Turning Waste intoWealth: Sustainable Amorphous Silica from Moroccan Oil Shale Ash
Krime, Anas; Saoiabi, Sanaâ; Tlemcani, Mouhaydine; Saoiabi, Amed; Carreiro, Elisabete; Carrott, ManuelaMoroccan oil shale ash (MOSA) represents an underutilized industrial by-product, particularly in the Rif region, where its high mineral content has often led to its neglect in value-added applications. This study highlights the successful conversion of MOSA into amorphous mesoporous silica (AS-Si) using a sol–gel process assisted by polyethylene glycol (PEG-6000) as a soft template. The resulting AS-Si material...
DEVICE AND PROCESS FOR MASSIVE CAPTURE OF OLIVE FLIES - ELECTROCUTOR TRAP
Rei, Fernando; Gomes, Luis; Andrade, Leonardo; Tlemcani, Mouhaydine; Peça, José; Dias, AntónioThe present invention relates to the develop- ment of a device for capturing flying insects, in particular the olive fruit fly (Bactrocera oleae), for biological control of this olive grove pest. [0002] This device is autonomous and active in oper- ation and comprises a substantially cylindrically shaped outer body, as well as a fan and an insect-trapping mech- anism both placed inside such outer body, whereby ...
A portable measurement device based on phenanthroline complex for iron determin...
Fernandes, Samuel; Tlemcani, Mouhaydine; Bortoli, Daniele; Feliciano, Manuel; Lopes, Maria ElminaIn this work, a newly developed self-contained, portable, and compact iron measurement system (IMS) based on spectroscopy absorption for determination of Fe2+ in water is presented. One of the main goals of the IMS is to operate the device in the field as opposed to instruments commonly used exclusively in the laboratory. In addition, the system has been tuned to quantify iron concentrations in accordance with ...
Short-term solar radiation forecasting using a new seasonal clustering techniqu...
Tlemcani, Mouhaydine; Ali-Ou-Salah, Hamza; Oukarfi, BenyounesSolar radiation represents the most important parameter for sizing and planning solar power systems. However, solar radiation depends significantly on meteorological conditions which are variable and uncontrollable. Therefore, forecasting global solar radiation can play a key role to integrate solar energy resources into the electric grid. This paper presents a new hybrid approach based on seasonal clustering t...
Sensitivity analysis of atmospheric spectral irradiance model
Albino, Andre'; Bortoli, Daniele; Tlemcani, Mouhaydine; Hajjaji, Abdeloawahed; Joyce, AntónioMany Radiative Transfer Models (RTM) have been developed to simulate and estimate solar irradiance. Theirs accuracy is well documents in literature nonetheless the effect of the parameters uncertainties on the established models has not been well studied yet. This work focuses on implementing a RTM based on the models found in the literature along with some updates, with the aim to study the sensitivity of the ...
Sensitivity Analysis Through Error Function of Crystalline-Si Photovoltaic Cell...
Rashel, Masud Rana; Rifat, Jannatul; Goncalves, Teresa; Tlemcani, Mouhaydine; Melicio, RuiThe paper is based on the device representation of PV cell there are different internal parameters that representing their behavior. The internal parameters have impacts on the PV power generation. In this work, a single diode solar cell five parameter model is used to understand the internal parameters’ sensitivity not the efficiency. Sensitivity is important because of giving idea about parameters response to...
Modeling and Simulation of PV Panel Under Different Internal and Environmental ...
Rashel, Masud Rana; Melicio, Rui; Tlemcani, Mouhaydine; Goncalves, TeresaThis paper focuses on PV power conversion under different internal and environmental conditions with non-constant load, connected to a smart grid system. Due to environmental conditions, the PV system is a non-linear system and difficult to predict the power conversion. In the aspect of internal variables, it includes the five parameters of the single diode solar cell model identify their sensitivity through er...

Este instrumento - Environment simulator – permite fornecer dados ambientais necessários a simulação da radiação s...
Modelling and studies of the spectral response of some optoelectronic components
Albino, André; Bortoli, Daniele; Tlemcani, Mouhaydine; Joyce, AntónioSolar radiation takes in today's world, an increasing importance. Different devices are used to carry out spectral and integrated measurements of solar radiation. Thus the sensors can be divided into the fallow types: Calorimetric, Thermomechanical, Thermoelectric and Photoelectric. The first three categories are based on components converting the radiation to temperature (or heat) and then into electrical quan...
Tennis playing is associated to psychomotor speed in older drivers
Marmeleira, José; Melo, Filipe; Tlemcani, Mouhaydine; Fernandes, JorgeThe study investigated the association of tennis playing and running with the psychomotor speed of older drivers. Thirty-six active male drivers ( M age = 63.2 yr.) participated. A battery of four on-the road driving tests was performed by tennis players, runners, and a control group. Measures of simple and choice reaction time, movement time, and response time were collected under singleand dual-task condition...
