Land Degradation, Small-Scale Farms’ Development, and Migratory Flows in Chiapas
(kassel university press, 2013)
This research evaluates the impacts of land degradation on rural development and migration, using a comparative-analysis platform and quantitative and qualitative approaches, based on data from empirical investigations in six rural communities of Tapachula, Chiapas. The results show that deforestation, heavy rains and extreme weather events are the main determinants of land degradation, and that land degradation, smallholder farms’ income and outmigration are highly correlated. In addition, they portray a new migration ...

Numerische Beanspruchungsanalyse von Rissen und Berechnung von Risspfaden mittels wegunabhängiger Erhaltungsintegrale
(kassel university press, 2017)
Die Bewertung technischer Strukturen mit Rissen stellt einen wichtigen Aspekt zu deren sicherem und wirtschaftlichem Betrieb dar. Zur Bewertung von Rissen sind bruchmechanische Konzepte notwendig, die den Defekt in der Beanspruchungsanalyse der Struktur berücksichtigen. Die Beanspruchungsanalyse an einem beliebigen Randwertproblem mit Riss erfolgt i.A. auf Basis numerisch berechneter Spannungs- und Verschiebungsfelder. Als besonders effizient haben sich hier wegunabhängige Erhaltungsintegrale erweisen, bei deren ...

Tratamiento térmico de biosólidos para aplicaciones energéticas. Pirólisis y conversión de sus alquitranes.
(kassel university press, 2019)
Se estudia la pirólisis de biosólidos de plantas de tratamiento de aguas residuales urbanas (PTAR) y la conversión de los alquitranes presentes en la fase volátil. Se usan biosólidos de la PTAR El Salitre en Bogotá, D.C., Colombia, a los que se realiza caracterización de combustibles. Pirólisis con tasas bajas de calentamiento (3 K/min a 10 K/min) se realiza en una retorta de laboratorio siguiendo el estándar ISO 647 (hasta 520 °C) y en un equipo de termogravimetría (TGA) (hasta 950 °C). La fracción gaseosa se analiza ...

Run-time Reconfigurable Constant Multiplication on Field Programmable Gate Arrays
(kassel university press, 2017)
This book addresses the question how run-time reconfigurable constant multipliers (RCMs) can be efficiently implemented on field programmable gate arrays (FPGAs). RCMs calculate the multiplication of an input number by one out of several constants which can be selected during run-time. This is important as constant multiplication is an essential operation in digital signalprocessing (DSP) applications. The evaluation of RCMs is done by considering reconfiguration using reconfigurable look-up tables (LUTs),reconfiguration ...

Discrete time sliding mode control strategies applied to a multiphase brushless DC machine
(kassel university press, 2017)
Nowadays, environmental issues motivates the replacement of mechanical, hydraulic and pneumatic system by electrical system in the transport sector aiming to reduce emissions generated by burning of fossil fuels in vehicles. The electrical system must ensure high electrical efficiency and should not exceed the weight of the substituted components. To attend these high performance requirements a fault-tolerant multiphase brushless DC machine was chosen for this research.The present work introduces a six-phase 600W ...

India’s Macroeconomic Policy Regime and Challenges of Employment
(kassel university press, 2018)
On would hardly quibble with the view that eradication of poverty and promotion of decent work depends on sustained and inclusive economic growth, and not simply high rates of growth per se. This of course requires necessary intervention on several fronts, in particular adequate macroeconomic space for national governments while being open to equitable multilateral trading systems. Investments in physical and social infrastructure with due emphasis on rural areas, necessary structural reforms, appropriate fiscal and ...

Self-help groups for India’s financial inclusion
(kassel university press, 2017)
Ensuring accessibility to credit to the poor self-employed households is a critical concern for many developing nations. Self-help groups (SHG) formed by women in the developing countries help them to access financial intermediaries and access credit for various income-generating activities. In case of India, SHGs are formed either through state-assisted SHG-Bank Linkage Programme (SBLP) or through private initiatives of micro finance institutions (MFIs) or NGOs. Under the former, the groups access formal banking ...

Microfinance through Women Self-Help Groups (SHGs) for Grass-root level Empowerment: An Empirical study of Varanasi, Uttar Pradesh, India
(kassel university press, 2016)
Microfinance, as a concept, involves providing financial services, particularly small credit, fund transfer, and insurance to the unemployed, low-income group, and those who do not have easy access to the banking system. It has emerged as an active agent of financial inclusion, ensuring economic, and social upliftment of the unprivileged. Microfinance is being operated through two channels Self-help Group-Bank Linkage Programme (SBLP) and Micro-finance Institutions (MFIs). The special characteristic of SBLP is its ...

Numerische Modellierung von Fluid-Struktur-Wechselwirkungen an wellenbeaufschlagten Strukturen
(kassel university press, 2014)
Die vorliegende Arbeit behandelt die numerische Modellierung von Fluid-Struktur-Wechselwirkung (FSI) an wellenbeaufschlagten Strukturen mittels eines partitionierten Block-Gauß-Seidel-Lösungsverfahrens. Die Berechnung der Teilpartitionen der multiregionalen bzw. multiphysikalischen Berechnungsfelder basiert dabei auf der numerischen Finite-Volumen-Methode (FVM). Das Hauptaugenmerk der Arbeit liegt auf der Entwicklung eines Fluid-Struktur-Wechselwirkungs-Algorithmus zur Untersuchung von dämpfungsbegünstigten Eigenschaften ...
