DSSCs are based on a semiconductor (i.e., TiO2), formed between a photo-sensitized anode and an electrolyte. In order to reach high conversion efficiency, it is important to increase the electron injection and optical absorption. One promising solution to increase the DSSCs efficiency is to decrease the wide band gap of TiO2 by doping a foreign ion into TiO2 structure. In the present work, Cu-doped TiO2 nanoparticles and thin films with different Cu:Ti rations are reported. The effect of dopant on photovoltaic performance of dye-sensitized solar cells were analyzed. The nanoparticles were synthesized via low temperature hydrolysis method, followed by thermal treatment at 773 K for 1 hr. X-ray diffraction and scanning electron microscopy (SEM) analyses revealed that the synthesized samples had uniform grains in nanometer scale. It was found that, 1.0wt.% Cu-doped TiO2 DSSC (C2) had the highest power conversion efficiency of 2.87%. This can be related to achievement of an optimum condition balance among the electron injection, dye-absorption and light scattering effect. The applied method exhibited superior potential for synthesis of Cu-doped TiO2 nanoparticles and films utilized as DSSCs.","PeriodicalId":416459,"journal":{"name":"Proceedings of the 3rd International Conference on Smart City Applications","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126123894","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}

In addition to their traditional role as creator and disseminator of knowledge, or incubator of innovations, they serve as models for exploring the use of information technologies in research and training whose information systems are part of it. Information systems (IS) have occupied a prominent place in all the universities in recent years and have become a lever for development and competitiveness. Universities currently have several information systems in their structures to evaluate and guide all missions in all its sectors of activity. These IS enable them to execute their management actions, write activity, forecast and share information among all their stakeholders. However, supporting users once a new information system is deployed is a very important part of the deployment process of this new tool. The purpose of this article is to demonstrate the usefulness of an intelligent tutoring system around university governance information systems, addressing an example of an intelligent tutoring system, designed for the effective use of two new government information systems of scientific research and academic cooperation of our university.","PeriodicalId":416459,"journal":{"name":"Proceedings of the 3rd International Conference on Smart City Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129504250","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}

Intrusions, attacks or anomalies in network infrastructures lead mostly in great financial losses, massive sensitive data leaks, thereby decreasing efficiency and the quality of productivity of an organization. Network Intrusion Detection System (NIDS) is an effective countermeasure and high-profile method to detect the unauthorized use of computer network and to provide the security for information. Thus, the presence of NIDS in an organization plays a vital part in attack mitigation, and it has become an integral part of a secure organization. In this paper, we propose to optimize a very popular soft computing tool widely used for intrusion detection namely Back Propagation Neural Network (BPNN) using a novel hybrid Framework (GASAA) based on Genetic Algorithm (GA) and Simulated Annealing Algorithm (SAA). Experimental results on KDD CUP' 99 dataset show that our optimized ANIDS (Anomaly NIDS) based BPNN, called \"ANIDS BPNN-GASAA\" outperforms the original ANIDS BPNN, ANIDS BPNN optimized by using only GA and several traditional and new techniques in terms of detection rate and false positive rate, and it is very much suitable for network anomaly detection.","PeriodicalId":416459,"journal":{"name":"Proceedings of the 3rd International Conference on Smart City Applications","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122478910","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}

The objective of this study is to promote the use of health mapping by focusing on the added value of this tool in the study of the spatial and temporal distribution of the incidence of parasitic disease including leishmaniasis, and to determine the relationship between this epidemic and altitude and draw up a health risk map for this plague in the prefecture of Meknes in central Morocco. To do this we have created a database containing the geographical parameters (the communes of the city), environmental (altitude), and sanitary (level of risk of leishmaniasis) through a field study on the cases of leishmaniasis declared at the level of the municipalities of the city of Meknes and using Qgis 2.18 software which is an open source software. We subsequently exploited the database created for thematic analyzes and the creation of thematic maps with a focus on causal links connecting the geographical and environmental factors, This study shows that spatial representation and spatial analysis of impacts is an important tool in identifying risk locations. This spatial representation known as the risk map is essential in the careful identification of high-risk municipalities. Indeed, a risk map is a geographical profile of the incidence that indicates the areas where it is concentrated.","PeriodicalId":416459,"journal":{"name":"Proceedings of the 3rd International Conference on Smart City Applications","volume":"126 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133440731","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}
