New Approach to Estimation of the Decoding Error Probability

We suggest a new approach to constructing a lower bound on the decoding error probability in a discrete memoryless channel at zero transmission rate. This approach considerably simplifies derivation of the bound, making it more natural, and simultaneously improves the remainder term of the estimate for the decoding error exponent.     

一种结合边缘检测的模糊估计新方法

传统的图像质量评价方法MSE和PSNR都是基于全参考(FR)的质量评价方法,这就要求在对图像进行质量评价时给出参考图像,因此这种方法在实际应用中并不实用,而无参考(NR)图像质量评价正好解决了这一问题,因此具有重要意义.针对数字图像的客观质量评价,从模糊距离检测角度,提出了一种结合边缘检测的图像模糊估计的无参考图像质量评价方法,对比现有模糊检测方法,此方法比单独的边缘检测方法和模糊估计方法更为有效.经过对结果的分析与比较,本文方法的检测结果与主观感知质量有很好的相关性,而且算法具有复杂性低、无需参考源、检测准确性高、可移植性强等特点,因此实用性比较强.     

一种基于模糊Gibbs随机场的运动估计新算法

运动估计问题具有不适定性，单纯采用最大后验概率算法，实际上并未解决运动矢量的不连续、矢量的失真与随机噪声等棘手问题。本文应用模糊数据融合与Gibbs分布的基本思想，将运动场风险约束条件的概率分布模式有效地纳入阶段非凸函数(GNC)算法的局部迭代过程中，从而提高了运动估计效果。首先建立Gibbs的自适应能量模型，该模型可将基于特征和基于梯度的两类矢量按照优化约束条件进行融合；其次利用各种运动经验知识构造矢量的模糊风险决策表，该决策表可对Gibbs能量方程的每一步迭代收敛结果进行监督和修正，从而实现模糊数据融合。从收敛性和鲁棒性两方面说，模糊融合后的结果在原有基础上有明显提高。     

A New Approach to Estimation of the Effectiveness of Control Decisions under Conditions of Risk in ACS's

A new approach to the decision making in automatic control systems (ACS) under conditions of a risk is suggested, which reduces to the use of a risk function as an equivalent criterion along with the initial one. It is assumed that only the bounds of changes of uncertainties are known, but any statistical characteristics are unavailable. A formalized procedure of making guaranteed decisions is worked up and their existence is proved under constraints that are common in the mathematical theory of games.

A New Approach to Crisis Management

The key to effective crisis management lies not so much with the writing of detailed manuals (that have a low likelihood of being used, and an even lower likelihood of being useful) and practising location evacuations as with structured and continuous learning processes designed to equip key managers with the capabilities, flexibility and confidence to deal with sudden and unexpected problems/events – or shifts in public perception of any such problems/events.     

A New Approach to Primary Decomposition

The first purpose of this paper is to describe a new mathematical approach for the computation of an irredundant primary decomposition of a given polynomial ideal I. This presentation will be formed of three parts: a decomposition of the associated radical ideal I to an intersection of prime ideals P_i, then the determination of ideals I_iwhose radical is prime (equal to P_i), and finally, the extraction of the possible embedded components included in I_i. The second is to give an implementation of this algorithm via a new software component, called The Central Control², in which we implemented distributed algorithms performing the basic operations of algebraic geometry.     

A New Approach to Humanitarian Demining

Humanitarian demining is an application in which the use of tele-operated machines and mechanisms has been gaining acceptance recently. Actually, demining is just one among many other field applications that require a high degree of mobility, manipulation of loads, robustness and, above all, high efficiency in terms of energy consumption. This paper will present the development and analysis of Field Arm, a pantographic manipulator especially designed for field works, focusing on its kinematic, static and dynamic properties. The novel features of Field Arm will be presented and discussed with results of simulations and experiments.

A New Approach to Humanitarian Demining

Landmines can deprive whole areas of valuable resources, and continue to kill and cause injuries years after the end of armed conflicts. Armored vehicles are used for mine clearance, but with limited reliability. The final inspection of minefields is still performed by human deminers exposed to potentially fatal accidents. The aim of this research is to introduce automation as a way to improve the final level of humanitarian demining. This paper addresses mobility and manipulation, while sensing, communication and visualization shall be discussed in detail in a subsequent paper. After analyzing the merits and limitations of previous works, a new approach to tele-operated demining is considered, using off-road buggies equipped with combustion engines, and taking into account actual field requirements. Control of the automated buggies on rough terrain is also discussed, as well as the development of a new weight-balanced manipulator for landmine clearance operations.Paulo Debenest received the B.
