Motion prediction and dynamic stability analysis of human walking : the effect of leg property

The objective of this thesis is to develop and validate a computational framework based on mathematical models for the motion prediction and dynamic stability quantification of human walking, which can differentiate the dynamic stability of human walking with different mechanical properties of the leg.Firstly, a large measurement database of human walking motion was created. It contains walking measurement data of 8 subjects on 3 self-selected walking speeds, which 10 trials were recorded at each walking speed. The motion of whole-body centre of mass and the leg were calculated from the kinetic-kinematic measurement data. The fundamentals of leg property have been presented, and the parameters of leg property were extracted from the measurement data of human walking where the effects of walking speed and condition of foot-ground contact were investigated. Three different leg property definitions comprising linear axial elastic leg property, nonlinear axial elastic leg property and linear axial-tangential elastic leg property were used to extracted leg property parameters. The concept of posture-dependent leg property has been proposed, and the leg property parameters were extracted from the measurement data of human walking motion where the effects of walking speed and condition of foot-ground contact were also investigated. The compliant leg model with axial elastic property (CAE) was used for the dynamic stability analysis of human walking with linear and nonlinear axial elastic leg property. The compliant leg model with axial and tangential elastic property (CATE) was used for that with linear axial-tangential elastic leg property. The posture - dependent elastic leg model (PDE) was used for that with posture-dependent leg property. It was found that, with linear axial elastic leg property, the global stability of human walking improves with the bigger touchdown contact angle. The average leg property obtained from the measurement data of all participants allows the maximum global stability of human walking. With nonlinear axial elastic leg property, the global stability decreases with the stronger nonlinearity of leg stiffness. The incorporation of the tangential elasticity improves the global stability and shifts the stable walking velocity close to that of human walking at self-selected low speed (1.1-1.25 m/s). By the PDE model, the human walking motions were better predicted than by the CATE model. The effective range of walking prediction was enlarged to 1.12 ? 1.8 m/s. However, represented by PDE model, only 1-2 walking steps can be achieved. In addition, the profiles of mechanical energies represented by the PDE model are different from that of the orbital stable walking represented by CATE model. Finally, the minimal requirements of the human walking measurements and the flexibility of simple walking models with deliberate leg property definitions allow the computational framework to be applicable in the dynamic stability analysis of the walking motion with a wide variety of mechanical property of the leg.
Moleculare detection of Bartonella in ixodid ticks and plateau pika (Ochotona curzoniae) in Shiqu county, China

Background Bartonella bacteria have been associated with an increasingly wide range of human and animal diseases and were also recognized to be globally dispersed as emergent pathogens. Ticks and small rodents are known vectors of human and animal bartonellosis and play important roles in maintenance and circulation of bartonellae in nature. In China, Shiqu county is located on the eastern Qinghai-Tibetan plateau and about 26 thousands square kilometers with an average altitude of above 4,200 meters and vast area of pastureland. In present study, the occurrence of Bartonella spp. in ticks and plateau pika was firstly investigated in Shiqu county.Results A total of 818 ticks ( Dermacentor everestianus , 79.0%, 646/818; Haemphysalis qinghaiensis , 21.0%, 172/818), were collected in 4 villages in Shiqu county. Only Bartonella melophagi was detected in tick samples with a total prevalence of 30.1% (246/818). Significant difference was observed (P<0.05) between D.everestianus (17.0%) and H.qinghaiensis (79.1%). The infection rates of Bartonella spp. in ticks from Arizha, Maga, Derongma and Changxgma villages were 4.8%, 76.8%, 12.5% and 18.0%, respectively. Compared with other villages, the infection rate of Bartonella spp. in Maga was higher (P<0.01). As for plateau pika, total infection rate of Bartonella spp was 24.1%, with 20.8% (15/72), 30.9% (25/81), 13.8% (9/65) and 29.4% (20/68) in Arizha, Maga, Derongma and Changxgma, respectively. Totally, B. queenslandensis , B.grahamii and two unvalidated Bartonella species were detected. No significant difference in infection rates was observed (P>0.05) between theses study sites. Conclusion At present, only D.everestianus and H.qinghaiensis were found in Shiqu county with high infection of Bartonella spp. in theses ticks and plateau pika. The threats to public health by these Bartonella species should be monitored.
Hot Stone Technology at Bucklers Park, Crowthorne, Berkshire: The Use and Re-use of a Persistent Place During the Bronze and Iron Ages

Archaeological investigations at Bucklers Park in Crowthorne have revealed a window onto a significant later prehistoric place, which was used and revisited over 1700 years between the Early Bronze Age and later Iron Age (c. 1800–100 bc). Activity on site was based around the heating of water using fire-heated flint, producing three mounds of fire-cracked flint and burnt organic material. These ‘burnt mounds’ are known across later prehistoric Britain and Ireland, but the ways they may have been formed are uncertain, and they are arguably under-discussed in southern Britain. Whilst water was initially drawn from a stream, a series of wells were established at the site between the Middle Bronze Age and Early Iron Age, one of which contained a well-preserved log ladder. These wells were revisited and recut over long periods of time and during the Middle Iron Age the site’s function shifted dramatically when a roundhouse was constructed. The long-term use of the site, its excellent organic preservation, dating, and its location in a remote area on the Bagshot Heath, make it significant. This paper summarises the findings from the excavations, discussing the formation of the site in the context of wider research on later prehistoric burnt mounds.
Integrating life cycle analysis and the ecological footprint calculator to foster sustainable behaviors

Many tools have been developed to assess global, national or regional sustainable development policies. However, as governments develop sustainable policies, individuals must also feel empowered to affect their personal impact on the planet. This thesis integrates three sustainability concepts that lend themselves to individual sustainability: The natural step, life cycle assessment, and the ecological footprint. TNS serves to provide the meaning and substance toward sustainable development. LCA helps provide the framework for assessing sustainability. The EF calculator determines the driving components and measures the qualitative decisions made through TNS and LCA. From the analysis of the household footprint calculator a simplified footprint calculator was developed to assist individuals and communities in setting benchmarks and goals as they move away from over-consumption and towards a sustainable lifestyle.
Analysis and modeling of substrate noise coupling for NMOS transistors in heavily doped substrates

approved: Kartikeya Mayaram Tern S. Fiez This thesis examines substrate noise coupling for NMOS transistors in heavily doped substrates. The study begins with the analysis of an NMOS transistor switching noise in a digital inverter at the device level. A resistive substrate network for the NMOS transistor is proposed and verified. Coupling between N+P+ contacts is compared both qualitatively and quantitatively with simulations. The difference between the N-P and P-P coupling is in the cross-coupling parameter. A new N-P model, which requires only five parameters, is proposed by taking advantage of an exsiting P-P model combined with the concept of a virtual separation. This model has been validated up to 2GHz with Medici simulations. The virtual separation concept has been validated with 2D/3D simulations and measurements from test structures fabricated in a 0.35iim TSMC CMOS heavily doped process. This model is useful when transistor switching noise is the dominant source of substrate noise. Applications of the new N-P model are demonstrated with circuit simulations.

Assessing the Quality Improvement Process of Hypertensive/Diabetic Patients through Medical Outpatient Compliance tracking in Chow Hospital, Warri, Delta State, Nigeria – A Three-Year Retrospective Study From 2015-2017

Medical Outpatient Clinic in CHOW Hospital, Warri comprises all the patients seen and managed by the Physician. These include patients with Diabetes Mellitus, Hypertension, Retroviral illness, general medical conditions requiring non-surgical management and other heart-related conditions. However, this Medical OutPatient (MOP) Survey is carried out mainly on Hypertensive/ Diabetic patients. The survey looks into the number of clients scheduled to see the physician per month, the actual number that attended the MOP clinic and those that were absent. It also captures the number of defaulters that responded after a call-out and those who remained chronically non-compliant with the MOP clinic schedule even after several reminders. In this survey, the malefemale gender ratio is also taken into consideration. It is also of note that extra MOP patients who were not originally scheduled for the months but utilized the MOP clinic are also captured in this survey. Background of the study
Control Structure and Tuning Method Design for suppressing Disturbances in a multi-phase Separator

In this project report the control structure for a three phase separator for a oil production unit is examined. The purpose is to analyse the control structure, and make the suggestion for how a control structure based on single loop control, can be designed to reject large disturbance occurring in the system. The second goal is to make a tuning method based on the plant properties to prevent process shutdown, that keeps the process running smooth. The assignment text states that the following tools can be used to develop the control structure: feed forward control, gain scheduling, first and second order filters, PI- and PID-controllers. A process model containing all process variables is derived in the report. For verification purposes and development of control structure and tuning, the model is implemented in MATLAB and Simulink where simulations are done. The model is normalised such that the control structure is tested for the general case. Plant verification model is based on dimensions from a real plant, but process parameters are changed for comparing with other plants. Tools like gain scheduler, anti-windup, derivative filter and low pass filter are derived and designed for the purpose. The report shows which parameters that limit the process performance and which techniques that should be used to reduce their impact to the system. There is also made analysis for how control loops and the controller can regard the limitations. An important part of this is the development of a signal filter to reduce measurement noise in the system. As a basis for controller tuning SIMC is used. The system is analysed to find a method adapted for separator tuning. The customised method is tested for different plants and compared to SIMC to verify the abilities to control the plant. Analyses of the system, is done for a linear system, even though the system is nonlinear. To be able to use linear system techniques, analysis is done for the system linearised around setpoint and chosen points within the working area. The result of the report, is a suggestion for how single loop control structure, and tuning can be performed for a separator based on the plant properties.
Urbanization-induced land and aerosol impacts on sea-breeze circulation and convective precipitation

Abstract. Changes in land cover and aerosols resulting from urbanization may impact convective clouds and precipitation. Here we investigate how Houston urbanization can modify sea-breeze-induced convective cloud and precipitation through the urban land effect and anthropogenic aerosol effect. The simulations are carried out with the Chemistry version of the Weather Research and Forecasting model (WRF-Chem), which is coupled with spectral-bin microphysics (SBM) and the multilayer urban model with a building energy model (BEM-BEP). We find that Houston urbanization (the joint effect of both urban land and anthropogenic aerosols) notably enhances storm intensity (by ∼ 75 % in maximum vertical velocity) and precipitation intensity (up to 45 %), with the anthropogenic aerosol effect more significant than the urban land effect. Urban land effect modifies convective evolution: speed up the transition from the warm cloud to mixed-phase cloud, thus initiating surface rain earlier but slowing down the convective cell dissipation, all of which result from urban heating-induced stronger sea-breeze circulation. The anthropogenic aerosol effect becomes evident after the cloud evolves into the mixed-phase cloud, accelerating the development of storm from the mixed-phase cloud to deep cloud by ∼ 40 min. Through aerosol–cloud interaction (ACI), aerosols boost convective intensity and precipitation mainly by activating numerous ultrafine particles at the mixed-phase and deep cloud stages. This work shows the importance of considering both the urban land and anthropogenic aerosol effects for understanding urbanization effects on convective clouds and precipitation.
TECHNOLOGY ENHANCED VISIT TO MUSEUMS. A CASE STUDY: "KEYS TO ROME"

What a boring experience! ” This could be a teenager comment after a school trip to a museum. In fact, the general idea about museums is that they are locations merely devoted to the exposition of artifacts and showcases, places considered as boring and uncommunicative, far away from our everyday life. In this paper we are going to present a case study based on our experience related to the “Keys to Rome” exhibition, the final event of V-Must.net project (Virtual Museums Transnational Network), where we focused our attention on two main aspects with the purpose of demonstrating that technology can help in changing the common idea about museums. First, we analyzed the users’ ability in interacting with the technology available in the exhibit to measure the real level of user usability. Second, we evaluated the pedagogical potentiality of these technological applications for further researches with schools. “Keys to Rome” is an exhibition, unique in its genre, that runs in parallel in four different connected locations: Alexandria of Egypt, at the Bibliotheca Alexandrina; Amsterdam, at the Allard Pierson Museum; Sarajevo, at the Archaeological Museum, and Rome, at the Imperial Fora Museum. In this context technology plays a very important role: with augmented reality applications, natural interactions, serious games, virtual reconstructions, holographic displays, it contributes to create an innovative environment that helps the users in understanding, enhancing and developing their level of immersion and finally the experience as a whole. Therefore, thanks to technology visitors do not step into a regular museum but they can travel through time and space in a virtual - and virtuous - visit of the Past.
Navigation, guidance, and control systems for V/STOL aircraft.

The development of digital autopilots and integrated avionics systems, applicable to many classes of vehicles and missions, was undertaken by Sperry Flight Systems in the mid-sixties. The first application of the system was planned for automatic flight control in the U.S. supersonic transport; the termination of that program, however, thwarted any flight experience. The second application, which has additional navigation and energy management functions, is an airborne simulator of the space shuttle vehicle. The latter system underwent a series of successful flight tests in a CV-990 aircraft under contract with NASA. The third application, which has new electronic displays, air data computation, and time-constrained guidance (i.e., specified position and altitude at a specified time), is in the DOT/NASA STOLAND test program. The STOLAND system is described specifically in this paper.
Beginning Course Surveys: Bridges for Knowing and Bridges for Being.

The use of a participant survey, administered at the outset of an online course, can provide information useful in the management of the learning environment and in its subsequent redesign. Such information can clarify participants’ prior experience, expectations, and demographics. But the very act of enquiring about the learner also signals the instructor’s social presence, relational interest, and desire to enter into an authentic dialogue. This study examines the use of participant surveys in online management courses. The first section discusses the informational bridges that this instrument provides. The second section considers survey responses to open-ended questions dealing with student sentiments. This analysis suggests that the survey plays a valuable part in accentuating social presence and in initiating relational bridges with participants.
The relationship between skipping breakfast and depression among workers with a focus on psychosocial factors

Objective Previous studies have indicated that skipping breakfast is not only detrimental to physical health, but is also associated with depression. Myriad psychosocial factors are associated with both skipping breakfast and depression. However, previous research failed to account for these potential psychosocial factors. The aims of this study were to (a) explore the factors associated with breakfast consumption, and (b) investigate the association between the frequency of breakfast consumption and depression, adjusted for various forms of psychosocial confounders by analyzing previously collected data concerning Japanese workers. Result Participants were 575 employee across three Japanese worksites. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression Scale (CESD). Frequency of breakfast consumption was categorized into 6 levels. Multi-regression analysis suggested that skipping breakfast was associated with high trait aggression, living alone, and low levels of physical exercise. Logistic regression suggested that skipping breakfast was associated with depression, even after adjusting for potential psychosocial factors including trait aggression, resilience, physical exercise, consumption of fish and fried food, social support, and life events cannot be ruled out.
Robust geometric methods for surface modeling and manufacturing

We investigate methods to aid in the process of going from a conceptual shape of a part to its physical realization. We present contributions to the “design for manufacture” problem in two major areas: surface model representation and process planning for layered manufacturing. In surface modeling, the focus is on subdivision surfaces and the analysis of their continuity behavior. We present a new algorithm for the exact evaluation of piecewise smooth Loop and Catmull-Clark surfaces near user-defined sharp features. This algorithm aids in the geometric process planning of subdivision surfaces for manufacturing. On the process planning side, we have developed an approach to layered manufacturing that produces parts with thin, dense walls filled with a loose web-like interior to reduce material usage and accelerate build times. The key algorithm in this process generates a conservative offset of a polyhedral surface by generating a stack of 2D slice contours, calculating individual offset contours, and forming appropriate Boolean combinations of these contours. We describe a numerically robust algorithm for constructing the generalized Voronoi diagram of polygonal slice contours which is then used to generate clean offset contours for each slice, which are combined between layers to create the conservative 3D offset surface.
Clinical Training with Undocumented Latinx Immigrant Minors: Case Examples and Reflections using the Multicultural Developmental Supervisory Model (MDSM) as a Framework.

As of 2017, the number of international immigrants worldwide increased from 220 million to 248 million, and will continue to rise [16]. Growing diversity worldwide requires a stronger emphasis on multicultural competency among mental health professionals. Learning multicultural competency skills is a career-long commitment that begins in practicum training and is modeled and reinforced through supervision. The Multicultural Developmental Supervisory Model (MDSM) is an evidence-based model that focuses on supervisory dyads and multicultural competence [12]. Using the MDSM [12] as a guide reflective of our training, four graduate supervisees share their supervision experiences in learning to conduct clinical interviews in Spanish with undocumented Latinx immigrant minors in government custody in the United States, a rising population with unique clinical considerations. Our supervisor includes her experience in training and fortifying beginning mental health professionals’ skills in conducting these evaluations. In this contribution, we illustrate our trajectory from different training developmental stages, including the process of conceptualizing clinical cases, and transitioning languages in conducting clinical interviews, as well as considering our own cultural identities in clinical work. While our experience focuses on bicultural and bilingual training in the U.S., this aspect of clinical training is growing increasingly relevant around the world, especially in Europe where 54% of the population is multilingual [10]. Although we used the MDSM model as a helpful framework in guiding our multicultural development, empirical research is needed to examine the utility of this model.
