+Robust Sensing in a Distributed Environment
 ===== Abstract =====
-In this paper, we describe a system in the movable feast machine framework of Artificial Life. The movable feast machine (MFM) is a recent development in the artificial life community, intended to describe a more intuitive framework for computation using a type of cellular automata. We present a design for a set of MFM elements which construct a phased sensor array to sense incoming data. The system as a whole gathers spatially-oriented data transmissions and tells us from where the data is coming. This can enable users to do things like analyze incoming data or to establish communications pathways.
+In this paper, we present a design for a set of Movable Feast Machine (MFM) elements which construct a phased sensor array to sense incoming data. The system gathers spatially-oriented data transmissions and tells us from where the data is coming. This can enable users to analyze incoming data, or to establish communications pathways. The design includes parameters which regulate the density and directionality of the array. Here, we show that certain parameters allow the data to be sensed accurately without too much data loss. Specifically, we illustrate the trade-off between data loss and sensing capacity as a function of these parameters.
-(needs a trade-off; accuracy versus directional data, etc.)(More about properties to make it science)
 ===== Methods =====
 Any sensor system needs to have some sort of target object to sense. In this work, our target objects are called Light particles. These are a very simple pair of light atoms, driving themselves forward in a given direction. The Light particles are emitted at a steady rate by Emitter atoms. The locations of these Emitters are the main things we want to be able to sense with our system. As such, each experiment described here has a predetermined set of emitter locations, making it easier to compare the performance of different parameter values, as we do here.
-The Light particles are what we should sense, but they must interact with another element if we want to do this. In this setup, we use a number of Box atoms for this purpose. Box atoms construct a small N * M rectangular box, which will serve as the effective range for our sensors. Emitters outside of the box are ignored in this work to narrow down the scope of our analyses.

Box atoms construct a small N * M rectangular box, which will serve as the effective range for our sensors. The Box atoms in this wall each record the number of Light particles which strike them from the inside, while also disposing of these particles by deleting them. Emitters outside of the box are ignored in this work to narrow down the scope of our analyses.
 The Box alone serves as a very rough sensor, but it is incapable of distinguishing several different directions from each other, depending on how close to the Box's wall a given emitter is situated. See Figure XXX for an example of this phenomenon. The naked Box-as-sensor will serve as the control experiment against which the performance of other designs is measured.
