Static analysis of a lamppost according to Eurocode EN-40

When people move around a town, at some point in their journey they need to cross the road using a dedicated crosswalk. However, crossing is not always done safely due to weather conditions, lack of visibility or distraction. The VALLPASS project, aims to install two lampposts in opposite positions to the direction of crossing, with various functionalities and technological innovations, creating a luminous tunn...

Thermal analysis for testing underground battery location

The energy storage batteries, employed in solar systems installed on lampposts, are usually placed in devices such as switchboards fixed at an elevation near the top of the column. However, this storage solution becomes inefficient, because it is not possible to guarantee the control of the working temperature of the batteries, due to the low thermal insulation capacity of these storage devices. In this sense, ...

Foundations and description of a program to promote mental health and prevent d...

According to the World Health Organization, about 20% of adolescents may develop a depressive episode after age 15 if they are not the target of preventive intervention. In this study, we present the foundations, structure, main contents, and resources of a depression prevention and mental health promotion program aimed at 3rd-cycle adolescents: SMSyouth. The SMSyouth program is a structured group intervention ...

The contribution of ventilation on the energy performance of small residential ...

Efficient ventilation is an effective method for reducing thermal loads inside buildings, thus decreasing cooling energy consumption. This is especially relevant in warmer climates. Therefore, it is important to better understand the role that different ventilation parameters play on air-conditioning consumptions. This study analyzes the effect of three different ventilation parameters – air flow rate, minimum ...

Aktywność obywatelska młodzieżyi jej relacje z cechami osobowości– perspektywa ...

Celem prezentowanych badań jest analiza zależności między aktywnością obywatelską młodzieży a podstawowymi cechami osobowości. Badano trzy wymiary obywatelstwa, zgodnie z modelem Zalewskiej i Krzywosz-Rynkiewicz: (1) pasywne, (2) półaktywne i (3) aktywne – polityczne, społeczne, osobiste i zorientowane na zmiany. Podstawowe cechy osobowości badano w modelu Wielkiej Piątki (Costa, McCrae), który wyróżnia: (1) ot...

An equivalent self-adjusted heat capacity method for modelling heat diffusion p...

This work evaluates the thermal behaviour of a small aluminium-container-based thermal energy storage (TES) unit filled with a microencapsulated phase change material (PCM) – Micronal® DS 5001 X. ANSYS CFX® software is used for the 3D numerical simulations, which are based on the Effective Heat Capacity (EHC) method considering a purely diffusive transient model. In the formulation, a new artificial self-adjust...

Temperature regulation of polycrystalline silicon photovoltaic panels with mova...

This paper presents an experimental study to evaluate the improvement of photovoltaic (PV) performance through temperature regulation of a commercial polycrystalline silicon PV panel, by placing a movable thermal energy storage (TES) unit filled with a free-form commercial paraffin-based PCM (RT22HC) on the panel's back. The outdoor apparatus is located in Coimbra, Portugal (40.19N, 8.42W). Three identical PV p...

The importance of long-term hygrothermal assessment of museum spaces: method an...

This paper presents the analysis of the hygrothermal conditions of a museum space hosted in an 18th century building, in Coimbra (Portugal). This historical building, which houses the Science Museum of the University of Coimbra, is located in the historic centre of the University of Coimbra, officially declared a World Heritage Site in 2013 by UNESCO. The methodology proposed in EN 15757:2010 was applied to two...
