This paper presents an analysis for the experimental set up of a double toroid variable inductor (VI) that is fed by a DC-DC converter. The main objective is to analyze the behaviour of the VI for different power levels, in particular the influence of the control circuit to regulate the inductance of the main winding. By observing the waveform of the main current winding, it is possible to demonstrate the abili...
LLF (Least Laxity First) scheduling, which assigns a higher priority to a task with a smaller laxity, has been known as an optimal preemptive scheduling algorithm on a single processor platform. However, little work has been made to illuminate its characteristics upon multiprocessor platforms. In this paper, we identify the dynamics of laxity from the system’s viewpoint and translate the dynamics into LLF multi...
Risk assessment is one of the main pillars of the framework directive and other directives in respect of health and safety. It is also the basis of an effective management of safety and health as it is essential to reduce work-related accidents and occupational diseases. To survey the hazards eventually present in the workplaces the usual procedures are i) gathering information about tasks/activities, employees...
A leishmaniose é a terceira zoonose parasitária mais comum no mundo e uma das doenças mais negligenciadas. Atualmente, são conhecidas várias espécies de Leishmania, sendo Leishmania infantum o agente etiológico da leishmaniose visceral, cujo principal reservatório e hospedeiro parasita é o cão. A transmissão ocorre através da picada de flebotomíneos fêmeas infetados e representa um grave problema veterinário e ...
O Direito registal surgiu há vários anos no nosso ordenamento jurídico e, como todos os ramos do Direito, tem vindo a evoluir, aperfeiçoando as suas normas de forma a proporcionar maior segurança jurídica e, consequentemente, proteger de forma mais eficaz o comércio jurídico sobre imóveis, bem como os interesses dos cidadãos e das empresas. O Direito registal português é enformado por determinados regras ou pri...
Mental health decline is one of the main responsible factors for augments in health care costs, and diagnosis of Alzheimer’s disease (AD). Some studies stated physical exercise is useful for reduction in cognitive decline and AD. Moreover, a recent review argued that evidence are scarce due to few studies published and lack of configuration information of exercise protocol, such as intensity and duration of exe...
.The research proposed herein seeks to improve solar irradiance magnitude and variability results produced by the Weather Research and Forecasting (WRF) model using a novel offline coupling procedure (OCP). The OCP includes simulations in clear sky conditions, where the effects from varying atmospheric composition depend on the broadband clear sky model used, on cloud attenuation and on decomposition techniques...
The application of mathematical methods and computer algorithms in the analysis of economic and financial data series aims to give empirical descriptions of the hidden relations between many complex or unknown variables and systems. This strategy overcomes the requirement for building models based on a set of ‘fundamental laws’, which is the paradigm for studying phenomena usual in physics and engineering. In s...
Esta dissertação de tese descreve o desenvolvimento de um projeto cujo objetivo principal é melhorar o ambiente de testes da Continental, alinhando-o com os padrões da Indústria 4.0. O atual ambiente de testes da Continental enfrenta várias limitações que comprometem diretamente a con abilidade e a e ciência dos processos de validação de novas soluções. A principal limitação reside na incapacidade de replicar a...
