Improving Spam Email Filtering Efficiency Using Bayesian Backward Approach Project, M. SHESHIKALA 2020 SREC Engineering College,Warangal

Improving Spam Email Filtering Efficiency Using Bayesian Backward Approach Project, M. Sheshikala

International Journal of Computer Science and Informatics

Unethical e-mail senders bear little or no cost for mass distribution of messages, yet normal e-mail users are forced to spend time and effort in reading undesirable messages from their mailboxes. Due to the rapid increase of electronic mail (or e-mail), several people and companies found it an easy way to distribute a massive amount of undesired messages to a tremendous number of users at a very low cost. These unwanted bulk messages or junk e-mails are called spam messages .Several machine learning approaches have been applied to this problem. In this paper, we explore a new approach based on ...


Integration And Optimization Of A 3d Printed Continuous Flow Reactor In An Inorganic Complexation Reaction, Calli Burnell 2020 State University of New York College at Brockport 81818app手机版下载

Integration And Optimization Of A 3d Printed Continuous Flow Reactor In An Inorganic Complexation Reaction, Calli Burnell

Senior Honors Theses

Current inorganic lab setups do not allow students to use time in lab efficiently and does not allow students to do repeat runs of reactions due to time and material restraints. By implementing a 3D printed continuous flow reactor into the experiment students would be able to redo experiments in class without creating large amounts of waste, all while using a system that was created on campus at a reasonable price. It was found that a mixing chamber with an isobaric design created an environment that allowed complete mixing before reaching a point at which measurements are taken.


Use Of Mathematics In Costume Design And Construction, Ryan DiPaola 2020 State University of New York College at Brockport

Use Of Mathematics In Costume Design And Construction, Ryan Dipaola

Senior Honors Theses

My journey at Brockport did not follow the typical mathematics major’s path; as a student in the adolescent education program, I focused on topics of mathematical literacy, including conceptual understanding, procedural fluency, and mathematical reasoning. As an Honors student, I supplemented my learning experience by contracting courses in stage makeup and costume construction. This thesis combines what I’ve learned across the disciplines, and demonstrates the importance of teaching for mathematical literacy, and the benefits of recognizing underlying mathematical concepts and making informed decisions based on them.


Spectral Properties Of Quaternionic Unit Gain Cycles, Nolan J. Coble 2020 State University of New York College at Brockport

Spectral Properties Of Quaternionic Unit Gain Cycles, Nolan J. Coble

Senior Honors Theses

The quaternions are a non-commutative division ring that extends the complex numbers. A gain graph is a simple graph together with a gain function that assigns a value from an arbitrary group to each edge of the graph. We can define certain concepts on these graphs such as adjacency and Laplacian matrices, gains of paths, and more. If we restrict ourselves to the unit norm quaternions, we can define quaternionic unit gain graphs, or U(H)-gain graphs, as gain graphs where the domain of the gain function is the unit quaternions. Traditional methods from spectral graph theory are not ...

Specifications-Based Grading Reduces Anxiety For Students Of Ordinary Differential Equations, Mel Henriksen, Jakob Kotas, Mami Wentworth 2020 Wentworth Institute of Technology 81818app手机版下载

Specifications-Based Grading Reduces Anxiety For Students Of Ordinary Differential Equations, Mel Henriksen, Jakob Kotas, Mami Wentworth

CODEE Journal

Specifications-based grading (SBG) is an assessment scheme in which student grades are based on demonstrated understanding of known specifications which are tied to course learning outcomes. Typically with SBG, students are given multiple opportunities to demonstrate such understanding. In undergraduate-level introductory ordinary differential equations courses at two institutions, SBG has been found to markedly decrease students’ self-reported anxiety related to the course as compared to traditionally graded courses.

Data Warehousing Applications: An Analytical Tool For Decision Support System, MOHAMMED SHAFEEQ AHMED 2020 Department of Computer Science, Gulbarga University, Gulbarga, Karnataka, India 81818app手机版下载

Data Warehousing Applications: An Analytical Tool For Decision Support System, Mohammed Shafeeq Ahmed

International Journal of Computer Science and Informatics

Data-driven decision support systems, such as data warehouses can serve the requirement of extraction of information from more than one subject area. Data warehouses standardize the data across the organization so as to have a single view of information. Data warehouses (DW) can provide the information required by the decision makers. The data warehouse supports an on-line analytical processing (OLAP), the functional and performance requirements of which are quite different from those of the on-line transaction processing (OLTP) applications traditionally supported by the operational databases. Data warehouses provide on-line analytical processing (OLAP) tools for the interactive analysis of multidimensional data ...

Cloud Computing Applications And Security Issues: An Analytical Survey, Arati Kothari

International Journal of Computer Science and Informatics

Cloud computing, a rapidly developing information technology has becoming a well-known the whole world. Cloud computing is Internet-based computing, whereby shared resources, software and information, are provided to computers and devices on-demand, like the electricity grid. Cloud computing is the product of the fusion of traditional computing technology and network technology like grid computing, distributed computing parallel computing and so on. Companies, such as Amazon, Google, Microsoft and so on, accelerate their paces in developing Cloud Computing systems and enhancing their services to provide for a larger amount of users. However, security and privacy issues present a strong barrier for ...

The Mathematical Analysis Of Column Oriented Database, Amit Kumar Dwivedi, Vijay Kumar Sharma

International Journal of Computer Science and Informatics

81818app手机版下载There are two obvious ways to map a two-dimension relational database table onto a one-dimensional storage interface: store the table row-by-row, or store the table column-by-column. Historically, database system implementations and research have focused on the row-by row data layout, since it performs best on the most common application for database systems: business transactional data processing. However, there are a set of emerging applications for database systems for which the row-by-row layout performs poorly. These applications are more analytical in nature, whose goal is to read through the data to gain new insight and use it to drive decision making ...

Spinning Led Display Using Radio Frequency, Apeksha Sarode, Deepali Madhukar Salunke, Akshaydutta Laxmidutta Shukla, Manvi Mukesh Sonawadekar

International Journal of Computer Science and Informatics

The project consists of Spinning LED display using RF which displays the messages send by the user at the handheld device. if there are no inputs from the user for the system, the message that is programmed in the microcontroller will be displayed continuously. The circuit needs to be mounted on a mechanical structure that rotates at high speed. The display consists of 7 LEDs only in a vertical row. By moving them fast enough, message can be displayed which appears to be generated by a 7*n matrix of LEDs and not a single column of LEDs, where n ...


Linear Feedback Shift Register Based Unique Random Number Generator, HARSH KUMAR VERMA, RAVINDRA KUMAR SINGH 2020 Department of Computer Science and Engineering, Dr. B. R. Ambedkar National Institute of Technology Jalandhar, India

Linear Feedback Shift Register Based Unique Random Number Generator, Harsh Kumar Verma, Ravindra Kumar Singh

International Journal of Computer Science and Informatics

Linear Feedback Shift Register based Unique Random Number Generator is an enhancement of Random Number generator with the additional property that any number generated by a unique random number generator can’t be duplicated. As per users demand for not duplicated random numbers in some applications like transferring a random number over the network on the behalf of actual character of the message for security point of view, existence of unique random number generators are very essential. In this paper LFSR [1] (Linear Feedback Shift Register) is used to implement the proposed concept of unique random number generator. Using LFSR ...
