… the ML estimators are consistent and asymptotically unbiased and that the standard errors are asymptotically correct. Thus the situation is comforting for large sample sizes. What is not clear is how the ML estimator performs in not-quite-large samples. Object of the present …
… Guidelines for the preparation and verification of DTM are found in Swedish Standards Institute ? Technical Specifications (SIS-TS) 21144:2007 and SIS-TS 21145:2007. These were defined in collaboration between Swedish National Rail Administration, Banverket, and Swedish Road …
… devoted to analyze titanium, to find the best titanium compound for producing standards. The work has been performed using literature studies and many experiments in the laboratories at SECO Tools inFagersta,Sweden. This project has included about ten working weeks. In this …
Rekommenderade avsteg från IEC 60076 för att vid upphandling beskriva en robust enhet
… of this M.Sc. thesis is to investigate if deviations should be made from the standard IEC 60076 ? Power Transformers in order to describe a robust large power transformer for procurement. The investigation has been conducted in three stages. In the first stage a definition of …

… 0?4 s and various losses of correction data have generally small impact on the standard uncertainty values ??in latitude and longitude. The standard uncertainty in height is 1.5?2 times higher than it is in plane. The impact of the baseline length is not significant, a marginal …
… water on the other hand has been overestimated up to 57 %. One reason is high standard values when calculating.The whole difference does not necessarily depend on miscalculations. Errors can also occur when separate measurement of hot water is not available and an assessment …
… showed, in comparison with the rest of the substances as a whole, an increased standard deviation in heart rate (p
… report data such as velocity (U), turbulent kinetic energy (k) and standard deviation (URMS) have been obtained and have formed the basis for comparison. The models have been simulated in two different software programs: OpenFOAM and Fluent. The data have thereafter been post …
… on animal housings. If the housing does not meet up with the legislation standards the county administrative boards can issue injunctions to the responsible person. If this person does not agree with the injunctions it can be appealed. In this study the aim was to investigate if …
En studie i hur finansiell risk bör förmedlas
… facilitate when an individuals risk profile is ascertained. We have found that standard deviation is the risk concept that dominates in financial theory, and together with Value at Risk is the most common used in practise. Good knowledge about risk is required when explaining …
… The average milk yield during the experiment was 29,9 kg/cow/day with a standard deviation of 1,4 kg/cow/day. The DSS predicted a milk yield of 30,8 kg/cow/day in grazing calendar 1 and 31,5 kg/cow/day in grazing calendar 2. The standard deviation was 0,7 kg/cow/day in both …
… therefore we use a weighted regression model to estimate variance and standard deviation. A control diagram, aims to control the production during the process. This could be done with either the mean value or the absolute value of the difference between the extreme values, R. A …
en bra naturvårdsåtgärd för att bevara enskilda arter och/eller bevara den biologiska mångfalden?
… whether it is in the nature reserve forests or non protected forests. But the standard deviation differed between the forests (nature reserve and non protected forests) on the incidences (nature reserve SD = 7.43, non protected forest SD = 0.31) and the abundance (nature reserve …
Ett säkrare val för investeraren
… In addition evaluation was done by calculation of financial variables, the standard deviation, total return, average return, Sharpe ratio and a comparison of the funds yields with yields from similar funds in the same region. Result shows high yields from the fund invested in …
? Utveckling av en fyrtakts förbränningsmodell för att prediktera optimala ventilinställningar
… and the result is a model that, for the current data set, predicts IMEP with a standard deviation of 4.9% for the relative error. The corresponding relative error standard deviation for PMEP estimation is 8.8%. With this model accuracy, an optimization routine for looping …
