Enhancing Road Safety:Reckless Driver Detection via OpenCV in Simulated Environments
No full textA major traffic violation known as “reckless driving” is defined as driving with a deliberate disrespect for other people’s safety. Since there are too many unknowns in the scenario, reckless driving cannot be stopped. It is the driver’s obligation to drive safely; it is not under their control. Therefore, in order to address the issues around careless driving, we developed a method for determining whether or not a vehicle is being driven carelessly. Prior studies on the subject used the vehicle’s current speed and the presence of dents to identify the driver as careless. They neglect to take the vehicle’s trajectory into account. A car that is driving while intoxicated or that frequently changes lanes does not travel in a straight line. This trajectory can be examined to determine whether a car is being driven carelessly. With a CNN model, the vehicle’s trajectory may be examined. Without any pre-processing, analyzing the vehicle’s path would make the CNN model complex and time-consuming to train. In order to address this problem, we create a graph of the car’s trajectory and use it as input data to train a CNN model that determines whether or not the vehicle is being driven recklessly.</p
Tractable Reasoning In Knowledge Representation Systems
No full textThis dissertation addresses some problems raised by the well-known intractability of deductive reasoning in even moderately expressive knowledge representation systems. Starting from boolean constraint propagation (BCP), a previously known linear-time incomplete reasoner for clausal propositional theories, we develop fact propagation (FP) to deal with non-clausal theories, after motivating the need for such an extension. FP is specified using a confluent rewriting systems, for which we present an algorithm that has quadratic-time complexity in general, but is still linear-time for clausal theories. FP is the only known tractable extension of BCP to non-clausal theories; we prove that it performs strictly more inferences than CNF-BCP, a previously-proposed extension of BCP to non-clausal theories.
We generalize a refutation reasoner based on FP to a family of sound and tractable reasoners that are increasingly complete" for propositional theories. These can be used for anytime reasoning, i.e., they provide partial answers even if they are stopped prematurely, and the completeness" of the answer improves with the time used in computing it. A fixpoint construction based on FP gives an alternate characterization of the reasoners in this family, and is used to define a transformation of arbitrary theories into logically-equivalent vivid" theories | ones for which our FP algorithm ii is complete.
Our final contribution is to the description of tractable classes of reasoning problems. Based on FP, we develop a new property, called bounded intricacy, which is shared by a variety of tractable classes that were previously presented, for example, in the areas of propositional satisfiability, constraint satisfaction, and OR-databases. Although proving bounded intricacy for these classes requires domain-specific techniques (which are based on the original tractability proofs), bounded intricacy is one more tool available for showing that a family of problems arising in some application is tractable. As we demonstrate in the case of constraint satisfaction and disjunctive logic programs, bounded intricacy can also be used to uncover new tractable classes.Technical report DCS-TR-32
Surgically induced astigmatism after phacoemulsification by temporal clear corneal and superior clear corneal approach: a comparison
No full textArchana Sunil Nikose, Dhrubojyoti Saha, Pradnya Mukesh Laddha, Mayuri Patil Department of Ophthalmology, N.K.P. Salve Institute and LMH, Nagpur, Maharashtra, India Introduction: Cataract surgery has undergone various advances since it was evolved from ancient couching to the modern phacoemulsification cataract surgery. Surgically induced astigmatism (SIA) remains one of the most common complications. The introduction of sutureless clear corneal incision has gained increasing popularity worldwide because it offers several advantages over the traditional sutured limbal incision and scleral tunnel. A clear corneal incision has the benefit of being bloodless and having an easy approach, but SIA is still a concern.Purpose: In this study, we evaluated the SIA in clear corneal incisions with temporal approach and superior approach phacoemulsification. Comparisons between the two incisions were done using keratometric readings of preoperative and postoperative refractive status.Methodology: It was a hospital-based prospective interventional comparative randomized control trial of 261 patients conducted in a rural-based tertiary care center from September 2012 to August 2014. The visual acuity and detailed anterior segment and posterior segment examinations were done and the cataract was graded according to Lens Opacification Classification System II. Patients were divided for phacoemulsification into two groups, group A and group B, who underwent temporal and superior clear corneal approach, respectively. The patients were followed up on day 1, 7, 30, and 90 postoperatively. The parameters recorded were uncorrected visual acuity, best-corrected visual acuity, slit lamp examination, and keratometry. The mean difference of SIA between 30th and 90th day was statistically evaluated using paired t-test, and all the analyses were performed using SPSS 18.0 (SPSS Inc.) software.Results: The mean postoperative SIA in group A was 0.998 D on the 30th day, which reduced to 0.768 D after 90 days, and in group B the SIA after 30 days was 1.651 D, whereas it reduced to 1.293 D after 90 days.Conclusion: Temporal clear corneal incision is evidently better than superior clear corneal incision as far as SIA is concerned. Keywords: phacoemulsification, temporal, clear corneal, SI
Assess the Effectiveness of Self-Instructional Module on Knowledge regarding Adverse Effects of Antipsychotic Drugs among Care Takers of Mentally Ill Patients
No full textThis study was conducted to assess the knowledge level of all the care takers of mentally ill patients. The self instructional module significantly brought out their improvement in the knowledge regarding adverse effects of antipsychotic drugs An adverse effect may be caused by administration of an antipsychotic medication or by exposure to a chemical and be indicated by an untoward result such as extrapyramidal symptom, etc. The data was collected with structured interview schedule and then analysis of data done and the findings showed that there was significant difference between pre-test and post test knowledge of care takers
