Abstract
Images of outside scenes are typically degraded by the cloudy or opaque medium in the atmosphere. Haze, fog, and smoke in atmosphere are such phenomena because of atmospheric absorption and scattering. Due to the smoke or fog in the atmosphere, the irradiance received by the camera from the scene point is attenuated along the line of sight. Smoke and Fog in images can be distinguished based on their physical appearance and density variations. To distinguish these images, features such as SIFT, HOG, LBP features are extracted and are trained using SVM classification model. Smoke and Fog in images can be tested successfully that the image belongs to which class after training the images.

Abstract
The widespread use of Location Based Systems results in the accumulation of movement trajectory details in a massive scale. These mobility traces are very much useful for the researchers and the developers who needs to develop or invent new mobility management applications or modify the existing ones. But without proper privacy preserving mechanism for the published trajectory details may definitely raises the issue of privacy breach for the user. So before publishing the trajectory details suitable anonymization approach has to be applied. It is also found that the protection of significant points is better than the unnecessary anonymiztion whole trajectory points. This paper proposes a new model, which depicts a model that safeguards the significant points from the malevolent attacks by the help of generalization approach. With this model, the significant location points are hided in a specified size diversified area zone. The analysis shows that this approach is well ahead of the similar approaches used by the researches and provides better privacy and less information loss.

Abstract
The emerging digital era generates heaps of computerized information. The greater part of the electronic data in the world today has been created over the last recent couple of years. The velocity of data generation is unimaginable and incomprehensible. People nowadays are commonly using the digital media to express their stand point about a topic. These opinions are analyzed automatically to know whether the client remark is ideal or not good to the said theme. This ought to be possible by Opinion Mining, also called as Sentiment Analysis. The basic chore in Sentiment Analysis is to categorize the orientation of a given review and subsequently identifying whether the sentiment implied is positive, negative or fair. In this paper, the tweets based on the news thread “Whether National Anthem is needed at Cinema theatres?” are analyzed based on the user rating for the opinions. The classifiers like Bernoulli and Multinomial Naive Bayes, Random Forest, k-Nearest Neighbor (k-NN) and Support Vector Machine (SVM) have been used for analyzing the opinions and found that the Random Forest classifier and Multinomial Naïve Bayes classifier is the top rated classifier based on their accuracy values.

Abstract
With the advancement of technology, there is a rapid growth in e-learning. The use of the Internet in the teaching learning process has made significant impact on both teachers and students. Learners in an e-learning environment have different behavioural patterns, attitudes, aptitudes, learning styles, etc. and the learning resources preferred by these learners also vary. Hence, it is a big challenge for 21st century teachers to deliver the courses in an effective way. One solution to solve this problem is to provide an adaptive form of education. Advantage of this adaptive learning system is that it helps to provide apt material according to the interest and knowledge level of the learners or by understanding the learning facts. An adaptive learning system helps to track students’ knowledge, measure progress and provide solution accordingly. With the support of a suitable Learning Management System (LMS) it is possible to administer, track, report and document the delivery of e-learning courses. In this study, Moodle (Modular Object-Oriented Dynamic Learning Environment) LMS is used for managing every aspect of the course such as course creation, conducting online test, etc. In an e-learning environment, learning content accessed by individual learners will be different and they learn subjects at their own speed and interest. It causes the generation of different learning paths. Hence, the objective of the study is to develop a frame work for an adaptive learning system and identify the learning path of the learners based on their activities recorded in Moodle.

Abstract
The attractions in Big Data Analytics made a progress from relational databases to NoSQL databases. A NoSQL structure can be utilized to enhance the distribution of storage and analysis work of data in the world of big data. MongoDB is a type of NoSQL database which represents data as a collection of documents. Ordinary database systems like MySQL can store only organized data in tabular form as rows and columns. As the majority of the data created now is in unstructured or semi structured format, it is difficult for conventional database systems to store or process this data. NoSQL data stores like MongoDB can store this huge data which additionally have very powerful query engines and indexing features. These features made it simple and fast to execute extensive variety of queries including aggregate ones. The aggregation pipeline and map reduce concepts in MongoDB provides support for aggregate operations. This paper primarily makes a comparison of performance of aggregate queries in MySQL and MongoDB. A set of experiments were performed with two datasets of different size in the two databases. The results show that MongoDB performs better in all the cases. The results can be a boost for companies to change the structure of their databases from conventional form to NoSQL.

Abstract
The huge volumes of data which cannot be manipulated easily by commonly available tools are termed as Big Data. Big Data analytics gives competitive opportunities in designing business plans for Business Analytics. The results are used for taking intelligent business decisions; hence it must be accurate and well-timed. For analytical purpose we use Multiple Linear Regression (MLR) model in the statistical method, a type of Supervised Machine Learning Algorithm. Performance of the particular MLR model with one quantitative dependent attribute and four independent attributes are evaluated using splitting up of the whole data set with Cross-Validation technique. This technique is used to validate the accuracy of model developed from training data with test data to control the problem like over fitting. Here we use Hold-Out Cross Validation method with serial and random partitioning. The data set from UCI machine learning repository are evaluated through simulation methods to check the performance. The model generated in training data are validated with test data, the evaluation shows that the result obtained is a generalized one. The proposed MLR model can be used in the new data set for an accurate result. Here we obtained that the accuracy, measuring with random partitioning is a better method.

Abstract
The importance of analysing moving object data has increased significantly due to the increased acceptance of context aware devices such as Smartphones, GPS connected gadgets etc. Broad use of wireless context aware devices has accelerated the generation of mobility data in various formats.The vital component of moving object data constitutes of geographical coordinates and time. The analysis of space time points in mobility data gives deep knowledge about the movement pattern of the object. Because of the presence of rich semantic aspects in the moving object data, the mining of context related data requires special methods and attention. There are less number of reported works that primarily focuses on the spatial and temporal behavior of moving objects. This research paper concentrate on the methods of extracting Points of Interests from the moving object trajectories by considering its Spatial and Temporal aspects so as to mine useful knowledge from it. Along with the explicit mobility data the method also considers semantic attributes underlined in the travel trajectory.

Abstract
The primary level for the preliminary diagnosis of disease like cancer is the biomedical analysis of microscopic blood sample images. In medical microscopic image analysis, a single image can be evaluated for different types of cells in different phases of maturation. For each cell, the nucleus and cytoplasm might differ in shape, texture, color and density. So it is a challenging problem to automatically segment the cell. In this paper, the various types of white blood segmentation techniques are discussed and the limitations of these methods are also investigated.

Abstract
Emotion recognition is a process by which human emotional states can be identified. Most of the present methods make use of visual and audio information’s together. With recent advancements in deep neural networking, there are several methodologies to identify human emotional states. One of the methods that detect the emotional states is based on a multimodal Deep Convolution Neural Network (DCNN), that use both the audio and visual cues in a deep model. BLSTM-RNN is another method which makes use of multimodal features to capture emotions. A much more efficient approach is using a convolutional neural network (CNN) to extract features from the speech, and for the visual modality, the features can be extracted using a deep residual network of 50 layers. To capture contextual information’s a long short-term memory network can be utilized above these two models. Deep belief networks are another method which takes multimodal emotion recognition into account by first learning the features of the audio and video separately; after which it concatenates these two features. Visual features hold more importance in emotion recognition, so ResNet along with SVR for training can be used to predict emotion states effectively.

Abstract
Ontologies are knowledge representation structures, that models domain knowledge by concepts, instances, rolesand their relationships. Assessment systems can exploit this knowledge by using multiple choice Questions (MCQs). Online assessment systems are mainly using MCQs instead of subjective questions for conducting the tests. Using MCQs for assessments has merits as well as demerits. For assessing wide range of knowledge, MCQs are used. It is because they require very less administrative overhead as well as provide instant feedback to test takers. There are several ontology based MCQ generation approaches proposed by many authors. These approaches generates different kinds of questions, in one approach the stem of all generated question remains the same, another one make use of the semantics of the domain, represented in the form of TBox axioms andABox axioms, to frame interesting MCQs. Some other methods differ in generating distractors for the questions. There are approaches which controls the difficulty level of generated MCQs. This paper gives a literature review and comparison of some of the methods for MCQ generation from ontology.
