Visualizing Massive Pristine LIDAR Amplitude Responses

Airborne light detection and ranging (LIDAR)- based bathymetry is a highly specialized field within the widely known and used geoscientific surveying technology based on green spectrum lasers. Green light can penetrate shallow water bodies such that river and lake beds can be surveyed. The result of such observations are point clouds, from which geometries are extracted, such as digital elevation maps for lake, river or sea floors. The quality of those maps is crucially dependent on the amount of reliable information that can be extracted from the noisy LIDAR signals. The primary LIDAR data consists of amplitude response curves for each emitted laser signal. A direct visualization of these “raw”, pristine data is crucial to verify, assess and optimize subsequent data processing and reduction methods. In this article we present a method for scientific visualization of these amplitude response curves en mass, i.e. for millions and tens of millions thereof simultaneously. As part of this direct visualization also preliminary analysis and data reduction operations can be performed interactively. This primary and direct inspection allows studying and evaluating the full potential of acquired data sets such that data processing methods can be fine-tuned to squeeze out all needed information of interest. Ideally such improved data processing avoids subsequent surveying when output from already measured data sets is improved, resulting in reduced economical and environmental costs.

EPC RFID Technology for Library Applications

In this paper, EPC RFID (radio-frequency identifications) technology, which was developed originally for logistics and supply chain applications, is being investigated for the use of self-service library book checkout applications. To find out the key factors and also the interaction effects among the factors affecting the performance for the aforementioned applications, design of experiment techniques, especially the factorial design method, are being used to obtain the maximum amount of reliable information and at the same time to reduce the cost by minimising the number of runs needed in the experiment.

Development of a model application for WWW environments to sustain environmental education projects about the forest

Environmental education is an important means for the protection of the natural environment. Information and Communication Technologies (ICTs) support various educational tasks, especially with the aim of WWW environments. Information for environmental education projects about the forest can be acquired through Forest Service. Thus, it is developed a model web site to use as a template for any Forest Service unit, with organized material about the forest, about: historical information and status, forest as an ecosystem, functions and benefits, threats and effects, Forest Service, aims and targets and finally links for further information. The application is structured in a flexible, friendly and appealing arrangement for the enduser, comprises a large amount of reliable information, it meets the needs of various users and projects, it promotes environmental awareness and finally upgrades the role of Forest Service through its contribution in environmental education projects.

Benchmarking Merino studs : the Merinos to Match project

In Victoria, increasing the amount of reliable information on the genetic merit of Merino studs is important in reducing the risk faced by wool producers when they introduce new sources of genetic material into their flocks. The Merinos to Match project is a set of linked stud comparisons across Victoria designed to quickly lift the availability of reliable genetic information on Merino studs commonly used in the state. Details of the objectives, background, design, implementation and stakeholder involvement in the project are outlined in the paper. To date, 4 sites have been established in different wool growing areas of Victoria, evaluating 29 studs from 4 states.

Particle Sizing by Photon Correlation Spectroscopy. Part III: Mono and bimodal distributions and data analysis

AbstractThe possibilities and limitations of photon correlation spectroscopy (PCS) as a practical tool for particle sizing are reviewed. In this part the most frequently used methods of data analysis are briefly surveyed. The practical performances for the determination of particle size distributions were evaluated by a comparative study with different kinds of users (industrial and academic research groups and manufacturers). The PCS results were also compared with electron microscopy (EM) and static light scattering (SLS) results. Thereby it was confirmed that the amount of reliable information that can be obtained by PCS about particle size distributions with measuring times of the order of minutes is limited by the ill‐conditioning of the data inversion procedure, among other factors. Nevertheless, the information obtained from the PCS measurements agrees essentially with the EM and SLS results.

I. New developments in instrumentation. Introductory remarks

The purposes we envisaged that this meeting might serve was to provide, especially for biologists, a review of the current position in electron microscopy and an estimate of what further developments are likely or feasible in the fairly near future. We are very fortunate that so many distinguished workers in this field have been able to come to the meeting, so that they can, in section I, describe the capabilities of the most advanced forms of electron microscope at present available, and the additional devices and techniques that can be used to improve the quality of the information that the instrument gives us about a specimen. Then, in section II, we will hear about various advances in specimen preparation techniques, especially ones depending on physical approaches to the problem and, in section III, about various ways of handling and manipulating the information recorded in the electron micrographs themselves so that we can extract from them the maximum amount of reliable information about the three-dimensional structures which are being examined.

The mean lives of excited neon atoms

Since the first experiments by Wien many methods have been used to find the average lives of the excited states of different atoms. Most of these methods are applicable to particular atoms only, and the amount of reliable information in this field is still surprisingly meagre. The method described here depends in effect on the measurement of the lag which exists between the excitation and emission of light from atoms in a high-frequency discharge. This lag, or rather quantity actually measured, is itself a first approximation to the average life τ of the state concerned, and it is shown later how a more accurate value of τ may be deduced from it. Results are given for six excited states of the neon atom, but the method may be used for any substance whose spectrum can be obtained from a high-frequency discharge. The values of τ for neon range from 3·9 to 20·10 -8 seconds, and it is shown that lines originating from the same upper level lead to the same value of τ for that level.
