Development Of Diagnostic Tools And Analysis Of The Density Functional Theory Zoo, Pierpaolo Morgante
Development Of Diagnostic Tools And Analysis Of The Density Functional Theory Zoo, Pierpaolo Morgante
Theses and Dissertations
The main goal of this dissertation is to give an overview of existing and new databases for density functional theory (DFT). It describes the procedures used to introduce A Collection of Chemistry DataBases (ACCDB) and its reduction to a smaller and statistically significant database called A Small(er) Collection of DataBase (ASCDB). Also, it presents an application of such databases in chemical education through the introduction of a notebook of twelve exercises that can easily complement a computational chemistry class. In addition, a new database of molecules having carbon-carbon long bonds (CLB18) is presented. Last, the databases are used in the …
Iot Security For Iotmon Attacks Based On Devices’ App Description, Raghad Jameel A. Alhazmi
Iot Security For Iotmon Attacks Based On Devices’ App Description, Raghad Jameel A. Alhazmi
Theses and Dissertations
There are concerns associated with ”inter-app” interactions, which occur when many independently developed home automation apps interact and affect one another, causing possibly dangerous unexpected app action. We extended a security tool named IoTMon, an IoT device management system capable of identifying all potential cross-app communication paths and analyzing their danger status. As part of our work, we keep an eye on the app description and safeguard IoTMon from being altered in any way that could obscure the real interaction related to another app action. We validate the IoTMon system’s integrity by applying the hash algorithm SHA512 with digital signature …
Toward A Labeled Dataset Of Iot Malware Features, Stian Hagboe Olsen
Toward A Labeled Dataset Of Iot Malware Features, Stian Hagboe Olsen
Theses and Dissertations
IoT malware has accompanied the rapid growth of embedded devices over the last decade. The last few years have seen increased work on static and dynamic detection and classification techniques for IoT malware. However, this work requires a very diverse and fine-grained set of malware-specific characteristics. This paper takes a step toward constructing a large-scale, diverse, and open-source IoT malware dataset. To demonstrate the depth of the dataset, we propose an approach for recovering symbol tables and detecting the intent of stripped IoT malware binaries using function signature libraries and 14 defining Linux malware features with corresponding regular expressions. We …
Dirichlet Type Boundary Value Problems For Linear And Quasi{Linear Hyperbolic Equations Of Higher Order, Reemah Alhuzally
Dirichlet Type Boundary Value Problems For Linear And Quasi{Linear Hyperbolic Equations Of Higher Order, Reemah Alhuzally
Theses and Dissertations
Dirichlet type problems for quasi-linear hyperbolic equations are considered. For two-dimensional boundary value problems there are established:
(i) Unimprovable sufficient conditions of unique solvability and well-posedness of linear problems in piecewise smooth domains;
(ii) Unimprovable Sufficient conditions of unique solvability of linear problems in smooth convex domains.
(iii) Optimal Sufficient conditions of solvability, unique solvability and strong well-posedness of quasi-linear problems in piecewise smooth domains;
(iv) Optimal sufficient conditions of solvability and unique solvability of quasi- linear problems in smooth convex domains.
For three-dimensional linear boundary value problems there are established:
(i) Unimprovable sufficient conditions of unique solvability and well-posedness …
The Development Of A New All-In-One Allsky Camera And Radiometer System, Ashley Suzanne Hughes
The Development Of A New All-In-One Allsky Camera And Radiometer System, Ashley Suzanne Hughes
Theses and Dissertations
We developed a new all-in-one camera and radiometer system for meteor surveillance. It proved successful during its first bolide event on 13 April 2021, as reported in the journal Meteoritics and Planetary Science, volume 57, number 3, pages 575-587. The event capture produced both video and radiometric data, and with the video data we were able to calculate a trajectory and orbit, and determine the fragmentation characteristics of the meteor as it traveled through the atmosphere.
A Method To Evaluate The Impact Of Assistive Displays On The Comfort And Safety Of Driving In Low Visibility Conditions, Hussain Talal Alatiyyah
A Method To Evaluate The Impact Of Assistive Displays On The Comfort And Safety Of Driving In Low Visibility Conditions, Hussain Talal Alatiyyah
Theses and Dissertations
Natural phenomena may affect car drivers in terms of having a clear view. It may hinder or distract the driver’s eyesight from essential objects, such as traffic signs, people, or other obstacles in the street. A poor view for a driver could cause accidents that lead to significant harm. Fog is one of these natural phenomena that could impact a driver’s concentration. This study aims to test a methodology for evaluating the use of an assistive computer display, especially in fog situations. An experiment is performed with participants who perform simulated driving under controlled fog conditions with or without an …
Dynamic Task Allocation And Understanding Of Situation Awareness Under Different Levels Of Autonomy In Closed-Hatch Military Vehicles Using Virtual Reality, Jessie E. Cossitt
Dynamic Task Allocation And Understanding Of Situation Awareness Under Different Levels Of Autonomy In Closed-Hatch Military Vehicles Using Virtual Reality, Jessie E. Cossitt
Link Foundation Modeling, Simulation and Training Fellowship Reports
The current state of the art in autonomous vehicles is partial autonomy, and to optimize the use of these vehicles, it is essential to understand the interactions between the vehicles and their operators. Partially autonomous vehicles require operators to perform parts of the driving task and to be alert and ready to take over full control of the vehicle at any point. Due to the requirements on the human operator, it is necessary to know how the operators' abilities are impacted by the amount of autonomy present in the system. There are known effects of autonomous systems on performance, cognitive …
