The pervasiveness of organization framework in big business and the way that Web Convention (IP) is the convention that interfaces, finds and recognizes gadgets on an organization has made Voice over web convention a strong help stage for moving voice approaches an organization. In order to transmit voice over an IP network, businesses have increasingly turned to voice over internet protocol (VoIP) in recent years. However, like any other technology, it possesses a number of advantages and promising characteristics that give it an advantage over the conventional Public Switched Telephone Network (PSTN), despite the fact that it also carries a number of risks [22]. The effectiveness and efficiency of voice over IP are determined by resonance reparation, packet-loss rate, and delay. This work demonstrates the advantages and applications of voice service over internet protocol. The advantages of controlling adaptive rate algorithms to maintain real-time adaptive voice over IP processing were the subject of the study. Consequently, the proposed technique's implementation analysis of RLS, Sign-Error RLS algorithms is presented here.
The focus on utilizing reclaimed construction materials arises from the surge in construction and demolition waste caused by rehabilitation, natural disasters, and technological disasters. The measures taken to create recycled concrete adhere to three primary criteria: conservation of natural resources, utilization of increasing waste, and savings in energy and finances. This research paper examines the durability properties of concrete produced by partially replacing Recycled Coarse aggregate and seashore sand. The properties investigated include water absorption test, porosity, Alkalinity, Sorptivity, acid resistance test, and Rapid chloride penetration test. The compressive strength test determined that the optimal replacement level for recycled coarse aggregate (RCA) in concrete is 40%. The study on durability properties involved testing concrete with a constant 40% recycled coarse aggregate and varying replacement levels for river sand with both untreated and treated seashore sand (0%, 10%, 20%, 30%, 40%, 50%, and 100%). The results were compared to those of conventional concrete, revealing that recycled coarse aggregate concrete combined with seashore sand yields durability properties comparable to conventional concrete.
This study presents a novel multiband pink ribbon patch antenna design with coaxial line feeding. Then, a pink ribbon patch antenna was created, and the results were reported in terms of gain, bandwidth, and return loss. For improved performance, it was suggested that the ground layer of the antenna be modified by cutting a ring notch through the centre. The patch and ground layers of the suggested design were made of copper, and the substrate layer was made of polyimide with a 0.75 mm thickness. According to the results, the improved design performs better and can work efficiently at 1.575 GHz and 2.1 GHz, which may be dedicated for, while the pink ribbon patch antenna can only run at 1.575 GHz, which is applicable for GPS applications.
Providing robust image watermarking scheme for attending multimedia security stills a challenge nowadays. Numerous methods have been proposed, employing diverse algorithms to enhance the secure transmission and reception of multimedia. This paper introduces a method to embed a watermark image into the host image by applying Discrete Cosine Transform (DCT) and Discrete Fourier Transform (DFT). DCT is employed to identify suitable frequencies for seamless embedding, while DFT is utilized to capture the magnitude and phase characteristics of the host image. To enhance security levels, Ikeda maps are integrated into the scheme. Additionally, Arnold's maps and Singular Value Decomposition (SVD) are applied to identify optimal points that minimize any degradation of the host image quality. The results obtained from evaluating the proposed system using Peak Signal to Noise Ratio (PSNR) values indicate the strength of the system in terms of watermark robustness and the difficulty for an attacker to discriminate or perceive the presence of the watermark. These findings highlight the effectiveness and reliability of the proposed system is more described in the rest of the paper.
Antiseptic is a chemical substance that destroys microorganisms or inhibits work to prevent an infection system. One example of an antiseptic is alcohol. Alcohol, a primary ingredient for hand sanitizers, is now experiencing shortages due to the pandemic in Indonesia. These requests are generally intended for the sterilization and sanitation needs of a company that operates as an alcohol distributor, PT. X has received a lot of requests for alcohol due to the Covid-19 pandemic. Modeling and simulation can be done using the Monte Carlo method to meet the above requirements. After seeing the number of product requests, the next step is to send the product until the customer well receives it. Delivery is unbeatable with existing demand. The problem was that the product delivery was unbeatable with the vehicle capacity. So the shipping costs are pretty high. Companies can use the Vehicle Routing Problem (VRP) method that arises. The solution to the VRP problem is obtained by the Saving Matrix method. From this research, the expected demand (expected value) of 163.2 drums of alcohol per day differs from the average demand of 159 drums of alcohol using a simulation for 30 days and distribution routes, giving a distance of 228. km or with a proportion of savings of 31.84%.
