Rebuilding damaged structures that already exist is one of the major issues facing civil engineers. To strengthen, repair, or retrofit these defects, common procedures include external pre-stressing, fiber-reinforced polymer wrapping, jacketing with steel and concrete, and patch repair. This study proposes using ultra-high-performance concrete strips as a strengthening material for the rehabilitation of damaged RC beams. UHPC provides high compressive strength, making it a highly desirable material in technical applications. A total of six reinforced concrete beams with a cross-section of 150
Sodium silicate is a compound consisting of sodium (Na), silicon (Si), and oxygen (O), which is often used in industry as an adhesive, concrete hardener, or as an additional ingredient in detergents. Silica nanoparticles are particles that have very small sizes, often in the nanometer range, which gives them a very large surface area compared to their volume, this characteristic makes them very efficient at capturing and binding molecules or ions from the surrounding environment. One of the main reasons why sodium silicate is used in the synthesis of silica nanoparticles is its relatively chea
Assume that G = (V, E) is a finite, connected, basic graph. If, for every y ∈ V(G), the code of y with respect to T, represented by CT (y), which is defined as CT (y) = (d(u1, y), d(u2, y),.., d(uk, y), is different for distinct y, then the subset T = {u1, u2,..., uk}of V(G) is said to be a resolving set. Dim (G) represents the dimension of G, which is the least cardinality of a resolving set. The resolving set S is secure if, for every t ∈ V – S, there exists r ∈ S such that (S – {r}) ⋃ {t} is a resolving set. The secure metric dimension of 𝐺 is the cardinal number of the minim
In order to lessen the destructive effects of uncontrolled wildfires on both human settlements and natural ecosystems, wildfire detection become more important. This project focuses on leveraging deep learning techniques for the detection of wildfires, emphasizing their severe threat to property, human life, and ecosystems. Timely and accurate wildfire detection is crucial for effective response and mitigation. The study utilizes convolutional neural networks (CNNs) to analyze diverse data sources like satellite photos, aerial images, and real-time video feeds, eliminating the need for human f
The need for higher data transmission speeds in various applications is driving the need for broader operational frequency ranges in upcoming 5G/6G communication systems. Consequently, this imposes stringent requirements for the development of appropriate antennas. Reflectarrays (RAs) are being considered as promising options for supporting 5G/6G systems because of their many benefits, including as high gain, beam shaping, beam scanning, reconfigurability, and multi-beam features. Nevertheless, the poor efficiency of reflectarrays is attributed to their narrowband nature. This work comprehensi
