Report of the Special Rapporteur on the Issue of Human Rights Obligations Relating to the Enjoyment of a Safe, Clean, Healthy and Sustainable Environment: Framework Principles
Year: 2018

The final report of the Special Rapporteur on human rights and the environment calls on the United Nations to recognize the human right to a safe, clean, healthy and sustainable environment. The report also presents sixteen Framework Principles on Human Rights and the Environment, which summarize the human rights obligations of States in relation to the environment. The Principles describe: procedural obligations, including to provide environmental information, facilitate public participation in environmental decision making, and to provide for access to remedies for environmental harm; substantive obligations to adopt and implement standards that protect the enjoyment of human rights from environmental harm; obligations of international cooperation to address transboundary and global environmental harm; and obligations not to discriminate against, and to take additional measures to protect, those who are particularly at risk.
Insight into the potentiality of big biochar particle as an amendment in aerobic composting of sewage sludge.
Venue: Bioresource technology
Year: 2019

To assess the potential of big biochar as composting amendment, the study was performed on aerobic composting of sewage sludge amended with litchi wood biochar (10% of fresh mixture weight, 20 40 mm) in a 400 L bioreactor system. Physicochemical properties and microbial activities were monitored during the first fermentation process of aerobic compost. Application of big biochar reduced peak temperature and shortened thermophilic phase, but increased the activities of aryl sulfatase, b glucosidase, and dehydrogenase, which led to higher removal efficiency of total carbon, nitrogen, and sulphur. Big biochar inhibited degradation of organic matters in composting. Therefore, a comprehensive assessment including physicochemical and microbial properties can help to better understand the effect of big biochar on sewage sludge composting.
Rescuing Auditory Temporal Processing with a Novel Augmented Acoustic Environment in an Animal Model of Congenital Hearing Loss
Venue: eNeuro
Year: 2021

Congenital sensorineural hearing loss (SNHL) affects thousands of infants each year and results in significant delays in speech and language development. Previous studies have shown that early exposure to a simple augmented acoustic environment (AAE) can limit the effects of progressive SNHL on hearing sensitivity. However, SNHL is also accompanied by hearing loss that is not assessed on standard audiological examinations, such as reduced temporal processing acuity. To assess whether sound therapy may improve these deficits, a mouse model of congenital SNHL was exposed to simple or temporally complex AAE. The DBA/2J mouse strain develops rapid, base to apex, progressive SNHL beginning at birth and is functionally deaf by six months of age. Hearing sensitivity and auditory brainstem function was measured using otoacoustic emissions, auditory brainstem response (ABR) and extracellular recording from the inferior colliculus (IC) in mice following exposure to 30 d of continuous AAE. Peripheral function and sound sensitivity in auditory midbrain neurons improved following exposure to both types of AAE. However, exposure to a novel, temporally complex AAE more strongly improved a measure of temporal processing acuity, neural gap in noise detection in the auditory midbrain. These experiments suggest that targeted sound therapy may be harnessed to improve hearing outcomes for children suffering from congenital SNHL.
Poster: Towards Measuring Warning Readability
Year: 2012

Designing and writing warning messages can be considered a form of art that is often supported by engineering guidelines. A sizeable amount of research has evaluated different strategies to create effective warnings in the physical as well as the digital world [7, 5, 6] It has been recognised that the descriptive text provided in warning messages needs to be comprehensive and understandable by most computer users. In 2011, Bravo Lillo et al.  compiled a set of design guidelines and present the following rules for descriptive text: "describe the risk; describe consequences of not complying; provide instructions on how to avoid the risk; be brief; avoid technical jargon" Judging whether or not these goals are sufficiently met is however usually left to an expert's opinion or to testing through user studies. Consequently, there is considerable effort and knowledge involved in analysing and optimising warning messages. For over 60 years, educational research has developed and studied automatic measures to analyse text readability and suitability. Formulas, such as the Flesch Reading Ease, the Gunning Fog Index or the New Dale Chall Formula compiled from empirical analyses, allow a rough estimation of the number of years of education a reader has to have had in order to be able to comprehend a given text to a certain degree. The ongoing work presented in this poster examines the possibility of using automatic readability measures to support the analysis and creation of end user warning messages in computer software. We will present an initial analysis of browser security warnings using existing measures as well as a first explorative study of 15 students to analyse the applicability of these measures. To the best of our knowledge, there has not been any work investigating the application of readability measures for computer warning messages to date.
SOFC stacks for mobile applications with excellent robustness towards thermal stresses
Year: 2020

Solid oxide fuel cells (SOFC) are attractive power units for mobile applications, like auxiliary power units or range extenders, due to high electrical efficiencies, avoidance of noble metals, fuel flexibility ranging from hydrogen to hydrogen carriers such as ammonia, methanol or e gas, and tolerance towards CO and other fuel impurities. Among challenges hindering more wide spread use are the robustness under thermal cycling. The current study employs short stacks containing anode or metal supported SOFCs, which were subjected to thermal cycles in a furnace and under more realistic conditions without external furnace. Heating from 100 degC to operating temperature was accomplished by sending hot air through the cathode compartment and heating from bottom (and top) of the stack, reaching a fastest ramping time of ca. 1 h. The stacks remained intact under severe temperature gradients of at least 20 degC/cm for anode supported and 30 degC/cm for metal supported SOFCs.
Efficacy of n Heptane as a Xylene Substitute in Routine Histo pathology
Year: 2019

The aim of our study was to evaluate the efficacy of n Heptane (C7H16) as a xylene substitute for clearing, deparaffinizing and staining procedures in routine histopathology. 30 biopsied oral tissues were divided in two halves, each half was processed by xylene and n Heptane respectively.  To substitute toxic aromatic solvents with nonhazardous aliphatic derivatives. The second part of the study was conducted with the objective to reduce the concentration of comparatively expensive n Heptane.  A sample size of 20 was considered for immunohistochemistry (IHC) with Cytokeratin and Vimentin as epithelial and connective tissue markers respectively.  Kappa statistical analysis established agreement between observers in all criteria's with significant p value 0.05. The p value 0.05) was not statistically significant with Mann Whitney U Test, for all criteria's indicating comparable results between n Heptane and xylene. The clarity, uniformity, crispness, section quality as well as cellular parameters of nuclear cytoplasmic staining, nuclear cytoplasmic contrast, cell morphology were found comparable between n Heptane and xylene.  n Heptane is not as hazardous and toxic as aromatic or chlorinated solvents. Thus it can be considered as a convenient substitute to xylene.

Attackers are not Stealthy: Statistical Analysis of the Well Known and Infamous KDD Network Security Dataset
Venue: 2020 4th Conference on Cloud and Internet of Things (CIoT)
Year: 2020

Anomaly based approaches for detecting network intrusions suffer from accurate evaluation, comparison, and deployment due to the scarcity of adequate datasets. Consequently, researchers resort to suboptimal datasets that no longer relate to a real world network nor provide insights for current network issues, such as the DARPA'98 dataset and its variants KDD'99 and NSL KDD. In this article, we propose a statistical study over the NSL KDD features, and we conclude that NSL KDD and the old KDD'99 should not be used as a benchmark for creating novel anomaly based approaches intrusion detection systems because they introduce a biased classification, since features are over correlated. The proposed approach analyzes the correlation among features instead of checking for redundant values or the imbalance of data. Our results align with the performance of three machine learning techniques trained to discriminate attack from normal traffic. We show that biased classification occurs because there was a high correlation between features and classes. The syntactically generated features are statistically different between normal and attack traffic classes, which implies that, in KDD related datasets, attackers are not stealthy.
Composition dependent photocarrier dynamics in CH 3 NH 3 Pb(I 1 x Br x 3 thin films
Year: 2016

Over the past few years, organo metal halide perovskites have emerged as high potential materials for cost effective solar cell applications due to their excellent optoelectronic characteristics  The power conversion efficiency (PCE) of single junction perovskite solar cells increased incredibly, reaching over 20% at present  Besides current extensive efforts to improve further the PCE of single junction solar cells, using a perovskite subcell in a tandem structure as a top cell is a promising approach to realize devices with a much higher PCE [3] For such tandem solar cell applications, the band gap energy of and the recombination of photogenerated carriers in the perovskite layer take critical roles in determining the entire photovoltaic operation of a tandem device. The band gap energy of perovskite materials could be tuned flexibly and controllably through adjusting the contents of the halide elements  On the other hand, although tremendous studies examining the dynamical optical behaviors of photocarriers in pure halide perovskites have been done  understanding of the composition dependent photocarrier recombination dynamics in mixed halide perovskites has remained limited. In this work, we investigate the composition dependence of photocarrier recombination dynamics in CH3NH3Pb(I1 xBrx)3 (MAPb(I,Br)3) perovskite thin films by means of time resolved photoluminescence (PL) and transient absorption (TA) spectroscopy. The PL decay dynamics measured under weak excitation condition reveal an increase in the single carrier trapping rate with increasing the Br content in MAPb(I,Br)3 thin films. Using the obtained single carrier trapping rate, we are then able to evaluate the composition dependences of the two carrier recombination and Auger recombination rates from the excitation dependent TA kinetic traces. We discuss the physical issues behind the composition dependent photocarrier recombination dynamics in MAPb(I,Br)3 and its possible influences on the performance of perovskite solar cells.

Active terahertz metamaterial devices
Venue: Nature
Year: 2006

The development of artificially structured electromagnetic materials, termed metamaterials, has led to the realization of phenomena that cannot be obtained with natural materials. This is especially important for the technologically relevant terahertz (1 THz 1012 Hz) frequency regime; many materials inherently do not respond to THz radiation, and the tools that are necessary to construct devices operating within this range sources, lenses, switches, modulators and detectors largely do not exist. Considerable efforts are underway to fill this 'THz gap' in view of the useful potential applications of THz radiation. Moderate progress has been made in THz generation and detection; THz quantum cascade lasers are a recent example. However, techniques to control and manipulate THz waves are lagging behind. Here we demonstrate an active metamaterial device capable of efficient real time control and manipulation of THz radiation. The device consists of an array of gold electric resonator elements (the metamaterial) fabricated on a semiconductor substrate. The metamaterial array and substrate together effectively form a Schottky diode, which enables modulation of THz transmission by 50 per cent, an order of magnitude improvement over existing devices.

Diagnostics for Regression Models with Discrete Outcomes Using Surrogate Empirical Residual Distribution Functions
Year: 2019

Making informed decisions about model adequacy has been an outstanding issue for regression models with discrete outcomes. Standard residuals for such outcomes show a large discrepancy from the hypothesized pattern even under the true model and are often not informative especially when data are highly discrete. To fill this gap, we propose a surrogate empirical residual distribution function for general discrete (e.g. ordinal and count) outcomes that serves as an alternative to the empirical Cox Snell residual distribution function. The diagnostic tool we propose is a principled approach and does not require injecting noise to the data. When at least one continuous covariate is available, we show asymptotically that the proposed function converges uniformly to the identity function under the correctly specified model, even with highly discrete (e.g. binary) outcomes. Through simulation studies, we demonstrate empirically that the proposed surrogate empirical residual distribution function outperforms other commonly used residuals for various diagnostic tasks, since it is close to the hypothesized pattern under the true model and significantly departs from this pattern with model misspecification, and is thus an effective diagnostic tool.
Grundlagen der ganzheitlichen Fabrikplanung
Year: 2008

Die Festlegung von Inhalt, Umfang und Organisation der Fabrikplanung ist in der Praxis immer wieder ein Problem. Und nichts ist falscher als die falsche Aufgabenstellung oder falsche Vorgehensweise. Deshalb wird im zweiten Kaptitel das Verstandnis fur die Planungsheuristik in der ganzheitlichen Fabrikplanung aufgebaut. Die ,Ganzheitlichkeit" bezeichnet die Planungsbreite und tiefe, aber auch die Berucksichtigung aller Subsysteme und deren Wechselwirkungen. Die Prozessorientierung im Kontext der Fabrikplanung betrifft die Planungsprozesse, mit den Teilprozessen zur Gestaltung der Fabrik. Aber auch die Betriebsprozesse, mit den Teilprozessen des Fabrikbetriebs bzw. den Ergebnissen der Planungsprozesse. Die Organisationshierarchie eines ,Ganzheitlichen Produktionssystems (GPS)" womit sich heute fast alle Unternehmen, ob klein oder gros, befassen, bietet eine gute Struktur zur Einordnung der wesentlichen Komponenten der Fabrikplanung. Neu aufgenommen sind u.a. verschiedene Darstellungsformen der Planungssystematik und das Methoden Managementsystem zur Planungsunterstutzung.
Globalization and Individual Gains from Trade (revised version)
Year: 2012

We analyze the impact of globalization on individual gains from trade in a general equilibrium model of monopolistic competition featuring product diversity, pro competitive effects and income heterogeneity between and within countries. We show that, although trade reduces markups in both countries, its impact on variety depends on their relative position in the world income distribution: product diversity in the lower income country always expands, while that in the higher income country may shrink. When the latter occurs, the richer consumers in the higher income country may lose from trade because the relative importance of variety versus quantity increases with income. Using data on GDP per capita and population, as well as on the U.S. income distribution, we illustrate our theoretical results in two different contexts: the hypothetical bilateral trade liberalization between the U.S. and 188 countries; and the historical sequence of U.S. free trade agreements since 1985.
Combining ElasticFusion with PSPNet for RGB D Based Indoor Semantic Mapping
Venue: 2018 Chinese Automation Congress (CAC)
Year: 2018

Semantic segmentation has been a research focus of scene parsing and robotic manipulation. And increasing efforts are being made to empower geometry solely robotic mapping with semantic sensing ability in complex spatial cognition tasks, the so called semantic mapping. However, semantic mapping has not yet fully exploited the state of the art of semantic segmentation and suffered limitations of application scenario, number of object category and accuracy of object detection. Towards a robust semantic mapping solution, we propose a RGB D based fusion method that combines an improved ElasticFusion with PSPNet. PSPNet has the potential for breaking restrictions of limited object category in semantic segmentation of RGB images. As for map rendering, the improved ElasticFusion algorithm is validated for its robust performance in indoor scenes in terms of overall model accuracy and integral object shape geometry. Based on the two aforementioned modules, we fuses the semantic images and the depth images to generate 3D point cloud with semantic information. Experiments on the ICL NUIM datasets have proven the feasibility of the proposed method.
