Internationalisierung der Fabrikplanung
Year: 2008

Kurzfassung Tief greifende Wandlungsprozesse in der industriellen Produktion und im Dienstleistungsbereich implizieren auch einen Wandel in der Fabrikplanung. Die Leistungstiefe von Fabrikplanung erweitert sich stetig und umfasst zunehmend Aufgaben, die uber die konventionellen Schritte einer traditionellen Fabrikplanung hinausgehen und Funktionen des Fabrikbetriebs sowie Um und Nachnutzungskonzepte enthalten. Ein bisher projektorientierter Fokus weicht einer netzwerkfokussierten, kontinuierlich lebenszyklusorientierten und internationalen Fabrikplanung. Eine Bereitstellung der gesamten Dienstleistungen des Fabriklebenszyklusses ist zwar im nationalen Rahmen vorzufinden, eine internationale kooperative Marktbearbeitung wird in diesem Rahmen jedoch selten ausgefuhrt. Auf Grund der Vielzahl der industriellen Dienstleistungen innerhalb des Fabriklebenszyklusses ist eine Untersuchung des Internationalisierungspotenzials dieser Dienstleistungen notwendig.
Classification of massive noisy image using auto encoders and convolutional neural network
Venue: 2017 8th International Conference on Information Technology (ICIT)
Year: 2017

Image processing tasks has found a new dimension with the improvement of learning feature representation from images using deep networks. Most of the research works are conducted over pre possessed image data in the lab. But, these methods fail in the real world scenario as most of the time the image required to classify is subject to noise and other disfigurement. For the last three decades, many researches has been conducted and numerus algorithms have been proposed with varying performances to classify noisy images. But in recent times, various autoencoders have outperformed all traditional methods for reconstructing native image from it's noisy form and opened a new door for the research of noisy image classification. In this paper, we studied various auto encoders for reconstructing native images from noisy input images. We have applied convolutional neural network as classifier. Before classification task we have rectified noisy images using denoising autoencoder, convolutional denoising autoencoder and finally a hybrid of them as proposed in this paper. The proposed methods are evaluated by experimenting over benchmark dataset adulterated with noises of different proportionate. This method has outperformed some other prominent methods achieving satisfying classification accuracy even when the image is too much noisy (50% noise is added with the image data)
Preparation of nickel iron hydroxides by microorganism corrosion for efficient oxygen evolution
Venue: Nature communications
Year: 2020

Nickel iron composites are efficient in catalyzing oxygen evolution. Here, we develop a microorganism corrosion approach to construct nickel iron hydroxides. The anaerobic sulfate reducing bacteria, using sulfate as the electron acceptor, play a significant role in the formation of iron sulfide decorated nickel iron hydroxides, which exhibit excellent electrocatalytic performance for oxygen evolution. Experimental and theoretical investigations suggest that the synergistic effect between oxyhydroxides and sulfide species accounts for the high activity. This microorganism corrosion strategy not only provides efficient candidate electrocatalysts but also bridges traditional corrosion engineering and emerging electrochemical energy technologies.
Gender Socialization during Adolescence in Low and Middle Income Countries Conceptualization, influences and outcomes
Year: 2017

The rapid changes that take place during adolescence provide opportunities for the development and implementation of policies and programmes, which can influence the gender socialization process, in order to maximize positive outcomes. This paper sets out to provide a conceptual understanding of the gender socialization process during adolescence, its influences and outcomes, and practical suggestions on how to use this knowledge in the design of policies and programmes to improve gender equality. First, theoretical contributions from psychology, sociology and biology were reviewed to situate the gender socialization process during adolescence in a broader context of multi level influences. Second, a socio ecological framework was introduced to bring together the main factors that influence the gender socialization process and its outcomes. Third, knowledge on how to influence the gender socialization process and its outcomes was summarized in order to provide practical recommendations for policies and programmes.  The paper concludes with recommendations for more holistic policy and programming efforts around gender socialization in adolescence.
A Tandem Organic Photovoltaic Cell with 19.6% Efficiency Enabled by Light Distribution Control.
Venue: Advanced materials
Year: 2021

Despite more potential in realizing higher photovoltaic performance, the highest power conversion efficiency (PCE) of tandem organic photovoltaic (OPV) cells still lags behind that of state of the art single junction cells. In this work, highly efficient double junction tandem OPV cells are fabricated by optimizing the photoactive layers with low voltage losses and developing an effective method to tune optical field distribution. The tandem OPV cells studied are structured as indium tin oxide (ITO)/ZnO/bottom photoactive layer/interconnecting layer (ICL)/top photoactive layer/MoOx /Ag, where the bottom and top photoactive layers are based on blends of PBDB TF:ITCC and PBDB TF:BTP eC11, respectively, and ICL refers to interconnecting layer structured as MoOx /Ag/ZnO:PFN Br. As these results indicate that there is not much room for optimizing the bottom photoactive layer, more effort is put into fine tuning the top photoactive layer. By rationally modulating the composition and thickness of PBDB TF:BTP eC11 blend films, the 300 nm thick PBDB TF:BTP eC11 film with 1:2 D/A ratio is found to be an ideal photoactive layer for the top sub cell in terms of photovoltaic characteristics and light distribution control. For the optimized tandem cell, a PCE of 19.64% is realized, which is the highest result in the OPV field and certified as 19.50% by the National Institute of Metrology.
Tug of war between driver and passenger mutations in cancer and other adaptive processes
Venue: Proceedings of the National Academy of Sciences
Year: 2014

During rapid adaptation, populations start in hostile conditions and must evolve new traits to survive. Development of cancer from a population of precancerous cells within a body is an example of such rapid adaptation. New traits required for cancer progression are acquired by driver mutations in a few key genes. Most mutations, however, are unimportant for progression and can be damaging to cancer cells, termed "passengers." The role these damaging passengers play in cancer and other adaptive processes is unknown. Here we show that driver mutations engage in a tug of war with damaging passengers. This tug of war explains many phenomena in oncology, suggesting how to develop new therapies and target existing therapies to exploit damaging passengers. Cancer progression is an example of a rapid adaptive process where evolving new traits is essential for survival and requires a high mutation rate. Precancerous cells acquire a few key mutations that drive rapid population growth and carcinogenesis. Cancer genomics demonstrates that these few driver mutations occur alongside thousands of random passenger mutations a natural consequence of cancer's elevated mutation rate. Some passengers are deleterious to cancer cells, yet have been largely ignored in cancer research. In population genetics, however, the accumulation of mildly deleterious mutations has been shown to cause population meltdown. Here we develop a stochastic population model where beneficial drivers engage in a tug of war with frequent mildly deleterious passengers. These passengers present a barrier to cancer progression describable by a critical population size, below which most lesions fail to progress, and a critical mutation rate, above which cancers melt down. We find support for this model in cancer age incidence and cancer genomics data that also allow us to estimate the fitness advantage of drivers and fitness costs of passengers. We identify two regimes of adaptive evolutionary dynamics and use these regimes to understand successes and failures of different treatment strategies. A tumor's load of deleterious passengers can explain previously paradoxical treatment outcomes and suggest that it could potentially serve as a biomarker of response to mutagenic therapies. The collective deleterious effect of passengers is currently an unexploited therapeutic target. We discuss how their effects might be exacerbated by current and future therapies.

Min Sum Algorithm Using Multi Edge Type Normalized Scheme for ATSC 3.0 LDPC Decoders
Venue: IEEE Transactions on Broadcasting
Year: 2020

To offer commercial LDPC decoders with better performance, in this paper, multi edge type (MET) normalized scheme is proposed to improve the performance of traditional min sum algorithm (MSA) and its modified versions. With respect to sum product algorithm (SPA) we firstly analyze and find out that the degradations of convergence in different edge types are distinct in MSA theoretically. To compensate the different degradations above, proposed MET normalized scheme is used in normalized min sum algorithm (MET NMSA) In addition, MET based density evolution (MET DE) is also presented to search optimized MET scaling factors for MET NMSA. To further verify the validity of MET normalized scheme, Advanced Television Systems Committee (ATSC) 3.0 LDPC codes are used to evaluate MET NMSA in comparison with the conventional algorithms, i.e. normalized min sum algorithm (NMSA) offset min sum algorithm (OMSA) and variable scaling normalized min sum algorithm (VS NMSA) Extensive simulation results show that MET NMSA for ATSC 3.0 LDPC decoders has at most 1.53dB, 0.21dB and 0.35dB gain over NMSA, OMSA and VS NMSA respectively when frame error rate (FER) is at 10 4 level over additive white Gaussian noise (AWGN) channels using QPSK modulation.
The e puck, a Robot Designed for Education in Engineering
Year: 2009

Mobile robots have the potential to become the ideal tool to teach a broad range of engineering disciplines. Indeed, mobile robots are getting increasingly complex and accessible. They embed elements from diverse fields such as mechanics, digital electronics, automatic control, signal processing, embedded programming, and energy management. Moreover, they are attractive for students which increases their motivation to learn. However, the requirements of an effective education tool bring new constraints to robotics. This article presents the e puck robot design, which specifically targets engineering education at university level. Thanks to its particular design, the e puck can be used in a large spectrum of teaching activities, not strictly related to robotics. Through a systematic evaluation by the students, we show that the e puck fits this purpose and is appreciated by 90 percent of a large sample of students.
Zonula occludens 2 regulates Rho proteins activity and the development of epithelial cytoarchitecture and barrier function.
Venue: Biochimica et biophysica acta. Molecular cell research
Year: 2017

Silencing Zonula occludens 2 (ZO 2) a tight junctions (TJ) scaffold protein, in epithelial cells (MDCK ZO 2 KD) triggers: 1) Decreased cell to substratum attachment, accompanied by reduced expression of claudin 7 and integrin b1, and increased vinculin recruitment to focal adhesions and stress fibers formation; 2) Lowered cell cell aggregation and appearance of wider intercellular spaces; 3) Increased RhoA/ROCK activity, mediated by GEF HI recruitment to cell borders by cingulin; 4) Increased Cdc42 activity, mitotic spindle disorientation and the appearance of cysts with multiple lumens; 5) Increased Rac and cofilin activity, multiple lamellipodia formation and random cell migration but increased wound closure; 6) Diminished cingulin phosphorylation and disappearance of planar network of microtubules at the TJ region; and 7) Increased transepithelial electrical resistance at steady state, coupled to an increased expression of ZO 1 and claudin 4 and a decreased expression of claudin 2 and paracingulin. Hence, ZO 2 is a crucial regulator of Rho proteins activity and the development of epithelial cytoarchitecture and barrier function.
THE ADAPTATION OF CINDERELLA STORY IN JAPANESE TELEVISION DRAMA HANA NOCHI HARE
Year: 2019

Fairy tales have positive benefits to spread educational and moral values to society. However, most fairy tales have the same pattern, weakening women's position and strengthening men's, such as the Cinderella tale. This study aims to find differences from the drama Hana Nochi Hare which was adapted from the fairy tale of Cinderella. This study will use adaptation theory from Linda Hutcheon (2006) with descriptive analysis methods and feminist perspective reading. From the results of the analysis, there were two major differences in the fairy tales and the drama, the potrayal of the female lead character and the relations between female and male characters. Hana Nochi Hare featured the lead character as a "Feminist Cinderella" who tries to break the order and restrictions on gender in Cinderella fairy tales and offers a new gender relations between male and female character, in which the female character is the one who saved the male character. Linked to gender issues in Japan during the drama production year, the television drama Hana Nochi Hare can be seen as a reflection of Japanese patriarchal society nowadays.

Knowledge and attitudes of pregnant women towards anaesthetic techniques for caesarean delivery in a North Central Teaching Hospital
Year: 2016

As caesarean deliveries increase globally, more women will be exposed to anaesthesia as part of the surgical procedures. Evaluation of the knowledge and attitudes of parturient will guide patient education and counselling and may improve overall satisfaction with caesarean delivery. This was a cross sectional study involving parturient aged 21 47 years scheduled for elective caesarean delivery at the University of Ilorin Teaching Hospital, Ilorin, Nigeria. Sampling method was purposive, informed consent was obtained from all participants and data collection was through an interviewer administered questionnaire. Data analysis was by SPSS version 20.0 and p<0.05 was significant. Awareness about anaesthetic techniques for caesarean delivery was 85(78% but 31 (37% were adequately informed about the techniques. The preferences of parturient for specific anaesthetic techniques favoured regional anaesthesia (spinal [68.3% epidural [5% compared to general anaesthesia (18.3% Educational level, previous anaesthetic experience, types of occupation, partner's level of education among others had likelihood of improving the knowledge and choice of anaesthetic techniques for caesarean delivery among the respondents. Conclusion from the study revealed that spinal anaesthesia was preferred for caesarean delivery similar to the global trend due to its perceived safety. Adequate information at antenatal clinic and involvement of anaesthestists may help to improve knowledge and acceptance of anaesthetic techniques by parturient.

Two intermittent vismodegib dosing regimens in patients with multiple basal cell carcinomas (MIKIE) a randomised, regimen controlled, double blind, phase 2 trial.
Venue: The Lancet. Oncology
Year: 2017

Vismodegib, a first in class Hedgehog pathway inhibitor, is approved for use in adults with advanced basal cell carcinoma. Patients with multiple basal cell carcinomas, including those with basal cell nevus (Gorlin) syndrome, need extended treatment. We assessed the safety and activity of two long term intermittent vismodegib dosing regimens in patients with multiple basal cell carcinomas.  In this randomised, regimen controlled, double blind, phase 2 trial, we enrolled adult patients with multiple basal cell carcinomas, including those with basal cell nevus syndrome, who had one or more histopathologically confirmed and at least six clinically evident basal cell carcinomas. From a centralised randomisation schedule accessed via an interactive voice or web based response system, patients were randomly assigned (1:1) to treatment group A (150 mg oral vismodegib per day for 12 weeks, then three rounds of 8 weeks of placebo daily followed by 12 weeks of 150 mg vismodegib daily) or treatment group B (150 mg oral vismodegib per day for 24 weeks, then three rounds of 8 weeks of placebo daily followed by 8 weeks of 150 mg vismodegib daily) Treatment assignment was stratified by diagnosis of basal cell nevus syndrome, geographical region, and immunosuppression status. The primary endpoint was percentage reduction from baseline in the number of clinically evident basal cell carcinomas at week 73. The primary analysis was by intention to treat. The safety population included all patients who received at least one dose of study drug.  Between April 30, 2013, and April 9, 2014, 229 patients were randomly assigned treatment, 116 in treatment group A and 113 in treatment group B. The mean number of basal cell carcinoma lesions at week 73 was reduced from baseline by 62*7% (95% CI 53*0 72*3) in treatment group A and 54*0% (43*6 64*4) in treatment group B. 216 (95% of 227 patients included in the safety analysis had at least one treatment emergent adverse event deemed to be related to study treatment (107 [94% of 114 in treatment group A and 109 [97% of 113 in treatment group B) The most common grade 3 or worse treatment related adverse events were muscle spasms (four [4% patients in treatment group A vs 12 [11% in treatment group B) increased blood creatine phosphokinase (one [1% vs four [4% and hypophosphataemia (zero vs three [3% Serious treatment emergent events were noted in 22 (19% patients in treatment group A and 19 (17% patients in treatment group B. Four (2% patients died from adverse events; one (pulmonary embolism in treatment group A) was possibly related to treatment.  Both intermittent dosing schedules of vismodegib seemed to show good activity in long term regimens in patients with multiple basal cell carcinomas. Further study is warranted.  F Hoffmann La Roche.
Design and implementation of class F GaN HEMT power amplifier for S band radar
Venue: 2017 International Conference on Electrical, Electronics, Communication, Computer, and Optimization Techniques (ICEECCOT)
Year: 2017

The increased development in the telecommunication domain, the telecom equipments are required to operate at high speeds and these equipments consumes high amount of power. Hence, increasing the durability of the battery is of great concern. The front end equipment of the wireless system is the Power Amplifier (PA) Most of the wireless communication TV transmission, radar RF power amplifier are considered as one of the most critical design block. An implementation of class F amplifier using Gallium Nitride (GaN) which belongs to the family of High Electron Mobility Transistor (HEMT) is realized in this paper. The GaN technology is employed because of wider bandgap and higher carrier concentration. Elements having wide bandgap, exhibits high breakdown voltage as well as high power density. This facilitates a transistor of small physical dimension to generate high output power. Here, the design of class F amplifier with harmonic load network is presented using microstrip transmission lines. The class F PA for a frequency of 2.4GHz is designed and operated in linear region using ADS    The transistor model, CGH40010F Cree having a rating of 10W is used for the proposed design. The class F amplifier implemented in this work can produce an output power of 41.818dBm which is 15.19W, with higher PAE of 78.8% and a gain of 20dB. Electromagnetic simulator is used to get accurate results and to verify the S parameters. The simulator computes the response of the proposed structure from the physical geometry using Maxwell's equations. From the simulation results, the input reflection coefficient is obtained as 13.872dB and output reflection coefficient is 14.017dB. The design was able to achieve a gain of 20dB and output power is obtained as 14.44W with 75.29% efficiency.
Extending the reach of multi tier sustainable supply chain management Insights from mineral supply chains
Venue: International Journal of Production Economics
Year: 2019

Triadic or tetradic multi tier sustainable supply chain management (MT SSCM) research emerged recently to reach out towards raw material suppliers and to address their often severe sustainability impacts. This is especially relevant in mineral supply chains (SCs) which consist of a commodity chain upstream and an end product chain downstream. To comprehensively investigate the reach of MT SSCM in mineral SCs, the extant Delphi study brought together 44 global authors on sustainability in mineral SCs. They contributed their professional knowledge in three questionnaire rounds, which systematically identify, evaluate and contrast the sustainability challenges in mineral SCs. As a result, a generic mineral SC structure is derived and 17 major sustainability issues are identified. Moreover, the findings reveal that all but two sustainability issues need to be addressed in the upstream SC. As mineral SCs might comprise up to nine tiers, the most impactful tiers lie outside the reach of current MT SSCM concepts, which are limited to triads or tetrads by the visible horizon or lacking power of the focal firm. We thus propose a cascaded MT SSCM approach which links the up and downstream SC parts. Moreover, individual focal firms for each SC part are defined, which build a direct strategic link. This link enables that tailored managerial responses can be cascaded into the respective SC parts, where the individual sustainability issues can best be addressed. This cascaded design represents a novel approach in MT SSCM which multiplies existing concepts. Moreover, the challenges and opportunities, which the cascaded approach raises for MT SSCM research are discussed and outlined.
