Pełny tekst źródłaDespite major achievements in eliminating long-established infections (as in the very well known case of smallpox), recent decades have seen the continual emergence or re-emergence of infectious diseases (last but not least COVID-19). They are not only threats to global health, but direct and indirect costs generated by human and animal epidemics are responsible for significant economic losses worldwide. Mathematical models of infectious diseases spreading have played a significant role in infection control. On the one hand, they have given an important contribution to the biological and epidemiological understanding of disease outbreak patterns; on the other hand, they have helped to determine how and when to apply control measures in order to quickly and most effectively contain epidemics. Nonetheless, in order to shape local and global public health policies, it is essential to gain a better and more comprehensive understanding of effective actions to control diseases, by finding ways to employ new complexity layers. This was the main focus of the research I have carried out during my PhD; the products of this research are collected and connected in this thesis. However, because out of context, other problems I interested in have been excluded from this collection: they rely in the fields of autoimmune diseases and landscape ecology. We start with an Introduction chapter, which traces the history of epidemiological models, the rationales and the breathtaking incremental advances. We focus on two critical aspects: i) the qualitative and quantitative assessment of control strategies specific to the problem at hand (via e.g. optimal control or threshold policies); ii) the incorporation into the model of the human behavioral changes in response to disease dynamics. In this framework, our studies are inserted and contextualized. Hereafter, to each of them a specific chapter is devoted. The techniques used include the construction of appropriate models given by non-linear ordinary differential equations, their qualitative analysis (via e.g. stability and bifurcation theory), the parameterization and validation with available data. Numerical tests are performed with advanced simulation methods of dynamical systems. As far as optimal control problems are concerned, the formulation follows the classical approach by Pontryagin, while both direct and indirect optimization methods are adopted for the numerical resolution. In Chapter 1, within a basic Susceptible-Infected-Removed model framework, we address the problem of minimizing simultaneously the epidemic size and the eradication time via optimal vaccination or isolation strategies. A two-patches metapopulation epidemic model, describing the dynamics of Susceptibles and Infected in wildlife diseases, is formulated and analyzed in Chapter 2. Here, two types of localized culling strategies are considered and compared: proactive and reactive. Chapter 3 concerns a model for vaccine-preventable childhood diseases transmission, where newborns vaccination follows an imitation game dynamics and is affected by awareness campaigns by the public health system. Vaccination is also incorporated in the model of Chapter 4. Here, it addresses susceptible individuals of any age and depends on the information and rumors about the disease. Further, the vaccine effectiveness is assumed to be partial and waning over time. The last Chapter 5 is devoted to the ongoing pandemic of COVID-19. We build an epidemic model with information-dependent contact and quarantine rates. The model is applied to the Italian case and explicitly incorporates the progressive lockdown restrictions.

Pełny tekst źródłaThis thesis is about the stability analysis of a coupled finite dimensional system and an infinite dimensional one. This kind of systems emerges in the physics since it is related to the modeling of structures for instance. The generic analysis of such systems is complex, mainly because of their different nature. Here, the analysis is conducted using different methodologies. First, the recent Quadratic Separation framework is used to deal with the frequency aspect of such systems. Then, a second result is derived using a Lyapunov-based argument. All the results are obtained considering the projections of the infinite dimensional state on a basis of polynomials. It is then possible to take into account the coupling between the two systems. That results in tractable and reliable numerical tests with a moderate conservatism. Moreover, a hierarchy on the stability conditions is shown in the Lyapunov case. The real application to a drilling mechanism is proposed to illustrate the efficiency of the method and it opens new perspectives. For instance, using the notion of practical stability, we show that a PI-controlled drillstring is subject to a limit cycle and that it is possible to estimate its amplitude

Pełny tekst źródłaWithin the non-traditional agricultural sector, fresh mango is the fifth most exported Peruvian fruit, with an average annual growth of 12.92 percent from 2002 to 2019. The United States is the second destination for Peruvian mango exports, covering an average of 24% percent of total sales in 2019. Given this, this research seeks to determine the factors that influenced the export of fresh mango from Peru to the United States during the period 2002 - 2019. The study had a mixed approach, with a descriptive, correlational and causal scope; With a non-experimental longitudinal design, where the variables Production, FOB Price, Exchange Rate, US Demand and US GDP were analyzed. In addition, of a descriptive nature, the variables Business Management, State Support and Climate were analyzed. For the quantitative analysis, information was obtained from secondary sources such as Adex Data Trade, BCRP, World Bank, MINAGRI and Bureau of Economic, where the data was processed through a multiple linear regression model. While, for the qualitative analysis, the semi-structured interview technique was used in which thirteen key actors belonging to entities of the private sector, public sector and related unions were interviewed where the information was processed through the Atlas Ti tool. Regarding the results of the investigation, it was concluded that the variables national production and demand from the United States influenced the export of fresh Peruvian mango to the United States.

Pełny tekst źródłaThis research addresses the real influence of the cracking of structural elements in the reduction of rigidity when a seismic event occurs. To do this, first, he described the problematic reality, the background and previous generalities about the topic to determine what type of building to use. Secondly, the theoretical framework exposed a set of fundamental concepts necessary to understand the cracking of concrete, the obtaining of effective inertia, the irregularity of buildings and a review of the considerations of foreign standards. In the third place, it was determined to work with 6 multifamily housing plans, of which 3 were regular structures and 3 were irregular. Likewise, the structures were subdivided into heights of 5, 10 and 15 floors, since they are the type of building that is most constructed in Lima. Afterwards, the geographic, use and geometrical parameters were found from the E-030 standard, to then perform the linear seismic analysis (static and dynamic). Then, the moment diagrams - curvature (beams, columns and plates) were made, so that from them, obtain a reduction factor of the gross inertia and perform a new seismic analysis considering this value as an effect of cracking. Finally, a comparative analysis was made between the results obtained according to the height in regular and irregular buildings.

Pełny tekst źródła--- In this thesis we stude the linear stability of the Timoshenko system. This problem consist in to show that the type of the semigroup is equals to the upper bound of the spectrum of the infinitesimal generator. This property is not true in general as was showed by Pazy and in differents international papers. This property is always valid in finite dimensional spaces. In infinite dimensional spaces this problem is open. That is to say it is not known the necessary and sufficient condition that a semigroup must verify in order to get the linear staibility. In this thesis we will show that the linear stability holds to Timoshenko system with fricctional dissipation, no matter the boundary condition the system verifies. This result improve the result obtained by Racke and Rivera. Keywords: Semigroups, Sobolev Spaces, Cauchy Problem, Polinomial Stability, Linear Stability.

Pełny tekst źródłaThis paper is an analysis from a business and statistical perspective of the Agrokasa company in order to find new potential markets that allow it to grow in the volume of its avocado exports and in profitability per Kg exported. To achieve the aforementioned, a previous analysis from a business approach has been used, to understand the context and business area. Once this is understood, the methodology of data science has been applied to find destination countries that are attractive to Agrokasa. The data set was obtained from different public and private sources such as Veritrade and Trademap, with which it was possible to identify 03 potential markets that were China, Russia and South Korea. In the analysis, different technological tools were used to compile, debug, process and visualize the data, such as Excel, Power Bi and Python. With which it was demonstrated the importance of seeing all the variables in a visualization that allows us to understand the behavior of the data and serves as a basis for decision-making. China was the market with the highest total FOB value exported in the analyzed period, which was from 2018 -2020, however, with a negative trend, but with a convenient average price. On the other hand, Russia was the market with the best growth prospects and South Korea with a better price per KG. Finally, for all markets, a data science technique with supervised learning with a predictive approach was used to forecast the imports of each of them in order to establish commercial strategies to penetrate them.

Pełny tekst źródłaThe main indicator to evaluate the quality of the soil as a subgrade in pavement design is the California Bearing Ratio (CBR). In many cases, it is not possible to obtain them by testing, at least at the required frequency, and they are very expensive. Therefore, the need to quantify this parameter through mathematical models that use easily determinable properties and will evaluate the effectiveness of a proposed stabilization solution. The purpose of this research work is to develop practical tools for the prediction of the CBR in expansive soil post stabilization with rice husk ash and lime. It is proposed to obtain mathematical models based on multiple linear regression using their index (% F, IP) and compaction (OCH, MDS) properties, which were generated by applying the SPSS Statistics software, whose resulting equation was: 〖CBR〗_f=46.116-0.526 %F+0.034 IP+0.218 OCH+5.06 MDS, which presents a very high correlation with R = 0.975 and an excellent goodness fit of R2 = 0.95. This means that the CBR response variable is 95% explained by the predictor variables %F, IP, OCH and MDS. The proposed regression model was applied to a section of the PE-8B highway in the San Martín region where it was found that the CBR value was found on average 272% when stabilized with the suggested study materials.

Pełny tekst źródłaPacific Feeder Services (PFS) is a general sales service agent (GSSA) whose main duty is to commercialize air freight capacity of different airlines; for example, Korean Air, Aeroméxico, Alitalia, Aerolineas Argentinas and Gol. These airlines do not have their own infrastructure in the country, so PFS acts as a representative of these airlines to their customers. In this research paper, the iterative methodology of data science will be used to address the problem related to demand, inasmuch as this is uncertain in some months of the year. To do this, the following hypothesis is proposed: Will a simple linear regression be the appropriate model to forecast the volumes of demand that PFS will have in the coming months? The objective to be achieved will be to project the demand through a simple linear regression, for which the data of the kilos exported by PFS in 2019 is being taken as a basis. Likewise, this academic research paper presents a functional data architecture and a technological data architecture that supports the simple linear regression model. The first explains what the inputs, storage and consumption required to implement the mentioned model are, while the second exposes the tools of the model. Finally, the research paper ends with the conclusions and recommendations associated with the correct implementation of the simple linear regression model in the specific case of PFS.

Pełny tekst źródłaThis research is aimed at improving the service levels of a roundabout by optimizing its capacity, based on changes in the geometric design elements. In this sense, an analysis and evaluation of the “Higuereta” roundabout was carried out, which is located in the district of Santiago de Surco, in the city of Lima in Peru. For this, a compilation of theoretical bases was carried out at an international level to know the fundamentals of geometric design. Thus, based on a deterministic mathematical model from the United Kingdom, Kimber 1980, which associates geometric parameters with circulating flow and shows that any change in a geometric design element is directly proportional to capacity, we can conclude that there are improvements. in service levels as long as we make significant variations in geometry. In the present investigation, improvements from a service level “F” to a “D” were evidenced. On the other hand, the roundabout was modeled from a micro simulation software, PTV Vissim 9, with the aim of being able to reflect through simulations the real traffic behavior before and after introducing changes in the geometric parameters. It was concluded that there are improvements in service levels per access, from a “D” to a “C. Finally, to be certain that the model reflected reality, it was calibrated through adjustments in the driver's behavior parameters and validated from a statistical indicator.

Pełny tekst źródłaIn the first experiment high spin states in 194Tl, excited through the 181Ta (18O, 5n) heavyion fusion evaporation reaction were studied using the AFRODITE array at iThemba LABS. The γ-γ coincidences, RAD ratios and linear polarization measurements were carried out and the previously known level scheme of 194Tl was significantly extended. A total of five rotational bands four of which are new were observed. A pair of rotational bands associated with the πh9/2 ⊗ νi−1 13/2 configuration at lower spins and with the πh9/2 ⊗ νi−3 13/2 configuration at higher spins was found and interpreted as the first possible chiral bands followed above the band crossing. The two 4-quasiparticle bands show exceptionally close near-degeneracy in the excitation energies. Furthermore close similarity is also found in their alignments and B(M1)/B(E2) reduced transition probability ratios. In the second experiment lifetimes in 194Tl were measured using the DSAM technique with the excited states in this nucleus populated through the 181Ta (18O, 5n) reaction. A total of 25 lifetimes and 30 reduced transition probabilities of magnetic dipole B(M1) and electric quadrupole B(E2) have been evaluated. Furthermore B(M1) and B(E2) reduced transition probabilities in Bands 1 and 4, which have been regarded as chiral candidates, were found to be close to each other and reveals strong splitting along spin values. This further supports the proposed chiral nature of these two bands.

Pełny tekst źródła--- In this Thesis work is carried out a Situational Analysis to the Grupo Digigraf S.A. Enterprise, using the Systems Approach Methodology or Systemic Approach. The Situation Analysis provides us with information that guides us to set focus in the reality of the Company. After to make a thorough analysis of all company subsystems, is determined that the company has a serious problem of low profitability economic to be solved; continuing with the analysis of internal processes, is possible to detect that the main cause that generates this problem is the wrong method using by the company to make cuts rolls of film used as the main input in the production process. To solve the problem is used the Linear Programming that permit build a mathematical model that describe the problem and to solve it we used the Simplex Method for obtain the optimal Solution that will resolve the problem and therefore improve the Company Situation. Finally, is proposed this model of solution which will replace the current methodology is performed in the company, and is recommended for early implementation, in order to promote the improvement of the Company.

Pełny tekst źródłaThe present investigation is mainly related to the use of the Standard Penetration Test (SPT) and the Direct Shear Test, through these tests results were obtained that were used to formulate a correction expression. The study was carried out on sandly soils with a percentage of fine less than 12 % in the Lima districts of Villa El Salvador and Ventanilla. Due to the great diffusion and use of the Direct Shear Test it is of utmost importance that the results obtained are as reliable as possible, since it depends on the design of foundation structures, slopes, embankments, among others. However, there is great difficulty in obtaining undisturbed samples from sandy soils, which induces to Direct Shear tests being carried out, reshaping the specimen to its natural density, moisture content, compactness and others, this could generate a considerable variation in the results (soil resistance parameters). Based on the above, it is considered necessary to find a way to counteract this problem, for this reason it is proposed to formulate a correction expression for the friction angle obtained in the Direct Shear tests of remoulded samples. For the formulation of said expression, the Microsoft Excel program was used to perform a multiple linear regression with the variables related to the friction angle, resulting in a correction expression that improves the friction angles of the Direct Shear Test by 63.69 %.
