An Improved SHM-PAM Technique for Three-Phase Five-Level CHB Inverter Utilizing Both Quarter-Wave and Half-Wave Symmetry Waveforms to Fulfill Some Important Voltage Harmonic Standards

Selective harmonic minimization-pulse amplitude modulation (SHM-PAM) generates a waveform that minimizes some selected low-order harmonics instead of eliminating them completely. This approach is highly beneficial for medium-voltage high-power inverters, where allowable amplitudes for individual harmonics (mentioned in power quality standard) are required with low switching frequencies. This work applies improved SHM-PAM proposing four new types of formulations utilizing quarter-wave (QW) and half-wave (HW) symmetry-based waveforms for three-phase five-level cascaded H-bridge (CHB) multilevel inverter (MLI) to satisfy the requirements of two well-known power quality standards, namely IEC 61000-2-12 and ER G4/5. Recently reported dragonfly algorithm (DA) is used for computing the optimum switching angles and dc-link voltages required to control the CHB MLI. The effectiveness and practicality of the proposed techniques have been investigated through extensive simulations and experimentation on a laboratory scale CHB MLI. While fulfilling the IEC 61000-2-12 and ER G4/5 voltage harmonic standards, the solutions provided by QW and HW symmetry-based waveforms are compared based on several performance indices such as waveform quality and power losses. It is found that HW symmetry waveforms provide better waveform quality and power loss profile than QW symmetry waveforms. The proposed SHM-PAM has also been compared with some existing modulation techniques to justify its mastery. Finally, the practicability of the proposed SHM-PAM technique is verified on an induction motor drive application.
RADIOLOGICAL ASSESSMENT OF GRAINS, VEGETABLES, FRUITS AND TUBER CROPS CULTIVATED IN OKEMESI TOWNSHIP, EKITI STATE, NIGERIA

Exposure to radiation is a natural phenomenon in the human environment. This is received from naturally occurring radionuclides in water, air, soil and food. Ingestion is one of the two major pathways through which these nuclides enter the human systems. Radiological assessment of fruits, vegetables, grains and tuber crops cultivated and consumed in Okemesi township, Ekiti State has been carried out using a 76mm by 76mm lead-shielded Sodium Iodide detector (NaI(Tl)) located at the Centre for Energy, Research and Development (CERD), Obafemi Awolowo University, Ile-Ife, Nigeria. The mean activity concentration of the radionuclides in the food samples was 155.76 ± 14.22 Bqkg-1 for 40K, 8.00 ± 0.24 Bqkg-1 for 238U and 7.39 ± 0.21 Bqkg-1for 232Th.The value obtained for Annual Effective Dose due to intake of the food crops (Ding) ranged from 104.32 to 687 µSv yr-1 while values for Excess Lifetime Cancer Risks (ECLR) ranged from 0.365 t0 2.407. Although the radioactivity levels in the food crops were lower than the world-wide limits, some values obtained for the AED and the ELCR were significantly higher than the recommended limits of UNSCEAR 2000. The rank order of Ding and ELCR in the food types was tubers ? fruits ? vegetables ? grains. Consumption of food cultivated in the area over a long period of time may induce a degree of health risks which should not be overlooked.
Users' Perceptions of Personal Control of Environmental Conditions in Sustainable Buildings

Abstract As part of a broader assessment of the performance of a worldwide set of sustainable buildings, the authors investigated the users' perceptions of personal control of internal environmental conditions. The main aims were to determine the amount of personal control building users had over heating, cooling, ventilation, lighting, and noise; and whether they considered it to be important. A questionnaire survey, in which respondents rated these various aspects on a 7-point scale, was the principal instrument used. For this set of buildings it was found that the users' perceived the amount of personal control they had of lighting to be reasonable, but that for heating, cooling, ventilation, and (particularly) noise was relatively low. Around 30% of respondents see it as important to have this control. Some of the findings suggest that the better the users' perceptions of their environmental conditions, the less their apparent need for personal control, a line of enquiry possibly meriting further pursuit. A number of findings reinforced the conclusion that noise problems remain a real concern.

Financial literacy in Italy: Empirical evidence and theoretical proposals

The purpose of this book is to analyse financial literacy from theoretical and empirical points of view, with a particular focus on the evidence related to Italy. This work is motivated by the increasing complexity of financial instruments as well as by the evolution of individuals’ needs that result in the need to implement measures to increase individuals’ financial literacy. Since financial literacy level seems to determine an individual’s position in the financial system relative to other economic agents, financial illiteracy or the lack of financial knowledge and skills can lead to lifelong financial hardships (Lusardi & Mitchell, 2011). In this regard, a sufficient degree of financial literacy is a necessary condition for financial welfare (Lusardi & Mitchell, 2011).

Computer-Based Design Synthesis Research: An Overview

One of the hallmarks of engineering design is the design synthesis phase where the creativity of the designer most prominently comes into play as solutions are generated to meet underlying needs. Over the past decades, methodologies for generating concepts and design solutions have matured to the point that computation-based synthesis provides a means to explore a wider variety of solutions and take over more tedious design tasks. This paper reviews advances in function-based, grammar-based, and analogy-based synthesis approaches and their contributions to computational design synthesis research in the last decade.
The Effect of Perceived Usefulness, Perceived Ease of Use, and Social Influence on the Use of Mobile Banking through the Mediation of Attitude Toward Use

Mobile banking is one of the channels of banking service provided by banking institutions in forms of modern platforms that are fully based on digital technology and displace physical interaction between banks and their customers. For banking industry, mobile banking is more than a service option; it is a strategic plan to facilitate customer’s changes in behavior. However, the acceptance of such platform by the public, particularly micro entrepreneurs, is still in question. The objective of this research is to identify factors influencing the use of mobile banking based on the perception of micro customers of Bank DKI in Surabaya. The variables used in this study were developed from previous researches that also examined the same matter with adjustment on the characteristics of micro customers. The variables, developed through the theoretical review, were then empirically assessed using SEM-PLS. the data was collected from questionnaires distributed to 266 micro customers who received financing from Bank DKI. The surcey discovered that perceived usefulness, perceived ease of use, and social influence are empirically proven to have both direct effects on the use of mobile banking and indirect effects through attitude toward use. Practical implications also discussed in this paper.
Internet-Based Psychotherapy Intervention for Depression Among Older Adults Receiving Home Care: Qualitative Study of Participants’ Experiences

Background Depression is common among homebound older adults. Internet-based cognitive behavioral therapy (iCBT) is a promising but understudied approach for treating depression among older adults with disabilities. Objective This study aims to understand the experiences of homebound older adults who participated in a pilot feasibility trial of an iCBT for depression. Methods The participants included 21 homebound older adults who participated in a generic iCBT program that was not specifically designed for older adults and 8 home care workers who assisted in the iCBT program. Informants completed semistructured individual interviews, which were transcribed verbatim and analyzed using methods informed by grounded theory. A hierarchical code structure of themes and subthemes was developed after an iterative process of constant comparisons and questionings of the initial codes. The data analysis was conducted by using dedoose, a web app for mixed methods research. Results Three themes and various subthemes emerged related to participants’ experience of the iCBT intervention, as follows: intervention impact, which involved subthemes related to participants’ perceived impact of the intervention; challenges and difficulties, which involved subthemes on the challenges and difficulties that participants experienced in the intervention; and facilitators, which involved subthemes on the factors that facilitated intervention use and engagement. Conclusions iCBT is a promising intervention for homebound older adults experiencing depression. Home care workers reported improved relationships with their clients and that the program did not add a burden to their duties. Future programs should involve accessible technical features and age-adapted content to improve user experience, uptake, and adherence.

Mechanical stress caused frequency drift in cryogenic sapphire resonators

By comparing the drift rate between two nominally identical resonators, each with a choice of two closely spaced modes having a different electromagnetic configuration (E mode and H mode), it was found that variation of mechanical stress in the sapphire element induced by its mounting structure was the origin of the frequency drift of UWA 6 K sapphire oscillator reported previously. Discussions on the previously proposed mechanisms accounting for the oscillator residual frequency drift and measurement results on the relative frequency drift rate between a pair of resonators with different mechanical mounting structures are presented.
The Effect of COVID-19 on minor dry bulk shipping: A Bayesian time series and a neural networks approach

ABSTRACT Supply chain is a crucial part of the world economy and everyday life. During the outbreak of COVID-19 in 2020, governments across the globe have tried to maintain the supply chain operations in most of the essential goods and services. Dry bulk shipping, a sector characterized by trading versatility and a multitude of cargoes carried, has an important role to play towards that aim. Port restrictions, placed to limit the spread of COVID-19, have created the impression that the market of dry bulk shipping has, to some degree, been affected and become less predictable, as many other transporting services. In this article, this belief is investigated using both state space modeling and neural networks. In particular, using these methods, one-month ahead predictions (during 2020) of the overall freight cost are obtained for three types of vessels (representing the majority of the minor bulks industry). A good forecast performance is observed and this validates the models and the estimation methods proposed. Our results suggest that there is no significant effect of COVID-19 in these types of vessels and their operations. This can provide useful information to shipping managers and policy makers.
Parametric Study of Longitudinal Seismic Pounding Response for RC Girder Bridge Based on Kelvin Impact Model

The pounding between adjacent segments of bridge has significant influences on its seismic performance, which is a complex nonlinear phenomenon involving many parameters. Based on Kelvin impact model, a simple-supported girder bridge was introduced to discuss the effects of impact stiffness and initial gap between joints. With dynamic analysis, it can be drawn the reasonable range for impact stiffness ratio and initial gap at expansion joint are respectively 0.05~0.2 and 0.04m~0.05m, which make the earthquake response of bridge reach a good balance.
Surveillance of milk adulteration and its impact on physical characteristics of milk

An experiment was designed to screen the various adulterants in the market milk sold in the coastal area of Sindh province during the year 2014. A total of 100 milk samples were collected each of twenty (n= 20) from milk producers, milk collectors, middlemen, processors and dairy shops at the vicinity of Badin brought in the Department of Animal Products Technology, Faculty of Animal Husbandry and Veterinary Sciences, Sindh Agriculture University Tandojam, Pakistan. Among all milk samples water (76%) was the common adulterant found to be in the majority of milk samples evaluated in present study, followed by detergent (25%), rice flour (22 %), caustic soda (18%), salt (17%) and cane sugar (14%), respectively. The extent of extraneous water in milk samples collected from dairy shops, middlemen and milk collectors was significantly (P˂0.05) high than that of samples collected from processor and milk producer. The proportion of adulteration at all the milk intermediaries was (P˃0.05) non significant. The pH value of all milk samples collected from different marketing channels was significantly (P˂0.05) different from each other except in samples collected from dairy shops and middlemen. Significant difference (P<0.05) was observed in freezing point of milk samples collected from all milk marketing channels. The specific gravity of milk samples collected from all milk marketing channels was found to be significant (P<0.05) with each other.

Fiber-optic Fabry-Perot interferometers are applied to the sensors of temperature, mechanical vibration, acoustic wave including human voice, ac voltage, and ac and dc magnetic fields. It has been demonstrated that a fiber-optic Fabry-Perot interferometer can simplify the interferometric fiber sensor sys-tem and that high measurement sensitivity can be obtained by using a high-finesse and/or long-distance fiber Fabry-Perot interferometer.
An Interactive Methodology for Axial Compressor Design Teaching

The implementation of new technology in the gas turbine industry is accelerating at a rate which demands increasing specialisation by its engineering design staff. Simultaneously, this industry has been adopting concurrent engineering practices to reduce product lead-time. Accordingly, the industry now requires its engineers to acquire early competence in a wide range of technological disciplines. In addition, the individual must have a thorough understanding of the impact of component design decisions on both other components and on the engine as a whole.Against this background, gas turbine educational providers must respond to these increasing demands with teaching programmes that facilitate a faster and deeper understanding of this very complex product. The ambition of the teacher, however, to adequately prepare the student will continue to be limited by time constraints within lecture courses. Hitherto, this has normally resulted in class worked examples which are necessarily narrow in scope and confined to a limited range of design cases.This paper describes a teaching methodology which is structured to facilitate in-depth understanding of the key interactions between aerodynamics, thermodynamics and mechanical integrity arising in axial compressor design optimisation. This is achieved interactively through a combination of lectures, a hand worked multistage preliminary compressor design, a series of personal computer based design optimisation workshops and a final collective design assessment.Copyright © 1999 by ASME
TQM and Environmental Excellence in Manufacturing

Recent public policy trends and new consumer demands are redirecting the attention of management outside the traditional focus of customers, suppliers and internal operations. However, little research has focused on the perspective that operations management and the growing body of literature on total quality management can offer much on the environmental management of operations. Investigates the potential link between the concept, approach, methodology and benefits of total quality management (TQM) and environmental excellence in operations management. Proposes a hierarchical model for the development of environmental excellence. Environmental management has become strategic and the integration of the design, production, delivery, circulation, use and disposal of products is necessary to achieve improved environmental performance. Second, by including environmental factors in the integrated training of the workforce and the reward structure of the firm, long‐term continuous improvement is possible. Like.
Modeling and Analysis of HetNets With Interference Management Using Poisson Cluster Process

In typical wireless heterogeneous networks (HetNets), users are clustered around known hotspots, e.g., shopping centers or schools, but such a non-uniform distribution of nodes is difficult to analyze. This paper explicitly models this scenario, with macro base stations (MBSs) modeled by a homogeneous Poisson point process (PPP), and millimeter-wave small base stations (mmWave SBSs) and users clustered around the hotspot centers, forming two Poisson cluster processes (PCPs), respectively. Fractional frequency reuse (FFR) and coordinated multi-point transmission (CoMP) are assumed since they help to limit the co-tier interference and enhance the coverage and capacity of the network. We present a distance-based approach for grouping macro user equipments (MUEs) from the cell center (CC) and cell edge (CE) regions for FFR analysis. We first derive some distance distributions, including joint distance distribution from the typical user to the cooperative open-access mmWave SBS and distance distribution from the typical user to the non-cooperative open-access mmWave SBS. We obtain expressions for various performance metrics, including association probability, signal to interference-plus-noise ratio (SINR) coverage probability, and ergodic capacity, under these conditions. Due to the complexity of the exact expressions, we derive novel approximations, using Alzer's lemma, to obtain the lower bounds on coverage and ergodic capacity, which are shown to be accurate through Monte Carlo simulation. Simulation results analyze the effect of different parameters on the network performance to give some guidance for the design of future networks. Numerical optimization of a key parameter, in terms of association probability, coverage probability, and ergodic capacity, is enabled by our analysis.
WATER DROPLET DYNAMICS AND EVAPORATION IN AN IRRIGATION SPRAY

A new approach to droplet evaporation in sprinkler irrigation is presented. A theoretical description is provided and experimental results are shown, proving that some knowledge previously accepted by the scientific community could be less than certain. This article describes three directions of investigation: two theoretical and one experimental. A mathematical model based solely on a dynamic approach achieved results similar to those of far more complicated models, and application of the model demonstrates that, until now, air friction may have been wrongly neglected in computing droplet evaporation. In addition, experimental tests prove that air temperature has a significant effect on droplet evaporation. The three sets of results open a new direction for research on this topic and provide challenges for future investigations.
Impact of oyster culture on coral reef bacterioplankton community composition and function in Daya Bay, China

: Subtropical coral reefs along the coast are facing multiple pressures. Mariculture is one of the main sources of such pressure. Oyster culture has become a worldwide phenomenon in coastal ecosystems. Due to the high filtration efficiency of oysters, their culture has helped to purify some coastal waters. However, high-density oyster culture has also had negative effects on coastal ecosystems, including the loss of natural habitat, changes in hydrology, cross infection of corals with pathogenic bacteria, and changes to the structure and function of bacterioplankton communities. In this study, the effect of oyster culture on coral reefs was characterized based on variability in the structure and function of bacterioplankton communities. Using 16S rRNA gene sequencing, a comprehensive bacterioplankton reference database was constructed for coral reef habitats associated with oyster culture and subjected to different disturbance gradients. Small shifts in the surrounding coral reef environment caused by oyster culture disturbance were detected by comparing the structure and function of bacterioplankton communities with biogeochemical parameters. The measured chemical dynamics explained 71.15% of the bacterioplankton community variability between habitats. Oyster culture increased the richness and diversity of bacterioplank-ton communities. Species composition similarity was highest between the oyster culture area and the nearest coral reef habitat. The spatial turnover in the bacterioplankton community was characterized by less uniform community assembly patterns. The bacterioplankton function of reefs relatively far from anthropogenic disturbance differed from that of those closer to such disturbances. Our results also show that the variability in structure and function of bacterioplankton communities between oyster culture areas and coral reef areas was mainly driven by salinity and ammonium. Oyster culture can impact bacterioplankton community composition and dynamics around coral reef habitats. The results provide an important context for developing frameworks for managing ecological interactions among oyster cultures and coral reef habitats of concern
