In this paper we consider feedback passive systems, de-ned as nonlinear systems that can be rendered (strictly) passive by means of state feedback. For feedback passive systems in a parametric normal form, we present an adaptive controller that eeectively \passiies" the system. The proposed control uses techniques of Speed-Gradient (S-G) methodology from the Russian literature. Stability result...

We present a graph coloring register allocator which uses an improved form of passive live range splitting to reduce the count of dynamic spill operations. Program structure is used to guide the global splitting of live ranges and to place split operations at infrequently executed portions of the program. We also optimistically reconsider spill decisions at certain points to potentially enable ...

We analyse new SCUBA-2 submillimeter and archival SPIRE far-infrared imaging of a z =1.62 cluster, Cl 0218.3−0510, which lies in the UKIDSS/UDS field of the SCUBA-2 Cosmology Legacy Survey. Combining these tracers of obscured star formation activity with the extensive photometric and spectroscopic information available for this field, we identify 31 far-infrared/submillimeter-detected probable ...

Dynamically stable biped robots mimicking human locomotion have received significant attention over the last few decades. Formerly, the existence of stable periodic gaits for straight walking of passive biped walkers was well known and investigated as the notion of passive dynamic walking. This study is aimed to elaborate this notion in the case of three dimensional (3D) walking and extend it f...

A shell-model version of Kraichnan’s @Phys. Rev. Lett. 72, 1016 ~1994!# passive scalar problem is introduced which is inspired by the model of Jensen, Paladin, and Vulpiani @Phys. Rev. A 45, 7214 ~1992!#. As in the original problem, the prescribed random velocity field is Gaussian and d correlated in time, and has a power-law spectrum }k m , where km is the wave number. Deterministic differenti...

In previous papers, a passive control implementation structure is proposed for mechanical systems interacting with physical environments. The proposed implementation structure enforces robust passivity of the closed-loop system, i.e. passivity is ensured in the presence of inaccurate force sensing and model uncertainties. In this paper, we conduct experiments to validate and demonstrate this ro...

Dynamic response of underground structures has always been a topic of concern for designers and researchers. The behavior of these complicated systems under blast loading is affected by various factors and parametric studies are required to investigate their significance. The importance of soil density around the underground structure through which, the waves of explosion of a penetrator bomb i...

This study investigates three factors that have been argued to define "canonical form" in sentence comprehension: Syntactic structure, semantic role, and frequency of usage. We first examine the claim that sentences containing unaccusative verbs present difficulties analogous to those of passive sentences. Using a plausibility judgment task, we show that a mixed group of aphasics performed sign...

This study is entitled Passive Clauses Argument Structure of Give Verbs in Corpus Contemporary American English (COCA). It concerned with the argument structure which mapped to grammatical relation. aimed recognize relations passive clauses have “give verbs”. library research. The data this were taken from (COCA) clauses. To collect data, documentation method and note-taking technique applied. ...
