The paper suggests very fast electronic solutions for priority buffers that take data from many potential sources, accumulate them in a register, and output the most priority item in run time in such a way that as soon as a new value arrives it is included in the set with all previously received and untreated items and properly handled. It is shown that such circuits are required for real time embedded...
Traditional vehicular routing protocols cannot accurately foresee future location of each vehicle for efficient packet forwarding. Recently, the data mining approach has been applied to analyze huge vehicle trajectory data. In this paper, we propose a novel trajectory-based routing (NTR) protocol to improve the packet replication efficiency of vehicles in the Vehicular Delay Tolerant Network (VDTN)...
Higher Education Institutions store a sizable amount of data, including student records and the structure of a degree curriculum. This paper focuses on the problem of identifying how closely students follow the recommended order of the courses in a degree curriculum, and to what extent their performance is affected by the order they actually adopt. It addresses this problem by applying techniques...
When it comes down to public transport systems, delays are a hot topic. For a quantitative conclusion whether a delay is just an incident or happens on a regular basis, we have to believe in the figures published in the annual reports of public transport companies. However, even if some data is available online, it is quite hard to independently examine these numbers without information technologies...
One of the considerable initiatives towards creating a smart society could be the guarantee of a smart, resilient and reliable power grid. As an attempt to improve the electricity supply service, it would be meaningful for the distributed system operators (DSOs) to be able to monitor the current status of the grid. The prediction of future possible critical situations would then be feasible using...
Cooperation combat of multi-UAV could improve the combat effectiveness and survivability. Cooperation architecture is the base of cooperation. To overcome shortcomings of the existing cooperation architectures, the workflow-based multi-UAV cooperation combat architecture is proposed. Performances of the proposed new architecture are analyzed and verified. Experimental results show that, in the given...
We present SIRUM: a system for Scalable Informative RUle Mining from multi-dimensional data. Informative rules have recently been studied in several contexts, including data summarization, data cube exploration and data quality. The objective is to produce a small set of rules (patterns) over the values of the dimension attributes that provide the most information about the distribution of a numeric...
Behavioral and targeted profiling of users is an important task in marketing and in the advertising industry. Being able to match a given user profile to an advertising that leads to effective purchases is challenging because of a very tiny proportion of users willing to purchase goods and thus monetize the advertising. With such proportions being less than one percent of the overall user population,...
This paper presents a method to obtain delay rational macromodels of electrically long interconnects from tabulated frequency data. The proposed algorithm first extracts multiple propagation delays and splits the data into single delay regions using a time-frequency decomposition transform. Then, the attenuation losses of each region are approximated using the Loewner matrix approach. The resulting...
Many software development projects have introduced manda-tory code review for every change to the code. This meansthat the project needs to devote a significant effort to re-view all proposed changes, and that their merging into thecode base may get considerably delayed. Therefore, all thoseprojects need to understand how code review is working, andthe delays it is causing in time to merge.This is...
Distributed cache at mobile user devices and small base stations (SBSs) can improve the efficiency and reduce the delay for content dissemination in heterogeneous cellular networks (HetNets). One major challenge lies in the limited storage capacity of the participating mobile devices and SBSs. This paper investigates the design of an effective distributed content cache policy with heterogeneity (DCP-H)...
On an average day in the United States, thousands of commercial flights make their way through more than 5,000,000 square miles of U.S airspace. People rely on these flights for business and pleasure needs. Flying can be a very frustrating experience. Data mining past flight data can help consumers make informed decisions about many aspects of flying such as when the best days to fly are and out of...
Streaming classification is well studied in the machine learning community. In real-world applications labels for previously observed feature vectors may only arrive after appreciable lag — that is, the labels are delayed. These delayed labels are an important aspect of streaming analysis, one that is not properly appreciated or addressed in the literature. This paper provides a taxonomy of delayed...
Conventional echo hiding methods have simple encoding and decoding process, Robustness to MP3 compression, but the correct rate of extracted information need be improved. To copy with this problem, we propose a time-spread echo with random intervals. The encoding process generates an interval sequence to dominate the intervals of echoes. The echo is added into the audio according to the interval sequence,...
Air traffic management (ATM) initiatives are developed and implemented to mitigate delays caused by uncertainty in weather and demand at an airport. ATM decisions are made by traffic flow management specialists, based on their judgment and experience. Historical data on airport operations can be used to assist decision-making by intelligently augmenting controller experience with a more systematic...
Digital down-conversion technology based on the structure of bandpass sampling is one of the key technologies of software radio receiving system. While the traditional digital mixing orthogonal demodulation using multiplier, to a certain extent, increase the computational complexity. This paper proposes a kind of digital down-conversion design based on polyphase filtering structure, effectively reducing...
Echo hiding algorithm is a type of Information hiding technology which has been widely used. This paper introduces the principle and the mathematical model of echo hiding algorithm. Generally, the traditional echo hiding algorithm just allows to hide 180 bits of information in 1 second, in order to increase the hiding capacity, we proposed multiple delayed position of echo hiding algorithm. It permits...
Advances in fusion of disparate social media and hard-soft sources have made it possible to extract relational information in the form of social network graphs. Periodic measurements of communication between individuals in an area of interest can be modeled in the form of a random graph. In this paper we are interested in detecting the emergence of a social network community where a subset of individuals...
The internet play an vital role in accumulating the Data, even from different location, easily available to all users all over the world. However, the majority of this data are not of much concern to most of the web users as their interest vary over the time. Nowadays there exists more than a billion web sites providing necessary information to users with precise data within fewer page access delay...
E-commerce is one of the fast growing business models of the present day. Shopping from anywhere & anytime has become a key feature of E-commerce. Because of the huge amount of data generated from the vast population of people & connected devices has posed challenges to manage the stream of data arriving from every device in real time. Big data analytics is a process of examining this big...
