SAMLIC : pilotförsöket
- 2006
-
Reports (other academic/artistic)abstract
- Growing cities are increasing the demand for goods carrying traffic to function well with other traffic. The number of zones for unloading goods in the centre of Linköping is small compared to the number of delivery addresses and the number of goods distributors. The attendant phenomena are congestion and costs of congestion. Therefore the local network for freight forwarders in Linköping has taken the initiative to the SAMLIC project. SAMLIC stands for Coordinated Retail Distribution in Linköping City. The aim of SAMLIC is to create an economically and logistically efficient system for goods distribution that is persistent and friendly to the environment. Economic profitability is neccessary for a system with a joint venture in coordinated distribution. The savings with coordinated distribution for the freight forwarders must be of such a dimension that they find it profitable to join instead of delivering the goods by themselves. During a trial period of nine weeks in the spring of 2004 there was a coordinated distribution to the centre of Linköping. Three freight forwarders took part in this project. The experience of the trial shows that the needed number of trucks decreased by 33 %, the total time for the distribution decreased by 15-20 % and the total driving kilometers in the centre decreased by at least 50 %.

Evaluation of a Laser Doppler System for Myocardial Perfusion Monitoring
- 2007
-
Licentiate thesis (other academic/artistic)abstract
- Coronary artery bypass graft (CABG) surgery is a common treatment for patients with coronary artery disease. A potential complication of CABG is myocardial ischemia or infarction. In this thesis, a method - based on laser Doppler flowmetry (LDF) - for detection of intra- and postoperative ischemia by myocardial perfusion monitoring is evaluated.LDF is sensitive to motion artifacts. In previous studies, a method for reduction of motion artifacts when measuring on the beating heart has been developed. By using the ECG as a reference, the perfusion signal is measured in intervals during the cardiac cycle where the cardiac motion is at a minimum, thus minimizing the artifacts in the perfusion signal.The aim of this thesis was to investigate the possibilities to use the ECG-triggered laser Doppler system for continuous monitoring of myocardial perfusion in humans during and after CABG surgery. Two studies were performed. In the first study, changes in myocardial perfusion during CABG surgery were investigated (n = 13), while the second study focused on postoperative measurements (n = 13). In addition, an ECG-triggering method was implemented and evaluated.It was found that the large variations in myocardial perfusion during CABG surgery could be monitored with the ECG-triggered laser Doppler system. Furthermore, a perfusion signal of good quality could be registered postoperatively from the closed chest in ten out of thirteen patients. In eight out of ten patients, a proper signal was obtained also the following morning, i.e., about 20 hours after probe insertion. The results show that respiration and blood pressure can have an influence on the perfusion signal.In conclusion, the results indicate that the method is able to detect fluctuations in myocardial perfusion under favourable circumstances. However, high heart rate, abnormal cardiac motion, improper probe attachment and limitations in the ECG-triggering method may result in variations in the perfusion signal that are not related to tissue perfusion.
