Abstract— Genetic Algorithm (GA) is a stochastic randomized blind search and optimization technique based on evolutionary computing that has already been proved to be robust and effective from its outcome in solving problems from variety of application domains. Clustering is a vital technique to extract meaningful and hidden information from the datasets. Clustering techniques have a broad field of application including bioinformatics, image processing and data mining. In order to the find the close

with most extreme number of sensor nodes in each cluster could be accomplished. The weight capacities at every sensor node, which is a blend of various parameters including: residual energy, number of neighbors and transmission control. Basically CFL clustering algorithm is designed for localization in WSNs. It is unable to work when the distribution of sensor nodes are not good. 3.2.4 FoVs: Overlapped Field of View Authors proposed a clustering algorithm for wireless sight and sound sensor networks

(balanced iterative reducing and clustering using hierarchies) is an unsupervised data mining algorithm used to achieve hierarchical clustering over particularly huge data-sets. An advantage of Birch is its capacity to incrementally and dynamically cluster incoming, multi-dimensional metric data points in an effort to generate the best quality clustering for a given set of resources (memory and time constraints). In most cases, Birch only requires a single scan of the database. In addition, Birch is

Malik et al. investigated the impact of different characteristics over the change of code comments. They investigated the likelihood of both header and non-header comment changes over time using Random Forest algorithm [1]. In contrast to their work, we implemented our approach using Regression model and Bootstrap validation technique to perform more comprehensive analysis on the metrics which influence the code change. In their study a variety of metrics are used to predict the likelihood of a comment

categories of research: moving object cluster discovery and trajectory clustering. Moving objects clustering means a group of object travels together where locations are not defined. Trajectory clustering refers a group of locations based on similar objects traveling though traveling time is not considered. Li et al. \cite{li2010swarm}, propose the concept of temporal moving objects swarms, which captures the moving objects move within an arbitrary shape of clusters for certain timestamps that are non

Since hunter-gatherers time, hallucinogens have been known to be used in tribal rituals. Such tribes believed in animism: unusual abilities and prudence can be derived from nature (e.g. plants) and the ‘spirits’ within them. Passing the knowledge down to the coming generations via shamans, whom by experience have mastered handling different hallucinogen containing-plants: to reach an altered state of mind. In the present, it is known that hallucinogens are banned in most parts of the world. However

The approach to assign sample to strata is proportionate stratification which means the sample size of each stratum is proportionate to the population size of the stratum. The sample size for each stratum is determined by Equation 1: Equation 1. nh = (Nh / N) × n where nh is the sample size for stratum h, Nh is the population size for stratum h, N is total population size, and n is total sample size. h = 1 (city of Montreal), 2 (Laval/ North Shore), 3

1. Define sampling. Why do researchers utilize sampling? A. Sampling is a selection of a smaller percentage of individuals from within a larger population that is used to estimate the attitudes and characteristics of the whole population. Sampling saves time and money which is always a good thing, and allows for more manageable research. It may be almost impossible to identify every member of a population/group some may be too large, for example, if you were conducting a study on high school students

The study sample will consist of 1,000 randomly selected patients from randomly selected from the Denver metro area. The Denver metro area includes the following counties: Adams, Arapahoe, Boulder, Clear Creek, Denver, Douglas, Elbert, Gilpin, Jefferson, and Park. The sampling frame is a survey conducted by the patients post-visit with their clinician. On the survey, it will have the same questions to each patient asking if they had utilized information from DTCA information with their physicians

Abstract Data mining can be used to model crime detection problems. Crimes are a social nuisance and cost our society dearly in several ways. Any research that can help in solving crimes faster will pay for itself. About 10% of the criminals commit about 50% of the crimes. Here we look at use of clustering algorithm for a data mining approach to help detect the crimes patterns and speed up the process of solving crime. We will look at k-means clustering with some enhancements to aid in the process
