A sensing platform for the in situ, real-time analysis of phosphate in natural waters has been realised using a combination of microfluidics, colorimetric reagent chemistries, low-cost LED-based optical detection and wireless communications. Prior to field deployment, the platform was tested over a period of 55 days in the laboratory during which a total of 2682 autonomous measurements were performed (854 each of sample, high standard and baseline, and 40 × 3 spiked solution measurements). The platform was subsequently field-deployed in a freshwater stream at Lough Rea, Co., Galway, Ireland, to track changes in phosphate over a five day period. During this deployment, 165 autonomous measurements (55 each of sample, high standard, and baseline) were performed and transmitted via general packet radio service (GPRS) to a web interface for remote access. Increases in phosphate levels at the sampling location coincident with rainfall events (min 1.45 µM to max 10.24 µM) were detected during the deployment. The response was found to be linear up to 50 µM PO43−, with a lower limit of detection (LOD) of 0.09 µM. Laboratory and field data suggest that despite the complexity of reagent-based analysers, they are reasonably reliable in remote operation, and offer the best opportunity to provide enhanced in situ chemical sensing capabilities. Modifications that could further improve the reliability and scalability of these platforms while simultaneously reducing the unit cost are discussed.

IntroductionNew non-vitamin K Target Specific Oral Anticoagulants (TSOACs) have a favourable risk-benefit profile and debatable cost effectiveness. Large numbers and data from multiple countries in a European study are required to investigate safety issue of TSOACs in subgroups, e.g. people with an intracranial haemorrhage. Objectives and ApproachWe developed an approach to rapidly replicate data and analyses to support cross-country distributed research within the UK/EU using Electronic Health Records (EHRs). This project was conceptualised and initialled by linking relevant datasets held in multiple data warehouses, in Scotland with the Scottish National Data Safe Haven, and in Wales through the Secure Anonymised Information Linkage (SAIL) databank. Analysts in Edinburgh and Swansea had remote access to each other’s datasets and worked collaboratively to harmonise variables and analysis scripts. . A common R code script has been produced to harmonise individual data as well as the outputs from the study. ResultsThe study screened data on 8M people to develop a cohort that included pseudonymised information of 4,153 individuals in Scotland and 2,676 individuals in Wales, 6,829 individuals in total. Standardised risk analyses were completed in both settings with ongoing work in combining the analyses. In Wales, 39.5% of the patients in the cohort had been admitted to hospitals due to serious vascular events or died caused by these events, after intracranial haemorrhage. Incident rates for male and female are 0.63 and 0.7 respectively. Within the cohort, 0.5% were prescribed with TSOACs and 3% with Warfarin (included as reference). The project is also in the process of including other European jurisdictions. Conclusion/ImplicationsThe adopted approach was the simplest, yet most efficient and cost-effective method to ensure consistency in analysis and coherence with currently available governance systems of both safe havens. It can also be considered as an initialisation of developing infrastructure to support research using EHRs across the UK and EU.

Modern applications for analysing 2D/3D data require complex visual output features which are often based on the multi-platform OpenGL® API for rendering vector graphics. Instead of providing classical workstations, the provision of powerful virtual machines (VMs) with GPU support in a scientific cloud with direct access to high performance storage is an efficient and cost effective solution. However, the automatic deployment, operation and remote access of OpenGL® API-capable VMs with professional visualization applications is a non-trivial task. In this chapter the authors demonstrate the concept of such a flexible cloud-like analysis infrastructure within the framework of the project ASTOR. The authors present an Analysis-as-a-Service (AaaS) approach based on VMware™-ESX for on demand allocation of VMs with dedicated GPU cores and up to 256 GByte RAM per machine.

The Government

The Marine Region of the Hong Kong Police Force is responsible for policing the waters and 262 islands that lie within the 1,651 square kilometers of the Hong Kong Special Administrative Region (HKSAR). In addition to routine policing, the Marine Region has responsibilities in other diverse areas like quarantine, immigration, conservancy, and also port and maritime regulations (Hong Kong Police Force, 2005). The Region is now managing a police fleet of over 140 vessels of various classes. A modern police vessel is a complex, technologically advanced, and highly automated machine. As such, the Marine Region Support Bureau (MRSB) insisted that it must be maintained at the highest possible levels of operational availability while its life cycle operating and maintenance costs should be kept at a minimum. To achieve this aim, this article addresses the need to effectively implement a marine maintenance information system. Traditionally, the defects and maintenance data of the fleet were collected and recorded by the crew in writing, and then the maintenance records were used as the basis for maintenance decisions by the MRSB and the Hong Kong Government Dockyard. With the paper-based recording procedure, the following problems often occur: • There are missing data due to unintentional negligence or uncertainty about the nature of the equipment failure or damage, • errors occurred during the coding of failure information, and • there is difficulty in deciding whether repair tasks performed were routine servicing or corrective maintenance. To minimize such problems, it was decided that the processes of crew logbook entry and failure coding procedures would be replaced by direct input to the desktops of MRSB and the Government Dockyard through portable communication devices such as personal digital assistants (PDAs) and laptops, which can easily be obtained at reasonable costs locally. Currently, virtual private networks (VPNs) provide one of the most cost-effective ways for users to access organization networks while in Hong Kong waters. They are also an effective way of joining together the main office with remote depots using the public Internet. Three types of VPNs are being used. 1. Intranet VPN: This VPN can securely connect the desktops of the MRSB and the HKSAR Government Dockyard over the intranet, with all data traffic being encrypted. 2. Extranet VPN: Besides the functions provided by the intranet VPN, this network provides access to the MIS to preferred maintenance contractors. Data are accessible only over secure encrypted connections, with all contractor users authenticated. 3. Remote-Access VPN: For this network, authorized users are able to access the MRSB and HKSAR Government Dockyard MIS anytime from anywhere. With the aid of wireless PDAs, this facilitates decision making on the spot and is limited to decision makers such as the police superintendent. A preliminary attempt at developing a Web-based maintenance management information system was carried out for a small fleet of patrol vessels (Wong & Chan, 2002), and due to the nonmodular structure, a major difficulty was found in the modification and extension of the system framework. Recent advances in VPN technology indicate that VPN WANs (wide area networks) are now faster, cheaper, and more reliable than traditional WAN technologies. For a successful implementation of the IMIS, an efficient framework is needed to achieve the automaton of diagnostic processes and the integration of inspection and maintenance information under a secure communication infrastructure. Prior to an elaboration on the design of the proposed model, a brief review of object-oriented technologies (OOTs) is shown in the following section.

This study focused on farmers’ attitudes to the effectiveness of ICTs in their farming and farmers’ challenges in accessing it. Extension workers of the respective Townships identified the 144 sample farmers, and the data was collected through interviews using questionnaires during 2019.  There were frequency means and a dichotomous scale used to analyze the ICT attitude pattern among farmers and a 5-point Likert scale with the options.  This study explored the personal factors of ICT accessed farmers who are significantly getting young and middle age, high school, and graduate-level education and a moderate working experience compared with ICTs non- access farmers. 110 out of 144 farmers frequently used and accessed ICTs such as Radio, FM radio, TV, Facebook, Phone, and Agricultural Journals to obtain the agricultural information, but 34 farmers could not access ICTs due to the high cost, other social factors, and low ICT exposure. Most of the farmers received agricultural information from related Departments and Organizations traditionally, such as training, meeting, demonstration, trials, and conferences. More than half of the farmers were positively consistent agricultural information with their needs, but the rest did not meet their needs. Most farmers believed highly positive to agricultural information. However, some farmers responded negatively to agricultural details because they seem commonly knowledgeable information. Farmers mentioned in this study that more than half of farmers positively showed that attitude on high true and true regarding agricultural information. Moreover, farmers encountered insufficient electricity, challenging ICT exposure, low trust, and social problems. And also, farmers commonly faced challenges as high cost for ICT usage, high price for ICTs tools, and poor ICT service.  Besides, farmers’ other challenges were poor connectivity, inadequate support for the mother service provider, failure to attend the training, complexity to operate, and badly wanted news. Finally, this study recommended that farmers use effective utilization of ICTs in their farming in Nay Pyi Taw area that has the potential to make the rural communities prosperous as it enables the dissemination of required information in user-friendly patterns, easy to access, cost-effective ways at the right time with relevant information and training to be a skill.

ABSTRACTObjectivesIn response to Data Custodian and Researcher's request to assist improving the timeliness and ease of data extractions, SA NT DataLink established the Custodian Controlled Data Repository (CCDR). Issues including conflicting work priorities and limited resources do prevent timely data extractions. SA NT DataLink, as a trusted third party enable Custodians to hold separate copies of their de-identified content data ready for timely release. The CCDR is opt-in for Custodians. Its key strength being the data remains under the control of participating Custodians, with Custodians updating and correcting their data. SA NT DataLink staff are work with Data Custodians to clean, standardise, update and prepare data in advance of anticipated approvals, including spatial enabled GIS variables. SA NT DataLink staff work under the direction of the Data Custodians, taking responsibility for preparing the data extractions required for the approved project. ApproachThe SA NT DataLink Custodian Controlled Data Repository (CCDR) takes advantage of the Secure Unified Research Environment (SURE), which is a secure remote access data laboratory operated by the Sax Institute in Sydney Australia. Using thin client and two-factor authentication, Data Custodians from South Australia and across Australia are able to securely store and maintain de-identified copies of their content data in SURE, ready for standardisation, quality review, and more timely release for approved use and data linkage projects. ResultsThe CCDR functional diagram provides an understanding of the data flow and processes that support more timely, easy and cost effective collation and provision of de-identified and privacy protected data. The Curated Gateway feature of SURE manages all the data coming into and being released from the Repository. Agreed regular updates of Data Custodian's data is able to be stored into their sub-directory, with access to the sub-directory managed by authentication and passwords. The SA NT DataLink Analysts is able to perform the role of data integrator for approved projects and use, also running privacy protecting algorithms and verification of the data being provided against the approvals. ConclusionThe CCDR securely stores the de-identified data ready for it to be integrated and released to Researchers. Use of secure remote access technologies allows Data Custodians to maintain control of their preloaded and pre-cleaned data in CCDR. In doing so this allows Custodians to authorise the use, from which SA NT DataLink staff dedicated to working only in the CCDR, integrate and release the data in a more timely manner.

Abstract Model-based soft sensors can enhance online monitoring in wastewater treatment processes. These soft sensor scripts are executed either locally on a programmable logic controller (PLC) or remotely on a system with data-access over the internet. This work presents a cost-effective, flexible, open source IoT solution for remote deployment of a soft sensing algorithm. The system uses low-priced hardware and open-source programming language to set up the communication and remote-access system. Advantages of the new IoT architecture are demonstrated through a case study for remote deployment of an Extended Kalman Filter (EKF) to estimate additional water quality parameters in a multistage moving bed biofilm reactor (MBBR) plant. The soft-sensor results are successfully validated against standardised laboratory measurements to prove their ability to provide real-time estimations.
