How to Leverage Mobile Vehicles to Balance the Workload in Multi-Access Edge Computing Systems

In this correspondence, we investigate the joint relay and server selection problem for a novel vehicle-assisted multi-access edge computing (MEC) system, where vehicles on the road relay data from an end device to appropriate MEC servers for computing in a store-carry-forward manner. To harness the stochastic nature of task arrivals, vehicle availability, and resource availability at MEC servers, we design a relaying scheme to minimize the average task latency based on a Markov decision process. Our study shows that our proposed scheme is highly effective in balancing the communications and computing while minimizing the end-to-end latency for task completion.
Multitask Performance: Predicting Success in Naval Aviation Primary Flight Training.

Abstract : A multitask experiment simulating certain motor control and communication requirements characteristics of flight was conducted to determine relative strengths of several performance measures as predictors of primary flight training success. A Psychomotor Task (PMT) and a Dichotic Listening Task (DLT) performed under single-task conditions were found to be significantly related (p less .05) to a primary flight training pass/fail criterion. Two separate multitask DLT measures also correlated with the pass/fail criterion and at higher levels of statistical significance (p less than .01) than the single- task measures. The results indicate that various single- and multitask measures are significantly related to primary flight performance, and further reveal that the component test measures may be better predictors under multitask than under single-task conditions. Additional research using larger samples and additional multitask tests is indicated.
Developing a model that defines the relationship between a performance measurement system and other organisational entities

Many articles have been written on the design and implementation of performance measurement systems. In this regard literature also indicates the high failure rate associated with implementation. When the various issues assigned to failure are analysed, a number of these issues can be categorised as systemic issues. This research defines these systemic issues as contextual issues – those issues outside of a performance measurement system, yet having an impact on its functioning and performance as a system. This research explains how systems theory was used to construct a model that defines twelve contextual entities, seen as key entities influencing the functioning of a performance measurement system. These twelve entities are organisational culture, management commitment and support, information architecture, performance measurement process owner, overall status of IT/IS, organisational structure, evaluation process and information flow, performance management system, strategic planning process, policies and procedures, “other” measurement processes, and resources. The model also defines the relationship between each of these entities and a performance measurement system. When the model is applied in practice it determines the strength of the relationship between each entity and a performance measurement system. Based on the strength of each relationship, an organisational learning experience is created that provides a perspective on the performance measurement readiness of an organisation. This study focuses on strengthening the relevancy and applicability of the model by applying the model at two public universities in South Africa. The specific research focus was to generate an understanding of whether different contexts prompted any changes to the model. The research concludes by indicating that context changed the model in minor ways and also that the universities perceived the model to be relevant. Based on these findings stronger claims can thus be made in terms of the model’s relevancy and applicability.
Molecular dynamics simulations of AlN deposition on GaN substrate

ABSTRACT In this work, we investigated the deposition of AlN film on GaN substrate by using molecular dynamics (MD) simulations. The effects of GaN substrate surface, growth temperature, and injected N: Al flux ratio on the growth of AlN film were simulated and studied. Consequently, the deposited AlN film on the (0001) Ga-terminated GaN surface achieves better surface morphology and crystallinity than that on the (000-1) N-terminated GaN surface due to the different diffusion ability of Al and N adatoms on two GaN surfaces. Furthermore, with the increase of growth temperature, the surface morphology and crystallinity of AlN film were improved owing to the enhanced mobility of adatoms. At the optimised injected N: Al flux ratio of 1, comparatively good surface morphology and crystallinity of deposited AlN films were realised. This method lays a foundation for the follow-up real-time study of defects and stress evolution of AlN on GaN and can be applied to film growth of other materials. GRAPHICAL ABSTRACT

Advanced Control Strategies to Enable a More Wide-Scale Adoption of Single-Phase Photovoltaic Systems

The installations of PhotoVoltaic (PV) systems, including grid-connected PV systems, have experienced a significant increase in the past few decades. More PV capacity is expected for the future power grid to be of intelligence and flexibility. This thriving scenario also raises concerns about the availability, quality and reliability of the whole power grid. Consequently, grid codes/standards are continuously being revised to host more PV energy in the grid. Ancillary services required initially by wind power systems, e.g. fault ride-through and grid support, are becoming more preferable in PV systems today than they were. In addition, achieving high efficiency and high reliability is always of importance for PV systems in order to reduce the cost of energy. Both goals can be enabled by advanced control strategies for PV systems, which are typically based on power electronics technology. In the light of those issues, the Ph.D. project has investigated and evaluated next-generation transformerless inverters for single-phase grid-connected PV systems, and proposed advanced control strategies to enhance the PV penetration with reduced cost of energy. The research work mainly includes two parts: 1) Modelling and Evaluation of Single-Phase PV Systems and 2) Advanced Control Strategies for Single-Phase PV Systems. The first part, including Chapters 2 and 3, describes the entire models of the most promising transformerless PV candidates (models of PV modules, inverters, and filters) in Chapter 2. Then, a thorough evaluation of those topologies in terms of e.g. efficiency, reliability, leakage current mitigation ability, and reactive power injection capability has been presented in Chapter 3, where a multidisciplinary assessment approach with characterized features of energy production estimation and lifetime prediction based on mission profiles (e.g. solar irradiance level and ambient temperature) has been proposed. Grid detection and synchronization techniques have also been discussed in Chapter 2, since they are of importance in the control of single-phase systems both in normal operation mode with maximum power point tracking and under grid faults. According to those investigations, advanced control strategies, which are able to ensure a flexible, reliable and efficient power conversion from PV systems in different operation modes, have been proposed and implemented in Chapters 4 to 6. The first discussed advanced control strategy is about the low voltage ride-through control of
Selecting Particle Counters for Process Monitoring

Instruments that simultaneously count and size individual particles can be used for analyzing raw-water particulates, optimizing chemical dosages, measuring particulates in fiter effluent, determining filter efficiency in terms of percent removal of particles, and many other applications. A single particle counter will not, however, be universally applicable to all of these circumstances. The type of particle counter required will be determined by the types of water samples to be analyzed and the ultimate use of the data.
Antennas using left handed transmission lines

The research described in this thesis is concerned with the analysis and design of conventional wire antenna types, dipoles and loops, based on the left-handed transmission line approach. The left handed antennas have a unique feature that the wavelength of the induced current becomes shorter with decreasing frequency. The left handed transmission line concept can be extended to construct reduced-size dipole or loop antennas in the VHF frequency band. The use of higher order modes allows orthogonal polarisation to be obtained, which is thought to be a feature unique to these antennas. Efficiency is a key parameter of left handed antennas as the heavy left handed loading increases the resistive loss. A study of the efficiency of small dipole antennas loaded with a left-handed transmission line is specially described, and the comparison with conventional inductive loading dipoles. In a low order mode, the efficiency of L-loading dipole is better with low number of unit cell. If the number of cell increases, CL-loading presents comparable and even better performance. In a high mode the meandered left handed dipole gives the best efficiency due to the phase distribution, presenting orthogonal polarization as well. The optimized dipole loaded with parallel plate capacitors and spiral inductors presents the best performance in impedance and efficiency, even better than the conventional inductive loading. A planar loop antenna using a ladder network of left handed loading is also presented. Various modes can be obtained in the left handed loop antenna. The zero order mode gives rise to omnidirectional patterns in the plane of the loop, with good efficiency. By loading the loop with active components, varactors, a tunable left handed loop antenna with a switchable radiation pattern is implemented. The loop gives an omnidirectional pattern with a null to z axis while working in an n = 0 mode and can switch to a pattern with a null at phi = 45° in the plane of the loop in an n = 2 mode.

Minor fall and major lift: raising educational capacity through community partnerships

This transdisciplinary study explores holistic models of education and community development. It looks at transformations that occur when parents undertake tertiary education in two High Schools in a community with a high multi-cultural youth population. Engaging in interviews and focus groups, participants give narrative accounts providing rich qualitative data. Effective pedagogy is analysed in this Community Skills Certificate course on Identity and Communication. The research seeks practical solutions to barriers to social and educational progress in the students’ lives. It ascertains improvement in interpersonal relationships, including parenting skills. In addition, it looks at changes in family attitudes toward education that facilitates increased career opportunities. This work suggests that building local capacity through educational partnerships and effective pedagogy empowers individuals and the community. Families and employees are able to function more effectively as they apply newly learned intrapersonal and interpersonal skills. The study juxtaposes constructs of fall and lift – socially, educationally and psychologically. Belief in agency and transformational pedagogy is central to this study’s argument that through the cracks of disadvantage holistic alternatives emerge. COMMUNITY PARTNERSHIPS 3
Modeling Treated LAW Feed Evaporation

This task examines the potential of the treated waste feed blends to form sodium-aluminum silicate precipitates when evaporated using the zeolite database. To investigate the behavior of the blended pretreated waste feed, an OLI Environmental Simulation Package Software (OLI ESP) model of the treated low activity waste (LAW) evaporator was built. A range of waste feed compositions representative of Envelope A, B, and C were then fed into the OLI model to predict various physical and chemical properties of the evaporator concentrates. Additional runs with treated LAW evaporator were performed to compare chemical and physical property model predictions and experimental results for small-scale radioactive tests of the treated feed evaporation process.
An Experimental Study on the Effect of Introducing Sound In the City Riversides for Soundscape Application

It is very difficult to reduce ambient noise level in the downtown. The best method is to improve the sound amenity of the districts, considering concept of soundscape. This study aims to survey the effect of introducing sound and masking to reduce the background noise level. We carried out the evaluating test for 18 introducing sounds varied S/N ratio(-5, 0, +5) in the city riverside. In these test, subjects evaluated the sound environment with five bipolar adjective scales. It was evaluated that introducing sounds improved the sound environment, and that S/N +5 dB was very appropriate to mask the background noise. But the hearing level was suggested to be S/N 0 dB or less.
Finite Element Modeling and Exploration of Double Hearing Protection Systems

Abstract : Noise levels in modern industrial and military environments are constantly increasing, requiring the improvement of current hearing protection devices. The improvement of passive hearing protection devices lies in examining the performance of major contributors to reduction of noise attenuation. The finite element method can be used to fully explore single hearing protection (SHP) and double hearing protection (DHP) systems, and the major performance mechanisms can be observed numerically as well as visually in modern postprocessing software. This thesis focuses on developing and evaluating double hearing protection finite element models, and exploring the behavior mechanisms responsible for reduced noise attenuation. The double hearing protection model studied consists of an earmuff preloaded to a barrier covered to simulate human flesh, and a foam earplug installed inside a rigid cylinder designed to simulate the human ear canal. Pressure readings are taken at the bottom of the simulated ear canal assembly. Advanced finite element models are used to reconcile differences between the experimental and finite element results, and to investigate the behavior of the modeled system. The foam earplug material properties for the finite element model are required in the same shear state of stress and boundary condition configuration as the experimental DHP setup, therefore a novel material extraction method is used to obtain this data. The effects of radial compression preload on the earplugs are considered, and the resulting foam earplug shear material properties are input into the finite element DHP model where the effects of the updated foam material properties are observed.

Periodontal Evaluation of One-Piece and Two-Piece Single Implant Loaded in Esthetic Zone

Background : Soft tissue around dental implant is an important anatomical feature contributing to the long-term implant success and esthetics, different factors may influence the soft tissue-implant interface. The purposes of the current study were to evaluate the soft tissue profile around one-piece and two-piece implants loaded in esthetic zone. Method : Totally thirty patients who had single missing tooth in premaxillary region were included in the study. Fifteenth patients’ group-A were assigned to immediate loading one-piece implant and fifteen patients’ group-B were assigned to early loading two-piece implant protocol. Flapless approach was performed for both groups. In group-A, implants were loaded immediately with a temporary crown within 48h, while group-B, were loaded after two months following conventional impression for metal ceramic crown. Clinical outcomes were evaluated after two and six months in terms of success rate, papillary index, plaque index and width of keratinized mucosa. Results : The success rate in group-A found to be 80%, which was lower than the success rate in group-B (100%). On comparison, there was no statistically significant difference in success rate between the two study groups. There was no statistically significant difference between both groups over time in clinical parameters like plaque index, width of keratinized gingiva and papillary index. Conclusion : The results of this study indicated that using either immediately loading one-piece implants or early loaded two-piece implants protocol demonstrated the same enhancements of implant esthetics.
High SPAG5 Expression Is Associated With Oncological Features in Endometrial Carcinoma

Sperm-associated Antigen 5 (SPAG5, also called astrin) is a mitotic spindle protein. SPAG5 has emerged as a promising biomarker and therapeutic target in a variety of cancers. However, its expression and role in endometrial cancer (EC) remain to be studied. Using multi-omic authoritative datasets from the TCGA and CPTAC studies, we characterized theexpression, regulation of SPAG5 and its association with clinicopathological and molecular features in EC. SPAG5 was observed to be overexpressed in tumor tissues compared to controls and receiver operating characteristic analysis suggested that its mRNA levels are an excellent predictor of tumor presence (AUC>0.98). SPAG5 overexpression was associated with serous histology and The Cancer Genome Atlas (TCGA) defined molecular subtypes. Analysis of DNA methylation levels at SPAG5 genomic regions exhibiting negative correlation to SPAG5 expression. Further, SPAG5 expression was associated with copy number gain in EC. Univariate and multivariate survival analysis revealed that higher SPAG5 expression was independently associated with poor patient outcomes in EC. Additionally, gene set enrichment analysis of SPAG5 correlated genes revealed its association with numerous oncological pathways which suggest its critical involvement in this malignancy.

Transmitting Sensitivity Enhancement of Piezoelectric Micromachined Ultrasonic Transducers via Residual Stress Localization by Stiffness Modification

Residual stress dramatically affects the performance of piezoelectric micromachined ultrasonic transducers (pMUTs), in particular, the transmitting sensitivity. This letter presents a novel architecture for pMUTs with V-shaped springs. Stiffness modification achieved by the V-shaped springs contributes to localize the residual stress, resulting in a flat vibrating membrane rather than a curved one. The experimental results show that the initial deflection of the vibration membrane is less than 10 nm or 0.004% (deflection/membrane size) for the enhanced pMUT. Leveraging on the flat vibrating membrane, the transmitting sensitivity of the enhanced pMUT is 50.9 nm/V, which is 203% higher than the pMUT without springs. Combining with the piston-like mode shape, the output sound pressure of the pMUT can be improved by around 23 dB.
