Dynamic programming

of each type. Fig. 1: The types of data partitioning A number of researchers have developed different methods to enhance in Cassandra performance and in partitioning strategies of different NoSQL databases: Ata Turk et al [11] proposed data partitioning method based on hypergraph that is constructed to correctly model multi-user operations. This method utilizes the temporal information in prior workloads to try to enhance the Cassandra NoSQL. Abramova et al [19] analyzed the scalability of Cassandra by testing the replication and data partitioning strategies used. Lakshminarayanan [20] proposed an adaptive partitioning scheme for consistent hashing that effect in the heterogeneity of the systems. X. HUANG Et AL [12] proposed a dynamic programming algorithm in the consistent hashing ring based on imbalance coefficient for Cassandra cluster to calculate the position of the new coming node. Wang and Loguinov [21] proposed a greedy algorithm to position the new node in the largest range of the space by splitting the range1 into two pieces. Ramakrishnan, et al. [22] proposed a processing pipeline using the Random Partitioner of Cassandra to allow any non-Java executable make use of the NoSQL and allowing offline processing for Cassandra. Kuhlenkamp et al. [23] benchmarked the scalability and elasticity of Cassandra and HBase. Zhikun et al. [10] proposed a Hybrid Range Consistency Hash (HRCH) partition strategy for NoSQL database to improve the degree of processing and the…

“Earth’s Song” is a two movement suite for piano, violin, and viola. Each movement is inspired by some beautiful aspect of nature, and seeks to paint a picture of nature’s masterpieces through music. The first movement, titled “Morning Lake,” depicts a young couple rowing a boat on a calm lake. The couple sets up their rowboat right before a sunrise. At the very beginning of the movement is a calm, beautiful section, which is meant to depict how peaceful, calming, and relaxing it is to float on…

A traditional computer simply executes a sequence of commands in a single order - like oxen plowing a field. But, according to Blaise Barney of the Lawrence Livermore National Laboratory, parallel computing works by partitioning a problem into multiple tasks which can be done at the same time. For example, your graphics processor may render each section of the screen separately or a signal processing program might apply multiple filters to audio data simultaneously. Think of it as if the…

5. SUMMARY We have derived Laplace's equation for steady-state water flow in two dimensions and have explained how the equation is solved by three Relaxation Methods: Jacobi, Gauss Siedel and Successive Over-Relaxation on a discrete 20 10 grids. The numerical method was illustrated by a Matlab programming code. 6. References [1] John D. Anderson, JR (1995). Computational Fluid Dynamics: The Basics with Applications .McGraw Hill, Inc.

answer, of course, will guide the level of detail required in the model. Finally, a linear programming model should have clarity; i.e. it should be easy to follow and as transparent as possible to a layman. Simulations in general represent a powerful computing technique to analyze manufacturing systems while performing numerical experiments of the models. In case of discrete event simulations the evolution of the system is viewed as a sequence of significant changes in time, also called…

with a business concentration. I have always had an affinity for computers. It seems like on some level they speak to me and I wanted to learn how to speak back in their language. I also am a pretty big gamer and learning how to write and design games is something I have wanted to learn since I was about thirteen years old. Another reason I want to major in computer science is the ongoing proliferation of Internet connected devices and devices with single chip computers in them [1]. There are…

For example, I was a member of ACM University Team in 2010 and I participated in ACM competitions. Also, I was a member of math club and a participant in AUC Mathematics Competition in 2009 where I discussed difficult problems in the field of mathematics. In 2011, I volunteered to teach programming to high school students and I was the coach for a team of 3 students who developed an app using PHP, Flash and MySql to compete in an international competition called Oracle Think-Quest. We received a…

technologies like latest computers, smart phones, search engine algorithms, are done by computer programmers and there writing codes. From last 50 years technologies continue to emerge, develop, and mature at a rapid pace. Now, there are more than 2,500 documented programming languages. So, there are top 10 computer languages timeline. 1). Assembly Language Programs Since the time that the creation of Charles Babbage's distinction motor in 1822, PCs have obliged a method for teaching them…

Django is a free, open source web framework written in the Python programming language and used by millions of programmers every year. Django is a high-level Python web framework that encourages rapid development and clean, pragmatic design. Its popularity is due to its friendliness to both beginners and advanced programmers. Django makes it easier to build better web apps quickly and with less code. Django is robust enough to be used by the largest websites in the world. Django was designed to…

When looking at the group project, I think there were a few areas that I succeed in as far as group dynamics. When it comes to working within a group setting, organization, responsibility, and a dedicated strong work ethic are…
