- Abstract
Alzheimer’s disease (AD) is an illness that affects the nervous system, leading to a loss in cognitive and logical abilities. Gene regulatory expressions, which are the complex language exhibited by DNA, serve several functionalities, including the physical and biological life cycle processes in the human body. The gene expression sequence affects the pathology experienced by an individual, its longevity, and potential for a cure. The transcription factors, from DNA to RNA conversion, and the binding process determine the gene expression, which varies for every human organ and disease. This study proposes Deep convolutional neural network model that reads the gene regulatory expression sequence through various convolutional layers encoded to detect positive spikes in transcription factors. This results in the prediction of disease conversion probability from mild cognitive impairment to AD which is the key-requisite for affected geriatric cohorts.

Nowadays, a massive amount of data leads to cause network traffic and inflexible mobility in future mobile networks. A new Group Mobility Model (GMM) named MoMo is introduced that addresses the issue of the aforementioned problems. Even though, software defined network (SDN) is functional with network-rooted mobility protocols that enhance the network efficiency. Some existing network-rooted mobility administration methods still undergo handover delay, packet loss, and high signaling cost through handover processing. In this research work, SDN-based fast handover for GMM is proposed. Here, the neighbor number of evolving node transition probabilities of the mobile node (MN) and their obtainable resource probabilities are estimated. This makes a mathematical framework to decide the preeminent number of the evolving nodes and then allot these to mobile nodes virtually with all associations finished by the exploit of Open-Flow tables. The performance examination demonstrates that the proposed SDN rooted GMM technique has the enhanced performance than the conventional handover process and further technique by handover latency, signaling cost, network throughput, and packet loss.

Difficulty in communicating and interacting with other people are mainly due to the neurological disorder called autism spectrum disorder (ASD) diseases. These diseases can affect the nerves at any stage of the human being in childhood, adolescence, and adulthood. ASD is known as a behavioral disease due to the appearances of symptoms over the first two years that continue until adulthood. Most of the studies prove that the early detection of ASD helps improve the behavioral characteristics of patients with ASD. The detection of ASD is a very challenging task among various researchers. Machine learning (ML) algorithms still act very intelligent by learning the complex data and predicting quality results. In this paper, ensemble ML techniques for the early detection of ASD are proposed. In this detection, the dataset is first processed using three ML algorithms such as sequential minimal optimization with support vector machine, Kohonen self-organizing neural network, and random forest algorithm. The prediction results of these ML algorithms (ensemble) further use the bagging concept called max voting to predict the final result. The accuracy, sensitivity, and specificity of the proposed system are calculated using confusion matrix. The proposed ensemble technique performs better than state-of-the art ML algorithms.

- Abstract
Alzheimer's disease (AD), cerebrovascular disease, Lewy-body disease, and Frontal–temporal degeneration disease are the age-related cognitive impairments that cause dementia. However, AD is the primary cause of dementia that causes brain cell degeneration in the geriatric community. Brain cell degeneration is the crucial cause of AD, due to the abnormal accumulation of indissoluble clumps known as plaques and tangles in the human brain's neurons. Amyloid precursor protein levels and Apolipoprotein -E gene are the biomarkers of AD since it causes accumulations and hence blocks the neuron transport system throughout the body. The early onset of AD includes mild-cognitive impairment (MCI) that progresses to complete dementia. Many related works include AD prediction using clinical modality images and cognitive assessments scores of the individuals but have not addressed comparative genome study for significant subjects. However, there is a lack of affordable biomarkers for the effective early detection of high-risk individuals. In this study, we utilize one or more features of Magnetic Resonance Imaging (MRI) tests and Apolipoprotein-E genotype sequence that provides more significant biomarkers for the early prediction. The ML classifiers including Support vector classifier, Gaussian process, AdaBoost, Random Forest, Decision trees learns the subset of patterns that predicts the AD with gene descriptors from microRNA expression profile and the profiled gene pattern. These significant multiple gene descriptors provide a supportive prediction methodology that apply genotype strength with the ensemble classifiers. The final optimal model is given by validation evaluations. The support vector classifier and Random Forest classifiers had given consistent results for disease conversion and progression from MRI attributes and had given promising results with the validation that showed accuracy greater than 80% and F1 weighted score of 0.8 in disease classification and prognosis. The experimental results had proven 95% accuracy in the saliency values of APOE isoforms implemented in DragonNN framework that will vary AD pathogenic. Hence particular focus and clinical interventions can be given on Aβ genome dependent subjects that predicts the disease.

With the arrival of on-demand computing, data centre requirements are extensive, with fluid boundaries. Loaded Internet applications, service-oriented architectures, virtualization and security provisioning are the major operations of a data centre. Security is an absolute necessity of any network architecture, and the virtual IT data centre is no exception. At the boundary, security is focused on securing the terminals of the data centre from external threats and providing a secure gateway to the Internet. The paradigm shift towards a new computing environment makes communications more complicated for Infrastructure Providers (InP). This complexity includes the security of the data centre's components to protect data from malicious attacks or from being compromised. Threats/attacks are inevitable if the data are generated from a public network, such as Wi-Fi in an Airport, Railway station and other public places. Since these places create enormous amounts of data from anonymous and naive users, it is essential to store the information in a data centre. In this article, we propose an efficient, secure, and privacy-preservation information access algorithm to access data centres in public wifi networks. This algorithm is based on the primitive root approach for sending and receiving credentials through the anonymous authentication of the users and ensuring protected data access from the data centre. Security and Performance Analysis and its evaluation prove that our approach is successful with respect to security, privacy preservation and computational complexity. [ABSTRACT FROM AUTHOR]

8. RETRACTED ARTICLE: The efficient fast-response content-based image retrieval using spark and MapReduce model framework

Hussain, D. Mansoor and Surendran, D.
- Abstract
Content Based Image Retrieval (CBIR) is a way of querying image databases. CBIR looks at visual properties of an image as “search terms” and returns pictures from a database that share the same or almost similar visual properties. Most CBIR systems in the literature works by extracting the image color, texture and shape features before comparing them with those in the database and then compute the distance between features of images for retrieval purposes. In this proposed work, we use a MapReduce model framework to index the large-scale images and Spark has been used as a proportionate method of retrieving the index, which runs on the higher layer of MapReduce and Hadoop distributed file system (HDFS) environment. HDFS provides an in-memory data storage and fast retrieval mechanism using the indexing process. The image retrieval is performed in alignment with the K-Nearest Neighbour’s model using Apache implementation. The processing time has been evaluated with the Hadoop framework in CBIR. The proposed approach takes 10% less time to index images than the distributed image segmentation method discussed in the literature.

Rohini, M. and Surendran, D.
- Abstract
Recently many machine learning and deep learning prediction models have been proposed for the early detection and classification of Alzheimer's disease (AD). AD pathology causes mild cognitive impairment (MCI). The proposed study intends to develop a machine learning model that utilises a relevant subset of predictors to diagnose the progression of the disease. The conversion from MCI to stable MCI (sMCI) or progressive MCI (pMCI) is identified at early stage of onset of symptoms. The quality of existing research works lies in more early identification of disease that greatly affects subjects' recovery. This study utilised mini-mental state exam (MMSE), clinical dementia rating (CDR), estimated total intracranial volume, normalise whole brain volume, and Atlas scaling factor for constructing randomised trees and thus predicting the progression of disease stages from MCI to Alzheimer's disease that causes Dementia. The proposed model proved to give robust classification results that are sufficient for future clinical implementation.

Existing research works for Alzheimer's disease (AD) can predict the prevalence of disease only after the advancement of the disease. With these existing prediction models, it is possible only to reduce and delay the symptoms of the disease. The exact usefulness is when the presence of the disease is identified at an early stage and this early detection makes a great impact in subjects' recovery. Thus, early detection of controls at high risk of development of Alzheimer's disease is of a key objective of the proposed work. Existing machine learning and deep learning algorithms derive only limited predictive accuracy. Also, they derive results based on expensive machine learning algorithms that had hard-to-collect features and classifying becomes complex with numerous overfitting in choosing decision boundaries. The proposed study intends to develop a learning algorithm for the prediction of Alzheimer's disease at an early stage. It also classifies the features if the subjects with Mild Cognitive impairment (MCI) and Pre-Mild Cognitive Impairment (Pre-MCI)has the likelihood to develop Alzheimer's disease. A dataset of AD controls was used to train different machine learning algorithms. Onset information like social behavior, demographic characteristics, neurological test scores, clinical cardiovascular index, and brain atrophy ratio can also be used as the extract predictor. A validation procedure was applied to identify a relevant subset of predictors. The conversion to AD in MCI and Pre MCI subjects are based only on non-invasively and effectively collectible predictors. [ABSTRACT FROM AUTHOR]

With the ageing people community, Alzheimer's disease (AD) is the most common disease in prevalence. It affects the memory of the affected individual by causing neuron degeneration. Such cognitive disability leads people to roam around places since they are ignorant about location. They may go afar from the safe area to traffic prone areas which cause serious, life threatening issues to them. Proposed study introduces a technology that involves a wearable device for Alzheimer disease affected elderly patients and listening device given to care takers or doctors. This system detects and notifies caregivers about the departure of people to risk locations from their residence zone. This system uses Bluetooth Low energy (BLE) communication technology that utilizes transmitter and receiver fixed to elderly individual as wearable device and in residence respectively. Based on the signal strength between the transmitter and receiver, the distance estimation between the elderly and the receiver is calculated with the help of a Raspberry Pi(Rpi) and an alert notification is sent to doctors/caretakers when the distance exceeds safety limit.

Grid Interoperation is a short term solution to join different grid middlewares, which works in the concept of developing bridges/gateways to overcome the dissimilarities of the grid middleware functionalities. Grid interoperability is a long term effort which aims at building standard components pluggable with the native middleware and thereby making it seamlessly connected with other standard middlewares. In this paper, we discuss a grid interoperation mechanism, Extensible Service Based Grid Information Aggregator, which aggregates the resource information from different middlewares viz. GlobusTookit 2.4(GT2), Globus Toolkit 4.0(GT4), UNICORE and gLite. The proposed information aggregator is service based, extensible and pluggable with resource brokers and Meta schedulers. The salient feature in this work is that there is no need for any modifications at the middleware level. The performance of Extensible Service based Grid Information Aggregator (EGSIA) is tested by providing the aggregated resource information to a simulation model which runs deadline driven grid application.

• Feature Selection process perform better selection from UCI heart disease dataset. • ResNet-50 classifier approach is used for secured transmission of heart disease features. • Enhanced ElGamal method for encryption and decryption of data with key generation. • ResNet-50 with near 50 layers classifier for better classification process. • Comparative analysis in terms of performance metrics are performed. Heart disease is increasing, and their detection is a significant concern. With the several technologies developed, the approaches for detection mechanisms can be improved further with better and improved algorithms. Data related with patient's health are of huge amount and stored in the larger space of cloud storage. Accessing cloud storage is an easy task, where the data stored is available to many users of cloud and there comes the need of security. Generally security can be improved using encryption and decryption algorithms. In this paper, a framework using the ResNet-50 classifier approach for secured transmission of heart disease features is performed. This study focused on an enhanced ElGamal encryption-decryption method for the encryption of data with a generated private key and a public key for decryption to better access the data. The data encrypted are then decrypted when the user request data. With Convolutional Neural Network classifier of ResNet-50 with its near 50 layers, the refinement or classification process is performed. The heart disease dataset from the UCI heart disease repository is considered for the evaluation of the proposed work. Further, with feature selection method, better selection of input can be filtered from the selected dataset. The results are obtained with respect to various performance measures, then compared and analyzed with some of the existing methodologies. The results proved to be better than other existing frameworks. [ABSTRACT FROM AUTHOR]

Surendran, D., Purusothaman, T., and Balachandar, R.A.
- Abstract
This paper predicts some of the issues in the next generation grid infrastructure in which islands of grid will try to inter operate each other. The evolution of grid architecture and its related tools motivated many research organisations and institutes to deploy the grid in order to aggregate distributed computing resources to yield high performance computational power. However, these grids are not similar in their implementation as they use different middlewares. Looking ahead, when these grids need to inter operate with each other to form a grid of grids as well as for collaborative research activities between them, there comes a difficulty with respect to interoperability. In this paper, we highlight some of the issues related to interoperability such as aggregation of resource information and job submission across grid of grids. We propose an open, extensible generic interface for aggregating resource information across several middleware such as Globus, gLite and UNICORE. This component has been integrated with a semantic based resource discovery module that discovers suitable grid resources across different middleware based on their semantics. With the experimental analysis the performance of the proposed system is studied.
