The idea of this paper is to introduce into the algebra of automata introduced in [4] probabilities on the actions. This permits a compositional description of probabilistic processes, in particular of Markov chains, and for this reason we call the automata we introduce Markov automata. We define a Markov automaton with a given set A of “signals on the left interface”, and set B of “signals on ...

In this paper we extend the predicate logic introduced in [BRS02] in order to deal with Semi-Markov Processes. We prove that with respect to qualitative probabilistic properties, model checking is decidable for this logic applied to Semi-Markov Processes. Furthermore we apply our logic to Probabilistic Timed Automata considering classical and urgent semantics, and considering also predicates on...

In the southeastern US, Atlanta is always focus of attention, despite rapid expansion small and medium-sized cities (SMSCs) in region. Clearly, larger have more people, resulting loss during disasters. However, SMSCs also face natural calamities must be made robust sustainable. Keeping this mind, study chooses to on ten Alabama (Population > 40,000) which encountered at least a 6% increase p...

Abstract As one of the largest super-saline lakes in world, Lake Urmia northwestern Iran has been facing severe drying recent years. Drought and rapid expansion agricultural activities are considered to be main driving factors shrinking lake. To address this problem, an analysis spatiotemporal dynamics land use/land cover (LULC) is important. This research implemented a multi-source satellite i...

Climate and land-use change are important factors in the hydrological process. Climatic anthropic changes have played a crucial role surface runoff changes. The objective of this research was to apply future climate predict Pak Phanang River Basin. Cellular Automata (CA)-Markov model used change, while data from 2025 2085 under RPC2.6, RPC4.5, RPC8.5 were generated using MarkSim model. Addition...

Land use and land cover (LULC) change is one of the clearest representations global environmental phenomenon at various spatial temporal scales. Chile worldwide recognized to have areas dedicated non-native forest plantations that specifically in coastal range show high economic deterioration, questioning sustainability forestry industry. Currently, there are no studies reveal real effects LULC...

Considering urbanization can lead to irreversible land transformations, it is crucial provide city managers, environmental resources and even people with accurate predicting use/land cover (LULC) accomplish sustainable development goals. Although many methods have been used predict (LULC), few studies compared them. Therefore, by analyzing the results of various prediction models and, consequen...
