Mobility, in its various forms, is one of the sources of several technical challenges being addressed in the last years to achieve a more flexible computing and communication infrastructure. In this context, the study and characterization of node mobility in wireless networks is extremely important to foresee the node distribution in the network, thus(More)
The study and characterization of node mobility in wireless networks is extremely important to foresee the node distribution in the network, enabling the creation of suitable models, and thus a more accurate prediction of performance and dependability levels. In this paper we adopt a structured Markovian formalism, namely SAN (Stochastic Automata Networks),(More)
Over the last decades there has been an increased interest in assessing social anxiety in adolescents. This study aims to validate the Social Anxiety Scale for Adolescents (SAS-A) to Portuguese youth, and to examine its invariance across gender as well as its psychometric properties.

Within a total forensic sample of 261 detainee participants, subdivided in a male group (n=217) and a female group(More)
Routing in Delay Tolerant Networks (DTNs) is an aspect of current research. In this kind of network disconnections are frequent and nodes have limited resources, making the design of new routing strategies a challenging task. In previous work we have proposed APRP (Adaptive Potential Routing Protocol) and compared with existing protocols. APRP uses the(More)
The main aim of the present study was to examine the psychometric properties of the Socially Desirable Response Set-5 (SDRS-5) among a forensic sample (N=324) of incarcerated male (n=221) and female (n=103) juvenile offenders. The Portuguese validation of the SDRS-5 demonstrated good psychometric properties, namely in terms of its factor structure, internal(More)
The aim of the present study was to analyze differences regarding psychopathic traits and related constructs in male youths of diverse ethnic backgrounds. The participants were 216 male youths from the Juvenile Detention Centers of the Portuguese Ministry of Justice (White Europeans group: n = 108; ethnic minorities group: n = 108). Psychopathy was measured(More)

A sample of 201 males and 98 females from the Juvenile Detention Centers managed by the Portuguese Ministry of Justice diagnosed with Conduct Disorder (CD) was used. Results showed(More)
The present study assesses swimbladder dynamics in natural occurring sardine, Sardina pilchardus, populations with the aim to examine whether this is affected by bathymetric positioning and the physiological state of the individuals. To do so, swimbladder size and shape were modeled in relation to catch depth and the size of various visceral compartments(More)
