Numerical Investigation of Different Core Topologies in Sandwich-Structured Composites Subjected to Air-Blast Impact
Get PDFAir-blast loading is a serious threat to military and civil vehicles, buildings, containers, and cargo. Applications of sandwich-structured composites have attracted increasing interest in modern lightweight design and in the construction of dynamic loading regimes due to their high resistance against blast and ballistic impacts. The functional properties of such composites are determined by the interplay of their face sheet material and the employed core topology. The core topology is the most important parameter affecting the structural behavior of sandwich composites. Therefore, this contribution presents a thorough numerical investigation of different core topologies in sandwich-structured composites subjected to blast loading. Special emphasis is put on prismatic and lattice core topologies displaying auxetic and classical non-auxetic deformation characteristics in order to illustrate the beneficial properties of auxetic core topologies. Their dynamic responses, elastic and plastic deformations, failure mechanisms, and energy absorption capabilities are numerically analyzed and compared. The numerical studies are performed by means of the commercial finite element code ABAQUS/Explicit, including a model for structural failure

History of Gloger family. The line of descent of Zygmunt Gloger’s son, Stanisław
No full textLiliana Gloger belongs to the fourth generation of Zygmunt Gloger’s descendants–she is his great-great-granddaughter. In the article, she outlines the line of descent of Zygmunt Gloger’s son, Stanisław. The information is taken primarily from the reminiscences of Gloger’s granddaughter, Irena Matuszewicz, and the author’s grandmother, Alicja Gloger-Łukaszewska, as well as from different family documents. Despite the fact that in Liliana Gloger’s nearest family there has been nobody who could pass on to her the Gloger tradition, she has been brought up in the spirit of respect for the family roots, notably the musicality and passion for arts of its various members. Her grandmother, Alicja Gloger-Łukaszewska, was a charismatic popularizer of Polish culture. Her fascination with local history, art, nature, culture and science became inspirational for other family members and a few generations of her students.Liliana Ewa Gloger – praprawnuczka Zygmunta Glogera, córka Bohdana, urodzona w 1976 roku w Szczytnie, prawniczka.

Formalization of Orthogonal Decomposition for Hilbert Spaces
No full textIn this article, we formalize the theorems about orthogonal decomposition of Hilbert spaces, using the Mizar system [1], [2]. For any subspace S of a Hilbert space H, any vector can be represented by the sum of a vectorin S and a vector orthogonal to S. The formalization of orthogonal complements of Hilbert spaces has been stored in the Mizar Mathematical Library [4]. We referred to [5] and [6] in the formalization.Hiroyuki Okazaki, Shinshu University, Nagano, JapanGrzegorz Bancerek, Czesław Byliński, Adam Grabowski, Artur Korniłowicz, Roman Matuszewski, Adam Naumowicz, Karol Pąk, and Josef Urban.

Farmers’ Perceptions on an Irrigation Advisory Service: Evidence from Tunisia
Get PDFDecisions on irrigation water management are usually made at different levels, including farms, water user associations (WUAs), and regional water planning agencies. The latter generally have good access to information and decision tools regarding water resources management. However, these remain out of reach to the final water users, namely the farmers. The study, conducted in the irrigated district of Cherfech, north Tunisia, had the main objective of investigating farmer’s perceptions of, and acceptance for, the use of an irrigation advisory service (IAS) to be implemented by their WUA. The suggested IAS provides the following information: (1) reference evapotranspiration (ETo) and rainfall; (2) crop water requirement (CWR) of the most cultivated crops; (3) irrigation water requirement (IWR) of the farmer’s crop; and (4) crop monitoring and real-time estimation of IWR of crops settled, using soil moisture sensors. Such services and information would be available at the WUA level and provided in a timely manner to farmers for more effective decision making at the plot level. Prior to the acceptance study, we launched a technical study to determine the required tools and equipment required for the implementation of the IAS, followed by a farmer survey to assess their respective perceptions and acceptance towards this IAS. Results showed that only 54% of the farmers are satisfied by WUAs work, but that 77% of them accepted using the suggested IAS. Farmers are also willing to pay for most of the IAS packages suggested. The financial profitability of investing in the IAS at the WUA level shows the venture is financially viable, with a benefit cost ratio (BCR) of 1.018. The project will be even more profitable if we add the social benefits, which may result in water savings at the WUA level
An Integrated Assessment Framework for Transition to Water Circularity
Get PDFChanging our unsustainable linear water management pattern is necessary to face growing global water challenges. This article proposes an integrated framework to analyse and understand the role of different contextual conditions in the possible transition towards water circularity. Our framework combines a systematic multi-level perspective to explore the water system and the institutional work theory for technology legitimation. The framework consists of the following stages: (1) describing and understanding the water context, (2) assessment of the selected technologies’ circularity level, (3) assessment of the alternative circular technologies’ legitimacy, and (4) identification of the legitimation actions to support the upscale of alternative circular technologies. The practical applicability of the integrated assessment framework and its four assessment stages was demonstrated in the exploration of circular water technologies for the horticulture sector in Westland, the Netherlands. The results revealed the conditions that hinder or enable the legitimation of the circular water technologies, such as political environmentalism, trust in water governing authorities, and technical, financial, and knowledge capabilities
The Optimization of Dispersion and Application Techniques for Nanocarbon-Doped Mixed Matrix Gas Separation Membranes
Get PDFIn this work, supported cellulose acetate (CA) mixed matrix membranes (MMMs) were prepared and studied concerning their gas separation behaviors. The dispersion of carbon nanotube fillers were studied as a factor of polymer and filler concentrations using the mixing methods of the rotor–stator system (RS) and the three-roll-mill system (TRM). Compared to the dispersion quality achieved by RS, samples prepared using the TRM seem to have slightly bigger, but fewer and more homogenously distributed, agglomerates. The green γ-butyrolactone (GBL) was chosen as a polyimide (PI) polymer-solvent, whereas diacetone alcohol (DAA) was used for preparing the CA solutions. The coating of the thin CA separation layer was applied using a spin coater. For coating on the PP carriers, a short parameter study was conducted regarding the plasma treatment to affect the wettability, the coating speed, and the volume of dispersion that was applied to the carrier. As predicted by the parameter study, the amount of dispersion that remained on the carriers decreased with an increasing rotational speed during the spin coating process. The dry separation layer thickness was varied between about 1.4 and 4.7 μm. Electrically conductive additives in a non-conductive matrix showed a steeply increasing electrical conductivity after passing the so-called percolation threshold. This was used to evaluate the agglomeration behavior in suspension and in the applied layer. Gas permeation tests were performed using a constant volume apparatus at feed pressures of 5, 10, and 15 bar. The highest calculated CO2/N2 selectivity (ideal), 21, was achieved for the CA membrane and corresponded to a CO2 permeability of 49.6 Barrer
Entwicklung eines Vorgehensmodells zum Aufbau einer Taxonomie von Standardmechanismen im Bereich von Gamification
Get PDFIn dieser Arbeit wird ein Vorgehensmodell entwickelt um eine Taxonomie für Spielmechaniken aufzubauen. Hierfür werden zwei Vorgehensmodelle miteinander verbunden: eines, das die Extraktion von Spielmechaniken aus Gesellschaftsspielen in verschiedenen Strategien ermöglicht sowie ein weiteres, das ein standardisiertes Vorgehen beschreibt, wie eine Taxonomie aufgebaut werden kann.
Innerhalb des Vorgehensmodell zum Taxonomieaufbau werden die Strategien zur Extraktion von Spielmechaniken zum Aufbau des Domänenverständnisses genutzt. Davon ausgehend werden Kategorien abstrahiert, welche im Nachgang verfeinert und zueinander in Bezug gesetzt werden. Anschließend werden die zusätzlich extrahierten Spielmechaniken in die neu aufgestellte Struktur anhand der identifizierten Kriterien integriert und auf Kohärenz geprüft.In this thesis a procedure model is developed to build a taxonomy for game mechanics. For this purpose, two process models are combined: one that allows the extraction of game mechanics from parlor games in different strategies and another that describes a standardized procedure for building a taxonomy.
Within the procedure model for building taxonomies, the strategies for extracting game mechanics are used to build domain understanding. Based on this, categories are abstracted, which are subsequently refined and related to each other. Subsequently, the additionally extracted game mechanics are integrated into the newly established structure using the identified criteria and checked for coherence
Analysis of ENSO-Driven Variability, and Long-Term Changes, of Extreme Precipitation Indices in Colombia, Using the Satellite Rainfall Estimates CHIRPS
Get PDFClimate change includes the change of the long-term average values and the change of the tails of probability density functions, where the extreme events are located. However, obtaining average values are more straightforward than the high temporal resolution information necessary to catch the extreme events on those tails. Such information is difficult to get in areas lacking sufficient rain stations. Thanks to the development of Satellite Precipitation Estimates with a daily resolution, this problem has been overcome, so Extreme Precipitation Indices (EPI) can be calculated for the entire Colombian territory. However, Colombia is strongly affected by the ENSO (El Niño—Southern Oscillation) phenomenon. Therefore, it is pertinent to ask if the EPI’s long-term change due to climate change is more critical than the anomalies due to climate variability induced by the warm and cold phases of ENSO (El Niño and La Niña, respectively). In this work, we built EPI annual time series at each grid-point of the selected Satellite Precipitation Estimate (CHIRPSv2) over Colombia to answer the previous question. Then, the Mann-Whitney-Wilcoxon test was used to compare the samples drawn in each case (i.e., change tests due to both long-term and climatic variability). After performing the analyses, we realized that the importance of the change depends on the region analyzed and the considered EPI. However, some general conclusions became evident: during El Niño years (La Niña), EPI’s anomaly follows the general trend of reduction -drier conditions- (increase; -wetter conditions-) observed in Colombian annual precipitation amount, but only on the Pacific, the Caribbean, and the Andean region. In the Eastern plains of Colombia (Orinoquía and Amazonian region), EPI show a certain insensitivity to change due to climatic variability. On the other hand, EPI’s long-term changes in the Pacific, the Caribbean, and the Andean region are spatially scattered. Still, long-term changes in the eastern plains have a moderate spatial consistency with statistical significance
