In this paper we investigate the generalized Pell numbers of order r ≥ 2 through the properties of their related fundamental system of generalized Pell numbers. That is, the generalized Pell number of order r ≥ 2; are expressed as a linear combination of a fundamental system of generalized Pell numbers. The properties of this fundamental system are examined and results can be established for generalized Pell numbers of order r ≥ 2. Some identities and combinatorial results are established. Moreover, the analytic study of the fundamental system of generalized Pell is provided. Furthermore, the generalized Pell Cassini identity type is provided.

The asymptotic homogenization method is applied here to one-dimensional boundary-value problems for nonlinear differential equations with rapidly oscillating piecewise-constant coefficients which model the behavior of nonlinear microperiodic composites, in order to assess the influence of interfacial imperfect contact on the effective behavior. In particular, a nonlinear power-law flux on the gradient of the unknown was considered. Several calculations were performed and are discussed at the end of this work, including a comparison of some results with variational ounds, which is also an important approach of this work.

Different types of mathematical models have been used to predict the dynamic behavior of the novel coronavirus (COVID-19). Many of them involve the formulation and solution of inverse problems. This kind of problem is generally carried out by considering the model, the vector of design variables, and system parameters as deterministic values. In this contribution, a methodology based on a double loop iteration process and devoted to evaluate the influence of uncertainties on inverse problem is evaluated. The inner optimization loop is used to find the solution associated with the highest probability value, and the outer loop is the regular optimization loop used to determine the vector of design variables. For this task, we use an inverse reliability approach and Differential Evolution algorithm. For illustration purposes, the proposed methodology is applied to estimate the parameters of SIRD (Susceptible-Infectious-RecoveryDead) model associated with dynamic behavior of COVID-19 pandemic considering real data from China’s epidemic and uncertainties in the basic reproduction number (R0). The obtained results demonstrate, as expected, that the increase of reliability implies the increase of the objective function value.

Aedes aegypti mosquitoes are the vector of diseases such as dengue, zika, chikungunya, and yellow fever among others. All the stages of development, eggs, larvae, pupa, and the adult of the species have its population modulated by meteorological variables, such as precipitation and temperature through affecting the productivity of breeding sites, metabolic processes, and others. Since adult females are responsible for transmitting the virus, the population of females becomes a direct indicator of the risk of infection. For this reason, some ongoing vector surveillance programs are based on adult female capture. In turn, all the stages of development have its population modulated by meteorological variables, such as precipitation and temperature, through productivity of breeding sites, metabolic processes and others. In this work, field data of capture of females was used to evaluate if a population dynamics model of Aedes aegypti under the effect of weather would be able to forecast field population. The nonlinear dynamic system model comprises: (1) four equations for the populations of the stages of development of the mosquito, designed for the ongoing surveillance program; (2) parametric dependencies of the rates of development on mean temperature and weekly accumulated precipitation. The dependencies on temperature and precipitation are modelled with aim of simplicity with the fewer number of parameters as possible. Temperature dependence is modelled based on values of the related literature under the assumption of existence of a optimum temperature for the rates, getting worse for extreme temperatures. The dependence on precipitation which is barely treated in experiments is modelled under the assumption of a monotonic dependence described by a power law with values estimated in orders of magnitude from data in the literature. By comparison with field data of an entomological indicator based on the number of Ae. aegypti females captured by a public health program in the city of Caratinga (Minas Gerais, Brazil), the model showed a significant correlation (R = 0.75). The result shows that the approach, if refined, can provide forecasting for of the population size.

The continuous evolution of 3D surveying and modelling techniques, using increasingly high-performance tools and applications, highlights the added value of these methods in the field of urban and architectural survey. In the case study presented, attention is focused particularly on applications useful for the planned maintenance of cultural heritage (CH). These tools and methods have a significant impact on the phases of interpretation and “physical” knowledge. They can also bring a critical contribution to the completion of models that are not only geometric but also semantic and informative, supporting 360-degree planning of the maintenance of our historical architectural heritage. This support for scheduled maintenance has been identified in the HBIM methodology, based on an integrated 3D metric survey. A three-year research project on this topic (Interreg Italy-Switzerland “MAIN.10.ANCE”, 2019-2022), partnered by Politecnico di Torino, is currently in the central phase. The main focus of the project is a UNESCO heritage site: the “Sacri Monti” (Sacred Mountains) of Italy and those in Canton of Ticino (Switzerland), with the need for a common and shared conservation plan.
3D测量和建模技术的不断发展，使用越来越高性能的工具和应用程序，突出了这些方法在城市和建筑测量领域的附加价值。在本案例研究中，重点关注对文化遗产(CH)的计划维护有用的应用。这些工具和方法对解释阶段和“物理”知识有重大影响。它们还可以为模型的完成做出重要贡献，这些模型不仅具有几何意义，而且具有语义和信息，支持360度规划维护我们的历史建筑遗产。这种对定期维护的支持已经在基于集成3D度量调查的HBIM方法中确定。关于这一专题的一个为期三年的研究项目(interregg意大利-瑞士”MAIN.10)。由都灵理工大学(Politecnico di Torino)合作的ANCE(2019-2022)项目目前处于中心阶段。该项目的主要焦点是联合国教科文组织遗产:意大利的“圣山”(Sacri Monti)和提契诺州(瑞士)的圣山，需要一个共同和共享的保护计划。
