Magnetic induction tomography (MIT) is a technique used for imaging electromagnetic properties of objects using eddy current effects. The non-linear characteristics had led to more difficulties with its solution especially in dealing with low conductivity imaging materials such as biological tissues. Two methods that could be applied for MIT image processing which is the Generative Adversarial Network (GAN) and the Algebraic Reconstruction Technique (ART). ART is widely used in the industry due to its ability to improve the quality of the reconstructed image at a high scanning speed. GAN is an intelligent method which would be able to carry out the training process. In the GAN method, the MIT principle is used to find the optimum global conductivity distribution and it is described as a training process and later, reconstructed by a generator. The output is an approximate reconstruction of the distribution's internal conductivity image. Then, the results were compared with the previous traditional algorithm, namely the regularization algorithm of BPNN and Tikhonov Regularization method. It turned out that GAN had able to adjust the non-linear relationship between input and output. GAN was also able to solve non-linear problems that cannot be solved in the previous traditional algorithms, namely Back Propagation Neural Network (BPNN) and Tikhonov Regularization method. There are several other intelligent algorithms such as CNN (Convolution Neural Network) and K-NN (K-Nearest Neighbor), but such algorithms have not been able to produce the expected image quality. Thus, further study is still needed for the improvement of the image quality. The expected result in this study is the comparison of these two techniques, namely ART and GAN to get the best results on the image reconstruction using MIT. Thus, it is shown that GAN is a better candidate for this purpose. © 2021 Institute of Physics Publishing. All rights reserved.

Attitudes toward graduate studies are an often overlooked, but potentially important factor in undergraduate engineering students' decisions of whether or not to pursue graduate studies in engineering. Graduate work, especially the Ph.D., requires extensive research, a skill not often emphasized in undergraduate engineering programs. A survey was developed to measure engineering students' attitudes toward graduate studies and examine the reasons students choose to not attend graduate school. The psychometric properties of the survey have been examined and are published elsewhere. The survey has been used to measure the effect(s) undergraduate research programs have on engineering students' attitudes toward graduate studies. Students who participated in the research programs showed increased attitudes from the beginning to the end of their programs and had significantly higher attitudes toward graduate studies than a group of students who did not participate in the programs. Research opportunities for undergraduates have expanded over the past several years with the initiation of federally funded programs such as Research Experiences for Undergraduates (REU) and the Ronald E. McNair Post-baccalaureate Achievement program. During each of the last three years, New Jersey Institute of technology has hosted two separate REUs as well as a McNair program. Data across all three years have been combined to further examine changes in students' attitudes toward graduate studies after participating in one of the programs and to begin investigating possible differences between the students who attended the REU programs and the students who attended the McNair program. Students in the Ronald E. McNair Postbaccalaureate Achievement program showed significantly higher attitudes toward graduate studies, were more positive about research and appeared more likely to pursue careers in academia. © American Society for engineering Education, 2009.

Obstacle removal in crowd evacuation is critical to safety and the evacuation system efficiency. Recently, manyresearchers proposed game theoreticmodels to avoid and remove obstacles for crowd evacuation. Game theoreticalmodels aim to study and analyze the strategic behaviors of individuals within a crowd and their interactionsduring the evacuation. Game theoretical models have some limitations in the context of crowd evacuation. Thesemodels consider a group of individuals as homogeneous objects with the same goals, involve complex mathematicalformulation, and cannot model real-world scenarios such as panic, environmental information, crowds that movedynamically, etc. The proposed work presents a game theoretic model integrating an agent-based model to removethe obstacles from exits. The proposed model considered the parameters named: (1) obstacle size, length, andwidth, (2) removal time, (3) evacuation time, (4) crowd density, (5) obstacle identification, and (6) route *** proposed work conducts various experiments considering different conditions, such as obstacle types, obstacleremoval, and several obstacles. Evaluation results show the proposed model’s effectiveness compared with existingliterature in reducing the overall evacuation time, cell selection, and obstacle removal. The study is potentially usefulfor public safety situations such as emergency evacuations during disasters and calamities.

The nonlinear effects of partial erasure and transition shift, however, often limit the performance attained by the partial response maximum likelihood (PRML) detector because of model mismatch. Conventionally, the nonlinear effects are either ignored or approximated by linearization technique. In the article, a PRML detector for the PR4 model including the nonlinear effects has been developed to improve the detector performance. The new representation is more accurate and the corresponding PRML detector has better performance without increasing the realization complexity. computer simulation results show that the new representation outperforms the conventional ones due to the enhanced modeling capability. The method is also expected to be applied in the high order partial response channel. © 2010 IEEE.

Our department has entered into articulation agreements with several two-year colleges. Subsequently, we have commenced a dialogue with our community college partners as to how we can be more effective and student-centered in our approach to vertical integration. Traditionally, community colleges have done a good job of preparing technicians for industry, but graduates of two-year technical programs have more difficulty in getting appropriate credit for their technical courses. When transferring to a four-year program a direct equivalency is not always possible due to regulatory requirements, but in an outcome-based culture, it should be possible to create supplementary 1-credit or 0-credit courses that make such transfers possible. This paper will detail our initial efforts in that direction. © American Society for engineering Education, 2008.

Uniform scanning model for cognitive communications

Uniform scanning model for cognitive communications

In this paper, in order to capture the spectrum holes with temporal, spatial and frequency variations in sophisticated FHSS radio environments and avoid interference to the existing primary users, a cognitive radio unit (CRU) model with a uniform scanning (U-scanning) technique and cognitive probability ratio (CPR) metric for cognitive communications has been proposed. In this model, real-time spectrum sensing characteristics are coordinated together with system parameters in temporal and frequency domains, e.g., scanning rate and framing processing time, for evaluating the performance of the cognitive radio communications under an elliptic operation scenario. The CPR value is inverse to the hopping rate, and a high CPR value means high spectrum awareness but low coexistence. Moreover, many intriguing numerical results are also illustrated to examine their interrelationships.

Like many institutions across the country, we have embarked on the development of experiences and programs related to the objective of achieving global competence in our engineering students. These internationally-oriented activities have been part of a phased plan at the college level to develop a system to achieve global competence within our graduates that is integrated into their curriculum. This paper presents a description of the current state of the college efforts in this area and provides an overview of future directions towards curricular and non-curricular systems. Emphasis is placed on the integration of the system with academic degree programs within the college and resources outside of the college. Reflections on the experiences and learning gained in the development and implementation of the experiences, programs, and hoped-for college-wide system are presented. These reflections are generalized to be lessonslearned that could apply to other institutions working to build their international programs and to achieve integrating global competence into the curriculum. © 2012 American Society for engineering Education.

Diagnosability is an important parameter to measure the fault tolerance of a multiprocessor system. If we only care about the state of a node, instead of doing the global diagnosis, Hsu and Tan proposed the idea of local diagnosis. Chiang and Tan provided an extended star structure to diagnose a node under comparison model. In this work, we evaluate the local diagnosability better by proposing a tree structure around this node. We provide the corresponding algorithm to diagnose the node. Simulation results are presented for different failure probability of a node in the tree and different percentage of faulty nodes in the tree, showing the performance of our algorithm. © 2024 Institute of Information Science.
