About

Alexandre Valle de Carvalho has been a University Professor since 2001, and Assistant Professor in the Department of Computer Engineering (DEI) at the Faculty of Engineering of the University of Porto (FEUP) since 2009. He is a researcher at the Center for Information Systems and Computer Graphics (CSIG) at INESCTEC, since 2001 and senior researcher since 2009. The scientific area of Computer Graphics has been present throughout its academic path, starting with Raytracing and Radiosity Hybrid for the Calculation of Photorealistic Images, of 1994, in the Graphical Interface of the Input Module of Data from the VALORAGUA Model, from 1997, in the Image Synthesis for Virtual Environments Experiences with the RENDERCACHE technique, from 2001., culminating with his PhD entitled “Spatio-temporal Information Management and Visualization” in 2009. Furthermore, other professional activity in Geographic Information Systems, as a scholarship, technical staff and then as a researcher at INESC Porto, motivated the scientific study in this area and in the application domain of urban information management, eDemocracy and eGovernment. The joining of both areas - computer graphics and information systems - as well as the background in urban data management resulted in the theme and PhD work, in management and visualization of space-time information, completed in 2009, where he defended two hypothesis: one in information systems and another in information visualization. Alexandre performs research in these two areas until the present time. Furthermore, he has participated in a considerable number of research and development projects, framed by European projects, R&D national projects and specialized consultancy, having publications indexed in scientific conferences and journals. Regarding economic and direct knowledge extension to society, Alexandre founded SIAGHOS in 2012, towards systems and technology to support observational clinical studies. In this context, it conceived, produced and innovated in information systems to support the registration and analysis processes of observational clinical studies for hematology-oncology diseases. These systems were used by a considerable number of Portuguese hematologists, between 2012 and 2018. Furthermore, in 2015 Alexandre co-founded MITMYNID, an INESC TEC spinoff towards innovative solutions for the Transport and Logistics Sector. At MITMYNID, Alexandre participated in the coordination BIZCARGO and of projects with a high degree of innovation and in the elaboration and execution of proposals and provision of services where innovation is also evident. Examples of this are two P2020 demonstration projects and collaboration on two European projects. In the context of university management, Alexandre performed scientific and pedagogical coordination of curricular units, course groups and degree and master courses.

Abstract
The development of a single window system for collaborative Multimodal Logistics services with offer for optimized and integrated door-to-door services is a complex endeavor. The concept was previously worked on by a set of European projects whose results were taken as best practices and lessons learned from the logistics sector. In this current paper we present a background and the major problems faced by the logistics sector and how IT can address them, and the existing expectations for collaborative real time door-to-door logistics Services. Next, we present the main results, consisting of an innovative system addressing these expectations - the Logistics Single Window. Finally we draw the conclusions from the results and present how the results innovate when compared with current state of the art. © 2017 IEEE.

Spatial-Temporal Data Watch to Digital Media PhD Thesis Proposal in Informatics Engineering

Authors
Dias, L; Carvalho, A; Coelho, A;

Publication
2016 11TH IBERIAN CONFERENCE ON INFORMATION SYSTEMS AND TECHNOLOGIES (CISTI)

Abstract
This paper presents a PhD thesis proposal in Informatics Engineering, scheduled for completion in July 2018. This PhD thesis is part of Spatio-Temporal Information Systems, with applicability in technological communication tools and visual representation of knowledge, for Digital Media (newspapers, radio and television). It is intended to maximize the efficiency and effectiveness of the value of heterogeneous, multivariate, multidimensional information characteristic of this context, produced and shared by different sources, in different formats. It is hoped that participation in this Doctoral Symposium will enrich and update the work in progress and help the preparation of the PhD thesis proposal.

Monitoring Systems for Parallel Distributed Data Management Systems

2016 11TH IBERIAN CONFERENCE ON INFORMATION SYSTEMS AND TECHNOLOGIES (CISTI)

Abstract
Usually, a Big Data system has a monitoring system for performance evaluation and error prevention. Although, there are some disadvantages in the way that these tools display the information and its targeted approach to physical components. The main goal is to study visual and interaction mechanisms that allow the representation of monitoring data in grid computing environments, providing the end-user information which can contribute objectively to the system analysis. This paper has the purpose to present the state of the art, carries out an intermediate evaluation of the current work and present the proposed solution.
