Critical success factors for successful globalised e-learning

2009

As we move from an information-based to a knowledge-based society, the need for reengineering, retraining and restructuring is emerging. Online programme development/enhancement requires experience and planning. Since e-learning entry requires little investments, it can be tempting to start programmes without appropriate infrastructure or planning, resulting in huge losses and in many cases closure. The new entrants can learn from the early adopters of online learning and from their experiences, both good and bad without reinventing the wheel. This paper discusses factors that must be considered and planned before venturing into e-learning. These factors are derived from discussions with fa…

Vārdi starpdisciplinaritāte, starpdisciplinārs pētījums jau labu laiku ir kļuvuši par neatņemamu daļu zinātnieku ikdienas un vēl jo vairāk – projektu valodas – lietojumā. Atslēgvārds, modes vārds – lai kā mēs tos nosauktu, tas gandrīz ir kļuvis par obligātu pētījuma nosacījumu, prasot no zinātnieka drosmi un spēju iziet ārpus savas vienas un vienīgās nozares robežām un analizēt izvēlēto tēmu no vairāku zinātnes disciplīnu skatpunkta. Nesen blakus starpdisciplinaritātes jēdzienam zinātnei veltītajos politiskajos dokumentos un arī citos tekstos aizvien biežāk parādās vēl kāds vārds – transdisciplinaritāte. Atšķirībā no pirmās par šī vārda nozīmi viedokļi dalās, un pagaidām tāda līdz galam vie…

Balancing and clustering of words: a combinatorial analysis of the Burrows & Wheeler Transform

2010

The Burrows-Wheeler Transform (denoted by BWT) is a well founded mathematical transformation on sequences introduced in 1994, widely used in the context of Data Compression and recently studied also from a combinatorial point of view. The transformation does not itself compress the data, but it produces a permutation bwt(w) of an input string w that is easier to compress than the original one, with some fast locally-adaptive algorithms, such as Move-to-Front in combination with Huffman or arithmetic coding. It is well-known that in most real texts, characters with the same or similar contexts tend to be the same. So, the BWT tends to group together characters which occur adjacent to similar…

Fostering the energy efficiency through the energy savings: The case of the University of Palermo

2019

This paper reports the strategy implemented by the Palermo University (Italy) aimed at fostering the energy performance of its campus, particularly towards financing energy saving measures. The basic idea is that the money saved through the energy efficiency actions, constitute the main flywheel to fund further savings and energy efficiency interventions. Results of this paper might bring a useful contribution to the energy planning of cities, since campuses may be regarded as emblematic case study of what can be done in cities because they reproduce, at a little scale, the functioning of wider urban contexts.

A New Class of Searchable and Provably Highly Compressible String Transformations

2019

The Burrows-Wheeler Transform is a string transformation that plays a fundamental role for the design of self-indexing compressed data structures. Over the years, researchers have successfully extended this transformation outside the domains of strings. However, efforts to find non-trivial alternatives of the original, now 25 years old, Burrows-Wheeler string transformation have met limited success. In this paper we bring new lymph to this area by introducing a whole new family of transformations that have all the "myriad virtues" of the BWT: they can be computed and inverted in linear time, they produce provably highly compressible strings, and they support linear time pattern search direc…

Validation of the use of Actigraph GT3X accelerometers to estimate energy expenditure in full time manual wheelchair users with spinal cord injury.

2013

Study design: Cross-sectional validation study. Objectives: The goals of this study were to validate the use of accelerometers by means of multiple linear models (MLMs) to estimate the O2 consumption (VO2) in paraplegic persons and to determine the best placement for accelerometers on the human body. Setting: Non-hospitalized paraplegics’ community. Methods: Twenty participants (age=40.03 years, weight=75.8 kg and height=1.76 m) completed sedentary, propulsion and housework activities for 10 min each. A portable gas analyzer was used to record VO2. Additionally, four accelerometers (placed on the non-dominant chest, non-dominant waist and both wrists) were used to collect second-by-second a…

Painful procedures in the NICU

2012

The authors after a brief introduction on the development of the perception of pain in the fetus and newborn, focus attention on the problem of painful procedures that are performed in the neonatal intensive care units reported in the scientific literature. Then report the design of the double-blind study that is taking place from February 2012 at the NICU ARNAS Civic - Palermo using three different concentrations of sucrose as analgesia during venipuncture and heel puncture in term neonates.

Ligand engineering in Cu(ii) paddle wheel metal–organic frameworks for enhanced semiconductivity

2020

We report the electronic structure of two metal-organic frameworks (MOFs) with copper paddle wheel nodes connected by a N2(C2H4)3 (DABCO) ligand with accessible nitrogen lone pairs. The coordination is predicted, from first-principles density functional theory, to enable electronic pathways that could facilitate charge carrier mobility. Calculated frontier crystal orbitals indicate extended electronic communication in DMOF-1, but not in MOF-649. This feature is confirmed by bandstructure calculations and effective masses of the valence band egde. We explain the origin of the frontier orbitals of both MOFs based on the energy and symmetry alignment of the underlying building blocks. The effe…

Evaluation of GPU-based Seed Generation for Computational Genomics Using Burrows-Wheeler Transform

2012

Unprecedented production of short reads from the new high-throughput sequencers has posed challenges to align short reads to reference genomes with high sensitivity and high speed. Many CPU-based short read aligners have been developed to address this challenge. Among them, one popular approach is the seed-and-extend heuristic. For this heuristic, the first and foremost step is to generate seeds between the input reads and the reference genome, where hash tables are the most frequently used data structure. However, hash tables are memory-consuming, making it not well-suited to memory-stringent many-core architectures, like GPUs, even though they usually have a nearly constant query time com…
