A Tradeoff Between Length and Width in Resolution

Neil Thapen
2016 Theory of Computing  
We describe a family of CNF formulas in n variables, with small initial width, which have polynomial length resolution refutations.  ...  By a result of Ben-Sasson and Wigderson it follows that they must also have narrow resolution refutations, of width O( √ n log n).  ...  Acknowledgements I am grateful to Jakob Nordström for making me aware of this problem, and to Jakob Nordström and Nicola Galesi for helpful comments on an early version of this paper.  ...

the mentioned classical tradeoff between spectral leakage and frequency resolution.  ...  CONCLUSION A window derived from the Butterworth filter does allow a tradeoff between frequency resolution and sidelobe attenuation, but it has no special property to eliminate this tradeoff.  ...

Vertical Resolution of Temperature Profiles Obtained from Remote Radiation Measurements

Barney J. Conrath
1972 Journal of the Atmospheric Sciences  
Thus, there is a tradeoff between vertical resolution and accuracy 9 and the best choice for q must be determined by the particular application.  ...  The resulting relationship is called the "tradeoff curve" and can be used to analyze the tradeoff between vertical resolution and errors in the estimated temperature due to random errors in the measurements  ...

Analysis of resolution for an amplitude-steered array

Catherine H. Frazier, W. Jack Hughes, William D. O'Brien
2000 Journal of the Acoustical Society of America  
The dependence of axial resolution on the length of the array is a unique feature of the amplitude-steered array, leading to an interesting tradeoff between lateral and axial resolution.  ...  For the linear amplitude-steered array, we show that both lateral and axial resolution are limited by the length of the array.  ...  In addition to the resolution tradeoff that arises due to the length of the array, there is an additional tradeoff between axial and lateral resolution due to the processing.  ...

Optimality of size-width tradeoffs for resolution

Maria Luisa Bonet, Nicola Galesi
2001 Computational Complexity  
This is a consequence of our main result: we show the optimality of the general relationship called size-width tradeoff in Ben-Sasson & Wigderson.  ...  This paper is concerned with the complexity of proofs and of searching for proofs in resolution.  ...  Part of this work was done while Nicola Galesi was a member of the School of Mathematics at the Institute for Advanced Study (Princeton) supported by a NSF grant CCR-9987845.  ...

2016 Fisheries Research  
In the context of estimation, there generally was a predictable tradeoff between estimation accuracy and model run time, with finer model and data bins always improving estimation accuracy and model convergence  ...  The effect of choices regarding the number and width of these bins on model output is unclear, and these choices are made inconsistently in assessments across regions and species.  ...  Partial support for this research came from a Eunice Kennedy Schriver National Institute of Child Health and Human Development research infrastructure grant, R24HD042828, to the Center for Studies in Demography  ...

Interconnect Bundle Sizing Under Discrete Design Rules

Konstantin Moiseev, Avinoam Kolodny, Shmuel Wimer
2010 IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems  
We present a dynamic programming (DP) algorithm for simultaneous sizing and spacing of all wires in interconnect bundles, yielding the optimal power-delay tradeoff curve.  ...  The lithography used for 32 nanometers and smaller VLSI process technologies restricts the admissible interconnect widths and spaces to a small set of discrete values with some interdependencies, so that  ...  ACKNOWLEDGEMENT The authors would like to express their deep gratitude for the excellent comments and suggestions provided by the reviewers, which enabled significant improvements in the manuscript.  ...

A New Kind of Tradeoffs in Propositional Proof Complexity

Alexander Razborov
2016 Journal of the ACM  
Our construction and proof methods combine, in a non-trivial way, two previously known techniques: the hardness escalation method based on substitution formulas and expansion.  ...  We exhibit an unusually strong tradeoff in propositional proof complexity that significantly deviates from the established pattern of almost all results of this kind.  ...  Acknowledgement I am greatly indebted to Jakob Nordström and the anonymous referee for extensive and very useful comments on an earlier version of this paper.  ...

Enabling EUV Resist Research at the 1x and Smaller Regime

Patrick Naulleau, Christopher Anderson, Weilun Chao, Kenneth Goldberg, Antoine Wojdyla, Suchit Bhattarai, Andrew Neureuther, Frank Goodwin, Mark Neisser
2015 Journal of Photopolymer Science and Technology (Fotoporima Konwakai shi)  
A variety of resists, both chemically amplified and not, have been developed meeting resolution needs, but falling short on sensitivity and line-width roughness (LWR).  ...  Note that resolution is an absolute mandatory requirement, the true tradeoff that must be considered is between sensitivity and contact hole printing is a crucial application for extreme ultraviolet lithography  ...  Noting that resolution is an absolute mandatory requirement for EUV resists and cannot be relaxed, the true tradeoff that must be considered is between sensitivity and LWR.  ...

Characteristics of multiplexing parallel beam (MPB) by using Monte Carlo simulation [article]

Zhao Jing-Wu, Ma Jia-Yi, Shi Xiao-Dong
2013 arXiv   pre-print
However the effective hole length is used in the calculation of the system matrix to correct for the penetration, which has a satisfactory result.  ...  It is discussed that the point spread function (PSF) of multiplexing parallel beam (MPB) is shift-invariant; the spatial resolution is linear as a function of depth h and the geometrical sensitivity is  ...  On the contrary, it suffers from low sensitivity when the resolution is high. Therefore there is tradeoff between the sensitivity and resolution.  ...
