TL;DR: Empirical analysis is carried out to validate object-oriented design metrics for defects estimation and indicates that SLOC, WMC, CBO and RFC are reliable metrics for defect estimation.
Abstract: Problem Statement: Object-oriented design has become a dominant method in software industry and many design metrics of object-oriented programs have been proposed for quality prediction, but there is no well-accepted statement on how significant those metrics are. In this study, empirical analysis is carried out to validate object-oriented design metrics for defects estimation. Approach: The Chidamber and Kemerer metrics suite is adopted to estimate the number of defects in the programs, which are extracted from a public NASA data set. The techniques involved are statistical analysis and neuro-fuzzy approach. Results: The results indicate that SLOC, WMC, CBO and RFC are reliable metrics for defect estimation. Overall, SLOC imposes most significant impact on the number of defects. Conclusions/Recommendations: The design metrics are closely related to the number of defects in OO classes, but we can not jump to a conclusion by using one analysis technique. We recommend using neuro-fuzzy approach together with statistical techniques to reveal the relationship between metrics and dependent variables, and the correlations among those metrics also have to be considered.

TL;DR: This work presents a framework that allows the end-user to participate in the entire process of designing their own objects, from the initial concept stage to the production of a new real-world object that fits well with the existing complementary objects.
Abstract: The products that we use everyday are typically designed and produced for mass consumption. However, it is difficult for such products to satisfy the needs of individual users. We present a framework that allows the end-user to participate in the entire process of designing their own objects, from the initial concept stage to the production of a new real-world object that fits well with the existing complementary objects. We advocate using a single photo as a rough guide for the user to sketch a new customized object that does not exist in the photo. Our system provides a 2D interface for sketching the outline of the new object and annotating certain geometric properties of it directly on the photo. We introduce a Modified Lipson optimization method for generating the 3D shape. We design a variety of real-world everyday objects that are complementary to the existing objects and environment in the photo. We show that novice users can learn and create new objects with our system within minutes.

TL;DR: In this article, instructions are generated to manipulate target objects and relationships in a relational database when a source object having a one-to-many relationship of privately owned type with the target objects is manipulated.
Abstract: Instructions are generated to manipulate target objects and relationships in a relational database when a source object having a one-to-many relationship of privately owned type with the target objects is manipulated. To generate instructions, mapping meta-data is used which contains information as to how object classes of the object model map to tables in the database and how relationships map to foreign keys.

TL;DR: This paper tackles the problem of recognizing everyday objects that are useful for a personal robotic assistant in fulfilling its tasks, using a hierarchical multi-modal 3D-2D processing and classification system.
Abstract: In this paper we present a comprehensive object categorization and classification system, of great importance for mobile manipulation applications in indoor environments. In detail, we tackle the problem of recognizing everyday objects that are useful for a personal robotic assistant in fulfilling its tasks, using a hierarchical multi-modal 3D-2D processing and classification system. The acquired 3D data is used to estimate geometric labels (plane, cylinder, edge, rim, sphere) at each voxel cell using the Radius-based Surface Descriptor (RSD). Then, we propose the use of a Global RSD feature (GRSD) to categorize point clusters that are geometrically identical into one of the object categories. Once a geometric category and a 3D position is obtained for each object cluster, we extract the region of interest in the camera image and compute a SURF-based feature vector for it. Thus we obtain the exact object instance and the orientation around the object's up-right axis from the appearance. The resultant system provides a hierarchical categorization of objects into basic classes from their geometry and identifies objects and their poses based on their appearance, with near real-time performance. We validate our approach on an extensive database of objects that we acquired using real sensing devices, and on both unseen views and unseen objects.

TL;DR: In this paper, a system and method for method facilitating design-time data binding of business object(s) and/or web service (s) is provided, where developers can specify their own class(es) that do not require specific inheritance, interface implementation or default public constructors.
Abstract: A system and method for method facilitating design-time data binding of business object(s) and/or web service(s) is provided. Developer(s) can specify their own class(es) that do not require specific inheritance, interface implementation or default public constructors. The system includes a binding component that generates control information associated with control(s) based, at least in part, upon binding information associated with an entity (e.g., object, business object and/or web service). The system further includes a control generator that generates control(s) of a form associated with the entity based upon the generated by the binding component. The binding component can utilize public property(ies) of the entity (e.g., object, business object and/or web service). The entity can represent a hierarchy of objects that drill down (e.g., endlessly), including circular relationships. At design-time, a user (e.g., developer) can drag the root of an object (e.g., a business object and/or a web service) onto a form. Control(s) associated with the form are created by the system based on a schema of the object.
