Multidimensional apportionment through discrepancy theory
Decidir cómo asignar los escaños de un órgano representativo es uno de los problemas más fundamentales en la organización política de las sociedades, y ha sido ampliamente estudiado desde hace ya dos siglos. La idea de proporcionalidad es la esencia de la mayoría de las formas de abordar este …

Quantitative Apportionment of Urban Aerosol Mass by Factor Analysis
A receptor method for quantitatively resolving the sources of airborne particulate matter was developed. This procedure, called target transformation factor analysis (TTFA), requires no prior knowledge about the nature of the system under study. TTFA can determine the number of sources that are …

Bayesian and Positive Matrix Factorization approaches to pollution source apportionment
… Matrix Factorization (PMF) in pollution source apportionment (PSA) is examined and illustrated. A study of its settings is conducted in order to optimize them in the context of PSA. The use of a priori information in PMF is examined, in the form of target factor profiles and pulling profile …

Reliability allocation and apportionment: addressing redundancy and life-cycle cost
… reliability analysis techniques, allocation and apportionment, have the potential to influence a system's design (a distinction is made here between allocation and apportionment). Algorithms that account for the ever increasing design complexities are constructed here for both. As designs of …

Fine particulate matter source apportionment of the brown haze in Cape Town
"Brown Haze" is a term used to describe a brown-coloured smog found predominantly in the wintertime in the Cape Town region. It occurs. mostly from April to September due to strong) temperature inversions and windless conditions that can occur during these months, which lead to the build-up of …

EXPLOITING ADVANCED ATMOSPHERIC AEROSOL CHARACTERISATION TO DEVELOP CUTTING-EDGE APPROACHES FOR SOURCE APPORTIONMENT
… atmospheric aerosol emission sources (source apportionment). In this way, policymakers can develop effective control strategies to mitigate atmospheric aerosol adverse impacts. In recent years, in parallel to more traditional filter-based aerosol characterisation, advanced instrumentation has …

Examination of the application and limitations of structural mode extraction via force apportionment
This paper will discuss the use of force apportionment to isolate modes being excited by the sine-dwell technique. The effectiveness of the apportionment technique can be determined by examining the structural response as measured by laser vibrometry. First, the structure is investigated using …

Value-Added Tax apportionment methodology applied in the higher sector of South Africa : Is the apportionment method currently applied in the higher education sector effective and appropriate in a South African context?
This dissertation focusses on the value-added tax apportionment methodology applied in the higher education sector of South Africa. The current apportionment method applied by universities is the varied input-based method. The research question that is posed, is whether the varied input-based …

SET-UP OF INNOVATIVE EXPERIMENTAL METODOLOGIES FOR THE ATMOSPHERIC AEROSOL CHARACTERISATION AND SOURCE APPORTIONMENT
… for the atmospheric aerosol characterisation and apportionment. Many issues are still open in aerosol science. Among them, the identification and quantification of PM sources and the separation between natural and anthropogenic contributions were explored in this work. To improve the …

Weed-soybean canopy apportionment as an estimation of soybean (Glycine max) development and yield loss
Field studies were conducted from 1986 through 1988 to evaluate developmental characteristics of soybean plants growing within 100 cm of a weed and to evaluate the usefulness of weed measurements in predicting the yield losses of soybeans growing next to jimsonweed (Datura stramonium) and common …

Characterization, seasonality and source apportionment of fine particulate organic matter at urban an d rural sites
… markers for secondary formation using source apportionment. This hypothesis was explored for an urban and a rural site in Texas as part of the second sampling campaign, the Texas Air Quality (TexAQS) II study. In the TexAQS II study, fine PM sources were first characterized more broadly, …

Pedogenic carbonates in loess formation rates, formation conditions and source apportionment assessed by isotopes and molecular proxies
Interest in secondary (pedogenic) carbonates as an archive for paleoclimatic reconstructions in arid and semiarid regions has increased during recent decades. Their carbon (C) isotope composition represents the conditions prevailing during their formation because they are formed by precipitation of …

Measurement, Characterization, and Source Apportionment of the Major Chemical Components of Fine Particulate Material, Including Semi-Volatile Species
… sampler data in the application of source apportionment was elucidated. Local aerosols are often impacted by short-term pollution episodes that cannot be temporally resolved using integrated samplers. One-h averaged data applied to source apportionment models was shown to increase the power …
