Analysis Of A ‘Turn-Key’ No Hardware Space Mission Using The Orbital Services Model, Jeremy Straub

Jeremy Straub

Many applications that would benefit from access to space cannot afford the cost of spacecraft development, launch and operations. Other operations require only a fraction of a spacecraft or complete use of a spacecraft for a limited period of time. This paper considers the value of a ‘turn-key’ style space mission. It considers what types of missions could be reasonably conducted using this approach. The economics of being a service provider are considered. Then, a prospective mission concept for one OSM ‘turn-key’ mission is presented. The value proposition of this mission is assessed and the hardware and other capabilities required …

Nanosatellite Scheduling Using A Dictionary Module And A ‘Useful Trick’ With Coded Unsigned Integers, Monilito Castro, Jeremy Straub

Jeremy Straub

Schedulers for small spacecraft must satisfy the dual requirement of generating very efficient schedules while concurrently minimizing the resources required to create the schedule. This paper proposes a technique for searching for tasks that can be utilized to fill particular schedule locations. This approach is based on a modular system for storing important variables. This modular system has three important variables: t0, x0 and y0. The variable y is latitude and x is longitude. Time variable t is an integer and each unit represents a time quantum. They are related to each other by three functions Ft, Fx, and Fy. …

Swarm Intelligence, A Blackboard Architecture And Local Decision Making For Spacecraft Command, Jeremy Straub

Jeremy Straub

Control of a multi-spacecraft constellation is a topic of significant inquiry, at present. This paper presents and evaluates a command architecture for a multi-spacecraft mission. It combines swarm techniques with a decentralized / local decision making architecture (which uses a set of shared blackboards for coordination) and demonstrates the efficacy of this approach. Under this approach, the Blackboard software architecture is used to facilitate data sharing between craft as part of a resilient hierarchy and the swarm techniques are used to coordinate activity. The paper begins with an overview of prior work on the precursor command technologies and then presents …

Small Satellite Communications Security And Student Learning In The Development Of Ground Station Software, Scott Kerlin, Jeremy Straub, Jacob Huhn, Alexander Lewis

Jeremy Straub

Communications security is gaining importance as small spacecraft include actuator capabilities (i.e., propulsion), payloads which could be misappropriated (i.e., high resolution cameras), and research missions with high value/cost. However, security is limited by capability, interoperability and regulation. Additionally, as the small satellite community becomes more mainstream and diverse, the lack of cheap, limited-to-no configuration, pluggable security modules for small satellites also presents a limit for user adoption of security.

This paper discusses a prospective approach for incorporating robust security into a student-developed ground station created at the University of North Dakota as part of a Computer Science Department senior design …

Novel Informatic Platform For The Standard Unification Of Donors, Offspring And Patients Records: Institutional Registry Requirements In The Reproductive Biomedicine Regulations Compliance., Salvo Reina, Mauro Costa, Mauro Giacomini

Salvo Reina

The Donor ART (DART), recently promulgated by italian institution, has posed several incumbent questions to the Artificial Reproductive Techniques (ART) world. Besides the critical social and ethical aspects, a crucial issue is the engagement of a centralised “Donors-offspring Registry” which introduces new stringent criteria up on the treatments of the sensitive data of donors, newborns and patients. Such registry will have to comply with applicable italian laws (Legge 40/04, Dlg.191/07 and Dlg.16/10, the so called “Patto per la Salute 2014-2016) and the european Tissue Directive (2006/17/CE, Ed. 2004).

Contextual Anomaly Detection Framework For Big Sensor Data, Michael Hayes, Miriam A M Capretz

Miriam A M Capretz

The ability to detect and process anomalies for Big Data in real-time is a difficult task. The volume and velocity of the data within many systems makes it difficult for typical algorithms to scale and retain their real-time characteristics. The pervasiveness of data combined with the problem that many existing algorithms only consider the content of the data source; e.g. a sensor reading itself without concern for its context, leaves room for potential improvement. The proposed work defines a contextual anomaly detection framework. It is composed of two distinct steps: content detection and context detection. The content detector is used …

Enhanced Routing Protocol For Multihop Cognitive Radio Wireless Networks, Rana Asif Rehman, Chan-Min Park, Byung-Seo Kim

Rana Asif Rehman

Since multihop cognitive radio wireless networks are resource-constraint networks, there is a need of routing scheme that takes into account the parameters like channel information, node’s remaining energies, end-to-end latency etc., while performing routing process. In this paper, we have proposed a reliable and efficient routing scheme for multihop cognitive radio wireless networks. The proposed protocol is on-demand and reactive protocol that considers both delay and energy along the route. By using simulations, it shows that proposed scheme performs better as compared to other ones.

Introduction To Anti-Collision Algorithms And Estimation Methods In Rfid Systems, Masoud Shakiba

Masoud Shakiba

The main objective of Radio Frequency Identification (RFID) systems is to provide fast identification for tagged objects. The noteworthy advantage of RFID technology, is its capability to identify objects simultaneously. However, when radio frequency signals are emitted simultaneously, there is a probability of collision occurrence, and thereby resulting in a waste of resources. Collision is a time-consuming event that reduces the performance of RFID systems. Consequently, several anti-collision algorithms have been proposed in the literature, attempt to decrease the collision occurrence probability. In almost all the existing anti-collision algorithms, a prior knowledge of the number of tags has a significant …

L2er: Low-Latency And Energy-Based Routing Protocol For Cognitive Radio Ad Hoc Networks, Rana Asif Rehman, Byung-Seo Kim

Rana Asif Rehman

Cognitive radio ad hoc networks (CRAHNs) are active, self-organized, and dynamic networks, in which cognitive users can communicate with each other in an ad hoc fashion. Various delay and energy-based routing protocols have been proposed for CRAHNs. However, these protocols do not consider the delay and node energy in the routing process, which can significantly affect performance. Delay and node energy are important factors in ad hoc networks in which devices have limited power. In this paper, we propose a new routing protocol, named low-latency and energy-based routing (L2ER) protocol; it considers both delay and energy for the routing decisions …

Introduction To Rfid Technology And Collision Problem, Masoud Shakiba

Masoud Shakiba

Radio Frequency Identification (RFID) system is a new communication technology to identify the objects using electromagnetic waves. The main superiority of RFID systems in comparison with other identification systems, such as barcodes, is its ability in simultaneous identification process, but when more than one tag wants to communicate with the reader, collision problem occurs and wastes time and increases energy consumption. This reduces efficiency of the identification process in RFID systems. Collision problem happens when the reader has to identify more than one tag at the same time. Consequently, it is essential to develop an efficient anti-collision algorithm to save …

Adrian Bonilla-Petriciolet

This study introduces a new algorithm for the ant colony optimization (ACO) method, which has been proposed to solve global optimization problems with continuous decision variables. This algorithm, namely ACO-FRS, involves a strategy for the selection of feasible regions during optimization search and it performs the exploration of the search space using a similar approach to that used by the ants during the search of food. Four variants of this algorithm have been tested in several benchmark problems and the results of this study have been compared with those reported in literature for other ACO-type methods for continuous spaces.
