We have observed a sample of eleven PNe using the PHT-C100 camera on ISO, obtaining maps at 60 and 100 m. The PHT-32 mapping mode was used, resulting in images of the PNe and nearby sky background. A preliminary reduction of the data has conrmed that the radial extent of the cool dust in general is similar to the optical nebula. Two of the PN in our sample have been clearly resolved at 60 and 1...

this study presents a new approach to control the nonlinear dynamics of an adaptive absorber using shape memory alloy (sma) element. shape memory alloys are classified as smart materials that can remember their original shape after deformation. stress and temperature-induced phase transformations are two typical behaviors of shape memory alloys. changing the stiffness associated with phase tran...

In this paper we present new results on detection and removal of redundancies of IF-THEN rules in so-called linguistic descriptions (systems of such rules). We introduce an algorithm for removal of redundancies and describe a practical application.

We prove a generalization of the Hochster-Roberts-Boutot-Kawamata Theorem conjectured in [1]: let R → S be a pure homomorphism of equicharacteristic zero Noetherian local rings. If S is regular, then R is pseudo-rational, and if R is moreover Q-Gorenstein, then it is pseudo-log-terminal.

In this paper we study particular classes of pseudo-BCK algebras, bounded or not bounded, as pseudo-BCK(pP) algebras, pseudo-BCK(pP) lattices, pseudo-Hájek(pP) algebras and pseudo-Wajsberg algebras. We introduce new classes of pseudo-BCK(pP) lattices, we establish hierarchies and we give some examples. We work with left-defined algebras and we work with → and ; as primitive operations, not with...

The research re ected in this dissertation is a study of computational pseudo randomness More speci cally the main objective of this research is the e cient and simple construction of pseudo random functions and permutations where e ciency refers both to the sequential and parallel time complexity of the computation Pseudo random functions and permutations are fundamental cryptographic primitiv...

A pseudo-arc in PG(3n− 1, q) is a set of (n− 1)-spaces such that any three of them span the whole space. A pseudo-arc of size qn + 1 is a pseudo-oval. If a pseudo-oval O is obtained by applying field reduction to a conic in PG(2, qn), then O is called a pseudo-conic. We first explain the connection of (pseudo-)arcs with Laguerre planes, orthogonal arrays and generalised quadrangles. In particul...

intestinal pseudo-obstruction is a condition in which the intestine’s ability to push food through is reduced. it often leads to the dilation of the various parts of the bowel. it can be idiopathic or inherited from a parent, or caused by another disease. we report a rare case of human immunodeficiency virus (hiv) infection in a 3-year-old boy who referred with acute abdominal pain, and was lat...
