Grandmother, Mother and Daughter: Changing agency of Indian, middle-class women, 1908-2008

Covering one hundred years, this paper recounts the life stories of three generations of middle-class women of the New Delhi-based Kapoor family. By taking the methodological view that individuals born approximately at the same time, within the same class segment, and at the same cultural place will be shaped by the same historical structures so that their lives to some extent are synchronized into a gendered, generational experience, these three life stories are viewed as voices that reflect their respective generational class segments. In view of this, the paper uses the three life stories to discuss changes in women’s agency within the urban, educated, uppermiddle-class. Agency is here understood as control over resources, and it is argued that in order to understand changes in women’s agency, one should take into account the impact of both social, economic structures and cultural ideologies. When analysing the three life stories, the overall finding is that the granddaughter has had more control over her own life than her mother and grandmother. However, by acknowledging that cultural ideologies and social economic structures are not always synchronized, a nuanced and many-dimensional picture of twists and turns in these middle-class women’s degree and type of agency over time emerges

Design of a Solar Sail Mission to Mars

An evaluation of the design of the solar sail includes key areas such as structures, sail deployment, space environmental effects, materials, power systems, telemetry, communications, attitude control, thermal control, and trajectory analysis. Deployment and material constraints determine the basic structure of the sail, while the trajectory of the sail influences the choice of telemetry, communications, and attitude control systems. The thermal control system of the sail for the structures and electronics takes into account the effects of the space environment. Included also are a cost and weight estimate for the sail

Schottky-based band lineups for refractory semiconductors

An overview is presented of band alignments for small-lattice parameter, refractory semiconductors. The band alignments are estimated empirically through the use of available Schottky barrier height data, and are compared to theoretically predicted values. Results for tetrahedrally bonded semiconductors with lattice constant values in the range from C through ZnSe are presented. Based on the estimated band alignments and the recently demonstrated p-type dopability of GaN, we propose three novel heterojunction schemes which seek to address inherent difficulties in doping or electrical contact to wide-gap semiconductors such as ZnO, ZnSe, and ZnS

On-line replacement of program modules using AdaPT

One purpose of our research is the investigation of the effectiveness and expressiveness of AdaPT(1), a set of language extensions to Ada 83, for distributed systems. As a part of that effort, we are now investigating the subject of replacing, e.g., upgrading, software modules while the software system remains in operation. The AdaPT language extension provide a good basis for this investigation for several reasons: (1) they include the concept of specific, self-contained program modules which can be manipulated; (2) support for program configuration is included in the language; and (3) although the discussion will be in terms of the AdaPT language, the AdaPT to Ada 83 conversion methodology being developed as another part of this project will provide a basis for the application of our findings to Ada 83 systems. The purpose of this investigation is to explore the basic mechanisms to the replacement process. Thus, while replacement in the presence of real-time deadlines, heterogeneous systems, and unreliable networks is certainly a topic of interest, we will first gain an understanding of the basic processes in the absence of such concerns. The extension of the replacement process to more complex situations can be made later. This report will establish an overview of the on-line upgrade problem, and present a taxonomy of the various aspects of the replacement process

ESIM_DSN Web-Enabled Distributed Simulation Network

In this paper, the eSim(sup DSN) approach to achieve distributed simulation capability using the Internet is presented. With this approach a complete simulation can be assembled from component subsystems that run on different computers. The subsystems interact with each other via the Internet The distributed simulation uses a hub-and-spoke type network topology. It provides the ability to dynamically link simulation subsystem models to different computers as well as the ability to assign a particular model to each computer. A proof-of-concept demonstrator is also presented. The eSim(sup DSN) demonstrator can be accessed at http://www.jsc.draper.com/esim which hosts various examples of Web enabled simulations
