In this paper, we present a variant of Diem’s Õ(q) index calculus algorithm to attack the discrete logarithm problem (DLP) in Jacobians of genus 3 non-hyperelliptic curves over a finite field Fq. We implement this new variant in C++ and study the complexity in both theory and practice, making the logarithmic factors and constants hidden in the Õ-notation precise. Our variant improves the comput...

determination of trade-off, which they are feasible and similar variations on all of decision making units (dmu), is important issue in data envelopment analysis (dea). in this paper, we select these trade-offs based on an external evaluation of dmus such that the correlation between external evaluation and technical evaluation resulted from dea model is maximized. in fact, we sift the trade-of...

Lane et al. propose an integrative model for the reconsolidation of traces in their timely and impressive article. This commentary draws attention to trade-offs between accuracy and self-narrative integrity in the model. The trade-offs concern the sense of agency in memory and its role in both implicit and explicit memory reconsolidation, rather than balances concerning degrees of emotional aro...

Spin-tronic memory is a promising technology and offers advantages due to its nonvolatility and higher density. At the same time, based on device properties, there are trade-offs that decide the energy and performance penalty overhead. To decide these trade-offs its it imperative to understand the sensitivity of different parameters in the memory subsystem. In this work, we use a known statisti...

As the coronavirus disease 2019 (COVID-19) pandemic continues to unfold there is an untold number of trade-offs being made in every country around the globe. The experience in the United Kingdom and Canada to date has not seen much uptake of health economics methods. We provide some thoughts on how this could take place, specifically in three areas. Firstly, this can involve understanding the i...

Stream ciphers are an important class of symmetric cryptographic algorithms. The eSTREAM project contributed significantly to the recent increase of activity in this field. In this paper, we present a survey of the eSTREAM project. We also review recent time/memory/data and time/memory/key trade-offs relevant for the generic attacks on stream ciphers. c © 2010 ISC.

T he parallel processing issue must be addressed on three levels: (1) Architectural issues include how to organize and implement computers that have multiple processing elements. (2) Software issues include applications and sys tem software. (3) Algorithm issues involve how io design parallel algorithms. l Architects of parallel-processing s y s tems struggle with important trade-offs. Their ch...

A memory power optimization and performance exploration methodology based on high-level (C language) code transformations that allows the system designer to explore various data memory power, data memory area and performance trade-offs early in the design process of embedded multimedia systems is introduced. This exploration strategy is introduced for both single and multiprocessor environments...

Energy-efficient scheduling is an effective way to balance the system performance and the energy consumption. We design a polynomialtime (1 + )-approximation algorithm to minimize the energy consumption for periodic real-time tasks over such processors, where is the tolerable error given by users (1 ≥ > 0). It provides trade-offs between the user’s tolerable error and the runtime complexity inc...
