SAUCE: A Web-Based Automated Assessment Tool for Teaching Parallel Programming

2015

Many curricula for undergraduate studies in computer science provide a lecture on the fundamentals of parallel programming like multi-threaded computation on shared memory architectures using POSIX threads or OpenMP. The complex structure of parallel programs can be challenging, especially for inexperienced students. Thus, there is a latent need for software supporting the learning process. Subsequent lectures may cover more advanced parallelization techniques such as the Message Passing Interface (MPI) and the Compute Unified Device Architecture (CUDA) languages. Unfortunately, the majority of students cannot easily access MPI clusters or modern hardware accelerators in order to effectivel…

Bayesian versus data driven model selection for microarray data

2014

Clustering is one of the most well known activities in scientific investigation and the object of research in many disciplines, ranging from Statistics to Computer Science. In this beautiful area, one of the most difficult challenges is a particular instance of the model selection problem, i.e., the identification of the correct number of clusters in a dataset. In what follows, for ease of reference, we refer to that instance still as model selection. It is an important part of any statistical analysis. The techniques used for solving it are mainly either Bayesian or data-driven, and are both based on internal knowledge. That is, they use information obtained by processing the input data. A…

Digital communication environments in the workplace

2019

Digital communication environments consist of various kinds of communication technologies and collaboration platforms. These enable employees to communicate through text, audio, video, and graphics, often in an open and networked way. Complementing the popular stand-alone communication tools regularly used in workplaces, such as email and instant messaging, digital communication environments enable the sharing, editing, and storing of information publicly within the organization and sometimes externally among its stakeholders. This chapter reviews and analyzes digital communication environments as well as their affordances and constraints for communication and social interaction in the work…

ChiLab4It system in the QA4FAQ competition

2017

ChiLab4It is the Question Answering system (QA) for Frequently Asked Questions (FAQ) developed by the Computer-Human Interaction Laboratory (ChiLab) at the University of Palermo for participating to the QA4FAQ task at EVALITA 2016 competition. The system is the versioning of the QuASIt framework developed by the same authors, which has been customized to address the particular task. This technical report describes the strategies that have been imported from QuASIt for implementing ChiLab4It, the actual system implementation, and the comparative evaluations with the results of the other participant tools, as provided by the organizers of the task. ChiLab4It was the only system whose score re…

REFLECTIONS ON MANAGERIAL COMMUNICATION

2012

Modern management has given an extremely important place to managerial communication. It considers communication as a vital component of the managerial system of all organizations. A successful manager is the one that can communicate with the persons that he or she is leading, and the performance of an organization can be conditioned by the manner in which managers communicate. The identification of employees with the organizational goals, their channeling of efforts for the common objectives, the ability of the manager to assess the results of his or her decisions can be accomplished only by using the resources of managerial communication. A laconic, delayed or confused managerial communic…

SMS Messages in a Daily Finnish Newspaper : The Contect of Proverb Performances

2017

The article focuses on Finnish proverbs as a part of contemporary colloquial written language in everyday use and context. The article offers a view on what is happening with proverbs in the vernacular in Finnish everyday life. Most traditional Finnish proverbs originate from an agrarian context and still use agrarian language, even if nowadays they live in a new context with a new meaning. As empirical material this article uses a special case that demonstrates the use of proverbs in one Finnish newspaper: proverbs in SMS messages published as a letter to the editor in a newspaper. *** Avtorica se osredinja na finske pregovore kot del sodobnega pogovornega pisnega jezika v vsakdanji rabi i…

EDUCAZIONE FAMILIARE E ORIENTAMENTI DI VALORE

2014

L'educazione familiare ha un nesso costitutivo con l'educazione morale. Questa tesi pedagogica diviene particolarmente evidente nella società liquida, soprattutto in ragione del fatto che, in modo solo in apparenza paradossale, molte esperienze appaiono in essa di tipo inaugurale: terreno propizio per le scelte morali. In generale, è nella famiglia come comunità spirituale che è dato trovare la genealogia della persona; in essa si forma la sensibilità del soggetto, il suo stile emotivo singolare come disposizione verso un cespite di senso, assiologicamente ed eticamente positivo - una risposta al suo fondamentale bisogno di riconoscimento.

Geographical Routing for Delay Tolerant Encounter Networks

2007

Delay Tolerant Networks (DTNs) are intermittently connected networks, where direct end--to--end path between communicating nodes may never exist. To achieve eventual delivery some nodes must store messages and wait opportunity to forward them. In mobile environment, one of the most challenging problems for routing protocols is to decide, which nodes should store the message to achieve eventual delivery as quick as possible. Common approach is to propagate message into large group of nodes, hoping one of them will reach the destination. These solutions, however, are not very scalable as they generate plenty of extra load and traffic to network. Further more, message carriers have no means to…

ADM : A Density And Priority Levels Aware Protocol For Broadcasting In Vehicular Ad-Hoc Networks

2014

The broadcasting communication mode is widely used in Vehicular Ad~hoc Networks (VANETs). It is used for sending emergency messages, road-traffic information or to help routing protocols to determine routes. This communication mode is known to be hard to achieve efficiently since it depends on the network density. Indeed, broadcasting methods may cause network congestion if they are not well designed. This paper introduces a novel Autonomic Dissemination Method (ADM) which delivers messages in accordance with given message classes and network density levels. The proposed approach is based on two steps: an offline optimization process and an online adaptation to the network characteristics. …
