Optimal 3D printing of complex objects in a 5 - axis printer
Ramos, Bruna; Pinho, Diana; Martins, Daniela A.L.; Vaz, A. Ismael F.; Vicente, Luis NunesThree-dimensional (3D) printing, also known as additive manufacturing (AM), has emerged in the last decades as an innovative technology to build complex structures. It enables increasing design complexity and low-cost customization with a vast range of materials. AM capabilities contributed to a widespread acceptance of 3D printing in different industries such as the aerospace and the automotive. However, impor...

Ribeiro, Iolanda; Viana, Fernanda Leopoldina; Santos, Sandra Cristina Silva Santos; Cadime, Irene Maria Dias; Medrado, Ilka; Ramos, Bruna; Silva, CarlaEste relatório complementa três relatórios intercalares e é dedicado, essencialmente, à apresentação da avaliação final do projeto. No entanto, procede-se a um enquadramento do projeto e à análise do seu contributo para a promoção do sucesso escolar na Comunidade Intermunicipal do Vale do Ave, à descrição dos objetivos e dos desvios e/ou mudanças introduzidas relativamente à planificação inicial. Integra também...
An arc flow formulation to the multitrip production, inventory, distribution, a...
Ramos, Bruna; Alves, Cláudio; Valério de Carvalho, José ManuelThe multitrip production, inventory, distribution, and routing problem with time windows (MPIDRPTW) is an integrated problem that combines a production and distribution problem, a multitrip vehicle routing problem, and an inventory routing problem. In the MPIDRPTW, a set of customers, which have a time-varying demand during a finite planning horizon, is served by a single production facility. The distribution i...
Análise das interconexões entre a NBR ISO 14001: 2015, a lei 12.305/10 – políti...
Ramos, BrunaThe aim of this study was to research and analyze the existing interconnections between NBR ISO 14001: 2015 and requirements of law 12.305/10 and law 4.624/18 in relation to the destination of solid waste produced by industrial sector in the city of Palhoça in Santa Catarina. A bibliographical review of the theories was carried out and a comparative table was developed that identified the main interconnections ...
Path generation, control, and monitoring
Faria, Carlos; Martins, Daniela A.L.; Matos, Marina A.; Pinho, Diana; Ramos, Bruna; Bicho, Estela; Costa, Lino; Espirito Santo, Isabel; Fonseca, JaimeA critical issue in additive manufacturing (AM) is the control of the printer actuators such that the deposition of material (or a few different materials) takes place in an organized way. Typically, the actuators are connected with a low-level controller that can receive computer numerical control (CNC) instruction. A 3D printer controller is, usually, expected to receive a set of CNC instructions in a format ...

Post-traumatic stress disorder and identity transformation after experiences of...
Ramos, Bruna; Teixeira, Filipa; Começanha, Rita; Maia, ÂngelaPsychological abuse (PA) is being associated with the development of post-traumatic stress disorder (PTSD). However, few studies have focused exclusively in this type of abuse. This study aimed to examine the relationship between PA and PTSD symptoms according to gender and understand the impact of severe PA in identity transformation, in a Portuguese university sample. Using a mixed-methods approach, 158 stude...
Column generation based approaches for combined routing and scheduling
Ramos, Bruna; Alves, Cláudio; Valério de Carvalho, José ManuelThe multi-trip location routing problem is usually applied in the logistics and transportation field. The multi-trip location routing problem is an integrated problem that combines two important and difficult optimization problems: the facility location problem and the multi-trip vehicle routing problem. In the facility location problem, one has to determine the set of facilities that can be used to serve the c...
Skewed general variable neighborhood search for the location routing scheduling...
Macedo, Rita; Alves, Cláudio; Hanafi, Said; Jarboui, Bassem; Mladenovic, Nenad; Ramos, Bruna; Carvalho, J. M. Valério deThe integrated location routing scheduling problem is a variant of the well-known location routing problem. The location routing problem consists in selecting a set of depots to open and in building a set of routes from these depots, to serve a set of customers at minimum cost. In this variant, a vehicle can perform more than a single route in the planning period. As a consequence, the routes have to be schedul...
Decision support subsystem for operations planning in the automotive industry
Ramos, Bruna; Alves, Cláudio; Brás, Pedro Alexandre FonsecaIn this paper, we describe a decision support subsystem that ensures the coordination between different integer programming models through an appropriate algorithm. The algorithm selects the most appropriate model, according to the information to be used during the time period under analysis. The solution given by the algorithm is translated into a set of cutting plans for different raw materials. The Master Pr...
