Het onderzoek in het artikel is geïnspireerd door de casus 'platooning' uit de Grand Cooperative Driving Challenge. Er is een PreScan®/Sumulink® model opgesteld met daarin twee auto's. De voorste auto volgt een vastgesteld snelheidsprofiel, de tweede auto volgt de eerste auto waarbij de tweede auto de snelheid van de eerste meet met behulp van een AIR-sensor. De besturing van het gaspedaal in beide auto's vindt plaats met Fuzzy Logic Control in plaats van met een klassieke regelaar. Concluderend mag worden gesteld dat in dit verkennend onderzoek gebleken is dat de Fuzzy Logic Control techniek in principe werkt.

In the city of Amsterdam commercial transport is responsible for 15% of vehicles, 34% of traffic’s CO2 emissions and 62% of NOx emissions. The City of Amsterdam plans to improve traffic flows using real time traffic data and data about loading and unloading zones. In this paper, we present, reflect, and discuss the results of two projects from the Amsterdam University of Applied Sciences with research partners from 2016 till 2018. The ITSLOG and Sailor projects aim to analyze and test the benefits and challenges of connecting ITS and traffic management to urban freight transport, by using real-time data about loading and unloading zone availability for rerouting trucks. New technologies were developed and tested in collaboration with local authorities, transport companies and a food retailer. This paper presents and discusses the opportunities and challenges faced in developing and implementing this new technology, as well as the role played by different stakeholders. In both projects, the human factor was critical for the implementation of new technologies in practice.

Met dit document wil ik de lezer een nieuwe invalshoek tonen op mobiliteit (Driving Guidance) en een andere benadering van automotive hbo onderwijs. De wereld om ons heen verandert en deze nieuwe wereld zal een ander type automotive ingenieur eisen. Dit is een korte weergave van een lezing voor de MBO-raad onderafdeling docenten automotive (Onderstructuur Btg MCT). De presentatie is gehouden op Miniconferentie Onderstructuur Btg MCT op 23 april 2010 bij Innovam te Nieuwegein. Kort worden trends op wereldniveau geschetst waarna wordt afgedaald naar het niveau van mijn werkplek. Het pad verloopt via niveau van Nederland, Regio Eindhoven, Helmond en tenslotte eindigt het pad bij Lectoraat Automotive Control. Als voorbeeld wordt het project Cooperative Driving getoond. Parallel aan de schets van werkzaamheden wordt besproken wat de veranderingen zijn in automotive onderwijs. Traditioneel komt automotive vanuit de invalshoek werktuigbouwkunde. De nieuwe opleidingen automotive HBO en WO zijn meer gericht op de drie componenten werktuigbouwkunde, elektrotechniek en ICT.

De auteurs "allen werkzaam bij TNO, hebben zich gebogen over inclusieve technologie. Dat is technologie die kwetsbare mensen ondersteunt in het zoeken naar werk en/of aan het werk blijven. Belangrijke factoren hierbij zijn zoekintentie, -vaardigheden, goede taakuitvoering, vitaliteit, ontwikkeling en mobiliteit."

De ‘last mile’ verhuist naar de voorhoede, waarmee het logistiek vastgoed steeds dichter bij de stedelijke ruimte komt. Maar waar in de stedelijke ruimte? Creativiteit is geboden.

Hyperloop scale-up Hardt and Amsterdam University of Applied Sciences explored how hyperloop cargo solutions (Cargoloop) can help sustainably and efficiently meet surging demand for e-commerce shipments. A new vision paper titled ‘Hyperloop for E-commerce – Sustainable, on-demand and high-speed e-commerce fulfillment enabled by Cargoloop’ was published, as a result of joined concept development and E-commerce industry consultation.It concludes that hyperloop technology has “game-changing” potential as governments, retailers, and thought leaders seek sustainable freight solutions.

A multilayer scheme is here proposed to implement coordinated control of a group of mobile robots. Specifically, a trajectory tracking controller is proposed to coordinately guide a platoon of robots, with an obstacle deviation subsystem based on virtual forces and mechanical impedance implemented in each robot. Such a controller is firstly designed for groups of three robots and then generalized to larger groups ($$n>3$$n>3 robots), by proposing a modular structure based on the concatenation of triangular modules, composing a polygon of $$n$$n sides (one of the designed controllers is adopted to guide each module). The stability of the closed-loop control system is also proven for each individual control system, based on the theory of Lyapunov, taking into account the saturation of the control signals, adopted to prevent the saturation of the robot actuators. Based on such a proof, a conjecture that the whole control system is stable is presented, which is supported by several simulated and experimental results, some of which are presented, thus validating the proposed control structure.

The purpose of this paper is to perform a metaphorical analysis of knowledge as energy. This paper is based on a theoretical research concerning the nature, perception, basic laws and challenges brought up by these fundamental concepts of knowledge and energy. The metaphorical analysis of knowledge and intellectual capital has been initiated by Daniel Andriessen and his findings have been presented in several seminal works (Andriessen, 2006; 2008; Andriessen and Boom, 2007). In his work, Andriessen concluded we need to find new metaphors for knowledge. In our theoretical research we shall consider the knowledge as energy metaphor, with energy as the source domain, and knowledge as the target domain, and we are interested in identifying the metaphorical semantic kernel and the limitations of this analysis. The semantic kernel contains: (1) the concept of field as a nonuniform and nonlinear distribution of knowledge; (2) dynamics of potential and kinetic forms of manifestations; (3) dynamics of work and heat, and (4) entropy and syntropy process characteristics. Limitations of this analysis come from the conservation laws of energy transformation which cannot be applied to the knowledge domain.
