Harry-Ngei harry.ngei09@gmail.com A. A. Ujile harry.ngei09@gmail.com P. N. Ede harry.ngei09@gmail.com <p>This work was predicated on the design and costing of a packed column absorber required to remove SO<sub>2</sub> from an air/SO<sub>2</sub> mixture. The absorber is intended to be developed into an already existing combustion system as a retrofit. The gas flow rate basis of the computation was 40,000Kg/h. The Onda Method was used to estimate the column height as 9m and the column diameter as 2.5m while the column wall thickness as well as the domed head thickness was found to be 9mm using the BS 5500 Standard Method. In order to limit expenses, H<sub>2</sub>O was utilized as the absorber solvent and a flow rate of 29.5Kg/s to limit solvent usage. A pressure drop of 20mmH<sub>2</sub>O/m was assumed in the design with metal pall rings of diameter 51mm and surface area of 102m<sup>2</sup>/m<sup>3</sup> chosen as the packing material. The study estimated a profound $306,559.87 as the cost of the absorber required to remove 95% SO<sub>2</sub> content from the combustion waste stream.&nbsp;</p> 2019-12-01T00:00:00-05:00 Copyright (c) 2019 N.

Harry-Ngei harry.ngei09@gmail.com I. Ubong harry.ngei09@gmail.com E. Ojong harry.ngei09@gmail.com <p>This work highlighted the prediction of the emission rates of the products of combustion using a fuel oil of specific gravity of 0.9. The two reaction pathways of complete combustion and incomplete combustion were used differently to ascertain the emission rates. Ultimate analysis were conducted on the fuel oil to show the percentage composition of elements using ASTM 3178 method for carbon and hydrogen, Kjedahl method for nitrogen, ASTM D1552 for sulphur and the differences used to compute that of oxygen. The estimated percentages of the various elements were the stoichiometrically used to compute the emissions rates at standard conditions. The basis of the computation was a fuel oil flow rate of 10Tonnes/h and the following emission rates were predicted for the complete combustion reaction pathway: 31,246Kg/h for CO<sub>2</sub>, 65Kg/h for H<sub>2</sub>O, 158Kg/h for NO<sub>2</sub> and 20Kg/h for SO<sub>2</sub> while 9,940Kg/h for CO<sub>2</sub>, 15,623Kg/h for CO, 11,700Kg/h for H<sub>2</sub>O, 11Kg/h for H<sub>2</sub>S and 158Kg/h for NO<sub>2</sub> were predicted for the incomplete combustion pathway. The study noted that this predictive path should be taken where effective devices or logistics are not in place to measure emissions from combustion systems.</p> 2019-12-01T00:00:00-05:00 Copyright (c) 2019 N.

Programmers usually adopt code reusability task from previous few years, so that time consumption can be reduces. Code reusability can be done via replication or by just copy-paste. Code reusability leads to not writing code from scratch, just copy paste the useful part of the code. In finding of duplicated code fragment or text, plagiarism detection also work pretty well but it is not applicable to the large system in finding functional clone and also it is more time consuming even at small scale which make the detection method inappropriate. In this paper, we proposed a pattern similarity conditions on the basis of textual similarity for finding the code or text clones in the large content on the basis of SVM, Neural Network using Java coding, Neural Network and Sim Cad. This approach detects code or text clones from original one. The resultant simulation is taken place in the MATLAB environment, and it has shown that it is providing better results. The proposed algorithm performance is measured using parameters i.e. FRR, FAR and Accuracy.</p> 2019-12-03T04:37:24-05:00 Copyright (c) 2019 Pallavi Sharma, Chetanpal Singh https://ejers.org/index.php/ejers/article/view/1641 A Review on Parameters Affecting the Choice of Alternative (Non-Chemical) Weed Control Methods 2019-12-04T01:21:38-05:00 Hasan Sahin hsahin@harran.edu.tr <p>Chemical using as a weed control method is the most preferred method in weed control because they are easily accessible, easily applicable and inexpensive. But, with the new environment-friendly regulations, the importance of non-chemical methods has increased all over the world. In addition, organic farm and non-chemical agricultural methods are gaining importance with increasing social environment and health awareness. Non-chemical methods, called, "alternative methods” have been one of the most popular research subjects in recent years. The physical removal or killing of weeds is usually done by hand or by means designed tools for this task, which varies from country to country. The most known modern non-chemical weed control methods are; electric current,&nbsp; microwave heating, superheated steam, infrared using, pneumatic system, freeze-drying, laser cutting, and fresnel lens systems. The most popular of these methods are; electric current method and microwave heating. In electric current and microwave heating methods, there are no chemical residues in soil and plants after application. It has been shown in the studies that, the microwave weed control method can destroy weeds and seeds when appropriate frequency, sufficient time and required power level are selected. Therefore, in the selection of non-chemical weed control methods, some important parameters of plant and soil should be known. The electrical and dielectric properties of plants and soil such as, electrical resistance (R), impedance (Z), dielectric constant (ε’), loss factor (ε’’), the permittivity (permeability (&nbsp;and conductivity (σ) should be known especially in microwave and electric current methods. The other parameters like the age, height and density of the plant is an issue to be considered in all control methods. But, the moisture content of soil and plant may not be taken into consideration in hot water and steam applications. For the freeze-drying method, the moisture and water content of the plant and soil must also be taken into account.</p> 2019-12-04T01:21:38-05:00 Copyright (c) 2019 Hasan Sahin https://ejers.org/index.php/ejers/article/view/1654 Adaptive and Robust Second Order Sliding Mode Controller Dedicated to Nonlinear Uncertain Pendulum Application System 2019-12-05T05:45:33-05:00 Hedi Dhouibi hedi.dhouibi@laposte.net Jalel Ghabi ghabijalel1975@gmail.com Tarek Selmi tarekissatk@gmail.com <p>The research work presented within this paper deals with an innovative second-order sliding mode control (SOSMC) allocated to adaptive gain and associated with nonlinear systems subject to unknown but bounded uncertainties. The derived controller &nbsp;&nbsp;guarantees the control gain dynamical adaptation for the sake of counteracting the system’s uncertainties and to mitigate the chattering phenomenon. The Lyapunov method is also used to analyses the stability of any closed loop system (CLS) within a finite-time under bounded uncertainties assumptions. To assess how effective is the approach considered within this paper, the adaptive controller has been carefully studied on a benchmark of nonlinear systems on a damped overturned pendulum.</p> 2019-12-05T05:45:33-05:00 Copyright (c) 2019 Hedi Dhouibi, Jalel Ghabi, Tarek Selmi https://ejers.org/index.php/ejers/article/view/1625 Opus and Session Initiation Protocol Security in Voice over IP (VOIP ) 2019-12-05T06:06:10-05:00 Siddarth Kaul kaulsiddarth2013@gmail.com Anuj Jain a1978jain@gmail.com <p>The purpose of the paper is to clearly elaborate how Opus Codec can be used as Voice over IP or Unified Communication as known Opus is an Audio Codec which is royalty free and most versatile format of Audio Codec the Opus codec is used for Interactive Voice and Multimedia application, Opus codec with WEBRTC (Web Real Time Communication) is a framework based on the Chrome Web Browser the codec behavior is usually effectively utilized under testing conditions for understanding the MOS assessment in comparison to the Opus Codec.The Opus codec is generally a low latency codec used for real time interactive communication the Opus codec replaces both Vorbis and Speex for new applications.</p> 2019-12-05T06:06:10-05:00 Copyright (c) 2019 Siddarth Kaul; Anuj Jain https://ejers.org/index.php/ejers/article/view/1628 Vibration Response of Tubular Joints Using a Simplified Mass-Spring Model 2019-12-06T03:43:38-05:00 Shaalan A. Alqarni hamoor07@hotmail.com Khalid H. Almitani salqarni0266@stu.kau.edu.sa Ramzi Othman salqarni0266@stu.kau.edu.sa <p>Using adhesives for joining tubular structures has been widely used to replace the traditional joining methods of welding, brazing, soldering, etc. The unique features associated with adhesives include low manufacturing cost, long components’ life, and lightweight. The goal of this study is to investigate the vibration response of the tubular joints when they are subjected to a harmonic axial load considering that the shear stress is linear through the thickness. A simplified mass-spring model is applied to study the response of the problem analytically. Finite element method (FEM) using ANSYS is then availed to validate and compare results obtained in the analytical approach. Additionally, some parameters such as overlap length and adherent material will be changed to examine their influence on the frequency response. Results and findings achieved analytically and numerically showed that the natural frequencies increase as the adherent wave velocity increases, whereas they decrease as the overlap length increases.</p> 2019-12-06T03:43:38-05:00 Copyright (c) 2019 Shaalan A.

Habibur Rahaman mhrahaman@mun.ca Tariq Iqbal tariq@mun.ca <p>Almost all single-family detached houses in Canada consume enormous electrical energy for space heating and domestic hot water (DHW) purposes. There are many possibilities to design an energy-efficient house. A solar water heating system can be used for domestic water and space heating. Water temperature can be kept constant always by connecting a heat pump or oil burner to the main tank because solar energy is intermittent. The sizing of solar photovoltaic and collector, tank, heat pump are essential to design an effective system based on the system energy consumption. The existing house is just a conventional house where space and water heating are provided by the grid electricity only. In this research, two possible ways of thermal energy storage systems have been designed for a residential single-family house with solar collector and solar photovoltaic. It is proved that the proposed PV based energy storage system is highly suitable considering lower cost, high output power, flexibility, and easy installation.</p> 2019-12-06T06:43:45-05:00 Copyright (c) 2019 Md.
