The paper considers spacecraft motion planning based on the use of safe positively invariant sets. In this approach, a connectivity graph is constructed between a set of forced equilibria, forming a virtual net that is centered around a nominal orbital position. The connectivity between two equilibria is determined based on safe positively invariant sets in order to guarantee that transitions b...

to recall certain normal processes involved in this function. In the laryngo-pharynx the most important mechanism is the closure of the larynx. This is effected by the apposition and tilting forward of the arytenoids and the apposition of the aryepiglottic folds, while a raising of the larynx brings the arytenoids with their cornicula into contact with the cushion of the epiglottis. The contrac...

In this work, the dynamical behavior of a pantographic structure undergoing large deformations is analyzed. A harmonic force applied on structure, while its motion in time recorded by means high-speed camera system. The resulting displacement field obtained via digital image correlation (DIC) method for whole domain. parametric study with respect to amplitude imposed exhibits appearance non-lin...

This article investigates how the identity and sense of belonging evident among young Muslims in Birmingham, England are effected by city’s ‘problematisation’. To do so, this presents findings from new empirical data gathered 125 respondents aged between 18 25 all whom identified as Muslim were resident Birmingham. Having contextualised problematisation, British ‘politics belonging’, adopts a t...

This paper describes how biologically-inspired agents can be used to solve complex routing problems incorporating prioritized information flow. These agents, inspired by the foraging behavior of ants, exhibit the desirable characteristics of simplicity of action and interaction. The collection of agents, or swarm system, deals only with local knowledge and exhibits a form of distributed control...

The dipolar energy contribution to the anisotropy of M, Wand Y-type hexagonal fenites is examined. The geometrical coeff~cients kij are given, so that a calculation for any hexaferrite with the same structure can be effected. Differences in the results of previous works are explained as due to a simplifying assumption, the validity of which is restricted. The ambiguity regarding dipolar energy ...

After the remission of symptoms and reduction in spleen size while on proguanil therapy four patients with the tropical splenomegaly syndrome defaulted from treatment. The withdrawal of proguanil caused a recrudescence of original symptoms, splenomegaly, and a return of the initially raised serum IgM. Complete return to normal values was again effected with proguanil therapy.The role of the spl...

In an endeavor directed towards the construction of the oxabicyclic[3.2.1]octane segment present in the bioactive natural products of cortistatins and icetexanes genre, the title compound, C(13)H(19)BrO(3), was synthesized from (4aR,9aS)-1,3,4,4a,5,6,9,9a-octa-hydro-spiro-[benzo[7]annulene-2,2'-[1,3]dioxolane]-4a-ol via a transannular bromo-etherification protocol. The six-membered ring adopts ...
