Technical Project Status Display Information System

This paper presents the development of a one-page web application aimed at providing stakeholders with a succinct overview of ongoing projects and recently completed ones within a timeframe. Utilizing HTML, CSS, and JavaScript, along with contemporary web technologies, the application delivers an interface that is both user-friendly and informative[1]. By synchronizing data in real-time with project management tools and incorporating data visualization techniques, the application facilitates efficient access to and interpretation of project-related information for stakeholders. Emphasizing the importance of such a tool in fostering transparency, enhancing communication, and supporting decision-making in project management contexts, this paper also delves into technical implementation aspects, such as integration with project management APIs, design, and considerations for responsive design. This work contributes to advancing web-based solutions for project management, offering valuable insights into the creation of streamlined and accessible tools tailored to stakeholder requirements[2]. Key Words: stakeholder, project management, data visualization, decision-making, streamlined.

Developing and Evaluating Simplified Tools for Image Processing in a Problem-Based Learning Environment for Earth Observation

Earth observation is an interdisciplinary field of application. This makes it ideal for supporting natural science education in schools. Understanding satellite data can enable students to see more than just “beautiful images”. They can gain insights into an exciting field of application of many natural- and computer science fundamentals. In recent years, interactive lessons have been produced by our working group. They address the prospects and challenges connected with the teaching of earth observation topics in schools. The principles upon which the lessons are built promote a problem-based style of learning combined with a low impact in extraneous cognitive load for the students. Advances in web technology have made it necessary for interactive lessons to be redesigned and rethought. Contemporary web technologies have been selected and combined into an application framework to fulfill the requirements of our design principles and put a greater emphasis on usability during the content creation process. To allow offline usage of the learning modules it was tested whether this can be achieved using strictly client-side image processing. This article shows that, based on the technology stack used, lessons can be created that enable pupils to analyze remote sensing data in a much-simplified way. Using those simplified methods, a classification with an overall accuracy of 78.66% was achieved. The comparison of another simplified classification using just threshold values resulted in up to 89% probability to predict the outcome of a professionally produced dataset, making the simplified methods applicable in real-world examples presented in problem-based teaching scenarios.

The Virtual Theremin: Designing an Interactive Digital Music Instrument for Film Scene Scoring

Abstract This paper presents a first prototype of a virtual Theremin instrument for accompanying film scenes with sound. The virtual Theremin is implemented as a hybrid application for the web. Sound control is achieved by capturing user gestures with a webcam and mapping the gestures to the corresponding virtual Theremin parameters pitch and volume. Different sound types can be selected. The application’s underlying research is part of the multi-modal digital heritage project KOLLISIONEN which targets to open up the private archive of the Russian film maker Sergej Eisenstein to a broader public in digital form. Eisenstein, a film theorist and pioneer of film montage, was particularly intrigued by the Theremin as an instrument for film sound design. The virtual Theremin presented here is therefore linked to a film scene from the 1929 Soviet drama “The General Line” by Sergej Eisenstein which was never set to music originally. In its first implementation state, the application connects music interaction design with digital heritage in a modular, flexible and playful way and uses contemporary web technologies to enable easy operation and the greatest possible accessibility.

Web-based virtual reality for simulation of a heavy manipulator with a freely suspended payload

The paper presents the development of a Web-based Virtual Reality (VR) environment for simulation and visualization of the motion of a hydraulically driven heavy manipulator with a freely suspended payload. Two main problems are resolved in the paper. First, a combined mathematical model of the manipulator, considered as a 2 DOF discrete mechanical model is derived. It represents the dynamics of the two key functional subsystems of the manipulator – mechanical subsystem, consisting of a link and freely suspended payload and hydraulic subsystem, consisting of a hydraulic cylinder. Second, by the use of the contemporary Web technologies a VR environment for simulation, visualization and animation of the obtained results is developed. The produced VR environment is easy reused and shared with other users and thus considerably facilitates the design, investigation, and e-learning of such type of system.

The role of contemporary Web technologies in supply chain management

Ever changing market circumstances and globalization have caused electronic business (e-business) and supply chain management to integrate and virtual supply chains to emerge. E-business comprises all forms of business transactions and information sharing which is performed using information and communication technologies between companies, companies and their consumers, or companies and public administration. Supply chain is thus considered a unique and continuous business process, supported with goods and information flows throughout the entire distribution channel, where each company is part of the chain and boundaries between companies are non-existent. In times of economic uncertainty, cost reduction through rationalization and automatization of business processes, and improvement of productivity and quality of goods and services, become necessary for company's survival. In this context, the role of information and communication technologies in supply chain management is discussed, with particular attention to the contemporary web technologies such as extranet and Web 2.0.

AJAX in Development of Web-Based Architecture for Implementation of E-Governance

This article analyzes the diffusion of a Web technology named AJAX in facilitating e-government architecture and enhancing its potential by enablement of modern Web features as democracy and collaboration. Flexibility needed for free flow of interactive collaboration, compatibility, and robustness is treated as vital in the chapter. Major enterprises that have created landmarks in terms of participation of individuals and enterprises, along with contemporary Web technologies, are also analyzed to consolidate priority of technologies befitting robust and sustainable Web architecture. Emphasis is on the point that a proper collaboration among private, public, and government entities can only be achieved by proper information dissemination and acceptance of competent Web technologies, AJAX being one of them. Features of AJAX such as sectional processing ability, speed, bridging, portability, and compatibility are viewed with criticality for practical establishment.
