A robust, reliable and deployable framework for In-vehicle security

Cyber attacks on financial and government institutions, critical infrastructure, voting systems, businesses, modern vehicles, etc., are on the rise. Fully connected autonomous vehicles are more vulnerable than ever to hacking and data theft. This is due to the fact that the protocols used for in-vehicle communication i.e. controller area network (CAN), FlexRay, local interconnect network (LIN), etc., lack basic security features such as message authentication, which makes it vulnerable to a wide range of attacks including spoofing attacks. This research presents methods to protect the vehicle against spoofing attacks. The proposed methods exploit uniqueness in the electronic control unit electronic control unit (ECU) and the physical channel between transmitting and destination nodes for linking the received packet to the source. Impurities in the digital device, physical channel, imperfections in design, material, and length of the channel contribute to the uniqueness of artifacts. I propose novel techniques for electronic control unit (ECU) identification in this research to address security vulnerabilities of the in-vehicle communication. The reliable ECU identification has the potential to prevent spoofing attacks launched over the CAN due to the inconsideration of the message authentication. In this regard, my techniques models the ECU-specific random distortion caused by the imperfections in digital-to-analog converter digital to analog converter (DAC), and semiconductor impurities in the transmitting ECU for fingerprinting. I also model the channel-specific random distortion, impurities in the physical channel, imperfections in design, material, and length of the channel are contributing factors behind physically unclonable artifacts. The lumped element model is used to characterize channel-specific distortions. This research exploits the distortion of the device (ECU) and distortion due to the channel to identify the transmitter and hence authenticate the transmitter.Ph.D.College of Engineering & Computer ScienceUniversity of Michigan-Dearbornhttps://deepblue.lib.umich.edu/bitstream/2027.42/154568/1/Azeem Hafeez Final Disseration.pdfDescription of Azeem Hafeez Final Disseration.pdf : Dissertatio

Sonographic Evaluation of Cholelithiasis and Its Correlation with Normal/Fatty Liver

Cholelithiasis and Fatty Liver disease are usually observed to coexist. Patients who have gallstones also have Fatty Liver as both of the conditions have same associated risk factors I.e., diabetes mellitus, gender, age, obesity, metabolic syndrome, insulin resistance and high lipids level. Non-Alcoholic Fatty Liver Disease (NAFLD) is also an independent accountable risk factor for the formation of gallstones. We aimed to determine whether there is any correlation between cholelithiasis and fatty liver disease. The study was conducted in Lahore General Hospital, Lahore, Pakistan. The data was collected from March 24,2021 to May 24,2021. Informed consent was taken from all the participants. We did a cohort study comprising the data of 51 patients undergoing physical checkup. The data gathered included age, gender and whether they had normal or fatty liver. Cholelithiasis was diagnosed by confirming the presence of gallstones on abdominal ultrasonography after fasting for approximately 8hrs. it was an observational study for the assessment of correlation between cholelithiasis and fatty liver in the participants. A Total of 51 patients with cholelithiasis were included in our study. Most of the patients were 29 to 70 years of age. The average age of the patients was 42.3 ± 10.1 years. Out of 51 patients, there were 60.8% (P=31) females and 39.2%(P=20) males. Out of 51 cholelithiasis patients there were 31.4%(P=16) had Normal Liver and 68.6%(P=35) were positive with Fatty liver disease. Patients with stone size ranges from 1.90mm to 4.6mm hade Grade 1 Fatty liver as shown in table-5.4, Grade 2 Fatty liver was seen in patients with stone size ranges from 4.5mm to 5.8mm. Fatty liver Grade 3 was not observed in any included patient with cholelithiasis. Results of our study showed that both cholelithiasis and Fatty Liver disease are correlated with each other. Females are at higher risk to be affected by these with diseases. Early detection of Fatty liver in patients of cholelithiasis can help patients to prevent them further complications regarded to fatty liver and cholelithiasis and can play important role in health care of society.

Academic Achievement: Influences of University Students’ Self-Management and Perceived Self-Efficacy

Successful students are more than just those who have more effective and efficient learning techniques for acquiring and applying information. They can also motivate, evaluate, and adjust their behavior if they are not learning properly. Thus, the objective of this study was to investigate the influence of university students’ self-management during their learning experience and their self-efficacy on their academic achievement. Additionally, the study investigated the differences between the Egyptian and Saudi students’ perceptions of self-management skills and self-efficacy in their academic achievement within the two countries. A total of 889 students from two different Arab countries took part in the study (Egypt and the Kingdom of Saudi Arabia). The sample was given an online questionnaire to evaluate their self-management abilities, perceived self-efficacy, and academic achievement. A quantitative approach using SmartPLS-SEM was deployed. The findings demonstrate that self-management and self-efficacy have positive influences on students’ academic achievement in both countries. Further, self-management skills have been proven to influence self-efficacy, which in turn highly influences academic achievement. Moreover, the findings of the Multi-Group Analysis (MGA) did not report significant differences between the Egyptian and Saudi students in terms of their perception of self-management, self-efficacy, and academic achievement

Genetic Diversity of Some Tomato Cultivars and Breeding Lines Commonly Used in Pakistani Breeding Program

Genetic diversity present in gene pool is an important determination for breeding programs, and characterization is useful of building crop plant collections primarily based on the knowledge of the presence of valuable genes and traits. Developing successful varieties for increasing the future yield and quality of tomato depend mainly on the genetic diversity of parents used in the breeding program. Molecular characterization of 21 tomato genotypes used in in Pakistani breeding program was studied using random amplified polymorphic DNA (RAPD) markers. Total 102 bands were amplified among 21 genotypes using 20 RAPD primers. Overall 73.5% polymorphism was shown as 75 out of 102 loci were polymorphic. High degree of divergence between varieties was indicated by low level of monomorphic bands. The number of PCR products per primer varied from 2-8 with an average of 5.1 bands per primer. Primer GL J-20 and GL C-09 produced maximum number of bands whereas the primers GL A-09 produced the lowest. The polymorphism per RAPD primer ranged from 50% to 100% with an average of 73.5%. The accumulative analysis of amplified products generated by RAPD’s was enough to assess the genetic diversity among the genotypes. The information would be helpful for formulating future breeding and genome mapping programs. This study will also work as an indicator for tomato breeders to evolve varieties with genetic diverse back ground to achieve sustainability in tomato production in the country

The global trend of nanomaterial usage to control the important agricultural arthropod pests: A comprehensive review

Global warming and climate change have favored the resurgence of arthropod pests and their short lifecycle. The massive use of synthetic chemicals for insect pest control has indirectly favored global warming, ecotoxicity, and insecticide resistance in agricultural arthropod pests. Additionally, the increasing population of the world required more food, and a significant proportion of the agricultural produced is deteriorated by arthropod pests and other biotic and abiotic factors. Recently, nanotechnology has revolutionized the agricultural industries in the current era. Extremely small size and physio-morphic properties of nanomaterials have attracted the interest of researchers to develop nano-fertilizers, nano-pesticides, and nano-herbicides that have overwhelmed the aforementioned problems and increase crop productivity. Micronutrient based nano-pesticides like Ag, ZnO, TiO2, Cu, and SiO2 have not only enhanced the arthropod pest's biogenicity but also boost-up crop productivity. There are some apprehensions regarding nanomaterial synthesis and usage as nano-pesticides but the physio-morphic characteristics of nanostructured metals offers a cheap and excellent solution for pest control. This review article provides a comprehensive overview of the global trend in nanomaterial usage for controlling important agricultural arthropod pests. A bibliometric analysis was conducted to evaluate the research landscape and identify key trends in this field. The review encompasses various aspects, including the emergence of chemical pesticides, the fate of pesticides in arthropod pest management, and the detrimental effects of pesticides on the ecosystem.
