2. 1. Business Value Assessment of IT Investments : An Evaluation Method Applied to the Electric Power

   Author : Magnus Gammelgård; Tosten Cegrell; Robert Winter; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; IT-investments; IT-investment evaluation; Business value assessments; Enterprise architecture; Technical evaluation of IT systems; Electric power industry; Industrial organisation; administration and economics; Industriell organisation; administration och ekonomi;

   Abstract : s the dependence of IS/IT has grown in modern organizations, IT investments have soared in the last couple of decades. Large amounts of money are spent with the hope that the investments will generate value for the business organizations using the systems. READ MORE

4. 2. Decentralized Application Security

   Author : Per Hallgren; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Decentralization; Homomorphic Encryption; Location-Based Services; Privacy;

   Abstract : On the internet today, everything is centralized. For most people, a single commercial entity owns the power to disclose all their personal emails. Most commonly your emails are only disclosed to you and your correspondent, but the power to choose who sees these emails is in fact not yours. READ MORE

5. 3. Polymer-shelled Ultrasound Contrast Agents : Characterization and Application

   Author : Dmitry Grishenkov; Leif Kari; Lars-Åke Brodin; Michel Versluis; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ultrasound; contrast agents; microbubbles; polymer; perfusion; Acoustics; Akustik; Material physics with surface physics; Materialfysik med ytfysik; Cardiovascular medicine; Kardiovaskulär medicin; Cardiology; Kardiologi;

   Abstract : Ultrasound-based imaging technique is probably the most used approach for rapid investigationand monitoring of anatomical and physiological conditions of internal organs and tissues.Ultrasound-based techniques do not require the use of ionizing radiation making the tests anexceptionally safe and painless.

6. 4. Secondary chlorophyll a luminescence decay kinetics from green algae and higher plants : mechanisms and application

   Author : Lars-Göran Sundblad; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; luminescence; fluorescence; photosynthesis; far red; CO2 accumulation; S-states; QA; reverse coupling; qE; frost hardiness;

   Abstract : Barley protoplasts were shown to be a suitable experimental system for studies on the relative maximum during the decay of luminescence observed in most photosynthetic systems after excitation with far red light and in the presence of O2. The far red induced relative luminescencemaximum was shown to be a result of three coinciding events:*Randomization of the S-states of the water splitting system during illumination with far red light.

7. 5. Hierarchical Methods for Self-Monitoring Systems : Theory and Application

   Author : Pablo José Del Moral Pastor; Sławomir Nowaczyk; Sepideh Pashami; Niklas Lavesson; Högskolan i Halmstad; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Self-monitoring solutions first appeared to avoid catastrophic breakdowns in safety-critical mechanisms. The design behind these solutions relied heavily on the physical knowledge of the mechanism and its fault. They usually involved installing specialized sensors to monitor the state of the mechanism and statistical modeling of the recorded data. READ MORE
