Wavelength Division Multiplexed based Passive Optical Networks (WDM-PON) are subjected to wide variety of incidental failures. It is preferred in WDM-PONs to provide fault management (survivability) at link layer level. In this paper, our objective is to determine the factors, which can increase the scope of survivability at link layer, not available currently. We propose a cost-effective recovery mechanism, called "Survivable Passive Access Network" (SPAN). SPAN is a multi-level protection scheme that has potential to be highly efficient and scaleable in terms of performance budget. BER performance and power penalty factors remain acceptable while switching traffic from normal path to protection path in case of failure. [less ▲]

Background: Deep brain stimulation (DBS) trajectory plan- ning is mostly based on standard 3-D T1-weighted gado- linium-enhanced MRI sequences (T1-Gd). Susceptibility- weighted MRI sequences (SWI) show neurovascular struc- tures without the use of contrast agents. The aim of this study was to investigate whether SWI might be useful in DBS trajectory planning. Methods: We performed bilateral DBS planning using conventional T1-Gd images of 10 patients with different kinds of movement disorders. Afterwards, we matched SWI sequences and compared the visibility of vas- cular structures in both imaging modalities. Results: By ana- lyzing 100 possible trajectories, we found a potential vascu- lar conflict in 13 trajectories based on T1-Gd in contrast to 53 in SWI. Remarkably, all vessels visible in T1-Gd were also de- picted in SWI, whereas SWI showed many additional vascular structures which could not be identified in T1-Gd. Conclu- sion/Discussion: The sensitivity for detecting neurovascular structures for DBS planning seems to be significantly higher in SWI. As SWI does not require a contrast agent, we suggest that SWI may be a valuable alternative to T1-Gd MRI for DBS trajectory planning. Furthermore, the data analysis suggests that vascular interactions of DBS trajectories might be more frequent than expected from the very low incidence of symptomatic bleedings. The explanation for this is currently the subject of debate and merits further studies. [less ▲]

Increasingly, engineers need to approach security and software engineering in a unified way. This paper presents an approach to the formal analysis of security requirements that is based on planning and uses the concept of suspicion to guide the search for threats and security vulnerabilities in requirements. The approach is tested and illustrated by conducting two experiments: one focussing on a system with a confidentiality security property, and another with an integrity security property enforced through the separation of duty principle. The paper shows that suspicion plays an important role in finding vulnerabilities and security threats in requirements. [less ▲]

The transition from today’s electricity grid to the so-called smart grid relies heavily on the usage of modern information and communication technology to enable advanced features like two-way communication, an automated control of devices, and automated meter reading. The digital backbone of the smart grid opens the door for advanced collecting, monitoring, and processing of customers’ energy consumption data. One promising approach is the automatic detection of suspicious consumption values, e.g., due to physically or digitally manipulated data or damaged devices. However, detecting suspicious values in the amount of meter data is challenging, especially because electric consumption heavily depends on the context. For instance, a customers energy consumption profile may change during vacation or weekends compared to normal working days. In this paper we present an advanced software monitoring and alerting system for suspicious consumption value detection based on live machine learning techniques. Our proposed system continuously learns context-dependent consumption profiles of customers, e.g., daily, weekly, and monthly profiles, classifies them and selects the most appropriate one according to the context, like date and weather. By learning not just one but several profiles per customer and in addition taking context parameters into account, our approach can minimize false alerts (low false positive rate). We evaluate our approach in terms of performance (live detection) and accuracy based on a data set from our partner, Creos Luxembourg S.A., the electricity grid operator in Luxembourg. [less ▲]

In our science-based society, we are surrounded by indicators. At every turn they tell us where we are, how we compare, where we should or should not be and whether we are moving towards or away from the desired or undesired state. Wealth and health of individuals, communities and natural systems are conveyed by indicators. Their representations include numbers, graphs, dials, letters, symbols and colours. And they vary in reliability, from the gauge that says your car’s engine temperature is ‘normal’, to the prediction that next month’s weather temperatures will be ‘normal’. They are one of the main channels whereby the citizen interacts with science. How can the citizen make good decisions in the midst of this jungle of indicators? The citizen might well ask, “What do I really know, when I’m told that I have an Ecological Footprint of 4.1 global hectares? And then what should I do about it?” [less ▲]

Listed firms increasingly strive for a sustainable appearance, which has made sustainability reporting very popular in recent years. This would be completely rational if sustainability reporting could enhance shareholder value. This paper investigates from a theoretical perspective which conditions are sufficient for the individual and collective rationality of sustainability reporting. The Analysis leads to the conclusion that, due to the competition between firms, sustainability reporting generates a separation equilibrium as long as the reporting costs are proportional to the reported level and the marginal costs of reporting differ with the true level of sustainability. Although it might be preferable, a pooling equilibrium with no sustainability reporting cannot be sustained, which is a result of the so-called prisoner’s dilemma that firms find themselves caught within. The most important practical implication of the model is a call for external auditing with high assurance levels to ensure an efficient separation of highly and weakly sustainable firms [less ▲]

Based on experiences from the GreenRegio research project that investigates framework conditions for innovations in sustainable/green building, this working paper explores the potential of interactive and collaborative methods for knowledge generation and co-production. Engagement with local practi-tioners, private industry, academics, political decision-makers and representatives of the non-profit sector early on in the research process allows researchers to gain better understanding of the re-search object and context. It also creates a platform for (mutual) knowledge exchange. Methodologi-cally, the project incorporates interactive workshops and Delphi-based feedback and validation rounds, that – over the lifespan of the project – offer a mutual learning process further inspired by in-sights and experiences across four case studies in Europe, Australia, and Canada. The exchange and learning processes provide important insights on different forms and pathways of sustainability transi-tions in the building sector to all participants involved in the project, researchers and researched alike.
