Methodology development and evaluation of automotive LiDAR performance in rain
… sensors are affected when driving in rain due to soiling, which causes light attenuation by the droplets in the atmosphere and on the sensor lens cover. Therefore, autonomous vehicle developments require extensive field and lab testing on sensor perceptions in different environments and weather …

Scottish market crosses: the development of a risk assessment model.
… the causes and effects of stone decay and soiling upon Scottish market crosses, and to develop a risk assessment model for this monument type. Risk assessment methods are otherwise used in spheres of business and industry. This research is unique in exploring the possibility of applying …

An evaluation of locally available cleaning methods on a globigerina limestone surface
… least damage for the particular existing type of soiling. The reason for choosing a specific building is that each building has a unique solution due to the widely varying characteristics of the limestone and due to the different types of soiling that could be present on different buildings. The …

Thermal property of EDS film and its effect on the removal of dust particles as a function of surface temperature
… causes a loss of energy conversion efficiency by soiling solar collectors. Electrodynamic Screen (EDS) film when laminated over photovoltaic module, works as a self-cleaning technology designed for soiling loss mitigation of solar plants and it requires no water and consumes very low energy. …

Applications of Deep Learning, Machine Learning, and Remote Sensing to Improving Air Quality and Solar Energy Production
… (PM) on solar photovoltaics (PVs), known as soiling, can diminish solar energy production appreciably. As of 2018, the global cumulative PV capacity crossed 500 GW, of which at least 3–4% was estimated to be lost due to soiling, equivalent to ~4–6 billion USD revenue losses. In the context of …

Topographic characterization of polymer materials at different length scales and the mechanistic understanding of wetting phenomena
… wefts, were studied. To characterise the soiling behaviour, an ‘spot analysis method’ was suggested, allowing wetting dynamics studies of liquids on fabrics with anisotropic surface properties. This method is applicable also to surfaces with anisotropic roughness characteristics and to …

Hospital admission patterns of childhood respiratory illness in Cape Town and their association with air pollution and meteorological factors
… respiratory infections and oxides of nitrogen, soiling index, and temperature; (2) asthma and oxides of nitrogen (3) total admissions and soiling index, average temperature and minimum temperature (negative). The study concluded that despite generally low levels of air pollution in Cape Town, …

A study of the soil removal and redeposition properties of three commercial detergents from Kenya
… of fabrics, and various types and levels of soiling, while in developing countries, the choice is limited to a few varieties. Despite this, there are certain cleaning products such as OmoTM in Kenya, which are preferred by consumers because they are convinced that it performs better than the …

Visceral Creativity: Digestion, Earthly Melancholy, and Materiality in the Graphic Arts of Early Modern France and the German-Speaking Lands (c. 1530-1675)
… process was often considered as an act of ‘soiling’ oneself, both in the sense of the body and the phantasia. This thesis focuses on a period spanning c. 1530 to 1675, from Rabelais’ works to the facetious printer Jacques Lagniet. It mines a corpus of little-studied textual and visual …

TOWARD A BETTER CLEANING AND SELECTIVITY IN ELECTROANALYSIS: TIO2-BASED SENSORS AND ENANTIOSELECTIVE MATERIALS
… presence of dopamine, a molecule known for its soiling problems. The titanium dioxide layer was deposited onto the microelectrode surface through a pseudo-calcination process and its behaviour was studied after the use of the sensor for the detection of dopamine. It has been seen that it is …

Spatiotemporal Performance Analysis to Identify Degradation Trends in a Utility-Scale PV Plant
… it was caused by the combination of wind-induced soiling and thermal stress. Following this, a visualisation framework was implemented to analyse the interannual spatial and temporal performance trends of the PV plant at string-pair and inverter levels. This analysis highlighted the regional and …

The Influence of Feed and Sunshine on the Vitamin D Content of Cow’s Milk
… very little, if any, green food, either as soiling crops or as pasture. From many standpoints such practices are, of course, necessary and desirable, but from the standpoint of the nutritional value of the milk produced there are those who question the desirability of such practices. On July …

Anorectal malformations - their impact on early phases in life
Abstract: Background : Anorecta l malformation s (ARM) occur in 4: 10000 newborn children with the gender distribut ion 1:1.5 females:males. The reconstruction of ARM, posterior sagiccal anorectal plasty (PSARP), was implemenred worldwide in the late 1980s and therefore the follow-ups are limited. …
