Seismic imaging of glaciomarine sediments of Antarctica: optimizing the acquistion parameters
No full text412-418This paper presents some of the significant points on the designing and acquisition parameters for multi-channel seismic reflection survey in the Antarctic waters with an emphasis of imaging Glaciomarine sediments. Due to their importance in unravelling the paleoclimatic clues, we stress on the practical aspects of seismic data acquisition focussed on targeting glaciomarine sediments on the Antarctic margin. We carried out extensive forward modelling exercise assuming sub-surface model parameters from the published literature pertaining to the Eastern Antarctic Margin (EAM). The reason for choosing this area is that the Prydz Bay sector of EAM has been known to have undergone huge glacial sediment accumulation in the past due to its contiguity with the Amery Ice Shelf. In this article we suggest the best suited acquisition parameters for collecting high quality multi-channel seismic data in order to image the Glaciomarine sediments in this region

Deep Learning-Based Femoral Cartilage Automatic Segmentation in Ultrasound Imaging for Guidance in Robotic Knee Arthroscopy
No full textIn final from 18 October 2019.Knee arthroscopy is a minimally invasive surgery used in the treatment of intra-articular knee pathology which may cause unintended damage to femoral cartilage. An ultrasound (US)-guided autonomous robotic platform for knee arthroscopy can be envisioned to minimise these risks and possibly to improve surgical outcomes. The first necessary tool for reliable guidance during robotic surgeries was an automatic segmentation algorithm to outline the regions at risk. In this work, we studied the feasibility of using a state-of-the-art deep neural network (UNet) to automatically segment femoral cartilage imaged with dynamic volumetric US (at the refresh rate of 1 Hz), under simulated surgical conditions. Six volunteers were scanned which resulted in the extraction of 18278 2-D US images from 35 dynamic 3-D US scans, and these were manually labelled. The UNet was evaluated using a five-fold cross-validation with an average of 15531 training and 3124 testing labelled images per fold. An intra-observer study was performed to assess intra-observer variability due to inherent US physical properties. To account for this variability, a novel metric concept named Dice coefficient with boundary uncertainty (DSCUB) was proposed and used to test the algorithm. The algorithm performed comparably to an experienced orthopaedic surgeon, with DSCUB of 0.87. The proposed UNet has the potential to localise femoral cartilage in robotic knee arthroscopy with clinical accuracy.M. Antico, F. Sasazawa, M. Dunnhofer, S.M. Camps, A.T. Jaiprakash, A.K. Pandey, R.

Improving freshwater monitoring frameworks for data and research management: report of user engagement initiative January 2018
No full textThe India-UK Water Centre (IUKWC) promotes cooperation and collaboration between the complementary priorities of NERC-MoES water security research.
This report presents an overview of the joint India-UK scientific User Engagement Initiative held in Kochi from 23rd– 25th January, 2018. The event was convened by the India-UK Water Centre cocoordinators Dr A.K. Sahai (Indian Institute of Tropical Meteorology, Pune, India) and Dr Harry Dixon (Centre for Ecology & Hydrology, Wallingford, UK). The initiative was organised by IUKWC Secretariat in collaboration with the Plymouth Marine Laboratory, UK and Nansen Environmental Research Centre, Kochi. The event aimed to engage regional-level water policy and management bodies in discussions about how the latest India-UK scientific outputs could be used to help improve freshwater monitoring frameworks and data for research and management in the southern Indian region. The event was specifically focused towards addressing four key themes:
Water Quality - Monitoring Pollution & Treatment; Monitoring Aquatic Ecosystems & Biodiversity; Irrigation - Monitoring Availability and Consumption; and Water Provision : Monitoring Supply & Consumption.
The event was multi-sectoral and multi-stakeholder in nature. Representatives from organizations responsible for the development of water policy and the management of freshwater issues in Kerala, Karnataka, Tamil Nadu, Maharashtra, Andhra Pradesh and Orissa attended. Amongst others, this included the Kerala Biodiversity Board, Kerala Water Resources Department, Karnataka State Biodiversity Board, Karnataka Water Resources Department, Maharashtra Pollution Control Board, Tamil Nadu Water Supply Board, and Orissa Pollution Control Board.
Discussion focused on the theme of Improving Freshwater Monitoring Frameworks and Data for Research and Management. Scientists from UK and Indian institutions presented the state-of-the-art in joint India-UK water security research, in the areas of water supply and management, water quality, biodiversity and irrigation. Indian Institutions including the National Institute of Hydrology, Roorkee, National Institute of Oceanography, Kochi, Central Marine and Fisheries Research Institute, Kochi, Indian Institute of Technology, Roorkee, Ashoka Trust for Research in Ecology and Environment, Cochin University of Science & Technology, Indian Institute of Science, Bangalore, National Water Academy, amongst others, participated actively in the initiative. UK participants included experts from the Centre for Ecology & Hydrology, British Geological Survey, University of Stirling and University of Portsmouth.
This report outlines the structure, participation, presentation and discussion sessions undertaken during the course of the event. The report is intended for the workshop participants, India-UK Water Centre members and stakeholders
Flow over partially liquid filled cavity
No full textExperiments have been carried out to investigate the effect of liquid cavity filling on the behavior of the gas flow over a flat plate cavity. PIV measurements in the gas phase reveal that cavity filling can affect vortex shedding in the cavity mouth. Shear layer vortices can break-up into smaller vortices, thereby losing their periodic interaction with the aft wall and, hence, their sound producing potential. Expected is that this is one of the mechanisms causing sound mitigation in corrugated pipes with liquid addition, observed in literature
ADOPTION OF A CHILD WITHOUT CONSENT OF ITS PARENT WITH A INTELLECTUAL DISABILITY : CASE OF A.K. AND L. v. CROATIA
No full textThis paper discusses the matter of parents prior right to provide his/her child with care in situations in which a child’s parent is a person with intellectual disabilities. The author analyzes the case of A.K. and L. v. Croatia in which European Court of Human Rights concluded that it come to violation of the right to family life of A.K, a mother with an intellectual disability and her son L., who was adopted without the mother’s consent. The paper presents a critical review of Croatian family law in a matter of a parent’s consent for an adoption when the parent is a person with intellectual disabilities. By connecting contemporary standpoints of the European Court of Human Rights and the latest scientific knowledge about the ability of persons with intellectual disabilities to take care of their child, the author discusses a possible conflict between the principle of child’s best interest and the priority right of a parent to take care of his/her child. Also, the author warns about the danger of a parent with intellectual disabilities being deprived of his/her parental rights and completely excluded from the process of adoption even in situations when the parent could, with adequate professional help and support, maintain a family relationship with the child. From that perspective the author also discusses the latest reforms of the family law concerning protection of parental rights of persons deprived of their capacity for work
