Authentication Using Voice Recognition and Timestamp OTP
No full textThis work is related to providing security using authentication. By looking into other research works, we have found many attacks while logging in a system like phishing attack, brute force attack, etc. We came up with a solution which uses voice biometric as a recognition technique and also adding a time stamp one-time password (TOTP) which will help in providing a better authentication during login. Voice recognition technique uses a Bark frequency scale mapped with the input voice signal and made into spectral analysis with cepstral coefficients which is tough to forge, and adding this with TOTP provides stronger security in today’s Internet of Things (IOT)
Increasing High School Student Interest in Science: An Action Research Study
No full textAn action research study was conducted to determine how to increase student interest in learning science and pursuing a STEM career. The study began by exploring 10th-grade student and teacher perceptions of student interest in science in order to design an instructional strategy for stimulating student interest in learning and pursuing science. Data for this study included responses from 270 students to an on-line science survey and interviews with 11 students and eight science teachers. The action research intervention included two iterations of the STEM Career Project. The first iteration introduced four chemistry classes to the intervention. The researcher used student reflections and a post-project survey to determine if the intervention had influence on the students’ interest in pursuing science. The second iteration was completed by three science teachers who had implemented the intervention with their chemistry classes, using student reflections and post-project surveys, as a way to make further procedural refinements and improvements to the intervention and measures. Findings from the exploratory phase of the study suggested students generally had interest in learning science but increasing that interest required including personally relevant applications and laboratory experiences. The intervention included a student-directed learning module in which students investigated three STEM careers and presented information on one of their chosen careers. The STEM Career Project enabled students to explore career possibilities in order to increase their awareness of STEM careers. Findings from the first iteration of the intervention suggested a positive influence on student interest in learning and pursuing science. The second iteration included modifications to the intervention resulting in support for the findings of the first iteration. Results of the second iteration provided modifications that would allow the project to be used for different academic levels. Insights from conducting the action research study provided the researcher with effective ways to make positive changes in her own teaching praxis and the tools used to improve student awareness of STEM career options
Fairness Management: China, Taiwan, Japan, And South Korea
No full textIn this chapter are discussed crucial theoretical underpinnings and critical contextual issues to be considered by successful managers to effectively manage fairness in East Asian countries of China, Taiwan, Japan, and South Korea. Relevant theories from social psychology, marketing, and organizational behavior are introduced to help readers better understand first the current status of fairness management in these countries and secondly how fairness in these countries must be managed in the future. A case on a Chinese customer’s complaint against Mercedes-Benz illustrates the lessons learned
CMOS Technology in Sensing Fields
No full textThe role of CMOS Image Sensors since their birth around the 1960s has been changing a lot. Unlike the past, current CMOS Image Sensors are becoming competitive with regard to Charged Couple Device (CCD) technology. They offer many advantages with respect to CCD, such as lower power consumption, lower voltage operation, on-chip functionality and lower cost. Nevertheless, they are still too noisy and less sensitive than CCDs. Noise and sensitivity are the key-factors to compete with industrial and scientific CCDs. It must be pointed out also that there are several kinds of CMOS Image sensors, each of them to satisfy the huge demand in different areas, such as Digital photography, industrial vision, medical and space applications, electrostatic sensing, automotive, instrumentation and 3D vision systems. In the wake of that, a lot of research has been carried out, focusing on problems to be solved such as sensitivity, noise, power consumption, voltage operation, speed imaging and dynamic range. In this paper, CMOS Image Sensors are reviewed, providing information on the latest advances achieved, their applications, the new challenges and their limitations
Analysis of Emergent Electronic Properties of Self-Assembling Nucleopeptides
No full textBiomolecular structures are held together by a complex network of molecular interactions that direct assembly and stabilize structures. In order to translate the fundamental molecular interactions of biomolecules into the design of functional biomaterials, we have developed a model system that integrates nucleic acids and self- assembling peptides. These nucleopeptides serve as a small-model system for the study of the non-covalent molecular interactions involved in biomolecule self-assembly. We have scaled up and expanded the analysis of our original nucleopeptide library in order to further characterize these assembled structures. Infrared (IR) spectroscopy, Atomic Force Microscopy (AFM), and Transmission Electron Microscopy (TEM) were utilized to characterize the assembly structure and image the supramolecular morphology of the nucleopeptides. The emergent electronic properties of the nucleopeptide assemblies were analyzed by Electrical Impedance Spectroscopy (EIS). Collectively, these studies on nucleopeptide supramolecular structure assembly will contribute to the design of functional biomaterials with the potential to conduct and store electrical charge
The Effects of Sustained Cognitive Dissonance and Perceived Inequity on Employees
No full textThis paper examines the effects of prolonged states of cognitive dissonance and perceptions of workplace inequity on the employee. Anecdotal feedback was collected from employees within an affluent Connecticut school district where there are two main classes of employees – certified and non-certified. The classes are further differentiated by substantial differences in pay structures, in union representation, and in subsequent collective bargaining agreements
Role of Media Publics in the Implementation Of New Technologies
No full textThe use of media publics is an ideal tool for the successful marketing of a technological enterprise. A public can be described as any group or community that affects the level of impact of an organization (Mules, 1998). Media publics plays a major role in creating a perception on how consumers receive a product. Furthermore, the use of media publics give technology firms a platform to reach its intended target. The aim of this poster is to explore the role of the media publics and how it also affects the implementation of new technologies
Organizational Culture: A Business Imperative
No full textAs the personality of an individual can be seen by his or her characteristics and behaviors, the same concept applies to an organization. The characteristics and unique attributes of an organization are depicted by myriad elements, such as its vision/mission statements, beliefs, values, and areas of focus. From such elements, inference regarding the organization’s culture may be made which impacts leadership style, teamwork and collaboration, workflow and processes, innovation, and employee engagement. This literature review is comprised of information and ideas to enable better understanding of the value and importance these components have on an organization’s success, growth, and sustainability
Mechanical Properties of Novel Bionanocomposites
No full textIn the present communication, a study on the synthesis and mechanical properties of a new series of green natural resins based bionanocomposites consisting of acacia, almond, neem and drumstick as resins with nano silica and nanosized calcium oxide as reinforcing fillers has been reported. Mechanical properties such as tensile, shear, adhesive and wear properties were investigated. Present work reveals that mechanical properties such as tensile strength, water resistance and wear resistance of bionanocomposites increases to considerable extent when reinforced with Nano powders of calcium oxide and silicon dioxide. These results are compared with the epoxy resin based nanocomposites. The bionanocomposites have potential to have widespread bioengineering applications
