Instructions

Reading digital theses in the closed network of the Aalto University Harald Herlin Learning Centre

In the closed network of Learning Centre you can read digital and digitized theses not available in the open network.

The Learning Centre contact details and opening hours: https://learningcentre.aalto.fi/en/harald-herlin-learning-centre/

You can read theses on the Learning Centre customer computers, which are available on all floors.

Logging on to the customer computers

  • Aalto University staff members log on to the customer computer using the Aalto username and password.
  • Other customers log on using a shared username and password.

Opening a thesis

  • On the desktop of the customer computers, you will find an icon titled:

    Aalto Thesis Database

  • Click on the icon to search for and open the thesis you are looking for from Aaltodoc database. You can find the thesis file by clicking the link on the OEV or OEVS field.

Reading the thesis

  • You can either print the thesis or read it on the customer computer screen.
  • You cannot save the thesis file on a flash drive or email it.
  • You cannot copy text or images from the file.
  • You cannot edit the file.

Printing the thesis

  • You can print the thesis for your personal study or research use.
  • Aalto University students and staff members may print black-and-white prints on the PrintingPoint devices when using the computer with personal Aalto username and password. Color printing is possible using the printer u90203-psc3, which is located near the customer service. Color printing is subject to a charge to Aalto University students and staff members.
  • Other customers can use the printer u90203-psc3. All printing is subject to a charge to non-University members.

Abstract (eng): Light is the most important source of energy and information for plants.
Artificial lighting can be used in greenhouses to enable year-round production and to increase productivity.
The electricity needed for the artificial lighting is a major expense in the Finnish greenhouse production.

The suitability of LED - lighting for greenhouse production and it's advantages over current lighting solutions were investigated in this work.
Major energy savings can be obtained along with increased quality of the plants by using optimised LED - lighting.
The light utilisation of plants can be increased by emphasizing the blue and red wavelengths of the light spectrum.
Currently no LED - based lighting solutions are available for large-scale greenhouse production but due to the on-going research and development major changes in greenhouse lighting can be expected in the near future.
Abstract (fin): Valo on kasvien tärkein energian ja informaation lähde.
Kasvihuoneviljelyssä voidaan keinovalaistuksen avulla pidentää kasvukautta sekä tehostaa tuotantoa.
Keinovalaistuksen vaatima sähköenergia on merkittävä kuluerä suomalaisessa kasvihuoneviljelyssä.

Tässä työssä selvitettiin LED - valaistuksen soveltuvuutta kasvihuoneviljelyyn sekä ledien tuomia etuja nykyisiin järjestelmiin verrattuna.
Ledien avulla on mahdollista päästä merkittäviin säästöihin energiankulutuksessa sekä parantaa sadon laatua optimoimalla valaistus viljeltävän kasvin tarpeiden mukaan.
Painottamalla spektriä sinisen ja punaisen valon aallonpituuksilla saadaan kasvit hyödyntämään valon energiaa tehokkaammin.
Tällä hetkellä markkinoilta ei vielä löydy laajamittaiseen kasvihuoneviljelyyn soveltuvaa lediratkaisua, mutta tutkimus ja tuotekehitys on käynnissä kautta maailman.
Lähivuosina onkin odotettavissa merkittäviä muutoksia kasvihuoneiden valaistusjärjestelmiin.
