Multifactor Violator Model. Condition-factors and Resource-factors

open access: yesEuropean Journal of Electrical Engineering and Computer Science, 2020
Attack scenarios with limitations were investigated. Resource-factors and condition-factors were set as two types of limitations. Resource-factors are spent at each step of attack and can be replenished completely or partially if a given attack step was successful. A situation, where successful completion of current step with one or more preceding ones

Water level influences on body condition of Geophagus brasiliensis (Perciformes: Cichlidae) in a Brazilian oligotrophic reservoir

open access: yesNeotropical Ichthyology
Effects of water level fluctuations on body condition of Geophagus brasiliensis were studied in a 30 km² Brazilian oligotrophic reservoir. Physiological condition (K) and gonadosomatic index (GSI) were compared according to water level (low and high ...
