...Chaotic Growth with the Logistic Model of P.-F. Verhulst Hugo Pastijn Department of Mathematics, Royal Military Academy B-1000 Brussels, Belgium Hugo.Pastijn@rma.ac.be Summary. Pierre-Fran¸ois Verhulst was born 200 years ago. After a short biograc phy of P.-F. Verhulst in which the link with the Royal Military Academy in Brussels is emphasized, the early history of the so-called “Logistic Model” is described. The relationship with older growth models is discussed, and the motivation of Verhulst to introduce different kinds of limited growth models is presented. The (re-)discovery of the chaotic behaviour of the discrete version of this logistic model in the late previous century is reminded. We conclude by referring to some generalizations of the logistic model, which were used to describe growth and diffusion processes in the context of technological innovation, and for which the author studied the chaotic behaviour by means of a series of computer experiments, performed in the eighties of last century by means of the then emerging “micro-computer” technology. 1 P.-F. Verhulst and the Royal Military Academy in Brussels In the year 1844, at the age of 40, when Pierre-Fran¸ois Verhulst on November c 30 presented his contribution to the “M´moires de l’Acad´mie” of the young e e Belgian nation, a paper which was published the next year in “tome XVIII” with the title: “Recherches math´matiques sur la loi d’accroissement de la e population” (mathematical investigations of the law of...

...of income, and, in addition, work brings moral satisfaction. Thus, the loss of a job not only leads to a reduction of the current material standard of living, but also to the emergence of uncertainty about the future, as well as feelings of worthlessness causes serious psychological trauma. Therefore, one can hardly call the country a developed and civilized unless its citizens and each citizen in particular, are unable to support themselves and be useful in society. From all the above we can conclude that the problem of employment and unemployment rate today is a very important issue, as Russia is at the forefront of unemployment among European countries. The purpose of this course work - study and analysis of the problem of unemployment and ways to overcome it, Russia Analysis of labor markets and the Krasnodar Territory. For its consideration of this problem you need to solve a number of problems: • disclose the concept of the labor market, employment and unemployment; • analyze the work of the public employment service; • reveal the main problems of the Russian labor market; • conduct studies major opportunities to ensure employment in the country and in the region.

...An integrated approach or understanding of earth including the oceans is vital if we have to effectively and sustainably manage earth’s energy, water, mineral, soil and coastal resources for our future generations. A stand-alone view of various phenomena will not serve any purpose as any independent model is unable to sustain the variability of the complexities involved in the earth and ocean sciences, which are gradually converging. It has therefore become imperative to understand the interdependence and coupling of geological sciences and oceanography. The combined approach to earth and ocean sciences is also the key to predicting and managing natural disasters or hazards like earthquakes, cyclones, floods, tsunami, etc. In this context, in a significant development in India, a Ministry of Earth Sciences (MoES) was formed in July 2006 by restructuring the former Ministry of Ocean Development. The MoES deals with matters relating to meteorology, seismology, climate and environmental science and related earth sciences including ocean science and technology. It facilitates an integrated view of earth systems viz., ocean, atmosphere and land to provide best possible services in respect of ocean resources, ocean state, monsoon, cyclone, earthquake, tsunami, climate change, etc. The MoES oversees research in earth system sciences, forecast monsoons and other climate parameters, ocean state, earthquakes, tsunamis and earth science phenomena. The ministry also supports industry...

...REVISITING MARKET EFFICIENCY: THE STOCK MARKET AS A COMPLEX ADAPTIVE SYSTEM by Michael J. Mauboussin, Credit Suisse First Boston t is time to shift the emphasis of the debate about market efficiency. Most academics and practitioners agree that markets are efficient by a reasonable operational criterion: there is no systematic way to exploit opportunities for superior gains. But we need to reorient the discussion to how this operational efficiency arises. The crux of the debate boils down to whether we should consider investors to be rational, well informed, and homogeneous—the backbone of standard capital markets theory—or potentially irrational, operating with incomplete information, and relying on varying decision rules. The latter characteristics are part and parcel of a relatively newly articulated phenomenon that researchers at the Santa Fe Institute and elsewhere call complex adaptive systems. Why should corporate managers care about how market efficiency arises? In truth, executives can make many corporate finance decisions independent of the means of market efficiency. But if complex adaptive systems do a better job explaining how markets work, there are critical implications for areas such as risk management and investor communications. I Take, for example, the earnings expectations game.1 In a complex adaptive system, the sum is greater than the parts. So it is not possible to understand the stock market by paying attention to individual analysts. Managers...

...1/ ENERGY BANDS IN SOLIDS In this chapter we begin with a review of the basic atomic properties of matter leading to discrete electronic energy levels in atoms. We find that these energy levels are spread into energy bands in a crystal. This band structure allows us to distinguish between an insulator, a semiconductor, and a metal. 1-1 CHARGED PARTICLES The charge, or quantity, of negative electricity and the mass of the electron have been found to be 1.60 X 10- 19 C (coulomb) and 9.11 X 10- 31 kg, respectively. The values of many important physical constants are given in Appendix A, and a list of conversion factors and prefixes is given in Appendix B. Some idea of the number of electrons per second that represents current of the usual order of magnitude is readily possible. F'or example, since the charge per electron is 1.60 X 10- 19 C, the number of electrons per coulomb is the reciprocal of this nutnber, or approximately, 6 X 10 18 Further, since a current of 1 A (ampere) is the flow of 1 Cis, then a current of only 1 pA (1 picoampere, or 10- 12 A) represents the motion of approximately 6 million electrons per second. Yet a current of 1 pA is so small that considerable difficulty is experienced in attempting to measure it. The charge of a positive ion is an integral multiple of the charge of the electron, although it is of opposite sign. For the case of singly ionized particles, the charge is equal to that of the electron. For the case of doubly ionized particles...

DECLARATION I, [type your full first names and surname here], declare that the contents of this dissertation/thesis represent my own unaided work, and that the dissertation/thesis has not previously been submitted for academic examination towards any qualification. Furthermore, it represents my own opinions and not necessarily those of the University. Signed __________________ Date _________________ Abstract Windsor Airmotive Asia Pvt Ltd is the leading repair and overhaul shop for CFM56-3/-5/-7 series turbine engine components. During development of a new repair scheme, to replace the inner inducer and outer inducer of the Forward Inner Nozzle Supports (FINS), a major challenge was encountered at the Electric Discharge Machine (EDM). A trial done on a scraped part revealed that 112 vanes have to be aligned before it can be machined by EDM to the inducer. By introducing a semi-automated machining fixture, the alignment of the vanes will be made easier, on top of increasing the utilization of the EDM by 20%. The aim of this project is to develop a machining fixture for the EDM so that the alignment of 112 vanes...

Nonetheless the failure to manage this enormous amount of data, and to swiftly acquire the information that is relevant to any particular question, as the volume of information rises, demonstrates to be a distraction and a liability, rather than an asset. This paradox energies the need for increasingly powerful and flexible data management systems. To achieve efficiency and a great level of productivity out of large and complex datasets, operators need have tools that streamline the tasks of managing...

...reaches maturity. Although this model has been well-accepted and the basic empirical finding holds true across a range of industries, we propose that the finding is not as robust as is generally assumed. We introduce an alternative pattern of evolution in which, during the emergent stage, an industry experiences a sharp decrease in the number of firms – a “mini shakeout” – before increasing again, reaching a final peak and undergoing a major shakeout as described in the extant literature. Using panel data across multiple product innovations introduced in the 20th century, we first show the pervasiveness of the mini shakeout phenomena. We then examine why some industries are more likely to experience a mini shakeout. Finally, using detailed quantitative and qualitative data on the emergence of handheld computers and digital cameras, we investigate why some firms abandon...

Consequently, inflation reflects a reduction in the purchasing power per unit of money – a loss of real value in the medium of exchange and unit of account within the economy.[2][3] A chief measure of price...
