Impervious surface is an artificial surface that prevents water from seeping into the ground. Impervious surface is not only an indicator of the level of urbanization but also a key indicator of the quality of the urban environment. This article presents the results of an impervious surface classification in Ho Chi Minh City area from multi-temporal Landsat image data.

This purpose of this work was to investigate the patient radiation doses and image quality of a Philips/Agfa computed radiographic (CR) system and a Philips indirect-capture digital radiographic (DR) system in a paediatric setting. A CDRAD digital radiographic contrast-detail phantom was used to assess radiographic image quality. Perspex slabs of three different thicknesses (6, 11 and 16 cm) were used to simulate paediatric patients of three arbitrary ages.

The overall aim of this study is to determine the most effective way to reduce the radiation dose to the breast during non-breast related CT scans, whilst still maintaining a suitable image quality. This study will attempt to compare the doses and noise of various protocols that can be used for dose reduction, including tube current modulation, bismuth breast shields and manual reduction of tube current.

To evaluate the effect of the single energy metal artifact reduction (SEMAR) algorithm with a multide‑ tector CT (MDCT) for knee tumor prostheses. Methods: First, a phantom of knee tumor prosthesis underwent a MDCT scan. The raw data was reconstructed by iterative reconstruction (IR) alone and IR plus SEMAR. The mean value of the CT number and the image noise were measured around the prosthesis at the stem level and articular level.

It has obtained great results in theory as well as practical applications. However, the accuracy of identification is still limited, especially in the case of low-quality input images. In this article, we propose an efficient method to recognize information fields for identification in ID card using Convolutional Neural Network (CNN) and Long Short-Term Memory networks (LSTM).

The experiment was conducted to investigate the embryonic development of discus (Symphysodon aequifasiatus) and determine the time required for major egg developmental stages and hatching. Regular observations were made using optical microscope and the images were recorded using a digital camera attached to the microscope. Important water quality parameters were kept optimal for the hatching of discus eggs.

When a satellite is in orbit, micro vibration generated by its actuators (such as reaction wheels, deployable mechanisms, etc.) will affect the imaging quality of the camera. Viscoelastic materials are utilized as passive isolators to reduce these micro vibrations due to their simple construction and excellent energy dissipation capacity.

This research empirically attempted to assess the effect of brand familiarity and perceived service quality on brand image as well as to explore the position of brand image on student satisfaction in addressing previous efforts' mixed outcomes and bridging the gaps in the private higher education area. The data were collected from students of Jadara university in Jordan. PLS-SEM methods were used to test hypothesized relationships on a sample of 112 students.

The Co nanowire arrays were fabricated by electrodeposition method by using the porous polycarbonate template. Study on crystallographic structure, micro structure, and the element composition confirmed the quality of the fabricated Co nanowires. SEM image shows the wires with an average diameter of 200 nm and the average length of 9 m. The magnetic properties, measured at room temperature using vibrating sample magnetometry (VSM), displays that the nanowires have anisotropic property.

The demand of transmission of images and video is increasing quickly recently and researchers are trying to invest good solutions to improve the quality of these over wireless networks. There are still challenges due to the different characteristics and quality of images between wired and wireless channels. An important issue is congestion control to ensure network stability and achieve a reasonably fair distribution of the network resources among the users.

In the past three decades, due to significant liberalization and privatization the entire telecommunications industry has become a dynamic service industry subject to increasing competition with huge growth potential. (Graack, 1996). In recent years, in some Asian countries the number of mobile subscribers even passed the number of fixed-line subscribers (Fink, Matto, & Rathindran, 2003). Hence, the strategic behavior of telecommunications companies has attracted so much attention in recent years, both in the academic literature and in the popular press.
