Dazu wurden die Qualit{\"a}tskriterien frischer und getrockneter Agrarprodukte analysiert und die Ver{\"a}nderungen durch die unterschiedlichen Trocknungsparameter, wie Luftgeschwindigkeit, Taupunkttemperatur, Trocknungstemperatur und -zeit dargestellt. In einer Literaturrecherche wurden sowohl die Faktoren f{\"u}r die Nachernteverluste und deren H{\"o}he in Industrie- sowie Schwellen- und Entwicklungsl{\"a}nder untersucht. Zudem sind die Agrarprodukte und deren qualit{\"a}tsbestimmenden Inhaltsstoffe vorgestellt. Auch die Extraktions- sowie die Analyse-Methoden werden aufgezeigt und erkl{\"a}rt. Dabei handelt es sich um die Hochleistungsfl{\"u}ssigkeit- und die Ionenausschlusschromatographie, aber auch um die UV/Vis-Spektroskopie und die Polarimetrie. Des Weiteren wurden w{\"a}hrend den Trocknungsprozessen mit der integrierten Kamera des Trockners in definierten Zeitabst{\"a}nden Bilder aufgenommen und diese {\"u}ber eine speziell entwickelte Software im Hinblick auf die Farbver{\"a}nderung und die Schrumpfung der Agrarprodukte untersucht. Die Erstellung und {\"U}berpr{\"u}fung der Versuchsergebnisse fand mittels Statistik-Software statt. Es wurden neue Diagramme, sogenannte Sch{\"a}digungsdiagramme, eingef{\"u}hrt. Dabei handelt es sich um Diagramme, mit deren Hilfe die Identifizierung optimaler Trocknungsprozesse m{\"o}glich ist. F{\"u}r Chilis erwies sich eine Trocknungstemperatur von ~ 60 °C, f{\"u}r Kartoffeln von ~ 64 °C bis 74 °C, f{\"u}r Ananas von ~ 43 °C und Mangos von ~ 60 °C als optimal. Auch Taupunkttemperaturen von ~ <12 °C / >27 °C f{\"u}r Chilis, ~ 30 °C f{\"u}r Kartoffeln, ~ 14 °C f{\"u}r Ananas und ~ 20 °C Mangos waren optimal.

This is even more true at the rise of new deep learning methods which heavily rely on the availability of training data. But even for traditional, hand crafted algorithms that are not trained on data, reliable test data is important for the improvement and evaluation of the methods. Because ground truth acquisition is expensive and time consuming, semi-automatic methods are introduced which make use of suggestions coming from document analysis systems. The interaction between the human operator and the automatic analysis algorithms is the key to speed up the process while improving the quality of the data. The final confirmation of data may always be done by the human operator. This paper demonstrates a use case for acquisition of truth data in a mail processing system. It shows why a new, extended view on truth data is necessary in development and engineering of such systems.

Findings - Visitors want an application that provides real-time forecasts of issues such as traffic, parking and queues and, at the same time, enables them to create a personal activity schedule based on this information.

Practical implications - The results may lead to an optimization and management separation of mobility flows in the research area and be helpful to municipal planners, destination marketing organizations and visitors. Originality/value - The German border cities of Konstanz, Radolfzell and Singen in the Lake Constance region need improved visitor management, mainly because of a high level of shopping tourism by Swiss visitors to Germany.

Although, many solutions for LQE have been proposed in literature, the majority of them are not designed specifically for 6TiSCH networks. In this paper, we analyze the performance of existing LQE strategies on 6TiSCH networks. First, we run a set of simulations to measure the performance of one existing LQE strategy in 6TiSCH. Our simulations show that such strategy can result in measurements with low accuracy due to the 6TiSCH default timeslot allocation strategy. Consequently, we propose an extension of the 6TiSCH Minimal Configuration that allocates specific timeslots for the transmission of probing messages to mitigate the problem.

Their functional properties combined with excellent biocompatibility increase the possibility and the performance of minimally invasive surgeries. Overviews of existing applications can be found in [1-2]. Within the medical field, most of the applications with shape memory (SM) material take advantage of the superelasticity of NiTi SMAs. In contradiction to the superelastic or mechanical SM effect, the application described in this study uses the thermal SM effect for a new medical implant. Before explaining the SM driven intramedullary bone nail in detail, a short introduction to the bone elongation technique is given. The background of this application on based in the medical fact that normally any tissue reacts to an injury with repair and healing processes through multiplication of cells. If after a transverse osteotomy a strain stimulus is activated, for example by tensile stress, this multiplication of cells and new formation of tissue may be continued for any length of time. Due to this mechanism, even considerable loss of bone caused by fractures or congenital defective positions, may be compensated without bone grafts. The technique of callus distraction by means of external fixation or intramedullary nail stimulates the formation of callus in the bone gap. Callus is the repair tissue of the bone generated in the fracture gap in case of bone fracture or osteotomy. The gap to be bridged should not be wider than 1 mm per day [3]. The process starts with the exudation of callus around the ends of the broken bone. At first, callus is more like a fibrous tissue. Later it hardens due to deposition of calcium and eventually it is converted into true bone. Three weeks after severance, the vascular system is formed. An overview of current bone lengthening techniques, also called callus distraction, can be found in [3]. External systems are normally used for the extension of bones, the bone fragments being fixed on rings by wires. The decisive disadvantages of those external systems are primarily the considerable risk of infection due to protruding wires, noticeable discomfort for the patient because of the external rings, a coarse cosmetic result because of scarring, as well as rather long hospitalization. Therefore, internal bone extension systems are of great interest to orthopedic surgery.}, language = {en} } @phdthesis{Rajab, author = {Rajab, Mohammed}, title = {Channel and source coding for non-volatile flash memories}, series = {Schriftenreihe der Institute f{\"u}r Systemdynamik (ISD) und optische Systeme (IOS)}, publisher = {Springer Vieweg}, address = {Wiesbaden}, isbn = {978-3-658-28981-2}, doi = {10.1007/978-3-658-28982-9}, pages = {XVI, 143}, abstract = {NAND flash memory is widely used for data storage due to low power consumption, high throughput, short random access latency, and high density. The storage density of the NAND flash memory devices increases from one generation to the next, albeit at the expense of storage reliability. Our objective in this dissertation is to improve the reliability of the NAND flash memory with a low hard implementation cost. We investigate the error characteristic, i.e. the various noises of the NAND flash memory. Based on the error behavior at different life-aging stages, we develop offset calibration techniques that minimize the bit error rate (BER). Furthermore, we introduce data compression to reduce the write amplification effect and support the error correction codes (ECC) unit. In the first scenario, the numerical results show that the data compression can reduce the wear-out by minimizing the amount of data that is written to the flash. In the ECC scenario, the compression gain is used to improve the ECC capability. Based on the first scenario, the write amplification effect can be halved for the considered target flash and data model. By combining the ECC and data compression, the NAND flash memory lifetime improves three fold compared with uncompressed data for the same data model. In order to improve the data reliability of the NAND flash memory, we investigate different ECC schemes based on concatenated codes like product codes, half-product codes, and generalized concatenated codes (GCC). We propose a construction for high-rate GCC for hard-input decoding. ECC based on soft-input decoding can significantly improve the reliability of NAND flash memories. Therefore, we propose a low-complexity soft-input decoding algorithm for high-rate GCC.}, language = {en} } @incollection{SeligGasserBaltes, author = {Selig, Christoph J. and Gasser, Tim and Baltes, Guido H.}, title = {Effects of internal corporate venturing on the transformation of established companies}, series = {Digital Entrepreneurship : interfaces between digital technologies and entrepreneurship}, publisher = {Springer}, address = {Cham}, isbn = {978-3-030-20138-8}, doi = {10.1007/978-3-030-20138-8_7}, pages = {159 -- 183}, abstract = {The organizational capability to adapt to the fast and radical changes of market parameters becomes a prerequisite for companies' long-term survival. In this context, organizational ambidexterity has gained much attention in research and practice. It is the capability to develop new businesses (exploration) while simultaneously optimizing the existing core businesses (exploitation). Established companies face several challenges in achieving this capability, as the underlying learning modes of exploration and exploitation are mutually incompatible. One way to solve these challenges is to separate the exploration-oriented part from the core organization. Corporate venturing has been widely recognized as one tool to create these dual structures to develop new businesses, based on discontinuous innovation. In recent times, new corporate venturing forms emerge in practice. This growing number of different forms has led to new applications of corporate venturing which go beyond the pure development of new businesses, toward supporting the entrepreneurial transformation of companies. This study aims at answering how different corporate venturing forms contribute to the strategic renewal of established companies. For this purpose, qualitative research methods are used to analyze data from 17 interviews conducted in two German high-tech companies. The study at hand provides empirical evidence in the field of corporate venturing by uncovering new insights about the different transformational effects of corporate venturing initiatives on the core organization. It further reveals that corporate venturing forms can be classified into two categories according to their respective level of entrepreneurship and frequency of execution. Both categories exhibit different transformational effects and can be understood as being complementary to each other.}, language = {en} } @inproceedings{LangBaltes, author = {Lang, Christina and Baltes, Guido H.}, title = {Entrepreneurial employees}, series = {IEEE International Conference on Engineering, Technology and Innovation (ICE/ITMC), 17-19 June 2019, Valbonne Sophia-Antipolis, France}, publisher = {IEEE}, isbn = {978-1-7281-3401-7}, doi = {10.1109/ICE.2019.8792653}, pages = {11}, abstract = {Volatile markets and accelerating innovation cycles progressively force established companies to adopt alternative innovation strategies such as entrepreneurship.

Usually, analogue sensor data is sampled at rates far exceeding the Nyquist-rate containing substantial amounts of redundancies and noise, imposing high computational loads due to the subsequent and necessary feature processing chain (generation, dimensionality reduction, rating and selection). To overcome these problems, Compressed Sensing can be used to sample directly to a compressed space, provided the signal at hand and the employed compression/measurement system meet certain criteria. Theory states, that during this compression step enough information is conserved, such that a reconstruction of the original signal is possible with high probability. The proposed approach however does not rely on reconstructed data for condition monitoring purposes, but uses directly the compressed signal representation as feature vector. It is hence assumed that enough information is conveyed by the compression for condition monitoring purposes. To fuse the compressed coefficients into one health index that can be used as input for remaining useful life prediction algorithms and is limited to a reasonable range between 1 and 0, a logistic regression approach is used. Run-to-failure data of three translational electromagnetic actuators is used to demonstrate the health index generation procedure. A comparison to the time domain ground truth signals obtained from Nyquist sampled coil current measurements shows reasonable agreement. I.e. underlying wear-out phenomena can be reproduced by the proposed approach enabling further investigation of the application of prognostic methods.}, language = {en} } @inproceedings{LebedevNevzorovaKlimenkoetal., author = {Lebedev, Georgy and Nevzorova,, Diana and Klimenko, Herman and Shaderkin, Igor and Kim, Sergey and Ashenbrenner, Inna and Seepold, Ralf}, title = {The use of digital technology in palliative care}, series = {EMBC Workshop "Telemedicine and Telemonitoring in AAL Home Environments", 41st Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC 2019), 23 July 2019, Messe Berlin, Germany}, editor = {Conti, Massimo and Lebedev, Georgy and Mart{\´i}nez Madrid, Natividad and Orcioni, Simone and Seepold, Ralf}, publisher = {Hochschule Reutlingen}, address = {Hochschule}, isbn = {978-3-00-063346-1}, doi = {10.34645/opus-2464}, pages = {43 -- 44}, abstract = {Due to the rising need for palliative care in Russia, it is crucial to provide timely and high-quality solutions for patients, relatives, and caregivers.
