Periodic Solutions of the Generalised Logistic Equation

We study the periodic generalised logistic equation which is parameterised and includes a degenerate potential. Such an equation can be used to model a population density within a habitat that has refuges in which the population experiences no mortality. It is assumed that all parameters vary periodically - for example to take account for temperature changes of seasons. Under no assumption on the boundary of the domain, and the form of the degenerate potential, we show the existence of a periodic solution. It is necessary for the parameter to fall within a predetermined range for a periodic solution exist and so we are also able to examine properties of a family of periodic solutions, determined by the parameter range. We show that this family of periodic solutions bifurcate and under additional assumptions we are able to show they tend to a blow-up solution of an equivalent logistic equation. In contrast to the existing literature, we have greatly relaxed assumptions on the domain and the degenerate potential. Additionally, we explore how the parabolic maximum principle affects where periodic solutions remain bounded in the domain. We provide examples showing that the solutions remain bounded even in some places where the potential is zero, in contrast to the corresponding elliptic problem

Thermal Sensitivity Analysis of a High Power Density Electric Motor for Aeronautical Application

International audienceThis paper studies the sensitivity of the thermal behavior of a high power density electric motor to some parameters. The machine is conceived for aeronautical application. It is of Permanent Magnet Synchronous type totally enclosed, configured with a double cooling system around the stator and in the shaft. A Lumped Parameter Thermal Model of the motor is primarily elaborated to explore hot spot points. Then, the thermal parameters, related to the heat evacuation from the critical zones, are investigated. Windings' thermal conductivity as well as laminations' one appear to influence the most the hottest regions of the machine

Numerical Approach to Determining Windings' Thermal Conductivity

International audience Abstract-This study concerns the characterization of windings' thermal conductivity, which is of primordial importance for thermal management of a high power density electrical machine. Indeed, such machines exhibit high heat dissipation in the windings' area. A precise knowledge of this conductivity value is therefore important for good thermal predictions. Unfortunately, the heterogeneity of the windings and the heat production repartition make it difficult to calculate easily winding's equivalent thermal conductivity. The influence of four thermal and geometrical parameters on the windings' equivalent thermal conductivity is numerically studied on a Finite Element Analysis software, allowing determining more precisely this characteristic. The impregnation's thermal conductivity, the conductors' number, the fill factor and the configuration of the copper wires inside the slot are investigated. The equivalent thermal conductivity, principally controlled by the impregnation thermal conductivity, the slot fill factor and the conductors' disposition, is expressed in terms of the first two parameters in its worst-case configuration.

Optical Analysis of a Hexagonal 42kWe High-flux Solar Simulator

AbstractA 42-kWe high-flux solar simulator with hexagonal reflector symmetry has been designed, built and optically characterized at IMDEA Energy Institute, Spain. This facility makes possible the lab-scale generation of a quasi-uniform high radiation flux density and high stagnation temperatures and it will be used as a platform for analyzing processes under concentrating solar energy conditions; for instance, central receivers in concentrating solar power plants and solar fuel production process in thermochemical reactors. The high-flux solar simulator consists of seven reflector-lamp pairs arranged in the center and vertices of a regular hexagon. The 6-kWe Xe short arc lamps are allocated in the primary focus of the corresponding truncated ellipsoidal reflector. This hexagonal symmetry provides compactness and quasi-uniform spatial distribution of the radiation at the system common focal plane.This work presents the experimental characterization of the solar simulator optical performance. Preliminary measurements indicate an average flux density at the focal plane of 3.5 MW/m2 that means 3,500 suns (1 sun = 1kW/m2) and stagnation temperature of approximately 2,800K

Diseño y optimización de plantas solares FV en diferentes latitudes de méxico

CIES2020 - XVII Congresso Ibérico e XIII Congresso Ibero-americano de Energia SolarRESUMEN: En este estudio se compara el rendimiento de tres configuraciones geométricas: Estructura Fija y Seguidores de un eje “1X” y de dos ejes “2X” para 12 sitios de distintas latitudes en los Estados Unidos Mexicanos, desde 16.85ºN a 31.66ºN. Para cada configuración geométrica y latitud se obtiene la producción específica final Yf en función del Ratio de Ocupación GCR (Ground Cover Ratio). A su vez, para cualquier GCR, se optimiza el ángulo de inclinación "β" en Estructura Fija y el GCRNS direccional (en dirección Norte-Sur) en el caso del seguidor de dos ejes. Con respecto a la Estructura Fija y para sitios con baja fracción difusa, se observa que el Seguidor 1X tiene una ganancia que oscila entre el 23,03% y el 24,04% con la latitud, mientras que el Seguidor 2X tiene ganancia más pronunciada, desde el 30,96% hasta el 36,04%. En los sitios con una fracción de difusa similar, la ganancia del Seguidor 2X con respecto al Seguidor 1X aumenta con la latitud, de 5,58% (latitudes bajas) a 10,33% (latitudes altas). Cuanto menor sea la fracción de difusa, más adecuado será apuntar al sol; cuanto mayor es la fracción de difusa, más apropiado apuntar al cenit.ABSTRACT: This study compares the performance of three geometric configurations: Fixed Structure, one-axis and two-axis trackers for 12 sites at different latitudes in Mexican United States, ranging from 16.85ºN to 31.66ºN. For each geometric configuration and latitude, the final specific production Yf is obtained as a function of Ground Cover Ratio GCR. In turn, for any GCR, the inclination angle "β" is optimized for Fixed Structure, and the directional GCRNS (in the North-South direction) for two-axis tracker. Compared to Fixed Structure, and for sites with low diffuse fraction, it is observed that one-axis tracker has a little gain change with latitude, between 23.03% and 24.04%, while two-axes tracker has more noticeable gain change, ranging from 30.96% to 36.04%. At sites with a similar diffuse fraction, the gain of two-axis tracker relative to one-axis increases with latitude, from 5.58% (low latitudes) to 10.33% (high latitudes). The smaller the diffuse fraction, the more suitable will be pointing at the sun, the greater the diffuse fraction, the more appropriate pointing at the zenith.info:eu-repo/semantics/publishedVersio

ConnectionWatch: Passive monitoring of round-trip times at end-hosts

International audienceThe current Internet offers a diverse set of applications for end-users (e.g., online gaming, IPTV, VoIP, VoD). These applications require a timely delivery of packets to avoid the deterioration of user-perceived performance. Slow web- browsing, momentarily drops of voice in Internet telephony and lagging remote connections are some of the most com- mon problems that affect the usability of Internet services. Ideally, if applications had access to measurements that quan- tify network performance, they could dynamically adapt to network conditions and improve user satisfaction. Most im- portantly, when application service quality falls below ex- pectations, online measurements help users understand who to blame and what to do to bypass the problem. We propose a troubleshooting tool that runs at end-hosts to automatically detect and diagnose performance degrada- tions. The tool has three aspects: detection of performance degradation, identification of the location of the problem and characterization of the potential causes. In this work, we focus on the detection aspect, which requires continuous monitoring at end-hosts

Can Lebanon Export Cannabis for Medicinal Purposes?

The sale and consumption of cannabis are becoming more broadly accepted worldwide as research into its medicinal uses accelerates. Revenue in the global medical cannabis market is projected to reach 12.92 billion US dollars (USD) in 2023, and is expected to grow by 13.16% annually, resulting in a market volume of USD 23.97 billion by 2028. Moreover, Colombia, Costa Rica, Malaysia, Morocco, Thailand, Ukraine, the United States, and European Union countries have created regulatory frameworks for cannabis derivatives manufacturing and export and import licenses. As we previously argued, the goal of exporting cannabis from Lebanon for pharmaceutical processing and medicinal purposes should be welcome, despite many misunderstandings about Lebanon’s informal cannabis sector, as well as what would be required to establish a formal sector and ensure buy-in along the cannabis cultivation and export value chain. Among these challenges are cannabis importing country requirements and Lebanon’s ability to meet them
