A Web community-based video retrieval method using canonical correlation analysis

This paper presents a Web community-based video retrieval method using canonical correlation analysis (CCA). In the proposed method, two novel approaches are introduced into the retrieval scheme of video materials on the Web. First, the CCA is applied to three kinds of video features, visual and audio features of video materials and textual features obtained fromWeb pages containing those video materials. This approach provides a solution of problems of traditional methods of not being able to calculate similarities between different kinds of video features. Furthermore, from the obtained similarities and link relationships of Web pages, a new adjacency matrix is defined, and link analysis can be applied to this matrix. Then, the Web communities of the video materials whose topics are similar to each other can be automatically extracted based on their features. Therefore, by ranking the video materials in the obtained Web community, accurate video retrieval can be realized.
Speed up of test generation using high-level primitives

A general methodology to speed up the test generation process for combinational circuits with high-level primitives is proposed. The technique is able to handle circuits in a hierarchical fashion, treats the signal at a bit-vector level rather than the bit level and takes advantage of the complex operations that are available in the computer system. The technique has been implemented and the results are presented for five circuits. It is shown that by using the high-level primitives a significant speed-up and significant reduction in storage requirement are achieved. More importantly, the reduction in storage size permits test generation for very large circuits. It is clear that use of high-level primitives is more efficient than use of low-level primitives in test generation. A dependency-directed backtracking mechanism is also present which reduces the number of backtracks. The technique presented is complete, permits test vector generation for a broad class of large circuits with complex primitives, and accommodates a very general fault model. <<ETX>>
A Compositional Framework for End-to-End Path Delay Calculation of Automotive Systems under Different Path Semantics

While the real-time systems community has developed very valuable approaches to timing and scheduling analysis for processors and buses over the last four decades, another very relevant issue has received only limited attention: end-to-end timing. Most of the known work poses restrictions on speciﬁc task activation and communication mechanisms, e.g. unbounded FIFO queues along event-triggered paths. In automotive systems, however, register buffers and periodic sampling are far more common. In this paper, we present a formal framework for the calculation of end-to-end latencies in multi-rate, register-based systems. We show that in systems with sampling, analysis must distinguish between different "meanings" of end-to-end timing. For instance, control engineers are mostly concerned with the "maximum age of data", i.e. the worst-case timing of the latest possible signal. In body electronics, the "ﬁrst reaction" is key, i.e. worst-case timing of the earliest possible signal. Because the analysis of either case can be different, a clear distinction is mandatory. This paper gives examples and introduces the notion of such end-to-end timing semantics, thereby considering the speciﬁc mechanisms and effects typically found in automotive execution platforms such as over- and under-sampling and jitter.
Introducing topological attributes for objective-based visualization of simulated datasets

Recent development in the design of multi-dimensional transfer functions allows us to automatically generate comprehensible visualization images of given volumes by taking into account local features such as differentials and curvatures. However, especially when visualizing volumes obtained by scientific simulations, observers usually exploit their knowledge about the simulation settings as the clues to the effective control of visualization parameters for their own specific purposes. This paper therefore presents an objective-based framework for visualizing simulated volume datasets by introducing a new set of topological attributes. These topological attributes are calculated from the level-set graph of a given volume dataset, and thus differ from the conventional local attributes in that they also illuminate the global structure of the volume. The present framework provides a systematic means of emphasizing the underlying volume features, such as nested structures of isosurfaces, configuration of isosurface trajectories, and transitions of isosurface's topological type. Several combinations of the topological attributes together with the associated transfer function designs are devised and applied to real simulated datasets in order to demonstrate the feasibility of the present framework.
III-V compound semiconductor nanostructures on silicon: epitaxial growth, properties, and applications in light emitting diodes and lasers

Significant developments have occurred in the area of III-V compound semiconductor nanostructures. The scope of developments includes quantum dots and nanowires epitaxially grown on Si substrates, as well as their applications in light emitting diodes and lasers. Such nanoscale heterostructures exhibit remarkable structural, electrical, and optical properties. The highly effective lateral stress relaxation, due to the presence of facet edges and free surfaces, enables the achievement of nearly defect-free III-V nanoscale heterostructures directly on Si, in spite of the large lattice mismatches and the surface incompatibility. With the incorporation of multiple quantum dot layers as highly effective three-dimensional dislocation filters, self-organized quantum dot lasers monolithically grown on Si exhibit, for the first time, relatively low threshold current (Jth = 900 A/cm2) and very high temperature stability (T0 = 244 K). III-V semiconductor nanowire light emitting diodes on Si, with emission wavelengths from UV to near-infrared, have also been demonstrated.
The Effects of Changing Attention and Context in an Awake Offline Processing Period on Visual Long-Term Memory

There is accumulating evidence that sleep as well as awake offline processing is important for the transformation of new experiences into long-term memory (LTM). Yet much remains to be understood about how various cognitive factors influence the efficiency of awake offline processing. In the present study we investigated how changes in attention and context in the immediate period after exposure to new visual information influences LTM consolidation. After presentation of multiple naturalistic scenes within a working memory paradigm, recognition was assessed 30 min and 24 h later in three groups of subjects. One group of subjects engaged in a focused attention task [the Revised Attentional Network Task (R-ANT)] in the 30 min after exposure to the scenes. Another group of subjects remained in the testing room during the 30 min after scene exposure and engaged in no goal- or task-directed activities. A third group of subjects left the testing room and returned 30 min later. A signal detection analysis revealed no significant differences among the three groups in hits, false alarms, or sensitivity on the 30-min recognition task. At the 24-h recognition test, the group that performed the R-ANT made significantly fewer hits compared to the group that left the testing room and did not perform the attention ask. The group that performed the R-ANT and the group that remained in the testing room during the 30-min post-exposure interval made significantly fewer false alarms on the 24-h recognition test compared to the group that left the testing room. The group that stayed in the testing room and engaged in no goal- or task-directed activities exhibited significantly higher sensitivity (d') compared to the group that left the testing room and the group that performed the R-ANT task. Staying in the same context after exposure to new information and resting quietly with minimal engagement of attention results in the best ability to distinguish old from novel visual stimuli after 24 h. These findings suggest that changes in attentional demands and context during an immediate post-exposure offline processing interval modulate visual memory consolidation in a subtle but significant manner.
Specifying Organizational Policies and Individual Preferences for Human-Software Interaction

Current manned space operations employ policies and protocols to specify an etiquette for human-human interaction. This space operations etiquette presumes that operations are conducted synchronously from a few centralized locations - a control center or space vehicle. The availability of automated control software, portable computing platforms, and wireless communication makes it possible for distributed groups of humans and software agents to conduct some space operations remotely and asynchronously. The space operations etiquette must be adapted to address the challenges that arise when changing to teams of distributed agents. We are investigating intelligent support agents for crew and ground personnel that implement an etiquette for notification and alerting, which is an essential part of the space operations etiquette. Our approach differs from previous work on notification and alerting because it focuses on meeting the needs of an organization rather than the needs of an individual. In this paper we describe our etiquette for remote space operations and our approach for implementing context sensitive notification.
A High Spectral Resolution Atlas of Comet 122 P / de Vico

On 3 and 4 October, 1995, we obtained high spectral resolving power (R= λ/∆λ = 60, 000) observations of comet 122P/de Vico using the 2DCoude cross-dispersed echelle spectrograph on the 2.7-m telescope of McDonald Observatory. The spectra cover the wavelength range from 3830Å– 10192Å. The spectra from 3830–5776Å are continuous; from 5777–10192Å there are increasing interorder gaps. The comet was at a heliocentric distance of 0.66 au and a geocentric distance of 1.0au. Comet de Vico has a very high gas-to-dust ratio and the spectra have excellent signal/noise. These two factors combined to yield spectra with a large number of emission lines. We have collected laboratory molecular line lists and have used these line lists in order to identify as many of the detected lines as possible. We have identified 12,219 emission lines and have located another 4,055 lines which we cannot identify. We present representative spectra and identifications along with a description of our plans to make these spectra and identifications available to the community. This atlas should prove a valuable tool for future studies of comets.
CLAUSE-LEVEL RELATIONSHIP ANALYSIS IN THE TANKA SYSTEM

Knowledge acquisition from text is often attempted in the presence of large amounts of pre-coded domain knowledge. Seeding a system with such knowledge is often a huge knowledge acquisition effort in itself. Breaking this circle requires a text processing system that relies on little a priori semantic information. In the absence of such knowledge, processing must rely on available information, such as surface syntax. Semantic analysis will consist of determining the semantic relationships between the various surface-syntactic constituents in the sentence. This report describes the design and implementation of a system that interactively interprets semantic relationships between clauses. The ClauseLevel Relationship Analyzer inspects the parse trees produced by a domainindependent parser for syntactic features that can be used to determine what kinds of semantic relationships exist between clauses. The system is designed to require as little a priori semantic knowledge as possible. This document offers a set of semantic labels appropriate to syntactically connected clauses and a description of the theory behind assigning these labels to particular inputs. It also presents elements of the implementation of the Clause-Level Relationship Analyzer and looks at its performance.
Localization of active sites along the myelinated goldfish Mauthner axon: morphological and pharmacological evidence for saltatory conduction

njections of Lucifer Yellow (LY) and horseradish peroxidase (HRP) were made within the myelin sheath of the goldfish Mauthner axon to determine the domains of individual oligodendrocytes. Long segments of the myelin sheath were stained with both markers. The lengths and locations of these sheath segments were analyzed in whole mount preparations (LY) or in reconstructions of serial vibratome sections (HRP). The termination sites of individual myelin sheaths, relative to gross anatomical landmarks of the brain, were consistent within and between all fish studied. In particular, the average locations of the termination sites were separated by 2.2 to 2.6 mm and corresponded to the brain regions where active site foci have been previously localized electrophysiologically. Individual sheath segments generally spanned the entire distance between adjacent active sites. The node-internode- node structure of the Mauthner axon that is suggested by these findings was further tested by ejecting tetrodotoxin (TTX) at various discrete rostral-caudal locations just outside the fiber. Large all-or-nothing components of the antidromic action potential were rapidly blocked (within seconds) only when the TTX ejections were made within a few hundred micrometers of the active site foci. The amplitudes of these blocked components are also consistent with predictions based upon previous electrophysiological analyses which demonstrated an active site spacing of 2.2 to 2.6 mm, a space constant of 5.0 mm, and a safety factor of 6 for impulse propagation. It is concluded from these morphological, pharmacological, and electrophysiological observations that the Mauthner axon possesses nodes separated by 2.2 to 2.6 mm and that a single oligodendrocyte spans an internodal region. Although nodal ultrastructure remains to be described, these results rule out the possibility that each of the short (approximately 50 micron), closely spaced (average separation = 155 micron) axon collaterals is a site of action current production.
A software tool to relate technical performance to user experience in a mobile context

Users in todaypsilas mobile ICT environment are confronted with more and more innovations and an ever increasing technical quality, which makes them more demanding and harder to please. It is often hard to measure and to predict the user experience during service consumption. This is nevertheless a very important dimension that should be taken into account while developing applications or frameworks. In this paper we demonstrate a software tool that is integrated in a wireless living lab environment in order to validate and quantify actual user experience. The methodology to assess the user experience combines both technological and social assets. User experience of a Wineguide application on a PDA is related to signal strength, monitored during usage of the applications. Higher signal strengths correspond with a better experience (e.g. speed). Finally, difference in the experience among users will be discussed.
Low Reynolds Number Airfoil Design Lecture Notes

An approach to low Reynolds number airfoil design is described, and several example design cases are presented and discussed. The overall approach involves using the inverse method PROFOIL for design and XFOIL for analysis. Validation of these methods and the low Reynolds number airfoil design philosophy is supported by UIUC wind tunnel experiments. These notes derive largely from four prior publications of the author (see Refs. 1–4) and the contributions of the respective co-authors are gratefully acknowledged.
Developmental cascades of peer rejection, social information processing biases, and aggression during middle childhood

Abstract This study tested a developmental cascade model of peer rejection, social information processing (SIP), and aggression using data from 585 children assessed at 12 time points from kindergarten through Grade 3. Peer rejection had direct effects on subsequent SIP problems and aggression. SIP had direct effects on subsequent peer rejection and aggression. Aggression had direct effects on subsequent peer rejection. Each construct also had indirect effects on each of the other constructs. These findings advance the literature beyond a simple mediation approach by demonstrating how each construct effects changes in the others in a snowballing cycle over time. The progressions of SIP problems and aggression cascaded through lower liking, and both better SIP skills and lower aggression facilitated the progress of social preference. Findings are discussed in terms of the dynamic, developmental relations among social environments, cognitions, and behavioral adjustment.
Prioritizing test cases for resource constraint environments using historical test case performance data

Regression testing has been widely used to assure the acquirement of appropriate quality through several versions of a software program. Regression testing, however, is too expensive in that, it requires many test case executions and a large number of test cases. To provide the missing flexibility, researchers introduced prioritization techniques. The aim in this paper has been to prioritize test cases during software regression test. To achieve this, a new equation is presented. The proposed equation considers historical effectiveness of the test cases in fault detection, each test case's execution history in regression test and finally the last priority assigned to the test case. The results of applying the proposed equation to compute the priority of regression test cases for two benchmarks, known as Siemens suite and Space program, demonstrate the relatively faster fault detection in resource and time constrained environments.
Measurement of anal sphincter muscles: endoanal US, endoanal MR imaging, or phased-array MR imaging? A study with healthy volunteers.

PURPOSE To compare endoanal ultrasonography (US), endoanal magnetic resonance (MR) imaging, and phased-array MR imaging for anal sphincter muscle measurement. MATERIALS AND METHODS Sixty healthy volunteers underwent 1.5-T phased-array MR, endoanal MR, and endoanal US examinations. Sphincter muscle thicknesses were measured. Measurement reliability was analyzed, and correlations among the imaging methods were calculated. Multivariate analysis was performed to assess the influence of age, weight, height, sex, parity, and obstetric trauma on sphincter dimensions. RESULTS Both MR methods had good reliability for measurements of all sphincter components, whereas endoanal US was reliable for internal sphincter measurement only. There was little correlation between the techniques, except between the two MR techniques, with a strong correlation for total sphincter and perineal body thickness. The internal sphincter thickened significantly (P =.002) with age at endoanal US and endoanal MR imaging but not at phased-array MR imaging. There were small sex-based differences in sphincter muscle measurements at phased-array MR imaging only. CONCLUSION Endoanal US enables reliable measurement of only internal sphincter thickness, whereas both MR imaging methods enable reliable measurement of all sphincter components. Sphincter measurement with phased-array MR imaging is as reliable as that with endoanal MR imaging.
Bax-induced Cytochrome C Release from Mitochondria Is Independent of the Permeability Transition Pore but Highly Dependent on Mg2+ Ions

Bcl-2 family members either promote or repress programmed cell death. Bax, a death-promoting member, is a pore-forming, mitochondria-associated protein whose mechanism of action is still unknown. During apoptosis, cytochrome C is released from the mitochondria into the cytosol where it binds to APAF-1, a mammalian homologue of Ced-4, and participates in the activation of caspases. The release of cytochrome C has been postulated to be a consequence of the opening of the mitochondrial permeability transition pore (PTP). We now report that Bax is sufficient to trigger the release of cytochrome C from isolated mitochondria. This pathway is distinct from the previously described calcium-inducible, cyclosporin A–sensitive PTP. Rather, the cytochrome C release induced by Bax is facilitated by Mg2+ and cannot be blocked by PTP inhibitors. These results strongly suggest the existence of two distinct mechanisms leading to cytochrome C release: one stimulated by calcium and inhibited by cyclosporin A, the other Bax dependent, Mg2+ sensitive but cyclosporin insensitive.
Analysis of Facebook Friends Using Disclosure Level

Social Networking Services (SNSes), such as Facebook and Twitter, provide a communication platform that easily communicates with a family, close friends, acquaintances and strangers. On the other hands, SNS users often unintentionally post a message on SNSes, including one's own sensitive information, and is revealed to other users. As a result, an SNS user can lose friend, or even a job. Moreover offhand posts can result in unforeseen problems. In order to prevent privacy leaks to SNSes, we defined an objective classification-table of invasion of privacy for SNSes that will be based on classification according to contents of information, which should be kept private, and disclosure level. We also proposed a method that uses the classification table to provide settings for access control that prevent privacy leaks. In this paper, as a realization of this method, we developed a prototype system that adaptive disclosure control system on Facebook based on detection of sensitive information leaks and friends classified according to the disclosure level.
Reach out and touch me: effects of four distinct haptic technologies on affective touch in virtual reality

Virtual reality presents an extraordinary platform for multimodal communication. Haptic technologies have been shown to provide an important contribution to this by facilitating co-presence and allowing affective communication. However, the findings of the affective influences rely on studies that have used myriad different types of haptic technology, making it likely that some forms of tactile feedback are more efficient in communicating emotions than others. To find out whether this is true and which haptic technologies are most effective, we measured user experience during a communication scenario featuring an affective agent and interpersonal touch in virtual reality. Interpersonal touch was simulated using two types of vibrotactile actuators and two types of force feedback mechanisms. Self-reports of subjective experience of the agent’s touch and emotions were obtained. The results revealed that, regardless of the agent’s expression, force feedback actuators were rated as more natural and resulted in greater emotional interdependence and a stronger sense of co-presence than vibrotactile touch.
