Improved PV Module Performance under Partial Shading Conditions
Energy Procedia, 2013 AbstractIn a typical series-connected photovoltaic module with three bypass diodes, not all of the energy generated by the individual cells in the module can be collected when one or more of the cells in the module are partially shaded. In this work, various photovoltaic (PV) module layouts are investigated, using both full-size solar cells and halved ...

Spider Diagrams: A Diagrammatic Reasoning System [PDF]
, 2001 Spider diagrams combine and extend Venn diagrams and Euler circles to express constraints on sets and their relationships with other sets. These diagrams can be used in conjunction with object-oriented modelling notations such as the Unified Modeling ...

PV array reconfiguration method under partial shading conditions
International Journal of Electrical Power & Energy Systems, 2014 Abstract This paper proposes a new reconfiguration method for photovoltaic arrays under partial shading conditions. With the application the method, the array can produce higher power by reconfigured connections of array. In the proposed method, each row of an array is formed by connecting the panels with close short circuit current levels as ...

Self-thinning and Community Persistence in a Simple Size-structured Dynamical Model of Plant Growth [PDF]
, 2005 This paper presents a size-structured dynamical model of plant growth. The model takes the form of a partial differential-integral equation and includes the effects of self-shading by leaves.

Molecular Oncology, EarlyView.CDK11 inhibition stabilises the tumour suppressor p53 and triggers the production of an alternative p21WAF1 splice variant p21L, through the inactivation of the spliceosomal protein SF3B1. Unlike the canonical p21WAF1 protein, p21L is localised in the cytoplasm and has reduced cell cycle‐blocking activity.

New constraints on data-closeness and needle map consistency for shape-from-shading [PDF]
, 1999 This paper makes two contributions to the problem of needle-map recovery using shape-from-shading. First, we provide a geometric update procedure which allows the image irradiance equation to be satisfied as a hard constraint.

LDAcoop: Integrating non‐linear population dynamics into the analysis of clonogenic growth in vitro
Molecular Oncology, EarlyView.Limiting dilution assays (LDAs) quantify clonogenic growth by seeding serial dilutions of cells and scoring wells for colony formation. The fraction of negative wells is plotted against cells seeded and analyzed using the non‐linear modeling of LDAcoop.

Efficient Photovoltaic System Maximum Power Point Tracking Using a New Technique
Energies, 2016 Partial shading is an unavoidable condition which significantly reduces the efficiency and stability of a photovoltaic (PV) system. When partial shading occurs the system has multiple-peak output power characteristics.
