Abstract The possible occurrence of major space weather events, such as large solar flares within one hundred years, is studied anticipating their effects on our social facilities. However, the continuous soft X-ray (SXR) observation by Geostationary Operational Environmental Satellites (GOES) started in 1975, and period data collection less than 50 years. On other hand, ground-based sunspot ob...

As one of the most promising Distributed Generation (DG) sources, wind power technology has been widely developed in recent years. Doubly fed induction generator (DFIG) is currently employed as one of the most common topologies for wind turbine generators (WTGs). This generator operates as a synchronous/asynchronous hybrid generators. Therefore, it is necessary to power engineers find understan...

This paper presents a complete derivation and implementation of the Arbitrary Lagrangian Eulerian (ALE) formulation for the simulation of nonlinear static and dynamic problems in solid mechanics. While most of the previous work done on ALE for dynamic applications was mainly based on operator split and explicit calculations, this work derives the quasi-static and dynamic ALE equations in its si...

Salinity of soil and water is the most important agricultural hazard in arid and semi-aridregions. In saline soils, yield production directly influences by soluble salts in the root zone aswell as by shallow water table depth. The first step for reclamation of such soils is reducingsalinity to optimum level by leaching. The objective of this study was to develop a practicalmodel to estimate wat...

Service-oriented architecture facilitates the running time of interactions by using business integration on the networks. Currently, web services are considered as the best option to provide Internet services. Due to an increasing number of Web users and the complexity of users’ queries, simple and atomic services are not able to meet the needs of users; and to provide complex services, it requ...

Background: Hepatitis delta virus (HDV) is a subviral human pathogen that exploits host RNA editing activity to produce two essential forms of the sole viral protein, hepatitis delta antigen (HDAg). Editing at the amber/W site of HDV antigenomic RNA leads to the production of the large form (L-HDAg), which is required for RNA packaging. Methods: In this study, PCR-based site-directed mutagen...

A 17-year-old female presented with dyspnea, chest pain, and a very large cyst occupying the entire right hemithorax Figure 1(A, B). The patient is under full cyst extending to membrane Figure 2 (A, B).

In this paper, we extend and generalize some recent results on the strong laws of large numbers (SLLN) for pairwise independent random variables [3]. No assumption is made concerning the existence of independence among the random variables (henceforth r.v.’s). Also Chandra’s result on Cesàro uniformly integrable r.v.’s is extended.
