Continuous evolution of virtualization-related technologies have benefit greatly flexibility and reliability of software system. However, although virtualization removes binding between application and server underneath, it complicates the regular runtime hierarchy into an intricate structure, where cross-layer monitoring and holistic evaluation becomes challenging. Currently lots of monitoring practices...
Peach is one of the most important commodities in the global fresh product market. With the development of people's living standard, consumers pay more attention to the internal quality of fruits than the appearance quality of fruits. The requirement of nondestructive analysis could be satisfied by near infrared (NIR) spectroscopy with appropriate data analysis methods. In this paper, we measured...
Apple plays an important role in modern agricultural economic. With the international trade competition and focus of apple consumption has been transferred from appearance quality to internal quality. Currently, people pay more attention to the potential of near infrared spectroscopy in nondestructive detection of fruits. In this paper, we measure the spectrum, sweetness and acidity of apples, use...
Sailing Monitoring System operating in the sea area has the basic transmission requirement of low power and long range. LoRa Low Power Wide Area Network (LPWAN) technology can be seen as an alternative solution to address this problem. This study focuses on transmission performance of LoRa technology and attempts to apply LoRa technology to Sailing Monitoring System. Experiments of LoRa technology...
NDN (Named Data Networking) is an increasingly important topic with the realm of the future Internet architecture research. Naturally, a new congestion control mechanism is important for a new Internet architecture. Existing research on NDN congestion control mainly considers the one-Interest-one-Data transport mode, internally, they control the Data sending rate by adjusting the Interest sending...
This paper analyzes the energy consumption characteristics of CNC machining process and exploits the critical factors for energy efficiency improvement through a theoretical analysis, based on which a series of operation strategies are presented to enhance energy efficiency of CNC machining. A set of experiments are carried out to demonstrate the performance of the proposed operational strategies.
Urban functional zones refer to areas (or regions) of a city which provide specific urban functions for peoples who lived in the city. The spatial layout of buildings in functional zone show a specific pattern, e.g. residual areas usually have similar builds and the positions of which are highly organized. In this paper, we show that it is possible to identify urban functional zones from a remote...
In this work, we present a newly titanium-contained periodic amorphous carbon(a-C) composite films by magnetron sputtering process on silicon (100) substrate which has lower intrinsic compressive stress that can be used in electrical modulation pulsed MEMS infrared(IR) source for NDIR gas sensors. The fabrication process, results, performance and results analysis are then carried out.
As a typical information-centric networking architecture, Named Data Networking (NDN) has attracted wide research attentions in recent years. Since NDN transport has new features of multi-source and multi-path, the implicit congestion detection mechanism of the traditional TCP protocol based on a single source and a single path is no longer suitable for NDN. In this paper, we propose a novel NDN congestion...
In high bandwidth and low latency data center networks, when multiple data senders simultaneously communicate with a single receiver, namely in many-to-one communication pattern, it is frequently occurred that the burst data overload the receiver's switch buffers, which leads to TCP throughput collapse. This phenomenon is termed to TCP Incast problem, which has become a new hot research topic in recent...
Increased network traffic has put great pressure on edge router. It tends to be more expensive and consumes more resources. Buffer is especially the most valuable resource in the router. Given the potential benefits of reducing buffer sizes, a lot of debate on buffer sizing has emerged in the past few years. The small buffer rule, for example, was challenged at edge router. Instead of buffer sizing,...
Named Data Networking (NDN) is currently a hot research topic in the field of network architecture, and its transport control mechanism is one of the key technologies needed to be studied. Since the transport in NDN network has the characteristic of multi-source, the implicit congestion detection mechanism of the traditional TCP protocol is no longer suitable for the NDN network. In this paper, we...

This paper presents a remanufacturing process planning and resource scheduling method. A color Petri net is proposed to model the dynamics in remanufacturing, such as various process routings and different processing times for components in the same process. A hybrid meta-heuristic using simulated annealing and tabu search is also proposed to derive the optimal process plan and schedule that minimize...
This paper proposes an optimization model and a simulated annealing-based solution for a dynamic layout problem in remanufacturing. The approach is demonstrated through a machine tool remanufacturing system.
Trip-out rate plays a very important role in the research of stable operation of power system, so trip-out rate forecast has become an urgent problem. combining with the characteristics of the grey theory, a catastrophe prediction model about trip-out rate was set up based on the original data. A trip-out rate threshold was established and the data exceeding it was considered abnormal. The time when...
This article studies agricultural product transfer process, and gets the reason for that the price gap between the origin and the final markets becomes bigger. By analyzing of enterprise's behavior, this paper demonstrates the feasibility of vertical constraints of agriculture prices to save cost. The final conclusion of the paper is that the vertical constraints can improve the cooperation efficiency...
Herein, we propose a novel resilient forwarding mechanism to address the contradictory problem between transmission performance and power saving problems. Through automatic backup and transmission line switch, self-healing and autonomous troubleshooting can be achieved for online monitoring in transmission grid. Autonomous surveillance transmission network can be achieved through transmission line...
This paper introduces a method of Snowbelt flood risk early-warning in Xinjiang Province. Firstly, snow water equivalent is inversed from snow depth of AMSR-E data. Then the analysis points above threshold of catchment area and upstream of residential area are selected. The instantaneous flow value Qpand maximum allowable flow Qt of analysis points are calculated. The points with ratio value of Qpand...
In the paper, scale parameter of Schrödinger transform of image is discussed. First, the experiments show Schrödinger transformation of image can be seen as the result of primitive image shrinking inside and spreading outward at the center of object, like as interference wave, and the bigger the parameter a is, the more obvious the interference is, on the other hand, contour curves of object in the...
