On the Chermak–Delgado Lattice of a Finite Group
No full textBy imposing conditions upon the index of a self-centralizing sub-group of a group, and upon the index of the center of the group, we are able to classify the Chermak-Delgado lattice of the group. This is our main result. We use this result to classify the Chermak-Delgado lattices of dicyclic groups and of metabelian p-groups of maximal class.https://doi.org/10.1080/00927872.2019.163232
Wage against the machine: A generalized deep-learning market test of dataset value
No full textHow can you tell whether a particular sports dataset really adds value, particularly with regard to betting effectiveness? The method introduced in this paper provides a way for any analyst in almost any sport to attempt to determine the additional value of almost any dataset. It relies on the use of deep learning, comprehensive historical box score statistics, and the existence of betting markets. When the method is applied as an illustration to a novel dataset for the NBA, it is shown to provide more information than regular box score statistics alone, and appears to generate above-breakeven wagering profits.https://doi.org/10.1016/j.ijforecast.2017.09.00
The Effects of an Interrupted Formal Education of Central American Refugees in a U.S. Urban Secondary School: A Critical Phenomenological Cross-Case Analysis
No full textThe Office of Refugee Resettlement has reported increasing numbers of Central American student refugees entering the United States. Most student refugees crossing the U.S. southwestern border come from El Salvador, Guatemala, and Honduras. Students with limited-interrupted formal education represent the neediest of English language learners due to their academic, mental, and social-emotional needs from past experiences with trauma, thereby representing a disenfranchised and vulnerable population. This critical phenomenological multiple case study explored the experiences of 2 groups of students with limited-interrupted formal education in terms of academic achievement, those defined as successful and others who struggled. 2 cases were conducted, the first to understand why some Central American student refugees had experienced academic success and the second to understand why some Central American student refugees had struggled with academic achievement. The 2 cases were compared using cross-case analysis to gain knowledge from the successful students and see if this knowledge could be applied to the struggling students. The theoretical framework included critical and Latino race, community cultural wealth, and resiliency theories. Findings showed the external support system of student participants had a significant influence on resiliency and academic achievement. Although data indicated the Newcomer Program had aided in some students’ success, evidence indicated the need for ongoing and consistent mental health services. Results showed issues regarding identifying and providing special education services to Central American student refugees with limited-interrupted formal educations
Flywheel regenerative Breaking System
No full textThe study proposed in this thesis aims to model a Flywheel Regenerative Breaking System (f-RBS). F-RBS is based on a simplified mechanical model which is meant to remove energy conversion losses while storing the power of rotational braking. f-RBS consists of a flywheel for the electricity storage system (ESS) and a V-belt Continuously Variable Transmission CVT. Mathematical models of friction analysis are derived. A model of f-RBS is designed with Solidworks™. Results showed that using the f-RBS concept could significantly influence the recycling of braking power waste and provide additional energy

Real-Time Detection of DoS Attacks in IEEE 802.11p Using Fog Computing for a Secure Intelligent Vehicular Network
No full textThe vehicular ad hoc network (VANET) is a method through which Intelligent Transportation Systems (ITS) have become important for the benefit of daily life. Real-time detection of all forms of attacks, including hybrid DoS attacks in IEEE 802.11p, has become an urgent issue for VANET. This is due to sporadic real-time exchange of safety and road emergency message delivery in VANET. Sporadic communication in VANET has the tendency to generate an enormous amount of messages. This leads to overutilization of the road side unit (RSU) or the central processing unit (CPU) for computation. Therefore, efficient storage and intelligent VANET infrastructure architecture (VIA), which includes trustworthiness, are required. Vehicular Cloud and Fog Computing (VFC) play an important role in efficient storage, computation, and communication needs for VANET. This research utilizes VFC integration with hybrid optimization algorithms (OAs), which also possess swarm intelligence, including Cuckoo/CSA Artificial Bee Colony (ABC) and Firefly/Genetic Algorithm (GA), to provide real-time detection of DoS attacks in IEEE 802.11p, using VFC for a secure intelligent vehicular network. Vehicles move ar a certain speed and the data is transmitted at 30 Mbps. Firefly Feed forward back propagation neural network (FFBPNN) is used as a classifier to distinguish between the attacked vehicles and the genuine vehicles. The proposed scheme is compared with Cuckoo/CSA ABC and Firefly GA by considering jitter, throughput, and prediction accuracy.http://dx.doi.org/10.3390/electronics807077

Solar Powered Lawn Mower
No full textEach weekend, about 54 million Americans mow their lawns, using 800 million gallons of gas per year and producing tons of air pollutants. Garden equipment engines, which have had unregulated emissions until the late 1990's, emit high levels of carbon monoxide, volatile organic compounds and nitrogen oxides, producing up to 5% of the USA’s air pollution and a good deal more in metropolitan areas. According to the U.S. Environmental Protection Agency (EPA), a new gas-powered lawn mower produces volatile organic compounds and nitrogen oxides emissions air pollution in in in one hour of operation as 11 new cars each being driven for one hour. The solar powered lawn mower is aa fully autonomous robot with capabilities to cut the grass independently. The robot uses 12v batteries to power itself and all the sensors. The motors to help move the robot and the grass cutter are controlled by and Arduino microcontroller that controls the movement based on incoming data from the ultrasonic sensors used for object detection and the humidity sensors to check for the non-grassy areas. The 12-volt battery is continuous charged by a solar panel housed on the top of the robot that also acts as a secure panel for weatherproofing the sensors underneath. The robot is compact and very cheap in comparison to any product in the market. The most common solar powered robot called the lanmow costs an upwards of $2000 and needs a technical installation. The solution presented here has a simple self-serve placement right out of the box. There is no technical installation required, no setup required and it is substantially cheaper than any current market solution while being environmentally friendly
Pattern of Internet Usage among Management and Engineering Teachers: A Comparative Study
No full textThe Internet is the worldwide publicly accessible network of interconnected computer networks that transmit data using some special protocols. It is a network of networks which consists of millions of smaller domestic, academic, business and government networks. Today, the dependency of academicians on internet has increased. They use internet for various purposes like updating knowledge, research, information sharing, seeking information, e-mail etc. This study aims to explore the various purposes for which the teachers of engineering and management institutions use Internet and also to compare the usage of Internet amongst the management and engineering teachers
