Locality-Adaptive Parallel Hash Joins Using Hardware Transactional Memory

Previous work [1] has claimed that the best performing implementation of in-memory hash joins is based on (radix-)partitioning of the build-side input. Indeed, despite the overhead of partitioning, the benefits from increased cache-locality and synchronization free parallelism in the build-phase outweigh the costs when the input data is randomly ordered. However, many datasets already exhibit significant spatial locality (i.e., non-randomness) due to the way data items enter the database: through periodic ETL or trickle loaded in the form of transactions. In such cases, the first benefit of partitioning — increased locality — is largely irrelevant. In this paper, we demonstrate how hardware transactional memory (HTM) can render the other benefit, freedom from synchronization, irrelevant as well. Specifically, using careful analysis and engineering, we develop an adaptive hash join implementation that outperforms parallel radix-partitioned hash joins as well as sort-merge joins on data with high spatial locality. In addition, we show how, through lightweight (less than 1% overhead) runtime monitoring of the transaction abort rate, our implementation can detect inputs with low spatial locality and dynamically fall back to radix-partitioning of the build-side input. The result is a hash join implementation that is more than 3 times faster than the state-of-the-art on high-locality data and never more than 1% slower
Modeling many-body physics with Slave-Spin Mean-Field: Mott and Hund's
  physics in Fe-superconductors

Slave-spin mean-field theory, a light and accurate technique to model
electronic correlations in Fermi-liquid phases of multi-orbital materials, is
pedagogically exposed in this chapter, with a focus on its recent successful
application to the physics of Iron-based superconductors. Beside introducing
electronic correlations and recalling the Fermi-liquid phenomenology, the
manuscript accompanies the step-by-step explanation of the slave-spin technique
with a set of useful complements providing analytical insight into Mott and
Hund's physics, which are at the heart of the physics of strongly correlated
materials. Some original research material is also exposed, such as the
Hund-induced shrinking of the Hubbard bands flanking the gap of the half-filled
Mott insulator, and the low-energy description of the "orbital-decoupling"
mechanism.Comment: 58 pages, 19 figures. Original research material on Hund's physics
  (see abstract) is presented in the manuscript, supplementing the main subject
  about the lectures prepared for the "XIX Training Course in the Physics of
  Strongly Correlated Systems", Vietri sul Mare, Italy - October 201
A data- and model-driven analysis reveals the multi-omic landscape of ageing

Altered expression of a number of genes has been correlated to biological ageing\ud
in humans. The biological age predicted from gene expression levels is known\ud
as transcriptomic age. This di ers from chronological age which is measured\ud
as the time that an individual has lived since their date of birth. Transcrip-\ud
tomic age can be older or younger than an individual's chronological age. At\ud
present, studies have focused on using transcriptomic data to predict transcrip-\ud
tomic age. However, this approach largely does not consider the e ect that genes\ud
have on the metabolic network and therefore on the observable cellular pheno-\ud
type. This research takes the current understanding of transcriptomic ageing a\ud
step further by generating and investigating genome-scale metabolic models of\ud
ageing, using machine learning methods and a multi-omic approach based on\ud
constraint-based modelling. We combine these models with a transcriptomic age\ud
predictor and gene expression data from CD4 T-Cells from human peripheral\ud
blood mononuclear cells in healthy individuals. We show that metabolic models\ud
augmented with transcriptomics data of ageing can generate greater metabolic\ud
insights into the di erences between chronological and transcriptomic age. Com-\ud
pared to standard transcriptomic-only approaches, our method provides a more\ud
comprehensive analysis of transcriptomic ageing and paves the way for a multi-\ud
omic understanding of ageing mechanisms in human cells
A Quantitative Analysis of the Memory Architecture of FPGA-SoCs

In recent years, so called FPGA-SoCs have been introduced by Intel (formerly Altera) and Xilinx. These devices combine multi-core processors with programmable logic. This paper analyzes the various memory and communication interconnects found in actual devices, particularly the Zynq-7020 and Zynq-7045 from Xilinx and the Cyclone V SE SoC from Intel. Issues such as different access patterns, cache coherence and full-duplex communication are analyzed, for both generic accesses as well as for a real workload from the field of video coding. Furthermore, the paper shows that by carefully choosing the memory interconnect networks as well as the software interface, high-speed memory access can be achieved for various scenarios
Layout analysis and content classification in digitized books

Automatic layout analysis has proven to be extremely important in the process of digitization of large amounts of documents. In this paper we present a mixed approach to layout analysis, introducing a SVM-aided layout segmentation process and a classification process based on local and geometrical features. The final output of the automatic analysis algorithm is a complete and structured annotation in JSON format, containing the digitalized text as well as all the references to the illustrations of the input page, and which can be used by visualization interfaces as well as annotation interfaces. We evaluate our algorithm on a large dataset built upon the first volume of the “Enciclopedia Treccani”
Dealing with Culture in Schools: A Small-Step Approach Towards Anti-racism in Finland

This chapter discusses anti-racism education by focusing on how culture is used in educational discourses in Finland. More and more studies highlight the pervasive use of culture as a substitute for race, urging scholars to explore how and why cultural claims are made relevant (Breidenbach & Nyíri, 2009; Piller, 2011). Culture is present in numerous subjects (e.g. religion, literature, history, languages) and anti-racism education should therefore be understood from a holistic perspective. This chapter focuses on the Finnish context which is relevant to examine for two main reasons. First, Finnish school system is globally represented as high-quality. Second, the new national curriculum, which reflects current ideas and values, will be applied in August 2016.\ud
Drawing on critical approaches to culture, this chapter (1) looks at limitations of the way culture is conceptualized within educational discourses, (2) proposes new ways of using the concept (3) and provides practical examples while considering limitations and challenges such as hidden curriculum and teachers’ personal values. This chapter will primarily deal with foreign language education since one of its main objectives, as stated by the new curriculum, is to “increase cultural diversity and language awareness”1 (Opetushallitus, 2014, p. 219 & p. 349).\ud
Building on intercultural communication and educational research, and using the experience of one of the authors as a teacher, this study bridges the gap between theoretical insights and practical implications. With the aim of providing applicable findings, we argue for a variety of small changes in existing practices rather than the addition of a large anti-racism programme
Restoring Mesh Independency in FEM-DEM Multi-scale Modelling of Strain Localization Using Second Gradient Regularization

Continuum media from classical mechanics cannot appropriately reproduce the evolution of materials exhibiting strong heterogeneities in the strain field, e.g. strain localization. Models without a microscale representation cannot properly reproduce the microscale mechanisms that trigger the strain localization, in addition, first gradient relations don’t present any length parameter in the formulation. This results in a model without a characteristic length that cannot exhibit any objective band width. In this paper, techniques to introduce an internal length will be enumerated. Microstuctured materials will be retained and in particular Second Gradient model will be exposed and used along with a FEMxDEM approach. Numerical results showing the abilities of the enriched model will conclude the text
An Evaluation Framework and Database for MoCap-Based Gait Recognition
  Methods

As a contribution to reproducible research, this paper presents a framework
and a database to improve the development, evaluation and comparison of methods
for gait recognition from motion capture (MoCap) data. The evaluation framework
provides implementation details and source codes of state-of-the-art
human-interpretable geometric features as well as our own approaches where gait
features are learned by a modification of Fisher's Linear Discriminant Analysis
with the Maximum Margin Criterion, and by a combination of Principal Component
Analysis and Linear Discriminant Analysis. It includes a description and source
codes of a mechanism for evaluating four class separability coefficients of
feature space and four rank-based classifier performance metrics. This
framework also contains a tool for learning a custom classifier and for
classifying a custom query on a custom gallery. We provide an experimental
database along with source codes for its extraction from the general CMU MoCap
database.Comment: Preprint. Full paper published at the 1st IAPR Workshop on

A Glycine-Rich Protein Encoded by Sulfur-Deficiency Induced Gene is Involved in the Regulation of Callose Level and Root Elongation.

Glycine-rich proteins (GRPs) with characteristic repetitive glycine stretches are ubiquitous in organisms of all Kingdoms and have distinct functions. It is believed that Gly-rich domains serve mainly for interactions with other proteins. Previously, we identified the tobacco UP30 gene as strongly upregulated by sulfur deficiency. It encodes a protein  highly similar to cdiGRP involved in tobacco defense response by elevating cell wall callose deposits thus blocking systemic movement of viruses. The closest Arabidopsis thaliana homologue of UP30 is GRP-3 (At2g05520). Here we report that GRP-3 is induced in Arabidopsis seedlings in both sulfur and nitrogen deficiency conditions. The transgenic Arabidopsis plants either overexpressing or with silenced GRP-3 expression tend to have longer roots especially in the conditions of sulfur deficiency. The effect could be reduced by the addition of auxin to the media. Moreover, we observed the increased callose deposition in both Arabidopsis lines suggesting its negative effects on shoot-to-root movement of auxins in nutrient deficient conditions
The sulfur pathway and diagnosis of sulfate depletion in grapevine

Sulfur is an essential nutrient to all plant species. Plants assimilate sulfur
in a well-described pathway, which has been taken up by roots. Regulatory mech-
anism has been the subject of many research papers. However, recent studies
highlighted differences between crop plants and the model plant Arabidopsis
thaliana. Our work focuses on the identification of genes involved in the sulfur
metabolism in the Vitis vinifera genome, and their response to sulfur deficiency and
other abiotic stress endured by grapevine in the field, namely water stress. Here, we
describe the identification and brief characterization of the first assimilation
enzymes involved in the sulfur pathway, the enzyme responsible for sulfur activa-
tion, ATP sulfurylase (ATPS), and the two enzymes that reduce sulfate to sulfide,
Adenosine 50-phosphosulate reductase (APR) and Sulfite reductase (SiR). A reduc-
tion was observed in the number of ATPS and APR isoforms identified in
V. vinifera genome when compared to A. thaliana or Glycine max genomes. Two
ATPS isoforms were present in the Vitis genome, of which only ATPS1 transcript
was detected in the tested tissues, and one APR isoform, suggesting an absence of
redundancy in the role of both enzymes. ATPS1, APR and SiR transcript level was
up-regulated in response to 2 days exposure to sulfur deficiency in V. vinifera cell
cultures, which was completely reversed by the addition of GSH to the culture
medium. Apparently, oxidative stress triggered GSH has a pivotal role in the
regulation of ATPS1, APR and SiR transcription level, since their up-regulation
was observed in mRNA from field grapevine berries under water stress, which is
known to induce oxidative stress.info:eu-repo/semantics/publishedVersio
Compguide: Acquisition and editing of computer-interpretable guidelines

The formalization of Clinical Practice Guidelines (CPGs) as Computer-Interpretable Guidelines (CIGs) has the potential to positively influence the behaviour of health practitioners by being available at the point and time of care. Existing tools for acquiring and editing CIGs for automatic interpretation present limitations in their ease of use and the support they offer to a CIG encoder. Besides characterizing these limitations and identifying improvements to include in future tools, this work describes the CompGuide Editor, a Protégé tool for the management of CIGs that guides a user throughout the several steps of CIG encoding, without requiring the user to have programming knowledge, and through the use of interfaces that are simple and intuitive.FCT - Fuel Cell Technologies Program (SFRH/BD/85291/2012)info:eu-repo/semantics/publishedVersio
Who can assess HR performance in IT/IS projects: a review

Acting in markets characterized by a growing demand, organizations need to manage their human resources effectively and nowadays recognize that human resources (HR) are key elements to obtain success. In fact, organizations, by looking for operation optimization, have interest in enhancing the performance of human resources through systematic appraisals, by collecting and using information from individual and team performance. In the context of information technology/information systems (IT/IS) projects, the research that focuses on HR performance appraisal is scarce. To help fill this gap this paper presents a review of sources on performance information, which are applicable to these kind of projects.This work has been supported by COMPETE: POCI-01-0145-FEDER-007043 and FCT -

Baby steps in E-health: Internet of things in a doctor's office

IoT is a very common buzzword in e-Health because the creation of new and better healthcare services are possible through technology-push. There are great expectations in using IoT in healthcare, but most studies describe very futuristic and disruptive solutions for the healthcare real world. In a near future these solutions could be implemented, but now we need some “baby steps” to reach an e-Health with IoT technology. In this paper it is presented a solution to transform a doctor’s office in an IoT office by helping the doctor attend a patien. This solution has impact in the doctor’s work because (s)he has a limited time to attend a patient and a big part of this time is spent writing the results of the appointment in a computer record - the electronic patient record. By other hand the patient improve their experience because the doctor will give them more attention and care.This work has been supported by COMPETE: POCI-01-0145-

Hand Posture Recognition with standard webcam for Natural Interaction

This paper presents an experimental prototype designed for natural human-computer interaction in an environmental intelligence system. Using computer vision resources, it analyzes the images captured by a webcam to recognize a person’s hand movements. There is now a strong trend in interpreting these hand and body movements in general, with computer vision, which is a very attractive field of research. In this study, a mechanism for natural interaction was implemented by analyzing images captured by a webcam based on hand geometry and posture, to show its movements in our model. A camera is installed in such a manner that it can discriminate the movements a person makes using Background Subtraction. Then hands are searched for assisted by segmentation by skin color detection and a series of classifiers. Finally, the geometric characteristics of the hands are extracted to distinguish defined control action positions
Integration between EVM and Risk Management: proposal of an automated framework

"World Conference on Information Systems and Technologies (WorldCIST 2017)The integration between Earned Value Management (EVM) and Project Risk Management immediately raises the question of the relationship between the two methods, even though EVM and project risk management share the same function in project management: promote the project success. At first glance it seems to be no further connection between these two methodologies, but the fundamentals of EVM are fully influenced by both risk management and risk analyses. This paper seeks to clarify the mechanisms of this function, and in which points they meet or affect each other, with reference to PMBoK®. The several techniques and methods are somewhat disperse and not always coherent. With the several assumptions resulting from the interconnection between the two methods, a framework of integration between them is proposed, as well as its practical implementation in Excel, resulting in a set of tools that can be useful in monitoring and controlling a project.This work has been supported by COMPETE: POCI-01-0145-FEDER-007043 and FCT – Fundação para a Ciência e Tecnologia within the Project Scope: UID/CEC/00319/2013.info:eu-repo/semantics/publishedVersio
Including credibility and expertise in group decision-making process: an approach designed for UbiGDSS

Supporting group decision-making when the decision-makers are
spread around the world is a complex process. The mechanisms of automated
negotiation, such as argumentation, can be used in Ubiquitous Group Decision
Support Systems to help decision-makers find a solution based on their preferences.
However, there are some other important issues that affect the decisionmaking
process beyond typical preferences over criteria and alternatives. In this
paper, we propose an algorithm that will allow agents to reason about self-expertise
and other decision makers’ credibility. This way, we intend agents to achieve
better quality and more consensual decisions. Our algorithm includes not only
the decision-maker’s preferences but also his intentions in the process. By using
the proposed model, agents achieved a stronger consensus in all scenarios that
were considered and higher satisfaction levels in the most complex scenarios.This work was supported by COMPETE Programme (operational programme for competitiveness)

Improving project management practices in architecture & design offices

"World Conference on Information Systems and Technologies (WorldCIST 2017)"This paper describes a study on improving project management (PM) practices in architecture  &  design offices, conducted through semi-structured interviews and focus group with professionals from seven different offices. Taking into account the best PM practices described in literature and the most used practices and problems identified in this particular organizational context, a set of key PM practices are proposed. The results show that there are common practices already used by the architecture  &  design offices, such as: project charter, kickoff meeting, budgeting document and progress meetings. The problems found are mainly related to communication, collecting requirements, schedule control and portfolio management. The set of key PM practices proposed is composed by well-known practices: kick-off meeting, budgeting document, project charter, milestone planning, work packages and deadlines document, communication plan, change request, progress meeting, progress report, meeting minutes, client acceptance form and project closure documentation.This work has been supported by COMPETE: POCI-01-0145-FEDER007043 and FCT – Fundação para a Ciência e Tecnologia within the Project Scope: UID/CEC/00319/2013.info:eu-repo/semantics/publishedVersio
Quantifying the effects of learning styles on attention

Monitoring and managing attention in the classroom is nowadays an
important aspect where the level of learner’s attention affects learning
results. When students are using devices connected to the Internet in learning
activities in which they send and received notifications, beeps, and vibrations
and blinking messages, the ability to focus becomes increasingly important.
This is true in many different domains, from the classroom to the workplace.
This paper deals with the issue of attention monitoring, with the aim of
providing a non-intrusive, reliable and easy tool that can be used freely in
schools or organizations, without changing or interfering with the established
working routines. Specifically, we look at desk students in learning activities, in
which the student spends long time interacting with the computer.This work has been supported by COMPETE: POCI-01-0145-
