Product Development Process for Small Unmanned Aerial Systems

The DoD has recognized the need for persistent Intelligence, Surveillance and Reconnaissance (ISR) over the last two decades. Recent developments with commercial drones have changed the market structure; there is now a thriving and extensive market base for drone based remote sensing. This research provides system engineering methods to support the DoD use of this burgeoning market to meet operational ISR needs. The three contributions of this research are: a process to support Small Unmanned Aerial Systems (SUAS) design, tools to support the design process, and tools to support risk assessment and reduction for both design and operations. The process and tools are presented via an exemplar design for an ISR SUAS mission. The exemplar design flows from user needs through to an allocated baseline with an assessment of system reliability based on a compilation of commercial component reliability and failure modes

"With the peristaltic gurglings of this gastēr-investigative procedural – a soooo welcomed addition to the ballooning corpus of slot-versatile bad eggs The Confraternity of Neoflagellants (CoN) – [users] and #influencers everywhere will be belly-joyed to hold hands with neomedieval mutter-matter that literally sticks and branches, available from punctum in both frictionless and grip-gettable boke-shaped formats. A game-changer in Brownian temp-controlled phoneme capture, ρan-ρan’s writhing paginations are completely oxygen-soaked, overwriting the flavour profiles of 2013’s thN Lng folk 2go with no-holds-barred argumentations on all voice-like and lung-adjacent functions. Rumoured by experts to be dead to the World™, CoN has clearly turned its ear canal arrays towards the jabbering OMFG feedback signals from their scores of naive listeners, scrapping all lenticular exegesis and content profiles to construct taped-together vernacular dwellings housing ‘shrooming atmospheric awarenesses and pan-dimensional cross-talkers, making this anticipatory sequel a serious competitor across ambient markets, and a crowded kitchen in its own right. An utterly mondegreen-infested deep end may deter would-be study buddies from taking the plunge, but feet-wetted Dog Heads eager to sniff around for temporal folds and whiff past the stank of hastily proscribed future fogs ought to ©k no further than the roll-upable-rim of ρan-ρan’s bleeeeeding premodern lagoon. Arrange yerself cannonball-wise or lead with the #gut and you’ll be kersplashing in no times.

Colour out of space: colour in the construction and usage of monuments of Neolithic Atlantic Europe.

Colour is a fundamental human experience – if not a universally constant one. There are, after all, individuals who are colour-blind to various degrees, or even those that see extra colours. However, there is something about the perception and categorisation of colour that is near uniform across humanity, as evidenced by Berlin and Kay’s Basic Color Terms and studies into the key mechanisms of colour vision. Deeper still, it seems to be the case that specific colours re-appear in human art, iconography, ritual and folklore as a leitmotif running through our cultural evolution; that is, the colours red, white, and black. Evidence for this significant triad, as well as other colours showing repeated and deliberate selection, has been gathered and analysed. A summary of the literature on this is presented in this, along with a review with existing work on colour, and why the materiality and material semiotics of stone are important to this research. The aim of this research is to survey a sample of Neolithic monuments across Atlantic Europe, and see if there are any commonalities, significant patterns, and demonstrable signs of specific colour selection that may hint at colour being an important part of Neolithic cosmology – regionally, locally, or culturally. There has been some work touching upon this concept, most recently and notably at the Clava Cairns and sites on Arran; this study will develop this existing research and deepen the understanding of colour use in the Neolithic. In order to see if the fascinating possibilities raised in these works has broader Neolithic context, this research will study sites in similar levels of detail at locations across Atlantic Europe. This will include many styles of monument, from stone circles to passage graves to long barrows to stone rows, in order to evaluate colour significance across a broad range of monument building traditions. Colour was recorded via both human perception and through the use of a digital recording device, custom designed for this project. Recording these colours using a digital tool achieves two things: namely, to go some way towards compensating for the fallibility of the human visual cortex, and to provide a vector for the material properties to speak without being directly interpreted by a human intermediary. This taking into account of the material agency of the stones themselves played a key role in understanding the networks of influence that colours may have had on Neolithic peoples, and how this could have affected their cosmologies. The main stage of this research is six case studies of groupings of Neolithic monuments across the Atlantic façade of north western Europe. Discussion is focused through a lens of these findings along with studies into ethnographic parallels on colour use, stone provenance, and materiality among early farming societies. Using the methodology refined by the initial pilot studies, these six regions are examined for patterns and connections, and analysed both within their own regions and in a wider context, to enable statements on the importance of colour to Neolithic monument builders to be made

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
