Structural noise is an important factor that endangers aircraft fatigue life and flight safety. It also has a negative effect on aircraft stealth performance and noise navigability. An optimal design of a structure-acoustic coupled system is an effective way to reduce noise and vibration. Due to the uncertainties that exist in the structural and acoustical parameters, the traditional determinis...

seismic inversion is a method that extracts acoustic impedance data from the seismic traces. sourcewavelets are band-limited, and thus seismic traces do not contain low and high frequency information.therefore, there is a serious problem when the deterministic seismic inversion is applied to real dataand the result of deterministic inversion is smooth. low frequency component is obtained from w...

This paper examines the feedback design possibilities for uncertain plants where the underlying parameterisation is described by a probabilistic rather than a deterministic set membership. The design perspective is Horowitz' quantitative feedback theory.

Interleaver design plays an important role to improve the performance of turbo codes. The optimal performance can be obtained by using pseudo-random interleaver design. However, it is difficult to analyze the corresponding pseudorandom algorithms such that the performance can be guranteed, and furthermore they are computational expensive. In this paper, we focus on deterministic turbo codes int...

The emphasis on human experience and experience in the Design Research literature is growing along with the importance of human-centered approaches to design. However, the fundamental connection between emotions and experience is not well understood mostly due to the lack of research in the nature of human experience in the design research literature. Many approaches tend to determine the “rule...

Topology optimization often incorporates a reliability analysis to take the randomness in the design parameters into account. This strategy is inherently a double-loop procedure due to the probabilistic constraints in optimization. To simplify the calculation procedure, an equivalent-deterministic constraint, which is constructed by adding a penalty on the right hand side (RHS) of a limit state...

In recent days the expectations of wireless communication systems have to configure new technologies that support high capacity to match the increase in demands on wireless service. A new hybrid scheme namely Orthogonal Frequency Division Multiplexing Interleave division Multiple Access (OFDM-IDMA) is a hopeful candidate of future wireless communication systems. In OFDM-IDMA the users are separ...

The objective of this paper is to give a survey on the use of non-probabilistic methods for non-deterministic numerical analysis. It consists of a general theoretical discussion on the use of non-deterministic concepts in numerical analysis, an overview of the basic properties of possible implementations of the non-probabilistic finite element code, and finally a discussion on their possible ap...

In contrast to the vast amount of literature in random matrices in the field of compressed sensing, the subject of deterministic matrix design is at its early stages. Since these deterministic matrices are usually constructed using the polynomials in finite Galois fields, the number of rows (number of samples) is restricted to some specific integers such as prime powers. In this paper, besides ...

Aeroelastic flutter is a dangerous failure mode, and aircraft structural components are designed under a deterministic flutter margin. Meeting this safety factor may result in overly-conservative structures, however, an alternative approach incorporates uncertainties into the computational models, and imposes a maximum allowable flutter probability during the optimization process. This techniqu...
