From the article: This paper describes the external IT security analysis of an international corporate organization, containing a technical and a social perspective, resulting in a proposed repeatable approach and lessons learned for applying this approach. Part of the security analysis was the utilization of a social engineering experiment, as this could be used to discover employee related risks. This approach was based on multiple signals that indicated a low IT security awareness level among employees as well as the results of a preliminary technical analysis. To carry out the social engineering experiment, two techniques were used. The first technique was to send phishing emails to both the system administrators and other employees of the company. The second technique comprised the infiltration of the office itself to test the physical security, after which two probes were left behind. The social engineering experiment proved that general IT security awareness among employees was very low. The results allowed the research team to infiltrate the network and have the possibility to disable or hamper crucial processes. Social engineering experiments can play an important role in conducting security analyses, by showing security vulnerabilities and raising awareness within a company. Therefore, further research should focus on the standardization of social engineering experiments to be used in security analyses and further development of the approach itself. This paper provides a detailed description of the used methods and the reasoning behind them as a stepping stone for future research on this subject. van Liempd, D., Sjouw, A., Smakman, M., & Smit, K.

Standard mass-production is a well-known manufacturing concept. To make small quantities or even single items of a product according to user specifications at an affordable price, alternative agile production paradigms should be investigated and developed. The system presented in this paper is based on a grid of cheap reconfigurable production units, called equiplets. A grid of these equiplets is capable to produce a variety of different products in parallel at an affordable price. The underlying agent-based software for this system is responsible for the agile manufacturing. An important aspect of this type of manufacturing is the transport of the products along the available equiplets. This transport of the products from equiplet to equiplet is quite different from standard production. Every product can have its own unique path along the equiplets. In this paper several topologies are discussed and investigated. Also, the planning and scheduling in relation to the transport constraints is subject of this study. Some possibilities of realization are discussed and simulations are used to generate results with the focus on efficiency and usability for different topologies and layouts of the grid and its internal transport system.

Closely related with this problem is the scheduling of the production in the grid. A discussion about the maximum achievable load on the production grid and its relation with the transport system is also included.

Abstract: Last few years the hindrance, accidents, pollution and other negative side effects of construction projects and namely construction transport have become an issue particularly in urban areas across Europe such as in London, and in the Netherlands as well, including the cities of Utrecht, Rotterdam and Amsterdam. Municipalities have issued new legislation and stricter conditions for vehicles to be able to access cities and city centres in particular and accessibility of older and polluting vehicles. Considerate clients, public as well private, have started developing tender policies to encourage contractors to reduce the environmental impact of construction projects. Contractors and third party logistics providers have started applying consolidation centres. These developments have shown considerable reductions of number of vehicles needed to deliver goods and to transport workers to site. In addition these developments have led to increased transport efficiency, labour productivity and cost reductions on site as well as down the supply chain. Besides these developments have led to increased innovations in the field of logistics planning software, use of ICT , and handling hardware and equipment. This paper gives an overview of current developments and applications in the field of construction logistics in the Netherlands, and in a few project cases in particular. Those cases are underway as part of an ongoing applied research project and studied by using an ethnographic participative action research approach. The case findings and project results show initial advantages how the projects, the firms involved and the environment can profit from the advancement of logistics management leading to reduced environmental impact and increased efficiencies of construction transport.

The Interreg Europe eBussed project supports the transition of European regions towards low carbon mobility and more efficient transport. The regions involved are Turku (Finland), Hamburg (Germany), Utrecht (The Netherlands), Livorno (Italy), South Transdanubia (Hungary) and Gozo island in Malta. It promotes the uptake of e-busses in new regions and supports the expansion of existing e-fleets. Within the project, there are four thematic working groups formed that aim at delivering a best practices report and policy recommendations to be used in the partner regions. Thematic Working Group 4 (TWG4) focusses on the topics of Procurement, Tendering and Costs of e-busses. As a starting point for TWG4, the value chain for e-bus public transport per region has been mapped. By mapping how the value chain for e-bus public transport works and defining the nature of the issues, problems or maybe challenges per region can be better understood.

In the current discourses on sustainable development, one can discern two main intellectual cultures: an analytic one focusing on measuring problems and prioritizing measures, (Life Cycle Analysis (LCA), Mass Flow Analysis (MFA), etc.) and; a policy/management one, focusing on long term change, change incentives, and stakeholder management (Transitions/niches, Environmental economy, Cleaner production). These cultures do not often interact and interactions are often negative. However, both cultures are required to work towards sustainability solutions: problems should be thoroughly identified and quantified, options for large change should be guideposts for action, and incentives should be created, stakeholders should be enabled to participate and their values and interests should be included in the change process. The paper deals especially with engineering education. Successful technological change processes should be supported by engineers who have acquired strategic competences. An important barrier towards training academics with these competences is the strong disciplinarism of higher education. Raising engineering students in strong disciplinary paradigms is probably responsible for their diminishing public engagement over the course of their studies. Strategic competences are crucial to keep students engaged and train them to implement long term sustainable solutions.

The importance of teaching engineering students innovation development is commonly clearly understood. It is essential to achieve products which are attractive and profitable in the market. To achieve this, an institute of engineering education has to provide students with needed knowledge, skills and attitudes including both technical and business orientation. This is important especially for SME’s. Traditionally, education of engineering provides students with basic understanding how to solve common technical problems. However companies need wider view to achieve new products. Universities of applied Sciences in Oulu and Eindhoven want to research what is the today’s educational situation for this aim, to find criteria to improve the content of the educational system, and to improve the educational system. Important stakeholders are teachers and students within the institute but also key-persons in companies. The research is realized by questionnaires and interviews from which a current situation can be found. The research will also include the opinion of management who give possibilities to change the curriculum. By this research more insight will be presented about how to re-design a current curriculum. The research will act as basis for this discussion in SEFI-conference about formulating a curriculum that includes elements for wide-ranging knowledge and skills to achieve innovations especially in SME’s.

The volume of biogas produced in agricultural areas is expected to increase in coming years. An increasing number of local and regional initiatives show a growing interest in decentralized energy production, wherein biogas can play a role. Biogas transport from production sites to user, i.e. a CHP, boiler or an upgrading installation, induces a scale advantage and an efficiency increase. Therefore the exploration of the costs and energy use of biogas transport using a dedicated infrastructure is needed. A model was developed to describe a regional biogas grid that is used to collect biogas from several digesters and deliver it to a central point. The model minimizes transport costs per volumetric unit of biogas in a region. Results are presented for different digester scales, different sizes of the biomass source area and two types of grid lay-out: a star lay-out and a fishbone lay-out. The model shows that transport costs in a fishbone lay-out are less than 10 Vct m3 for a digester scale of 100 m3 h1; for the star lay-outcosts can go up to 45 Vct m3. For 1800 m3 h1 digesters, these values are 4.0 Vct m3 and 6.1 Vct m3, respectively. The results indicate that cooperation between biogas producers in collecting biogas by means of a fishbone lay-out reduces the biogas transport costs relative to using a star lay-out. Merging smaller digesters into a smaller number of larger ones reduces the costs of biogas transport for the same biomass source area.

We found out that 25 % of our students came to study at the Electrical & Electronic Engineering department (E&E) because they were active (as a hobby) in music. Because of this the E&E department offers their students to work in video and audio themes in all projects of their education. From our inquiries we found out what students interests are and we use these interests for new project themes. The study has been changed in such a way that it is possible to have these project themes twice in every semester. Amongst them are, besides music, e.g. medical, sports, automotive and mechatronics. Other inquiries show that 47 % of our students choose for ICT because they are interested in computers or programming or do this for their hobby. Inspired by this the ICT department defined four new fields of interest: game design, management & security, mobile computing and life style. Both E&E and ICT connect the projects in their courses directly to industry and in this way students and lecturers are intensively involved in industry. From two surveys we learned that working this way is an excellent way to get students motivated and gives them drive and enjoyment in their study.

Abstract: Climate change is related with weather extremes, which may cause damages to infrastructure used by freight transport services. Heavy rainfall may lead to flooding and damage to railway lines, roads and inland waterways. Extreme drought may lead to extremely low water levels, which prevent safe navigation by inland barges. Wet and dry periods may alternate, leaving little time to repair damages. In some Western and Middle-European countries, barges have a large share in freight transport. If a main waterway is out of service, then alternatives are called for. Volume- and price-wise, trucking is not a viable alternative. Could railways be that alternative? The paper was written after the unusually long dry summer period in Europe in 2022. It deals with the question: If the Rhine, a major European waterway becomes locally inaccessible, could railways (temporarily) play a larger role in freight transport? It is a continuation of our earlier research. It contains a case study, the data of which was fed into a simulation model. The model deals with technical details like service specification route length, energy consumption and emissions. The study points to interesting rail services to keep Europe’s freight on the move. Their realization may be complex especially in terms of logistics and infrastructure, but is there an alternative?
