Compact modelling in RF CMOS technology

With the continuous downscaling of complementary metal-oxide-semiconductor (CMOS) technology, the RF performance of metal-oxide-semiconductor field transistors (MOSFETs) has considerably improved over the past years. Today, the standard CMOS technology has become a popular choice for realizing radio frequency (RF) applications. The focus of the thesis is on device compact modelling methodologies in RF CMOS. Compact models oriented to integrated circuit (ICs) computer automatic design (CAD) are the key component of a process design kit (PDK) and the bridge between design houses and foundries. In this work, a novel substrate model is proposed for accurately characterizing the behaviour of RF-MOSFETs with deep n-wells (DNW). A simple test structure is presented to directly access the substrate parasitics from two-port measurements in DNWs. The most important passive device in RFIC design in CMOS is the spiral inductor. A 1-pi model with a novel substrate network is proposed to characterize the broadband loss mechanisms of spiral inductors. Based on the proposed 1-pi model, a physics-originated fully-scalable 2-pi model and model parameter extraction methodology are also presented for spiral inductors in this work. To test and verify the developed active and passive device models and model parameter extraction methods, a series of RF-MOSFETs and planar on-chip spiral inductors with different geometries manufactured by employing standard RF CMOS processes were considered. Excellent agreement between the measured and the simulated results validate the compact models and modelling technologies developed in this work.
Upgrade of the JET Gamma‐Ray Cameras

The JET gamma‐ray camera diagnostics have already provided valuable information on the gamma‐ray imaging of fast ion in JET plasmas /1,2/. The applicability of gamma‐ray imaging to high performance deuterium and deuterium‐tritium JET discharges is strongly dependent on the fulfilment of rather strict requirements for the characterisation of the neutron and gamma‐ray radiation fields. These requirements have to be satisfied within very stringent boundary conditions for the design, such as the requirement of minimum impact on the co‐existing neutron camera diagnostics. The JET Gamma‐Ray Cameras (GRC) upgrade project deals with these issues with particular emphasis on the design of appropriate neutron/gamma‐ray filters (“neutron attenuators”). Several design versions have been developed and evaluated for the JET GRC neutron attenuators at the conceptual design level. The main design parameter was the neutron attenuation factor. The two design solutions, that have been finally chosen and developed at the level of scheme design, consist of: a) one quasi‐crescent shaped neutron attenuator (for the horizontal camera) and b) two quasi‐trapezoid shaped neutron attenuators (for the vertical one). The second design solution has different attenuation lengths: a short version, to be used together with the horizontal attenuator for deuterium discharges, and a long version to be used for high performance deuterium and DT discharges. Various neutron‐attenuating materials have been considered (lithium hydride with natural isotopic composition and 6Li enriched, light and heavy water, polyethylene). Pure light water was finally chosen as the attenuating material for the JET gamma‐ray cameras. The neutron attenuators will be steered in and out of the detector line‐of‐sight by means of an electro‐pneumatic steering and control system. The MCNP code was used for neutron and gamma ray transport in order to evaluate the effect of the neutron attenuators on the neutron field of the JET GRC. The modelling was dedicated to the estimation of neutron and (plasma‐emitted) gamma‐ray attenuation, neutron‐induced gamma‐ray background and the neutron in‐scattering impact on the neutron detectors due to the attenuator in the parking location. A numerical study of the gamma‐ray detector (CsI(Tl)) was done by means of the IST Monte Carlo code. It provided preliminary results on the detector efficiency and response function.
Preservice Teachers’ Motivations for the Accounting Teaching Profession: Fit-Choice Findings from a Selected Public Universities in Ghana

Teacher motivation influences teachers’ actions in the classroom and student achievement. Grounded in the FIT-Choice model, the study investigated the perception of preservice teachers about accounting teaching profession. Again, the study examined the motivational factors that attract preservice teachers to the accounting teaching profession. Descriptive cross-sectional survey design was used for the study. The population comprised all final year Bachelor of Education accounting students of University of Cape Coast and University of Education, Winneba (i.e 2018/19 academic year). Proportionate stratified sampling technique was utilised to engage 226 preservice teachers (students) in a survey. FIT-Choice scale developed by Watt and Richardson (2007) was adapted and used. Data to answer research question 1 and 2 were analysed using mean and standard deviation. Findings revealed that preservice teachers have a positive perception about the accounting teaching profession. Again, findings showed that preservice teachers were attracted to the accounting teaching profession predominantly by social utility value and personal utility values. The study recommends that academic advisors, counsellors and faculty must continue to strengthen career guidance and counselling among students (i.e., preservice teachers) to sustain the positive view that preservice teachers have about the accounting teaching profession.
Development of a Prone Bridge Test as a Measurement of Abdominal Stability in Healthy Adults

DEVELOPMENT OF A PRONE BRIDGE TEST AS A MEASUREMENT OF ABDOMINAL STABILITY IN HEALTHY ADULTS Joel Reece Department of Exercise Sciences Master of Science This study sought to develop an interval prone bridge fitness test to assess core stabilization in healthy adults (ages 18–39 years). Participants performed a prone bridge maneuver in alternating 15-sec work and 5-sec rest intervals with participants’ RPE scores (0–10) recorded at the end of each work interval. The RPE score reported after 95 sec (RPE-95) was used to predict total interval prone bridge endurance time along with participants’ self-reported level of physical activity (PA; sedentary = 0, low active = 1, active = 2, very active = 3). Multiple linear regression was employed to generate the following prediction equation (R = .86, SEE = 32.98 sec): Total time (sec) = 300.0 – (23.4 x RPE-95) + (17.7 x PA). Each predictor variable was statistically significant (RPE-95, p < .0001; PA, p = 0.006) and cross validation procedures using PRESS (predicted residual sum of squares) statistics revealed minimal shrinkage (Rp = .85 and SEEp = 32.89 sec). The mean and standard deviation (±SD) for the total duration of the interval prone bridge test and the RPE-95 data were 179.9 ± 65.2 sec and 6.3 ± 2.2, respectively. To assess test-retest reliability, a second test was completed about 48 hours after the first. The reliability study (n = 45) yielded an acceptable test-retest intraclass reliability coefficient (ICC = .95, SEM = 12.7 sec) when comparing total interval prone bridge endurance times across days. In summary, this interval prone bridge fitness test, and accompanying regression model, yields a relatively accurate estimate of total interval prone bridge test time in healthy men and women, using both RPE-95 and PA data.
Risk Factors for Cardiovascular Diseases in Aircrew

The relation of atherosclerotic cardiovascular disease (ASCVD) to not only traditional but also new and emergent risk factors has been assessed in aircrew. Total flight hours (TFH), high altitude and weightlessness exposure have been accounted among traditional risk factors for CVD among the aircrew. The risk factors do not perform in loneliness. To predict the 10 years global CV risk, several scores are being applied either based on traditional CVD risk factors only or also including new and emergent risk factors. To prevent aircrew from developing CVD, one should focus on the control of behavioral and metabolic risks as well as the polymorphe treatment of high CV risk individuals.
Aeromonas Hydrophila Infection Activates Death Receptor Apoptosis Pathway in the RBCs of Grass Carp (Ctenopharyngodon idellus)

Background: Fish blood contains RBCs (Red blood cells) as the major cells. Unlike the absence of nucleus in mammalian RBC, fish RBC contains a nucleus. Previous researches have indicated that fish RBCs have a significant function in immune responses. However, the mechanism underlying the immune responses against bacterial infection of teleost RBCs remains enigmatic. To decipher the mechanisms, after the infection of A. hydrophila, transcriptomic profiling of grass carp RBCs was analyzed. Results: Outcomes demonstrated that there were 2144 altogether DEGs (Differently Expressed Genes) between the A. hydrophila non-disease groups, which includes 817 up-regulated and 1327 down-regulated DEGs. Differently Expressed Genes were allocated to 45 GO terms, including 20 natural procedure terms, 14 cell related element, and 11 terms related to molecular functions. Likewise, the expression levels of cytokines by Quantitative Reverse Transcription Polymerase Chain Reaction showed that they (e.g. CCL4, CCL11, CCL20, IL-4, IL-12, and IFNα) were significantly increased after A. hydrophila infection, which was identical to the expression patterns of transcriptomic data. The infection could cause the apoptosis of RBCs which was confirmed by annexin V/PI assay. To further elucidate the apoptosis pathway, the expression levels of genes by mRNA included in cellular apoptosis were monitored. The outcomes indicated that the expressions of mRNA of p53, Fas, Leucine-rich repeats, death domain-containing (LRDD) and caspase 8 were all significantly increased, respectively. Conclusions: Our results support the notion that A. hydrophila infection could activate Fas-related death receptor apoptosis pathway in grass carp RBCs, which will reveal another insight on the mechanisms underlying the antibacterial immunity of teleost fish RBCs.
Polyphase Boost Converter with Digital Control

Abstract Boost d.c.-d.c. converters have very good source interface properties. The input inductor makes the source current smooth and hence these converters provide very good EMI performance. On account of this good property, the boost converter is also the preferred converter for off-line UPF rectifiers. One of the issues of concern in these converters is the large size of the storage capacitor on the dc link. The boost converter suffers from the disadvantage of discontinuous current injected to the load. The size of the capacitor is large. Further, the ripple current in the capacitor is as much as the load current; hence the ESR specification of the tank capacitor is demanding. This paper presents the polyphase boost converter, which overcomes the problem of high ripple current in the tank capacitor, which has not been discussed earlier. Comparison between the specifications of single stage and multistage is thoroughly examined. Digital control is more convenient for such a topology on account of the requirement of synchronization, phase shifted operation and current balancing. The control method is simpler and faster than its original form [10]. It does not depend on the previous duty ratio and it has been tested on four boost converters in parallel. Each is a 35W unit switched at 200 kHz. Experimental results in digital control, synchronization operation and current sharing are presented. The control method is implemented using a TI’s general purpose Digital Signal Processor eZdspF2812. This control scheme is applicable for PFC rectifiers as well.
3D Time-of-Flight Camera for Surveying Remote Cavities Mined with a Jet Boring System

The Cigar Lake ore body is a high-grade uranium deposit situated within water-saturated sandstone. In order to extract the uranium ore remotely, ensuring minimal radiation dose to workers, and also to access the ore from stable ground, the Jet Boring System (JBS) was developed. This method of mining involves drilling a pilot hole up through a frozen ore body and utilizing a high-powered water jet to mine out cavities. During the mining process an ultrasonic sensor will be used to provide feedback to the operator, who is located beneath the ore body, as to the dimensions of the cavity. However, more precise data is required to determine final shape, volume, and location of the cavity for mine planning purposes. Selecting a device that will provide sufficient range data in the challenging environment will be vital to optimizing the mining process. Major issues include fog build up and flying debris during mining, and an environment that is wet, dark, and cold. A test cavity has been designed and constructed at the Saskatchewan Research Council (SRC) so that a study comparing three different technologies, as prospective candidates for the survey system, can be conducted. The devices being evaluated include a Senix ultrasonic sensor, an MDL Cavity Auto-Scanning Laser System (C-ALS), and a MESA Time of Flight (ToF) camera. The ultrasonic sensor is known to provide range data in foggy conditions but has low accuracy. The C-ALS has been developed for surveying remote cavities but is expensive and does not provide reliable data in fog. The ToF camera provides a high volume of data in a short time period, with potential to provide accurate information in extreme conditions, but has not been tested in a mine cavity application. Iterative closest point (ICP) registration is applied in an attempt to create a 3D point cloud from the scan data and to also compute rotation and translation of the ToF camera. This paper presents an overview of the challenges involved in conducting a survey within a JBS mined cavity, the analysis used to determine the suitability of each device, and the data collected from the test cavity.
Not an academic type: what do communication designers know about research?

AbstractCommunication designers, like all designers, operate in the generative yet problematic territory that exists between science and art. Their work is technical and instrumental, yet simultaneously imaginative, intuitive and creative. This is an activity of becoming through the poetics of the material. The relationship between the communication designer and client creates an intersubjective space in which new knowledge is both enabled through and accessed in materialised propositional artefacts. This knowledge is both experiential and tacit, formed in the interstices between designer and the other.How can the activity of communication design, and the knowledge it produces, find a place in academic research? How might research be undertaken, not only about design but also through design? Some aspects of design can be adequately analysed, described and optimised using the methods of scientific research. This paper argues however, that the aims of this particular research project—to better understand th.
AUTOMATED PEDESTRIAN DETECTION USED IN CONJUNCTION WITH STANDARD PEDESTRIAN PUSH BUTTONS AT SIGNALIZED INTERSECTIONS

Automated pedestrian detection systems provide the means to detect the presence of pedestrians as they approach the curb prior to crossing the street and then use that information to "call" the WALK signal without any action required on the part of the pedestrian. The objective of this study was to evaluate whether automated pedestrian detection systems, when used in conjunction with the push button, would result in fewer overall pedestrian/vehicle conflicts and fewer inappropriate crossings, such as beginning to cross during a DON'T WALK signal. Before and after video data were collected at intersection locations in Los Angeles, California (infrared--IR--and microwave), Phoenix, Arizona (microwave), and Rochester, New York (microwave). The results indicated that the use of automated detection devices in conjunction with the standard pedestrian pushbutton resulted in a significant reduction in vehicle-pedestrian conflicts as well as a reduction in the number of pedestrians beginning to cross during the DON'T WALK phase. Differences between microwave-based and IR-based devices were not significant. Detailed field testing of the microwave equipment in Phoenix revealed that fine tuning of the detection zone is still needed to reduce some false calls and missed calls.
Characterizing the Effects of Simulated Injury on the Structure and Function of the Glenohumeral Capsule.

Anterior glenohumeral dislocation is a significant clinical problem, which can result in the glenohumeral capsule being loaded beyond its elastic limit (permanently deformed). Diagnosing and treating this pathology is difficult as currently no reliable method for determining the location and extent of capsular damage exists. Consequently, following repair ~20% of patients experience recurrent dislocations and ~50% are at risk for developing osteoarthritis. Existing knowledge of the structure and function of the capsule following permanent deformation is minimal and may be the root cause behind these issues. A greater awareness of how injury affects this structure will enable specific at-risk locations to be targeted during repair. Additionally, validated finite element models of the glenohumeral joint may be able to improve patient treatments; but require adequate constitutive models to describe normal and injured capsule behavior. Therefore, the goal of this work was to evaluate the effect of anterior dislocation on the structure and function of the capsule from three levels: microstructure, tissue, and joint; and to suggest improvements to a constitutive model for the capsule. At the microstructural level, collagen fiber alignment increased with uniaxial extension and was able to predict the location of tissue failure. Following simulated injury of tissue samples from the capsule, the stiffness and modulus of stress-stretch curves increased by 47% and 128%, respectively, but changes were not detectable in the parameters of a phenomenological constitutive model. Anterior dislocation permanently deformed the capsule and resulted in increased anterior translations and glenohumeral contact forces of 18-48% and 41-148% at three joint positions. Finally, a structural constitutive model was found to better predict the complex capsule behavior than the phenomenological model; but accounting for non-affine fiber kinematics may further improve the accuracy of computational models. This work suggests that surgical repair procedures targeting the anterior capsule based on increased anterior translation during pre-operative physical exams are not addressing the appropriate region of the capsule; rather the posterior axillary pouch suffers the most damage following anterior dislocation. Therefore, current physical examinations may not be capable of identifying specific locations of tissue damage and future research to standardize physical exams is warranted.
Proceedings of the Eighteenth Annual Biochemical Engineering Symposium

Corn gluten meal was hydrolyzed using Alcalase 2.41, an alkaline protease. The effects of enzyme concentration and gluten size reduction on the hydrolysis were studied. Extent of reaction was expressed both in terms of the degree of hydrolysis (using the pH stat technique) and the concentration of soluble protein. Kinetic models were compared to the experimental results by minimizing the residual sum of squares between the ~odel and the results. The models describe the time dependent behavior of three protein/peptide pools-insoluble protein, TCA-insoluble proteins and TCA-soluble peptides.
Initial Imperfection Characteristics of Mono-Symmetric LiteSteel Beams for Numerical Studies

The aim of the present study is to investigate the initial imperfection characteristics of the new mono-symmetric LiteSteel beams (LSB) and their effects on the moment capacity. A unique manufacturing process of simultaneous cold-rolling and electric r esistance welding process is used in the manufactur ing of LSBs that can lead to unique initial imperfections i n the form of initial geometric distortions and res idual stresses. Such imperfection characteristics are unl ikely to be present in conventional steel beam sect ions. In this study, the imperfections in LSBs were measured and their effects on the moment capacities were investigated using finite element analyses. It also included a sensitivity study of geometric imperfec tions and residual stresses on LSB moment capacities. This pa per presents the details of this study, the results , and useful recommendations for numerical modelling, design and manufacturing of LSBs.
On gazers’ encounters with visual art: ekphrasis, readers, ‘iconotexts’1

This chapter defines ekphrasis concisely as ‘the verbal representation of real or fictive configurations composed in a non-kinetic visual medium’. It rejects narrower definitions that exclude texts on non-representational visual configurations, including architecture, or restrict the discourse to literary texts representing works of art. But with its emphasis on the text the concise definition unduly reinforces the consideration of ekphrasis as a form of ‘intermedial transposition’ in contemporary discourse on intermedial relations. An ekphrastic text should be primarily approached as the record of a viewer’s interpretive encounter with a non-kinetic visual configuration, which may not actually contain anything that has been ‘transposed’ from the image. This viewer may be the persona of a poem, a figure in a prose narrative, or an art critic. It is the reader’s task to construct these viewers in the interpretation of any ekphrastic text. But the role of the reader has not received much attention. This includes the question of the immediate mental reception of ekphrastic texts. The critical construct of ‘iconotexts’, suggesting that such verbal texts spontaneously trigger a mental visual image for the informed reader, is problematic, and even in a more general sense the term may be of limited critical use.
Tourist Satisfaction in the Malaysia Tourism Industry: Relationship between Service Innovation and Destination Image

Malaysia has often been recognized by both local and international tourists as a premier visiting destination. Perception of a tourist destination, thus, has an important bearing on eventual tourist satisfaction. This study examines various aspects of service innovation that influence destination image in the Malaysian tourism industry. Data collected through self-administered questionnaires from 550 tourists using a convenience sampling approach were subjected to a reliability test, followed by multiple linear regression analysis to assess the proposed research hypotheses. The findings show that four variables of service innovation (product innovation, process innovation, organisational innovation and marketing innovation) were significantly and positively associated with destination image that, in turn, reflected tourist satisfaction. Nevertheless, the nationality of the tourist had a mediating effect on the relationship between destination image and tourist satisfaction. Tourism practitioners could benefit from these findings when the principles they espouse are applied to tourism management. At the same time, academic researchers would derive a better understanding of the factors that enhance destination image and, ultimately, tourist satisfaction. (i.e. individual relationship, accommodative of a A study by and Devesa-Fernández highlighted motivations between both international and domestic tourists as a crucial factor that guides organisational endeavours in cultivating
