La resistenza di interfaccia calcestruzzo poroso-terreni a grana fina per il consolidamento di pendii mediante trincee drenanti profonde

2022

Le trincee drenanti profonde rappresentano uno dei metodi più efficaci per la mitigazione del rischio da frana, in pendii con falda idrica. Esse sono realizzate mediante pannelli o pali secanti. Il riempimento è costituito di calcestruzzo poroso o materiale granulare. Se le trincee sono adeguatamente “innestate” nel terreno stabile e il materiale di riempimento ha sufficiente resistenza e rigidezza come il calcestruzzo poroso, si ha ulteriore in-cremento di resistenza a taglio per effetto shear keys, oltre a quello derivante dalla riduzione delle pressioni in-terstiziali. L’incremento di resistenza è dovuto sia alla resistenza all’interfaccia calcestruzzo–terreni sia a quella intrinseca del…

interface shear strengthPervious concreteSettore ICAR/07 - Geotecnicashear keys effect. Pervious concrete for deep trench drains used to stabilise slopes must simultaneously satisfy many requirements namely adequate hydraulic conductiv-ity adequate shear strength a few days after pour-ing capacity to act as a protective filter for soils in which the drain is installed good resistance to clog-ging and adequate residual hydraulic conductivity. The pervious concrete with appropriated mix-design can effectively satisfy all the abovementioned requirements. If the trenches depth is such that they intersect the sliding surface and if the trenches are adequate-ly "socket" in the layers of stable soil there is a fur-ther increase in shear strength due to the shear keys effect. This latter is in addition to the increase in shear strength resulting from the reduction of inter-stitial pressures that remains the principal scope of the draining trenches. Obviously the increase of shear strength due to the shear keys effect occurs if the trenches are filled with material that have enough strength and stiffness such as the porous concrete. In this case the beneficial effects of the draining trenches on stability are also due to the resistance at the concrete interface of the trench - soils and to the intrinsic resistance of the concrete at the area of the trench intersected by the sliding surface taken into consideration.The increase in resistance due to the shear keys effect can be very significant in relation to the thickness and interspace of the trenches. Results reported in the paper demonstrated that the interface fine grained soil-pervious concrete is higher than the residual shear strength of the soil.

Joukkoistamisen käyttö vaatimusmäärittelyssä : tapaustutkimus

2017

Tämän pro gradu -tutkielman lähtökohta oli tutkia, miten joukkoistamista voidaan käyttää vaatimusmäärittelyssä. Kirjallisuuskatsauksen lisäksi luotiin joukkoistetun vaatimusmäärittelyn malli sekä tehtiin tapaustutkimus KoiraNet jalostustietojärjestelmän MH-luonnekuvausta koskevaan dataan liittyvien käyttötarpeiden selvittämisestä ja joukkoistetusta vaatimusmäärittelystä. Joukkoistaminen tapahtui projektia varten luodussa Facebook-ryhmässä, johon saatiin avoimella kutsulla kaikkiaan 107 jäsentä. Tutkimuksen tuloksiin lukeutui paitsi kerätyt vaatimukset, myös joukon aktiivisuudesta tehdyt määrälliset havainnot. Joukkoistamalla kerättyjen vaatimusten laadun arvioimiseksi suoritettiin erilliset…

Development of an Agile Requirements Risk Prioritization Method : A Design Science Research Study

2023

The practice of information systems development (ISD) has changed during the past two decades from very structured approaches to agile ISD methods. However, many methods available for managing requirements-related risks in the literature follow the structured way of doing ISD. If any, few methods offer solutions to prioritize requirements risks for agile ISD projects based on recognizing requirements-related risks and patterns to mitigate these. To fill this gap in the literature, we apply the design science research methodology to develop an agile requirements risk prioritization method together with industry experts (n=54) in Finland and New Zealand in a multi-year study. The method was d…

Managing and prioritizing requirements risks in information systems development

2018

Tietojärjestelmien suunnittelussa ja toteutuksessa järjestelmän tavoite ja ominaisuudet kuvataan tietojärjestelmän vaatimuksina. Tietojärjestelmävaatimusten keräämisen, kehittämisen ja hallinnan prosessit tietojärjestelmien kehityksessä tähtäävät siihen, että järjestelmän vaatimukset saadaan koottua sidosryhmiltä, ne analysoidaan huolellisesti ja ilmaistaan vaatimukset järjestelmän kehittäjille asianmukaisessa muodossa. Tämä menettely mahdollistaa käyttötarkoitusta vastaava järjestelmän toteuttamisen. Tämän päivän tietojärjestelmäkehityksessä erilaisten ketterien kehitysmallien merkitys on kasvanut, ja voidaankin perustellusti väittää, että erilaiset ketterien menetelmien sovellutukset ovat…

Implementing Intranet 2.0: A Study of Knowledge Requirements for External Consultants in Enterprise Systems

2014

Published article from the series: Procedia Technology. Also available on Science Direct: http://dx.doi.org/10.1016/j.protcy.2014.10.018 Open Access This paper reports on a case study focusing on intranet implementation projects seen from a consultancy lens. SharePoint is an Intranet 2.0 platform which is a user-centric system based on functionalities adapted from Web 2.0 technologies. Intranet implementation projects are accompanied by a complex socio-technical organizational environment, and require changes in organizational structure and culture. While former studies mainly have focused on challenges seen from the implementing organization's perspective, this study focuses on the experie…

Prosessin kehittämisen rooli julkisen hallinnon IT-hankkeessa : näkökulmana lainsäädäntöprosessi

2015

Tutkielmassa tarkastelen prosessin kehittämistä lainsäädäntöprosessin ja julkisen hallinnon tietotekniikan (IT:n) uudistamisen näkökulmista. Tutkielmassa yhdistyvät toimintaprosessien kehittämisen ja sähköisen julkisen hallinnon tieteellisen tutkimisen näkökulmat. Tarkastelen lainsäädäntöprosessin kehittämistä osana julkisen hallinnon arkkitehtuurikehyksen mukaista toiminta-arkkitehtuuria. Tutkielma on kirjallisuuskatsaus lainsäädäntöprosessin ja sen tietojärjestelmätuen kehittämiseen liittyvään tietojärjestelmätieteen tutkimukseen. Esitän tutkielmassa tuloksia myös liiketaloustieteen ja oikeusinformatiikan ja -lingvistiikan tutkimuksista. Pyrin hyödyntämään aihepiiriin liittyvää laadullist…

Heading at Enabling Settings for Learning

2021

The paper draws on two cases of learning settings that were converted to meet up-to-date educational requirements within these learning contexts. The authors address the role of stakeholder perspectives. Focusing on the learning situation, they present an articulation tool to aid dialogue between key stakeholder perspectives in a (re)design process. Dialogue is a way to figure out relevant issues and to establish the common ground between participants. The goal of a redesign process is that user requirements are well understood, and the design is embedded into local practices, informed of constraints and aware of potential opportunities regarding educational technology.

The metabolism and availability of essential fatty acids in animal and human tissues.

1994

Essential fatty acids (EFA), which are not synthesized in animal and human tissues, belong to the n-6 and n-3 families of polyunsaturated fatty acids (PUFA), derived from linoleic acid (LA, 18:2n-6) and alpha-linolenic acid (LNA, 18:3n-3). Optimal requirements are 3-6% of ingested energy for LA and 0.5-1% for LNA in adults. Requirements in LNA are higher in development. Dietary sources of LA and LNA are principally plants, while arachidonic acid (AA, 20:4n-6) is found in products from terrestrian animals, and eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are found in products from marine animals. EFA are principally present in dietary triacylglycerols, which should be hydrolyze…

U-search: a meta engine for creation of knowledge paths on the web

2010

The main tools used to find digital contents in the Web are search engines and directories but they are not presently able to understand the user specific needs and starting knowledge. This work presents "U-Search" a new meta engine that allows to create knowledge paths on the Web based on specific user requirements and knowledge levels. To this end, we consider different searcher categories such as a "basic searcher" who knows little about a topic and will look for more information, a "deep searcher" who will look for specific details on a topic that he/she already knows and a "wide searcher" who will look for expanding his/her knowledge domain with topics that are loosely related to the s…
