Phase space shifts in command structures in networked systems

This paper presents the rationale behind an important enhancement to the NATO SAS-050 approach space, combined with empirical results which take advantage of these enhancements. In Part 1 a new theoretical legacy for the NATO model is presented. This legacy inspires a number of developments which allow live data to be plotted into it, and we demonstrate that the model is well able to discriminate between alternative C2 structures. Part 2 illustrates this feature with multinational data from the ELICIT community. It is surprising to see that teams in both C2 and Edge conditions operate in broadly the same area of the phase space cube. The structure of the pre-ordained ELICIT ‘classic C2’ hierarchy and the deterministic nature of the shared task are put forward as explanations for this, and as future enhancements to the ELICIT paradigm

Fratricide: defective decision making

Motivation – to explore the applicability of a Human Factors methodology for the investigation of fratricide. Research approach – The EAST methodology was used to analyse an incident of fratricide and its ability to explore the Famous Five of Fratricide (F3) model was investigated. Findings/Design – the analysis revealed that EAST was able to provide explicit discussion of the Famous Five of Fratricide (F3) models five causal factors of communication, cooperation, coordination, schemata and situation awareness. Research limitations/Implications – the research explored a single case study and as such is couched at the initial phases of investigation. Originality/Value – the analysis provides a contribution to the knowledge urrounding fratricide both with respect to the novel application of the EAST methodology to an incident of fratricide, and also the causal factors identified by EAST within the fratricide incident. Take away message – the EAST methodology provides an innovative way of exploring causality in incidents of fratricide<br/

Multi-beam range imager for autonomous operations

For space operations from the Space Station Freedom the real time range imager will be very valuable in terms of refuelling, docking as well as space exploration operations. For these applications as well as many other robotics and remote ranging applications, a small potable, power efficient, robust range imager capable of a few tens of km ranging with 10 cm accuracy is needed. The system developed is based on a well known pseudo-random modulation technique applied to a laser transmitter combined with a novel range resolution enhancement technique. In this technique, the transmitter is modulated by a relatively low frequency of an order of a few MHz to enhance the signal to noise ratio and to ease the stringent systems engineering requirements while accomplishing a very high resolution. The desired resolution cannot easily be attained by other conventional approaches. The engineering model of the system is being designed to obtain better than 10 cm range accuracy simply by implementing a high precision clock circuit. In this paper we present the principle of the pseudo-random noise (PN) lidar system and the results of the proof of experiment

Harmonic? Anharmonic? Inharmonic?

In molecular spectroscopy, an anharmonic oscillator has a nonparabolic potential which results in a nonharmonic absorptionspectrum, but the same oscillator treated classically has a precisely harmonic vibrational spectrum. To avoid confusion, it is suggested that such an oscillator should simply be called nonlinear. The term “inharmonic” is suggested as an appropriate descriptor for classical oscillators, such as metal bars, that have nonharmonic vibrational spectra even in the linear limit of small vibrations

Servitisation and value co-production in the UK music industry

Since the rise of music on the internet, record companies have reported falling sales of physical products. This has occurred at a time when technology has radically increased choice, availability and the opportunity for the consumer to purchase music. As the music industry has moved from a product to a service business model, has the loss of sales meant they have not taken their customers with them? This paper provides a description of different music consumers based upon quantitative analysis of consumer characteristics. The paper then undertakes an exploration of the relationship between the consumer groups and their purchasing preference in relation to intangible ‘service’ purchase such as downloaded music and the purchase of a tangible physical product such as CDs or vinyl. In addition, we analyse the relationship between consumer types and their propensity to actively engage with music communities, such as through engagement with social media, and thus their willingness to coproduce greater value. Finally we explore the moderating effects of age and time devoted to listening to music on purchasing preferences and music discovery

Hyperhelices: a classical analog for strings and hidden dimensions

A hyperhelix is a structure consisting of a rod coiled into a helix, coiled into a helix,…, through a finite or even infinite number of orders. An examination of the transverse vibrations of such a structure shows that the macroscopic behavior is accounted for by waves on the rod that are confined to an extremely small range of wave numbers centered about a value equal to the reciprocal of the smallest helical radius involved. All other dynamical aspects of the behavior and their associated physical dimensions are completely hidden at the level of the final helix. It is suggested that the study of the dynamics of such a structure might provide a fruitful analogy for understanding the string theory

Subjective responses and eye fixations to visual displays of spatial sequences

In the selection of spatial sequences for this study importance was given to an understanding of the architect's design intentions, Chapters IV and VIII. The displays of the Sydney Opera House have revealed an incomplete structure, and the contrast of some completed spaces with substantial environmental noise of scaffold and workmens' ramps has been an important part of the study. In many cases the provision of a temporary path through space has been accepted by a group of subjects, and its importance "has been illustrated from eye fixations to the displays.In Displays 3, 4, 6, 7, 8, 9, 11 and 12 a conflict has not generally arisen between the designer's intentions of subjective experience and the responses of the subjects. But in Displays 1, 2, 5 and 10 the architect's design for the completed building and the recording of space in the incomplete building are at variance.The forty subjects who have taken part in the experiments represented a range of architectural training in addition to variations of personality and general conditioning. The group of subjects was not a sample of the general population, and for this reason the average creativity score was considerably higher than the average for the general population
