A synthetic segmentation dataset generator using a 3D modeling framework and raycaster: a mining industry application.

Many industries utilize deep learning methods to increase efficiency and reduce costs. One of these methods, image segmentation, is used for object detection and recognition in localization and mapping. Segmentation models are trained using labeled datasets; however, manually creating datasets for every application, including deep-level mining, is time-consuming and typically expensive.

Global Perspectives on Children's Digital Opportunities: An Emerging Research and Policy Agenda.

Diverse international perspectives show that children can benefit greatly from digital opportunities. Despite widespread optimism about the potential of digital technologies, especially for information and education, the research reveals an insufficient evidence base to guide policy and practice across all continents of the world, especially in middle- and low-income countries. Beyond revealing pressing and sizeable gaps in knowledge, this cross-national review also reveals the importance of understanding local values and practices regarding the use of technologies.

Accurate Vehicle Location System Using RFID, an Internet of Things Approach.

Modern infrastructure, such as dense urban areas and underground tunnels, can effectively block all GPS signals, which implies that effective position triangulation will not be achieved. The main problem that is addressed in this project is the design and implementation of an accurate vehicle location system using radio-frequency identification (RFID) technology in combination with GPS and the Global system for Mobile communication (GSM) technology, in order to provide a solution to the limitation discussed above. In essence, autonomous vehicle tracking will be facilitated with the use of RFID technology where GPS signals are non-existent.

Unregulated usage of labour-inducing medication in a region of Pakistan with poor drug regulatory control: characteristics and risk patterns.

Background: In developing countries such as Pakistan, poor training of mid-level cadres of health providers, combined with unregulated availability of labour-inducing medication can carry considerable risk for mother and child during labour. Here, we describe the exposure to labour-inducing medication and its possible risks in a vulnerable population in a conflict-affected region of Pakistan.

Methods: A retrospective cohort study using programme data, compared the outcomes of obstetric risk groups of women treated with unregulated oxytocin, with those of women with regulated treatment.

Determining the waist circumference cut off which best predicts the metabolic syndrome components in urban Africans: the SABPA study.

Various studies have shown that the relationship between waist circumference (WC) and abdominal obesity is age, gender as well as ethnicity-dependent. WC criteria for Sub Saharan Africans have not been defined by the International Diabetes Federation (IDF). The aim was to determine which WC cut off best predicted Metabolic Syndrome (MetS) in a group of urban African teachers (80 males and 93 females).

The prevalence of extreme Middle Eastern ideologies around the world.

The Belief Diversity Scale (BDS) was administered to Australian, Canadian, Egyptian, and South African participants of different religious backgrounds. The BDS is a 33-item, six subscale instrument that is designed to quantitatively measure Middle Eastern extremist ideologies on risk areas that are reported in the literature. Results demonstrated the reliability and validity of the BDS, thus suggesting that the BDS could be used as an objective tool to measure Middle Eastern extremist ideologies.
