Fabrication of Carbon Nanotubes and Investigating the Characteristics

nanotubes (CNT) are the fantastic nano-material which exhibits a very low thermal expansion and high current capability. It has a wide variety of methods for synthesis. One of the most reliable and best suited is Arc Discharge method. Multi walled CNT (MWCNT) are synthesized in an experimental setup. Soot deposited is in mixture form of nanoparticles and hence it is purified and MWCNT are separated and collected. XRD analysis and TEM images are taken for CNT. MWCNT are coated on the silica substrate through DIP coating. Dispersion of CNT is handled and the resistivity and morphology of cnt dip coated are studied. The change in resistivity is determined by the graph plotted through Four Point Probe method. Investigation concludes that the MWCNT developed is suitable for contacts in transistors and miniature sensors for fabrication due to its low resistivity.
Sensor Fault Diagnosis of Wind Turbines for Fault Tolerant

This paper aims at the blade root moment sensor fault detection and isolation issue. The underlying problem is crucial to the successful application of the individual pitch control system which plays a key role for reducing the blade loads of large offshore wind turbines. In this paper, a wind turbine model is built based on the closed loop identification technique, where the wind dynamics is included in the model. The fault detection issue are investigated based on the residual generated by Kalman filter. The additive faults and multiplicative faults are investigated respectively. For the additive fault case, the mean value change detection of the residual and the generalized likelihood ratio test are utilized respectively. On the other hand, the multiplicative fault is handled by the variance change detection of the residuals. The fault isolation issue is proceeded with the help of dual sensor redundancy. Simulation results show that the proposed approach can be successfully applied to the underlying issue.
School Change: A Craft-Derived and Research-Based Strategy

It is widely believed that research findings are not used as guides to school and classroom practice, Many reasons have been advanced for this condition, such as the reluctance of researchers to communicate their findings to constituent groups other than their research colleagues, the rigidity of school persons in terms of reconceptualizing the role of teacher or the organization of schools, the “closed-system” nature of many school settings, the lack of rewards for changing behavior, and the apparent lack of logical connections between craft and research findings. ’ In short, it appears that the link between the research findings and the potential users of those findings has not developed to any sufficient degree. The study reported here was an attempt to develop such a link. The following pages contain a description of an effort to alter staff-developer, teacher, and pupil behaviors. *
Temporal dynamics of prokaryotic communities in the marine sponge Sarcotragus spinosulus

In spite of their putative relevance to host functioning, in‐depth knowledge of sponge microbiome stability over time is scarce. This study tackles the temporal maintenance of bacterial and archaeal assemblages in the model host Sarcotragus spinosulus along three successive years. Prokaryotic communities were profiled by polymerase chain reaction‐denaturing gradient gel electrophoresis (PCR‐DGGE) and 454‐pyrosequencing of S. spinosulus‐derived 16S rRNA gene amplicons. Prevailing bacterial phyla were Actinobacteria, Acidobacteria, Proteobacteria, Poribacteria, PAUC34f, Chloroflexi and Bacteroidetes, with Bacteroidetes, Chloroflexi and Poribacteria showing different abundances over the years. At the approximate species level (operational taxonomic units, OTUs, defined at 97% sequence similarity), no major changes in bacterial richness and composition were found through time. Nearly 50% of all detected bacterial symbionts (96 in 205 OTUs) were recovered from all sampling years, whereas a taxonomically equivalent community of less dominant bacteria characterized the transient sponge microbiota. Despite the evidence for temporal symbiont maintenance, an intriguing cumulative degree of variation between individuals was unravelled, with all the surveyed sponge specimens sharing only 27 bacterial OTUs. Archaeal communities were dominated by one single symbiont of the candidate genus Nitrosopumilus (Thaumarchaeota), known for its ability to aerobically oxidize ammonia to nitrite. Only few bacterial ammonia oxidizers consistently occurred in S. spinosulus across the years as documented by PCR‐DGGE fingerprinting. In conclusion, prokaryotic symbionts of S. spinosulus display a state of dynamic stability shaped by the interplay between the maintenance of dominant players and turnover of less prevalent community members, in time and across host individuals, with no apparent consequences to holobiont functioning.
Examination of Clinical and Cognitive Insight in Acute Schizophrenia Patients

Lack of insight or awareness of illness is a hallmark feature of schizophrenic illness and has become an increasingly important area of investigation. Although clinical insight focuses on awareness of illness factors, the concept of cognitive insight focuses on the cognitive processes involved in correcting erroneous judgments and certainty about mistaken judgments. The present study was aimed at further investigating the clinical utility and the statistical coherence of the Beck Cognitive Insight Scale (BCIS) (Beck et al., 2004) in acute schizoaffective and schizophrenia (SZ) patients. The present study examined the internal consistency of the scale, as well as its discriminative and predictive validity relative to a well-established traditional measure of clinical insight in a sample of 50 DSM-IV diagnosed SZ patients, presenting for acute inpatient treatment. The BCIS was found to be an internally consistent and a coherent measure of cognitive insight. The BCIS was unassociated with clinical insight, indicating the 2 constructs share little empirical overlap. Cognitive insight was found to be inversely associated with patients’ severity of autistic preoccupation symptoms such that those individuals with more cognitive insight, exhibited fewer autistic/cognitive symptoms. Patients’ clinical insight, however, was found to be inversely associated specifically with patients’ severity of depression. Additionally, clinical insight was also found to be more impaired in patients residing in nursing home environments relative to their counterparts living in less restrictive settings when outside the hospital. Results are discussed in terms of the relationship between clinical and cognitive insight constructs to SZ symptom domains.
Design of a Tubular Linear Oscillating Motor With a Novel Compound Halbach Magnet Array

A linear oscillating motor provides short-stroke reciprocating motion directly and is widely used in linear actuation systems. However, with the increase of actuation frequency to achieve high power density, the large mover mass becomes the main obstacle. Existing solutions either sacrifice force density or increase fabrication difficulties for high dynamic performance. In this paper, a novel compound Halbach magnet array is proposed for moving-magnet tubular linear oscillating motor in high-frequency applications. In this structure, dual-layer magnets are utilized for better self-shielding effects. Thus, the conventional back-iron in the mover is no longer needed, which contributes to both high force density and low mover mass simultaneously. The analytical model is first set up based on harmonic function method. Then, finite-element-method results are used for validation and comparison with conventional designs. Based on the verified model, electromagnetic structure optimization is conducted, which leads to the prototype structure. Finally, experimental results on electromagnetic performance are provided for validation of the proposed motor with a novel magnet array.
Automated analysis of time-lapse fluorescence microscopy images: from live cell images to intracellular foci

MOTIVATION Complete, accurate and reproducible analysis of intracellular foci from fluorescence microscopy image sequences of live cells requires full automation of all processing steps involved: cell segmentation and tracking followed by foci segmentation and pattern analysis. Integrated systems for this purpose are lacking. RESULTS Extending our previous work in cell segmentation and tracking, we developed a new system for performing fully automated analysis of fluorescent foci in single cells. The system was validated by applying it to two common tasks: intracellular foci counting (in DNA damage repair experiments) and cell-phase identification based on foci pattern analysis (in DNA replication experiments). Experimental results show that the system performs comparably to expert human observers. Thus, it may replace tedious manual analyses for the considered tasks, and enables high-content screening. AVAILABILITY AND IMPLEMENTATION The described system was implemented in MATLAB (The MathWorks, Inc., USA) and compiled to run within the MATLAB environment. The routines together with four sample datasets are available at http://celmia.bigr. nl/. The software is planned for public release, free of charge for non-commercial use, after publication of this article.
A Semantics for Model-Based Spatial Reasoning

Model-based reasoning involves proving the truth of a proposition by computation in the semantic domain. In contrast, rule-based reasoning is proving truth by means of formal manipulation of formulas. A growing body of research in cognitive science suggests that human spatial reasoning is model-based, rather than rule-based. The paper begins with a cognitive perspective of model-based reasoning. A semantic domain for spatial reasoning, based on a theory of symbolic arrays, is de ned. A modal logic of spatial assertions for reasoning in indeterminate worlds is then presented, along with possible extensions that address structural hierarchy, temporal modalities, multiple views and analogy.
Reconceptualising Early Literacy Achievement: Moving beyond Critique-Paralysis

This paper takes early school-based literacy achievement as a particular example of the need to reconceptualise early childhood practices. By drawing on literacy results for identifiable groups of students, the paper argues the importance of moving beyond developmental continua and individual performance indicators in explaining and reviewing school-based literacy achievement. The particular example illustrates how early childhood educators can avoid ‘critique-paralysis’ by examining research data that yield substantial insights related to sociocultural and gender dimensions of literacy learning.
View-invariant human-body detection with extension to human action recognition using component-wise HMM of body parts

This paper presents a technique for view invariant human detection and extending this idea to recognize basic human actions like walking, jogging, hand waving and boxing etc. To achieve this goal we detect the human in its body parts and then learn the changes of those body parts for action recognition. Human-body part detection in different views is an extremely challenging problem due to drastic change of 3D-pose of human body, self occlusions etc while performing actions. In order to cope with these problems we have designed three example-based detectors that are trained to find separately three components of the human body, namely the head, legs and arms. We incorporate 10 sub-classifiers for the head, arms and the leg detection. Each sub-classifier detects body parts under a specific range of viewpoints. Then, view-invariance is fulfilled by combining the results of these sub classifiers. Subsequently, we extend this approach to recognize actions based on component-wise hidden Markov models (HMM). This is achieved by designing a HMM for each action, which is trained based on the detected body parts. Consequently, we are able to distinguish between similar actions by only considering the body parts which has major contributions to those actions e.g. legs for walking, running etc; hands for boxing, waving etc.
O uso do teletrabalho nas empresas de call center e contact center multiclientes atuantes no Brasil: estudo para identificar as forças propulsoras, restritivas e contribuições reconhecidas

This research thesis aimed to: 1) identify how and why call center and contact center companies use the method of telework performed by teleworkers in their homes; 2) identify the driving forces of telework in the surveyed companies; 3) identify the restrictive forces of residential telework of these companies; 4)verify contributions (earnings and profits) for the actors as a result of the use of telework (enterprises and teleworkers) involved in this process, and, 5) identify the process and reasons for the continuity or discontinuity of residential telework by these companies in the coming years. Six companies were initially considered. However, only four of them were surveyed. It was used the qualitative / quantitative method that combines the case study method and survey. The research findings revealed the residential telework has been used very sparingly. The companies whose cases were studied represent 92% of the population of call center and contact center providing service of this nature, by means of teleworkers in the residential segment in Brazil. The activities performed are more typical of call center and contact center, i.e., collections, telesales, customer satisfaction surveys, among others. The reasons for the use of this modality were: 1) cost reduction, 2) increasing productivity , 3) improving the quality of client service; 4) providing better quality of life for residential teleworkers with disabilities by giving them employment opportunities with social and digital inclusion. The driving and restrictive forces were identified as being of economic, social, legal and behavioral nature. The contributions (earnings and benefits) achieved by businesses and teleworkers were identified as economic,quality of life, social, environmental and institutional. It was found that three companies among the four surveyed intended to continue telework in the coming years. One company withdrew to continue with this mode at the end of this research and two that were found to integrate the objective analysis of this study withdrew before data collection.
Towards a High-Performance , Low-Power Linear Algebra Processor

Achieving high-performance while reducing power consumption is the key question as technology scaling is reaching its limits. It is well-accepted that application-specific custom hardware can achieve orders of magnitude improvements in efficiency. The question is whether such efficiency can be maintained while providing enough flexibility to implement a broad class of operations. In this paper, we aim to answer this question for the domain of matrix computations. We propose a design of a novel linear algebra processor and demonstrate that it can achieve orders of magnitude improvements in efficiency for matrix-matrix multiplication, an operation that is indicative for a broad class of matrix computations. A feasibility study shows that 46 doubleand 113 single-precision GFLOPS/W can be achieved in 13.6 and 11 GFLOPS/mm2, respectively with current components and standard 45nm technology.
Motivic decomposition of a generalized Severi-Brauer variety

Let A and B be two central simple algebras of a prime degree n over a field F generating the same subgroup in the Brauer group Br(F). We show that the Chow motive of a Severi-Brauer variety SB(A) is a direct summand of the motive of a generalized Severi-Brauer variety SBd(B) if and only if [A] = ±d[B] in Br(F). The proof uses methods of Schubert calculus and combinatorial properties of Young tableaux, e.g., the Robinson-Schensted correspondence.
The cellular, molecular and physiological mechanisms underlying the processing of proactive interference in the rat brain

Contrary to popular opinion forgetting can be useful: it will allow the filtering of non-essential information. The work of this thesis is to determine the biological basis of such adaptive forgetting, especially in the context of working memory (WM). We have adopted a comparative approach through the training of rats in a three behavioral tasks in a radial maze designed to test three distinct cognitive processes: the long-term memory, WM and treatment of proactive interference (PI). We have shown that information supposed to be stored in WM could last longer than necessary and interfere later with the storage of new information. Forgetting the first tests is therefore necessary to avoid PI. To understand the biological basis for this forgetting, we used three methodological approaches. We performed an immunohistochemical study aiming to understand what the brain region underlies the PI processing. This study showed that this processing requires inactivation of the dentate gyrus of the hippocampus. We then performed Western blot analysis in order to identify the molecular processes underlying this inhibition. This study shows that, in the hippocampus, different synaptic plasticity processes may occur during treatment of PI. The third approach is to understand when this processing occurs. This study shows a slow sleep role in the treatment of PI
Harmonic analysis on Heisenberg–Clifford Lie supergroups

We introduce a natural Fourier transform on the Heisenberg–Clifford Lie supergroup, covariant for the left regular representation. We prove a Fourier inversion formula, a Schwartz space isomorphism and Paley–Wiener–Schwartz theorem. The Fourier transform is an algebra homomorphism for a natural convolution product. This leads to the definition of convolution Banach algebra of Sobolev Wn, 1 type.
Channel selection based on amplitude and phase characteristics for P300-based brain-computer interface

Brain-Computer Interface (BCI) paradigms communicate with external world through specific electrode positions. As the oscillatory brain activity varies with different individuals, the prior experience is not enough to select the optimal channels for pattern recognition. Most channel selections are based on amplitude features. In this paper, an approach for channel selection that combines amplitude and phase features is proposed. Applied to the data set IIb of BCI Competition 2003, the method for channel selection achieved an satisfying accuracy that only one letter was predicted as wrong among thirty-one letters.
Supervisory Practices That Promote Academic Achievement in a New York City School.

This article and the two following describe school situations which, if not models for urban education, at least have achieved a degree of success in practicing some of the principles set forth in the preceding background articles. the establishment of attitudes and behaviors which will capitalize on the present resources of the school in fresh and challenging ways. Stress is not on superimposition of change from the outside but on modification of atti tudes and processes from within. Im proved results can be achieved through supervisory leadership that insists on the attainment of definite goals in teaching children.
Annual cyclicity in export efficiency in the inner Southern California Bight

The balance of marine autotrophy and heterotrophy regulates the ocean's ability to serve as a CO2 sink, as organic material produced by autotrophs sinks into the ocean interior to drive the biological pump. Marine ecosystems over the continental margins, especially coastal upwelling regions, account for a disproportionate amount of carbon export; thus, even small fluctuations in export in these regions can have a large impact on the global carbon cycle. In this study, we estimated the rate of gross oxygen production (GOP), stoichiometrically related to gross primary production, by combining measurements of the triple isotope composition of dissolved oxygen with estimates of vertical advection, eddy diffusion, and air‐sea gas exchange in a one‐dimensional two‐box nonsteady state model of the euphotic zone. Net oxygen production (NOP) estimates based on O2/Ar were then combined with GOP to estimate the NOP/GOP ratio, or potential export efficiency, out of the euphotic zone at the San Pedro Ocean Time‐series during an 18 month period between January 2013 and June 2014. GOP estimates ranged from 161 ± 44 to 477 ± 155 mmol m−2 d−1 during this period, peaking in May each year, and NOP/GOP ratios ranged from 0.05 ± 0.10 to 0.65 ± 0.28. The highest export efficiency occurred in late February/early March, following the onset of spring upwelling, declining as the upwelling season continued. This study demonstrates that export efficiency changes through time in this temperate coastal upwelling region on a repeated annual cycle, and the magnitude of export efficiency suggests efficient photosynthetic energy conversion by phytoplankton in spring.
Internet-Facilitated, Voluntary Counseling and Testing (VCT) Clinic-Based HIV Testing among Men Who Have Sex with Men in China

Objective To explore the feasibility of using Internet outreach to encourage men who have sex with men (MSM) to get tested for HIV at voluntary counseling and testing (VCT) clinics in Beijing and Urumqi, China. Methods From June to August 2007, two volunteers contacted MSM using instant messaging, online chat rooms, mobile phone, and e-mail (active recruitment). Banners with study information were put at the front pages of three major Chinese gay websites (passive recruitment). Those contacted were offered a modest financial incentive to seek HIV testing at existing VCT clinics. Those who subsequently sought HIV testing services at VCT clinics and provided informed consent completed a questionnaire and a blood draw to test for HIV and syphilis. Results A total of 3,332 MSM were contacted and 429 attended VCT clinics. One out of every 4 men that were recruited through instant messaging actually went for HIV testing, while the recruitment yields for online gay chat rooms, mobile phone contact, and email were 1∶6, 1∶10, and 1∶140, respectively. The majority of participants (80%, 317/399) reported being motivated to seek HIV testing out of concern for their health, and only 3% (11/399) reported being motivated by the financial incentive. Active recruitment tend to recruit MSM who are younger (X2 = 11.400, P = 0.001), never tested for HIV (X2 = 4.281, P = 0.039), tested less often (X2 = 5.638, P = 0.018). Conclusion Internet outreach is a promising way to encourage MSM to seek HIV testing at existing VCT clinics. Active recruitment can target MSM who are younger, never tested for HIV and tested less often.
Re-Establishing the Relationship with the Public

Public journalism is viewed by many as a solution to the decreasing media presence and public involvement in regional news media. Core values in this approach are public deliberation, participation, and connectedness. This study investigates the added value of a citizen-centred approach to journalism routines and news content in a collaborative regional media project in the Netherlands. Data were gathered using observations, interviews, and content analyses. Results show that even in a newly created news environment, existing journalistic routines largely prevent incorporation of a bottom-up approach in daily news production. Furthermore, active citizenship does not seem to be common: citizens did not participate readily in news production. While news content shows a greater focus on local communities and citizen sources, citizen sources were overwhelmingly used in vox pops rather than more active roles in which their expertise, experience, or specific knowledge was relevant.
