The Rover Sequencing and Visualization Program (RSVP) is a tool suite used for building command sequences for the Mars Science Laboratory rover Curiosity. RSVP was previously used for other missions and for in-house research projects and proposal efforts. RSVP has undergone extensive modifications and enhancements over previous versions in order to support more challenging requirements and to make it more adaptable for future missions. This paper will provide a brief overview of many of the specific enhancements made for the MSL mission.

Detecting and tracking unconstrained hands in videos is a basic technique for sign language recognition. In current hand detection methods, AdaBoost classifier based on Haar-like features is known to be fast and robust against scale change and rotation. However, its performance drops sharply when the background is complicated or the hand and other skin-color parts overlap. Insufficient training data also decreases the performance. This paper proposes a new training method for Haar-like features based AdaBoost classifier with insufficient data, and a hand detector integrating Haar-like features, skin-color and motion cue together. Also we present a novel hand tracking technique. Experimental results have shown that the proposed method obtains a promising detecting rate of 99.9%, and more than 97.1% of the tracked hands are extracted in proper size. In summary the proposed method is more robust than AdaBoost classifier against complicated background, scale change and rotation.

In this paper a Relational Oriented Systems Engineering and Technology Tradeoff Analysis (ROSETTA) framework is introduced for performing technology tradeoff and design studies with respect to the live, virtual and constructive mixes for aircrew training. This novel, efficient and model driven repeatable approach to the present and future problem of live / synthetic mixes on-board a real aircraft concentrates on relationships between elements in models to support capability based decisions. The methodology described provides a framework and factorization of a family of systems (FoS) architecture for tactical situation/mission scenario and evaluation of pilot response models. ROSETTA provides a more rigorous mathematical framework for conducting decision support and advances current model based systems engineering (MBSE) process for simulation and analysis of a complex system of systems (SoS) problem.

Before the Curiosity rover can perform its science activities for the day, such as driving, moving its robotic arm, or drilling, it first has to ensure that its actuators are within their allowable flight temperatures (AFTs). When the rover is awake, flight software uses heaters to warm up and maintain thermal zones at operational temperatures. However, Curiosity spends about 70% of its time sleeping, with the flight computer off, in order to conserve energy. Dream Mode is a special behavior that allows the rover to execute warm-up activities while sleeping. Using Dream Mode, actuators can be warmed up to their AFTs before the flight computer wakes up and uses them - saving power and improving operational efficiency. This paper describes the motivation behind Dream Mode, how it was implemented and tested on Curiosity, and the challenges and lessons learned along the way.

The paper is about the drastic transformation of the strategy and business model of the Russian information technological enterprise which incorporates autonomous but interrelated business units: in 2001 top management of the IBS Company made the decision to switch to the information technology services and consulting area. The creation of new capabilities was the transformation objective. Capability based approach was successfully applied to achieve the transformation goals. An “ES/SoS nuclear model” has been introduced to describe the transformation. The model represents the enterprise as the “hard business nucleus” or kernel (major business-agents, who really make the business), a “soft business shell” (non-material environment: governing media, competences, knowledge, etc. - intangible assets), and the “cloud of extended enterprise” (clients, partners, etc., interlinked by common “across”-business processes). The great majority of transformation activities and outcomes lie in the ES/SoS's “soft shell” which includes new capabilities, governing relations, competences, etc.
