En multipel linjär regression
In this study a multiple linear regression was carried out in the interest of analysing a number of variables effect on the final prices of apartments in Stockholm’s inner districts. The result may be employed to predict and observe percentage changes on the final price of …
Sparse matrices are often used in numerical algorithms that solve linear equation systems. Many methods for storing sparse matrices have been proposed and implemented during the years. These methods focus primarily on minimizing the total memory consumption and the time that it …
Examensarbetet använder generaliserade linjära modeller för att identifiera och analysera enhetsspecifika egenskaper som påverkar risken för operativa förluster. Företag exponeras sällan mot operativa förluster vilket gör att det finns lite information om dessa förluster. De …
… that sample basis method is the most accurate, fast and reliable method to linearize a PA. The PA1 proved to be easier than the DPA to linearize, except for when being close to saturation where better IMD-suppression was achieved with the DPA. ADS is clearly able to simulate …
Under tillverkningsprocessen i massa- och pappersindustrin bildas avloppsflöden i flera olika steg. Ett av de miljöbelastande utsläppen utgörs av organiskt material. Organiskt material kan mätas som biokemisk syreförbrukning (BOD), kemisk syreförbrukning (COD) eller som totalt …
En jämförande studie mellan yngre och äldre sjukksöterskor
… The sample constituted of 60 employed nurses. Chi2 analysis, ANOVA, t-test and linear regression analyses were conducted in SPSS (22,0). Result: Nurses had a relatively high intrinsic work motivation. Autonomy (M = 4,73) was estimated significantly lowest. Moreover, autonomy was …
… movement and duration variables and masticatory efficiency. Significant linear relationship was found between jaw movement sideways and masticatory efficiency. Descriptive analysis of the chewing pattern and the pattern for side changes was also made. The results of the present …
… company Sandvik Coromant has a positioning table which task is to move an item linearly. The positioning table has a linear motor capable of high velocity and acceleration. This makes it possible to achieve short cycle times and a more profitable production. The purpose of this …
… as close as 10-20 cm above the char on the pine trunks. There was a positive linear relation between the height of the lowest surviving lichen and both the height of the surviving needles in the crown and the height of the soot. The lowest surviving needles were always …
Extensively kept animals for meat production have the right to live in a good environment. Cattle (Bos Taurus) as social animals live in small herds in the wild. When holding animals extensively new problems have arisen regarding human ? animal interactions. One welfare problem …
… where magnetite clearly was the source of the remanence, and an other with a linear decrease in magnetization intensity. The measurements of magnetic anisotropy reveals a magnetic fabric with an almost horizontal foliation and a lineation that indicates a fairly uniform NNW/ …
… but refraction is still changing and slowly progressing toward myopia. A non-linear, mathematical model was developed to show the development of the refractive status based on the data obtained in our study.
A comparison between EPICS XL and Celldyn Sapphire
… was high for both EPICS XL (?2.5%) and Celldyn (?10%). The method was linear over a wide range. Comparisons of CD3+, CD4+, and CD8+ T-lymphocytes analysis showed high coefficients of correlation (r?0.9) and agreement (y>0.9x) between two instruments. A lower degree of agreement …
… natural changes like climate change. Climate change is a complex, dynamic,non-linear process with a great deal of uncertainty concerning the time perspective, risks andconsequences. A combination of factors like climate change, geographical vulnerability, adensely populated and …
Arbetet har utförts på Saab Bofors Dynamics i Karlskoga och dess syfte var att undersöka om det är möjligt att använda modellbaserad prediktionsreglering, MPC, vid slutfasstyrning av en viss typ av robot. Som referensram används linjärkvadratisk reglering, LQ, eftersom denna …
