Verteilungswirkungen anreizorientierter Sozialpolitik : das deutsche Rentenversicherungs- und Steuersystem in der Perspektive dynamischer Lebenszyklusmodelle

Grub, Martin - 2005

Drei große Reformenpakete und eine Reihe kleinerer Begleitmaßnahmen prägen das renten¬politische Erbe der rot-grünen Bundesregierung. Einerseits greifen sie Trends in der Reformpolitik seit Beginn der 90er Jahre auf. So verstärkt die Rentenstrukturreform 2001 beispielsweise die...

Energy security, uncertainty and energy resource use options in Ethiopia : A sector modelling approach

Guta, Dawit; Börner, Jan - In: International Journal of Energy Sector Management 11 (2017) 1, pp. 91-117

Purpose Ethiopia’s energy sector faces critical challenges to meeting steadily increasing energy demand given limited infrastructure, heavy reliance on hydroelectric power and underdevelopment of alternative energy resources. The purpose of this paper was to identify optimal least cost...

Geometric arrangement and operation mode adjustment in low-enthalpy geothermal borehole fields for heating

Beck, Markus; Bayer, Peter; de Paly, Michael; … - In: Energy 49 (2013) C, pp. 434-443

. This paper introduces a new combined optimization approach, which adjusts the BHE positions as well as the individually … changing load profile. The optimization of only the BHE positions without optimizing the individual BHE loads nearly produces … the same improvement of the underground temperature change of approximately 12% as an optimization of the BHE loads …

Sustainable Irrigation Planning with Imprecise Parameters under Fuzzy Environment

Regulwar, D.; Gurav, Jyotiba - In: Water Resources Management 26 (2012) 13, pp. 3871-3892

The present paper proposes a model of Multi Objective Fuzzy Linear Programming (MOFLP) based on Fuzzy Parametric Programming (FPP) to solve the problem of optimal cropping pattern in an irrigation system. It has been found that in order to solve the problem of uncertainty in the planning of...

Comparison of tillage systems according to fuel consumption

Mileusnić, Z.I.; Petrović, D.V.; Đević, M.S. - In: Energy 35 (2010) 1, pp. 221-228

Nowadays, tractor is still the basic power unit in almost all production processes in agriculture, including tillage. The structure of tractor–machinery systems depends on many parameters: seeding system, soil conditions, farm area etc. These relevant parameters are defined in this paper, as...

Market-based congestion management in electric power systems with increased share of natural gas dependent power plants

Pantoš, Miloš - In: Energy 36 (2011) 7, pp. 4244-4255

The paper addresses market-based congestion management (MBCM) in electric power systems taking into account the constraints of the electric power system (EPS) and the natural gas system (NGS). The proposed method is based on the countertrade methodology, where the system operator performs...
