This paper presents an investigation on the compressive behavior of plain concrete columns confined with steel-reinforced grout (SRG) composites. The test parameters include size and crosssectional shape (square or circular) of the columns, and number of layers (one or two) and density (low or medium density) of the steel fiber sheet. Out of 46 specimens herein presented, 33 were confined with SRG

Assistive Technologies offer the possibility to develop services aimed at improving the Quality of Life of patients and caregivers. Specifically, this work refers to the case of persons with dementia who can live in their homes but need to be assisted. This paper describes a monitoring kit that provides alarms to the caregiver in case of dangerous situations or unusual events detected by the senso

The Learning with Errors problem (LWE) has become a central topic in recent cryptographic research. In this paper, we present a new solving algorithm combining important ideas from previous work on improving the Blum-Kalai-Wasserman (BKW) algorithm and ideas from sieving in lattices. The new algorithm is analyzed and demonstrates an improved asymptotic performance. For the Regev parameters $q=n^2$

The Museum Stobaeanum was founded at Lund University, Sweden, in 1735. At the time, Lund was one of Scandinavia’s smallest academies, struggling for survival, and the creation of the museum was part of a modernization process intended to bring the curriculum up to a par with other European universities. The result, however, was one of the last classic Wunderkammern in Europe, reflecting ideals tha

We improve iterative decoding of the moderate density parity-check codes, recently suggested as code candidates in the McEliece public key cryptosystem. In case of bit-flipping (BF) decoder failure, the code parity-check matrix is extended by adding auxiliary variable nodes based on reliability information from the BF decoder. Then iterative decoding is applied to the extended parity-check matrix.

Resilience engineering has changed the value of expertise from meeting required standards, to how it helps organizations to adapt. This chapter discusses the origin of the concept of resilience and how it has been applied to sociotechnical systems within the safety domain. From there we review the current literature to explore how to manage expertise, considering both its possible good and bad eff

The importance of effective facility management in enabling organizations to function efficiently is widely recognized. Total Facility Management offers a comprehensive treatment of what facility management means to owners, operators, tenants, facility managers and professional advisors, as well as containing advice on how facilities can be better managed from a number of perspectives. It consolid

Heterogeneous catalysts for selective oxidation of C-H bonds were synthesized by co-polymerization of new N-heterocyclic carbene-palladium(II) (NHC-PdII) monomers with divinylbenzene. The polymer-supported NHC-PdII-catalysed undirected C-H acetoxylation of simple and methylated arenes as well as polyarenes, with similar or superior efficiency compared to their homogeneous analogues. In particular,

The n = 0 transition multiplet connecting the lowest quartet states of doubly excited C IV has been studied by beam-foil spectroscopy. The fine structure splittings obtained for the 1s2s2p 4p0and 1s2p2 4p terms confirm previous experimental results with an improved accuracy. The average transition wavelength = (1344.49 0.04)A is now more precisely determined by about a factor of eight. At the new

The European Spallation Source (ESS), presently under construction in Lund, Sweden, is designed to be the world's brightest neutron source. When it will be in operation, ESS will deliver an instantaneous neutron flux on detectors that will be without precedent. A down side of the high brightness will be the increase of background, especially from gamma-rays and fast-neutrons.Considering that scatt

An important challenge in the design and implementation of self-optimizing systems is that of finding a model that maps changes in a tunable parameter (or “knob”) into an effect on the performance, power, or energy, of the overall system. This paper describes ARPE (Analyzing the Relationship between Parameters and Effectors), an open source tool to analyze the effect of parameter changes on the be
