The favorable reception of Portfolio Management Formulas exceeded even the greatest expectation I ever had for the book. I had written it to
promote the concept of optimal f and begin to immerse readers in portfolio theory and its missing relationship with optimal f.
Besides finding friends out there, Portfolio Management Formulas was surprisingly met by quite an appetite for the math concerning money
management. Hence this book. I am indebted to Karl Weber, Wendy Grau, and others at John Wiley & Sons who allowed me the necessary latitude
this book required....
An empirical formula representing the variation of the . quantity with mole
fraction of acetonitrile (/) from the values in Table 4-4 could be determined
using equation (4-20). The dependence of . versus the mole fraction of ace-
tonitrile is shown in Figure 4-25.
Standard Practice for classification of soils and soil-aggregate mixtures for highway construction purposes practice covers a procedure for classifying mineral and organomineral soils into seven groups based on laboratory determination of particle-size distribution, liquid limit, an plasticity index. It may be used when precise engineering classification is required, especially for highway construction purposes. Evaluation of soils within each group is made bymeans of a group index, which is a value calculated from an empirical formula.
This is a medical detective story: beginning with the investigation of
a disease that has killed or crippled at least a million people, and then
following up clues that ranged much wider. One outcome was the
production of a synthetic chemical that we now, nearly all of us, consume
in small quantities each day in our food. The detectives had a
variety of professions and spoke different languages.
In the range of high strain rates, the mechanical behaviour of materials is characterized by an increased
strain rate sensitivity, by increasing effects of mass inertia forces and by the adiabatic character of the
For the relation between stress, strain and strain rate, empirical formulae are now mostly replaced by
material laws based on structural mechanical models, whose parameters are to be determined by adequate
systematic methods. Also special effects such as the influence of strain rate on...
