A data bank can provide very useful information while mined properly.[27] In order to be optimally extracted, data mining can be done by observing capacity and characteristics of the data; so it can generates Knowledge Discovery in Databases as expected. For instance in Gene Bank, every single record of DNA, there are at least ten thousand sequences recorded. If the data is more than a hundred records,...
In the simulation-on-demand paradigm, we invest computational effort by running a simulation experiment before a question is asked, and then we quickly provide an answer by making use of the results of the earlier simulation experiment. This can be done by building a metamodel, but standard metamodeling methods used in stochastic simulation have the disadvantage that they require validation. We show...
Generation of problem sets and quizzes forms animportant part of education technologies. Although some systemshave been built for quiz generation, they mostly focus on abstractlogic and mathematical constructs. Knowledge in other domainsis relational rather than propositional, and many systems usededicated knowledge databases. We present a method to presentthis knowledge in the form of objective question...
The Kidney Transplant Process Model (KTPM) was created to demonstrate the kidney transplant process from initial placement on the waiting list to life post-transplant. The KTPM focuses on the effects of donor availability on the entire transplant process with a specific concentration on ethnicity. The model was designed as a tool for analyzing the transplant process and its outcomes, supplemented...
"Scenario-Respond" are the most efficient model for unconventional emergency management, and the scenarios are the foundation to deal with the unconventional emergency, therefore how to build and deduce the scenarios are important research parts of "scenario-respond". From the respective of cognitive science, the paper built a scenario deduction framework based on the knowledge-unit...
Achieving coverage closure is consistently identified as one of the most difficult challenges during the functional verification of today's HW designs. Constraint random testing as well as coverage directed test generation (CDTG) techniques have been proposed previously with different degree of success. This paper presents a framework for speeding up the coverage closure of the design under verifications...
Social networking websites are considered as major sources of opinions and views of the public on the prevalent social issues at a given point in time. Websites like the Twitter1 reflect the public views through its millions of messages posted by its users world wide, whenever a controversial issue arises in the society. It is during this time that we observe significant amount of malicious, violent...
Application specific intrusion detection methods are used to detect network intrusions targeted at applications. Normally such detection methods require payload or packet content analysis. One of the prominent method of payload modeling and analysis is sequence or ngram modeling. Normally ngrams generated from a packet are compared with a database of ngrams seen during training phase. Depending on...
Software testing is an essential activity in software development process that has been widely used as a means of achieving software reliability and quality. Software practitioners rely on test coverage to decide whether software under test has achieved an acceptable level of reliability and can be released. The researchers in the field of software testing focus on defining meaningful test coverage...
On-line analytical processing (OLAP) provides analysis of multi-dimensional data stored in a database and achieves great success in many applications such as sales, marketing, financial data analysis. OLAP operation is a dominant part of data analysis especially when addressing a large amount of data. With the emergence of the MapReduce paradigm and cloud technology, OLAP operation can be processed...
Multi product lines (MPLs) are systems consisting of collections of interdependent software product lines (SPLs). The dependencies and interactions among the SPLs cause new challenges in variability management. In the case of a large-scale information system MPL, important issues are raised regarding integration of the databases of the individual SPLs comprising the main system. The aim of this paper...
Techno-economic analysis is used to evaluate technological solutions in different business environments via a simulation based approach. Four steps can be observed in techno-economic analysis: scope definition, modeling of costs and revenues, evaluation of the different solutions and refinement of the analysis. During the scoping step, the boundaries of the analysis are determined, the problem is...
The main objective of the paper is to analyze of the behavior of patients (as well as the doctors and surgeons) referring to a private hospital for treatment in Thailand. The main idea is to investigate and scrutinize the relationships of the patients and the relevant physicians during the treatment process based on an event log previously collected from the information system of the hospital. Accordingly,...
The recent growth of interest for in-memory databases poses the question on whether established prediction methods such as response surfaces and simulation are effective to describe the performance of these systems. In particular, the limited dependence of in-memory technologies on the disk makes methods such as simulation more appealing than in the past, since disks are difficult to simulate. To...
Identifying the prescription patterns would be a useful and interesting goal from multiple perspectives. Firstly, the identified patterns could expand the horizon of the medical practice knowledge. Secondly, the identified prescription patterns can be evaluated by subject-matter experts to label some of the patterns as anomaly calling for further investigation, i.e., prescription costs for insurance...
Distribution utilities are facing challenges arising from rapid technology developments coupled with strong drivers to minimize operating and capital expenditures. Embedded generation including solar rooftop PVs and other demand management means do not only change the demand profile of the system but also other electrical characteristics of the distribution network. Advanced power system analysis...
In active orthoses for paraplegic users, it is essential that the devices replicate the user's leg movements. This is usually performed through joint position control, where each orthosis joint follows a specific angle trajectory as a reference. The most commonly used approach for generating this required references is to create a set of average joint trajectories from a gait database, and use them...
In this paper unified structure formation method (ETL) development for operative analysis of data stored in different SQL and NoSQL databases are considered. Unified structure formation method (ETL) is based on work with Map Reduce parallel model. In order to perform the method following steps should be considered: development of searching forms (pattern) for data searching in different database,...
Many scientific fields generate, and require manipulation of big data. Known scientific data analysis systems, as well as traditional DBMSs, follow a pull-based architectural design, where the executed queries mandate the data needed. This design, while suitable for traditional transaction-based workloads where number of queries retrieve small parts of data located at various places of the database,...
In this study, we investigated firm activity data in 2008 and 2014 in the United States and Japan. We reconfirmed that the decay rate of firm activity does not depend on firm age in Japan. This is consistent with the observation that firm age distribution follows an exponential function in Japan. At the same time, in the United States, we found that the decay rate of young firms is high and it becomes...
