2. 1. Modelling and Interference Analysis of AC-DC Converters for Immunity to Voltage Disturbances up to 150 kHz

   Author : Selcuk Sakar; Sarah Rönnberg; Math Bollen; Sjef Cobben; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AC-DC power converters; electromagnetic compatibility EMC ; high frequency disturbances; supraharmonics; switching converters; interharmonics; conducted disturbances; Electric Power Engineering; Elkraftteknik;

   Abstract : The function of electrical and electronic equipment is challenged by the high frequency emission originated from the more use of switching-based power electronic equipment and Power line communication (PLC) signaling. Investigations have shown that interferences occur in the frequency range between 2 kHz and 150 kHz, e.g. READ MORE

   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Uganda; Building industry; Labour Productivity;

   Abstract : Research has been pointing out that productivity in the building industry is stagnant and in some cases declining. Poor productivity of craftsmen is one of the causes of cost and time overruns on building projects. READ MORE

5. 3. Optimizing computed tomography : quality assurance, radiation dose and contrast media

   Author : Patrik Nowik; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Computed tomography (CT) is an important modality in radiology; it enables imaging of the inside of patients without superimposed anatomy. The radiation dose and quality of a CT image are highly dependent on the CT scanner, the scan settings and, if applicable, the timing and dosage of the intravenous contrast media (CM). READ MORE

6. 4. Data-driven lead-acid battery lifetime prognostics

   Abstract : To efficiently transport goods by heavy-duty trucks, it is important that vehicles have a high degree of availability and in particular avoid becoming standing by the road unable to continue the transport mission. An unplanned stop by the road does not only cost due to the delay in delivery, but can also lead to a damaged cargo. READ MORE

   Abstract : Since the ending of the Cold War, the defence sector, particularly the areas of military logistics and defence acquisition, has been undergoing a comprehensive transformation. There are several factors that explain this transformation: changes in defence and security policies for nations and organisations; reductions in defence expenditure; participation in Peace Support Operations; Lessons Learned from these operations, especially in the area of logistics; revolutionary development in the area of Information and Communication Technology; emergence of novel Commercial Best Practises in the areas of business and business logistics; and changes in the legislation regarding the conduct of public procurement in Europe.
