PiMiair.org is a participatory indoor air quality data sharing project we launched in January 2014. Over 200 PiMi air boxes, a low-cost indoor air quality monitor, were given out to volunteer users across China. The PiMi air boxes measure the approximate indoor particulate matter concentration, and the ambient temperate and humidity. When a user accesses the PiMi air box for his personal air quality...
Anti-forensics is defined as a method undertaken to thwart the digital investigation process conducted by forensic investigators. In this paper we introduce the design and implementation of three novel anti-forensic approaches for data deletion and manipulation on three of the market-leading forensics tools. The evaluation results of our proposed anti-forensic approaches on a typical Android cell...
With the aim to further improve the intelligentization and the function of Computer-based test, this paper makes the recommendations to collect and track diversified data in the process of examinations, and to systematically analyze and process these data. The paper highlights the approaches of data acquisition, collection points and variable definition. This paper lays emphasis on the design and...
Data have become more and more important these years, especially for big companies, and it is of great benefit to mine useful information in these data. Oil & Gas industry has to deal with vast amounts of data, both in real-time and historical context. As the amount of data is significant, it is usually infeasible or very time consuming to actually process the data. In our project we investigate...
Earth Observation (EO) is an effective way to monitor hazards for rapid response. The sensors such as optical, passive microwave, Synthetic Aperture Radar (SAR) can be used. For rapid response purpose based on EO data, fast data acquisition from data provides and processing in near real-time are two key issues. In this paper, the automatic data integration method based on metadata harvest interface...
The concern about understanding the effects of climate change on the environment, such as the decline of pollinators found in nature, the need to support researchers to run experiments efficiently and to share those results, makes it necessary to study and develop virtual laboratories through the web, in order to gain greater insight on the behavior of bees, which is the main pollinator of plants...
We propose an effective acquisition scheme of sensor data in sensor network for healthcare support. This scheme can dynamically control quality and quantity of sensor data acquired from various sensor devices based on the inference of object person's health condition from real-time analysis of data stream related vital data. In this paper, we show the detail of our proposed scheme and its effectiveness...
According to the circulation process of financial indicators flow, data flow, capital flow involved in financial supervision work, based on the financial data center, designs a five-story architecture for the system including monitoring and analysis of budget preparation, monitoring and analysis of budget adjustments, monitoring and analysis of budget implementation, monitoring and analysis of accounts...
Information acquisition is an important part in the competitive intelligence system. With the development of network technology, network information has become an important information source of competitive intelligence acquisition. However, the complex and chaotic information on the Internet result in inefficiency of artificial collecting and processing intelligence. This paper has discussed the...
This paper presents the application of Kingview in the Held of industrial control, analyses the means of communication between Kingview and the coordinator or the end device in WSN (wireless sensor networks), and specially introduces communication principle and code realization between kingview and CC2430. This research can be widely used in many fields.
Based on the analysis of QQLive protocol, an active monitoring based QQLive real-time information acquisition system was presented by the in-depth study of characteristic message and characteristic payload in the communication process of QQLive. The system acquires the channel list and program information, at the same time monitors the viewing user information by forging the client to send message...
In order to meet the intensive and efficient mine construction, unit yield of the fully mechanized coal face should be improved constantly and reliability of production system in mechanized face must be further strengthened. Pressure monitoring technology and equipment in fully mechanized mining must adapt to the new developments. To achieve automation of mining pressure monitoring, problems such...
The paper presents an Advanced Digital Signal Inspector (ADSI) used for acquisition and analysis of the internal digital of a System on Package (SoP) with a limited number of pins. The system is made of a commercial FPGA-board, connected to the module for data sampling and controlled by PC via USB; a suited graphical interface allows for configuration, multi trace real time data display and post processing...
The ever increasing amount of content on the Internet has fostered many efforts seeking to leverage this potentially yottascale information source. Service systems using advanced data and text analytics techniques have been developed to perform knowledge gathering and information discovery over Web data. Information gathered from free and public sources on the Web is frequently integrated with enterprise...
Acknowledged and justified is the recognition of remote sensing as a powerful tool in land cover/land use monitoring for a large number of purposes ranging from agricultural practices to global ecology and environment protection. Data collected and information created from Earth observations constitute critical inputs to the sustainable management of the Earth - providing evidence for informed decision-making...
The paper introduced a novel on-line fault diagnosis system model of the hydropower units based on multi-agent system. In allusion to the classical MAS-based fault diagnosis model, it proposes a new function of information interactive between the mission-controlled subsystem and the task decomposition subsystem to increase the transmission rate of control signals and designs the status-monitoring...
Extraction and selection of proper signal characteristics is a significant step affecting the success of any subsequent data analysis. We describe a process used to extract features from a 6-year, single-channel Long Term Geoelectric Potential difference (LTGP) signal, recorded in 1998-2003 in Western Greece. Features are extracted from consecutive segments of the signal, and evaluated to identify...
A connection between the S3C2440, an ARM9-based 32-bit embedded MCU made by Samsung, and the ADS1274, a analog-to-digital converter with 24-bit, delta-sigma, data rates up to 128 k samples per second, allowing simultaneous sampling of four channels made by Texas Instruments, is presented. The driver based on the Windows CE5.0 that is an embedded operating system has been developed. Using fast interruption...
While numerous global initiatives exist to address the potential hazards posed by volcanic eruption events and assess impacts from a civil security viewpoint, there is still no single, unified, international system of early warning and hazard tracking for eruptions. Numerous gaps exist in the risk reduction cycle, from data collection, to data processing, and finally dissemination of salient information...
Voice-over-IP (VoIP) is a key component of next-generation-networks and rapidly becoming more and more common in the Internet in general. This also increases the demand of VoIP operators for a scalable, distributed and flexible monitoring. But current monitoring architectures are either not designed for including application layer protocol analysis and data acquisition, or they are very specific and...
