Using MapReduce Streaming for Distributed Life Simulation on the Cloud

Distributed software simulations are indispensable in the study of large-scale life models but often require the use of technically complex lower-level distributed computing frameworks, such as MPI. We propose to overcome the complexity challenge by applying the emerging MapReduce (MR) model to distributed life simulations and by running such simulations on the cloud. Technically, we design optimized MR streaming algorithms for discrete and continuous versions of Conway’s life according to a general MR streaming pattern. We chose life because it is simple enough as a testbed for MR’s applicability to a-life simulations and general enough to make our results applicable to various lattice-based a-life models. We implement and empirically evaluate our algorithms’ performance on Amazon’s Elastic MR cloud. Our experiments demonstrate that a single MR optimization technique called strip partitioning can reduce the execution time of continuous life simulations by 64%. To the best of our knowledge, we are the first to propose and evaluate MR streaming algorithms for lattice-based simulations. Our algorithms can serve as prototypes in the development of novel MR simulation algorithms for large-scale lattice-based a-life models.https://digitalcommons.chapman.edu/scs_books/1014/thumbnail.jp

Artefacts, Technicity and Humanisation industrial design and the problem of anoetic technologies

This thesis concerns the intellectual heritage and autonomy of West European and American industrial design as a discourse community at a moment when biotechnological developments are challenging the certainty of what it means to be human. Proceeding from the assumption that industrial design is an autonomous intellectual engagement played out through the interpretation of technology as an artefact, the thesis identifies how this is a critical moment for industrial designers, who appear to be unable to respond to a problem of the apparent disconnection and the progressive displacement of the human in reference to technology. The thesis identifies the cause of this as the understanding of the artefact, which has conventionally been placed at the centre of its analysis. The way that this has been constructed has not only impacted on design solutions but has led to a particular understanding of technology. It is this understanding of the artefact that has ceased to be sustainable and has precipitated the crisis. The thesis argues that, by revisiting the artefact as a mutable consequence of culture, it is possible to relieve the problem by opening up the scope for finding new methodological approaches. These can be used to develop design strategies that are sufficiently subtle and coherent in their terms to engage with the open complexity of future discussions of the distributed and enacted human

Molecular phylogeny of horseshoe crab using mitochondrial Cox1 gene as a benchmark sequence

An effort to assess the utility of 650 bp Cytochrome C oxidase subunit I (DNA barcode) gene in delineating the members horseshoe crabs (Family: xiphosura) with closely related sister taxa was made. A total of 33 sequences were extracted from National Center for Biotechnological Information (NCBI) which include horseshoe crabs, beetles, common crabs and scorpion sequences. Constructed phylogram showed beetles are closely related with horseshoe crabs than common crabs. Scorpion spp were distantly related to xiphosurans. Phylogram and observed genetic distance (GD) date were also revealed that Limulus polyphemus was closely related with Tachypleus tridentatus than with T.gigas. Carcinoscorpius rotundicauda was distantly related with L.polyphemus. The observed mean Genetic Distance (GD) value was higher in 3rd codon position in all the selected group of organisms. Among the horseshoe crabs high GC content was observed in L.polyphemus (38.32%) and lowest was observed in T.tridentatus (32.35%). We conclude that COI sequencing (barcoding) could be used in identifying and delineating evolutionary relatedness with closely related specie

Crab and cockle shells as heterogeneous catalysts in the production of biodiesel

In the present study, the waste crab and cockle shells were utilized as source of calcium oxide to transesterify palm olein into methyl esters (biodiesel). Characterization results revealed that the main component of the shells are calcium carbonate which transformed into calcium oxide upon activated above 700 °C for 2 h. Parametric studies have been investigated and optimal conditions were found to be catalyst amount, 5 wt.% and methanol/oil mass ratio, 0.5:1. The waste catalysts perform equally well as laboratory CaO, thus creating another low-cost catalyst source for producing biodiesel. Reusability results confirmed that the prepared catalyst is able to be reemployed up to five times. Statistical analysis has been performed using a Central Composite Design to evaluate the contribution and performance of the parameters on biodiesel purity

Patterns of Science: Developing Knowledge for a World Community at Unesco

In the aftermath of World War II, many internationalists diagnosed the fundamental cause of international conflict as humanity’s failure to realize the ideals of a world community grounded in global political institutions and common values. To prevent an apocalyptic third world war, internationalists affiliated with the United Nations Educational, Scientific and Cultural Organization (Unesco) identified two ways science could engineer a peaceful and prosperous world community: “technologically, by changing the material conditions of life, work and production; and intellectually, by changing the way in which men think.” Grounded in archival research in four countries, “Patterns of Science” explores both strategies through studies of Unesco’s environmental and social sciences programs. Environmental scientists emphasized the need to balance nature’s books by adapting the pattern of natural resources exploitation to the requirements of global population growth. They conceived of scientifically guided development as a moral equivalent of war that could unite an international army for the conquest of nature. Social scientists stressed the importance of reforming parochial cultural patterns to construct “the defences of peace in the minds of men.” By facilitating intercultural understanding, social scientists would help nations realize the ideal of “unity in diversity.” The goal of both strategies was to produce objective global knowledge that would make the world scale real—“in the minds of men” as well as for politicians and planners. “Patterns of Science” reveals how internationalist scientists attempted to navigate the politics of the cold war, decolonization, and bureaucratic rivalries through case studies that demonstrate the interaction of international, national, and local scales. These cases range from the Los Angeles School District’s implementation of a “Unesco program” during the height of McCarthyism to the establishment of a university chair of race relations in Southern Rhodesia, and from an arid lands research program that pitted “men against the desert” to the production of a Soil Map of the World. Although often mired in controversy or dismissed as naïve, Unesco’s work produced an international community of experts and global social and environmental knowledge that proved crucial to the emerging imperative for sustainable development in the early 1970s
