Generally, drainage basin maps are a very complicated process especially for flat area. These maps consider being very important issues that can be used in water resources management, agriculture, civil construction and civil defense. For this reason these maps consider to be vital source of information. There are many kinds of methods and algorith...

The selection of an appropriate dispatch strategy is considered as a major concern when designing hybrid energy system (HES) since it has large effects on the stability, reliability, environmental and economic performance of the system. The cycle charging (CC) strategy is a default dispatch strategy in HOMER software. However, the main drawback of...

In this study, The size of silica nanoparticles has a substantial impact on preparation elements such pH, magnetic field intensity, and exposure time. These parameters can be changed in a systematic manner to reduce or increase particle size. A dynamic light scattering test was also used to investigate the effect of a magnetic field on the particle...

Hybrid energy systems (HESs) consisting of both conventional and renewable energy sources can help to drastically reduce fossil fuel utilization and greenhouse gas emissions. The optimal design of HESs requires a suitable control strategy to realize the design, technical, economic , and environmental objectives. The aim of this study is to investig...

In this paper, a low-cost reverse-gliding arc three-dimensional reactor with local materials and a homemade voltage source was proposed. This system works by pumping out argon gas while mixing in atmospheric air. The spectral properties of the resulting arc were investigated, as well as the calculation of electron temperature and density. The proce...

A B S T R A C T In this theoretical study, we predict the (111), (001), and (110) Mn3P compounds with a DO3-Type-structure. We first calculated the stability, and surface effects on the pure terminations of Mn3P (111), (001), and (110) surfaces using first-principle computations. Pure (111), (110), as well as the Mn2-(001) terminations, lose their...

Digital images used in the field of ophthalmology are among the most important methods for automatic detection of certain eye diseases. These processes include image enhancement as a primary step to assist optometrists in identifying diseases. Therefore, many algorithms and methods have been developed for the enhancement of retinal fundus images, w...

Upconversion materials, which have the ability to transfer light's intensity, have reliable implementations on instruments from which they can synthesize light spectrum to better efficiency fulfillment. It has become useful to isolate the transformed nanomaterials with low clarity in a medium with a low optical attenuation coefficient; this step he...

Image segmentation, a technology that divides images into parts, is an important technique in image processing, and is used in various disciplines, such as remote sensing, medical imaging, and industrial fields. Several methods and known algorithms are used for image segmentation. This paper proposes a new algorithm for image segmentation that is b...

In this study, the radiological efficacy of selected samples of a hole produced by a rocket dropped during military operations in the second Gulf battle was measured. Since the fall of the rocket in 1991 on district of Tuwayrej, Karbala at central Iraq until this moment, there have been many miscarriages in women as well as cases of congenital malf...

The elemental ingredients of deciduous specimens have been analyzed using Laser incited breakdown spectroscopy method (LIBS). Many elements have been discovered in the deciduous teeth samples, the important once are Ca, P, Mg, C and Na. The test of caries part of teeth samples contained less amount of Ca, P, Na, and higher amount of C and Mg than i...

Drawing blood and injecting drugs are common medical procedures, for which accurate identification of veins is needed to avoid causing unnecessary pain. In this paper, we propose a low-cost system for the detection of veins. The system emits near-infrared radiation from four light-emitting diodes (LEDs), with a charge-coupled device (CCD) camera lo...

With the great development in medical image processing that has been achieved recently, it has become an integral part of diagnostic tools and treatment tools attached to medical imaging devices such as the magnetic resonance imaging (MRI) device. In this paper, we propose an algorithm to extract tumours from MRI images using the MATLAB environment...

Nowadays, various cosmetic blushers from different brands and regions being sold in Iraqi markets. The main aim of this paper is to identify its usage suitability by which too many Chinese brands forms the majority of these blushers. X-ray fluorescence and laser induced breakdown spectroscopy techniques has been applied to calculate the concentrati...

Enhanced Thematic Mapper Plus (ETM+) onboard the Landsat-7 remotely sensor satellite was launched on 15 April 1999. On May 31, 2003, image acquisition via the ETM+ was greatly impacted by the failure of the system's Scan Line Corrector (SLC). Consequently, the ETM+ has lost approximately 22% of the data due to the increased scan gap. In this work,...
