Vibration analysis for fault detection of automobile engine using PCA technique (2016)

Today condition monitoring using vibration analysis is not only used for simple proposes like bearings and gears fault detection but also it is used in hybrid motors and cars in automobile industry for detecting or anticipating faults. The main aim of this paper is using vibration analysis in automobile industry to detect and categorize faults appeared due to poppet valve clearance and incomplete combustion sometimes called misfiring phenomenon in internal combustion engine. So we used four accelerometers on OHV engine body for registering vibration signals. Then using PCA technique acquiring data were investigated. At the end we succeeded to classify and detect faults with a high ratio of efficiency.
Failure to Thrive in Infancy and Early Childhood: A Multidisciplinary Approach (1983)

This multiauthored book emphasizes the interdisciplinary team approach to the diagnosis and care of patients with failure to thrive (FTT). The authors have expertise in pediatrics and its subspecialties, including psychiatry, behavioral science, social work, and therapeutic recreation. In a book of this nature, uneven style and a certain amount of repetition are unavoidable. However, this book lacks cohesiveness and structure because some sections and chapters are inappropriately named, and there is divergent use of the term FTT. Contributors from the pediatric subspecialties use it as the name for a symptom. Psychiatrically oriented contributors, on the other hand, follow the 1980 recommendation of the American Psychiatric Association, which designated, unfortunately, nonorganic FTT as a disorder of maternal-infant bonding. Since they have a tendency to drop the nonorganic qualification, FTT becomes synonymous with maternal deprivation, which was renamed<i>reactive attachment disorder</i>(RAD). Failure to thrive may be a convenient code for

In particular, a linguistically relatively lightweight approach is deployed, in which clustered news are heavily exploited at all stages of processing. The paper focuses on the system's architecture, real-time news clustering, geolocating clusters, event extraction grammar development, adapting the system to the processing of new languages, cluster-level information fusion, visual event tracking and accuracy evaluation.
Hydrolysis and retro‐aldol cleavage of ethyl <i>threo</i>‐2‐(1‐adamantyl)‐3‐hydroxybutyrate: competing reactions (2010)

Abstract The hydrolysis of ethyl threo ‐2‐(1‐adamantyl)‐3‐hydroxybutyrate ( 1 ) and the parent ester ethyl 3‐hydroxybutyrate ( 4 ) has been studied experimentally and computationally. In the hydrolysis of threo ‐ester 1 with 2 M NaOH, predominantly retro‐aldol product was observed, whereas the hydrolyzed product was present in a minor amount. When the reaction is carried out under the same conditions with the parent ester ethyl 3‐hydroxybutyrate ( 4 ), hydrolyzed product is exclusively observed. The competitive pathways, namely hydrolysis and the retro‐aldol reaction for 1 and 4 were investigated using DFT calculations in the both gas and solvent phase. The calculated results in the solvent phase at B3LYP/6–31 + G* level revealed that the formation of retro‐aldol products is kinetically preferred over the hydrolysis of threo ‐ester 1 in the presence of a base. However, the parent ester 4 showed that the retro‐aldol process is less favored than the hydrolysis process under similar conditions. The steric effect imposed by the bulky adamantyl group to enhance the activation barriers for the hydrolysis of the ethyl threo ‐2‐(1‐adamantyl)‐3‐hydroxybutyrate ( 1 ) was further supported by the calculations performed with tert ‐butyl group at the α ‐carbon atom of ethyl 3‐hydroxybutyrate ( 7 ).

Edible ectomycorrhizal mushrooms: challenges and achievements (2004)

There are about 2500 recorded species of edible mushrooms. The most expensive and sought after of these mushrooms belong to the mycorrhizal group and include Tuber melanosporum Vitt. (Périgord black truffle), Tuber magnatum Pico & Vitt. (Italian white truffle), Tricholoma matsutake (Ito & Imai) Sing. (matsutake), Boletus edulis Bull: Fr. sensu lato (porcini) Cantharellus cibarius Fr.: Fr. (chanterelle), and Amanita caesarea (Scop.: Fr.) Pers: Schw. (Caesar's mushroom). The total market for these is measured in billions of US dollars. Over the past 100 years, harvests of many mycorrhizal mushrooms have declined dramatically, which has prompted interest in the development of methods for their cultivation. So far only a few species of truffles have been produced in commercial quantities, although methods have been developed that may see the cultivation of species such as Cantharellus cibarius, Lyophyllum shimeji (Kawam.) Hongo, and Lactarius deliciosus (L.: Fr.) Gray. Despite this, many of the most expensive mycorrhizal mushrooms, including Tuber magnatum Pico & Vitt. and Tricholoma matsutake, have defied cultivation. Our paper will attempt to highlight possible reasons why mycorrhizal mushrooms have proven to be so difficult to grow and how we might better manage mycorrhizal mushroom forests to sustain natural production.Key words: edible, ectomycorrhiza, mushroom, truffle.
Thermodynamic and kinetic studies on saccharide binding to soya-bean agglutinin (1986)

The fluorescence of N-dansylgalactosamine [N-(5-dimethylaminonaphthalene-1-sulphonyl)galactosamine] was enhanced 11-fold with a 25 nm blue-shift in the emission maximum upon binding to soya-bean agglutinin (SBA). This change was used to determine the association constants and thermodynamic parameters for this interaction. The association constant of 1.51 X 10(6) M-1 at 20 degrees C indicated a very strong binding, which is mainly due to a relatively small entropy value, as revealed by the thermodynamic parameters: delta G = -34.7 kJ X mol-1, delta H = -37.9 kJ X mol-1 and delta S = -10.9 J X mol-1 X K-1. The specific binding of this sugar to SBA shows that the lectin can accommodate a large hydrophobic substituent on the C-2 of galactose. Binding of non-fluorescent ligands, studied by monitoring the fluorescence changes when they are added to a mixture of SBA and N-dansylgalactosamine, indicates that a hydrophobic substituent at the anomeric position increases the affinity of the interaction. The C-6 hydroxy group also stabilizes the binding considerably. Kinetics of binding of N-dansylgalactosamine to SBA studied by stopped-flow spectrofluorimetry are consistent with a single-step mechanism and yielded k+1 = 2.4 X 10(5) M-1 X s-1 and k-1 = 0.2 s-1 at 20 degrees C. The activation parameters indicate an enthalpicly controlled association process.

Modifying Glass Fiber Size by Plasma Treatment (2012)

Abstract The performance of fiber-reinforced polymer matrix composites is strongly determined by the interfacial adhesion between fiber and matrix. As polymer matrix and inorganic glass fibers are chemically different, glass fiber sizing has to be employed to enhance fiber matrix adhesion. A new approach to optimize fiber matrix adhesion is an atmospheric pressure plasma treatment of the glass fiber reinforcement resulting in modifying and activating the glass fiber size. It is well known that adhesion can be improved by plasma treatment. To identify how the plasma acts and how the size is modified by the plasma, a commercial silane size was treated with a dielectric barrier discharge in air and analyzed by X-ray photoelectron, IR, NMR and Rutherford backscattering spectroscopy. The appearance of new OH, ester, carboxyl groups was observed. The modification consisted mainly of polyether chain scissions as a consequence of the formation of hydroperoxides.
The microRNA -23b/-27b Cluster Suppresses the Metastatic Phenotype of Castration-Resistant Prostate Cancer Cells (2012)

MicroRNAs (miRs) are small, endogenous, non-coding RNAs that regulate the stability and/or translation of complementary mRNA targets. MiRs have emerged not only as critical modulators of normal physiologic processes, but their deregulation may significantly impact prostate and other cancers. The expression of miR-23b and miR-27b, which are encoded by the same miR cluster (miR-23b/-27b), are downregulated in metastatic, castration-resistant tumors compared to primary prostate cancer and benign tissue; however, their possible role in prostate cancer progression is unknown. We found that ectopic expression of miR-23b/-27b in two independent castration-resistant prostate cancer cell lines resulted in suppression of invasion and migration, as well as reduced survival in soft agar (a measure of anoikis). However, there was no effect of miR-23b/-27b on cell proliferation suggesting that these miRs function as metastasis (but not growth) suppressors in prostate cancer. Conversely, inhibition of miR-23b/-27b in the less aggressive androgen-dependent LNCaP prostate cancer cell line resulted in enhanced invasion and migration also without affecting proliferation. Mechanistically, we found that introduction of miR-23b/-27b in metastatic, castration-resistant prostate cancer cell lines resulted in a significant attenuation of Rac1 activity without affecting total Rac1 levels and caused increased levels of the tumor suppressor E-cadherin. Inhibition of these miRs had the opposite effect in androgen-dependent LNCaP cells. These results suggest that miR-23b/-27b are metastasis suppressors that might serve as novel biomarkers and therapeutic agents for castration-resistant disease.
A Performance Study of Circular Polarization Selective Structures (2015)

A circular polarization selective structure (CPSS) reflects one handedness of circular polarization and transmits the other. In this paper the performance of a number of classical CPSS designs has been evaluated at the center frequency of operation for all possible spherical incidence angles. The results are presented in a compact way using two dimensional contour plots to represent the return loss, insertion loss and polarization purity of the transmitted and reflected signals. The results indicate that all CPSS designs presented up to date have preferred incidence planes of operation. The existence of geometrical symmetries in the designs affect the performance stability of the structures with respect to oblique angles of incidence. Applications of CPSSs in satellite communication systems, for example as a circular polarization dual aperture antenna or a circular polarization diplexer, require the structures to operate at wide ranges of oblique angles of incidence, making this type of analysis crucial for future development and evaluation of circular polarization selective structures.
Development of Endocannabinoid-Based Chemical Probes for the Study of Cannabinoid Receptors (2011)

We report the synthesis of new chemical probes (1a,b, 2a-c, 3a-c) based on the structure of the main endocannabinoids for their use in biological systems directly or via click chemistry. As proof of concept, 2-arachidonyl glyceryl ether based biotinylated 3b enables direct visualization of CB(1) receptor in cells. These results represent the starting point for the development of advanced small molecule chemical probes able to generate valuable information about the cannabinoid receptors.
A PDSI with STBC scheme for PAPR reduction in OFDM system (2011)

In this study, we have proposed a partition dummy sequence insertion (PDSI) method to reduce the high peak-to-average power ratio (PAPR) problem for the Orthogonal Frequency Division Multiplexing (OFDM) signal in the 802.11a WLAN with space-time block coding (STBC) system. The results show that the proposed STBC-PDSI method can avoid the BER degradation for different nonlinearity and the saturation point from the system simulation.
Automated Optimal Architecture of Deep Convolutional Neural Networks for Image Recognition (2016)

Recent advancements in deep Convolutional Neural Networks (CNNs) have led to impressive progress in computer vision, especially in image classification. CNNs involve numerous hyperparameters that identify the network's structure such as depth of the network, kernel size, number of feature maps, stride, pooling size and pooling regions etc. These hyperparameters have a significant impact on the classification accuracy of a CNN. Selecting proper CNN architecture is different from one dataset to another. An empirical approach is often used in determining the near optimal value of these hyperparameters. Some recent works have tried optimization techniques for hyperparameter selection as well. In this paper, we develop a framework for hyperparameter optimization that is based on a new objective function that combines the information from the visualization of learned feature maps via deconvolutional networks, and the accuracy of the trained CNN model. Nelder-Mead Algorithm (NMA) is used in guiding the CNN architecture towards near optimal hyperparameters. Our proposed approach is evaluated on CIFAR-10 and Caltech-101 benchmarks. The experimental results indicate that the final architecture of a CNN obtained by our objective function outperforms other approaches in terms of accuracy. It is shown that our optimization framework contributes to increase in the depth of network, shrinks the size of stride and pooling sizes to obtain the best CNN architecture.
Quantification of Metamorphopsia Using Hyperacuity Techniques (1991)

We have developed a new technique for quantification of metamorphopsia using a simplified and modified Amsler grid. Furthermore, the technique used is a bisection task, a form of hyperacuity determination. This allows for very fine assessments of metamorphopsia even in the presence of cataracts.
Adaptive speed identification for vector control of induction motors without rotational transducers (1992)

A model-reference adaptive system (MRAS) for the estimation of induction motor speed from measured terminal voltages and currents is described. The estimated speed is used as feedback in a vector control system, thus achieving moderate bandwidth speed control without the use of shaft-mounted transducers. This technique is less complex and more stable than previous MRAS tacholess drives. It has been implemented on a 30 hp laboratory drive, where its effectiveness has been verified.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
On-line storage management with distributed decision making for content-centric networks (2011)

Content traffic proliferation in Internet makes more dire than ever the development of radical new network architectures, where information will be addressed by semantic attributes rather than the origin and destination identities. In this direction, content-centric networking appears as a flexible communication model that meets the requirements of the content distribution trends of the future Internet. In such networks, information will reside at various locations/nodes (the Content Delivery Network surrogate servers) and the requests of the users for some piece of information will be directed to the closest replica. Since the location of the users and the popularity of the content varies over time, the problem of finding the optimal replication pattern for the available content, given the storage constraints, comes into the foreground. In this paper, we propose two on-line storage management algorithms of gradient descent type, designed specifically for content-centric networks. The proposed algorithms are of polynomial complexity and thus adapt easily to any environmental changes. Each node re-assigns its information items with the aim to minimize the overall traffic cost of the content delivery as the popularity and locality of users' requests change. While both the proposed algorithms operate in a distributed way, differ in the amount of information required for the decision making. Thus, we identify the inherent information - performance tradeoff and compare them in terms of network traffic, convergence speed and amount of circulated information.

Perifusion of Isolated Rat Islets in Vitro: Participation of the Microtubular System in the Biphasic Release of Insulin (1972)

A simple perifusion system for in vitro studies on the rate of insulin secretion of isolated rat islets is described. A biphasic pattern of insulin secretion was produced by glucose whereas tolbutamide stimulated only the first phase of insulin secretion. The perifusion system was used to determine the effect of anti-mitotic agents on the biphasic pattern of insulin secretion. Yinblastine and colchicine destroy microtubules whereas deuterium oxide (D2O) produces stabilization and interference with the function of microtubules. Vinblastine (10-4 M) and D2O (100 per cent) inhibited completely the first and second phase of glucose-induced insulin secretion. The inhibitory effect of D2O was reversible and a biphasic pattern of secretion occurred following the replacement of D2O with water. Colchicine (10-3 M) produced significant inhibition of only the second phase of glucose-induced insulin secretion. The first phase of tolbutamide-induced insulin secretion was inhibited by vinblastine and D2O and the inhibitory effect of D2O was reversible. Colchicine did not inhibit the first phase of tolbutamide-induced insulin release. These findings indicate that the microtubular system is involved in both phases of insulin secretion. The first phase of secretion may be due to the release of beta granules already associated with the microtubular system and the second phase could be the result of stored and newlysynthesized granules becoming associated with the system.
