Multipliers are used in all modern digital systems and DSP applications. They are used in hardware multiplication to achieve high data throughput. Multipliers are major sources of area consumption and power dissipation in such systems. Reduction in area can be achieved using Booth encoding and Wallace tree technique since they generate partial products efficiently and are most suited for multip...

Normal meshes were recently introduced as a new way to represent geometry. A normal mesh is a multiresolution representation which has the property that all details lie in a known normal direction and hence the mesh depends only on a single scalar per vertex. Such meshes are ideally suited for progressive compression. We demonstrate such a compression algorithm for normal meshes representing co...

I describe the customer valuations game, a simple intuitive game that can serve as a foundation for teaching revenue management. The game requires little or no preparation, props or software, takes around two hours (and hence can be finished in one session), and illustrates the formation of classical (airline and hotel) revenue management mechanisms such as advanced purchase discounts, booking ...

We use an all-optical trap to confine a strongly attractive two-state mixture of lithium fermions. By measuring the rate of evaporation from the trap, we determine the effective elastic scattering cross section 4pia(2) to show that the magnitude of the scattering length |a| is very large, in agreement with predictions. We show that the mixture is stable against inelastic decay provided that a s...

When controlling Takagi-Sugeno fuzzy systems, verification of some sector conditions is usually assumed. However, setpoint changes may alter the sector bounds. Alternatively, setpoint changes may be considered as an offset addition in many cases, and hence affine Takagi-Sugeno models may be better suited to this problem. This work discusses a nonconstant change of variable in order to carry out...

The choice of a particle size analyzer has never been more difficult. There are several techniques from which to choose and variations within each technique. Sales literature claims of specification and performance have become highly inflated, confusing the first-time buyer; the result has been to hinder and not help the decision making process. Many particle sizing instruments were originally ...

The characteristic difference between laws and accidental generalizations lies in our epistemic or inductive attitude towards them. This idea has taken various forms and dominated the discussion about lawlikeness in the last decades. Hence, ranking theory with its resources of formalizing defeasible reasoning or inductive schemes seems ideally suited to explicate the idea in a formal way. This ...
