Delay spread measurements within a building at 2 GHz, 5 GHz and 17 GHz

Spectrum at microwave frequencies has been allocated within Europe and the United States for the evolving high bit rate wireless local area networking standards, namely ETSI HIPERLAN and FCC SUPERNET. This technology will also lead to other applications including the transmission of high quality digital video for wireless cameras. In order to design a radio-based high bit rate data transmission system the multipath time dispersion characteristics of the radio channel are an important consideration, and in particular, the RMS delay spread. Time domain measurements of RMS delay spread have previously been reported by other authors at frequencies up to 4 GHz. Frequency domain measurement systems have also been used to provide both time and frequency domain data including RMS delay spread, received power and coherence bandwidth. This paper presents new results for RMS delay spread measurements at the University of Wales Swansea. (6 pages)
Printed radiating element with two highly decoupled input ports

The authors present a very efficient technique based on the symmetry of the feeds to strongly reduce the port-to-port coupling of dual-polarisation printed antennas. This technique was applied to a dot-coupled microstrip stacked structure fed by stripline, a breadboard was made, and a decoupling of -35 dB or better was achieved over a large bandwidth.
Wet belt friction-induced dynamic instability and noise in Automotive Accessory Belt Drive Systems

This paper presents an investigation of V-ribbed belt (Micro-V TM ) wet friction and friction-induced slip noise in Accessory Belt Drive Systems (ABDS). A set of experiments was conducted by using an industry standard test rig and a standard material friction tester. A theoretical analysis and model are presented to elaborate the results. The tribological property of the interface is characterised to be unsteady mixed lubrication with water, which possesses the feature of negative slope of friction with velocity. The friction-induced dynamic instability and noises are also investigated. It is shown that the noise is directly associated with the negative slope of the friction-velocity curve.
A test of Rasmussen's risk management framework in the food safety domain: BSE in the UK

In 1986, bovine spongiform encephalopathy (BSE) was identified in the UK. Millions of BSE-infected cows were slaughtered and over 150 people contracted variant Creutzfeldt–Jakob disease, an inevitably fatal human form of BSE. Tragic incidents such as this provide valuable opportunities to understand and improve the safety of complex socio-technical systems. By studying accidents, knowledge can be gained that can improve system safety. The purpose of this article is to test the usefulness of Rasmussen's risk management framework for explaining how and why accidents occur in the food production domain. This was accomplished by using the framework to retrospectively investigate how and why BSE was transmitted through the human and animal food supply in the UK from 1986 to 1996. More specifically, an AcciMap and Conflict Map were constructed to represent contributing factors of the epidemic according to the structure of Rasmussen's framework. These factors were used to test the seven predictions made by the framework. All seven predictions were supported by the evidence, indicating that Rasmussen's risk management framework shows promise as a theoretically driven explanation of how and why accidents happen in complex socio-technical systems, particularly in the food production domain.
Impact on balance while walking in occupational footwear

Hazards and challenges present in the workplace pose a number of potential balance risks for injuries and illness. Purpose: The purpose of the study was to examine the differences in balance while walking for extended durations with different types of occupational footwear. Methods: Participants were tested for balance prior to walking session (Pre) and then again every 30 minutes until the 240th minute in three types of occupational footwear; work boots, tactical boots and low top shoes. Sway velocity and root-mean-square sway in the anterior-posterior and medial-lateral directions were evaluated using a 3 × 9 repeated measures analysis of variance to identify any existing differences within exposure time and footwear types. Results: Significant differences in postural sway were found over time in medial-lateral sway and between footwear in anterior-posterior and medial-lateral sway. Significant differences were found between the work boots, tactical boots and low top shoes, with the low top shoes exhibiting an increased postural sway. Conclusion: The changes in balance over time may be attributed to the workload placed on the individual resulting from the extended durations of walking/standing. Use of low top shoes resulted in a relatively greater balance decrement. The work boots and tactical boots despite having a greater mass, resulted in less of a balance decrement, which may be attributed to their elevated boot shaft height.
Determinants of early days of newborn feeding mal-practice among mothers of children less than one years of age in Mizan-Aman Town, South-west Ethiopia, 2020

Back ground: Neonatal death remained a global public health issue, especially in Ethiopia due to sub-optimal breast-feeding practices. While several interventions have been made to comply with the WHO guideline, sub-optimal feeding practices are commonly seen in Ethiopia. The goal of this study was therefore to identify gaps in optimal breast-feeding practice in South West Ethiopia.Objective: To assess the prevalence and determinant of early days of newborn feeding mal-practices among recently delivered women in Mizan-Aman Town, southwestern Ethiopia, 2020.Methods: A community-based cross-sectional study was undertaken on recently delivered women from March-April/2020. A total of 487 mothers-child (<12month) pair were selected by using multistage randomized sampling technique and the data was collected through face to face interview by using structured questionnaire. The result was analyzed via SPSS version 26. Multivariate logistic regression analysis was used to assess determinant of newborn feeding mal-practices and a p<0.05 was deem to be significant.Result: Prevalence of prelacteal feeding and colostrum avoidance was approximately 21.9% and 15.5% respectively. The most common prelacteal food was Rue / Tenadam/49 (10.1 %). The key reasons were: 49(10.1 %) Cultural activity followed by 45 (9.3 %) clean-up of the intestine / throat / mouth of babies. Determinants of pre-lacteal feeding were found to be: mothers recognizing risks of prelacteal feeding, multipara mothers, having ≥4 number of children and infant’s birth order 4-6. Likewise, exposure to infant formula advertisement, absence of home to home health education, multipara mothers and spontaneous vaginal birth were the determinants of colostrum avoidance.Conclusion: The study found that there was a sub-optimal breast-feeding practice, one in four newborns. As a result, activities to discourage pre-lacteal feeding and to improve early initiation of colostrum feeding practices shall be carried out.
Measurement of modal amplitudes of guided waves in rails

One important application of guided wave ultrasound is that of rail condition monitoring where long lengths of rail can be monitored from permanently attached transducer locations. During the development of transducers for such a system it is advantageous to be able to measure the amplitude of the individual modes of propagation on a short length of rail in the laboratory. This paper describes a method of extracting modal amplitudes from measured time domain signals performed at a limited set of points on the waveguide. The method uses the wave propagation characteristics of the waveguide, predicted by a semi-analytical finite element model, to extract the modal amplitudes from experimental measurements. The frequency response at a set of measurement locations is described by a superposition (with unknown amplitude coefficients) of the frequency response of the modes that propagate in the frequency range of interest. Experimental time domain responses are measured and transformed to frequency responses. The amplitude of each mode is estimated using the pseudo-inverse to provide a minimum norm least-squares estimate. The technique is demonstrated on a rail excited by a piezoelectric patch transducer. A laser vibrometer was used to measure displacements at five points around the rail circumference at three distances giving a total of 15 measurements. Eight propagating modes were extracted from these measurements. The extracted modes were then used to predict the response at points further along the waveguide and these predictions were verified by further measurements indicating that the modes of propagation were accurately estimated. The technique requires that the distance between the measurement points be known but does not require that the distance from the transducer be known. This feature and the fact that only a few measurements are required make the method suitable for measuring the propagation of individual modes over long distances in the field.
Emergency trip destination of evacuation as shelter anslysis for tsunami disaster: a case study in Phuket, Thailand

This paper aims to develop alternative forms of emergency trip destination (emergency shelter) and investigate the evacuee behaviors affecting the shelter choices for future tsunamis and other disasters. The shelter allocation forms are developed using the logistic regression model and neural network model in estimating the probability of evacuee choice of selecting evacuation destinations between public and private shelters. Not only the socio-economic factors that affect the selection decisions are presented, but this paper also intends to analyze the shelter attributes based on evacuee’s perceptions. These perceptions are expected to influence evacuee’s preferences among different alternatives. Data are collected in one of the most recent tsunami affected areas, Phuket, Thailand. Results of this study revealed that the emergency trip destination demand estimation does not provide only information for shelter requirement and shelter space but it can also be used to plan for emergency materials needed.

Airway Management with the Laryngeal Mask Airway (LMA) in Emergency Medical Services

Background: Airway management is an important aspect of care in emergency medical services (EMS) used to prevent obstruction of the respiratory track and inadequate oxygenation. The laryngeal mask airway (LMA) is an easy-to-use supraglottic airway device developed in 1988 that has a high success rate in both adults and children. However, there have yet been no studies regarding LMA use in EMS in Thailand. Objective: To determine the success rate of LMA in EMS and factors associated with successful LMA insertion. Materials and Methods: This was a cross-sectional study consisting of Srinagarind Hospital EMS patients over 18 years of age who underwent LMA airway management between March 2016 and March 2020. Data were collected from the Srinagarind Hospital EMS operation database and hospital information database system. Results: A total of 154 patients were enrolled with a mean age of 43.1+8.5 years, 89 (57.8%) of whom were male. Non trauma patients accounted for 72.7% of all cases. The average oxygen saturation before and after LMA use were 71.4+12.3% and 94.4+3.2%, respectively (p = 0.022). Students in their first and third year of residency training were able to successfully perform LMA airway management on the first attempt in 83.3% and 98.4% of cases, respectively (p = 0.025). Conclusion: Airway management using the LMA had a high success rate on the first attempt, required less time for insertion than other comparable devices, and resulted in a high level of oxygen saturation.

Mass Customization of Wedding Gowns: Design Involvement on the Internet

After an extensive search of bridal web sites was conducted and categorized in Fabruary and March 2001, a research web site was developed to study mass customization of wedding gowns. It offered choice of design features or components through interactive illustrations and was based on Duray’s conceptual framework of mass customization (Duray, 1997; Duray, Ward, Milligan & Berry, 2000). The site served as the experimental treatment for subjects. Following their visit to the site, the subjects completed a questionnaire that dealt with their experience and personal demographic information. A convenience sample of 100 young women between the ages of 18 and 32 was identified through e-mail recruitment. Results confirmed a high overall interest in involvement with the design of a wedding gown. Yet those subjects who were very interested in design involvement were significantly different than those who were less interested in spending more time or paying more money. Subjects who owned more personal technological devices and spent more time on computers and the Internet were significantly more willing to purchase the designed gown. Four categories of bridal web sites were identified based on site characteristics and strategies: marketing, browsing, advice, and customizing. Involvement in wedding dress design on the Internet is not yet available but appears to hold potential for the bridal industry. Research that studies the identification of potential customers by their high interest in design involvement, evaluation of product type and other interactive opportunities for design involvement, and use of Internet customization strategies with other channels of distribution is recommended.
Ultra-small MOSFETs: the importance of the full Coulomb interaction on device characteristics

We discuss a full three-dimensional model of an ultrasmall MOSFET, in which the transport is treated by a coupled EMC and molecular dynamics (MD) procedure to treat the Coulomb interaction in real space. Impurities within the device, including the source and drain regions, are treated as discrete charges and are randomly sited according to the nominal doping density of each region. We find that the inclusion of the proper Coulomb interaction significantly affects both the energy and momentum relaxation processes, but also has a dramatic effect on the characteristic curves of the device.
Effective Width of Locally Buckled Plates in Compression and Bending

The effective‐width concept has been recognized as an efficient way to compute the strength of locally buckled thin‐walled members. In a previous paper, an effective‐width formula for a locally buckled plate in combined compression and bending was presented. The formula was derived from the numerical results of an elastic postbuckling analysis of plates subjected to eccentric loading in its plane. The present paper is aimed to extend the previous study. An elastic‐plastic large‐displacement finite element (FEM) analysis has been performed to compute the ultimate strength of simply supported, initially imperfect steel plates in compression and bending. The plate is assumed to possess initial out‐of‐flatness as well as welding‐type residual stresses. Based on an extensive numerical study, a set of new effective‐width formulas have been derived as functions of both the magnitudes of initial out‐of‐flatness and compressive residual stress. Thus, the formulas could be used to predict the strength variations of.
Developing a sensor-based learning concentration detection system

Purpose – This study aims to use sensing technology to observe the learning status of learners in a teaching and learning environment. In a general instruction environment, teachers often encounter some teaching problems. These are frequently related to the fact that the teacher cannot clearly know the learning status of students, such as their degree of learning concentration and capacity to absorb knowledge. In order to deal with this situation, this study uses a learning concentration detection system (LCDS), combining sensor technology and an artificial intelligence method, to better understand the learning concentration of students in a learning environment. Design/methodology/approach – The proposed system uses sensing technology to collect information about the learning behavior of the students, analyzes their concentration levels, and applies an artificial intelligence method to combine this information for use by the teacher. This system includes a pressure detection sensor and facial detection s.
Hypertensive Heart Failure in Asia

Hypertension (HT) is an important risk factor for heart failure (HF). The prevalence of HT among the HF population is higher in Asia than in other regions around the world. In Asia, HT is the most common cause of HF after ischemic heart disease. Hypertensive HF (HHF) results from structural and functional adaptations of the heart, which lead to left ventricular (LV) hypertrophy (LVH). Hypertensive LVH can cause ventricular diastolic dysfunction and becomes a risk factor for myocardial infarction, which is a well-known cause of LV systolic dysfunction. Asymptomatic systolic and diastolic LV dysfunction easily progress to clinically overt HF with other precipitating factors. Although the precise pathophysiology of HHF is still unclear, we have known that HHF can be reversed by effective control of blood pressure (BP). Thus, HT control is essential not only for primary prevention but also for the secondary prevention of HF. Here, we reviewed the epidemiology, pathophysiology, outcome, and implication of BP management in HHF patients, especially in the Asian population.
Evaluation of tear production in juvenile opossum using three different methods

ABSTRACT: The establishment of parameters for tear production in different species is important for better understanding eye´s health and is one of the components of the ophthalmic semiological technique. Particularities derived from the anatomophysiology of non-domestic species induce the search for more reliable methodologies. The aim was to evaluate and compare tear production of white-eared opossum (Didelphis albiventris) and Brazilian common opossum (Didelphis aurita) by three different methods. Fifteen individuals of each species, juveniles, healthy, of both sexes, with 60 to 90 days of life, were physically restrained. Phenol red thread test (PRTT), endodontic absorbent paper point tear test (EAPPTT) and modified -Schirmer tear test (mSTT) were performed. PRTT was the most difficult to perform because of the wire malleability, while EAPPTT was more feasible for both species. The median ± semi-quartile range for PRTT were 19.79±2.61mm/15 “and 5.22±2.92mm/15”, for EAPPTT were 16.25±1.82mm/min and 10.9±3.04mm/min, and for STTm were 0±1.63mm/min and 0±1.63mm/min for white-eared opossum and Brazilian common opossum respectively. There was no difference between the right and left eye neither sex. A significant difference was obtained for the same test to different species. No significant correlation was found between the tests for both species. The description of tear production parameters for juvenile white-eared opossum and Brazilian common opossum may be used as a tool, which will allow the early diagnosis of ocular diseases.
Effect of Flange Width-Thickness Ratio on Eccentrically Braced Frames Link Cyclic Rotation Capacity

An analytical study was conducted to investigate the influence of the flange width–thickness ratio on the rotation capacity of links in eccentrically braced frames. Finite element models, verified using experimental data, were used to investigate the performance of 112 links. Models simulated strength degradation associated with flange and web local buckling that may occur during cyclic loading. The models provided data for short, intermediate, and long links with a range of flange width–thickness ratios. Results indicate that a relaxation of the flange width.thickness ratio requirement in current AISC seismic design provisions is justified. It was also found, however, that the provisions specify nonconservative design rotations for some intermediate links. This is shown to be related to web stiffener spacing and not the flange width–thickness ratio.
Calcification rate in Emiliania huxleyi Lohmann in response to light, nitrate and availability of inorganic carbon

SUMMARY The relationship between photosynthesis and calcification was investigated in a high-calcifying strain of Emiliania huxleyi. At pH 8.3 and a photon flux density of 50 μmol m−2 s−1 calcification and photosynthetic 14CO2 fixation were carbon saturated at 1 mM DIC (dissolved inorganic carbon) but at a photon flux density of 300 μmol m−2 s−1 calcification and photosynthetic 14CO2 fixation were not saturated at the DIC concentration of sea-water, 2 mM. When HCO3− provides the bulk of inorganic carbon the stoichiometry between photosynthetic 14CO2 fixation and calcification was 1:1. In the high-calcifying strain of E. huxleyi the stoichiometry between photosynthetic 14CO2 fixation and O2 evolution was 2:1 but in a low calcifying strain the stoichiometry was 1:1. High nitrate concentrations, i.e. 1000 μM were required to inhibit calcification. The optimum pH for calcification and photosynthetic 14CO2 fixation was 7.8. From the results a model is proposed in which a molecule of HCO3− is the precursor of calcite in the coccolith vesicle with the extrusion of H+ into the cytosol, while another HCO3− provides CO2 in the chloroplast with the extrusion of OH−. The interaction of these processes maintains cytoplasmic pH near neutrality.
AN INTEGRATED FRAMEWORK FOR POST-ISO 9000 QUALITY DEVELOPMENT

For both ISO 9000 and TQM concepts there have been many research programmes and publications. However, the coincidence of these topics and/or the ambiguity about their relationship has emerged in a number of discussions. This paper examines this relationship and provides a framework to assist manufacturing organisations to move beyond the requirements of ISO 9000 towards total quality. The research methodology adopted was based on extracting a conceptual model from the review of literature on ISO 9000, TQM, performance measurement and strategy. The conceptual model, provided the basis for the final framework, which was divided into two parts, “formulation” and “implementation”, as stages of post‐ISO 9000 quality development. The research empirically examined these stages by surveying over 200 industrial companies including 18 detailed case studies which produced a number of findings. The research findings have been integrated to form the post‐ISO 9000 quality development framework.
