abstract background: despite the scientific and medical advances for management of complicated health issues, the current maternity care setting has increased risks for healthy women and their babies. the aim of this study was to conduct an overview of published systematic reviews on the interventions used most commonly for management of normal labor and delivery in the first stage of labor. ma...

the present research is classified as an applied one employing a descriptive survey design to describe the status quo of the factors affecting customers’ satisfaction with the e-service centers of iran’s police, known as 10 + police centers. the research population involves all the costumers of the 10+ police centers, among which 420 individuals were chosen through simple random sampling techni...

In this paper, we propose a novel scheme for image compression by the curvelet transform. Curve functions are effective in representing functions that have discontinuities along straight lines. Normal wavelet transforms fail to represent such functions effectively. Modification of the traditional JPEG method based on region-of-interest coding is achieved and used curvelet transform. The modific...

Over the years, building envelope has evolved from a protective barrier element to complex filter system capable of optimizing interactions between external and internal environments. An efficient reacts flexibly variable conditions, minimizing heat losses in winter season. Therefore, insulating materials play fundamental role building’s thermal performance. In this scenario, Additive Manufactu...

Block-box structures today are widely used in construction. Their main features mobility, lightness and the possibility of assembling block-boxes for any technological purpose. Block-boxes arrangement oil gas fields, settlements cities where it is necessary to carry out construction a short period time or there no industrial infrastructure. When designing, often take into account special loads ...

Recently, the complementary behavior of restarted GMRES has been studied. We observed that successive cycles of restarted block BGMRES (BGMRES(m,s)) can also complement one another harmoniously in reducing the iterative residual. In the present paper, this characterization of BGMRES(m,s) is exploited to form a hybrid block iterative scheme. In particular, a product hybrid block GMRES algorithm ...

Passive forensics analysis aims to find out how multimedia data is acquired and processed without relying on pre-embedded or preregistered information. Since most existing compression schemes for digital images are based on block processing, one of the fundamental steps for subsequent forensics analysis is to detect the presence of block artifacts and estimate the block size for a given image. ...
