1. 26. The road to an accurate cost estimation in engineer-to-order manufacturing - A case study of cost estimation accuracy within advanced technology development in a defence and security company

   Master-uppsats, Göteborgs universitet/Graduate School

   Författare :Lawin Anwar; Sandra Barría Colliander; [2023-07-03]
   Nyckelord :Engineer-to-order; new product development; cost management; cost engineering; cost estimation error; cost overruns; cost estimation accuracy; project management;

   Sammanfattning : Estimating the costs of a project is a vital part of manufacturing organisations as estimations are what set the basis for the price of the products. Precise estimates allow for effective planning and resource allocation, ensuring that the necessary materials, equipment, and personnel are available to complete the project on time and within budget.

3. 27. Volatility Forecasting - A comparative study of different forecasting models.

   Kandidat-uppsats,

   Författare :Emil Sturesson; Anton Wennström; [2023-06-29]
   Nyckelord :Volatility; GARCH; EGARCH; t-GAS; HAR-RV; Realized GARCH; Volatility Forecasting; Volatility Modelling;

   Sammanfattning : This study evaluates the out-of-sample forecasting performance of different volatility mod- els. When applied to XACT OMXS30, we use GARCH(1,1), EGARCH(1,1), and t- GAS(1,1) to forecast squared daily returns while Realized GARCH(1,1) and HAR-RV are used to forecast Realized Variance. LÄS MER

4. 28. Forecasting Volatility of Ether- An empirical evaluation of volatility models and their capacity to forecast one-day-ahead volatility of Ether

   Master-uppsats, Göteborgs universitet/Graduate School

   Författare :Johannes Marmdal; Adam Törnqvist; [2023-06-29]
   Nyckelord :Forecast; Volatility; Ether; GARCH; EWMA; SMA;

   Sammanfattning : This study evaluates the performance of volatility models in forecasting one-day-ahead volatility of the cryptocurrency Ether. The selected models are: GARCH, EGARCH, GJR-GARCH, SMA9, SMA20, and EWMA. We investigate both in-sample performance and out-of-sample performance. LÄS MER

5. 29. IDENTIFICATION OF ENVIRONMENTALLY RELEVANT BENTHIC FORAMINIFERA FROM THE SKAGERRAK FJORDS BY DEEP LEARNING IMAGE MODELING

   Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Författare :Marko Plavetic; [2023-06-26]
   Nyckelord :benthic foraminifera; deep learning; environmental monitoring; YOLOv7;

   Sammanfattning : Over the several past decades, there has been increasing interest in using foraminifera as environmental indicators for coastal marine environments. As compared to macrofauna, which are currently used in environmental studies, foraminifera offer several distinct advantages as bioindicators, including short generation times, a high number of individuals per small sample volume, hard and durable tests with high preservation potential, and low cost of sample extraction.

7. 30. Stavningstesten ur LäSt och DLS 2 - en jämförelse av språklig konstruktion och mellanstadieelevers stavfel

   Magister-uppsats, Göteborgs universitet/Institutionen för neurovetenskap och fysiologi

   Författare :Diana Shah Ebrahim; Semina Zahirović; [2023-06-20]
   Nyckelord :DLS2; LäSt; stavning; mellanstadieelever; stavningskompetenser;

   Sammanfattning : Föreliggande studie undersökte i vilken utsträckning Diagnostiska läs- och skrivprov (DLS) samt Test i läsning och stavning (LäSt) mäter olika stavningskompetenser, hur elevernas testresultat från båda testen överensstämmer med varandra, och vilka stavfel som är vanliga bland mellanstadieelever. Deltagarna var 18 elever fördelade mellan årskurserna 4 och 5. LÄS MER
