Hiilinanoputkien käyttö transistorikomponenteissa : hiilinanoputkinäytteiden laadun parantaminen, transistorikomponenttien valmistus sekä niiden sähk…
2011
Puolijohdeteollisuuden kantavana voimana on alusta saakka ollut mikroprosessorien laskentatehon jatkuva kasvu, minkä on sallinut valmistusmenetelmien alituinen tehostuminen. Erityisen merkittävässä osassa on ollut yksittäisten transistorikomponenttien koon pienentyminen, sekä niiden pinta-alatiheyden kasvu substraatilla. On kuitenkin tunnustettu tosiasia, että sama kehitys ei voi jatkua enää pitkään, sillä jo nyt toimitaan nykyisten valmistusmenetelmien fysikaalisilla äärirajoilla. Suotuisan kehityksen turvaamiseksi on siis välttämätöntä ottaa käyttöön kokonaan uusia menetelmiä ja materiaaleja. Tutkielmani liittyy hiilinanoputkien (carbon nanotubes, CNTs) käyttöön sähköisissä komponenteissa…
Kaņepju auga iegūšanas, izplatīšanas, izmantošanas uzturā un medicīniskiem nolūkiem - tiesiskais regulējums Eiropas Savienībā, starptautiskajās tiesī…
2020
Kaņepju augu šķiedra, sēklas, ziedi un lapas jau tūkstošiem gadu ir tikušas izmantotas gan dažādu sadzīves, gan pārtikas produktu pagatavošanai, kā arī medicīniskiem un atpūtas nolūkiem, tomēr daudzu politisku iemeslu dēļ 20.gs vidū daudzviet pasaulē šī auga izmantošana tika aizliegta, jo kaņepju sastāvā tika atklāta viela tetrahidrokanabinols, kas ir psihoaktīva un atkarību izraisoša viela. Turklāt 20.gs. 60.gados kaņepju izmantošanas aizliegumu sāka noteikt starptautiskā līmenī, tomēr vēlāk kaņepes atļāva audzēt šķiedras un sēklu ieguvei, kā arī dārzkopības mērķiem. Neraugoties uz pastāvošajiem ierobežojumiem, interese par kaņepju augiem sabiedrībā nav zudusi, tieši pretēji – palielinājus…

How Do QR Codes Enhance Customer Experience? : Omnichannel Customer Experiences in a Brick-and-Mortar Fashion Store
2023
In this qualitative study, we investigate how customers perceive QR codes enhancing their customer experience (CX) in the brick-and-mortar (B&M) store environment. Introducing QR codes to B&M stores is a part of the larger phenomenon of retailers creating omnichannel CXs by utilizing digital and cyber-physical elements in B&M stores. To collect data from real customers’ CXs, we displayed QR codes in a Finnish fashion brand’s B&M store and interviewed customers who had authentically visited the store. The QR codes displayed in the store were linked to a product information page on the brand’s online store, a brand ambassador’s Instagram posts, and an online survey. The data consist of 15 ind…
Customers’ QR Code Usage Barriers in a Brick-and-Mortar Store : A Qualitative Study
2023
The purpose of this study is to explore the factors that hinder customers from utilizing QR codes when they visit brick-and-mortar (B&M) stores. The research was conducted at a Finnish fashion retailer, where three types of QR codes were displayed for customers to use. In order to identify the barriers that customers face, two different sets of data were collected and analyzed: open-ended survey data (n = 101) and interview data (n = 16). The findings showed two main categories of barriers,customer and company related, with seven sub-barriers. The customer-related barriers included lack of interest in QR codes, user-related usage issues, desire for a device-free B&M store, and dislike towar…
Who are the Showroomers? Socio-Demographic Factors Behind the Showrooming Behavior on Mobile Devices
2022
This quantitative study focuses on socio-demographic variables and their associations with different forms of showrooming behavior. The purpose of this study is to find which consumer groups based on age, gender, and income level are demographically the most probable showroomers, and how much each of these variables explain showrooming. The data used is a structured online survey from 1,028 Finnish omnichannel consumers aged between 18 and 75 years. We compare the means of demographic groups’ shares on different aspects of showrooming, and then use partial least squares structural equation modeling with confirmatory factor analysis to see how much each of the variables explain showrooming. …
The Cross-Channel Effects of In-Store Customer Experience in the Case of Omnichannel Fashion Retailing in Finland
2023
Although omnichannel retailing has emerged as a popular research topic in academic research, there are still gaps in our understanding of this phenomenon. One such gap concerns omnichannel customer experience and particularly the cross-channel or spillover effects of how customer experience in one channel may affect customer behaviour not only in that specific channel but also in the other channels of the same retailer. In this study, we aim to address this gap by examining how customer experience in the offline channel affects customer behaviour in both the offline and the online channel, more specifically how in-store customer experience affects both brick-and-mortar store and online stor…
The importance of online retailers' ethics for traditional, online and multichannel customers
2021
This chapter explores the role of retailers’ ethics in consumer behaviour and channel selection. It is largely acknowledged that many ethical issues in online retailing differ from those of traditional brick-and-mortar retailing. However, there is limited understanding of how ethical considerations vary among consumers that use various shopping channels. Our analysis is based on survey data from traditional shoppers (n = 216), online shoppers (n = 224) and multichannel shoppers (n = 244) in Finland. We firstly examine how these three customer types perceive four key elements of online retailer ethics: security, privacy, non-deception and fulfilment. Secondly, we examine how consumers’ perce…

Methods for space-time parameter estimation in DS-CDMA arrays

Rui Wu tutki väitöstyössään radiokanavan eri ominaisuuksien arviointia. Tietämys radiokanavan ominaisuuksista on monesti välttämätöntä, jotta radiovastaanottimen vastaanottama signaali voidaan purkaa ymmärrettävään muotoon. Wu tutki hajaspektrijärjestelmiä, joissa esimerkiksi puhe- tai datasignaalin kaistanleveys moninkertaistetaan radiolähettimessä. Näin tehdään muun muassa jo toiminnassa olevissa 3G-puhelimissa ja -tukiasemissa. Kaistanleveyden moninkertaistamisella pyritään satunnaistamaan muille järjestelmän käyttäjille aiheutetut häiriösignaalit, koska kyseisissä järjestelmissä signaalit etenevät samalla taajuuskaistalla yhtäaikaisesti. Se, miten kunkin järjestelmän käyttäjän signaali …
