Optimum nonuniform transmultiplexer design [PDF]

open access: yes, 2003
This paper considers an optimum nonuniform FIR transmultiplexer design subject to specifications in the frequency domain. Our objective is to minimize the sum of the ripple energy for all the individual filters, subject to the specifications on amplitude

Elastoplastic deformation analysis by return-mapping and consistent tangent modulus tensor based on subloading surface model (1st Report, Formulation of return-mapping)

open access: yesNihon Kikai Gakkai ronbunshu, 2014
The subloading surface model possesses the automatic controlling function to pull back the stress to the yield surface. However, this function is not concerned with the subyield state, i.e.

Optimum management of inverted papilloma [PDF]

open access: yes, 2002
Surgery offers the optimum modality of treatment for inverted papilloma although a considerable range of operative approaches have been described. The results are presented in a cohort of 37 cases treated by both endoscopic and combined endoscopic and ...

On Optimum End-to-End Distortion in MIMO Systems [PDF]

open access: yes, 2010
This paper presents the joint impact of the numbers of antennas, source-to-channel bandwidth ratio and spatial correlation on the optimum expected end-to-end distortion in an outage-free MIMO system. In particular, based on an analytical expression valid

Optimum wordlength allocation [PDF]

open access: yesProceedings. 10th Annual IEEE Symposium on Field-Programmable Custom Computing Machines, 2003
This paper presents an approach to the wordlength allocation and optimization problem for linear digital signal processing systems implemented in Field-Programmable Gate Arrays. The proposed technique guarantees an optimum set of wordlengths for each internal variable, allowing the user to trade-off implementation area for error at system outputs ...

Theory of optimum shapes in free-surface flows. Part 1. Optimum profile of sprayless planing surface [PDF]

open access: yes, 1972
This paper attempts to determine the optimum profile of a two-dimensional plate that produces the maximum hydrodynamic lift while planing on a water surface, under the condition of no spray formation and no gravitational effect, the latter assumption ...

Selfish Yet Optimal Routing by Adjusting Perceived Traffic Information of Road Networks

open access: yesIEEE Open Journal of Intelligent Transportation Systems, 2020
Traffic congestion in urban areas causes economic and time loss. Such traffic congestion is caused by selfish routing where users aim to minimize their own travel time.
