Abstract:
Both clinical and biomechanical problems affecting the shoulder joint suggest that investigators should study force transmission into and out from the scapula. To analyze force transmission between the humeral head and the glenoid, one must know the position of the glenoid. Studies have analyzed the position of the scapula from the positions of three palpable points, but the position of the glenoid relative to three palpable points has not been studied. Dry scapulae () were subjected to X-rays and a critical angle, (which relates the plane determined by the three palpable points on the scapula to a plane containing the glenoid center and the first two palpable points) was calculated. The mean value for was degrees. The obtained allows us to determine the position of the glenoid from three palpable points. This information could be used in calculation of forces across the shoulder joint, which in turn would allow optimizing the choice of strengthening exercises.

Abstract:
The scapula plays a critical role in the association between the upper extremity and the axial skeleton. Fractures of the scapula account for 0.4% to 1% of all fractures and have an annual incidence of approximately 10 per 100,000 inhabitants. Scapular fractures typically result from a high-energy blunt-force mechanism and are often associated with other traumatic injuries. The present review focuses on the presentation, diagnosis, and treatment of fractures of the scapula. Indications for surgical treatment of glenoid fossa, scapular neck, and scapular body fractures are presented in detail. Finally, the authors’ preferred surgical technique, including positioning, approach, reduction, fixation, and post-operative management, is described.

Abstract:
The scapulothoracic articulation is a sliding junction between the deep aspect of the scapula and thoracic rib cage at the levels of ribs 2 through 7. Motion at this articulation is dynamically stabilized by a variety of muscular attachments, allowing for controlled positioning of the glenoid to assist in glenohumeral joint function. A thorough understanding of the complex anatomic relationships, including the various muscles, and bursa, is critical to the evaluation of patients presenting with scapulothoracic disorders. The snapping scapula syndrome is caused by either osseous lesions or scapulothoracic bursitis and can be difficult to recognize and treat. The purpose of this review is to discuss the anatomy of the scapulothoracic articulation with an emphasis on the pathology associated with snapping scapula syndrome.

Abstract:
Objective To verify whether reverse baseplate positioning without the support of intraoperative three-dimensional technology is within the acceptable parameters in the literature and whether glenoid bone deformity (GBD) compromises this positioning. Methods Sixty-nine reverse shoulder arthroplasties were evaluated with volumetric computed tomography (CT). Two radiologists performed blinded CT scan analysis and evaluated baseplate position within 2mm of the inferior glenoid; the inclination and version of the baseplate in relation to the Friedman line; and upper and lower screw and baseplate metallic peg end point positionings. The patients were divided according to the presence of GBD for statistical analyses. Results The two radiologists concurred reasonably in their interpretations of the following analyzed parameters: baseplate position within 2mm of the inferior glenoid rim (97.1% and 95.7%), baseplate inclination (82.6% and 81.2%), baseplate version (69.6% and 56.5%), the upper screw reaching the base of the coracoid process (71% and 79.7%), the inferior screw remaining inside the scapula (88.4% and 84.1%), and the metallic peg of the baseplate considered intraosseous (88.4% and 72.5%). Conclusion Reverse baseplate positioning without intraoperative three-dimensional technology is within the acceptable parameters of the literature, except for baseplate version and upper screw position. GBD did not interfere with baseplate positioning in reverse shoulder arthroplasty.

Abstract:
Acromion marker cluster (AMC) methods have been shown to accurately track scapula motion during humeral elevation below 90°, however, their accuracy has not been assessed in shoulder girdle motion such as clavicle protraction, retraction, elevation, and depression independent of humeral movement. The aim of this study was to examine the reliability and validity of the AMC method to record scapula orientation at end range clavicle protraction, retraction, elevation, and depression. The right scapulae of 22 female and 20 male asymptomatic volunteers were assessed with an AMC and scapula locator (SL) method during end range clavicle protraction, retraction, elevation, and depression (without humeral elevation) using an 8-camera 3D movement registration system. Measurements recorded from the AMC and SL measures showed fair to excellent agreement (ICC 0.4–0.92). While the AMC method overestimated and underestimated scapular motion in some planes compared to the SL, root mean square error between methods were low for scapular internal/external rotation (2.3–3.7°), upward/downward rotation (4.5–6.6°), and anterior/posterior tilt (3.2–5.1°), across all conditions. The AMC method was shown to be a reliable and valid measurement of scapula orientation at end range clavicle movements independent of humeral movement.

Abstract Literature has revealed the importance of quantifying resting scapular posture in overhead athletes as well as quantifying scapular kinematics during dynamic movement. Prior to this project much of the attention in throwing research had been focused on the position of the humerus without description of the positioning of the scapula. Therefore, it was the purpose of this study to present scapular kinematics during pitching in youth baseball players. Twenty-five youth baseball players (age 11.3 + 1.0 years; body height 152.4 + 9.0 cm; body mass 47.5 + 11.3 kg), with no history of injury, participated in the study. Scapular kinematics at the events of maximum humeral external rotation (MER) and maximum humeral internal rotation (MIR) during the pitching motion were assessed three-dimensionally while pitching fastballs for strikes. Results revealed that at the event of MER, the scapula was in a position of retraction, upward rotation and a posterior tilt. While at the event of MIR, the scapula was protracted, upward rotated and tilted anteriorly.

Abstract:
Background Despite the recognized importance of proper 3-dimensional motion of the scapula in throwers, minimal research has quantified scapular position and orientation in throwing athletes. Hypothesis Throwing athletes exhibit scapular position and orientation differences when compared to nonthrowing control subjects. Study Design Descriptive laboratory study. Methods Scapular position and orientation during scapular plane humeral elevation were assessed with electromagnetic tracking in a group of 21 throwing athletes and 21 control subjects. Scapular upward/downward rotation, internal/external rotation, anterior/posterior tipping, elevation/depression, and protraction/retraction were assessed. Results The throwing athletes demonstrated significantly increased upward rotation, internal rotation, and retraction of the scapula during humeral elevation. No differences in anterior/posterior tipping and elevation/depression were present. Conclusions The results indicate that throwing athletes have scapular position and orientation differences compared to nonthrowing athletes. This suggests that throwers develop chronic adaptation for more efficient performance of the throwing motion. Clinical Relevance Clinicians evaluate scapular position, orientation, and movement in throwing athletes as part of the evaluation of shoulder injuries associated with the throwing motion. The current study provides clinicians with an understanding of the types of adaptations that may be observed in normal, healthy throwing athletes.

Introdução: O Complexo articular do ombro é propício a várias patologias e disfunções do movimento que parecem estar relacionadas às alterações na orientação da omoplata. A literatura recentemente publicada enfatiza a necessidade de desenvolvimento de ferramentas clínicas medição da orientação da omoplata que sejam precisas e de fácil utilização. Objetivo: Contribuir para o desenvolvimento de um método clínico para medir a orientação da omoplata a 0º e 90º de elevação do ombro. Metodologia: Foi feito um estudo correlacional utilizando uma amostra de 20 participantes assintomáticos, selecionados por conveniência do corpo discente da ESS-IPS. Foram coletadas cinco medições lineares (M1, M2, M3, M4 e M5) por dois avaliadores independentemente em dois momentos diferentes entre as referências ósseas da coluna vertebral e da omoplata na elevação do braço a 0º e 90º no plano sagital, coronal e escapular. Foi coletada simultaneamente a orientação 3D da omoplata utilizando um dispositivo de varrimento eletromagnético (Flock of Birds) e o movimento reconstruído de acordo com as recomendações da Sociedade Internacional de Biomecânica. Resultados e Discussão: O valor das correlações entre medidas lineares e angulares da posição e orientação da omoplata foram definitos como de aceitáveis e moderados, sempre acima de 0,4 e 0,5, respectivamente. Com a elevação do MS a 0º no plano frontal, foram encontradas correlações estatisticamente significativas entre a rotação interna da omoplata com M2 e M5, e entre a rotação inferior da omoplata com M1, M3 e M4. No plano sagital, foram observadas correlações significativas entre a rotação interna da omoplata com M4, e da rotação superior da omoplata com M1 e M4. No plano da omoplata, encontraram-se correlações estatisticamente significantes entre a rotação interna da omoplata e M2 e da rotação inferior com M1. Na posição de 90º de elevação do MS, apenas M2 correlacionou-se significativamente com a rotação interna da omoplata. Conclusão: Estes resultados preliminares revelam uma promessa de um método clínico preciso e fácil de usar para quantificar a orientação da omoplata com base em medições lineares.
Abstract: Introduction: The shoulder complex, is prone to several pathologies and movement dysfunctions that seem to be related to alterations in scapula orientation. Recent published literature emphasize the need for the development of accurate and easy to use clinical tools to measure scapula orientation. Objective: Contribute to the development of a clinical method to measure scapula orientation at 0º and 90º of shoulder elevation. Methodology: A correlational study was conducted with a sample of 20 asymptomatic subjects, selected by convenience from the student community of the ESS-IPS. Five linear measurements (M1, M2, M3, M4 and M5) were independently collected separately by 2 researchers and in 2 different moments between pre-defined bony landmarks of the vertebral column and scapula with the arm at 0º and 90º of shoulder elevation in the sagittal, coronal and scapula’s plane. Simultaneously, scapular 3D orientation was collected using an electromagnetic tracking device (Flock of Birds) and motion reconstructed according to the International Society of Biomechanics recommendations. Results and Discussion: Correlations values between linear and angular measurements of the scapular orientation, were set as acceptable and moderate whenever above a cut-point of 0.4 and 0.5, respectively. With the arm at 0º of elevation, in the coronal plane, it were found statistical significant correlations between the scapula internal rotation values and M2 and M5, and between scapula’s medial rotation and M1, M3 and M4. In the sagittal plane, it were observed statistical significant correlations between scapula’s internal rotation and M4, and the scapula’s lateral rotation, and M1 and M4. In the scapula plane, statistical significant correlations were found between the scapula’s internal rotation and M2, and scapula’s medial rotation and M1. At 90º of arm elevation, only M2 was found to be statistical significant correlated with scapula’s internal rotation. Conclusion: This preliminary results unveil a promise application of an easy to use and accurate clinical method to quantify scapula orientation based on linear measurements.

Abstract:
In this report the feasibility of using a dual-tag setup in an indoor positioning system was investigated. The reason for the dual-tag setup was to be able to estimate both position and orientation. The system was designed using UWB-technology, with an time of flight trilateration algorithm to calculate the position. The orientation was then estimated from the relative position between the two tags. The system was tested both with stationary tags, but also with the tags moving along two paths. These tests were conducted for different separation distance between the tags, namely 20 cm, 30 cm and 40 cm. The result was that the mean position error for stationary tags was less than 8 cm for all separations and the mean orientation error was less than 3$^\circ$ for all separations. For the moving tag tests a decrease of the error in orientation of about 30 \% could be observed for a separation of 30 and 40 cm compared to 20 cm. However this difference is small in absolute values so more tests are needed to draw any conclusion about whether 30 and 40 cm tag separation performs better than 20 cm tag separation. The performance of the system could also be increased further by optimizing the anchor placement as well as the calibration of the antenna delays of the UWB-modules.

Abstract:
Signaling systems regulate the flow of cellular information by organizing proteins in space and time to coordinate a variety of cellular activities that are critical for the proper development, function, and maintenance of cells. Signaling molecules can exhibit several levels of complexity through the utilization of modular protein interactions, which can generate simple linear behaviors or complex behaviors such as ultrasensitivity. Protein modularity also serves as the basis for the vast protein networks that form the regulatory networks that govern several biological activities. My work focuses on the importance of protein modularity in complex biological systems, in particular the regulatory pathways of spindle positioning. The first part of my work involves the construction of a synthetic regulatory network using modular protein interactions in an effort to understand the complex behavior of the natural spindle orientation regulator Pins. Utilizing well-characterized protein domains and their binding partners, I built an autoinhibited protein switch that can be activated by a small protein domain. We found that the input-output relationship of the synthetic protein switch could be tuned by the simple addition of "decoy" domains, domains that bind and sequester input signal, thereby impeding the onset of the output response to generate an input threshold. By varying the number and affinities of the decoy domains, we found that we could transform a simple linear response into a complex, ultrasensitive one. Thus, modular protein interactions can serve as a source of complex behaviors. The second part of my work focuses on elucidating the molecular mechanisms underlying spindle positioning in the Drosophila neuroblast. I found that Pins orients the mitotic spindle by coordinating two opposite-polarity microtubule motors Dynein and Kinesin-73 through its multiple domains. Kinesin-73 also relies on its modular domain architecture to perform its duties in Pins-mediated spindle positioning, where its N-terminal half functions in coordinating cortical-microtubule capture while its C-terminal half functions as a region necessary for the activation of Dynein. Thus, modular protein design allows for the organization of spindle orientation regulators in space to achieve the complex biological activity that is spindle positioning. This dissertation includes previously published and unpublished coauthored material.

Abstract:
This thesis explores the creation and setup of a prototype that allows users of the device to interact within an indoor real world environment and a virtual environment simultaneously using high-tech common technology. The prototype is comprised of a small mobile device such as a cellular mobile phone, Raspberry Pi computer, a battery powered handheld Pico projector, and software developed for the Android OS. The software can easily be ported to other mobile and non-mobile operating systems. The mobile device must contain accelerometer, magnetometer, and gyroscope embedded sensors as well as 802.11 wireless network chip. The prototype software implements an indoor positioning system to track the current location and orientation of the prototype device in real time. It also displays a virtual world projection upon the surfaces of the real world in relation to the prototype’s physical location and orientation. Three different orientation estimation methods were tested and compared in this thesis. Accelerometer and magnetometer based method, gyroscope based method, and a combined method using a technique called sensor fusion were implemented. A multilateration approach was used for location estimation. Location estimates were calculated from the measured received signal strength of multiple 802.11 wireless network access points. The location of all wireless access points were known and fixed. Received signal strength data was converted to meters using a log distance propagation model, and tests were conducted to compare actual distance with converted distance. Tests were also conducted to compare multilateration estimates from unfiltered or raw RSS and filtered RSS data using a Kalman filter.

Abstract:
Because of the limitation of GPS indoors there is a demand for alternative methods to accurately determine both position and orientation. Previous attempts at positional tracking has required an infrastructure of hardware and sensors to provide the path of an object or person. This is not a mobile solution to a mobile problem. This project aims to answer the question if it is possible to use an Inertial measurement unit sensor for this application. It will also create a prototype device that will demonstrate the capabilities of the proposed method. The goal of the project is to reach an accuracy of ±20 cm for position and ±5 degrees for rotation. A Kalman filter will be used to filter the output from the sensor in order to get more stable and accurate readings. The results show that it is possible to determine position of ±20 cm up to 100 cm with the proposed method. An inertial measurement unit is capable of measuring rotation accuracy of ±5 degrees and a prototype has been designed and manufactured to demonstrate the method.

Abstract:
Unmanned aerial vehicles (UAV's) have recently gained popularity in military, civil service, agriculture, commercial, and hobby use. This is due in part to their affordability, which comes from advances in component technology. That technology includes microelectromechanical systems (MEMS) for inertial sensing, microprocessor technology for sequential algorithm processing, field programmable gate arrays (FPGA's) for parallel data processing, camera technology, global navigation satellite systems (GNSS's) for navigation, and battery technology such as the high energy density of lithium polymer batteries. Despite the success of the technology to date, there remains development before UAV's should be flying alongside manned aircraft or over populated areas. One concern is that UAV electronics are not as safe, reliable or robust as manned-aircraft electronics because UAV's are not certified by the FAA. Another concern for UAV operation is with control algorithms and sensors, particularly in the estimation of the aircraft state, which is the position, velocity, and orientation of the aircraft. Some problems, such as numerical stability of a control algorithm or flight in windy and turbulent conditions have only been solved for certain conditions of wind, weather, or maneuvers. Outside those conditions, the actual orientation of a flying craft can mislead to the control system, and the control system may not be able to recover without a crash. When pilots fly manned aircraft in instrument meteorological conditions, or conditions of limited visibility of the ground, terrain, and obstacles, the pilot must fly in a manner which avoids abrupt maneuvers which could disturb accuracy of the aircraft's instruments. In a UAV without a pilot, there is a need to estimate the position and orientation of a UAV in an absolute manner unambiguous relative to the Earth. The position and orientation estimate must not depend on carefully controlled flight paths, but instead the estimate must be robust in the presence of UAV flight dynamics. This thesis describes the design, implementation, and evaluation of a hardware platform for GPS based orientation sensing research. In this work, we considered a receiver with three or four RF sections, each connected to an antenna in a triangular or tetrahedral pyramid constellation. Specific requirements for the receiver hardware and functionality were created. Circuitry was designed to meet the requirements using commercial off-the-shelf (COTS) radio frequency (RF) modules, a mid-sized microcontroller, an FPGA, and other supporting components. A printed circuit board (PCB) was designed, fabricated, assembled, and tested. A GPS baseband processor was designed and coded in Verilog hardware description language. The design was synthesized and loaded to the FPGA, and the microcontroller was programmed to track satellites. With the hardware platform implemented, live satellite signals were found and tracked, and experiments were performed to explore the validity of GPS based orientation sensing using short antenna baselines. The platform successfully allows the user to develop correlator designs and explore carrier phase based orientation measurement using only software/Verilog modifications. Initial results of carrier phase based orientation sensing are promising, but the presence of multipath signal interference shows room for improvement to the baseband processing code.

Abstract:
L'orientation marché est une notion apparue dans les années 1990. Faisant l'objet d'un fort intérêt de la part de nombreux chercheurs, elle pourrait s'avérer être une réponse efficiente à la complexification des environnements respectifs des entreprises ainsi que celle des consommateurs. Pourtant, méconnu par de nombreux praticiens, ce concept fait l'objet de mauvaises interprétations, lesquelles ne reflètent pas réellement son grand potentiel stratégique. Par ailleurs, la grande majorité des recherches réalisées portent sur l’effet de l'orientation marché sur la performance globale d'une entreprise. Au travers de ce travail, nous avons ainsi souhaité analyser si, dans un contexte spécifique, l'intégration de cette philosophie d'entreprise pouvait posséder ou non un effet direct sur l'implémentation d'un outil stratégique souvent considéré comme étant l'un des fondements du marketing : le triptyque segmentation-ciblage-positionnement
Market orientation was created during the Nineties. It could be considered as an efficient answer to the complexification of the companies and consumers environments. In this state of mind, it provides a strong interest for numerous researchers. This notion is unknown and badly interpreted by a majority of practitioners, despite its important strategic potential. Moreover, the big majority of researches linked with this topic are dealing with the effect of its integration on the global performance of a company. We wanted to analyze through this academic work if in a specific context, the integration of the market orientation philosophy could have a direct effect on the implementation of a strategic tool: the segmentation-targeting-positioning process. This triptych is indeed often considered as a basis of marketing strategy

Abstract:
The process of over-positioning shows how exaggeration of positioning leads to I-prisons that limit the freedom of the self. After presenting some examples of over-positioning (pushy parents) and under-positioning (depression), the main focus is on the comparison of the former Soviet communist system that placed the other (the community) above the self (the individual), and the capitalist society in its neo-liberal manifestation that places the self above the other. In this context, the following developments are discussed: the process of marketization and economizing in modern societies and their manifestation in consumerism as forms of over-positioning, the “empty self” resulting from the combination of individualism and consumerism after World War II, the shadow side of the American Dream; the excesses of hyperconsumption in an affluent society, the psychological consequences of money orientation, and the failure of overconsumption to contribute significantly to happiness.

Abstract:
Abstract The continued rise in frequency and magnitude of cloud-based privacy breaches brings to the fore the challenges experienced by cloud service providers (CSPs) in balancing the need to maximize profit with the need to maintain data privacy. With a backdrop of the ineffectiveness of regulatory approaches to protecting privacy, this chapter explores privacy from a non-regulatory perspective—instead exploring a CSP’s approach to privacy as dynamics of control and justice. We apply control theory to represent the CSP’s compliance with privacy legislation and power over data, and we apply justice theory to represent the CSP exceeding compliance. Control theories, such as social contract theory, have frequently been applied to explore privacy challenges between organizations and consumers, as too have justice theories e.g. procedural and distributive justice. However, few studies have combined these theoretical concepts to provide a balanced view of these tensions in the cloud computing landscape. Integrating concepts from these theories, we construct a framework that can help to explain and position a CSP’s privacy orientation. Four key privacy orientations emerge in our framework, namely: Risk Managers, Integrators, Citizens and Warriors. We discuss the implications of each privacy orientation for CSPs. Our framework will enable future research to further understand, explore and compare the impact and effectiveness of each privacy orientation.

Abstract:
AbstractRecent years have seen the use of increasingly realistic electric field (EF) models to further our knowledge of the bioelectric basis of noninvasive brain techniques such as transcranial direct current stimulation (tDCS). Such models predict a poor spatial resolution of tDCS, showing a non-focal EF distribution with similar or even higher magnitude values far from the presumed targeted regions, thus bringing into doubt the classical criteria for electrode positioning. In addition to magnitude, the orientation of the EF over selected neural targets is thought to play a key role in the neuromodulation response. This chapter offers a summary of recent works which have studied the effect of simulated EF magnitude and orientation in tDCS, as well as providing new results derived from an anatomically representative parcellated brain model based on finite element method (FEM). The results include estimates of mean and peak tangential and normal EF values over different cortical regions and for various electrode montages typically used in clinical applications.
