in the Raman spectrum of cellulosic materials the peak intensity ratio of 380 and 1,096 cm -1 bands can be used to determine cellulose crystallinity. In that study, Raman crystallinities of the calibration set Whatman CC31 samples were found to be greatly correlated with the WAXS data (Segal-WAXS-21°; coefficient of determination R2 = 0.98). Average standard error calculated from replicate Raman acquisitions indicated that the Raman crystallinity model was highly reliable. In the present investigation, the Raman and WAXS methods were applied to nanocrystalline and nanofibrillated celluloses. Calculated crystallinities by the two methods were found to be significantly different.

The paper presents a structural design procedure based on multi-objective optimisation and using a decision-support algorithm to Identify the competitive optimum. The procedure is applied to a chemical product tanker. In addition to the rule compliance under service loading, optimisation Is performed with respect to the ship weight, production cost or service life. Appropriate assumptions and simplifications are proposed for not yet known structural solutions or loading conditions. Objectives of the stakeholders are identified in interviews. The paper studies the influence of various objectives on the resulting structural alternatives. © 2010 Institute of Ship Technology and Ocean Engineering.

This paper surveys a collection of sample applications for networked user-centric context-aware embodied music listening. The applications have been designed and developed in the framework of the EU-ICT Project SAME (www.sameproject.eu) and have been presented at Agora Festival (IRCAM, Paris, France) in June 2009. All of them address in different ways the concept of embodied, active listening to music, i.e., enabling listeners to interactively operate in real-time on the music content by means of their movements and gestures as captured by mobile devices. In the occasion of the Agora Festival the applications have also been evaluated by both expert and non-expert users. © Institute for Computer Sciences, Social-Informatics and Telecommunications Engineering 2010.
