Computing frameworks have been widely deployed to support global-scale services. A job typically has multiple sequential stages, where each stage is further divided into multiple parallel tasks. We call the set of all the tasks in a stage of a job a cotask. In this paper, we aim to minimize the average Cotask Completion Time (CCT) in cotask scheduling. To the best of our knowledge, there is no prior...
A new computational method of computational fluid dynamics (CFD) coupled with rigid body dynamics (RBD) and flight control system (FCS) is developed. In simulations of FCS, the robust and simpler fuzz control method is used instead of the usual PID method. Taking the control of pitching attitude as an example, virtual flight simulations of the basic finner projectile are presented. Simulation results...
IP Fast Reroute (IP FRR) is the IETF standard for providing fast reaction to failures in IP and MPLS/LDP networks. In the past decade, several IP FRR proposals have been proposed, and among them Loop-Free Alternates (LFA) is the simplest, but it cannot achieve 100% single failure coverage. In contrast, Maximally Redundant Trees (MRT) can provide 100% single failure coverage and seems a promising scheme...
This paper presents a hierarchical intelligent control system (HICS) based on soft-sensing of burn-through point (BTP) and vertical sintering speed (VSS) for the sintering process, which has a two-level hierarchical configuration (intelligent control level and basic automation level), and is being used in an iron and steel plant. At the intelligent control level, first, BTP and VSS soft-sensing models...
The debut of the Cloud Computing generation has made information security managing a most significant and critical issue. However, the successful management of information security in cloud computing requires certain factors. This study aims to collect Key Success Factors (KSFs) that determine the management information security in cloud computing through literature review and design of a questionnaire...
Here we examine the partial regularity of minimums of a Laplace functional with the Weber TV image restoration in Bounded Variation space. Most conventional image processors consider little the influence of human vision psychology. This paper proposed a new functional. Furthermore, this functional is not only to use Laplace operator but also to add the human psychology system. Of course, because we...
This paper presents a predictive control strategy named as generalized predictive control with closed-loop model identification for burn-through point (BTP) in sintering process. The closed-loop model identification method describes the dynamic characteristics of sintering process. Based on the model, the BTP generalized predictive control model predicts BTP accurately and computes the strand velocity...
As the deep development of spatial information sharing service, it brings forward high request to usability and expansibility of supporting system. Based on large-scale scalable server cluster, cloud computing brings hopes to resolves the existing difficult problems in the domain of geospatial information service. In this paper, we imported cloud computing technology including MapReduce model and...
An image edge detection method of river regime is presented for river model images. This method of self-adaptive thresholding Canny edge detection can extracts the edges of river regime automatically. It not only inherits the advantages of traditional Canny Algorithm, but also uses the improved maximum variance ratio method to calculate the values of Canny gradient threshold self-adaptively. And on...
At the age of post-Kyoto Protocol, international forestry carbon sequestration project not only has strongly achieved the form of harmoniously developing between economy and environment conservancy in developing countries, but also is promoting the relative research on theory and technology in Forestry Carbon Sequestration. And this paper has discussed that how to establish the Geo-Spatial Model of...
When planning survivable WDM mesh networks, conventional solutions to provide differentiated reliability under shared risk link group (SRLG) constraints mostly assume explicit knowledge of traffic matrices, and consider the failure probability of a fiber link with single criteria (e.g., the link length). Due to the highly variation of nowadays demand patterns and multiple causes of SRLG failures,...
Digital forensics has lately become one of the very important applications to identify the characteristics and the originality of the digital devices. This study has focused on analyzing the relationship between digital cameras and the images. In conjunction with image processing techniques and data exploration methods, it calculates the characteristic values of the images taken by different cameras...
Augmented Reality (AR) is a technology that allows overlaying the computer-generated virtual information into the userpsilas view of the real world, and with changes of his position and line of sight, the virtual objects will change accordingly. AR has many potential applications in industrial operations and academic research. First, this paper discusses the development of 3D visualization of crystal...
This paper presents a design approach for an asymmetrical lambda/2 resonators bandpass filter by using the artificial neural network (ANN) modeling technique. Three important dimensions of the filter layout are used to capture critical input-output relationships in the ANN model. Once fully developed, the ANN model has been shown to be as accurate as an EM simulator and much more efficient computationally...
