From Radio Channel Modeling to a System Level Perspective in Body-Centric Communications

Body-centric communications are emerging as a new paradigm in the panorama of personal communications. Being concerned with human behaviour, they are suitable for a wide variety of applications. The advances in the miniaturization of portable devices to be placed on or around the body, foster the diffusion of these systems, where the human body is the key element defining communication characteristics. This thesis investigates the human impact on body-centric communications under its distinctive aspects. First of all, the unique propagation environment defined by the body is described through a scenario-based channel modeling approach, according to the communication scenario considered, i.e., on- or on- to off-body. The novelty introduced pertains to the description of radio channel features accounting for multiple sources of variability at the same time. Secondly, the importance of a proper channel characterisation is shown integrating the on-body channel model in a system level simulator, allowing a more realistic comparison of different Physical and Medium Access Control layer solutions. Finally, the structure of a comprehensive simulation framework for system performance evaluation is proposed. It aims at merging in one tool, mobility and social features typical of the human being, together with the propagation aspects, in a scenario where multiple users interact sharing space and resources.
Comparative studies on scale-up methods of single-use bioreactors.

Comparative Studies on Scale‐Up Methods in Single‐Use Bioreactors by Emily Stoker, Master of Science Utah State University, 2011 Major Professor: Dr. Timothy Taylor Department: Biological Engineering This study was performed to increase knowledge of oxygen mass transfer (kLa) and mixing times in the scale‐up of disposable bioreactors. Results of oxygen mass transfer studies showed kLa to increase with increasing agitation and aeration rates. By maintaining a scale‐up constant including gassed power to volume or shear, an almost constant kLa was achieved during scale‐up from 50 to 2000 L. Using the scale‐up constant Pg/V resulted in statistically higher kLa values at greater reactor volumes. Mixing times were revealed to be significantly affected by agitation, but not by the aeration rates tested. No pattern was recognized in the mixing time data over an increase in volume. Commonly used methods for predicting kLa upon scale‐up were compared to experimental data. New coefficients were determined in order to fit the historic models to the parameters of this study, namely the unique geometry and low agitation and aeration rates used in the single‐use systems. Each of the resulting four models was found to have average error rates from 16‐23%. Although the error rates are not statistically different, the Moresi and Patete model was determined to be most conceptually accurate when comparing the theoretical concepts behind the models. The Moresi and Patete model found kLa to be more

THE ROLE OF CENTRAL AND PERIPHERAL OPTIC FLOW IN THE CONTROL OF UPRIGHT POSTURE

Several studies have examined the influence of optic flow presented in the central and peripheral fields of view on postural sway, but they have yielded diverging results. Early reports suggested that movement in the periphery was associated with increased sway. Later studies have argued that central movement is equally important. The primary objective of this set of experiments was to further investigate the influence of central and peripheral optic flow on postural equilibrium. The postural sway of 20 healthy subjects (ages 21-30 years) was measured while they viewed moving visual stimuli in a computer-generated immersive environment encompassing their entire horizontal field-of-view (FOV). Two main studies were conducted. In the first, optic flow was presented at different FOVs, but the motion contained only one frequency component during each trial. In the second, the central and peripheral regions of the visual stimulus moved simultaneously but at different frequencies.In the first experiment, the location of the optic flow stimulus significantly affected the number and size of significant postural responses. There were twice as many significant postural responses to the peripheral optic flow condition compared to the central optic flow. In addition, the magnitude of the response to the peripheral optic flow was 6.5 times greater than the response to the central flow. The number and magnitude of significant responses were also greater for higher-frequency stimuli, after accounting for quiet-stance sway components. In the second experiment, there were 3.5 times as many significant postural responses to the peripheral optic flow stimulus as there were to the central optic flow. Likewise, the amount of sway was greater in response to the peripheral stimulus.The results of both experiments suggest that the postural system is more sensitive to anterior-posterior optic flow in the peripheral FOV, regardless of stimulus frequency. These findings have implications for the use of virtual environments, showing that head-mounted displays with a limited central FOV do not provide the visual information most important for postural control. Furthermore, the results suggest that rehabilitation therapists should incorporate peripheral movement cues in treatment to enhance balance retraining.
Performance in Professional Courses as Predictor of Psychometrician Licensure Examination (PMLE) of Psychology Graduates From a Private University in the Philippines

This study aimed at determining the performance of BA/BS Psychology graduates in professional courses as predictor of Psychometrician licensure examination. This descriptive-correlational study involved 104 psychology graduates from academic year 2015-2018 of the University of Perpetual Help System Laguna, Binan Campus. Findings showed that majority of the respondents had a satisfactory grade in professional courses. Nearly half of them passed the licensure examination. A significant relationship was noted between the respondents’ academic performance in professional courses along Psychological assessment (p=0.005), Abnormal psychology (p=0.000) and Industrial psychology (p=0.000) and their Psychometrician licensure examination. Among the professional courses included in the licensure examination Abnormal psychology was found to be a good predictor of their Psychometrician licensure examination which may be attributed to teacher’s competence in teaching the course, effective instruction and quality of education that reflects the school efficiency.
Cultural influences on the implementation of production management tools: a literature review

Engineers and many other professionals usually solve production issues by applying pre-existing polices, like Total Quality management, Six Sigma, Lean Production and World Class Manufacturing. These polices were created to solve some particular range of problems. We can summarize the work of these professionals as being to analyze the problem and then to select polices and tools that best fit it. When solving a production problem we usually consider some dimensions, as: processes and professionals involved, material and information flow, machinery, etc. Then, we select a specific set of practices that, when applied, will result in improvements. Sometimes polices that were developed and tested under certain conditions in a specific region are applied to a different country, with distinct environmental and cultural influences. This multi-cultural situation introduces another dimension to the solution of production issues. Trying to solve a problem without considering the cultural aspect can lead to a wrong implementation of some production management method, and consequently may not give the expected results. Thus, this research aims to analye, through a literature review, how academics and practitioners understand the role of cultural differences on the implementation of production management tools. For this, it intends to explore existing studies on production management conducted in distinct countries.
Hma Dynamic Modulus Predictive Models (a Review)

The most important hot-mix asphalt (HMA) property influencing the structural response of a flexible pavement is the HMA modulus (EHMA). Dynamic modulus concepts are reviewed. The construction of master curves for HMA mixtures is presented. The procedures are based on the fitting of a sigmoidal function. Two IE*I predictive equations are presented. The Witczak, as proposed in the new AASHTO 2002 Design Guide, and the Hirsch model. In general, both appear to be in good agreement and have similar accuracy. The Witczak predictive equation requires eight input parameters. This information is normally available from material specifications or volumetric design of the mixture. The master curve for IE*I can be developed directly by using the binder A and VTS parameters in the viscosity components of the equation. The Hirsch model needs only three input parameters, which are available from the routine Superpave mix design process. To build the IE*I master curve, a master curve for IG*Ibinder has to be developed to take into account the effect of temperature and frequency. This can be done with data obtained from Dynamic Shear Rheometer tests. Several studies are presented where the dynamic modulus predictive models are evaluated. The studies used different binders and represent typical mixtures used by different agencies. The results clearly confirm the good agreement and similar accuracy between the Witczak equation and the Hirsch model and between these models and dynamic modulus obtained from laboratory tests. In general, it is concluded that both predictive models generate sufficiently accurate and reasonable dynamic modulus estimates adequate for use in mechanistic-empirical design, at least for broad range of binders and mixtures studied.
Seismic investigations of the HDR Safety Program. Summary report

The primary objective of the seismic investigations, performed at the HDR facility in Kahl/Main, FRG was to validate calculational methods for the seismic evaluation of nuclear-reactor systems, using experimental data from an actual nuclear plant. Using eccentric mass shaker excitation the HDR soil/structure system was tested to incipient failure, exhibiting highly nonlinear response and demonstrating that structures not seismically designed can sustain loads equivalent to a design basin earthquake (DBE). Load transmission from the structure to piping/equipment indicated significant response amplifications and shifts to higher frequencies, while the response of tanks/vessels depended mainly on their support conditions. The evaluation of various piping support configurations demonstrated that proper system design (for a given spectrum) rather than number of supports or system stiffness is important to limiting pipe greens. Piping at loads exceeding the DBE eightfold still had significant margins and failure is improbable inspite of multiple support failures. The mean value for pipe damping, even under extreme loads, was found to be about 4%. Comparison of linear and nonlinear computational results with piping response measurements showed that predictions have a wide scatter and do not necessarily yield conservative responses underpredicting, in particular, peak support forces. For the soil/structure system the quality more » of the predictions did not depend so much on the complexity of the modeling, but rather on whether the model captured the salient features and nonlinearities of the system. « less
Knowledge sharing and protection in data-centric collaborations: An exploratory study

ABSTRACT Digital supply chains (SCs) and data-centric collaborations have boosted data exchange between companies and, combined with recent advancements in data science, have brought a new type of knowledge risks . This paper presents an exploratory interview study investigating knowledge risks in data-centric collaborations. The aim is to gain insights into the current perception and awareness of knowledge risks and approaches to data-centric collaborations to encounter them. The authors conducted 27 interviews with 15 experts in a two-stage semi-structured interview study. The first stage identified three kinds of approaches for managing knowledge risks in data-centric collaborations: (1) informal, (2) preventive and (3) proactive, which were validated in follow-up interviews. All three approaches lead to different perspectives of sharing and protecting knowledge within the digital SC and relate to the business model and the level of innovation within the organisation.
Stripping in HMA Mixtures: State-of-the-Art and Critical Review of Test Methods

This report presents review summaries of the state-of-the-art regarding stripping in hot mix asphalt (HMA) mixtures. The review stresses efforts concerned with methods development and evaluation, and presents a critical review of select methods including Lottman (NCHRP 246), Tunnicliff-Root (NCHRP 274), Immersion Compression, 10-Minute Boil Test, and the Nevada Dynamic Strip Method. The results of the critical review of methods indicated the following ranking order: Lottman Test, Tunnicliff-Root Test, 10-Minute Boil Test, Immersion Compression, and Nevada Dynamic Strip Test. The basis of the analysis was a proposed success/failure pattern which was developed using published data on stripping. Other products of this research include: proposed relationship between stripping theories and mechanisms, and an appended summary of findings from surveys of the users of the stripping tests.
Family ownership

This article reviews the existing literature about the most prevalent form of corporate ownership around the world: ownership by individuals—particularly founders—and families. We summarize the existing evidence about the prevalence and persistence of family ownership around the world, along with its impact on performance—both financial and non-financial—relative to other types of corporate ownership. We discuss how and why these empirical facts and findings come about—why owners in general, and family owners in particular, are critical drivers of firm behaviour and performance, and how they are able to exercise their influence over corporations in which other shareholders, such as institutional investors, and other stakeholders can also play an important role.
Live load distribution factors for exterior girders in steel I-girder bridges

LIVE LOAD DISTRIBUTION FACTORS FOR EXTERIOR GIRDERS IN STEEL I-GIRDER BRIDGES Gregory K. Michaelson In lieu of a complex three-dimensional analysis, live load distribution factors (also referred to as girder distribution factors or wheel load distribution factors) are commonly employed by bridge engineers to simplify the analysis of a bridge system. Specifically, instead of looking at the bridge system as a whole, these factors allow for a designer or analyst to consider bridge girders individually by determining the maximum number of wheels (or lanes) that may act on a given girder. The development of the relatively new distribution factors for beam-and-slab bridges incorporated in the current AASHTO LRFD Specifications are primarily the result of NCHRP Report 12-26. This report, however, does not take into account the different live load responses of interior and exterior girders. Numerous research studies have shown that the distribution of live load in a bridge system differs between interior girders and exterior girders. The current AASHTO specifications employ three methods to determine the distribution to exterior girders: a statical based procedure called the lever rule, a rigid body rotation procedure called special analysis, and an empirical equation that calculates an adjustment factor that is applied to the interior girder distribution factor. While several studies have shown that for many cases these methods do not accurately predict the load in the exterior girder little work is available to actually evaluate the distribution of live load to exterior girders. Therefore, the goal of this research is to develop new expressions for the distribution of live load to the exterior girders of steel slab-on-beam bridges. To accomplish this, a commercial finite element software package (Abaqus) is employed. The finite element modeling technique used in this project is first compared with physical data from the August 2002 field test of the Missouri Bridge A6101. Once validated, this modeling technique is then used in a sensitivity study to determine the effect of key parameters on exterior girder live load distribution. Subsequently, a parametric matrix employing these key parameters is developed and analyzed. Data correlation techniques are then used to relate the parameters which were varied throughout the course of this study to develop empirical equations for live load distribution factors.
Doing sociomaterial studies: the circuit of agency

ABSTRACT In recent sociomaterialist, materialist and post-human theorizing which foregrounds the importance of objects and bodies, ideas of consciousness and intentionality are seen as potentially tainted either with Cartesian mind-body splits or with subjectivities that are too discursively constructed. At the same time, new theories of affect as something pre-personal and corporeal further marginalize the notion of human agency. But could the pendulum have swung too far in outlawing the human in favour of the pre-human and post-human? How can sociomaterial theories be reconciled with educators’ ongoing commitment to give their pupils voice and identify effective pedagogies for teaching digital media? This paper analyses data from a study of online multimodal writing practices in a London primary school to expand current theorizing about agency. It proposes the idea of a phenomenologically-inspired circuit of (sociomaterial) agency as a way to bring back the ‘human’ and incorporate the middle ranges of agency.
The Response of Eggplant (Solanum Melongena L.) Growth Planted on Raised-Bog Peatland towards the Provision of Chicken Dung and Swallow Guano

—Eggplant (Solanum Melongena L.) is one of the agricultural commodities needed and a kind of vegetables favored because it is not only good in the taste, it also contains potassium and vitamin A which can be beneficial for the body. Eggplant production in Indonesia is low, but the need is high. So it is necessary to increase production, one of them is conducting agricultural extensification. Agricultural extensification can be carried out on land that has not been used properly, such as raised-bog peatland. On the other hand, raised-bog peatland is marginal land that is poor in nutrients and acidic in nature, so that the condition of the peatland is not supportive for plant growth. Therefore, it is necessary to add organic materials such as chicken dung and swallow guano to support the growth and yield of eggplant on raised-bog peatland. The purpose of this study was to determine the effect of chicken dung and swallow guano and their interaction on the yield of eggplant (Solanum Melongena L.) in the raised-bog peatland. This research used a group-randomized design (GRD) with 2 factors: chicken dung and swallow guano as fertilizer with 3 equal levels (a1/w1 = 5 tons/ha; a2/w2 = 10 tons/ha; a3/w3 = 15 tons/ha). The parameter observed and measured were the yield of eggplant. The results showed that the single use of swallow guano as fertilizer had a significant effect on fruit diameter and length, the quantity of fruit for each plant, the average weight of fresh fruit, fruit weight for each plant, and fruit weight for each hectare. On the other hand, the use of chicken dung as fertilizer had a significant effect on the number of fruit per plant, fruit weight per plant, and fruit weight per hectare. The results showed that the best eggplant yield component was obtained from the addition of swallow guano fertilizer at a dose of 15 t ha-1, namely resulted in a fruit weight per plant of 541,14 g tan-1 and a total fruit weight per ha of 12,88 t ha-1. Whereas in chicken dung fertilizer treatment, the most optimum dose is 10 t ha1 which can produce eggplant fruit weight per plant of 531,56 g tan-1 and 12,66 t ha-1 in total eggplant fruit weight per ha.
Ultimate Behavior Of Multiplanar Double K-Joints Of Circular Hollow Section Members

The results of a test on multiplanar double K-joints with circular hollow sections under balanced axial brace loading are reported. The objective of the test is to investigate influences of the brace diameter to chord diameter ratio /3 = diD, the transverse gap to chord diameter ratio 'I = glD, the longitudinal gap to chord thickness ratio ,. = glT and the out-of-plane angle ¢. on the static strength of the joints. These variables are varied in the following range: 0.22:0;,&;0.47, 0.04:0;'/:0;0.53, 2:0;'1:0;14 and ¢. = 60° or 90°. The influences of ,. and 'Ion the ultimate capacity of double K-joints are independent of each other. The ultimate capacity increases with the decrease of ,. , but this increase is smaller than for K-joints. The influence of 'I depends on the failure type: for a constant value of /3,the ultimate capacity increases with 'I for the failure type without local deflections of the chord wall between the compression braces and decreases for the failure type with significant local deflections of the chord wall between the compression braces. The ultimate capacity of double K-joints is compared with previous research on double K and T-joints, as well as with AWS, IIW and Cidect design recommendations. Formulae for the ultimate capacity of double K-joints are proposed based on past and present results. INTRODUCTION NOMENCLATURE Tubular structures are widely used for offshore oil drilling and production. Mostly these are trussed space frames extending from the sea bottom to just above the sea level. In such space frames multiplanar joints are unavoidable. However, since studies in the ultimate behavior of multiplanar tubular joints have started only Received December 12, 1991: revised manuscript received by the editors October 23, 1992. The original version (prior to the final revised manuscript) was presented at the Second International Offshore and Polar Engineering Conference (ISOPE-92), San Francisco, USA, June 14-19,1992.
N- and / or O- Alkylation of Quinazolinone Derivatives

Here we report on a strategy based on the capabilities of 2D NMR spectroscopy, which focuses on determining the exact structures of promising HDAC / VEGF-2 inhibitors and intermediate N- or O-alkylated building blocks for their construction. Due to which, in contrast to the erroneous conclusions of other studies, it has been unequivocally established that quinazolin-4-ones with alkyl halides under the classical conditions of two-phase catalysis: the solid phase (alkali metal carbonates) and liquid (aprotic solvents) are subjected to alkylation in the 3-N-position.
