Blackboard-Based Electronic Warfare System, Jeremy Straub Oct 2015

Blackboard-Based Electronic Warfare System, Jeremy Straub

Jeremy Straub

With internet-connected, SCADA and cyber-physical systems becoming the next battlefield for crime and warfare, technologies for defending and attacking these systems are growing in prevalence. For entities with significant asset collections that are prospectively vulnerable to this type of an attack, autonomous response, retaliation and attack capabilities are necessary to respond to a growing threat from numerous sectors. This paper presents a command and control technique for cyberwarfare based on the Blackboard Architecture. It discusses the utility of this approach and proposes a distributed command system that can run across multiple nodes of various types.


Autonomous Navigation And Control Of Unmanned Aerial Systems In The National Airspace, Michael Hlas, Jeremy Straub, Eunjin Kim Apr 2015

Autonomous Navigation And Control Of Unmanned Aerial Systems In The National Airspace, Michael Hlas, Jeremy Straub, Eunjin Kim

Jeremy Straub

Pilotless aircraft known as Unmanned Aerial Vehicles (UAVs) have been used extensively for military and intelligence purposes. This includes situations where the mission area is too dangerous for a pilot to fly, the length of the mission is longer than a pilot could stay awake or aircraft are used as cruise missiles that crash into their target. With the decreasing cost and miniaturization of computers, it has become possible to build UAVs that are small and inexpensive making them accessible to businesses, law enforcement, hobbyists and the general public.

Evolution Of User Interfaces For The Visually Impaired, Umakant Mishra May 2014

Evolution Of User Interfaces For The Visually Impaired, Umakant Mishra

Umakant Mishra

Physically or mentally challenged people cannot use a computer in the same way a normal people can. For example, persons with disability in hands cannot use a standard keyboard or mouse efficiently. Persons having visual disability cannot benefit from a standard display screen. People having locomotor challenge, visual disability or hearing problem etc. cannot interact with a computer like a normal person. So it is necessary to design the computers, interfacing devices and software interfaces with special features, which can be used by the people with physical challenges.

There are many input/output devices like mouse, keyboard, pointers, and touch screens …


Designing An Mis Database For Selection And Recruitment, Umakant Mishra Sep 2013

Designing An Mis Database For Selection And Recruitment, Umakant Mishra

Umakant Mishra

Selection and recruitment is a key HR function and it is often necessary to maintain at least a small database of all the candidates who have been invited in past interviews. This information may be considered as a part of HR MIS and may be maintained by HR department along with other HR MIS such as employee information, transfers, performance appraisals, trainings etc.

This recruitment MIS database includes all the candidates after the preliminary scrutiny is over. When the candidates go through different stages of interviews, the MIS also captures all their interview results. Maintaining this information not only helps …


A Human Proximity Operations System Test Case Validation Approach, Justin Huber, Jeremy Straub Mar 2013

A Human Proximity Operations System Test Case Validation Approach, Justin Huber, Jeremy Straub

Jeremy Straub

A Human Proximity Operations System (HPOS) poses numerous risks in a real world environment. These risks range from mundane tasks such as avoiding walls and fixed obstacles to the critical need to keep people and processes safe in the context of the HPOS’s situation-specific decision making. Validating the performance of an HPOS, which must operate in a real-world environment, is an ill posed problem due to the complexity that is introduced by erratic (non-computer) actors. In order to prove the HPOS’s usefulness, test cases must be generated to simulate possible actions of these actors, so the HPOS can be shown …

Model-Based Software Engineering For An Imaging Cubesat And Its Extrapolation To Other Missions, Atif Mohammad, Jeremy Straub, Christoffer Korvald, Emanuel Grant

Jeremy Straub

Small satellites with their limited computational capabilities require that software engineering techniques promote efficient use of spacecraft resources. A model-driven approach to software engineering is an excellent solution to this resource maximization challenge as it facilitates visualization of the key solution processes and data elements.

The software engineering process utilized for the OpenOrbiter spacecraft, which is a remote sensing technology demonstrator, is presented. Key challenges presented by the Open Orbiter project included concurrent operation and tasking of five computer-on-module (COM) units and a flight computer and the associated data marshaling between local and general storage. The payload processing system (consisting …


An Effective End-User Development Approach Through Domain-Specific Mashups For Research Impact Evaluation. (Executive Summary), Muhammad Imran Jan 2013

An Effective End-User Development Approach Through Domain-Specific Mashups For Research Impact Evaluation. (Executive Summary), Muhammad Imran

Muhammad Imran

Over the last decade, there has been growing interest in the assessment of the performance of researchers, research groups, universities and even countries. The assessment of productivity is an instrument to select and promote personnel, assign research grants and measure the results of research projects. One particular assessment approach is bibliometrics i.e., the quantitative analysis of scientific publications through citation and content analysis. However, there is little consensus today on how research evaluation should be performed, and it is commonly acknowledged that the quantitative metrics available today are largely unsatisfactory. The process is very often highly subjective, and there are …


Multi-Tier Exploration Concept Demonstration Mission, Jeremy Straub May 2012

Multi-Tier Exploration Concept Demonstration Mission, Jeremy Straub

Jeremy Straub

A multi-tier, multi-craft mission architecture has been proposed but, despite its apparent promise, limited use and testing of the architecture has been conducted. This paper proposes and details a mission concept and its implementation for testing this architecture in the terrestrial environment. It is expected that this testing will allow significant refinement of the proposed architecture as well as providing data on its suitability for use in both terrestrial and extra-terrestrial applications. Logistical and technical challenges with this testing are discussed.


Privacy Protection Framework With Defined Policies For Service-Oriented Architecture, David Allison, Miriam A M Capretz, Hany Elyamany, Shuying Wang Jan 2012

Privacy Protection Framework With Defined Policies For Service-Oriented Architecture, David Allison, Miriam A M Capretz, Hany Elyamany, Shuying Wang

Miriam A M Capretz

Service-Oriented Architecture (SOA) is a computer systems design concept which aims to achieve reusability and inte-gration in a distributed environment through the use of autonomous, loosely coupled, interoperable abstractions known as services. In order to interoperate, communication between services is very important due to their autonomous nature. This communication provides services with their functional strengths, but also creates the opportunity for the loss of privacy. In this paper, a Privacy Protection Framework for Service-Oriented Architecture (PPFSOA) is described. In this framework, a Privacy Service (PS) is used in combination with privacy policies to create privacy contracts that out-line what can …

Morphogrammatics Of Reflection, Rudolf Kaehr Nov 2010

Morphogrammatics Of Reflection, Rudolf Kaehr

Rudolf Kaehr

Turning back from the studies of morphogrammatics to some open questions of reflectional programming, the recountered problematics might be put into a different light and new methods of handling formal aspects of reflection and reflectionality shall be introduced. Albeit the use of light-metaphors, morphogrammatic reflection is not sketched along the paradigm of optical metaphors. Morphograms are presenting neither propositions nor perceptions able for mirroring (representation). Exercises in defining morphogrammatic retro-grade recursion and reflection schemata are continued from the paper “Sketches to Morphogrammatic Programming”.


Enhancing Stockmarket Trading Performance With Anns, Bruce Vanstone, Gavin Finnie Sep 2010

Enhancing Stockmarket Trading Performance With Anns, Bruce Vanstone, Gavin Finnie

Gavin Finnie

Artificial Neural Networks (ANNs) have been repeatedly and consistently applied to the domain of trading financial time series, with mixed results. Many researchers have developed their own techniques for both building and testing such ANNs, and this presents a difficulty when trying to learn lessons and compare results. In a previous paper, Vanstone and Finnie have outlined an empirical methodology for creating and testing ANNs for use within stockmarket trading systems. This paper demonstrates the use of their methodology, and creates and benchmarks a financially viable ANN-based trading system. Many researchers appear to fail at the final hurdles in their …


Memristics: Memristors, Again? – Part Ii, How To Transform Wired ‘Translations’ Between Crossbars Into Interactions?, Rudolf Kaehr Apr 2010

Memristics: Memristors, Again? – Part Ii, How To Transform Wired ‘Translations’ Between Crossbars Into Interactions?, Rudolf Kaehr

Rudolf Kaehr

The idea behind this patchwork of conceptual interventions is to show the possibility of a “buffer-free” modeling of the crossbar architecture for memristive systems on the base of a purely difference-theoretical approach. It is considered that on a nano-electronic level principles of interpretation appears as mechanisms of complementarity. The most basic conceptual approach to such a complementarity is introduced as an interchangeability of operators and operands of an operation. Therefore, the architecture of crossbars gets an interpretation as complementarity between crossbar functionality and “buffering” translation functionality. That is, the same matter functions as operator and at once, as operand – …

Memristics: Memristors, Again?, Rudolf Kaehr

Rudolf Kaehr

This collection gives first and short critical reflections on the concepts of memristics, memristors and memristive systems and the history of similar movements with an own focus on a possible interplay between memory and computing functions, at once, at the same place and time, to achieve a new kind of complementarity between computation and memory on a single chip without retarding buffering conditions.


Sketch Of A Typology Of Abstract Memristic Machines, Rudolf Kaehr Jan 2010

Sketch Of A Typology Of Abstract Memristic Machines, Rudolf Kaehr

Rudolf Kaehr

A typology of memristic machines is sketched. This sketch gives an overview and orientation to the paper “Towards Abstract Memristic Machines”. It also intents to propose a concise systematization of the newly introduced terms and strategies to memristics and morphogrammatics. This sketch is introducing four types of sign-use for four types of machines of fundamentally different paradigms: 1. semiotic, 2. monomorphic, 3. polymorphic and 4. bisimilar abstract machines. Further definitions of abstract machines have to be based on those graphematic notational systems. A realization of such constructions of abstract machines, in contrast to existing abstract machines of the theory of …
