Online drawings for dementia diagnose: in-air and pressure information analysis

In this paper we present experimental results comparing on-line drawings for control population (left and right hand) as well as Alzheimer disease patients. The drawings have been acquired by means of a digitizing tablet, which acquires time information angles and pressures. Experimental measures based on pressure and in-air movements appear to be significantly different for both groups, even when control population performs the tasks with the non-dominant hand.

Effects of the 80 km/h and variable speed limits on air pollution in the metropolitan area of Barcelona

In 2008 the regional government of Catalonia (Spain) reduced the maximum speed limit on several stretches of congested urban motorway in the Barcelona metropolitan area to 80 km/h, while in 2009 it introduced a variable speed system on other stretches of its metropolitan motorways. We use the differences-in-differences method, which enables a policy impact to be measured under specific conditions, to assess the impact of these policies on emissions of NOx and PM10. Empirical estimation indicate that reducing the speed limit to 80 km h-1 causes a 1.7 to 3.2% increase in NOx and 5.3 to 5.9% in PM10. By contrast, the variable speed policy reduced NOx and PM10 pollution by 7.7 to 17.1% and 14.5 to 17.3%. As such, a variable speed policy appears to be a more effective environmental policy than reducing the speed limit to a maximum of 80 km/h.

Työpöytäsovellus Adobe Air -tekniikalla

Työn kirjallinen osuus aloitettiin kertaamalla lyhyesti web-sovellukset ja niiden ominaisuudet. Tekniikan kehittyminen on mahdollistanut rikkaat Internet-sovellukset, joiden periaate ja toiminta esitettiin, ja lisäksi perehdyttiin rikkaiden Internet-sovellusten vaatimuksiin. Adobe Air on käyttöjärjestelmäriippumaton ajoympäristö työpöytäsovellusten toteuttamiseen web-tekniikoilla. Air-tekniikkaan tutustuttiin käymällä läpi ajoympäristön tärkeimmät komponentit ja niiden merkitys sekä Air-sovelluksen tietoturvamalli. Air-sovellus voidaan toteuttaa vaihtoehtoisilla sovellustekniikoilla, jotka esitellään lyhyesti ja pohditaan valintaan vaikuttavia ominaisuuksia. Lisäksi esitettiin sovelluskehitykseen tarjolla olevia työkaluja ja Air-sovelluskehityksen ominaispiirteitä.Työssä toteutettiin Asiakasselain-sovellus, jonka on tarkoitus korvata tulevaisuudessa tällä hetkellä käytössä oleva Asiakaspääte-sovellus. Asiakasselaimen avulla asiakas voi etsiä tuotteita ja lisätietoja tavarataloissa. Air-sovelluksen sovellustekniikaksi valittiin HTML/Ajax-tekniikka. Sovellus hyödyntää tavaratalon varasto-tietokantaa sekä verkko-kaupan kuva- ja tuoteinformaatiota. Työn päätavoitteena oli tutustua Adobe Air -tekniikkaan ja sen tarjoamiin mahdollisuuksiin. Air osoittautui mielenkiintoiseksi ja helpoksi vaihtoehdoksi työpöytäsovelluksen toteutta-misessa perinteisillä web-tekniikoilla.

Price differences between domestic and international air markets : an empirical application to routes from Gran Canaria

In this paper we examine whether airline prices on national routes are higher than those charged on international routes. Drawing on a database prepared specifically for this study, we estimate a pricing equation for all routes originating from Gran Canaria, Canary Islands, Spain; differentiating between national and international routes. A key difference between these two route types is that island residents benefit from discounts on domestic flights. When controlling for variables related to airline characteristics, market structure and demand, we find that national passengers who are non-residents on the islands are paying higher prices than international passengers.

Developing service offering of an air freight carrier

The thesis examined service offering development of an air freight carrier from the customers' point of view. The study was limited to the biggest business clients of the carrier. Service offering development can be divided into service concept, process and system. The thesis was based on these three themes and quality. Compared to product development, systematic and well-structured service development has been studied little, especially in business market. However, service development is a current issue. Due to growing competition companies should carefully listen to their clients' needs and respond to them by offering right services. Methodology of the thesis is qualitative and representatives of three forwarding companies were interviewed. It was found out that the forwarding companies consider themselves as partners of the airline. In addition to general reliability, the customers value the most fluent terminal processes and electronic communication.

Life cycle costs in heating, ventilation and air-conditioning systems with drive

Energy consumption and energy efficiency have become an issue. Energy consumption is rising all over the world and because of that, and the climate change, energy is becoming more and more expensive. Buildings are major consumers of energy, and inside the buildings the major consumers are heating, ventilation and air-conditioning systems. They usually run at constant speed without efficient control. In most cases HVAC equipment is also oversized. Traditionally heating, ventilation and air-conditioning systems have been sized to meet conditions that rarely occur. The theory part in this thesis represents the basics of life cycle costs and calculations for the whole life cycle of a system. It also represents HVAC systems, equipment, systems controls and ways to save energy in these systems. The empirical part of this thesis represents life cycle cost calculations for HVAC systems. With these calculations it is possible to compute costs for the whole life cycle for the wanted variables. Life cycle costs make it possible to compare which variable causes most of the costs from the whole life point of view. Life cycle costs were studied through two real life cases which were focused on two different kinds of HVAC systems. In both of these cases the renovations were already made, so that the comparison between the old and the new, now existing system would be easier. The study indicates that energy can be saved in HVAC systems by using variable speed drive as a control method.
