Digital Preservation (Fairdata-PAS): Guidelines for UH Evaluators
Finnish Ministry of Education and Culture has established Fairdata-PAS service for Finnish research organizations for long-time storing the nationally most significant research data. Fairdata-PAS is meant for digital preservation of research data for several decades, or even centuries. This document gives guidelines for University of Helsinki evaluators when assessing value of the data
Prop-fan data support study
Updated parametric prop-fan data packages are presented and the rationale used in developing the new prop-fan data is detailed. These data represent Hamilton Standard's projections of prop-fan characteristics for aircraft that are expected to be in-service in the 1985 to 1990 time frame. The basic prop-fan configuration was designed for efficient cruise operation at 0.8 Mach number and 10,668M altitude. The design blade tip speed is 244 mps and the design power loading is 301 KW/M squared
Oyster RNA-seq data support the development of Malacoherpesviridae genomics
The family of double-stranded DNA (dsDNA) Malacoherpesviridae includes viruses
able to infect marine mollusks and detrimental for worldwide aquaculture production.
Due to fast-occurring mortality and a lack of permissive cell lines, the available data
on the few known Malacoherpesviridae provide only partial support for the study
of molecular virus features, life cycle, and evolutionary history. Following thorough
data mining of bivalve and gastropod RNA-seq experiments, we used more than
five million Malacoherpesviridae reads to improve the annotation of viral genomes
and to characterize viral InDels, nucleotide stretches, and SNPs. Both genome and
protein domain analyses confirmed the evolutionary diversification and gene uniqueness
of known Malacoherpesviridae. However, the presence of Malacoherpesviridae-like
sequences integrated within genomes of phylogenetically distant invertebrates indicates
broad diffusion of these viruses and indicates the need for confirmatory investigations.
The manifest co-occurrence of OsHV-1 genotype variants in single RNA-seq samples of
Crassostrea gigas provide further support for the Malacoherpesviridae diversification. In
addition to simple sequence motifs inter-punctuating viral ORFs, recombination-inducing
sequences were found to be enriched in the OsHV-1 and AbHV1-AUS genomes.
Finally, the highly correlated expression of most viral ORFs in multiple oyster samples
is consistent with the burst of viral proteins during the lytic phase
Onboard Experiment Data Support Facility (OEDSF): Conceptual design study
The Onboard Experimental Data Support Facility (OEDSF) is an inflight data processor based on a totally new architecture specifically developed to cost-effectively process the data of Shuttle payloads sensors. Processing data onboard fills the following needs: (1) reduction of data bulk by conversion to information (2)quick-look for evaluation, interactive operation, etc. (3) real-time computation of engineering representation of sensed phenomena. For example: Value of backscatter coefficient (sigma) of a scatterometer as a function of latitude and longitude (4) exploitation of the real-time availability of ancillary data, thereby obviating the need for time-tagging, recording, and recorrelation and (5) providing data or information immediately usable by the experimenter or user. The OEDSF is made up of modular and cascadable matrix processors. Each matrix has been sized to process the data of a full typical shuttle payload. Cost analyses indicate that significant savings are realized by processing data with the OEDSF compared with conventional ground facilities
Onboard Experiment Data Support Facility
An onboard array structure has been devised for end to end processing of data from multiple spaceborne sensors. The array constitutes sets of programmable pipeline processors whose elements perform each assigned function in 0.25 microseconds. This space shuttle computer system can handle data rates from a few bits to over 100 megabits per second
Cost Decision Support in Product Design
The constraints addressed in decision making during product design, process planning and production planning determine the admissible solution space for the manufacture of products. The solution space determines largely the costs that are incurred in the production process. In order to be able to make economically sound decisions, costing data support must be integrated into the decision making processes. Regarding product design, the designer must be supplied with transparent costing data, that is ready for direct application. In this paper a functional architecture for costing data support during product design, as well as a corresponding data structure are presented

Vibrational lifetimes and intramolecular energy randomisation of polyatomic molecules in liquids
Transient experiments with picosecond laser pulses give valuable information on the dynamic properties of polyatomic molecules in the electronic ground state. In small molecules the decay of vibrational energy occurs via individual lower energy states; in large molecules the experimental data support a statistical model
