PhD Seminar • Algorithms and Complexity • Cheeger Inequalities for Vertex Expansion and Reweighted Eigenvalues

Please note: This PhD seminar will take place in DC 2310.

Kam Chuen (Alex) Tung, PhD candidate
David R. Cheriton School of Computer Science

Supervisor: Professor Lap Chi Lau

The classical Cheeger’s inequality relates the edge conductance of a graph and the second smallest eigenvalue of the Laplacian matrix. Recently, Olesker-Taylor and Zanetti discovered a Cheeger-type inequality connecting the vertex expansion of a graph and the maximum reweighted second smallest eigenvalue of the Laplacian matrix.

PhD Defence • Data Systems • Memory Power Consumption in Main-Memory Database Systems

Please note: This PhD defence will take place online.

Alexey Karyakin, PhD candidate
David R. Cheriton School of Computer Science

Supervisor: Professor Ken Salem

In main-memory database systems, memory can consume a substantial amount of power, comparable to that of the processors. However, existing memory power-saving mechanisms are much less effective than processor power management. Unless the system is almost idle, memory power consumption will be high.
