To support legacy migration to service-oriented architecture (SOA), this paper presents a method that derives candidates of SOA services from procedural programs. In SOA, every service is supposed to be a process (procedure) with (1) open interface, (2) self-containedness, (3) coarse granularity for business. We identify such services from the source code and its data flow diagram (DFD), by analyzing...
EEG is represented to referential derivation with ear lobe reference and bipolar derivations for quantitative interpretation. When the ear lobe was activated, referential derivation with ear lobe reference was contaminated by ear lobe artifacts. In this study, the focus and extension of EEG components were estimated based on the cross spectrum of bipolar derivation. A referential derivation was constructed...
The digital watermarking scheme is designed for high quality music by using the direct-sequence spread spectrum technique. Both the un-detection probability for the music with the watermark and the erroneous detection probability for the music without the watermark are examined. Excellent results are obtained, that is, both of the probabilities are less than 10-8. The quality of the music embedded...
Creolization is a self-organization process of new language community. Thus far, a simulation study of the emergence of creoles has been reported in a mathematical framework. In this paper we introduce a scale-free network to the framework. We show that local creole communities are organized, regardless of the degree of exposure to non-parental languages, in contrast to the non-spatial model, and...
Organizations and enterprises have to constantly re-engineer and customize business processes to stay competitive in their market. These modifications and customizations result in a large number of similar processes that lead to high costs of deployment and maintenance. This paper presents a multi-layer architecture for efficient management of process variations. The approach consists of organizing...
We have investigated whether ultrasound changes our audible impressions when we listen to music or not. To solve this question, we verify that there might be a mechanism perceiving ultrasound by a physiological pre-experiment, and review discrepancy in subjective estimations for two kinds of sounds played back with and without ultrasound by a psychological experiment. In this paper, we study whether...
This paper proposes a contents-oriented cognitive network architecture as post-Internet. This architecture consists of three layers, that is, physical, semantic and application layers. Fluency function approximation-based unified coding of multimedia is one of key technologies. In semantic layer, both of cognitive function which corresponds to ldquointuition functionrdquo, that is, ldquopattern recognitionrdquo...
The University Public Key Infrastructure (UPKI) project in Japan is developing a national academic inter-institution authentication and authorization infrastructure based on the Public Key Infrastructure (PKI), and it is carrying out a feasibility study on SAML 2.0 federation by building a Shibboleth2.x test-bed called UPKI-Fed with about thirty university participants. Federation usually provides...
Human sleep stages wring whole night are usually classified into six stages based on polysommnographic (PSG) record. Sleep state of human light sleep changes gradually and continuously. In this study, automatic judgment of light sleep state in PSG record was developed. Parameters for characterizing the PSG were calculated from the periodogram and the discriminant function was constructed by using...
Many persons suffer from severe disabilities such as amyotrophic lateral sclerosis (ALS) caused by neurological disorders. Such kinds of disabilities bring various restrictions to communication and circumstance in their daily life. A simple communication method using neuro-biological signal will be effective and helpful to enhance their life quality. In this study, a simple on-off communication method...
Sleep apnea/hypopnea syndrome (SAHS) is one of serious sleep disorders. EEG arousals due to the apnea hypopnea are frequently appeared in polysomnographic (PSG) record in patients with SAHS. In this study, the method for detecting EEG arousals and apnea interval in PSG record was proposed for supporting visual inspection to classify respiratory levels and EEG arousals. Two threshold values were established...
A method for detecting spikes and slow burst in photic evoked electroencephalogram (EEG) was proposed. The spikes were detected by combining methods of the morphological filter and the similarity coefficient in the time domain. The slow burst was detected by using pole of AR model in the frequency domain. The proposed method was applied for the photic evoked EEG data containing spikes and slow burst,...
Water and energy are indispensable for human life. Fossil fuels such as oil and coal are usually used for power generation. However, the environment impact of these thermal power generation is relatively large. Moreover, the shortage of water caused by a population increase and global warming also becomes serial problem. In order to solve these energy and water problems at the same time, an integrated...
Visual mismatch negativity (v-MMN) in electroencephalographic (EEG) record provides an index of pre-attentive information processing of the brain. v-MMN is considered to reflect schizophrenia. The positive and negative syndrome scale (PANSS) is usually used in clinical diagnosis on patients with schizophrenia for estimating the degree of disorder. In this study, the relationship between v-MMN and...
