In the present work, the electronic structure and the molecular distributions of four ILs on metal surfaces are discussed. A combination between two anions (which are [TfO] and [Tf2N]) and two cations (which are [EMim] and [BMP]) lead to a formation of [EMIm][TfO], [EMim][Tf2N], [BMP][TfO] and [BMP][Tf2N] ILs. As metal substrates Ti, Ni and Au were chosen. By using spin-coating a thin (2 ¿m) and ultrathin (approx. 10nm) ILs layers were achieved, which were subsequently studied by X-ray Photoelectron Spectroscopy. The stability of [Tf2N] anion based ILs depending on temperature was also shown in this work. Moreover, the stability of all used in this work ILs during the X-ray monochromatic radiation was studied.

Bluetooth Low Energy (BLE) is a short range, low power wireless networking technology that is increasingly used in various applications of the Internet of Things (IoT). The goals of this book is to design, implement, and evaluate simulation models for BLE focusing on multi device environments. Relevant performance metrics include the delay and energy consumption. Suitable abstraction of the different protocol layers has been defined to allow for implementing relevant aspects for the simulator. The simulation results are compared with real world hardware to measure the difference and to find the reasons for the differences.

In this book, sets of GIS-models for analyzing technical and social aspects of wind energy planning within the predefined priority areas in Schleswig-Holstein were developed. Then, the outputs of the GIS-models were used to classify priority areas based on their level of controversy. At the end, future exclusions of each class of priority areas under 4 scenarios was simulated to investigate the opportunity costs of eliminations. Technical approach in this paper included analyses of production cost, electricity generation, economic feasibility, turbines placements, hub-height, and opportunity costs. Regarding social approach, visibility as a contributing factor in changing landscape was taken into consideration. On this point, firstly, likelihood of visibility after sitting of wind turbines in all priority areas was simulated. Secondly, after considering effects of landcover, priority areas were classified based on their level of visual impact.

This book describes the procedure to calculate a numerical livelihood resilience index based on a theoretical framework. The index calculated in this book is based on the conceptual and analytical framework for characterising livelihood resilience described by Ifejika Speranza, Wiessmann and Rist (2014). The mapped resilience values are easy to understand and facilitate the communication of scientific results to a broad audience. Thanks to the explicit standardisation rules defined in this book, the calculated resilience values hold absolute character. This allows geographical and temporal comparison of different locations. The calculations can be applied to all countries that are predominantly rural and possess rich census data. All data used in this book is either from the 2009 Kenya Census or open-access data provided by the United Nations and other organisations. The resilience index calculated in this book combines high scientific quality, time efficiency and money effectiveness. Therefore, it shall be a stepping-stone in applied livelihood resilience research.

Do you have what it takes to succeed as a food startup? Most startups and companies struggle to successfully overcome the Valley of Death. The aim of this study was to assess the existence and effect of the Valley of Death on startups within the Swiss food sector. Personality characteristics in terms of emotional intelligence are largely responsible for successfully or non-successfully passing the Valley of Death. Within emotional intelligence, motivation and self-regulation of the entrepreneurs involved in a startup are key drivers. Besides timing, finances remain to be a crucial factor. Based on the results, a new term - the Mountain of Death - for Swiss food startups was introduced. Additionally, recommendations about how food startups best deal with several bottlenecks within this phase are extracted and summarized within a guideline. Although this phenomenon remains to be a complex issue and is subject to further investigations, the application of the created guideline should minimize the impact on food startups so that promising ideas are turned into profitable, commercial applications.
