BANΔIT: B’‐factor Analysis for Drug Design and Structural Biology
2020
The analysis of B‐factor profiles from X‐ray protein structures can be utilized for structure‐based drug design since protein mobility changes have been associated with the quality of protein‐ligand interactions. With the BANΔIT (B’‐factor analysis and ΔB’ interpretation toolkit), we have developed a JavaScript‐based browser application that provides a graphical user interface for the normalization and analysis of B’‐factor profiles. To emphasize the usability for rational drug design applications, we have analyzed a selection of crystallographic protein‐ligand complexes and have given exemplary conclusions for further drug optimization including the development of a B’‐factor‐supported pha…
GYROCOMPU: Toolbox Designed for the Analysis of Gyrotron Resonators
2020
The key point of gyrotron design is the analysis of the radio frequency (RF) behavior in gyrotron resonators. This article proposes a comprehensive, user-friendly and effective gyrotron design toolbox (GYROCOMPU) based on the MATLAB platform. GYROCOMPU associates a relatively complete set of codes for gyrotron analysis and integrates them together into a graphical user interface (GUI). The solving algorithm of the cold cavity equations and self-consistent equations is improved. The solving method improvement in these calculation algorithms renders the analysis more efficient and accurate. Three typical examples of gyrotrons working in the 140-GHz TE03 mode, 42-GHz TE03 mode, and 140-GHz TE1…
A Web Application for the Remote Control of Multiple Unmanned Aerial Vehicles
2019
Unmanned Aerial Vehicles (UAVs) are receiving an increasing attention from the research and industry community, and today they are adopted for several civilian and military applications. However, state of the art technologies are still based on a single UAV either directly controlled by the human operator or supervised through the manual definition of a flight plan. As a result, scalability is still a significant limitation for such systems, especially when large areas need to be monitored. In this paper we propose a web based application for the control of multiple UAVs. The application has three layers. The first layer allows the user to remotely submit a monitoring mission through a web …
Interactive multiobjective optimization system WWW-NIMBUS on the Internet
2000
Abstract NIMBUS is a multiobjective optimization method capable of solving nondifferentiable and nonconvex problems. We describe the NIMBUS algorithm and its implementation WWW-NIMBUS. To our knowledge WWW-NIMBUS is the first interactive multiobjective optimization system on the Internet. The main principles of its implementation are centralized computing and a distributed interface. Typically, the delivery and update of any software is problematic. Limited computer capacity may also be a problem. Via the Internet, there is only one version of the software to be updated and any client computer has the capabilities of a server computer. Further, the World-Wide Web (WWW) provides a graphical …
A visual framework to create photorealistic retinal vessels for diagnosis purposes
2020
The methods developed in recent years for synthesising an ocular fundus can be been divided into two main categories. The first category of methods involves the development of an anatomical model of the eye, where artificial images are generated using appropriate parameters for modelling the vascular networks and fundus. The second type of method has been made possible by the development of deep learning techniques and improvements in the performance of hardware (especially graphics cards equipped with a large number of cores). The methodology proposed here to produce high-resolution synthetic fundus images is intended to be an alternative to the increasingly widespread use of generative ad…
Dynamic interface for machine vision systems
2002
Iconic programming intends to provide expressive tools to implement, to debug, and to execute programs. For this purpose, visual languages need pictorial constructs and metaphors to guide the design of algorithms in interactive fashion. In the paper a new class of dynamic visual interfaces, named DIVA (Dynamic Interface for Visual Applications), is introduced, its properties are described, and an application to visual compilers in a multi-processors system dedicated to image analysis is given. Moreover, a formal definition of dynamic icon (DI) is also given.
Assessment of tools for urban energy planning
2019
Abstract In recent years, studies and policies have encouraged the diffusion of distributed energy supply technologies and large integration of renewable sources. This increases the need for new professionals in energy planning. Several computational tools for energy planning have been developed as described in the technical literature. However, energy planners of urban/district areas engaged in the transition towards smart systems related to buildings energy services require well-documented tools to evaluate the combination of available energy sources by proper conversion technologies. With this, after a scientific review, we selected 17 tools targeted on an urban/districts scale that can …
Usability challenges in digital learning solutions
2015
Usability is a key element in successful software. Ensuring the technical usability of a learning solution enables users to focus on their main task, learning. The purpose of this paper is to demonstrate the results of heuristic usability evaluations of digital learning solutions. Heuristic evaluations were conducted on 24 digital learning solutions from one country (Finland) and two country groups (Asian countries and Spanish speaking countries) concentrating on the usability of the user interface of each evaluated solution. The main results of this study indicate that a few heuristics cover the majority of all usability problems (UPs) observed in learning solutions, but these heuristics c…
Are requirements elicitation sessions influenced by participants' gender? An empirical experiment
2021
[EN] Context: Requirements elicitation is a crucial phase in the software development life cycle. During requirements elicitation sessions, requirements engineers capture software requirements, and motivate stakeholders to express needs and expected software functionalities. In this context, there is a lack of extensive empirical research reporting the extent to which elicitation sessions can be influenced by participants' gender. Objective: This paper presents our research endeavour to investigate requirements engineers' effort and elicited requirements' accuracy based on participants' gender. Method: We conducted an experiment in two rounds with a total of 59 students who played the role …
Co-design of a Virtual Training Tool with Emergency Management Stakeholders for Extreme Weather Response
2018
Emergency services usually prepare for the most frequent or predictable types of disasters, such as fires. However, preparation for complex, unpredictable disaster scenarios is infrequent, probably because of high resource demand and difficulty of covering dynamic training needs of multiple stakeholders. The use of serious game techniques as the core of simulated or virtual training tools opens for new ways of training and learning in emergency and crisis scenarios. However, the number of virtual training tools customized to specific disaster or crisis scenario that address needs of diverse user groups is limited. Existing tools are often tailored with a particular geographical setting and …
