This paper describes a method to implement the functionality of shared passive packages on top of a logical distributed memory — Linda. From a shared passive package a compiler can construct a new normal package that replaces the shared passive package. The new package contains the same subprograms and is extended with abstract data structures mapping Ada objects onto the storage units of Linda...
Hemagglutination inhibition, enzyme-linked immunosorbent assay (ELISA), and passive latex agglutination were used to test 495 human serum samples for determination of rubella immunity. Overall agreements for immune status were as follows: hemagglutination inhibition versus ELISA, 94.7% (469 of 495); hemagglutination inhibition versus passive latex agglutination (1:10 dilution), 99.2% (491 of 49...
in the area of vocabulary teaching and learning although much research has been done, only some of it has led to effective techniques of vocabulary teaching and many language learners still have problem learning vocabulary. the urge behind this study was to investigate three methods of teaching words. the first one was teaching words in context based on a traditional method of teaching that is,...
Background & Objectives: Air pollution is one of the most important environmental problems in large cities. Aromatic hydrocarbons as volatile organic compounds (VOCs) have been listed in Hazardous Air Pollutants (HAPs) by Environmental Protection Agencies (EPA). The aim of this study is Passive sampling and determination of aromatic hydrocarbons (AHs) toluene, xylene and ethylbenzene using ...
Aims: Reducing the city's vulnerability in times of crisis and emergencies is part of the urban design mission. Hence, passive defense measures have been developed to reduce the vulnerability of cities in times of crisis. The purpose of this study was to identify the factors affecting passive defense in the performance of urban spaces in the area of Enghelab Square in Tehran. Methodology: This ...
This paper presents a passive islanding detection method based on means of a neuro-fuzzy approach for wind turbines. Several methods based on passive and active detection scheme have been proposed. While passive schemes have a large Non detection zone (NDZ), concern has been raised on active method due to its degrading power quality effect. Reliably detecting this condition is regarded by many ...
In this work, a new strategy to design passive energy dissipation systems for vibration control of large structures is presented. The method is based on the equivalence between passive damping systems and fully decentralized static velocity-feedback controllers. This equivalence allows to take advantage of recent developments in static output-feedback control design to formulate the passive-dam...
This paper proposes a method in order to render passive nonlinear affine-incontrol discrete-time systems. The methodology is based on the discrete-time version of the speed-gradient (SG) algorithm. For the application of the SG algorithm, quasiV -passive and feedback quasi-V -passive systems are introduced. Two kinds of feedback laws rendering the system locally quasi-V -passive are obtained: a...
A reverse passive agglutination method was developed to detect soluble antigens of Legionella spp. By this method Legionella antigens were detected in urine specimens from 14 of 15 antigenuric patients with clinically diagnosed Legionnaires disease and in none of 263 urine samples from healthy subjects or patients with urinary tract infections. Intra-genus cross-reactivity was observed only bet...
