Abstract

Uniaxial compressive strength (UCS) and Modulus of Elasticity or Young’s Modulus (E) used in most of engineering projects in rock mechanics, are the most important mechanical parameters of rocks. The calculation of these parameters needs most cost, time and effort. There are indirect methods to estimate the (UCS) and (E) such as Schmidt Hammer, also known as a rebound number (RL), this indirect method is easily and quickly applicable in laboratory and in field and it is considered as a non-destructive method for evaluation of surface hardness. The aim of this paper is to establish a correlation between UCS, E and Schmidt Hammer rebound value and it has been carried out on forty-nine specimens of different sedimentary rock types that belong to three different formations in Kurdistan Region, Iraq (Pila Spi Formation, Fatha Formation “Lower Fars Formation” and Tanjero Formation) with ages (Middle-Late Eocene, Middle Miocene and Campaman-Maastrichtian) respectively. The samples were prepared as cuboids of size 5x5x10 cm. A new correlation with high accuracy level for prediction of (UCS) and (E) from Schmidt hammer of some sedimentary rocks is proposed for the first time in Kurdistan Region-Iraq.

Abstract

The main idea of image encryption is to ensure secure transmitting it in the open network by transforming the image to not understandable form so that unauthorized person cannot decrypt and see it. This paper introduces a hybrid image encryption method based on the details of the Mandelbrot set fractals and the private XOR operation. Due to the random nature of fractal images, they can be used as a strong key for encryption. The strength of the key caused by using three random parameters as a secret keys (two of them are the zooming position values x & y, and the third is number of zooming times form that position) used to create the fractal-based key image, and they can generate large number of random fractal images. To make the secret image more secure, the original image is encrypted by applying XOR bit operation on each adjacent pixels of the image. At last the resulted image is combined with the previously obtained fractal-based key image using a predefined private XOR table in a complex order. To evaluate the performance of the system, the correlation coefficients, visual test using histogram analysis and different secret keys were used. All tested results proved that the proposed method is promising and effective to be used in image encryption fields.

Abstract

The reuse of existing Wireless Fidelity (Wi-Fi) setup for indoor localization using Wi-Fi Received Signal Strength Indicator (RSSI) is nowadays an active research domain. Over the period these Wi-Fi setups show degradation in performance owing to signal attenuation caused by multipath, along with environmental changes adversely affecting the functional efficiency. To optimize the indoor localization precision in the presence of the issues as mentioned earlier, I propose Spearman's Rank based Correlation Coefficient approach which finds the minimum distances and provides these distances to the original K-Nearest-Neighbor (k-NN) classifier which uses Euclidean distance. After the complete indoor Wi-Fi environment is simulated in Matrix Laboratory (Mat-lab) tool, the results so obtained are promising and on the higher side as compare to the original k-NN classifier performance. In case of distribution of cumulative errors the proposed method achieved low amount of localized errors of 2.7m for 80% tested samples. And as for shadow fading increase in value of
