Bacterial Foraging Based Optimal Design of Transverse Flux Linear Motor for Thrust Force Improvement

Abstract—This article presents a novel optimal design for a permanent magnet excitation transverse flux linear motor with an inner mover using bacterial foraging optimization. The target is maximizing the motor thrust force, which is the most important quantity in linear electric drives. The stator pole length, air-gap length, winding window width, and stator pole width define the search space for the optimization problem. The response surface methodology is used to build the mathematical model of the motor thrust force in terms of the design variables. It can create an objective function easily, and great computational time is saved. Finite-element computations are used for numerical experiments on the geometrical design variables to determine the coefficients of a second-order analytical model for the response surface methodology. The bacterial foraging optimization technique is used as a searching tool under the constraints of design variables for design optimization of the transverse flux linear motor to improve the motor thrust force. The effectiveness of the proposed bacterial foraging optimization model is then compared with that of both genetic algorithm and particle swarm optimization models. With this proposed bacterial foraging optimization technique, the thrust force of the initially designed transverse flux linear motor can be increased.

Why are accurate computations of mode fields in rectangular dielectric waveguides difficult

The electric field of the modes of rectangular dielectric waveguides is known to diverge in the corners of the waveguide. An accurate numerical computation of the vector mode fields for a sample waveguide exhibits clear signs of this divergence. The divergence makes the design of rapidly converging numerical algorithms for vector mode field computations difficult. >
Acoustic testing of avocado for fruit ripeness evaluation

An acoustic method for nondestructive testing of avocado fruits was developed in order to determine the fruits’ firmness index, internal damping and the centeroid of the frequency response. The method is based on mechanical impulse excitation and flexible piezoelectric sensors. Emphasis was made on the engineering aspects of the method. The effects of the fruits’ irregular shape on the consistency and the variability of the test results were examined. A comparison was made between the acoustic tests and destructive penetration tests during storage. The damping ratio, which indicates fruit ripeness, increased monotonically with storage time, while the resonant frequencies and the firmness index decreased with time. A correlation coefficient R = 0.659 to 0.806 was found between the acoustic parameters and the maximum penetration force. A method is suggested to construct a ripening curve of fruits according to their “biological age”.
Brisbane's digital strategy: an economic strategy for the digital age?

A growing number of cities around the world have now realised the need to use digital technology to capitalise on the rapidly growing digitally driven economy. In mid-2013 Brisbane, Australia released its ‘Digital Strategy’ document to strengthen its economy through improved productivity for local businesses. The article is based on a combination of policy analysis and empirical data gathered through interviewing a sample of stakeholders involved in the strategy development process. It aims to understand how Brisbane intends on using the potentials of the digital economy. The results raise questions around the role defined for the digital economy in the future and shed light on the ‘smart city’ concept as a plausible digital-enabled direction for cities and regions with reference to the third wave of economic development, and the Triple (Quadruple) Helix of knowledge development. The lessons learned here may be applicable to any city interested in playing a proactive and productive role in the new economy.
PROJECT IMPACTS OF SPECIALTY CONTRACTOR DESIGN INVOLVEMENT IN THE HEALTHCARE INDUSTRY: A COMPARATIVE CASE STUDY

Due to rising energy costs and increasing attention to indoor environmental quality, the application of sustainable practices in healthcare facilities is gaining momentum. While the market for sustainable healthcare facilities is still developing, initial research indicates that an integrated design process, involving multiple disciplines and specialty contractors early in project development, is beneficial to implementing sustainable goals or strategies at a reasonable initial cost. This research performed a comparative case study of two projects, using existing project-level performance metrics, to identify causal relationships between integrated mechanical system delivery and project outcomes. Case A was a large design-build healthcare facility, comprised of a combination of outpatient clinic and inpatient hospital spaces, and engaging the mechanical contractor for both design and construction services. Case B was similarly specified large healthcare facility, but was delivered with a CM at risk organizational structure and involved the mechanical contractor in a design-assist role later in the overall design process. Both cases have strong similarities in project attributes, which establish a reference point and reduce the likelihood of external explanations for measured outcome differences between projects. Consistent with expectations from previous delivery method research, the project-level outcomes revealed design-build with less measured cost and schedule growth than CM at risk. Quantitative results also indicated that outcomes measured at the mechanical contractor-level were reasonable predictors of project-level outcomes in a design-build organizational structure. However, when the design and construction responsibilities were contractually separated, as in Case B, contractor and project performance outcomes appeared more divergent. From a causal perspective, the alignment of design and construction incentives, pacing of design deliverables with construction activities and completeness of the owner programming requirements all contributed to improved cost and schedule predictability. Additionally, contracting the mechanical contractor with fixed price design and construction responsibilities showed unique potential for increasing projected energy savings and improving jobsite safety for the building. These results highlight the effects of combining a design-build organizational structure, an incentivized contract, high owner commitment and high team commitment toward improving the delivery of sustainable healthcare facilities.
Earthquake Damage to Industrial Facilities and Development of Seismic and Vibration Control Technology

This paper reviews the situations and features of earthquake damage to industrial facilities, manufacturing companies, energy supply facilities, and mechanical structures and installations in Japan, and traces trends of countermeasure technology developed focusing on earthquake resistance and vibration control. In Japan, with the 1964 Niigata earthquake as the turning point, earthquake damage to industrial facilities became a social problem. With power stations being constructed in the 1960s, it also became an important technological policy to establish seismic design method for nonbuilding structures such as equipment and piping systems related to nuclear power. The Kobe earthquake in 1995 damaged production companies including leading manufacturers so extensively that it brought a new focus to seismic considerations. We studied the damage to typical equipment and installations and, based on this experience, investigated the features of damage modes to industrial facilities and machinery and considered corresponding technical measures. We present some examples and discuss progressive trends in seismic and vibration control technology following the Kobe earthquake. In particular, we focus on the new seismic design code for high-pressure gas facilities and the development of seismic and vibration control dampers and their applications.
Reinjury Rates in Adolescent Patients 2 Years Following ACL Reconstruction

Background: Sports injuries have increased dramatically in the pediatric and adolescent population. Return-to-sport testing and criteria are increasingly utilized, however, the guidelines for return to play in adolescents are unclear. The purpose of this study was to compare strength and function at the time of the return-to-sport progression to those with and without a failed anterior cruciate ligament reconstruction (ACLR). Methods: A total of 105 adolescent patients with primary ACLR were assessed at the time of return to sport. We identified graft failures/contralateral injury through medical records, clinic visits, or phone interviews at minimum 2 years of postsurgical follow-up. All patients completed bilateral isokinetic strength tests of the knee extensor/flexor groups and hop tests. Strength was expressed as torque-normalized-to-mass (Nm/kg), and limb-symmetry-index was expressed as a percentage of the uninvolved limb’s strength. All patients completed outcome surveys. The χ2 analysis was used to compare failures between sexes and graft types. Independent sample t tests were used to compare knee extensor/flexor strength, symmetry, and hop test results between patients with and without secondary anterior cruciate ligament (ACL) injury. One-way analysis of variance was used to compare knee extensor/flexor strength and symmetry, hop test, and survey results between those (1) without secondary injury, (2) ACLR graft failure, and (3) contralateral ACL injury. Results: A total of 100 of 105 patients (95.2%) were included with 4±1.2 years of follow-up, with 28 (28%) sustaining subsequent injury (12% graft, 16% contralateral). Patients with graft failure demonstrated (1) stronger quadriceps strength (2.00±0.46 Nm/kg) compared with those with contralateral ACL injury (1.58±0.35 Nm/kg, P=0.039) and patients that did not have a secondary injury (1.58±0.44 Nm/kg, P=0.007), (2) greater quadriceps strength symmetry (85.7±0.11.2%) compared with patients without secondary injury ACL (72.9±17.9%, P=0.046), (3) a greater proportion of hamstring grafts compared with those without reinjury (P=0.028). Conclusions: Adolescent patients who sustained ACLR graft failure had greater and more symmetric quadriceps strength at the time of return to sport compared with patients with no secondary injury. Objective measures of quadriceps strength at the time of the return-to-sport progression may not solely identify individuals that have a secondary ACL injury. Study Design: Level IV—retrospective cohort study.
Proposal for a Localization System for an IoT Ecosystem

In the last decade, positioning using wireless signals has gained a lot of attention since it could open new opportunities for service providers. Localization is important, especially in indoor environments, where the widely used global navigation satellite systems (GNSS) signals suffer from high signal attenuation and multipath propagation, resulting in poor accuracy or a loss of positioning service. Moreover, in an Internet of things (IoT) environment, the implementation of GNSS receivers into devices may result in higher demands on battery capacity, as well as increased cost of the hardware itself. Therefore, alternative localization systems that are based on wireless signals for the communication of IoT devices are gaining a lot of attention. In this paper, we provide a design of an IoT localization system, which consists of multiple localization modules that can be utilized for the positioning of IoT devices that are connected thru various wireless technologies. The proposed system can currently perform localization based on received signals from LoRaWAN, ZigBee, Wi-Fi, UWB and cellular technologies. The implemented pedestrian dead reckoning algorithm can process the data measured by a mobile device that is equipped with inertial sensors to construct a radio map and thus help with the deployment of the positioning services based on a fingerprinting approach.
“Exemplary” teachers: The perception of prospective teachers of role model teachers and their contribution to their professional identity

This study examined the characteristics of “exemplary” teachers according to Israeli–Arab prospective teachers, and the influence of those perceptions on their professional identity. The study is based on the qualitative paradigm using in-depth semi-structured interviews with 33 students studying education in an academic college located in the center of Israel. Findings show that their professional educational identity begins to form while still at school, with exposure to an exceptional teacher in their past. The teacher’s digression from the traditional model of pedagogy in Arab education led them to the formulation of modern mindsets as educators and agents of change.
DESIGN AND VALIDATION USING FLIGHT DATA OF A METHOD FOR PREDICTING THE GROUND RUN REQUIRED FOR TAKE-OFF

The role of a take-off performance monitor is to determine whether the take-off manoeuvre is developing as desired or otherwise. Depending on design criteria, the system usually either compares the achieved performance against a pre-determined threshold, or else looks ahead and attempts to predict the future performance along the run. Whilst offering significant advantages over the former, the latter type relies on accurate prediction and the capability of looking as far ahead as possible to provide early warning of any impending anomaly to the crew. This paper discusses the predictive approach adopted in the design of a performance monitoring algorithm and presents the results obtained from flight testing using the College of Aeronautics’ Jetstream-100 flying laboratory.
GENETIC AND PHENOTYPIC TRENDS OF 305-DAY MILK YIELD OF HOLSTEIN COWS RAISED AT COMMERCIAL FARM IN EGYPT

The purpose of this study was to estimate the genetic and phenotypic trends of 305- day milk yield of Holstein cows in a commercial farm. Data consisted of 2654 lactation records for 850 Holstein cows sired by 316 sires, collected from 1991 to 2007. The data were analyzed using Least Squares technique to examine the effect of year, season of calving, parity and interaction between season of calving and parity factors on 305- day milk yield. Heritability of 305 day milk yield trait and breeding values were estimated using VCE 6.0. 2 software. Highly significant effects for year of calving, parity and the interaction between season of calving and parity on the 305- day milk yield were observed. However, season of calving had a non significant effect on the 305- day milk yield. The average of 305- day milk yield was 7042 kg. The heritability estimate of 305- day milk yield was 0.06. The regression of 305-day milk yield on year of calving showed a significant negative phenotypic trend being -91.6 kg per year. However, the genetic trend depicted a significant positive trend (+ 2.19 kg per year). In conclusion, although the trend in the estimated breeding values found for cows was positive, it still did not lead to change in the average milk production due to the probable reduction in the nutritional and /or management conditions of the herd.
Effects of Structural Non-Linearities on Aircraft Vibration and Flutter

Abstract : Work on flutter prediction has always been based on the modal representation of the structure, which implies a linear model of the aircraft. A number of good results have been obtained, for many prototypes, using this method. Unfortunately, more and more difficulties have appeared during the last few years, both for aircraft carrying large stores and for light aircraft, where non-linear phenomena made it hazardous to use a linear approach. This paper presents a possibility for taking into account some non-linearities of the structure and their effect on flutter. It is considered to be an important milestone in accurate flutter prediction in complicated conditions.
A large reduction of direct aerosol cooling over Poland in the last decades

This paper presents an analysis of the long‐term (1982–2015) variability of aerosol optical properties, as well as aerosol and greenhouse gases (GHG) direct radiative forcing (RF) in central Europe on the basis of MERRA‐2 reanalysis and ground‐based observation. Calculations of longwave (LW) and shortwave (SW) RF were made with the use of the off‐line Fu‐Liou radiative transfer model and were preceded by the sensitivity study of the code's input parameters. Then, the long‐term mean as well as the annual variability for selected regions of aerosol optical properties and radiative forcing were analysed. The mean AOD trend was −0.056 ± 9% per decade and AOD was reduced by 48% between 1982 and 2015. While for 1982–1990 the trend per decade was −0.12 ± 20%, for 1991–2000 it was −0.17 ± 17% and only −0.02 ± 31% in the last 15 years (2001–2015). The trend of the aerosol radiative forcing (ARF) was 1.52 ± 0.12 W·m−2/10 year and 1.21 ± 0.19 W·m−2/10 year at top of the atmosphere (TOA) and at Earth's surface, respectively. The trend for GHG was significantly smaller and it equalled 0.27 ± 0.01 W·m−2/10 year at TOA and 0.17 ± 0.01 W·m−2/10 year at the surface. Changes in GHG and aerosol direct effect produced additional 3.2 ± 0.2 W·m−2 at TOA, which could be associated with the observed regional climate warming. The change of the direct aerosol effect was about 4 times the GHG RF. The influence of aerosol loading reduction on the radiation budget was significantly higher in the 1990s of the 20th century in comparison to the first decades of the 21st. The effect of aerosol reduction has significant impact on air temperature changes during warm season and negligible during winter.
An efficient hybrid evolutionary heuristic using genetic algorithm and simulated annealing algorithm to solve machine loading problem in FMS

In this paper, a machine loading problem in a flexible manufacturing system (FMS) is discussed, with bi-criterion objectives of minimising system imbalance and maximising system throughput in the occurrence of technological constraints such as available machining time and tool slots. A mathematical model is used to select machines, assign operations and the required tools in order to minimise the system's imbalance while maximising the throughput. An efficient evolutionary algorithm by hybridising the genetic algorithm (GA) and simulated annealing (SA) algorithm called GASA is proposed in this paper. The performance of the GASA is tested by using 10 sample dataset and the results are compared with the heuristics reported in the literature. The influence of genetic operators on the evolutionary search in GASA is studied and reported. Two machine selection heuristics are proposed and their influence on the quality of the solution is also studied. Extensive computational experiments have been carried out to evaluate the performance of the proposed evolutionary heuristics and the results are presented in tables and figures. The results clearly support the better performance of GASA over the algorithms reported in the literature.
Transcriptome Analysis of Jujube (Ziziphus jujuba Mill.) Response to Heat Stress

Heat stress (HS) is a common stress influencing the growth and reproduction of plant species. Jujube (Ziziphus jujuba Mill.) is an economically important tree with strong abiotic stress resistance, but the molecular mechanism of its response to HS remains elusive. In this study, we subjected seedlings of Z. jujuba cultivar “Hqing1-HR” to HS (45°C) for 0, 1, 3, 5, and 7 days, respectively, and collected the leaf samples (HR0, HR1, HR3, HR5, and HR7) accordingly. Fifteen cDNA libraries from leaves were constructed for transcriptomics assays. RNA sequencing and transcriptomics identified 1,642, 4,080, 5,160, and 2,119 differentially expressed genes (DEGs) in comparisons of HR1 vs. HR0, HR3 vs. HR0, HR5 vs. HR0, and HR7 vs. HR0, respectively. Gene ontology analyses of the DEGs from these comparisons revealed enrichment in a series of biological processes involved in stress responses, photosynthesis, and metabolism, suggesting that lowering or upregulating expression of these genes might play important roles in the response to HS. This study contributed to our understanding of the molecular mechanism of jujube response to HS and will be beneficial for developing jujube cultivars with improved heat resistance.
