floorplanning is an important step in physical design of vlsi circuits. it is used to plan the positions of a set of circuit modules on a chip in order to optimize the circuit performance. however, modern floorplanning takes better care of providing extra options to place dedicated modules in the hierarchical designs to align circuit blocks one by one within certain bounding box for helping seq...

Alignment is among the principal constraint families found in Optimality Theoretic approaches to phonology. Much of the discussion in the recent literature (Eisner 1997; Kager 2001, 2005; McCarthy 2003; Buckley 2009), however, has focused on difficulties arising within the standard Generalized Alignment (McCarthy and Prince 1993a, 1993b) framework. In this article, I propose a definition of ali...

The main purpose of this work is the comparison of several objective functions for optimization of the vertical alignment. To this end, after formulation of optimum vertical alignment problem based on different constraints, the objective function was considered as four forms including: 1) the sum of the absolute value of variance between the vertical alignment and the existing ground; 2) the su...

Recent phonological accounts of liaison (e.g., Booij (1986); Encrevé (1988); Tranel (1994); Tranel (1995) have relied heavily on rules and constraints involving syllable structure. Such an approach potentially meshes well with Selkirk’s (1974) study which accounts for the grammatical distribution of liaison in terms of phonological words. However, there is evidence that prosodic constraints are...

This paper studies interference alignment scheme and minimum mean square error (MMSE) improvement in Internet of Things (IoT)-oriented cognitive systems, where IoT devices share the licensed spectrum by cognitive radio in spectrum underlay. Target to manage the inter-tier interference caused by cognitive spectrum sharing as well as ensure an MMSE at receivers, the interference alignment algorit...
