Within the last years, digital light processing (DLP) became a viable solution for manufacturing of end-use parts in various industries among other additive (AM) processes. As number applications realized rapid (RM) approach grows, it is necessary to understand process economics better when moving from laboratory and prototyping into cost-sensitive production scale. This paper presents producti...

Introduction: Head scans are the most frequently performed computed tomography (CT) examinations worldwide. However, there is growing concern over the probability of increased cancer risks among the exposed populations. Diagnostic reference levels (DRLs) identify radiation dose that is not commensurate with clinical objectives. The aim of this study was to establish DR...

A common clinical problem concerns the utility of repeat lumbar puncture (LP) in adults with acute bacterial meningitis (ABM), e.g., pneumococcal meningitis [1]. An LP is initially done for diagnostic purposes in patients with suspected ABM, i.e., diagnostic lumbar puncture (DLP). A repeat LP (RLP) may be done 1-3 days after the initial DLP, if the patient shows no improvement. If a patient wit...

Finding efficient countermeasures for cryptosystems against fault attacks is challenged by a constant discovery of flaws in designs. Even elements, such as public keys, that do not seem critical must be protected. From the attacks against RSA [5,4], we develop a new attack of DLP-based cryptosystems, built in addition on a lattice analysis [26] to recover DSA public keys from partially known no...

Gaudry has described a new algorithm (Gaudry’s variant) for the discrete logarithm problem (DLP) in hyperelliptic curves. For a hyperelliptic curve of a small genus on a finite field GF(q), Gaudry’s variant solves for the DLP in time O(q2+2). This paper shows that Cab curves can be attacked with a modified form of Gaudry’s variant and presents the timing results of such attack. However, Gaudry’...

The paper presents DLV, a Disjunctive Logic Programming (DLP) system with object-oriented constructs, including classes, objects, (multiple) inheritance, and types. DLV is built on top of DLV (a state-of-the art DLP system), and provides a graphical user interface that allows one to specify, update, browse, query, and reason on knowledge bases. Two strong points of the system are the powerful t...

We investigate the possibility of incorporating Boolean role constructors on simple roles into some of today’s most popular description logics, focussing on cases where those extensions do not increase complexity of reasoning. We show that the expressive DLs SHOIQ and SROIQ, serving as the logical underpinning of OWL and the forthcoming OWL 2, can accommodate arbitrary Boolean expressions. The ...

Computationally binding and perfectly hiding commitments can be constructed from GM-secure public-key encryptions. The main idea is to send an encryption of the message together with the public key. To decommit, we reveal the random bits used to encrypt the message. In fact, one-way functions suffice to construct computationally binding and perfectly hiding commitments. Perfectly binding and co...
