Authors: Leser Hartmut , Löffler Jörg
Published: November 2021

Umweltprobleme nehmen kontinuierlich zu und werden komplexer! Die Landschaftsökologie beleuchtet die vielschichtige Problematik und zeigt Lösungen auf.
Der integrative Ansatz in der Landschaftsökologie gewinnt vor dem Hintergrund zahlreicher und komplexer Umweltprobleme immer mehr an Bedeutung. Dieses Lehrbuch liefert einen umfassenden Überblick über die Entwicklung der landschaftsökologischen Ansätze und Methoden.
Die Landschaftsökologie als interdisziplinäres Forschungsfeld ist vielschichtig und nach vielen Seiten offen. Die 5. Auflage des Lehrbuchklassikers wurde komplett neu bearbeitet und orientiert sich am state of the art.
Es gibt sowohl eine europäische und nordamerikanische Landschaftsökologie als auch eine eher geographisch-raumforscherisch und eine biogeographisch-biologisch ausgerichtete Landschaftsökologie.
Dieser konzeptionellen Vielfalt entspricht die Zentrierung auf die Begriffe Ökologie und Ökosystem, die im Mittelpunkt aller Kapitel stehen. Forschungsbeispiele aus verschiedenen Bereichen spannen den Bogen zur Praxis.
Die Landschaftsökologie ist ein gleichermaßen hochaktuelles wie spannendes Thema, das für Studierende vieler Fachrichtungen das Bewusstsein für den nachhaltigen und bewussten Umgang mit der Landschaft schärft und den Blick über den Tellerrand öffnet.

Failed Interventions: Domestic Violence, Human Trafficking, and the Criminalization of Survival
Authors: Richert Alaina
Published: November 2021

Over the last decade, state legislators have enacted statutes acknowledging the link between criminal behavior and trauma resulting from domestic violence and human trafficking. While these interventions take a step in the right direction, they still have major shortcomings that prevent meaningful relief for survivor-defendants. Until now, there has been no systematic overview of the statutes that require courts to consider a defendant’s history of trauma in the contexts of domestic violence and human trafficking. There has also been no attempt to explore how these statutes relate to each other. This Note fills those gaps. It also identifies essential elements future statutory interventions in these contexts must include in order to grant effective relief to survivor-defendants. These reforms are essential to create a legal system that does not criminalize surviving domestic violence and human trafficking.

W parku sekwoi. Hitchcock/Marker/Godard
Authors: Kita Barbara
Published: November 2021

Tekst stanowi refleksję na temat wzajemnych relacji Hitchcocka, Markera i Godarda. Główną ideą artykułu jest dostrzeżenie istotnego wpływu tego pierwszego na obu francuskich artystów, który w proponowanym ujęciu przejawia się w oddziaływaniu Zawrotu głowy (1958) na Pomost (1962), Bez słońca (1983) oraz Immemory (1997) Markera, a także na Nową falę (1990) i Historie kina (1988-1998) Godarda. Autorka zauważa, że francuscy reżyserzy wykorzystali ten sam film Hitchcocka, ale w nieco odmienny sposób. Obaj zaakcentowali uniwersalność opowieści o pamięci/zapominaniu oraz docenili kunszt twórcy thrillera, który był doskonałym, czułym na obraz stylistą. Jednak każdy z nich na swój sposób kreował postać Hitchcocka w swych dziełach. Marker podkreślał umiejętność manipulowania czasem i przestrzenią, doskonałość niemal ascetycznej formy zawartej w Hitchcockowskich prostych obrazach. Godard polegał zaś na Hitchcocku jako na mistrzu kina, następcy wielkich malarzy, który wywierał na publiczność ogromny wpływ dzięki umiejętności opowiadania filmowych historii obrazami.

Friction stir welding (FSW) can be made to improve the mechanical properties in the weld zone. This article aims to obtain the optimum FSW process parameters used for two plates of AA5083 welded joints. The significant factors in the FSW process are tool rotational speed(TRS), tool transverse speed(TTS), and the weld process conditions are Submerged FSW and Normal FSW. For doing the investigation, the Taguchi method L18 orthogonal array design of experimentation is utilized. Using the Grey Relational Analysis(GRA) to calculate the grey relation grade, the response parameters are tensile strength, microhardness, and surface roughness. The Optimum process parameters contain been recognized, and ANOVA controls the significant contribution of process parameters. The optimal FSW process parameters are used to maximize the FSW joint strength. It is identified in the condition of Submerged FSW, high tool rotational speed, and low TTS.

In recent years, the idea of using a mathematical model to describe the behavior of physical phenomena has been very much considered. Specifically, a definitive model, based on physical laws, enables researchers to calculate the number of time dependencies precisely at any moment in time. However, in the real world, we often face time-dependent phenomena with many unknown or unavailable factors (Lindley, 2010; Roulston et al., 2003). In this case, when it is not possible to achieve a definite - model, the prediction methods are wide used, especially when the past observations of a variable and primary relationships between specific observations are available. Forecasting methods that are used in different fields of science can be categorized based on various aspects. For example, the prediction methods used in the field of wind energy can be divided into four categories of 1) ultra short term (several seconds to four hours), 2) short term (4 to 24 hours), 3) medium-term (1 to 7 days), and 4) long term (more than 7 days) (Zack, 2003; Soman et al., 2010). Also, the structure of forecasting methods can be divided into two types of 1) single methods and 2) hybrid methods. Each of these categories can also be subdivided into smaller subgroups.

Crop and disease classification is one of the important problems in automation of agricultural processes with multi-cropping method where the field is cultivated with more than one crop. In order to solve this classification problem, a study has been carried out in the field cultivating eggplant (Solanum melongena) and tomato (Solanum lycopersicum) using the images obtained from a mobile phone camera. Textural descriptors namely contrast, correlation, energy and homogeneity were extracted from the gray-scale converted RGB image for crop identification, i.e., (tomato or eggplant) and the same descriptors were extracted from the gray-scale converted image from Hue Saturation Value (HSV) for disease classification (due to Cercospora leaf spot disease or two-spotted spider infestation). Discriminant analysis, Naive Bayes algorithm, support vector machine and neural network were the classification algorithms used with a resulting best accuracy of 97.61%, 95.62%, 98.01% and 98.94% for crop identification, 86.09%, 76.52%, 86.96% and 86.04% for disease classification respectively. Similarly, application of algorithm with 6 histogram-based descriptors for health status detection resulted in an accuracy of 66.67%, 37.04%, 50% and 72.9% respectively. Deep learning algorithm namely AlexNet was also evaluated which resulted in an accuracy of 100% for crop identification, 89.36% for health status detection and 81.51% for disease classification. Among the algorithms, AlexNet resulted in the best average accuracy of 90.29% for the above classification tasks.

Contextualized in the field of customer satisfaction in after-sales service in the automotive industry, the authors contribute to increasing customer satisfaction in three fundamental ways. First, by offering a new conceptual framework that integrates prior studies and Delphi methodology to survey the automotive industry's experts to identify essential and influential variables on customer satisfaction. Second, by developing a system dynamics and modeling method to evaluate the effect of these variables on each other, and unlimitedly investigate these variables' impact on customer satisfaction. Third, by offering an improvement scenario, we indicated what combination of observed and latent variables leads to a numerical increase in the customer satisfaction index. The survey's analytical results suggest that the cost of services and repair time is reduced by 30%, and the time of car acceptance in the repair shop is reduced by 20%. At the same time, the satisfaction with repair order description is increased by 30%, resulting in a 5% increase in numerical satisfaction with the overall service. Heretofore did not use a dynamic system model to determine the numerical amount of increasing customer satisfaction with after-sales service in the automotive industry. Therefore, the results of this study can be used as a basis for developing new policies in customer relationship management in automotive companies to increase customer satisfaction. This fact can lead to an increase in sales and ultimately the company's profitability. The article contributes to future research by quantitatively determining the number of changes in the significant factors to increase customer satisfaction.

This study is not only covers the historical aspects, but also analyzes the socio-cultural characteristics and seeks to find the factors which affect the perceptual geometry of houses. Hence the question is that how the perceptual geometry is in the houses in Tabriz and which factors cause differences in the perceptual geometry of houses. 30 houses built during Qajar era in Tabriz are investigated and analyzed as case studies. Then, they are categorized according to their similarities and differences. Given the nature of subject, the present study is based on logical reasoning and adopts an interpretive-historical methodology with an approach to content analysis. So in this study, the information is collected through library research and field investigations. A lot of valuable historical houses have survived in Tabriz, because the crown prince lived there in the Qajar dynasty and on the other hand, the city enjoyed economic prosperity due to the Silk Road. Differences are found based on the interpretation and analysis of perceptual geometry of Qajar houses in Tabriz and it is eventually concluded that perceptual geometry of the houses is not the same, so the discussions about Qajar houses in Tabriz should not be generalized to the same category.

Recently, the coronavirus pandemic has caused widespread panic around the world. Modern technologies can be used to monitor and control this highly contagious disease. A plausible solution is to equip each patient who is diagnosed with or suspected of having COVID-19 with sensors that can monitor various healthcare and location parameters and report them to the desired facility to control the spread of the disease. However, the simultaneous communication of numerous sensors installed in the majority of an area’s population results in a huge burden on existing Long-Term Evolution (LTE) networks. The existing network becomes oversaturated because it has to manage two kinds of traffic in addition to normal traffic (text, voice, and video): healthcare traffic generated by a large number of sensors deployed over a huge population, and extra traffic generated by people contacting their family members via video or voice calls. In pandemics, e-healthcare traffic is critical and should not suffer packet loss or latency due to network overload. In this research, we studied the performance of existing networks under various conditions and predicted the severity of network degradation in an emergency. We proposed and evaluated three schemes (doubling bandwidth, combining LTE-A and LTE-M networks, and request queuing) for ensuring quality of service (QoS) of healthcare sensor (HCS) network traffic without perturbation from routine human-to-human or machine-to-machine communications. Finally, we simulated all proposed schemes and compared them with existing network scenarios. The results have showed that when we have doubled the bandwidth the SCR of all traffic was 100% as same as the Queue strategy. However, when we prioritized the HCS traffic the SCR has recorded 100%, while H2H and M2M traffic has recorded 73%. When we used hybrid network LTE-A and LTE-M network, the HCS and H2H traffic has recorded 100% and M2M traffic has recorded 70%. After analyzing the results, we conclude that our proposed queuing schemes performed well in all conditions and provide the best QoS for HCS traffic.

Password alone is currently not trusted for user online authentication and security as threats from hackers continue to grow, requiring highly efficient defense safeguard protection against unauthorized users. Therefore, CAPTCHA techniques came into the picture as an automated assistance to distinguish between humans and robots. The CAPTCHA has several applications in the online security domain requiring to be merged with encrypted hash function benefitting from the facility of the graphical password schemes. This paper proposes engineering an authentication technique using graphical CAPTCHA with an AES encrypted hash password to maintain applicable security accessing systems. We propose three layered security system that joins highly efficient security mechanisms to avoid users’ stress of entering password many times or different other hectic routines in order to save account accessing.

This paper presents comparative experimental study’s results of diesel fuel and aviation fuel effect on operational properties of a high-pressure fuel pump of a common rail injection system. The two identical fuel injection systems mounted on a test bed of the fuel injection pumps were prepared for the experimental durability tests. The lubricity properties of diesel fuel and aviation fuel (Jet-A1) were studied using the High-Frequency Reciprocating Rig (HFRR) method. The values of wear scar diameter (WSD) obtained with Jet-A1 fuels were compared to the respective values measured with the reference diesel fuel. The microscopic photographs of the wear scar diameters obtained on above mentioned fuels are presented in the paper. The test results showed that long-term (about 300 hours) using aviation fuels produced a negative effect on the durability of the high-pressure fuel pump. Due to the wear of plunger-barrel units the decrease in the fuel delivery rate occurred of about 6.7 % operating with aviation fuel. The average friction coefficients of Jet-A1 fuels were higher than that of the normal diesel fuel.
Keywords: diesel fuel, aviation Jet-A1 fuel, lubricity, plunger-barrel units, wear scar diameter

Досліджено ключові елементів логістичного управління закупівлями для оборонного сектору у просторі. Встановлено, що тривалість процедури закупівлі на усіх стадіях займає часу набагато більше ніж фізична доставка предмету закупівлі. Причиною цього є де-факто відсутність логістичного управління системою матеріально-технічного забезпечення. Як наслідок – низький рівень практичного запровадження принципів логістики спрямованих на системне управління постачанням, що відповідає концепції логістики НАТО. Логістичне управління закупівлями для оборонного сектору дозволить скоординувати ресурси, техніку, інформацію і людей, оперативно, точно і злагоджено вирішувати поставлені завдання в умовах постійної нестабільності і зміни часових параметрів.
Ключові слова: логістичне управління, закупівлі, система матеріально-технічного забезпечення, принципи логістики постачання, оборонний сектор.
La interculturalidad, perspectivas en el contexto latinoamericano

Published: November 2021

El propósito de este artículo es reflexionar sobre interculturalidad como tema emergente en la modernidad, posmodernidad y su alcance, en el actual sistema político, en el contexto atinoamericano. Del análisis hecho e ideas expuestas se demuestra que, si las políticas públicas interculturales siguen desarrollándose en el actual sistema capitalista, no se podrá lograr los objetivos planificados debido a que, el sistema neoliberal, va generando formas jurídicas capaces de tergiversar el verdadero valor de los elementos culturales de los pueblos originarios (mercancías turísticas o patrimonio cultural de la humanidad). La interculturalidad debe ser una de las políticas públicas prioritarias en la esfera de la educación para el siglo XXI y, debe fundamentarse en; aprender a hacer, aprender a conocer, aprender a vivir juntos y aprender a ser, con más importancia en aprender hacer, es decir, todo individuo debe saber hacer, lo que aprendió y desarrolló en una universidad. Si esto no sucede entonces el sistema universitario habrá fracasado, sobre todo, quienes lo instruyen. Creemos que la interculturalidad funcional está contaminada porque fue desarrollada por y para el estado actual neoliberal. Más bien debe considerarse una interculturalidad objetiva sin ideologías que permita descolonizar el poder del ser y del saber. Una de las formas de ir fertilizando y preparando el terreno para el establecimiento de un nuevo sistema político y social, es generando partidos políticos y movimiento sociales, capaces de incorporar a la interculturalidad como elemento estructural y desarrollar liderazgo inclusivo.

PROVISION OF PRACTICE-ORIENTED PROFESSIONAL EDUCATION OF TEACHER TRAINING UNDERGRADUATES AT THE LESSONS OF LINGUODIDACTICS
Authors: Reutov M. I.
Published: November 2021

When lessons of linguodidactics are organized in a master course within the framework of the pedagogical program «Language Education», the literal understanding of the definition of linguodidactics as a general theory of mastering a foreign language in the learning environment often leads to the fact that undergraduates studying linguodidactics as an academic subject consider only theoretical issues. Understanding the relationship between linguodidactics and methods of teaching foreign languages as a relationship between theory and practice narrows the scope of the subject. As a result, the competencies included in its program are formed fragmentarily, i.e. the objectives of this subject contain only the knowledge of the theory which excludes the practical implementation of linguodidactic skills. The article describes linguodidactic skills and analyzes the experience of solving the stated problem by means of creating a system of practical work of undergraduates in the process of studying linguodidactics. The proposed training course is integrative. It combines fundamental and interdisciplinary areas in linguodidactics, and presupposes a smooth transition from studying the problems of the interaction of linguistic theory with the practice of teaching foreign languages to considering linguodidactic models of mastering a foreign language and forming a multicultural linguistic personality. The possibility of undergraduates’ putting into practice linguodidactic knowledge makes their theoretical reports more profound and instructive due to their examples from the practice of teaching foreign languages that confirm their theoretical propositions. It also stimulates their critical attitude to different teaching materials. The effectiveness of the organization of practical work at the lessons of linguodidactics is also a result of studying the interrelated modules of the subject and passing from a theoretical analysis of the process of mastering a foreign language to creating your own teaching materials on a strictly scientific basis. The research shows that the academic subject «Linguodidactics» has unlimited potential for the scientific organization of the educational and methodical work of future masters of science.

Published: November 2021

This study presents an overview of estimation methods to predict the actual project duration of Greek highway projects. Emphasis is given to the selection of the appropriate parameters that correlate with the actual project duration and to compare the performances of the main two methods, the linear regression (LR) with the neural network models (NN) based on data available at the bidding stage. In the context of the current research, thirty-seven highway projects were examined, constructed in Greece with similar available data like the extent, the type of work packages and the significance. Selection and ranking variables through correlation analyses using SPSS 25 has been carried on, in order to identify the most significant project variables. These include archeological findings, type of terrain, land expropriation, the existence of bridge, tunnel and embankment. Next step was the use of WEKA application, that highlighted the most efficient subset of variables. After the definition and grouping of the variables for actual duration prediction, these were used as input data for linear regression models (LR) and neural network models (NN). Various models have been created from each investigated method. While their performance and the comparison of linear regression and neural network models to estimate the actual duration of Greek highway projects are presented in this paper. Results’ discussion and conclusions along with limitations and further research are appropriately analyzed.
