Importance of an online DSS in inventory management for cement Industry is growing as almost one percentage of sales is lost due to the damage of the cement either in warehouses as is the case of an apex cement company in South India whose net profit is nearly 10 percent of sales. Lack of a scientific system for timely decision making poses difficulty due to additional wharfages, storage space and...
Cooperative diversity is one of the emerging areas in modern wireless network, where each user transmits their own data to the base station and also serves as a relay for other user. For the purpose of relay selection and cooperation, protocols are needed to form groups. Grouping is done based upon the instantaneous Signal to Noise Ratio (SNR) of user to base station channel and the corresponding...
A novel method to improve the performance of Low Density Parity Check (LDPC) Codes using Soft Input Decryption is presented in this paper. A channel coding technique that provides performance near to Shannon's limit is LDPC code. To achieve optimum decoding, Sum-product decoding is used for LDPC Codes. The Soft Input Decryption method is based on the combination of cryptography and channel coding...
A method for controlling the generation of ice for Cold Thermal Energy Storage (CTES) is presented in this paper. A load shifting controller is developed to find the optimum trajectory for CTES in a dynamic environment. The variation in ice building efficiency due to the nonlinear relationship between changing ambient air temperature and ice charge level is accommodated by employing dynamic programming...
This Paper describes the implementation of the enterprise mobile solution to manage multiple diseases. This solution is cost effective & efficient to use for patient. From architecture perspective, solution described here uses M-V-C pattern. This solution targets various stake holders involved in to the medical eco-systems like Patient, HCP, and non HCP. Main focus of this paper is to showcase...
Energy crisis is considered to be one of the greatest problems faced by mankind. During the last decade the prices of fossil fuels like oil, coal has risen sharply and there is a continuous depletion of these scarce resources. Hence there is an urgent need to develop and exploit other alternative sources of energy. In this study, biomethanation of vegetable waste with water hyacinth and cow dung was...
One of the most important technologies for electric vehicles is the drive control technology which does not require a position or speed sensor. In a sensorless vector controlled induction machine, the speed must be estimated from the system measurements. Model Reference Adaptive System (MRAS) based techniques are one of the best methods to estimate the rotor speed due to its performances and straight...
Coastal erosion is a major problem facing the coastlines of the world, which needs to be addressed with priority. Coastal properties and roads are threatened by erosion, particularly during the monsoon. Long lasting coastal protection is needed to solve the beach erosion problems. Breakwaters are effective in reducing the cross shore sediment transport and in wave height reduction in its lee. In the...
The present investigation proposes an efficient low power encoding scheme intended for a 5GS/s 5 bit flash analog to digital converter. The designing of a thermometer code to binary code is one of the challenging issues in the design of a high speed low power flash ADC. An encoder circuit in this paper translates the thermometer code into the intermediate gray code to reduce the effects of bubble...
In this paper realization of a digital excitation system for synchronous generator is discussed. Such a real-time task is implemented using Real-Time Application Interface on Linux platform which is an open source effort. In this work a static excitation system is considered which involved the development of additional hardware circuits such as fully-controlled thyristor bridge-rectifier, the associated...
Wireless mesh networks (WMNs) have been attracting significant attention due to their promising technology. The WMN technology is becoming a major avenue for the fourth generation of wireless mobility. The wireless backbone is tightly integrated with the Internet by some selected nodes called as Gateways. Common single gateway architecture is inadequate for clubbing this high speed network with the...
Reuse of domestic greywater (GW) is emerging as an important approach to the management and conservation of water resources, particularly in rural and developing areas where small-scale decentralized treatments are suited. Vertical flow constructed wetlands have been increasingly used as a sustainable technology for the ecological treatment of wastewater. In this paper, an attempt has been made to...
The present study deals with the suitability of the coagulation-flocculation process using Moringa oleifera seed as an environment-friendly natural coagulant and antimicrobial agent for clarification of turbid water. It has higher efficiency up to 99.99% for higher turbid water. But for low turbid water the removal efficiency is comparatively less. Almost all the industrial effluents are of high turbidity...
In the face of increased awareness of the human impact on the global changes, such as the frequent occurrence of natural disasters, has led the professionals to seek new methods of designing structures that not only can fulfill the desired requirements but also are sustainable in the long term. This paper presents and discusses the adoption of sustainable design in offshore industry, most particularly...
Reducing the greenhouse gas emissions is the need of the hour. Five to eight percent of the world's man-made greenhouse gas emissions are from the Cement industry itself. It is an established fact that the green house gas emissions are reduced by 80% in Geopolymer concrete vis-a-vis the conventional Portland cement manufacturing, as it does not involve carbonate burns etc. Thus Geopolymer based Concrete...
This paper presents a review and performance comparison on several vector quantization (VQ) codebook generation algorithms. The codebook generation algorithms discussed include K-means algorithm, Multi stage vector quantization (MSVQ) algorithm and Predictive split vector quantization (PSVQ)algorithm. The vectors under consideration are the Line Spectral Frequency (LSF) vectors obtained by transforming...
Arcing faults in transmission networks are caused when a current carrying conductor makes an unwanted electrical contact with ground or is temporarily short circuited with another current carrying conductor through a high impedance medium. High impedance arcing faults restricts the flow of current below the detection level of the protective devices and hence cannot be detected by conventional relays...
