The Nevada Solar Energy-Water-Environment Nexus project collects a large amount of environmental data from a variety of sensors such as soil, atmosphere, biology, and ecology. Mostly, the environmental data is related to a development of renewable energy resources in the Nexus project. The environmental data can have an impact on other research fields if it can easily be shared with other researchers, students, teachers, and general users. Therefore, Nevada Climate Change Portal (NCCP) site was created for Nexus project with a purpose of sharing such data. However, there are some challenges to address in utilizing such data, collecting the data, and sharing the data among the users. In this research, the authors propose Extended Web Service Architecture for solving these challenges. The authors implement Arduino instead of CR1000 as a collector due to its cost effectiveness. The authors also use REST API to overcome the limitations of Arduino. Moreover, the authors experiment with popular Web-based data visualization tools such as Google Chart, Flex, OFC, and D3 to visualize NCCP data.

&lt;p&gt;As outliers in any data set may have detrimental effects on further scientific analysis, the measurement of any environmental parameter and the detection of outliers within these data are closely linked. However, outlier analysis is complicated, as the definition of an outlier is controversially discussed and thus - until now - vague. Nonetheless, multiple methods have been implemented to detect outliers in data sets. The application of these methods often requires some statistical know-how.&lt;/p&gt;&lt;p&gt;The present use case, developed as proof-of-concept implementation within the EOSC-Hub project, is dedicated to providing a user-friendly outlier analysis web-service via an open REST API processing environmental data either provided via Sensor Observation Service (SOS) or stored as data files in a cloud-based data repository. It is driven by an R-script performing the different operation steps consisting of data retrieval,&amp;#160; outlier analysis and final data export. To cope with the vague definition of an outlier, the outlier analysis step applies numerous statistical methods implemented in various R-packages.&lt;/p&gt;&lt;p&gt;The web-service encapsulates the R-script behind a REST API which is decribed by a dedicated OpenAPI specification defining two distinct access methods (i.e. SOS- and file-based) and the required parameters to run the R-script. This formal specification is subsequently used to automatically generate a server stub based on the Python FLASK framework which is customized to execute the R-script on the server whenever an appropriate web request arrives. The output is currently collected in a ZIP file which is returned after each successful web request. The service prototype is designed to be operated using generic resources provided by the European Open Science Cloud (EOSC) and the European Grid Initiative (EGI) in order to ensure sustainability and scalability.&lt;/p&gt;&lt;p&gt;Due to its user-friendliness and open availability, the presented web-service will facilitate access to standardized and scientifically-based outlier analysis methods not only for individual scientists but also for networks and research infrastructures like eLTER. It will thus contribute to the standardization of quality control procedures for data provision in distributed networks of data providers.&lt;/p&gt;&lt;p&gt;&amp;#160;&lt;/p&gt;&lt;p&gt;Keywords: quality assessment, outlier detection, web service, REST-API, eLTER, EOSC, EGI, EOSC-Hub&lt;/p&gt;

Data Mining and Data Warehousing are two most important techniques for pattern discovery and centralized data management in today’s technology. ELearning is one of the most significant applications of data mining. The main objective is to provide a proposal for a functional model and service architecture. The standards and system architecture are analyzed here. This paper gives importance to the integration of Web Services on the e-Learning application domain, because Web Service is the most advanced choice for distance education now. The process of e-Learning can be possible more effectively with the help of Web usage mining. More advanced tools are developed for online customer’s behaviour to increase sales, and profit, but no such tools are developed to understand learner’s behaviour in e-Learning. In this paper, some data mining techniques are discussed that could be used to enhance web-based learning environments.

Perjuangan University is developing an information system in its campus, but the system is partially built. This has resulted in its own problems, there is no connectivity between systems and the difficulty of developing data integration. So that in the business process that occurs many experience difficulties in data synchronization and the amount of duplicate data that must be entered. One solution to overcome this problem is to utilize web service technology. The web service architecture used is REST. REST as a bridge that is able to integrate data in a stateless format. The results of the application of the web service as a backend system are able to integrate the existing academic information systems and library information systems without changing existing structures, programs or architecture. Format data exchange between systems using the JSON format. In addition, officers do not need to input and verify data several times, when the data in the library information system changes automatically in the academic information system the changes are immediately read.

Academic Scores

There are still many elementary schools that have not implemented an information system for processing student grades online because of the assumption that this is still not needed, even though in fact the use of computerized information systems can help schools in improving the academic process to be more effective and efficient. Information systems with web-based applications that are now often found still have shortcomings, namely the mobility of their use is still lacking compared to Android-based applications which are now easier to use and access anywhere. The use of web applications as a means for teachers to input values as well as an android application as a means for parents to be able to monitor their children's academic scores is considered to be the most appropriate solution in implementing this information system, but differences in platforms between Android and the web make it difficult for data to be integrated with each other. Therefore we need an interoperability system in order to integrate applications from different platforms. Then an android based academic score monitoring application was made with RESTful web service. The selection of the RESTful web service system itself is because this system applies the concept of a client server where the server to be created is a web-based application that is used by the school to input student grades, and the client application is an android application intended for parents / guardians of students to get information regarding the value of his child. The output of this research is an application system for monitoring the academic scores of elementary school students by implementing the RESTful web service system in its application as well as the results of the application testing questionnaire based on the usability aspect of the application with the final result of the application eligibility percentage of 87%.Keywords: Monitoring Student Values, Platforms, Information Systems.
