this paper presents a new centralized adaptive method under frequency load shedding. sometimes, after initial frequency drop following severe disturbances, although the system frequency returns to its permissible value, however, the system might become unstable due to voltage problems. in this regard, the paper proposes a new centralized adaptive load shedding method to enhance the voltage stab...

Earthquake research has not yielded promising results because earthquakes have uncertain data parameters, and one of the methods to overcome problem parameters is nonparametric method, namely Multivariate Adaptive Regression Splines (MARS). Sumbawa Island part territory Indonesia in position three active earth plates, so prone earthquake hazards. Therefore, this important do. This study aimed a...

We develop a generalised impulse response function (GIRF) approach to explore the different impacts of aggregate and sectoral shocks within a VAR-GARCH-M model. Using the output of our GIRF analysis, we explore the behaviour of three European countries (Germany, Spain and the UK). We analyse the aggregate and sectoral responses to discriminate among three different hypotheses of business cycle ...

International targets set for reducing the rate of biodiversity loss--the 2010 target--and ensuring environmental stability (Millennium Development Goals) have helped to focus the efforts of the scientific community on providing the data necessary for their implementation. The urgency of these goals, coupled with the increased rate of habitat alteration worldwide, has meant that actions have la...
