    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Samanah Seyedi-Shandiz; [2014]
    Keywords : schematic Diagram; geographical representation; schematic representation; GIS; ArcGIS Schematics; physical geography; ecosystem analysis; Earth and Environmental Sciences;

    Abstract : Today, one of the needs of the railway information systems is sharing the precise and exact data among varieties of stakeholders. In addition, efficient use of Geographical Information Systems (GIS) encourages the railways administrations to centralize their data and prepare an information model whose purpose is to reduce the demands associated with the transformation of the data.

  3. 22. Measuring muscle movements with reflective photosensors

    University essay from KTH/Skolan för teknik och hälsa (STH)

    Author : Ghattas Ghattas; aldin Jerjas; [2014]
    Keywords : optomyography; muscle movements; reflective photosensors; skin surface variation;

    Abstract : Optomyography is the term chosen to name a device containing several reflective photosensors placed in an armband. The device is constructed so that it can measure muscle movements in the arm through the detection of skin structure variation. READ MORE

  4. 23. A Comparison of EDMOS and Cascode Structures for PA Design in 65 nm CMOS Technology

    University essay from Elektroniska komponenter; Tekniska högskolan

    Author : Mahir Jabbar Rashid Al-Taie; [2013]

    Abstract : This thesis addresses the potential of implementing watt-level class-AB Power Amplifier (PA) for WLAN in 65 nm CMOS technology, at 2.4 GHz frequency. In total, five PAs have been compared, where the examined parameters were output power (Pout), linearity, power added efficiency (PAE), and area consumption. READ MORE

  5. 24. Heat storage in lead-acid accumulators on-board submarines.

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Hed Henrik; [2011]
    Keywords : heat storage lead-acid accumulators submarines; Technology and Engineering;

    Abstract : A Swedish submarine often operates in colder waters, resulting in a cold on-board climate and a low temperature in the batteries. The batteries reaches their maximum capacity when they are at a temperature of 30°C, which they rarely are during the winter months when the temperature often is lower than 7°C. READ MORE
