Abstract :

Expansive alkali silica gel forms due to the alkali reaction with reactive aggregates.  Cracks and damage to the part of the concrete structure are the results of the formation of this expansive gel. There are several ways to minimize this reaction, out of which Lithium Nitrate compound is believed to reduce the reaction between alkalis (present in the cement) and silica (present in the aggregates). In this paper a laboratory investigation has been done with the combination of reactive aggregate, OPC and varying percentage of Lithium Nitrate to evaluate the effectiveness of Lithium Nitrate compound in controlling expansions resulting from alkali-silica reaction.

Abstract :

By survey we mostly used electric energy in daily life. In domestic purpose hot water are used for various applications. Various coils are used for heating purpose to save electric energy up to literature survey coil design made by various author but in this experiment water properties will change and studied about water properties after treatment. There are various method which are used for to change property of water like in this experiment we concentrate on pH of water. Ph of water changes by natural resources and observe what effect on water heat property by changing property of water. There will be getting best method to reduce electric energy so whenever coil or electric furnace boiler used there will be water treated process will conduct. There is hypothesis is if change in pH of water due to that electricity required to heat water is also vary. In Soudhi Arabian countries they are studied in water property because mostly there are available sea water which pH is large so when use  is water for that that steam generation that time required fuel is large if compare with when pH is less Because impurities added in water.

Abstract :

To reduce the membrane fouling in an immersed membrane bioreactor (MBR) during the treatment of food wastewater, an additional continuous stirring was introduced. The results showed that both a better membrane performance and a higher degradation efficiency for food wastewater were obtained. The membrane contributed mostly in concentrating the activated sludge. The bioreactor ensured the degradation of the organic matter. The resistance caused by concentration polarization decreased under continuous–stirring, and the membrane flux reached 14.68 L/h*m2, which was 3 times the membrane flux under non-stirring condition. The COD removal and the ammonia nitrogen removal reached 93% and 90%, respectively.

Abstract :

In today’s times, the designing of piping systems has become an important field. With increased urbanization, and construction of complex infrastructures like advanced warehouses, factories, power distribution centers, refineries, multi-storied residential and  commercial buildings, etc. , having a good piping system is a must for supplying adequate amount of clean water for fighting against fire threats. Earlier, piping design was done by using many manual calculations and formulation methods. This made piping design a laborious and time-consuming process and it was also prone to large amount of errors. However, modern piping design is done by using software such as ANSYS, CFD, AUTOCAD, etc. for doing calculations and drawing/designing the required layout. This not only reduces the computation times, but also allows us to have a virtual simulation of the chosen design, thereby giving us a better idea about how effective the chosen piping design will be before it is implemented, thus allowing us to fine tune the design for better output and also reducing the errors. In this paper, we highlight the requirements of a good piping system, and we elaborate upon the various steps involved in designing of such systems, and choosing the suitable type of piping layout for the required conditions such as available pressure, consumption demand, flow rate, etc. and performing various calculations on the basis of the above factors.

Abstract :

Deregulation  and privatization of power market worldwide has forced to identify the different ancillary services and the service providers in order to price the services properly. Active and reactive power pricing is an important process that can never be avoided and constitutes a considerable part of economy. An exclusive reactive power management is essential for the secure operation of power systems and reactive power support is considered as an essential system support service for competitive electricity power markets. In this market, Pool- co and bilateral power trading plays a vital role where the amount of power and the flow path between the transacting generators and loads are fixed beforehand. The ability of FACTS devices is to control the power flow through designated routes in transmission lines and thereby reducing the overloading of lines and ensures the more flexible operation. The objective of this paper is to propose various transmission pricing approaches with FACTS devices of Unified Power Flow Controller (UPFC) for determining the locational marginal prices of proposed test system. A case study with Indian 246-NREG bus system is conceded to illustrate the effectiveness of the proposed transmission cost allocation procedures and test results are presented. Finally, the simulation results are compared with/without FACTS devices for Pool-co and bilateral energy markets.

Abstract :

Interactions of concrete with persistentprevailing environmental conditions will alter its material properties and cause deteriorations. Such phenomenon is very common in various elements of dams. Konar dam is an earthen dam with concrete spillway built across the Konar river (23.9411° N, 85.7750° E) in Hazaribag district of Jharkhand, India. It is 3,549 m long and 49 m high dam with 110 m long concrete spillway.The project was commissioned in 1955.  Besides providing irrigation facilities to 45,000 hectares of agricultural land, it supplies clean water to the thermal power plant located at Bokaro. Observation of horizontal cracks of 2-4 mm width extending continuously all along the upstream as well as downstream facesin the galleries from one end to other necessitated evaluation of the quality of concrete with regard to its strength and other associated properties.  For initial broad spectrum diagnosis and overall assessment of the status of concrete,ultrasonic pulse velocity technique was adopted. Based on the test observations,locations for extraction of cores for further investigationswere identified on upstream as well as downstream faces of galleries. This paper presents the outcome of various investigations that were carried out for structural assessment of different grades of concrete used in the dam.

Abstract :

Instrumentation for dams is mainly required for two purposes, to compare the parameters during actual execution of project with the parameters designed and to detect any unusual or abnormal behavior of structure during construction and post -construction so that any future hazards can be predicted. Instrumentation may differ for different kind of dams.  Instrumentation for concrete dams is needed to monitor performance of mainly concrete super structure and foundation. Proper instrumentation plan can evaluate actual behaviour of dam and its pertinent structures. This paper briefly discusses instrumentation of concrete dam along with specific parameters to be monitored, instruments required and frequency of instrumentation for different parameters. A case study of instrumentation is also discussed.

Title : Modeling and Control of Negative output Triple-Lift Luo Converter Using Fuzzy Logic Controller

Abstract :

The voltage lift technique is a popular method widely applied in electronic circuit design. Since the effect of parasitic elements limits the output voltage and power transfer efficiency of DC-DC converters, the voltage lift technique improve circuit characteristics. This technique has been successfully applied for DC-DC converters resulting Luo converters.  Negative output Triple-Lift Luo converters are another series of new DC-DC step-up (boost) converters, which were developed from elementary Luo converter using the voltage lift technique. Triple lift LUO circuit is derived from negative output elementary Luo converter by adding the lift circuit three times. These converters perform positive to negative DC-DC voltage-increasing conversion with high power density, high efficiency and cheap topology in simple structure. Since the power electronic converters become very complex, soft computing techniques are proper choice for controlling these systems. The classical control methods employed to design the controllers for Luo converters depend on the operating point so that it is very difficult to select control parameters because of the presence of parasitic elements, time varying loads and variable supply voltages. Conventional controllers require a good knowledge of the system and accurate tuning in order to obtain the desired performances. A Fuzzy Logic Controller (FLC) which is one of the soft computing technique has been developed for the control of Triple-Lift converter to achieve  good dynamic performances i.e. minimum value of rise time, settling time and peak overshoot in the presence of input voltage variations and load changes and invariant dynamic performance in the presence of varying operating conditions. The proposed technique is evaluated on a Luo converter under different operating conditions by using MATLAB - SIMULINK software. The results are presented and analysed.

Abstract :

Maintenance of power system stability becomes vital during disturbances like faults, contingency etc. This work deals with a novel priority oriented optimal reactive power compensation of Doubly-Fed Induction Generator (DFIG) based wind turbine using Static Synchronous Compensator (STATCOM). A multi-objective problem will be formulated to maintain voltage within its tolerance levels using Voltage Severity Index (VSI) and to mitigate low frequency oscillations by using Transient Power Severity Index (TPSI) during post-fault conditions. An optimal solution to this proposed problem will be obtained using Fuzzy Logic. In order to justify the proposed methodology it is simulated and tested using 2 MW DFIG with MATLAB- Simulink.

Abstract :

Hash Function is a special class of function that has certain properties which make it suitable for use in cryptography. Cryptographic hash functions are widely used in digital signatures, message authentication codes (MAC) and also other forms of authentication. They are widely used insecurity protocols, passwords and pseudorandom number generation. MD5, SHA, RIPEMD and Whirlpool are some of the hash functions already available in real time applications. These algorithms involve more number of operations and iterations and thereby consume more time. In this paper, a new hash function using stack data structure with page replacement principle is proposed. From the experimental, it is observed that the proposed method is simple and easy to implement for less volume of data.

Abstract :

In this study, the effect of various dosages of natural zeolite (NZ) on the mechanical properties of recycled coarse aggregates concrete (RC) was presented. The RC was prepared by using 0, 25, 50 and 100% coarse aggregate replacement and sourced from demolished concrete piles and building projects. Three dosages of NZ i.e. 10, 20 and 30% were replaced with cement.  Mechanical properties as compressive strength, splitting tensile strength, modulus of elasticity and ultrasonic pulse velocity were evaluated. The test results demonstrated that although compared with other NZ dosages, the use of 10% of NZ as a conservative dosage of NZ, lead to more mechanical properties, but a combination of 25% of RA replacement and 20% of NZ replacement can produce RC with mechanical properties close to RC made with 10 of NZ.

Abstract :

Wireless and mobile technology is rapidly gaining in popularity in both home and business networking and has become quickly a promising technology in today’s emerging technologies. The advantages of wireless transmission include mobility and elimination of cables while its disadvantages include the potential for radio interference due to weather, other wireless devices, or physical obtrusions such as walls. A new type of broadband access network known as wireless mesh network (WMN) enhances the potentials of wireless and mobile networks by using the wireless mesh routers and wireless mesh clients. The main characteristic of a WMN is that the nodes at the core of the network are responsible for forwarding data to and fro clients, forming thus the Mobile and Ad- hoc Network (MANET). Unfortunately, the inherent shortcomings of WMNs, such as dynamic topology, the limitations of mobile terminals and heterogeneity makes it’s end to end QOS become very difficult and challenging.  In this work, we propose an MPLS internetworking approach that builds on the capability of traffic engineering in an IP-network by identifying traffic flows by labels and creating explicit routes (label switching paths (LSPs) for various traffic flows to solve these challenges. This approach uses ATM technology to address certain issues of WMNs such as reliable handoff procedure, bandwidth management, distributions of traffics as well as capacity. The theoretical aspects related to this MPLS protocol, its functionality, strengths and weaknesses as well as their implementations were discussed. The unsuitability of WMNs for Traffic Engineering and efficient resource allocation was also discussed.
