  1. 1. Nowcasting U.S. inflation using mixed frequency real-time data

    University essay from Lunds universitet/Matematisk statistik

    Author : Gustaf Lundgren; Nils Wicktor; [2023]
    Keywords : Inflation; Machine Learning; Nowcasting; MIDAS; Almon distributed lag models; Real-Time data; Random Forest; XGBoost; Mathematics and Statistics;

    Abstract : Different models were developed with the aim of nowcasting inflation at a daily basis with high frequency variables, while using real-time data to avoid look ahead bias. Both popular machine learning models such as Random Forest and XGBoost, and more traditional models such as UMIDAS and Almon distributed lag models were used to make the nowcasts. READ MORE

    Keywords : ;

    Abstract : To create the possibilities needed for more precise simulations and calculations regarding manufacturing changes in the equipment and new technology has to be implemented. This work investigates possible solutions for the gathering of information in manufacturing companies. READ MORE

  4. 3. Investigation of Modularization of Measurement Programs for CMMs

    University essay from KTH/Industriell produktion

    Author : Onur Ahmet Teke; [2013]
    Keywords : Metrology; CMM; Modularization; Measurement Programs; Metrologi; CMM; modularisering; mätprogram;

    Abstract : Coordinate measurement machines (CMMs) are used to control whether workpieces meet customers’ need or not. Creating measurement programs for CMMs takes long time and companies try to find a way to decrease the time for preparation processes. READ MORE

  5. 4. Devaluing the mitqal : Inherent Trading Fees in the Metrics of Birka

    University essay from Arkeologiska forskningslaboratoriet; Institutionen för arkeologi och antikens kultur

    Author : Joakim Schultzén; [2009]
    Keywords : archaeological science; metrology; viking age; Birka; Sigtuna; 3D scanner; weights; laborativ arkeologi; metrologi; vikingatid; Birka; Sigtuna; 3D skanner; viktlod;

    Abstract : Abstract: Previous research on the Viking Age trade centre of Birka has suggested the parallel use of two harmonising standard weight units, differing in mass by five percent. As an explanation to this phenomenon, this paper puts forward a hypothesis of a trading fee, embedded in the weights. READ MORE

  6. 5. Precision Amplifier for Applications in Electrical Metrology

    University essay from Elektroniksystem; Institutionen för systemteknik

    Author : Stefan Johanssson; [2009]
    Keywords : Electrical; Metrology; Precision; Buffer; Amplifier; CMRR;

    Abstract : This master's thesis addresses two main problems. The first is how to suppress a common mode voltage that appears for current shunts, and the second how to let a voltage divider work under an unloaded condition to prevent loading errors and thereby a decreased measurement accuracy.
