What types of systems are used for enterprise wide knowledge management and how do they provide value for businesses?
• Define and describe the various types of enterprise-wide knowledge management systems and explain how they provide value for businesses.
• Describe the role of the following in facilitating knowledge management: portals, wikis, social bookmarking, and learning management systems.
a. Determine the current I(t) required to produce the B-field 2cos(wt)(T) in terms of other variables, for a sinusoidal field of 60 Hz, and N=100 turns. b. Now assume that you have the above B-field generated inside the solenoid.
an ac generator with a frequency of 150hz and an rms voltage of 22.5v is connected in series with a 15.0 kilo ohms
show that the most probable electron energy in the conduction band of a semiconductor is kt2 above the bottom of the
A first-order allpass filter impulse response is given by h(t) = - d(t) + 2e^(-t)*u(t) a) find the zero-state response of this filter for the input e^(t)*u(-t). b) sketch the input and the corresponding zero-state response.
A standard D cell flashlight battery is connected to a load of 3 ohms. After 6 hr of intermittent use the load voltage drops from an initial 1.5 V to a final useful voltage of 0.9 V. (a) Calculate the internal resistance of the battery at the load ..
A point charge of 20 [nC] is located at (4,-1,3), and a uniform line charge of -25[nC/m] lies along the intersection of the planes x=-4 and z=6. (a) Calculate D at (3,-1,0). (b) How much electric flux leaves the surface of a sphere of radius 5, ce..
Design a linear broadside array to have nulls along the directions θ = 50°,130°, and 0° , namely find the number of elements , and the relative currents , find the beamwidth to nulls and the side lobe level .
Prove the same result using the formula inside the back cover for ∇2 in spherical polar coordinates. (Obviously, this second proof is much simpler, but the hard work is hidden in the derivation of the formula for ∇2.)
A system consists of three components in series, each with a reliability of 0.935. A second set of three components is purchased and a redundant system is built.
Find the magnification of a microscope and plot the picture of the rays to scale using the graph paper - Explain in your own words the difference between photoluminescence and electroluminescence.
Determine the electrical power per unit length of the cylinders (W/m) that is required to maintain the outer surface of cylinder B at 5°C.
For the system of given figure: - At first exposure, does the design appear to be a good one? - In the absence of the 10-kΩ load, what are the values of R1 and R2 to establish 3 V across R2?
