Optimization methods based on input impedance target functions have been proposed for the design of brass musical instruments. Criteria for target functions in trombone bore optimization are discussed, drawing on experimental input impedance data from a variety of high-quality trombones of differing sizes. An "inharmonicity plot" is introduced and used to aid the interpretation of impedance cur...

The software TRiP98 [1, 2, 3] is successfully used for patient treatment planning in the GSI pilot project. A crucial part of the treatment planning is the particle number optimization. The main goal of optimization is to achieve a target dose distribution as close as possible to the prescribed biological dose distribution. Multiple field optimization (MFO) allows a better target conformity and...

The weapon target assignment is an important problem in modern air defense combat with multiobjects and fighters. The weapons units arrange is a dynamic and complex process, for saving weapons resources and attacking target effectively, the weapon target assignment model satisfies expected damage probability, the performance analysis such as target threat degree, the weapon attack priority and ...

In radiation therapy planning, uncertainties in target volume definition yield a risk of underdosing the tumor. The classical way to prevent this in the context of external beam radiotherapy (EBRT) has been to expand the clinical target volume (CTV) with an isotropic margin to obtain the planning target volume (PTV). However, the EBRT-based PTV concept is not directly applicable to brachytherap...

In this paper we focus on robust linear optimization problems with uncertainty regions defined by φ-divergences (for example, chi-squared, Hellinger, Kullback-Leibler). We show how uncertainty regions based on φ-divergences arise in a natural way as confidence sets if the uncertain parameters contain elements of a probability vector. Such problems frequently occur in, for example, optimization ...

Recent considerations in semiconductor portability and increasing clock cycle rates require designs that consume little power but meet strict performance requirements. Due to these facts, it becomes apparent that circuit optimization remains an important task in the overall design cycle. Traditionally, logic optimization is carried in two steps. In the first step, technology independent optimiz...

Detecting and tracking ground targets is crucial in military intelligence in battlefield surveillance. Once targets have been detected, the system used can proceed to track them where tracking can be done using Ground Moving Target Indicator (GMTI) type indicators that can observe objects moving in the area of interest. However, when targets move close to each other in formation as a convoy, th...

AbstrAct: This study proposes a non-dominated sorting genetic algorithm-II-based multi-objective optimization method to solve the multi-objective mission planning problem for satellite formation flying system which has the ability to obtain both digital elevation map and ground moving target indicator information at the same time when certain conditions are satisfied. The 2 objectives considere...

Target cascading in product development is a systematic effort to propagate the desired top-level system design targets to appropriate specifications for subsystems and components in a consistent and efficient manner. If analysis models are available to represent the relevant design decisions, analytical target cascading can be formalized as a hierarchical multilevel optimization problem. The a...
