“NoSQL” And Service Science

Discussions of “NoSQL” naturally tend to contrast a new approach with a tired old approach. An example is the discussion in Linux Journal (Batholomew, 2010) which focused on differentiating between these new “nonrelational” products and “traditional” (relational) systems. While enthusiasm for the new (and the unjustified raised expectations) has often been the hallmark of information systems and computing, in this instance the enthusiasm may be providing a poor and misleading explanation. A more careful explanation is needed, particularly as these approaches and products may be needed to provide the realization of many promising ideas such as those associated as with Web Services

Securing Confidence With Data Escrow

In the past several years, the general public has had concerns about hacking and identity theft. Headlines in news media include computer system breaches at popular and respected companies like Target and universities like The University of California at Berkeley. This paper explores options available for providing the general public with the benefits of the information age while mitigating against the security risks. We begin with a discussion of it is reasonable for the general public to expect organizations engaged primarily in commerce to provide for their cybersecurity. We then look at how electronic transactions are currently secured. We conclude with a consideration of the “protocols” or “institutions” that might provide for security for consumers

Big Data Options For Small And Medium Enterprises

The terms Cloud Computing and Big Data are often used in the media. Small and medium sized businesses are realizing that the amount of data they handle could be very large and important in their decision making and planning. This paper explores the options for handling large amounts of, or “Big” data in small and medium-sized enterprises. This research considers not just the volume of data, but the variety of types of data, the velocity in which data is created and transmitted, as well as the importance of data veracity. Cloud computing is a potential solution

Solid Rocket Booster (SRB) - Evolution and Lessons Learned During the Shuttle Program

The Solid Rocket Booster (SRB) element integrates all the subsystems needed for ascent flight, entry, and recovery of the combined Booster and Motor system. These include the structures, avionics, thrust vector control, pyrotechnic, range safety, deceleration, thermal protection, and retrieval systems. This represents the only human-rated, recoverable and refurbishable solid rocket ever developed and flown. Challenges included subsystem integration, thermal environments and severe loads (including water impact), sometimes resulting in hardware attrition. Several of the subsystems evolved during the program through design changes. These included the thermal protection system, range safety system, parachute/recovery system, and others. Obsolescence issues occasionally required component recertification. Because the system was recovered, the SRB was ideal for data and imagery acquisition, which proved essential for understanding loads and system response. The three main parachutes that lower the SRBs to the ocean are the largest parachutes ever designed, and the SRBs are the largest structures ever to be lowered by parachutes. SRB recovery from the ocean was a unique process and represented a significant operational challenge; requiring personnel, facilities, transportation, and ground support equipment. The SRB element achieved reliability via extensive system testing and checkout, redundancy management, and a thorough postflight assessment process. Assembly and integration of the booster subsystems was a unique process and acceptance testing of reused hardware components was required for each build. Extensive testing was done to assure hardware functionality at each level of stage integration. Because the booster element is recoverable, subsystems were available for inspection and testing postflight, unique to the Shuttle launch vehicle. Problems were noted and corrective actions were implemented as needed. The postflight assessment process was quite detailed and a significant portion of flight operations. The SRBs provided fully redundant critical systems including thrust vector control, mission critical pyrotechnics, avionics, and parachute recovery system. The design intent was to lift off with full redundancy. On occasion, the redundancy management scheme was needed during flight operations. This paper describes some of the design challenges, how the design evolved with time, and key areas where hardware reusability contributed to improved system level understanding
