1. 1. Mining Futures : Predictions and Uncertainty in Swedish Mineral Exploration

   Författare :Tobias Olofsson; Patrik Aspers; Gholamreza Azarian; Trine Pallesen; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Uncertainty; Risk management; Sociology of the Future; Valuation; Justification; Mineral Exploration; Second Nature; Natural Resources; Sociologi; Sociology;

   Sammanfattning : Any forward-oriented enterprise must somehow manage the challenges posed by uncertainty and with its distant temporal horizons, high stakes, and low probability of success, mineral exploration is a good illustration of this general rule. Based on a combination of interviews, observations, and archival research, this thesis investigates how explorationists use predictions to manage the material complexities and the uncertainties that contribute to determining the future minability of mineral deposits.

3. 2. Spatio-Temporal Data Mining for Location-Based Services

   Författare :Gyözö Gidofalvi; Torben Bach Pedersen; Xiaofang Zhou; Agnès Voisard; Simonas Saltenis; Geomatic ApS - Center for Geoinformatics; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; spatio-temporal data mining; location-based services; location and trajectory anonymization;

   Sammanfattning : Largely driven by advances in communication and information technology, such as the increasing availability and accuracy of GPS technology and the miniaturization of wireless communication devices, Location–Based Services (LBS) are continuously gaining popularity. Innovative LBSes integrate knowledge about the users into the service. LÄS MER

4. 3. From Numerical Sensor Data to Semantic Representations : A Data-driven Approach for Generating Linguistic Descriptions

   Författare :Hadi Banaee; Amy Loutfi; Erik Schaffernicht; Andrey Kiselev; Mobyen Ahmed; Antonio Chella; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Semantic representations; Conceptual spaces; Natural language generation; Temporal rule mining; Physiological sensors; Health monitoring system;

   Sammanfattning : In our daily lives, sensors recordings are becoming more and more ubiquitous. With the increased availability of data comes the increased need of systems that can represent the data in human interpretable concepts. LÄS MER

5. 4. Essays on Development and Politics in Sub-Saharan Africa

   Författare :Jonas Poulsen; Eva Mörk; Niklas Bengtsson; Karl Moene; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; ANC; regression discontinuity; IV; party effects; Rwandan genocide; rainfall; propaganda; social capital; South Africa; mining; resource curse; crime; criminality; Internet; protests; submarine cables; regime change; Africa; employment; light;

   Sammanfattning : Essay I: The African National Congress (ANC) can look back on eighty years of struggle which resulted in the liberation of black Africans, the creation of a democratic constitution and free elections. However, the last twenty years of ANC rule has been criticized for the failure to bring higher living standards for the formerly oppressed. LÄS MER

7. 5. On Data Mining and Classification Using a Bayesian Confidence Propagation Neural Network

   Författare :Roland Orre; KTH; []
   Nyckelord :data mining; bcpnn; classification; neural network;

   Sammanfattning : The aim of this thesis is to describe how a statisticallybased neural network technology, here named BCPNN (BayesianConfidence Propagation Neural Network), which may be identifiedby rewriting Bayes' rule, can be used within a fewapplications, data mining and classification with credibilityintervals as well as unsupervised pattern recognition.BCPNN is a neural network model somewhat reminding aboutBayesian decision trees which are often used within artificialintelligence systems.
