A model to describe biogas transport costs in a regional grid is presented. In the model biogas is collected to a central location by transport through dedicated pipelines. Costs have been calculated for two different lay-outs of the grid i.e. star and fishbone lay-out. The costs depend on the covered area and the size of the digesters. Model results show that in a star layout transport costs for small scale digesters are much higher than costs for large scale digesters and costs in a fishbone lay-out are lower than costs in a star lay-out.

Weblogs en wiki's zijn lichtgewicht applicaties en kunnen los van elkaar ingezet worden, maar ze gaan ook heel goed samen. Er is sprake van een duidelijke samenhang tussen de functionaliteiten van weblogs en wiki's. Weblogs zijn namelijk uitermate geschikt voor het communiceren van actuele dynamische content (nieuws), een wiki kan daarbij fungeren als aanvullende documentatie- of naslagruimte (achtergronden). En dan is er, niet te vergeten, nog het rss-protocol. Dit werkt als bindmiddel voor de content van beide systemen, het is de centrale schakel tussen zenders en ontvangers van informatie. Wiki's worden door de enorme hype rondom weblogs enigszins overschaduwd, maar zeker in bedrijfsomgevingen zijn wiki's uitermate geschikt voor collectieve taken.

In sports, inertial measurement units are often used to measure the orientation of human body segments. A Madgwick (MW) filter can be used to obtain accurate inertial measurement unit (IMU) orientation estimates. This filter combines two different orientation estimates by applying a correction of the (1) gyroscope-based estimate in the direction of the (2) earth frame-based estimate. However, in sports situations that are characterized by relatively large linear accelerations and/or close magnetic sources, such as wheelchair sports, obtaining accurate IMU orientation estimates is challenging. In these situations, applying the MW filter in the regular way, i.e., with the same magnitude of correction at all time frames, may lead to estimation errors. Therefore, in this study, the MW filter was extended with machine learning to distinguish instances in which a small correction magnitude is beneficial from instances in which a large correction magnitude is beneficial, to eventually arrive at accurate body segment orientations in IMU-challenging sports situations. A machine learning algorithm was trained to make this distinction based on raw IMU data. Experiments on wheelchair sports were performed to assess the validity of the extended MW filter, and to compare the extended MW filter with the original MW filter based on comparisons with a motion capture-based reference system. Results indicate that the extended MW filter performs better than the original MW filter in assessing instantaneous trunk inclination (7.6 vs. 11.7◦ root-mean-squared error, RMSE), especially during the dynamic, IMU-challenging situations with moving athlete and wheelchair. Improvements of up to 45% RMSE were obtained for the extended MW filter compared with the original MW filter. To conclude, the machine learning-based extended MW filter has an acceptable accuracy and performs better than the original MW filter for the assessment of body segment orientation in IMU-challenging sports situations.

Het JeugdSynergiePlan beschrijft de wijze waarop er bij verenigingen door een effectieve samenwerking tussen de verschillende stakeholders meer kan worden bereikt voor iedereen. De belangrijkste samenwerkende partijen (stakeholders) bestaan uit de leden, de ouders en vrijwilligers, de verenigingen, de bonden, de overheid, de zorgverzekeraars, de sponsors en de zakelijke dienstverleners. Speerpunt vormt de kwetsbare groep van middelbare scholieren voor wie er in praktijk te weinig aandacht bestaat. Door de samenwerking waarbij de partijen gebruik gaan maken van elkaars sterktes en kansen ontstaat er synergie: het effect van de samenwerking is groter dan wat iedere partij afzonderlijk had kunnen bereiken. In het rapport komen theorie en praktijk bij elkaar. De theorie inzake synergie wordt op een unieke manier beschreven en verduidelijkt. Ook staan er veel unieke oplossingen beschreven in het rapport waarmee synergie in praktijk kan worden uitgevoerd. Er wordt meer bereikt en er worden kosten bespaard. Het rapport biedt dan ook grote winstmogelijkheden voor de leden, voor de verenigingen, voor de overheid, de jeugdzorg, het onderwijs, voor de zakelijke dienstverlening; kortom de hele maatschappij. Belangrijke zaken komen eerst en daarom gaat welzijn boven welvaart en een pro-actief beleid gaat voor restrictief beleid. Dat kan allemaal met dit model! Vast staat dat de jeugd een enorme potentie heeft voor velen. Hier groeien de toekomstige winnaars voor 2028, maar hier groeien ook de toekomstige werknemers, politici, uitvinders. Doorzettingsvermogen, discipline, ijver en sociale vaardigheden vormen aspecten die we in het verenigingsleven kunnen stimuleren. Maatschappelijke doelstellingen als integratie, armoedebeleid en gezondheid, zijn daarmee te sturen vanaf het speelgras en het honk. Het kind en de vereniging kunnen hiermee uitgroeien tot het maatschappelijk goud en het olympisch vuur.

Green data centres are the talk of the day. But who in fact is involved in developing green data centres? What is their contribution? And what does this contribution constitute in practical terms? This article states which stakeholders are involved in green data centres in the Netherlands, what their involvement is and what effect their involvement has. The article starts by giving the definitions for sustainability and by determining the stakeholders and their possibilities in this field. Next, we examine the actual impact of each stakeholder for arriving at greener data centres. This leads to a number of conclusions for achieving a larger degree of sustainability.

Background: Low-educated patients are disadvantaged in using questionnaires within the health care setting because most health-related questionnaires do not take the educational background of patients into account. The Dutch Talking Touch Screen Questionnaire (DTTSQ) was developed in an attempt to meet the needs of low-educated patients by using plain language and adding communication technology to an existing paper-based questionnaire. For physical therapists to use the DTTSQ as part of their intake procedure, it needs to generate accurate information from all of their patients, independent of educational level. Objective: The aim of this study was to get a first impression of the information that is generated by the DTTSQ. To achieve this goal, response processes of physical therapy patients with diverse levels of education were analyzed. Methods: The qualitative Three-Step Test-Interview method was used to collect observational data on actual response behavior of 24 physical therapy patients with diverse levels of education. The interviews included both think-aloud and retrospective probing techniques. Results: Of the 24 respondents, 20 encountered one or more problems during their response process. The use of plain language and information and communication technology (ICT) appeared to have a positive effect on the comprehensibility of the DTTSQ. However, it also had some negative effects on the interpretation, retrieval, judgment, and response selection within the response processes of the participants in this study. No educational group in this research population stood out from the rest in the kind or number of problems that arose. All respondents recognized themselves in the outcomes of the questionnaire. Conclusions: The use of plain language and ICT within the DTTSQ had both positive and negative effects on the response processes of its target population. The results of this study emphasize the importance of earlier recommendations to accompany any adaption of any questionnaire to a new mode of delivery by demonstrating the difference and equivalence between the two different modes and to scientifically evaluate the applicability of the newly developed mode of the questionnaire in its intended setting. This is especially important in a digital era in which the use of plain language within health care is increasingly being advocated.

Objective: Despite the increasing availability of eRehabilitation, its use remains limited. The aim of this study was to assess factors associated with willingness to use eRehabilitation. Design: Cross-sectional survey. Subjects: Stroke patients, informal caregivers, health-care professionals. Methods: The survey included personal characteristics, willingness to use eRehabilitation (yes/no) and barri-ers/facilitators influencing this willingness (4-point scale). Barriers/facilitators were merged into factors. The association between these factors and willingness to use eRehabilitation was assessed using logistic regression analyses. Results: Overall, 125 patients, 43 informal caregivers and 105 healthcare professionals participated in the study. Willingness to use eRehabilitation was positively influenced by perceived patient benefits (e.g. reduced travel time, increased motivation, better outcomes), among patients (odds ratio (OR) 2.68; 95% confidence interval (95% CI) 1.34–5.33), informal caregivers (OR 8.98; 95% CI 1.70–47.33) and healthcare professionals (OR 6.25; 95% CI 1.17–10.48). Insufficient knowledge decreased willingness to use eRehabilitation among pa-tients (OR 0.36, 95% CI 0.17–0.74). Limitations of the study include low response rates and possible response bias. Conclusion: Differences were found between patients/informal caregivers and healthcare professionals. Ho-wever, for both groups, perceived benefits of the use of eRehabilitation facilitated willingness to use eRehabili-tation. Further research is needed to determine the benefits of such programs, and inform all users about the potential benefits, and how to use eRehabilitation. Lay Abstract The use of digital eRehabilitation after stroke (e.g. in serious games, e-consultation and education) is increasing. However, the use of eRehabilitation in daily practice is limited. As a first step in increasing the use of eRehabilitation in stroke care, this study examined which factors influence the willingness of stroke patients, informal caregivers and healthcare professionals to use eRehabilitation. Beliefs about the benefits of eRehabilitation were found to have the largest positive impact on willingness to use eRehabilitation. These benefits included reduced travel time, increased adherence to therapy or motivation, and better health outcomes. The willingness to use eRehabilitation is limited by a lack of knowledge about how to use eRehabilitation.

On a four-year bachelor course at Inholland University of Applied Sciences in the Netherlands, additional modern language was offered to first-year students studying at three locations. Since each location only had a few students and there was only one language teacher available, across the three locations, lessons were given by the teacher in a ‘hybrid’ classrooms. The teacher was at one location with some students while students from the other two locations would join via live video link. The focus was to develop speaking and listening skills through in-classroom discussion that took place via the video link. Short video news segments in the language were watched live in class. This lead to discussion and practicing the language. Learning support materials were available in the form of a grammar book with an online self-test learning environment. The research group conducted research on this original and creative solution to teaching smaller groups since much could be learned from a practical, didactic and organisational perspective. Several organisational issues influenced the course. And from a pedagogical perspective, this case supported findings from the literature that it is complicated to engage with students live in a classroom while also communicating with students at other locations via a video screen.
