A lot of research has been carried out in the past by using association rules to build more accurate classifiers. The idea behind these integrated approaches is to focus on a limited subset of association rules. However, these integration approaches have not been tested yet within the context of transportation research. The aim of this chapter is therefore to evaluate the performance of an adap...
T-cell mediated cytotoxic responses to H-Y antigen require co-recognition of H-Y and H-2 gene products. F1 mael stimulating cells and target cells express H-Y antigen in association with both parental H-2 haplotypes. However, F1 females primed in vivo and challenged in vitro with F1 male cells lyse male target cells of F1 and only one parental H-2 haplotype. Thus, (CBA X B10)F1 females sensitiz...
This paper deals with the CBA/N mice, a strain bearing a genetic defect in their B-cell compartment. By using a previously described system we have been able to show that the immature cells of CBA/N mice are functionally indistinguishable from normal immature cells, in that both can be triggered to respond to thymus-independent (TI) antigens, provided they are supplied with helper T cells. When...
The continuing efforts in the 104th Congress to legislate requirements for cost-benefit analysis (CBA) and the revised Office of Management and Budget (OMB) guidelines for the conduct of such assessments during a regulatory rulemaking process highlight the need for a comprehensive examination of the role that CBA can play in agency decision-making. This paper summarizes the state of knowledge r...
Conversational agents have been widely used in education to support student learning. There recent attempts design and use conversational conduct assessments (i.e., conversation-based assessments: CBA). In this study, we developed CBA with constructed selected-response tests using Rasa—an artificial intelligence-based tool. was deployed via Google Chat formative assessment. We evaluated (1) its...
Five bacterial isolates were isolated from soils polluted with petroleum waste deposition from Cairo Oil Refining Company, Al-Qalyubia, Egypt. These isolates were grown on five concentrations (20, 100, 500, 1000, 2000μM) of 3-chlorobenzoic acid (3-CBA) as a sole carbon and energy source. The abilities of these isolates to degrade this chloroaromatic compounds have been investigated. The growth ...
This paper presents a new approach to the problem of verifying safety properties of concurrent programs with shared memory and interleaving semantics. Our method builds on and extends contextbounded analysis (CBA), in which thread interleavings are considered only up to K context switches. In a K-induction argument, the base case establishes that the property holds for the first K steps (first ...
The automotive engine performance is greatly affected by the calibration of its electronic control unit (ECU). The method for ECU calibration is traditionally done by trial-and-error. This traditional method consumes a large amount of time and money. To resolve this problem, casebased reasoning (CBR) is employed, so that an existing and effective ECU setup can be adapted to fit another similar ...
In recent years, extensive research has been carried out by focusing on association rules to build more accurate classifiers. These integrated approaches mainly focus on a limited subset of association rules, i.e. those rules where the consequent of the rule is restricted to the classification class attribute. This paper aims to contribute to this integrated framework by adapting the CBA (Class...
How to share responsibility for greenhouse gas emissions between consumers and producers is a highly sensitive question in international climate policy negotiations. Traditional ‘Production-Based Accounting’ (PBA), which assigns responisibility the region where are released, has frequently been challenged by ‘Consumption-Based (CBA) schemes that suggest generated produce traded goods services s...
