Through this rebinning process, TOF PET data may be converted to any of the following reduced representations: 2D TOF PET data, 3D non-TOF PET data, and 2D non-TOF PET data. Mappings may be exact or approximate. Approximate mappings may not require a Fourier transform in the axial ...
Exact and approximate numerical solutions to steady-state single-server queues:M/G/1 — a unified approach This paper presents a unified approach for the numerical solutions of an M/G /1 queue. On the assumption that the service-time distribution has a rational ... ML Chaudhry,UC Gupta,M ...

This problem was known to have an exact polynomial time solution when δ is below a specific small constant, and hard to approximate within a factor of δ1 -- ε, when δ is polynomially large. Let D be the largest adjacent pair distance, a value potentially much smaller than Δ. Then ...

Mitchell [2000] presents a broad survey of approximate algorithms for graph and geodesic search. Kimmel and Sethian [1998] employ a variant of the fast- marching method to compute approximate geodesics on meshes in O(n log n) time. Several methods [Novotni and Klein 2002; Kir- sanov 2004...
The time complexity of this algorithm is a function of the size of the largest bi-connected component of the graph, of the shortest path distance distribution in this component and of the value of the hyperbolicity. In the worst case, the time complexity remains in O(n^4), but it is ...
