Ship shore power technology is an effective means to achieve energy conservation and emission reduction for water transportation. In order to ensure the scientific usage of ship shore power and ...optimize the layout of ship shore power piles, a ship shore power data analysis system based on the Doris data warehouse technology is designed and implemented. This system can realize a real-time data statistics and query based on Doris. It realizes the visual display based on the back-end and front-end separation technology. The front-end requests data through Axios, and the back-end returns the query data with the JSON format. Maps and charts are displayed based on the Echarts and Mapbox tools. The system has been applied in the maritime supervision, and provided the data support for the decision-making of ship shore power management.

Objective: Predict the total traffic count of streaming data in various routes to reduce traffic congestion and informing public about current traffic condition by displaying it in dashboard. ...Analysis: Real-time traffic monitoring can be made with the help of sensor connected devices, it generates huge volume and high speed data, Apache Kafka and Spark streaming engine is used for Processing these data. Findings: In existing system Traffic is predicted by deploying sensors in traffic signal lane and Apache hadoop used for processing data, it is batch processing system takes more time to process the data. In Proposed system total count of traffic predicted by using connected vehicles and Apache spark is used for processing live streaming data, by using spring boot total count of traffic is displayed in dashboard. Improvement: Real-time traffic prediction is done with live streaming data, Apache spark process data in-memory and dashboard updated for every five seconds.

Mobilna tehnologija je sa svojim mogućnostima iz temelja promijenila način života ljudi i način međusobne komunikacije. S razvojem mobilne tehnologije i interneta, mobilne aplikacije postale su sve ...popularnije, omogućujući korisnicima lakšu komunikaciju i dijeljenje podataka. Već desetak godina, upravo primjena tahvih tehnologija rezultiralo je pojavom različitih pametnih rješenja..
Pametni grad (engl. Smart city) danas je pojam koji povezuje primjenu suvremenih IT rješenja za potrebe gradova. Upravo je HRcity mobilna aplikacija i sustav koji omogućuje svakom gradu da postane „pametan“. Aplikacija svojim implementiranim modulima omogućuje gradovima primjenu mobilnih tehnologija u različitim segmentima njihovoga djelovanja. Segmentima kao što je zbrinjavanje otpada, rad dječjih vrtića, kontrola kvalitete okoline, komunalne djelatnosti i slično. U radu je prikazana struktura mobilne aplikacije i način njenoga rada. Tehnologije koje su korištene u njenoj implementaciji te strategija koja je korištena u uvođenju ove aplikacije.
The "IamOK" online health status reporting system is developed to meet the needs of colleges and universities to grasp the health status of teachers and students during the Covid-19 epidemic ...prevention and control period. The development and design framework of the system is elaborated by requirements analysis and overall structure design, followed by the introduction of the development method of using JPA, Redis caching technology, Nginx and other key technologies under the Spring Boot framework.
In the era of continuous technological development, which is followed by the increase in the speed of computers and the Internet, it is also important to develop techniques and programming languages ...as well as various mechanisms helping programmers in their work. Therefore, the frameworks were created, or skeleton applications that define the application structure and the general mechanism of its operation, to facilitate writing programs and unify the structure of various applications. The purpose of this article is to analyze and compare the performance of two popular frameworks, used to create a server part of a web application in Java, namely the Spring Framework and Play Framework.
Web application technologies are growing rapidly with continuous innovation and improvements. This paper focuses on the popular Spring Boot 1 java-based framework for building web and enterprise ...applications and how it provides the flexibility for service-oriented architecture (SOA). One challenge with any Spring-based applications is its level of complexity with configurations. Spring Boot makes it easy to create and deploy stand-alone, production-grade Spring applications with very little Spring configuration. Example, if we consider Spring Model-View-Controller (MVC) framework 2, we need to configure dispatcher servlet, web jars, a view resolver, and component scan among other things. To solve this, Spring Boot provides several Auto Configuration options to setup the application with any needed dependencies. Another challenge is to identify the framework dependencies and associated library versions required to develop a web application. Spring Boot offers simpler dependency management by using a comprehensive, but flexible, framework and the associated libraries in one single dependency, which provides all the Spring related technology that you need for starter projects as compared to CRUD web applications. This framework provides a range of additional features that are common across many projects such as embedded server, security, metrics, health checks, and externalized configuration. Web applications are generally packaged as war and deployed to a web server, but Spring Boot application can be packaged either as war or jar file, which allows to run the application without the need to install and/or configure on the application server. In this paper, we discuss how Atmospheric Radiation Measurement (ARM) Data Center (ADC) at Oak Ridge National Laboratory, is using Spring Boot to create a SOA based REST 4 service API, that bridges the gap between frontend user interfaces and backend database. Using this REST service API, ARM scientists are now able to submit reports via a user form or a command line interface, which captures the same data quality or other important information about ARM data.
In the world of the Internet where people are consuming web-content, more and more emphasis is placed on user friendliness of web-pages. It means increasing web-page usability and better ...user-experience. Increasing quality of user-experience (UX) is the task of UX developers. They should always base their work on the best practices and research. Each webpage has its own specificity and it leads to new challenges for the UX developers. One of the biggest issues is the problematic view of a web-page on specific devices with specific web-browser versions. Tools for capturing user behaviour are available, but there are issues with data ownership and with the development of new functionality. Actually, there are no free easily scalable and extendable products for user data gathering on the market. In this paper, implementation of architecture (based on Spring Boot microservices) for capturing web user behaviours with feedback propagation is introduced. Architecture implementation is easily scalable and extendable. All of the components are described in detail. At the end of this paper, summary and limitation of created architecture is discussed. Webalyt is helpful for understanding user behaviour and improving user-experience.

This demo showcases some of the capabilities of Diligent, a platform for collecting and analysing data from Online Social Networks and is still under development. Diligent relies on microservices and ...reactive streams, which optimize the time spent (t), to the resources used (r), ratio (t/r). The proposed demo will present: - The vast hardware utilization margins produced by using both blocking and reactive I/O approaches. - The performance gap between using blocking I/O and Reactive I/O clients. Both experiments highlight the added benefits of using reactive approaches in online social network data processing systems.
