Removable dental prostheses remain a reliable treatment for edentulous patients. Conventional fabrication requires multiple steps, whereas computer-aided design and manufacturing (CAD-CAM), particularly 3D printing, offers faster and more cost-effective alternatives. This in vitro study aimed to evaluate the effect of sandblasting on surface roughness and shear bond strength of silicone soft liner bonded to 3D-printed and heat-cured acrylic denture base materials. Eighty specimens were divided into four groups: heat-cured control, 3D-printed control, heat-cured sandblasted, and 3D-printed sandblasted. Surface roughness was measured using a profilometer, while shear bond strength was tested with a universal testing machine. D

Precipitation is the most important weather parameter, which has direct and indirect effects on life on our planet.  One of the most relevant climate change consequences is extreme weather conditions, such as floods and droughts.  Up to now, climate model projections have remained uncertain, therefore, more accurate precipitation modelling techniques are necessary. Due to the complexity of relationships among metrological parameters, traditional statistical modelling tools are ineffective in forecasting and predicting weather conditions. In this study, data mining techniques were applied to metrological data to predict daily precipitation using Multilinear regression (MLR) along with two artificial intelligence (AI) te

This research aims to reduce the number of experiments by using the Taguchi technique. It will be applied on adding copper nano particles and study it's effect on shape recovery for a shape memory alloy (83% Cu- 13% Al- 4%Ni). Different proportions of nano were added to the alloy in return for changing the proportion of copper while maintaining the proportions of nickel and aluminum constant.  Powder metallurgy technique was used to manufactured   the samples. Two types of tests were performed: physical tests, including X-ray diffraction (XRD) and scanning electron microscopy (SEM), were used to inspect raw materials before manufacturing and to inspect samples after manufacturing. A mechanical test of the shape memory

The key benefits connected with Roller-Compacted Concrete Pavement (RCCP) technology are costs reduction of life-cycle, shrinkage decrease, opening to traffic at an earlier time, and a cooling of the city's core are. This technology received much consideration recently for applications in highway tenders. Several attempts worked on instill sustainable implementation in RCCP using alternate materials. This work presented a thorough review of the literature on alternative materials for RCCP published between 1997 and 2021. Recycled concrete and asphalt pavement aggregates are two examples of alternative materials to traditional quarry rock that have been studied. Critical evaluations of th

This paper proposes a new strategy to enhance the performance and accuracy of the Spiral dynamic algorithm (SDA) for use in solving real-world problems by hybridizing the SDA with the Bacterial Foraging optimization algorithm (BFA). The dynamic step size of SDA makes it a useful exploitation approach. However, it has limited exploration throughout the diversification phase, which results in getting trapped at local optima. The optimal initialization position for the SDA algorithm has been determined with the help of the chemotactic strategy of the BFA optimization algorithm, which has been utilized to improve the exploration approach of the SDA. The proposed Hybrid Adaptive Spiral Dynamic Bacterial Foraging (HASDBF)

In recent years, the world witnessed a rapid growth in attacks on the internet which resulted in deficiencies in networks performances. The growth was in both quantity and versatility of the attacks. To cope with this, new detection techniques are required especially the ones that use Artificial Intelligence techniques such as machine learning based intrusion detection and prevention systems. Many machine learning models are used to deal with intrusion detection and each has its own pros and cons and this is where this paper falls in, performance analysis of different Machine Learning Models for Intrusion Detection Systems based on supervised machine learning algorithms. Using Python Scikit-Learn library KNN, Support Ve

The intellectual and revolutionary movements that have emerged since the beginning of the second half of the first century of the Islamic era did not appear suddenly, but must have preceded by a social consciousness, multi-forms, in the forefront of class awareness and religious awareness, and awareness was more painful, Of the society of the Arabian Peninsula - before Islam - feel it and suffer from it, a sense of injustice and tyranny, oppression and humiliation, and the destruction of dignity as well as poverty and hunger, and the injustice of tribal laws, and tyranny of each other and the tyranny of their heads on the tribes members and families belonging to this tribe or hill

There are serious environmental problems in all countries of the world, due to the waste material such as crushed clay bricks (CCB) and in huge quantities resulting from the demolition of buildings. In order to reduce the effects of this problem as well as to preserve natural resources, it is possible to work on recycling (CCB) and to use it in the manufacture of environmentally friendly loaded building units by replacing percentages in coarse aggregate by volume. It can be used as a powder and replacing of percentages in cement by weight and study the effect on the physical and mechanical properties of the concrete and the masonry unit. Evaluation of its performance through workability, dry density, compressive strength, thermal conduct

The adsorption of Cr (VI) from aqueous solution by spent tea leaves (STL) was studied at different initial Cr (VI) concentrations, adsorbent dose, pH and contact time under batch isotherm experiments The adsorption experiments were carried out at 30°C and the effects of the four parameters on chromium uptake to establish a mathematical model description percentage removal of Cr (VI). The
analysis results showed that the experimental data were adequately fitted to second order polynomial model with correlation coefficients for this model was (R2 = 0.9891). The optimum operating parameters of initial Cr (VI) concentrations, adsorbent dose, pH and contact time were 50 mg/l, 0.7625 g, 3 and 100 min, respectively. At these conditions, th

This work investigates the impacts of eccentric-inclined load on ring footing performance resting on treated and untreated weak sandy soil, and due to the reduction in the footing carrying capacity due to the combinations of eccentrically-inclined load, the geogrid was used as reinforcement material. Ring radius ratio and reinforcement depth ratio parameters were investigated. Test outcomes showed that the carrying capacity of the footing decreases with the increment in the eccentric-inclined load and footing radius ratio. Furthermore, footing tilt and horizontal displacement increase with increasing the eccentricity and inclination angle, respectively. At the same time, the increment in the horizontal displacement due t

Profiling is one of the important problems in mechanical engineering and industry because of its large applications in the field of cutting tool. Most papers and researches deal with the problem of profiling of involute profile. The problem of direct profile design consists in determination of profile tool if profile of gear is defined. This paper deal with problem of determination non-involute profile for helical surface in which profile of tool is defines and this problem called the reverse profile problem There are very large applications of this problem in cutting tool, for example cutting of helical surface (flutes) of twist drill with disc (wheel) tool and generating of helical surface for hops with disc (wheel) tool. To solve this
