Kinematična metoda PPP (Precise Point Positioning) določitve položaja v GNSS
, 2017 V diplomski nalogi je obravnavana kinematična metoda PPP (Precise Point Positioning). Predstavljeni so osnovni teoretični koncepti in prednosti ter slabosti metode. Predstavljena je programska oprema, ki omogoča obdelavo opazovanj z metodo PPP. Za namen raziskave smo izvedli statična in kinematična opazovanja GPS in GLONASS.

Oxford Bulletin of Economics and Statistics, EarlyView.ABSTRACT This paper analyses the long‐term effects of preschool education in France. We focus on the effect of preschool duration on educational attainment and labour market earnings in adulthood. Building on an old tradition of free and universal pre‐primary education, France implemented in the late 1960s a large‐scale expansion of preschooling ...

Metoda Precise Point Positioning (PPP) določitve položaja v GNSS
In this graduation thesis we studied the Precise Point Positioning (PPP) method. The theoretical foundations are presented, including the effects and corrections that need to be considered. We carried out a reliability analysis of the method using the free Canadian online service CSRS-PPP. We used fullday observations from three permanent GNSS stations

Imputing Poverty Indicators Without Consumption Data: An Exploratory Analysis
Oxford Bulletin of Economics and Statistics, EarlyView.ABSTRACT Accurate poverty measurement relies on household consumption data, but such data are often inadequate, outdated, or display inconsistencies over time in poorer countries. To address these data challenges, we employ survey‐to‐survey imputation to produce estimates for several poverty indicators including headcount poverty, extreme poverty ...

Orthodontics &Craniofacial Research, EarlyView.ABSTRACT Background Root torque control is essential for guiding the proper movement of anterior teeth, primarily to prevent periodontal complications. This movement, in clear aligner therapy (CAT), requires precise force application to minimize unintended displacements.
