Detecting explosive substances by the IR spectrography

2014

Fast and safe detection methods of explosive substances are needed both before and after actualized explosions. This article presents an experiment of the detection of three selected explosives by the ATR FTIR spectrometer and by three different IR hyperspectral imaging devices. The IR spectrometers give accurate analyzing results, whereas hyperspectral imagers can detect and analyze desired samples without touching the unidentified target at all. In the controlled explosion experiment TNT, dynamite and PENO were at first analyzed as pure substances with the ATR FTIR spectrometer and with VNIR, SWIR and MWIR cameras. After three controlled explosions also the residues of TNT, dynamite and P…

Hyperspectral imaging based biomass and nitrogen content estimations from light-weight UAV

2013

Hyperspectral imaging based precise fertilization is challenge in the northern Europe, because of the cloud conditions. In this paper we will introduce schemes for the biomass and nitrogen content estimations from hyperspectral images. In this research we used the Fabry-Perot interferometer based hypespectral imager that enables hyperspectral imaging from lightweight UAVs. During the summers 2011 and 2012 imaging and flight campaigns were carried out on the Finnish test field. Estimation mehtod uses features from linear and non-linear unmixing and vegetation indices. The results showed that the concept of small hyperspectral imager, UAV and data analysis is ready to operational use.

Coupling high-resolution satellite imagery with ALS-based canopy height model and digital elevation model in object-based boreal forest habitat type …

2014

We developed a classification workflow for boreal forest habitat type mapping. In object-based image analysis framework, Fractal Net Evolution Approach segmentation was combined with random forest classification. High-resolution WorldView-2 imagery was coupled with ALS based canopy height model and digital terrain model. We calculated several features (e.g. spectral, textural and topographic) per image object from the used datasets. We tested different feature set alternatives; a classification accuracy of 78.0 % was obtained when all features were used. The highest classification accuracy (79.1 %) was obtained when the amount of features was reduced from the initial 328 to the 100 most imp…

Itsemurhan taide : itsemurhan roolit modernissa ja jälkimodernissa taiteessa

2011

Tutkielma kartoittaa itsemurhan esiintyvyyttä modernissa ja jälkimodernissa taiteessa ja pyrkii luomaan typologian niistä erinäisistä rooleista, joissa itsemurhan representaatio tällä reilun sadan vuoden aikajanalla esiintyy. Itsemurhan näkyvyydestä taiteessa tehty aiempi tutkimus on vähäistä ja painottuu modernismia edeltäneeseen taiteeseen, joten tutkielma pyrkii muodostamaan kokonaiskuvaa niukasti tutkitusta aihepiiristä. Tutkimuksen taustalla on ajatus siitä, että taide mahdollistaa itsemurhan kaltaisen tabun käsittelyn tavalla, jota arkikieli ei tue. Siten "itsemurhan taidetta" tarkastelemalla olisi mahdollista nähdä myös itsemurhaan liitettyjä merkityssisältöjä laajemmassakin, kulttuu…

Efficiency of Corporate Income Tax Reliefs for the Investment Promotion in Latvia

2014

Corporate income tax rate in Latvia is one of the lowest in the European Union and is favourable for business. However, the government additionally uses numerous CIT reliefs to stimulate investments, to promote specific industries and investors. Total costs of these tax reliefs are high, but many of the goals declared by their introduction are not reached, suggesting that tax relief efficiency could be questioned. The efficiency of the existing and potential CIT reliefs should be regularly evaluated. The suggested criteria for such examination are – clear objective, type of taxable rent, existence of positive externality, appropriate design and potential for tax planning, costs in revenue f…

Tecniche antisismiche nella Sicilia di età moderna

2012

Nella Sicilia d'età moderna ricorrono spesso esempi dove le ragioni strutturali, in relazione ai dibattiti incentrati sugli effetti disastrosi di numerosi eventi sismici che hanno interessato l'isola in particolare dal Cinquecento al Settecento, condizionano e spiegano alcune scelte formali attuate nell'architettura monumentale.

Terremoti e ricostruzioni tra XVII e XVIII secolo

2012

Il volume è relativo agli atti dei Seminari internazionali tenuti a Lisbona (10 ottobre) e a Noto (24 ottobre)nel 2008. In particolare l'opera contiene saggi di autori nazionali e internazionali inerenti ricerche sulle ricostruzioni dopo i terremoti avvenuti tra Seicento e Settecento in Sicilia e a Malta (1693 Val di Noto; 1726 Palermo; Messina 1783) e a Lisbona (1755)

Incremental innovation and the utility model

2016

Tutkielmassa tarkastellaan taloudellisen kasvun tärkeintä komponenttia: teknologiaa. Tarkoituksena on määrittää inkrementaalisen innovaation tarkka sijainti innovaatiotypologiassa ja kirjallisuudesta syntetisoidussa teknologian elinkaari-mallissa. Selviää, että yksittäisen teknologian kehitystä voidaan ajatella jatkumona, jolla on vaikutuksia tutkimusprosessin luonteeseen, ja sitä kautta myös markkinarakenteeseen. Tässä kontekstissa inkrementaaliset innovaatiot ovat innovaatioita kuvitellun artefaktin periferisissä komponenteissa, mikä tarkoittaa käytännössä sitä, että ne yleensä seuraavat dominanttia mallia (dominant design). Nämä kaksi konseptia ovat siis sidoksissa toisiinsa. Teoreettise…
