Using ASTFT Spectrum to Suppress Cross Terms in WVD and its Application in Fault Diagnosis

A new fault diagnosis method to suppress cross terms of Wigner-Ville distribution (WVD) using Adaptive Short-time Fourier Transform (ASTFT) spectrum is put forward. The relationships of correlation between auto terms and cross terms of WVD are obtained theoretically by analyzing the WVD. Firstly, the signal ASTFT spectrum which can determine the signal component positions in the time-frequency plane is obtained. Then, the ASTFT spectrum as a window function is selected to process the signal WVD. Thus the cross terms can be effectively restrained. The simulation results show that a better resolution and more effective suppression of cross terms can be obtained. At last, the proposed method is applied to the fault diagnosis of bearing. The simulation and the experiment results indicate that the proposed method is effective in feature extraction.
A Standard Fiber Optic Sensor Interface For Aerospace Applications: Time Domain Intensity Normalization (TDIN)

This paper describes an attractive approach for referencing fiber optic intensity sensors in mobile platforms where variations of source, fiber path, or receiver parameters can severely compromise measurement of the desired parameter. The approach, named Time Domain Intensity Normalization (TDIN), operates with a wide variety of intensity-based sensors and also provides a means for sensor multiplexing. It therefore can serve as the basis for a standard fiber optic sensor system interface. Various reference schemes for intensity sensors are compared, followed by discussion of optical and electronic design implementation of TDIN, including system multiplexing. Theoretical analyses of key performance issues and test results (using a position sensor mechanism) are discussed.

The aim of this study was to assess the optimal balance ration of concentrate and forage to improve dairy milk production. The research was conducted at regional operational unit Mulyorejo, Barukan village, Tengaran Sub District, Semarang Regency, and Banyu Aji Cooperative, Getasan Sub District, Semarang Regency. Data was analyzed at Feed Nutrition Science Laboratory, Faculty of Animal Husbandry and Agriculture, Diponegoro University Semarang. The research started from June 29 to July 31, 2014. The materials of this research were 12 Friesian Holstein dairy cows in second and third months of lactation with average estimated body weight 408.5±30.86 kg (Coefficient of Variance (CV) = 10.68%) with average milk production around 9.3±1.01 liters (CV = 14.33%). The study was experimental research with completely randomized design using three treatments, i.e. T0 (50% of concentrate and 50% of forage), T1 (45% of concentrate and 55% of forage) and T2 (40% of concentrate and 60% of forage). The results showed that T2 had a significant effect on milk fat content (P<0.05), solid non fat (SNF) content (P<0.05), milk protein content (P<0.01) and milk lactose content (P<0.05). This study concluded that the optimal balance ration of concentrate and forage to improve milk performance consisted of 40% of concentrate and 60% of forage.

Dual‐band bandpass filter using integrated open loop resonators with embedded ground slots

In this article, a dual‐band bandpass filter is proposed using two half wave length open loop resonators integrated in concentric topology. The outer set of resonators are realized to operate at lower pass band of 2.4 GHz which is coupled directly to input and output ports where as the inner set of resonators are designed at 3.5 GHz which is electromagnetically coupled to the outer resonator. To obtain wide passbands, enhanced coupling between the outer resonators is realized using ground slots just below the open loop sections of the resonators. The measured passband bandwidth at 2.45 and 3.5 GHz is 187 and 155 MHz respectively. Four transmission zeros, created due to source load coupling, are located close to the passband edges at 2.18, 2.68, 3.38, and 3.72 GHz to increase skirt selectivity. Over all filter dimension is 20 mm by 32 mm. An equivalent circuit model is developed that is in close agreement with full wave simulation and measured results. © 2012 Wiley Periodicals, Inc.

Experiments in high current switching using small contact gaps

A series of tests were performed on two types of commercial vacuum interrupters, herein called Type A and Type B to ascertain the effect of the contact gap on their high current interruption ability. The tests were carried out on a synthetic test plant at 12 kV, 31.5 kA for the Type A and 12 kV, 13.1 kA for the Type B, all values are rms. Three interrupters of each type were tested at contact gaps of between 8 mm and 1 mm. In addition, identical contacts were subjected to short circuit testing in a vacuum demountable chamber which allowed filming of the arc by means of a high speed camera. The results indicate that Type A showed a significant reduction in the probability of interruption of the rated short circuit current at contact gaps below 4 mm, whereas Type B showed no degradation at contact gaps down to 1 mm. The reasons for this are discussed.
Low-background Acyl-biotinyl Exchange Largely Eliminates the Co-isolation of Non-S-acylated Proteins and Enables Deep S-acylproteomic Analysis

Protein S-acylation (also called palmitoylation) is a common post-translational modification whose deregulation plays a key role in the pathogenesis of many diseases. Acyl-biotinyl exchange (ABE), a widely used method for the enrichment of S-acylated proteins, has the potential of capturing the entire S-acylproteome in any types of biological samples. Here, we showed that current ABE methods suffer from high background arising from the co-isolation of non-S-acylated proteins. The background can be substantially reduced by an additional blockage of residual free cysteine residues with 2,2’-dithiodipyridine prior to biotin-HPDP reaction. Coupling the low-background ABE (LB-ABE) method with label-free quantitative proteomics, 2,895 high-confidence candidate S-acylated proteins (including 1,591 known S-acylated proteins) were identified from human prostate cancer LNCaP cells, representing so-far the largest S-acylproteome dataset identified in a single study. Immunoblotting analysis confirmed the S-acylation of five known and five novel prostate cancer-related S-acylated proteins in LNCaP cells and suggested that their S-acylation levels were about 0.6-1.8%. In summary, the LB-ABE method largely eliminates the co-isolation of non-S-acylated proteins and enables deep S-acylproteomic analysis. It is expected to facilitate much more comprehensive and accurate quantification of S-acylproteomes than previous ABE methods.
Alterations of actin cytoskeleton and arterial protein amounts in patients with obstructive jaundice.

Background: Vascular hypo-responsiveness to vasopressors in patients with obstructive jaundice (OJ) is a common anesthetic event, which leads to perioperative complications and increased mortality. The cause of this clinical issue remains unclear. Here, changes in the artery of OJ patients were assessed by proteomic analysis. Methods: Ten patients with OJ due to bile duct or pancreatic head neoplasms were enrolled, alongside ten chronic cholecystitis or liver hemangioma cases forming the controls group. Vascular reactivity was measured before anesthesia on the day of surgery. Artery samples near or surrounding the removed tumor tissues were collected and evaluated by 2-dimensional electrophoresis. Proteins with differential expression were detected by MALDI-TOF mass spectrometry, with immunoblot confirmation. Results: Vascular hypo-reactivity in OJ cases as well as suppressed aortic response to vasoactive products were evidenced. We also found that actin cytoskeleton and several actin-binding proteins were up- or down-regulated in the artery of OJ patients. Conclusion: The newly detected regulated proteins prompt future functional investigations to unveil the mechanisms of vascular hypo-reactivity in patients with obstructive jaundice.

Leaky defect modes of two-dimensional VCSEL arrays

Two-dimensional photonic lattices with a low-index defect have been studied. Simulations demonstrate that this type of structure has potential for realizing single-spatial mode operation from a relatively large emitting aperture, making it ideal for fiber coupling applications. A 2-D finite difference model is used to calculate the radiation loss of the modes in various low-index defect based two-dimensional photonic lattices. The simulation results are also compared to the results from a comprehensive the 3-D bi-directional beam propagation model. These calculations have been used to guide mask design and the experimental realization of the defect VCSEL devices.
Robust and universal constant-g/sub m/ circuit technique [operational amplifiers]

A robust and universal circuit technique to maintain a constant transconductance, g/sub m/, in rail-to-rail amplifiers based on input stages made up of parallel-connected complementary differential pairs, is presented. The technique is universal, since it is valid regardless of the g/sub m//I/sub D/ characteristic of input devices. Also, the accuracy does not depend on any condition for matching n- to p-channel input transistors, which makes the technique robust. Experimental results obtained from a 0.8 /spl mu/m CMOS test-chip prototype, are given.
A reliable multisensor fusion strategy for land vehicle positioning using low-cost sensors

Many intelligent transportation system applications such as vehicle guidance, assistance driving, and safety alert require accurate, reliable, and continuous vehicle positioning whether in open environments or in Global-Positioning-System-denied environments. The way in which such positioning performance can be achieved using low-cost sensors is the main challenge for land vehicles. This paper proposes a reliable and cost-effective multisensor fusion strategy for real-time vehicle positioning. First, several key-data-preprocessing algorithms are developed to provide more accurate and richer information for subsequent global fusion. They include a sliding-mode observer for eliminating the noise from the wheel velocity, a recursive least-squares algorithm for vehicle attitude estimation and angle compensation, and a vehicle state estimator for estimating the unmeasured lateral vehicle state. Further, an interacting-multiple-model-based fuzzy-decentralized-information-filtering algorithm is developed to realize global fusion. In the implementation of the interacting-multiple-model-based fuzzy-decentralized-information-filtering algorithm, the decentralized-information-filtering algorithm is presented, which can conveniently isolate a Global Positioning System fault and fuse multiple observation sources with different sample rates, and the fuzzy inference module is designed and introduced to adjust model probabilities adaptively to make them more suitable for actual driving situations. Finally, the proposed strategy is evaluated through both simulations and experiments. The results validate the feasibility and the effectiveness of the proposed strategy.
Development and application of nickel alloys in aerospace engineering

Since the development of the Nimonic1 alloys for Sir Frank Whittle’s first jet engine, Henry Wiggin Ltd, now part of Special Metals Corporation, has been involved with the design and improvement of nickel alloys for aerospace engineering. Whilst much of this work continues to be in relation to alloys for the high strength/high temperature applications of turbine blades, discs, seals, rings and casings of aero engines, nickel alloys are being utilised for other key aerospace engineering areas such as tooling for composite manufacture. The focus of this paper is on four recent developments in nickel alloys for aerospace engineering, namely: disc alloys; low expansion superalloys; Inconel alloy 718SPF – a nickel base superalloy capable of being superplastically formed; Nilo (low expansion alloys) for composite tooling.

P‐27: Advanced Gate‐All‐Around Fin‐Like Poly‐Si TFTs with Multiple Nanowire Channels

The gate‐all‐around (GAA) fin‐like poly‐Si TFTs (FinTFTs) with multiple nanowire channels (MNCs) have been fabricated using a simple process to demonstrate high performance electrical characteristics. The fin‐like nanowire (NW) channel with high body thickness‐to‐width ratio (TFin/WFin), approximately equals to one, was realized only with a sidewall‐spacer formation. The unique suspending MNCs were also achieved to build the GAA structure. By the way, the GAA‐MNC FinTFTs showed outstanding three‐dimensional gate controllability and excellent electrical characteristics, which revealed a high ON/OFF current ratio (> 108), a low threshold voltage, a steep subthreshold swing, a near‐free drain‐induced barrier lowering and a good reliability. Therefore, such the high‐performance GAA‐MNC FinTFTs are very suitable for the applications in the system‐on‐panel (SOP) and three‐dimensional (3D) circuits.
Regulation issues and prediction of natural estrogen loads for wastewater treatment plants

A model was developed for the fate of the natural estrogens estrone (E1) and estradiol (E2) in municipal sewage collection systems. Six municipalities throughout the Northern Hemisphere provided data to aide in the calculation of the biotransformation/degradation kinetics of the natural estrogens estrone (E1) and estradiol (E2) in wastewater collection systems. The mean pseudo-first-order kinetic constant for the biotransformation of E2 into E1, kE2, was 0.030 hr-1 (ranging from -0.080 to 0.49 hr-1) and the mean value of the pseudo-first-order kinetic constant for the biodegradation of E1, kE1, was -0.18 hr-1(ranging from 0.44 to 0.38 hr-1) The mean total suspended solids concentration was 0.256 g/L (ranging from 0.103 to 0.450 g/L), and mean temperature was 16.8oC (ranging from 12 to 24.5 oC). Biodegradation k values were not found to be temperature sensitive within this range. Values for kE2 and kE1 displayed a trend of increasing with total suspended solids concentration.
Reconfigurable angular diversity antenna with quad corner reflector arrays for 2.4 GHz applications

The authors propose a reconfigurable angular diversity antenna, constructed with quad corner reflector arrays and switching control, that can provide effective polarisation. With switches in the control unit of the base station, a high radiation gain antenna to provide cross-pair polarisations for receiving operations, as well as an omni-directional radiation pattern for transmitting, has been reconfigured. Simulation and measurement results including frequency responses, radiation patterns and three-dimensional polar plots demonstrate the design of an antenna. Diversity measurements with correlation and root mean square (RMS) error vector magnitude (EVM) are presented in order to evaluate the proposed antennas. The angular diversity technique can be applied to wireless local area network (WLAN) and multiple-input and multiple-output (MIMO) systems.
Energy Efficiency of Cell Range Extension of Picocell

Energy efficiency is an important issue in the wireless communication system as the increasing number of wireless network users and the emerging data usage. Heterogeneous network (HetNet) is a possible way to reduce the energy consumption since the distance between user equipment (UE) and the base station is shortened in HetNet, which sharply reduce the pathloss between the transmitter and receiver. This paper investigates the energy efficiency of Pico-Macro system in terms of Joule per bit. A effects of using Cell Range Extension (CRE) of Picocell based on energy efficiency is investigated and verified through the simulation results.
