While there has been significant focus on collecting and managing data feeds, it is only now that attention is turning to their quality. In this paper, we propose a principled approach to online data quality monitoring in a dynamic feed environment. Our goal is to alert quickly when feed behavior deviates from expectations. We make contributions in two distinct directions. First, we propose nov...

At present situation travel becomes the biggest hassle for everyone. In this proposed research paper I have used GPS system to find out the shortest path to make your travel at ease. Through this navigation process it is clear-cut for us to find out right path. In this process, it is possible for an individual to analyse the exact shortest route from multiple paths. With the information from th...

Abstract An Intrusion Prevention System (IPS) analyzes each packet for malicious content before forwarding it and drops packets that originate by an intruder. To do so, the IPS has to be physically integrated into the network and needs to process the actual packets that run through it, instead of processing copies of the packets at some place outside the network. Therefore, independent of the w...

EQuB is an overlay mechanism to Ethernet’s MAC protocol that provides QoS guarantees to real-time applications. In its basic form, EQuB relies on the sensing and collision detection abilities of standard network interface cards and, in addition, requires only that those cards be capable of sending jam signals—so called black bursts—of pre-specified durations. EQuB gives access priority to realt...

This paper presents a robust and exible method for the extraction of mouth corners from videophone sequences. Robustness is referred to illumination conditions, speaker variability, pose and image quality, while exibility is given by the fuzzy environment which allows to eÆciently perform the fusion of several sources of information.

The problem of detecting and eliminating duplicated data is one of the major problems in the broad area of data cleaning and data quality in data warehouse. Many times, the same logical real world entity may have multiple representations in the data warehouse. Duplicate elimination is hard because it is caused by several types of errors like typographical errors, and different representations o...

Classification of various rice types and determination of its quality is a major issue in the scientific and commercial fields associated with modern agriculture. In recent years, various image processing techniques are used to identify different types of agricultural products. There are also various color and texture-based features in order to achieve the desired results in this area. In this ...

Following a brief discussion on various aspects of data quality, possible methods are examined for the detection of errors in a spatial database. Using examples, we introduce the consistency checking method based on spatial relationships among neighboring objects and attribute relationships among map layers from different sources. Using logical relationships among spatial neighborhoods and amon...

Due to the characteristics of mobile networks such as low speed, high error bit rate, variable link throughput etc, the applications over the wireless channel face with many challenging problems, especially multimedia applications, where the volume of data is huge. Without a suitable control, the Quality of Service (QoS) of such applications is adversely affected and the connection quality may ...

The work presents the results of inconsistency detection experiments on the data records of an atherosclerotic coronary heart disease database collected in the regular medical practice. Medical expert evaluation of some preliminary inductive learning results have demonstrated that explicit detection of outliers can be useful for maintaining the data quality of medical records and that it might ...
