Show moreConstruction managers use scheduling methods such as the critical path method (CPM) and linear scheduling methods (LSM) to improve the outcome of their project. CPM is a popular scheduling method that is mostly based on precedence relationships and the identification of the longest path through a network. LSMs are based on a continuous flow of resources and are used mostly on projects that exhibit repetitive characteristics. Despite the many obvious advantages of CPM, its use in construction has been limited. LSMs are much less frequently used than CPM, although the general consensus is that LSMs are quite effective in projects composed of activities of repetitive nature. Understanding the reasons why these methods are not used as extensively as expected could improve their level of acceptance in the construction industry. The link between construction scheduling methods and the tasks expected to be performed by schedulers has been an on-going concern in the construction industry. The link between construction scheduling methods and the capabilities of the scheduling staff has also been an important issue. This study proposes a combined task/staffing-technology fit model to understand why CPM and LSM are not used as extensively as expected in construction scheduling: (1) a task-technology fit model that aims to measure the extent to which a construction scheduling method functionally matches the tasks expected to be performed by the scheduling staff; (2) a staffing-technology fit model that aims to measure the extent to which a construction scheduling method matches the staff`s experience, know-how and capabilities. The models that are proposed are an answer to the lack of proper instruments for evaluating the extent to which scheduling methods are used in the industry. A questionnaire survey was administered to professionals listed in the directory of the Construction Management Association of America (CMAA) who have many years of experience in construction scheduling. Statistical analyses were performed to determine statistical significance of the differences between the level of agreement concerning task-technology fit and staffing-technology fit for CPM and LSM applications. Findings indicate that there are significant differences between the opinions of CPM users and LSM users. This means that task-technology fit is much different in CPM and LSM applications. Similarly, staffing-technology fit is also quite different in CPM and LSM applications.

Title: COMPUTATIONAL ACCESS FLOW REDUCTION EFFECT ON WALL SHEAR STRESS IN BRACHIOCEPHALIC FISTULAE

Show moreThe population of patients with end stage renal disease (ESRD) is growing at a rate higher than the global population. The only viable treatment for these patients is a kidney transplant. However, in the absence of a suitable kidney donor, renal patients are left with hemodialysis as a renal replacement therapy. Hemodialysis is facilitated through arteriovenous fistula (AVF), and the particular interest in this investigation is brachiocephalic fistula (BCF). The survival of dialysis patients depends on maintaining patency of fistula over a prolonged period of time. The extreme hemodynamic environment that is created by BCF triggers the onset of neointimal hyperplasia (NH) in most renal dialysis patients, which leads to access failure via stenosis. This is because the hemodynamics in AVF are well outside the normal physiological range. Computational fluid dynamics (CFD) along with shape optimization allows for the study of the hemodynamic parameters such as wall shear stress that have been shown to be detrimental in the future occurrence of cephalic arch stenosis. In this study, CFD modeling and identification of hemodynamic patterns was possible in three dimensions due to advanced post processing of IVUS patient-specific geometries. A method utilizing 3D CFD and shape optimization has been developed to implement Miller’s banding method used in clinical practice to evaluate its impact on WSS and onset of neointimal hyperplasia. The level of banding represented by a constriction is in fact a patient specific value and is not a trivial solution of minimum flow rate necessary to conduct hemodialysis; hence suggesting that even restoring the inlet velocity to the velocity pre-fistula creation might not reduce incidence of cephalic arch stenosis. The findings of this study support the previous hypothesis that non-homeostatic WSS distributions trigger neointimal hyperplasia and resulting venous stenosis. The important outcome is that the presented computational framework allows for evaluation of Miller's banding method for reducing the blood flow rate via surgical constriction and identification of a patient-specific banding level that restores the WSS to the normal physiological range.

Title: Method and Appartus for Forming Ultrafine Metal Powders

Show moreA method and apparatus for producing ultrafine metal powders in which a laser beam is focused on the surface of a workpiece or feedstock and moved thereacross so as to create a cavity within the workpiece through melting and vaporization that contains the metal melted to form the cavity. A subsonic pulsating blast of inert gas is directed at the cavity to atomize the molten metal, rapidly cool the resulting droplets, and transport the droplets to a collection area. The cavity formed by the laser beam is a "keyhole" of deep cavity having a depth approximately three to four times greater than its width. The focal point of the laser beam is moved across the workpiece at a rate from approximately 50 to 80 inches per minute to ensure that the molten metal remains in the cavity prior to the gas atomization. Alloy metal powders can be produced by this method of laser blast atomization providing an alloying metal at the base metal where the cavity is formed so that, upon melting of the base metal, the alloy metal will melt into solution with the molten base metal in the cavity prior to gas atomization. Additionally, nonmetallic impurities may be removed from the molten metal contained within the cavity formed by the laser beam by vaporization.

Show moreStereo Vision is one of the fundamental problems of computer vision and one of the oldest and heavily investigated areas of 3D Vision. Recent advances in stereo matching methodologies have allowed researchers to develop several stereo vision techniques. But it has been observed that most of these methodologies mainly focus on only one aspect, either the execution time or the quality of the generated depth map. While attempts to maximize the quality of the depth map have been successfully achieved, it is however observed that the execution time has increased signi cantly, thereby rendering them un t for real time implementation. In this thesis, an attempt to solve the above said problem is presented, in which we combine the e ects of two important stereo matching concepts, one attempting to increase the depth map quality, while the other being that of having an algorithmic structure so that in future, it can be used for real-time implementation. By applying hardware-friendly methods to the framework of segment based stereo matching, the method is said to achieve a good quality depth map. This work also discusses the various challenges which it takes care of plus the study of performance compared to existing methods.

Show moreIn this research, we have explored and verified the data security and real-time performance of a Secure Wireless Health Data Management (SWHDM) system applied to personal body sensor networks. Security must be considered critical for any healthrelated information system. The SWHDM examined for this study consists of multiple wireless health-related sensors, one central data coordinator called the Wireless Intelligent Personal Communication Node (W-iPCN), a custom application designed for an Android smartphone, and a remotely located central medical server. There are two major communication channels involved in wireless data transmission. We extensively studied the body sensor data for wireless data transmission. We also focused on applying cryptographic algorithms in order to provide data confidentiality, integrity and authentication. This security assessment aims to observe the performance of data encryption and decryption, and feasibility to remotely monitor patients' health in realtime. The test result based on ECG examples is favorable towards the real-time processing requirements of the system.

Show more124 participants were recruited from thirteen undergraduate psychology courses and responded to online surveys over the course of a semester, rating their instructors' behaviors, their own behaviors and experience with their course. Results supported the hypothesized main effect of transformational leadership on students' class-engagement and satisfaction with a course. Additionally, student engagement mediated the relationship between the leadership style and satisfaction. Results also indicated that transformational leadership has an indirect effect of on two measures of student performance (final course grades and students' expected course grades) through student engagement. In conclusion, the findings of this research indicate the transformational leadership has a significant and positive role in engagement, satisfaction and learning, further supporting the value of examining instructor behavior as leader behavior.

Title: ROLE OF EXTRACELLULAR MATRIX IN CELLULAR BEHAVIOR AND TISSUE FUNCTION

Show moreMatrix-dictated control of stem cell differentiation and tissue status are of considerable interest to cell biologists and tissue engineers. To create suitable biological scaffolds for tissue engineering and cell therapeutics, it is essential to understand the matrix mediated specification of cell lineage. Our study examines the role of matrix properties on cellular behavior and tissue mechanics. To this end, we studied the effect of collagen type I on stem cell differentiation and its mechanical properties within a live tissue. We altered the properties of collagen type 1 by incorporating CNT. The collagen-carbon nanotube (collagen-CNT) composite material was stiffer with thicker fibers and longer D-period. We find that the enhanced mechanical and structural properties of collagen-CNT allow for rapid and efficient derivation of neural progenitors from human decidua parietalis placental stem cells (hdpPSC). Both structure and stiffness of the matrix are important determinants of neural differentiation rate. Strikingly, the collagen-CNT matrix, unlike collagen, imposes the neural fate by an alternate mechanism that is independent of beta-1 integrin and beta-catenin. The study demonstrates the sensitivity of stem cells to subtle changes in the matrix and the utilization of a novel biocomposite material for efficient and directed differentiation of stem cells. Investigation of connective tissue disorders has led to the understanding of the important role played by collagen. So far, native collagen fibers within an intact tissue have not been examined. In this study, we employed a unique approach- histochemical staining guided high-resolution elasticity mapping- to study collagen and smooth muscle in fresh vaginal wall connective tissue. The comparative study of tissues collected from healthy pre-menopausal (pre-M) and post-menopausal (post-M) women suggest that during menopause, collagen’s structure and elasticity are subtly altered. The systematic analysis enables detection of minute changes in collagen in non-fatal conditions such as pelvic organ prolapse and other genitor-urinary disorders, where the initial symptoms are subtle and multivariate and where early diagnosis will allow non-invasive interventions and reduce incidence of surgical correction for these common disorders.
