TL;DR: In this article, the efforts of SpaceWorks Engineering's advanced design team to develop a viable Mars architecture based on Project Constellation launch vehicles and related lunar transportation technologies are summarized, and an overall concept of operations is outlined.
Abstract: In 2004, President Bush announced a new U.S. Vision for Space Exploration that includes plans to return humans to the moon followed by human missions to Mars. While human Mars missions have been studied and analyzed for decades, the current technical and political environment presents mission designers with new objectives and constraints. Given the significant investment required to develop new launch vehicles, habitat systems, and supporting technologies for the preparatory lunar campaign, it is likely that those systems will serve as the centerpiece of any future Mars exploration architecture. This paper summarizes the efforts of SpaceWorks Engineering’s advanced design team to develop a viable Mars architecture based on Project Constellation launch vehicles and related lunar transportation technologies. All-chemical LOX/LH2 transfer vehicles are used. No in-situ resource utilization (propellant manufacture) has been assumed. An overall concept of operations is outlined. Details are provided on element masses, Earth-Mars transfer times, development and operations costs, and estimated mission reliability. Throughout this internally-funded effort, emphasis has been placed on maturing design tools and multidisciplinary processes in order to develop a useful national capability should formal studies of Mars architectures be undertaken.

TL;DR: This paper designs, implemented and demonstrated a prototype integrated sensing and command and control system that enables shared situational awareness and collaboration during response operations, and combines sensors, communications, and visualization and collaboration technologies, with all components being linked in (near) real-time.
Abstract: Emergency responders fighting blazes and flooding, law enforcement securing sites and crowds, and medical teams treating victims are typical scenarios during rapidly-evolving, catastrophic events. The larger the disaster, the more complicated becomes the situation as thousands of responders from hundreds of organizations participate in the response and relief efforts. Organizing, coordinating and commanding these efforts remains a significant technical challenge, as it requires timely collection and distribution of information under harsh environments. With guidance from operational partners in California's emergency response community, we have designed, implemented and demonstrated a prototype integrated sensing and command and control system that enables shared situational awareness and collaboration during response operations. The system architecture is based on net-centric and service-oriented paradigms, and combines sensors, communications, and visualization and collaboration technologies, with all components being linked in (near) real-time. The utility of this prototype system was evaluated through a field exercise that tested the technical performance of the system and assessed the impact of new technologies on current concept of operations. In this paper, we describe the design analysis, system architecture, core enabling technologies, and the field evaluations.

TL;DR: A mathematical model for the route-independent analysis of the capacity of flexible manufacturing systems based on a concept of operation types is provided and an example is provided both to illustrate the use of operationtypes and to highlight the differences between the traditional route-dependent and the proposed route- independent formulations of capacity constraints.
Abstract: In a job shop, because of large setup times, each operation is assigned to only one machine. There is no alternative routing. In a flexible manufacturing system, each manufacturing operation can often be performed on several machines. Therefore, with automated equipment, the capacity of a machine to perform certain operations is not independent of the capacity of other machines. Often, however, operations managers can use a route-independent answer to production planning questions. For example, how much can be produced of a certain part type and when are important capacity questions in business negotiations, when the detailed routing and scheduling are not yet of interest or cannot be known. This paper provides a mathematical model for the route-independent analysis of the capacity of flexible manufacturing systems based on a concept of operation types. An example is provided both to illustrate the use of operation types and to highlight the differences between the traditional route-dependent and the proposed route-independent formulations of capacity constraints. Some computational results are also given. Finally, a sensitivity analysis is developed to analyze the feasibility of production plans when production requirements and machine capacities can change.

TL;DR: This system would answer questions of limits of the aircrafts maneuverability and survivability in terms of its limitation concerning control system design and development of commercial fighter aircrafts, UAV's and Quad copters.
Abstract: In recent times, there has been a significant rise in usage of aircrafts in surveillance and reconnaissance missions. Not all the aircrafts survive the harsh testing conditions put forth by the enemy regions. Aircraft Survivability Analysis gives the measure of the chances of survival for different counter strategies. The mission would be recalculated if particular sortie does not fall within the physical boundary of the performance of an aircraft. This is required both for the success of the mission and the survivability of the aircraft in the harsh enemy conditions. A system is envisioned comprising of the accurate modeling of the physical world and the accurate model of control system. An interoperable system which can work seamlessly together will provide mission planners, System integrators, aeronautical/ aerospace engineers a milieu wherein the Control System designer who is found wanted as far as the physical world is concerned is given a system which can simulate the real world in lab conditions. To achieve this, we combine the two most promising environments prevalent in the industry today namely Systems tool kit for modeling the operational environment MATLAB and LabVIEW for modeling the control system environment. Using a Math script window of LabVIEW, we have designed the aircraft model and controlling the variables of an aircraft using a simulation loop of a LabVIEW. The different flight conditions were arrived using Orthogonal Array (OA) based on different Aircraft weight, Altitude, Mach number configurations. This attempts to span the aircrafts across the regimes in aircrafts flight envelope. A system comprising of both, with seamless UDP based connection between the two is developed to expedite the process of development of feasible control system design and verification which allows the aircrafts to undertake complex mission. This system we believe would answer questions of limits of the aircrafts maneuverability and survivability in terms of its limitation concerning control system design and development of commercial fighter aircrafts, UAV's and Quad copters.
