The Choice of Innovation Policy Instruments

The purpose of this article is to discuss the different types of instruments of innovation policy, to examine how governments and public agencies in different countries and different times have used these instruments differently, to explore the political nature of instrument choice and design (and associated issues), and to elaborate a set of criteria for the selection and design of the instrument

Why precommercial procurement is not innovation procurement

In 2006 the European Commission introduced the concept of "Pre-Commercial Procurement" as an instrument to promote innovation and to mitigate grand challenges. One of the main motivations for the support of Pre-Commercial Procurement schemes was to use public needs as a driver for innovation. This concept was also introduced as a response to the need to reinforce the innovation capabilities of the

Transparency in artificial intelligence

This conceptual paper addresses the issues of transparency as linked to artificial intelligence (AI) from socio-legal and computer scientific perspectives. Firstly, we discuss the conceptual distinction between transparency in AI and algorithmic transparency, and argue for the wider concept ‘in AI’, as a partly contested albeit useful notion in relation to transparency. Secondly, we show that tran

Automatisk skadeklassning av lovtrad i stadsbebyggelse med hjalp av digitaliserade IR-fargflygbilder

In August 1986 some parks in central Malmo were photographed from a height of 760 meters with colour infrared film. Two simultaneous studies were performed to evaluate the feasibility of manual and digital classification of trees with different degrees of crown damage. This damage is mostly due to exhaustion fumes from heavily trafficked roads, mechanical damage to roots and de-icing salt. This pa

Tillförlitlig global vegetationsinformation fran satellitdata-optimism eller realitet?

The continuous operation of the NOAA series of meteorological satellites from the early 1980s onward, and the use of time series of data from its AVHRR sensor have been instrumental in the development of a new paradigm in the area of global earth observation. The coarse spatial and high temporal resolution of the data contrasts sharply with the data characteristics of traditional earth resource sa

Analysing vegetation changes in the Sahel using sensor data from Landsat and NOAA

The semi-arid Sahel zone of Africa has suffered several periods of severe drought since about 1950. We have analyzed AVHRR Normalized Difference Vegetation Index (NDVI) over the Sahel for the period 1982-2002, and found extensive areas of increasing NDVI. To verify these changes we have analyzed Landsat TM and ETM+ scenes from 1984-1986 and 1999-2001 for areas in the Sudan, Central African Republi

Mapping NPP for a coniferous forest in southern sweden using data from Terra/MODIS

Net primary production (NPP) is modeled for a coniferous forest in southern Sweden for 2001. The model is based on the light-use efficiency concept where NPP is calculated as a product of absorbed photosynthetically active radiation (APAR) and a light-use efficiency factor (ε). APAR is estimated from the fraction of APAR (FAPAR) multiplied with the daily total amount of incoming PAR. FAPAR is obta

Variation of satellite estimated LAI due to the impact of the ground vegetation cover

The contribution of the understorey vegetation to the spectral reflectance from the top of a forest canopy was investigated by the use of a forest canopy reflectance model. Detailed field data, i.e. forest leaf area index (LAI), tree structural parameters like the height, diameter and crown length of the trees, and the composition, distribution and reflectance of the forest floor, was collected fo

High resolution mapping of vegetation dynamics from Sentinel-2

The aim of this work is to develop and test a method for generation of information on vegetation dynamics from high-spatial resolution data, such as Sentinel-2. In order to accomplish this, Sentinel-2 data were simulated from existing SPOT HRG and HRVIR scenes over Sweden. We used TIMESAT, a well-tested computer package for generating smooth seasonal profiles and generation of seasonality paramete

Insamling av geografiska data

Summary: Geografisk informationsbehandling baseras på insamling, lagring, analys och visualisering av geografiska data. Denna indelning utgör också grunden för bokens disposition. Boken är i första hand avsedd för introducerande kurser vid universitet och högskolor men vissa delar är lämpliga även på avancerad nivå. Den är också utmärkt för yrkesverksamma inom GIS som vill öka sina teoretiska kuns
