  2. 1. Precision measurement instruments for machinery's mechanical compliance: design and operation : Measurement instruments for physics-based calibration of advanced manufacturing machinery

    Author : Nikolas Alexander Theissen; Andreas Archenti; Alexander Slocum; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Measurement instruments; Machine tools; Industrial robots; Production Engineering; Industriell produktion;

    Abstract :  Precision Measurement Instruments (PMIs) for machinery’s mechanical compliance are tools to quantify mechanical load as well as length for measurement ranges of 0.1 µm to 10 m at uncertainty levels of 0.1 µm to 100 µm while exerting mechanical loads. READ MORE

  4. 2. A new approach for considering the interference impact on digital radio systems from complex interference environments

    Author : Kia Wiklundh; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; minimum shift keying; class A; amplitude probability distribution; bandwidth conversion; Gaussian approximation; emission; non-Gaussian interference; performance estimation; man-made noise; measurement; emission requirements; micro-wave oven; MSK; coding gain; APD; interference;

    Abstract : Interference from electrical equipment can severely degrade aco-located digital radio receiver. To avoid such performance degradation, it isnecessary to have estimation methods to predict the influence of an interferenceenvironment on a radio receiver. READ MORE

  5. 3. CPU Resource Management and Noise Filtering for PID Control

    Author : Vanessa Romero Segovia; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; resource management; embedded systems; real-time systems; multimedia; multicore; measurement noise; filtering; trade-offs; robustness; performance; SDU; noise gain; PID control;

    Abstract : The first part of the thesis deals with adaptive CPU resource management for multicore platforms. The work was done as a part of the resource manager component of the adaptive resource management framework implemented in the European ACTORS project. The framework dynamically allocates CPU resources for the applications. READ MORE

  6. 4. Experimental and numerical study of the thermal and hydraulic effect of EMC screens in radio base stations : detailed and compact models

    Author : Raúl Antón Remírez; Björn Palm; Masud Behnia; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sub-rack; perforated plate; air cooling; 90 degrees turn; flow deistribution; CFD; measurement; Mechanical energy engineering; Mekanisk energiteknik;

    Abstract : Today’s telecommunication cabinets use Electro Magnetic Compliance (EMC) screens in order to reduce electromagnetic noise that can cause some miss functions in electronic equipment. Many radio base stations (RBSs) use a 90-degree building architecture: the flow inlet is perpendicular to the EMC screen, which creates a complex flow, with a 90-degree air turn, expansions, compressions, perforated plates and PCBs.

  7. 5. Evolving geriatric anthropometrics- an interplay with lifestyle changes, birth cohort effects, and survival implications. : Results from the general population study, “Good Aging in Skåne,” Sweden

    Author : Nivetha Natarajan Gavriilidou; Geriatrik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anthropometrics; BMI misclassification; measurement; error correction; prediction equation; surrogate; survival; lifestyle; birth cohort; Swedish elderly; assessment;

    Abstract : There is a rising proportion of aging population worldwide. The high vulnerability of older adults to morbidity and mortality introduces an enormous health and economic burden to themselves and the society. The established leading cause of death among older adults is due to chronic and vascular diseases. READ MORE
