Įvadas. Pastarąjį dešimtmetį sergančiųjų išsėtine skleroze (IS) darbingumo lygiui nustatyti taikoma biopsichosocialiniu požiūriu paremta Tarptautinė funkcionavimo, neįgalumo ir sveikatos klasifikacija (TFK) ne tik prisideda prie sergančiųjų būklės nustatymo, bet ir siūlo priemones geresnei jų įtraukčiai į visuomenę. Visgi Lietuvoje TFK principai darbingumo lygiui nustatyti taikomi fragmentiškai, dažniau remiamasi biologiniais ir fiziniais asmens sveikatos būklės parametrais. Šio darbo tikslas – atlikti išsamų Lietuvos sergančiųjų IS biopsichosocialinį vertinimą ir nustatyti, kaip jų darbingumo lygis siejasi su TFK įvairių kategorijų rezultatais. Tiriamieji ir tyrimo metodai. Atliktame skerspjūvio tyrime dalyvavo 184 asmenys, sergantys IS, – 157 pacientai, kurie kreipėsi į Neįgalumo ir darbingumo nustatymo tarnybą prie Socialinės apsaugos ir darbo ministerijos (NDNT) ir jiems buvo nustatytas darbingumo lygis, ir 27 sergantys IS asmenys, kurie į NDNT dar nesikreipė. Tiriamieji buvo apklausti, taikant trumpąjį TFK kategorijų rinkinį išsėtinei sklerozei, surinkti jų sociodemografiniai ir ligos duomenys. Rezultatai. Net 66 % sergančiųjų IS nurodė, kad jiems labai sunku judėti kitais nei ėjimas būdais (TFK kategorija d455), 32 % sunkumas yra mokamas darbas (d850). Net 81 % sergančiųjų IS aukštesniosios pažinimo funkcijos (b164) nesudaro sunkumų, 63 % pacientų sunkumų nesudaro dienos režimo laikymasis (d230), 57 % – problemų sprendimas (d175). 7–10 % susiduria su nepalankiomis šeimos narių ar sveikatos priežiūros specialistų nuostatomis jų atžvilgiu ir tai jiems yra kliuvinys. Asmenys, kurių darbingumo lygis siekia tik 0–25 %, patiria didesnių sunkumų beveik visose TFK kategorijose, nei tie, kurių darbingumas yra didesnis. Pacientai, kurių darbingumo lygis prilygsta 30–40 %, turi daugiau sunkumų dėl regos, šlapinimosi, raumenų jėgos funkcijų, ėjimo, judėjimo kitais nei ėjimas būdais, nei tie tiriamieji, kurių darbingumo lygis siekia 45–55 %, ir patiria daugiau sunkumų dėl judėjimo funkcijos bei turi labiau pakitusią galvos smegenų struktūrą nei tie, kurių darbingumo lygis yra 60–100 %. Išvados. Ne visų TFK kategorijų ryšiai su sergančių IS darbingumo lygiu yra vienodi. Kuo didesnis asmens darbingumo lygis, tuo mažiau kliuvinių TFK kategorijų vertinime nurodo sergantieji IS.

Full textAbstract:
Stochastic modelling of gene regulatory networks provides an indispensable tool for understanding how random events at the molecular level influence cellular functions. A common challenge of stochastic models is to calibrate a large number of model parameters against the experimental data. Another difficulty is to study how the behaviour of a stochastic model depends on its parameters, i.e. whether a change in model parameters can lead to a significant qualitative change in model behaviour (bifurcation). In this paper, tensor-structured parametric analysis (TPA) is developed to address these computational challenges. It is based on recently proposed low-parametric tensor-structured representations of classical matrices and vectors. This approach enables simultaneous computation of the model properties for all parameter values within a parameter space. The TPA is illustrated by studying the parameter estimation, robustness, sensitivity and bifurcation structure in stochastic models of biochemical networks. A Matlab implementation of the TPA is available at http://www.stobifan.org .

Crack propagation until fracture is an important criterion to predict a structure‘s service life. In order to increase the latter, the cracked component needs to be repaired or replaced. In the present study, a finite element analysis has been carried out to investigate the effects of adhesive thickness, patch thickness and crack length on the passive repair performance of a center-cracked rectangular aluminum plate under mode-I loading condition using an ANSYS package. A comprehensive parametric study shows that the stress intensity factor is influenced by the patch thickness, patch size, adhesive material, and adhesive thickness.

The present study is based on the assay of four markers (AFP, CEA, TPA, Ca 19-9) using IRMA methods in 36 normal subjects, 44 cirrhosis and 66 HCC patients. Parametric and non parametric tests were used to test differences and correlations. ROC curves and discriminant functions were also elaborated. Normal 95% “cut-off” was determined by the “boostrap” method yielding: CEA 3.4 ng/ml; Ca 19-9 55 U/ml; TPA 58U/l and AFP 5.2 ng/ml. In HCC patients the values of the four markers were, on average, significantly different from those of normal subjects. However, only AFP and TPA exhibited high diagnostic accuracy (90%) for detection of the tumor. Higher than normal mean values for all markers were, also observed in cirrhotic patients. Only AFP yielded effective discrimination between HCC and cirrhosis. The positive prediction for the presence of the tumor on cirrhotic ground was 95% for AFP values higher than 18.5 ng/ml, with a 78% negative predictive value with a 6 ng/ml threshold. Association of AFP with TPA showed only a marginal diagnostic improvement. Results were not improved at all by combining CEA and Ca 19-9 with AFP and/or TPA. In conclusion, AFP is and remains the best marker for HCC and the only one effective in discriminating of HCC from cirrhosis. TPA may be considered a valid alternative if cirrhosis is not present. CEA and Cal9-9 are of no use.

Abstract The effects of ovarian status on insulin- and phorbol 12-myristate 13-acetate (TPA)-stimulated lipogenic responses, phorbol ester-specific binding to protein kinase C (PKC) and immunoblot-quantified β- and ε-PKC isoform levels were compared in female rat fat cells from subcutaneous and deep intra-abdominal (parametrial) fat deposits. In control rats, the cytosolic PKC content per cell was 70% lower in subcutaneous than in parametrial adipocytes. In subcutaneous and parametrial fat cells, the cytosolic PKC contents were reduced by ovariectomy and restored to normal by the administration of ovarian hormones (oestradiol plus progesterone). However, the lipogenic response to TPA was unaltered by ovarian status in both fat deposits, contrasting with the insulin-stimulated lipogenic response. This response increased in parametrial fat cells after ovariectomy and returned to normal after ovarian hormone treatment whereas, in subcutaneous fat cells, the insulin response was either unaltered by ovariectomy or increased by the administration of ovarian hormones. This study shows important site-related differences in fat cell PKC content but also reveals a similar modulation of this PKC by ovarian status, regardless of the anatomical localization of the fat cells. The physiological significance of these findings is discussed. Journal of Endocrinology (1994) 140, 275–282

Full textAbstract:
Purpose: The purpose of this work is to increase the possibilities of designing building components for specific demands to increase the building’s value, and to investigate how the possibilities can be affected by automating the production process. Method: The theoretical framework, which this study is based on, was collected using literature studies and was thereafter combined with the empirics, which were retrieved from qualitative methods as interviews and planned observations. A case study was made of the building Ormhuset in Jönköping. Findings: The objective of this work is to investigate the possibilities for designing roofs by using new automation methods for the production process of wooden roof structures. This study implies that parametric design can be used to generate new innovative shapes and designs that are optimised according to specific criteria. Furthermore, an increased use of automation in the production process of wooden roof trusses result in cheaper roof trusses, regardless of their shapes. The generated optimized designs are therefore cheaper and easier to produce using more automation in the production process. Implications: If parametric design is used, almost any kind of shapes can be generated and optimised. To ensure manufacturability of a design, an early connection between architect and manufacturer is important. Furthermore, increased use of automation can lead to easier and faster production of roof trusses and investing in more automation can be relevant for companies with large production volumes. Using digital files to control the manufacturing machines is time saving. There are alternative manufacturing methods for advanced roof structurers in wood, which are better suited for production, which cannot be rationalized as for roof trusses. Constraints for increased automation are often a high investment cost and limited space. Limitations: If the study is performed on another case than Ormhuset and with other respondents, the result might have differed but could be similar, why this study is not generally valid but only shows one possible outcome.Syfte: Syftet med detta arbete är att öka möjligheterna att utforma byggnadsdelar efter specifika behov för att öka en byggnads värde, samt undersöka hur möjligheterna kan påverkas genom att automatisera tillverkningsprocessen. Metod: Den teori som arbetet grundas på har samlats in via litteraturstudier och har därefter kombinerats med empiri som framkommit genom kvalitativa insamlingsmetoder i form av intervjuer och planerade observationer. En fallstudie av byggnaden Ormhuset i Jönköping har genomförts. Resultat: Målet med detta arbete är att studera möjligheter inom utformning av tak som ges av nya automationsmetoder vid tillverkning av takkonstruktioner i trä. Studien har visat att parametrisk design kan användas för att generera nya innovativa former och utformningar som är optimerade utefter specifika kriterier. Vidare kan ökad användning av automation vid tillverkning av takstolar i trä leda till billigare takstolar oberoende av form. De optimerade utformningar som tagits fram blir alltså billigare och lättare att tillverka vid en mer automatiserad tillverkningsprocess. Konsekvenser: Om parametrisk design används kan i stort sett vilka utformningar som helst tas fram och optimeras. För att säkerställa producerbarheten av en utformning är en tidig koppling mellan arkitekt och tillverkare viktig. Vidare kan en ökad automation medföra enklare och snabbare tillverkning av takstolar, och en investering i mer automation kan vara relevant för företag med stora produktionsvolymer. Används digitala produktionsfiler för att styra de tillverkande maskinerna kan tid sparas in. Det finns alternativa produktionssätt för avancerade takkonstruktioner i trä som är bättre lämpade då tillverkningen inte kan rationaliseras på samma sätt som för takstolar. Begränsande faktorer för en ökad automation är ofta en hög investeringskostnad och utrymmesbrist. Begränsningar: Om studien istället utförs för ett annat fall än Ormhuset och därmed med andra respondenter hade kunnat resultera i andra, men kanske snarlika, resultat, varför denna studie inte är generellt giltig utan enbart visar ett möjligt utfall.

La Lean Manufacturing rappresenta l’approccio giapponese del sistema di produzione, in particolare quello di Toyota che prende il nome di Toyota Production System – TPS. Questa filosofia supera i limiti della produzione di massa, approccio tipico delle aziende occidentali, sviluppato inizialmente da Henry Ford e Alfred Sloan. La filosofia alla base della Lean Manufacturing è “fare di più con meno”, ossia ottimizzare i processi produttivi al fine di ridurre al minimo gli sprechi e l’utilizzo di risorse, pur garantendo i volumi produttivi richiesti. Uno dei principali strumenti di questa filosofia è il TPM, acronimo di Total Production Maintenance, che integra la filosofia Lean nel contesto manutentivo degli impianti di produzione e del prodotto stesso.
L’elaborato è strutturato in due parti. La Parte I è dedicata alla teoria legata alla Lean Manufacturing, dove sono presentati i pilastri fondanti e i principali strumenti della filosofia giapponese. Dopo l’introduzione teorica, è presente un caso concreto di applicazione delle tecniche di Lean Manufacturing all’interno di Ducati Motor Holding attraverso l’implementazione di un cantiere Kaizen su un’area produttiva. Diversi sono stati gli strumenti utilizzati durante il cantiere, come i Diagrammi di Ishikawa per individuare le cause radice di un generico problema, la tecnica delle 5S per implementare logiche di standardizzazione, gli Spaghetti Chart per mappare i flussi logistici intra-reparto, ecc.
La Parte II è focalizzata, invece, sulla teoria affidabilistica di un sistema (inteso come un’entità formata da un insieme di componenti). Sono dapprima presentate delle nozioni teoriche sulla teoria affidabilistica utili a comprendere il lavoro svolto nella seconda parte, ossia lo studio affidabilistico di un particolare modello di motocicletta: il Ducati Multistrada 1200. Per il calcolo dei parametri affidabilistici si è utilizzato il software di analisi statistica “Minitab”.

Full textAbstract:
This thesis deals with the evaluation of emissions of NOx and CO formed during the combustion process when the burner utilizing fuel staging and internal flue gas recirculation is used. In the theoretical part the NOx formation mechanisms and methods used to suppress their formation are described. This is followed with the currently valid legislation in the Czech Republic in terms of the emission limits for NOx and CO in stationary sources. In the work, combustion tests were performed at the burners testing facility at UPEI BUT. The tests revealed that the most important parameters, which influence the NOx formation, are fuel staging, increasing combustion air excess and the utilization of new equipment that induces the flue gas to be drawn back into the burner. The equipment is installed in the burner’s air channel. The dependence of flue gas temperature, heat flux to the combustion chamber’s section walls and in-flame temperatures distribution in the horizontal symmetry plane of the combustion chamber on various parameters were investigated. The parameters included the geometry of the equipment for flue gas recirculation, primary/secondary ratio, geometry of nozzles for secondary fuel supply, tangential orientation of these nozzles towards the burner axis, and the excess of combustion air.

Diplomová práce se zabývá spalováním zemního plynu při využití vzduchu s vyšším obsahem kyslíku (21–46 % kyslíku ve spalovacím vzduchu), tzv. kyslíkem obohaceným spalováním (OEC). Technologie OEC nalezla uplatnění v průmyslu, kde se jsou nároky na zvýšenou produktivitu, dosažení vyšší tepelné účinnosti, zlepšení vlastností plamene, snížení náklady, či zlepšení kvality výsledného produktu. Ačkoliv OEC přináší řadu výhod, je nutné zmínit i nevýhody jako: poškození zařízení, nestejnoměrné zahřívání, narušení plamene, zvýšené emise anebo zpětný zášleh plamene. Zkoušky proběhly na zkušebně hořáků, která umožňuje testovat hořáky nejen na plynná a kapalná paliva, ale i hořáky navržené pro kombinované spalování při maximálním výkonu hořáku 1 800 kW. Při zkouškách byl použit plynový „low-NOx“ hořák se stupňovitým přívodem paliva. V diplomové práci je popsán vliv obsahu kyslíku ve spalovacím vzduchu na emise oxidů dusíku (NOx), teplotu plamene, přenos tepla ze spalin do stěn spalovací komory, a také vlastnosti plamene, zvláště pak jeho stabilitu, tvar a rozměry. Zkoušky proběhly při výkonech 300 kW, 500 kW a 750 kW, přičemž pro výkon 750 kW proběhly testy jak při jednostupňové, tak dvoustupňové konfiguraci.

Nous continuerons par une presentation detaillee du detecteur de traces chargees la chambre a projection temporelle. Son bon fonctionnement repose sur un controle precis de la qualite du champ electrique et sur la connaissance a quelques pour mille de la vitesse de derive des electrons dans le gaz utilise (80% argon-20% methane). Ces deux buts sont atteints grace a l'utilisation de lasers ultraviolets qui simulent le passage de traces dans le detecteur. Nous decrivons les etapes franchies tout au long de ce travail depuis la prise de donnees jusqu'a l'analyse finale et l'obtention de la vitesse de derive: 66. 67 mm par microseconde. L'autre partie de cette these porte sur la mesure des parametres du z vecteur de l'interaction faible. Nous commencerons par decrire les predictions theoriques du modele standard ainsi que les corrections radiatives qui entrent en jeu dans la desintegration hadronique du z. Nous presenterons ensuite la methode utilisee pour connaitre la luminosite integree et la selection des desintegrations hadroniques. En combinant ces informations nous determinerons la section efficace experimentale de desintegration du z en hadrons. En ajustant sur ces donnees la forme theorique prevue par le modele standard il est possible de determiner la masse, la largeur et la section efficace de born au pic. Nous obtenons: m=91. 171+/0. 030+/0. 30 gev; l=2. 511+/0. 065 gev; s#0=41. 6+/0. 7+/1. 1 nb. En utilisant ces divers resultats et en les combinant aux predictions du modele standard nous pouvons exclure ) 95% de confiance l'existence d'un quatrieme neutrino de masse inferieure a 38 gev/c#2

Full textAbstract:
The thesis is focused on the experimental investigation of the oxygen enhanced combustion technology (OEC), which uses the combustion air with higher concentration of oxygen, i.e. more than 21 %. The OEC technology is used in those industrial applications, which requires higher thermal efficiency, increased productivity, improved character of the flame, reduced equipment cost, lower volume of exhaust gases and improved product quality. Although this technology involves a number of advantages, it is appropriate to mention some of its disadvantages such as refractory damage, inconsistent heating, increased pollutant emission or flame disturbance and/or flashback. The combustion tests of OEC were carried out at the burners testing facility that enables to test many types of burners (gaseous, liquid, or combined). The two-staged low-NOx burner fired by natural gas was used during the tests. The observed parameters include the effect of oxygen concentration in the combustion air on the NOx emissions, heat flux into the wall of the combustion chamber, in-flame temperature distribution in the horizontal symmetry plane of the combustion chamber and also the shape and dimensions of the flame. The combustion tests of the air-enrichment, air-oxy/fuel and O 2 lancing OEC methods were carried out at the burner thermal input of 750 kW and air excess of 1,1 for two combustion regimes, namely one-staged and two-staged fuel supply.

Full textAbstract:
The literature on the locus of negation in syntactic structure focuses primarily on the position of negation relative to the spine of the clause, the Inflectional Phrase (IP/TP), and whether the negative phrase (NegP) follows or precedes TP. Of particular debate is whether or not the locus of NegP is a parametric choice whereby the Individual/Internal Language (I-Language) of the speaker has the locus of NegP set to one of the two options available in Universal Grammar (UG). The alternative view is that NegP can project below or above TP and can have multiple positions within the structure, each with different syntactic and semantic effects. This chapter discusses both views and proposes a multi-locus analysis for negation in Arabic. After a discussion of these two views, I discuss key issues in the syntax of subjects, verb movement, and tense and aspect in Arabic. These topics are intimately related to the syntax of negation and the analyses presented in this and the subsequent chapters of this monograph. I then present the multi-locus analysis advancing empirical and theoretical arguments from key word order generalizations involving adverbs, subjects, complementizers, and the verbal copula.

Full textAbstract:
Exploiting parallels between nominal and clausal structures, it is argued that the strong / weak D dimension of parametric variation for nominals can be extended to clauses, such that V2 syntax can be reinterpreted as the reflex of a strong C setting. On this view, we observe in the history of most Gallo-Romance varieties a parametric shift from strong to weak C manifested in the loss of generalized V-to-C movement and the concomitant reassignment of the EPP edge-feature from CP to TP, as witnessed in the emergence of a dedicated preverbal subject position and reversal in the null-subject parameter. Within this scenario, it is shown that Gascon represents a major exception having uniquely retained its medieval V2 syntax and, indeed, further extended it to embedded contexts. In particular, in the passage from medieval to modern Gascon, the grammar has witnessed a radical change in the formal realization of the strong C head requirement (while the accompanying EPP edge-feature remains unchanged) such that strong C is no longer satisfied through the Move option raising the finite verb to the C position, but through the Merge option directly lexicalizing the latter position with a so-called ‘enunciative’ particle. This development is the result of intensive contact with Basque, a language independently known to present similar preverbal particles, highlighting how the medieval Gallo-Romance V2 constraint was exceptionally reinforced in this area, but at the same time aligned with a Basque model triggering a shift from the Move to the Merge options in satisfaction of strong C and the emergence of an elaborate system of C-particles.

In ASME 2019 Pressure Vessels & Piping Conference. American Society of Mechanical Engineers, 2019. http://dx.doi.org/10.1115/pvp2019-93240.
Full textAbstract:
Abstract Failure assessment of a pipe with a circumferential crack in a nuclear power plant has to conform to the Rules on Fitness for Service for Nuclear Power Plants published by JSME (The Japan Society of Mechanical Engineering) [1] in Japan. Based on the rules, the applied stresses considered in the failure assessment of the pipe using limit load assessment are membrane, bending, and thermal stresses. The failure assessment focuses only on mode I. In actual plants, depending on the piping system, there is a possibility that torsional stress [2] is applied to the pipe, in addition to membrane, bending, and thermal stresses. Under such a load condition, the crack opening mode will be mixed-mode. In ASME Boiler & Pressure Vessel Code section XI, the bending and torsional moment are considered in failure assessment of the pipe. Therefore, it is important to establish the failure assessment method for the pipe with the crack under mixed-mode. In this study, the XFEM (extended Finite Element Method) [3][4] was applied to assess failure of the austenitic stainless steel pipe (Type 304) with a circumferential crack subjected to bending and torsional moment. XFEM does not require elemental division considering the crack shape and its propagation path. Therefore, the time and cost for developing the analysis model can be reduced compared with conventional FEA (Finite Element Analysis). Fracture test results conducted under two conditions were used the analysis (Specimen No. TP1 and TP2) for determining the energy release rate for crack propagation and verifying the analysis results. The difference between the two tests was the ratio of torsional moment to bending moment. The ratios in TP1 and TP 2 were 0.6 and 1.2, respectively. A parametric analysis was conducted to determine the critical equivalent strain energy release rate required for crack initiation and propagation by comparison with TP1 results. The determined critical equivalent strain energy release rate was verified by comparison with TP2 results. In response to the above considerations, the decreasing load due to crack propagation in the fracture tests under mixed-mode condition was simulated by XFEM, and the maximum load, bending moment, and torsional moment were predicted within the margin of error of 6.1%.

Anaerobinis dumblo stabilizavimas yra vienas plačiausiai pasaulyje taikomų dumblo apdorojimo būdų. Šio proceso metu ne tik sumažinamas dumblo kiekis (iki 50 %), bet ir pašalinamas nemalonus dumblo kvapas bei patogeniniai mikroorganizmai, susidaro šalutinis produktas – biodujos. Anaerobinio pūdymo proceso efektyvumui turi įtakos įvairūs aplinkos veiksniai ir technologiniai parametrai, vienas jų – dumblo tiekimo režimas. Tyrimu atlikta keturių Lietuvos miestų nuotekų valyklų lyginamoji analizė pagal pirminio ir perteklinio dumblo kokybę, dumblo mišinio proporcinę sudėtį ir aplinkos veiksnius bei technologinius parametrus. Lyginant atrinktų valyklų dumblo pūdymą apibūdinančius rodiklius, nustatyta, kad du kartus trumpesnis dumblo tiekimo į pūdymo grandį ciklas, kai jo metu tiekimo trukmė sudarė 4 h, o pauzė – 2 h, sąlygojo 29 % didesnį BSM dalies SM kiekio atžvilgiu sumažėjimą pūdymo proceso metu bei 8,2 % didesnę metano koncentraciją biodujose.

Metodas taikomas ex-situ principu, todėl jo kaina santykinai yra didesnė, lyginant su in-situ (didžiąją kainos dalį sudaro ne cheminiai reagentai, bet grunto nukasimo, pervežimo ir sandėliavimo darbai). Nepaisant didesnės kainos, šis dirvožemio valymo būdas yra efektyvus ir greitas. >80 % išvalymo efektyvumą galima pasiekti per kelias valandas. Nepaisant aukšto efektyvumo, šis dirvožemio valymo metodas Lietuvoje iki šiol nebuvo taikytas. Straipsnyje nagrinėjamas cheminės ekstrakcijos metodo, naudojant organines rūgštis, taikymas nikelio (toliau – Ni) užterštam dirvožemiui valyti.

Full textAbstract:
A parametric analysis which investigates the effects of the hull main dimensions on the seakeeping comfort was proposed to improve a standard SWATH vessel. This study was numerically carried out involving some comfort parameters and worldwide sea conditions. Some types of SWATH and their non-dimensional ratios were considered. The main dimensions of a standard SWATH vessel are: length (L), beam (B), pontoons radius (R), draft (T) and strut thickness (t). Some secondary dimensions were assumed so that a parametric model of wet surface could be designed using MULTISURF, which later was used on WAMIT to evaluate the hydrodynamics coefficients. The TPN receives these coefficients as a basic tool to provide the dynamic response of each SWATH case. The parametric comfort analysis was performed using three usual methodologies applied to evaluate the ship behavior: The ISO2631/3 Severe Discomfort, the MSI (Motion Sickness Incidence) and the VI (Vomiting Incidence).

Full textAbstract:
Southern China has been subject to some of the deadliest typhoons in history with records going back over a thousand years. Before the large waves associated with a typhoon reach the mainland of China there is a delay between the typhoon reaching landfall and the time of the extreme waves arriving. This paper focuses on an approach to simulate this lag in the waves reaching landfall in the Qiongzhou Strait in southern China. A numerical approach has been adopted to simulate the typhoon and wave processes using a parametric typhoon model and the SWAN wave model. Two typhoon events are simulated (typhoon Kai-Tak in 2012 and typhoon Jebi in 2013) and used to tune the parameters for the numerical models. The simulated wind speeds and significant wave heights of the typhoon are compared with measured data. For the simulation of typhoon Kai-Tak, the correlation coefficient gives an 87% agreement between the simulated and measured values of wave height with a standard deviation of 0.29 m. For typhoon Jebi the fit is less good (66%). However, the simulation results have provided insight into improving the parametric typhoon model.
