Harassment, based on photos available on social media and other electronic media, has become a major problem in developing countries where internet usage has emerged without adaptation to privacy, awareness etc. We have developed a software sensing layer on top of existing software that would exploit the social connections and use that information to make sure certain images are revealed or not across...
A major cyber-security concern to date for webservers are Distributed Denial of Service (DDoS) attacks. Previously we proposed a novel overlay-based method consisting of distributed network of public servers (PS) for preparation, and access nodes (AN) for actual communication. The AN's performance is evaluated under difficult to detect HTTP(S)-DDoS attacks. Yet, attackers may attempt service denial...
Campus networks and enterprise networks increasingly depend on middleboxes (e.g., firewalls, NAT, load balancers, IDS/IDP) to provide essential services or enforce network policies. These middleboxes often limit the performance of network applications, especially those involved in big data transfer. To address this problem, we propose a Software Defined Networking (SDN) campus network architecture,...
Cyber physical Systems (CPS) are a key technology to enable the development of highly automated and autonomous maritime systems. The development of new complex and distributed safety-critical systems increases the challenges of testing due to a variety of Verification and Validation (V+V) methods, strictly required confidence to functional correctness of heterogenous cooperating systems and management...
Self-monitoring enables patients to become more active participants in their health care, home pulse oximetry can provide objective data for determining health status and the possible need for medical consultation or interventions. Pulse oximetry is a non-invasive and continuous method for monitoring the blood oxygen saturation level. Pulse oximetry has gained acceptance in the medical community caused...
Various current trends such as ever growing population have effectively promoted the growth of Wireless Body Area Network (WBAN). Most of the existing works in WBAN focus on theoretical performance enhancement, whereas works in implementation which is of significance in validation and further research are pretty rare. Therefore, a reliable and efficient system designed both in hardware and software...
The term Conformal Printing refers to 3D printing onto uneven surfaces. Whilst some very high priced solutions exist for known uneven surfaces, where the toolpath is generated in advance, based on CAD data of the object to be printed onto, there is nothing available yet for conformal printing onto unknown uneven surfaces that are scanned on-the-fly. A low-cost prototype named ‘InSPIREd’ was recently...
Heterogeneity of current software solutions for 5G is heading for complex and costly situations, with high fragmentation, which in turn creates uncertainty and the risk of delaying 5G innovations. This context motivated the definition of a novel Operating Platform for 5G (5G-OP), a unifying reference functional framework supporting end-to-end and multi-layer orchestration. 5G-OP aims at integrated...
Due to degradation effects, electric vehicle batteries (EVBs) have a lifetime of approximately ten years in electric vehicles (EVs). Recycling EVBs is inefficient and ecologically undesirable if the batteries can be repurposed to second life scenarios. Decision support systems (DSSs) can be implemented to identify the best second life scenario for which to repurpose individual batteries. However,...
This paper introduces TestMEReq, an automated tool for early validation of requirements. TestMEReq supports requirements engineers (REs) in the validation of the correctness, completeness and consistency of elicited requirements with minimum effort and time through generated abstract tests components: test requirements and test cases, and a mock-up prototype of the user interface (UI). Abstract tests...
User interface prototypes are effective structure for describing as models for web application development thanks to their graphical and dynamic architecture. It provides the benefits such as language independent development, less error-prone and increased quality. The executable programming codes are created by code transformation feature of model-driven development tools as well. Nevertheless, this...
The proposed paper describes the Fire-HEXBOOT prototype's implementation, consisting of the hexapod-propulsion module, the fire detection and its extinguishing system. During the prototype testing some adjustments in terms of sensors, servomotor response times, balancing of the displacement structure have been solved and optimized. Specifically, the developed robot has mechatronic system dedicated...
Self-Organizing Maps (SOM) [ ] are a popular clustering and visualization algorithm. Several implementations of the SOM algorithm exist in different mathematical/statistical softwares, the main one being probably the SOM Toolbox [2]. In this presentation, we will introduce an R package, SOMbrero, which implements several variants of the stochastic SOM algorithm. The package includes several diagnosis...
This paper presents research on identifying and implementation of "game jam " model in an organization dedicated to developing software that has different teams of engineers in various disciplines, such as software engineers, electronic and specialists in art and design Game jam has a promising approach in the rapid development of projects or new products. Our goal is to implement the Game...
This paper describes the development of "Protoboy", an educational and fun alternative that applies aspects of Digital Game-Based Learning (DGBL) and gamification in order to motivate students during their education to gain knowledge about logic and computer programming. The software prototype built allows providing programming concepts and challenges that are fun and intuitive. The tests...
The artificial vision is a part of the artificial intelligence that pretends to simulate the human vision, is to say, from the acquisition, processing, analysis and interpretation of images through an intelligent system. This work presents the creation of prototypes under the game jam model as a software product. In this context, the objective of the present work was to apply basic artificial vision...
Hearing aids are a field of medical devices, powered by digital signal processing techniques. Development of hearing aid modules is realized usually in the first stages using prototyping boards equipped with specialized Embedded DSP. The paper presents a generic model of a hearing aid developed on a DSP development system. The method used to develop and prototype the model (Rapid prototyping) is the...
This paper aims to present an ongoing PhD research project in Information and Communication in Digital Platforms course of University of Aveiro and University of Porto. This study, which started in June/2016 and is 24 months long, aims to study, conceptualize, prototype and validate a system for personalized and dynamic recommendation of informative videos about public and social services, for later...
This paper presents the results of the VR4RE (Virtual Reality for Real Estate) project, which aims at saving time and money for both real estate sellers and buyers by employing modern technologies. VR4RE is one of the innovative projects developed by Bluemind Software and it is in an advanced state. This paper also illustrates the history of in-house technological attempts at creating appropriate...
The accomplishment of any software system success depends on how well it meets the requirements of the stakeholders. These requirements are elicited from the customers. Software requirements are unambiguous if and only if it has one meaning. The elicited requirements are documented in software requirements specification document and these requirements are written in natural languages. Natural languages...
