A Comparative Study to Control Coronavirus Disease COVID-19 with Treated Saturated Incidence Rate Using SIQR Model
Abstract: This paper aims at comparative study of SIQR epidemic model for coronavirus disease (COVID-19) with different treated saturated incidence rates. For the better understanding of this severe disease quarantine class is presented as sum of quarantine for susceptible individuals and quarantine from infected individuals. The Basic reproduction (R0) for different saturated incidence is found by using Next generation method. Different equilibrium points are calculated, and their conditions of existence are …

Entertainment Recommendation System
Abstract: For each of us, entertainment is a necessity for recharging our spirits and recharging our batteries. Also, entertainment restores our confidence in the workplace, allowing us to work more enthusiastically. Recommendation systems help you surface the things users love. Thus, we intend to make a recommender system that would be capable of recommending the users the movies, music, books, and games on their search and the popularity of the movie …

H-Restrainedness for Hypergraphs
Abstract: I introduce a new concept for hypergraphs called H-restrainedness. I prove that an H-restrained set of a hypergraph does not contain a vertex of minimality if and only if the compliment of S is an Hdominating set. I also prove a necessary and sufficient condition under which the restrainedness number of a hypergraph decreases when a vertex is removed from the hypergraph. I have proven that Let G be a …

Encryption-Decryption RGB Color Image Using Matrix Multiplication
Abstract: The most commonly used type of data on the Internet are RGB color images. To encrypt the color image the separation is done on the red and blue channels (R, G, B). Each channel is encrypted using a method called random matrix coding. After encryption a new image code is created. The functionality of this application compares with the performance of other techniques and demonstrates the benefits of using this …

Fuzzy Logic and Fuzzy Logic Sun Tracking Control
Abstract: Fuzzy logic could be a rule-based call method that seeks to unravel issues wherever the system is tough to model and where ambiguity or unclearness is thick between two extremes. Mathematical logic permits the system to be outlined by logic equations instead of complicated completely differential equations and comes from a thinking that identifies and takes advantage of the greyness between the 2 extremes. Mathematical logic systems are composed of …
