the model, because it works well with linear data storage type, such as tape. • Model relates very well to natural hierarchies, such as assembly lines and workers' organizations in the society. • This also applies in the case of works by one-to-many relationship. Disadvantages of Hierarchical Data Model • They needed to re-stored data in different individuals. • The database can be very slow when searching for information on subpages. • We no longer use linear memory environments, such as tape, so
disciplined approach. • Waterfall model works well for smaller projects where requirements are very well understood. • Progress of software development is visible. • In this model phases are processed and completed one at a time. Phases do not overlap. Disadvantages of WATERFALL MODEL. • Poor model for long and ongoing projects. • Time consuming • Not good model for complex and object oriented projects. • Once an application is in testing stage, it is very difficult to go back and change something that was

Peak widths rapidly increase with retention for isothermal conditions. For these reasons, isothermal temperature conditions are only suitable for a limited number of analyses. For example figure no 11 is isothermal temperature for as temperature programming chromatogram for n- alkanes on conditions of DB-1, 15 m x 0.25 mm i.d., 0.25 μm,100°C; Helium at 30 cm/sec
· Projects that consider quality more important than schedule or cost prefer this methodology. 2.2. Disadvantages of waterfall model: § You cannot go back and modify anything in the previous phases once the application reaches testing phase. § During the life cycle, software cannot be produced to work until the application is in the final stages. § High
Nowadays, environmental concerns as well as the sharp rise in the price of oil spark researchers interest towards issues pertain to hybrid and electric vehicles. Electric vehicles are more efficient and versatile than their counterpart; that is, internal combustion engine vehicles (ICEVs). Therefore, the electrification of vehicles can counteract the detrimental effects of ICEVs when in terms of environmental as well as energy issues. The new generation of electric vehicles allow interesting layout
is a useful statistical technique that has found application in fields such as face recognition and image compression, and is a common technique for finding patterns in data of high dimension. Technically, a principal component can be defined as a linear combination of optimally-weighted observed variables. In order to understand the meaning of this definition, it is necessary to first describe how subject scores on a principal component are computed. Principal component analysis is sometimes confused
We know that Software is a collection of executable programming code, associated libraries and documentations. Engineering on the other hand, is all about developing products, using well-defined, scientific principles and methods. Software engineering is concerned with all aspects of software production from its early stages of system specification through the maintenance of the system after delivering it. Software engineering as an engineering branch associated with the development of software product
CHAPTER 1 INTRODUCTION 1. INTRODUCTION 1.1Bipedal Robot:- The term bi-pedal robot refers to a robot that walks on two legs. In the recent years there has been much interest stimulated in dynamic walking in bipedal robotics and legged locomotion in general. Part of reason for this interest is the need for robot which can operate in human oriented environments. Human presents a very elegant model of locomotion to emulate. The Bipedal robots will operate in the human environment with much
CHAPTER -1 INTRODUCTION The outbreak of digital image processing in 1920’s has revolutionalised the communication process [l]. The images were the first language used by the humans for interaction. The images in the form of pictures were carved on stone which became the first language for communication and these carvings were available for the future generation. With the technical advancements in recent times; image processing techniques has became an important part of the communication system. From
