The increasing computational demands in SONAR processing chains lead to the choice of heterogeneous architectures based on GPGPU. The complexity of these architectures makes algorithm implementation challenging for individuals who are not specialists in both the application domain and parallel programming. This thesis aims to address this issue by leveraging task-based programming concepts. Static code analysis methods allowed us to group function calls on a GPU to limit certain overheads by increasing task granularity.To extend this approach to enable the utilization of multiple GPUs while controlling memory usage, we explored a moldable task model. This was instantiated into a new OpenMP directive that unifies several older parallelization directives. In this model, moldable tasks or sub-tasks retain the ability to have dependencies. The design of a prototype executive support for managing these moldable tasks focused on load balancing on a heterogeneous architecture and defining an algorithm to detect dependencies between such tasks. Experiments on a SONAR processing beamforming algorithm and the Cholesky factorization algorithm highlighted the method's benefits and some weaknesses in the implementation choices

Abstract Master Degree Project. Business Administration and Economics Programme, Linnaeus University, Logistics, 4FE05E, Spring 2011. Authors: Alexander Avander and Erik Robertsson Supervisor: Peter Berling Title: Batch size policy Thule Vehicle Solutions - A case study in Hillerstorp Background: The Company has currently no clear batch size policy and batch sizes are an area that has been recognized with potential earnings within the company. A project to map two flows (a high volume and a low volume) and suggest a new cross functional batch size policy has been initiated. Purpose: The purpose of this project is to, with the help of a current state map, propose a new cost effective and cross functional batch size policy for the business unit car accessories and compare this to the present batch size policy to show possible earnings. Method: This project uses a qualitative approach to show the effect of batch sizes with data supplied from the Thule Sweden AB and researched through the Linnaeus University’s recourses. Findings: Thule Vehicle Solutions should be able to remove several inventories that have been caused by a batch size policy where whole pallets are preferred. A batch size policy where one batch size is used to the semi-finished inventory and another size, part of first batch size, from that inventory until the finished-goods inventory has been suggested as a cross functional batch size policy. This suggestion has been tested and in four different versions was found more cost effective than the current policy. Using smaller batch sizes in the suggested batch size policy decreased inventory levels and lead times. However, the current, larger batch size was more optimal as the holding costs are low and the set up costs are high. Key words: Batch size, batch size costs, cross functional, inventory control, lean management, production flow, supply chain integration, transportation costs, value stream mapping.

The simulated verifications and validations of the neural-network rate-function (NNRF) and the hybrid neural-network rate-function (HNNRF) approaches to modeling the batch reactor systems are provided. In chemical processes, some measurements may not be obtainable easily, and the designed NNRF model does not embed these state variables in the built dynamic model. To overcome this problem, the approximated physical model could be combined with the NNRF model to give the hybrid neural-network rate-function (HNNRF) model. The sequential pseudo-uniform design (SPUD) is used to locate desired but limited experiments to provide the NNRF and HNNRF models of the testing batch reactor systems with rich information. In this research, the NNRF model was applied to build the dynamic models of (a) the series-parallel reactions and (b) the submerged cultivation of monascus anka carried out in batch reactors; whereas, the HNNRF model was applied to a simulated polymethyl methacrylate (PMMA) solution polymerization system. The performance of the NNRF or HNNRF modeling approach is quite acceptable and can be applied to determine the optimal operating conditions of the processes.

Abstract In today’s world of intense financial competition, chemical process must be optimized quickly if they are to become successful. These successful processes must continue to be operated optimally if they are to retain their competitive edge. However, with the need of time-to-market in the changing marketplace, one could not afford to spend much time in determining the detailed mathematical model of the complex batch process in a short time period. In this research, underlying experimental design algorithms for designing optimal batch profiles in a sequential fashion are addressed. The design technique, composed of the hybrid function approximation and the Taguchi’s method (orthogonal array), is developed to determine new design profiles in the next run. The hybrid type of the function approximation consists of two parts which can be applied together or independently: a coarse and smooth approximation which uses global features of the functions, and a fine and sharp approximation which uses local features of the functions for partitioning. The partitioning is based on the projection of the profile onto a small set of global and local basis functions, compressing the profile information into a few projection coefficients. The optimal profile can be obtained if the location of the coefficients of the functions is properly adjusted in the function space. The Taguchi approach is used to design and analyze the outcomes of each experiment design in order to lead the next new run. To reduce the number of experiments in each run, based on the effect of each coefficient, a search procedure and a forbidding strategy are proposed for adjusting the design coefficients and freezing the undesired coefficients. Without the prior knowledge of the batch process, the proposed method, by using information from the previous batches, can update and modify the profiles that are applied to the subsequent experiments. The utility of the proposed method is illustrated through three end-point optimization problems, including a non-differential system, a polymerization batch reactor and a fed batch process. The comparison with other optimization methods are also made. The results of the different cases show good performance of the proposed method in comparison with those of the other methods which require the use of the given complicated models involving the chemical reactions.

A simulated verification and validation of the proposed hybrid neural-network rate-function (HNNRF) approach to modeling a batch polymerization reactor system is provided. In a chemical process, some measurements may not be obtainable easily, and the designed NNRF model does not embed these state variables in the built dynamic model. To overcome this problem, the approximated physical model is combined with the NNRF model to give the hybrid neural-network rate-function (HNNRF) model. In this study, a sequential pseudo-uniform design is used to locate desired experiments to provide the HNNRF model of a batch polymerization reactor with rich information. Transformation of the HNNRF dynamic model into a feed-forward artificial neural network (FANN) static model reduces the computation time in determining the optimal operation conditions base on the random search method. An optimal temperature trajectory and initial loading of the initiator for achieving the molecular weight distribution control can be obtained accordingly.

The objectives of this research were to determine the optimum fermentation condition by using the content of (1→3)-β-D-glucans and different molecular weight of polysaccharides as the index of the immunomodulating effects. Black soybean was used as the major cultivating media for Ganoderma lucidum with addition of different substrates including Astragalus membranaceus, glucose and polyoxin-B during fed-batch fermentation. Different concentrations of ethanol were used to separate the fermented filtrate into two parts: large and small molecular weight polysaccharides solution, which were further used to test the inhibitory ratio using leukemic U937 cell and the content of TNF-α, IL-1β and IFN-γ in the conditioned medium. The results indicates that during cultivation of G. lucidum using the feed of A. membrabaceus gives high content of (1→3)-β-D-glucans with better immunomodulating effects. Using different ethanol fraction of polysaccharides, it was observed that 40% ethanol separate the large molecular weight of polysaccharides out of the fermented filtrate. Also these large molecular weight polysaccharides solutions were having higher contents of (1→3)-β-D-glucans, and better immunomodulating effects then the small molecular weight of polysaccharides solutions.

A simulated verification and validation of the hybrid neural-network rate-function (HNNRF) approach to modeling batch reactor systems is provided. In chemical reactor processes, some measurements may not be easily obtainable, and the designed neural-network rate-function (NNRF) model in the previous work of our laboratory did not propose a method to include the state variables for the suggested dynamic model. To overcome this difficulty, the approximated mechanistic equations characterizing these immeasurable state variables could be incorporated into the NNRF model to form the hybrid neural-network rate-function (HNNRF) model. The sequential pseudo-uniform design (SPUD) is used to locate the sufficient but limited experiments to provide the HNNRF model with rich information. In this research, the HNNRF modeling capability over a large operating region was evaluated employing a simulated polymerization reactor system. In addition to the comparative benefit of short time expenditure for building the model, the performance of the identified HNNRF model is quite acceptable in the face of noisy measurements and the identified model could be applied to determine the optimal recipe or the operating conditions of the reactor systems.

This study describes the screening of 13 commercially-available plant extracts for pharmacological activity modulating vascular function using an endothelial cell model. A French maritime pine bark extract (FMPBE) was found to have the greatest effect upon nitric oxide availability in control (181% ± 36% of untreated cells) and dysfunctional cells (132% ± 8% of untreated control cells). In healthy volunteers, the FMPBE increased plasma nitrite concentrations 8 h post-consumption compared to baseline (baseline corrected median 1.71 ± 0.38 (25% IQR) and 4.76 (75% IQR) µM, p < 0.05). This was followed by a placebo-controlled, healthy volunteer study, which showed no effects on plasma nitrite. It was confirmed that different batches of extract had been used in the healthy volunteer studies, and this second batch lacked bioactivity, assessed using the in vitro model. No difference in plasma catechin levels was seen at 8 h following supplementation between the studies (252 ± 194 nM versus 50 ± 64 nM, p > 0.05), however HPLC-UV fingerprinting showed that the new batch had a 5-15% in major constituents (including procyanidins A2, B1 and B2) compared to the original batch. This research describes a robust mechanism for screening bioactive extracts for vascular effects. It also highlights batch variability as a significant limitation when using complex extracts for pharmacological activity, and suggests the use of in vitro systems as a tool to identify this problem in future studies.

This paper proposes an innovative factory planning methodology to achieve the objectives that were defined by Flexitallic for the future expansion of the Thermiculite production line. The concepts under investigation extend to the analysis of flow benefits and restrictions considering product features and demands addressed in a proposed Batch/Flow Comparative Matrix. Furthermore, this paper introduces the Quality Function Deployment (QFD) concept to support the manufacturing line design using a mechanism of incorporating commercial awareness in all stages of the product deployment. The original QFD ensures process planning by bringing parts deployment into parts characteristics through the House of Quality. This study renews the original QFD by developing the Strategic Alignment of Quality Function Deployment (SAQFD) to achieve proactive management of Houses III and House IV. The case study demonstrates the utilization and applicability of the proposed methodologies, and demonstrates their importance during the design of a high volume production line.

Crystallization is a widely used process for liquid solid separation. The products from this process are crystals, which can be described by a distribution function called “crystal size distribution function (CSD)”. The properties of the crystals affect the efficiency of downstream process, such as filtration or drying. During the process both crystal nucleation and crystal growth happens, and most of the time, the crystal nucleation is undesirable. A well-controlled crystallizer can produce crystals with less crystal nucleation. Researchers have optimize a crystallization processes by improving the seed properties or the cooling policy. In both cases an objective function is required. In this work we compare the objective function that researchers have used, to see which objective function is best when optimizing the cooling policy for a batch crystallizer. The result shows that some of the objective functions are minimized by producing a large amount of nuclei. However, for a seeded batch crystallizer the idea is to grow the seed crystals while suppressing the nucleation. Moreover, in industrial practice, the product crystals would probably be filtered so that fines (nucleated crystals) would be removed. Therefore, for each objective function we also determine the objective value after the nucleated crystals are removed, to see whether the result from each objective function is still the best. After the analysis we conclud that the objective function “minimizing the nucleated crystal mass” is better than others. In this work we also discuss the utility of changing seed properties when using “minimizing weight coefficient of variation” as objective function. We found that if the seed distribution is too wide, the system would be more likely to generate a narrow distribution crystal by excess nucleation. To prevent excess nucleation and achieve a narrow product CSD, a large seed loading and a narrow seed distribution helps. Finally, we also considered the effect of using different nucleation parameters. We changed the exponent on third moment term in nucleation rate equation. The result shows that for higher value of the exponent, the nucleation rate is suppressed, and the performance is better when the growth rate trajectory is optimized using the objective function “minimizing nucleated crystal mass.” The optimized result also mention that for higher value of the exponent on third moment term in nucleation rate equation, higher growth at the beginning of the batch is desirable.

For those persons in a persistent vegetative state or handicapped persons, the need to help taking a bath is an indispensable demand for daily life. Generally speaking, it always requires some kind of auxiliary devices such as bath seat or bath bed to help cleaning up in order to achieve the purpose of bathing. Though the number of chronic disease and persistent-vegetative-state patients gradually increases every year, the human resources in nurse and care-givers do not keep up with and result in the decrease the quality of daily care such as bathing. Using bath seat probably meet some safety concern and some part of patient’s body would not be easy to clean. Therefore, bath bed becomes a better choice. Currently the commercial bath bed does not provide the function of turn-over to assist in cleaning of patient’s back. It is the main purpose of this design study to design a bath-bed with the function of turn-over to reduce the demand of care-givers. Firstly, in this study, the related literature review is taken to classify and analyze in order to understand the key factors, kinematics and the advantages and disadvantages of current related bath-bed design. In the meantime, visiting the nursing homes and hospitals to observe how care-giver helps a patient in bathing and some special bathing techniques. Thereafter, a conceptual design of bath bed with function of turn-over is presented. The mechanisms of this novel design include: the folding mechanism of inner bedplate, the folding mechanism of outer bedplate, the retractable mechanism of bed frame. The 3D model of this novel design has been set up in Solidworks software. The interference test, dynamic simulation and stress/strain analysis have also been performed via the simulation function of Solidworks software. The preliminary results have confirmed the feasibility and safety of this new design. It hopes to let the care-givers or family members independently help the patient or elder people to take bath by using this novel bath bed.

Quantum correction is necessary when calculating dissipative quantum dynamics based on results from classical molecular dynamics simulation in which quantum effects are ignored. Quantum correction has been used in many fields to make use of classical trajectories in quantum simulations, such as calculation of infrared spectra. However, in the context of excitation energy transfer in molecular system, the need of applications of quantum corrections is less discussed. In this study, we examine four quantum correction methods, including the Harmonic method and the Standard method proposed by other groups previously, and the Fitting method and the Prony method proposed by us. We aim to elucidate the performance of the correction by the four correc- tion methods in order to properly apply them to simulating excitation energy transfer dynamics. We focus on a model that describes a two-level system linearly coupled to a harmonic bath to explore the applicability of quantum correction methods in various parameter conditions. Our results reveal the necessity of applying quantum correction when studying excitation energy transfer dynamics based on results of classical molecular dynamics simula- tion. Our calculations also conclude that the Harmonic method performs the best among the four approaches and that the Prony method has serious draw- backs. The Fitting method provides similar results as the Standard method, and both methods perform well at a higher temperature or in the condition where relaxation is driven by coherent evolution.

The work described in this thesis is directed study toward understanding the structure and function of the pMMO from Methylococcus capsulatus (Bath). A variety of modern techniques have been brought to bear on this problem. An important development has been the development of a hollow-fiber bioreactor and fermentation technology toward scaling up the growth of the methanotropic bacteria. This new technology has allowed the purification of highly active pMMO in membranes, as well as in-depth biochemical/biophysical characterization of the membrane protein after the purification of the highly active pMMO. In order to explore the structure of the active site as well as the nature of the reaction intermediate(s) formed at the active site during turnover of the enzyme, we have subjected the pMMO to different levels of reductants, oxidants and suicide substrate acetylene under dioxygen tensions and looked for change at various stages of oxidation of the copper clusters. Both the catalytic and electron transfer clusters (C- and E-clusters, respectively) have been examined by EPR spectroscopy and X-ray K-edge absorption to distinguish between various multi-oxidation states of the copper clusters. To date, EPR and X-ray absorption measurements have confirmed the classification of the 15 copper ions into 3 trinuclear copper clusters for electron transfer (E-clusters) and 2 trinuclear copper clusters for dioxygen chemistry and alkane hydroxylation (C-clusters). Further purification by membrane solubilization in dodecyl b-D maltoside followed by fractionation of the protein-detergent complexes according to molecular size using gel filtration chromatography yielded the pMMO-detergent complex in good yield and high homogeneity. The purified pMMO-detergent complex has not only been identified by mass finger printing, but also by the determination of the actual molecular mass (99kDa) of the pMMO by MALDI-TOF mass analysis. Finally, ATR-FTIR spectroscopy combined with limited proteolysis has provided the direct evidence for the presence of a-helices in the membrane-embedded domains of pMMO.
