Lung cancer is a dangerous non-communicable disease attacking both women and men every year it causes thousands of deaths worldwide. Accurate lung nodule segmentation in computed tomography (CT) images can help detect early. Since there are different locations indistinguishable shapes nodules CT images, the accuracy existing automated methods still needs further enhancements. In an attempt towa...

this study examines the transport of seventeen heavy metals between the isipingo estuary andthe adjacent sea. results demonstrate variability of fluxes in terms of prevalence, concentration and seasonality.summer neap and spring tides had approximately twice the number of heavy metals compared to winter andspring seasons. spring and winter seasons yielded higher concentrations and a greater num...

the net analyte signal standard addition method was used for simultaneous spectrophotometric determination of sertraline and fluoxetine in pharmaceutical preparations. the method combines the advantages of the standard addition method with the net analyte signal concept to enable the extraction of information about an analyte from the spectra of multi-component mixtures. this method uses full s...

A blur detection problem which aims to separate the blurred and clear regions of an image is widely used in many important computer vision tasks such object detection, semantic segmentation, face recognition, attracting increasing attention from researchers industry recent years. To improve quality separation, have spent enormous efforts on extracting features various scales images. However, ma...

The basic concepts of the Petri Net Baukastenn are introduced. The Petri Net Baukastenn is a Petri net technology and provides Petri net techniques. The Petri Net Baukastenn is consists of the Common Base and three diierent views, the Application Developer View, the Tool Developer View, and the Expert View. The main focus is to support the application developer and the tool developer as well as...

The paper presents a speech coding algorithm for operation at 11 025 samples/s. The coder provides improved speech quality and compatibility with the MS-Windows multimedia environment. The coding algorithm has been developed by adapting the ITU G729 and enhancing it with some recent developments in the medium band coding. The coder operates over a band of frequencies ranging from 20 to 5400 Hz ...

Lasso proved to be an extremely successful technique for simultaneous estimation and variable selection. However lasso has two major drawbacks. First, it does not capture any grouping effect and secondly in some situations lasso solutions are inconsistent. To overcome inconsistency recently adaptive lasso was proposed where adaptive weights are used for penalizing different coefficients. Adapti...
