Abstract - The present article describes two different types of technology used in hot water preparation, their advantages and disadvantages, spatial requirements and measuring technology. The facts described herein may be used when deciding on which technology should be used for which type of hot water supply and central heating.
Abstract— Wastewater from dairy industries generally has oils and greases in high concentration and contains high concentration of biochemical oxygen demand (BOD) and chemical oxygen demand (COD). This experimental study is being initiated to evaluate an Activated Sludge Process (ASP) with mixed bacteria for dairy waste water treatment. A three phase study was carried out by varying hydraulic retention time (HRT). The study is being undertaken in two steps in which the bacteria is being cultured in a medium by the process of acclimatization. The later stage will be the determination of the operating parameters. The characteristics of dairy industry waste water were studied and the performance was analyzed. A lab-scale ASP was set up for the study of the performance in treatment of effluent. The effect of various aeration time phases were analyzed in the lab scale Aeration Process for the HRT time of (2, 4, 6) hrs respectively. ASP efficiently removes BOD, COD and nutrients when designed and professionally operated according to local requirements. From the effects of various HRT, the 6 hrs HRT was more efficient in removal of the organic matter. The removal efficiency of COD, BOD and TSS were 97%, 97.5% and 96% respectively. In this process all the parameters were within the standard discharge limits. Hence, the enhancement of organic removal from dairy effluent using ASP was found feasible
Abstract—Augmented reality that is Wearable technology is fast becoming a part of our technological life. There are many devices, from dresses to headphones that can record your day-to- day life. The maturing field of wearable computing aims to inter- weave computing devices into everyday life. This report focuses on smart glasses, one of the categories of wearable computing devices which is present in the media. This paper provides a concise overview of the history and context of Glass based on AR technology. The intended purpose of smart Glass products would be the hands-free displaying of information currently available to most smartphone users, and allowing for interaction with the Internet via natural language voice commands.
Statistical Analysis Approach to Reduce Inter Channel Interference by using Kalaman Filter in term of BER & SNR
Abstract— Many wireless networks have adapted the same communication approach. The OFDM communication is very much inspired from the channel frequencies over the network. In such a network some kind of orthogonal distortion occurs over the channel called Inter Carrier Interference. In this work, we are presenting the concept of mathematical model called Kalman filter to analyze the signal interference and to resolve the problem. In first phase the signal is analyzed for the disruption using Kalman filter and adaptive filter is implemented to reduce the ICI over the signal. The mathematical analysis is performed by using Extended Kalman filter. The result analysis has been performed with respect to BER and the SNR. A novel spatial Kalman filtering scheme is proposed as the second stage to successively cancel the ICI. Simulation results show the effectiveness of the proposed two-stage method and its robustness to channel estimation uncertainties that may arise in practical systems.
