Conditional Random Quantities and Compounds of Conditionals
2013
In this paper we consider finite conditional random quantities and conditional previsions assessments in the setting of coherence. We use a suitable representation for conditional random quantities; in particular the indicator of a conditional event $E|H$ is looked at as a three-valued quantity with values 1, or 0, or $p$, where $p$ is the probability of $E|H$. We introduce a notion of iterated conditional random quantity of the form $(X|H)|K$ defined as a suitable conditional random quantity, which coincides with $X|HK$ when $H \subseteq K$. Based on a recent paper by S. Kaufmann, we introduce a notion of conjunction of two conditional events and then we analyze it in the setting of cohere…
Compound conditionals, Fr\'echet-Hoeffding bounds, and Frank t-norms
2021
Abstract In this paper we consider compound conditionals, Frechet-Hoeffding bounds and the probabilistic interpretation of Frank t-norms. By studying the solvability of suitable linear systems, we show under logical independence the sharpness of the Frechet-Hoeffding bounds for the prevision of conjunctions and disjunctions of n conditional events. In addition, we illustrate some details in the case of three conditional events. We study the set of all coherent prevision assessments on a family containing n conditional events and their conjunction, by verifying that it is convex. We discuss the case where the prevision of conjunctions is assessed by Lukasiewicz t-norms and we give explicit s…
Almost disjoint families of countable sets and separable complementation properties
2012
We study the separable complementation property (SCP) and its natural variations in Banach spaces of continuous functions over compacta $K_{\mathcal A}$ induced by almost disjoint families ${\mathcal A}$ of countable subsets of uncountable sets. For these spaces, we prove among others that $C(K_{\mathcal A})$ has the controlled variant of the separable complementation property if and only if $C(K_{\mathcal A})$ is Lindel\"of in the weak topology if and only if $K_{\mathcal A}$ is monolithic. We give an example of ${\mathcal A}$ for which $C(K_{\mathcal A})$ has the SCP, while $K_{\mathcal A}$ is not monolithic and an example of a space $C(K_{\mathcal A})$ with controlled and continuous SCP …

Floristic affinities between the somali and the mediterranean regions
1988
The phytogeographical connections between Somalia and the Mediterranean Region were analyzed. 99 families and about 300 genera turned out to be common to the two areas, representing 67 per cent of the families and 32 per cent of the genera in the whole Somali flora. If considering only the flora of the northern portion of Somalia, these values respectively reach 76 per cent of the families and 40 per cent of the genera. Furthermore several species are common to the two areas, some showing continuous distribution between eastern Africa and the Mediterranean Region, while others have strongly disjunct distribution.
Ihmeellinen ERP : toiminnanohjausjärjestelmien esittelymateriaalien ja järjestelmien kriittisen tutkimuksen väliset ristiriidat
2016
Tässä tutkimuksessa selvitettiin, kuinka toiminnanohjausjärjestelmien toimittajien esittelemät järjestelmäperustelut poikkeavat järjestelmien kriittisten tutkimusten näkemyksistä. Esittelymateriaalien perusteluita ja kriittisiä tutkimuksia vertailemalla tutkimus pyrki tarjoamaan järjestelmän käyttöönottoa harkitseville yrityksille kriittisen näkökulman järjestelmien esittelymateriaalien tarkasteluun. Tutkimus edustaa laadullista tutkimusta, joka on tyypiltään kartoittavaa ja osin tulkit-sevaa ja kriittistä tutkimusta. Koska tutkimus huomioi erityisesti aineiston kielellisiä piirteitä, diskurssitutkimuksen näkökulmat olivat tutkimuksessa keskeisiä. Tutkimuksen aineisto muodostui kolmen Suome…
Distributed Learning Automata-based S-learning scheme for classification
2019
This paper proposes a novel classifier based on the theory of Learning Automata (LA), reckoned to as PolyLA. The essence of our scheme is to search for a separator in the feature space by imposing an LA-based random walk in a grid system. To each node in the grid, we attach an LA whose actions are the choices of the edges forming a separator. The walk is self-enclosing, and a new random walk is started whenever the walker returns to the starting node forming a closed classification path yielding a many-edged polygon. In our approach, the different LA attached to the different nodes search for a polygon that best encircles and separates each class. Based on the obtained polygons, we perform …
«Den dagen PC-en går i stykker, da er mye av min verden gått i stykker» : En kvalitativ studie om eldres bruk av Duka-PC
2019
Masteroppgave klinisk helsevitenskap ME520 - Universitetet i Agder 2019 Background:Information and communication technology (ICT) affects our everyday lives and the government wants it to be equal opportunities for everyone despite gender, age, background and economy. Many seniors want to be an active player in this digital everyday life. However, lack of knowledge and skills may affectthe confidence to get started. Technological solutions are needed that canmeet their needs and which are adjusted to the functional impairments the individual may have. The importance of facilitated training and user-friendly equipment can be of great value to achieve a greater degree of mastering and confide…
Topology Management in wireless sensor networks
2020
Wireless sensor networking is ingratiating itself into almost every area of human endeavors. Its drivers include its usages, improvements in microelectronics and manufacturing techniques. The network is made up of multiple tiny sensor nodes deployed in the area to be sensed, with nodes having processing, communicating, and sensing capabilities that enable them to perform their function collaboratively. Nodes sense events and transmit their data to the sink directly or through intermediate nodes acting as relay.Despite all the tremendous advances that have been made on this technology over the past few years, energy has not kept pace. This is based mostly on the fact that battery is its main…
