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): In this thesis we study merging electronic communications with challenged network systems.
Evolution of data networks has reached a stage where network connectivity is ubiquitous almost everywhere and on almost every device.
Though the abilities of different network connections vary dramatically.
Many are not able to function as parts of the Internet.
Challenged networks are some of the networks where Internet protocols can not function.
The purpose of this work is to develop an interface, and an implementation of that interface, that normal messaging applications can use to communicate over challenged networks.
Email was chosen as the interface because of its flexibility and status as an Internet standard.

As part of this work, an embeddable, reliable and portable software component was implemented, with great focus on the design of the component.
The software was designed to be efficient and straightforward.
During the development, the software was tested for quality and compatibility purposes.
Abstract (fin): Tässä työssä käsitellään sähköisen viestinnän sovittamista erityisvälitysverkkoihin.
Tietoverkkojen kehitys on edennyt asteelle, jossa verkkoyhteyksiä on saatavilla lähes kaikkialla ja lähes kaikissa laitteissa.
Verkkoyhteyksien ominaisuudet kuitenkin vaihtelevat suuresti, ja monet eivät pysty sellaisenaan toimimaan Internetin osina.

Erityisvälitysverkot ovat ympäristöjä, jossa Internetin protokollat eivät enää pysty toimimaan.
Työn päämääränä oli kehittää rajapinta ja sen toteuttava ohjelmistokomponentti, jolla viestintäsovelluksia voidaan sovittaa viestintään haasteellisten verkkojen yli.
Sähköposti valittiin rajapinnaksi sen soveltuvuuden ja standardiaseman vuoksi.

Työssä kehitettiin sulautettava, luotettava ja siirrettävä ohjelmistokomponentti, joten ohjelmiston toteutuksen suunnitteluun kiinnitettiin paljon huomiota.
Ohjelmiston rakenteesta tehtiin tehokas ja suoraviivainen.
Ohjelmiston kehityksen yhteydessä sen toteutusta testattiin ohjelmiston laadun ja yhteensopivuuden varmistamiseksi.
