MS-DOS for IBM PCs
Published in Paul W. Ross, The Handbook of Software for Engineers and Scientists, 2018
The REN (rename) command changes the name of a file to a new name. The command format for REN is as follows: REN [d:][subdirectory]filename[.ext] filename[.ext] You need to specify the disk drive and subdirectory only for the first file name. If no drive or subdirectory is specified, then MS-DOS will default to the current directory and subdirectory. The second file name will use the drive and subdirectory specified for the first file name. The wildcard characters * and ? may be used in the file name and extension.

In this section, resource management approaches in fog and cloud computing, including single-objective and multi-objective, are examined. The purpose of reviewing these studies is to highlight the importance of using multi-objective approaches versus single-objective approaches. In the problem of services placement, the decision maker is usually interested in multi-objective problem optimization (Skarlat et al. 2017). However, many studies use single-objective models to solve this problem (Lee, Saad, and Bennis 2019; Ren et al. 2019). In general, the importance of optimal resource management and service provision in fog and cloud computing is understood by the research society. Unlike the cloud, research in fog is still immature (Ren et al. 2019). Currently, the focus of resource management researchers on fog computing has been to reduce costs or latencies (Ren et al. 2019). In addition, objectives such as improving QoS, minimizing energy consumption, maximizing the utilization of network resources, improving response time, and minimizing transfer to cloud have also been considered by researchers (Ren et al. 2019).

Then, He, Zhang, Ren, and Sun (2015) proposed a new method, spatial pyramid pooling (SPP-net) to avoid repeatedly computing the convolutional features. This makes it much faster than R-CNN method. Then Girshick (2015) improved their method, proposed a Fast Region-based Convolutional Network (Fast-R-CNN). This method uses Region of Interest (RoI) pooling layer and makes the Fast-R-CNN 3 times faster than SPP-net. Ren, He, Girshick, and Sun (2017) further improved this method, introduced a Region Proposal Network (RPN) to Fast-R-CNN. RPN can predict object bounds at each position, and the convolutional features of RPN is shared with the entire object detection network. RPN can provide region proposals nearly cost-free. This method is called Faster-R-CNN and finally achieves real-time object detection. This paper takes Faster-R-CNN as the object detection method. The structure of Faster-R-CNN used in this study can be seen in Figure 5 below. The structure and roles of each part of Faster-R-CNN can be found in the above-mentioned literature. The output of the Faster-R-CNN on the construction site image is shown in Figure 6, containing the location (in pixel) and categories.
Energy management and stability analysis of the inhomogeneous viscoelastic doubly-curved system via efficient 3D poroelasticity approach
Published in Waves in Random and Complex Media, 2022
One of the most fundamental high-demanded structures in engineering is cylindrical panels [1]. They can be used in order transferring fluids [2] and heat [3], bearing the mechanical stresses [4], etc. Therefore, the material of which these structures are made should be chosen meticulously to be suited for such state-of-the-art applications as spacecraft [5], drug delivery devices [6], automotive industry [7], and so on. Composite materials are founded due to the limitations of isotropic materials. Macro-scale reinforcements placed in a specific angle, as well as a matrix, constitute the early composites [8]. The static response of laminated shells, which was used as a roof in modeled using the classical shell theory (CT), was studied by Ren [9]. The mentioned material can be used in many systems [10–13], and structures [14–17].
