Abstract:

Purpose – Model order reduction (MOR) has been widely used in the electric networks but little has been done to reduce higher index differential algebraic equations (DAEs). The paper aims to discuss these issues. Design/methodology/approach – Most methods first do an index reduction before reducing a higher DAE but this can lead to a loss of physical properties of the system. Findings – The paper presents a MOR method for DAEs called the index-aware MOR (IMOR) which can reduce a DAE while preserving its physical properties such as the index. The feasibility of this method is tested on real-life electric networks. Originality/value – MOR has been widely used to reduce large systems from electric networks but little has been done to reduce higher index DAEs. Most methods first do an index reduction before reducing a large system of DAEs but this can lead to a loss of physical properties of the system. The paper presents a MOR method for DAEs called the IMOR which can reduce a DAE while preserving its physical properties such as the index. The feasibility of this method is tested on real-life electric networks.

Abstract:

Aromatic extracts (AEs; distillate AEs [DAEs] and residual AEs [RAEs]) are complex, highly viscous liquid petroleum streams with variable compositions derived by extraction of aromatic compounds from distillate and residual petroleum fractions from a vacuum distillation tower, respectively. The DAEs generally contain significant amounts of polycyclic aromatic compounds (PACs) and are carcinogenic. The RAEs typically contain lower concentrations of biologically active PACs. The PACs in refinery streams can cause effects in repeated-dose and developmental toxicity studies. In a 13-week dermal study, light paraffinic DAE had several dose-related effects involving multiple organs; no-observed-effect level was <5 mg/kg/d, with no overt toxicity. Predicted dose-responses at 10% (PDR10s), modeled doses causing a 10% effect on sensitive end points based on PAC content, ranged from 25 to 78 mg/kg/d for untested paraffinic DAEs. The no observed adverse effect level (NOAEL) for developmental toxicity for light paraffinic DAE was 5 mg/kg/d. Statistically significant developmental effects at higher doses were associated with maternal effects. The PDR10s for developmental toxicity of paraffinic DAEs ranged from 7 to >2000 mg/kg/d, reflecting differences due to variation in PACs. The NOAELs for RAEs were 500 mg/kg for 90-day studies and 2000 mg/kg for developmental toxicity. Reproductive toxicity is not considered to be a sensitive end point for AEs based on the toxicity tests with DAEs, RAEs, and other PAC-containing petroleum substances. In vivo micronucleus tests on heavy paraffinic DAE, RAEs, and a range of other petroleum substances have been negative. The exception to this general trend was a marginally positive response with light paraffinic DAE. Most DAEs are considered unlikely to produce chromosomal effects in vivo.

Abstract:

3049 Background: Owing to its high efficacy and tolerability, brentuximab vedotin (BV) is increasingly being favored over other aggressive systemic therapies for the treatment of various CD30+ Hodgkin and non-Hodgkin lymphomas, including peripheral T-cell lymphoma and cutaneous T-cell lymphomas. Dermatologic adverse events (dAE) are one of the most common toxicities associated with BV but data regarding their characteristics including correlation to dose, time to occurrence, and management is scarce. We aim to describe the clinical and pathologic characteristics of dAEs associated with BV, their relationship with administered dose regimen, and available management strategies. Methods: An IRB-approved retrospective analysis was conducted for all patients who had received at least one cycle of BV from Memorial Sloan Kettering Cancer Center in 2009-2020. Logistic regression, χ2, student’s t-test were performed for univariate analyses. Kaplan-Meier survival and multivariate Cox proportional hazard model evaluated dAE occurrence stratified by 5 major dose regimens (single cycle, 1.2mg q1w, 1.2mg q2w, 1.2mg q3w, 1.8mg q3w). Results: Of 611 patients, 201 experienced dAE with median time-to-event of 24 days and 29% experiencing > 1 dAEs. Rash was the most common (62%; 142/230), followed by alopecia (20%) and xerosis (13%). For rash, 50% reported involvement of only the extremities and/or acral sites compared to 25% who had generalized rash. Of those reported (111), 68 patients had grade 1 dAE (61%), 38 grade 2 (34%), and 5 grade 3 (5%)-all grade 3 were rash (maculopapular/morbilliform). 14 cases (7%) resulted in treatment interruptions and 6 in discontinuations due to dAEs (3%). Pathology were often nonspecific consistent with a hypersensitivity reaction: spongiotic/psoriasiform dermatitis with perivascular lymphocytic infiltrates . Patients undergoing weekly regimen were at a statistically and clinically significantly higher risk of dAE during the first 100 days of BV treatment (p = 0.001). Between the two most frequently administered dose regimens (1.8mg vs. 1.2mg, q3w), the higher dose carried 105% higher risk for dAE (HR: 2.047, p = 0.053). Those who had received a single cycle of BV had the lowest risk compared to all other regimen (1/42, p = 0.001). Topical and/or systemic steroids were most frequently prescribed (43%) with 12% of patients requiring systemic steroids. Other treatments varied ranging from antihistamines to moisturizers. Conclusions: Understanding of the detailed characteristics, management strategies, dose-dependent effects associated with BV is critical to provide clinical guidance for primary providers and minimize treatment interruptions or discontinuations. The results overall suggest that the risk for dAEs is dose-dependent with those undergoing frequent dosing regimens having a greater risk, although most dAEs remain mild or low-grade.

Abstract:

n this note, we single out some promising classes of differential-algebraic equations (DAEs) with hysteresis phenomena, and propose their meaningful generalizations. We consider D Es of index 2 having two features: i) non-linearity of hysteresis type modeled by a sweeping process, and ii) impulsive control represented by a bounded signed Borel measure. For such a DAE we design an equivalent structural form, based on the Kronecker-Weierstrass transformation, and prove a necessary and sufficient condition for the existence and uniqueness of a solution to an initial value problem. We propose a notion of generalized solution to a DAE as a realization of impulsive trajectory relaxation. This relaxation is described by a dynamical system with states of bounded variation and can be equivalently represented as a system of “ordinary” DAEs.

Abstract:

Main RecommendationsThe European Society of Gastrointestinal Endoscopy (ESGE) has recognized the need to formalize training in small-bowel endoscopy across European centers. The following criteria and framework for training in small-bowel capsule endoscopy (SBCE) and device-assisted enteroscopy (DAE), which aim to provide uniform and high quality training to ensure that small-bowel endoscopists are competent to operate independently, are based on the current literature and experience of experts in the field. Three main areas are covered: skills required prior to commencing training in small-bowel endoscopy; structured training for trainees to become independent endoscopists; and ways of ensuring competence is achieved. 1 Centers providing training in SBCE should perform a minimum of 75 – 100 SBCEs/year. 2 Experience in bidirectional endoscopies is desirable for structured training in SBCE. 3 SBCE courses should consist of at least 50 % hands-on training and cover information on technology, indications and contraindications for SBCE, pathologies that can be encountered on SBCE, and standard terminology that should be used during reporting of SBCE. An SBCE course should be completed prior to achieving competence in SBCE reporting. 4 Competence in SBCE can be assessed by considering a minimum of 30 SBCEs. Direct Observation of Procedural Skills, short SBCE videos, and multiple-choice questions can be useful to assess improvement in the skills of trainees. 5 Centers offering training in DAE should aim to carry out at least 75 DAEs/year, should have direct links with an SBCE service, and should allow regular discussion of cases at a radiology small-bowel MDT. Training centers with lower numbers are encouraged to offer training by “buddying-up” with other centers, or using mentoring systems. 6 DAE trainees must be independent in bidirectional endoscopies and have experience in level 1 polypectomy prior to commencement of training. They should also be competent in reviewing SBCEs. 7 Training in DAE should be structured with a minimum of 75 procedures, including 35 retrograde DAEs, with therapeutic procedures undertaken in at least 50 % of the DAEs performed. Training should cover the indications, contraindications, complications including prevention, and technicalities of the DAE procedure; formal evaluation should follow. DAE trainees must acquire skills to independently manage and advise on small-bowel pathology following DAE procedures. 8 It is highly recommended that international societies develop online modules and courses on DAE, which are currently lacking across Europe.

Abstract:

This paper is concerned with the study of pseudospectral discretizations of the differential-algebraic equations (DAEs). Pseudospectral method based on Chebyshev polynomials are used to transcribe a given DAE into a system of algebraic equations. A posteriori error bound between the desired solution to the index 2, DAEs and the pseudospectral approximate solution of the problem is estimated in the weighted L2 norm. Some numerical experiments are considered to demonstrate the efficiency and the applicability of the method.

Abstract:

This article (Funded by EPSRC and the National Grid Company.) explores some introductory principles of differential-algebraic equations (DAEs) and makes a connection with the theory of dynamical systems. Some results which are new in the field of DAEs are also surveyed. Most treatments on DAE emphasize the differences that exist when compared with the ODE case. Here we seek to underline the similarities so that readers with a very basic knowledge of nonlinear dynamics can understand some of their consequences in this more general context.

Abstract:

In this article, an optimization task with nonlinear differential-algebraic equations (DAEs) is considered. As a main result, a new solution procedure is designed. The computational procedure represents the sequential optimization approach. The proposed algorithm is based on a multiple shooting parametrization method. Two main aspects of a generalized parametrization approach are analyzed in detail: a control function and DAE model parametrization. A comparison between the original and modified DAEs is made. The new algorithm is applied to solve an optimization task in heat and mass transfer engineering.

In this paper, bifurcation of solution of guasilinear dierential-algebraic equations (DAEs) is studied. Whereas basic principle that quasilinear DAE is eventually reducible to an ordinary dierential equation (ODEs) and that this reduction so we can apply the classical bifurcation theory of the (ODEs). The taylor expansion applied to the reduced DAEs to prove that is equivalent to an ODE which is a normal form under some non-degeneracy conditions theorems given in this work deal with the saddle node,transcritical and pitchfork bifurcation with two-parameters. Some illustrated examples are given to explain the idea of the paper.

Abstract:

INTRODUÇÃO: Há controvérsias se drogas antiepilépticas (DAEs) genéricas são intercambiáveis com as de referência, assim como com as similares com respeito a eficácia e efeitos adversos. Este fato é de fundamental importância e ainda mais relevante em países em desenvolvimento com limitações orçamentárias na área de saúde. MÉTODOS: Após aprovação de Comitê de Ética a Associação Brasileira de Epilepsia aplicou um questionário a pessoas com epilepsia (PCE) com 18 questões de múltipla escolha: quatro relacionadas a dados sócio-demográficos e 14 sobre o conhecimento das formulações de DAEs (de referência, genéricas e similares) e da evidência de mudanças clínicas durante a troca (Teste exato de Fisher, significância 05%). RESULTADOS: 731 PCE de seis Hospitais do Sistema Público participaram, sendo que 91% eram de classes sócio-econômicas média e baixas; das PCE maiores de 18 anos, 24,4% tinha menos de 4 anos de escolaridade, 24,4% entre 5 a 8, 45,6 % tinha pelo menos 9 anos de estudo; 63% recebia mais de uma DAE (53,3% carbamazepina, 26,3% valproato de sódio); 58,1% obtinha as DAEs de órgãos públicos e 21,2% somente em farmácias privadas. Das 731 PCE consultadas, 60,6% não conhecia as diferentes formulações de DAEs (PCE com maior escolarização responderam mais corretamente, p<0.001); somente 36% sabia que a primeira DAE é a referência (maior escolarização, p<0.001); e 10% considerou genéricos "medicações oficiais do governo". Após serem instruídos sobre as formulações de DAEs, 24,7% não sabia que genéricos são mais baratos do que as medicações de referência, 32,5% considerou sua qualidade pior e somente 30% sabia os detalhes de sua embalagem (classes de maior renda, p=0.004). Durante o último ano, 25,6% receberam diferentes formulações de DAEs (especialmente carbamazepina e valproato de sódio) e 14,5% (especialmente com menor escolarização, p<0.001) referiram crises adicionais após a troca (carbamazepina, valproato de sódio e lamotrigina) e 12,2%, aumento de eventos adversos (carbamazepina, valproato de sódio e topiramato). CONCLUSÕES: O conhecimento de diferentes formulações foi pequena entre as PCE entrevistadas, e o recebimento de diferentes formulações de DAEs foi freqüente. Foi referido aparecimento de crises por 14,5% dos pacientes, principalmente naqueles de menor escolaridade, e ainda, aumento de efeitos adversos por ocasião das trocas (por 12,2%). Este fato deve alertar especialistas, sobretudo em países em desenvolvimento que DAEs devem ser consideradas um grupo especial em relação a políticas públicas de medicações genéricas e similares.

Abstract:

Diese Arbeit befasst sich mit Differential-algebraischen Gleichungen (DAEs). DAEs spielen eine wichtige Rolle in der Modellierung, der Simulation und der Optimierung von Netzwerken und gekoppelten Problemen in vielen Anwendungsgebieten. Es werden in Bezug auf die Modellierung und die numerische Simulation von DAEs bereits bestehende Ergebnisse diskutiert und erweitert. Des Weiteren wird die globale eindeutige Lösbarkeit und die Sensitivität der Lösungen mit Hinsicht auf Störungen der DAEs untersucht. Häufig wird die Modellierung von multiphysikalischen Anwendungen durch die Kopplung mehrerer einzelner DAE Systeme realisiert. Diese Herangehensweise kann hochdimensionale DAEs erzeugen, welche aufgrund von Instabilitäten nicht von klassischen numerischen Methoden, simuliert werden können. Angesichts dieser Herausforderungen werden drei Ziele formuliert: Erstens wird ein globales Lösungstheorem formuliert und bewiesen, welches auf gekoppelte Systeme angewandt werden kann, um deren Kopplungsansatz mathematisch zu rechtfertigen. Zweitens werden numerische Methoden vorgestellt, welche unter wesentlich schwächeren Strukturannahmen stabil sind und sich daher für die Simulation von gekoppelten Systemen eignen. Drittens wird eine Strategie präsentiert, die es ermöglicht, explizite Methoden auf gekoppelte Systeme anzuwenden. Um diese Ziele zu erreichen, braucht man ein Entkopplungsverfahren für DAEs, welches die folgenden drei Eigenschaften erfüllt: Die Komplexität des Entkopplungsverfahrens sollte nicht die Komplexität der DAE überschreiten. Das Entkopplungsverfahren sollte Eigenschaften wie Symmetrie, Monotonie und positive Definitheit erhalten. Das Entkopplungsverfahren sollte durch einen Schritt-für-Schritt Ansatz mit unabhängigen Schritten realisiert werden. Sowohl das Konzept des Tractability Index als auch das des Strangeness Index liefert kein solches Entkopplungsverfahren. Daher wird hier ein neues Index Konzept eingeführt, das diesen Anforderungen entspricht.
This thesis addresses differential-algebraic equations (DAEs). They play an important role in the modeling, simulation and optimization of networks and coupled problems in various applications. The main application in this thesis are coupled problems in electric circuit simulation. We discuss and extend existing results regarding the modeling and numerical simulation of DAEs. Furthermore, we investigate the global unique solvability and the sensitivity of solutions with respect to perturbations of DAEs. Nowadays the modeling of multi-physical applications is often realized by coupling systems of DAEs together with the help of additional coupling terms. This approach may yield high dimensional DAEs which cannot be simulated, due to instabilities, by standard numerical methods. Regarding these challenges we formulate three objectives: First we provide a global solvability theorem which can be applied to coupled systems to mathematically justify their coupling approach. Second we introduce numerical methods which are stable without needing any structural assumptions. Third we provide a way to apply explicit methods to coupled systems to be able to handle the size of the coupled systems by parallelizing the algorithms. To achieve these objectives, we need a decoupling procedure which fulfills the following three properties: The complexity of the decoupling procedure has to reflect the complexity of the DAE, i.e. the decoupling procedure should be state-independent if possible. The decoupling procedure should preserve properties like symmetry, monotonicity and positive definiteness. The decoupling procedure should be realized by a step-by-step approach with independent stages. Both the Tractability Index concept and the Strangeness Index concept do not provide such a decoupling procedure. For this reason we introduce a new index concept which provides such a decoupling procedure.

Abstract:

Many methods have been proposed for the stabilization of higher index differential-algebraic equations (DAEs). Such methods often involve constraint differentiation and problem stabilization, thus obtaining a stabilized index reduction. A popular method is Baumgarte stabilization, but the choice of parameters to make it robust is unclear in practice. Here we explain why the Baumgarte method may run into trouble. We then show how to improve it. We further develop a unifying theory for stabilization methods which includes many of the various techniques proposed in the literature. Our approach is to (i) consider stabilization of ODEs with invariants, (ii) discretize the stabilizing term in a simple way, generally different from the ODE discretization, and (iii) use orthogonal projections whenever possible. The best methods thus obtained are related to methods of coordinate projection. We discuss them and make concrete algorithmic suggestions.

Este trabalho apresenta uma proposta metodológica para um diagnóstico ambiental em estabelecimentos de saúde, visando, com ênfase nos critérios de gerenciamento ambiental, identificar os pontos positivos e negativos do manejo de resíduos de serviços de saúde dos estabelecimentos, a fim de poder propor ações de melhorias no desempenho ambiental dos mesmos. O modelo Diagnóstico Ambiental em Estabelecimentos de Saúde # DAES, proposto, tem como fundamentação teórica, para a elaboração de seus critérios, a legislação vigente sobre o manejo e disposição final de resíduos de serviços de saúde (RSS), constantes nas Resoluções da Agência de Vigilância Sanitária e Conselho Nacional de Meio Ambiente (RDC 33/03 e, 5/93 e 283/01, respectivamente), contando ainda, com as disposições das Normas da Associação Brasileira de Normas Técnicas (ABNT) sobre o assunto. O gerenciamento das rotinas e procedimentos dos estabelecimentos, com base nestas legislações, permite administrar as relações entre as atividades do estabelecimento e o meio ambiente. Assim, buscando validar o modelo proposto, aplicou-se, o mesmo, em 26 estabelecimentos de saúde de Santa Catarina, o que produziu um diagnóstico ambiental do setor. Com base no modelo aplicado foi possível constatar que a ferramenta é de fácil aplicação e análise, além de poder ser considerada uma ferramenta de sensibilização para a administração, quanto a necessidade de melhoras no gerenciamento ambiental do estabelecimento, mostrando-se adequada para uma avaliação inicial do desempenho ambiental do mesmo.

Abstract:

AbstractThermal decomposition kinetics of Polypropylene (PP) waste is extremely important with respect to valorisation of waste plastics and production of utilizable components viz. chemicals, fuel oil & gas. The present research study focuses on pyrolysis kinetics of PP waste, which is present as a fraction of municipal plastic waste through distributed activation energy model (DAEM). The decomposition kinetics for PP follows a Gaussian distribution, where the normal distribution curves were centred corresponding to activation energy of 224 kJ/mol. The standard deviation of the distribution for the PP sample was found to be 22 kJ/mol indicating its wider distribution of decomposition range. The data validation has been carried out by comparing the rate parameter and extent of conversion values calculated through DAEM model with the Thermogravimetric analysis (TGA) experiments carried out for PP at various heating rates of 5, 10, 20 and 40 °C/min.

Abstract:

With the strategy “Automatically Reduce Natural-Coordinate DAEs Assembled Automatically” in mind, the authors have developed a new reduction method on natural-coordinate constant constraint (NCCC). A NCCC constrains a state variable to a constant, leading to a simplest constraint equation which often appears in the joints which connect elements defined with natural coordinates to the ground. The new reduction method can be performed once for every NCCC, with the result that one column and one row are removed from the system mass matrix. The new reduction operation can be used independently and repeatedly, a characteristic suitable for computer implementation. For the purposes of illustration, after a double-wishbone suspension is modeled with 48 natural coordinates and 12 NCCCs, its DAE is reduced by the new reduction method, with 36 natural coordinates remaining.

Abstract:

The primary goal of this research was to identify the role of non-linear parameter estimation in clutch torque estimation for automotive applications. The benefit of this approach in estimating parameters of a system defined by a set of differential algebraic equations (DAEs) that represents, say, clutch torque profile is investigated. In addition, online implementation, albeit at a slow rate compared to control loop rates is demonstrated. This method of analytical DAE based estimation has significant advantages over purely empirical methods in that it directly identifies the relationships between system problem variables, such as, engine speed, cross shaft angle to variable of interest, say, clutch torque, unlike, indirect approaches [1]. In addition, in contrast with time series evolution of discrete system models based on ARMAX models, this approach allows a designer to know the relationship between system parameters such as friction coefficient, clutch engagement angle, etc and the estimation process leading to better design of clutch control algorithms. However, unlike, the direct digital control methods, DAE based approaches are computationally more intensive resulting in a need for additional onboard processing. One of the goals of this initial research is to study this to identify practical analytical and numerical approaches that will lead to onboard implementation of these algorithms for truck applications, specifically in automated mechanical transmissions (AMTs) [2, 3].

Abstract:

Dynamics software usage in the analysis of vehicles is becoming more prevalent in industrial settings. Multibody tools allow the user to put together a digital or virtual model of the vehicle before any physical prototype is built. The tools have now reached a level of sophistication that allows the same tests to be performed on the digital model as on the physical model. In the analysis of a vehicle a virtual model allows the user to analyze the vehicle’s performance in ride and comfort scenarios as well as in durability scenarios. Multibody tools also allow the user to perform design of experiments or trade-off studies in these scenarios by varying different parameters of the vehicle. However, to be of optimal usage in a design of experiments approach the solution times of the complex models must be short allowing larger parameter studies to be done quickly. In the analysis of many vehicles and in particular race cars only the vehicle’s limits in a turn or corner are needed. Limiting the vehicle analysis to cornering allows the multibody code to use steady-state analysis instead of a full dynamic simulation. Typically, multibody codes construct differential-algebraic equations (DAE) to form the equations of motion and then must use complex numerical analysis techniques to solve the DAEs. By making the assumption that the vehicle is in a corner the DAEs can be reduced to a set of algebraic equations, which can then be solved very efficiently by a statics solver. A statics solver by definition requires the velocities and accelerations to be zero, but in the cornering analysis of a vehicle this assumption can not be made. This paper will document the extensions necessary to convert the Virtual.Lab multibody statics solver into a steady-state solver it will then apply this steady-state solver to the cornering analysis of a full vehicle model.

Abstract:

Recent legislation of engine exhaust Particulate Matter (PM) emission levels cannot be met with in-cylinder PM reduction techniques, thus resulting in the need for a Diesel Particulate Filter (DPF). Modern DPFs use a honeycomb of long channels with porous walls in order to filter PM with near 100% efficiency. They must be designed to balance trapping efficiency and pressure drop, as flow restriction decreases engine efficiency. This paper describes the construction of two Matlab models in order to predict properties within the filter. Two methods for simultaneously solving the differential conservation equations along with the algebraic ideal gas law in the inlet and outlet channels have been developed. The first method solves the channel equations by transforming the differential algebraic equations (DAEs) into an ordinary differential equation (ODE) system. In addition, a second method is developed that directly solves DAE systems of index-one. In order to link the inlet and outlet channel profiles, modeling of the wall flow is necessary. Four permeability models from different disciplines are used in Darcy’s law to determine their applicability in calculating DPF wall velocity profiles. The resulting inlet, wall, and outlet parameters are compared with published results to demonstrate each model’s accuracy.
