Paleomagnetic data provide one of the few probes available to interrogate early evolution of the core. Here we apply this probe by examining the latitudinal dependence of paleosecular variation (PSV) data derived from high-quality paleomagnetic data collected from Proterozoic and Neoarchean rocks. These data define a Neoarchean geomagnetic field that was more dipolar than that during Proterozoi...

Hydrologic and ecologic studies in mountainous terrain are sensitive to the temporal and spatial distribution of precipitation. In this study a geostatistical model, Auto-Searched Orographic and Atmospheric Effects Detrended Kriging (ASOADeK), is introduced to map mountain precipitation using only precipitation gauge data. The ASOADeK model considers both precipitation spatial covariance and or...

: Distributed generation (DG) sources are becoming more important in electrical networks due to the increase of energy demands. However, DG can have a profound effect on network power loss. Hence, optimal placement and size DGs extremely important. This study presents backtracking search algorithm (BSA) based multiple within distribution systems so reduce The BSA is new heuristic algorithm. Two...

A sampling plan named as Multiple Dependent State Repetitive Group Sampling (MDSRGS) is introduced for a time-truncated life test given that the underlying distribution of product's lifetime Inverse Power Lomax (IPLD). The proposed developed with help two already plans (MDS and RGS). two-point approach OC function known producer's risk customer's used to determine parameters plan. An optimizati...
