In recent years competition among retailers has led to intense competition among supply chains. The rise of the Internet of Things provides a basis for retail enterprises to have detailed knowledge of their supply chain and hence to enhance its management. Using the Internet of Things, retail enterprises are able to increase the quality of their supply chain management, so as to offer a more intelligent...
The purpose of data mining is to explore, find and hence analyze relevant data from a massive data source using various technical means. This paper introduces the development of data mining to date, its functions, tasks and algorithms, as well as the process of data mining. The application and problems of data mining are also presented and finally the potential future development of data mining technology...
Packaging currently used in the market often results in a waste of resources and environmental pollution. The implementation of green packaging can reduce pollution, optimize the environment, improve international competitiveness, promote the development of export trade, and is also conducive to the implementation of sustainable development strategies. However, despite the existence and benefits of...
The mobile video playback involves many subsystems of the devices such as computing, rendering and displaying subsystems. Among all subsystems, the displaying subsystem accounts for at least 38% of all consumed power, and it can be up to 68% with the maximum backlight brightness. What is more, lots of people watch videos via mobile devices in various situations, where the ambient luminance condition...
Display devices at bit-depth of 10 or higher have been mature but the mainstream media source is still at bit-depth as low as 8. To accommodate the gap, the most economic solution is to render source at low bit-depth for high bit-depth display, which is essentially the procedure of de-quantization. Traditional methods, like zero-padding or bit replication, introduce annoying false contour artifacts...
Bearing-only filtering algorithms used in submarine tracking commonly assume that the target and ownship move in the same plane. In real-world scenarios, the target and ownship may actually move in different planes, since it may be advantageous for the ownship to do so. Tracking of the target for this scenario can be accomplished by using passive bearing and elevation measurements. Then the algorithm...
Nowadays big data is being used to create wealth in many fields, in particular e-commerce is playing an increasing role in modern life and the role of big data in this sphere is constantly evolving. The demand for e-commerce is creating massive amounts of data all the time and traditional processing techniques and ways of thinking have been unable to cope with it. Thus big data methodology has the...
Near-infrared spectroscopy (NIRS) is a rapid, chemical-free, easy to use, and non-destructive analytical technique that has been widely applied to a diverse range of fields. NIRS analyzes the investigated samples through their NIR spectra. However, NIR spectral data are complex and multivariate, so multivariate data analysis methods (chemometrics) are used to interpret and predict the spectra's chemical...
The computing paradigm of MapReduce is popular for data analysis since the volume of data to analyze grows rapidly. Hadoop, an open-source implementation of MapReduce, is the most popular framework for MapReduce programs. But it still suffers from the job delay caused by node failure and task failure. This paper proposes a novel Task Recovery mechanism based on Checkpointing Intermediate Data (TRCID)...
Cloud computing brings a rapid way for enterprises to launch a new software, which needs lower cost compared with self-purchased infrastructure. More and more enterprises compact their business software as services into cloud platform to the users. In service auction, the service provider aims to make more profits from the service it provides, but the service consumer hopes to select a good quality...
Nowadays, camcorder piracy has great impact on the motion picture industry. Although some watermarking technologies can track the movie pirate, the video content viewed in the theater may be affected and they cannot obstruct the need of pirated movie because the watermarks in pirated moves are invisible. This paper presents a new method to defeat camcorder piracy and realize content protection in...
With the frequent occurrence of large-scale disasters, such as landslide and earthquake, timely and effective emergency resource scheduling becomes more and more important. Lots of disasters need multi-period rescue to satisfy the demand of disaster areas. In order to find a better plan to achieve the multi-period disaster relief, in this paper, a multi-period emergency resource scheduling problem...
In this paper, we propose an enhanced projector using the emergent display technology of Temporal Psycho-Visual Modulation (TPVM) which exploits the difference in image formation mechanisms of human eyes and imaging sensors. The projector have two significant advantages compared to traditional projector: 1) parts of the information (e.g., speech notes) projected can be hidden from the audience but...
The design of robust networked structures is of significance in reality, and the integrity of network connections has been greatly emphasized in previous studies. However, besides structural integrity, a system should also keep the functionality when suffering from attacks and failures, i.e. robust community structure. Focusing on enhancing community robustness on complex networks, in this paper,...
The emergency logistics scheduling (ELS) is to enable the dispatch of emergency supplies to the victims of disasters timely and effectively, which plays a crucial role in large-scale disaster relief. In this paper, we first design a new multi-objective model that considers both the total unsatisfied time and transportation cost for the ELS problem in large-scale disaster relief (ELSP-LDR), which is...
Existing studies indicated that it is crucial to design network structures with well tolerance against potential attacks and failures in reality, and several attack models have been proposed and lucubrated. Aiming at enhancing network robustness suffering from edge-based attack cascading failures, we first propose a measure, Rce, to numerically evaluate the robustness of networks under cascading failures,...
Industrial wireless mesh networks technologies as WirelessHART, ISA100.11a, WIA-PA, e.g., have become a communication infrastructure for process control in harsh and noisy environment. These control systems are wireless mesh networked control systems (WMNCSs). Compared with wireless sensor networks, the Wireless network control systems have more stringent requirements on reliability and real-time...
Ever since Chinese electric power reform in 2002, different live test approaches were introduced and applied in relative industries. There were at least 26 live test approaches applied in the field of power transformation, power transmission and power distribution. The essay introduced a comprehensive dynamic and flexible effectivity evaluation system, which helped to evaluate the strengths and weaknesses...
As an important tool for data analysis and knowledge processing, formal concept analysis has been applied to many fields. In this paper, we introduce a new visualization method of a concept lattice and the attribute partial order structure diagram (APOSD), we obtain the analysis method of the daily variation characteristics of PM10 concentration. Through in-depth analysis of the APOSD by granulating...
In this paper, we consider the concept of modified soft rough sets (MSR-sets) which was introduced by Shabir et al. [20]. We establish that MSR-sets can be viewed as a class of classic Pawlark rough sets.
