The difference in statistical scales will bring different statistical results, so it is important and necessary to select statistical grids for the geographical conditions information statistics. This paper proposes a method of selecting statistical scale of geographical information with spatial autocorrelation being taken into account. By using geographic conditions census data and taking building...
Bug fixing is one of the most important activities in software development and maintenance. A software project often employs an issue tracking system such as Bugzilla to store and manage their bugs. In the issue tracking system, many bugs are invalid but take unnecessary efforts to identify them. In this paper, we mainly focus on bug fixing rate, i.e., The proportion of the fixed bugs in the reported...
In isolated electricity networks the penetration of renewable energy sources offers, among others, the advantage of distributed electricity. At the same time, as penetration levels increase, controls and regulations need to be imposed in order to alleviate rising grid integration issues. Some of these can be prevented through the use of dynamic tariffs enabling Demand Side Management. In this work,...
Mobile marketing is a relatively easy and inexpensive way to promote products. This paper evaluates influential factors that motivate consumers in responding to mobile marketing with the consideration of context receiving time and location. A mobile marketing context model, with Technology acceptance model (TAM) and Commitment-trust Theory being adopted, is developed to facilitate purchasing intention...
This paper analyzes the impact on compensating for Type-I errors in video quality assessment. A Type-I error is to incorrectly conclude that there is an effect. The risk increases with the number of comparisons that are performed in statistical tests. Type-I errors are an issue often neglected in Quality of Experience and video quality assessment analysis. Examples are given for the analysis of subjective...
Detection of Sleep onset is one of complex processes in the area of sleep medicine. The transition from wake state to sleep is termed as sleep onset and is identified using distinct markers like behavioural features, physiological features and changes in EEC Extraction of appropriate features from EEG recordings helps in automated recognition and classification of wake-sleep transition. This research...
In 2011, Taiwan officially implements 12-year basic education. Problems arise due to lack of time to conduct planning and relevant empirical study. It requires respective endeavor from the academic circle to resolve the 12-year basic education plight via empirical study. The study first concentrates on the following five questions to conduct empirical study and provide future reference for the education...
In the modern enterprise system, business management and ownership are separate. Thus, the agency relationship comes out. Under the asymmetric and insufficient information, the manager would be contrary to the pursuit of business objectives and maximize their own interests, resulting in agency costs. Western countries have been respected that debt financing plays very good constraint on managers,...
Through taking the county level as the unit, per capita GDP, net income of the rural households and disposable income of urban residents as the evaluation indexes, and 42 counties in Yunnan central urban agglomeration as the research objects, the spatial-temporal pattern difference of Yunnan central urban agglomeration's economy from 2002 to 2011 is studied in this paper based on Geoda and ArcGIS...
In this paper, a subjective assessment methodology based on ranking, reordering and image categorization is proposed. It is designed to facilitate the evaluation of complex features such as monocular depth cues in natural images. These features can be particularly challenging to explain to test participants, and the proposed methodology is designed to provide to the test participants more insights...
DoS attack is the threat to ICT (Information and communications technology) society. There are many existed detection methods, but countermeasures has been become difficult according to complication of attacks. In conventional methods, entropy-based methods detect attacks using the property of entropy that it enables to estimate increase and decrease of dispersion of header information values, like...
A comparison between two established MOSFET mismatch modeling approaches, one based upon the use of uncorrelated random physical variables and one based upon the use of correlated random model variables where the correlation is ignored, is presented. An analytical formulation is introduced that enables the designer to easily predict the relative errors in matching performance that will occur if the...
Lijiang River Basin (LRB) has witnessed intensive human activities in the past 20 years, due to its unique karst landform, which has attracted a large amount of tourists. During this period, land cover changes were impacted by rapid expansion of road network substantially. This paper analyzes the interactions between road network and land cover change in the LRB by statistical analysis on both random...
There are many methods in statistical analysis, but the basic approach is quantitative analysis. Statistical analysis requires a combination of quantitative and qualitative analysis. Qualitative analysis is fundamental, and a quantitative analysis, which is the core of statistical analysis, is based on the precision of the qualitative analysis. The process of statistical analysis includes qualitative...
Households constitute an important target group for energy conservation. Understanding the occupant's behavior and defining the factors that considerable affect the electricity consumption will contribute to improving the energy performance of buildings. An online survey was therefore conducted and 221 questionnaires were completed to provide the necessary data. The present study links the demographics...
Condition Monitoring is the process of recognizing machine health status, by analyzing the various parameters of machine. For Acoustic Emission based condition monitoring, generally acoustic data needs to be taken from several positions and analyzed, which can be cumbersome and many times economically not viable. Thus there arises a need to define sensitive positions. Sensitive positions are positions...
Patient flow, on one hand, represents the progression of a patient's health status; on the other hand, can be thought of the transferring of patients through multiple hospital units within a hospital or among different hospitals. Furthermore, patient flow, in the aggregate, is equivalent to the demand for health care services. Thus, patient flow management is of great importance to monitor and control...
These days, many scientific projects such as: SETI@home and Distributed.net are using computers which are connected to internet from the entire world in order to run their jobs. This large distributed system is a Volunteer Computing (VC) that includes volunteer hosts. An important attribute of volunteer hosts is the volatile behavior that means often they are not available because of the autonomy...
Pseudorandom number generators are used for session key generation, simulation and games, and other applications that need long bit sequences which posses a lot of qualities like large cycle length and uniform distribution over the range of number domain. There are many state of art algorithms present. This paper is the result of an effort to develop a new Pseudorandom Number Generator that can be...
Random telegraph noise (RTN) has become an important reliability issue at the sub-65nm technology node. Existing RTN simulation approaches mainly focus on single trap induced RTN and transient response of RTN, which are usually time-consuming for circuit-level simulation. This paper proposes a statistical algorithm to study multiple traps induced RTN in digital circuits, to show the temporal distribution...
