Flexible Job-shop Scheduling Problem;Iterated Greedy;Telescopic Population
摘要:
The flexible job-shop scheduling problem (FJSP) is known as an important problem in manufacturing systems. Many methods have been proposed to solve this problem. The iterated greedy (IG) is one of those algorithms that are widely used in simpler shop scheduling problems. This research proposes a new Telescopic Population approach (TP) to assist the IG in solving the FJSP. The use of TP approach with IG provides an effective method that is also easier to reproduce. The performance of TP with IG proves that the new population approach effectively improves the performance of IG.

摘要:
Extraction of tree crown has always been a research hotspot in forestry remote sensing. With the rapid development of UAV technology, aerial imagery can clearly identify the information of ground forest tree crowns. However, Due to the overlapping of tree crown, how to divide the crown size between trees is still a difficult problem. In this paper, the ecological experiment forest of Central South University of Forestry and Technology was selected as the study area, the UAV image in the visible light band was used as experimental data, and the Pinus massoniana as the object of study, the transect sample algorithm was used to extract the size of the individual forest tree crown in the study area. By analyzing the correlations between R, G, and B bands in the visible light band, several major visible vegetation indices and tree crown information, relevant factors suitable for tree crown extraction were selected. Since the aerial imagery used in this study has an ultra-high resolution, the gaps in the crown width of single wood are clearly visible, which is not conducive to transect sample algorithm to extract the crown width. Therefore, the image is smoothed by setting the window size of the 7*7 pixel to reduce the influence of the crown gap on the transect sample algorithm. In the end, the tree crown was extracted by the transect sample algorithm. The results show that: The green band and the CIVE extraction. The total precision of the extraction of Pinus massoniana by transect sample algorithm is 84.1%, and the method can extract the single crown of partial crown to a certain extent, and it can get better effect for the forest with low canopy density.

摘要:
Non-slip and noise reduction asphalt pavement is a new type of asphalt pavement. As its good resistance to sliding, reducing the noise, inhibiting driving water on a rainy day and reducing the "glare" when drive at night, non-slip and noise reduction asphalt pavement is becoming more and more popular in domestic. This paper mainly analyzes the long term performance of non-slip and noise reduction asphalt pavement in the southern rainy, humid, and hot climates. This pavement has been followed up and observed for one year. The change rules of drainage performance, roughness, noise reduction, anti-sliding performance are concluded, which could provide technical guidance for estimating the engineering application of non-slip and noise reduction asphalt pavement.
摘要:
PolInSAR data consist of two SAR images, and the spatial baseline, incident angle, slanting distance, wavelength of the two scene image determine the vertical wavenumber of the data. There are obvious differences in the inversion effects with different vertical wavenumber. This paper defined the impact of vertical wavenumber on forest height inversion. 39 groups of simulated data and 8 groups of real E-SAR data with vertical wavenumber gradient change were used respectively on analyzing the impact of vertical wavenumber on interference coherence and coherent matrix range. And for each groups of data, the forest height inversions were accomplished with three-stage method based on RVoG model. The experimental results show that: 1) When the vertical wavenumber was small (kz<0.06), the interference coherence and the ratio of coherence matrix range of data were relatively small, the data independence was bad, and the decorrelation was serious, so the forest height inversion can not be carried out. 2) When the vertical wavenumber was larger than 0.06, the interference coherence and the ratio of coherence matrix range of data decreased with the increased of vertical wavenumber. The reliability of inversion results decreased gradually, and the decorrelation increased. 3) Optimal vertical wavenumber interval of forest height inversion was 0.06 to 0.10, and the inversion error was less than 15%. When the vertical wavenumber increased further, the inversion error increased significantly, which was not suitable for forest height inversion. We conclude that the data with vertical wavenumber between 0.06 and 0.10 can acquire desirable forest height inversion accuracy.

摘要:
Smart phones are mainly running Android, IOS and Windows Phone three mobile platform operating systems. The android smart phone has the best market shares and its processor chips are almost ARM software architecture. The chips memory address mapping mechanism of ARM software architecture is different with x86 software architecture. To forensics to android mart phone, we need to understand three key technologies: memory data acquisition, the conversion mechanism from virtual address to the physical address, and find the system's key data. This article presents a viable solution which does not rely on the operating system API for a complete solution to these three issues.

Global optimization problem;Krill herd (KH);Accelerated particle swarm optimization (APSO);Multimodal function
摘要:
To improve krill herd's (KH) ability for solving global optimization, by combining the advantage of KH and accelerated particle swarm optimization (APSO) method, an enhanced version of KH technique based on KH and accelerated APSO method, called particle-swarm krill herd (PKH) approach is designed. In this way, the advantage of the APSO and KH approaches are fully exploited, and the proposed PKH algorithm has the useful features originated from APSO and KH optimization techniques. The improvement includes the addition of APSO method serving as mutation operator when the krill updating for solving optimization problems. In PKH method, we used a novel type of elitism to store some best krill during the evolving stage. Eighteen standard testing problems are applied to evaluate these improvements and the results indicate that this metaheuristic method has much better performance than the original KH approach and six state-of-the-art metaheuristic algorithms. Our proposed PKH method significantly overtakes the other seven approaches. Moreover, KH is only inferior to PKH among eight methods. APSO and DE perform only worse than PKH and KH on eighteen functions. In addition, the parametric studies are also implemented to further show the robustness and generality of the proposed PKH approach in the present work.
摘要:

Coverage;Spatial and temporal dynamic changes;Random forest;Image dichotomy
摘要:
Vegetation coverage is an important model parameter in the study of changes in land cover changes, climate change, and other global ecological environmental impact factors. This paper used remote sensing images from 2000, 2005, 2011, and 2016 as data sources. Based on the NDVI pixel dichotomy, the coverage was calculated and the coverage was graded. The transfer matrix method and the difference method were used. The spatial autocorrelation analysis method was used to study the temporal and spatial dynamic changes of vegetation coverage. The results showed that the average coverage of the four phases of the study area was above 0.69, which were 0.78, 0.71, 0.69, and 0.69 respectively. The coverage of vegetation was better, but the overall coverage was declining and tended to be stable. Obviously, the phenomenon of aggregate distribution in the spatial distribution shows the rules of "high-high aggregation" and "low-low aggregation".

摘要:
Nowadays, spam is pervasive in the mailbox, and not only caused a waste of network resources, but also brings a lot of trouble to people's daily life. How to filter spam quickly and accurately is a challenge we are facing. For handling this challenge, this paper proposes a fast content-based spam filtering algorithm with fuzzy-SVM and k-means. First, K-means clustering algorithm is used to compress data with retain most of the effective information. Then, fuzzy support vector machine is used to train classification model, in order to deal with uncertain factors better. The experimental results show that this algorithms could improve the spam filtering speed and filtering accuracy rate effectively.

sulphur flotation;process control;optimal control scheme;control parametrization;differential evolution
摘要:
The optimal control of sulphur flotation process is difficult due to the unavailability of key process variables, complex process dynamics and the computational complexity in solving the corresponding Hamilton-Jacobi-Bellman (HJB) equation. In order to circumvent these difficulties, an optimal control scheme that integrates machine vision, control parametrization method and intelligent optimization is proposed. Machine vision is used to obtain the value of the unmeasured process variable, while control parametrization and a modified differential evolution algorithm work in a hierarchical manner to derive the optimal controller. A simulation study illustrates the effectiveness of the proposed scheme.

摘要:
We study scheduling on parallel two-stage flowshops in which each job has to pass through two operations: an R-operation and a T-operation. Motivated by the current research in data centers, we consider two restricted versions of the problem: one restricts that for each job, the R-operation consumes no less time than the T-operation, while the other assumes that the T-operation takes more time than the R-operation for each job. For the first case, we present an online 2-competitive algorithm and an offline 11/6-approximation algorithm. For the second case, we give an online 5/2-competitive algorithm, and prove, for the offline setting, that the problem can be reduced to the problem in the first case.

Multi-tenant;geo-distributed data centers;electricity price heterogeneity;immune algorithm
摘要:
In recent years, the global data center industry has entered a large-scale planning and construction stage, bringing huge power consumption and high operating costs. In this paper, a multi-tenant resource allocation optimization model for geo-distributed data centers is proposed to reduce the energy consumption and operating costs of cloud providers. Firstly, the resource allocation model is constructed by considering the heterogeneous electricity prices of geo-distributed data centers. Then an immune-based algorithm is proposed to solve the allocation optimization problem with variable users' demand. The biological immune system is a highly parallel, distributed, self-adaptive and self-organizing system with a strong ability to learn, recognize, and memory. It searches for the optimal resource allocation scheme with low computational complexity. Extensive simulations driven by large-scale Parallel Workloads Archive demonstrate the feasibility and performance of our immune-based optimization algorithm.
