A 3-level 3-factor central composite design was used to optimize microwave-assisted Soxhlet extraction (MASE) to obtain maximum yield of target responses as a function of extraction time (t: 15–35 min), solvent composition ethanol:wather (C: 10–0%) and microwave power (P: 400–800 W). Maximum compounds of the three output parameters: 129,95 mg gallic acid equivalents/g dry weight TPC yield, 10,24 mg rutin equivalents/g dry weight TFC yield, and 76,95 mg gallic acid equivalents/g dry weight TTC, were obtained under optimum extraction conditions of t=35min, C=23%, and P=600W for the TPC and t=35 min, C=10%, and P=600W for the TFC and finally t=35min, C=22,8%, and P=600W for the TTC. For each experiment, the total polyphenolic contents, the total flavonoid contents and the total tannin contents were quantified using colorimetric essays. A significant effect of power extraction and solvent composition was proved by ANOVA. RSM applied in MASE, permitted to develop a solvent-minimized extraction process of polyphenols, flavonoids and tannins, using lower proportion of a green solvent with a shortest extraction time and in the same time to improve the quantity of extracts obtained from a natural resource.","PeriodicalId":360150,"journal":{"name":"2019 International Conference of Computer Science and Renewable Energies (ICCSRE)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127073242","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their objective is to provide road users with useful services such as safety, infotainment and traffic management, by integrating information and communication technology into vehicles and transport infrastructure. As a result, the design of an efficient VANET routing protocol is very important. Traditional architecture of the network impose particular communication solution implementation. This implementation often fail to fully support the constraints of VANET like topology dynamic changes. The cross-layer design paradigm was introduced as an alternative to develop more efficient and robust communication protocols.

Therefore, if one source vehicle does not have any gateway in its coverage, the proposed approach integrates an efficient relay selection scheme to select some vehicles equipped with IEEE 802.11p interface to act as relays in order to reach transmission range of mobile gateways.

It not only eliminates the large quantities of waste produced every day, but also generates the energy needed by a constantly changing population.The objective of this research work is to assess the household waste potential for electrical and thermal energy generation in Fez city (Morocco) using two modes of energy recovery: combustion and anaerobic digestion.The maximum electric generated was 228.04 GWh/year from direct combustion of household waste, whereas for thermal energy, a maximum value of 633.46 GWh/year in 2016. For anaerobic digestion, the maximum electric generated was 50.02 GWh/year and thermal energy generated was 75.79 GWh/year in 2016.","PeriodicalId":360150,"journal":{"name":"2019 International Conference of Computer Science and Renewable Energies (ICCSRE)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123706775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, knowing precisely the current versus voltage characteristics remains essential to perform the productivity as well as the solar efficiency of these devices. Researchers presented several methods, but the precise determination of the PV cell parameters remains a challenge. In this paper, we describe with rigorous way an analytical and simple method giving directly the expression of the photocurrent, the diode reverse saturation current, the shunt resistance, the series resistance and the ideality factor for a one exponential model. The three points usually used, at short circuit current, the maximum power and at open circuit, give four equations for the determination of unknown parameters. The fifth equation is at the point corresponding to half of the short circuit current. These equations are reduced to two nonlinear equations with two unknown parameters easily solved by the MathCAD software. The test of a polycrystalline Pv module is performed in a laboratory, the numerical values obtained give the best results compared to some previous methods and show a minimal error. A study about temperature effect on the all parameters was also made and shows a good conformity with the theoretical models, which proof the accuracy of the method.","PeriodicalId":360150,"journal":{"name":"2019 International Conference of Computer Science and Renewable Energies (ICCSRE)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114949573","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
