Abstract
The PhDOOS workshop differs from other workshops because the range of participants is much smaller (only PhD students) but has a wide scope of topics. Even with the limitation to PhD students in Object Oriented Systems, the presentations covered topics such as Generic Ownership, Generic Algorithms, Model Driven Architecture, Prediction of Size, QoS assessment, Frameworks, Teaching of Frameworks and Object Calculus. Several topics of shared interest were identified and targeted in separate discussion groups on a general theme on the future of object oriented programming. As the participants had various research interests covering very different parts of the OO spectrum, we can confidently state that these topics reflect actual concerns and needs of the OO community, and emerge from its concrete needs. This document is to be complemented by a workshop proceedings online document which will contain the full versions of the presented papers.

Abstract
A fibre Bragg grating sensing configuration is presented for simultaneous measurement of strain and temperature. The proposed concept relies on writing a single Bragg grating on the splice region of two fibres with different levels of germanium doping. Doing so, a grating structure appears with three resonance peaks, which show distinct temperature sensitivities but similar strain responses. The experimental validation of the concept indicated resolutions of +/-1.5 degreesC Hz(-1/2) and +/-5.6 muepsilon Hz(-1/2) over measurement ranges of 80 degreesC and 1000 muepsilon for temperature and strain, respectively.

Abstract
A dynamic dispersion compensation device using a chirped fibre Bragg grating with a ring geometry embedded in a composite laminated is proposed. A numerical model is presented and compared with the experimental setup. It is shown that the theoretical and experimental results are in good agreement. The tunability of the device is obtained by applying different radius of curvature to the ring structure, and thus producing non-linear variations in the spatial period of the chirped fibre Bragg grating, without changing the usable bandwidth.

Abstract
An evaluation of the influence of environmental factors on the normal growth of young Anodonta cygnea was undertaken in semi-controlled conditions in the natural habitat. Organic and inorganic compounds and the microalgal population composition were analysed for I year in the lagoon habitat and correlated with bivalve length and weight variations. The results from the water samples showed a significant increase in calcium and magnesium in the spring-summer period, suggesting an influence on shell growth that is apparent at this time. Sodium potassium and chloride show no significant variations. The significantly higher lipid concentration in spring, albeit still at a low level, may be related to the increase in body weight during this season, whilst the stable protein and carbohydrate contents provide the bases for growth and metabolism, respectively. An appropriate combination of microalgae, including diatoms, chlorophytes and cyanophytes may be an important factor in the increase in length and weight of young bivalves during spring and autumn periods. This influence seems to be reinforced by association with mild temperatures (12-15degreesC). In contrast, a low rate of growth in summer and its virtual absence in winter are due to the presence, in substantial numbers, of only two kinds of microalgae and high or low temperatures. A high level of survival (85%) of young A. cygnea was observed during the 3-year period of culture. The correlation coefficient between length and weight during the early adult growth period was estimated to be 95%.

Abstract
Generating manipulator trajectories considering multiple objectives and obstacle avoidance is a non trivial optimization problem. In this paper a multi-objective genetic algorithm is proposed to address this problem. Multiple criteria are optimized up to five simultaneous objectives. Simulations results are presented for robots with two and three degrees of freedom, considering two and five objectives optimization. A subsequent analysis of the solutions distribution along the converged non-dominated Pareto front is carried out, in terms of the achieved diversity.

Abstract
Selenastrum, Chlorella and the Cyanophyta groups, important components of the phytoplankton in the natural habitat of Anodonta cygnea in Mira Lagoon, were used separately as experimental diet for Anodonta cygnea. To assess the effects of the different diets, several organic and inorganic compounds of the haemolymph and extrapallial fluid were measured. Protein content was significantly reduced with experimental Non Feed, and carbohydrate content with Non Feed, Selenastrum, Chlorella, and Cyanophyta diets compared to the control in the lagoon. Lipid contents in body fluids were similar among the different diet groups, with the exception of the Chlorella diet, which showed a higher value. In all diets, the inorganic elements, magnesium and chloride, presented a non-significant variation profile. The concentration of sodium and potassium was significantly affected in Selenastrum and Chlorella diets, observing in the Non Feed diet a minimum value for potassium. The non-significant variation of osmolality suggests the presence of a specific osmotic regulatory mechanism independent of the diet. A particular regulation mechanism seems to exist for both calcium and manganese ion inducing similar profiles for all experimental diets with higher contents in Selenastrum and Cyanophyta diets, respectively. The higher calcium ion concentration appears associated with lower protein-carbohydrate contents, probably due to weak calcium aggregation and deposition mechanism, except for the control and Mixture diets. In general, the concentrations of organic and inorganic compounds in the body fluids of Mixture-fed A. cygnea, were more similar to those found in the control diet group. This suggests that an equal mixture of the three algae, Selenastrum, Chlorella, and Cyanophyta, is more appropriate diet to provide the necessary nutrients for a normal maintenance of A. cygnea in the wild.
