The mounting increase in the technological complexity of modern engineering systems requires compound uncertainty quantification, from a quantitative and qualitative perspective. This paper presents Compound Uncertainty Quantification Aggregation (CUQA) framework to determine outputs along with determination greatest contribution via global sensitivity analysis. was validated two case studies: ...

With mounting global network connectivity, the issue of intrusion has achieved importance, promoting active research on efficient Intrusion Detection Systems (IDS). Artificial Immune System (AIS) is a new bio-inspired model which is applied for solving various problems in the field of information security. Because of its unique features, (self-learning, self-adaptation and selfimprovement), AIS...

Machine learning is used in this study to deal with the reduction design period and major performance improvement of selective catalyst system. The system helps NOx emission diesel engine. existing methods for systems tend be inefficient, due layout changes that require modification when mounting a vehicle based on previously designed models. There are some factors can affect engine identified ...

In this paper, effect of geometric parameters of a centrifugal fan with backwardand forward-curved blades has been investigated. Centrifugal fans are used for enhancing the heat dissipation from the IC engine surfaces. In the process, the fan consumes power generated from the engine. As a first step, an experimental setup was developed and prototypes of fans were made to carry out measurements ...

In recent years, commercial demand for comfortable and quiet vehicles has encouraged the industrial development of methods to accommodate a balance of performance, efficiency, and comfort levels in new automotive year models. Particularly, the noise, vibration and harshness characteristics of cars and trucks are becoming increasingly important (see, e.g., (Buchholz, 2000), (Capitani et al., 200...

in this study, a numerical simulation using the cfd software, fluent, has been conducted to examine the effect of various shapes of the venturi component sections in order to find the optimum venturi specifications to increase the egr rate with minimum pressure loss at the part load operation range. the cfd results reveal that the venturi should be precisely optimized to introduce the required ...

Compressors are a primary cause for numerous HV AC noise and vibration problems. Typically, vibration energy is transmitted from the compressor to the chassis through piping and isolation mounts. The design of these attachments is thus of paramount importance in determining the dynamic performance of a HV AC unit. Below certain frequencies, compressor vibration can be well described as a rigid-...
