Flight software requirements and design support system

The desirability and feasibility of computer-augmented support for the pre-implementation activities occurring during the development of flight control software was investigated. The specific topics to be investigated were the capabilities to be included in a pre-implementation support system for flight control software system development, and the specification of a preliminary design for such a system. Further, the pre-implementation support system was to be characterized and specified under the constraints that it: (1) support both description and assessment of flight control software requirements definitions and design specification; (2) account for known software description and assessment techniques; (3) be compatible with existing and planned NASA flight control software development support system; and (4) does not impose, but may encourage, specific development technologies. An overview of the results is given

A Historical Perspective on Runtime Assertion Checking in Software Development

This report presents initial results in the area of software testing and analysis produced as part of the Software Engineering Impact Project. The report describes the historical development of runtime assertion checking, including a description of the origins of and significant features associated with assertion checking mechanisms, and initial findings about current industrial use. A future report will provide a more comprehensive assessment of development practice, for which we invite readers of this report to contribute information

The bracteatus pineapple genome and domestication of clonally propagated crops

Domestication of clonally propagated crops such as pineapple from South America was hypothesized to be a 'one-step operation'. We sequenced the genome of Ananas comosus var. bracteatus CB5 and assembled 513 Mb into 25 chromosomes with 29,412 genes. Comparison of the genomes of CB5, F153 and MD2 elucidated the genomic basis of fiber production, color formation, sugar accumulation and fruit maturation. We also resequenced 89 Ananas genomes. Cultivars 'Smooth Cayenne' and 'Queen' exhibited ancient and recent admixture, while 'Singapore Spanish' supported a one-step operation of domestication. We identified 25 selective sweeps, including a strong sweep containing a pair of tandemly duplicated bromelain inhibitors. Four candidate genes for self-incompatibility were linked in F153, but were not functional in self-compatible CB5. Our findings support the coexistence of sexual recombination and a one-step operation in the domestication of clonally propagated crops. This work guides the exploration of sexual and asexual domestication trajectories in other clonally propagated crops

Genomic signatures of heterokaryosis in the oomycete pathogen Bremia lactucae.

Lettuce downy mildew caused by Bremia lactucae is the most important disease of lettuce globally. This oomycete is highly variable and rapidly overcomes resistance genes and fungicides. The use of multiple read types results in a high-quality, near-chromosome-scale, consensus assembly. Flow cytometry plus resequencing of 30 field isolates, 37 sexual offspring, and 19 asexual derivatives from single multinucleate sporangia demonstrates a high incidence of heterokaryosis in B. lactucae. Heterokaryosis has phenotypic consequences on fitness that may include an increased sporulation rate and qualitative differences in virulence. Therefore, selection should be considered as acting on a population of nuclei within coenocytic mycelia. This provides evolutionary flexibility to the pathogen enabling rapid adaptation to different repertoires of host resistance genes and other challenges. The advantages of asexual persistence of heterokaryons may have been one of the drivers of selection that resulted in the loss of uninucleate zoospores in multiple downy mildews

The Penn State ORSER system for processing and analyzing ERTS and other MSS data

The author has identified the following significant results. The office for Remote Sensing of Earth Resources (ORSER) of the Space Science and Engineering Laboratory at the Pennsylvania State University has developed an extensive operational system for processing and analyzing ERTS-1 and similar multispectral data. The ORSER system was developed for use by a wide variety of researchers working in remote sensing. Both photointerpretive techniques and automatic computer processing methods have been developed and used, separately and in a combined approach. A remote Job Entry system permits use of an IBM 370/168 computer from any compatible remote terminal, including equipment tied in by long distance telephone connections. An elementary cost analysis has been prepared for the processing of ERTS data

Desire to belong : contesting the view of Irish travellers as Deleuzian and Guattarian nomads

In my thesis I have discussed whether Irish Travellers could be considered to be Nomads in a way that French theorists Gilles Deleuze and Felix Guattari have developed the concept. Nomads in this context challenge and object the normative order set by the state and the mainstream society. My research is constructed around the concept of ethnicity and namely what Irish Travellers hope to gain with the ethnic status and how this relates to the ways how Travellers are controlled by the state. As a primary material I have used a report made by a Traveller support group which discusses the challenges which Irish Travellers are facing in today’s Ireland and as a method I have used critical discourse analysis. In my thesis I have discussed how physical nomadism plays a key role constructing Traveller identity and how physical nomadism relates to Deleuze's and Guattari's ideas about Nomadism. According to my findings Irish Travellers have a strong desire to be accepted by the mainstream society and to have an access to the resources controlled by the state. Irish Travellers want to be a part of the mainstream society hence keeping their own culture and be a part of the political process of the state. In the main chapters of my thesis I employ also other Deleuzian and Guattarian concepts like Faciality, Minority and Becoming in order to outline Travellers' relationship to Nomadism. The conclusion in my thesis is that Irish Travellers cannot be considered Deleuzian and Guattarian Nomads. I have based this argument on my findings that according to my primary material Travellers have a strong desire to be included to the structures of the state and be respected by the main society. These require that Irish Travellers follow the rules set by the state and the mainstream society. There is however a possibility for Travellers to change the system in the context of becoming; by challenging the normative order by entering the state structures and the mainstream society

Software development environments: Present and future, appendix D

Computerized environments which facilitate the development of appropriately functioning software systems are discussed. Their current status is reviewed and several trends exhibited by their history are identified. A number of principles, some at (slight) variance with the historical trends, are suggested and it is argued that observance of these principles is critical to achieving truly effective and efficient software development support environments
