We define LCL decompositions of the plane and investigate the advantages of using such decompositions in the context of digital topology. We show that discretization schemes based on such decompositions associate, to each LCL tiling of the plane, the digital model preserving the local topological structure of the object. We prove that for any LCL tiling of the plane, the digital model is necess...
Nowadays, LCL filters utilization to suppress the grid-connected inverter switching harmonics is expanding and various methods such as capacitor current active damping scheme could be investigated to damp out these harmonics. However, the computational delays including control system, and PWM switching delays have significant effect on damping system stability. In most of LCL filter parameter d...
(ii) the DNA of Ch-LCL contained sequences homologous to approximately 35 to 45% of human EBV; (iii) Ch-LCL contained an intranuclear antigen, Ch-NA, that could be identified with some chimpanzee or orangutan serum in anticomplimentary immunofluorescence assays; and (iv) treatment of Ch-LCL with iododeoxyuridine resulted in expression of new antigenic activity that reacted with EA+ but not EAhu...
کاربرد مبدلهای الکترونیک قدرت در توربینهای بادی، منجر به تولید هارمونیک و میانهارمونیک میشود. همچنین کلیدزنی مبدلها، منجر به اغتشاش توان اکتیو خروجی توربینها میشود. برهمکنش هارمونیکی مزارع بادی با شبکه بالادستی، انتشار هارمونیکها در آن و تقویت این انتشارها بهواسطه تشدیدهای موجود در کابلهای انتقال زیرزمینی، میتواند به افزایش مشکلات کیفیت توان منجر شود. این مقاله روشی را برای مطالعه و...
This paper analyses the characteristics of LCL filter in active power filter (APF) and provides an accurate for mula to determine the resonant frequency of system. Based on a single-phase equivalent circuit model, a systematic approach to design APF with LCL filter is proposed. Total inductance is determined by the capability of APF. Moreover, damping ratio, resonant frequency and attenuation d...
This paper establishes an LCL-filters design and control for three-phase grid inverter. The crucial object is to conquer optimum damping with a required system control bandwidth for the LCL-filter. This control technique is achieved by using Bacteria Foraging Optimization. Mathematical analysis has been introduced to investigate the steady-state and dynamic performances of the overall system. T...
Epstein-Barr virus (EBV) super-enhancers (ESEs) are essential for lymphoblastoid cell (LCL) growth and survival. Reanalyses of LCL global run-on sequencing (Gro-seq) data found abundant enhancer RNAs (eRNAs) being transcribed at ESEs. Inactivation of ESE components, EBV nuclear antigen 2 (EBNA2) and bromodomain-containing protein 4 (BRD4), significantly decreased eRNAs at ESEs -428 and -525 kb ...
On the Language Design and Semantic Foundation of LCL a Larch C Interface Speci cation Language The specialization of a speci cation language to a particular programming lan guage is an important characteristic of module interface speci cation languages MISL s The only well developed MISL s are the Larch interface languages and among these LCL a Larch C interface speci cation language would see...
INTRODUCTION: Posterior tibial tendon dysfunction (PTTD) is the most common cause of the adult flatfoot and is treated with a variety of operations such as tendon transfers, ligament reconstruction, osteotomies, and arthrodeses. Lateral column lengthening with a calcaneocuboid fusion (LCL) (Fig. 1) has been reported for treatment of PTTD in adults (1) to correct the deformity, while minimizing ...
