Total Cross Sections of Ti, V, Y, Ta, and W
Nuclear Science and Engineering, 1960Total neutron cross sections were measured by the transmission method for metal samples of Ti, V, Y, Ta, and W in the energy range from 0.002 to 0.285 ev. The data are in agreement, within experimental error, with the previously published data at energies for which a comparison can be made.

One of the main obstacles to solar power production is the problem of partial shading and irradiance variation. The degree to which these factors can diminish the performance of a photovoltaic (PV) system depends on the specific shading pattern, PV array topology, and the physical location of the shaded PV modules within the array.

Optimal total cross tied interconnection for photovoltaic arrays to reduce partial shading losses
2012 IEEE Power and Energy Society General Meeting, 2012The condition of having different irradiance levels among different photovoltaic modules in a photovoltaic array is called partial shading. Energy losses have been reported to occur due to partial shading. These losses could be reduced by reconnecting the modules of the array in such a way that the overall impact of partial shading on the array is ...

An Optimal Total Cross Tied Interconnection for Reducing Mismatch Losses in Photovoltaic Arrays
IEEE Transactions on Sustainable Energy, 2013A mismatch in a photovoltaic array implies differences in the I-V characteristics of the modules forming the array. This can lead to significant energy losses known as mismatch losses. The mismatch and the resulting losses can be reduced by altering the interconnection of the array. This paper proposes an optimal total cross tied interconnection, based

In the existing solar photovoltaic modules, cells are connected in series. The performance of the series-connected module degrades severely during partial shading condition. Further, the use of bypass diode causes multiple peak (local and global peaks) problem.

One of issues about array photovoltaic (PV) is partial shading conditions. It can cause mismatch between the modules, leading to undesirable effects such as reduction in power generated and hot spots. Partial shading is caused by passing clouds, tree shadows, nearby building, tower, poles, etc. So the power output is less than expected value. It is not

The Philippines, being a tropical country, has a high photovoltaic (PV) energy generation potential that can help meet demand due to impending power supply shortage in the coming years. One factor that limits solar PV generation is nonuniform illumination or partial shading.

Abstract Mismatch losses ignore the performance of individual photovoltaic (PV) modules and cut back most of the power from the PV array. These losses mainly due to partial shading condition (PSC), are caused by the reduction of spacing between PV modules, passing clouds, and near buildings, etc.

Measurements of the total reaction cross section for protons on Ti and B between 20 and 50 MeV
Canadian Journal of Physics, 1978Using a variation of a standard attenuation technique, total proton reaction cross sections (σR) have been measured for Ti and B at eight incident proton energies between 20 and 50 MeV at the University of Manitoba Cyclotron Laboratory. The Ti cross sections are presented along with existing reaction cross section data and are compared with optical ...
