26. Distributed control of interconnected systems and its application in traffic control
Sammanfattning : Over the past few decades, the need for mobility and road transportation has been significantly increased over the world. This turned as a dilemma in many metropolitan areas as traffic congestion costs energy and takes time of all individuals who live in big cities. LÄS MER
27. Impact of adjacent dielectrics on the high-frequency performance of graphene field-effect transistors
Sammanfattning : Transistors operating at high frequencies are the basic building blocks of millimeter wave communication and sensor systems. The high velocity and mobility of carriers in graphene can open ways for development of ultra-fast group IV transistors with similar or even better performance than that achieved with III-V based semiconductors.

28. Fibrinolysis and blood loss in major arthroplasty. The effect of tranexamic acid
Sammanfattning : Blood loss in major arthroplasty may be abundant and often necessitates blood transfusions. These may transmit disease and entail an immunological burden to the recipient. After trauma and surgery, the fibrinolytic system reacts with a short period of increased activity, followed by a fibrinolytic shut-down. LÄS MER
29. Laser-based absorption spectrometry : development of NICE-OHMS towards ultra-sensitive trace species detection
Sammanfattning : Laser-based absorption spectroscopy (AS) is a powerful technique for qualitative and quantitative studies of atoms and molecules. An important field of use of AS is the detection of species in trace concentrations, which has applications not only in physics and chemistry but also in biology and medicine, encompassing environmental monitoring, regulation of industrial processes and breath analysis.

30. Maturation of Clay Seals in Deep Bore Holes for Disposal of Radioactive waste : Theory and Experiments
Sammanfattning : KBS-3 and very deep borehole (VDH) concepts are two major types of long-term geologicaldisposal methods for high-level radioactive waste (HLW) isolating from the biosphere. TheKBS-3V concept for isolating the HLW at the depth of 400-500 m, is the officially proposedoption in Sweden and has been the subject of considerable research in the past few decades,while the VDH concept was considered as an option in the 1950s but later became discouragedbecause of insufficient experience in drilling technology.
