Abstract

Remote sensing multi-band hyperspectral image classification is a challenging task and is of current interest too. Proper extraction of spectral features of the data results in higher classification accuracy. This paper proposes a hybrid approach to obtain maximum classification accuracy of hyperspectral data. First and foremost, the Fast Fuzzy Cluster Means (FastFCM) algorithm is presented for overcoming the limitation of high computational time of conventional FCM for high-dimensional data. The segmented outcome as spectral information is then combined with the spatial information obtained by the Extended Multiattribute Profiles (EMAPs) to form a composite kernel (filter). In this experiment, the Support Vector Machine (SVM) is used as a classifier to train the data. The classification outcome in terms of three parameters Overall Accuracy (OA), Average Accuracy (AA), and Kappa Index (KI) of the proposed approach (named as (FastFCM-SVM)) has been compared with some current state-of-art methods to investigate its better stability and classification performance.

185. A Block Cipher for Resource-Constrained IoT Devices

Abstract

In the Internet of Things (IoT), many devices are connected and accumulate a sheer amount of data. These Internet-driven raw data need to be transferred securely to the end-users via dependable networks. Consequently, the challenges of IoT security in various IoT domains are paramount. Cryptography is being applied to secure the networks for authentication, confidentiality, data integrity and access control. However, due to the resource constraint properties of IoT devices, the conventional cipher may not be suitable in all IoT networks. This paper designs a robust and effective lightweight cipher to secure the IoT environment and meet the resource-constrained nature of IoT devices. We also propose a symmetric and block-cipher based lightweight cryptographic algorithm. The proposed algorithm increases the complexity of the block cipher, maintaining the lowest computational requirements possible. The proposed algorithm efficiently constructs the key register updating technique, reduces the number of encryption rounds, and adds a layer between the encryption and decryption processes.

189. Performance Evaluation of the Commonly-Used Portable Cholesterol Sensors for Telehealth Services in the Unreached Communities.

Abstract

Portable medical sensors play an important role in healthcare services, especially in rural communities. Many telehealth systems use these devices for providing patients' vital information from a distance to remote doctors. Erroneous data will not only mislead the remote doctor for correct diagnosis but it will cause health threats to these unreached community people. Therefore, it is very important to identify good sensors with an acceptable level of accuracy but within the affordable price of the available sensors in the market. This study aims to identify quality portable cholesterol sensors with high accuracy with the reference of the Japanese clinical pathology laboratory as a gold standard. We have considered cholesterol sensors that measure total cholesterol for this study that are commonly used in the developing countries of Asia. We found that out of four, three of them were very much erroneous and cannot be recommended even for primary healthcare. [ABSTRACT FROM AUTHOR]

190. A Critical Survey on Developed Reconstruction Algorithms for Computed Tomography Imaging from a Limited Number of Projections.

Abstract

Rapid system and hardware development of X-ray computed tomography (CT) technologies has been accompanied by equally exciting advances in image reconstruction algorithms. Of the two reconstruction algorithms, analytical and iterative, iterative reconstruction (IR) algorithms have become a clinically viable option in CT imaging. The first CT scanners in the early 1970s used IR algorithms, but lack of computation power prevented their clinical use. In 2009, the first IR algorithms became commercially available and replaced conventionally established analytical algorithms as filtered back projection. Since then, IR has played a vital role in the field of radiology. Although all available IR algorithms share the common mechanism of artifact reduction and/or potential for radiation dose reduction, the magnitude of these effects depends upon specific IR algorithms. IR reconstructs images by iteratively optimizing an objective function. The objective function typically consists of a data integrity term and a regularization term. Therefore, different regularization priors are used in IR algorithms. This paper will briefly look at the overall evolution of CT image reconstruction and the regularization priors used in IR algorithms. Finally, a discussion is presented based on the reality of various reconstruction methodologies at a glance to find the preferred one. Consequently, we will present anticipation towards future advancements in this domain. [ABSTRACT FROM AUTHOR]

Abstract

An extensive field study was made in subtropical hot humid climate of north-east India to identify the most influencing climatic and human-made environmental factors and their effects on hatchability of eggs and survivability of indigenous ducklings hatched through indigenous broody hen (chicken) managed under a backyard farming system. Hatchability and survivability ratio was estimated from 858 batches duck eggs recorded from 220 marginal/landless duck farmers over a period of 24 months. Statistical analysis by fitting fixed effect general linear models revealed that the ambient temperature and relative humidity were the most critical climatic factors that affect the hatchability ratio of duck eggs and survivability ratio of ducklings. Besides, the human-made factor was also found to be associated with variations of the hatchability and survivability performances of duck under broody hen incubation. Thus identification of these factors and their effects on the studied traits would be helpful to provide appropriate season-based management strategies for economic and sustainable duck production in rural backyard farming systems. The present finding could be a valuable insight for duck farmers not only in north-east India but also in other developing countries with a subtropical hot humid climate with prevailing backyard duck production systems.
