Study on Laser Communication: Features, Application, Advantages

Laser communications offer a viable alternative to RF communications for intersatellite links and other applications where high-performance links are necessary. High data rate, small antenna size, narrow beam divergence, and a narrow field of view are characteristics of laser communication that offer a number of potential advantages for system design. The high data rate and large information throughput available with laser communications are many times greater than in radio frequency (RF) systems. 

The small antenna size requires only a small increase in the weight and volume of host vehicle. In addition, this feature substantially reduces blockage of fields of view of the most desirable areas on satellites. The smaller antennas, with diameters typically less than 30cm, create less momentum disturbance to any sensitive satellite sensors. The narrow beam divergence of affords interference-free and secure operation.

MIMO-OFDM's BER and Design Performance for Wireless Broadband Communications

To get high data rates, speed and immediate amplify in range and reliability without consuming more radio frequency require MIMO-OFDM for wireless broadband communication. In this paper, we investigate the performance of MIMO-OFDM using diverse modulation schemes are used to encode and decode the data stream in wireless communication over AWGN channel for the indefinite transmitter and known receiver. In exacting we relate MIMO detection methods based on V-BLAST (Vertical Bells Lab Layered Space Time) planning to develop spectral efficiency.

Strength and Durability of High Strength Fibre Reinforced Self Compacting Concrete with Nano Silica

Conventional concrete used in building and civil engineering applications requires compaction to achieve strength, durability and homogeneity. The typical method of compaction, vibration, generates delays and additional costs in projects and moreover is a health hazard in and around construction sites. Self-Compacting Concrete is a highly flow able, stable concrete which flows readily into place, filling formwork without any consolidation and without undergoing any significant segregation. 

In the present experimental investigation the glass Fibres are added in different proportion (0%,0.5%,0.75%,1%) to total volume of cement and 4% of nano silica is constantly added in all mix of SCC & to study the fresh and harden properties such as workability, compressive, split tensile flexural strength and durability test (sulphate resistance) on M50 grades concrete. 

Finally the test results are compared with conventional concrete. Based on the tests results, the use of 0.75% glass fibre with 4% of nano silica in self compacting concrete improves the quality of concreting & produce comparatively better results in both strength as well as durability aspect.

Design of Dual Pulsating Latch Flip-Flop (DPLFF) using Novel Pulse Generator

In this paper various flip-flop structures have been studied. In all designs to reduce power consumption, the Pulse Generator circuitry should be in build along with the flip-flop itself. If a pulse generator is included along with DPSCRFF structure, power consumption can be reduced. In this work a new design of flip-flop, Double Pulse Latch Flip-flop (DPLFF) is proposed. DPLFF eliminates unnecessary glitches, which consume more power. 

DPLFF consume less power for same delay as compared with other existing techniques, which is performing one of the fastest known flip-flops. In serial operation as shift register the proposed DPLFF can perform better at the higher frequency. The stacking of transistor in the latch stage cause reduction in subthreshold leakage current & thus the static power consumption is also less for DPLFF. This is better suited for low power circuits at deep submicron technology where leakages are more dominant.

Cooling by using Earthen Pot

Demand for electric power is more in summer is concern for most utilities. However evaporating cooling required more amount of water which is main source as an evaporator, and this only work efficiently when humidity is low. Evaporating cooling could be a quite common kind of cooling for the thermal comfort since it is relative low cost and needed less energy than several different styles of cooling. In our project, we are using earthen pots and soft cotton curtains are used for cooled air. Meeting demand for electrical power throughout peak periods in the summer may be a major concern for many utilities within the fast-moving world. 

From the demand points of read on the grid and value to the consumer, need to quite know install, energy-efficient evaporative coolers instead of standard air conditioners.

An Efficient Securing Code Based Cloud Storage using RC5 Encryption Algorithm against Pollution Attacks

The widespread diffusion of distributed and cloud storage solutions has changed dramatically the way users, system designers, and service providers manage their data. Outsourcing data on remote storage provides indeed many advantages in terms of both capital and operational costs. To provide solutions for the above pollution attack and user data breach, we propose an early pollution detection algorithm able to spot the presence of an attack while fetching the data from cloud storage during the normal disk reading operations. 

Thus each fragment is check for malicious content and passed over to the server for processing. 

The alarm triggers a procedure that locates the polluting nodes in early stage of processing to avoid the intrusion. Also to detect the polluted content hashing methods are used. In this way, after network peers receive the transmitted data, hash value is calculated by hash functions and then the result is compared with the received hash value from the content distribution network (CDN) servers to determine whether the transmitted data is polluted or not. 

I proposed system to addresses in preserving user data confidentiality and integrity after outsourcing. For this concern, we present our design for a new cloud storage encryption scheme that enables cloud storage providers to create convincing fake user secrets to protect user privacy.

An Efficient File Hierarchy based E-System with Clinical Document Architecture in Cloud Computing

E- Healthcare system monitors the health condition and gives medical treatment through our web application. They collect the real time personal information (PHI) and patient's physical problem and transmitted it to the healthcare provider. To securely share the PHR information in cloud computing, a patient divides his PHR information M into two parts: personal information m1 that may contain the patient's name, social security number, telephone number, home address, etc. The medical record m2 which does not contain sensitive personal information, such as medical test results, treatment protocols, and operation notes. 

Then the patient adopts CP-ABE scheme to encrypt the information m1 and m2 by different access policies based on the actual need. Also we propose The Clinical Document Architecture (CDA). Our CDA document integration system integrates multiple CDA documents per patient into a single CDA document and physicians and patients can browse the clinical data in chronological order and historical wise.
