The document describes the TOPS (TOPS Offshore Production Systems) concept for offshore oil and gas production. TOPS aims to provide continuous production from appraisal through to refining using a ship-based system, eliminating conventional rigs and platforms. The system would include a moored tower and subsea template connected to a tanker ship for drilling, production, and initial processing. The document outlines the components, schedule, and operations for the proposed TOPS system.
Course Description
This concise course is well balanced and based on more than 30 years of true project experience in Shallow and Deep Water fields around the world, from concept evaluation to first production. It is designed for Project Managers, Project Engineers, experienced or new to Subsea & highly suitable for Cost, Planning, Offshore Installation and Offshore Operation Engineers.
All the Lectures (up-dated on a regular basis) are presented with text, figures and DVDs with videos and detailed animations, used to illustrate many key points of Subsea Technologies. The objective of the course is to equip Engineers and Technicians with a good understanding on the Engineering of Subsea Production Systems (SPS) together with Umbilicals, Risers and Flowlines (SURF) required to link and operate it from

EVOLUTION OF STRUCTURE OF SOME BINARY GROUP-BASED N-BIT COMPARATOR, N-TO-2N D...VIT-AP University
Reversible logic has attracted substantial interest due to its low power consumption which is the main concern of low power VLSI circuit design. In this paper, a novel 4x4 reversible gate called inventive gate has been introduced and using this gate 1-bit, 2-bit, 8-bit, 32-bit and n-bit group-based reversible comparator have been constructed with low value of reversible parameters. The MOS transistor realizations of 1-bit, 2- bit, and 8-bit of reversible comparator are also presented and finding power, delay and power delay product (PDP) with appropriate aspect ratio W/L. Novel inventive gate has the ability to use as an n-to-2n decoder. Different proposed novel reversible circuit design style is compared with the existing ones. The relative results shows that the novel reversible gate wide utility, group-based reversible comparator outperforms the present design style in terms of number of gates, garbage outputs and constant input.

Elucidating Digital deception: Spot counterfeit fragmentVIT-AP University
An ordinary person always has confidence in the integrity of visual imagery and believes it without any doubt. But today's digital technology has eroded this trust. A relatively new method called image forgery is extensively being used everywhere. This paper proposes a method to depict forged regions in the digital image. The results for the proposed work are obtained using the MATLAB version 7.10.0.499(R2010a). The projected design is such that it extracts the regions that are forged. The proposed scheme is composed for uncompressed still images. Experimental outcome reveals well the validity of the proposed approach.
Nippon Dragon Resources Inc. Hard rock revolution has arrived!Nick Vukovich
Nippon Dragon Resources Inc. Hard rock revolution has arrived! Nippon Dragon Resources Inc. is without a doubt one of the most innovative junior mining companies operating today. The Company’s patented “thermal fragmentation” process is ideal for high grade precious/base metal vein deposits. The exploitation of high-grade precious/base metal veins with its exclusive thermal fragmentation process coupled with conventional mining methods will lead the Company in becoming a mid-size gold producer.
Nippon Dragon’s growth strategy is to focus on the development of quality assets that will significantly enhance shareholder value. The acquisition, development and future exploration activities at the Rocmec 1 (Abitibi, Qc, Canada) property is an excellent example of this strategy.
