    ABSTRACT This thesis describes the development of the Arduino based lasso lock security system. It focuses on the security aspects of digital security systems by outlining the common issues. For this project, a microcontroller was chosen, and a test environment was created to experiment with and detect security flaws. The majority of people nowadays are concerned about how to protect their vital and personal things, such as valuables and documents. As a result, the majority of individuals use alarms to secure their lockers at home in order to ensure the safety of their valuables. However, they may still be used through manual lock system procedures without providing any notice to the user when they are broken. This research project develops an enhanced alert system that uses a tension sensor and a numeric keypad to authenticate the user's identity in order to open the lasso-locked box. This project describes a safe and simple security system that utilizes a load cell sensor to handle the locking process. The Arduino, 4x4 keypad, load cell, potentiometer, buzzer and Liquid Crystal Display (LCD) screen are used to hardwire the system. The ARDUINO IDE program was utilized to create the system's controlling statements in the Arduino controller. System testing ensures that a high degree of security is maintained, resulting in optimum performance

    Observations, documents and recordsThe main objective of the research is to replace petroleum-based raw materials with agricultural, bio-based materials for preparation of epoxy cast resins. Epoxy cast resins are polymers containing epoxy or oxirane group that are generally prepared by reacting petroleum-based raw materials with toxic chemicals such as isocyanate. Utilization of alternate resources; i.e., bio-based, agricultural products significantly alleviates health, safety and environmental hazards. Hence, we utilized plant based starting material obtained from soybean oil and orange peel in presence of a Lewis acidic catalyst, tris(pentaflorophenyl)borane or BCF for preparation of epoxy cast resins. Study of various thermal and mechanical properties of the bio-based epoxy cast resins prepared in our lab showed promising results. Major application of these epoxy cast resins includes coatings, adhesives, electrical insulation, 3 D printing, wind turbines, automobile parts, etc

    Value of land is a combination of multiple characteristics of the parcel including water availability, which can greatly affect land sale prices. The objective of this study is to determine the relationship between water availability and land sale prices in Kansas. Within the study region of the 31 westernmost counties in Kansas, the primary source of irrigation for crop production is the Ogallala Aquifer. To this day, depletion rates of the aquifer greatly exceed recharge rates and aquifer water levels continue to steadily decline. As water from the aquifer becomes more scarce, profitability and land values will also decline. A solid understanding of the impact water availability has on land values is imperative to better estimate future land values. Data from the Property Valuation Division (PVD) of the Kansas Department of Revenue (KDR), the Water Information Management and Analysis System (WIMAS), and the Kansas Geological Survey (KGS) were all utilized to determine the relationship between water levels and land values. A hedonic price method was employed to analyze the data. Irrigated parcels have a greater premium compared to dryland operations. In general, a majority of producers in western Kansas are commonly more concerned about having the ability to irrigate rather than the amount water available to irrigate

    Student surveys, peer critiques, faculty focus groupEscape rooms originally developed for entertainment have been modified and used as a didactic tool in teaching and learning (Taraldsen, Haara, Lysne, Jensen, & Jenssen, 2020). Game-based learning offers opportunities related to active learning, creativity, problem solving and social interaction and is well suited for use within nursing education (Taraldsen et al., 2020). Learner centered design theory moves beyond didactic instruction and illustrates alternate modalities of scholarship (Soloway, Guzdian, & Hay, 1994). Escape room scenarios allow graduate nursing students to participate in active learning and creative thinking to transfer the use of acquired knowledge in the clinical setting. In the fall semester of 2021, the Family Nurse Practitioner (FNP) program faculty began the use of escape rooms as an activity during class time. Due to the hybrid format delivery of the FNP program, class time is utilized for accelerated learning experiences. Active learning was evaluated through student surveys. One hundred percent of students achieved a moderate to great gain in knowledge within both types of escape room activities. All FNP students believed educational objectives were met. The goal of this poster is to increase awareness of escape room use within graduate nursing education and to report data collected during use in fall, 2021

    Data obtained through simulations/programsThere are different types of security attacks that are more common now in the technology world. Data gets exchanged all the time and passes through diverse channels that challenges the scientists with efficient ways of protecting them from the hackers. One specific application area that is highly vulnerable to such cyber-attacks in recent days is the electrical energy infrastructures. Securing such infrastructures from these cyber-attacks is very critical and challenging. In this research effort, one such energy infrastructure called the micro grid will be taken into study and analyzed for protecting them against different types of cyber threats. As per the National Institute of Standards and Technology (NIST) guidelines, cyber-attacks are classified into three levels: attacks compromising availability, confidentiality and integrity. In this project, these three levels of attacks on micro grid network will be studied thoroughly. Looking at a typical micro grid infrastructure, the vulnerable points are the distributed energy resources, the micro grid controller, and the communication network which facilitates data exchange between the individual micro grid components. Each of these vulnerable areas will be taken into study and analyzed for proposing different ways to build smart resilient cyber secure micro girds. Following are three important phases involved in this research project.1. Study the different times of cyber-attacks (availability, confidentiality, integrity) on micro grids, 2. Analyze the after effects of such cyber-attacks on these micro grids, 3. Looking into different ways of building smart resilient cyber secure micro grids. The concept of machine learning will be involved to build systems that can learn from the different types of vulnerabilities, take own decisions to prevent the attacks, and self-heal or reverse back to their original state that they existed before the attacks was made. This multi-disciplinary research of building such smart resilient cyber to secure micro grids will unfold a lot of challenges involved in each of the different phases mentioned above

    Following discovery of acute bovine respiratory syncytial virus (BRSV) infection enhancing Histophilus somni (H. somni) clinical disease in calves, further understanding of the safety and efficiency of live-attenuated BRSV vaccines is important. Our objective was to determine the safety, efficiency and immunomodulation of an intranasal (IN), trivalent (infectious bovine rhinotracheitis virus [IBRV], parainfluenza-3 virus [PI3V], and BRSV) respiratory vaccine with parenteral, bivalent bovine viral diarrhea virus (BVDV) and a parenteral, pentavalent (BVDV type I and II, IBRV, BRSV, and PI3V) respiratory vaccine. High-risk beef calves (n=525) were received in 5 truckload blocks and stratified by body weight (213 ± 18.4 kg), sex, and presence of a pre-existing ranch ear-tag. Pens were spatially arranged in sets of 3 and randomly assigned to treatment with an empty pen between treatment groups. Treatments included: 1) no viral respiratory vaccination (CON), 2) cattle intranasally administered a trivalent, modified-live virus (MLV) respiratory vaccine with parenteral BVDV type I and II vaccine (INT), and 3) cattle administered a pentavalent, MLV respiratory vaccine (INJ). Pen was the experimental unit, with a total of 15 pens per treatment and 11 or 12 calves per pen in this 70-d receiving study. Performance, morbidity, mortality, BRSV, H. somni, Mycoplasma bovis (M. bovis), Mannheimia haemolytica (M. haemolytica), and Pasteurella multocida (P. multocida) prevalence and cycle time in nasal swabs via rtPCR on d 0, 7, 14, and 28 was determined, and BRSV-specific antibody titer and serum IFN-γ concentration via ELISA were evaluated on d 0, 14, 28, 42, 56, and 70. Morbidity (P = 0.83), mortality (P = 0.68) and average daily gain (P ≥ 0.82) did not differ; however, feed efficiency from d 0 to 56 was improved (P = 0.05) for CON. Serum antibody against BRSV increased with time (P < 0.01), and was numerically greatest for INT. There was a treatment × time interaction (P < 0.01) for H. somni present in nasal swabs; on d 14 and 28, INT (21.1 and 57.1%) more frequently (P < 0.01) became H. somni positive than CON (3.6 and 25.3%) or INJ (3.4 and 8.4%). Also, INT had reduced (P = 0.03) cycle time of H. somni positive samples on d 28. There was a tendancy (P = 0.06) for a treatment effect for BRSV cycle time; CON had a reduced mean (30.80) than INT (33.53) and (32.93). No treatment × day interaction (P ≥ 0.17) existed for M. bovis, M. haemolytica, or P. multocida prevalence and cycle time. No treatment differences (P = 0.55) were detected for serum IFN-γ concentration. There was a treatment effect (P < 0.01) for the rate of M. haemolytica positive culture from lung tissue specimens; INT had less (0.0%) M. haemolytica positive lung tissue cultures than INJ (45.5%) or CON (74.0%). These data indicate MLV vaccination of high-risk calves, either parenterally or intranasally, did not clearly impact health or growth during the feedlot receiving period. However, INT caused increased prevalence of H. somni in the naris and resulted in less M. haemolytica cultured from lung tissue samples upon necropsy. The intranasal administration of MLV vaccines may alter the microbial community in the upper respiratory tract of cattle; specifically, we observed that MLV IN increased the prevalence of H. somni in high-risk feedlot calves

    A STUDY OF ENGINEERING STUDENTS COLLABORATIVE PROJECT DEVELOPMENT SKILLS IN THE UNDERGRADUATE ENGINEERING CURRICULUM

    No full text
    In recent years, there has been a rapid increase in the use of technologies by educational institutions and students. Use of technologies for educational purpose have taken different dimensions to improve student learning and success. More specifically, engineering education focusses on methodologies that aid development of Industry4.0 skills in students. Engineering design and manufacturing industries are shifting more towards computational tools and are operating in a global sector. With this shift, students should learn to integrate their technical skills with computer skills and also learn to work in a collaborative environment. The use of software tools to aid teamwork and effectively carry out group projects are becoming integral part of engineering curriculum. Due to factors such as conflicting schedules, geographic separation, different learning styles, and different backgrounds, students have always struggled working on group projects. Establishing strong communication channels and thereby building strong teams to work on group projects has been a challenge for faculty members and instructors teaching those courses. Recent technologies have led to the invention of virtual communication that can be enabled through online collaboration tools. These online collaboration tools help students build a working model of working towards the successful completion of their projects. This thesis conducts a state of art analysis of how present day engineering education addresses the computational needs and incorporates Industry 4.0 skills. A conceptual study on the use and impact of computational tools and the use of online collaboration tools in the engineering education was studied. Students and Instructors from different engineering and computer science students were administered in the study and the data obtained from the research was analyzed

    No full text
    Torque MagnetometryThis work presents the Fermi surface studies of the topological crystalline insulators, SnxPb1-xTe/Se with Sn doping using torque magnetometry. The torque signal measured at higher magnetic fields up to 35 T show clear de Haas-van Alphen (dHvA) oscillations. The dHvA oscillations are well-defined and consists of three major frequencies (19 T, 51 T, and 225 T) for the x = 0.35 Se sample, one major frequency (53 T) in the x = 0.4 Te sample, and one major frequency (240 T) for the x = 0.2 Te sample. To better understand the Fermi surface properties, we rotated the samples with respect to the applied field direction and measured dHvA oscillations at different tilt angles. We will present analyses of temperature dependent dHvA data using the Lifshitz-Kosevich (LK) formula and Berry phase calculations

    The future of agriculture will be determined by the ability of post-secondary institutions recruitment of non-traditional agricultural students to agricultural degrees. Only 1.3% of the U. S. population holds direct on-farm employment. As the population slowly becomes disconnected from traditional agricultural lifestyles, the challenge will be identifying new types of students to pursue agricultural degrees. This study determined influential factors experienced by non-traditional agricultural students during decisions to enroll in the Department of Agricultural Sciences at West Texas A&M University. Participants in this study had no knowledge or experience in agriculture prior to enrollment in a post-secondary agricultural department. Factors contributing to enrollment in an agricultural degree include support from significant persons, friendly faculty and staff, hands-on learning experiences, and career opportunities in agricultural sectors. Participants recommended recruitment efforts target inclusivity of non-traditional students by highlighting potential agricultural careers and resources available to non-traditional students. Implications from this study suggest recruitment materials and messages be revisited to promote diversity and inclusion in agricultural degrees
