Designing optimal teams of sensors to detect the enemy radars for military operations is a challenging design problem. Many applications require the need to manage sensor resources. There is a tradeoff between the need to decrease the cost and to increase the capabilities of a sensor suite. In this paper, we address this design problem using genetic algorithms. We attempt to evolve the characte...

It is manifest the growing interest in both personal health and environmental issues. The device described on this paper contemplates both aspects: generating environment-friendly electric power while keeping fit. A car alternator excited through a 12V battery is coupled to a mountain bicycle, and this arrangement enables the lighting of six halogen lamps, if a cyclist pedals fast enough. Such ...

Pseudomonas aeruginosa is a ubiquitous Gram-negative bacterium having a versatile metabolic potential and great ecological and clinical significance. The geographical distribution of P. aeruginosahas revealed the existence of an unbiased genetic arrangement in terrestrial isolates. In contrast, there are very few reports about P. aeruginosa strains from marine environments. The present work was...

Chinese government is facing the “capital bottleneck” problem for developing urban environmental infrastructure including sewerage treatment and MWS disposal services to achieve the environmental targets set for the 10 Five Year Plan. The solution is worked out as introducing the private investment. This study argue that Public Private Partnership (PPP) is the best available solution for develo...

Materials and methods: Two hundred and fifty-six growing pigs (Yorkshire × Hampshire or purebred Duroc barrows and gilts, initial body weight 34.7 ± 0.5 kg) were used in a randomized block design with a 2 × 2 × 2 factorial arrangement of treatments to determine effects on hematologic and behavioral measures of environmental temperature (constant-thermoneutral at 24 ̊C or cycling-high from 28 ̊C t...

Twelve- and 18-month-old infants participated in a study designed to investigate the quality of their manual action when relating an object to the surface on which it is explored. Specifically, infants' perception-action routines were observed when they were presented with multiple objects (wooden scoop, Velcro block, and crayon) on surfaces of varying properties (paper, sand, and Velcro) to de...

In this work, approximate formulas are presented for computing the magnetic field intensity near electric power transmission lines. Original expressions are given for single circuit lines of any type of arrangement and double circuit lines in both super-bundle and low-reactance conductor phasing. These expressions can be used for assessing directly the Right-of-Way width of power lines related ...

A natural uranium silicate mineral, cuprosklodowskite, has been analyzed by Resonance Ionization Mass Spectrometry (RIMS) for uranium isotope composition under a variety of experimental conditions. While no significant isobaric interferences are observed in the mass regions of interest, molecular supression is incomplete, and varies with the method of neutral U atom production. Despite low meas...

Intracellular substances released into the medium during rehydration of dry yeast cells can significantly improve the quality of a synthetic medium. Acceleration of yeast growth in this medium and increased yield of biomass are observed simultaneously. The change in the molecular arrangement of intracellular membranes as a result of the strong dehydration of live organisms is a negative phenome...
