    Optimizing Productivity: Linear Programming for All-Easy's Production Goals

    yes.. bec. I don't feel that my model is a formal one yet... =)

    Optimizing Productivity: Linear Programming for All-Easy's Production Goals

    Um... I did understand about it... but if I were to write the final part as my model for the LP, it seems that it is "unstable"... bec. I am following the standard form of a LP model...

    Optimizing Productivity: Linear Programming for All-Easy's Production Goals

    I got this idea... so at least, I can show you where am I... got stuck We have a constraint on Labor: 2x + 3y + 5z <= 70, but it can be exceeded ... at extra cost. If 2x + 3y + 5z is greater than 70, it costs an additional $15/hour. The excess is: (2x + 3y + 5z - 70) hours which...

    Optimizing Productivity: Linear Programming for All-Easy's Production Goals

    All-Easy manufactures three products whose unit profits are $1, $9 and $5, respectively. The company has budgeted 70 hrs. of labor time and 45 hours of machine time for the production of three products. The labor requirements per unit of products A,B C are 2, 3 and 5 hours, respectively. The...

    Does the pilot's claim credible?

    Is it possible that the claim of the pilot is true that he can sue the Earth's field to navigate in air in a plane without engines? He will induce a charge in the body of the plane, so that a force of magnetic origin is exerted on the plane, because the charge that is moving in a magnetic...

    What Are the Health Effects of Living Near Power Lines?

    I want to ask about the applications of magnets Is it possible that people who lived in a town could have health problems such as headaches, nausea, brain tumors.. due to an established plant, which distributes power to nearby towns and cities through hundreds of high-tension cables...

    Exploring Magnetic Induction: Horseshoe Magnets & Line Formation

    hello.. yups.. about lines of induction... just to see how "fields" look like

    Exploring Magnetic Induction: Horseshoe Magnets & Line Formation

    Sirus, the two horseshoe magnets are placed close to each other without contact such that (1) like poles are aside and (2) when unlike poles are aside...

    Exploring Magnetic Induction: Horseshoe Magnets & Line Formation

    how are lines of induction formed due to 2 horseshoe magnets that are placed side by side but no contact? Are there websites that would show me about it?

    Possible that a fabric can be used as a diffraction grating

    One more thing... How is it possible for those "sound waves" be heard by a person even if he's in a different house... I mean, yup, by diffraction, one can hear your neighbor shouting at your house? How would that sound travel.. in order to hear it?

    Possible that a fabric can be used as a diffraction grating

    Is it possible that a fabric can be used as a diffraction grating where in the space between strands of threads is a small fraction of a millimeter? My answer is yes. does it mean that the light can be bended due to this? I mean how come?

    Optics Diffraction Problems: Finding Maximum Intensity Angles and Slit Widths

    Specifically, diffraction.. here are the insights of the problems... 1. For a radio station operating at a frequency of 103.3 MHz has two identical dipole antennae 1000m apart, transmitting in a phase. At distances much greater than 1000m, at what angles is the intensity at a maximum...

    A proving on random variables

    Sir matt grime/anyone... =] I hope someone can guide me. I want to prove first the continuous. So, the joint pdf can be described as f[g(X),h(Y)] = INTaINTb g(x)h(y) dx dy -> am I right here? where a and b are arbitrary intervals. = INTa h(y) [INTb...
