The MTS-88. c trainer is a training system targeting students in the microprocessors course. It has a built in single-line assembler allowing the users to enter programs in assembly. It has the problem that long programs cannot be traced and tested efficiently. A simple error may cause all the code to be erased and the system to stop responding. Also, this system lacks the ability to be connected to the PC. The aim of this work is to modify the system to make it possible to be connected to the PC through the parallel port. This gives the capability to download long programs to the system after being developed in the PC. The 8255 Programmable Peripheral Interface available in the teaching system is interfaced to the parallel port and used as

This paper deals with the geomorphological characteristics of a selected study area in Kirkuk province. The cha

It takes a lot of time to classify the banana slices by sweetness level using traditional methods. By assessing the quality of fruits more focus is placed on its sweetness as well as the color since they affect the taste. The reason for sorting banana slices by their sweetness is to estimate the ripeness of bananas using the sweetness and color values of the slices. This classifying system assists in establishing the degree of ripeness of bananas needed for processing and consumption. The purpose of this article is to compare the efficiency of the SVM-linear, SVM-polynomial, and LDA classification of the sweetness of banana slices by their LRV level. The result of the experiment showed that the highest accuracy of 96.66% was achieved by the

Protecting information systems from manipulation and unauthorized access is extremely important. The Diffie-Hellman (DH) protocol is essential for key exchange because it is based on the discrete logarithm problem. Although widely used, this protocol is vulnerable to various attacks like man-in-the-middle, replay, and brute force due to its lack of validation mechanisms for authorized parties. The novel proposed algorithm treats these vulnerabilities and enhances the security of the DH scheme by performing authentication between the two parties based on the complete graph. We have used simple mathematical operations to ease implementation. The proposed work enhances the security of the DH algorithm by using the properties of the complete

The results showed that extracting the veg

In the present work, the detailed calculations of a nuclear collision (deuteron + gold) (D+Au) using the sharp surface density profile as a function of collision impact parameter at center of mass energy (√s_NN = 200 GeV) are presented. The number of nucleons that participate in the collisions, in addition to the differential elastic cross-section, at different energies was calculated. The study of the effect of various energies on the outcome of intranuclear nucleon collisions can be carried out by varying the energy of each collision. Thus, properties of the particles resulting from the collision are observed by the different high energies, √s = 200, 56, 200, 2760, and 5440  GeV . The nuclear overlapping functio

Removing cationic and ionic dyes from aqueous solutions has been studied using mesoporous silica. Cetyltrimethylammonium bromide (CTAB) was used as a template and sodium silicate, a low-cost precursor of silica, was used in the Sol-gel process. The N₂ adsorption–desorption isotherms; TEM, XRD, and SEM were used to analyze the silica particles. The findings demonstrate that mesoporous silica (MPS) particles in the nano range (40-80 nm) have the form of flower particles, with an average pore width of 3.44 nm, a precise surface area of 423.52 m²g-¹, and a pore volume of 0.5677 cm3/g. These particles may effectively adsorb dyes. The Langmuir, Freundlich, and Timken models of adsorption suited the adsorption

The content of fatty acid methyl esters (FAME) is a crucial property of biodiesel and serves as an indicator of the transesterification reaction that converts vegetable oil into biodiesel. To facilitate the rapid estimation of FAME quickly in the biodiesel industries, simple methods such as measuring refractive index, density, and dynamic viscosity measurements were employed to monitor the progress of transesterification of castor oil to biodiesel. Blends of castor oil and biodiesel were mixed at different weights to find correlations between FAME content and refractive index, density, and dynamic viscosity measurements. The transesterification of castor oil with methanol was carried out to examine how the refractive index, density, and

Chloroxylenol is widely used in hospitals and other healthcare facilities to reduce the growth or the microbial load of pathogens. What’s more, biofilms are a major challenge in treating P. aeruginosa infections. The genes of PslA and pelA in two operons encode two polysaccharide polymers present in the biofilm of P. aeruginosa, Psl and Pel, respectively. Therefore, the present study aimed to evaluate the contribution of chloroxylenol to the inhibition of the P. aeruginosa biofilm. Here, the intensity of biofilms was determined by the crystal violet and microtiter plate method, whereas the RT-qPCR technique was adopted to illustrate the effect of chloroxylenol on the expres

The aim of this study is to investigation the possible association of SNP (rs16919255) in 3̍-UTR of AQP3 gene with the intracellular levels of HIF-1α, p53, and E2. Sixty–five breast tum

This study addresses the challenge of identifying Pliocene reservoir channels where small quantities of hydrocarbons can cause misleading Class III AVO anomalies, leading to inaccurate predictions of commercially unviable gas. It explores whether seismic attributes, such as far amplitude, in combination with well-log data, can confirm the presence of a prospective anomaly. This is especially relevant for the Kanaria Pliocene feature within the Baltim North area, offshore in the Nile Delta. To investigate this, we employed a range of post-stack seismic inversion techniques, including colored inversion, sparse spike inversion, band-limited inversion, and model-based inversion, to delineate the hydrocarbon-rich sands in the Kanaria Pliocene
