  Abstract
  Working on symmetrical or asymmetrical data is complicated since each requires a different probability density function. Many statistical distributions can be used for these data types, where choosing one should be satisfied with the correct data type. So, we apply the ranked set sampling technique, which is essential in gaining data when dealing with units in a population is expensive. However, their classification is simple according to the variable of interest. The Rayleigh distribution has recently played a crucial role in analyzing symmetrical or asymmetrical complex data sets specifically in modeling claim and risk data used in actuarial and financial studies, and its density can take different symmetric and asymmetric possible shapes. It is proposed in various areas, such as reliability, survival, economics, actuarial science, and insurance. In this paper, we provide Bayesian estimation for a parameter of the Rayleigh distribution based on a simple random sample (SRS) and ranked set sampling (RSS) using two loss functions; the squared error loss function, and the linex loss function. The results of the simulation study showed that the Bayes estimates based on RSS are more efficient than the estimates based on SRS for different sample sizes of (n) and different values of the parameter ?.

  Abstract
  Performance estimation of an aircraft is required to make sure of the ability of the aircraft to perform conventional and mission specific maneuvers. An aircraft`s maneuverability is defined by its capability to alter attitude and speed along its three axes: longitudinal, lateral, and vertical. To acquire the performance of the aircraft for the establishing the operational envelope, initial operation certification and gradual expansion of the flight envelope, an aircraft system is studied directly by conducting some experiments with it or by using its mathematical model. Nowadays, mathematical modelling is more preferred over real flight testing as rehearsal of several situations cannot be practiced in real life. Further, drastically reduced training costs and increased efficiency of the required results. The conceptual model of the specific static maneuvers of the aircrafts can be converted to computer model via programming in a flight simulator such as Matlab, which then simulates the reality. The maneuvering capabilities of an aircraft are decided according to the mission to be performed. Therefore, the commercial passenger aircrafts are more stable and less maneuverable compared to the commercial transport and the military aircrafts, designed so keeping in mind the passenger safety and security as the foremost aim. Hence, it becomes very important to estimate the responses of a commercial aircraft for the maneuvers it performs under its operational flight envelope. Such estimation firstly requires a study of these maneuvers. Secondly, converting them into a matrix model and then simulating them in the Matrix Laboratory to obtain the required results for further analysis to arrive at conclusions. The conclusions required from the flight simulator are the coefficient of lift, drag; load factor, velocity and time estimation for a particular maneuver that an aircraft is capable to perform.

  Abstract
  This Study is centered on modifying SIRD mathematical model for cholera dynamics incorporating four control strategies namely: therapeutic treatment, Surveillance, vaccination and water sanitation. This study is limited to only cholera disease. Data were collected from the Gombe state Hospital for infectious disease and leprosy control in Zambuk. According to this study, total human population has been classified into four sub population such as susceptible humans, recovered humans, Infected Humans and the mortality rate of humans(Death). The susceptible class,Infected class and the recovered and the death category is being related with the homotopy perturbation method and the runge kutta method to observe the most efficient method to use to control the disease better.

  Abstract
  In this paper, we introduce a novel model called the area biased Transmuted Mukherjee-Islam (ABTMI) distribution, which generalizes the Transmuted Mukherjee-Islam distribution through an area biased transformation approach. We thoroughly explore the probability density function (PDF) and the cumulative distribution function (CDF) of the ATMI distribution. Additionally, we investigate the distinctive structural properties of the proposed model, including the survival function, conditional survival function, hazard function, cumulative hazard function, mean residual life, moments, moment generating function (MGF), characteristic function (CF), cumulant generating function (CGF), entropy measures, and Bonferroni and Lorenz curves. The model parameters are estimated using the maximum likelihood estimation method.

  Abstract
  This article discusses the use of elliptic curve cryptography (ECC) in creating secure communication schemes that do not require a pre-shared secret key. ECC, a type of public key cryptography, supports applications such as key agreement and digital signatures. Traditionally, secure communication necessitates a secret key exchange beforehand, but the paper demonstrates a method where multiple parties can publicly select a key without others being able to determine it. The proposed protocol leverages elliptic curves and secure multiparty computation (MPC) to allow secure communication over insecure channels, even in the presence of adversaries. MPC protocols enable parties to jointly compute functions of their private inputs while only revealing the output, with potential applications in privacy-preserving auctions, private DNA comparisons, private machine learning, and threshold cryptography.

  Abstract
  Real Bott manifolds are a type of compact, connected Riemannian manifolds without boundaries, notable as a unique and intriguing category of real toric varieties. This study focuses on identifying a set of topological invariants known as Stiefel-Whitney classes, which are crucial characteristic classes in the context of the set of integers modulo two. We computed the Stiefel-Whitney classes of real Bott manifolds. We applied the method to calculate the Stiefel-Whitney classes of the manifolds. The formula for determining the number of terms in each class was also given.
