Lecture 22 — November 19 , 2015
In terms of exact numbers, hard drives support somewhere around 140MB/sec of sequential reads/writes, but only 120I/O’s/sec when doing reads/writes on random 4KB chunks. This is because the disk must physically spin to the read/write location. RAM supports somewhere around 5-10GB/sec of reads/writes, with much less penalty for random access. SSDs/Flash is somewhere in the middle, but with the i...

Previously, we looked at basis pursuit and iterative hard thresholding (IHT) for `2/`1 sparse signal recovery. Recall that from before the `2/`1 guarantee: time per iteration depends on matrix-vector multiplication time by Π,ΠT in the IHT algorithm. To make this fact, the only way we know is to use a fast such Π, such as sampling rows from the Fourier matrix. However, for those Π we do not know...

φ ≡ C1 ∧ · · · ∧ Cm , where each Ci is a clause of the form Ci = (li1 ∨ li2 ∨ li3) and each lij is in turn xij or its negation xij . We assume that each clause contains three distinct variables. In the problem Max 3-SAT, the goal is not necessarily to satisfy all the clauses, but rather find an assignment to the variables which satisfies as many clauses as possible. We show that for any formula...

Hand operation accompanied with any combination of large forces, awkward positions and repetition may lead to upper limb injury or illness and may be exacerbated by vibration. Commercial lawn mowers expose operators to these factors during actuation of hand controls and therefore may be a health concern. A nontraditional lawn mower control system may decrease upper limb illnesses and injuries t...
