PROGRESS IN LABORATORY RESEARCH FOR FUNDAMENTAL PHYSICS SPACE MISSIONS USING OPTICAL DEVICES

ABSTRACT In this paper, we present the progress in our laboratory studies for fundamental physics space missions using optical devices. Specifically, we report on our progress in long fibre-linked heterodyne interferometry, tunable fibre directional coupler, fibre delay-line and picometer real-time motion control

Towards clinically viable neuromuscular control of bone-anchored prosthetic arms with sensory feedback

Promising developments are currently ongoing worldwide in the field of neuroprosthetics and artificial limb control. It is now possible to chronically connect a robotic limb to bone, nerves, and muscles of a human being, and to use the signals sourced from these connections to enable movements of the artificial limb. It is also possible to surgically redirect a nerve, deprived from its original target muscle due to amputation, to a new target in order to restore the original motor functionality. Intelligent signal processing algorithms can now utilize the bioelectric signals gathered from remaining muscles on the stump to decode the motor intention of the amputee, providing an intuitive control interface. Unfortunately, clinical implementations still lag behind the advancements made in research, and the conventional solutions for amputees have remained largely unchanged for decades. More efforts are needed from researchers to close the gap between scientific developments and clinical practices.This thesis ultimately focuses on the intuitive control of a prosthetic upper limb. In the first part of this doctoral project, an embedded system capable of prosthetic control via the processing of bioelectric signals and pattern recognition algorithms was developed. The design included a neurostimulator to provide direct neural feedback modulated by sensory information from artificial sensors. The system was designed towards clinical implementation and its functionality was proven by its use by amputee subjects in daily life. This system was then used during the second part of the doctoral project as a research platform to monitor prosthesis usage and training, machine learning based control algorithms, and neural stimulation paradigms for tactile sensory feedback. Within this work, a novel method for interfacing a multi-grip prosthetic hand to facilitate posture selection via pattern recognition was proposed. Moreover, the need for tactile sensory feedback was investigated in order to restore natural grasping behavior in amputees. Notably, the benefit for motor coordination of somatotopic tactile feedback achieved via direct neural stimulation was demonstrated. The findings and the technology developed during this project open to the clinical use of a new class of prosthetic arms that are directly connected to the neuromusculoskeletal system, intuitively controlled and capable of tactile sensory feedback

Wampar–English Dictionary with an English–Wampar finder list

This ethnographic dictionary is the result of Hans Fischer's long-term fieldwork among the Wampar, who occupy the middle Markham Valley in Morobe Province, Papua New Guinea (PNG). Their language, Dzob Wampar, belongs to the Markham family of the Austronesian languages. Today most Wampar speak not only Wampar but also PNG’s lingua franca, Tok Pisin. Six decades of Wampar research has documented the extent and speed of change in the region. Today, mining, migration and the commodification of land are accelerating the pace of change in Wampar communities, resulting in great individual differences in knowledge of the vernacular. This dictionary covers largely forgotten Wampar expressions as well as loanwords from German and Jabêm that have become part of everyday language. Most entries contain example sentences from original Wampar texts. The dictionary is complemented by an overview of ethnographic research among Wampar, a sketch of Wampar grammar, a bibliography and an English-to-Wampar finder list

Resources of tunas and related species and their fisheries in the Indian Ocean

With the new ocean regime coming into being, many of the countries including India have declared an EEZ (Exclusive Economic Zone) which extends national jurisdiction to 200 miles from the coast. This has created a greater awareness of our responsibility to wards the judicious exploitation of the living and non living resources coming under the extended jurisdiction. The problems of survey, assessment, utilization and management of the resources thus assumes priority. At the same time, the management of living resources, particularly the fishery resources receive both national and international importance. This is all the more so, as the exploitation of living resources has hitherto been confined to a narrow belt of the neritic waters. In the marine fisheries sector, with a decade of stagnation in world fish production, the declaration of the EEZ has given high hopes to some nations of substantially aug menting their fish production. To countries which had well established distant waterfishing operations covering the EEZ of other countries, the continuation of such operations poses serious problems. The new ocean regime undoubtedly offers some of the developing coun tries an opportunity for developing and expanding their capabilities of harvesting fish from their EEZ through their own effort or through collaborative ventures
