  1. 11. Thermal energy recovery of low grade waste heat in hydrogenation process

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Sofia Hedström; [2014]
    Keywords : Low-grade waste heat; Waste heat recovery; Organic Rankine Cycle; Absorption Refrigeration; Aspen Plus; Steady-state simulations; Modeling and design;

    Abstract : The waste heat recovery technologies have become very relevant since many industrial plants continuously reject large amounts of thermal energy during normal operation which contributes to the increase of the production costs and also impacts the environment. The simulation programs used in industrial engineering enable development and optimization of the operational processes in a cost-effective way. READ MORE

  2. 12. Extraction of radio frequency quality metric from digital video broadcast streams by cable using software defined radio

    University essay from Kommunikationssystem; Tekniska högskolan

    Author : Viktor Eriksson; [2013]
    Keywords : QAM; DVB-C; MER; BER; Gardner; Phase locked loop; Mueller Muller; RRC-filter; Carrier recovery; Timing Recovery; Matched filtering;

    Abstract : The purpose of this master thesis was to investigate how effiecient the extractionof radiofrequency quality metrics from digital video broadcast (DVB) streamscan become using software defined radio. Software defined radio (SDR) is a fairlynew technology that offers you the possibility of very flexible receivers and transmitters where it is possible to upgrade the modulation and demodulation overtime.

  3. 13. Live Demonstration of Mismatch Compensation for Time-Interleaved ADCs

    University essay from Elektroniksystem; Tekniska högskolan

    Author : Johan Nilsson; Mikael Rothin; [2012]
    Keywords : interleaving; analog-to-digital converter; digital communication; FPGA; analog video; carrier recovery; synchronization; RF modulation; SDR14;

    Abstract : The purpose of this thesis is to demonstrate the effects of mismatch errors that occur in time-interleaved analog-to-digital converters (TI-ADC) and how these are compensated for by proprietary methods from Signal Processing Devices Sweden AB. This will be demonstrated by two different implementations, both based on the combined digitizer/generator SDR14. READ MORE

  4. 14. An Investigation of the Nano-Organization of Glucose Transporters, Glut1 and Glut3, in the Mammalian Plasma Membrane

    University essay from Institutionen för vård och natur

    Author : Dommaraju Sireesha; [2008]
    Keywords : Sireesha; Dommaraju; Gluts; Sweden; Denmark; skovde; Odense; skovde University; SDU university;

    Abstract : Glucose is a monosaccharide and fuel for body, it cannot pass through membrane by simple diffusion so, integral transmembrane proteins named glucose transporters (Gluts) are involved in the regulation of the movement of glucose between the extracellular and intracellular spaces within the body. GLUT1 and GLUT3 have previously been shown by cold detergent extraction methods to reside in distinct plasma membrane domains in non-polarized mammalian cells, with GLUT1, but not GLUT3, residing  in detergent-resistant membrane (DRM) domains.

  5. 15. Environmental Systems Analysis of Waste Management : Prospects of Hydrogen Production from Waste for use in FCVs

    University essay from KTH/Industriell ekologi

    Author : Getachew Assefa; [2000]
    Keywords : Systems analysis; Life cycle analysis; Substance flow analysis; Waste management; Environmental impact; Steam reforming; Thermal gasification; Fuel cell vehicles; Hydrogen;

    Abstract : ORWARE, an evolving systems analysis based computer model is used to assess the performance of different waste management options from a life cycle perspective. The present version of the model consists of different submodels for transport, treatment, and disposal of different types of liquid and solid wastes and recycling of materials. READ MORE
