Abstract The trend of cost-effective access to space and satellite technologies’ evolution is increasing the small market. However, payloads usually ride as piggyback, being a secondary passenger vector, with very low flexibility in target orbit launch schedule. micro-launchers are designed answer needs missions, payload capacity up 350 kg Low Earth Orbit, aiming turn-over time competitive pric...

Trade-offs between life-history variables can be manifested at either the phenotypic or genetic level, with vastly different evolutionary consequences. Here, we examined whether male decorated crickets (Gryllodes sigillatus) from eight inbred lines and the outbred founder population from which they were derived, trade-off immune effort [lytic activity, phenoloxidase (PO) activity or encapsulati...

Security trade-offs have been established for one-way bit commitment in Ref. [1]. We study this trade-off in two selection settings. We show that for an ‘abelian’ selection rule (exemplified by particle conservation) the standard trade-off between sealing and binding properties still holds. For the nonabelian case (exemplified by angular momentum conservation) the security trade-off can be more...

This paper discusses a trade-off strategy for small projects and presents a preliminary guidelines for assessing the appropriateness of a trade-off. The motivation of this work is to make the development team aware of the performed trade-offs and to see both the associated opportunities and risks, to assess the appropriateness of a trade-off and to gather information for the future development ...

Life-history evolution is determined by the interplay between natural selection and adaptive constraints. The classical approach to studying constrained life-history evolution – Richard Levins’s geometric comparison of fitness sets and adaptive functions – is applicable when selection pressures are frequency-independent. Here we extend this widely used tool to frequency-dependent selection. Suc...

In this paper we introduce a generic approach to analyze system design models with regard to the satisfaction of their Non-Functional Requirements (NFRs) to enable the evaluation of their NFRs’ trade-offs. NFRs and their satisfaction become especially critical and deserve more attention in certain application domains such as real-time and embedded systems. This is mainly due to the constraints ...

It has long been recognized that male mating competition is responsible for the evolution of weaponry for mate acquisition. However, when females mate with more than one male, competition between males can continue after mating in the form of sperm competition. Theory predicts that males should increase their investment in sperm production as sperm competition is increased, but it assumes that ...
