Investigain: A Productive Asset Management Web Application

The Investigain is a progressive web application to make mutual funds investments through a Systematic Investment Plan. The application utilizes the web’s modern capabilities, such as Asynchronous JavaScript and XML (AJAX), JavaScript, and Hypertext Marker Language (HTML5). The application also uses a powerful relational database management system, such as MySQL, to display asset management information. The application has two portals, one for investors and one for a particular asset manager or asset management company. Each investor has an account in the investor portal. The investor can view his/her profile, current balance, balance history, dividends, the units of mutual funds bought, unit price, the value of each mutual fund, and can pay installments using an embedded online payment gateway. Asset managers can monitor all investments, manage user accounts, and reimburse dividends using the admin portal. This paper also presents the experimental results of using the Investigain application, compares them with existing systems, and details the application’s prospect to improve its socio-economic conditions. The system’s frontend is designed with Bootstrap and jQuery frameworks. The backend is designed using Hypertext Preprocessor (PHP) server-side scripting language. The system demonstrated increased satisfaction from its clients.

CREATING STYLE SHEET BY USING SPEECH RECOGNITION

Today’s rich Web applications use a mix of Java Script and Asynchronous communication with the application server. This mechanism is also known as Ajax: Asynchronous JavaScript and XML. The intent of Ajax is to exchange small pieces of data between the browser and the application server, and in doing so, use partial page refresh instead of reloading the entire Web page. AJAX (Asynchronous JavaScript and XML.) is a powerful web development model for browser-based Web applications. This project is designed and developed keeping that factor into mind, and a little effort is made to achieve this aim. Our project is capable to recognize the speech and convert the input audio into text & style sheet it also enables a user to perform operations “save, open, exit” a file by providing voice input.

Real-time monitoring using AJAX and WebSockets

The primary method for facilitating asynchronous communication over the Web is asynchronous JavaScript and XML (AJAX). Although AJAX provides the Web with warranted real-time functionality, unconventional techniques of programming are required at the cost of extensive use of resources. Implementing asynchronous communication over the Web, WebSockets, which is an emerging protocol, has the potential to address many challenges. There has been no independent study analyzing AJAX and WebSockets quantitatively. This paper, therefore, provides the following contributions to integrating Web technologies in realtime systems. First, it quantitatively compares AJAX and Websocket performance in terms of connection time by varying the number of requests over the web. Second, it compares the data bytes transferred by varying the number of requests. Third, it quantitatively compares network bandwidth consumption between AJAX and WebSocket

Mutual Browser Conflicts Disclosure

In today’s world everything is becoming web dependent, and due to the advances made in web technologies, web developers have to face various challenges. Every web application before being deployed goes through various phases which may look different on different browsers. It becomes difficult to identify correct web page when it gives differences across different browsers. The web pages may give significant differences and it is known as cross-browser inconsistency. A technology that has gained a prominent position known as AJAX (Asynchronous JavaScript and XML), in which the combination of JavaScript and Document Object Model (DOM) manipulation, along with asynchronous server communication is used to achieve a high level of user interactivity. With this change in developing web applications comes a whole set of new challenges, One way to address these challenges is through the use of a crawler that can automatically walk through different states of a highly dynamic AJAX site and create a model of the navigational paths and states. Identifying these conflicts manually is a laborious task. Mutual browser conflict disclosure presents a mechanism to identify conflicts.

Online community collaborative map: A geospatial and data visualization tool for cancer data.

The aim of this study was to develop an online collaborative map to enable researchers to locate, explore, and share cancer data.This 2-scale (global and country-level) cancer map adopts a database-driven model, which was implemented using the Google Map Application Programming Interface (API) and asynchronous JavaScript and XML (AJAX) technology. Seven visualization techniques were used to present data. Data on worldwide cancer mortality between 1950 and 2013 were taken from the International Agency for Research on Cancer (IARC) database. Incidence data were from the IARC CI5plus database. Survival data were from the IARC SURVCAN study. Prevalence data between 1990 and 2017 were from the Institute for Health Metrics and Evaluation's (IHME) catalog while demographic data were from the World Bank Data Catalog. Cancer data for Taiwan between 1991 and 2016 were obtained from the Department of Health and Welfare. This study used visualization techniques that included: a choropleth map to display the prevalence of cancer; a tornado diagram to show the age-standardized mortality rates of all cancers among men and women in 2013; a treemap to show a ranking of cancer mortality data; a sunburst chart to show mortality rates of all cancers by gender; a line chart to show mortality trends for all cancers; a bar chart to show mortality and incidence rates and a heatmap to show variations in cancer across different countries.The world cancer map generated by this study can be accessed at http://worldmap.csmu-liawyp.tw. Country-level mortality data are presented as crude and age-standardized rates.We used visualization methodologies and constructed an easily maintainable web-based user interface with cancer data from administrative regions in 150 countries. This serves as a platform that allows researchers to manage and disseminate cancer data.

JavaScript Object Notation (JSON) data serialization for IFC schema in web-based BIM data exchange

Abstract In the building industry, building data such as objects and processes are described in Industry Foundation Classes (IFC) data model schema to support a neutral data exchange format for BIM tools interoperability. While IFC specification has been encoded in ifcXML format by buildingSMART to support XML-based data transmission, there is a lack of studies on the implementation of IFC specification using JavaScript Object Notation (JSON) serialization. JSON is a key-value style lightweight data exchange format that has higher parsing efficiency than XML and due to the inadequacies of XML, JSON has been widely used in Web applications, specifically in Asynchronous JavaScript and XML (AJAX) Web services. This paper highlights the need for JSON implementation of IFC specification and introduces ifcJSON Schema and its data content. The main objective of this study is to outline how IFC specification can be represented in JSON format. Therefore, the study explains the implementation of the IFC standard as a JSON schema to guide the creation of JSON documents. The ifcJSON documents can be used for web-based data transfer as an alternative to XML documents. Since current IFC specification release is IFC4 Add1, the implementation of ifcJSON4 schema is specified and guidelines for generating and validating ifcJSON documents are described. Additionally, this paper implements ifcJSON4 schema in a use case within the precast concrete domain by indicating the data content for a precast building element with its corresponding geometry representation, product placement, and owner history data. The analysis of results indicates that ifcJSON4 schema developed in this paper is a valid JSON schema that can guide the creation of valid ifcJSON documents to be used for web-based data transfer and to improve interoperability of Cloud-based BIM applications.

One-Page Multimedia Interactive Map

The relevance of local knowledge in cultural heritage is by now acknowledged. It helps to determine many community-based projects by identifying the material to be digitally maintained in multimedia collections provided by communities of volunteers, rather than for-profit businesses or government entities. Considering that the search and browsing of texts, images, video, and 3D models related to places is more essential than using a simple text-based search, an interactive multimedia map was implemented in this study. The map, which is loaded on a single HyperText Markup Language (HTML) page using AJAX (Asynchronous JavaScript and XML), with a client-side control mechanism utilising jQuery components that are both freely available and ad-hoc developed, is updated according to user interaction. To simplify the publication of geo-referenced information, the application stores all the data in a Geographic JavaScript Object Notation (GeoJSON) file rather than in a database. The multimedia contents—associated with the selected Points of Interest (PoIs)—can be selected through text search and list browsing as well as by viewing their previews one by one in a sequence all together in a scrolling window (respectively: “Table”, “Folder”, and “Tile” functions). PoIs—visualised on the map with multi-shape markers using a set of unambiguous colours—can be filtered through their categories and types, accessibility status and timeline, thus improving the system usability. The map functions are illustrated using data collected in a Comenius project. Notes on the application software and architecture are also presented in this paper.

Public health mapping and Geographical Information Systems (GIS) are already being used to locate the geographical spread of diseases. This study describes the construction of an easy-to-use online atlas of cancer mortality (1972–2011) and incidence (1995–2008) in Taiwan.Two sets of color maps were made based on “age-adjusted mortality by rate” and “age-adjusted mortality by rank.” AJAX (Asynchronous JavaScript and XML), JSON (JavaScript Object Notation), and SVG (Scaling Vector Graphic) were used to create the online atlas. Spatio-temporal patterns of cancer mortality and incidence in Taiwan over the period from 1972 to 2011 and from 1995 to 2008.The constructed online atlas contains information on cancer mortality and incidence (http://taiwancancermap.csmu-liawyp.tw/). The common GIS functions include zoom and pan and identity tools. Users can easily customize the maps to explore the spatio-temporal trends of cancer mortality and incidence using different devices (such as personal computers, mobile phone, or pad). This study suggests an easy- to-use, low-cost, and independent platform for exploring cancer incidence and mortality. It is expected to serve as a reference tool for cancer prevention and risk assessment.This online atlas is a cheap and fast tool that integrates various cancer maps. Therefore, it can serve as a powerful tool that allows users to examine and compare spatio-temporal patterns of various maps. Furthermore, it is an-easy-to use tool for updating data and assessing risk factors of cancer in Taiwan.

공간정보 오픈플랫폼 설계를 위한 2D Web Mapping Open API 비교 연구

Google 지도는 AJAX(Asynchronous JavaScript and XML) 기술을 이용하여 Web-GIS의 반응 속도를 크게 변화시켰다. 또한 Google은 Open API(Application Programming Interface)인 Google Maps API를 공개하여 기존의 SDK(Software Development Kit)와 ASP(Application Service Provider)가 주도하던 지도 시장에 Open API라는 패러다임의 변화를 가져왔다. 이후, 많은 정부와 기업과 오픈소스 진영에서 비슷한 방식의 Open API를 내놓았으며 Web-GIS 시장을 키워왔다. 또한 HTML5 표준에 대한 최신 웹브라우저의 적극적인 표준 구현으로 인해 웹지도는 단순한 웹페이지가 아닌 하나의 웹어플리케이션으로 진화하여 속도와 성능향상을 이루었다. 하지만 많은 공간정보 2D Open API들이 나왔지만 국내의 API에 대한 현실적인 비교분석은 잘 이루어지지 않은 실정이다. 따라서 본 논문에서는 먼저 공간정보 2D Open API를 이루고 있는 구성요소들을 살펴보고, 각각의 API들이 어떠한 기능들을 얼마만큼 지원하는지를 살펴보고자 한다. 또한 각 API 별로 기능적인 특징과 서비스적인 특징들을 살펴보고 비교분석을 수행하고자 한다. 끝으로, 공간정보 2D Open API의 서비스 사례들을 살펴보고 앞으로의 발전 방향에 대해 제시하고자 한다. Google Maps have changed the response time of Web-GIS using AJAX technologies. In addition, Google released the Open API named Google Maps API(Application Programming Interface) and it lead to the big paradigm on the Open API, where the SDK(Software Development Kit) and ASP(Application Service Provider) had ruled at the related map market. In short, the Open API has been paradigm-shifting for the web mapping. After this, government, many companies and open source foundations have guided Web-GIS market's growth through releasing the relevant Open APIs. So many comparative analysis on web-mapping API carried out by many researches. However there were no researches that can be applied to our current domestic environments. This paper investigates components of web-mapping API. Then we compare how many components supported and enumerate features for each of those APIs. Finally this paper presents direction of future development of Web Mapping API.

Automatic Testing of AJAX Applications through Dynamic Analysis of User Interface State Change

The growing popularity and importance of web applications have been increasing continuously in recent years. Use of JAVASCRIPT and dynamic DOM (Document Object Model) manipulation on the client side of web applications is becoming a widespread approach for achieving rich interactivity and responsiveness in modern web applications. AJAX (Asynchronous JAVASCRIPT and XML) based web applications rely on asynchronous client-server communication and client-side runtime manipulation of the DOM tree. This not only makes them fundamentally different from traditional web applications but also make them more error prone and harder to test. The proposed method for testing automatically AJAX application is based on a crawler to infer a state-flow graph for all client-side user interface states of an AJAX application. Focus is on obtaining a model by “crawling” an AJAX application, automatically clicking buttons and other user interface elements. In order to recognize failures in executions, use of invariants are proposed [1]. These invariants can be generic (e.g., after any client-side change the DOM should remain W3C-compliant valid HTML) or application-specific (e.g., the home-button in any state should lead back to the starting state). General Terms AJAX, JAVASCRIPT, XML, DOM

Dcs Data Viewer, an Application that Accesses ATLAS DCS Historical Data

The ATLAS experiment at CERN is one of the four Large Hadron Collider experiments. The Detector Control System (DCS) of ATLAS is responsible for the supervision of the detector equipment, the reading of operational parameters, the propagation of the alarms and the archiving of important operational data in a relational database (DB). DCS Data Viewer (DDV) is an application that provides access to the ATLAS DCS historical data through a web interface. Its design is structured using a client-server architecture. The pythonic server connects to the DB and fetches the data by using optimized SQL requests. It communicates with the outside world, by accepting HTTP requests and it can be used stand alone. The client is an AJAX (Asynchronous JavaScript and XML) interactive web application developed under the Google Web Toolkit (GWT) framework. Its web interface is user friendly, platform and browser independent. The selection of metadata is done via a column-tree view or with a powerful search engine. The final visualization of the data is done using java applets or java script applications as plugins. The default output is a value-over-time chart, but other types of outputs like tables, ascii or ROOT files are supported too. Excessive access or malicious use of the database is prevented by a dedicated protection mechanism, allowing the exposure of the tool to hundreds of inexperienced users. The current configuration of the client and of the outputs can be saved in an XML file. Protection against web security attacks is foreseen and authentication constrains have been taken into account, allowing the exposure of the tool to hundreds of users world wide. Due to its flexible interface and its generic and modular approach, DDV could be easily used for other experiment control systems.

A new web-based tool for data visualization in MDSplus

The Java tool jScope has been widely used for years to display acquired waveform in MDSplus. The choice of the Java programming language for its implementation has been successful for several reasons among which the fact that Java supports a multiplatform environment and it is well suited for graphics and the management of network communication. jScope can be used both as a local and remote application. In the latter case, data are acquired via TCP/IP communication using the mdsip protocol. Exporting data in this way however introduces several security problems due to the necessity of opening firewall holes for the user ports. For this reason, and also due to the fact that JavaScript is becoming a widely used language for web applications, a new tool written in JavaScript and called WebScope has been developed for the visualization of MDSplus data in web browsers.Data communication is now achieved via http protocol using Asynchronous JavaScript and XML (AJAX) technology. At the server side, data access is carried out by a Python module that interacts with the web server via Web Server Gateway Interface (WSGI).When a data item, described by an MDSplus expression, is requested by the web browser for visualization, it is returned as a binary message and then handled by callback JavaScript functions activated by the web browser.Scalable Vector Graphics (SVG) technology is used to handle graphics within the web browser and to carry out the same interactive data visualization provided by jScope. In addition to mouse events, touch events are supported to provide interactivity also on touch screens. In this way, waveforms can be displayed and manipulated on tablet and smartphone devices.

BBProF: An Asynchronous Application Server for Rapid Identification of Proteins Associated with Bacterial Bioleaching

Recovery of metal value, especially from low-grade ores and overburden minerals using acidophilic bacteria through the process of bioleaching is an environmentally benign and commercially scalable biotechnology. In recent years, while the “OMICS” landscape has been witnessing extensive application of computational tools to understand and interpret global biological sequence data, a dedicated bioinformatic server for analysis of bacterial information in the context of its bioleaching ability is not available. We have developed an on-line Bacterial Bioleaching Protein Finder (BBProF) System, which rapidly identifies novel proteins involved in a bacterial bioleaching process and also performs phylogenetic analysis of 16S rRNA genes. BBProF uses the features of Asynchronous Java Script and XML (AJAX) to provide an efficient and fast user experience with minimal requirement of network bandwidth. In the input module the server accepts any bacterial or archaeal complete genome sequence in RAW format and provides a list of proteins involved in the microbial leaching process. BBProF web server is integrated with the European Bioinformatics Institute (EBI) web services such as BLAST for homology search and InterProScan for functional characterization of output protein sequences. Studying evolutionary relationship of bacterial strains of interest using Muscle and ClustalW2 phylogeny web services from EBI is another key feature of our server, where 16S rRNA gene sequences are considered as input through a JQUERY interface along with the sequences present in the BBProF database library. Complete genome sequences of 24 bioleaching microorganism characterized by genomic and physiological study in the laboratory and their respective 16S rRNA gene sequences were stored in the database of the BBProF library. To our knowledge BBProF is the first integrated bioinformatic web server that demonstrates its utility in identifying potential bioleaching bacteria. We hope that the server facilitate ongoing comparative genomic studies on of bioleaching microorganisms and also assist in identification and design of novel microbial consortia that are optimally efficient bioleaching agents.

Distributed OSN Crawling System based on Ajax Simulation

In the age of Web2.0, lots of online social networks (OSNs) like Facebook, Twitter, WeiBo become the most popular information transform platform, which catch more and more attention from Information Retrieval (IR). However, traditional web crawling System get into trouble because of the complicated OSN web pages, the rapid message exploding and the heavy using of Asynchronous JavaScript and XML(AJAX). We design and implement a distributed system based on Message Oriented Middleware (MOM) and Ajax simulation, which crawls 70 millions of Twitter detail items in one month. The data Acquisition shows that the crawling with Ajax simulation is able to get items loaded by Ajax without limitations, the distributed system based on MOM and Ajax simulation is able to crawl massive OSN data completely, quickly, frequently and unrestrictedly.

Geographic Stereo Video Web Services: Framework Design and Interface Development

The traditional multimedia map,which combines map and multimedia elements,represents the geographic world more visually.With the rapid advance of the multimedia and position technology,the new-style geo-tagged media,such as geographic video,panoramic picture and measurable image,have been introduced in GIS applications.This paper aims to introduce the stereo video to GIS.Geographic stereo video includes both spatial and temporal geographic characteristics acquired through ground-based or non-ground-based cameras.It is the stereo video that extends the elements of interior and exterior orientation for video frame.Therefore,it supports the video retrieval and image measurement based on the spatial information,And it has been a new way for geographic representation.With the wide application of web service technology,geographic stereo video web service will further expand the video GIS application.To fully utilize the geographic stereo video resource in web environment,this paper aims to design a framework of geographic stereo video web services and to develop the related RESTful web interfaces.Based on the discussion of functional requirements such as visualization,querying and measurement,a web service framework composed of data layer,service layer and presentation layer for geographic stereo videos is introduced.All functions are packaged as a service in this framework and its communication are based on a unified interface,standard protocol and universal data format.The video URI resources,its representation format and related operation interfaces are defined carefully as the RESTful web services.The client-server interaction mechanisms for video querying,video displaying and image measurement are outlined in details.All the geographic stereo video web services are implemented on the basis of Windows Communication Foundation(WCF) and ArcGIS Server technologies.Based on the geographic stereo video service and browser-side AJAX(Asynchronous JavaScript and XML) programming,a prototype system of geographic stereo video web service for Henan University(Jinming campus) was developed.The prototype application shows that the service framework and system design introduced in this paper is feasible and adequate for video GIS application development.It is of reference value for web service standardization of new-style geo-tagged media.

AJAX를 이용한 태양광 인버터의 모니터링 시스템 구현

본 논문에서는 AJAX(Asynchronous JavaScript And XML)를 이용하여 태양광 인버터의 모니터링 시스템을 구현하고자 한다. AJAX는 DHTML(Dynamic Hyper Text Makeup Language)과 다른 자바스크립트 기술 등과 함께 RIA(Rich Internet Application)를 만들 수 있는 기술 중 하나이다. 이를 사용하여 일반 응용프로그램에 필적하는 강력한 응용프로그램을 만들 수 있다. 기존의 데이터 처리 기법으로는 동일 페이지에서 데이터의 Request와 Response를 동적으로 처리할 수 없다. 하지만 비동기 통신 방법인 AJAX 기반 기술을 이용하면 직관적이며 데이터 변동 상태를 실시간으로 제공하기 때문에, 한 페이지 내에서 모든 기능을 실행할 수 있고 페이지 전환 없이 데이터 전송량이 현저히 작은 AJAX를 사용하여 효율적인 관리 및 모니터링 할 수 있기 때문에 태양광 인버터모니터링 시스템에 AJAX를 적용하여 효율적인 모니터링 시스템을 구현하였다. In this paper, the Solar Inverter will be monitored by using the AJAX(Asynchronous JavaScript and XML). AJAX is the one of the technologies that can make the RIA(Rich Internet Application) with DHTML(Dynamic Hyper Text Makeup Language) and other java script technology. By using this, a strong application program that is comparable to the general application program can be made. With an existing data-processing technique, the request and response of data can't be processed dynamically on the same page. However, real-time monitoring of data and operation statuses can be confirmed by using the AJAX an asynchronous method of communication. Also without changing the page, the amount of data transmission used the AJAX with significantly small amounts of data to build a Solar Inverter monitoring system that is able to efficiently handle management and monitoring, operating all functions within one page.

A Hierarchical Signal-Space Partitioning Technique for Indoor Positioning with WLAN to Support Location-Awareness in Mobile Map Services

The precise and accurate performance of location estimation is a vital component of context-aware applications. Numerous mobile devices with built-in IEEE 802.11 Wi-Fi technology can be used to estimate a user's location through a wireless local area network (WLAN) in indoor environments in which fixed access points are deployed. This study deals with improving the common techniques of such positioning once the acquisition of the fingerprint database in offline phase is performed. The main idea is to propose a methodology that includes two layers of classification: a concurrent hierarchical partitioning of both signal and physical space in a way that signal patterns in each part of building have the highest similarity, and a precise and independent positioning in a given part. A procedure for combining the proposed classifier with either artificial neural network (ANN) or Bayesian probabilistic model is then introduced. We also consider an alternative strategy for ANN learning by including all raw observations. The average distance error was successfully reduced in the proposed methodology by 32 % compared to the simple approach. We concluded that the physical partitioning should also consider the signal behavior. Toosi location-aware mobile system was ultimately implemented, providing different services (e.g., friend finder and nearest point of interest) based on the proposed technique via WLAN. The system benefits from the high level of interaction provided by Asynchronous JavaScript and XML (AJAX) technology. It is capable of transferring locational data and GIS map services efficiently to the mobile terminal.
