This document summarizes a research paper on using correlation-based feature subset selection to improve spam detection accuracy when using a Bayesian classifier. The researchers introduce using feature subset selection to identify the most relevant features of spam emails while removing redundant features. This improves the accuracy of a naïve Bayesian classifier for spam detection from 65-74% to over 80%. It discusses how correlation-based feature subset selection works by selecting features highly correlated with the class (spam or not spam) but uncorrelated with each other. The researchers apply this method to a spam email dataset and achieve over 92% accuracy in spam detection using a Bayesian network classifier after feature subset selection, an improvement over using the classifier alone.

Nano fillers play a vital role in increasing the performance of different types of motors. In recent days, nano technology
shows a tremendous improvement in the manufacture of high performance electronic devices and circuits, electrical apparatuses and
equipment. In this paper, a wide literature survey was done on the filled of nano dielectrics and nano coated motors. Comparison of
different nano fillers coated motors was done to show which motor was having superior performance characteristics compared to other
motors. Based on the literature survey on the previous research works carried out in the field of applications of nano technology in the
coating of nano fillers to the enamel used in the motors. Ball mills are using three phase induction motors for the mechanical
operations. Ball mills are used to manufacture the nano powders used for both the nano technology and pyro technology. Industries
should be well equipped with safety devices to avoid the fire accidents. Industries should follow the safety norms to avoid the fire
accidents. Pyro technology based research centre was located in Sivakasi to understand and motivate the engineers, people to make an
interest towards Pyro industries and to train the persons about the safety measures while working with the nano pyro powders used in
the nano pyro industries. The powders used here are always in the nano range. But, the people were unaware of this technique. So, this
paper will create some knowledge to the people who are working in nano pyro based industries present in Sivakasi. Sivakasi was an
industrial city located in South India having more than 15000 nano pyro based industries. So, this paper will educate the engineers,
managers and the persons who are all associated with these industries.

A Survey of Existing Mechanisms in Energy-Aware Routing In MANETsEditor IJCATR
A mobile ad hoc network (MANET) is a distributed and Self-organized network. In MANET, network topology
frequently changes because of high mobility nodes. Mobility of nodes and battery energy depletion are two major factors that cause loss
of the discovered routes. battery power depletion causes the nodes to die and loss of the obtained paths and thus affects the network
connectivity. Therefore, a routing protocol for energy efficiency should consider all the aspects to manage the energy consumption in
the network. so introducing an energy aware routing protocol, is one of the most important issues in MANET. This paper reviews some
energy aware routing protocols. The main purpose energy aware protocols are efficiently use of energy, reducing energy consumption
and increasing the network lifetime

Integration of Bayesian Theory and Association Rule Mining in Predicting User...Editor IJCATR
Bayesian theory and association rule mining methods are artificial intelligence techniques that have been used in various
computing fields, especially in machine learning. Internet has been considered as an easy ground for vices like radicalization because
of its diverse nature and ease of information access. These vices could be managed using recommender systems methods which are
used to deliver users’ preference data based on their previous interests and in relation with the community around the user. The
recommender systems are divided into two broad categories, i.e. collaborative systems which considers users which share the same
preferences as the user in question and content-based recommender systems tends to recommend websites similar to those already
liked by the user. Recent research and information from security organs indicate that, online radicalization has been growing at an
alarming rate. The paper reviews in depth what has been carried out in recommender systems and looks at how these methods could be
combined to from a strong system to monitor and manage online menace as a result of radicalization. The relationship between
different websites and the trend from continuous access of these websites forms the basis for probabilistic reasoning in understanding
the users’ behavior. Association rule mining method has been widely used in recommender systems in profiling and generating users’
preferences. To add probabilistic reasoning considering internet magnitude and more so in social media, Bayesian theory is
incorporated. Combination of this two techniques provides better analysis of the results thereby adding reliability and knowledge to the
results.

Comcast announces 2-Gbps Gigabit Pro Internet in Houston [Updated]
1. Comcast announces 2-Gbps Gigabit Pro Internet in Houston
[Updated]
When it launched its 1-gigabit-a-second Internet service last month, ATT finally could claim that it
offered the fastest consumer broadband in Houston.
But those bragging rights are short-lived.
Comcast announced today that it will offer some time this summer a 2-Gbps service, retaking the
speed crown from its rival.
And that's 2-Gbps for both uploads and downloads.
Comcast isn't saying exactly when its new Gigabit Pro service will be available, nor how much it will
cost. The company previously announced the service in Atlanta, California, Chattanooga, Chicago,
Florida and Nashville, but hasn't revealed pricing in those markets yet, either. Comcast has said 18
markets will get Gigabit Pro this year.
Comcast spokesman Michael Bybee said "pricing, including introductory and promotional rates, is
still being considered."
However, the broadband news site DSL Reports spotted earlier this month Comcast Web pages
saying the service would cost $300 a month. When author Karl Bode asked Comcast about them, the
2. pages were yanked.
Gigabit Pro requires that customers live within a third of a mile of the company's fiber network.
Bybee said 1.5 million Houston-area homes will be able to access the service.
But for those who may be disappointed, Comcast also announced immediate availability of a faster
tier that works via its current equipment that uses the DOCSIS 3.0 standard. Extreme 250 boasts
maximum download speeds of 250 megabits a second and costs $149.99 a month. Upload speeds are
25 Mbps.
And the company is currently testing modems that use the updated DOCSIS 3.1 standard that will,
starting next year, make it possible for all Comcast customers to get 1-Gbps service.
As with Comcast's existing Internet offerings, there's no data cap on Gigabit Pro, Bybee said. ATT's
Gigapower has a 1-terabyte data cap, and its standard U-verse DSL service has a 250-gigabyte cap.
In other markets where Comcast has announced the Gigabit Pro service, the company launched yet
another speed bump for existing customers. In Atlanta and California, Comcast increased 50-Mbps
customers to 75 Mbps and 100-Mbps customers to 150 Mbps. Comcast has periodically doubled
speeds for existing customers over the past few years in Houston, but there's no word yet when the
new speed hikes will debut here.
Those who sign up for Gigabit Pro will not be able to use their own cable modems, Bybee said. The
service uses a form of Ethernet to provide the synchronous 2-Gbps service, via a Ciena switch
provided by Comcast and a Netgear R8000 802.11ac router.
Comcast's current service allows customers to bring their own modem and router to the party.
Although this is Comcast's first gigabit-speed residential offering, the company has offered business
customers speeds up to 10 Gbps for some time. Prior to the launch of Extreme 250, the fastest
residential speeds Comcast offered in Houston was 150 Mbps.
In some markets, Comcast has a 505-Mbps service, but it is not available in Houston, Bybee said.
The rise of gigabit consumer Internet speeds kicked off when Google announced it would launch a
gigabit service, starting with Kansas City. The search giant's executives said their ultimate goal was
to goose existing Internet providers to increase their speeds. Google Fiber has since come to other
cities, including Austin, and it typically spurs competitor to boost speeds. For example, Comcast
announced Gigabit Pro in Atlanta shortly after Google said it would offer Google Fiber there.
However, there's no indication that Google Fiber will come to Houston any time soon.
3. Update: I talked about broadband access in Houston on today's episode of Houston Matters on
KUHF FM. You can listen to the segment below.
