introduction: in today's world of knowledge with increasing complexity, the need for exchanging data, information, and knowledge is undeniable. electronic health record is undoubtedly a key technology in health care which facilitates the recovery and processing of health information from multiple locations and provide more efficient and more effective treatment for the patient. automatic data t...

Information security is the key in the era of electronic data exchange. Images constitute a large portion of the electronic data. Confidentiality of color images is a difficult process. Most of the image encryption algorithms are complex and compromise on the quality of the image. This paper proposes a new image encryption based on random pixel permutation with the motivation to maintain the qu...

This paper presents a statistical method for deriving optimal spatial sampling schemes. It focuses on ground verification of minerals derived from hyperspectral data. Spectral angle mapper (SAM) and spectral feature fitting (SFF) classification techniques were applied to obtain rule mineral images. The rule images provide weights that are utilized in simulated annealing. A HyMAP 126channel airb...

Information Technology (IT) is the study of systems especially computers for storing, retrieving, and sending information. It uses any networking and other physical devices, infrastructures to secure and exchange all forms of electronic data. IT is used globally as a major portion of daily life and we use it nearly every day within organizations for many reasons. Our computers, mobile phones an...

We present morphologic observations and spectral modeling results of a large, kaolin-group mineral-bearing deposit within Kashira crater in the southern highlands of Mars. We employ both non-linear unmixing of Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) visible to near-infrared (VNIR) reflectance data and linear unmixing of Thermal Emission Spectrometer (TES) thermal infrared (...

Nowadays more and more information is being exchanged electronically. Reasons for this include a higher degree of cooperation between information suppliers and users, an increasing demand for speed (of production and modification, and reduction of time to market), and cost reduction. On the technology side, the advent of the electronic highway enables effective and efficient electronic informat...

In the era of Big Data and Internet Things (IoT), information security has emerged as an essential system application metric. The exchange among ubiquitously connected smart electronic devices requires functioning reliably in harsh environments, which highlights need for securing hardware root trust. this work, by leveraging uniform nonlinear resistive switching emerging electroforming-free ana...
