Digitizing data acquisition and time-of-flight pulse processing for ToF-ERDA
2016
A versatile system to capture and analyze signals from multi channel plate (MCP) based time-of-flight detectors and ionization based energy detectors such as silicon diodes and gas ionization chambers (GIC) is introduced. The system is based on commercial digitizers and custom software. It forms a part of a ToF-ERDA spectrometer, which has to be able to detect recoil atoms of many different species and energies. Compared to the currently used analogue electronics the digitizing system provides comparable time-of-flight resolution and improved hydrogen detection efficiency, while allowing the operation of the spectrometer be studied and optimized after the measurement. The hardware, data acq…
A simple timestamping data acquisition system for ToF-ERDA
2015
A new data acquisition system, ToF-DAQ, has been developed for a ToF-ERDA telescope and other ToF-E and ToF-ToF measurement systems. ToF-DAQ combines an analogue electronics front-end to asynchronous time stamped data acquisition by means of a FPGA device. Coincidences are sought solely in software based on the timestamps. Timestamping offers more options for data analysis as coincidence events can be built also in offline analysis. The system utilises a National Instruments R-series FPGA device and a Windows PC as a host computer. Both the FPGA code and the host software were developed using the National Instruments LabVIEW graphical programming environment. Up to eight NIM ADCs can be han…

Ristivetoa : tapaustutkimus suomalaisesta koneenrakennusverkostosta
2008
Menestyvien tuotteiden kehittäminen edellyttää innovaatioita ja niiden hyödyntämistä. Tämän esitutkimuksen pyrkimyksenä oli hahmottaa metsäklusterin koneenrakennuksen liiketoimintaverkostoja ja toiminnan luonnetta veturiyrityksen, teknologiayritysten ja pääomasijoittajien näkökulmasta. Tunnistimme haastatteluiden avulla 3 haastavaa ongelmakohtaa, jotka tulisi ratkaista verkoston innovatiivisuuden kehittämiseksi: 1) immateriaalisista oikeuksista sopiminen verkoston jäsenten kesken, 2) rajanveto partneruuden ja kilpailutuksen välillä, sekä 3) keinot joilla edesautetaan järjestelmätoimittajia sitoutumaan ja toisaalta säilyttämään riippumattomuuden päämiehestään. Ehdotamme jatkotutkimushankkeen…

Asiakkaiden sitouttaminen mobiilipalveluihin
2015
Pystytäänkö asiakkaiden sitoutumiseen mobiilipalveluihin vaikuttamaan? Ny-kyään on erittäin tärkeää luoda hyviä asiakassuhteita. Moni kuluttaja on käy-tännössä ”kyllästetty” mainonnalla. Yksi tehokkaimpia tapoja oman yrityksen markkinointiin on erinomaiset asiakassuhteet. Erinomaisten asiakassuhteiden luomiseksi on erityisen tärkeää tarjota asiakkaille heidän haluamansa palvelut. Mobiilipalveluiden käyttäminen on lähtenyt räjähdysmäisesti kasvuun, josta voidaankin päätellä, että asiakkaiden sitouttaminen juuri niihin on erityisen tärkeää. Tähän kysymykseen haen vastausta kandidaatintutkielmassani, jonka toteutan kirjallisuuskatsaukselle tyypilliseen tapaan. Asiakkaan sitouttamisen ympärille…
Initial Coin Offering (ICO) as a Fundraising Strategy : A Multiple Case Study on Success Factors
2019
Cryptocurrencies and Initial Coin Offerings (ICO) are some of the more prominent examples of currently used blockchain technology applications. Especially software startups have leveraged ICOs to gain funding early on in their lifecycles, going on to develop and create new blockchain based applications. Recently, larger companies such as Facebook have also begun to show interest in cryptocurrency, although thus far not for funding purposes in the form of ICOs. In this paper, we investigate factors that positively affect the abilities of companies to meet their fundraising goals via ICOs. We first identify a set of factors from extant literature and then seek to further confirm the effect of…
Financial aspects of business models : reducing costs and increasing revenues in a cloud context
2018
The emergence of cloud computing induces opportunities for software vendors and for organizations with great storage needs. Indeed, software companies have begun to adopt cloud technologies and offer their software as a service to customers instead of selling software products. As a result, their revenue models have changed, and the diversity and complexity of the resulting pricing models have created both opportunities and impediments to competition in the market. On the other hand, due to the exponentially growing volume of digital content, organizations have an increasing demand for storage and need to choose between private, public, and hybrid storage solutions. This decision requires c…

Etic and emic data production methods in the study of journalistic work practices : A systematic literature review
2023
This methodological paper discusses the application of etic and emic perspectives in producing data sets for the study of journalistic praxis. The concepts refer to the researcher-analyst’s and the practitioner-informant’s viewpoints, respectively, and that being the case, they have inherent weaknesses if used independently. We argue that these shortcomings can be mitigated through an integrated application of the concepts and by seeing the two perspectives as complementary to each other. Combining etic and emic perspectives will allow for a more comprehensive understanding of complex yet routinized real-life behaviour such as journalistic work. Following the appraisal of the etic-emic comb…
