In this work, we initiate the study of position-based cryptography in the quantum setting. The aim is to use the geographical position of a party as its only credential. This has interesting applications, e.g., it enables two military bases to communicate over insecure channels and without having any pre-shared key, with the guarantee that only parties within the bases learn the content of the ...

Traceability and authentication of meat and meat products are major concern for consumers, producers and retailers. In Europe, several areas produce high quality dry cured hams under Protected Designation Origin. Efficient and objective methods must be developed to assess origin of dry cured hams. This paper is focused on methods to assess geographical origin, rearing systems and processing con...

In this paper we develop a natural generalization of Schauder basis theory, we term operator-valued basis or simply ov-basis theory, using operator-algebraic methods. We prove several results for ov-basis concerning duality, orthogonality, biorthogonality and minimality. We prove that the operators of a dual ov-basis are continuous. We also dene the concepts of Bessel, Hilbert ov-basis and obta...

Brugada syndrome (BS) is a cardiac disorder characterized by typical ECG alterations, and it is associated with a high risk for sudden cardiac death (SCD), affecting young subjects with structurally normal hearts. The prevalence of this disorder is still uncertain, presenting marked geographical differences. The syndrome has a genetic basis, and several mutations have been identified in genes e...

A model predictive control (MPC) framework, exploiting both feedforward and feedback control loops, is employed to minimize large disturbances that occur in military water networks. Military installations’ need for resilient and efficient water supplies is often challenged by large disturbances like fires, terrorist activity, troop training rotations, and large scale leaks. This work applies th...

This extended abstract summarises our current research which spans the fields of knowledge discovery and software agents. Knowledge discovery (or data-mining) is concerned with extracting knowledge from databases and/or knowledge bases (Piatetsky-Shapiro & Frawley, 1991) using machine learning techniques. Traditionally, data-mining systems are designed to work on a single dataset. However, with...

The cymothoid genus, Pleopodias Richardson, 1910, is revised and a new species from South Africa is recorded. Pleopodias nielbruceisp. n. can be distinguished by large eyes covering majority of the cephalon (almost in contact), antennula bases wide apart, antenna extending to middle of pereonite 2, subtruncate pleotelson, pereopod 7 with numerous acute robust setae on the propodus as well as th...

Let $\mathbb {N}=\{0,1,2,\ldots \}$ and $A\subset \mathbb {N}$. $h\geq 2$ let $r_h(A,n)=\sharp \{ (a_1,\ldots ,a_h) \in A^{h}: a_1+\cdots +a_h=n\}.$ The set $A$ is called an asymptotic basis of order $h$ if $r_h(A,n)\geq 1$ for all sufficiently la

ABSTRACT In “Eden’s Geography Erodes Flood Geology” (The Westminster Theological Journal, Spring, 1996, pp. 123-154), John C. Munday argues that a cataclysmic view of a world-wide flood cannot be supported after an analysis of the geography of Eden. Munday bases his argument on two unproven assumptions: 1) Moses was the author of Genesis two and 2) the account was written from the perspective o...

This paper presents a comparison of tropical deforestation estimates in AVHRR/NOAA and TM/Landsat images for a region in Central Brazil where large clearings in the forest prevail. A TM scene of 02/Sept/89 in the scale of 1:250,000 was visually interpreted to produce a map with four classes: natural forests, deforested areas, natural savannahs, and rivers. The AVHRR image of 17/Sept/89 with ful...
