Study on MPP mismatch losses in photovoltaic applications

2009
One of the major sources of losses in a photovoltaic (PV) system is the mismatch between the amounts of energy generated by two or more modules inside an array. This mismatch can be caused for instance by partial shading of the modules. This paper investigates the performance decrease of PV-modules under non-optimal irradiance conditions, and also some

Global mismatch of policy and research on drivers of biodiversity loss

Nature Ecology & Evolution, 2018
The United Nations 2030 Agenda for Sustainable Development calls for urgent actions to reduce global biodiversity loss. Here, we synthesize >44,000 articles published in the past decade to assess the research focus on global drivers of loss. Relative research efforts on different drivers are not well aligned with their assessed impact, and multiple ...

Loss of mismatch repair proteins in sebaceous gland tumors

Journal of Cutaneous Pathology, 2003
Background: Sebaceous gland neoplasms are rare tumors that are associated with visceral malignancies in patients with Muir–Torre syndrome (MTS). The majority of the MTS‐associated tumors reveal mutations in DNA mismatch repair (MMR) genes (most often hMSH‐2 and hMLH‐1) and microsatellite instability. The sebaceous gland lesions in patients with MTS can

Characterization of the parameter-mismatching effect on the loss of chaos synchronization

Physical Review E, 2002
We investigate the effect of the parameter mismatch on the loss of chaos synchronization in coupled one-dimensional maps. Loss of strong synchronization begins with a first transverse bifurcation of a periodic saddle embedded in the synchronous chaotic attractor (SCA), and then the SCA becomes weakly stable. Because of local transverse repulsion of the

AN ANALYTICAL MODEL FOR MISMATCH LOSSES IN PV ARRAYS

International Journal of Solar Energy, 1992
Variations in the I-V characteristics of photovoltaic modules can lead to significant power loss. This study deals with an analysis of series-string losses. The current parameter of a set of PV modules is considered as a random variable following the Weibull distribution. An analytical expression has been obtained to predict these losses. A preliminary

Minimizing mismatch loss in BIPV system by reconnection

2011 37th IEEE Photovoltaic Specialists Conference, 2011
Recently, building-integrated photovoltaic (BIPV) systems have become increasingly popular because they provide increased available space and have great environmental appeal. However, these systems may be adversely affected by shadows of surrounding buildings.

Endometrial Carcinomas With Subclonal Loss of Mismatch Repair Proteins

American Journal of Surgical Pathology, 2023
Subclonal loss of mismatch repair (MMR) proteins has been described in a small subset of endometrial carcinomas (ECs), but the genomic basis for this phenomenon has received limited attention. Herein, we retrospectively evaluated all ECs with MMR immunohistochemistry (n=285) for subclonal loss, and in those (n=6), performed a detailed clinicopathologic

Photovoltaic plant losses: spectral mismatch

Energy Materials
Understanding solar photovoltaic plant losses, including optical and electrical losses, is vital to developing mitigating strategies and ensuring the economic viability of solar projects. The most significant optical loss is spectral mismatch. Spectral mismatch losses include thermalization and transmission. Spectral mismatch accounts for approximately

Increasing morphological mismatch via category loss

2023
Abstract Morphological mismatch is the situation in which forms from one morphosyntactic category encode the functions of another, as with aspectual distinctions in Spanish verbs marked by mood forms. This chapter addresses the origin of such mismatches, which has not yet been studied.

Raman and Brillouin couplers with losses and phase mismatch

Journal of Modern Optics, 1999
We investigate nonlinear couplers whose operation is based on Raman or Brillouin scattering. A quantum approach is used. Strong coherent laser pumping is assumed and linearized Heisenberg-Langevin equations of motion are solved. The influence of linear coupling constants, losses and phase mismatches on the dynamical behaviour of the coupler is ...
