Unsupervised visual object categorization

The number of digital images has been increasing exponentially in the last few years. People have problems managing their image collections and finding a specific image. An automatic image categorization system could help them to manage images and find specific images. In this thesis, an unsupervised visual object categorization system was implemented to categorize a set of unknown images. The system is unsupervised, and hence, it does not need known images to train the system which needs to be manually obtained. Therefore, the number of possible categories and images can be huge. The system implemented in the thesis extracts local features from the images. These local features are used to build a codebook. The local features and the codebook are then used to generate a feature vector for an image. Images are categorized based on the feature vectors. The system is able to categorize any given set of images based on the visual appearance of the images. Images that have similar image regions are grouped together in the same category. Thus, for example, images which contain cars are assigned to the same cluster. The unsupervised visual object categorization system can be used in many situations, e.g., in an Internet search engine. The system can categorize images for a user, and the user can then easily find a specific type of image.

Integration of a Bioethanol Process to a Pulp Mill

Tässä diplomityössä tutkittiin puuhakkeen esihydrolyysi- ja hakkuujätteen hydrolyysiprosessien integroimista sellutehtaaseen bioetanolin tuottamiseksi. Tällaisesta ns. biojalostamosta luotiin WinGEMS-simulointiohjelmalla simulointimalli, jonka avulla tutkittiin bioetanoliprosessin vaikutusta sellutehtaan massa- ja energiataseisiin sekä alustavaa biojalostamon kannattavuutta. Simuloinnissa tarkasteltiin kolmea eri tapausta, joissa mäntysellun tuotannon ajateltiin olevan 1000 tonnia päivässä ja hakkuujätettä käytettävän 10 % tarvittavan kuitupuun määrästä: 1) Puuhakkeen esihydrolyysi ja hakkuujätteen hydrolyysi etanolin tuottamiseksi 2) Puuhakkeen esihydrolyysi, hakkuujäte kuorikattilaan poltettavaksi 3) Ei esihydrolyysiä, hakkuujäte kuorikattilaan poltettavaksi Verrattuna tapaukseen 3, puun kulutus kasvaa 16 % esihydrolysoitaessa puuhake ennen keittoa tapauksissa 1 ja 2. Kasvaneella puun kulutuksella tuotetaan tapauksessa 1 149 tonnia etanolia ja 240 MWh enemmän ylimääräsähköä päivässä. Tapauksessa 2 tuotetaan 68 tonnia etanolia ja 460 MWh enemmän ylimääräsähköä päivässä. Tämä tuottaisi vuotuista lisäkassavirtaa 18,8 miljoonaa euroa tapauksessa 1 ja 9,4 miljoonaa euroa tapauksessa 2. Hydrolyysin tuoteliuoksen, hydrolysaatin, haihduttaminen sekä hydrolyysiprosessien orgaanisten jäännöstuotteiden haihduttaminen ja polttaminen kasvattavat haihduttamon ja soodakattilan kuormitusta. Verrattuna tapaukseen 3, tapauksissa 1 ja 2 haihduttamon vaiheiden määrä on kasvatettava viidestä seitsemään ja tarvittavat lämmönsiirtopinta-alat lähes kaksinkertaistettava. Soodakattilan kuormitus kasvaa 39 % tapauksessa 1 ja 26 % tapauksessa 2.

Fiscal policy and interest rates: the role of financial and economic integration

It is commonly believed that a fiscal expansion raises interest rates. However, these crowding out effects of deficits have been found to be small or non-existent. One explanation is that financial integration offsets interest rate differentials on globalised bond markets. This paper measures the degree of integration of government bond markets, using spatial modelling techniques to take this spillover on financial markets into account. Our main finding is that the crowding out effect on domestic interest rates is significant, but is reduced by spillover across borders. This spillover is important in major crises or in periods of coordinated policy actions. This result is generally robust to various measures of cross-country linkages. We find spillover to be much stronger among EU countries.

Integration of Real-Time Simulator, Motion Platform and Haptics

This thesis describes the process of the integration of a real-time simulator environment with a motion platform and a haptic device as a part of the Kvalive project. Several programs running on two computers were made to control the different devices of the environment. User tests were made to obtain information of needed improvements to make the simulator more realistic. Also new ideas for improving the simulator and directions of further research were obtained with the help of this research.

Implementation and Integration of New Baggage Logistic Centre at HelsinkiVantaa Airport

This thesis deals with improving international airport baggage supply chain management (SCM) by means of information technology and new baggage handling system. This study aims to focus on supply chain visibility in practice and to suggest different ways to improve the supply chain performance through information sharing. The objective is also to define how radio frequency identification (RFID) and enterprise resource planning (ERP) can make processes more transparent. In order to get full benefits from processes, effective business process management and monitoring as well as the key performance indicators must be defined, implemented and visualized through e.g. dashboard views for different roles. As an outcome of the research the need for the use of information technology systems and more advanced technologies, e.g. RFID in the supply chain management is evident. Sophisticated ERP is crucial in boosting SCM business processes and profitability. This would be beneficial for dynamic decision making as well in the airport and airline supply chain management. In the long term, economic aspects support the actions I have suggested in order to make production more flexible in reacting to quick changes.

Effects of neurotrophins on synaptic protein expression in the visual cortex of dark reared rats.

Total lack of visual experience [dark rearing (DR)] is known to prolong the critical period and delay development of sensory functions in mammalian visual cortex. Recent results show that neurotrophins (NTs) counteract the effects of DR on functional properties of visual cortical cells and exert a strong control on critical period duration. NTs are known to modulate the development and synaptic efficacy of neurotransmitter systems that are affected by DR. However, it is still unknown whether the actions of NTs in dark-reared animals involve interaction with neurotransmitter systems. We have studied the effects of DR on the expression of key molecules in the glutamatergic and GABAergic systems in control and NT-treated animals. We have found that DR reduced the expression of the NMDA receptor 2A subunit and its associated protein PSD-95 (postsynaptic density-95), of GRIP (AMPA glutamate receptor interacting protein), and of the biosynthetic enzyme GAD (glutamic acid decarboxylase). Returning dark-reared animals to light for 2 hr restored normal expression of the above-mentioned proteins almost completely. NT treatment specifically counteracts DR effects; NGF acts primarily on the NMDA system, whereas BDNF acts primarily on the GABAergic system. Finally, the action of NT4 seems to involve both excitatory and inhibitory systems. These data demonstrate that different NTs counteract DR effects by modulating the expression of key molecules of the excitatory and inhibitory neurotransmitter systems
