ROV operators often encounter challenges with orientation awareness while operating underwater, primarily due to relying solely on 2D camera feeds to manually control the ROV robot arm. This limitation in underwater visibility and orientation awareness, as observed among Malaysian ROV operators, can compromise the accuracy of arm placement, and pose a risk of tool damage if not handle with care. To address this, a 3D orientation monitoring system for ROVs has been developed, leveraging measurement sensors with nine degrees of freedom (DOF).

However, restrictions on site selection and severe weather conditions have hindered the establishment and operation of photovoltaic (PV) power stations. Previous studies have not considered meteorological factors when evaluating site suitability, leading to research gaps in identifying suitable areas and establishing indicator systems.
View Article and Find Full Text PDFDesertification constitutes a grave threat to the environmental and socio-economic stability of desertification frontline states in Northern Nigeria. From 2003 to 2020, this research comprehensively analyzes desertification vulnerability, integrating parameters such as NDVI, LST, TVDI, MSAVI, and Albedo. Key factors contributing to land degradation are identified, along with the spatial patterns and trends of desertification over the two-decade period.

- - Land-use change significantly contributes to biodiversity loss in Africa, yet there has been limited research on future projections due to uncertainties; this study aims to fill that gap by analyzing various land-use scenarios from 2021 to 2100.
- - The research uses 2020 observational land-use data to evaluate future changes across seven Shared Socioeconomic Pathways (SSP) scenarios, finding strong correlations (0.89) between current and projected land uses.
- - Projected outcomes indicate a decrease in barren and forest land, while cropland, grassland, and urban areas will likely expand significantly, raising concerns about biodiversity loss and ecosystem health in the region.
Objective: To estimate the prevalence of obstructed labour, associated risk factors and outcomes across a network of referral hospitals in Nigeria.
Design: Retrospective observational study.
Setting: A total of 54 referral-level hospitals across the six geopolitical regions of Nigeria.
