Comparative Analysis of Ceramic Product Manufactured from Traditional Raw Materials and Local Raw Materials in Bangladesh
Get PDFCeramic industries in Bangladesh are using raw materials imported from abroad. For this reason, manufacturing costs of the ceramic products are quite high. Now a day, the demand of the ceramic products in Bangladesh is very high. To reduce the cost of these ceramic products, different types of local clays can be used as raw materials with quartz and feldspar to manufacture ceramic ware, tile, and sanitary ware. In this research, locally available clay of nine different areas had been used to prepare the sample. Their physical and mechanical properties were tested and studied to evaluate the quality of the products. Khagrachari (canal) and Padma (north) clay have shown better physical and mechanical properties. This clay is suitable for the production of ceramic ware and Khagrachari (Hill) and Padma (South) clay for quality tiles. The compositions of locally available clays were determined using X-Ray Fluorescence (XRF). XRF analysis showed the presence of excess SiO2 content in the form of Silicate, Fe2O3, and TiO2 but the amount of Al2O3 in most of the compositions was also not up to the minimum level. Observing the physical and mechanical properties, it is found that the local clay materials are suitable to use in ceramic industries by replacing the imported/traditional clay to reduce cost and make a perfect use of our natural resources
An Improved Image Restoration and Edge Detection Technique
Get PDFClustering and edge based segmentation are two basic image segmentation technique. This paper involves image clustering based restoration technique for finding out the set of consequential groups and restoring the original image from a noisy image. Previously, the feature of image cluster computing and restoration method is researched separately but now we combined the cluster and restoration method together. The k means clustering algorithm is applied on similar objects to create a cluster that separate noisy pixels and finally we use Gaussian filter to restore the noise corrupted image which enhanced the image quality. The simulation results show that the techniques are able to produce better output in terms of contrast and resolution. In case of edge based segmentation, canny edge detection algorithm is the optimal one because of its low error rate, good localization, only one response to a single edge etc. In this work, we have showed that applying double threshold in canny edge detection algorithm provides reasonably better output
Review on the Performance of Different Types of Filter in the Presence of Various Noises
Get PDFAn efficient filter must have the quality of removing noise at the same time preserving the information. On the other hand, noise contaminates in the field of signal processing and communication due to various unwanted nonlinear effects. So study of the characteristics of different types of noise is necessary. Also, how various types of filters response to these noises are also important? In this paper, we have studied the characteristics of four types of noise namely Salt & pepper noise, Gaussian noise, Speckle noise and Poisson noise and analyzed the performance of four basic types of filters such as Mean filter, Median filter, Wiener filter and Gaussian filter to suppress the noises mentioned previously
A Way to Unlock The Electricity Energy Market for The Common People Using CP Model
Get PDFThe electricity energy market is almost locked for the people. The trade of electric energy is defined as electricity energy market. In most of the countries, trade of kWh by the people is found very rare practice unlike other businesses. However, business related with energy and power equipment may be accomplished by individual if ones want. On the other hand, selling the kWh is somehow difficult. Few possible reasons that create resistance for a person to enter into electricity energy market such as the large size of power station, higher initial cost and lengthy procedures. This paper discusses the states the power of electricity market and proposes a way to unlock electricity energy market for people using CP (Consumer Producer) model. A way to widen the entry of electricity market may be the minimization of the size of the power station into very small unit which will have lower initial cost, quick as well as easy installation
Commercial Applications of Blockchain and Distributed Ledger Technology
Get PDFBlockchains are distributed ledgers. Distributed ledgers replace centralized ledgers. Distributed ledgers use nodes—computers—to record, share, and synchronize transactions in their electronic ledgers. The paper examines how blockchain data is arranged into blocks and how an append-only mode chain links them. Distributed ledger technology (DLT) encrypts and consensuses immutable and sequential transaction records. Bitcoin pioneered blockchain. Since then, many blockchains with decentralization, encryption, consensus, and immutability have been developed for diverse uses. Blockchain technology is most typically used in transaction settlement, digital currency banks, and supply chain applications to solve problems quickly. The study examines how blockchain and DLTs might improve information management and build new technologies like the Internet of Things. The study shows how legal issues encourage blockchain technology despite limited international and federal restrictions. However, data privacy and security must be addressed immediately
Digitization in Production: A Timely Opportunity
Get PDFUsing modern digital technology, the production team aspires to innovate and enhance existing procedures. However, the majority of the time, information about these new technology exists outside of a company\u27s walls. The idea of absorptive capacity, as well as literature on open innovation, are used by the authors to investigate the function of external search in the digitalization of the manufacturing industry. Companies in the manufacturing industry who want to digitize their processes can profit from inbound open process innovation, but the effectiveness of this approach differs depending on which cluster of digital technologies is being used. In general, the findings imply that enterprises should focus on developing strong links with a small number of external knowledge partners rather than maintaining superficial relationships with a large number. An investigation of the relationship between enterprises\u27 external search and their use of digital technology is presented in this paper, which contributes to the expanding body of literature on the digitalization of manufacturing. It contributes to the literature on open process innovation by providing early empirical insights
Effect of Fluegas Flowrate on Sizing of Venturi Scrubber using Aspen Process Tool-Aspen Venturi
Get PDFDesign of the preheat venturi scrubber has been performed using the process tool ASPEN Venturi by ASPEN Process Tool V 8.0- aspen one. Venturi scrubbers can be design using either the flowrate of gas at inlet conditions or the saturated gas flowrate. Various input parameter introduced in this research to be specified for sizing which included, Liquid to Gas ratio is kept 3.339 Litre/m3, Gas pressure drop is 4.9835 kPa, Entering gas temperature at standard conditions is 371.1°C and Liquid (water) volumetric flowrate is 0.000794 m3/sec. It is observed that higher values of Liquid to Gas ratio gives a higher pressure drop. As most commonly, Liquid and gas enters at converging section, or liquid can also be introduced from throat. As area decreases, gas velocity increases and pressure drop becomes higher which in accordance to Bernoulli\u27s Equation. By keeping all the parameter constant likewise Liquid to Gas ratio and Gas pressure drop for all the process. At gas flowrate 0.2 m3/sec and 1.4 m3/sec, we get Throat Velocity 43.94 m/sec and 106.3 m/sec, Throat Diameter 0.07613 m and 0.13 m and Throat Length 1.6 m and 0.205 m, respectively. From graphical trend, it is proved that Gas flowrate is directly proportional to Throat velocity and diameter and inversely proportional to Throat length
Modeling Damping for a Loaded Spring in an Acoustic Liquid Media
Get PDFFree vibrating motion can take place in an acoustic media. This motion can be steady hence have constant periodic variations or unsteady and thus experience light damping or heavy damping. We give a modeled analysis of unsteady periodic motion of an oscillator in a cylindrical acoustic medium that allow such waves to be transmitted through them. This has been approached by calculating variation within the proposed boundary functions and boundary potentials. Limitations for these calculations have been done depending on the time, and how free oscillations are expected to behave in cylinder carrying a suspended mass. This work investigated motion by constructions that interact with their environment with the acoustic media. Since the dynamics considered here were very complex, modeling the system with one grade of free motion and applying different types of constructions whether ground, underground, cylindrical, spherical constructions and containers was considered. This work borrowed heavily on the modeling of seismic and blast waves as modeled with rigid inclusions containing elastically fastened mass interacting continuous solid medium. This study joined motion of any continuous medium with other discrete systems. The results displayed measurement systems for wave processes having interference at their eigen- frequencies just like those under seismic wave interactions and this work considered the result as similar to those in discrete systems
