This paper describes the experience from several ooerings of a Software Requirements course based on the Object Modeling Technique by Rumbaugh & al. The paper describes the organization of the course, which includes a semester project carried out by groups of 3-4 students. Descriptions of 20 such projects are given, most of which were based on ideas from the student teams.

In the second edition of his Essay on the Principle of Population, Malthus included twelve chapters that offer a remarkable description of population dynamics from all corners of the world. His discussion of (sub-Saharan) Africa was almost entirely based on the travel accounts of James Bruce and Mungo Park, two late eighteenth century British explorers. In this essay, I introduce these sources ...

He married, in 1870, Miss S. D. Jones, and took a farm near ?Kingsteignton, Devonshire. He entered at the Bristol Medical School when he was over thirty vears of age. He then went to Edinburgh and got Qualified in 1884. Besides his work as a general practitioner, he was Public Vaccinator for the Clifton District, and he attended gratuitously, for more than twenty-five years, the inmates of St. ...

Testing is an obligatory step in developing multi-agent systems. For testing multi-agent systems in virtual, dynamic environments, simulation systems are required that support a modular, declarative construction of experimental frames, that facilitate the embeddence of a variety of agent architectures, and that allow an efficient parallel, distributed execution. We introduce the system James (A...

I thank Drs. King and Cleary for their comments on my paper. They correctly point out the possibility of scattering in the forward direction from small irregularities (close to the size of a wavelength) near the crust. They then suggest that this mechanism can explain all precursors o f P 'P ' except for the P'650P' reflection, and that the reflection scattering hypothesis in Whitcomb (1973a) i...

In the industrial engineering community, it’s a well-known adage that focusing on process can help achieve better results. In this second of a series of papers, we’ll focus on the process of simulation testing and outline how improving your testing process can lead to better results for your projects. We’ll consider model building as a software development exercise, and discuss how best practic...

In his 1981 Baseball Abstract [8], Bill James posed the following problem: suppose two teams A and B have winning percentages a and b, respectively, having played equally strong schedules in a game such as baseball where there are no ties. If A and B play each other, what is the probability p(a, b) that A wins? This question is perhaps more relevant to other sports, because in baseball the outc...

James Tanner spent much of his childhood abroad, in the baggage train of the British Army; when he was 9 years old the family returned to their home in east Devon and he began his schooling. He attended Marlborough College from 1934 to 1938 on a scholarship reserved for the sons of Army officers. Having specialised first in modern languages and then in mathematics and engineering, he found hims...

Hamilton begins his criticism by stating that there is a philosophical distinction between the two methods for dating cycles and concludes that the method we use “leaves vague and intuitive exactly what this algorithm is intended to measure”. Nothing is further from the truth. Ask yourself, what is a recession? Common usage suggests that it is a decline in the level of economic activity that la...

The idea that geography affects economic performance is an old one. Easterly and some other economists have taken a particular position about the relationship between geography and development. They too have recognized the high correlation of a country’s poverty with being in a malaria-transmission region, or being landlocked, or being in an ecological zone leading to low food productivity. Tho...
