Enhanced evolutionary computing based artificial intelligence model for web-solutions software reusability estimation

Abstract: Ensuring the aging resilient software design can be of paramount significance to enable faultless software system. Particularly assessing reusability extent of the software components can enable efficient software design. The probability of aging proneness can be characterized based on key OO-SM like cohesion, coupling and complexity of a software component. In this paper, aging resilient software reusability prediction model is proposed for object oriented design based Web of Service (WoS) software systems. This work introduces multilevel optimization to accomplish a novel reusability prediction model. Considering coupling, cohesion and complexity as the software characteristics to signify aging proneness, six CK metrics; WMC, CBO, DIT, LCOM, NOC, and RFC are obtained from 100 WoS software. The extracted CK metrics are processed for min–max normalization that alleviates data-unbalancing and hence avoids saturation during learning. The 10-fold Cross-validation followed by outlier detection is considered to enrich data quality for further feature extraction. To reduce computational overheads RSA algorithm is applied. SoftAudit tool is applied to estimate reusability of each class, while binary ULR estimates calculates (reuse proneness) threshold. Applying different classification algorithms such as LM, ANN algorithms, ELM, and evolutionary computing enriched ANN reuse-proneness prediction has been done. The performance assessment affirms that AGA based ANN model outperforms other techniques and hence can be used for earlier aging-resilient reusability optimization for WoS software design.

Towards a type theory for active objects

Abstract: A key property of object-oriented languages is that they promote software reuse through inter-changeability or plug compatibility of software components that conform to the same message-passing interface. A characterization of such an interface is a type, and can be viewed as a constraint on the behaviour of an object. An object that conforms to the type meets the constraint. A subtype, in this view, is simply a stronger constraint: all objects that conform to a subtype also conform to the supertype. The nature of these constraints may vary, however, as may the rules for determining when one type is a subtype of another. The choice of characterization will depend on the computational model of a particular language and the way in which objects interact. We seek to develop a notion of type that will serve to characterize concurrent, active objects whose behaviour may not conform to a strict client/server model of interaction and communication.

Patterns as objects in grace

Abstract: Object orientation and pattern matching are often seen as conflicting approaches to program design. Object-oriented programs place type-dependent behavior inside objects and invoke it via dynamic dispatch, while pattern-matching programs place type-dependent behavior outside data structures and invoke it via multiway conditionals (case statements). Grace is a new, dynamic, object-oriented language designed to support teaching: to this end, Grace needs to support both styles. We explain how this conflict can be resolved gracefully: by modelling patterns and cases as partial functions, reifying those functions as objects, and then building up complex patterns from simpler ones using pattern combinators. We describe the implementation of this design as an object-oriented framework, and a case study of its effectiveness.

Systems and methods for transporting physical objects from real physical life into virtual worlds

Abstract: Systems and methods for transporting physical objects from real physical life into virtual worlds. Briefly stated, the method includes receiving characteristic and structure data from an object constructed in the real world. The characteristic and structure data is obtained from the object using a plurality of sensors placed in the vicinity of the object to sense the characteristics and structure of the object. The characteristic and structure data of the object is used to produce code necessary to create an equivalent representation of the object in a virtual world.
