Wireless communication technologies have enabled a kaleidoscopic range of applications that are revolutionizing many aspects of business and public services. Connected cars themselves as new born of new technologies, are the next frontiers for the automobile revolution and the key to the evolution towards the next generation of intelligent transport systems that enable information sharing and communication between vehicles and their internal and external environment. Moreover, connected cars are the main use cases of internet of things (IOT), yet they are the least understood in terms of cyber security. And as with all things using the internet infrastructure for the exchange of information, communications of connected cars are sensitive to various security issues and have some great concerns with privacy and data confidentialities. In this article, we focus on wireless technologies and potential challenges to provide a communication's vehicle-to-vehicle(V2V) or vehicle-to-X(V2X). In particular, we discuss the challenges and review the state-of-the-art wireless solutions for internet of vehicle(IOV). We also identify future research issues for building connected vehicles and solutions which have been proposed by several researchers.

Classification of breast cancer can help in choose the appropriate and the convenient treatment. Many researchers have studied the breast cancer using artificial neural network model (ANN) for his ability to visualize high-dimensional data. The use of learning machine and artificial intelligence techniques has revolutionized the process of diagnosis and prognosis of the breast cancer. However, there are still some problems applying ANN algorithm such as longer training time and lower classification accuracy. To overcome these problems, the SOM model based on Distance travelled by neurons (DSOM) has been proposed, using the Wisconsin diagnostic breast Cancer datasets (WDBC) to distinguish between different types of breast cancer. The data set consists of nine attributes that represent the input layer to the neural network. The neural network will classify the input vectors into two classes of cancer type (benign and malignant). The proposed approach tested on the database, resulted in 97 % succession rate of classification. We can concluded that our approach seems an efficient method to classify in medical applications and especially for the breast cancer classification.

These data is voluminous, various, and difficult to measure and analyze, which appears the concept of Big Data. The vast amount of data makes the ETL (Extract-Transform-Load) process heavy in data warehousing, renders the data mining process more complex, and makes the slow loading of data in database management systems. The solution to make these process more efficient is the use of parallelization technologies, many researchers opt for the use of MapReduce paradigm for its flexibility and powerful. In this paper, we provide an overview of state of the art in MapReduce research and we present its various axis.

Owing to its numerous advantages like high resource elasticity, time improvement, IT maintenance cost reduction, and simplicity, cloud computing paradigm interests many customers. However, notions introduced by the cloud such as the multi-tenancy concept, the computation outsourcing, and the distributed resources increase the security concerns and make trust in cloud providers a critical security challenge. This paper suggests a new method for enhancing the confidentiality of data in the cloud. As data in the cloud has not the same sensitivity, encrypting it with the same algorithms can lead to a lack of security or of resources. The paper proposes to classify data according to a sensitivity level in order to give a suitable security model for each data. By this process, we optimise the use of security mechanisms and the resources consumption.

Cloud computing paradigm attracts different users because of its several benefits such as high resource elasticity, expense reduction, scalability and simplicity which provide significant preserving in terms of investment and work force. However, the new approaches introduced by the cloud, related to computation outsourcing, distributed resources, multi-tenancy concept, high dynamism of the model, data warehousing and the nontransparent style of cloud increase the security and privacy concerns and makes building and handling trust among cloud service providers and consumers a critical security challenge. This paper proposes a new approach to improve security of data in cloud computing. It suggests a classification model to categorize data before being introduced into a suitable encryption system according to the category. Since data in cloud has not the same sensitivity level, encrypting it with the same algorithms can lead to a lack of security or of resources. By this method we try to optimize the resources consumption and the computation cost while ensuring data confidentiality.

It offers numerous advantages both for customers and providers and especially at the cost level that is typically low compared to buying your own resources, configuring and managing them. One of the tremendous services is the data sharing and the data storage. Customers can outsource a huge number of data in cloud without having to worry about the capacity of memory or the size of data as cloud system manage the scalability of servers needed to contains your data. Cloud is flexible, scalable and dynamic so don't worry about capacities. But, one of the predominant concerns encountered in cloud and that can change your mind about this nice view, is security. As more and more sensitive data and personal information placed in the cloud, security concerns grow up. Building trust in providers it is not an easy task with an amount of outages and threats declared since adoption of cloud computing. In this paper, we give a new approach to enhance the security of data outsourced in cloud environment. The approach is based on Cipher Policy-Attribute Based Encryption (CP-ABE) scheme. It consists of encrypting data before outsourcing it and controlling the access to it by encryption. Our method offers scalability, flexibility and fine grained access control of data in cloud. Also, it provides an efficient manner to share confidential data on cloud servers.

In nutshell the web has been transformed from static media to the preferred commu‐ nication media where the user is a key player in the creation of his experiences. The increase in the popularity of social networks on the Web has shaken up tradi‐ tional models in different areas, including learning. Many individuals have resorted to social networking to educate themselves. Such learning is close to natural learning, the learner is autonomous to draw the pathway which best suits his individual needs in order to upgrade his skills. Several training organizations use the Twitter platform to announce the training they provide. We conduct an experiment on twitters data which are related to the training themes in Big Data and Data Science, we perform an exploratory analysis and extract the top group of connected hashtags using the Graph X library provided by the Spark frame‐ work. Data that come from the Twitter platform is produced at high speed and in a complex structure. This leads us to use a distributed infrastructure based on two efficient frameworks Apache Hadoop and Spark. Data ingestion layer is built by combining two frameworks Apache Flume and Kafka.

Video Shot Boundary Detection using the Scale Invariant Feature Transform and RGB Color Channels

In this context, a shot boundary detection algorithm is proposed in this paper based on the scale invariant feature transform (SIFT). The first step of our method consists on a top down search scheme to detect the locations of transitions by comparing the ratio of matched features extracted via SIFT for every RGB channel of video frames. The overview step provides the locations of boundaries. Secondly, a moving average calculation is performed to determine the type of transition. The proposed method can be used for detecting gradual transitions and abrupt changes without requiring any training of the video content in advance. Experiments have been conducted on a multi type video database and show that this algorithm achieves well performances.

The reason is that we need language knowledge to understand the text, and the knowledge itself does not need to be embedded in the text data. Text streams contain very rich semantic information. How to effectively extract information from text is an important component in video content analysis and semantics research. In this paper, a new morphology-based method for text detection in image and video is proposed. It consists of three major stages. In the first stage, the input color image is converted to gray-scale, a morphological binary map is generated by calculating the difference between the closing image and the opening image, and a binarization is performed. In the second stage, candidate regions are connected by using a morphological dilation and erosion operations. In the last stage, the extracted regions are verified based on characteristic of text regions to eliminate non text regions.

Video summarization has been proposed to improve faster browsing of large video collections and more efficient content indexing and access. In this paper, we focus on approaches to video summarization. The video summaries can be generated in many different forms. However, two fundamentals ways to generate summaries are static and dynamic. We present different techniques for each mode in the literature and describe some features used for generating video summaries. We conclude with perspective for further research.
