The paper emphasizes the importance of respecting manufacturers' and customers' perspectives during product design. In the paper is a description of a new systematic approach to product functions. The output of the approach is the creation of cumulative product functions where both of the perspectives are covered. The first part of the paper describes the current approaches to product functions. This is followed by analysis of the functions related to the manufacturer's perspective based on the Theory of Technical Systems. The next part of the paper describes the analysis of functions related to the customer's perspective. The last part concentrates on the cumulative functions themselves. The main advantages of the cumulative functions approach can be described in the following way. Firstly, better product design (more sensitive to manufacturer and customer), where respecting both perspectives can lead to important advantages on the market. For example: an engineering department can use the advantage of cumulative functions as a source for a morphologic matrix to define the product, etc. Secondly, the controlling department, which can use the cumulative functions and target price determination (also an output of the approach) as a base for the Target Costing method.

This paper describes a numerical procedure that uses solution structure method, atomic basis functions and a collocation technique. Solution structure method is based on the theory of R-functions. The solution of a boundary value problem is expressed in the form of formulae called solution structure which depends on three components: the first component describes the geometry of the domain exactly in analytical form, the second describes all boundary conditions exactly, while the third component is called differential component because it contains information about governing equation. Unknown differential component of the solution structure is represented by a linear combination of basis functions. Here, we propose to use atomic basis functions because of their good approximation properties. To determine the coefficients of linear combination in the solution structure, a collocation technique is used. Combination of atomic basis functions and solution structure method gives the meshfree method that can be applied for solving boundary value problems in domains of arbitrarily complex geometry with complex boundary conditions. This paper summarizes the main principles of the proposed method and presents its application to solution of the torsion problem. [ABSTRACT FROM AUTHOR]

The paper presents the Function Points (FP) method, which can be used for a preliminary effort estimation using limited information. Despite the potential for early use of the effort estimation, FP provides meaningful and relatively accurate results. The authors aimed to design Modified Function Points (MFP) methods based on regression model and analyze the influence of Value Adjustment Factor (VAF) on the estimation accuracy of the development effort. For research purposes was selected the ISBSG dataset. Subsequently, the original dataset was reduced according to data requirements and divided into two parts the training and the testing section (in ratio 2:1). The presented analysis was processed as a preparatory phase for further research in this area. Matlab toolboxes were used for the design and verification of discussed algorithms.

This research paper presents a five step algorithm to generate tool paths for machining Free form / Irregular Contoured Surface(s) (FICS) by adopting STEP-NC (AP-238) format. In the first step, a parametrized CAD model with FICS is created or imported in UG-NX6.0 CAD package. The second step recognizes the features and calculates a Closeness Index (CI) by comparing them with the B-Splines / Bezier surfaces. The third step utilizes the CI and extracts the necessary data to formulate the blending functions for identified features. In the fourth step Z-level 5 axis tool paths are generated by adopting flat and ball end mill cutters. Finally, in the fifth step, tool paths are integrated with STEP-NC format and validated. All these steps are discussed and explained through a validated industrial component. [ABSTRACT FROM AUTHOR]

The complexity of an algorithm is usually expressed using complexity functions and complexity classes, in this paper we present a method to reduce the work with multi-variable complexity functions to the work with one-variable complexity functions. We define five complexity classes for multi-variable complexity functions and then we prove some properties for these classes. [ABSTRACT FROM AUTHOR]

This paper presents how to use hints to force various approaches for optimization the execution times of stored procedures in Oracle Jig. The testing was made on an application of mobile telephony through execution of stored procedure PI/SQL which is processing telephone invoices on a database with a million recordings. Some system parameters have greatly influenced the performance of execution times of stored procedures and functions. [ABSTRACT FROM AUTHOR]

This paper presents specific aspects of the beam structures junctions nonlinear calculus. The substructuring method applied with the help of some high-performance numerical methods is considered the only way to study some high level stress zones. The working methodology has an original character and may be generalized to all structures with geometrical and material discontinuities. The stress state configurations obtained using the finite element method allow a correct evaluation of the safety coefficients and reliability of the analyzed structure. [ABSTRACT FROM AUTHOR]
