Laboratory design of an ozone concentration regulator which is build on the theory of continuity
equation for gas flow in parallel pipes in conjunction with the ozone elimination potentials of an ozone
destructor is presented. At an initial oxygen flow rate of 33.33 cm3s-1, ozone concentration was generated
and varied between 429.30 parts per million (ppm) to 3826.60 ppm. Similarly at an initial oxygen flow rate
of 25 cm3s-1, ozone concentration was generated and varied between 387.30 ppm to 4435.20 ppm. Effect
of flow meter when the ozone concentration was set to approximate 1000 ppm were investigated and
reported. Fine tuning of the regulator is necessary to ensure concentration stability for long duration
experimental work.
In this study the kinematic wave equation has been solved numerically using the modified Lax
explicit finite difference scheme (MLEFDS) and used for flood routing in a wide prismatic channel and a nonprismatic
channel. Two flood waves, one sinusoidal wave and one exponential wave, have been imposed at the
upstream boundary of the channel in which the flow is initially uniform. Six different schemes have been
introduced and used to compute the routing parameter, the wave celerity c. Two of these schemes are based on
constant depth and use constant celerity throughout the computation process. The rest of the schemes are based
on local depths and give celerity dependent on time and space. The effects of the routing parameter c on the
travel time of flood wave, the subsidence of the flood peak and the conservation flood flow volume have been
studied. The results seem to indicate that there is a minimal loss/gain of flow volume whatever the scheme is.
While it is confirmed that neither of the schemes is 100% volume conservative, it is found that the scheme
Kinematic Wave Model-2 (KWM-II) gives the most accurate result giving only 0.1% error in perspective of
volume conservation. The results obtained in this study are in good qualitative agreement with those obtained in
other similar studies.

High-precision Ultrasonic Flowmeter for Mining Applications based on Velocity...TELKOMNIKA JOURNAL
The flowmeter is widely used in coal mining because of its higher measurement
precision and simple installation without channel project modification. In this paper, a flow
measurement method based on velocity-area is investigated, and a functional flowmeter for
mining applications with higher precision is designed. The two key parameters, the liquid level
and flow velocity are required to be obtained for achieving the proposed method. The proposed
flowmeter is composed of three main functional modules: (1) flow velocity detection module
based on ultrasonic time difference method, (2) liquid level detection module, and (3) mud level
detection module based on ultrasonic pulse echo method. All the measured data are transferred
to the monitoring station for analysis and displayed in real-time through M-BUS. The flowmeter
is designed focusing on mining applications, and has higher benefits for preventing water
disasters in coal mines.
Analytical modelling of groundwater wells and well systems: how to get it r...Anton Nikulenkov
Aquifer tests are probably the most widely used methods to obtain hydrogeological properties that are vital for any mine dewatering or environmental impact assessments. Numerous softwares and methods currently exist that provide quick and easy tests interpretation by fitting theoretical and measured drawdown curves. However, misinterpreting a-priory groundwater concepts and not accounting correctly for such factors as skin-effect, well storage or partial penetration may result in hydraulic conductivity errors by several hundred precents. As illustrated by case studies from WA, both numerical and analytical models generally suffer from non-uniqueness that can be overcome by understanding a-priory groundwater concepts and implementing them appropriately into the interpretation algorithms.
The presentation also discusses an analytical approach for well systems design. The methodology is presently incorporated in ANSDIMAT software package that is developed by the Russian Academy of Sciences. The method uses standard and research analytical solutions and it is based on the principle of superposition. Unlike numerical models, the method allows calculating drawdowns inside a pumping well and regional drawdowns, for example, on an open pit contour. A particle tracking component, incorporated into the methodology, provides a practical alternative to numerical models for simplified environmental impact assessments.

Liquid Level Estimation in Dynamic Condition using Kalman FilterIJERA Editor
The aim of this paper is to estimate true liquid level of tank from noisy measurements due to dynamic conditions
using kalman filter algorithm. We proposed kalman filter based approach to reduce noise in liquid level
measurement system due to effect like sloshing. The function of kalman filter is to reduce error in liquid level
measurement that produced from sensor resulting from effect like sloshing in dynamic environment. A prototype
model was constructed and placed in dynamic condition, level data was acquired using ultrasonic sensor to
verify the effectiveness of kalman filter. The tabulated data are shown for comparison of accuracy and error
analysis between both measurements with Kalman filter and statistical averaging filter. After several test with
different liquid levels and analysis of the recorded data, the technique shows the usefulness in liquid level
measurement application in dynamic condition.
Design Analysis and Simulation of 25 TAP FIR Raised Cosine Filter IJEEE
Pulse shaping filter plays an important in multirate signal processing for Software Defined Radio based wireless and mobile applications. In this paper Raised Cosine filter has been presented for pulse shaping using Kaiser and Gaussian window techniques. The raised cosine filter introduces group delay that causes ISI in wireless communication. The ISI due to group delay can be removed by delaying the input signal to the filter. The ISI can also be rejected by reduced roll off factor α which results in narrow transition width. The proposed filter has been designed and simulated using Matlab. The simulated results show that the performance of both window techniques are almost same but Gaussian window based pulse shaping filter provides improved stop band attenuation is better as compared to Kaiser window technique.
This software analyzes an Exfiltration Trench better known as French Drain for various methods, ambient conditions, and storm parameters. The user has the ability to analyze his design and perform flood routing calculations in order to evaluate the capacity of the exfiltration trench. The software will generate the input and output hydrograph, as well as calculating the maximum stage within the French Drain. The boundary conditions such as the water table or the tail water could be constant or variable type series. A French Drain could be analyzed and designed using five different hydrologic methods.

UNDER WATER NOISE REDUCTION USING WAVELET AND SAVITZKY-GOLAYcsandit
A precise, linear indication of the depth of water in a specific part of water body is what always
required. Presently there are a wide variety of ways to produce a signal that tracks the depth of
water.The Ultrasonic signal is most commonly used for the depth estimation. This signal is
affected by various underwater noises which results in inaccurate depth estimation. The
objective of this paper is to provide noise reduction methods for underwater acoustic signal.In
present work, the signal processing is done on the data collected using TC2122 dual frequency
transducer along with the Navisound 415 echo sounder. There are two signal processing
techniques which are used: The first method is denoising algorithm based on Stationary wavelet
transform (SWT)and second method is Savitzky-Golay filter. The results are evaluated based on
the criteria of peak signal to noise ratio and 3D Surfer plots of the dam reservoir whose depth
estimation has to be done.

Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop.

The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

1. DESIGN OF SIGNALIZED INTERSECTION
One of the important steps in designing a fixed time signal
system is to determine the cycle time.
• Main consideration in selecting the cycle time should be
that the least delay is caused to the traffic passing
through the intersection.
• If the cycle time is small, the proportion of the time
lost to the cycle time will be high, resulting in an
inefficient signal operation and lengthy delays.
• If the cycle time is too large, there is a danger that a
good portion of the green time will be used by
unsaturated flow of traffic, which again leads to
inefficiency.
Dr. Rizwan Memon 1
2. The optimum cycle time can be obtained by the following
equation:
seconds
Where Co = optimum cycle time
L = total lost time per cycle (in seconds)
Y = y1 + y2 + ………….. + yn
and y1, y2, … yn are the maximum ratios of flow to saturation
flow for phase 1, 2,….n
(i.e. (q / s) where q is the flow and s is the saturation flow).

3. The above figure shows that as soon as the green signal is given, the rate of
discharge begins to pick up and some time is lost before the flow reaches the
maximum value (saturation flow).
Dr. Rizwan Memon 3
4. Saturation Flow:
In determining the y values the saturation flow should be
measured at existing sites, wherever possible. In absence of
such data the following simple formula devised by the Road
Research Laboratory (RRL), U.K can be used.
s = 525 w (PCU/hour)
where s = saturation flow
w = width of approach road in meters
The above formula is valid for widths of from 5.5 to 18 m. For
lesser widths the values may be obtained from following
table.
Width w in
