Agrarian Change and Social Mobility in Tamil Nadu

This is a study of social mobility over 25 years in six villages in the former Tiruchy District in Tamil Nadu. The two most important external drivers are local industrialization and social policy in a broad sense. In a mainly descriptive analysis, it is shown that the overall effect seems to be a centripetal tendency in agrarian structure, with tendencies towards a strengthened position for famil

Making MLSD-decisions on some individual symbols in a sequence by thresholding the matched filter output

We present a detector that, by thresholding the output of the matched filter, gives MLSD-decisions on binary, antipodally modulated symbols that have been corrupted by intersymbol interference and additive Gaussian noise. The detector is simple in structure, consisting of a whitened matched filter and two variable thresholds for each symbol to be detected. The detector will make decisions on some,

An integrated approach to Archaeology: From the Fieldwork to Virtual Reality Systems

The visualisation of an archaeological landscape passes through its representation, interpretation and reconstruction. Its various and complex aspects can be described just through an integrated approach of disciplines, data and technologies. Two directions have been undertaken by our research team: a narrative approach and a geographical-spatial one. The narrative approach to cultural data is foc

Topographical data for delineation of agricultural management zones.

The aim of this study was to delineate management zones by using topographical data, and to investigate how these management zones relate to soil parameters and yield. Elevation, as well as soil and yield data, were sampled in the field. Digital elevation models have been created, and the topographical parameters of slope, aspect and drainage area, estimated. Management zones have been delineated

Sensor Fusion for Motion Estimation of Mobile Robots with Compensation for Out-of-Sequence Measurements

The position and orientation estimation problem for mobile robots is approached by fusing measurements from inertial sensors, wheel encoders, and a camera. The sensor fusion approach is based on the standard extended Kalman filter, which is modified to handle measurements from the camera with unknown prior delay. A real-time implementation is done on a four-wheeled omni-directional mobile robot, u

Challenges in Market-Driven Requirements Engineering - an Industrial Interview Study

Requirements engineering for commercial off-the-shelf software packages entails special challenges. This paper presents preliminary results from an empirical study investigating these challenges through a qualitative approach using semi-structured interviews. The survey is exploratory with the objective of eliciting relevant topics for further research. Seven employees at five software companies w
