Feasibility of Software-Based Duty Cycling of GPS for Trajectory-Based Services
No full textEnergy-efficient localization is increasingly important for many types of smartphone apps. The research community has argued that fixed duty cycling of GPS is not a good choice for trajectory-based services concerning route accuracy. In this paper, we describe the design and implementation of a highly accurate map matching and path construction algorithm. Furthermore, with thorough field experiments, we show that fixed duty cycling of a smartphone GPS receiver is a feasible approach for trajectory-based services, and it can achieve considerable energy conservation without sacrificing much route accuracy. When increasing the GPS sampling period beyond 120 seconds, it saves at least 78% energy in comparison to continuous GPS sampling, while the loss of route accuracy tends to be stable around 23%.Li, Xiaohan, Yuan, Fengpeng, & Lindqvist, Janne.

On My Way: Optimizing Driving Routes for Navigation Applications
No full textConventionally, the route recommendations given by GPS navigation applications have been considered as the optimal route search problem only between two locations - origin and destination. Sometimes people want to visit several intermediate locations prior to reaching their final destination. For example, travelers may want to visit a diner and a gas station before arriving at their vacation destination. Although there is likely to be many choices that are available along the route to the destination, only one place from each type should be chosen. Furthermore, in new emerging application domains, such as “physical-world crowdsourcing”, people may want to opportunistically visit some places in order to complete personal or work related tasks. Our work explores a design space where we try to reduce the amount of requests made to third-party map and route data providers. We explore the simple idea of using the Euclidean distance as a rough estimate for the optimal route between destinations with multiple waypoints. Our preliminary results indicate that with over 80% of test cases, this simple Euclidean distance estimator approach gives at least one optimal routing alternative.Yuan, Fengpeng, Song, Xueyuan & Lindqvist, Janne.

Ltd “Janne” financial analysis and forecast for development perspectives
No full textLai uzņēmējdarbība būtu efektīva, nepieciešams veikt finanšu analīzi un attīstības perspektīvu prognozēšanu, kas sniedz finansiālā stāvokļa novērtējumu. Diplomdarba sabiedrības uzņēmējdarbības periods ir 4 gadi, tādēļ finansiālā stāvokļa novērtēšana SIA „Janne” ir nozīmīga. Darba mērķis ir, pielietojot finanšu analīzes un prognozēšanas teorētiskos aspektus analizēt SIA „Janne” finanšu rādītājus un attīstības perspektīvas, un izstrādāt priekšlikumus finansiālā stāvokļa uzlabošanai un attīstībai. Darba izstrādes gaitā autore konstatēja tādas nepilnības kā nesavlaicīga debitoru parādu uzskaite, īstermiņa saistību pārmērīgs apjoms, līdzekļu nepietiekamība un tml., kas skar SIA „Janne” finansiālo stāvokli. Pētījuma gaitā iegūto rādītāju rezultāti liecina par pētāmās sabiedrības līdzšinējās attīstības svārstīgo efektivitāti un nestabilitāti.For business to be effective, it is necessary to make a financial analysis and forecast for development prospects that provides with an assessment of the financial position. The diplomas-work company’s business period is 4 years therefore the assessment of Ltd. “Janne” is important. The aim of the work is, by using the knowledge of financial analysis and forecasting, to analyze company’s financial indicators and development perspectives, to develop proposals for improvement and development of financial position. In the work author identified such shortcomings as untimely accounts receivable accounting, excessive amount of short-term liabilities, insufficient funds, etc., which affects Ltd. “Janne” financial condition. The results obtained during the work indicate the company’s current fluctuating development efficiency and instability
Peter Pohls litterära projekt : en tematisk studie med utgångspunkt i debutromanen Janne, min vän
No full textIn his literary works, the Swedish author Peter Pohl (b. 1940) persistently deals with the issue of friendship which is described as a source of joy and consolation as well as a cause for difficulties and pain. Another common theme in his writing is vulnerability, especially that of children and adolescents, as he regards them as particularly exposed to violence and injustice. Pohl features the act of telling as an important instrument in the process of personal development on many different levels. Finally, his authorship shows that his purpose is to be a spokesman for those who cannot speak for themselves. These four topics which are visible in the main part of his production represent the most important aspects of Pohl's literary project which may be described as a desire to improve the conditions of less privileged groups of society. This thesis deals with the works by Pohl written between 1985 and 2007. In the first chapter, the author is presented. The second chapter is an analysis of his first novel Janne, min vän with a special focus on the above-mentioned themes. Chapter three deals with the novel Malins kung Gurra, a story for young readers that can be looked upon as second, but simpler version of Janne, min vän. In chapter four, the five novels Regnbågen har bara åtta färger, Medan regnbågen bleknar, Vi kallar honom Anna, Vilja växa and Klara papper är ett måste are analyzed and discussed. The last chapter is an attempt at dealing with the remaining books written by Pohl. The aim is to establish whether these works are compatible with the general picture given of Pohl’s literary project

No full textPääurakoitsijan riskin- ja laadunhallinta suuntaporauksessa
No full textOpinnäytetyön tavoitteena oli tarkastella pääurakoitsijan riskien- ja laadunhallinnan toimia suuntaporaustyövaiheessa ja verrata niitä vaatimuksiin case-esimerkin avulla. Aihe opinnäytetyöhön on tullut suuntaporauksen yleistymisen myötä ja halusta tuoda esille työvaiheeseen liittyvää tietoa, sillä aiheesta on saatavilla vain vähän kirjallista materiaalia.
Opinnäyte koostuu riskien- ja laadunhallinnan teoriasta sekä niihin liittyvistä tavoitteista. Lisäksi käsitellään suuntaporaustyön valmisteluun ja toteuttamiseen vaadittavien suunnitelmien laadintaa sekä case-esimerkkiä, jonka avulla toteutunutta riskien- ja laadunhallintaprosessia verrataan teoriaan.
Lopputuloksena on arvio toteutettujen riskien- ja laadunhallintatoimenpiteiden onnistumisesta sekä käytännön toimiin vaikuttaneista tekijöistä. Suuntaporaustyövaiheen jälkeen ei havaittu laatupoikkeamia, eikä työvaiheen aikana sattunut tapaturmia tai läheltä piti -tilanteita. Onnistuneen lopputuloksen varmistamiseksi arvio korostaa teknisen osaamisen, huolellisen suunnittelun sekä hankkeen kaikkien osapuolten tiiviin vuorovaikutuksen merkitystä

Finding a suitable performance testing tool
No full textThe pursuit of finding the most suitable testing software for each project is a difficult task as there are a lot of software effective finding certain kind of problems but completely missing others in the field of stress and load testing. A silver bullet solving all problems in a cost effective and reliable way has not yet been found. This project was done as a systematic literature review to find whether there are solutions documented capable of testing everything in a cost-effective way.
The document starts with an introduction of the task, originating from a real software testing company’s suggestion of finding suitable test software that can, cost effectively and reliably, fulfil the needs of the company. A history section is describing the reason of testing importance, basics of testing and what others have found in their studies of the area. The research method is described in detail followed by results describing tools found during the research divided in sections by license type. The sectioning by license type was selected for the benefit of testing companies that are interested in further developing tools found to their own interest. Findings and answered research questions were presented and discussed followed by possible implications and further research suggestions to future scholars interested in the matter.
The systematic literature review found a total of 40 different tools identified during the data extraction process. One complete software system was available commercially including heavy support and help functions for the customer. A different approach linking open source and relatively inexpensive pieces of software together to achieve a composite solution was also identified. The solution included the most common and most popular individual piece of software identified by the study. All found pieces of software were listed and commented briefly mainly with information originating from the authors’ home pages
