Some of the standard PICmicros have a comparator module, consisting of two comparators, both of which can be connected to PORTA in a variety of configurations. The internal voltage reference divider can be used with the comparators to establish thresholds. Additionally, one of the comparator inputs can be configured to the RA2 port allowing for the use of an external voltage reference. By combi...

This software package provides algorithms for analysis and design of saturation avoiding control systems. The design of linear controllers for linear, possibly multivariable or uncertain, plants is considered. To avoid a conservative design, the external signals are hard bounded in amplitude and rate. During the example sessions, only reference signals are considered as external signals, but th...

Plagiarism detection can be divided in external and intrinsic methods. Naive external plagiarism analysis suffers from computationally demanding full nearest neighbor searches within a reference corpus. We present a conceptually simple space partitioning approach to achieve search times sub linear in the number of reference documents, trading precision for speed. We focus on full duplicate sear...

H. W. Marsh's (1986) internal/external (I/E) frames of reference model posits that students* self-concepts result from simultaneous comparison of their competence to their peers' ability and their ability in other areas. The VE model failed to receive clear support with (a) subject-specific self-efficacy and (b) frame-specific self-concepts. Frame-specific selfconcepts were assessed by asking s...

SESSION OVERVIEW tt is widely accepted that price evaluations involve some form of comparisons. That is, when faced with a stimulus price, the consumer evaluates that price by comparing it with some form of comparison standard. This comparison standard is often referred to "reference price." Two basic forms of comparison standards have been proposed in the pricing literature: Internal reference...

The objective of this paper is to assess the capability of existing lighting simulation methods to predict the performance of complex fenestration systems, which are becoming a commonly used component in buildings construction domain. A specific experimental protocol was conducted to collect reliable reference data based on illuminance measurements inside a black box with (and without) one comp...

Because of the variations of the languages, the coverage of the references is very important to the reference based automatic evaluation of machine translation systems. We propose a method to extend the reference set of the automatic evaluation only based on multiple manual references and their syntactic structures. In our approach, the syntactic equivalents in the reference sentences are ident...

In internal and external quality assessment of clinical chemical analyses, the use of reference method values is prescribed in the Federal Republic of Germany as a measure of accuracy control. In the field of lipid analyses, reference methods are available for measuring total cholesterol and total glycerol in control sera. The reference measurement procedures are based on the highly accurate an...

This paper presents the comparison of four control strategies for the A/O WWTP configuration for simultaneous C, N and P removal. The control strategies: i) external COD-P control; ii) external recycle flow-P control; iii) nitrate control in the last anoxic reactor; iv) ammonia control in the last aerobic reactor, were combined with other common control loops to build different control structur...

Inactivated severe acute respiratory syndrome-associated coronavirus samples were used for an external quality assurance study within the World Health Organization SARS Reference and Verification Network and other reference institutions. Of 58 participants, 51 correctly detected virus in all samples > or =9,400 RNA copies per milliliter and none in negative samples. Commercial test kits signifi...
