A registration algorithm for on-line measuring the rotational velocity of a table tennis ball

We propose a registration algorithm for on-line measuring the rotational velocity of a table tennis ball in which the nearest neighbor interpolation method is presented to estimate the intensities of the pixels on the later frame by using the information of the previous frame. The conjugate gradient method is used to seek the optimum of the rotational parameter. Experimental results with both a ball rotated by a rotational machine and a flying ball shot from a catapult machine sufficiently demonstrate the effectiveness of the proposed method.
Three-dimensional comprehensive reconstruction and interactive network display

Three-dimensional reconstruction of points cloud is very important in reverse engineering, virtual reality, etc. The commonly used algorithm is based on convex hull. But it causes distortion in direct triangulation region. To tackle this problem, the improved BPA is introduced and it avoids the normal vectors' input and the easily emerged holes for the points cloud with uneven density in the original BPA algorithm. Also, usually only the shape reconstruction of the surface can not perform the color details of the surface. So another important improvement in this paper is to add the color information of each point in the process of the shape reconstruction. In this way, the color of the surface can be obtained by reconstructing each triangle's surface color with interpolation method. At last, to meet the clients' needs, we display the reconstruction result on the web with high interactivity. The experimental results show that the comprehensive reconstruction of the surface has achieved a satisfactory effect.
Generalized integral operator and multivalent functions.

LetA(p) be the class of functions f : f(z) = z + ∑∞ j=1 ajz p+j analytic in the open unit discE. Let, for any integern > −p, fn+p−1(z) = z p (1−z)n+p . We definef (−1) n+p−1(z) by using convolution? asfn+p−1(z) ? f (−1) n+p−1(z) = z (1−z)n+p . A function p, analytic inE with p(0) = 1, is in the classPk(ρ) if ∫ 2π 0 ∣∣∣Rep(z)−ρ p−ρ ∣∣∣ dθ ≤ kπ, wherez = re, k ≥ 2 and 0 ≤ ρ < p. We use the class Pk(ρ) to introduce a new class of multivalent analytic functions and define an integral operator In+p−1(f) = f (−1) n+p−1? f(z) for f(z) belonging to this class. We derive some interesting properties of this generalized integral operator which include inclusion results and radius problems.
Spectral E ciency of Randomly-Spread CDMA over Multipath Rayleigh Fading Channels

In this sequel; we analyze the spectral e ciency sum-rates capacity per temporal degrees of freedom of the uplink randomly-spread CDMA systems with diversity-combining linear multiuser receivers over time-varying frequency-selective multipath Rayleigh fading channels. Basis of the analysis mainly being the asymptotic eigenvalue spectra of the large-dimensional random matrices, the capacity notions considered are the sum-rates ergodic capacity strictly in the Shannon-sense and the sum-rates outage capacity with the later notion being mainly applicable in slowly time-varying coding-delay limited scenarios. Assuming equal-rate/equal-energy identical users and statistically identical channels for each user; the analysis of the closed-form ergodic and outage capacity based spectral e ciency expressions in terms of the key system parameters for both the correlated-waveform vector multi-access channel model with optimum joint-ML multiuser decoding as well as with the linear RAKE; decorrelating and MMSE multiuser receivers followed by suboptimal single-user ML decoding sheds light onto asymptotic system behaviour of large-dimensional channel-coded CDMA systems with linear multiuser receivers over multipath Rayleigh fading channels.
Software-Enabled Investigation in Metaheuristic Power Grid Optimization

Actual developments in power grid research, analysis, and operation are dominated clearly by the strong convergence of electrical engineering with information technology. Hence, new control abilities in power grids come up that revolutionize traditional optimization issues, requiring novel solution methods. At the same time, heuristic algorithms have emerged to be highly capable of handling those new optimization problems. In this work, a simulation-based optimization approach is proposed that enables investigation with metaheuristic algorithms for domain experts, where especially the power engineering point of view gets highlighted. HeuristicLab is demonstrated as a framework for optimization, which facilitates usage and development of optimization algorithms in a way that is attractive not only to computer scientists. From a software point of view, architectural aspects are treated that enable the decoupling of optimization algorithms and problems, which is a basic fundament of the framework. Further, interprocess communication is discussed that enables the interaction of optimization algorithms and simulation problems, and a practical showcase demonstrates the framework's application to real-world power grid optimization issues.
Chandra Observation of the Starburst Galaxy NGC 2146(Poster)

We present six monitoring observations of the starburst galaxy NGC 2146 using the Chandra X-ray Observatory. We detected 67 point sources in the field of view of the ACIS-S detector. Six of these sources were Ultra-Luminous X-ray Sources, the brightest of which had a luminosity of 5 × 10 39 ergs −1 . One of them, with a luminosity of ∼ 1 ×10 39 ergs −1 , is coincident with the dynamical center location, which may be a low-luminosity active galactic nucleus. We have produced a table where the positions and main characteristics of the detected sources are reported. A comparison between the positions of the X-ray sources and those detected in NIR or radio indicates no definite counterpart. We have derived a log N–logS relation and a luminosity function. The luminosity function has a slope of 0.71 above a detection limit, which is similar to those found in other starburst galaxies. Diffuse emissions were detected in both soft (0.5–2.0keV) and hard (2.0–10.0keV) energy bands. The spectra of the diffuse component were fitted with two (hard and soft) components. The hard power-law component, with a luminosity of ∼4 ×10 39 ergs −1 , is likely to have originated by unresolved point sources.
Enhancing the culturalcompetencyof prospectiveleaders via a studyabroad experience

The purpose of this investigation was to determine whether an experiential learning opportunity, specifically a study tour experience, would improve the cultural intelligence of prospective educational leaders and would challenge them to expand their own cultural understanding and behavior. Several prospective leaders who enrolled in a graduate program in Educational Leadership volunteered to attend a study abroad program that was intended, in part, to enhance their cultural competence. They were then asked to complete a survey that measured the four domains of cultural intelligence, namely metacognition, cognition, motivation and behavior. They were also asked to respond to prompts about how the experiential learning experience impacted their own cultural understanding and behavior. The results indicated that the study tour participants were cognizant of their cultural intelligence and that they compared and contrasted the norms of their own culture and those of the study tour country. In essence, participants acquired substantial cultural intelligence and reflected on how their leadership behavior should change to meet the needs of others.
A statistical approach to analyse positional dependencies in protein domains

Motivation: Protein domains are usually identified by conserved regions in the primary amino acid structure. Protein functions are dependent on the 3-dimensional structure and the biochemical properties of the amino acids. 3-Dimensional structures are stabilized by interactions between amino acids which are not adjacent in the primary structure. To preserve the structure, even if certain residues of the sequence are mutated, similar interactions must be possible. This property should be reflected by dependencies between residues of positions taking part in an interaction. We use a statistical approach to identify such positional dependencies in aligned protein sequences of the death domain family and the homeodomain. Results: We identified a 12 amino acid region with high correlations in the death domain and the CARD. Most of known mutations in death domain family members and the homeodomain showed a strong correlation with other positions in the protein. Contact: schuler@informatik.uni-ulm.de
Classifications Of Credit Cardholder Behavior By Using Fuzzy Linear Programming

Behavior analysis of credit cardholders is one of the main research topics in credit card portfolio management. Usually, the cardholder's behavior, especially bankruptcy, is measured by a score of aggregate attributes that describe cardholder's spending history. In real-life practice, statistics and neural networks are the major players to calculate such a score system for prediction. Recently, various multiple linear programming-based classification methods have been promoted for analyzing credit cardholders' behaviors. As a continuation of this research direction, this paper proposes a heuristic classification method by using the fuzzy linear programming (FLP) to discover the bankruptcy patterns of credit cardholders. Instead of identifying a compromise solution for the separation of credit cardholder behaviors, this approach classifies the credit cardholder behaviors by seeking a fuzzy (satisfying) solution obtained from a fuzzy linear program. In this paper, a real-life credit database from a major US bank is used for empirical study which is compared with the results of known multiple linear programming approaches.
An Investigation into the feasibility of Human Facial Modeling

1. Abstract In this paper, virtual videoconferencing is investigated. The goal of the project is to develop a cheap, realistic yet real-time 3D face-modeling tool using a number of camera feeds. Bandwidth utilisation can then be minimised by transferring only the actual model (and subsequently, changes to the model) of the actor's face. Using a virtual reality system, reconstruction of a human face is performed and transmitted, thereby reducing bandwidth requirements. The modeling process is discussed, with results.
Energy-aware partitioning of tasks onto a heterogeneous multi-core platform

Modern multicore processors for the embedded market are often heterogeneous in nature. One feature often available are multiple sleep states with varying transition cost for entering and leaving said sleep states. This research effort explores the energy efficient task-mapping on such a heterogeneous multicore platform to reduce overall energy consumption of the system. This is performed in the context of a partitioned scheduling approach and a realistic power model, which improves over some of the simplifying assumptions often made in the state-of-the-art. The developed heuristic consists of two phases, in the first phase, tasks are allocated to minimise their active energy consumption, while the second phase trades off a higher active energy consumption for an increased ability to exploit savings through more efficient sleep states. Extensive simulations demonstrate the effectiveness of the approach.
Task-irrelevant perceptual expertise University of Hong Kong , Hong Kong

Perceptual learning (PL) and perceptual expertise (PE) are two fields of visual training studies that investigate how practice improves visual performance. However, previous research suggests that PL can be acquired in a task-irrelevant manner while PE cannot and that PL is highly specific to the training objects and conditions while PE generalizes. These differences are difficult to interpret since PL and PE studies tend to differ on multiple dimensions. We designed a training study with novel objects to compare PL and PE while varying only the training task, such that the training objects, visual field, training duration, and type of learning assessment were kept constant. Manipulations of the training task sufficed to produce the standard effects obtained in PE and PL. In contrast to prior studies, we demonstrated that some degree of PE can be acquired in a task-irrelevant manner, similar to PL. Task-irrelevant PE resulted in similar shape matching ability compared to the directly trained PE. In addition, learning in both PE and PL generalizes to different untrained conditions, which does not support the idea that PE generalizes while PL is specific. Degrees of generalization can be explained by considering the psychological space of the stimuli used for training and the test of transfer.
The apparent inversion time for optimal delayed enhancement magnetic resonance imaging differs between the right and left ventricles.

BACKGROUND Delayed post-contrast magnetic resonance (MR) imaging involves suppression of signal from myocardium using inversion times (TI) between 150-225 ms, when the myocardium appears dark and fibrotic scar appears bright. We noticed that at a TI optimized for signal suppression of the left ventricle (LV), the right ventricle (RV) appeared brighter. PURPOSE The purpose of this study was to evaluate the TI for signal suppression in RV compared to LV, and to try and identify the cause of this observation. Methods. We studied 31 patients (ages ranged from 17-79 years, 11 females) who had an MR scan on a 1.5 T GE scanner. Delayed post-contrast short-axis images were obtained 20 minutes after injection of 0.2 mmol/kg of intravenous gadolinium chelate. TI optimization was performed by acquiring a range of TI times within a single breath hold, in increments of 25 msec. The TI time that resulted in lowest signal for the RV arid LV was recorded. RESULTS With the imaging sequence employed, the TI leading to LV signal suppression ranged from 150-225 ms. At the TI that resulted in LV signal suppression, the corrected signal from the RV was significantly higher as compared to the LV (29 +/- 13 au vs. 15 +/- 8 au, p < 0.001). The findings were similar using only the body coil. The TI required to suppress the RV was usually < or =150 msec. The observation persisted before and after gadolinium infusion. CONCLUSION The TI for myocardial signal suppression appears to be different between LV and RV. Potential mechanisms include partial volume averaging with fat or blood pool (related to increased trabeculation) in the RV. Alternatively, increased blood pool signal (within Thebesian veins or arterioluminal communications) in RV compared to LV leads to altered TI times due to similar partial volume effects.
Generic identifiers for ID/locator split internetworking

We have developed an identifier/locator split network architecture that uses separate sets of entities for identifiers and locators in order to eliminate certain problems that will arise if conventional Internet architecture, which uses Internet Protocol addresses as both node identifiers and locators, is used in the new generation network, which will have a very large number of heterogeneous devices. If conventional architecture is used, there will be particular problems in several areas, including mobility and multihoming management, security and privacy, scalable routing, and traffic engineering. In our architecture, identifiers are used in the application and transport layers for identifying nodes, and locators are used in the network layer for locating nodes in the network topology. Nodes can change locators at any time without disrupting ongoing communication sessions, thus supporting efficient mobility and multihoming. The identifiers, which are independent of internetworking technology, are compatible with existing and future locators and routing systems.
Send Orders of Reprints at Reprints@benthamscience.org Risk of Infectious Diseases in Patients with Copd

In this paper, we review data on the risk of infectious diseases in chronic obstructive pulmonary disease (COPD), including the efficacy of antibiotics for prevention and treatment of acute COPD exacerbations, with a focus on more recent studies. Studies indicate that immunological mechanisms in COPD are impaired, leading to increased susceptibility to infection. Exacerbations are often infectious in origin (viral and/or bacterial) although pathogens may also be present in the lungs of person with stable COPD. The detailed mechanisms of exacerbations remain under investigation. Despite great variations in design and operational definitions of outcome, studies consistently find that patients with COPD are at an increased risk of respiratory infections. Patients with COPD do not appear to be at an increased risk of infections outside the respiratory system, but only a small number of studies have addressed this. The role of antibiotics in the management of acute exacerbations of COPD is disputed. However, findings from recent studies suggest that antibiotics are effective, although primarily in patients admitted to the hospital, thus representing patients with more severe exacerbations. Still, the question of antibiotic efficacy for different clinically well-defined subgroups of COPD exacerbation as well as the choice of the most appropriate antibiotic for these subgroups is uncertain. Antibiotics may also be efficacious in exacerbation prevention. Recent studies on the efficacy of macrolides for the prevention of COPD exacerbations demonstrated promising results. Nevertheless, questions on the risk-benefit ratio of macrolides, efficacy in subgroups of COPD patients, and long-term effects remain unanswered.
Multi-kernel construction of polar codes

We propose a generalized construction for binary polar codes based on mixing multiple kernels of different sizes in order to construct polar codes of block lengths that are not only powers of integers. This results in a multi-kernel polar code with very good performance while the encoding complexity remains low and the decoding follows the same general structure as for the original Arikan polar codes. The construction provides numerous practical advantages as more code lengths can be achieved without puncturing or shortening. We observe numerically that the error-rate performance of our construction outperforms state-of-the-art constructions using puncturing methods.
Correlation Between Pain, Fear of Falling and Disability in Low Back Pain

Objective To ascertain if there is a correlation between low back pain (LBP), fear of falling, and disability so that the patients with LBP are aware of the fact that other problems may occur with LBP. Hence, steps can be taken for decreasing the fear of falling and disability in order to improve the condition of patients. Methods A sample size of 100 patients with low back pain, with a range of ages from 40 to 73 years, participated in the study. The Falls Efficacy Scale was used to assess the fear of falling and the Oswestry Disability Index was used to assess the disability and pain in LBP individuals. Results The Pearson correlation analysis signifies the relationship between pain, fear of falling, and disability in LBP. Conclusion First, LBP increases the fear of falling. Second, LBP can result in a person becoming disabled. Third, the fear of falling and disability are correlated with each other.
Youth Reports of Parental Strategies and Sense of Coherence: Are Experiences of Being Victim of Physical Abuse Reflected?

This article explores adolescent’s reports of parental strategies and sense of coherence (SOC). Building on the suggested impact of child physical abuse, this study compares reports from a group of physically abused youth and a group of non-abused youth. Independent t-test, correlations and hierarchical linear regression analysis were computed. Findings indicate that parents’ use of corporal punishment could affect how youth report their parent’s parental strategies. Physically abused youth report less parental involvement and positive parenting as well as more inconsistent parenting than non-abused youth. Furthermore, physically abused youth report a significant lower SOC than non-abused youth. Being a victim of physical abuse had a unique contribution on SOC, even after controlling for other parental strategies. Taken together, the results suggest that child physical abuse affects both the youth’s inner SOC as well as their reports of parental strategies in several ways. Implications for practice are discussed in this article.
An Integrated Architecture for Remote Healthcare Monitoring

Remote healthcare monitoring has attracted the interest of many research projects during last years. The need to address the issue of ageing population has lead to the exploitation of modern communication and software technologies in this domain too. This is instigated by related technological evolutions such as the evolutions in sensor networks which can now support self organization. This paper presents the INCASA architecture that provides advances towards mainly two directions. To start with, by using the appropriate middleware, it manages to transform the network of devices to a network of services following a Service Oriented Architecture. In this way, it turns the implementation of applications (e.g. clinical applications) on top of the middleware to be easy and efficient. Furthermore, INCASA architecture provides an integrated solution for profiling user habits. This is particularly important in case of elderly people who tend to follow daily activities in a repeating manner. In the proposed architecture, the procedure of modeling user habits is the necessary step in order to generate alert actions in case of divergence.
New Strategies in Hepatocellular Carcinoma: Genomic Prognostic Markers

Accurate prognosis prediction in oncology is critical. In patients with hepatocellular carcinoma (HCC), unlike most solid tumors, the coexistence of two life-threatening conditions, cancer and cirrhosis, makes prognostic assessments difficult. Despite the usefulness of clinical staging systems for HCC in routine clinical decision making (e.g., Barcelona-Clinic Liver Cancer algorithm), there is still a need to refine and complement outcome predictions. Recent data suggest the ability of gene signatures from the tumor (e.g., EpCAM signature) and adjacent tissue (e.g., poor-survival signature) to predict outcome in HCC (either recurrence or overall survival), although independent external validation is still required. In addition, novel information is being produced by alternative genomic sources such as microRNA (miRNA; e.g., miR-26a) or epigenomics, areas in which promising preliminary data are thoroughly explored. Prognostic models need to contemplate the impact of liver dysfunction and risk of subsequent de novo tumors in a patient’s life expectancy. The challenge for the future is to precisely depict genomic predictors (e.g., gene signatures, miRNA, or epigenetic biomarkers) at each stage of the disease and their specific influence to determine patient prognosis.

On the Adequacy of Expert Teachers: From Practical Convenience to Psychological Reality

This literature review examined approximately 10000 titles in five representative journals in education. It is conducted at two levels. Section A identified the preferred terms and metaphors to describe teachers at different expertise levels. Results indicated a great inconsistency in terms of terminology as well as definition of the same terms or metaphors in different journals, with a lot of them being suggestive and poetic. Section B started with the two most frequent terms, "expert" & "experienced", and put thirty two empirical studies into content analysis to uncover how their respective samples were operationally defined and selected. Findings showed both terms were constantly under-represented and there was a lack of dependable agreed-upon definition of "experienced and expert". It is argued our limitations in educational knowledge could be partly attributed to such poor conceptualizations, imprecise operationalization, and ‘reductive bias ‘of researchers.
