Requirements elicitation describes the activities needed to determine the requirements of a software system. It is essential to the success of a software development project. Requirements elicitation techniques are used by requirements engineers to discover the information needed to build systems that will satisfy the needs of stakeholders. This paper presents different types of software system...

Detailed road maps are essential for efficient routing of vehicles. However, available data on roads is not always sufficient to support efficient routing, especially in the domain of agricultural vehicles, where route networks are not maintained by official mapping agencies. Efficient route planning can help reducing the cost of agricultural operations such as harvesting. We propose an approac...

This research opens up for consideration the topic of a generalized simulation Applications Programming Interface. Discussion evolves around representation of one phenomenon essential to such an Interface, which is the widely used Line-of-Sight methodology. The research describes an initial set of line of sight (LOS) attributes necessary for a generalized Applications Programming Interface. Det...

A small number of general visual attributes have been recognized as essential in describing image quality. These include micro-uniformity, macro-uniformity, colour rendition, text and line quality, gloss, sharpness, and spatial adjacency or temporal adjacency attributes. The multiple-part International Standard discussed here was initiated by the INCITS W1 committee on the standardization of of...

One of the most challenging goals of recommender systems is to infer the preferences of users through the observation of their actions. Those preferences are essential to obtain a satisfactory accuracy in the recommendations. Preference learning is especially difficult when attributes of different kinds (numeric or linguistic) intervene in the problem, and even more when they take multiple poss...

The importance of accurate estimation of student’s future performance is essential in order to provide the student with adequate assistance in the learning process. To this end, this research aimed at investigating the use of Bayesian networks for predicting performance of a student, based on values of some identified attributes. We presented empirical experiments on the prediction of performan...

This paper used in estimation algorithm, for two essential data mining task. i.e classification&regression. it learning to occur the difficult error as octave error,the whole learning process is estimation of perceptual tempo.where the data labels are respect to the propagation on similarity graph constructed based on the feature representation. This paper experiment consider lastFM in 2011.the...

This paper introduces research being carried out into the measurement of the quality of e-commerce systems. Considerable work has been done on software metrics in the last few decades but e-commerce specific metrics seem only applicable to already deployed systems. It is proposed that a set of metrics is needed, which can be applied from the earlier stages of E-Commerce system development to im...

Real-world data collections are often heterogeneous (represented by a set of mixed attributes data types: numerical, categorical and fuzzy); since most available similarity measures can only be applied to one type of data, it becomes essential to construct an appropriate similarity measure for comparing such complex. In this paper, a framework of new and unified similarity measures is proposed ...

ion Abstraction means to focus on the essential features of an element or object in OOP, ignoring its extraneous or accidental properties. The essential features are relative to the context in which the object is being used. Grady Booch has defined abstraction as follows: “An abstraction denotes the essential characteristics of an object that distinguish it from all other kinds of objects and t...
