This article introduces and discusses a new three-parameter lifespan distribution called Zero-Truncated Poisson Pareto distribution ZTPP. that is built on compounding Pareto distribution as a continuous distribution and Zero-Truncated Poisson distribution as a discrete distribution. Various statistical properties and reliability characteristics of the proposed distribution have been investigated including explicit expressions for the moments, moment generating function, quantile function, and median. With three parameters, the suggested distribution has an advantage over other distributions in that it makes estimating the model parameters simpler. To estimate the unknown parameters of the ZTPP distribution, the maximum likelihood method, and L. Moments method are employed. Moreover, a real data set is used to evaluate the significance and ensure the applicability of the proposed distribution as compared to other probability distributions. The derived model proved to be the best compared to other fitted models, where the criteria values of (AIC), (CAIC), and (BIC) are minimum values by using the ZTPP distribution. The proposed model is hoped to attract a wider application.

Black hole (BH) formation via extreme star (ES, mean density comparable to or larger than neutron mean density) instability, due to increasing mass, is conceived as a phase transition from ordinary (energy + matter) to ENTER, an indivisible ideal fluid. BHs and ESs are re-lated to classical, heterogeneous disks of equal mass, equatorial radius, moment of inertia, where surface density distribution obeys a power law, by use of a principle of corresponding states [5]. With regard to static (TOV) and equatorial breackup (EQB) configurations, ES reduced (di-mensionless) parameters are inferred [19] and revised [5] from earlier results, and compared to the following BH relations: (reduced moment of inertia)-(reduced angular momentum); (swivelness, / Ω = β Ω R/c )- (reduced angular momentum); (angular momentum)-mass in logarithmic plane for sequences of configurations where reduced angular momentum remains unchanged. ES (reduced moment of inertia)-compactness relation, inferred in earlier investigations for a large number of equations of state (EOSs) [3][23] and sequences of constant reduced angular momentum [3], is extrapolated across the instability region, 38 < β < 12 , and results are consistent with related BH counterparts, β = 12 . Similarly to BHs, classical heterogeneous disks associated via a principle of corresponding states exhibit surface density distribution increasing with radial distance, contrary to TOV and EQB configurations with assigned EOS, which allows the formulation of an empirical criterion for ES stability.

The paper addresses uncertainty analysis in decision theory by applying imprecise probabilities to a herding behavior model, which describes imitative behavior and explains the informational cascade phenomenon. In the literature, the application of the principle of rationality in herding behavior generates informational cascades, i. e., sequences of actions in which each agent makes their choice by observing the decisions taken by those who acted before them, regardless of the private signal they own. Since the probability distribution of the signal may be hard to identify in some cases, this paper studies the herding behavior model by considering imprecise the signal probability. In the simplest case of a binary signal model, the agent’s private information is described by using a set of probability measures and assuming that the signal probability ranges in a probability interval. The paper aims to test the herding behavior model robustness when some assumptions no longer hold due to imprecise probabilities and prove that an informational cascade may occur even with a further noisy signal.

Despite the many difficulties and challenges of the present, it is desirable that current generations shape development models that are not likely to jeopardize the chances of future generations to meet their needs. To achieve this, each physical or moral individual is supposed to play a role. For all those who are aware and determined to be part of the dynamics of sustainable

We generalize First order Impulsive Dynamic equation on time scale to quantum stochastic calculus of Hudson and Parthasathy formulation of quantum stochastic calculus on a certain locally convex space. We establish existence result for the quantum impulsive dynamic equation on time scale considering impulse at fixed moment, we apply the non-commutative analogue of Leray-Schauder and Arzela Ascoli fixed point theorems in establishing the existence of solution.

The statistical modeling of the problem of poverty is a major challenge given Burundi’s economic development managment system. Innovative economic optimization systems are widely needed to face the problem of the dynamic of the poverty in Burundi. The Burundian economy shows an inflation rate of1.5% in 2018 for the Gross Domestic Product growth real rate of 2.8% in 2016. This research concerns the FDP ++ R 2023 A Algorithm for Performance Improvment of Burundi management system. The SATINOV management sciences and decision support in Africa. The aim is to find a management system model that contributes to solving the problem of poverty in Burundi. This model solves an optimization problem combining the variables of production, consumption, budget, human resources and available raw materials. Scientific modeling and optimal solving of the poverty problem show the tools for measuring poverty rate and determining various countries’ poverty levels when considering advanced knowledge for performance improvment of Burundi management system.
