This study is conducted to investigate experts’ views to determine the Omani higher education institutions readiness and deployment of IPv6. In particular, the study aims to assess the institutional awareness, current environment, policy, planning, and resources. Descriptive method was followed and two study instruments were designed and implemente...

During the learning process, whether students remain attentive throughout the session influences their learning capability. If teachers can identify whether students are attentive they can be notified to remain focused, thus resulting in improving their learning capability. Traditional methods require, teachers observe students’ facial expressions...

This paper describes the first stage of an internal grant provided by the Sultan Qaboos University to conduct a research project exploring the actual readiness of Higher Education Institutions (HEIs) to adopt a national migration plan to IPv6. Document analysis was used to derive necessary data on steps taken by the Omani concerned authorities to p...

In this era of information technology, email applications are the foremost and extensively used electronic communication technology. Emails are profusely used to exchange data and information using several frontend applications from various service providers by its users. Currently most of the email clients and service providers now moved to secure...

Outcome Based Education (OBE) or student centered learning is one of the key component in quality assurance and enhancement in the higher education. The OBE approach encourages students to become active learner rather than being passive as in the traditional teacher-centered learning approach. In OBE, teacher is a facilitator of the teaching learni...

Image hashing technique constructs a short sequence from the image to represent its contents. This method proposes an image hash which is generated from Haralick and MOD-LBP features along with luminance and chrominance, which are computed from Zernike moments. Sender generates the hash from image features and attaches it with the image to be sent....

Noise in an image is variation of information from the actual data. If there is any noise in the medical image then consequence will be huge. Physician won't be able to do proper diagnose of the disease and can also affects the quality of post processing techniques like registration and segmentation. Modern techniques use multiple coil MRI(Magnetic...

Modern digital world produces massive amount of data generally refereed as Big Data, which play important roles in dictating the quality of our lives. Relationships among such data have high value, but extremely complex task to establish. Medical Field is one of the major big data sources which produces big volume of data. Modern surgical tools hav...

The medical imaging technology plays a crucial role in visualization and analysis of the human body with unprecedented accuracy and resolution. Analyzing the multimodal for disease-specific information across patients can reveal important similarities between patients, hence their underlying diseases and potential treatments. Classification of MR b...

Alzheimer's disease (AD) is a Dementia among older people which causes neurological degradation. Mild Cognitive Impairment [1] (MCI) is a condition which could progress and then become AD but is not explicitly visible in one's behavior. This paper presents a strategic approach for recognizing MCI at early stage using Magnetic Resonance Imaging (MRI...

Retrieval of similar anatomical structures of brain MR images across patients would help the expert in diagnosis of diseases. In this paper, modified local binary pattern with ternary encoding called modified local ternary pattern (MOD-LTP) is introduced, which is more discriminant and less sensitive to noise in near-uniform regions, to locate slic...

Magnetic Resonance images play a crucial role in the diagnosis and management of the diseases of the brain. The MRI can acquire cross sectional images of our body, based on T1 and T2 relaxation of the tissues. As the information presented in these two images is often complimentary, both these images need to be compared for accurate clinical diagnos...

An intelligent classification technique for MR brain images are extremely important for medical analysis and treatment selection. Manual interpretation of these images by physicians may lead to wrong diagnosis when a large number of MRIs are analyzed. In this paper an automated decision support system for classification is proposed. It consists of...

decision-diagnosis process of brain MR images. For an accurate diagnosis of brain related problems, the experts mostly compares both T1 and T2 weighted images as the information presented in these two images are complementary. In this paper, rotational and translational invariant form of Local binary Pattern (LBP) with additional gray scale informa...

Magnetic resonance images play a vital role in identifying various brain related problems. Some of the diseases of the brain show abnormalities predominately at a particular anatomical location which on MR appears at a slice at defined level. This paper proposes a novel technique to locate desired slice using Rotational, Scaling and Translational (...

Axial brain slices containing similar anatomical structures are retrieved using features derived from the histogram of Local binary pattern (LBP). A rotation invariant description of texture in terms of texture patterns and their strength is obtained with the incorporation of local variance to the LBP, called Modified LBP (MOD-LBP). In this paper,...

Some common fixed point theorems for non-self hybrid mappings have been proved by altering the distance between the points. Our results extends and generalizes many well known results.
