Automatic Identification of Shaft Orbits for Steam Turbine Generator Sets

The shaft orbits and dynamic characteristics of the shaft centre orbit contain abundant information for the fault diagnosis of rotating machinery and reflect different faults of rotating machine. Therefore the shaft orbits recognition plays an important role in the fault diagnosis of steam turbine generator set. An automatic identification method of shaft orbit for steam turbine generator sets is proposed in this paper. The median morphological filter combining the open-closing with clos-opening is used to eliminate the noise in the original X and Y vibration signals. Then the seven invariant moment feature are extracted from the shaft orbit reconstructed. Input the seven invariant moments to the trained BP neural network, the shaft orbit can be identified automatically. A case is verified this model. It is shown that this model is feasible and high precision for identify the shaft orbit in fault diagnosis.
The influence of eye height and avatars on egocentric distance estimates in immersive virtual environments

It is well known that eye height is an important visual cue in the perception of apparent sizes and affordances in virtual environments. However, the influence of visual eye height on egocentric distances in virtual environments has received less attention. To explore this influence, we conducted an experiment where we manipulated the virtual eye height of the user in a head-mounted display virtual environment. As a measurement we asked the participants to verbally judge egocentric distances and to give verbal estimates of the dimensions of the virtual room. In addition, we provided the participants a self-animated avatar to investigate if this virtual self-representation has an impact on the accuracy of verbal distance judgments, as recently evidenced for distance judgments accessed with an action-based measure. When controlled for ownership, the avatar had a significant influence on the verbal estimates of egocentric distances as found in previous research. Interestingly, we found that the manipulation of eye height has a significant influence on the verbal estimates of both egocentric distances and the dimensions of the room. We discuss the implications which these research results have on those interested in space perception in both immersive virtual environments and the real world.
Expeditious Synthesis of Noble Metal Nanoparticles Using Vitamin B12 under Microwave Irradiation

A greener synthesis protocol for noble nanometals is developed using vitamin B12 as a reducing and capping agent in conjunction with the use of microwaves. Successful assembly of nanoparticles or microparticles with varied shapes and sizes have been demonstrated. The synthesized Ag, Au, and Pd samples were thoroughly characterized with X-ray diffraction, scanning electron microscopy, transmission electron microscopy, high resolution transmission microscopy, and UV-visible spectrophotometry, confirming that metallic Ag, Au, and Pd were synthesized by the green chemistry method.
Optimizing query rewriting in ontology-based data access

In ontology-based data access (OBDA), an ontology is connected to autonomous, and generally pre-existing, data repositories through mappings, so as to provide a high-level, conceptual view over such data. User queries are posed over the ontology, and answers are computed by reasoning both on the ontology and the mappings. Query answering in OBDA systems is typically performed through a query rewriting approach which is divided into two steps: (i) the query is rewritten with respect to the ontology (ontology rewriting of the query); (ii) the query thus obtained is then reformulated over the database schema using the mapping assertions (mapping rewriting of the query). In this paper we present a new approach to the optimization of query rewriting in OBDA. The key ideas of our approach are the usage of inclusion between mapping views and the usage of perfect mappings, which allow us to drastically lower the combinatorial explosion due to mapping rewriting. These ideas are formalized in PerfectMap, an algorithm for OBDA query rewriting. We have experimented PerfectMap in a real-world OBDA scenario: our experimental results clearly show that, in such a scenario, the optimizations of PerfectMap are crucial to effectively perform query answering.
High frequency trading strategy using the Hilbert transform

The recent escalation in computing power and database capacity in major financial exchanges has brought a substantial increase in both data and information availability. The ever faster development of computers, sensors, and information channels in financial IT has rendered trading data easier to be collected than ever before. The present study examines how the Hilbert transform may be used for the detection of financial market cycles and market trends. In particular, this paper focuses on measuring cyclic patterns of high frequency data to enhance intraday trading. The proposed approach exhibits several advantages over more traditional trading methods, attributed to its consideration of complex variables.
High Powered Cluster Heads for Extending Sensor Network Lifetime

Extension of the lifetime for a sensor network is important for most if not all applications. We propose a method to extend network lifetime by introducing several special sensors with higher battery power than normal sensors. We use these special sensors as cluster heads until their battery capacity is reduced to that of a normal sensor node before adopting a low-energy adaptive clustering hierarchy (LEACH) type method. It is shown in this work that the network lifetime can be more than doubled when battery mAh of a special sensor is kept at 1500 mAh in comparison to normal sensors of 700 mAh. Comparing our approach with an equivalent LEACH system where the initial total battery capacities are equal in both methods, we achieve an increase of 104.23% in the network lifetime
Segmentation of IHC-stained Breast Tissues Images using SVM

— The present study is focused on the processing of breast cancer images, specifically immunohistochemistry (IHC) stained images. IHC is a technique that allows the detection of specific proteins in tissue sections. This technique is fundamental for the prognosis of certain cancers and for patient treatment The present study is focused on a specific IHC technique, the so called HercepTest , allows the detection of HER2 protein over-expression and is displayed by membrane staining. As a rule, pathologists perform qualitative analysis of tissues through visual inspection. , this could produce subjective results and is clearly not suitable for large scale processing. This paper describes the use of Support Vector Machine (SVM) to segment IHC images in order to obtain quantitative measurements of the stained membranes for determination of over-expressed HER2 protein.
Cryptography during Data Sharing and Accessing Over Cloud

Data sharing is an important functionality in cloud environment. With the advent of the World Wide Web and the emergence of e-commerce applications and social networks, organizations across the world generate a large amount of data daily. This data would be more useful to cooperating organizations if they were able to share their data. In this article, an efficient methodology is provided to securely, efficiently, and flexibly share data with others in cloud computing. In this technique, the secret key holder can release a constant-size aggregate key for flexible choices of cipher-text set in cloud storage, but the other encrypted files outside the set remain confidential. Secure cryptographic architecture and working methodology are proposed in this paper for optimal services over the cloud.
A 13 . 6-16 Gb / s Wireline Transceiver with Dicode Encoding and Sequence Detection Decoding for Equalizing 24 . 2 dB with 2 . 56 pJ / bit in 65 nm CMOS

This work presents an alternative strategy for communicating on bandwidth limited wireline channels without using conventional equalizers (FFE, DFE, CTLE): Dicode encoding and sequence detection decoding technique for lowbandwidth FR-4 channels. The key observation is that dicodeencoded data have no consecutive 1s or -1s. With this known information, the sequence detector at the receiver can correct errors due to inter-symbol interference. Implemented in 65nm CMOS, the proposed highly digital encoding and decoding approach can compensate for up to 24.2dB and 21.4dB loss with 2.56pJ/bit and 2.66pJ/bit efficiency while operating at 13.6Gb/s and 16Gb/s, respectively.
The essential oil from Lippia gracilis Schauer , Verbenaceae , in diabetic rats

The essential oil from Lippia gracilis Schauer (Verbenaceae) leaves was examined by GC and GC-MS. Fifteen constituents were identified. Carvacrol, p-cymene and γ-terpinene were found to be the major components. In the in vitro study, 5% solution of the Lippia gracilis Schauer oil presented antibacterial activity against Staphylococcus aureus isolated from diabetic patients with infected ulcers. The study evaluated the antibacterial activity of the 5% solution of the Lippia gracilis Schauer oil on the experimental model of diabetic adult male albino Wistar rats with leaft pelvic limb infected by Staphylococcus aureus strain. In this experiment, 28 diabetic Wistar rats were used, randomly distributed in four different groups of seven rats, (G1-white; G2-negative control; G3-positive control and G4-test). When comparing group G4 with G3, it was observed that the 5% solution presented a reduced CFU/mL level showing the antibacterial effect of the oil 24 hours after the administration of the inoculum (S .aureus without Lippia gracilis Schauer 108 ±313 versus S.aureus with Lippia gracilis Schauer 13.28±4.03). The results were expressed as mean±S.E. M. One-way analysis of the variance (ANOVA) was used. The differences between the minimum inhibitory concentration in vitro test were determined by the Tukey test (p<0.05). The Newman-Keuls test with level of significance (p<0.05) was used to measure the results in vivo. The findings have shown that 5% solution of the Lippia gracilis Schauer oil presented antibacterial activity in vitro and in vivo.
Small mammals of a forest reserve and adjacent stands of the Kelečská pahorkatina Upland ( Czech Republic ) and their eff ect on forest dynamics

The community of small terrestrial mammals (STM) was studied on seven experimental plots characterizing forest stands in various stages of succession development and with different level of management from plantings through production/commercial stands to a forest reserve. Increased attention was paid to dominant species and their effects on the dynamics of the forest reserve. In total, eight species of STM were detected with the highest dominance and abundance of Apodemus flavicollis and Myodes glareolus. The total relative abundance of STM was significantly highest in plantings (P < 0.05). A. flavicollis was significantly most abundant in production beech stands (P < 0.05), differences in the abundance among the other STM species being insignificant. The highest diversity was also determined in plantings (P < 0.05) as typical ecotone sites. Different natural conditions of open and high forest sites were also reflected in different weight of specimens of dominant species of STM from these biotopes. In A. flavicollis, the difference was highly significant (P < 0.01) and in M. glareolus significant (P < 0.05). Both species significantly affected the forest reserve dynamics through the consumption of forest seeds, particularly of beechnuts (100% consumption of the 2007 crop). However, according to the proportion of natural regeneration from previous years, the reserve proved resistance to the impact of rodents caused by the consumption of seeds in a long-term horizon.
Processing of a Multiple Membrane Spanning Epstein-Barr Virus Protein for Cd8+T Cell Recognition Reveals a Proteasome-Dependent, Transporter Associated with Antigen Processing–Independent Pathway

Epstein-Barr virus (EBV) latent membrane protein (LMP)2 is a multiple membrane spanning molecule which lacks ectodomains projecting into the lumen of the endoplasmic reticulum (ER). Human CD8+ cytotoxic T lymphocytes (CTL)s recognize a number of epitopes within LMP2. Assays with epitope-specific CTLs in two different cell backgrounds lacking the transporter associated with antigen processing (TAP) consistently show that some, but not all, LMP2 epitopes are presented in a TAP-independent manner. However, unlike published examples of TAP-independent processing from endogenously expressed antigens, presentation of TAP-independent LMP2 epitopes was abrogated by inhibition of proteasomal activity. We found a clear correlation between hydrophobicity of the LMP2 epitope sequence and TAP independence, and experiments with vaccinia minigene constructs expressing cytosolic epitope peptides confirmed that these more hydrophobic peptides were selectively able to access the HLA class I pathway in TAP-negative cells. Furthermore, the TAP-independent phenotype of particular epitope sequences did not require membrane location of the source antigen since (i) TAP-independent LMP2 epitopes inserted into an EBV nuclear antigen and (ii) hydrophobic epitope sequences native to EBV nuclear antigens were both presented in TAP-negative cells. We infer that there is a proteasome-dependent, TAP-independent pathway of antigen presentation which hydrophobic epitopes can selectively access.
Monetary Policy and Bank Lending in China — Evidence from Loan-Level Data

We investigate how monetary policy in a mixed financial system such as that of China, which is characterized by a juxtaposition of quantity- and price-based policy instruments and the co-existence of regulated and market-determined interest rates, affects bank lending. Using a newly constructed loan-level dataset, we find that loan rates but not loan size are affected by both the regulated and the market-determined interest rates and that loan size is instead affected by an implicit quota that is imposed on aggregate bank lending through window guidance. We interpret this finding to be evidence of credit rationing.
INDIVIDUAL INCOME TAX FUNCTIONS : AN EXPLORATORY EMPIRICAL ANALYSIS

Abstrad-We define and statistically estimate a nonlinear relationship between individual effective income tax ratet and economic income for United States tax return data for tax years 1979-89. The relationship , which we call the effective tax function, has three parametert and was theoretically derived from the theory of equal sacrifice by Young (1988, ,990) and more generally by Berliant and Gouveia (t9e3). Annual graphs of the statistically estimated effective tax functions are presented and used to characterize empirically the evolution of the United States federal tax system with respect to four characteristics of the tax tystem: average marginal tax rates, redistributional elastic-ities. revenue elasticities, and horizontal eguity. For each characteristic, we present a preliminary assessment of the impact of the 1986 tax reform. The major empirical finding rr that the effective income tax function exhibits a trend toward less pro-gressivity for the years studied. This general conclusion ls also valid for rndexes that measure the redistributive impact of the tax system (the elasticity of after-tax income with respect to before-tax income) and the rcvenue effects of the system (the elasticity of fiscal revenue with respect to before-tax income). ". a tax law is a mapping from a vector whose elements are the income characteristics of the individual (wage rncome, dividends, capital gains, and all the other items in the income tax form) to tax liabilities. lt is supposed to be a well defined function; no ec')-nomic analysis is needed. (. .) In fact, to use this information one wants to know the distribution of the burden by some classification of lower dimen-sionality than that used in the tax law. " in Arrow (1980. p. 265).
Real-Time Robot Joint Variable Extraction from a Laser Scanner

This paper describes a customized iterative closest point (ICP) algorithm for robot excavator bucket pose estimation and joint angle evaluation using a laser scanner. The proposed ICP variant handles noise, occlusion and partial- overlapping. The method has been tested on a Takeuchi mini-excavator and proved to be reliable with minimal workspace error. The angle estimations were found to be accurate. A comparison has been provided between the angle estimation results and the measurements from joint angle sensors.
Neuroligin 2 Controls the Maturation of GABAergic Synapses and Information Processing in the Retina

In the present study, we investigated the role of Neuroligin 2 (NL2) in synaptic transmission and network function using the mouse retina as a model circuit. We show that NL2 is preferentially located at GABAergic rather than glycinergic or glutamatergic postsynapses. The absence of NL2 from the retina resulted in a severe reduction of GABAA receptor clustering, and in subtle alterations of the retinal circuitry. Light processing was impaired accordingly, and retinal ganglion cells, the output neurons of the retina, showed increased basal activity and altered coding of visual information. Together, our data indicate that NL2 is essential for the functional integrity of GABAergic signaling and as a consequence, for information processing in the retina.
Joint Power Allocation for DF MIMO Relay Links with Hybrid Power Constraints

This paper deals with joint power allocation (PA) for decode-and-forward (DF) two-hop MIMO relay links with hybrid power constraints. In order to maximize the instantaneous information rate of each hop, we propose an optimal PA scheme via a primal--dual algorithm. Then, we jointly allocate the power between the source and the relay to improve the power efficiency further. The simulations will validate the proposed scheme and show that, compared with the traditional uniform PA, our scheme outperforms the counterpart.
Proteinuria Is Associated with Quality of Life and Depression in Adults with Primary Glomerulopathy and Preserved Renal Function

Background There is no information about HRQoL, depression and associated factors in adult with nephrotic syndrome-associated glomerulopathy. Methodology/Principal Findings Patients with primary glomerulopathy where compared with age and sex-matched hemodialysis patients and healthy subjects. Laboratory data, medical history, comorbid conditions were collected to evaluate factors associated with HRQoL (SF-36) and Depression (Hamilton Depression Rating Scale - HAMD). Glomerulopathy patients had low HRQoL in all eight SF-36 domains and two composite scores (physical and mental) in comparison with healthy subjects. HAMD score also was elevated and there was high depression prevalence. Overall, these data were comparable between glomerulopathy and hemodialysis patients. Using multiple regression analysis, factors associated with low HRQoL physical composite score were: last 24 h-urine protein excretion (−0.183, 95%CI −0.223 to −0.710 for each gram of proteinuria, p = 0.01) and cyclosporine use (−15.315, 95%CI −25.913 to −2.717, p = 0.03). Low HRQoL mental composite score was associated with last 24 h-urine protein excretion (−0.157, 95%CI −0.278 to −0.310 for each gram of proteinuria, p = 0.03) and HMAD score was independently associated with age (0.155, 95%CI 0.318 to 0.988 for each year, p = 0.04), female sex (4.788, 95%CI 1.005 to 8.620, 0 = 0.03), disease duration (0.074, 95%CI 0.021 to 0.128 for each month, p = 0.01) and last 24 h-urine protein excretion (0.050, 95%CI 0.018 to 0.085 for each gram of proteinuria, p = 0.02). Conclusions/Significance Nephrotic-syndrome associated glomerulopathy patients have low HRQoL and high prevalence of depression symptoms, comparable with those of hemodialysis patients. Last 24 h-protein excretion rate is independently associated with physical and mental HRQoL domains in addition to depression.
Evaluating the performance of public services: introducing the evaluator's comparison framework

As public services come under more scrutiny, practitioners are evaluating more of their investments in human capital. But, faced with numerous evaluation approaches, how do they compare them? This paper presents The Evaluator's Comparison Framework (ECF), a useful tool for comparing the planning, implementation (including monitoring and evaluation), and reporting elements of a project/initiative. It also demonstrates the framework in use with a comparison of the Logical Framework Approach (LFA) and the abdi Recommended ROI approach. From this demonstration, the differences between these approaches can be seen, allowing evaluators to select the one more appropriate to their needs.
A Submillimeter View of Circumstellar Dust Disks in ρ Ophiuchi

We present new multiwavelength submillimeter continuum measurements of the circumstellar dust around 48 young stars in the ρ Ophiuchi dark clouds. Supplemented with previous 1.3 mm observations of an additional 99 objects from the literature, the statistical distributions of disk masses and submillimeter colors are calculated and compared to those in the Taurus-Auriga region. These basic submillimeter properties of young stellar objects in both environments are shown to be essentially identical. As with their Taurus counterparts, the ρ Oph circumstellar dust properties are shown to evolve along an empirical evolution sequence based on the infrared spectral energy distribution. The combined ρ Oph and Taurus Class II samples (173 sources) are used to set benchmark values for basic outer disk characteristics: Md ∼ 0.005 M☉, Md/M* ∼ 1% , and α ∼ 2 (where Fν ∝ να between 350 μm and 1.3 mm). The precision of these numbers is addressed in the context of substantial solid particle growth in the earliest stages of the planet formation process. There is some circumstantial evidence that disk masses inferred from submillimeter emission may be underestimated by up to an order of magnitude.
