Si l’on trouve facilement des estimations de l’espérance de vie individuelle, ce n’est pas le cas des estimations pour le couple. L’absence de ces estimations peut être préjudiciable aux couples qui prennent ensemble des décisions importantes concernant notamment la retraite, l’épargne et d’autres considérations qui viennent avec l’âge. De plus, l’utilisation des mesures disponibles pour les individus peut conduire à des erreurs, car cela produit une surestimation du nombre d’années que le couple peut s’attendre à vivre ensemble (espérance de vie commune) et une sous-estimation du nombre d’ann

This research focuses on biological systems with sexual reproduction in which female and male individuals coexist together, forming female–male couples with the purpose of procreation. The couples can originate new females and males according to a certain probability law. Consequently, in this type of biological systems, two biological phases are involved: a mating phase in which the couples are formed, and a reproduction phase in which the couples, independently of the others, originate new offspring of both sexes. Due to several environmental factors of a random nature, these phases usually

We prove an a posteriori error estimate for an inverse acoustic scattering problem, where the objective is to reconstruct an unknown wave speed coefficient inside a body from measured wave reflection data in time on parts of the surface of the body. The inverse problem is formulated as a problem of finding a zero of a Jacobian of a Lagrangian. The a posterori error estimate couples residuals of the computed solution to weights the reconstruction reflecting the sensitivity of the reconstruction obtained by solving an associated linaerized problem for the Hessian of the Lagrangian.

In this article, I analyze the effect of husbands' and wives' statuses on class self-placement. While the effect of wife's occupation is greater for employed wives than it is for their husbands, both employed women and their husbands attribute far greater importance to the husband's occupation. For couples in which the wife is a housewife, the class self-placement of both husbands and wives is far more strongly affected by husband's status than by wife's education. Overall, wives' characteristics make little difference either to husbands' or to wives' estimation of their social standing. The s

In this paper, we study a finite element computational model for solving the interaction between a fluid and a poroelastic structure that couples the Stokes equations with the Biot system. Equilibrium and kinematic conditions are imposed on the interface. A mixed Darcy formulation is employed, resulting in continuity of flux condition of essential type. A Lagrange multiplier method is used to impose weakly this condition. With the obtained finite element solutions, the error estimators are performed for the fully discrete formulations.

A social group may consist of sterile and fertile couples where sterile couples cannot reproduce. When the number of children for a fertile couple is distributed according to a Poisson distribution, the probability distribution of the number of children per couple in the social group is a mixture of a distribution singular at zero and a Poisson distribution. The estimation of the parameters in the mixture distribution is considered in this paper. Since the maximum likelihood (ML) metod does not provide estimates in closed forms, it is proposed to obtain the estimates using the EM algorithm. A

Abstract:When several realizations of an unknown recurrent signal are observed apart from a time expansion or compression, the classical way of estimating these time scaling factors is to take one signal as reference for the estimation. This approach does not take into account the common information between all possible couples of realizations. To achieve this task we use a Maximum-Likelihood based method, in a sub-optimal manner. Using some realistic assumptions and simplifications, we propose a tractable solution. The improvement of classical results is shown through a simulation whose concl

The peculiarity of parity-specific fertility decisions plays an important role in determining the family size. Couples control their family size by keeping the desirable number of children in mind. When women quit having children at younger ages, overall fertility begins to decline. As a result, information on stopping behavior of females is regarded critical in the assessment of fertility. In the present study, authors have analyzed stopping behavior of females for 1991 & 2014 and proposed two predictors based on stopping behavior of females for the estimation of total fertility rate.

Abstract. The uncertainties in values of coupled model parameters are an important source of model bias that causes model climate drift. The values can be calibrated by a parameter estimation procedure that projects observational information onto model parameters. The signal-to-noise ratio of error covariance between the model state and the parameter being estimated directly determines whether the parameter estimation succeeds or not. With a conceptual climate model that couples the stochastic atmosphere and slow-varying ocean, this study examines the sensitivity of state–parameter covariance

This article presents an anisotropic damage model for concrete that couples between elasticity and continuum damage mechanics. The formulation of constitutive model is based on the elastic strain energy in the framework of irreversible thermodynamics. The thermodynamic free energy is represented as a scalar function of elastic strain and damage tensors and used to derive the constitutive law and thermodynamic conjugate force of damage that is used to derive the dissipation potential. The damage evolution law is governed by the normality rule. The formulation of elastic strain energy of damaged

Background: The prevalence of contraception among married women, evaluated at 23%, is low in Cameroon. Maternal death rates, estimated at 782 deaths per 100,000 live births, are very worrying. The National Strategic Plan for Reproductive, Maternal, Newborn and Child Health (2015-2020) focuses on increasing contraceptive prevalence as a means to reduce maternal death. This paper identifies women’s bargaining power as a factor that may stimulate contraceptive use.

The fact that the intergenerational income elasticity (IGE)—the workhorse measure of economic mobility—is defined in terms of the geometric mean of children’s income generates serious methodological problems. This has led to a call to replace it with the IGE of the expectation, which requires developing the methodological knowledge necessary to estimate the latter with short-run measures of income. This article contributes to this aim. The author advances a “bracketing strategy” for the set estimation of the IGE of the expectation that is equivalent to that used to set estimate (rather than po

Robust indoor robot navigation typically demands either costly sensors or extensive training data. We propose a cost-effective RGB-D navigation pipeline that couples feature-based relative pose estimation with a lightweight multi-layer-perceptron (MLP) policy. RGB-D keyframes extracted from human-driven traversals form nodes of a topological map; edges are added when visual similarity and geometric–kinematic constraints are jointly satisfied. During autonomy, LightGlue features and SVD give six-DoF relative pose to the active keyframe, and the MLP predicts one of four discrete actions. Low vis

The reproductive years of women starts when she starts her menstrual cycle during puberty and capacity to have a child typically ends about age (45) years. However, it may be possible for a woman to become pregnant before her cycles end with menopause. Infertility affects 13–20 per cent of couples worldwide, regardless of race or ethnicity.

Abstract Acoustic pyrometry is a non-intrusive measurement technique that may have several applications in turbomachinery. This methodology estimates the gas temperature by measuring the time of flight of an acoustic wave moving through a medium. It can be accomplished by placing a sound source (emitter) and a set of microphones (receivers) on opposite sides of a section. The emitter generates a sound pulse, and the receivers detect it. Since the emitter-receiver distances are known and fixed, the average temperatures of the paths traversed by the acoustic pulse can be computed by estimating t

However, traditional tobacco yield estimation models have not considered the light energy utilization, carbon cycle, and ecological processes, resulting in the mechanisms poorly explained and the reduced monitoring accuracy. To address these limitations, a tobacco yield remote sensing monitoring model based on ecological process and carbon cycle was proposed.
