We research the multimedia information hiding (MIH) which is a technology to overlay digital information on multimedia contents such as picture, sound, document, etc. As application to disaster management of MIH, we have developed a new technology called "PAIH" (Public Address Information Hiding) which is a technology to overlay information such as position or destination on siren sound of urgent vehicles. Siren sound is allowed to degrade of sound quality, but PAIH is required to decode correct information from siren sound with pitch shift (Doppler effect) or under noisy environment.

An experiment was performed for the observation of H emission induced in a cooled laser-induced atmospheric pressure gas plasma of He atoms in their metastable excited state. The strong H emission detected clearly established, to the exclusion of other well known major excitation processes, the exclusive contribution of the He-induced excitation (HIE) mechanism. The process is suggested to take place by means of energy transfer from the excited He atoms to the H atoms via Penning collision induced ionization involving electron exchange. The result further shows that this mechanism may also work for elements other than H and thereby strongly suggests the use of ambient He gas to broaden and complement the applications of standard laser-induced breakdown spectroscopy. © 2011 American Institute of Physics.

Aiming to answer the growing demand for professionals with knowledge about software processes, this article presents ideas for using educational tools that supports its teaching, through realistic experiences away from risks of real projects. The paper defines four options of prototypes of interfaces with specific characteristics which were evaluated qualitatively by applying the verbal decision analysis (VDA) methodology ORCLASS to classify them in decision groups, structured on the decision maker's preferences obtained through the interview. The objective is to use the interfaces of the approved group for future development of real educational tools applications. ©2010 IEEE.

Glutamine synthetase (GS) is a key enzyme in nitrogen metabolism in plants. One of the GS isoforms in plants, GS1, is transcriptionally regulated. Our recent studies show that a soybean GS1, Gmglnβ 1, gene is posttranscriptionally regulated by its 3′UTR. It is of interest to know if the 3′UTR-mediated posttranscriptional regulation of GS1 genes is a universal phenomenon or is it limited to Gmglnβ 1 gene only. The 3′UTR-mediated posttranscriptional regulation of alfalfa GS1 genes (MsGS100 and MsGS13) was investigated using both computational and biological approaches. For our first set of study, we used CisFind, a software tool that identifies unextendable common patterns among sequences, to analyze the 3′UTRs of GS1 genes. CisFind analysis of the 3′UTRs showed that the 3′UTR of MsGS100 shared common putative cis-element motifs with the Gmglnβ 1 3′UTR whereas these elements were absent in the 3′UTR of MsGS13 gene. The computational results were verified using transgenic approach, and the results confirmed the computational analysis. The 3′UTR of MsGS 100 plays a similar role as the 3′UTR of Gmglnβ 1 gene in posttranscriptional regulation of a reporter gene while the 3′UTR of the MsGS13 does not. CisFind, was also used in analyzing the region in the 3′UTR of MsGS13 that could be responsible for its nodule enhanced expression (by detecting putative cis-elements that are overrepresented in the 3′UTR of nodule-enhanced GS1 genes).

Virtual and augmented medical imaging environments: Enabling technology for minimally invasive cardiac interventional guidance

Virtual and augmented reality environments have been adopted in medicine as a means to enhance the clinician's view of the anatomy and facilitate the performance of minimally invasive procedures. Their value is truly appreciated during interventions where the surgeon cannot directly visualize the targets to be treated, such as during cardiac procedures performed on the beating heart. These environments must accurately represent the real surgical field and require seamless integration of pre- and intra-operative imaging, surgical tracking, and visualization technology in a common framework centered around the patient. This review begins with an overview of minimally invasive cardiac interventions, describes the architecture of a typical surgical guidance platform including imaging, tracking, registration and visualization, highlights both clinical and engineering accuracy limitations in cardiac image guidance, and discusses the translation of the work from the laboratory into the operating room together with typically encountered challenges. © 2008 IEEE.

Crystal growth of Rb2CdI4 was performed by Czochralski method. Transparent colourless crystals with monoclinic structure were obtained. Temperature dependence of the dielectric constant along the b-axis was measured with variation of frequency. The thermal expansions x i (i = a, b, c and a′;a′ = a + c) along the four independent axes were measured both by clip-type strain-gauge dilatometer and X-ray diffraction methods. These results show distinct anomalies associated with the ferroelectric transition at TC= 210 K. Copyright © 2010 Taylor & Francis Group, LLC.

Nowadays, software organizations have needed to develop excellent and reliable products. This scenario has helped to increase the relevance of quality assurance activities, especially the testing discipline. However, sometimes the time and resources are limited and not all tests can be executed, demanding organizations to decide what use cases should be tested, to guarantee the predictability of the project's time and *** multiple criteria methodologies support decisions, considering many factors, not only professional experience. This paper presents a multiple criteria model to support the decision of selecting the use cases that should be tested. © 2009 Springer Berlin Heidelberg.

In this paper, we propose a new method to enhance hidden unit activations of multi-layered networks and to retrain networks imitating enhanced hidden unit activations. One of the most serious problems of multilayered networks consists in difficulty in interpreting final internal representations obtained by learning. Though many methods have been proposed to solve this problem, the problem still remains unsolved. For this problem, we propose a method to enhance hidden unit activations with explicit responses to input patterns. In addition, we propose a new method to retrain networks by imitating the enhanced hidden unit activations. We applied the method to a student survey, a cabinet approval rating estimation and another student survey. In all these problems, we succeeded in producing explicit and interpretable final representations.

In the last few years, Alzheimer's disease has been the most frequent cause of dementia and it is responsible, alone or in association with other diseases, for 50% of the cases in western countries. Dementias are syndromes characterized by a decline in memory and other neuropsychological changes, especially occurring in elderly people and increasing exponentially along the aging process. The main focus of this work is to develop a multicriteria model for aiding in decision making on the diagnosis of Alzheimer's disease by using the Aranau Tool, structured on the Verbal Decision Analysis. In this work, the modeling and evaluation processes were conducted with the aid of a medical expert, bibliographic sources and questionnaires. The questionnaires taken into account were based mainly on patients' neuroimaging tests, and we analyzed wheter or not there were problems in the patients' brain that could be relevant to the diagnosis of Alzheimer's disease. © 2009 Springer Berlin Heidelberg.
