The Design of an Autonomous Vehicle Research Platform

Walling, Denver Hill 14 September 2017 (has links)
Self-driving cars used to be a concept of a future society. However, through years of research, testing, and dedication they are becoming a modern day reality. To further expand research and testing capabilities in the field of autonomous vehicles, an Autonomous Vehicle Research Platform (AVRP) can be developed. The purpose of an AVRP is to provide researchers with an autonomous ground vehicle testing platform they can outfit with sensors and equipment to meet their specific research needs. The platform will give researchers the capabilities to test algorithms, new sensors, navigation, new technologies, etc. that they believe would help advance autonomous vehicles. When their testing is done, their equipment can be removed so the next researcher can utilize the platform. The scope of this thesis is to develop the operational specifications for an AVRP that can operate at level 4 autonomy. These specifications include navigation and sensing hardware, such as LIDAR, radar, ultrasonic, cameras, and important specifications that pertain to using each, as well as a review of optimal mounting locations. It will also present benchmarks for computing, design specs for power and communication buses, and modifications for universal mounting racks. / Master of Science

Towards a privacy-preserving platform for apps

Lee, Sangmin 09 February 2015 (has links)
On mobile platforms such as iOS and Android, Web browsers such as Google Chrome, and even smart televisions such as Google TV or Roku, hundreds of thousands of software apps provide services to users. Their functionality often requires access to potentially sensitive user data (e.g., contact lists, passwords, photos), sensor inputs (e.g., camera, microphone, GPS), and/or information about user behavior. Most apps use this data responsibly, but there has also been evidence of privacy violations. As a result, individuals must carefully consider what apps to install and corporations often restrict what apps employees can install on their devices, to prevent an untrusted app—or a cloud provider that an app communicates with—from leaking personal data and proprietary information. There is an inherent trade-off between users’ privacy and apps’ functionality. An app with no access to user data cannot leak anything sensitive, but many apps cannot function without such data. A password management app needs access to passwords, an audio transcription app needs access to the recordings of users’ speech, and a navigation app needs users’ location. In this dissertation, we present two app platform designs, πBox and CleanRoom, that strike a useful balance between users’ privacy and apps’ functional needs, thus shifting much of the responsibility for protecting privacy from the app and its users to the platform itself. πBox is a new app platform that prevents apps from misusing information about their users. To achieve this, πBox deploys (1) a sandbox that spans the user’s device and the cloud, (2) specialized storage and communication channels that enable common app functionality, and (3) an adaptation of recent theoretical algorithms for differential privacy under continual observation. We describe a prototype implementation of πBox and show how it enables a wide range of useful apps with minimal performance overhead and without sacrificing user privacy. In particular, πBox develops the aforementioned three techniques under the assumption of limited sharing of personal data. CleanRoom extends πBox and is designed to protect confidentiality in a "Bring Your Own Apps" (BYOA) world in which employees use their own untrusted third-party apps to create, edit, and share corporate data. CleanRoom’s core guarantee is privacy-preserving collaboration: CleanRoom enables employees to work together on shared documents while ensuring that the documents’ owners—not the app accessing the document—control who can access and collaborate on the document. To achieve this guarantee, CleanRoom partitions an app into three parts, each of which implements a different function of the app (data navigation, data manipulation, and app settings), and controls communication between these parts. We show that CleanRoom accommodates a broad range of apps, preserves the confidentiality of the data that these apps access, and incurs insignificant overhead (e.g., 0.11 ms of overhead per client-server request). Both πBox and CleanRoom use differential privacy for apps to provide feedback to their publisher. This dissertation explores how to adapt differential privacy to be useful for app platforms. In particular, we investigate an adaptation of re- cent theoretical algorithms for differential privacy under continual observation and several techniques to leverage it for useful features in an app environment including advertising, app performance feedback, and error reporting. / text

The impact of platform based product variety on product family performance : examining the mediational roles of new product development proficiencies and structural features

Kim, Jung Yoon January 2003 (has links)
In order to satisfy heterogeneous and unstable consumer demands, firms increasingly leverage product development efficiencies by adopting a platform approach, based on cross-sharing of resources, for developing and introducing product variants, constituting a product family. Although the benefits and costs of utilising platform-based product development to increase product variety have been addressed by previous research, there has been little empirical work focusing on the managerial factors that enable firms to successfully develop new products that extend the product family. The current study addressesth e gap in our understandingo f the relationships between a firm's product variety strategy, new product development (NPD) proficiencies and structural features, and product family performance. The current study's findings are based on data collected from a sample of one hundred South-Korean manufacturers in a wide range of assembling industries. When firms expand platform-based product variety, superior predevelopment planning proficiencies in platform projects are essential for securing all dimensions of product family performance (i. e., operational/technical performance, profitability, and market share/sales)P. roduct family successi s also conditional upon highly proficient execution of marketing activities (business and market opportunity analysis and planning, and commercialisation) in both platform and derivative projects. The findings of this research stress the primacy of predevelopment planning and marketing capabilities. In addition, the findings of this research stress specific structural mechanisms (e. g., spatial proximity, formalisation, and organisational modularity), as drivers of product family performance. This study contributes to the understanding of inter-relationship between platform-based product variety, NPD proficiencies and structural features, and product family performance. This study can act as a guide to further studies of platform-based product development, as well as being useful to practitioners who develop product families.

Cliff and shore platform development in the Isle of Man

Phillips, Brian A. M. January 1969 (has links)
Cliffs and shore platforms are, typical landforms of the rock coast of Britain, but due to their historical significance, discussion of these features is directed mainly towards elucidation of their place in the chronology of Pleistocene glaciation. Though the Isle of Man would seem by its position to offer advantages for a further chronological study, it is proposed that existing studies of a correlative nature suffer limitations due to certain assumptions concerning the form and process of formation of these features. This dissertation contributes a thorough examination of form, with the object of inferring process and sequence from this approach. Particular attention is paid to the present tidal and offshore zones, the relation of present tides and marine activity to the existing form being expressed by survey measurements with respect to a datum.

The effect of sea induced motion on offshore process equipment

White, Graeme January 1990 (has links)
The performance of offshore process equipment on floating production platforms may be reduced through imposed sea motion. Fluid sloshing inside primary separators and non-segregated storage tanks may lead to oil/water mixing. The aim of previous work into sloshing has been to prevent damage to LNG tankers and increase the stability of space rockets. Work into oil/water sloshing appears limited. A computer controlled motion simulator was developed to conduct experiments with two rectangular vessels filled with air, refined oil and water. Two single sinusoidal forcing motions were applied, pitch and surge at various amplitudes and periods. Additional experiments were conducted with combined forcing motions pitch/roll and pitch/surge. Air/water interface profiles were measured and analysed using a computer based data logging and processing system. Air/oil and oil/water profiles were recorded using high speed video equipment. Also studied were the effect of baffles in reducing interface amplitude and the effect of forcing on oil/water transfer. A linear theory was derived to predict natural frequencies of three fluid systems and a numerical model was developed to predict near resonant behaviour. Air/water experiments and numerical model showed a coupling of natural and forcing frequencies in the free surface frequency spectrum. Favourable comparisons were also seen between the numerical model and oil/water experiments. Additional experiments indicated that oil/water mixing is promoted by resonant forcing in an unbaffled vessel. The presence of baffles reduces interfacial breakup and hence reduces oil content of water.
