Authors: Ozel Sahin Sahika , Arbag Huseyin , Oktar Nuray , Murtezaoglu Kirali 
Published: June 2019

Abstract
In this study, mesoporous alumina supported bi-metallic Ni-Co catalysts were synthesized and catalytic performances were investigated in hydrogen production through steam reforming of acetic acid reaction. Mesoporous alumina support was synthesized using a sol-gel method and metals were co-impregnated into the structure of the catalyst. The physicochemical properties of the synthesized materials were characterized by XRD, N2 adsorption-desorption, SEM and TG-DT analysis. The activity test results showed that the bi-metallic 4Ni-1Co@SGA catalyst showed high and stable activity in steam reforming of acetic acid, giving a high H2 selectivity at 750 °C. Bi-metallic Ni-Co catalysts showed higher performance than monometallic Co catalyst, yielding less methane production and coke deposition. Co incorporation decreased activity of Ni catalysts at high reaction temperature of 750 °C in terms of AcOH conversion; however, improved the activity of Ni catalysts at low reaction temperature of 550 °C in terms of AcOH conversion and H2 Selectivity. Mg incorporation enhanced the coke resistance of the catalyst and further, among the bi- and tri-metallic catalysts, the lowest coke deposition was obtained over Mg incorporated 4Ni-1Co@SGA catalyst at 750 °C.

Abstract
The feasibility of ohmic heating was tested for cooking instant home meal replacement (HMR) curry mixture. A curry mixture (curry powder, spam, carrot, potato, and water) was ohmically heated to 100 °C using different electric fields (9, 12, 15, and 18 V/cm). Temperature come-up time to 100 °C of curry soup were 5.27 ± 0.63, 3.15 ± 0.39, 2.28 ± 0.19, and 1.67 ± 0.24 min at the electric fields of 9, 12, 15, and 18 V/cm, respectively. The come-up time was decreased as a function of enhanced electric fields (P < 0.05). In terms of energy efficacy, the highest electric field (18 V/cm) resulted in the most efficient system performance coefficient (SPC), with a score of 0.62. In terms of textural qualities, cooking at 15 V/cm of carrot and potato the hardness was 3.41 ± 0.69 N and 1.04 ± 0.18 N, respectively, that resulted in the ideal level of hardness. Our study proposed the positive feasibility of ohmic heating to cook HMR curry soup.
Maschinelles Lernen und NLP: Reif für die industrielle Anwendung!
Authors: Geißler Stefan 
Published: June 2019

Zusammenfassung
Anwendungen von maschinellen Lernverfahren (ML) haben in jüngster Zeit aufsehenerregende Durchbrüche bei einer ganzen Reihe von Aufgaben in der maschinellen Sprachverarbeitung (NLP) erzielt. Der Fokus vieler Arbeiten liegt hierbei in der Entwicklung immer besserer Modelle, während der Anteil der Aufgaben in praktischen Projekten, der sich nicht mit Modellbildung, sondern mit Themen wie Datenbereitstellung sowie Evaluierung, Wartung und Deployment von Modellen beschäftigt, oftmals noch nicht ausreichend Beachtung erfährt. Im Ergebnis fehlen gerade Unternehmen, die nicht die Möglichkeit haben, eigene Plattformen für den Einsatz von ML und NLP zu entwerfen, oft geeignete Werkzeuge und Best Practices. Es ist zeichnet sich ab, dass in den kommenden Monaten eine gerade diesen praktischen Fragen zugewandte Ingenieurssicht auf ML und ihren Einsatz im Unternehmen an Bedeutung gewinnen wird.
Receptive multilingualism versus ELF: How well do Slovenes understand Croatian compared to Croatian speakers’ English?
Authors: Bulatović Stefan , Schüppert Anja , Gooskens Charlotte 
Published: June 2019

Abstract
This study investigates the degree of intelligibility of Croatian and Croatian speakers’ English for native Slovene listeners. For the purposes of the present experiment, 18 native speakers of Croatian were recorded narrating two short films in their mother tongue as well as in English. Each of the 135 participants, whose L1 is Slovene, listened to a recorded Croatian speaker retelling one story in their native language and another in English. The intelligibility of the two communicative modes was measured using multiple-choice questions. Overall, the level of comprehension was found to be higher for English than for Croatian. Two extralinguistic factors (border proximity and language preference) were also considered so as to gain a deeper insight into the nature of the intelligibility of English as a lingua franca (ELF) and receptive multilingualism as two potential mediums of communication between Croatian and Slovene speakers.
The Regularized Weak Functional Matching Pursuit for linear inverse problems
Authors: Kontak Max , Michel Volker 
Published: June 2019

Abstract
In this work, we present the so-called Regularized Weak Functional Matching Pursuit (RWFMP) algorithm, which is a weak greedy algorithm for linear ill-posed inverse problems.
In comparison to the Regularized Functional Matching Pursuit (RFMP), on which it is based, the RWFMP possesses an improved theoretical analysis including the guaranteed existence of the iterates, the convergence of the algorithm for inverse problems in infinite-dimensional Hilbert spaces, and a convergence rate, which is also valid for the particular case of the RFMP.
Another improvement is the cancellation of the previously required and difficult to verify semi-frame condition.
Furthermore, we provide an a-priori parameter choice rule for the RWFMP, which yields a convergent regularization.
Finally, we will give a numerical example, which shows that the “weak” approach is also beneficial from the computational point of view.
By applying an improved search strategy in the algorithm, which is motivated by the weak approach, we can save up to 90  of computation time in comparison to the RFMP, whereas the accuracy of the solution does not change as much.

Published: June 2019

AbstractDiabetic nephropathy (DN) is considered as one of the most popular microvascular complications of diabetes and the leading cause of death among diabetic patients. Currently, even though safflower yellow (SY) is widely adapted in the clinical treatment of DN, no meta-analysis can guarantee the safety of this treatment. This paper aims to evaluate the dominant method of SY on DN disease. The reliable source of information for randomized controlled trials (RCTs) and clinical research is listed as follows: the Chinese Biomedical Literature database, Chongqing VIP, Embase, the Cochrane Library and the China Academic Journals Full-text Database (CNKI). The CNKI search included Chinese journal articles, the full-text of important conferences and dissertations up to March 30, 2017. We picked out some particularly influential outcome variables including urinary albumin excretion rate (UAER), fasting blood sugar (FBG), blood urea nitrogen (BUN) and high-sensitivity C-reactive protein (hs-CRP) in each extracted study. In total, 1289 participants were included in this meta-analysis. The efficacy of SY alone or combined with Western medicine in the treatment of DN was better with statistically significant factors (odds ratio [OR] = 3.6, 95% confidence interval [CI] [2.37, 5.47], p < 0.00001). We found that SY lessened the UAER, heightened the proportion of blood sugar and beneficially improved other detective indicators related to DN. Therefore, SY used alone or in combination with Western medicine was significantly more efficacious with lower toxicity than Western medicine alone.
Die Aufrichtigkeit als die Wurzel der Moralität. Kant (und Nietzsche)
Authors: Sirovátka Jakub 
Published: June 2019

Abstract
In this essay, I examine the motive of inner truthfulness in the moral philosophy of Kant, which came to the fore in his work in the 1790s. Truthfulness and sincerity are interpreted as the roots of all morality. In the first chapter, I present two interpretations of inner honesty from two different perspectives: in relation to a duty to oneself and to the issue of conscience. The second chapter (the core of the essay) works out the main demand of truthfulness, especially in the context of the theory of radical evil from Religion within the Boundaries of Mere Reason. As a last step, I show that with the motive of truthfulness, Kant’s philosophy meets the thinking of F. Nietzsche, with its emphasis on sincerity.
Sentence-final aspect particles as finite markers in Mandarin Chinese
Authors: Zhang Niina Ning 
Published: June 2019

AbstractIn Mandarin Chinese, sentence-final aspect particlesne, le, andlaizhemay occur in some types of embedded clauses, but not in other types, such as the complement of a control verb, a raising verb,lai‘come’ andqu‘go’, a non-epistemic modal, and the prepositional complementizerdui‘to’. These latter types of clauses systematically show properties of nonfinite clauses in other languages. They are intrinsically embedded, banpro-drop, their clause boundaries may be invisible for binding, and they disallow a speaker-oriented adverb and an epistemic modal. The restrictions on the distribution of the particles indicate that they are used in finite clauses only, although the language has no tense or case marker. The paper argues that finite clauses show speaker-oriented properties whereas nonfinite ones do not; instead, nonfinite clauses exhibit higher-clause-oriented properties. Identifying the role of speaker in the finiteness distinction reveals the capacity of finite clauses, whether or not the capacity is marked overtly.

Abstract
Reaction of anhydrous tin(IV) chloride with mono functional bidentate Schiff bases (sbnH), in 1:2 molar ratios, gives complexes of the type, [(sbn)2SnCl2] (1-4) (where, n=1-4; sb=2-(((4-chlorophenyl)imino)methyl)phenol, sb1H, I; 2-(((4-bromophenyl)imino)methyl) phenol, sb2H, II; 2-(((4-chlorophenyl)imino)methyl)-6-methoxyphenol, sb3H, III and 2-(((4-bromo phenyl)imino)methyl)-6-methoxyphenol, sb4H, IV. All the tin(IV) complexes (1-4) were colored solid and soluble in organic solvents. The synthesized complexes were characterized by elemental analysis (C, H, N and Sn), IR, UV-Vis, NMR (1H, 13C and 119Sn) spectroscopy and mass spectrometry. On the basis of spectroscopic studies, six coordination around tin atom has been proposed tentatively. The computational calculations using density functional theory (DFT) of ligands and complexes were also performed to obtained optimized molecular geometry, the highest occupied molecular orbital (HOMO), the lowest unoccupied molecular orbital (LUMO) and other parameter.
Innovation Management in Good Practice Context
Authors: Fobel Pavel , Forgon Tomáš , Klimentová Fobelová Monika 
Published: June 2019

Abstract
The issue of innovation has also been pursued in social sciences and subsequently specifically in the field of application of socio-scientific knowledge. It is not just about professional engineering ethics but we perceive it in a complex and wider social context. Doing good as well as good practice are more than the professional code of ethics or an effort for technical or managerial excellence. Innovative changes should not be parameterized solely by economic efficiency or performance. With regard to new knowledge and technology development, their ethical aspects become more important and focus more on good life. In the context of social sciences with interdisciplinary trends, applied ethics and its subdisciplines (professional ethics, business ethics, ethics of science and research) can take over and play an important practical role. Innovative processes are increasingly becoming the focus of applied ethics, especially in terms of ethical risks. Our mission is to offer an interdisciplinary view of innovation as discussed in the ethics aspect. Based on these considerations, we conclude that ethics need to be integrated into individual innovation processes and adopted as an important condition for eliminating (mitigating) social risks. In our theoretical considerations we offer a view of the scientific risks and forms of prevention related to innovative change in important areas including engineering practice or health protection.

Published: June 2019

Abstract

Chamaepinnularia thermophila is a small and poorly known diatom species. After the first description from a hot spring in Guadalupe in 1952, its presence appeared to be limited to a few other springs of the French Antilles. The objective of this study is to report new information on aspects of taxonomy, distribution and ecology of this species. Accurate analysis under light and scanning electron microscope of the material collected on different substrates (cobbles, macrophytes and fine sediments) from a thermo-mineral spring of Sardinia (Italy) allowed us to document the first record of the species in the Mediterranean area. Furthermore, the comparison with Navicula tongatensis from Hustedt's original material, carried out because of their similarity, revealed identical morphological characteristics suggesting their consequent synonymy. Based on the information available in the literature and our data, C. thermophila is a rare species present mainly in tropical areas, in thermal springs with alkaline pH, medium to high conductivity and low to moderate nutrient content. The occurrence of the species at sites with very different environmental characteristics seems unusual, but it could indicate a broader ecological range. This study contributes to the standardization of the nomenclature used for this species so far and provides the first framework on its global geographic distribution and ecology.

Published: June 2019

Abstract
The family of Bacillariaceae Ehrenberg is a group of well-known raphid diatoms, associated with water quality. Our current knowledge of the species diversity of this group in Turkey is still incomplete. There are three river basins in the Kütahya region in Turkey, located in the eastern part of the country, including the Gediz, Sakarya and Susurluk basins, thus the region is rich in lotic waters. We present each taxon based on our observations of specimens collected in the Kütahya region. A total of 53 sites were surveyed in this study and a total of 65 taxa from Bacillariaceae were identified. Of these 65 taxa, 15 are recognized as the first records for Turkey. For each taxon, we indicate the reference(s) used for its identification. To facilitate the identification by others working on the Turkish freshwater diatom flora, we also present dimensions of the taxa identified, the distribution of each taxon in the Kütahya region, the distribution of each taxon in Turkey as well as one or more figures for each taxon.
Vibration analysis of functionally graded materials for cylinder liner used in agricultural engine part
Authors: Prakash Anand , Kumar Shiv Ranjan , Verma Rahul 
Published: June 2019

AbstractThe engine part is one of the major sources of vibration of agricultural machinery such as a tractor. Therefore, vibration analysis of agricultural engine part will improve the engine efficiency and agricultural performance. The main objective of present work was to study the dynamic behavior of functionally graded (FG) structural material for the application as cylinder liner as agricultural engine part. The vibration analysis of functionally graded (FG) beam was performed using Finite Element Method (FEM). A typical simply-supported FG beam was modeled in COMSOL Software, where the upper portion of the beam was alumina and the lower portion was steel. The basic properties of material such as Young’s Modulus and mass density were varied along the thickness according to the power law. The boundary conditions were also modeled, and parametric study was carried out with mass density and young’s modulus. Eigen value problem was solved and in turn natural frequency and mode shapes were obtained. The frequency ratio was calculated and compared for various boundary conditions. The finding of the results indicated that when power exponent was increased from 0 to 5, the nonlinear reduction in frequency was occurred but when power exponent was increased from 5 to 10, linear reduction in frequency was occurred. Also, the increase in power exponent caused the increase in frequency for Young’s Modulus ratio of 0.25 and 0.5, decrease in frequency for Young’s Modulus ratio of 2 and 4 and no change occurred for Young’s Modulus ratio of 1. The first non-dimensional frequency for Clamped-Clamped boundary condition was comparatively more than other boundary conditions and lowest frequency is obtained for Clamped –Free boundary conditions.
Wie dezentral sind Geldpolitik und Bankenaufsicht in Europa?
Authors: Steinkamp Sven 
Published: June 2019

Zusammenfassung
Entgegen der landläufigen Meinung betreibt die Europäische Währungsunion keine vollständig zentralisierte Geldpolitik, sondern ist föderalistisch strukturiert. Der Autor stellt die dezentralen Elemente europäischer Geldpolitik in einer institutionellen Analyse vor und erläutert Chancen und Risiken. Insbesondere bei der Beurteilung der Bankensolidität, der Schaffung notenbankfähiger Sicherheiten, der Notfall-Liquiditätshilfe sowie den Portfolioentscheidungen der nationalen Zentralbanken gibt es diskretionäre Entscheidungsspielräume. Diese helfen, asymmetrische Schocks zu dämpfen und Ansteckungseffekte einzudämmen. Sie sind seit der Eurokrise aber auch in die Kritik geraten, Anreizprobleme und Interessenkonflikte zu verursachen. Bei den Anleihekäufen finden sich Hinweise auf moralische Risiken: Nationale Zentralbanken handeln riskanter, wenn sie das Risiko ihrer Käufe innerhalb der Währungsunion teilen. Mittelfristig ließe sich dies ändern, die aktuellen Abstimmungsverfahren des Eurosystems erschweren Reformen jedoch.

Published: June 2019

AbstractTiO2 is the most promising oxide semiconductor extensively used as photocatalyst in solar energy conversion into hydrogen and electric energy as well as in degradation of contaminants in water. To increase its efficiency, carbon dopants are applied. A series of TiO2/graphitic carbon nanocomposites with enhanced photocatalytic performance was synthesized at different temperatures in the 300 – 850°C range in the presence of benzene vapours. To investigate the magnetic properties of these nanocomposites, the dc magnetic susceptibility and electron paramagnetic resonance (EPR) measurementswere carried out. Magnetometry revealed the presence of three very different components: a temperature independent and easily recognized in the high-temperature range, another one in 20 – 100 K range displaying a slow increase with temperature decrease and saturation at low temperatures, and the third one observed at T < 20 K showing a sharp increase with decreasing temperature. Five types of EPR spectra were detected in the investigated samples and attributed to various paramagnetic centres. The role of TiO2 phase composition, nanocrystalline sizes, carbon content in its different forms in establishing static and dynamic magnetic response of our samples will be discussed.
Optical inline inspection detecting 3D defects on complex free-form surfaces in harsh production environments
Authors: Strohmeier Michael , Schröder Matthias , Faber Christian 
Published: June 2019

Abstract
In today’s industrial manufacturing, quality monitoring is one of the key elements to ensure continuous improvement and to trigger innovations. Especially inline inspection presents considerable challenges to the underlying measurement system. Besides the – in most cases – already not easily satisfiable demands concerning resolution, measurement uncertainty, and cycle time, the robustness of the chosen solution within the overall production environment is an essential requirement for a successful operation in the field. Furthermore, a sufficient ease of operation for the production staff plays a crucial role for the acceptance of the measurement technology. In sheet metal forming, for example, vibrations, ambient light variations and short cycle times as well as oiling and surface variations of the specimen under test challenge and simultaneously limit currently available measurement systems in their application. Especially in automotive manufacturing, visionary design concepts increase the complexity of components with respect to shape and forming capability, leading to critical areas on the object prone to constrictions and cracks. Varying geometry and surface defect characteristics call for an automated 3D inspection to maintain constant product quality for each single part. In this paper, an applied method for the inline inspection of free-form metal surfaces is presented, which allows for quality monitoring even in a harsh environment. So-called inverse fringe projection in combination with single-sideband demodulation facilitates the inspection of free-form metal surfaces in 3D, based on a single camera image (‘single-shot’), which allows for measurement even in a vibrating environment. Only one single camera and a projector are needed, simplifying the integration into series production considerably. Calibration-free, fast setup possibilities enable flexible handling and maintenance in a short-cycled production. First inline tests in a press shop at BMW proof the capability of this method. As an example, constrictions with a depth of about 80 microns could be detected automatically during series production within the press.
