Automatic calibration of numerical model using artificial intelligence based techniques
(Master thesis, 2010)Many energy companies rely on natural resources to produce energy. They use advanced models to estimate how much of those resources they have access to, but if a model is to make an accurate estimation it needs to be ... -
Using hidden Markov models for fault diagnostics and prognosis in condition based maintenance systems
(Master thesis, 2010)Condition Based Maintenance (CBM)) is a concept that has become more and more important as the cost, size, and complexity of mechanical components has increased. As more sensor equipment has become available it has become ... -
An expert system for safety instrumented system in petroleum industry
(Master thesis, 2010)The expert system technology has been developed since 1960s and now it has proven to be a useful and effective tool in many areas. It helps shorten the time required to accomplish a certain job and relieve the workload for ... -
Improving construction site documentation based on cell phone and web technology
(Master thesis, 2010)In many construction companies it is a policy that all the work done on construction sites must be documented. By studying how the pilot customer documents their construction work, we found that their documentation methods ... -
Cooperative retransmission implementation in ns 2
(Master thesis, 2010)From the theoretical perspective cooperative communications are reasonably well understood. But in practical realizations of cooperative communication system are still quite limited, the articles in this special issue ... -
Recommending Services in Pervasive Environments
(Master thesis, 2010)The presence of mobile devices with network connectivity continues to increase in all parts of the world, opening up direct channels to mobile users. The threat of information overload is prevalent, and if not subjected ... -
A novel spatio-temporal scheme for reducing the rate of false positives in bloom filter based URL-caching
(Master thesis, 2010)Achieving efficient use of available resources is an important problem in the field of web mining. Monitoring and analyzing the web is extremely resource demanding, and therefore, more efficient use of resources often ... -
Design a WLAN mini access point in the android platform
(Master thesis, 2010)Mobile as a computing platform is becoming more and more popular. The amount of such devices shipped every year is growing rapidly, more than 1.2 billion in 2009. At the same time the WLAN is being widely adapted at ... -
Gradient descent algorithm incorporating stochastic pointlocation schemes and its application in multidimensional scaling analysis
(Master thesis, 2010)Gradient descent (GD) is a popular approach for solving optimisation problems. A disadvantage of the method is the di culties with choosing a proper learning rate that sets the step size for the algorithm. If the learning ... -
A framework for identity and privacy management on mobile devices
(Master thesis, 2010)More and more online services require user identification. This increases time to fill out extensive forms and results in large amounts of login and identification data to remember. At the same time the number of users ... -
Spam classification for online discussions
(Master thesis, 2010)Traditionally, spam messages filtering systems are built by integrating content-based analysis technologies which are developed from the experiences of dealing with E-mail spam. Recently, the new style of information appears ... -

Uncertainty analysis of hydro-meteorological forecasts
(Master thesis, 2010)Meteorological and hydrological forecasts are very important to human’s life which concerns agriculture, industry, transport, etc. The Nordic hydropower industry use and develop hydrological forecasting models to make ... -
Service virtualization : bringing a remote personal video recorder into a local network
(Master thesis, 2009)Within residential networks digital devices may share information between themselves through several discovery standards such as Bluetooth, Bonjour, or Universal Plug & Play. Similarly, all residential services are ... -
Ad-hoc network for oil supply boats
(Master thesis, 2009)An ad hoc network is a collection of wireless mobile nodes dynamically forming a temporary network without any fixed infrastructure like access points or base stations. Each node in ad hoc network is willing to forward ... -
GPU-accelerated simulation of flow through a porous medium
(Master thesis, 2009)In this thesis we explore the area of general purpose computing on GPU, by looking at how the GPU can be utilized to accelerate transport in reservoir simulations. We implement a general finite volume scheme and a high ... -
Empirical Evaluation of the Bayesian Learning Automaton Family
(Master thesis, 2009)The two-armed bandit problem is a classical optimization problem where a player sequentially selects and pulls one of two arms attached to a gambling machine, and each arm pull results in either a reward or penalty to ... -
Detecting malicious network activity using flow data and learning automata
(Master thesis, 2009)Malicious software has become an increasing problem for both businesses and home users. The traditional antivirus solutions are not always enough to detect an infection. As a result of this a lot of businesses are deploying ... -
Wireless Sensor Networks for Condition Based Maintenance: Security and Reliability
(Master thesis, 2009)In this thesis we present the requirements needed for a Condition Based Main- tenance (CBM) solution by using Wireless Sensor Networks(WSN). The sensor network needs to be secure and reliable to be implemented in a CBM ... -
