With the wide support for object serialization in object-oriented programming languages, persistent objects have become common place and most large object-oriented software systems rely on extensive amounts of persistent data. Such systems also evolve over time. Retrieving previously persisted objects from classes whose schema has changed is however difficult, and may lead to invalidating the consistency of the application. The ESCHER framework addresses these issues through an IDE-integrated approach that handles class schema evolution by mana ....etc

ABSTRACT
In today s business where speed is of essence, an iterative development approach that
allows the functionality to be delivered in parts has become a necessity and an effective
way to manage risks. In an iterative process, the development of a software system is done
in increments, each increment forming of an iteration and resulting in a working system. A
common iterative approach is to decide what should be developed in an iteration and then
plan the iteration accordingly. A somewhat different iterative is approach is to ....etc

this seminar describes steps involved in the manufacturing process of semicrystalline thermoplastic matrix composites. The model relates the temperature and pressure applied during processing to a) the flow of the matrix into the fiber tow, b) the formation of contact and bond between adjacent plies, and c) the crystallinity. The results of the model were verified by tests performed with PEEK 150P polymer and APC-2 graphite/PEEK composite. ....etc

Estimation of Defects Based on
Defect Decay Model: ED3M
Abstract:

An accurate prediction of the number of defects in a software product during system testing contributes not only to the management of the system testing process but also to the estimation of the product s required maintenance. Here, a new approach, called Estimation of Defects based on Defect Decay Model (ED3M) is presented that computes an estimate the defects in an ongoing testing process. ED3M is based on estimation theory. Unlike many existing approaches, the techniqu ....etc

Abstract
Scrum is a light weight process that can manage and control software and production development. It is a project management process. However instead of promoting the traditional analysis, design, code, test, deploy waterfall approach , whereby large requirements documents, analysis documents etc are created, scrum requires very low artifacts. It concentrates on important: managing a project or writing software that produces business value. Scrum revolves around the ethos of simplicity, resulting in delivery of something tha ....etc

Software Development Process Models
INTRODUCTION
There is various software development approaches defined and designed which are used/employed during development process of software, these approaches are alsoreferred as Software Development Process Models.
Each process model follows a particular life cycle in order to ensure success in process of software development.
A software development process, also known as a software development life cycle (SDLC), is a structure imposed on the development of a software product. Simil ....etc

Software systems come and go through a series of passages that account for their inception,
initial development, productive operation, upkeep, and retirement from one generation to
another. This article categorizes and examines a number of methods for describing or modeling
how software systems are developed. It begins with background and definitions of traditional
software life cycle models that dominate most textbook discussions and current software
development practices. This is followed by a more comprehensive review of the alternative ....etc
