- Genetic, Household and Spatial clustering of Leprosy on an Island in Indonesia: A Population-Based Study
- It is generally accepted that genetic factors play a role in susceptibility to both leprosy per se and leprosy type, but only few studies have tempted to quantify this. Estimating the contribution of genetic factors to clustering of leprosy within families is difficult since these persons often share the same...

- Medical Record Linkage in Health Information Systems by Approximate String Matching and clustering
- Multiplication of data sources within heterogeneous healthcare information systems always results in redundant information, split among multiple databases. The objective in this paper is to detect exact and approximate duplicates within identity records, in order to attain a better quality of information and to permit cross-linkage among stand-alone and clustered...

- General Practitioner Attitudes to the Care of People With Epilepsy: An Examination of clustering Within Practices and Prediction of Patient-Rated Quality of Care
- There is wide variation in the quality of care provided by primary care practices to individuals with chronic illnesses. Individual doctor attitudes and interest have been demonstrated to influence patient outcomes in some instances. Given the trend towards larger practices and part-time working, continuity of care is likely to fall...

- On 5-Axis Freeform Surface Machining Optimization: Vector Field clustering Approach
- A new approach based on vector field clustering for tool path optimization of 5-axis CNC machining is presented in this paper. The strategy of the approach is to produce an efficient tool path with respect to the optimal cutting direction vector field. The optimal cutting direction maximizes the machining strip...

- Large Scale Hierarchical clustering of Protein Sequences
- Searching a biological sequence database with a query sequence looking for homologues has become a routine operation in computational biology. In spite of the high degree of sophistication of currently available search routines it is still virtually impossible to identify quickly and clearly a group of sequences that given query...

- clustering Under the Line Graph Transformation: Application to Reaction Network
- This paper presents the case of metabolic networks where the first network has chemical compounds as nodes and the second one has nodes as reactions. In general, the second network may be related to the first one by a technique called line graph transformation (i.e., edges in an initial network...

- A Novel Fuzzy C-Means clustering Algorithm for Image Thresholding
- Image thresholding has played an important role in image segmentation. This paper presents a novel spatially weighted fuzzy c-means (SWFCM) clustering algorithm for image thresholding. The algorithm is formulated by incorporating the spatial neighborhood information into the standard FCM clustering algorithm. Two improved implementations of the k-nearest neighbor (k-NN) algorithm...

- Czweb: A Web-Based Workspace For Media-Rich Communication
- Despite the ubiquity of the desktop metaphor, the World-Wide Web has resulted in increased interest in browser-based interaction with information. Current browser designs have limited navigational and visualization support and users tend to passively follow links through an ill-understood Webspace. To actively interact with Web-based information, we need a new...

- clustering in Real Estate Prices: Determinants and Consequences
- The article examines the determinants and consequences of price clustering. Real estate list and transaction prices exhibit two price-ending characteristics: even (000-ending) and just-beloweven (900-ending). The use of even-ending prices is negatively related to the precision of the price estimates and the cost of rounding. However, the tendency to use...

- Error-Based clustering and Its Application to Sales Forecasting in Retail Merchandising
- The paper presents an application of error-based clustering to sales forecasting in retail merchandising. It proposes a three-stage methodology. The first two stages estimate the sales parameters (seasonality, price elasticity and product life cycle, for example) using a combination of time series and regression analysis. The third stage pools data...

- Estimation Of NOI Growth, Volatility And clustering By MSA
- In this paper, the creation of metropolitan and property type indices of NOI is examined using repeat sales data from NCREIF. The advantage of creating such indices is that it allows investors and other market participants to understand the general trend in NOI that is often not observable (such as...

- Routability-Driven Packing: Metrics and Algorithms for Cluster-Based FPGAS
- Most of the FPGA's area and delay are due to routing. Considering routability at earlier steps of the CAD flow would both yield better quality and faster design process. This paper discusses the metrics that affect routability in packing logic into clusters. It presents a routability-driven clustering method for cluster-based...

- On the Use of Fuzzy clustering in Construction Simulation
- This paper presents a methodology that integrates fuzzy clustering and computer simulation and demonstrates its use in modeling earthmoving operations. A simulation system (SimEarth) was developed to model earthmoving operations utilizing object-oriented features and discrete event simulation. Fuzzy clustering is used to provide realistic estimates of haulers' travel time so...

- The Spatial clustering of Science and Capital: Accounting for Biotech Firm-Venture Capital Relationships
- This paper focuses on the spatial concentration of two essential factors of production in the commercial field of biotechnology: ideas and money. The location of both research-intensive biotech firms and the venture capital firms that fund biotech is highly clustered in a handful of key U.S. regions. The commercialization of...
