Vehicle2Grid is a new charging strategy that allows for charging and discharging of Plug-In Hybrid Electric Vehicles (PHEV) and Full Electric Vehicles (FEV). The discharged energy can be supplied back to the (local) energy grid, enabling for grid alleviation, but can also be supplied back to the household in the case of a Vehicle2Home connection. Vehicle2Grid is an innovative and complex systems that requires adequate input from users if the local energy grid is to fully benefit from the discharged energy. Users have to be willing for the State of Charge of their EV to be adjusted in order for the Vehicle2Grid system to actually discharge energy from the EV. However, limiting the potential range of an EV can act as a barrier for the use of a Vehicle2Grid system, as discharging might cause uncertainty and possible range anxiety. Charging and discharging an EV through the use of Vehicle2Grid is therefore expected to change user’s routines and interactions with the charging system. Yet few Vehicle2Grid studies have focused on the requirements of a Vehicle2Grid system from the perspective of the user. This paper discussed several incentives and design guidelines that focus on the interaction users have with a Vehicle2Grid system in order to optimize user engagement with the system and integrate user preferences into the complex charging strategy. Results were obtained through a brief literature study, from a focus group as well as from two Vehicle2Grid field pilots. At the end of the paper, recommendations for further research are given.
Promotor : Prof. dr. S. Brinkkemper In recent years the focus on business process improvement has greatly increased in industry as well as in public and health institutions. Information systems and especially Business Process Management (BPM) systems are essential to achieve this. Despite success and opportunities for organizations that innovate with BPM applications there are also many failures of implementations caused by both technical and non-technical problems. In many instances it appears that user participation and user involvement are critical to the success of implementation. To overcome the many problems this thesis reports on research that focused on the improvement of the user participation practice. Therefore the main research question in this PhD thesis is: How can user participation in BPM implementation be successful?
Technology can assist older adults to remain living in the community. Within the realm of information and communication technologies, smart homes are drifting toward the concept of ambient assisted living (AAL). AAL-systems are more responsive to user needs and patterns of living, fostering physical activity for a healthier lifestyle, and capturing behaviours for prevention and future assistance. This study provides an overview of the design-requirements and expectations towards AAL-technologies that are formulated by the end-users, their relatives and health care workers, with a primary focus on health care in The Netherlands. The results concern the motivation for use of technology, requirements to the design, implementation, privacy and ethics. More research is required in terms of the actual needs of older users without dementia and their carers, and on AAL in general as some of the work included concerns less sophisticated smart home technology
With the help of sensors that made data collection and processing possible, many products around us have become “smarter”. The situation that our car, refrigerator, or umbrella communicating with us and each other is no longer a future scenario; it is increasingly a shared reality. There are good examples of such connectedness such as lifestyle monitoring of elderly persons or waste management in a smart city. Yet, many other smart products are designed just for the sake of embedding a chip in something without thinking through what kind of value they add everyday life. In other words, the design of these systems have mainly been driven by technology until now and little studies have been carried out on how the design of such systems helps citizens to improve or maintain the quality of their individual and collective lives. The CREATE-IT research center creates new solutions and methodologies in “digital design” that contribute to the quality of life of citizens. Correspondingly, this proposal focuses on one type of digital design—smart products—and investigate the concept of empowerment in relation to the design of smart products. In particular, the proposal aims to develop a model with its supplementary tools and methods for designing such products better. By following a research-through-design methodology, the proposal intends to offer a critical understanding on designing smart products. Along with its theoretical contribution, the proposal will also aid the students of ICT and design, and professionals such as designers and engineers to create smart products that will empower people and the industry to develop products grounded in a clear user experience and business model.
Despite the benefits of the widespread deployment of diverse Internet-enabled devices such as IP cameras and smart home appliances - the so-called Internet of Things (IoT) has amplified the attack surface that is being leveraged by cyber criminals. While manufacturers and vendors keep deploying new products, infected devices can be counted in the millions and spreading at an alarming rate all over consumer and business networks. The objective of this project is twofold: (i) to explain the causes behind these infections and the inherent insecurity of the IoT paradigm by exploring innovative data analytics as applied to raw cyber security data; and (ii) to promote effective remediation mechanisms that mitigate the threat of the currently vulnerable and infected IoT devices. By performing large-scale passive and active measurements, this project will allow the characterization and attribution of compromise IoT devices. Understanding the type of devices that are getting compromised and the reasons behind the attacker’s intention is essential to design effective countermeasures. This project will build on the state of the art in information theoretic data mining (e.g., using the minimum description length and maximum entropy principles), statistical pattern mining, and interactive data exploration and analytics to create a casual model that allows explaining the attacker’s tactics and techniques. The project will research formal correlation methods rooted in stochastic data assemblies between IoT-relevant measurements and IoT malware binaries as captured by an IoT-specific honeypot to aid in the attribution and thus the remediation objective. Research outcomes of this project will benefit society in addressing important IoT security problems before manufacturers saturate the market with ostensibly useful and innovative gadgets that lack sufficient security features, thus being vulnerable to attacks and malware infestations, which can turn them into rogue agents. However, the insights gained will not be limited to the attacker behavior and attribution, but also to the remediation of the infected devices. Based on a casual model and output of the correlation analyses, this project will follow an innovative approach to understand the remediation impact of malware notifications by conducting a longitudinal quasi-experimental analysis. The quasi-experimental analyses will examine remediation rates of infected/vulnerable IoT devices in order to make better inferences about the impact of the characteristics of the notification and infected user’s reaction. The research will provide new perspectives, information, insights, and approaches to vulnerability and malware notifications that differ from the previous reliance on models calibrated with cross-sectional analysis. This project will enable more robust use of longitudinal estimates based on documented remediation change. Project results and methods will enhance the capacity of Internet intermediaries (e.g., ISPs and hosting providers) to better handle abuse/vulnerability reporting which in turn will serve as a preemptive countermeasure. The data and methods will allow to investigate the behavior of infected individuals and firms at a microscopic scale and reveal the causal relations among infections, human factor and remediation.
It is VHL’s mission to train high-quality, committed and innovative professionals who con-tribute to a more sustainable world , and who are able to organize and manage multi-stakeholder processes for sustainable change: graduates with transdisciplinary competences. Secondly, VHL aims to contribute to the SDG-agenda by linking its education and applied research to eight particular SDGs of which Resilient Communities is one. However, to operationalize SDGs in practice, and aligning targets and strategies of different stakeholders is difficult: ‘resilience’ and ‘sustainability’ refer to ‘wicked problems’ for which no definitive problem formulation, nor clear-cut solutions exist. Addressing wicked problems like ‘resilience’ and ‘sustainability’ requires transdisciplinary collaboration to manage and transform divergent values and conflicting interests, and to co-create sustainable innovations. This HBO postdoc views the 17 SDGs as a compass to align targets and strategies of citizens, government, civil society organizations, private sector and knowledge institutes who collaborate in Living Labs of VHL focusing on resilient communities/regions. Through spiraling action-reflection cycles, stakeholders will use the SDG compass to make success mechanisms, obstacles and trade-offs visible, assuming they stay engaged to overcome difficulties to improve interventions and innovations; this is expected to result in adapted sustainability practices and lessons learned on reaching community resilience. The postdoc’s aim is two-fold highlighting the link between research and education: (1) Design a methodology to integrate SDGs effectively in VHL’s applied research: using the SDGs as compass to improve performance and outcomes of transdisciplinary collaborations. (2) Develop a Roadmap for transdisciplinary education at course, curriculum, and institutional level with SDGs as compass. Future graduates require the competence to work together with others outside one own’s discipline, institute, culture or context. Living Labs offer a suitable learning environment to develop this competence
