description: This study seeks to simulate soft tissue behavior with a custom finite element analysis. It is the eventual goal of this team to explore the inverse problem of soft tissues, and this simulation study will play an integral role in that process. It is hoped that new information regarding the elastic properties of soft tissue can be used to diagnose disease processes and improve health care delivery.In this investigation, soft tissue is modeled as a linear, isotropic, elastic, and nearly incompressible material.  A dynamic finite element problem was defined consistent with the experimental protocol of harmonic motion imaging, an elasticity imaging technique that utilizes acoustic radiation force to induce localized displacements within soft tissue samples.The finite element equations of motion in this investigation were solved using the Newmark method, an approach commonly used by engineers to determine the dynamic response of structures under the action of any general time-dependent loads. It was found that the displacement results obtained with the Newmark method made physical sense and agreed with the observations of other researchers in this field, suggesting that the current finite element analysis is a suitable simulation of soft tissue behavior.

Sensitivity analysis for nonlinear structures
Creators: name: Kong, Qiang
Publisher: name: No Publisher Supplied
Year: 2008

description: Sensitivity analysis of total strain energy for nonlinear structures is studied. Based on the law of energy-consistent, the effective strain and stress have been defined to provide scalar measures of the strain and stress for the two and three dimensional problems. The total strain energy is transformed in the form of the effective stain and stress. A closed-form approach for sensitivity calculation is derived. This method can also be extended to large displacement, large rotation problems using the 2nd Piola-Kirchhoff stress and Green-Langrange stress. The numerical examples with both geometric and material nonlinearity are presented to demonstrate the applications for the proposed sensitivity analysis calculation for strain energy. To evaluate the accuracy of the new method, numerical results obtained by the proposed method are compared with those from both analytical solution (for simple geometry) and finite differencing method. The closed-form solution of design sensitivity is also applied for reliability-based structural design. Specifically, the case study is performed for the problem for the uncertain applied force performed, and uncertain Young's modulus with nonlinear materials. The numerical results obtained by the close-formed solution are compared with those from Monte Carlo simulation.
Study of the mechanical properties and the electrical properties of single-walled carbon nanotubes through finite element analysis and molecular dynamic simulations

Publisher: name: No Publisher Supplied
Year: 2008

description: The primary motivation of the current research focuses on the ability to create simplified models that can accurately predict the response of carbon nanotube structures undergoing different types of loading conditions.  Moreover, the conductivity characteristics of these structures under different geometrical arrangements are investigated.  In this way, the mechanical characteristics regarding single-walled carbon nanotubes (SWCNTs) through finite element modeling are computed.  This is followed by the determination of the electrical properties of carbon nanotubes through molecular dynamic simulations.  A simplified finite element model is created for different types of SWCNTs with varying input parameters.  An input array for the elastic modulus and load is generated to control the physical effects of these parameters in the nanotube structure.  The geometries of the nanotubes are altered through various thicknesses employed for the construction of the C--C bonds.  The current work contributes to the generation of different model responses to monitor the stress distribution employing a wide range of parameter values.  The ability to introduce variability in the parameters and boundary conditions without altering the capabilities and computational time in the model represents the main contribution of the thesis from the mechanical component.The electrical aspects of the simulations are carried using simple molecular dynamics schemes taking into consideration finite and infinite SWCNTs modeled as isolated tubes, triangular lattice configurations, and both curved and non-purified structures.  Through optimized molecular models, the total energies of the carbon nanotubes are obtained along with the virtual and occupied energy eigenvalues.  From this analysis, the carbon nanotube band structures can be computed to determine its conductivity capabilities.Findings explaining the output from the mechanical and electrical simulations are summarized.  Furthermore, conceptual contributions for future work are listed to develop  models capable of physically interpreting the characteristics of single-walled carbon nanotubes.

description: Any visitor to Madeira quickly becomes aware of Sir Winston Churchill’s association with the island. The British statesman made a much-publicised visit in 1950, less than a year after Portugal became a founder member of NATO, much to the chagrin of those in the democratic opposition to the Salazar regime who had hoped that the nations which had emerged victorious from the war against fascism would help to bring about a peaceful transition to democracy. Few islanders are aware, however, that another Winston Churchill – an American novelist who was, at one time, even more famous than the politician, chose the island as a setting for his first short story. This article revisits the literary career of the now-forgotten author whose work is still confused with that of his celebrated namesake

description: The overall goal of this research is to identify and understand the factors associated with smoking initiation among AAPI youth. The specific aims of this study are twofold: 1) to identify and explore, using qualitative methodology, the factors associated with youth (age 15-22) smoking onset among two different AAPI groups (Vietnamese and Guamanians); and 2) to develop and pre-test a self-administered survey instrument in order to identify preliminary tobacco use prevalence and patterns, as well as the feasibility and acceptability of the survey for youth in these two communities. The final months of this study will be devoted to survey data analyses and intervention developmentDuring year 1, a program coordinator was hired and the first Scientific and Community Advisory Committee Meeting was held to gather information about current research and provide direction on future research needs. Additionally, a Community Partners Planning Meeting was held with community partners to strategize about focus group and survey activities, and a facilitator training session was conducted to train community members in leading the focus group discussions. In the focus group phase, a total of 10 focus groups were conducted in the Cambodian, Chamorro, and Vietnamese communities involving a total of 57 youth (26 girls and 31 boys) age 13-22 years old. For Cambodians, two groups were held: one with girls of mixed smoking status (n=6), one with boys of mixed smoking status (n=6). For Chamorros, a total of five groups were held: one with nonsmoking girls (n=6), one with nonsmoking boys (n=5), one with both nonsmoking girls and boys (n=2), and two with nonsmoking and smoking girls and boys (n=13). They also conducted a one-to-one interview with a smoking girl. Finally, for Vietnamese, three groups were held: one with nonsmoking girls (n=7), one with nonsmoking boys (n=5), and one with smoking boys (N=6). Following completion of the focus groups, a self-administered survey questionnaire was developed that assessed the following: 1) ethnic identity; 2) demographics; 3) smoking status, history and intention; 4) smoking knowledge and attitudes towards smokers; 5) exposure to marketing; 6) stress; 7) body image and dieting; and 8) participation in leadership activities. The survey was distributed to Chamorro and Vietnamese youth via convenience methodology (e.g., at social events, shopping malls, social clubs, etc.). A total of 200 youth completed the survey, 92 Vietnamese and 108 Chamorro. A final summary report of the findings from the focus groups and surveys was developed and disseminated to all collaborating partners. Dissemination included a news conference that was held on May 18, 2004 to release the findings through ethnic and mainstream media. Additionally, an abstract has been accepted at the upcoming 2004 APHA Annual Conference in Washington, DC.

Hellenistic royal iconography in glyptics
Creators: name: Gross, Robert Allen
Publisher: name: No Publisher Supplied
Year: 2008

description: The present thesis essays to ascertain and research problems that concern the social requirements and the iconography of Hellenistic royal portraiture in glyptics.  Throughout I employ a methodology established by H. Kyrieleis and R. Fleischer that defined anew the study of the numismatic evidence, recognizing in the obverse typology programs of a dynastic iconography.The analysis of the royal iconography is pursued in the second through the fourth chapters, which in their organization take account of the distribution of the material evidence.  Leaving aside the late Ptolemaic dynasty, for which the numismatic evidence remains silent, over two-thirds of the portraits surveyed represent the types of the regnal emissions or are associated with them in iconography.  For the complement of anonymous portraits the I attempt to establish a relative chronology based on correlations educed in the stylistic properties of the obverse types.  Whereas some new attributions are proposed, the arguments are equally directed to an assessment of the stylistic idioms in which the iconography is couched.  I submit that if judiciously applied against the numismatic criteria, this approach can at least suggest the probable dynastic affiliation or regional origin of a given portrait.  The first chapter addresses the social requirements of the glyptic portraiture in the courts.  Principally, it introduces arguments that stand counter to the scholarly consensus.  I mount a case to refute the judgement that portrait cameos may have functioned as the ornamental devices of crowns awarded to the priests attending the eponymous dynastic cults.  The weight of the evidence presumes that medallions fulfilled this purpose.  Further, I would contend that the extended relationship of the glyptic iconography to the obverse types contradicts the theory that the royal house or its commissioners imposed in the aulic environment an iconography of divinized kingship, ideologically separate from that sanctioned for the official, public representation of the dynasty.

Adult medicaid beneficiaries with developmental disabilities and epilepsy: profiles of service use and costs
Creators: name: Knox, Michael
Publisher: name: No Publisher Supplied
Year: 2008

description: Adults with developmental disabilities -- serious chronic impairments that begin in childhood and continue through the lifespan -- are a vulnerable population whose disabilities significantly affect their lives and who typically require lifelong supports (Aday, 1993; Developmental Disabilities Assistance and Bill of Rights Act of 2000, P.L. 106-402). This research analyzed eligibility and claims files of 9,303 community-dwelling adult Medicaid beneficiaries ages 21-64 that were enrolled with the NJ Division of Developmental Disabilities. Using an adapted Behavioral Model for Vulnerable Populations (Gelberg, Andersen, &amp; Leake, 2000) as a conceptual framework, the study identified characteristics associated with epilepsy and addressed the impact of epilepsy on health service use and expenditures. It also identified patterns of epilepsy-related generalist and specialist physician care and examined the association of individual characteristics and patterns of physician care with health care use and expenditures.Adult Medicaid beneficiaries with developmental disabilities and epilepsy were more likely than those without epilepsy to have one or more developmental disability diagnoses other than epilepsy, psychiatric comorbidity, and physical comorbidity. Individuals with epilepsy were more likely than those without epilepsy to have an inpatient admission and to have an emergency room visit. Epilepsy also was associated with higher annual expenditures. Among those with epilepsy, African Americans were less likely than whites to have an epilepsy-related specialist visit. Individuals with Medicare and Medicaid coverage were much less likely to have an epilepsy-related emergency room visit than individuals with Medicaid only.Study results can inform policy makers and practitioners in state developmental disabilities and Medicaid agencies as well as other professionals who assist people with developmental disabilities and their families in accessing medical care.  Access to an appropriate health provider should be a priority of developmental disability case managers, care givers, and residential providers as well as state health care policy makers. The apparent disparity in access to epilepsy-related specialist care also underscores the need for state initiatives to ensure equitable access to care. Moreover, findings regarding comorbidities and increased hospital use by those with epilepsy suggest a need to explore approaches for better management of epilepsy, including coordination between generalist and specialist care.
Numerical simulation of thermal transport in a high hydrostatic pressure food processing vessel
Creators: name: Khurana, Meenakshi
Publisher: name: No Publisher Supplied
Year: 2008

description: High Hydrostatic Pressure Processing (HHPP) is a novel non-thermal food processing technology for producing safe, high quality food products, with minimum detrimental effects of thermal processing such as loss of original flavor and color. The high pressure range used for processing food products is 100 to 1000 MPa. Clams are high pressure processed in the range of 200-350 MPa and fruit juices between 300-600 MPa. Spores, found mainly in low acid foods, and prions need even higher pressures for inactivation.When pressure is applied on a food product using liquid medium, adiabatic heat generation occurs due to compression of the pressurizing medium and the food product, which results in increase in their temperatures. This increase in temperature is different for different foods. For example, water heats up by 2-3°C per 100 MPa increase in pressure. Oils and fats heat more (6-9°C) due to their higher compressibility, lower thermal conductivity, and lower heat capacity. In a high pressure process, the heat generated by adiabatic compression is continuously dissipated to the thick metal wall of the vessel during pressurization and pressure hold stages. The heat loss at the wall and the natural convection flow near the vessel wall give rise to non-uniform temperature distribution within the pressurization medium. Therefore, the objective of this research was to carry out numerical simulation of thermal transport in pressurizing medium (water) during HHPP (at room temperature and higher initial temperature) to predict the temperature distribution. Numerical predictions were validated using experimental data. The impact of the response time of the high pressure thermocouple assembly on the measured transient temperature response was taken into account. Results obtained from the numerical simulation showed that the temperature distribution in the pressurizing medium became non-uniform during the high pressure process and this non-uniformity increased with increasing initial temperatures. Also, increasing the vessel size and inserting an insulating sleeve in the vessel decreased the non-uniformity in temperature. Non-uniformity in temperature in the pressurizing medium can lead to non-uniform microbial inactivation and is of most relevance when a combination of high pressure and high temperature is used to inactivate spores.

Spectrum coordination protocols and algorithms for cognitive radio networks
Creators: name: Jing, Xiangpeng
Publisher: name: No Publisher Supplied
Year: 2008

description: This thesis focuses on the problem of efficiently sharing spectrum resources in wireless networks through the use of appropriate spectrum etiquette protocols and related coordination algorithms. The performance of the proposed class of spectrum etiquette protocols is evaluated in various wireless network scenarios and compared with simpler reactive interference avoidance schemes. After validating its utility for coordination between existing wireless standards (such as IEEE 802.11/WiFi, Bluetooth, and 802.16/WiMax), the spectrum etiquette protocol is extended to serve as the foundation for a more complete adaptive wireless network where radio nodes may cooperate by forming or joining autonomous ad hoc clusters with multi-hop routing. A cognitive radio protocol stack is proposed for this scenario and validated using a combination of ns-2 simulations and experiments on the ORBIT radio grid testbed.The spectrum etiquette protocol proposed here is based on the Common Spectrum Coordination Channel (CSCC) approach which allows explicit coordination for spectrum usage among heterogeneous wireless radio nodes by announcement of their operation parameters such as frequency, power, rate, interference, etiquette policies, etc. An experimental proof-of-concept protocol evaluation is conducted to examine interoperability between WiFi and Bluetooth networks, demonstrating significant performance gains with CSCC as compared to the case with no coordination. Simpler reactive interference avoidance schemes in which radio nodes adjust their transmit parameters such as frequency, power and transmission time based on local observations are also examined in more detail for comparison with CSCC. In particular, we present a detailed comparison between reactive algorithms and proactive CSCC-based etiquette for a co-existence scenario in which both 802.11b and 802.16a operate in the same shared spectrum.With a higher level of spectrum coordination complexity, we examine the ad hoc collaboration scenario in which radio nodes may cooperate with each other to form so-called adaptive wireless networks with multi-hop routing. The CSCC protocol provides a reasonable foundation for this scenario as well by serving as a bootstrapping and resource coordination protocol for radios involved in ad hoc collaboration. Using the CSCC as a base, we propose a complete cognitive radio protocol stack which includes bootstrapping, network/service discovery, cross-layer routing and name/address translation. Each protocol component is validated using a combination of ORBIT experiments and ns-2 simulations.
Sequential analysis of clustered survival data by marginal methods

Year: 2008

description: Clustered survival data are a type of multivariate survival data with naturally formed clusters so that event times within a cluster are parallel to each other and correlated. Lee, Wei and Amato (1992) introduced a semiparametric model for the analysis of clustered survival data that assumes event times follow a proportional hazards model.Sequential analysis of clustered survival data arises in clinical studies in which patients are followed over time and interim analyses are performed. This thesis studies the sequential analysis of clustered survival data with staggered patient entry by adapting Lee, Wei and Amato's approach. It is shown that the two-parameter score process converges to a Gaussian random field irrespective of the correlation within clusters and staggered patient entry. The regression parameter estimator obtained at each time point has the desired properties including consistency and asymptotic normality. A consistent estimator of the baseline cumulative hazard function is also given. More importantly, we propose a novel optimal weighting strategy. We show that the resulting score process not only produces a more efficient estimator, but also has the important property of (asymptotically) independent increments. The latter can be used in conjunction with the well-known error-spending functions to construct proper boundaries in group sequential testing. Finally a sample size calculation formula is given for designing clinicaltrials with clustered survival time as the endpoint.

Purification and characterization of the hydroxylaminobenzoate lyase from pseudomonas pickettii YH105, cloned in escherichia coli
Creators: name: Hunter, Farley Allen
Publisher: name: No Publisher Supplied
Year: 2008

description: The hydroxylaminolyase enzyme of Pseudomonas pickettii YH105 (now Ralstonia pickettii) removed the hydroxylamino group from p-hydroxylaminobenzoate with the concomitant formation of protocatechuate.   In prior work, Brian A. Koller transferred the YH105 gene coding for hydroxyaminolyase into Escherichia coli now identified as BAK100.  Although transferred, the hydroxyaminolyase enzyme was not characterized with respect to protein size and activity.  Utilizing samples of BAK100, the bacteria was grown on Luria-Bertani broth, induced with isopropyl β-D-1-thiogalactopyranoside (IPTG), separated by centrifugation, washed and weighed.  After suspension in morpholinopropane sulfonic acid (MOPS) buffer, the enzyme was released from the crude cells by processing through a French press.  Following centrifugation to remove non-target cell fragments, protamine sulfate treatment was used to remove RNA.  The resulting solution was concentrated and non-target protein removed utilizing ammonium sulfate treatment prior to gradient DEAE and Sepharose 6L-6B gel filtration.  Other purification techniques evaluated and discarded included dialysis, hydroxylapatite treatment, polyethylene glycol precipitation, and pH precipitation.  Overall, the protein was purified relative to the crude cell extract, increasing by a factor of 2.7.  The purification steps resulted in a substantial loss of activity.  The overall yield was only 5%. Several SDS electrophoresis gels all showed multiple prominent bands preventing the determination of enzyme size.  Kinetic studies utilizing HPLC to quantifying protocatechuate formation provided a Km of 0.079 mM and Vmax of 0.16 µmol/min·mg for protamine sulfate treated crude cell extract. Substrates other than p-hydroxylaminobenzoate were tested to evaluate enzyme specificity including m-hydroxylaminobenzoate, 3-methyl-4-hydroxylaminobenzoate and p-hydroxylamino phenyl acetic acid.  Only 3-methyl-4-hydroxylaminobenzoate showed slight conversion, suggesting a high level of enzyme specificity.
An infrastructure for program power behavior characterization and optimization evaluation
Creators: name: Hu, Chunling
Publisher: name: No Publisher Supplied
Year: 2008

description: Fine-grained program power behavior is useful in both evaluating power optimizations and observing power optimization opportunities. Detailed power simulation is time consuming and often inaccurate.  Physical power measurement is faster and objective.  However, fine-grained measurement generates enormous amounts of data in which locating important features is difficult, while coarse-grained measurement sacrifices important detail.This thesis presents a program power behavior characterization infrastructure that identifies program phases, selects a representative interval of execution for each phase, and instruments the program to enable precise and objective power measurement of these intervals to get their time-dependent power behavior. This infrastructure is constituted of three components for instrumentation, phase classification and power measurement, respectively. The Camino compiler, a GCC post-processor, is used to instrument the assembly code of a program on various levels. A phase classification algorithm using infrequent basic blocks and the combination of control-flow information and runtime event counts finds the representative intervals in terms of time-dependent power behavior. These selected intervals accurately characterize the fine-grained time-dependent behavior of the program, as well as accuratelyestimate the total energy consumption of a program. The power measurement method enables users to measure any specified region of program execution. A two-level profiling method implemented in this infrastructure maps the measured detailed power behavior back to source code. The accuracy of this infrastructure is validated on a StrongARM SA110 through simulation, and on an Intel Pentium 4 system through physical power measurement.This thesis also presents the uses of this infrastructure in understanding the power behavior of program components, such as procedures or loops, in finding good threshold for metrics used in dynamic voltage and frequency scaling, and in scheduling simultaneous multi-threaded programs for peak power optimization.

The role of matrix metalloproteinases in zebrafish  (danio rerio) embryogenesis and their regulation by  glucocorticoids

description: Matrix metalloproteinases (MMPs) play a pivotal role during development due to their ability to remodel the extracellular matrix, a function necessary for proper cellular migration and tissue morphogenesis.  Studies have demonstrated that MMP gene expression can be either inhibited or induced by glucocorticoids in a variety of model systems and that exposure to glucocorticoids causes developmental abnormalities in several species.  We hypothesize that glucocorticoid-induced teratogenesis is mediated through the glucocorticoid receptor (GR) and results from altering the expression and activity of the MMPs.  Using the zebrafish (Danio rerio) as a model of development, the data presented here demonstrate that embryonic exposure to the glucocorticoids dexamethasone or hydrocortisone (100 mg/L) increased expression of the gelatinases MMP-2 (~1.5 fold) and MMP-9 (7.6 to 9.0-fold), and the collagenase MMP-13 (2.5 to 4.9-fold) at 72 hours post fertilization (hpf).  In situ hybridization experiments confirmed these increases in MMP expression and demonstrated that the majority of transcript was localized rostrally.  Enzyme activity was also increased at 72 hpf for both MMP-2 and MMP-9 (~3-fold), and MMP-13 (~13-fold) following glucocorticoid treatment, and substrate specificity was confirmed via several MMP inhibitors.  Acute exposure to glucocorticoids resulted in numerous developmental abnormalities, most commonly altered craniofacial morphogenesis.  Morpholino knockdown studies demonstrated that appropriate expression of MMP-2, MMP-9, and MMP-13 are necessary for proper zebrafish embryogenesis since morphants exhibited deleterious alterations in phenotype, and revealed that MMP-2 may compensate for loss of MMP-9 function.  Co-treatment of zebrafish embryos with each glucocorticoid and the GR antagonist RU486 resulted in attenuation of glucocorticoid-induced increases in MMP expression (52-84% decrease) and activity (41-94% decrease), as well as a partial rescue in the abnormal craniofacial phenotypes.  Taken collectively, these data show that dysregulation of MMP-2, MMP-9, and MMP-13 during embryogenesis, whether increased (as with glucocorticoids) or decreased (as with morpholinos), can lead to irregular developmental phenotypes.  The teratogenic effects resulting from prolonged treatment with glucocorticoids may stem from this dysregulation of the MMPs.  Finally, these results suggest that in the embryonic zebrafish, dexamethasone and hydrocortisone function through the GR, and that activation of this receptor can modulate MMP expression.

Globalization and the transformation of citizenship
Creators: name: Gowar, Cheryl
Publisher: name: No Publisher Supplied
Year: 2008

description: This dissertation examines the condition of contemporary citizenship as it is being contested and redefined, with consequences for the prospects for social justice. The study contradicts current theoretical developments that understand the reformulation of citizenship under globalization in terms of expansion and inclusion, by drawing on overwhelming evidence of displacement and disenfranchisement to suggest that citizenship is in demise. While some theorists suggest that waning sovereignty allows new citizenship claims to be made at global and urban scales, my analysis of the practices of the U.S. state shows that it is still thoroughly powerful in constructing the state-subject relationship. Not only does the nation-state serve as the impetus behind, and the mechanism for, differentiation practices that maintain the in/exclusionary quality citizenship, but also the hegemonic U.S. state has expanded its territorial reach to influence the relationship between states and subjects far beyond its own borders. The main body of the dissertation examines in turn the three broad theoretical strands that dominate the globalization/citizenship debate, each positing a new form of citizenship apparently emergent under globalization: postnational, cosmopolitan, and urban. Through examinations of prisoners' rights at Guantánamo Bay and the 'war on terror' conducted in Iraq and Afghanistan I find, respectively, that both the international human rights discourse of postnationalism and the cosmopolitan attempt to generate global democratic institutions are weak in the face of the persistent nation-state. Similarly, the thoroughly attenuated, 'clientalistic' form of citizenship found in contemporary cities, that abandons citizenship to the market as the state retreats from its buffering role, reflects the way in which the nation-state's practices and policies in the context of the global political economy have played out at the urban scale. In all three cases, the new forms of citizenship identified -- empirical and normative -- are overwhelmingly offset by the actions of the nation-state. Rather than accept uncritically an overly optimistic interpretation of the political potential of globalization, I suggest that the nation-state's spatial practices need to be drawn more fully into analyses of contemporary citizenship precisely so that possibilities for oppositional political formation can be evaluated.

Probabilistic distance clustering
Creators: name: Iyigun, Cem
Publisher: name: No Publisher Supplied
Year: 2008

description: We present a new iterative method for probabilistic clustering of data. Given clusters, their centers, and the distances of data points from these centers, the probability of cluster membership at any point is assumed inversely proportional to the distance from (the center of) the cluster in question. This assumption is our working principle.The method is a generalization, to several centers, of the Weiszfeld method for solving the Fermat-Weber location problem. At each iteration, the distances (Euclidean, Mahalanobis, etc.) from the cluster centers are computed for all data points, and the centers are updated as convex combinations of these points, with weights determined by the above principle. Computations stop when the centers stop moving.Progress is monitored by the joint distance function (JDF), a measure of distance from all cluster centers, that evolves during the iterations, and captures the data in its low contours.There are problems where the cluster sizes are given (as in capacitated facility location problems) and there are problems where the cluster sizes are unknowns to be estimated. The probabilistic distance clustering approach works well in both cases. The probabilistic distance clustering method adjusted for cluster size (called PDQ method) method is described, and applied to location problems, and mixtures of distributions, where it is a viable alternative to the EM method.The method is simple, fast (requiring a small number of cheap iterations) and insensitive to outliers.An important issue in clustering is the "right"number of clusters that best fits a data set. The JDF is used successfully to settle this issue and determine the correct number of clusters for a given data set.
