Efforts to build systems to support the complex social reality of cooperative work need both a grounding in the social i.e., a rich abstract basis for understanding work, and a bridging link between the social and the technical to provide new insights into how to approach designing systems based on this understanding. We propose Anselm Strauss’ (1993) Theory of Action as a candidate from which ...

I wish to address development of theoretical framework by improving and combining currently existing methodologies and techniques. I also wish to adapt new approaches based on dynamical systems theories that have not been used to enhance predictability in the past. My overall approach will involve Eulerian and Lagrangian descriptions of the probablity density funtion evolution, identification a...

Regression models are often required for controlling production processes by predicting parameter values. However, the implicit assumption of standard regression techniques that the data set used for parameter estimation comes from a stationary joint distribution may not hold in this context because manufacturing processes are subject to physical changes like wear and aging, denoted as process ...

We present data-dependent learning bounds for the general scenario of non-stationary nonmixing stochastic processes. Our learning guarantees are expressed in terms of a datadependent measure of sequential complexity and a discrepancy measure that can be estimated from data under some mild assumptions. We also also provide novel analysis of stable time series forecasting algorithm using this new...

We take up the challenge of forecasting out-of-sample monthly returns on stock market indices. Recent contributions show that a wide range of popular predictors poorly forecast the US equity premium when the performance is compared to the average predictor. We revisit these findings focusing on three aspects. First, we report results for four major stock markets: US, UK, Germany and Japan. We f...

Abstract This paper proposes a new, physically based, and mathematically consistent method for predicting the evolution of existing landslides first-failure phenomena based on slope displacement measurements. The is latest step in long-term research program and, as such, uses preliminary framework introduced two previous papers. first characterizes movements through limited number trends, secon...

portfolio theory assumes that investors accept risk. this means thatin the equal rate of return on the two assets, the assets were chosenthat have a lower risk level. modern portfolio theory is accepted byinvestors who believe that they are not cope with the market. sothey keep many different types of securities in order to access theoptimum efficiency rate that is close to the rate of return o...
