Recognition of Unconstrained Handwritten Digits Using Feedforward MLP and Projection Profile
Abstract: AbstractThis paper presents a new approach to off-line handwritten numeral recognition using feedforward MLP and projection profile. Different writers have variations in their handwriting since each writer possesses own writing speed, own styles, sizes or positions for numeral or text. Recognition of handwritten numerals poses serious problems because of high variability in numeral shapes written by individuals. The performance of character recognition system depends heavily on what kind of features …

Widespread Dissemination of Library Resources through Remote Access
Abstract: AbstractPresently Libraries are providing a wide range of online resources to their users. They have named the means called “digital library” or “virtual library”. Consequently virtual library can be called as Internet based information retrieval system. The notion of “virtual library” is that any person who has a computer can access not only the resources of the library but also access diversity of information accessible on Internet, or on Intranet …

Investigations on PAPR Reduction using PTS Technique for OFDM Communication Systems
Abstract: AbstractOrthogonal Frequency Division Multiplexing (OFDM) is a spectral efficient technique for high data rate communication systems. It also provides robustness to multipath frequency selective fading but suffers from high peak-to-average power ratio (PAPR) and causes high power amplifiers to operate in the nonlinear region. In this paper partial transmit sequence (PTS) as PAPR reduction technique has been investigated. Mathematical modelling and Matlab simulation have been carried out to analyse its …

Intellectual Property Rights in LIS
Abstract: AbstractIn the world of intellectual creativity, the rights of the owners of copyright have taken a long time to be understood. The concept of copyright that it is the outcome of the hard labor of a creative person has been difficult for people to understand. Not long ago, people thought that they could use and enjoy the writings of an author, the music of a composer and the paintings of …

Hypothesis Analysis in Library and Information Science
Abstract: AbstractHypotheses can be regarded as suggestions of possible connections between actual facts or imagined ones. The question of the truth of hypotheses need not, therefore, always be raised. The necessary feature of a hypothesis, from this point of view, is that it should be stable in a determinate form, so that implications can be discovered by logical means.Keywords: Hypothesis and scientific method, need and purpose, collection of dataCite this ArticleRajaram …

PAPR Reduction using Selective Mapping Method for OFDM Communication Systems
Abstract: AbstractSelective mapping method (SLM) is one of the most important techniques used for peak-to-average power ratio (PAPR) reduction of orthogonal frequency division multiplexing (OFDM) communication system. It is simple in implementation, gives distortionless transmission and reduces PAPR significantly. Mathematical modelling and Matlab simulation have been carried out to analyse its performances. At of CCDF, PAPR values for OFDM signal without applying any reduction technique is 11.5, 11.8, 12.1, 12.4 and …

Capacity and BER Performance Analysis of Single Cell Massive MIMO with Various Precoding Techniques
Abstract: AbstractMassive Multi Input Multi Output (MIMO) is one of the promising technologies which will facilitate the 5th generation wireless communication system (5G) in the near future. It also goes by other names such as, large MIMO, hyper MIMO, full-dimension MIMO and ARGOS. In this technology the Base Station is incorporated with a large number of transmitting antennas (e.g., Hundreds, thousands). A large number of antenna help to focus the energy …

Library Resource Sharing and Networking
Abstract: AbstractLibraries in the past had only written or printed documents. Written documents are manuscripts. These documents are always kept away and are not shared with other libraries. The users are expected to visit the library for consultation. The other category; the books were also not loaned to everyone and they were seldom shared with other libraries. With the introduction of printing by movable types, books started appearing in good number …

Simulation of Differential Space Time Block Coding
Abstract: AbstractIn such a coherent system, the underlying assumption is that the channel does not change during one frame of data. Thus, it can also be interpreted as the frame length is chosen such that the path gain change during one frame is negligible. This is basically the quasi-static fading assumption that we have used so far. There is a bandwidth penalty due to the number of transmitted pilot symbols. Of …

Evaluation of System Study in Library and Information Science
Abstract: AbstractThe word ‘system’ has become a common term, often applied to things which seem large or complex. It is so frequently encountered, that it can become quite difficult to decide what it means even within a defined context. When a manufacturer of washing powder, computer programmers, doctors, economists, astronomers and ecologists use the same word, ‘system’, in describing their interests, can anyone be sure what they mean? What is the …

Performance Evaluation of Library and Information Centers
Abstract: AbstractTraditionally, libraries have been evaluated in terms of input or available resources, such as number of volumes, number of staff members, size of facilities, and so on. More recently, there has been a vigorous movement toward evaluating libraries according to their output of performance. This latter evaluation focuses on what was accomplished with the library’s resources. Many of the performance measures developed thus far have concentrated on such factors as …
