Optimized Scheduling Algorithm for Energy-Efficient Wireless Network Transmissions

-- B T Geetha, M V Srinath and V Perumal

Nowadays, achieving ideal utility performance in energy harvesting networks is a constraint. In this paper, Energy-restricted Scheduling Algorithm (ESA) is proposed which jointly accomplishes the energy and makes power sharing decisions for packet broadcast. During the last decade, considerable effort has been made in the analysis of numerous scheduling algorithms for multi-access time sharing schemes. The unique classic for these systems is to view them as single-resource system. In this paper, the problem of erecting utility optimal scheduling algorithms in a discrete stochastic network is considered, where the communication links have time varying qualities and the nodes are powered by finite capacity energy storage devices but are capable of harvesting energy. In every time slot, the network decides how much new data to admit and how much power to allocate over each communication link for data transmission.

Generating a Complete and Precise Back Index for E-Books

--Vibhooti Markandey

An index (plural: indexes) is a list of words or phrases (headings) and associated pointers (locators) to where useful material relating to that heading can be found in a document. Generally, the books consist such back indexes for minimizing the effort and time to search certain topic or word. Manually generated such back indexes have certain flaws. This paper describes the back-index-tool for the generation of books in machine readable format, which minimizes the effort involved in generation of back index of book manually, reducing the redundancy of words in the generated back index. The aim of the paper is to construct precise and complete back index for E-books.

Risk Management in IT Sector: Opportunities and Challenges

--R K Meenakshi and D Arivazhagan

Risk management is not an end in and of itself, but rather a part of sound organizational practices that include planning, preparedness, program evaluation, process improvement and budget priority development. The value of risk management approach or strategy to decision makers is not in the promotion of a particular course of action, but rather in the ability to distinguish between various choices within the larger context. Establishing the infrastructure and organizational culture to support the execution of risk management is a critical requirement for achieving the goals.

Image Enhancement Techniques in the Spatial Domain: An Overview

--Deepa Raj and Pushpa Mamoria

Enhancement is the process of manipulating an image so that the resultant one is more suitable than the original for a specific application. Usually, the images taken by different cameras or devices are not suitable due to dull and less contrast. Using digital image processing, one can enhance or sharpen the image. Lots of techniques are available as first derivation technique like Sobel mask, second derivative technique like Laplace mask and many more. This paper highlights the different techniques of image enhancement and their importance in the spatial domain for the gray scale image.
