- Computation of the volume of triangulated polyhedraPublication . Gaspar, Miguel
- Computer construction of platonic solidsPublication . Gaspar, M.; Leita, M.; Martins-Ferreira, N.; Panda, B. N.In this paper we develop a novel method to generate a 3D geometrical model from 2D planer images. As an example of application, we construct 3D models of each one of the five platonic solids from their platonic graphs.
- Computer tool for maximizing the placement of congruent polyhedraPublication . Gaspar, M.; Alves, N.; Mateus, A.; Martins-Ferreira, N.Given multiple identical polyhedral objects and a parallelepiped container, how should one place the objects so that the largest number fits inside the container? This simple question is important in many applications, yet the answer is elusive. In fact, we know of no published solution for this very general formulation. Still, in many circumstances, further restrictions apply, resulting in a large number of variations requiring different algorithmic strategies. This paper is the continuation of [12] and focus on the fundamental concepts and tools that are used for this kind of problem, such as the no-fit polygon. We also present some of its many variations, giving in particular one that applies to the stereolithographic rapid prototyping technology.
- Curvas geodésicas : um exemplo com resolução analíticaPublication . Fatelo, J. P.; Martins-Ferreira, N.Apresentamos um exemplo de uma superfície não trivial em R3 na qual as curvas geodésicas são encontradas analiticamente.

- Electric Gap Control in a SemiconductorPublication . Santos, Margarida Cabrita; Silva, E. Lora daWe show that the Bi-Layer Graphene allows the control of its electronic gap under an applied voltage.
- Fabrication of biocompatible hydrogels from pine resinPublication . Mahendra, VidhuraThis short review aims to look at some of the applications based on potential pine associated resin (rosin) composites for cell culture studies via hydrogel fabrication. Although hitherto there are only a few links to pine resin based hydrogel formation in the public domain, literature work based rosin incorporated drug delivery studies and its associated uses can be useful for extensive works on the cell interaction and viability. Rosin in such case may be optimised to afford similar characteristics hence applications.
