Spatial Effects: Binaural Simulation of Sound Source Motion
This report considers the technology needed to achieve binaural simulation of sound source motion based on a single-channel audio input. To do so will require an understanding of Interaural Time Differences, Interaural Level Differences, spectral cues, falloff with distance and the Doppler Effect. Binaural reproduction will be discussed as well as the outline of a simple simulation setup.Architecture & Allied Art
Politics at the mall: the moral foundations of boycotts
This article examines the motivations of liberals and conservatives to boycott and buycott. Nine studies demonstrate that although both liberals and conservatives engage in consumer political actions, they do so for different reasons influenced by their unique moral concerns: Liberals engage in boycotts and buycotts that are associated with the protection of harm and fairness moral values (individualizing moral values), whereas conservatives engage in boycotts and buycotts that are associated with the protection of authority, loyalty, and purity moral values (binding moral values). In addition, the individualizing moral values lead to a generally more positive attitude toward boycotts, which explains why liberals are more likely to boycott and buycott. Liberals' greater concern for the suffering of others and unfair treatment makes them more likely to engage in consumer political actions. Conservatives, in turn, engage in consumer political actions in relatively rarer cases in which their binding moral values are affected by corporate activity.info:eu-repo/semantics/publishedVersio
Spatial Effects: Binaural Simulation of the Doppler Effect
The aim of this project was to source exiting MATLAB code which were able to take a single channel sound and reproduce it binaurally (over headphones) in a way that simulates the motion of a sound source in a straight line as it passes in front of an observer.Architecture & Allied Art

Dynamic Security-aware Routing for Zone-based data Protection in Multi-Processor System-on-Chips
In this work, we propose a NoC which enforces the
encapsulation of sensitive traffic inside the asymmetrical security
zones while using minimal and non-minimal paths. The NoC
routes guarantee that the sensitive traffic is communicated only
through the trusted nodes which belong to the security zone.
As the shape of the zones may change during operation, the
sensitive traffic must be routed through low-risk paths. We test
our proposal and we show that our solution can be an efficient
and scalable alternative for enforce the data protection inside the
MPSoC
Grafting luminescent metal-organic species into mesoporous MCM-41 silica from europium(III)tetramethylheptanedionate, Eu(thd)3
Mixed systems with Eu(III) β-diketonates as optically active guest species, and mesoporous silicas MCM-41 as a host matrix have been investigated. The grafting of europium(III) onto the inner walls of unmodified MCM-41 has been achieved starting from Eu(thd)3 (thd = 2,2,6,6- tetramethyl-3,5-heptanedionate), using two routes: wet impregnation (WI) at room temperature,and chemical vapour infiltration (CVI) at 185 °C. In received hybrids, denoted Eu(thd)x@MCM- 41, the same maximum yield [Eu]/[Si] = 8.2 at% on average has been achieved with either methods. The molar ratio x = [thd]/[Eu] is 0.6 on average for WI samples, and 1.5 for CVI samples. In the latter, higher contents in thd compensate lower contents in silanols with respect to
the former. Rationalizing the possible bonds exchanged at the silica surface leads to a great diversity of possible co-ordination schemes according to the expression Σ[Si(OH)nx
(O)xEu(thd)3-x] (where Σ means that surface species are considered). Chromophore neutral ligands phenanthroline (phen) or bipyridine (bipy) have been added to induce efficient Eu3+ luminescence under 270–280 nm excitation, via the antenna effect. For the most favourable case, (phen)yEu(thd)x@MCM-41, the emission intensity at 612 nm under excitation at 270 nm is 2/3 that for the genuine heteroleptic complex Eu(thd)3(phen). Moreover the hybrid material is stable up to 440 °C
Affiliative Subgroups in Preschool Classrooms: Integrating Constructs and Methods from Social Ethology and Sociometric Traditions
Recent studies of school-age children and adolescents have used social network analyses to characterize selection and socialization aspects of peer groups. Fewer network studies have been reported for preschool classrooms and many of those have focused on structural descriptions of peer networks, and/or, on selection processes rather than on social functions of subgroup membership. In this study we started by identifying and describing different types of affiliative subgroups (HMP- high mutual proximity, LMP- low mutual proximity, and ungrouped children) in a sample of 240 Portuguese preschool children using nearest neighbor observations. Next, we used additional behavioral observations and sociometric data to show that HMP and LMP subgroups are functionally distinct: HMP subgroups appear to reflect friendship relations, whereas LMP subgroups appear to reflect common social goals, but without strong, within-subgroup dyadic ties. Finally, we examined the longitudinal implications of subgroup membership and show that children classified as HMP in consecutive years had more reciprocated friendships than did children whose subgroup classification changed from LMP or ungrouped to HMP. These results extend previous findings reported for North American peer groups
