No full textThe complexity is increasing day by day with the advancement of buses in interconnected power system. The complexity of the power system can easily handle by analyzing the performance of the transmission system by using load flow study. The real and reactive power losses are largely affected at the transmission level. This paper presents case study of real time system operation to reduce losses and improve the voltage profile with optimum utilization of existing transmission system elements. West-North part of Rajasthan power system having one 400 kV GSS, five 220 kV GSS and nineteen 132 kV GSS have been selected to carry out case study and simulated in PSSE software. Simulation model consists of 55 buses, 34 transmission lines, 66 transformers and 34 capacitor banks. Eight cases have been simulated considering the effect of transformer tap position, closing of opened transmission lines and shunt capacitors. From simulation studies it is found out that transmission losses are reduced by 50.36 % in addition to improve network voltage profile

Role of Different Salts in Dyeing Process and their Replacement
No full textThe present paper was aimed at studying possibility of using different organic salts as substitute of nondegradable inorganic salt in dyeing process as these inorganic electrolytes cause environment problems. Using cationic hydrolyzed starch derived from 2-hydroxypropyltrimethylammonium chloride resulted in enhanced rate of dye fixation with increased DS value for counteracting static repulsion between fibers and reactive dye. Exhaustion and fixation efficiency reported was 30g/L for reactive dyes when sodium edate was used as inorganic salt alternative while sodium citrate gave higher exhaustion and fixation efficiency of 25g/L for same dyes when compared. Use of PEO45 di-block copolymer derived from [2-(methacryloyloxy) ethyl]trimethylammonium chloride(MeDMA) has proved to provide strong attraction to anionic reactive dye increasing dye uptake to 5g/L which is optimum concentration for neutralizing fabrics. While polycarboxylic acid salts has shown same effects regarding exhaustion and fixation as that of sodium sulphate and sodium chloride evaluated by comparing K/S values.

Integration of Quantum Cryptography with Li-Fi
No full textInformation security is one of the vital issues in modern communication networks. There are many mathematics based Security Methods. Quantum Cryptography is a new physics based Cryptographic methods that use nil amount of mathematics for encrypting and decrypting data that means faster access. This method converts and then transferred bits in the form of protons and electrons. Thus, the keys generated can’t be hacked by any computational logics. Meanwhile, Li-Fi, a new network connecting medium that also work with visible light to do communication. Data in Li-Fi is being transferred via visible light from LED’s in the form of electrons and protons as a moderate to supply networked, mobile, top speed transmission in a simple way. If any hacker tries to steal data via eavesdropping or anything else the protons changes its form. This lead to, result in wrong checksum value so the error find by receiving end easily in decoding the data. These both technologies are faster than traditional methods because they use less mathematical computation. So, this research is to integrate Quantum Cryptography with Li-Fi via methods of physics, which is light to make network and communication more secure, robust, reliable and faster
Novel Technique for Virtual ID Generation to Isolate Selective Forward Attack in Opportunistic Network
No full textMobile opportunistic network is a delay tolerant network. They are specially characterized by their intermittent connectivity. End to end connectivity is not available. They use store-carry-forward technique for transmission of data. Opportunistic network has various privacy and security challenges. The aim of the implementing privacy in the opportunistic network is to attract more users to use this network. As the main concern in this network is privacy and, there is not a fixed infrastructure present and the message is forwarded through many intermediate nodes, so, there may be a selfish node which is not interested to forward the message to a particular destination, or the user does not want to show its identity when it wants to communicate or send message to a particular destination, then it is a risk or threat to the privacy of user or the packet is dropped by the selfish node. In this paper we have discussed various attacks which can be triggered in opportunistic networks. Selective Forwarding attack is the main focus of this research. Due to this attack network performance degrades. A novel technique has been proposed based on the basis of virtual ID’s. Network performance is also evaluated on the basis of packet loss, throughput, energy loss, and delay
