Higher learning institutions nowadays operate in a more complex and competitive due to a high demand from prospective
students and an emerging increase of universities both public and private. Management of Universities face challenges and concerns of
predicting students’ academic performance in to put mechanisms in place prior enough for their improvement. This research aims at
employing Decision tree and K-means data mining algorithms to model an approach to predict the performance of students in advance
so as to devise mechanisms of alleviating student dropout rates and improve on performance. In Kenya for example, there has been
witnessed an increase student enrolling in universities since the Government started free primary education. Therefore the Government
expects an increased workforce of professionals from these institutions without compromising quality so as to achieve its millennium
development and vision 2030. Backlog of students not finishing their studies in stipulated time due to poor performance is another
issue that can be addressed from the results of this research since predicting student performance in advance will enable University
management to devise ways of assisting weak students and even make more decisions on how to select students for particular courses.
Previous studies have been done Educational Data Mining mostly focusing on factors affecting students’ performance and also used

Predicting students' performance using id3 and c4.5 classification algorithmsIJDKP
An educational institution needs to have an approximate prior knowledge of enrolled students to predict
their performance in future academics. This helps them to identify promising students and also provides
them an opportunity to pay attention to and improve those who would probably get lower grades. As a
solution, we have developed a system which can predict the performance of students from their previous
performances using concepts of data mining techniques under Classification. We have analyzed the data
set containing information about students, such as gender, marks scored in the board examinations of
classes X and XII, marks and rank in entrance examinations and results in first year of the previous batch
of students. By applying the ID3 (Iterative Dichotomiser 3) and C4.5 classification algorithms on this data,
we have predicted the general and individual performance of freshly admitted students in future
examinations.

With the emergence of virtualization and cloud computing technologies, several services are housed on virtualization platform. Virtualization is the technology that many cloud service providers rely on for efficient management and coordination of the resource pool. As essential services are also housed on cloud platform, it is necessary to ensure continuous availability by implementing all necessary measures. Windows Active Directory is one such service that Microsoft developed for Windows domain networks. It is included in Windows Server operating systems as a set of processes and services for authentication and authorization of users and computers in a Windows domain type network. The service is required to run continuously without downtime. As a result, there are chances of accumulation of errors or garbage leading to software aging which in turn may lead to system failure and associated consequences. This results in software aging. In this work, software aging patterns of Windows active directory service is studied. Software aging of active directory needs to be predicted properly so that rejuvenation can be triggered to ensure continuous service delivery. In order to predict the accurate time, a model that uses time series forecasting technique is built.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!

Abstract
Most of students desire to know about their knowledge level to perfect their exams. In learning environment
the fields of study overwhelm on page with collaboration or cooperation. Students can do their exercises
either individually or collaboratively with their peers. The system provides the guidelines for students'
learning system about interest fields as Java in this system. Especially the system feedbacks information
about exam to know their grades without teachers. The participants who answered the exam can discuss
with each others because of sharing e mail and list of them.

1. INTRODUCTION
Thinking of participants is the first step of collaborative learning system. In this step the system
used the student attributes or properties from their profiles. The properties and the values of the
properties are specified by the system. The think step and pair step of the Think-Pair-Share (TPS)
Strategy are measured by the clustering method such as K-means method [1-5].
Data clustering is a data exploration technique that allows objects with similar characteristics to
be grouped together in order to facilitate their further processing. In the system clustering method
is used to produce the groups of student participants according to their properties as shown in
Table 1. The objects are the students and the initial number of cluster is specified with the random
number of students [4], [6].
Cluster analysis is a formal study of methods for understanding and algorithm for learning. K-
mean is the first choice for clustering with an initial number of clusters. K-mean algorithm is
most widely used algorithm in data mining applications. It is a simple, scalable, easily
understandable and can be adopted to deal with high dimensional data. A distance measuring
function is used to measure the similarity among objects, in such a way that more similar objects
have lower dissimilarity value. Several distance measures can be employed for clustering tasks.
The K-Mean algorithm finds partitions with distance measuring function in the cluster which is
minimized [7-9].

2. BACKGROUND THEORY
2.1. Think-Pair-Share (TPS) Strategy
Think-Pair-Share is a relatively low-risk and short collaborative learning technique, and is suited
for instructors and students who are new to collaborative learning.
Think-Pair-Share technique in education is also about:
Think about your answer individually.
Pair with a partner and see your answers.
Share you or your partner’s answer, when called upon.
The purposes of this technique are to process information, having a communication and develop
thinking among students. This strategy helps students become active participants in learning and
can include writing as a way of organizing thoughts generated from discussions [6].
2.2. Think-Pair-Share Technique Role
The teacher decides upon the text to be read and develops the set of questions or prompts that
target key content concepts. The teacher then describes the purpose of the strategy and provides
guidelines for discussions. As with all strategy instruction, teachers should model the procedure
to ensure that students understand how to use the strategy. Teachers should monitor and support
students as they work. In the system the Think-Pair-Share technique will be applied as following:
Thinking: each student thinking of his/her profile attributes and answering the given questions.
Pair: Pair the students’ grade and the K-means clustering result which is used students’ profile.
The students of grades (A-C) will be specified by using his/her exam result.
Share: Share the students’ list that contains not only Grade A and Grade B with their results but
also their email and original group number to communicate each other.
When the system basic level step is finished, both thinking and first part of pairing of the students
who get other Grade can retry the questions next time [3].
2.3. The Main properties of Objects (7 attributes)
The objects of the system are students’ data which are specified by the system. The main
attributes of student information are specified as objects’ properties to calculate the similarity
among objects. The attributes are specified by the collaborative learning system and are
calculated as k-means objects to determine the group of the participants. The attributes and values
of the clustering categories are specified as following Table 1. These all attributes are belonging
to the student objects which are specified by the students’ data of their profile. The system is
defined the students to fill their data which is belong to the following properties and values. The
students’ information and exam results are calculated to apply the TPS theories in this system.

These attributes are specified for the calculation of clustering of the student objects’. There are
three or five clusters to group the students. The students’ attributes are calculated by the
Euclidean distance function to determine the groups of students [11].
2.4. Distance Measuring Function for K-Means Clustering
The system specifies the random objects or students by using Rnd function on attributes. And get
top three or five objects to specify the centroids of initial clusters. Then the system calculates the
members of clusters by using the Euclidean distance function which is shown as following:

Compare Dt with minimize pair value and reassign each object to the cluster to which the object
is the most similar based on the means value of the objects in the cluster (Ct, where t=1, 2,
3,…,k).Update the cluster means; i.e., calculate the mean value of the objects for each cluster
until no change.
2.4.2. Roles of Student Profiles
In the clustering method of the system, the role of students’ profiles is to calculate the groups of
students. The groups of students are specified by the clustering method. Then the students answer
the exam questions which are become the input of next step of the collaborative learning of the
system. The next step is the calculation of paring students according to the result of their exam
marks and their grades. The inputs of the first step are as shown in the following Table 2.

In K-means method, the number of clusters must be specified as the initial clusters’ centroid.
Therefore the example objects are specified from the student profile table as the initial clusters’
centroid are as shown in the following Table 3. The initial cluster centroids are calculated with
other objects in the student profile table by substitution of the Euclidean distance function.

2.6. Pair and Sharing of Participants
The pair and sharing of participants is the final step of the system. The system thinks the
participants’ or students’ skills both calculating the k-mean clustering method and examination
method. The system decides the pair of participants with the grade of advance level students’
marks. Then the system shares the similar upper levels of students’ skill. The students will answer
two steps of exam with their groups. The finally the students are shared among the upper two
levels of groups with their examination information.

Class of Grade Marks
Grade A =8
Grade B 7 4
Grade C 4
In the sharing stage of students, the system gives the students’ information such as email
addresses each other. The students will go on sharing and learning the sense or assuming on the
relative subject with their mail addresses.

4. CONCLUSION
This system aims at the students in order to promote active learning in computer based learning
environment. A well-known collaborative learning technique, the “Think-Pair-Share” is applied
because it has simplicity and suitability to be implemented in a collaborative learning
environment. This system provides the benefits to specify the grades and group of the students by
using K-mean clustering algorithm and also improves the students' learning without difficulties to
find out their interest fields.
