An Account of the Loss of the Country Ship Forbes and Frazer Sinclair, Her Late Commander

This paper reports on the life of the English Country trader Captain Frazer Sinclair leading up to and following the loss of the Forbes in the Karimata Strait in 1806. It examines the adventure and tenuous times of trading around the Indonesian archipelago after the fall of the VOC and subsequent transfer to the British. Included are the details of Captain Sinclair\u27s trading history, multiple prizes as a privateer, and shipwrecks

A Deep Primal-Dual Network for Guided Depth Super-Resolution

In this paper we present a novel method to increase the spatial resolution of depth images. We combine a deep fully convolutional network with a non-local variational method in a deep primal-dual network. The joint network computes a noise-free, high-resolution estimate from a noisy, low-resolution input depth map. Additionally, a high-resolution intensity image is used to guide the reconstruction in the network. By unrolling the optimization steps of a first-order primal-dual algorithm and formulating it as a network, we can train our joint method end-to-end. This not only enables us to learn the weights of the fully convolutional network, but also to optimize all parameters of the variational method and its optimization procedure. The training of such a deep network requires a large dataset for supervision. Therefore, we generate high-quality depth maps and corresponding color images with a physically based renderer. In an exhaustive evaluation we show that our method outperforms the state-of-the-art on multiple benchmarks.Comment: BMVC 201

Primary task event-related potentials related to different aspects of information processing

The results of two studies which investigated the relationships between cognitive processing and components of transient event-related potentials (ERPs) are presented in a task in which mental workload was manipulated. The task involved the monitoring of an array of discrete readouts for values that went out of bounds, and was somewhat analogous to tasks performed in cockpits. The ERPs elicited by the changing readouts varied with the number of readouts being monitored, the number of monitored readouts that were close to going out of bounds, and whether or not the change took a monitored readout out of bounds. Moreover, different regions of the waveform differentially reflected these effects. The results confirm the sensitivity of scalp-recorded ERPs to the cognitive processes affected by mental workload and suggest the possibility of extracting useful ERP indices of primary task performance in a wide range of man-machine settings

Brain-wave measures of workload in advanced cockpits: The transition of technology from laboratory to cockpit simulator, phase 2

The present Phase 2 small business innovation research study was designed to address issues related to scalp-recorded event-related potential (ERP) indices of mental workload and to transition this technology from the laboratory to cockpit simulator environments for use as a systems engineering tool. The project involved five main tasks: (1) Two laboratory studies confirmed the generality of the ERP indices of workload obtained in the Phase 1 study and revealed two additional ERP components related to workload. (2) A task analysis' of flight scenarios and pilot tasks in the Advanced Concepts Flight Simulator (ACFS) defined cockpit events (i.e., displays, messages, alarms) that would be expected to elicit ERPs related to workload. (3) Software was developed to support ERP data analysis. An existing ARD-proprietary package of ERP data analysis routines was upgraded, new graphics routines were developed to enhance interactive data analysis, and routines were developed to compare alternative single-trial analysis techniques using simulated ERP data. (4) Working in conjunction with NASA Langley research scientists and simulator engineers, preparations were made for an ACFS validation study of ERP measures of workload. (5) A design specification was developed for a general purpose, computerized, workload assessment system that can function in simulators such as the ACFS

Health promotion indicators: current status, issues and problems

This article describes the background to the current status of health promotion indicator research and defines the major issues and problems involved. It then discusses both of these areas in detail. Problems in health promotion indicators fall under three major headings: methodologies, concepts and theories, and purpose and applications. Two other kinds of problems are discovered under these headings. Problems of methodology include djfficulties in measurement and data analysis. The issues in concepts and theories of indicators include defining the field and defining the theory, while issues in purposes and applications involve the use of indicators in the fields of research and policy. The authors conclude that the emerging paradigm of health promotion has a wider perspective than the paradigm of disease prevention, medical care and medical treatmen

Towards health promotion indicators

This article examines the state of the art in health promotion indicator development over the past few years and presents five conclusions from this review, The authors put forward proposals for the development of health promotion indicators based on the question, "What research in health promotion will lead to appropriate indicators?”. The authors illustrate some areas of concern both for researchers and policymakers and suggest a number of indicators, appropriate to each of these groups, for important dimensions of health, health-related processes and health resources. The dialogue between health researchers and health decision-makers is growing and links are being made; it is important to continue this proces
