description: Abstract: "Process optimization problems are frequently characterized by large models, with many variables and constraints but relatively few degrees of freedom. Thus, reduced Hessian decomposition methods applied to Successive Quadratic Programming (SQP) exploit the low dimensionality of the subspace of the decision variables, and have been very successful for a wide variety of process application. However, further development is needed for improving the efficient large-scale use of these tools. In this study we develop an improved SQP algorithm decomposition with coordinate bases that includes an inexpensive second order correction term. The resulting algorithm is 1-step Q-superlinearly convergent. More importantly, though, the resulting algorithm is largely independent of the specific decomposition steps. Thus, the inexpensive factorization of the coordinate decomposition, which lends itself very well to tailoring, can be applied in a reliable and efficient manner. With this efficient and easy-to-implement NLP strategy, we continue to improve the efficiency of the optimization algorithm by exploiting the mathematical structure of existing process engineering models. Here we consider the tailoring of a reduced Hessian method for the block tridiagonal structure of the model equations for distillation columns. This approach is applied to the Naphthali-Sandholm algorithm implemented within the UNIDIST and programs. Our reduced Hessian SQP strategy is incorporated within the package with only minor changes in the program's interface and data structures. Through this integration, reductions of 20% to 80% in the total CPU time are obtained compared to general reduced space optimization; an order of magnitude reduction is obtained when compared to conventional sequential strategies. Consequently, this approach shows considerable potential for efficient and reliable large-scale process optimization, particularly when complex Newton-based process models are already available."

description: We present a ground motion model for the SLAC site. This model is based on recent ground motion studies performed at SLAC as well as on historical data. The model includes wave-like, diffusive and systematic types of motion. An attempt is made to relate measurable secondary properties of the ground motion with more basic characteristics such as the layered geological structure of the surrounding earth, depth of the tunnel, etc. This model is an essential step in evaluating sites for a future linear collider.

description: Background and aims: A wide range of treatment options are available for hepatocellular carcinoma (HCC), including systemic treatment with tyrosine kinase inhibitors (TKIs) such as sorafenib and lenvatinib, immunotherapies, locoregional therapies such as selective internal radiation therapy (SIRT) and treatments with curative intent such as resection, radiofrequency ablation and liver transplantation. Given the substantial economic burden associated with HCC treatment, the aim of the present analysis was to establish the cost of using SIRT with SIR-Spheres yttrium-90 (Y-90) resin microspheres versus TKIs from healthcare payer perspectives in France, Italy, Spain and the United Kingdom (UK). Methods: A cost model was developed to capture the costs of initial systemic treatment with sorafenib (95%) or lenvatinib (5%) versus SIRT in patients with HCC in Barcelona Clinic Liver Cancer (BCLC) stages B and C. A nested Markov model was utilized to model transitions between progression-free survival (PFS), progression and death, in addition to transitions between subsequent treatment lines. Cost and resource use data were identified from published sources in each of the four countries. Results: Relative to TKIs, SIRT with SIR-Spheres Y-90 resin microspheres were found to be cost saving in all four country settings, with the additional costs of the microspheres and the SIRT procedure being more than offset by reductions in drug and drug administration costs, and treatment of adverse events. Across the four country settings, total cost savings with SIR-Spheres Y-90 resin microspheres fell within the range 5.4–24.9% and SIRT resulted in more patients ultimately receiving treatments with curative intent (4.6 vs. 1.4% of eligible patients). Conclusion: SIR-Spheres Y-90 resin microspheres resulted in cost savings relative to TKIs in the treatment of unresectable HCC in all four country settings, while increasing the proportion of patients who become eligible for treatments with curative intent.
Clinicopathologic aspects of chronic fluoride toxicosis in cattle.

name: Olsen, A. E.
Publisher: name: The Bovine Practitioner
Year: 1987

description: Cattle normally ingest small amounts of fluoride without evidencing adverse effects. Excessive fluorides may be from a variety of combination of sources. Responses to fluorides are influenced by a number of factors. Excessive levels can induce an acute, subacute or an insidious chronic toxicosis. Fluorides accumulate primarily in developing teeth and in bone, where major fluoride-induced lesions occur. Characterization of clinical signs and lesions and classification criteria have been developed to help standardize the diagnosis and evaluation of fluorosis. Teeth are adversely affected during their development, but bones may be affected throughout an animals lifetime. Supportive diagnostic criteria and aids are discussed and procedures and techniques that may partially protect cattle from chronic fluoride toxicosis are presented. Recommended tolerance standards for various ages and types of cattle are also given.

description: Il rispetto delle regole e un clima di classe sereno e accogliente permettono agli allievi di apprendere meglio e con maggiore facilità. La conoscenza delle regole in alcuni casi non è sufficiente agli alunni, che faticano a rispettarle. Come poterli aiutare ad acquisire maggiore consapevolezza rispetto al proprio comportamento e alle conseguenze? Nella prima fase esplorativa sono stati raccolti dati osservativi in classe, confrontati con un’analisi secondaria sulle dimensioni oggetto d’indagine. Le evidenze raccolte consentono di osservare un lieve miglioramento sull’attenzione alle regole attraverso esercizi autovalutativi. Sono emerse tre dimensioni: silenzio, tono di voce e distrazione. Dal connubio fra queste informazioni e fonti secondarie si è potuto ad esempio evidenziare che il silenzio è alla base della relazione educativa ed è fondamentale per la comprensione. I soggetti lo necessitano ma allo stesso tempo lo respingono sia perché hanno difficoltà di cambiamento sia perché lo temono, in quanto hanno paura di confrontarsi con se stessi.

description: Solving the Fokker-Planck equation for high-dimensional complex turbulent dynamical systems is an important and practical issue. However, most traditional methods suffer from the curse of dimensionality and have difficulties in capturing the fat tailed highly intermittent probability density functions (PDFs) of complex systems in turbulence, neuroscience and excitable media. In this article, efficient statistically accurate algorithms are developed for solving both the transient and the equilibrium solutions of Fokker-Planck equations associated with high-dimensional nonlinear turbulent dynamical systems with conditional Gaussian structures. The algorithms involve a hybrid strategy that requires only a small number of ensembles. Here, a conditional Gaussian mixture in a high-dimensional subspace via an extremely efficient parametric method is combined with a judicious non-parametric Gaussian kernel density estimation in the remaining low-dimensional subspace. Particularly, the parametric method provides closed analytical formulae for determining the conditional Gaussian distributions in the high-dimensional subspace and is therefore computationally efficient and accurate. The full non-Gaussian PDF of the system is then given by a Gaussian mixture. Different from the traditional particle methods, each conditional Gaussian distribution here covers a significant portion of the high-dimensional PDF. Therefore a small number of ensembles is sufficient to recover the full PDF, which overcomes the curse of dimensionality. Notably, the mixture distribution has a significant skill in capturing the transient behavior with fat tails of the high-dimensional non-Gaussian PDFs, and this facilitates the algorithms in accurately describing the intermittency and extreme events in complex turbulent systems.

description: It is known that the spectral energy distribution (SED) of the nuclear radiation of narrow-line Seyfert 1 galaxies (NLS1s) has different shapes with respect to that of ordinary broad-line Seyfert 1 galaxies (BLS1s), particularly in wavelengths of X-ray. This may cause some differences in the ionization degree and the temperature of gas in narrow-line regions (NLRs) between NLS1s and BLS1s. This paper aims to examine whether or not there are such differences in the physical conditions of NLR gas between them. For this purpose, we have compiled the emission-line ratios of 36 NLS1s and 83 BLS1s from the literature. Comparing these two samples, we have found that the line ratios of [O {\sc i}]$λ$6300/[O {\sc iii}]$λ$5007 and [O {\sc iii}]$λ$4363/[O {\sc iii}]$λ$5007, which represent the ionization degree and the gas temperature respectively, are statistically indistinguishable between NLS1s and BLS1s. Based on new photoionization model calculations, we show that these results are not inconsistent with the difference of the SED between them. The influence of the difference of SEDs on the highly ionized emission lines is also briefly discussed.

We critically discuss a possible explanation for this unexpected behavior. On the other hand the fourth-moment sum-rule turns out to be able to account for the results of the simulations at criticality.

description: Aims: To evaluate total costs and health consequences of a colorectal cancer (CRC) screening program with colonoscopy, fecal immunochemical tests (FIT), and expanded use of multitarget stool DNA (mt-sDNA) from the perspectives of Integrated Delivery Networks (IDNs) and payers in the United States. Materials and methods: We developed a budget impact and cost-consequence model that simulates CRC screening for eligible 50- to 75-year-old adults. A status quo scenario and an increased mt-sDNA scenario were modeled. The status quo includes the current screening mix of colonoscopy (83%), FIT (11%), and mt-sDNA (6%) modalities. The increased mt-sDNA scenario increases mt-sDNA utilization to 28% over 10 years. Costs for both the IDN and the payer perspectives incorporated diagnostic and surveillance colonoscopies, adverse events (AEs), and CRC treatment. The IDN perspective included screening program costs, composed of direct nonmedical (e.g. patient navigation) and indirect (e.g. administration) costs. It was assumed that IDNs do not incur the costs for stool-based screening tests or bowel preparation for colonoscopies. Results: In a population of one million covered lives, the 10-year incremental cost savings incurred by increasing mt-sDNA utilization was $16.2 M for the IDN and $3.3 M for the payer. The incremental savings per-person-per-month were $0.14 and $0.03 for the IDN and payer, respectively. For both perspectives, increased diagnostic colonoscopy costs were offset by reductions in screening colonoscopies, surveillance colonoscopies, and AEs. Extending screening eligibility to 45- to 75-year-olds slightly decreased the overall cost savings. Limitations: The natural history of CRC was not simulated; however, many of the utilized parameters were extracted from highly vetted natural history models or published literature. Direct nonmedical and indirect costs for CRC screening programs are applied on a per-person-per modality basis, whereas in reality some of these costs may be fixed. Conclusions: Increased mt-sDNA utilization leads to fewer colonoscopies, less AEs, and lower overall costs for both IDNs and payers, reducing overall screening program costs and increasing the number of cancers detected while maintaining screening adherence rates over 10 years.
Plasma transfusions in failure of colostral immunoglobulin transfer (1).

Publisher: name: The Bovine Practitioner
Year: 1987

description: Partial or complete failure of colostral immunoglobulin transfer (FCIT) is frequently encountered in neonatal calves and is associated with increased morbidity and mortality. Therapy for FCIT and associated diseases may include administration of antimicrobials, fluids, various supportive measures and attempts to restore protective levels of circulating immunoglobulins (Ig). Because FCIT is frequently encountered after gut closure to absorption of exogenous Ig, administration of Ig in plasma or whole blood has been used to restore protective levels of Ig. Recommendations for plasma administration to neonatal calves are empirical and have been based upon practices commonly used in neonatal foals. A commonly recommended dose is administration of plasma at 20ml/kg body weight. In the present study, plasma administration was studied in newborn calves with FCIT. The purposes of the study were: 1.) To determine if administration of plasma at 20ml/kg would produce protective levels of circulating Ig in calves with FCIT; and 2.) To compare levels of circulating Ig in calves administered plasma IP once, IV once, and IV twice with 7 days between dosing. In addition, calves with FCIT and administered plasma were compared to calves receiving colostrum.

description: This paper addresses the solution of a two-stage stochastic programming model for an investment planning problem applied to the petroleum products supply chain. In this context, we present the development of acceleration techniques for the stochastic Benders decomposition that aim to strengthen the cuts generated, as well as to improve the quality of the solutions obtained during the execution of the algorithm. Computational experiments are presented for assessing the efficiency of the proposed framework. We compare the performance of the proposed algorithm with two other acceleration techniques. Results suggest that the proposed approach is able to efficiently solve the problem under consideration, achieving better performance in terms of computational times when compared to other two techniques.

In addition to translation invariance and the expected three remaining Lorentz symmetries characterized by the little group of the external vector, the model possesses an additional spacetime symmetry if the nondynamical vector is lightlike. The conserved current associated with this invariance is determined, and the symmetry structure arising from this invariance and the usual little group ISO(2) is identified as SIM(2).

Measurement and Correction of Cross-Plane Coupling in Transport Lines

Year: 2000

description: In future linear colliders the luminosity will depend on maintaining the small emittance aspect ratio delivered by damping rings. Correction of cross-plane coupling can be important in preventing dilution of the beam emittance. In order to minimize the vertical emittance, especially for a flat beam, it is necessary to remove all cross-plane (x-y) correlations. This paper studies emittance measurement and correction for coupled beams in the presence of realistic measurement errors. The results of simulations show that reconstruction of the full 4x4 beam matrix can be misleading in the presence of errors. We suggest more robust tuning procedures for minimizing linear coupling.

Effects of slatted flooring on claw shape in intensively housed fattening beef cattle
Creators: name: Murphy, Peter A.

Publisher: name: The Bovine Practitioner
Year: 1987

description: Intensivism in the Irish beef industry is a recent and fast-developing process involving the concentration of cattle into large slatted floor houses where they are confined for a six-month winter period. Surveys carried out to assess any alterations in the disease pattern as a result of changing to slatted floors from traditional straw yard housing indicated that twice as much disease (10% incidence) was encountered on slatted floors as on straw yard (5% of cattle). Lameness with an incidence of five percent of cattle affected was the most serious disease problem on slats and the major lesion causing lameness was septic traumatic pododermatitis which accounted for 43 percent of all lameness cases. Surveys of defects of claws post-mortem indicated that abrasion of the white line was the primary inciting cause of bruising and penetration at the white line though ungulysis or chronic foot rot was an important secondary cause. Abrasion of hoof horn was considered a function of two factors—floor construction and horn quality. Accordingly to assess the influence of floor construction on claw shape through abrasion the rates of horn growth and wear were measured in beef cattle housed either on slats or on straw over a six-month winter period.

description: To understand the essential physics needed to reproduce magnetic reconnection events in 2.5-D particle-in-cell (PIC) simulations, we revisit the Geospace Environmental Modeling (GEM) setup. We set up a 2-D Harris current sheet (that also specifies the initial conditions) to evolve the reconnection of antiparallel magnetic fields. In contrast to the GEM setup, we use a much smaller initial perturbation to trigger the reconnection and evolve it more self-consistently. From PIC simulation data with high-quality particle statistics we study a symmetric reconnection site, including separatrix layers, as well as the inflow and the outflow regions. The velocity distribution functions (VDFs) of electrons have a fine structure and vary strongly depending on their location within the reconnection setup. The goal is to start cataloging multidimensional fine-structured electron velocity distributions showing different reconnection processes in the Earth's magnetotail under various conditions. This will enable a direct comparison with observations from, e.g., the NASA Magnetospheric MultiScale (MMS) mission, to identify reconnection-related events. We find regions with strong non-gyrotropy also near the separatrix layer and provide a refined criterion to identify an electron diffusion region in the magnetotail. The good statistical significance of this work for relatively small analysis areas reveals the gradual changes within the fine structure of electron VDFs depending on their sampling site.

description: I discuss the recent progress in our understanding of nucleosynthesis via rapid neutron capture, the r-process, based on meteoritic data for the early solar system and observations of stars at low metallicities. At present, all data require that there be two distinct kinds of r-process events and suggest that supernovae are associated with these events. The diversity of supernova sources for the r-process may depend on whether a neutron star or black hole is formed in an individual supernova. This dependence, if substantiated by future observations discussed here, has important implications for properties of nuclear matter.

description: A monoclonal antibody characterized bovine paralytic rabies (BPR) virus isolate, ATC vr-985, was inoculated intrathecally (i.t.) or intralingually (i.l.) into 13 Holstein calves (5 controls) weighing 66±15 kg. Infected calves with the highest dose stopped growing earlier, later with the lowest dose: collapse (loss in body weight) was at a steady negative daily rate. Growth rates, collapse rates and chronology were predictable and reproducible, and the kinetics verified in a rabbit model. The BPR virus was found in large numbers in lower and upper spinal cord, cerebellum and hypothalamus. The best diagnostic specimen was the trigeminus nerve, followed by the cerebellum. Immunoperoxidase-PAP staining made Negri bodies very apparent particularly in the hypothalamus. The marked presence of BPR virus in the cerebellum coincided with obvious motor and equilibrium changes. A chronogram of clinical manifestations in 3 calves injected i.t. is presented. Effects on growth, and the linear regression analysis of the different titrations applied to the wasting syndrome phenomenon, are among the aspects tabulated or shown graphically. There are several microphotographs. It is concluded that experimental BPR was clinically indistinguishable from the field disease. It is postulated that BPR acts upon the hypothalamic/hypophysiary/thymic axis by its tendency to infect the hypothalamus and the (adeno-) hypophysis, impairing the production of somatotropic (growth) hormone.

description: We present the results of theoretical analysis and numerical simulations of the Weibel instability in two counter-streaming hot relativistic plasma flows, e.g. flows of electron-proton plasma having rest-mass density $ρ\sim 10^{-4}\; \text{g}\, \text{cm}^{-3}$, Lorentz factors $Γ\sim 10$ and proper temperature $T \sim 10^{13}\; \text{K}$. The instability growth rate and the filament size at the linear stage are found analytically, and are in qualitative agreement with results of three-dimensional particle-in-cell simulations. In the simulations, incoherent synchrotron emission and pair photoproduction in electromagnetic fields are taken into account. If the plasma flows are dense, fast and/or hot enough, the overall energy of synchrotron photons can be much larger than the energy of generated electromagnetic fields. Furthermore, a sizable number of positrons can be produced due to the pair photoproduction in the generated magnetic field. We propose a rough criterion for judging copious pair production and synchrotron losses. By means of this criterion we conclude that incoherent synchrotron emission and pair production during the Weibel instability can have implications for the collapsar model of gamma-ray bursts.

La rappresentazione inclusiva della disabilità nella materia italiano: proposta di un percorso didattico
Creators: name: Riva, Laura
Publisher: name: Scuola Universitaria della Svizzera Italiana (SUPSI)
Year: 2023
Subjects: disabilità – inclusione – italiano – rappresentazione – diversità

description: L’obiettivo del presente lavoro di diploma è quello di indagare i benefici di un percorso didattico relativo alla disabilità, tenendo presente i principi del contesto di formazione generale “vivere assieme ed educazione alla cittadinanza” presente nel Piano di studio della scuola dell’obbligo ticinese. La modalità scelta è quella della ricerca azione. È stato ideato un percorso didattico di tre lezioni da sottoporre a una classe di seconda media. Agli allievi è stato somministrato un questionario prima di svolgere le lezioni, che è stato poi riproposto alla fine del percorso allo scopo di misurarne eventuali cambiamenti ed evoluzioni. Oltre a questi dati quantitativi, sono stati anche raccolti degli elementi qualitativi dalla redazione di un commento finale da parte degli allievi. La domanda di ricerca e le ipotesi annesse hanno trovato risposta solo in parte; tuttavia, sebbene non si possa affermare l’efficacia scientifica del percorso didattico, esso ha senz’altro permesso di evidenziare l’importanza di portare tematiche relative all’inclusione all’interno della scuola media, così come i benefici che ne sono risultati.

Year: 2024

description: This deliverable presents the updated use case scenarios and requirement analysis of the AI-PRISM system design. It includes the description of the five different use cases of the AI-PRISM project and the related key performance indicators (KPIs). Furthermore, the deliverable contains the set of hierarchical requirements for subsequent system development: the high-level requirements identified so far by the stakeholders, and the system requirements (related to Hardware, Human Robot Collaboration aspects, the AI Enhancing Tools and the Social Collaboration aspects) resulting from the analysis of the stakeholder requirements. In addition, the requirement analysis also includes a mapping between the pilot requirements and the responsible technical components. This deliverable extends and updates D1.2 with respect to the use case descriptions and the KPIs. The use cases descriptions give a thorough overview of the current situations and the envisioned collaborative scenarios. Details about a Technology Pull / Technology Push methodology that supported the refinement of the use case definitions and the mapping of stakeholder requirements to system requirements is also given. Additionally, the key human factors dealt in each use case are also described in detail.

description: Mg-9Al-1Zn (AZ91) magnesium matrix composites reinforced by Ti-6Al-4V (TC4) particles were successfully prepared via powder metallurgical method. The yield strength (YS), ultimate tensile strength (UTS), and elongation (EL) showed a mountain-like tendency with the increase of the TC4 content. The mechanical properties of AZ91 magnesium matrix composites reached the optimal point with TC4 content of 10 wt.%, realizing YS, UTS, and EL of 335 MPa, 370 MPa, and 6.4%, respectively. The improvement of mechanical properties can be attributed to the effective load transfer from the magnesium matrix to the TC4 particles, dislocations associated with the difference in the coefficient of thermal expansion, good interfacial bonding between the Mg matrix and TC4 particles, and grain refinement strengthening.
On the D3-brane description of some 1/4 BPS Wilson loops

description: Recently it has been proposed that Wilson loops in high-dimensional representations in N=4 supersymmetric Yang-Mills theory (or multiply wrapped loops) are described by D-branes in AdS_5 x S^5, rather than by fundamental strings. Thus far explicit D3-brane solutions have been only found in the case of the half-BPS circle or line. Here we present D3-brane solutions describing some 1/4 BPS loops. In one case, where the loop is conjectured to be given by a Gaussian matrix model, the action of the brane correctly reproduces the expectation value of the Wilson loop including all 1/N corrections at large λ. As in the corresponding string solution, here too we find two classical solutions, one stable and one not. The unstable one contributes exponentially small corrections that agree with the matrix model calculation.

description: Satellite-based QKD offers the potential to share highly secure encryption keys between optical ground stations all over the planet. SpooQySats is a programme for establishing the space worthiness of highly-miniaturised, polarization entangled, photon pair sources using CubeSat nanosatellites. The sources are being developed iteratively with an early version in orbit already and improved versions soon to be launched. Once fully developed, the photon pair sources can be deployed on more advanced satellites that are equipped with optical links. These can allow for very secure uplinks and downlinks and can be used to establish a global space-based quantum key distribution network. This would enable highly secure symmetric encryption keys to be shared between optical ground stations all over the planet.

Immune response of fasted calves to infectious bovine rhinotracheitis virus.

description: Seventeen calves (Angus, Hereford, and Angus-Hereford crosses) weighing 120-200 kg, were starved for 3 days and inoculated intranasally with a strain of IBR virus after 1 day or 3 days of food deprivation. Although clinical signs of disease were mild in all calves, the signs appeared more severe than those reported by others using the same strain of virus possibly due in part to the use of intranasal inoculation by aerosol vs instillation. Neutralizing antibody response after virus inoculation did not differ beween groups. Of the 17 calves, 16 developed significant increases (seroconversion of 4-fold increase in titre) in IBR serum antibodies. Serum neutralizing antibodies in 3 calves at inoculation did not prevent them from excreting substantial amounts of virus for ? 5 days after virus inoculation. Lymphocytes from fasted and nonfasted calves had similar (essentially negative) blast transformation responses, except 1 fasted seropositive calf (sensitised animal) that had a high stimulation index. Some dehydration was observed in fasted calves, indicated by significant increase in haematocrit. In only 1 group did serum cortisol levels rise significantly, mean values peaking at the end of fasting at the time of inoculation; thereafter, mean values tended to decline. Although the 3-day fast significantly affected some serum and blood components, it did not adversely affect the immune response of calves. One fasted calf developed a significant cell mediated immune response to inactivated IBR virus during infection. It is concluded that acute nutritional deprivation may not necessarily increase the susceptibility of calves to viral infections nor adversely affect their immune response after vaccination. This report represents a portion of a dissertation submitted by the senior author to the graduate faculty of the University of Missouri in partial fulfillment of the requirements for the PhD degree. The authors thank Gary Krause and Mark Ellersieck for aid in statistical analysis and Gerald Buening for help in lymphocyte transformation tests.

description: A short review of the article "Finance's quantum computing teams - and who's hiring".Maybe someone will be interested.It would not be a great exaggeration to say that quantum mechanics is linear algebra, which was given a physical interpretation.When you compress an image, take a photo of something with your smartphone, watch a video on your laptop, or play a video game, you are using technologies that use various elements from linear algebra.Linear algebra, in turn, is built on two basic elements - a matrix and a vector.Linear algebra is essential in many areas of computer science because linear equations are easy to solve. It allows you to bring a large set of problems to matrix form, and as a result we solve the matrix.
Investigations of Slow Motions of the SLAC Linac Tunnel

description: Investigations of slow transverse motion of the linac tunnel of the Stanford Linear Collider have been performed over period of about one month in December 1999 -- January 2000. The linac laser alignment system, equipped with a quadrant photodetector, allowed submicron resolution measurement of the motion of the middle of the linac tunnel with respect to its ends. Measurements revealed two major sources responsible for the observed relative motion. Variation of the external atmospheric pressure was found to be the most significant cause of short wavelength transverse motion of the tunnel. The long wavelength component of the motion has been also observed to have a large contribution from tidal effects. The measured data are essential for determination of parameters for the Next Linear Collider.

description: Abstract: "Previous studies on process integration have generally considered reaction and separation as processes that occur sequentially in a flowsheet. In this paper, a unified formalism is presented for the synthesis of reaction-separation systems, while ensuring 'optimal' energy management. The synthesis model stems from a target-based approach for reactor networks due to an earlier study. It is shown that by postulating a species dependent residence time distribution function, one can arrive at a general representation for a reaction-separation network. Optimization of this distribution function leads to a separation profile as a function of time along the length of the reactor. The synthesis model is formulated as a mixed integer optimal control problem, where the integer variables account for the fixed costs of separation. The control profiles include the temperature, the separation profile, and residence time distribution defined for the network. Costs for maintaining a separation profile are handled through a separation index (defined to model the intensity of separation), and a fixed charge for any separation between two components in the reaction mixture. Also, using an energy targeting formulation, the maintenance of the optimal temperature profile is integrated to the energy flows within the flowsheet. Strategies based on simultaneous optimization and model solution are presented for the optimization problem and demonstrated for two case studies."
