Abstract

Abstract: The satellite image classification system intends to differentiate between the objects being present in the image. It is highly challenging because the coverage area of the satellite is large such that the objects appear so small. This makes the process of object differentiation complex. Additionally, the classification accuracy is an important factor, which the classification system must pass through. This work presents a satellite image classification system which can classify between the vegetation, soil and water bodies, etc. Current research work is in the development of a hybrid classification technique for satellite images. High-resolution satellite images that we deal with using SVM and low accuracy through the use of k-means. It is necessary to provide accuracy and speed of satellite images and obtain this through the modulation method suggested through the integration of these technicians, where technology can classify all satellite images .We note that the proposed system is able to classify any satellite image by highlighting each region and what indicates that area and what percentage when applying the proposed system of classification whether the satellite images are based on high accuracy or low accuracy, where the system also shows the time taken to classify each satellite image. We note that the time does not exceed 30 seconds for the number of images used within our database

Abstract

Abstract: There are heterogeneity and increase in the percentage of ionization with solar explosions, where the so-called sudden ion disturbance (SID), Which can be measured by the so-called very low frequencies (VLF), where used in this study to calculate the extent change of the signals amplitude between the receiver built in our station (ISIO) and the transmitters from different regions of the world comparing that with another receiver 4000 kilometers north, when location at southern France (A11٣), which receives the signals from the same transmitters, which we received the same signals and the timing of each solar event. Five events received by our station from the period (2017-6-3) to the period (2017-9-10). These events are compared with a set of events that recorded at different periods .The results showed that the signals amplitude in all events is much higher than the signal amplitude received from the French station. This variation in amplitude is due to the heterogeneity of the receiving location at our station, which also means that the ionosphere at the top of this region, which is considered to be part of the subtropical regions, is different from those near the polar gap.

Abstract

Abstract: Clouds are collections of tiny particles of water and/or ice that are large enough to be visible. The two required ingredients for the formation of cloud are water vapor and aerosols. The spontaneous growth of Cloud Condensation Nuclei (CCN) into cloud droplets under supersaturated water vapor conditions is described by classic Köhler theory. The aim of this work is to model Köhler theory and investigate effects of mass, solubility, and composition of the CCN in the formation and growth of cloud droplets. Sodium Chloride (NaCl) and Ammonium Sulfate ((NH4)2SO4) were used as a solute material. The results showed that both mass and solute material affect the nucleation of cloud droplet. Increasing mass of solute would increase the critical radius and decrease the supersaturation required for activating the droplet. It was found that the use of NaCl produce critical radius larger than that of (NH4)2SO4 and the required supersaturation for NaCl solute is lower than that of (NH4)2SO4 solute. This is due the fact that NaCl has lower molecular weight than (NH4)2SO4. The results also indicate that cloud temperature has minor effect on the cloud droplet activation. The model can be used to investigate more suitable solute materials to determine which is best for cloud seeding projects.

Abstract

Abstract: The atmosphere aerosols play an important role in the physical processes occur in the atmosphere. Such as absorption and scattering of solar radiation and formation of cloud and precipitation. Consequently, aerosols affect the radiation balance and water balance of atmosphere. Therefore, the study of optical properties of aerosol is very important in many applications such as modeling of solar radiation, cloud modeling and climate modeling. The aim of this research is to investigate the aerosols optical properties using the Optical Properties Aerosol and Cloud (OPAC) software package. Three types of aerosols were considered, namely continental, desert, and urban aerosols. The results indicated that the optical properties of aerosols (extinction, scattering, absorption coefficients; single scattering albedo; asymmetric parameter, and optical depth) in general decreases with increasing wavelengths but they decrease sharply at shorter wavelength and gradually at longer wavelengths. In addition, the effect of atmospheric windows is evident in the 5-10 μm range of the spectrum. The results also suggested that desert aerosols are the most effective type followed by urban and continental polluted aerosols. Change in relative humidity can affect the optical properties of the continental and urban aerosols while the desert aerosols are almost unaffected by the change of relative humidity.

Abstract

Abstract: Linear and nonlinear optical properties of Polyvinyl Alcohol thin film doped with cadmium telluride nanoparticles have been investigated experimentally. CdTe nanoparticles were produced in distilled water by pulsed laser ablation method under Nd-YAG laser at (100 mJ, 1064nm, 10ns, 6Hz, and 100 laser shots). AFM images were used to study the nanoparticles after ablation. XRD pattern and UV– Vis spectroscopy data were used to extract the structure and optical properties of films. Z-scan technique was employed to characterize of nonlinear optical properties of the films. The results of close-aperture zscan data suggested that PVA/CdTe nanocomposite film included a nonlinear refractive index with a negative sign, meaning the occur of self-defocusing phenomenon. While, open-aperture z-scan data clearly suggested two-photon absorption as the dominant nonlinear absorption mechanism. The nonlinear property of PVA film was found increasing and strongly after added nanoparticles in them.
