Managing Complex Technology Innovation: The Need to Move Beyond Stages and Gates
Zoe Szajnfarber, Annalisa L. Weigel.
R&D management practices in engineering organizations typically conceptualize complex product innovation as a Stage-Gate process whereby novel concepts are matured through successions of development stages and progressively winnowed down at each sequential gate. This view assumes that maturity is a...
Effects and Benefits of Space Exploration: Past, Present and Future
Norma B. Crosby.
It has been more than half a century since humans first ventured into space. While competing in being the first to land on the Moon, they learned to utilize space for human needs on Earth (e.g., telecommunications, navigation systems). Many space technologies were later applied to basic needs on Earth....
Investigating Public Acceptance on Public Oriented Human Space Commercialization
Alex Monchak, Ki-Young Jeong, James Helm.
Based on people’s enthusiasm and economical reasons, space commercialization will get more momentum in the future, and eventually reach a full commercialization status, a public-oriented human space commercialization (POHSC) where the public freely participate and purchase space products and services....
Mechanisms of Innovation in the Space and Defense Sector: A Review
Zoe Szajnfarber, Annalisa L. Weigel.
Despite a rich legacy of space sector technological achievements, agencies are increasingly being criticized for their inability to deliver on their innovative promises. Although the phenomenon of innovation has received substantial attention across multiple disciplines, it has largely focused on...
The BABEL Tower: A Super-Tall Structure with a Sub-Orbital Elevator
The idea of reaching the heavens has captivated humans throughout the ages. Rockets have proved extremely inefficient in overcoming this challenge and constructing a “Centrifugally Extended Carbon Nano-Tube Tether Space Elevator” (CECNTTSE) presents unsolved technological challenges. The authors...
BOREAS Space and the Prospects for Private Spaceflight in Bulgaria
Zdravko Dimitrov, Boncho Nikov, Georgi Petrov, Boris Tashev.
BOREAS Space is a private aerospace organisation based in Sofia, Bulgaria. It was formed around the Sofia-based core of participants in the Bulgarian Orbital REsearch And Satellites (BOREAS) initiative, which included students in Bulgaria, Canada and the United Arab Emirates. Since then, the team has...

Suha Afaneh, Issam Al Hadid.
This paper introduces the different aviation and airport information technology systems. Also, this paper provides Airport Enterprise Service Bus with Three Levels Self-Healing Architecture based on the Service Oriented Architecture (SOA) that improves the information accessibility and sharing across...
Pehuensat-1: Development and Flight Test of a Nano Satellite
Juan Jorge Quiroga, Jorge Lassig, Darío Mendieta.
Nowadays, it is possible to achieve low cost and short production times space missions using satellites with a mass below 10 kg. These small satellites are described as nanosatellites. Current microelectronic technology makes it possible to develop nanosatellites for scientific experiments and...
Applications of Virtual Reality Technologies in Architecture and in Engineering
Virtual reality (VR) is a technology which permits to create virtual objects and 3D virtual worlds which are hosted on the computer’s memories. It is indispensable in critical simulation, for instance in military training, in surgical operation simulation, in creation of environments which could set...
Designing for Human Factors in the Technology-Intensive Domain of Fighter Aircraft
Jens Alfredson, Rikard Andersson.
This paper aims at describing how to design for human factors in the technology-intensive domain of fighter aircraft. Similar to space industry, the fighter aircraft industry has to manage technology-intensive development where the end user often has implicit or explicit human factors requirements or...
