1. 6. Model-based Prognostics for Prediction of Remaining Useful Life

   Författare :Madhav Mishra; Jyoti Kumar Sinha; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance Engineering;

   Sammanfattning : Prognostics and healthmanagement (PHM) is an engineering discipline that aims to maintain the systembehaviour and function, and assure the mission success, safety andeffectiveness. Health management using a proper condition-based maintenance (CBM)deployment is a worldwide accepted technique and has grown very popular in manyindustries over the past decades. LÄS MER

3. 7. Part Quality Prediction and Variation Reduction in Multistage Machining Processes Based on Skin Model Shapes

   Författare :Filmon Yacob; Daniel Semere; Sophie Gröger; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machining simulation; model-based prediction; variation propagation; variation source identification; variation compensation; tolerance analysis; Octree; anomaly detection; quaternion; dual quaternion; Plücker coordinate.; Maskinbearbetningssimulering; modellbaseradförutsägelse; variationsspridning; variationskällidentifiering; variationskompensation; toleransanalys; Octree; dual quaternions; Plücker-koordinat.; Production Engineering; Industriell produktion;

   Sammanfattning : All manufacturing processes inevitably induce variations into manufactured parts that may result in nonconformance. Nonconforming parts incur costs due to the additional process required for rework or scrap loss. Hence, methodical efforts to reduce these variations are necessary for competitive manufacturing.

4. 8. Spatial sampling and prediction

   Författare :Lina Schelin; Sara Sjöstedt-de Luna; Silvelyn Zwanzig; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Auxiliary variables; Censoring; Inclusion probabilities; Kriging; Local pivotal method; Minimum detection limit; Prediction intervals; Representative sample; Spatial process; Spatial sampling; Semiparametric bootstrap; Mathematical Statistics; matematisk statistik;

   Sammanfattning : This thesis discusses two aspects of spatial statistics: sampling and prediction. In spatial statistics, we observe some phenomena in space. Space is typically of two or three dimensions, but can be of higher dimension. LÄS MER

5. 9. Linear Modeling and Prediction in Diabetes Physiology

   Författare :Marzia Cescon; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; system identification; prediction; biological systems;

   Sammanfattning : Diabetes Mellitus is a chronic disease characterized by the inability of the organism to autonomously regulate the blood glucose level due to insulin deficiency or resistance, leading to serious health damages. The therapy is essentially based on insulin injections and depends strongly on patient daily decisions, being mainly based upon empirical experience and rules of thumb. LÄS MER

7. 10. Diabetes Mellitus Glucose Prediction by Linear and Bayesian Ensemble Modeling

   Författare :Fredrik Ståhl; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diabetes; Glucose Prediction; Identification; Ensemble Prediction;

   Sammanfattning : Diabetes Mellitus is a chronic disease of impaired blood glucose control due to degraded or absent bodily-specific insulin production, or utilization. To the affected, this in many cases implies relying on insulin injections and blood glucose measurements, in order to keep the blood glucose level within acceptable limits. LÄS MER
