This paper is an attempt to further our understanding of mechanisms conceived of as ontologically separable from laws. What opportunities are there for a mechanistic perspective to be independent of, or even more fundamental than, a law perspective?
In the ancient world, writings were routinely delivered orally by trained lectors. An important task for the lector was to give voice to the silent, close-knit lines of scriptio continua manuscripts. This was made possible by the fact that the oral structure and aural character were encoded into the text. This paper analyzes the sound structure of John 1:19–51 and identifies what aural features w
In this paper we present a gradient method to iteratively update local controllers of a distributed linear system driven by stochastic disturbances. The control objective is to minimize the sum of the variances of states and inputs in all nodes. We show that the gradients of this objective can be estimated distributively using data from a forward simulation of the system model and a backward simul
Recursive state estimation is considered for discrete time linear systems with mixed process and measurement disturbances that have stochastic and (convex) set-bounded terms. The state estimate is formed as a linear combination of initial guess and measurements, giving an estimation error of the same mixed type (and causing minimal interference between the two kinds of error). An ellipsoidal over-
In this paper our objective is to discuss the manner in which our engagement with applied cultural analysis has spurred us to reassess a number of fundamental underlying concepts and practices of ethnological and anthropological work. The paper opens by explaining how our engagement with applied research (and education) has changed our conceptual framing of ethnography and inspired us to new theor
This paper introduces a new estimate of core inflation. Core inflation is a real time estimate of monetary inflation. Most existing core inflation estimate do not account for persistent relative price changes and are therefore likely to be poor estimates of the underlying monetary inflation rate. The proposed core inflation estimate estimates core inflation by first estimating the inflation signal
We develop a model to analyze the growth of social organizations as a spatially nested mixed-influence diffusion process. Drawing on gravity models and threshold models, we split the social system into social units and model the diffusion process as a system of differential equations. The diffusion of a new organizational form in a social unit is a function of an internal process within the unit a
This paper gives a brief introduction to the TrueTime simulator and then gives several examples on how TrueTime can be used to simulate networked control systems. Among the examples are time-triggered and event-based networked control and AODV routing in wireless ad-hoc networks.
DNA is presently at the centre of a storm. On the one hand, the breathtaking development of DNA related sciences during the last decades led to a technological and medical revolution. Due to the far reaching possibilities connected to this technology, it is the focus of many people’s interest and one source of the hope that one day we will find cures for terrible illnesses. Unsurprisingly, DNA rel
Since ancient times, reeds have been used as a low-tech building material in several construction purposes. Reed is a natural building materials that possess many useful benefits in contemporary building practices. Reeds grow around lakes, swamps and other water canals and have no environmental impact if dismantled after construction as they are biodegradable. Reeds are also easy to cut and handle
