1. 6. Onboard condition monitoring of vehicle-track dynamic interaction using machine learning : Enabling the railway industry’s digital transformation

   Författare :Rohan Kulkarni; Mats Berg; Ulf Carlsson; Alireza Qazizadeh; Sebastian Stichel; Jordi Viñolas; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active preventive maintenance; intelligent fault diagnosis; anomaly detection; vehicle fleet; track irregularities; vehicle hunting; wheel-rail interface.; Farkostteknik; Vehicle and Maritime Engineering;

   Sammanfattning : The railway sector’s reliability, availability, maintainability, and safety (RAMS) can significantly improve by adopting condition based maintenance (CBM). In the CBM regime, maintenance decisions are driven by condition monitoring (CM) of the asset. LÄS MER

3. 7. Development of life cycle cost model and analyses for railway switches and crossings

   Författare :Arne Nissen; Ajit Kumar Verma; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

   Sammanfattning : Infrastructure managers need to have a safe and available infrastructure, so that train operators can deliver a transport product at an affordable price. In the future, as traffic volume increases, higher utilisation of the existing capacity, less time for maintenance and fewer unplanned interruptions will be critical for meeting the ever increasing need of transport capacity.

4. 8. Interfacing HPLC with MALDI- and ESI-MS for Automated High Sensitivity Analysis of Proteins and Peptides

   Författare :Tasso Miliotis; Lund Institutionen för kliniska vetenskaper; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; automated; phosphorylation; ZAP-70; peptides; proteins; comprehensive; multidimensional; two-dimensional; piezoelectric; microdispenser; flow-through; ESI-MS MS; Capillary HPLC; MALDI-TOF MS; Analytical chemistry; Analytisk kemi;

   Sammanfattning : The research described in this thesis has an interdisciplinary approach dealing with chemical, biological, and technical issues. One objective was to interface miniaturized liquid chromatography (LC) to mass spectrometry, i.e. MALDI-TOF MS and ESI-MS, in an unattended mode for high sensitivity determination of proteins and peptides.

5. 9. Direct injection of plasma samples into restricted-access media precolumns for drug analysis in column-switching systems

   Författare :Zuoxiang Yu; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi; analytisk farmaceutisk kemi; Analytical Pharmaceutical Chemistry;

   Sammanfattning : This thesis focuses on the theoretical and practical aspects of using column-switching systems for direct injection of plasma samples to assay drugs at ng/ml levels. The systems utilized a restricted-access media (RAM) precolumn for the sample clean-up and trace enrichment. LÄS MER

7. 10. Staging the world. Rome and the other in the triumphal procession

   Författare :Ida Östenberg; Antikens kultur och samhällsliv; []
   Nyckelord :HUMANIORA; HUMANITIES; world mastery; kings; barbarians; conquest; aerarium; wealth; triumphator; representations; captives; spoils; enargeia; spectators; display; role-playing; processional sequence; self-definition; the other; ritual; performance; Rome; triumphal procession; oikumene.; Ancient history; Antikens och forntidens historia;

   Sammanfattning : The triumphal procession staged Roman conquest and supremacy, featuring the defeated ‘other’ as opposed to the victorious ‘self’ in a rather fixed role-playing. This thesis takes as its theoretical premise that these ritually recurrent and visually emphatic processions both conveyed and constructed Roman views of the self and the other, and that they can be studied as formative expressions of such conceptions.
