experience and, with Dr.Roy Black, had developed a beef cattle management model at Michigan State University (Fox and Black, 1984). The Michigan State University model was later programmed into Basic for a Radio Shack TRS 80 and became Cornell Cattle System 1. Charlie had little modeling experience, but always had an appreciation for the value of computers in solving complex mathematical problems as evidenced by the acquisition at the University of Maine of a computer from the nose cone of a Trident missile (Hoover, 2003). These men recognized that current ruminant nutrition models, such as the NRC models, lacked integration between the animal and its environment and lacked integration between physiological functions and metabolic processes.

This paper presents the Visual Haskell language. Visual Haskell is intended as i) a means of visualising Haskell programs, and ii) as a complementary programming notation to standard Haskell. The syntax of Visual Haskell is specified by first giving a translation from Haskell into an intermediate

The report presents a model to investigate the collective behaviour of a colony when memory of the agents interferes with the usual interaction between individuals. The approach is developed in the framework of a simple situation consisting in tandem recruitment in a population of conservative agents but it is susceptible to be applied also to a wider range of problems. The principle of the method is inspired by the work of Leuthausser and Tarazona who developed the correspondence between a model for macromolecular time evolution and the equilibrium statistical mechanics of a higher dimensional Ising system. 1 Introduction Most investigations on the collective behaviour of social groups assume that the individuals are memoryless with the consequence that the time evolution of a population is exclusively ruled by the interaction mechanisms between the individuals. This report proposes a technique to combine, within the same model, both the interactions between individuals and the mem...

Abstract. Reservoir Computing is a new paradigm to use artificial neural networks. Despite its promising performances, it has still some drawbacks: as the reservoir is created randomly, it needs to be large enough to be able to capture all the features of the data. We propose here a method to start with a large reservoir and then reduce its size by pruning out neurons. We then apply this method on a prototypical and a real problem. Both applications show that it allows to improve the performance for a given number of neurons. 1

Abstract. This report presents work done to implement the deque class for the Copenhagen STL. The ideas of two articles are explored and combined in an at-tempt to implement a data structure that improves the running times of the core deque operations compared to an existing implementation. Even
