Securecoin: A Robust Secure And Effi#14;Cient Protocol For Anonymous Bitcoin Ecosystem, Maged H. Ibrahim 2017 Helwan University

Securecoin: A Robust Secure And Effi#14;Cient Protocol For Anonymous Bitcoin Ecosystem, Maged H. Ibrahim

Maged Ibrahim

Bitcoin is the #12;rst decentralized peer-to-peer electronic
virtual asset and payment cryptocurrency, through which,
users can transact digital currency directly, without the
need for an intermediary (or authority), using a hashed
version of cryptographic public keys, as pseudonyms
called addresses. The Bitcoin ecosystem was supposed
to be anonymous and untraceable. However, transactions
from input to output addresses of the Bitcoin users are
observed to be linkable, therefore, missing unlinkability
as an important requirement of anonymity. Several pro-
tocols appeared to enhance Bitcoin users' anonymity and
to ensure unlinkability of input-output addresses, to make
input and output addresses of transactions ...

Are We Making A Better World With Information And Communication Technology For Development (Ict4d) Research? Findings From The Field And Theory Building, Sajda Qureshi

Sajda Qureshi

As Information and Communication Technologies (ICTs) continue to penetrate people’s lives the world over, there is a sense that understanding the role of ICTs in the context of development needs to be conceptualized theoretically while making empirical contributions that add to what we know (Avgerou, 2008; Davison, 2012; Sein and Harindranath, 2004; Sahay and Walsham, 1995). Other scholars have pointed to the importance of this research for the field of Information Systems (ISs) in offering broader contributions. Avgerou (2008) suggests that in the era of globalization such research offers contributions in ISs beyond “organizational organizational and national boundaries and ...

Artificial Agents, Cloud Computing, And Quantum Computing: Applying Floridi’S Method Of Levels Of Abstraction, Marty J. Wolf, Frances Grodzinsky, Keith W. Miller

Frances Grodzinsky

In his paper “On the Intrinsic Value of Information Objects and the Infosphere,” Luciano Floridi asserts that the goal of Information Ethics (IE) “is to fill an ‘ethical vacuum’ brought to light by the ICT revolution, to paraphrase Moor” (1985). He claims “IE will prove its value only if its applications bear fruit. This is the work that needs to be done in the near future” (Floridi 2002). Our chapter proposes to do part of that work. Initially we focus on Floridi’s Method of Levels of Abstraction (LoA). We begin by examining his methodology as it was first developed ...


A Causal Model To Predict Organizational Knowledge Sharing Via Information And Communication Technologies, Simon Cleveland 2016 Nova Southeastern University

A Causal Model To Predict Organizational Knowledge Sharing Via Information And Communication Technologies, Simon Cleveland

Simon Cleveland

Knowledge management literature identifies numerous barriers that inhibit employees' knowledge seeking and knowledge contributing practices via information and communication technologies (ICTs). Presently, there is a significant gap in the literature that explains what factors promote common knowledge sharing barriers. To bridge this gap, this study examined two research questions: 1) What are the potential factors that contribute to the commonly accepted barriers to knowledge sharing?, and 2) How do these factors impact employees' use of ICTs for knowledge seeking and knowledge contributing? Literature review of 103 knowledge management articles identified three major barriers to knowledge sharing practices (lack of time ...


Toward Autonomous Multi-Rotor Indoor Aerial Vehicles, Connor Brooks 2016 Western Kentucky University

Toward Autonomous Multi-Rotor Indoor Aerial Vehicles, Connor Brooks

Honors College Capstone Experience/Thesis Projects

In this project, we worked to create an indoor autonomous micro aerial vehicle (MAV) using a multi-layer architecture with modular hardware and software components. We required that all computing was done onboard the vehicle during time of flight so that no remote connection of any kind was necessary for successful control of the vehicle, even when flying autonomously. We utilized environmental sensors including ultrasonic sensors, light detection and ranging modules, and inertial measurement units to acquire necessary environment information for autonomous flight. We used a three-layered system that combined a modular control architecture with distributed on-board computing to allow for ...

High Altitude Cosmic Ray Detection, Jordan D. Van Nest 2016 Trevecca Nazarene University

High Altitude Cosmic Ray Detection, Jordan D. Van Nest

2016 Academic High Altitude Conference

Cosmic rays are high energy atomic nuclei travelling near the speed of light that collide with atoms and molecules in Earth’s upper atmosphere (primarily with nitrogen and oxygen), breaking down into a shower of particles of various energies in the stratosphere. As they travel earthward, these particles continue to break down and lose energy which results in relatively little ionizing radiation reaching the surface. Due to the scattering of cosmic rays, the angle at which the rays enter the atmosphere can affect the number and energies of ionizing particles detected at various altitudes. When using a standard Geiger counter ...


What's All The Fuss About Coding?, Tim Bell 2016 University of Canterbury

What's All The Fuss About Coding?, Tim Bell

2009 - 2016 ACER Research Conferences

The idea of teaching ‘coding’ to school students has become popular, and the term appears in the names of many initiatives, such as Hour of Code and Code Club. But what do we really mean by ‘coding’, and why would you want every child to learn it? Won’t it be outdated soon? This paper looks at these issues, and why topics such as computer science are being taught to all students. This includes an assessment of misunderstandings around the idea of compulsory programming for every student, and the challenges that accompany the introduction of such topics into schools.

Integrating Strategic And Tactical Rolling Stock Models With Cyclical Demand, Michael F. Gorman 2016 University of Dayton

Integrating Strategic And Tactical Rolling Stock Models With Cyclical Demand, Michael F. Gorman

Michael F. Gorman

In the transportation industry, companies position rolling stock where it is likely to be needed in the face of a pronounced weekly cyclical demand pattern in orders.

Strategic policies based on assumptions of repetition of cyclical weekly patterns set rolling stock targets; during tactical execution, a myriad dynamic influences cause deviations from strategically set targets. We find that optimal strategic plans do not agree with results of tactical modeling; strategic results are in fact suboptimal in many tactical situations. We discuss managerial implications of this finding and how the two modeling paradigms can be reconciled.


Pricing And Product Mix Optimization In Freight Transportation, Michael F. Gorman 2016 University of Dayton

Pricing And Product Mix Optimization In Freight Transportation, Michael F. Gorman

Michael F. Gorman

We propose improved pricing and market mix can improve the profitability of the freight transportation provider through the reduction of equipment repositioning costs. We hypothesize that because of complexities surrounding pricing and equipment repositioning costing, existing pricing strategies in freight transportation fail to fully consider these costs. We test this hypothesis in an applied setting in which Monte Carlo simulation captures the stochasticity of market conditions inherent in the problem. We use a heuristic to improve the nondifferentiable, discontinuous objective function.

Our results from test cases show with high confidence that current prices are not optimal, as indicated by a ...

Irish Cios’ Influence On Technology Innovation And It-Business Alignment, Harvey Enns, Joseph J. Mcdonagh

Harvey Enns

Technology is the driving force behind many of today’s new products, services, and cost-cutting measures. However, there are gaps in our understanding about how technological innovation is fostered and nurtured in organizations. Part of the answer is to examine how Chief Information Officers (CIOs) exercise influence regarding technological innovation in organizations. This is particularly important since the CIO is the head of technology in organizations, an important source of technological innovation. This article draws on an established executive influence framework to demonstrate how Irish CIOs are able to solidify Information Technology’s (IT’s) contribution to technological innovation via ...
