Network-based optimization techniques for wind farm location decisions

This study aims to find appropriate locations for wind farms that can maximize the overall energy output while controlling the effects of wind speed variability. High wind speeds are required to obtain the maximum possible power output of a wind farm. However, balancing the wind energy supplies over time by selecting diverse locations is necessary. These issues are addressed using network-based models. Hence, actual wind speed data are utilized to demonstrate the advantages of the proposed approach.

To establish optimal reference values for recovered immune cell subsets, we prospectively investigated post-transplant immune reconstitution (IR) in 144 patients who received allogeneic stem cell transplantation (allo-SCT) and without showing any of the following events: poor graft function, grades II?IV acute graft-versus-host disease (GVHD), serious chronic GVHD, serious bacterial infection, invasive fungal infection, or relapse or death in the first year after transplantation. IR was rapid in monocytes, intermediate in lymphocytes, CD3+ T cells, CD8+ T cells, and CD19+ B cells, and very slow in CD4+ T cells in the entire patient cohort. Immune recovery was generally faster under HLA-matched sibling donor transplantation than under haploidentical transplantation. Results suggest that patients with an IR comparable to the reference values display superior survival, and the levels of recovery in immune cells need not reach those in healthy donor in the first year after transplantation. We suggest that data from this recipient cohort should be used as reference values for post-transplant immune cell counts in patients receiving HSCT.

A Survey of the Observability for Single Observer Passive Location

Strategic Study of CAE 2007, Volume 9, Issue 11, Pages 54-62
A basic requirement for passive state estimation using single observer is the existence of a unique tracking solution. This leads to the question of observability. The target state is observable over the time interval if, and only if, it is uniquely determined by the measurements taken in that interval. In this paper, the state-observability problem for passive target tracking by angle measurements is analyzed using three methods: the geometrical method, the elementary algebraic method and linear system method. The observability for target tracking with frequency measurements is also analyzed. Degree of observability is discussed. And a concise review of papers on observability analysis is presented.
