Evaluating performance of post‐tensioned steel connections with strands and reduced flange plates

The seismic performance of post‐tensioned steel connections for moment‐resisting frames was examined experimentally and analytically. Cyclic tests were conducted on three full‐scale subassemblies, which had two steel beams post‐tensioned to a concrete‐filled tube (CFT) column with high‐strength strands to provide recentring response. Reduced flange plates (RFPs) welded to the column and bolted to the beam flange were used to increase the dissipation of energy. Test results indicated that (1) the proposed buckling‐restrained RFP could dissipate energy in axial tension and compression, (2) the subassemblies could reach an interstorey drift of 4% without strength degradation, and (3) buckling of the beam occurred towards an interstorey drift of 5%, causing a loss of the strand force, the recentring response, and the moment capacity. A general‐purpose non‐linear finite element analysis program (ABAQUS) was used to perform a correlation study. The behaviour of the steel beam under both post‐tensioning and flexural loadings was compared to the test results and predictions. Copyright © 2006 John Wiley & Sons, Ltd.
HLA Expression in Relation to HLA Type in Classic Hodgkin Lymphoma Patients

Simple Summary Classic Hodgkin lymphoma (cHL) is a B-cell malignancy with involvement of Epstein–Barr virus (EBV) in about 30% of the European population. The risk to develop cHL is strongly linked to genetic variants in the human leukocyte antigen (HLA) genomic region and to certain HLA alleles. This may be caused by the function of HLA alleles, or by genetic linkage to non-HLA genes. HLA can present EBV-derived and tumour-cell specific antigens and this may lead to anti-tumour immune responses. However, the tumour cells downregulate HLA expression in a proportion of the cases, which may result in immune escape. In this study, we tested whether the loss of HLA expression is related to the presence of certain protective HLA alleles. We found that loss and retention of HLA expression is indeed associated with presence of known susceptibility HLA alleles. These findings suggest that HLA itself is involved in development of cHL. Abstract Several human leukocyte antigen (HLA) alleles are strongly associated with susceptibility to classic Hodgkin lymphoma (cHL), also in subgroups stratified for presence of the Epstein–Barr virus (EBV). We tested the hypothesis that the pressure on cHL tumour cells to lose HLA expression is associated with HLA susceptibility alleles. A meta-analysis was carried out to identify consistent protective and risk HLA alleles in a combined cohort of 839 cHL patients from the Netherlands and the United Kingdom. Tumour cell HLA expression was studied in 338 cHL cases from these two cohorts and correlated to the presence of specific susceptibility HLA alleles. Carriers of the HLA-DRB1*07 protective allele frequently lost HLA class II expression in cHL overall. Patients carrying the HLA-DRB1*15/16 (DR2) risk allele retained HLA class II expression in EBV− cHL and patients with the HLA-B*37 risk allele retained HLA class I expression more frequently than non-carriers in EBV+ cHL. The other susceptibility alleles showed no significant differences in expression. Thus, HLA expression by tumour cells is associated with a subset of the protective and risk alleles. This strongly suggests that HLA associations in cHL are related to peptide binding capacities of specific HLA alleles.
The design and application of rotary encoders

Purpose – The purpose of this paper is to highlight the increasing use of rotary or angle encoders and examine two distinct types of non‐contact encoders that employ novel technologies to meet the demands of very different applications.Design/methodology/approach – Firstly, examines the design characteristics of optical angle encoders which are used for precision applications such as rotary format computer‐to‐plate pre‐press machines, machine tool A, B and C axes, and surface mount machines. Then considers magnetic encoder design, including the latest OnAxis™ technology for lower cost applications which require less precision, but are often more physically demanding.Findings – Different rotary motion applications demand different combinations of performance and features to optimise their function – some require accuracy, others repeatability, high‐resolution or low‐cyclic error for velocity loop control, plus cost can also be a key consideration.Practical implications – There is an increasing need to cont.
Broad-Band Stripline Circulators Based on YIG and Li-Ferrite Single Crystals

The useful operating range of circulators has been extended by avoiding the "low-field loss" problems usually associated with operating at frequencies smaller than the magnetization frequency f/sub M/, through the use of a device configuration that assures a nearly uniform internal magnetic field. Performance data on experimental stripline circulators using single-crystal YIG or Li-ferrite disks and external YIG (or Li-ferrite) domes (for achieving a nearly uniform internal magnetic field) are summarized and compared with theoretical expectations. Reasonably good circulator performance is observed in the frequency range from 2.8 to 10.20 GHz for the circulator based on YIG and in the frequency range from 5.8 GHz to 18 GHz for the circulator based on Li-ferrite. The external ferrite domes improve the performance significantly when the frequency is near the lower edge of the operating band.
A compact coplanar waveguide‐fed monopole antenna with dual band‐notched functions for ultra‐wideband applications

A novel compact coplanar waveguide‐fed planar monopole ultra‐wideband (UWB) antenna with 3.5/5.4 GHz dual band‐notched functions is proposed in this article. To minimize the electromagnetic interferences between WiMAX/WLAN and UWB, a pair of inverted U‐shaped slots is etched in the center of the radiation element. The proposed UWB antenna achieves a wide band of 3–10.6 GHz for the VSWR less than 2, except the notched bands of 3.16–3.85 GHz and 4.96–5.82 GHz. Furthermore, a nearly omni‐directional radiation pattern and a stable gain ranging from 2.8 to 5.8 dBi are obtained except the rejected frequency bands. © 2012 Wiley Periodicals, Inc.

A wideband circular polarization antenna for portable INMARSAT BGAN terminal applications

A low profile, wideband, and portable antenna has been designed and fabricated for Inmarsat broadband global area network (BGAN) land mobile terminal applications. The purpose of the antenna was to provide a low‐cost and easy‐fabricated solution with wide bandwidth and high performance. The proposed antenna is composed of the stacked corner‐truncated patches with sequential rotation oblique feed and a serial feeding network. Good antenna characteristics are achieved over the BGAN operating bands. The measurement results for return loss, gain, axial ratio, and radiation pattern confirm the integrity of the simulation results. © 2009 Wiley Periodicals, Inc.

Utility foundation of a Cobb-Douglas demand function with two attributes

ABSTRACT It is known how to derive, from a utility maximization programme, a Cobb-Douglas demand function depending on the sole product price. This article shows how to derive a Cobb-Douglas demand function, which depends on both the product price and quality. More broadly, it offers a normative foundation, with a quasi-linear utility function, to the use of a Cobb-Douglas demand function of two attributes. It also provides simple measures of consumer surplus and social welfare.

Epoxy/Silicone Blend Loaded with N-Doped CNT Composites: Study on the Optoelectronic Properties

Thin films of epoxy/silicone loaded with N-CNT were prepared by a method of sol-gel and deposited on ITO glass substrates at room temperature. The properties of the loaded monolayer samples (0.00, 0.07, 0.1, and 0.2 wt% N-CNTs) were analyzed by UV-visible spectroscopy. The transmittance for the unloaded thin films is 88%, and an average transmittance for the loaded thin film is about 42 to 67% in the visible range. The optical properties were studied from UV-visible spectroscopy to examine the transmission spectrum, optical gap, Tauc verified optical gap, and Urbach energy, based on the envelope method proposed by Swanepoel (1983). The results indicate that the adjusted optical gap of the film has a direct optical transition with an optical gap of 3.61 eV for unloaded thin films and 3.55 to 3.19 eV for loaded thin films depending on the loading rate. The optical gap is appropriately adapted to the direct transition model proposed by Tauc et al. (1966); its value was 3.6 eV for unloaded thin films and from 3.38 to 3.1 eV for loaded thin films; then, we determined the Urbach energy which is inversely variable with the optical gap, where Urbach’s energy is 0.19 eV for the unloaded thin films and varies from 0.43 to 1.33 eV for the loaded thin films with increasing rate of N-CNTs. Finally, nanocomposite epoxy/silicone N-CNT films can be developed as electrically conductive materials with specific optical characteristics, giving the possibility to be used in electrooptical applications.
47.4: Invited Paper: 3D Displays using Scanning Laser Projection

Scanning laser projection technology is enabling advances in a number of areas of 3D display development. We discuss various scanned laser display technologies developed in our laboratory: 1) Our 1 mm × 9 mm projector uses a vibrating singlemode optical fiber to produce scanned images, and enables compact 3D head‐mounted displays with the potential form factor of a pair of eyeglasses. 2) Arrays of scanning fiber projectors can enable massively‐multi‐view autostereoscopic displays with full head motion parallax and partial accommodation cues, and 3) Our 3D volumetric displays triaxially scan light beams to render a volume, placing different pixels at different optical viewing distances to enable accurate accommodation and vergence cues.
Marine radar interrogator-transponder

The use of ship's radar for collision avoidance presents a fundamental problem in threat detection and identification since all vessel radar returns ("paints") look alike. As a result, when a ship master caught in a fog is trying to use his radio-telephone to work out a maneuvering plan with another vessel, it is difficult for him to identify which blip on the planar position indicator PPI is the source of the voice on the radio. One solution now receiving worldwide attention is to fit all vessels with active transponders. The marine radar interrogator-transponder (MRIT) is an advanced form of transponder which includes an integral interrogator and works in coordination with the ship radar to provide not only target identity and "clutter-free" target paints, but also maneuvering information and such data as target's course, speed, draft, safe or dangerous cargo, etc. Mounted on a fixed navigation aid, the transponder portion alone can also function as a racon (radar beacon). This paper describes the operational parameter and reviews the system bench tests and sea trials.
Application of Fault Tree Analysis in the Reliability Analysis of Oil-Gas Long Pipeline

Fault tree analysis method is used to carry out the safety and reliability analysis on the oil-gas pipelines in this paper. Firstly, establish the fault tree which top event is pipeline failure. Next, carry on the qualitative analysis to the fault tree. By the qualitative analysis, the authors can discover the major factors which induce the pipeline to failure and then establish the main risk fault tree. Finally, carry on the quantitative evaluation to the fault tree with main risk factors. Expert estimation and fuzzy mathematics analysis methods are used in the quantitative evaluation. In this way, the weak points of the pipeline system are distinguished, and we can also point out the basic event which improves easily if the pipeline system breaks down.

Sweet vs. Salty Former Food Products in Post-Weaning Piglets: Effects on Growth, Apparent Total Tract Digestibility and Blood Metabolites

Simple Summary Nowadays, researchers need to find a solution to the growing demand for sustainable animal productions. Livestock animal’s nutrition is the component with major impacts on environment and economy. The biggest challenge is to find alternative feed ingredients to minimize and valorize the food leftovers. Food industry leftovers, also called former food products, could be a valid alternative to grains in young pigs’ nutrition. From a nutritional point of view, these ingredients are very similar to standard cereals, like corn. The results from this study suggest that a partial substitution of standard ingredients with two different sources of former food products in the diets of post-weaned pigs is possible, without any negative effects on growth performance and health of animals. Abstract Former food products (FFPs) have a great potential to replace conventional feed ingredients. This study aimed to investigate the possibility to partially replace standard ingredients with two different types of FFPs: bakery (FFPs-B) or confectionary (FFPs-C) FFPs and their effects on growth performances, feed digestibility and metabolic status in post-weaning piglets. Thirty-six post-weaning piglets were randomly assigned to three experimental diets (n = 12 per diet) for 42 days: a standard diet (CTR), a diet where 30% of standard ingredients were replaced by confectionary FFPs (FFPs-C) and a diet where 30% of standard ingredients were replaced by bakery FFPs (FFPs-B). Individual body weight and fecal dry matter were measured weekly. Feed intake (FI) was determined daily. Average daily gain (ADG), average daily feed intake (ADFI) and feed conversion ratio (FCR) were calculated. Fecal samples were collected daily for three days/week to determine apparent total tract digestibility of dry matter (ATTD). At day 0, 21 and 42, blood samples were collected from all the piglets. No significant differences (p > 0.05) between groups were found in growth performances and metabolic profile. However, ATTD in FFPs-B group was lower (p < 0.05) compared to the CTR group at the end of the experiment. This study confirmed the possibility to formulate homogeneous diets integrated with 30% of both categories of FFPs. Further investigations are needed to clarify the effects of bakery former food products on the digestibility of the diet.
Matrix gas flow through ‘impermeable’ rocks – shales and tight sandstone

Abstract. The effective pressure sensitivity of gas flow through two shales (Bowland and Haynesville shales) and a tight gas sandstone (Pennant sandstone) was measured over the typical range of reservoir pressure conditions. These are low permeability rocks such as can be exploited as caprocks above reservoirs that might be developed to store compressed air, methane, hydrogen or to bury waste carbon dioxide, all of which may become important components of the forthcoming major changes in methods of energy generation and storage. Knowledge of the petrophysical properties of such tight rocks will be of great importance in such developments. All three rocks display only a small range in log10 permeability at low pressures, but these decrease at dramatically different rates with increasing effective pressure, and the rate of decrease itself decreases with pressure, as the rocks stiffen. The pressure sensitivity of the bulk moduli of each of these rocks was also measured, and used to formulate a description of the permeability decrease in terms of the progressive closure of narrow, crack-like pores with increasing pressure. In the case of the shales in particular, only a very small proportion of the total porosity takes part in the flow of gases, particularly along the bedding layering.
Somatic Embryogenesis in Vitis for Genome Editing: Optimization of Protocols for Recalcitrant Genotypes

New Plant Breeding Techniques (NPBTs) protocols have been developed to produce new grape varieties with improved quantitative and qualitative characteristics. Reliable transformation protocols for grapes are based on the generation/induction of embryogenic callus cells that are then transformed. Varieties such as Italia have proven to be very recalcitrant to regeneration via somatic embryogenesis. In this work, the development of a protocol for improved production of embryogenic calluses is described. Two sterilization protocols were tested: (a) a lower active chlorine concentration for a longer time (LS); and (b) a higher chlorine concentration for a shorter time (HS), in combination with the absence or presence of citric acid in the growing substrate in the first growth media. The embryogenic calluses formation in Chardonnay, a cv. with a high embryogenic response, was significantly higher in presence of citric acid in the initial growing substrate regardless of the sterilization protocol. In Aglianico, a cv. with a lower embryogenic response, no significant differences were observed. Instead, in a recalcitrant cv. as Italia, we obtained a 13-fold increase in embryogenic calluses formation performing sterilization of flowers with the HS protocol compared to LS.
Research Trends in Network-Based Intrusion Detection Systems: A Review

Network threats and hazards are evolving at a high-speed rate in recent years. Many mechanisms (such as firewalls, anti-virus, anti-malware, and spam filters) are being used as security tools to protect networks. An intrusion detection system (IDS) is also an effective and powerful network security system to detect unauthorized and abnormal network traffic flow. This article presents a review of the research trends in network-based intrusion detection systems (NIDS), their approaches, and the most common datasets used to evaluate IDS Models. The analysis presented in this paper is based on the number of citations acquired by an article published, the total count of articles published related to intrusion detection in a year, and most cited research articles related to the intrusion detection system in journals and conferences separately. Based on the published articles in the intrusion detection field for the last 15 years, this article also discusses the state-of-the-arts of NIDS, commonly used NIDS, citation-based analysis of benchmark datasets, and NIDS techniques used for intrusion detection. A citation and publication-based comparative analysis to quantify the popularity of various approaches are also presented in this paper. The study in this article may be helpful to the novices and researchers interested in evaluating research trends in NIDS and their related applications.
Effects of Net Height Scale on Badminton Performance and Satisfaction among Children

The height of the net scaling accordance with the physical size is important to improve performance and produce optimal shot kinematic characteristics in children. This study aimed to identify the average rate of optimal net height scaling among children aged seven to nine years. This study uses an experimental design with a total of 48 children randomly selected as study participants. Participants were divided into 24 pairs (boys = 12 pairs, female = 12 pairs) which were equivalent in terms of skill level and gender. All participants played against their respective pairs using four net height situations namely JP (155 cm), JM100 (127 cm), JM92 (117 cm) and JM82 (104 cm) situations reciprocally. All matches are conducted using a singles competition system with 11 points which is two sets per match situation. Data collection was done through video recordings and questionnaires. Shot performance was analysed from the aspects of serve success, shot chances and rally length. Participants' satisfaction with the four paired match situations was obtained through a questionnaire. Study data were analysed using SPSS version 16.0 program. The results of one-way ANOVA test for repeated measurements showed that there was significant mean score differences (p <.05) for performance and satisfaction between the JP, JM100, JM92 and JM82 situations. The findings of the study showed that scaling the net height of 92% of the average height of children aged seven to nine years was the optimal net height. Therefore, this study suggests that the use of standard net heights among children should be reviewed.
A numerical model for the piezoelectric transduction of stress waves

One of the most intensely studied forms of in situ structural health monitoring involves the use of piezoceramic disc elements to induce and transduce elastic stress waves. This paper reports on a numerical modelling facility for axisymmetric acousto-ultrasonic problems where a transversely-isotropic piezoelectric disc element is attached to or embedded in a structural host. The model accounts for both elasto-electromagnetic coupling and viscoelastic material behaviour. Experimental examples are shown to demonstrate good correlation between observed and predicted behaviour. Comparisons show that the predictive accuracy of the model depends profoundly on the quality of the material property data furnished. Where biased inputs are suspected, a remedy is proposed comprising stochastic optimization guided by observations of the system response.
