Background: PIn air quality studies, it is very often to have missing data due reasons such as machine failure or human error. The approach used in dealing with can affect the results of analysis. main aim this study was review types mechanism, imputation methods, application some them PM10 and O3 Tabriz, compare their efficiency. Methods: Methods mean, EM algorithm, regression, classification ...

Genetically modified plants (GMPs) may soon be cultivated commercially in several member countries of the European Union (EU). According to EU Directive 2001/18/EC, post-market monitoring (PMM) for commercial GMP cultivation must be implemented, in order to detect and prevent adverse effects on human health and the environment. However, no general PMM strategies for GMP cultivation have been es...

Pacific Meridional Mode (PMM) is known to be significantly correlated with tropical cyclone (TC) genesis over the western North (WNP), while stability of their relationship remains unknown. Here we found that nonstationary, which depends on phase Decadal Oscillation (PDO). During PDO warm phases, PMM-emanated cyclonic circulation and ascending motion can propagate entire WNP due enhanced backgr...

This paper proposes an innovative Pipeline-based Maximalsized Matching scheduling approach, called PMM, for input-buffered switches. It dramatically relaxes the timing constraint for arbitration with a maximal matching scheme. In the PMM approach, arbitration operates in a pipelined manner, where K subschedulers are used. Each subscheduler is allowed to take more than one time slot for its matc...

In this article we use the recently developed perturbed matrix method (PMM) to investigate the effect of conformational fluctuations on the electronic properties of heme in Myoglobin. This widely studied biomolecule has been chosen as a benchmark for evaluating the accuracy of PMM in a large and complex system. Using a long, 80-ns, molecular dynamics simulation and unperturbed Configuration Int...

In this paper, the Polynomial Matrix Multiplication (PMM) of polynomial vectors and/or polynomial matrices have been introduced. This method provides an improvement of the fast convolution technique to multiple inputs multiple output systems (MIMO). It is devoted to the hardware implementation of PMM. The hardware implementation of this method is achieved via partly systolic, field programmable...

Extratropical atmospheric variability can impact tropical climate in the Pacific sector via the Pacific Meridional Modes (PMMs). The South PMM (SPMM) has a larger equatorial signature than the North PMM (NPMM) for the same amount of extratropical variability. Here we explain this interhemispheric asymmetry using an atmospheric general circulationmodel coupled to a slab ocean model. By imposing ...

In modern pervasive dynamic and eternal systems, software must be able to self-organize its structure and self-adapt its behavior to enhance its resilience and provide the desired quality of service. In this high-dynamic and unpredictable scenario, flexible and reconfigurable monitoring infrastructures become key instruments to verify at runtime functional and non-functional properties. In this...

The Object and Action Model (OAM) is well-known as an adequate paradigm to build fault-tolerant configurable distributed applications. The reconfiguration of an application depends on the construction of a consistent global snapshot of its global state. An atomic action that reads the states of all objects of the application is a simple and straightforward way to obtain such global snapshot, bu...
