Dual-Aspect Monism, Mind-Matter Complementarity, Self-Continuity and Evolutionary Panentheism
Physicalism as a worldview and framework for a mechanistic
and materialist science seems not to have integrated the tectonic shift
created by the rise of quantum physics with its notion of the personal
equation of the observer. Psyche had been deliberately removed from a
post-Enlightenment science. This paper explores a post-materialist
science within a dual-aspect monist conception of nature in which both
the mental and the physical exist in a relationship of complementarity
so that they mutually exclude one another and yet are together
necessary to explain Reality while being irreducible to one another.
Both mind and matter emerge from an underlying holistic domain
known as the unus mundus in the Jung-Pauli formulation or as the
analogous implicate order in the framing of physicist David Bohm and
his colleagues. Kuhnian anomalies such as the role of reflective
consciousness in evolution, and phenomena including so-called “near
death experiences” (NDEs), are considered from the perspective of
dual-aspect monism in conjunction with an emerging evolutionary panentheism
Radiation Risks and Mitigation in Electronic Systems
Electrical and electronic systems can be disturbed by radiation-induced
effects. In some cases, radiation-induced effects are of a low probability and
can be ignored; however, radiation effects must be considered when designing
systems that have a high mean time to failure requirement, an impact on
protection, and/or higher exposure to radiation. High-energy physics power
systems suffer from a combination of these effects: a high mean time to failure
is required, failure can impact on protection, and the proximity of systems to
accelerators increases the likelihood of radiation-induced events. This paper
presents the principal radiation-induced effects, and radiation environments
typical to high-energy physics. It outlines a procedure for designing and
validating radiation-tolerant systems using commercial off-the-shelf
components. The paper ends with a worked example of radiation-tolerant power
converter controls that are being developed for the Large Hadron Collider and
High Luminosity-Large Hadron Collider at CERN.Comment: 19 pages, contribution to the 2014 CAS - CERN Accelerator School:

Risk and Machine Protection for Stored Magnetic and Beam Energies
Risk is a fundamental consideration when designing electronic systems. For
most systems a view of risk can assist in setting design objectives, whereas
both a qualitative and quantitative understanding of risk is mandatory when
considering protection systems. This paper gives an overview of the risks due
to stored magnetic and beam energies in high-energy physics, and shows how a
risk-based approach can be used to design new systems mitigating these risks,
using a lifecycle inspired by IEC 61508. Designing new systems in high-energy
physics can be challenging as new and novel techniques are difficult to
quantify and predict. This paper shows how the same lifecycle approach can be
used in reverse to analyse existing systems, following their operation and
first experiences.Comment: 19 pages, contribution to the 2014 CAS - CERN Accelerator School:

How Equilibrium Prices Reveal Information in Time Series Models with Disparately Informed, Competitive Traders
Accommodating asymmetric information in a dynamic asset pricing model is technically challenging due to the problems associated with higher-order expectations. That is, rational investors are forced into a situation where they must forecast the forecasts of other agents. In a dynamic setting, this problem telescopes into the infinite future and the dimension of the relevant state space approaches infinity. By using the frequency domain approach of Whiteman (1983) and Kasa (2000), this paper demonstrates how information structures previously believed to preserve asymmetric information in equilibrium, converge to a symmetric information, rational expectations equilibrium. The revealing aspect of the price process lies in the invertibility of the observed state space, which makes it possible for agents to infer the economically fundamental shocks and thus eliminating the need to forecast the forecasts of others.Asset Pricing, Asymmetric Information
Optimal Defensive Strategies in One-Dimensional RISK
We consider a one-dimensional version of the board game RISK and discuss the problem of how a defending player might choose to distribute his armies along a chain of territories in order to maximize the probability of survival. In particular, we analyze a Markov chain model of this situation and run computer simulations in order to make conjectures as to the optimal strategies. The latter sections of the paper analyze this strategy rigorously and use results on recurrence relations and probability theory in order to prove a related result
NASTRAN application for the prediction of aircraft interior noise
The application of a structural-acoustic analogy within the NASTRAN finite element program for the prediction of aircraft interior noise is presented. Some refinements of the method, which reduce the amount of computation required for large, complex structures, are discussed. Also, further improvements are proposed and preliminary comparisons with structural and acoustic modal data obtained for a large, composite cylinder are presented
