Generalization of semi-regular modules

A new type of modulation for television transmitters which was proposed recently is investigated. The relations referring to the operation of the network, of the modulator, and of the radio-frequency amplifier tubes are derived as well as the expressions for the sideband attenuation characteristic. It is concluded from the results that the claims made for the new modulation system are exaggerated. The modlator tubes are required to have a very high emission. This fact will limit the application of the new type of modulation to modulator tubes having thoriated-tungsten filaments and consequently to relatively small power, since at present tubes of this type are built for low or medium output power only. The efficiency of the new modulation system is essentially the same as that of grid-bias modulation. Contrary to expectations, the band width is not materially greater than that which is attainable with grid-bias modulation. This is due to the sideband clipping taking place in the quarter-wave line connecting the modulator tubes with the remainder of the network. The modulation characteristic is straighter than is customarily obtainable with grid-bias modulation; this is achieved by working the modulator grids in the positive region only, a mode of operation which requires high driving power and modulator grids capable of dissipating that power. The output capacitance of the modulator tubes is substantially smaller than the output capacitance of a grid-bias-modulated amplifier, but so is also the damping effect contributed by the internal resistance of the modulator.

Functional module identification in biological networks may provide new insights into the complex interactions among biomolecules for a better understanding of cellular functional organization. Most of existing functional module identification methods are based on the optimization of network modularity and cluster networks into groups of nodes within which there are a higher-than-expectation number of edges. However, module identification simply based on this topological criterion may not discover certain kinds of biologically meaningful modules within which nodes are sparsely connected but have similar interaction patterns with the rest of the network. In order to unearth more biologically meaningful functional modules, we propose a novel efficient convex programming algorithm based on the subgradient method with heuristic path generation to solve the problem in a recently proposed framework of blockmodel module identification. We have implemented our algorithm for large-scale protein-protein interaction (PPI) networks, including Saccharomyces cerevisia and Homo sapien PPI networks collected from the Database of Interaction Proteins (DIP) and Human Protein Reference Database (HPRD). Our experimental results have shown that our algorithm achieves comparable network clustering performance in comparison to the more time-consuming simulated annealing (SA) optimization. Furthermore, preliminary results for identifying fine-grained functional modules in both biological networks and the comparison with the commonly adopted Markov Clustering (MCL) algorithm have demonstrated the potential of our algorithm to discover new types of modules, within which proteins are sparsely connected but with significantly enriched biological functionalities.

This paper presents a new controller of a microgrid connected converter to reduce harmonic components to ensure high quality of electrical power, although the microgrid connected inverter with an LCL filter has the ability of attenuating the higher order harmonics. The major advantage of the proposed controller is that it can attenuate both the higher and lower order harmonics with a small size line filter which minimize both the physical size and cost of the system. Fast Fourier transform (FFT) and total harmonic distortion (THD) of the output voltage waveform is measured and compared to the preset tolerance level. The controller uses new type of modulation by using feed-forward control instead of feedback control to obtain quick response. Comparison of different output waveforms of converter using different modulation like space vector modulation (SVM), advanced pulse width modulation (PWM) and the proposed modulation are presented. The proposed controller using feed-forward scheme can effectively suppress the distortion arises from the grid voltage harmonics as well as regulate for different load conditions and power generation. MATLAB/Simulink is used for simulation of the entire system.

New types of modules named Fully Small Dual Stable Modules and Principally Small Dual Stable are studied and investigated. Both concepts are generalizations of Fully Dual Stable Modules and Principally Dual Stable Modules respectively. Our new concepts coincide when the module is Small Quasi-Projective, and by considering other kind of conditions. Characterizations and relations of these concepts and the concept of Small Duo Modules are investigated, where every fully small dual stable R-module M is small duo and the same for principally small dual stable.

The MATRIX platform integrates new types of modules for handling and alignment capability and this represents two new and innovative aspects for multi-beam lithography. Results on performances in terms of robustness of the different modules in real manufacturing conditions, including the interface of the MATRIX platform with the SOKUDO DUO track will be reported. A new type of alignment solution was developed by MAPPER. This paper will show the first results on alignment sensor repeatability. Preliminary results on the overlay performance of the MATRIX platform will be presented and discussion will be engaged to position the MAPPER alignment concept with respect to the ITRS roadmap expectations.

Let R be an associative ring with identity and let M be a unitary left R-module. In this paper, we introduce a ⊕-Jacobson-supplemented module (for short ⊕-J-supplemented), as a generalization of J-supplemented module. We state the main properties of a ⊕-J-supplemented modules and supplying by examples and remarks for these module and several properties of this modules are given. Also we introduce weakly ⊕-J-supplemented modules and give a characterization of weakly ⊕-J-supplemented modules a conditions under which the direct sum of weakly ⊕-J-supplemented modules is weakly ⊕-J-supplemented are given. We define a cofinitely ⊕-J-supplemented modules (for short, cof-⊕-J-supplemented) and some type of modules that are related to cof-⊕-J-supplemented module and prove properties of this type of modules. Also we discuss the relation between them with examples and remarks.
