Analyzed the current situation of mobile operation and maintenance management. Detail designed and implemented the mobile operation maintenance management system according to Java EE, SSH framework, Information push technology and Android development etc. It has important practical significance for the future of the work of mobile operation and maintenance management.
In this paper, we concentrate on how to apply semantic technology (ST) to intelligence decision-making support system (IDSS). Due to the limitations of traditional IDSS with relational database and the superiority of ST in knowledge presentation, we establish a ST-based IDSS aimed at combining IDSS with ST which integrates expert knowledge with RDF triples. Pig disease diagnose is chosen as an example...
Mobile banking (m-banking) is a technology trend that is leveraged to become very important channel for banks to compete and deliver their services to customers. Knowing how to enhance this service is going to return positively on the earnings of the bank. This research paper studies the customer satisfaction while using mobile banking in Oman based on SERVQUAL model. The five factors of SERVQUA1...
Fuzzy Labeled Transition Refinement Tree (FLTRT) is a rigorous refinement model which supports abstraction and handling incomplete information and by the way reducing complexity of refinement process. It is based on Fuzzy Labeled Transition System (FLTS) which is a generalization of well-known Labeled Transition System, enhanced by fuzziness facility. The FLTRT structure serves as a tree of potential...
Recently many application are migrated towards cloud computing. It becomes an emerging field of research in software testing; moreover it is non-trivial to evaluate the performance of cloud services. Performance and load testing are one of the dominant means to evaluate the web-application performance. At the end of load testing performance analyst have to analyze thousands of performance counters...
Traditional workflow design tools which only provide the choreography of simple flow chart and do not provide a graphical configuration for access to a service, are unable to meet user demand for services. The article expands the Activiti Designer open source framework. It maintains communication through the bottom of the enterprise service bus, provides the registration services (OSGI, WebService,...
Lunar Relay Satellite plays a significant role in lunar science, manned lunar landing and lunar surface navigation. Compared with ground based telemetry and command methods, the approach applying GNSS (Global Navigation Satellite System) receiver to autonomous navigation system of lunar relay satellite has great application value. It can reduce the workloads of Deep Space Surveying Control Network...
DoS (Denial of Service) attack forces a cloud network node to handle few unauthorized access that employ unwanted computing cycle. As a result, the cloud node response is slow as usual and resource on cloud network becomes unavailable. Some Dos attacks are Ping of Death, Teardrop, Snork, Locking authentication, SYN flooding, Operating System Attacks etc. The most vulnerable incident happen when the...
Nowadays, while we are enjoying the convenience brought by such a huge repository of online web information, we may come across difficulties in finding the web pages we want related to particular information we are searching for. Hence, it is essential to classify web documents to facilitate the search and retrieval of pages. Existing algorithms work well with a small quantity of web pages, whereas,...
The next-generation of cloud computing will thrive on how effectively the infrastructure are instantiated and available resources are utilized dynamically. Load balancing, which is one of the main challenges in Cloud computing, distributes the dynamic workload across multiple nodes to ensure that no single resource is either overwhelmed or underutilized. An improved particle algorithm is proposed...
When Agent-based modeling and simulation is applied to researches on complex systems in different areas, the generality and normalization are usually insufficient, because there are differences between different target systems. So an abstracted method of describing multi-Agent systems is necessary. A method of model description of multi-Agent systems is put forward. It describes a multi-Agent system...
It is well known that UHF RFID, one of the key technologies of Internet of Things, is becoming the mainstream research of RFID applications. In a RFID system, reader plays an important role, however, RFID reader with only one channel often cannot satisfy the application requirements due to the complicated working environment. This study introduces a novel design solution of Four-channel RFID reader...
The wireless sensor network routing strategies determine the lifetime and the energy consumption of the sensor networks. An algorithm on calculating the approximate maximum network lifetime is presented by establishing the wireless sensor network routing strategy planning model. Through the simulation, the amount of information acquired during the network lifetime could account for 98.2% of the maximum...
Research and propose a path collection mechanism optimization scheme of AODV protocol. This scheme adopts the path collection mechanism in DSR protocol to improve the performance of AODV, meanwhile it avoids being affected by the high running overhead and weak scalability of DSR protocol. Results obtained by OPNET Simulation shows that the optimized AODV scheme performs effectively in terms of packet...
ECG signal quality is of great importance to real-time electrocardiogram(ECG) monitoring system. The paper introduces a new algorithm to evaluate the ECG signal quality. This algorithm is based on three features: heart rate score, spectral distribution ratio, and the variance between 12-lead ECG data. The result show that the proposed algorithm has a high Sensitivity of 95%, Specificity of 86.7%,...
In this paper, we consider the termination problems about uninitialized and initialized two variable homogeneous linear loops. Through analysing the properties of the boundaries of the set NT composed of all points on which a given uninitialized two variable homogeneous linear loop does not terminate, we reconstruct a group of simpler and complete quantified formulas to check whether a given uninitialized...
People with different personalities see a problem from several perspectives and make different decisions in a software project. Therefore, some researchers have associated software personnel's psychological personality types with the various tasks in recent years. But which psychological personality model is best suited to software engineering field has not been examined fully. This article discusses...
This article investigates the problem of distributed interference management in microcell systems, where many microcell base stations (MBSs) and user equipments (UEs) are randomly located and mutual interference only emerges between neighboring microcells. In addition, only local information can be utilized for each microcell. We propose a new resource multiplexing scheme-Soft Frequency-Time Reuse...
Because of the rapid growth of open source software, how to choose software from many alternatives becomes a great challenge. Traditional ranking approaches mainly focus on the characteristics of the software themselves. In this paper we investigate the market demands for software engineers, and propose a novel approach for ranking software by analyzing the market requirements for special software...
Modeling and analyzing the human tremor signal is necessary to avoid its negative effect for the fine operation. However, there are some defects in the traditional method for tremor signal analysis, which cannot resolve the localization contradictions in time domain and frequency domain. This paper proposes the statistical learning modeling method for tremor signal, which decomposes the tremor signal...
