We report the results of fifteen sets of portfolio selection simulations using stocks in the ASX200 index for the period May 2000 to December 2013. We investigated five portfolio selection methods, random selection, selection within industrial groups, and three based on neighbor-Net phylogenetic networks. We report that using random, industrial groups, or neighbor-Net phylogenetic networks alon...

Tracer chloride and potassium net efflux from valinomycin-treated human erythrocytes were measured into media of different chloride concentrations, Clo, at 25 degrees C and pH 7.8. Net efflux was maximal [45-50 mmol (kg cell solids)-1 min-1] at Clo = 0. It decreased hyperbolically with increasing Clo to 14-16 mmol (kg cell solids)-1 min-1. Half-maximal inhibition occurred at Clo = 3 mM. In the ...

Effective scheduling of hybrid system in industry has a high economic return. However, a hybrid system contains continuous dynamics and discrete dynamics so that the modeling and scheduling of hybrid system become more and more complex and difficult. This paper presented a new approach integrating decomposition of timed hybrid Petri net (THPN) and multi-core cluster to scheduled hybrid system. ...

Consider first the problem of an individual infinitely lived consumer indexed by i who has some predetermined set of expectations for how the aggregate net interest rate rt and wage rate Wt will evolve. At date t household i owns some capital kt,i, and can in principle also borrow; designate the net debt of household i in period t as dt,i; since we will be examining a perfect foresight solution...

This paper analyses the relationship between net farm incomes and market values of cane land within the South African sugar industry. A comparison is drawn between market values represented by actual sales, and productive land values, which relate more specifically to net farm incomes. The aim of the paper is therefore to estimate the degree of correlation between net farm incomes and land mark...

Consumption of fuel oil is increasing, but it is not accompanied by supply. Transportation sector is spent the most existing fuel. Therefore, it is crucial to look for alternative type of fuel such as biodiesel to overcome the fuel shortage. The purpose of this study is to investigate the feasibility on how the investment of waste cooking oil as the biodiesel material production. This study con...
