In analyzing a signal, especially a non-stationary signal, it is often necessary the desired signal to be segmented into small epochs. Segmentation can be performed by splitting the signal at time instances where signal amplitude or frequency change. In this paper, the signal is initially decomposed into signals with different frequency bands using wavelet transform. Then, fractal dimension of ...

I n this study, the Regional Input- Output Structural Decomposition Analysis (I-O SDA) is used to investigate the effects of technological changes on employment in Sistan and Baluchestan Province of Iran during 2006-2011. This paper develops the SDA method to decompose the technological change from two viewpoints of supply and demand for intermediate inputs in each sector. These chan...

In recent years, multi-agent reinforcement learning (MARL) has presented impressive performance in various applications. However, physical limitations, budget restrictions, and many other factors usually impose constraints on a system (MAS), which cannot be handled by traditional MARL frameworks. Specifically, this paper focuses constrained MASes where agents work cooperatively to maximize the ...

In recent years, several robots have been developed and deployed to perform casualty extraction tasks. However, the majority of these are overly complex, require teleoperation via either a skilled operator or specialised device, often must be present at scene navigate safely around casualty. Instead, improving autonomy such can reduce reliance on expert operators potentially unstable communicat...
