Nonlinear dynamics study of a high-temperature rotor-bearing-seal system in gas turbine
Authors: Zhu Rui , Zhang Yanru , Ren Jianxing , Li Hongguang , Han Qingkai
Published: February 2017

Most of the major faults in gas turbines often originate from the rotor shaft. Some of these faults could result to misalignment, imbalance, crack, rub-impact and eccentricity. This study analyzes nonlinear factors such as lube-film surge and thermal-stress. Seal and bearing quality significantly affect the performance of a rotor system. The nonlinear dynamic characteristics of a high-temperature rotor–bearing–seal coupled system are investigated. Dynamic trajectories, Poincaré maps, frequency spectra diagrams are used to analyze the features of the rotor-bearing-seal coupled system in terms of various parameters. Several nonlinear phenomena in the high-temperature rotor–bearing–seal coupled system, such as periodic, double-periodic, multi-periodic, and quasi-periodic motion are investigated. Through these curves and the program, the dynamic characteristics of gas turbine rotors could be easily and accurately calculated. To validate this method, the critical speed of a real rotor of an actual gas turbine was calculated by means of the program and curves. The results are consistent with the measured data and may contribute to further understanding the nonlinear dynamics of the high-temperature rotor-bearing-seal coupled system.
Axial dynamic load identification of hydraulic turbine based on Chebyshev orthogonal polynomial approximation
Authors: Song Zhiqiang , Liu Yunhe
Published: February 2017

An analysis method is proposed to identify axial dynamic loads acting on the Francis turbine based on Chebyshev orthogonal polynomial expansion theory. Dynamic loads are expressed as functions of time and polynomial coefficients. The dynamic load identification model is constructed through discretized integral convolution of the loads, such as the Duhamel integral. However, the discretized numerical integral has a time-cumulative error problem that decreases the recognition accuracy of the dynamic load. Compared with the traditional method, the algorithm proposed in this paper constructs the relationship between the modal displacement and force using polynomial orthogonality and derivative relation between displacement and velocity or acceleration. The new method could avoid the Duhamel integral and time-cumulative error problem. This algorithm not only requires less measuring point information, but is also highly efficient. Compared with genetic algorithm identification, orthogonal polynomial algorithm is not easy falling into local convergence, and does not require multiple repetitions positive analysis trial to evaluate individual fitness value. Numerical simulations demonstrate that the identification and assessment of dynamic loads are effective and consistent when the proposed method is used.
A dynamic modeling method for helical gear systems
Authors: Yan Ming , Liu Hong-quan
Published: February 2017

Dynamic modeling for gear systems is very important for accurately predicting the dynamic responses during the gear engagements. During the modeling, meshing force must be determined, and it is usually calculated by the product of the relative displacement along the line of action (LOA) and the meshing stiffness. At present, the relative displacement calculation for helical gear systems is very complicated by several existing methods because the complicated geometric relationships need to be derived for determining the spatial positions of two meshing points along LOA. In this study, a simple method for calculating the relative displacement along LOA is presented based on ANSYS software. And on this basis, a new finite element modeling method for a helical gear transmission system with multiple shafts is developed, where the influences of shafts and bearing flexibilities are considered. Moreover, the proposed method is validated by comparing the dynamic characteristics, such as natural characteristics and vibration responses, with those obtained from Kubur’s method and Zhang’s method.
A novel method to analysis strong dispersive overlapping lamb-wave signatures
Authors: Li Hui , Liu Xiaofeng , Bo Lin
Published: February 2017

Dispersive propagation and overlapping wave modes are two main obstacles for guided Lamb wave SHM applications. In an effort to overcome such obstacles, a new signal-processing technique taking advantage order tracking based on dispersion relation, is developed. In this approach, by referencing the wave number-frequency function of specified mode, the operations of resampling and interpolating are performed on the frequency-spectral series of raw signal. The orders referenced to wave number-frequency are calculated, according to which the individual wave-packet is identified and its corresponding propagating distance is estimated. In the order domain, the overlapping modes are readily separated by Gabor expansion on the frequency-spectral series of raw signal. Numerical and FEM simulations on strongly dispersive and multimode overlapping guided waves were carried out to evaluate the performance of the proposed approach. The results demonstrated that the proposed approach is effective in dispersion analysis, mode differentiation and overlapped wave-packets separation.

Authors: Galiotto Rubiane , Noll Patrícia
Published: February 2017

No presente trabalho objetiva-se analisar a relação que existe entre a concessão do Auxílio-Reclusão e a aplicação do Princípio da Igualdade através do método analítico-dedutivo com a análise dos aspectos doutrinários e legais acerca do assunto. A legislação, após a Emenda Constitucional nº 20/1998, prevê o requisito baixa-renda para a concessão do auxílio-reclusão. Desta forma, a concessão do benefício fere o princípio da igualdade visto que é assegurado o benefício previdenciário apenas às famílias dos segurados de baixa-renda. Diante de tal discriminação, as famílias dos segurados reclusos que recebiam valor maior que o estipulado na lei são deixadas desamparadas.

A SIMPLE DYNAMICAL MODEL FOR THE GROWTH OF SMOKER POPULATION
Authors: Gunawan A. Y. , Nurtamam M. E.
Published: February 2017

In this article, a simple dynamical model derived from the SIR Model that has been known in epidemiology is applied to study qualitatively the growth of smoker population in a closed population system. The population in the system is divided into three groups: potential smokers, active smokers, and quitted smokers. We derive the model by assuming that the quitted smokers can relapse into active smokers. The model consists of three nonlinear and autonomous differential equations, and is then investigated by applying the linear stability theory. We find that the increase of a number of smokers mainly depends on three parameters: how big the interaction between an active smoker and a potential smoker, an average time for being a smoker, and an average time for being a quitted smoker before relapsing into an active smoker. These three parameters are represented by a number R0, so called a threshold condition. For R0 > 1, we find that the population of active smokers always exists. Results also show that low interaction is enough to increase a number of active smokers.DOI : http://dx.doi.org/10.22342/jims.14.1.82.63-72

PARAMETRIC EXCITATION IN A SELF-EXCITED THREE-DEGREES OF FREEDOM PROBLEM
Authors: FATIMAH SITI
Published: February 2017

The efect of parametric excitation in self-excited has been investigated in two-degrees of freedom problems. The possibility of suppressing self-excited vibrationsby using parametric excitation and the dynamic behavior of those kind systems were discussed. In the this paper, we consider a system in three-degrees of freedom problem which by using a linear transformation the system becomes an Autoparametric. The system consists of a central mass and two external masses where those masses are conectedby springs with the same constant stiffness. The flow-generated self-excited force is actingon the external masses, it is represented by Rayleigh force. The variable stiffness isperiodically varying in time, represents a parametric excitation. It turns out that forcertain parameter ranges full vibration cancellation is possible. The analysis of linearcase of system shows that there are two conditions in order to obtain an interval ofthe parametric excitation. Using the averaging method the fully non-linear system is investigated producing as non-trivial solutions unstable periodic solutions. The behaviorof this unstable solution is studied in the full system.DOI : http://dx.doi.org/10.22342/jims.15.2.48.97-104
RECIPES FOR BUILDING THE DUAL OF CONIC OPTIMIZATION PROBLEM
Authors: Chaerani Diah
Published: February 2017

Building the dual of the primal problem of Conic Optimization (CO) isa very important step to make the ¯nding optimal solution. In many cases a givenproblem does not have the simple structure of CO problem (i.e., minimizing a linearfunction over an intersection between a±ne space and convex cones) but there areseveral conic constraints and sometimes also equality constraints. In this paper wedeal with the question how to form the dual problem in such cases. We discuss theanswer by considering several conic constraints with or without equality constraints.The recipes for building the dual of such cases is formed in standard matrix forms,such that it can be used easily on the numerical experiment. Special attention isgiven to dual development of special classes of CO problems, i.e., conic quadraticand semide¯nite problems. In this paper, we also brie°y present some preliminariestheory on CO as an introduction to the main topic.DOI : http://dx.doi.org/10.22342/jims.16.1.28.9-23
A TRAVELING PULSE BEHAVIOR OF THE SPREAD OF THE AVIAN FLU VIRUSES AMONG FLOCK AND HUMAN
Authors: Pudjaprasetya S.R. , Gunawan A.Y.
Published: February 2017

We propose two disease transmission models: the SI model with di®u-sive terms as a model for transmission of avian in°uenza viruses among °ock withconstant population density, and the host-vector SI model with di®usive terms fortransmission among °ock and human. There is a threshold number that determinewhether the diseases become epidemic or not. It depends on three parameters: theaverage length of the infective period, the contact parameter, and the density ofsusceptible population at the initial time. With di®usive terms in the model, thespatial spread of the infection is obvious. Threshold number greater than one isalso the necessary condition for the spreading of infection in the form of a travelingpulse. Its minimum velocity can be determined. We implement the MacCormackmethod, and simulate the generation of a traveling pulse starting from one infectedbird. Numerically, we obtain the percentage of survival in °ock and human afterthe epidemic. We also simulate the minimal portion of immunization in order toprevent further spread.DOI : http://dx.doi.org/10.22342/jims.16.1.30.39-49

THE PARTIAL SUMS OF THE LEAST SQUARES RESIDUALS OF SPATIAL OBSERVATIONS SAMPLED ACCORDING TO A PROBABILITY MEASURE
Authors: Somayasa Wayan
Published: February 2017

A functional central limit theorem for a sequence of partial sums processes of the least squares residuals of a spatial linear regression model in which the observations are sampled according to a probability measure is established. Under mild assumptions to the model, the limit of the sequence of the least squares residual partial sums processes is explicitly derived. It is shown that the limit process which is a function of the Brownian sheet depends on the regression functions and the probability measure under which the design is constructed. Several examples ofthe limit processes when the model is true are presented. Lower and upper bounds for boundary crossing probabilities of signal plus noise models when the noises come from the residual partial sums processes are also investigated.DOI : http://dx.doi.org/10.22342/jims.19.1.127.23-40

CFD investigation of slugging behavior in a gas-solids fluidized bed
Authors: Guan Yanjun , Yao Xiuying , Wu Guiying , Zhang Kai
Published: February 2017

The hydrodynamics of a slugging fluidized bed is investigated numerically by using a two-fluid model suggested by Brandani and Zhang [22]. Numerical simulations are carried out in the platform of a commercial software package, CFX 4.4, by adding user-defined subroutines. The bed expansion ratio, the pressure drop fluctuation and its power spectrum density at the equipment scale and the solids volume fraction distributions at the grid scale are predicted to explore the slugging fluidization characteristics for Geldart group D particles. By comparing with the experimental data in the literature, the numerical model is found to have better predictive ability when the viscous force term is considered in the gas phase momentum equation.

Published: February 2017

Introduction. Jra is a high-frequency antigen belonging to the JR blood group system. Population studies have established that the Jr (a-) phenotype is rare. The clinical significance of anti-Jra antibodies is controversial. This case report describes a newborn with prolonged jaundice due to alloimmunization against Jra antigen. Case Outline. A female Roma infant, 27 days of age, was admitted to hospital due to prolonged jaundice and failure to thrive. Immunohematological testing determined a blood group type A, D+ C+ E+ c+ e+, K-, and the presence of an antibody direct against a high-prevalence red blood cell antigens. On admission, total bilirubin was 199.6 ?mol/l, direct bilirubin 10.3 ?mol/l, hemoglobin concentration 132 g/l, hematocrit 41.1%, reticulocytes 1.08%. The newborn was the third child from a third routinely monitored pregnancy. Maternal sensitization to Jra antigen was detected during the second pregnancy. The titer of anti-Jra reached the highest value of 1,024 at the 28th week of gestation. Conclusion. This is the first description of neonatal hyperbilirubinemia caused by anti-Jra antibody in the Republic of Serbia. This case report provides new data about the clinical significance of anti-Jra in pregnancy and the newborn.

Published: February 2017

Introduction. Human nontuberculous mycobacteria (NTM) or environmental mycobacteria related disease is on increase. Risk factors are unclear and associations are observed in relation to climate differences, population density, or host susceptibility. With availability of molecular techniques for NTM identification, we faced emergence of NTM pulmonary cases. The work is an invitation more to colleagues to enroll the rare NTM cases into large study group. Case report. During an episode of productive cough and fever in a 73-year-old HIV-negative man smoker with minimal sequellae of pulmonary tuberculosis, sputum smears were acid fast bacilli positive on direct microscopy. The L?wenstein- Jensen culture results were positive with 20, 30 and 50 colonies, and molecular identification confirmed Mycobacterium xenopi (M. xenopi). Standard chest radiography showed no signs of active lesions. Examination was completed with bronchoscopy and thorax multi-slice computed tomography (MSCT). Cavitary lesions in the apico-posterior part of the left upper lobe (LUL) were detected. Under treatment (rifampicin, ethambutol, clarithromycin) sputum conversion was achieved, but irregular cavitation in the LUL remained at MSCT after 6 and after 12 months with signs of minimal regression. Patient?s general condition only mildly improved and asthenia remained. Observed risk factors were previous pulmonary disease, tobacco smoking, malnutrition and prolonged emotional stress. Conclusion. M. xenopi related pulmonary disease, difficult to cure and with uncertain prognosis, is a challenge in clinical practice. Since treatment is still controversial, more randomized clinical trials are needed. Current international multicentre approach might be a good option for a larger sample size and development of new guide.

Background/Aim. Non-communicable diseases (NCDs) are a major public health challenge worldwide. Although they are preventable, NCDs are the major global causes of morbidity and mortality, absenteeism, disability and premature death. The aim of this study was to examine socioeconomic inequalities in the prevalence of non-communicable diseases in Serbia. Methods. Data from the 2013 National Health Survey of the population of Serbia was used in this study. There were 13,765 adults interviewed, aged ? 20 years. We used multivariate logistic regression analyses with demographic and socioeconomic determinants of health as independent variables and prevalence of non-communicable diseases as a dependent variable. The minimum level of significance was p < 0.05. Results. Hypertension was the most prevalent NCDs (36.1%). The prevalence of multimorbidity was 47.1%. Multivariate logistic regression analysis showed that gender, age, place of residence, employment status and education were associated with the presence of NCDs. The odds ratio (OR) for age was 1.074 [95% confidence interval (CI) : 1.070?1.077). Women were at a higher risk of NCDs by 58.9% when compared to men (OR = 1.589; 95% 95% CI : 1.467?1.726). Respondents who lived in the rural areas were at a higher risk for NCDs by 14.1% compared to those who lived in urban areas (OR = 1.141; 95% CI : 1.047? 1.244). Odds ratio for unemployment was 1.227 (95% CI: 1.118?1.346). Respondents with primary education were at a higher risk for chronic diseases by 47.1% (OR = 1.471; 95% CI : 1.281?1.687) while those with secondary school were at a higher risk by 27.7% (OR = 1.277; 95% CI : 1.142?1.428) compared to respondents who had higher education. When it comes to Wealth Index, univariate logistic regression analysis showed that respondents who belonged to the poor and middle classes were at a higher risk for NCDs (OR = 2.031; 95% CI : 1.819?2.267; OR = 1.473; 95% CI : 1.343? 1.615) compared to respondents who belonged to the rich class. Multivariate logistic regression analysis did not show statistically significant correlations between the Wealth index and NCDs. Conclusion. Socioeconomic inequalities in health status are the major challenge and should be a target of national health policy in Serbia, not only because they represent social injustice but also because solving the health problems of underprivileged groups of the population can influence improvement of health status of the population as a whole.

La detección oportuna de lesiones causadas por este virus es fundamental para la prevención y tratamiento de dicha enfermedad (Aguilar-Pérez, 2003). Una forma rápida de diagnosticar este tipo de enfermedades se puede lograr mediante el uso de técnicas no invasivas; en este sentido, las imágenes médicas representan la opción más viable, sin embargo, algunas de las desventajas de este método son el bajo contraste y la presencia de ruido, por lo que es importante desarrollar herramientas que contribuyan a la visualización y mejoramiento de las imágenes. El objetivo del presente trabajo es mejorar la capacidad diagnóstica de imágenes médicas producto del procedimiento colposcópico mediante el desarrollo de un software para la visualización, procesamiento y almacenamiento de video e imágenes médicas, específicamente para la detección rápida de lesiones en el tracto genital femenino ocasionadas por el virus del papiloma humano. Se implementaron filtros digitales para mejorar la visualización de dichas lesiones, los cuales incluyen filtrado manual y automático de fluorescencia para imágenes y la detección en tiempo real mediante el procesamiento de video.
Adapting to a Dynamic Higher Education Environment – How the University of Glasgow Library Is Taking Up the Challenge
Authors: Ashworth Susan
Published: February 2017

The University of Glasgow Library is continuously developing space and services to meet the need of students and researchers in an evolving higher education landscape. We are an evidence-based organisation and have used tools such as ethnography, surveys and focus groups to understand how users interact with the physical and virtual library. We have also introduced new roles and created new partnerships across the University, particularly in the context of the United Kingdom Government’s policy on open access and funder requirements for the management of research data. This paper will focus on how the University of Glasgow Library is adapting to both the dynamic scholarly communications environment and the demands of our national research exercise and evidence from users and changing student needs. Every six years in the UK, there is a national research assessment exercise called the Research Excellence Framework (REF) and measurement of the performance of research outputs is a key part of that exercise. From 1st April 2016, in order to be eligible for the next REF, the accepted final version of journal articles and conference proceedings must have been deposited into an institutional repository within three months of the date of acceptance and made open access. Many research funders, such as the Wellcome Trust, also have policies on open access. The Library, in close partnership with the University’s Research Office, has taken the lead in publicising these policies to ensure that researchers are aware of their responsibilities. It has also developed new functionality in Enlighten, our institutional repository service to support compliance. In 2015, the Library commissioned an in-depth ethnographic study to help us more readily understand the changing needs of students and how they use library space. An overview of the results of this work and our next steps will demonstrate how we are “enabling progress”.
Leveraging NISO Standards and Best Practices to Improve Discovery and Access of Digital Resources
Authors: Ma Bie-Hwa , Deng Shi , Xue Susan
Published: February 2017

To tackle issues related to metadata and improve discovery of and access to digital resources, National Information Standards Organization (NISO) has developed a series of standards and recommended best practices. The impact of these standards has been discussed in depth. However, no research has been done in the areas of how those standards and best practices can be used for digital resources in Chinese, and strategies for implementing those standards. This paper aims to identify common issues in discovery of and access to Chinese digital resources; suggest feasible solutions; discuss how to leverage NISO standards and recommended practices; and recommend ways to promote the standards and best practices to stakeholders.

Tutkimuksessa tarkastellaan suonensisäisesti huumeita käyttävien muutosvalmiutta ja siihen liittyviä tekijöitä. Muutosvalmiudella tarkoitetaan itse ilmaistua halua ja valmiutta muuttaa huumeidenkäyttöä, toimia muutokseen eteen ja ottaa vastaan ammattiapua. Aineisto (N=99) on kerätty Kuopiossa sijaitsevassa huumeita suonensisäisesti käyttäville tarkoitetussa Terveysneuvontapiste Portissa. Muutosvalmiutta arvioitiin tätä tutkimusten varten laaditulla mittarilla, joka perustuu muutosmotivaatiota mittaavan DUDIT-E-mittarin muutosvalmiuden itsearviointiosioon. Tutkimuksessa tarkastellaan myös vastaajien elämäntyytyväisyyttä, jota arvioitiin tutkimusta varten muodostetulla elämäntyytyväisyyden summamuuttujalla. Tutkimuksessa verrattiin matalan ja korkean muutosvalmiuden ryhmiä. Tutkimukseen osallistuneiden terveysneuvontapiste Portin asiakkaiden muutosvalmius on korkealla tasolla ja suurin osa vastaajista toivoi huumeiden käyttöönsä muutosta. Muutosvalmiutta ennustivat huumeiden käytön koettu haitallisuus, myönteinen suhtautuminen ammattiapuun sekä työssä käyminen, työkokeilu tai opiskelu. Uskonnollisten yhteisöjen toimintaan osallistuminen oli myös yhteydessä korkeampaan muutosvalmiuteen. Jos potilaan muutosvalmius ja muutosta edistävät tekijät ja niiden merkitys pystyttäisiin tunnistamaan paremmin, Portin tavoin toimivat matalan kynnyksen pisteet voisivat kohdentaa tarkemmin yksilöityä neuvontaa ja ohjausta huumeita suonensisäisesti käyttäville henkilöille.

Observations sur le binôme Ocydromus (Bembidionetolitzkya) fasciolatus Duftschmid - O. (B.) ascendens Daniel (Coléoptères Carabidae Trechinae) dans le sud-est de la France
Authors: Coulon Jacques
Published: February 2017

Les critères distinctifs permettant de séparer Ocydromus (Bembidio-netolitzkya ) ascendens Daniel et Ocydromus (B.) fasciolatus Duftschmid sont étudiés. Ils reposent sur la biométrie pronotale mais surtout sur les genitalia. Pour les femelles un critère inédit portant sur la taille des coxostyles, significativement plus grands chez ascendens est mis en évidence. La répartition en fonction de l'altitude est revue. Il en résulte qu' ascendens est fréquent même en plaine aux environs de Lyon, où les deux espèces cohabitent, que fasciolatus semble absent des très hautes altitudes et est plus commun dans le sud de la région Rhône-Alpes et les départements voisins.

Les colchiques (Colchicum, Colchicaceae) à feuilles hystéranthées du Maroc. 1. Colchicum fharii Fridlender sp. nov
Authors: Fridlender Alain
Published: February 2017

Nous décrivons les principaux caractères qui permettent une étude des colchiques hystéranthés en insistant notamment sur la position relative des stigmates et anthères : caractère biologique (hercogamie) très utile en taxonomie et en floristique. Grâce à l'étude des herbiers et des plantes dans la nature, on montre que C. neapolitanum Ten. est synonyme de C. multiflorum Brot., taxon présent au Maroc, au Portugal, en Espagne, dans le sud de la France, en Italie, en Corse et en Sardaigne. Les C. montanum auct. et C. autumnale var. algeriense Batt. ex Batt. (1902) sont des noms que nous ne retenons pas étant donné que, dès leur création, ils ont été appliqués à plusieurs taxons souvent mal identifiés. Nous décrivons une nouvelle espèce du Moyen Atlas marocain : C. fharii Fridlender. Elle se caractérise par ses grandes fleurs à tépales tessellées, ses feuilles portées par un stipe aérien et ses fruits à carpelles acuminés.

En Méditerranée occidentale, deux espèces à tépales concolores (C. autumnale L. et C. multiflorum Brot.) et deux taxons à tépales tessellés (C. bivonae Guss., C. lusitanum Brot.) sont largement répandus. A ces quatre taxa s'ajoutent les espèces tyrrhéniennes (C. corsicum Baker, C. gonarei Camarda, C. arenasii Fridlender, C. actupii Fridlender), l'endémique marocain C. fharii Fridlender et les taxons du groupe de C. alpinum DC. (C. alpinum subsp. parvulum (Ten.) Nyman. C. alpinum subsp. merenderoides (Perrier et Songeon) Kerguélen) qui ne sont pas véritablement méditerranéens.

Nous esquissons l'histoire hypothétique des espèces méditerranéennes que nous avons regroupés dans trois stirps : bivonae, lusitanum et multiflorum.

Is biomass a reliable estimate of plant fitness?
Authors: Younginger Brett S. , Sirová Dagmara , Cruzan Mitchell B. , Ballhorn Daniel J.
Published: February 2017

The measurement of fitness is critical to biological research. Although the determination of fitness for some organisms may be relatively straightforward under controlled conditions, it is often a difficult or nearly impossible task in nature. Plants are no exception. The potential for long‐distance pollen dispersal, likelihood of multiple reproductive events per inflorescence, varying degrees of reproductive growth in perennials, and asexual reproduction all confound accurate fitness measurements. For these reasons, biomass is frequently used as a proxy for plant fitness. However, the suitability of indirect fitness measurements such as plant size is rarely evaluated. This review outlines the important associations between plant performance, fecundity, and fitness. We make a case for the reliability of biomass as an estimate of fitness when comparing conspecifics of the same age class. We reviewed 170 studies on plant fitness and discuss the metrics commonly employed for fitness estimations. We find that biomass or growth rate are frequently used and often positively associated with fecundity, which in turn suggests greater overall fitness. Our results support the utility of biomass as an appropriate surrogate for fitness under many circumstances, and suggest that additional fitness measures should be reported along with biomass or growth rate whenever possible.
Far Ultraviolet Spectroscopy of Old Novae. II. RR Pic, V533 Her, and DI Lac*
Authors: Sion Edward M. , Godon Patrick , Jones Liam
Published: February 2017

The old novae V533 Her (Nova Her 1963), DI Lac (Nova Lac 1910), and RR Pic (Nova Pic 1891) are in (or near) their quiescent stage, following their nova explosions, and continue to accrete at a high rate in the aftermath of their explosions. They exhibit continua that are steeply rising into the FUV, as well as absorption lines and emission lines of uncertain origin. All three have Far Ultraviolet Spectroscopic Explorer (FUSE) spectra that offer not only higher spectral resolution but also wavelength coverage extending down to the Lyman Limit. For DI Lac, we have matched these FUSE spectra with existing archival International Ultraviolet Explorer spectral coverage to broaden the FUV wavelength coverage. We adopted the newly determined interstellar reddening corrections of Selvelli & Gilmozzi. The dereddened FUV spectra have been modeled with our grids of optically thick accretion disks and hot, NLTE white dwarf (WD) photospheres. The results of our modeling analysis indicate that the hot components in RR Pic and V533 Her are likely to be accretion disks with mass accretion rates of 10−8
M
⊙ yr−1 and 10−9
M
⊙ yr−1 respectively. However, the disk cannot produce the observed absorption lines. For the WD to be the source of the absorption lines in these two systems, it must be very hot, with a radius several times its expected size (because the WD in these systems is massive, it has a smaller radius). For DI Lac, we find the best fit to be a disk with

with a 30,000 K WD.
