ABSTRACT: A model is developed to minimize the sum of road construction plus forwarding costs with the constraint that rut depth caused by the forwarder cannot exceed a maximum depth during the anticipated season of operation. Road spacing, forwarder trail spacing, and forwarder capacity are used as decision variables in developing the transportation plan. The total cost was minimized using the...

current study was initiated to generate the information on the effect of row-to-row distance of brassica crop, brassica napus l., on aphids population. three line spacing (20, 30 and 40 cm) with a constant nine cm plant to plant distance were evaluated on aphids infestation and its impact on seed yield. the collected and edited data on fixed parameters indicated that an inverse relation was fou...

a field experiment was conducted to assess the optimum inter- and intra-row spacing on growth, yield and yield component of roselle (hibiscus sabdariffa l.) in 2014/15 cropping season at wondo genet agricultural research center experimental site (at wondo genet station). two inter-row spacing (60 and 90 cm) and three intra-row spacing (30, 60 and 90 cm) were evaluated using two varieties, wg-hi...

The thermal effect of cool jets issuing into an incompressible hot cross flow at an angle over a turbine blade is the subject. Numerical solutions for twelve multiple flow arrangements with two flow ratios, two different hole spacing and four different jet issuing angles document strong to moderate secondary vortex structures spanning normal to the direction of the jet. This fully three-dimensi...

Dense Wavelength Division Multiplexing (DWDM) system is limited by different impairments like optical attenuation, crosstalk, chromatic dispersion, polarization mode dispersion, Scattering etc. All of these impairments restrict the transmission distance and bandwidth. In the Present Scenario the DWDM system needs significant improvement, where analyzing the crosstalk of an Acousto-Optic Tunable...
