This paper presents the Malmö Breast Tomosynthesis project. The tomosynthesis equipment is described as well as the patient selection and image acquisition. Special focus is given to one of the studies of the project, which is a comparison of the diagnostic performance between breast tomosynthesis (BT), digital mammography (DM) and ultrasonography (US): Tumor classification according to the BIR...

A constant time and space algorithm for embedding the hypercube architecture into the 3-dimension mesh (3Dmesh) is presented. This enables the cubei operation to be performed on the embedded hypercube machine where the interprocessor communication function cubei is defined on the embedded hypercube's PEs as cubei (bn−1LbiLb0 ) = bn−1LbiLb0 and bi is the binary complement of bi .

Focusing on the working relationship between Marketing Managers and Sales Managers, our study examines two dimensions of interpersonal conflict: dysfunctional conflict and functional conflict. Drawing on relevant theory, we include three communication variables – frequency, bidirectionality, and quality – as antecedents in our structural model. Using these explanatory variables we predict the t...

We propose a quantum transmission based on bi-photons which are doubly-entangled both in polarisation and phase. This scheme finds a natural application in quantum cryptography, where we show that an eventual eavesdropper is bound to introduce a larger error on the quantum communication than for a single entangled bi-photon communication, when he steels the same information.

The ”bi-directional search method” used for unicast routing is briefly reviewed. The extension of this method unicast QoS routing is discussed and an exact hybrid QoS algorithm HAMCRA that is partly based on bi-directional search is proposed. HAMCRA uses the speed of a heuristic when the constraints are loose and efficiently maintains exactness where heuristics fail. The performance of HAMCRA i...

Small businesses have limited resources that need to be utilised for maximum return. Business intelligence (BI) systems can provide decision-makers, who in small businesses are predominantly the owner-managers, with access to data that enables them to make informed decisions on where to apply their limited resources. Given the dearth of literature on the role of BI in small businesses this rese...

A so-called Standard Bi-Quadratic Optimization Problem (StBQP) consists in minimizing a bi-quadratic form over the Cartesian product of two simplices (so this is different from a Bi-Standard QP where a quadratic function is minimized over the same set). An application example arises in portfolio selection. In this paper we present a bi-quartic formulation of StBQP, in order to get rid of the si...

This paper presents a new e cient method for nding an \optimal" bi-decomposition form of a logic function. A bi-decomposition form of a logic function is the form: f(X) = (g1(X ); g2(X )). We call a bi-decomposition form optimal when the total number of variables in X and X is the smallest among all bi-decomposition forms of f . This meaning of optimal is adequate especially for the synthesis o...

Historically, many data warehousing and business intelligence (BI) initiatives have been IT-driven, and much of the focus within the industry has been on the technical aspects of delivering information to the BI user community. Having arrived at a point where many of the technical challenges and tradeoffs are at least well understood, attention has shifted toward expanding the ways in which BI ...

The logic of bunched implications (BI) of O’Hearn and Pym [5] is a substructural logic which freely combines additive connectives ⊃ , ∧, ∨ from propositional logic and multiplicative connectives −?, ? from linear logic. Because of its concise yet rich representation of states of resources, BI is regarded as a logic suitable for reasoning about resources. For example, by building a model for BI ...
