Integral zeroes of Krawtchouk polynomials

This thesis was submitted for the degree of Master of Philosophy and awarded by Brunel University.Krawtchouk polynomials appear in many various areas of mathematics starting from discrete mathematics (e.g., in coding theory), association schemes, and in the theory of graph representations. The existence/non-existence of integral zeroes of these polynomials is crucial for the existence/non-existence of combinatorial structures in the Hamming association schemes. The integer zeroes of Krawtchouk polynomials for k = 4; 5; 6 and 7 have been found using some very recent results on solvability of polynomial diophantine equations. Our aim is two-fold: Firstly, to verify these results using extensive computer calculations. This requires the solution of some of Pell’s equations and the use of the symbolic mathematics software mathematica. Secondly, we numerically investigate a conjecture dealing with the integer zeroes of the Krawtchouk polynomials Pm2 (m^2) (x) and provide confirmation of the conjecture using a combination of approaches up to m <= 1000, i.e., for the polynomials up to degree of about half a million

On the Integer Zeros of Krawtchouk Polynomials of Degree 8

Krawtchouk polynomials plays very important role in many different areas of mathematics such as discrete mathematics, coding theory, association schemes and graph theory. The issue of existence of integer zeros of Krawtchouk polynomials is crucial for the existence of combinatorial structures in the Hamming schemes. In this Paper our goal is to investigate the integer zeros of the modified Krawtchouk polynomials of the 8th order

Adaptive Control of IoT/M2M Devices in Smart Buildings using Heterogeneous Wireless Networks

With the rapid development of wireless communication technology, the Internet of Things (IoT) and Machine-to-Machine (M2M) are becoming essential for many applications. One of the most emblematic IoT/M2M applications is smart buildings. The current Building Automation Systems (BAS) are limited by many factors, including the lack of integration of IoT and M2M technologies, unfriendly user interfacing, and the lack of a convergent solution. Therefore, this paper proposes a better approach of using heterogeneous wireless networks consisting of Wireless Sensor Networks (WSNs) and Mobile Cellular Networks (MCNs) for IoT/M2M smart building systems. One of the most significant outcomes of this research is to provide accurate readings to the server, and very low latency, through which users can easily control and monitor remotely the proposed system that consists of several innovative services, namely smart parking, garden irrigation automation, intrusion alarm, smart door, fire and gas detection, smart lighting, smart medication reminder, and indoor air quality monitoring. All these services are designed and implemented to control and monitor from afar the building via our free mobile application named Raniso which is a local server that allows remote control of the building. This IoT/M2M smart building system is customizable to meet the needs of users, improving safety and quality of life while reducing energy consumption. Additionally, it helps prevent the loss of resources and human lives by detecting and managing risks.Comment: Accepted in IEEE Sensors Journa

Knowledge and Awareness of Diabetes Mellitus Disease among High School Students in King Abdulaziz Military City, Tabuk, Saudi Arabia

BACKGROUND: Saudi Arabia is considered to be one of the highest countries in the Middle East for the incidence of diabetes mellitus (DM). Data are lacking regarding knowledge and awareness about DM among school students in Saudi Arabia. AIM: The study aimed to assess the level of knowledge and awareness of DM among high school students within the military city, Tabuk, Saudi Arabia. METHODS: A descriptive type of cross-sectional study was conducted among 278 high school students applying a convenience sampling technique. The sample size was calculated using OpenEpi, Version 3. Self-administered questionnaires were distributed to the high school students (male and female) after official communication with the school’s dean. The level of knowledge and awareness was categorized into “adequate” and “inadequate” as per each topic/question, and also as per each response/answer. Data entry and analysis were carried out using the Statistical Package for the Social Sciences. Pearson’s Chi-square tests were performed to explore if there is any significant association between the knowledge and awareness level of the high school students and their (i) gender, (ii) age, and (iii) level of education. RESULTS: More than half of the high school students had adequate level of knowledge and awareness about DM in terms of symptoms (67.3%), complications (56.5%), monitoring method (62.6%), lifestyle modifications (63.7%), frequency of routine eye check-up (63.3%), important factors for blood sugar control (79.1%), treatment (56.5%), and management of hypoglycemia symptoms (57.6%). On the contrary, a large number of the students showed inadequate level of knowledge and awareness about the disease in terms of definition (80.6%), major causes (57.9%), effect of high blood pressure (51.8%), frequency of routine blood pressure check-up (55%), rationale of a regular urine test (58.3%), medication for DM (66.9%), and duration of medication (69.8%). However, no significant associations were found between the knowledge and awareness level of the high school students about the definition or major causes of DM and the (i) gender, (ii) age group, and (iii) level of education of the students. CONCLUSION: The level of knowledge and awareness of a considerable number of high school students regarding DM was inadequate, and some of them possessed various misconceptions about this particular chronic disease. Health authorities and school authorities in the region should offer special efforts to improve the level of knowledge and awareness of the students through regular health education campaigns

In this paper we study the geometric moments invariants. We describe an image in terms of features which are invariant to some sort of transformations i.e mentioned translation, rotation and scaling change in exposure, brightness etc. Our aim is to check the performance of components for feature vectors

The possible role of cerium oxide (CeO2) nanoparticles in prevention of neurobehavioral and neurochemical changes in 6-hydroxydopamineinduced parkinsonian disease

Cerium oxide nanoparticles (CeO2NPs) is an efficient neuroprotective agent and showed promising effects in some neurodegenerative diseases such as Alzheimer’s disease and multiple sclerosis. However, the implication of CeO2NPs in Parkinsonism remains to be investigated. The aim of this study was to assess the possible role of CeO2NPs as a neuroprotective agent against the development of behavioral and biochemical changes in rat model of Parkinson’s disease. Thirty rats were included and received left intrastriatal injection of either saline (controls, n = 10) or 6-hydroxy dopamine (6-OHDA) in untreated group (n = 10) and 10 rats were received intraperitoneal injection of low dose CeO2NPs two hours before surgery, and continued once daily for 6 weeks (preventive group). At the end of experimental period, rats were subjected to behavioral assessment and then killed for biochemical analysis of striatal dopamine levels, oxidative stress markers and caspase-3 activity. Results showed that CeO2NPs resulted in partial neuroprotection against disturbances in motor performance. It also partially decreased apoptosis and oxidative stress in preventive group, while it failed to increase striatal dopamine level as compared to untreated rats. The present study verified some neuroprotective effects of CeO2NPs in 6-OHDA-induced Parkinsonian rats through their antioxidant and anti apoptotic effects. Some of these effects persisted till the end of six weeks whereas others declined after three weeks. A larger dose may be needed to produce more valuable effects and to maintain protection for a longer period

Integrating Complementary and Alternative Medicine into Family Medicine Practice: Narrative Review

Complementary and Alternative Medicine (CAM) has witnessed a significant surge in usage across various populations and regions in recent decades. This review article delves into the prevalence and patterns of CAM usage, from cancer patients to cultural practices in Saudi Arabia and New Zealand. In Saudi Arabia, CAM practices, especially spiritual ones like prayer and reciting the Quran, are widely adopted, with herbs, honey, and dietary products also being popular. New Zealand healthcare professionals, including general practitioners and midwives, generally hold a positive view towards CAM, with acupuncture being particularly favored. However, concerns about CAM's scientific evidence, safety, and costs persist. In the U.S., while CAM is popular, many family physicians feel inadequately trained to address CAM-related patient queries. In Germany, a significant number of family physicians use CAM in their practices, emphasizing the need for increased CAM education and research. The data underscores the global trend of CAM adoption and the need for its effective integration into mainstream healthcare. Despite its popularity, the integration of CAM in medical education remains limited in many regions, including Saudi Arabia. However, there's a noticeable shift with some medical schools beginning to incorporate CAM into their curriculum. The article underscores the importance of evidence-based practice, education, training, open communication, regulation, interdisciplinary collaboration, a patient-centered approach, thorough documentation, continuous research, cultural sensitivity, and cost-effectiveness evaluation when considering the integration of CAM into mainstream healthcare. The recommendations provided aim to ensure that patients receive holistic care that is both safe and effective. The overarching theme is the need for a balanced, informed, and collaborative approach to integrating CAM into family medicine practice
