TL;DR: In this paper, a method and a device for upgrading virtual machines is presented, where free storage space is reserved in a basic mirror image file corresponding to the virtual machine template to establish a super management virtual machine for the VM template.
Abstract: The invention discloses a method and a device for upgrading virtual machines. The method includes that when each virtual machine template is generated, free storage space is reserved in a basic mirror image file corresponding to the virtual machine template to establish a super management virtual machine for the virtual machine template; when any one virtual machine in the virtual machines which are established on the basis of the basic mirror image file is required to be upgraded, the basic mirror image file corresponding to the virtual machine is looked up, all the virtual machines which are established on the basis of the basic mirror image file are suspended, the basic mirror image file is upgraded through the super management virtual machine corresponding to the basic mirror image file, data changed during upgrading are written into the free storage space reserved in the basic mirror image file, and all the virtual machines which are established on the basis of the basic mirror image file are upgraded in a batch mode. By means of the method and the device for upgrading the virtual machines, when a large quantity of the virtual machines are required to be upgraded, upgrading work loads can be greatly reduced, upgrading operation is simplified, and efficiencies are improved.

TL;DR: In this article, a method and system for presentation of image files in a themed slide show on the graphical user interface is presented, where the selected theme is applied to the set of selected digital image files then creates the slide show.
Abstract: A method and system for execution in a graphical user interface environment are provided. The method and system are used to facilitate presentation of image files in a themed slide show on the graphical user interface. A set of digital image files for possible inclusion in the themed slide show are presented on the graphical user interface. Thereafter, monitoring takes place to check for receipt of an indication that at least a portion of the set of digital image files are to be included in the themed slide show. A number of different themes, each having predetermined theme properties, is presented on the graphical user interface for selection. The themes may include selected corresponding audio files. The selected theme is applied to the set of selected digital image files. Applying the selected theme properties to the set of digital image files then creates the slide show.

TL;DR: In this paper, a capture and replay system identifies images displayed during an application session and uses the uploaded image files to replay the application session to capture application sessions more efficiently by reproducing images from the resource file instead of capturing the images during the original application session.
Abstract: A capture and replay system identifies images displayed during an application session. A parser may generate Hypertext Markup Language (HTML) code from an application resource file or from the JSON post made by the application. A replay engine may use the HTML code to recreate at least some of the screens displayed during the application session. The capture and replay system may dynamically identify images that are not reproduced from the resources database and request an agent/(s) to asynchronously upload the image files associated with the images. The replay engine may use the uploaded image files to replay the application session. The capture and replay system may capture application sessions more efficiently by reproducing images from the resource file instead of capturing the images during the original application session and by dynamically requesting image files for the images were are not previously reproduced from the resource file. Once an image file is uploaded to server, it does not need to be requested again from any other agent.

TL;DR: The proposed method treats a file frag­ment as a grayscale image, and uses image classification method to classify file fragment and two models based on file-unbiased and type- unbiased are proposed to verify the validity of the proposed method.
Abstract: File fragment classification is an important and difficult problem in digital forensics. Previous works in this area mainly relied on specific byte sequences in file headers and footers, or statistical analysis and machine learning algorithms on data from the middle of the file. This paper introduces a new approach to classify file fragment based on grayscale image. The proposed method treats a file frag­ment as a grayscale image, and uses image classification method to classify file fragment. Furthermore, two models based on file-unbiased and type-unbiased are proposed to verify the validity of the proposed method. Compared with previous works, the experimental results are promising. An average classification accuracy of 39.7% in file-unbiased model and 54.7% in type-unbiased model are achieved on 29 file types.
