Abstract:
Most adaptive neural control schemes are based on stochastic gradient-descent backpropagation (SGBP), which suffers from local minima problem. Although the recently proposed regularized online sequential-extreme learning machine (ReOS-ELM) can overcome this issue, it requires a batch of representative initial training data to construct a base model before online learning. The initial data is usually difficult to collect in adaptive control applications. Therefore, this paper proposes an improved version of ReOS-ELM, entitled fully online sequential-extreme learning machine (FOS-ELM). While retaining the advantages of ReOS-ELM, FOS-ELM discards the initial training phase, and hence becomes suitable for adaptive control applications. To demonstrate its effectiveness, FOS-ELM was applied to the adaptive control of engine air-fuel ratio based on a simulated engine model. Besides, controller parameters were also analyzed, in which it is found that large hidden node number with small regularization parameter leads to the best performance. A comparison among FOS-ELM and SGBP was also conducted. The result indicates that FOS-ELM achieves better tracking and convergence performance than SGBP, since FOS-ELM tends to learn the unknown engine model globally whereas SGBP tends to “forget” what it has learnt. This implies that FOS-ELM is more preferable for adaptive control applications.

Abstract:
Short-chain fructo-oligosaccharides (FOS) are known to have beneficial effects on health. However, the effects of FOS on insulin resistance have not been fully clarified. We observed the effects of FOS feeding on insulin sensitivity and adipocytokine release from abdominal adipocytes in weaning rats. Male Sprague–Dawley rats, 3 weeks old, were divided into three groups and fed a sucrose-based American Institute of Nutrition (AIN)-93 growth diet (control), the control diet containing 5 % FOS for 5 weeks (FOS-5wk) or the control diet for 2 weeks followed by the 5 % FOS diet for 3 weeks (FOS-3wk). Tail blood was collected after fasting for 9 h on day 33 of feeding, and glucose and insulin levels were measured. On the last day, rats were anaesthetised and killed after the collection of aortic blood. Small- and large-intestinal mesenteric fat tissues were immediately excised, and the release of adiponectin, leptin and TNF-α was evaluated from the subsequently isolated adipocytes. The weight of the large-intestinal mesenteric fat, fasting blood insulin level and homeostatic model assessment for insulin resistance decreased in a time-dependent manner, and were much lower in the FOS-5wk group than in the control group. These values were correlated with aortic blood leptin levels. The secretion rate of leptin from the isolated mesenteric adipocytes in the small intestine, but not in the large intestine, was lower in the FOS-fed groups than in the control group. In conclusion, FOS feeding improved insulin sensitivity accompanied by the reduction in large-intestinal fat mass and leptin secretion from the mesenteric adipocytes of the small intestine.

Abstract:
Many disorders, such as nervous system disorders, can affect orientation of the body segments in 3D space negatively. Patients with these disorders often show body segments instability during stance tasks. Nowadays, 3-axis gyroscopes are about to be used to measure postural stability. The main objective of the paper is to describe a method which would be suitable for quantifying postural stability and 3D movement as a whole using a cheap 3-axis gyroscope. New method based on the volume of a 3D convex hull (CH) obtained by plotting pitch, roll and yaw angles versus each other was proposed for quantitative evaluation of 3D trunk sway. The sway was measured while patients with degenerative cerebellar disorder (Pts) and eleven healthy subjects (HSs) performed quiet stance on a firm surface (FiS) and foam surface (FoS) with open eyes (OE) and closed eyes (CE). The CH was used to identify differences in balance control, and there were significant differences found between the two groups. The median (Mdn) of the volume of Pts with OE on FiS is four times larger than the Mdn of the volume of HS with OE on FiS. The Mdn of the volume of Pts with CE on FoS is 80 times larger than the Mdn of the volume of HS with CE on FoS. It was therefore found that the volume of CH is suitable for quantifying postural sway and identifying differences in balance control.

Abstract:
Striga species cause significant yield loss in maize varying from 20 to 100%. The aim of the present study was to screen and identify maize genotypes with partial resistance to S. hermonthica (Sh) and S. asiatica (Sa) and compatible with Fusarium oxysporum f. sp. strigae (FOS), a biocontrol agent. Fifty-six maize genotypes were evaluated for resistance to Sh and Sa, and FOS compatibility. Results showed that FOS treatment significantly (p < 0.001) enhanced Striga management compared to the untreated control under both Sh and Sa infestations. The mean grain yield was reduced by 19.13% in FOS-untreated genotypes compared with a loss of 13.94% in the same genotypes treated with FOS under Sh infestation. Likewise, under Sa infestation, FOS-treated genotypes had a mean grain yield reduction of 18% while untreated genotypes had a mean loss of 21.4% compared to the control treatment. Overall, based on Striga emergence count, Striga host damage rating, grain yield and FOS compatibility, under Sh and Sa infestations, 23 maize genotypes carrying farmer preferred traits were identified. The genotypes are useful genetic materials in the development of Striga-resistant cultivars in Tanzania and related agro-ecologies.

Abstract:
Interconnecting networks adopting Fast Optical Switches (FOS) can achieve high bandwidth, low latency, and low power consumption. We propose and demonstrate a novel interconnecting topology based on FOS (FOSquare) with distributed fast flow control which is suitable for HPC infrastructures. We also present an Optimized Mapping (OPM) algorithm that maps the most communication-related processes inside a rack. We numerically investigate and compare the network performance of FOSquare with Leaf-Spine under real traffic traces collected by running multiple applications (CG, MG, MILC, and MINI_MD) in an HPC infrastructure. The numerical results show that the FOSquare can reduce >10% latency with respect to Leaf-Spine under the scenario of 16 available cores.

Firstly, necessary and sufficient conditions of H∞ control and state feedback controller design are proposed. Then, robust H∞ control for FOS with uncertainty is studied, and state feedback controller is designed. These conditions are based on linear matrix inequalities (LMI) and can be easily solved by the LMI toolbox. Finally, the effectiveness of these conditions is verified by two numerical examples.

Abstract:
Associations of CRISPLD2 (cysteine-rich secretory protein LCCL domain containing 2) and genes belonging to its activation pathway, including FOS (Fos proto-oncogene), CASP8 (caspase 8) and MMP2 (matrix metalloproteinase 2), with nonsyndromic orofacial cleft risk, have been reported, but the results are yet unclear. The aim of this study was to evaluate single nucleotide polymorphisms (SNPs) in FOS, CASP8 and MMP2 and to determine their SNP-SNP interactions with CRISPLD2 variants in the risk of nonsyndromic cleft lip with or without cleft palate (NSCL±P) in the Brazilian population. The SNPs rs1046117 (FOS), rs3769825 (CASP8) and rs243836 (MMP2) were genotyped using TaqMan allelic discrimination assays in a case-control sample containing 801 NSCL±P patients (233 nonsyndromic cleft lip only (NSCLO) and 568 nonsyndromic cleft lip and palate (NSCLP)) and 881 healthy controls via logistic regression analysis adjusted for the effects of sex and genomic ancestry proportions with a multiple comparison p value set at ≤0.01. SNP-SNP interactions with rs1546124, rs8061351, rs2326398 and rs4783099 in CRISPLD2 were performed with the model-based multifactor dimensionality reduction test complemented with a 1000 permutation-based strategy. Although the association between FOS rs1046117 and risk of NSCL±P reached only nominal p values, NSCLO risk was significantly higher in carriers of the FOS rs1046117 C allele (OR: 1.28, 95% CI: 1.10–1.64, p = 0.004), TC heterozygous genotype (OR: 1.59, 95% CI: 1.16–2.18, p = 0.003), and in the dominant model (OR: 1.50, 95% CI: 1.10–2.02, p = 0.007). Individually, no significant associations between cleft risk and the SNPs in CASP8 and MMP2 were observed. SNP-SNP interactions involving CRISPLD2 variants and rs1046117 (FOS), rs3769825 (CASP8) and rs243836 (MMP2) yielded several significant p values, mostly driven by FOS rs1046117 and CASP8 rs3769825 in NSCL±P, FOS rs1046117 in NSCLO and CRISPLD2 rs8061351 in NSCLP. Our study is the first in the Brazilian population to reveal the association of FOS rs1046117 with NSCLO risk, and to support that CRISPLD2, CASP8, FOS and MMP2 interactions may be related to the pathogenesis of this common craniofacial malformation.

Abstract:
Ketogenic diets (KDs) are a promising alternative therapy for pediatric refractory epilepsy. Several predictors of KD responsiveness have been identified, including biochemical parameters, seizure types, and electroencephalography (EEG) examinations. We hypothesized that graph theory-based EEG functional connectivity could explain KD responses in patients presenting focal onset seizure (FOS). A total of 17 patients aged 0–30 years old with focal onset seizures (FOS) were recruited as a study group between January 2015 and July 2021. Twenty age-matched children presenting headache with no intracranial complications nor other medical issues were enrolled as a control group. Data were obtained at baseline and at 12 months after initiating KD therapy (KDT) using the child behavior checklist (CBCL) and brain functional connectivity parameters based on phase-locking value from 19 scalp EEG signals, including nodal strength, global efficiency, clustering coefficient, and betweenness centrality. Compared with age-matched controls, patients presenting FOS with right or bilateral EEG lateralization presented higher baseline functional connectivity, including parameters such as global efficiency, mean cluster coefficient and mean nodal strength in the delta and beta frequency bands. In patients presenting FOS with right or bilateral EEG lateralization, the global efficiency of functional connectivity parameters in the delta and theta frequency bands was significantly lower at 12 months after KDT treatment than before KDT. Those patients also presented a significantly lower mean clustering coefficient and mean nodal strength in the theta frequency band at 12 months after KDT treatment. Changes in brain functional connectivity were positively correlated with social problems, attention, and behavioral scores based on CBCL assessments completed by parents. This study provides evidence that KDT might be beneficial in the treatment of patients with FOS. Graph theoretic analysis revealed that the observed effects were related to decreased functional connectivity, particularly in terms of global efficiency. Our findings related to brain connectivity revealed lateralization to the right (non-dominant) hemisphere; however, we were unable to define the underlying mechanism. Our data revealed that in addition to altered brain connectivity, KDT improved the patient’s behavior and emotional state.

Abstract:
Abstract The problem of measuring road vehicle’s weight-in-motion (WIM) is important for overload enforcement, road maintenance planning and cargo fleet managing, control of the legal use of the transport infrastructure, road surface protection from the early destruction and for the safety on the roads. The fibre-optic sensors (FOS) functionality is based on the changes in the parameters of the optical signal due to the deformation of the optical fibre under the weight of the crossing vehicle. A fibre-optic sensor responds to the deformation, therefore for WIM measurements it is necessary to estimate the impact area of a wheel on the working surface of the sensor called tyre footprint. This information is used further for the estimation of the vehicle wheel’s speed, contact width, length, and, finally, axle’s weight while in motion. Recorded signals from a truck passing over a group of FOS with various speeds and known weight are used as an input data. The results of the several laboratory and field experiments with FOS, e.g. load characteristics according to the temperature, contact surface width and loading speed impact, are provided here. The method of initial signal deconvolution on symmetric and asymmetric components provides the chance to approximate geometric size of tyre surface footprint as well as calculate weight on each wheel separately. The examples of the estimation of a truck speed, tyre contact surface footprint parameters using FOS signals are discussed in this article.

Copur, Engin H. "Repetitive control for FES-based tremor suppression." Thesis, University of Southampton, 2017. https://eprints.soton.ac.uk/419405/.

Full text
Abstract:
Tremor is an involuntary, rhythmic movement of one or more body parts which prevents patients from performing activities of daily living (ADL), thereby greatly diminishing quality of life. Although there are various methods to suppress tremor, each is limited by either cost, ability to produce sufficient tremor suppression (TS) or interference with voluntary action. Functional electrical stimulation (FES) has attracted significant research attention as a novel approach for TS, and has substantial potential advantage in terms of cost, convenience and size. Results from previous studies have demonstrated that FES controlled by classical control methods is unable to produce satisfactory TS, while also producing intense interference with voluntary action. Thus their performance is inherently limited by the drawbacks of conventional feedback design. Since repetitive control (RC) is able to reject a periodic disturbance completely and tremor can be regarded as a periodic disturbance, RC may have more potential for TS than other classical feedback control techniques. This thesis thus provides the first thorough implementation and assessment of RC for TS by means of FES in order to establish its feasibility and performance advantages compared to the conventional filter techniques (FT) that have so far been employed. Due to the importance of the wrist joint in ADL, wrist movement in flexion/extension is targeted within this programme of research. First, simulations are performed using a previously validated linear model of tremulous wrist dynamics to evaluate the feasibility of applying linear RC for TS, and results show that RC is able to produce complete tremor suppression but incurs a severe interference with voluntary action. Since this linear model does not account for the critical properties of the dynamics and RC requires a reliable knowledge of the plant dynamics to guarantee the stability of RC and improve its performance, this thesis then proposes a nonlinear model structure with an identification procedure that maintains the balance between the accuracy and the needs of the clinical domain. Then a linearising control approach is undertaken to enable linear RC design and a mechanism is proposed to preserve the voluntary action which is restricted by applying RC. Analysis confirms that the proposed mechanism can significantly reduce the undesirable interference of RC with voluntary action. Finally, two separate experimental studies are conducted using a test platform. The former is performed to fix the order of the model components in advance to reduce the computational effort of the identification procedure. The response of the wrist joint to FES signals applied to the flexion/extension muscles of each participant is collected. Using these input/output data sets, different models are identified for a number of different orders. Then the fitting accuracies of all models with the same order are averaged and an order is selected with maintaining the balance between model accuracy and simplicity. The second experimental study is to confirm the higher potential of the proposed RC compared with FT for FES-based TS. A mechanical system is introduced to the existing test platform to induce tremor artificially since the participants are unimpaired. The participants are asked to complete three consecutive tests to examine the effect of induced tremor on the ability of patients to perform voluntary task, the capability of FES to suppress the induced tremor and the effect of FES on the voluntary motion. The results indicate that the proposed RC approach with the developed model identification procedure can suppress tremor more effectively than FT and leads to a minimal interference with voluntary motion. This research therefore has established the feasibility of RC for TS by validating the model accuracy, the identification procedure, and the control performance. It has therefore potential for future exploration to provide more effective solutions for patients.

Abstract:
In the recent years we have seen that internet connectivity has multiplied vastly and that more and more computation and information storage are moved to the cloud. Similarly to other types of networks, industrial systems also see an increase in the number of communicating devices. Introduction of wireless communication into industrial systems instead of currently used wired networks will allow interconnection of all kinds of stationary and mobile machinery, robots and sensors and thereby bring multiple benefits. Moreover, recent developments in cloud and fog computing open many new opportunities in control, analysis and maintenance of industrial systems. Wireless systems are easy to install and maintain and relocation of data analysis and control services from local controllers to the cloud can make possible computations requiring a lot of resources, improve efficiency of collaboration between different parts of a plant or several plans as cloud servers will be able to store information and be accessible from all of them. However, even though introduction of wireless communication and cloud services brings a lot of benefits, new challenges in fulfilling industrial requirements arise as, e.g., packet delivery rates might be affected by disturbances introduced in wireless channels, data storage on distant servers might introduce timing and security issues, resource allocation and reservation for controllers supervising multiple processes should be considered to provide real-time services. The main goal of this thesis work is to consider design possibilities for a factory including local and cloud controllers, i.e. look at how the work of the factory should be organized, where control decisions should be made, analyze pros and cons of making the decisions at local (fog) and cloud servers. To narrow down the problem, an example factory with who independent wireless networks (each consisting of one sensor, one actuator and one local control node) and a cloud controller controlling both of them will be considered. Selected structure allows all the questions of interest to be considered, while its prototype can be built using available for this thesis work equipment

Abstract:

A major feature of the human eye is the compressed sensitiveness of the retina. An image coder, which makes use of this, can heavily encode the parts of the image which is not close to the focus of our eyes. Existing image coding schemes require that the gaze direction of the viewer is measured. However, a great advantage would be if an estimator predicts the focus of attention (FOA) regions in the image.

This report presents such an implementation, which is based on a model that mimics many of the biological features of the human visual system (HVS). For example, it uses a center-surround mechanism, which is a replica of the receptive fields of the neurons in the HVS.

An extra feature of the implementation is the extension to handle video sequences, and the expansion of the FOA:s. The test results of the system show good results from a large variety of images.

Abstract:
Functional electrical stimulation (FES) is a well-established approach that is employed as a therapeutic tool for the restoration of motor control in individuals experiencing muscle impairment. Although its use as a rehabilitation tool is validated by clinical results, current control approaches limit the full exploitation of its potential due to the lack of accuracy with which the FES is applied. Research has thus focused on the use of advanced, closed-loop control algorithms to provide more accurate FES that is both task-oriented, and matches the rehabilitation needs of the patient. Experimental results have been reported for a variety of control schemes. However, the majority of approaches have failed to transfer to clinical practice due to the difficulties associated with identifying a model of electrically stimulated muscle that adapts as the true plant varies with time. Estimation-based multiple model switched adaptive control (EMMSAC) is a robust control approach that has the potential to overcome the problems associated with the uncertain, time-varying properties of electrically stimulated muscle. EMMSAC utilises optimal disturbance estimation to assess the respective performances of a set of candidate plant models. Then the controller associated with the model that has best performance is switched into closed-loop operation. This thesis details the algorithmic modifications that allow disturbance estimation to be performed in the time-varying setting for nonlinear Hammerstein structures. Then it is shown experimentally that a general plant model set can be identified that represents the time-varying, FES-induced muscle activation dynamics for the population of younger healthy adults. This finding is exploited to design an EMMSAC controller that achieves accurate trajectory tracking for multiple participants with minimal prior model identification. Results indicate that the use of EMMSAC reduces RMS tracking error when compared with a fixed controller; similar results are also reported for older healthy participants. Furthermore, initial results for a small sample of stroke-participants are shown, which confirms the potential for the proposed control approach to be applied in a clinical setting for FES-based rehabilitation.

It is important for companies to manage their revenues and -reduce their costs efficiently. These goals can be achieved through effective pricing and inventory control strategies. This thesis studies a joint multi-period pricing and inventory control problem for a make-to-stock manufacturing system. Multiple products are produced under shared production capacity over a finite time horizon. The demand for each product is a function of the prices and no back orders are allowed. Inventory and production costs are linear functions of the levels of inventory and production, respectively. In this thesis, we introduce an iterative gradient-based algorithm. A key idea is that given a demand realization, the cost minimization part of the problem becomes a linear transportation problem. Given this idea, if we knew the optimal demand, we could solve the production problem efficiently. At each iteration of the algorithm, given a demand vector we solve a linear transportation problem and use its dual variables in order to solve a quadratic optimization problem that optimizes the revenue part and generates a new pricing policy. We illustrate computationally that this algorithm obtains the optimal production and pricing policy over the finite time horizon efficiently. The computational experiments in this thesis use a wide range of simulated data. The results show that the algorithm we study in this thesis indeed computes the optimal solution for the joint pricing and inventory control problem and is efficient as compared to solving a reformulation of the problem directly using commercial software. The algorithm proposed in this thesis solves large scale problems and can handle a wide range of nonlinear demand functions.

Mestrado em Biotecnologia Alimentar
O desenvolvimento de novos produtos é atualmente uma forte aposta das empresas na busca de envolver novos eixos e nichos de mercado, através da inovação, capaz de promover produtos adequados às necessidades mais eminentes do mercado alvo. O projeto em questão, teve lugar no seio do Grupo Derovo, com o objetivo fundamental de desenvolvimento de um ovoproduto líquido pasteurizado à base de gema de ovo (ingrediente crucial e maioritário) específico para a produção de fios de ovos, cuja adequação pode ser em produtos profissionais industriais, bem como para um consumidor doméstico, pautando-se por ser um produto de fácil utilização e capaz de produzir um resultado de alta qualidade. Tratando-se de um projeto ligado ao desenvolvimento de um novo produto alimentar, este processo contemplou diversas etapas, entre as quais se destacam essencialmente: perceção/compreensão das necessidades inerentes ao mercado; ensaios preliminares; testes de formulação de protótipos e avaliação da sua performance; análise de mercado de protótipos selecionados. Numa primeira fase, realizaram-se alguns ensaios preliminares com o intuito de perceber qual o efeito de diversas etapas do ciclo produtivo da unidade produtiva em questão, acompanhados pela análise de parâmetros físico-químicos (pH; Teor de Sólidos Solúveis (°Brix); Viscosidade (mPa.s); Extrato Seco (%)) e da análise fotográfica. Demonstrou-se efetivamente que a gema de ovo não pasteurizada apresentou resultados notoriamente superiores aos conseguidos com as restantes tipologias estudadas. Após uma procura de agentes tecnológicas no mercado de ingredientes alimentares, iniciou-se a fase de formulação de diversos protótipos, por adição de diversas percentagens (0,1 a 0,03%) e combinações (agentes emulsionantes e/ou agentes texturizantes) tendo posteriormente realizado as análises físico-químicas já referenciadas (incluindo ainda Atividade da água e cor). Seguiu-se a avaliação dos protótipos em desenvolvimento na produção de fios de ovos, através de um controlo de diversos fatores inerentes à sua produção (temperatura da calda de açúcar, entre outros), tendo os resultados finais sido alvo de uma análise fotográfica, análise sensorial (provas de medição do grau de satisfação) e análise microbiológica, com o objetivo de comparar os diversos ensaios e auxiliar na selecção dos protótipos em estudo. Demonstrou-se que a percentagem de 0,03% teve a melhor performance na produção de um fio de ovo com características adequadas, principalmente por aplicação de dois agentes tecnológicos específicos (Jungbunzlauer e DynaVisc), estando igualmente adequada à qualidade exigida pelo mercado.
Development of new food products is currently a strong focus of the companies involved in the search for new ways and niche markets through innovation to promote adequate products to the most eminent needs of our market. This project, developed at the Group Derovo, had as its main objective the development of new egg product mainly constituted by pasteurized liquid egg yolk (crucial and major ingredient) specific for the production of traditional portuguese sweet – “fios de ovos” - to both professionals industrials, and also the household consumer, guided for being a product easy to use and capable of producing a high quality product. Since this is a project linked to the development of a new food product, this process included several steps, among which are important to highlight: understanding of the needs inherent in the market; preliminary tests; formulation testing of prototypes and their evaluation performance; market analysis of selected prototypes. Initially, there were some preliminary tests in order to see what effect various stages of the production cycle of egg production unit in question, followed by analysis of physico-chemical parameters (pH, Total Soluble Solids (°Brix), Viscosity (mPa.s), Dry Matter (%)) and photographic analysis. It was shown that effectively unpasteurized egg yolk was notably greater to the results achieved with other types studied. After a demand on the market of technological agents of food ingredients, several prototypes were formulated by addition of various percentages (0,1 to 0,03%) and combinations (emulsifying agents and/or texturizing agents) and subsequently analyzed from the standpoint of the physicochemical analyses already mentioned (further including Water Activity and color) and the microbiological point of view. This was followed by evaluation of the prototype under development in the production of traditional portuguese sweet – “fios de ovos” - by controlling several factors inherent in their production (temperature sugar syrup, etc.), and the final result was the target of a photographic analysis, sensory analysis (tests measuring the degree of satisfaction) and microbiological analysis in order to compare the different assays as well as aid in the selection of the prototypes in this study. It was demonstrated that the proportion of 0.03% had the better performance in the production of traditional portuguese sweet with suitable characteristics mainly by application of two specific technological agents (Jungbunzlauer e DynaVisc) and is also according to the evaluation made by the market.

Abstract:
This work is part of ongoing research conducted at Virginia Commonwealth University relating to unmanned aerial vehicles. The primary objective of this thesis was to develop a flexible, high-performance autopilot platform in order to facilitate research on advanced flight control algorithms. A dual FPGA-based system architecture utilizing a stacked, multi-board design was created to meet this goal. Processing tasks were split between the two FPGA devices, allowing for improved system timing and increased throughput. A combination of analog and digital filtering techniques were employed in the new system, resulting in enhanced sensor accuracy and precision compared to the previous generation autopilot system. Several important improvements to the safety and reliability of the overall system were also achieved.

Abstract:
The textbook reveals the concept and meaning of digital technologies, the legal nature of information interaction in the implementation of control measures based on general theoretical concepts and regulatory legal acts. Special attention is paid to the types of information systems used in the control process in the financial and budgetary sphere. The necessity of creating information systems based on international experience, global indices and rules of the Organization for Economic Cooperation and Development (OECD) is justified. The article defines the specific characteristics of the state information systems used in the control (monitoring) in the financial and budgetary sphere, and also considers the subsystems that make up the state integrated information system "Electronic Budget" and other information systems in the information space of the Russian Federation. The article analyzes interdepartmental information interaction and digital methods that ensure the protection of information in the course of financial control. For graduate students, postgraduates and teachers of law and non-legal universities, as well as for practitioners.
