A novel active feedback frequency compensation scheme is presented in this work. Based on the proposed technique, an amplifier with two main poles in its frequency bandwidth can be easily compensated by introducing a pole-zero pair in a local feedback. The proposed method is mathematically analyzed and then based on the derived formulations, a design procedure is established. The capability of ...

Projection methods support effective visualizations of multidimensional data. Linear projections are an important subclass, as they allow for interactive visual exploration of the data space and feature sensitivity analysis. The user interaction is usually based on an iterative modification of the projection matrix elements, for example, by the use of a star coordinate widget. However, such int...

With the use of subwavelength photolithography, some layouts can have low printability and, accordingly, low yield due to the existence of bad patterns even though they pass design rule checks. A reasonable approach is to select some of the candidate bad patterns as forbidden. These are the ones with a high yield impact or low routability impact, and these are to be prohibited in the design pha...

Plant layout design is related to the location of facilities (e.g. machines, departments) in a plant. They are known to greatly impact the system performance. Numerous research works related to facility layout have been published. A few literature reviews exist, but they are not recent or are restricted to certain specific aspects of these layout design. The literature analysis given here is re...

the integration of an approximate model and a clonal selection algorithm (csa) is considered to one of the most effective ways to solve complex optimization design problems in engineering. in this study, first, a process for developing an approximate model and the principles of clonal selection algorithms were presented. then, a variotherm temperature injection mold used to produce a large liqu...

The Locomotive Depot has a maintenance layout with 6 main lines as lines. of the facilities is also problem at Semarang Poncol locomotive depot because only 1 line can effectively carry out and repairs so this disadvantage dense queue locomotives wishing to be on duty carrying daily checks or monthly checks. that these 3 routes are often 2 which not maximized properly used place wait for repair...

We present an update on the lattice design of the electron ring of the Jefferson Lab Electron-Ion Collider (JLEIC). The electron and ion collider rings feature a unique figure-8 layout providing optimal conditions for preservation of beam polarization. The rings include two arcs and two intersecting long straight sections containing a low-beta interaction region (IR) with special optics for det...

In manufacturing-cell-formation research, a major concern is to make groups of machines into machine cells and parts part families. Extensive work has been carried out in this area using various models techniques. Regarding these ideas, paper, experiments with varying parameters the popular metaheuristic algorithm known as genetic have bi-criteria objective function: minimization intercell move...

Abstract The future scientific program at GSI needs a dedicated proton injector into the synchrotron SIS, in order to increase the proton intensity of the existing UNILAC/SIS12 combination by a factor of 70, resulting in 7x1012 protons in the synchrotron. A compact and efficient 352 MHz RFQ CH-DTL combination based on novel structure developments for RFQ and DTL was worked out. For DTL's operat...

Creating multiple layout alternatives for graphical user interfaces to accommodate different screen orientations for mobile devices is labor intensive. Here, we investigate how such layout alternatives can be generated automatically from an initial layout. Providing good layout alternatives can inspire developers in their design work and support them to create adaptive layouts. We performed an ...
