Concepts for and analysis of a high accuracy and high capacity (HAHC) aerospace robot

Case study work carried out within the aerospace sector has highlighted the requirement for highly accurate and high capacity robots in aerospace assembly; literature supports this observation. This paper presents the generic capabilities of such a system. These include the ability to rapidly locate itself within a large measurement volume using supplementary laser metrology systems, to carry out detailed inspection beyond the line of sight, and to accurately locate parts, drill holes and fettle interfaces. Concepts are presented for a standardized robot which would provide a flexible automation system able to carry out a full range of operations required in the assembly of large aerospace structures. Two possible solutions are detailed, one based on error mapping and one based on the physical isolation of encoders from structural loading using an exoskeleton approach.
Engineering design support through case-based reasoning

The potential application of case based reasoning (CBR) in design support is illustrated by means of three examples drawn from past and current research at the University of Paisley. The examples demonstrate the suitability of CBR in different aspects of design, different problem areas, and to meet different design goals. The examples are: a quality advisory system for the designer in the early stages of mechanical engineering design; the integration of case based reasoning with aspects of quality function deployment as a means of identifying suitable metrics in software engineering design; a domain and tool independent environment to support the traceability and documentation of the work of either a single designer or a design team in conceptual design.
Reference range of naïve T and T memory lymphocyte subsets in peripheral blood of healthy adult.

Naïve T and T memory cell subsets are closely related to immune response and can provide important information for the diagnosis and treatment of immunological and hematological disorders. Lymphocyte compartment undergo dramatic changes during adulthood; age-related reference values derived from healthy individuals are crucial. However, extensively detailed reference values of peripheral blood lymphocytes in whole spectrum of adulthood detected by multi-color flow cytometry on a single platform are rare. 309 healthy adult volunteers were recruited from Tianjin in China. The absolute counts and percentages of CD3+CD4+ T cells, CD3+CD8+ T cells, naïve T cells (Tn), T memory stem cells (Tscm), central memory T cells (Tcm), effector memory T cells (Tem), terminal effector T cells (Tte) were detected by flow cytometry with single platform technologies. Reference range of absolute counts and percentage of T lymphocyte subsets were formulated by different age and gender. The results showed that Tn and Tscm cells, which had stem cell properties, decreased with aging; while, Tcm and Tem increased with aging, which increased from 18 to 64 years old but presented no significant change over the 65 years old. Gender had influence on the fluctuation of lymphocyte subsets, absolute count of CD3+CD8+, CD8+ Tcm, CD8+ Tem in male were higher than those in female. The reference values of percentages and absolute numbers of naïve T and T memory cell subsets can help doctors to understand the immune state of patients and evaluate conditions of prognosis then adjust treatment for patients.
Life Stressors of Mechanical Contracting Supervisory Personnel

Retention of high quality management personnel is a priority for all companies in the construction industry, including mechanical contracting companies. Over the past several years there has been a decrease in managers in the construction industry, and firms that fail to retain these employees will be left with an understaffed workforce, which will hinder their ability to be competitive in the marketplace. In order to aid in retention efforts, mechanical contracting firms need to focus their attention on the factors that affect burnout, which leads to turnover of their management personnel. The majority of the research in the construction industry has focused on work related stress. There have been studies on life stressors in general and there are several tools available to measure these stressors, but no studies have been done on life stressors on mechanical contracting supervisors. Life stressors were identified using the LISRES-A survey for mechanical contracting supervisors. The results showed that these supervisors had well above-average levels of stress in regards to their children. The results suggest that contracting firms should tailor their employee assistance programs (EAPs) to help combat this stressor. By doing this, mechanical contracting firms can combat burnout and help retain their management personnel.
Systematic design of EMI-filters for power converters

EMI-filters are often designed by trial and error. To take guesswork out of filter design, a systematic approach is described in this paper. The design procedure is divided into three steps: (1) measurement of the impedance and amplitude spectrum of the noise source; (2) determination of the sink impedance; (3) calculation of the filter component values to fulfil a given limit curve with least costs for the overall filter. Using this design procedure, the filter topology, the filter order and the component values are determined to provide a lowest cost EMI-filter design.
Tieshan Port Development Plan: Evaluation of the Long Wave Induced Resonance Using a Numerical Mild-Slope Model

The general development plan of Tieshan port is designed to be long and narrow, for which the long wave induced resonance may be problematic. Within the present work, a numerical study on the effects of this kind of resonance is conducted. The simulations are performed with the use of the mild-slope model developed in Ref. [1], which was further validated in the present work to be able to predict reasonable results for the harbor resonance. To evaluate the wave resonance for the plan of Tieshan port, 71 offshore wave conditions with the period ranging from 50s to 400s have been calculated. The rationalities of the numerical solutions are analyzed through comparisons with the theoretical ones, and the general agreement is seen to be reasonable. Some preliminary results for the harbor resonant modes, the resonant periods and the corresponding amplification factors for the plan of Tieshan port have been presented.
Wavelet approach to power quality monitoring

Power quality issues have become more concerned with the extensive use of power electronic devices and nonlinear loads in the electric power system, the sensitive detection and accurate classification of power disturbances attracts more attention from both utilities and industrial customers. A wavelet transform based new approach to the detection of power disturbance and measurement of power quality is proposed in this paper. This approach adopts a series of complex wavelet functions as multi-channel band pass FIR filters to detect the occurrence of disturbance, and precisely estimate the instantaneous average magnitudes and frequencies in their respective frequency bands as time varies, which are essential to power quality assessment. The performance evaluation of the proposed approach has been conducted under a variety of disturbances including momentary interruption, sag, swell, flicker, harmonics, frequency deviation, transients etc., on the basis of simulations in MATLAB environment. The evaluation results demonstrate the effectiveness and advantages of the proposed approach.

Modeling and control of hybrid stepping motors

Starting from a simple flux model in the air gap, the magnetic equivalent model of the three-phase hybrid stepping motor is deduced. The voltage equation is obtained from the magnetic equivalent model. Since the procedure originates from the geometrical configuration of stator and rotor poles, the parameters of the voltage equation are closely related to the motor pole configuration. Therefore, the motor performance can be estimated from the voltage equation during the design stage of the motor. The control model of the motor can be easily obtained by applying a well-known d-q transformation. The validity of the proposed modeling is demonstrated by comparison between the designed and measured motor parameters and the control characteristics. <<ETX>>

Research into protection of rockfill dams from overtopping using rockfill downstream toes

The main cause of rockfill and embankment dam failures is overtopping due to insufficient outlet works. During the last 15 years, the Civil Engineering Department: Hydraulics and Energy of the Technical University of Madrid has been studying the overtopping failure process of rockfill dams. One of the aims of this research is to develop design criteria of cost-effective rockfill dam protections to avoid failure due to such overtopping. Among the different types of known protection, this analysis has focused on downstream rockfill toes. The objective of this study is to achieve stability of the downstream shell of rockfill dams to prevent mass slides. This article summarizes the results of the preliminary experimental and numerical tests developed during the year 2008. Preliminary conclusions show the feasibility of this protection to mitigate partially or totally the serious consequences of overtopping in rockfill dams.
Survey on Review Spam of E-Commerce Sites

Online shopping reviews provide valuable information for customers to compare the quality of products, and many other aspects of future purchases. People increasingly rely on information from E-commerce reviews. Product reviews is an important determinant of potential customers’ buying choices. However, spammers are joining this community to try to mislead consumers by writing fake or unfair reviews to confuse the consumers. Fake product review detection makes an attempt to detect fake reviews and remove them to restore the truthful ones for readers. To the best of our knowledge, there is still less published study on this problem. In this paper, we make a survey and an attempt to give a brief overview on review spam. The related work of fake product review detection is presented including web spam and spam email. Then some methods to detect review spam are introduced and summarized. The trend of review spam detection is concluded finally.
Fabrication of a microfluidic cell analyzer in a microchannel using impedance spectroscopy

The design, fabrication techniques and characterization of an on-chip flow-cytometer device as well as the packaging approach is described. The device consists of planar microelectrodes situated on one or both sides of a micro-channel connected to an electronic detection circuitry. Simulations of the cells effect on the channel impedance are presented and compared with real measurements. Efforts have particularly been focused on realizing an interconnecting setup to provide easy electrical and fluidic connections, to allow good monitoring and easy handling of the chip. The authors' cell analyzer is aimed at diagnostic applications for cell counting and separation in hematology (blood cells, leukocytes and reticulocytes). Another possible application is a micro-cell sorter that can be used to separate abnormal cell types that are present in samples at very low number such as cancer cells (cancer cytology).
Evaluation of Interactions between Buses and Bicycles at Stops

Buses and bicycles that share lanes interfere with each other, especially at bus stops. The primary objective of this study was to develop quantitative approaches to analyze interactions between buses and bicycles at bus stops. Field investigations were conducted at four types of bus stops in China. Observed data were used to test the significance of differences in bicycle speeds, and a model was proposed to predict the number of meeting events between buses and bicycles. Results indicate that bicycle speeds are influenced significantly when a bicyclist meets a bus at a bus stop where both vehicle types share the same lane. Setting strips to separate bus and bicycle movement trajectories can reduce or eliminate the impact on efficiency and safety. The number of meeting events between buses and bicycles can be used to characterize the level of service of this facility shared by buses and bicycles. The proposed model achieved relatively accurate prediction for the number of meeting events. The findings can contribute to a quantitative understanding of the effects on buses and bicycles at stops and to an evaluation of this facility shared by buses and bicycles.
The effect of worked material hardness on stone tool wear

The identification of ancient worked materials is one of the fundamental goals of lithic use wear analysis and one of the most important parts of understanding how stone tools were used in the past. Given the documented overlaps in wear patterns generated by different materials, it is imperative to understand how individual materials’ mechanical properties might influence wear formation. Because isolating physical parameters and measuring their change is necessary for such an endeavor, controlled (rather than replicative) experiments combined with objective measurements of surface topography are necessary to better grasp how surface modifications formed on stone tools. Therefore, we used a tribometer to wear natural flint surfaces against five materials (bone, antler, beech wood, spruce wood, and ivory) under the same force, and speed, over one, three, and five hours. The study aimed to test if there is a correlation between surface modifications and the hardness of the worked material. We measured each raw material’s hardness using a nano-indentation test, and we compared the surface texture of the flint bits using a 3D optical profilometer. The interfacial detritus powder was analyzed with a scanning electron microscope to look for abraded flint particles. We demonstrate that, contrary to expectation, softer materials, such as wood, create a smoother surface than hard ones, such as ivory.
Estimating DPL photomask fabrication load compared with single exposure

DPL (Double Patterning Lithography) has been identified as one of major candidates for 45nm and 32nm HP since ITRS2006update and several reports of the performance or challenges of DPL have been published. DPL requires at least two photomasks with tighter specification of image placement and the difference of mean to target according to ITRS2006update. On the other hand, approximately half of whole features of single layer are written on each photomask and the densest features are split into other photomask in consequence of pitch relaxation for DPL. Then the photomask writing data of two sets for DPL and single data for single exposure are evaluated for photomask fabrication load. The design will be automatically decomposed with EDA tool and OPC will be tuned as DPL or single exposure. Not only number of fractured features but also feasibility study of automatic decomposition will be presented and discussed. The consequences of relaxed pitch on process, inspection, repair, yield, MEEF and cycle time will be discussed with results as available.
OCT4 Suppresses Metastasis in Breast Cancer Cells Through Activation of STAT3 Signaling

Background: Metastatic breast cancer is the major cause of death in breast cancer patients. Activation of epithelial-mesenchymal transition (EMT) induces migration and invasion of breast cancer cells (BCCs). OCT4 (POU5F1) is a key transcription factor for reprograming and plays an important role in self-renewal. Recent studies recovered OCT4 may correlate with cancer progression. However, it is no sufficient proofs to verify how OCT4 plays in metastasis of breast cancer. In this present study, we show the role of OCT4 in the migration and invasion of BCCs in vitro and metastasis in vivo.Methods: PCR, Western Blot and Immunofluorescence staining were performed to determine to OCT4 expression in BCCs. Wound-healing assay and invasion assay were utilized to analyze the mobility of BCCs. Tumor metastasis was assessed with nude mice by subcutaneously injection. IHC assay was used to evaluate phosphorylated signal transducer and activator of transcription 3 (p-STAT3) expression in breast cancer tissues and normal breast tissues. To study whether OCT4 regulate EMT through STAT3 signal, we used shRNA to knockdown STAT3 gene expression in BCCs.Results: OCT4 changed cell morphology of BCCs, decreased cell adhesion, and inhibited migration, invasion and metastatic ability of BCCs. In the meantime, overexpression of OCT4 activated STAT3 signaling and changed EMT-related protein expressions in BCCs. However, knockdown of STAT3 in BCCs with overexpression of OCT4 could facilitate EMT.Conclusion: Our data demonstrate that OCT4 suppresses EMT in BCCs through activation of STAT3 signaling, which is a key mechanism in impeding BCCs migration and invasion. Collectively, these data suggest that elevating OCT4 expression may be an effective method for reducing the metastatic potential of BCCs, which could also contribute to developing new methods for diagnosis and new molecular target therapies in breast cancer metastasis.
Silicon‐based integrated millimeter‐wave CPW‐to‐dielectric image‐guide transition

In this article, a novel mm‐wave dielectric image‐guide (DIG) to CPW transition is proposed, fabricated, and successfully tested in the silicon technology. A DIG is implemented on high resistivity Silicon‐On‐Insulator (SOI) wafer. The image‐guide height and handle layer thickness are 500 μm and 130 μm, respectively. An Aluminum coplanar waveguide is patterned over the DIG. The measured transmission characteristics of the transition are in acceptable agreement with the simulation results. A transition (coupling) loss of about 1 dB has been achieved at 60 GHz. © 2014 Wiley Periodicals, Inc. Int J RF and Microwave CAE 24:490–497, 2014.
Fuzzy logic control for the contouring accuracy of XY positioning system

In this paper, we propose a fuzzy logic controller for XY positioning system. In motion control, the major sources of uncertainties are friction, inertia, stiffness and disturbances. These uncertainties should be taken into account by any high performance robust motion controller. A cross coupled controller utilizes all axis position error information simultaneously to produce accurate contours. However, the existing cross coupled controllers cannot overcome friction, backlash and parameter variation. Also, since it is difficult to obtain an accurate mathematical model of the XY system, we investigate a fuzzy logic cross coupled controller of an XY positioning system. The overall control system consists of three parts, the position controller, the speed controller, the fuzzy logic controller. New contour error vector computation method is also presented. The performance of the proposed controller is shown to be effectiveness through some simulations and experiments.
Properties of a novel noncascaded type, easy-to-design, ripple-free optical bandpass filter

The chief principle and properties of a novel noncascaded type optical bandpass filter with three unique general characteristics are presented. This device is based on a combination of a Michelson interferometer and a Gires-Tournois resonator (GTR). First, the filter has square-like frequency response with zero ripple, wide flat-top (0.74/spl times/bandwidth), unity contrast, sharp steepness, and infinite rejection ratio when GTR front surface mirror reflectance /spl rho/ is equal to one-third. Second, this filter possesses variable bandwidth and center wavelength tunability features with simple control mechanism and nanosecond temporal response potential. Third, the desired features of the filter can be synthesized easily by mere inspection since only three parameters are required, and their expressions are given in simple analytic forms. Numerical results showing these features are presented and other characteristics are briefly discussed.
GRT model for random telegraph signals in MOSFETS

This paper investigates the emission and capture kinetics of random telegraph signals (RTS) in MOSFETs. A modified two-step approach is proposed which includes the capture of a carrier by trap located at the Si-SiO2 interface, followed by a tunneling process of the trapped carrier between the interface trap and a trap located in the SiO2 layer. In this case the quantum transitions represent a primary process which involves three basic states. In some cases this can be approximated by a two states g-r process X2(t), which coincides with a secondary process Y(t) representing current modulation. It is shown that by this model a quadratic dependence of the capture rate on the drain current can be explained, provided that the quasi-Fermi level at the surface is below the interface trap level. From the presented model the ratio of interface trap cross-section and oxide trap cross-section determines the capture and emission time.
Towards an adapted lean system – a push-pull manufacturing strategy

Abstract The direct transplantation or imitation of lean production has led to difficulties of applying a number of lean principles and practices. Thus diffusion of one of the main lean principles, just in time production, which refers to producing only “what is really needed, when it is needed, and in the amount needed”, seems to be limited. To date, some of the these companies produce more than their customers really need. This method of production enables them not only to amortize the high changeover costs over a large number of products, but also to benefit from commercial opportunities. However these companies are exposed to financial losses related to storage costs and risks of non-sale. To provide decision elements for determining the best production strategy, we have developed a model for calculating the optimal quantity to be produced. Moreover, we suggest using a fuzzy aggregation system to optimise the consideration of the risk of non-sale. This new approach defines the limits to not be exceed by taking into consideration the drawbacks linked to the risks of non-sale.
