Show moreFeature Language Extensions (FLX) and AspectJ are two sets of programming language constructs designed to enable the programmer to modularize interacting features, or equivalently crosscutting concerns, that cannot be modularized with a main stream programming language. The two approaches are quite di erent. The purpose of this thesis is to compare how e ective they are in feature integration, such as whether the already developed features will need to be modi ed. The study was conducted by integrating a set of features of the familiar computer blackjack game. The blackjack game is interesting because it has features that will execute some programs of the basic game iteratively and recursively. We found that with AspectJ we need to modify existing feature code or repeating feature code under certain integration scenarios. We discuss the underlying reasons why they occur and in some cases suggest methods to overcome them.

Show moreWe introduce a satisfiability solver for first order formulas written in a modern object oriented programming language such as Java, which is the programming language that we use to implement the solver. The variables in the first order formula can be of any data type definable with the host programming language. The first application of the solver is to detect interaction conditions among programs written in the Feature Language Extensions (FLX). Therefore, it also determines the satisfying conditions of the formula if the formula is satisfiable. FLX is a set of programming language constructs designed to allow the programmer to develop interaction features as reusable program modules [25]. Interaction detection is equivalent to automating the task of finding where to make code changes if the interacting features are implemented with conventional programming languages. The solver requires that predicates in the formula contain no functional elements. This restriction should not reduce the kind of programs that can be written in the host programming language. FLX provides language support for the solver. The language constructs allow the programmer to provide semantic guidance to the solver on the data types that they define, and the compiler to enforce the standards required of the first order formula. While the first application of the solver is to analyze programs written in FLX, it should be useful to other applications which desire such a solver to process variables used in software directly.

Show moreTitin-based passive tension is one of the mechanisms that modulate myofilament length dependent activation, the phenomenon that underlies the so-called Frank Starling Law of the Heart. The Greaser N2BA-G rat model, with a homozygous autosomal mutation in the titin gene, produce a longer isoform of titin that produce much less passive tension as well as a reduced degree of LDA. This provides a useful tool to test whether titin modulates sarcomere structure with changes in sarcomere length. Here we assessed sarcomere structure using small angle X-ray diffraction of intact, twitching papillary muscle in the diastolic phase of contraction at short and long sarcomere length. Comparison of our results from wild type and titin mutant rats indicated that the equatorial intensity ratio, I11/I10, decreases in both wild type and the titin mutant rats with increases in length indicating that the myosin heads are more associated with the thick filament backbone than the thin filament at long lengths. Analysis of the first myosin layer line shows that there is a radially inward movement of myosin heads in WT myocardium but not in the titin mutant when stretched. Difference electron density maps show the thick filament densities in wild type increases more than in titin mutant rats and that the densities of the thin filament are less in the titin mutant rats. Our data suggest, therefore, that increased calcium sensitivity at longer sarcomere length is not due to a radial extension of the myosin heads at long length. Rather, it is associated with transmission of titin-based passive tension from the thick filaments to the thin filament, resulting in increased ordering of the myofilaments at the hexagonal lattice positions requiring some sort of communicating structure, presumably crossbridges, between the thick and the thin filaments as part of the length transduction mechanism behind LDA. The X-ray diffraction studies showed that there are gross troponin structural cahnges when muscle is stretched indicating that troponin is an important regulator of LDA in the myofilaments. But the precise way in which troponin regulates muscle contraction is only partly understood. In the research reported here, we investigated the effects of cTnI phosphorylation of sites in human cardiac tissue using site-directed mutagenesis. Serine and threonine were replaced by aspartic acid (D) or glutamic acid (E) to mimic the phosphorylated state. Six recombinant human cardiac troponin complexes (hcTn), containing either hcTnI-WT, hcTnI-S5/6D, hcTnI-S23/24D, hcTnI-S42/44E, hcTnI-T143E and hcTnI-S150D were exchanged into skinned human cardiac fibers. Force and ATPase activity was measured as function of [Ca2+] at short and long sarcomere length (SL=2.0 and 2.3um). We found that LDA in the hcTnI-S150D substitution was attenuated, and was unchanged with the other sites. CD, as indexed by tension cost was decreased for hcTnI-S42/44E and hcTnI-S150D, and was unaffected for the other site substitutions. While some of these results were consistent with previous findings form rodent myocardium, others were not, suggesting that one should use caution in extrapolating from results in rodetn cardiac tissue to human cardiac tissue.

Show moreNowadays, various commercial polymers such as low density poly(ethylene) (LDPE), poly(propylene) (PP), and Nylon, may contain or are fabricated with molecular and/or nano-sized inorganic filler elements. These fillers elements often modify, enhance or bring desired changes to the native properties of these polymers. However, these additives also have the potential to interact with the physical environment. For any new additive, it is important to assess and evaluate the potential consumer exposure under intended conditions of use. This thesis reports on the preparation of model polymer samples fabricated with various molecular and nano-sized filler elements (exfoliated clays, quantum dots, and organic colorants) to help evaluate factors affecting the rate of migration and the potential consumer exposure associated with these materials. One of the main aims of this project is the development of methods to incorporate organic and inorganic additives into polymers relevant to food packaging and medical devices using a laboratory scale twin-screw micro-compounder. Some of the samples prepared via optimized methods include (1) 1, 3, 5, and 7 wt.% Montmorillonite in LDPE; (2) quantum dots (QDs) spanning a size range of 3-8 nm into LDPE; and (3) 1-2 wt.% colorant-loaded polymer films, where the colorants include phthalocyanine blue, phthalocyanine green, quinizarin blue, manganese (II) phthalocyanine and titanium (IV) oxide, and the host polymers include poly(propylene), poly(carbonate), Nylon 12, and PEBAX (poly(ether-block-amide)). In addition to optimizing methods for composite fabrication, the properties of these materials were analyzed using many techniques, including differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), inductively coupled plasma-atomic emission spectroscopy (ICP-AES), and Fourier transform-infrared (FT-IR) spectroscopy. Migration experiments were carried out to evaluate the interaction of samples with model food and environmental systems. This research was instrumental to support efforts to understand the mechanisms of potential exposure to polymer additives.

Show moreObesity is a major public health concern throughout the world. 10-38% of those who receive the most effective treatment for obesity--bariatric surgery--fail to lose substantial weight at all or over time regain weight that was lost post-surgery. The current study tested a model of autonomous motivation for diet and exercise, physical activity, emotional eating, and adherence to post-surgery recommendations (e.g., eating behaviors, fluid intake, dietary supplement management, etc.) in post-bariatric surgery patients. It was hypothesized that autonomous motivation for diet and exercise post-surgery would predict adherence to post-bariatric surgery recommendations. Further, it was also hypothesized that physical activity and emotional eating would in serial partially mediate the relation between autonomous motivation for diet and exercise and adherence to postsurgery recommendations. Results found a positive relation between autonomous motivation for diet and exercise and adherence to post-bariatric surgery recommendations; however, there was no evidence to support mediation via a path from physical activity to emotional eating. Implications for treatment are discussed.

Show moreThis thesis presents a scenario-reduction technique to solve stochastic security- constrained unit commitment (Stochastic SCUC) problems. The uncertainty of wind power generation is simulated by the Monte Carlo (MC) method. The Stochastic SCUC problem is formulated as a mixed-integer linear programming (MIP) problem and the large-scale optimization problem is decomposed into one master problem and several tractable subproblems for each scenario. Computational burdens for solving scenarios-based Stochastic SCUC are mainly depend on the number of scenarios and a scenario-reduction technique is applied to reduce the computation burdens. The numerical results of a 6-bus system show the effectiveness of the Scenarios-Reduction Techniques for solving the Stochastic SCUC problem. Index Terms—Power System Operation, Stochastic Programming, Stochastic SCUC, Monte Carlo Stimulation, Scenarios Reduction.

Show moreParenting has been shown to play a crucial role in the development of child emotional and behavior problems. Typically, however researchers use “mothering” as a proxy for “parenting” and the role of fathers has been relatively ignored (Phares, Lopez, Fields, Kamboukos, & Duhig, 2005). Data also suggest that the gender of both the parent and child influence the relationship between parenting and children’s emotional and behavior problems. To date, however, there is no study in which both the direct effects and the 3-way interaction between paternal and maternal parenting, child gender and both internalizing and externalizing problems have been examined. The aim of this study, then, was to examine the direct and interactive relationships between maternal positive parenting, paternal positive parenting, and child gender on children’s externalizing and internalizing problems. Archival data from a subsample of the 1,103 54-month-old children and their parents who participated in wave 2 of the NICHD Study of Early Childcare were used (NICHD, 2001). Selection criteria for this subsample were that both parents participated and were co-residing. This resulted in a pool of 664 children (338 boys, 326 girls), mothers and fathers (96% married), who were predominantly (86%) White. Positive maternal and paternal parenting were assessed by a factor-analytically-derived score based on observer ratings of a semi-structured interaction paradigm, the Three Boxes Task (NICHD Early Child Care Research Network, 1999). Child emotional and behavior problems were assessed by an averaged composite of maternal- and paternal-reported CBCL externalizing and internalizing scores (CBCL; Achenbach, 1991). Results from moderated hierarchical regression analyses indicated that there was a direct relationship between maternal parenting and child gender in predicting children’s externalizing scores. Specifically, lower levels of maternal positive parenting and being a girl predicted higher externalizing scores. No direct relationship between paternal positive parenting and externalizing scores was found. In addition, there was not a significant, direct relationship between maternal positive parenting, paternal positive parenting or child gender and internalizing scores. Results also indicate that there was a significant, but small three-way interaction between maternal positive parenting, paternal positive parenting and child gender in predicting externalizing and internalizing scores. Examination of interaction graphs suggested that for girls whose mothers display low levels of positive parenting, higher levels of positive paternal parenting may reduce the risk of internalizing and externalizing problems. For boys, having two parents with higher levels of positive parenting seems to serve as a protective factor, reducing the risk of emotional and behavior problems. These data suggest that fathers’ parenting does make a difference, and that both the gender of the parent and the child are important factors to consider when examining the relationship between parenting and children’s outcomes.

Show moreThe aim of this study was to examine whether psychological distress and trait anxiety were related to positive (i.e., smiling and surprised) and negative (i.e., worried and sad) facial expressions and gaze towards the fetus during routine ultrasound procedures in the second trimester of pregnancy. Assessment of mood symptoms during the second trimester of pregnancy is important because it is when depression begins to have a negative impact biochemically, which may lead to adverse postnatal outcomes. Participants included a diverse group of 70 women in their second trimester of pregnancy. The Depression Anxiety Stress Scales (DASS-21) and the State Trait Anxiety Inventory (STAI), Trait Form were used to assess psychological distress and trait anxiety, respectively. Videos of participants’ faces during their ultrasound examination were coded to assess facial expressions and gaze towards the fetus. Results of regression analyses indicated that higher levels of distress and trait anxiety were related to fewer smiles. Higher levels of distress also were related to longer durations of sad expressions. There was not a relation between duration of gaze towards the fetus and levels of distress and trait anxiety. These findings suggest that women’s negative facial expressions during routine sonograms may show that they are feeling distressed, and could indicate the need for more formal screening for depression and anxiety symptoms.

Show moreThe presence of externalizing symptoms in children with Autism Spectrum Disorders (ASDs) is a common occurrence. Additionally, recent research has established high rates of internalizing symptoms within this population. This study examined the frequencies of internalizing and externalizing symptoms according to parent, teacher, and self-report of children and adolescents with an ASD. The agreement between sources on both types of symptoms was examined, as well as the relationship between agreement rates and type of symptom, age, and diagnosis (Autism, Asperger’s Disorder, Pervasive Developmental Disorder-Not Otherwise Specified). Participants included 77 children and adolescents (8-18 years) who had been diagnosed with an ASD, their parents, and teachers. Parent, teacher, and self-report were measured using the internalizing and externalizing composites of the Behavior Assessment System for Children, 2nd edition (BASC-2; Reynolds & Kamphaus, 2004). Results indicated high rates of both types of symptoms endorsed by all three sources. However, parents reported significantly more symptoms than their children, with symptom endorsement by teachers in between these. Although agreement rates were low across all sources, there was higher agreement for externalizing symptoms compared to internalizing symptoms. Additionally, age was found to impact agreement rates: adolescents’ selfreport of symptoms significantly correlated with parents for both types of symptoms and with teachers for externalizing symptoms, while children’s self-report of symptoms did not significantly correlate with the other sources for either type of symptom. Contrary to hypotheses, age and diagnosis were not related to the rate of self-report. Implications of the findings are discussed.

Show moreThe complex factors associated with assessment and treatment of pediatric concussion are still not well understood. Currently, the majority of pediatric concussion research focuses on sport-related concussions (SRC), despite the large number of youth who sustain non-sport-related concussions (NSRC). Because participation in sports represents an important pre- and post-injury factor that can affect postconcussive outcomes for youth, the aim of this study was to examine differences in youth diagnosed with SRC compared to NSRC (e.g., fall, gym injury, motor vehicle accident, accidental blunt trauma, assault). Participants included 298 children/adolescents (8- to18-years) who sustained a concussion (212 = SRC). Neuropsychological measures and questionnaires were administered to assess working memory (Auditory Consonant Trigram Test; ACT), memory (Immediate Post-Concussion Assessment and Cognitive Testing; ImPACT), attention (Conners’ Continuous Performance Test, 2nd Ed.; CPT-II), reading and math fluency (Woodcock-Johnson, 3rd and 4th Ed.; WJ-III; WJ-IV), and parent- and self-report of executive function (Behavior Rating of Executive Function; BRIEF) and internalizing symptoms (Behavior Assessment System for Children, 2nd Ed.; BASC-2). A MANCOVA (days since injury as covariate) was conducted to examine differences between youth with SRC compared to youth with NSRC. As predicted, youth with NSRC performed significantly worse than youth with SRC on the ACT, ImPACT Memory, and WJ math fluency. Contrary to hypotheses, there were no differences between groups on the CPTII, WJ reading fluency, BRIEF, or BASC-2. Results of this study provide clinically relevant information regarding how mechanism of injury impacts postconcussive recovery in youth.

Show moreNoroviruses are the leading cause of acute nonbacterial gastroenteritis in humans. Bivalve mollusks bio-accumulate norovirus as they feed. High pressure processing (HPP), a non-thermal processing technology, can inactivate microorganisms in foods while preserving flavor, appearance, nutritional value, and extending shelf-life. In the present study, we have systematically investigated the effect of parameters such as temperature, salinity and product composition on the efficacy of HPP for inactivation of human norovirus surrogate. For temperature analysis MNV-1 suspended in aqueous media, oyster homogenate, and bio-accumulated in whole oysters were treated with pressures varying from 200-500 MPa at 4, 10, and 20oC with a hold time of 1 minute. In media, a 4-log10 reduction was observed upon treatment at 300 MPa for 1 minute at 4oC, whereas pressures of 400 and 500 MPa were required for a comparable reduction at initial processing temperatures of 10 and 20oC. Colder temperature promoted higher reduction in virus titer at a given pressure. Addition of 1, 2 and 3% (w/v) sea salt to aqueous media provided significant baroprotective effect at colder temperatures. While pressure of 300 MPa for 1 min at 4oC was sufficient to achieve 3-log10 reduction for MNV-1 suspended in 1% (w/v) sea salt media, the same conditions resulted in only 1.4-log10 reduction for MNV-1 suspended in 3% (w/v) sea salt media. However increasing processing temperature the minimized the baroprotective effects. Similar results were observed for the effect of food matrix on virus survival, with significant baroprotective effect at colder temperatures and a minimal impact of matrix on increasing processing temperature. For initial processing temperature of 4oC a 300 MPa treatment with a hold time of 1 min resulted in a 4-log10 reduction for MNV-1 suspended in aqueous media, 3.35-log10 reduction in oyster homogenate, and <1-log10 reduction in whole oysters. Whereas at higher initial processing temperatures of 10 and 20oC the difference in reduction between matrices was insignificant. A comparison of temperature v/s salinity and temperature v/s composition revealed that effects of temperature far outweighed the impact of product properties (salinity and composition).Whole oysters seeded with MNV-1 treated at 350 MPa for 1 min at 4oC was found to have a 4-log10 reduction, while MNV-1 suspended in aqueous media at 20oC on similar treatment had a 0.5-log10 reduction. Similarly MNV-1 suspended in aqueous media with 3% salt when treated with 400 MPa for 1 min at 4oC resulted in a 5-log10 reduction, whereas MNV-1 suspended in aqueous media at 20oC on similar treatment had a 1.9-log10 reduction. Oyster processors should use refrigerated temperature to achieve higher reduction in virus titer at lower pressures.

Show moreThis project focuses on building a three-dimensional high quality "mesh" for scientific simulations. Since the quality of the mesh affects the accuracy and convergence of numerical systems, having a high quality mesh is one of the most important requirements for conducting numerical simulations. Currently, most of the software packages cannot theoretically guarantee the quality of the mesh generated. The purpose of this project is to implement a selected set of algorithms that have a theoretical quality guarantee in order to study their practical performance compared with heuristics-based methods. We expect that peer researchers in various fields could use the software developed to conduct scientific simulations. In addition, the developed software will also provide the building block for later numerical simulation systems and computer graphics related systems. The major activities of the project are to acquire interdisciplinary knowledge related to computer science and other engineering departments. This project provides students from engineering and other fields with knowledge of computer science, including programming, algorithm design and analysis; and provides students from computer science with knowledge of scientific simulations and how to apply their knowledge to solve practical engineering problems.

Show moreVietnam is a relatively small and populous developing country. Over the past several decades, the change in the country’s market economy and the population growth have greatly affected the lives, activities, and the demands for heath care as well as impacted the healthcare system. Since 1994, the time when the United States abolished the trade embargo against Vietnam, the economic development and the growth of the healthcare system in the country have been extraordinary. Even though substantial investment has been obtained from the Vietnamese government, limitations remain in the physical facilities in the healthcare system as well as in the facility design. Designing a new general hospital is a complicated process and requires a lot of attention and knowledge from a design team. Generally, the design process consists of two phases: a planning phase and a design phase. The planning phase is extremely important and will decide the success of the general hospital. G D Kunders, an Indian professional hospital administrator and a healthcare facility planner, has stated “Failing to plan is planning to fail” (Kunders 2004, 61). The main objective of this dissertation, “HOSPITAL FACILITY DESIGN: A GUIDE TO SPACE PLANNING FOR A NEW GENERAL HOSPITAL IN VIETNAM,” is to produce a guide that will be a reference source for the Vietnamese government to improve the current standard for hospital design. As a reference source, the proposed guide can be used as a tool to assist Vietnamese architects and other professionals in healthcare design areas in improving the quality of the hospital planning and design in Vietnam. This dissertation also aims to be a teaching reference source for architecture educators to use in their instruction at universities in Vietnam and a learning resource to help architecture students understand requirements for spaces in a general hospital as well as how a general hospital functions so they can better plan and design it. The proposed guide is set in an arrangement that can help educators and students without strong backgrounds in hospital design to easily understand how to plan a new general hospital. The research methods used in this dissertation are (i) document reviews, (ii) qualitative research based on Post-occupancy Evaluation (POE), and (iii) comparative analyses. The findings are used to create a guide to space planning for a new general hospital to use to improve the current Vietnamese standards, TCVN 4470: 2012, General Hospital - Design Standard, in hospital planning and design for Vietnam. This dissertation consists of eight chapters, which include Chapter 1 - Introduction, Chapter 2 - Literature Review, Chapter 3 - Problem Statement, Chapter 4 - Methodology, Chapter 5 - Data Analysis, Chapter 6 - Findings, Chapter 7 - A Guide to Space Planning for a New General Hospital in Vietnam, and Chapter 8 - Conclusion.

Show moreAs demand for fossil fuel increases and availability decreases, energy consumption reduction in building becomes critical component of a city’s comprehensive energy strategy. The performance of a building’s envelope is pivotal to the energy consumption of office buildings and it must mediate between external climate conditions and people’s comfort. By optimizing a buildings envelope, the heat gain or loss of a building can be manipulated and it can reduce energy consumption. In Dhaka, a widespread desire for office building with glazing areas far greater than the percentage required achieving comfortable thermal and light levels, with high solar transmittance, is directly at odds with the need to curb cooling-related energy use. When addressing energy efficiency in a building, it is necessary to account for local climate first and foremost to define the thermal comfort condition. This determines the energy demand and consumption. Passive cooling and natural ventilation, when combined with appropriate window ratios and sun shading strategies, can reduce mechanical system energy demands significantly. This research presents a workflow that integrates adaptive thermal comfort, natural ventilation and envelope optimization to develop a pre-policy statement as a guideline for energy efficient office buildings in Dhaka, Bangladesh. First, a common practice baseline model was developed from data collected from energy audits to gain a clear understanding of the energy consumption in typical existing office buildings in Dhaka. Adaptive Comfort Algorithms from EN15251 and ASHRAE 55 were used to calculate variable set-points related to running mean and monthly mean xv of the outdoor temperature respectively. Variable set-points have been used in EnergyPlus AirflowNetwork to determine the potential energy saving of adaptive comfort control strategy of HVAC equipment and for encouraging natural ventilation envelope strategies to create comfortable indoor environment in the local climatic context of Dhaka. A method of envelope optimization was developed by combining an optimization tool with a building energy simulation tool to determine the optimum solution for improving building envelope performance. GenOpt, a generic optimization program, has been coupled with EnergyPlus for this optimization. Then, the values of envelope and glazing parameters for optimum energy performance were determined using this automatic optimization method. The reduction of a building’s energy consumption was also addressed with regards to capital and operational costs. An economic analysis was performed to establish a correlation between energy saving and capital cost increase associated with the energy-efficient envelope measures. This research shows that significant reductions in energy consumption are possible with the application of fundamental, but not complicated, changes to local building codes and establishment of a comprehensive energy conservation code. This reduction could be even greater if inhabitant behavior can be changed, if users start to take more responsibility for their interaction directly with a building’s envelope and systems to have some degree of control over daily comfort. Technology and design innovations should be utilized for adaptive threshold of appropriate, responsive architecture.

Show moreWiMAX emerged as one of the important Broadband Wireless Access (BWA) networks based on OFDMA technology and is anticipated to be an alternative to wired broadband networks. WiMAX supports different emerging applications with different Quality of Service (QoS) requirements like voice over IP (VoIP), video conference, voice conference and online gaming. Those emerging wireless applications have high throughput demand and impose a challenge to the underlying Radio Access Network (RAN) scheduling algorithms. Efficient allocation of WiMAX shared resources like subchannels is critical to meeting the high throughput demand. The WiMAX resource allocation algorithms determine which users to schedule, how to allocate subcarriers to them, and how to determine the appropriate power levels for each user on each subcarrier. In WiMAX, the DL TDD OFDMA subframe structure is a rectangular area of N subchannels × K time slots. Users are assigned rectangular bursts in the downlink subframe. The burst size varies based on the user’s channel quality and data to be transmitted for the assigned user. In this dissertation we study the problem of assigning users to DL bursts in WiMAX TDD OFDMA system with the objective of maximizing downlink system throughput for the PUSC subchannelization permutation mode. We show that finding the optimal burst assignment that maximizes throughput is NP-hard. In this dissertation,We study this problem following two distinct approaches: (1) Integer Programming approach: we formulate the problem as an IP problem and then relax it to LP, we propose different methods to resolve conflicts resulting from the LP relaxation and through extensive simulations we compare the performance of the proposed conflict resolution methods to the optimal solution. (2) Best Channel approach: we propose several efficient and effective methods to assign bursts to users based on channel quality, we prove that our Best Channel burst assignment method achieves a throughput within a constant factor of the optimal and through extensive simux lations with real system parameters, we study the performance of the Best Channel burst assignment method. To the best of our knowledge, we are the first to study the problem of DL Burst Assignment in the DL OFDMA subframe for PUSC subchannelization permutation mode taking user’s channel quality into consideration in the assignment process.
