In this paper, we discuss the application of speech dereverberation techniques for post-processing of recordings taken in the German parliament. Based on a novel psychoacoustically-motivated dereverberation concept, a significant improvement in terms of the perceived quality is obtained in comparison to a conventional dereverberation approach. Since time-varying changes of the acoustical enviro...

Climate-related hazards, more specifically droughts, floods and storms, cause the largest share of people affected by disasters major economic losses. While social disaster-related losses are monitored documented, this is not well established for environmental It known that degradation a key driver disaster risk. As such, healthy ecosystems acknowledged to contribute risk reduction (DRR) throug...

We introduce generalizations of stochastic network interdiction problem with distributional ambiguity. Specifically, we consider a distributionally risk-averse (or robust) (DRA-NIP) and risk-receptive (DRR-NIP) where leader maximizes follower's minimal expected objective value for either the worst-case or best-case, respectively, probability distribution belonging to ambiguity set (a distributi...

Abstract Nature-based solutions (NbS) are increasingly recognized as sustainable approaches to address societal challenges. Disaster risk reduction (DRR) has benefited by moving away from purely ‘grey’ infrastructure measures towards NbS. However, this shift also furthers an increasing trend of reliance on public acceptance plan, implement and manage DRR measures. In review, we examine how uniq...

This article highlights three key areas in which efforts to reduce the underlying causes of vulnerability and drivers of risk to environmental hazards need to be improved in order to create more inclusive, equitable and sustainable development: 1) the role of context and culture in creating risk, 2) the need to better link disaster risk reduction (DRR), climate change adaptation (adaptation) an...

Brachial as well as lumbosacral plexus avulsion injuries are usually caused by high kinetic traumas, such as car-pedestrian, car and motorcycle accidents or falls from great heights. Traction forces affecting the head and shoulders or extremities pull the spinal nerve sleeves away from the spinal cord and rupture the postganglionic spinal root from the cord. In so called central avulsion injuri...

The purpose of the paper is to present and evaluate the performance of a new software-based registration system for patient setup verification, during radiotherapy, using electronic portal images. The estimation of setup errors, using the proposed system, can be accomplished by means of two alternate registration methods. (a) The portal image of the current fraction of the treatment is register...

This study is conducted to analyze the performance of unicast networks by evaluating different queuing protocols under different criteria using multimedia data. That was achieved by using the NS-2 tool. The data traffic used in the simulation was CBR over UDP traffic because it is representative of multimedia data in the NS-2. Protocols tested in the simulation were FIFO, FQ, RED, DRR and SFQ. ...
