Development of a computational system to design a helical spring

AbstractSprings are the most basic mechanical elements used in transmission mechanisms. The rapid development of the computer and cellular industry has encouraged spring manufacturers to develop the industry to produce very small springs. Most computer-aided design programs for mechanical parts provide the possibility of designing these parts, as these programs include different types of decisions. All these decisions require coordinates for geometric data as well as metadata. The paper aims to develop software programs to design and analyze springs as one of the most significant mechanical elements used. This paper aims to develop a design software of a helical spring system, where this software is built using a computer program in the language of Visual Basic Version 5. When the user enters data into the system, the system will perform a series of complex calculations in the system, then provide a detailed report on all the engineering dimensions of the spring, and test its efficiency. The output of the software shows the required spring wire parameters. The software was tested with test data from the open literature, and the required wire spring parameters were obtained.

Pair production contribution effect on the calculation of gamma ray dose buildup factor for water and graphite in the energy range (4–10) MeV

Gamma ray buildup factor for two shielding materials, water (Zeff = 7.42) and graphite (Z = 6) for isotropic plane source normally incident within the energy range 4–10 MeV and up to 5 thickness mean free path has been studied. This research has been achieved by writing a simulation computer program in (Visual Basic language version G) and applied depending on Monte Carlo simulation method. The contribution of annihilation effect on the calculation of gamma ray dose buildup factor has been studied for both graphite and water. The results indicated that the calculated values of dose buildup for plane source, when ignoring the contribution of pair production, is less in comparison with the case when the contribution of pair production is taken into consideration. However, the contribution of Compton effect is still more predominant than the effect of annihilation within the range of energy (4–10) MeV.

Pollution assessment of Euphrates River in three governances of Iraq

This study was concerned with assessment the water quality of Euphrates River in the middle of Iraq. Water quality assessment is the overall process of evaluation of the physical, chemical and biological nature of the water. Water pollution for Euphrates River in Middle of Iraq (Babylon, Al-Najaf, and Al-Diwaniya governorates) occurs in both rural and urban areas. In rural areas, drinking water from natural sources such as rivers and streams is usually polluted by organic substances from upstream users who use water for agricultural activities. To protect the water resources from pollution and deterioration which caused by natural pollutants or human activities, an environmental database was constructed and applied. A Visual Basic (version 6.0) Software program was constructed to evaluate the pollutant concentrations using regression models obtained by Data Fit Software program (version 8.0) to make the monitoring system. The result of the program is verified with data of year 2008 which is not included in regression model. This verification shows a good agreement with coefficient of determination ranged between “0.914 to 0.994”To assess water body for compliance with standards that have been set to define requirements for various functions and uses, the water body concerned, were compared with the Iraqi, and WHO standards for domestic and irrigation purposes, for determining whether water quality at sampling sites exceeds water quality standards. A comparison shows that these parameters in some stations are within the Iraqi and WHO standards (i.e. total dissolved solids (TDS): in Al-Musaib, Al-Kufa, Al-Shamya station), and (calcium (Ca): in Al-Hindya Barrage station).

Design Models for Anaerobic Batch Digesters Producing Biogas from Municipal Solid Waste

Models for the design of anaerobic batch digesters producing biogas from municipal solid waste (MSW) in Port Harcourt metropolis, Nigeria have been formulated. Experimental and field data were used to determine relevant design parameters for the batch digesters, especially the bio-kinetic behavior of MSW. The research data were analyzed using material balance analysis. The anaerobic digester was then designed and simulated for fractional conversion values of 0.2 ≤ α ≤ 0.8 and percentage total solids (PTS) concentration of 10-30%, using Microsoft Visual Basic Version 6.0 computer program. The simulation results were interpreted with Microsoft Chart Editor. The evaluation of research results showed that an empirical optimum PTS concentration of 20% was best suited for the batch digester processing the MSW for biogas generation. At this level of PTS concentration, the MSW digestion was most effective in terms of digester sizing, time of digestion, volume of biogas produced and overall cost of the digester, for the same level of percent stabilization.

Modelling Continuous Anaerobic Digestion of Municipal Solid Waste in Biogas Production

In this study, mathematical models were developed for the anaerobic biodegradation of municipal solid waste (MSW) in Port Harcourt metropolis, Nigeria, in a continuously stirred tank bioreactor. The MSW in Port Harcourt is presently not treated before final disposal. The need to incorporate a treatment element into the management scheme has elicited various treatment proposals, including the anaerobic digestion of the waste in a continuous processing system, in order to generate biogas in the process. Bench-scale experimentation was conducted to investigate the behavior of the waste when subjected to anaerobic decomposition in a continuous reactor, leading to the formulation of process models. The development of the models was based on a material balance analysis of the continuous anaerobic biodegradation processes. The models were simulated over a range of fractional conversion (α) of 0.2-0.8 and percentage Total Solids (TS) concentration of 4-10 using the Microsoft Visual Basic Version 6.0 computer programming language. The results of the simulation were further analyzed with the Microsoft Chart Editor, which was used to establish relationships between the various process parameters, including the fractional conversion, time of digestion, effluent substrates and microbial concentrations, volume of gas produced and effluent substrates stabilization. It was found that, whereas the effect of 'α' on the time of digestion is a logarithmic function of the 'α', it is linear for the effluent substrate and microbial concentrations and a power function for the total volume of biogas produced.

Analyses of Anaerobic Batch Digestion of Municipal Solid Waste in the Production of Biogas Using Mathematical Models

The process dynamics of anaerobic digestion of municipal solid waste (MSW) in a batch bioreactor for the production of biogas has been analysed. An anaerobic batch digester was designed for the treatment of MSW in Port Harcourt metropolis, Nigeria, while at the same time generate biogas as a useful by-product. In the course of the design, the biochemical behaviour of the MSW in batch processing was investigated and analysed. Mathematical models were developed to describe the behaviour of the waste using material balance analysis. The models were validated by the formulation of a Microsoft Visual Basic Version 6.0 programme to simulate the digestion process for a fractional conversion of 0.2-0.8 and Total solids (TS) concentration of 4-30%. The results were analysed using Microsoft Chart Editor and showed that the fractional conversion has various levels of effect on other process parameters like the mean cell residence time, substrate and microbial concentrations and the volume of biogas/methane produced.

Using Database Management System to Generate, Manage and Secure Personal Identification Numbers (PIN)

A number of problems are associated with the generation, management and security of PINs, a subset of password. The PINs may be recharge card used by GSM operators or for authentication in ATM. The problems associated with the use of these PINs range from scratching off any of the recharge PIN numbers in recharge card to loss of PIN number or entering invalid number in the case of authentication. It usually takes time for the customer service of the service provider or system administrator to provide convincing solution to these problems promptly when it occurred. PINs generation could seem like simply arranging ranges of number and feeding it into the telecommunication systems such as mobile handsets or ATM to grant access but it requires a specialized and secured way to generate, store and manage it in order to achieve prompt access. This paper focused on the development of database concept to provide solution to these problems by desiging a system by which the PINs generated can be effectively stored and managed so that userss can have immediate access to the PINs if they can provide the identification number on the card. Succintly, the paper discusses the design of a system that generates, manages and secures PINs application using Visual Basic Version 6.0 for designing the front and interface and Microsoft Access 2007 as the database. The system was implemented using real data and the result was successful.

Periodic Yarn Variations that Create Design Effects on Fabric-Development of Related Software Programs

Different periodic faults in yarns create different designs on fabric depending on the wavelength. In this paper, attempts have been made to develop a software program in Microsoft Visual Basic (version 6) to obtain some special effects or designs on fabrics by varying the wavelength of periodic faults. Definite periodic faults are not possible right at this moment, so the faults have been imitated with color effects. Diamond, twill, striped, three dimensional effect, etc. designs can be produced by using this program. Some mathematical functions have been obtained from the software program to create diamond or striped effects on fabrics. Diamond like shapes obtained from the software program have been practically verified on single jersey plain weft-knitted cotton fabrics on a flat-bed machine and found true to a certain extent. Distortions are observed in the design at higher fabric widths due to the uneven tie-dyeing of the fabric by the capillary action of the dye solution used. An attempt has also been made to develop another software program to specify the necessary sequence of colors for a specific length along the continuous weft yarn in a repeat for producing particular design effects or figures on fabrics.

Estimation of rice growth and nitrogen nutrition status using color digital camera image analysis

Non-destructive characterization of crop canopy is important to acquire timely and inexpensive information for crop management and yield prediction. The objective of the present study was to construct a non-destructive method for monitoring crop growth and nitrogen (N) nutrition status with digital camera image analysis. Digital images of rice canopies grown with four cultivars under various nitrogen treatments were captured by a digital camera periodically before heading stage and at the same time rice plants were sampled to measure LAI, shoot dry weight, and shoot N accumulation in 2006, 2007, and 2009. Canopy cover (CC) and ten color indices were calculated from digital camera images using image analysis program developed in Visual Basic version 6.0. More than eight color indices and CC showed significant correlations with growth and N nutrition parameters like LAI, shoot dry weight, and shoot N accumulation. CC revealed the highest correlations with all of them. CC expressed a curve-linear relationship with LAI, shoot dry weight, and shoot N accumulation (X‘s), being well fitted to a negative exponential function: CC=CCmax {1−EXP (−k X)} with asymptote (CCmax) of unity. However, the nonlinear relationship of CC with LAI and shoot N accumulation except shoot dry weight was statistically different among rice cultivars. The statistically different relationships of CC with all the three parameters were found among N fertilization levels as k values increase with the increase of N fertilization level. To compensate the effects of rice cultivar and N level, stepwise multiple linear regression (SMLR) models including nonlinear relationship of CC and color indices were calibrated and validated. The selected SMLR models for LAI, shoot dry weight, and shoot N accumulation showed better performance than the models using only CC as a predictor variable. The selected SMLR models for LAI, shoot dry weight, and shoot N accumulation showed acceptable precision and its accuracy, indicating that conventional color digital camera could be employed for characterizing the growth and N nutrition status of rice non-destructively.

An inverse calculation technique for optimization of gamma ray shielding designs

A new computer code named as SHIELD DESIGN has been developed in Visual Basic Version 6.0 for precise estimation of shielding thickness in gamma ray shielding designs. In the conventional forward calculations using point kernel method, the sources and geometry are specified along with the shield thickness to obtain dose rates at desired locations. But in this code, a new computational technique based on inverse calculation and iterative procedures have been employed to estimate the shield thickness using the dose rate criteria as input information. This new technique enables quicker and easier way of shield design optimization by computing shield thickness required in a single run whereas in the forward shield design optimization method, dose rate computations need to be carried out for various shield thicknesses. The shielding thickness arrived with this code provides a first hand information to the designer to carry out forward calculations for accurate optimization. Also, the code is very useful to regulators for quicker verification of shield calculations submitted by the designers for approval. Further, various options available in this code extend its flexibility and user friendliness. This paper briefly presents the development and validation of the code, SHIELD DESIGN. The validation has been carried out by performing analyses of the gamma shielding design for some standard problems. The results were compared with those of renowned forward calculations, experimental measurements, NCRP-51 benchmarks and other gamma radiation shielding utilities like RAD-PRO and satisfactory agreement was observed. These validation tests demonstrate the precise estimation of shield thickness.

Development of interactive software for evaluations of effective thermal properties in fuel bundles and fuel tubes in Spent Fuel Dry Storage Systems

Recently, insufficient storage room for used fuel at nuclear plants has become a big problem. To solve this problem, many nuclear plants have started to install Spent Fuel Dry Storage Systems. Taiwan Institute of Nuclear Energy Research has started to use the CFD-FLUENT system to analyze and simulate the heat transfer phenomena of Spent Fuel Dry Storage Systems. CFD-FLUENT has a strong calculating function, but on the other hand, it also has disadvantages. For instance, we need to plug thermal properties of materials into a database before we use CFD-FLUENT. However, this CFD-FLUENT data bank is not convenient to build up for the necessary thermal properties of the Spent Fuel Dry Storage System. In addition, those limitations will make the simulating process complicated. The main purpose of this project is to write software which can make the process of plugging properties into the CFD-FLUENT database easier by the use of Visual Basic (version 6.0). In other words, this study is trying to build up a user friendly window operation interface program to enhance the transfer functions and integrate the data in a format that CFD can read easily. Using this user friendly program, the error was less than 10%.

A Modeling Approach towards Improving Compliance of Treated Water Quality to Reduce Manpower and Chemicals

In water treatment processes, the individual unit operations are complex, non-linear and poorly understood. Whilst many models have been developed to improve process understanding, these are rarely in a form easily exploited by the control engineer. Attempts to improve the performance of water treatment works through the application of improved control and measurement have had variable success. This paper discusses investigations into the application of feed forward control on the clarification process of a small-scale pilot plant. The application aimed towards maximizing the efficiency of the chemical coagulation process. To achieve this, a simple computer program written in Visual Basic version 6 models to a chief the process operating conditions. Mathematical models based on historical plant data covering 18 months analyzed by stepwise multiple regression analysis. The following parameters were important determinants of coagulant dose and pH control reagents: river turbidity, pH, temperature, total dissolved solids, and plant flowrate. A predictive equation developed from the data, of the form: Al2(SO4)3 (mg/L) = a*Q + b*Turb + c*TDS + d*pH + e*Temp + f. The aim of this model is to provide water treatment operators with a tool that enables prediction of chemical reagents and treatment conditions for selected removal of turbidity, based on raw water quality data. While for adjusting pH, whether lime or soda ash are added, the pretreatment of water supplies involves the use to decrease the acidity, to soften, and to clear drinking water, calcium oxide (CaO), commonly known as quicklime or burnt lime. The addition of lime is with the form: CaO (mg/L) = j + k *pH. And for soda ash sodium percarbonateNa2CO3 the addition form is: Na2CO3 (mg/L) = m + n*pH. The advantages of software program are significant in the operation of water treatment plant. The program designed as an aid, so the user can still customize and optimize the computer suggested design. Users are able to move forward in adjusting or optimizing the design in minutes, which is difficult for manual system. This system was an initial system, many new features and functions have to be added to the program to enhance the functions and make it commercially robust. It concluded that this system is very powerful tool in improving compliance of treated water quality to reduce labor and chemicals and to facilitate the organizations and individuals with better understanding on how their actions can have a direct impact on the treatment.
