Maßnahmen zum sozialverträglichen Wiederaufbau der zerstörten Wohngebäude in den informellen Siedlungen in Aleppo unter Würdigung historisch gewachsener Strukturen basierend auf soziokulturellen, planerischen, ökonomischen und baurechtlichen Aspekten.
(2022)
Durch den Bürgerkrieg wurden Teile im Osten Aleppos und insbesondere die sogenannten informellen Siedlungen, die einen Beitrag zur Wohnraumversorgung für etwa 1,00 bis 1,25 Mio. Menschen in Aleppo geleistet haben, am stärksten zerstört. Diese Zerstörungen stellen den Ausgangspunkt der vorliegenden Arbeit dar. Im Vergleich zum modernen Westen Aleppos, in dem freigestellte, zu Blöcken geordnete Mehrfamilienhäuser das Straßenbild bestimmen, sind die informellen Siedlungen als selbstorganisierte Siedlungen im Ostteil ...

Income and price elasticities of animal food demand and welfare in Indonesian urban: an application of the LA-AIDS
(2022-12-30)
Protein consumption can be a measure of the welfare of society. Developed countries consume more protein than developing countries. This study analyzes the effect of rising prices and income on demand and welfare in urban Indonesia. The research data use the 2018 Household National Socio-Economic Survey (Susenas) data in household consumption and expenditure data collected by the Central Statistics Agency (BPS). The number of samples is 133,873 households. The demand systems approach uses the Almost Ideal Demand ...

Sustainable Eating Futures: A Case Study in Saudi Arabia
(2022-10-25)
Food systems are central to human societies. Developing sustainable, nutritious, and healthy food systems will be crucial to accomplishing sustainable development goals. The multifarious politics underlying food production, distributions as well as consumption are often ignored. The present paper analyses different factors affecting food consumption in the local population of Saudi Arabia and relates them to the supply chain. Different futuristic scenarios are discussed to develop sustainable food consumption practices ...

The First Informationexplosion
(2022-06-20)
The paper places punch card technology in the context of the office machine industry in Germany and discusses the exciting relationship between the two competitors on the market for punch card technology, Dehomag and Powers, in Germany. The question is whether the leading role of the United States in the use of office machines frequently cited by Anglo-American authors really applies. How punch card technology in Germany has advanced from its beginnings is discussed under the heading of rationalisation strategies. ...

Nominal Science without Data
(2022-09-28)
Expanding upon literature on early digital computers, this paper shows the role mathematicians have undertaken in founding the academic fields of Game Theory and Operations Research, and details how they were supported by the mathematics departments of military agencies in branches of the US Armed Services. This paper claims that application is only decoration. Other than astronomy, physics and engineering, where experiments generate data analysed with the aid of models and appropriate software on computers, Game ...

Constant Temperature Approach for the Assessment of Injection Molding Parameter Influence on the Fatigue Behavior of Short Glass Fiber Reinforced Polyamide 6
(2021-05-13)
Short glass fiber reinforced plastics (SGFRP) offer superior mechanical properties compared to polymers, while still also enabling almost unlimited geometric variations of components at large-scale production. PA6-GF30 represents one of the most used SGFRP for series components, but the impact of injection molding process parameters on the fatigue properties is still insufficiently investigated. In this study, various injection molding parameter configurations were investigated on PA6-GF30. To take the significant ...

Natural Resources, Raw Materials, and Extractivism: The Dark Side of Sustainability
(2022)
• Extractivism is the dark side of sustainability
• raw materials and primary commodities are the backbones of the global economy
• extraction and export of raw materials lead to Extractivism understood as a development model
• Extractivism is persistent, prone to crisis, and affects domestic and international constellations

Finite Element Simulations for the Design of Therapeutic Approaches for Retinal Diseases
(2022)
The retinal disease age-related macular degeneration is the most common cause of vision loss in industrialized countries. In this thesis, motivated by the drug (antibody) treatment of this disease, we designed long-term three dimensional Finite Element simulations of the drug distribution in the healthy human eye. The underlying model consists of a time-dependent convection-diffusion equation coupled to a stationary Darcy equation describing the flow of the aqueous humor through the vitreous medium. We replaced the ...

Thermal Properties of Plasticized Cellulose Acetate and Its β-Relaxation Phenomenon
(2021-04-21)
Cellulose acetate (CA), an organic ester, is a biobased polymer which exhibits good mechanical properties (e.g., high Young’s modulus and tensile strength). In recent decades, there has been significant work done to verify the thermal and thermomechanical behaviors of raw and plasticized cellulose acetate. In this study, the thermomechanical properties of plasticized cellulose acetate—especially its β-relaxation and activation energy—were investigated. The general thermal behavior was analyzed and compared with ...

Conputational Linguistic Approach to Implicit Sentiment Analysis: Politeness and Sentiment Interaction
(2022)
Sentiment analysis is a hot topic in many research fields such as linguistics, computer science and marketing. With the development of technology, machines can reach very high performance on explicit sentiment analysis both sentence-level and aspect-level. The role of computational linguists has also changed from handcrafting scoring rules to guide training data annotation as the algorithms are developed from rule-based scoring to deep learning models that can extract language features themselves. Moreover, research ...
