In this paper, a novel algorithm is developed for the design of minimum-phase FIR filters with sparse impulse responses. Traditional minimum-phase FIR filter design approaches are based on autocorrelation sequences of impulse responses and design problems are formulated as a semidefinite program. To achieve sparse designs, l1 norm of filter coefficients is incorporated in the objective function as...
Multipartite table methods offer a high speed, low area implementation of commonly used functions for up to 24 bits of accuracy. Currently the parameters which dictate the configuration of these tables are chosen using a worst-case rounding approximation scheme which often generates sub-optimal results. This paper will show that it is possible to perform a full exhaustive search to find the minimum...
Content-based image retrieval is a technology that is used to identify similar images based on their visual content. Relevant images are found by employing methods that rank images and show the top-ranked images. One important query pertaining to image retrieval methods is regarding as to how to rank the results. This paper proposes a new method based on an unsupervised Hopfield neural network that...
Memristor is a two-terminal nanodevice that has recently attracted the attention of many researchers due to its simple structure, non-volatility behaviour, high-density integration, and low-power consumption. This paper presents and evaluates a novel binary multiplier composed of memristive devices and nanowire crossbar arrays. Using the proposed multiplier instead of usual digital circuits, the number...
Recent progress in Thermal and infrared Non-Destructive Testing (IRNDT) in different fields have provided interesting defect detection solutions. Principal Component Analysis (PCA) based K-means clustering have been successfully introduced and used in many clustering applications. However, PCA suffers from being relatively more sensitive to the noise due to having a linear transformation. On the other...
Feature fusion methods have been demonstrated to be effective for many computer vision based applications. These methods generally use multiple hand-crafted features. However, in recent days, features extracted through transfer leaning procedures have been proved to be robust than the hand-crafted features in myriad applications, such as object classification and recognition. The transfer learning...
Efficient spectrum sensing is a crucial function in cognitive radio (CR) networks and that enables secondary users (SUs) to detect primary user (PU) activities and make a decision to utilize vacant channels in the spectrum. Cooperative spectrum sensing, which is a prominent sensing approach in the literature due to its ability to increase sensing accuracy, is based on sharing information about channel...
This paper considers the stabilization problem of linear dynamical systems with combined structural properties of symmetry and positivity. Such systems arise in various applications including electromechanical systems, aerodynamics, structural vibration, robotics and compartmental systems, in which the stabilization and performance improvement are the main objectives. Although the goal of the paper...
In this paper, a new on-line observer-based controller is developed to implement trajectory tracking for wheeled non-holonomic mobile robots. The proposed approach is designed to track a user-specified trajectory which is not required to be pre-specified. A novel estimation technique is presented leading to short transient estimation period with reasonable overshoot which are hard to achieve using...
Although static analysis tools detect potential code defects early in the development process, they do not fully support developers in resolving those defects. To accurately and efficiently resolve defects, developers must orchestrate several complex tasks, such as determining whether the defect is a false positive and updating the source code without introducing new defects. Without good defect resolution...
Unmanned systems are increasing in number, while their manning requirements remain the same. To decrease manpower demands, machine learning techniques and autonomy are gaining traction and visibility. One barrier is human perception and understanding of autonomy. Machine learning techniques can result in “black box” algorithms that may yield high fitness, but poor comprehension by operators. However,...
Testing of product is perform to discover or detect the errors and defects in the developed system. But testing is usually time consuming especially when complex projects are canvass. Testing of a product lead off with generation of test cases. The Test case generation are based on three parts coding, design and specification. The Specification based testing deals with generation of test cases from...
In today's world power dissipation is one of the major concern as the complexity of the chip is increasing and more devices are being integrated on a single chip. Thus this high density of chip and increased power dissipation demands for better power optimization methods. Reversible logic is one of the method to reduce power dissipation. Reversible computing has a wide number of applications in areas...
In this paper, experimental results with software defined radios (SDRs) for capturing and localizing WiFi and GSM users are developed. First, a detailed overview on various SDR equipment and software, such as embedded and networked USRPs, WiFi Pineapple, GNU Radio, OpenBTS, and Wireshark is presented. Sufficient details are provided on how to configure and operate the SDR equipment and the associated...
As technology becomes a larger part of everyday life, it becomes increasingly more important for CS and CIT students to learn about cyber security during their education. While many cyber security oriented courses exist, it is also necessary that students must be able to work and learn in an environment that resembles a real world context. To address this problem it has become common to adapt cyber...
This case study is about the introduction of computer science to girls in an all-girl environment. Due to the lack of women in technology, many efforts are being made to expose girls to computer programming at an early age. Code camp organizers are using the all-girl model to help put participants more at ease and boost their computing confidence. High computer self-efficacy leads to studying computer...
In seeking solutions to the engagement of STEM learners, the research community has offered approaches on both the learning technology and STEM pedagogy fronts. These approaches are predominantly being developed in parallel with negligible empirical studies as to the integration of applied learning theory and delivery technology. To compound this challenge there exists the critical component of developing...
In this paper, we present an interdisciplinary undergraduate research project administered in an extracurricular setting as a means to complement student's learning in design-oriented courses and laboratory exercises in electrical engineering. We also examine its effectiveness in improving student learning experience and technical competency. Our design project is conceived in a top-down approach,...
Students of the iSTEM Club at Bridgewater-Raritan High School started the Digital Literacy project in the village of Paushi, West Bengal back in the summer of 2013. Two phases of the project have since been completed, one in 2013 and one in 2014. The first phase consisted of setting up one desktop system and one printer, which were used to teach the children of the village how to use computers. In...
