Cumulative Curves for Exploration of Demographic Data: a Case Study of Northwest England
نویسندگان
چکیده
The paper introduces the idea of generalising a cumulative frequency curve to show arbitrary cumulative counts. For example, in demographic studies generalised cumulative curves can represent the distribution of population or area. Generalised cumulative curves can be a valuable instrument for exploratory data analysis. The use of cumulative curves in an investigation of population statistics in Northwest England allowed us to discover interesting facts about relationships between the distribution of national minorities and the degree of deprivation. We detected that, while high concentration of national minorities occurs, in general, in underprivileged districts, there are some differences related to the origin of the minorities. The paper sets the applicability conditions for generalised cumulative curves and compares them with other graphical tools for exploratory data analysis.

Investigation of the Distribution of Cumulative Ductility Demand Parameter in Various Storeys of Buckling Restrained Braced Frames
Due to the fact that the buckling-restrained brace core yields subject to both tension and compression, it can adsorb energy and exhibit high ductility rendering it proper for tolerating earthquake loads. One of the important objectives of seismic standards is safeguarding the appropriate ductility for the structures because the structures, in case of being ductile, can dissipate a considerable...

In this study, we obtained two-dimensional tomography maps of the Rayleigh wave group velocity for the northwest part of the Iranian Plateau in order to investigate the structure of the crust and the uppermost mantle of NW Iran. To do this, the local earthquake data during the period 2006-2013, recorded by the 10 broadband stations of the Iranian seismic network (INSN) were used. After the prel...
متن کاملCRFA-CRBM: a hybrid technique for anomaly recognition in regional geochemical exploration; case study: Dehsalm area, east of Iran
Identification of geochemical anomalies is a significant step during regional geochemical exploration. In this matter, new techniques have been developed based on deep learning networks. These simple-structure-networks act like our brains on processing the data by simulating deep layers of thinking. In this paper, a hybrid compositional-deep learning technique was applied to identify the anomal...

Background: Iran detected its first COVID-19 case in February 2020 in Qom province, which rapidly spread to other cities in the country. Iran, as one of those countries with the highest number of infected people, has officially reported 1812 deaths from a total number of 23049 confirmed infected cases that we used in the analysis. Materials and Methods: Geographic distribution by the map of ca...

Motivated by the recent successful results of using GIS modeling in a variety of problems related to the geosciences, some knowledge-based methods were applied to a regional scale mapping of the mineral potential, special for Cu-Au mineralization in the Feyz-Abad area located in the NE of Iran. Mineral Prospectivity Mapping (MPM) is a multi-step process that ranks a promising target area for mo...
