Title: Evolutionary algorithm based controller for heat exchanger
Author (s): Nandhini Priyadharshini M., Rakesh Kumar S. and Valarmathi R.
Abstract:

Qualified and resourceful control strategies have recently emerged with an optimized solution while dealing with systems that are non-linear. This paper is endeavor to intend an optimized control strategy which proceeds a scheme of developing pre-dominant PID controller and Fractional order PID controller which is enforced to deal with the non-linear heat exchanger system. The Fractional order PID controller has the non-integer order of integration and differentiation operant that made the controller more robust. For evaluating the performance, the FOPID controller is compared with traditional PID controller. The parameters of both the controllers were optimized by minimizing the objective function using evolutionary algorithms such as Genetic Algorithm (GA) and Particle Swarm Optimization (PSO). An objective function is defined by Integral Time Absolute Error (ITAE). From the entire simulation results it is observed that PSO based FOPID performs well when compared with PID controller.

Title: Vertical profiles of stream wise velocity inside non- and vegetated meandering compound channel
Author (s): Abdul Haslim Abdul Shukor Lim, Zulhilmi Ismail, Mohamad Hidayat Jamal and Mazlin Jumain
Abstract:

Advances in computer capabilities have increased the interest of using more complex simulation model into solving the Navier Stokes equation in open channel. Computational fluid dynamics using Large Eddy Simulation model were used to simulate the vegetation presence on floodplain along main channel inside meandering compound channel. Simulations were done for two different relative depths for non- and vegetated cases. The measured and predicted in bank stream wise velocity were compared at bend apex of the compound channel for validation. Presence of vegetation significantly reduces the velocity in the area near the vegetated main-channel and floodplain interface also in the area protected from the upstream flows. The numerical result shows that the flows inside the main channel were greatly affected by the vegetation especially for low relative depth. Interaction between stream wise velocity of over bank and in bank becomes more complex thus highly turbulence in the area near the vegetation.

Title: Formation of a calculation model determining optimal rate of stoping face movement with a large deformation of a rock massif
Author (s): V. Fomichov, V. Pochepov, V. Sotskov and O. Mamaikin
Abstract:

An effective calculation model of a computational experiment that adequately describes the change in a condition of geotechnical model in time considering the change in geometry of contours of investigated galleries was developed. An analysis of mining-geological and mining-technical conditions of a stoping area was carried out. The experience of performing mining and development during a long wall mining method and applied constructive-technological coal extraction schemes, mathematical modeling of geo mechanical processes in a geotechnical system was studied. Stress-strain state, manifestations of rock pressure, conditions for maintaining the galleries depending on mining-technical and technological parameters were investigated. Measurements in operating galleries of Dolzhanskaya-Kapitalnaya mine which has similar mining-geological conditions to determine the deformation characteristics of a gallery contour were performed. A calculation model was developed, which was later used to predict a stress-strain state (SSS) of the rock massif in the conditions of Belitskaya mine. The analysis of obtained data allowed determining the values of the optimal rates of stoping face movement, depending on the structure and mechanical characteristics of a coal-bearing rock massif.

Title: Electronic properties of semi conducting zigzag (10, 0) carbon nanotubes due to uniaxial strain
Author (s): Irfan Dwi Aditya, Widayani and Suprijadi
Abstract:

In this paper we report the study of the change in electrical properties of zigzag carbon nanotubes (10, 0) under uniaxial compressive and tensile deformation using Density Functional Theory (DFT) calculation. There is an energy gap of 0.972 eV between occupied and unoccupied region in the optimized structure calculation. We found that the band gap of the semi conducting zigzag (10, 0) CNTs decreases as the strain increases for both compressive and tensile deformation. Different profiles of charge density appear for tensile and compressive deformations. The charge density of compressed state is more localized in the z direction of C-C bonds. Meanwhile, charge density of elongated state is localized in the diagonal C-C bonds direction. At the large tensile strain, the C-C bonds break at the z-direction C-C bonds. ICOHP analysis shows that the bond strength of CNT drastically decreases under tensile deformation.

Title: Design of compact dual-mode fractal based microstrip band reject filter
Author (s): Hayder S. Ahmed, Ali J. Salim, Mohammed R. Hussan, Hussain A. Hammas, Mahmood T. Yassen, Saad Mutashar and Jawad K. Ali
Abstract:

In this paper, a combination of the dual-mode technique and the fractal based resonator geometry has been adopted to design a compact band reject filter. The proposed filter structure relies mainly on that of the triangular patch resonators with an embedded slit structure. The Koch fractal geometry has been applied to the uncoupled side lengths of the triangular patch resonator. The filter structure has been modeled, and its performance is evaluated using the commercially available method of moment (MoM) based simulator, Sonnet. Results imply that the resulting dual-mode response seriously affected by the uncoupled side lengths of the triangular patch resonator. The consequences of varying the Koch indentation angle and the slit length on the resulting filter performance have been explored. Simulation results have confirmed the validity of the proposed resonant structure to realize a compact dual-mode stop band microstrip filter.

Title: Experimental study on flow around airfoil by using dielectric barrier discharge (DBD) plasma actuator
Author (s): Farah Ayiesya Zainuddin, Nazri Md. Daud, Shafizal Mat and Zolkafle Buntat
Abstract:

This experimental study was focused on the usage of DBD plasma actuator for enhancement aerodynamic performance of airfoil model NACA 0015. The DBD plasma actuator was able to suppress flow separation near the leading edge by disturbing airflow near that region. It can be seen that continuous small scale vortex is produced near the leading edge and it flows near the airfoil surface. Experimental works were performed at Reynold number approximately 63000 to 252000 with external airflow 5 m/s, 15 m/s, and 20 m/s. A thin plasma actuator was installed on NACA 0015 with 190 mm chord length and 260 mm span length at x/c = 0.025, where x is the vertical distance measured from leading edge and c was the chord length. Lift force measurement, measurement of pressure distribution on upper surface of airfoil and flow visualization were conducted to investigate the effectiveness of DBD plasma actuator. The experiment was tested during plasma ON (actuation) and plasma OFF (baseline case). The result shows that actuation case may increase lift coefficient compare to baseline case.

Author (s): Gorokhov Yury V., Konsanyinov I. L., Belyaev Sergey V., Gubanov Ivan Y., Uskov Igor V., Kirko Vladimir I., Lesiv Elena M., Koptseva Natalia P. and Strigin A. S.
Abstract:

A methodology for upgrading the hot die's technological forging processes was developed to increase forgings' economic efficiency based on computer modeling in QFORM and DEFORM-3D software packages. "Mounting Bracket" and "Disc" hot die forgings, made of aluminum alloys, were selected as the process for the upgrade. Meanwhile, the improved efficiency of technological process must not be connected to replacement of the utilized deforming equipment, considerable renovation of the pressing tool, or any changes in the form and size of the die forgings. Analysis of the existing technologies of the forgings' manufacture provided a basis to define an objective for computer research, namely, reducing the quantity of forging transitions via optimization of the contact friction, temperature, and speed conditions of metal deformation. As a result of forging with the use of new technology developed based on computer modeling, the forgings whose geometry and properties met the normative documentation requirements were produced in one transition in a factory environment. Meanwhile, the prime cost of their manufacture dropping by at least 10%.

Title: Droplet-like bent multimode fiber sensor for temperature and refractive index measurement
Author (s): N. Sidek, A. I. Azmi, M. A. A. Razak, M. R. Salim, A. S. Abdullah and M. Y. Mohd. Noor
Abstract:

This work proposes and demonstrates a bent multimode interference (MMI) sensor for refractive index and temperature measurement. The MMI structure was fabricated by successive splicing between single-mode-multimode-single-mode (SMS) fibers. A droplet-like bent was introduced in the multimode fiber section for excitation of modes into the acrylate coating. The excitation of higher modes into the acrylate coating is particularly interesting due high thermo-optic coefficient of acrylate which could improve temperature sensitivity, while evanescent field interaction of modes at the acrylate surface with surrounding material could be used for refractive index sensing. These modes experienced phase changes due to temperature and/or refractive index changes, consequently shift the spectra of the sensor. The sensor structure was simulated using BeamProp software to determine the required bending to excite light into acrylate coating for sensing. In experiment, a 3.5 mm bent sensor demonstrated refractive index sensitivity of 42.41 nm/RIU tested with refractive index between 1.30-1.395. Meanwhile, temperature sensitivity of 1.317nm/°C was attained using 5 mm bent sensor between 25 °C to 35 °C. The low cost and simple sensor structure is desirable in many applications including for detection, diagnosis, and determine of health, safety, environmental, liquid food, and water quality control.

Title: A novel game theory scheme to egest larceny in cockroach topology wireless sensor network (WSN)
Author (s): A Muruganandam and R. Anitha
Abstract:

Wireless Sensor Network (WSN) deploys for remote monitoring applications namely healthcare monitoring, finance and military. The nature of WSN in certain application makes it impossible to inspect and repair the nodes physically at certain times. In such cases, an unwanted user can associate to the node and retrieve crucial information. Moreover, conventional routing mechanism include Dynamic Source Routing (DSR) scheme to transmit data to destination. In DST routing scheme the whole data shift from one node to other node. The routing mechanism pose a disadvantage when network deal with confidential data. We propose, a Game theory routing scheme to forward data to destination with secrecy. The objective is to transmit data to destination under compromised node condition, without sacrificing network parameters namely throughput, network lifetime, end to end delay and packet delivery ratio. The proposed routing scheme is simulated and the same implement in hardware for comparative analysis and validation.

Author (s): O. V. Chudina, L. G. Petrova, V. A. Aleksandrov, V. M. Zinchenko and O. N. Trifonov
Abstract:

This article discusses the issues of increasing the reliability of loaded machine parts by modifying the surface using laser heating. In order to increase the durability of vehicle differential axle a method of surface modification has been considered, which combines advantages of discrete alloying of steel surface upon laser heating, diffusion metallization, and nitriding. Combined technology of surface strengthening of engineering steels is proposed, which is comprised of laser alloying with chromium, subsequent diffusion metallization and nitriding in environment of dissociated ammonia. It is demonstrated that preliminary local alloying makes it possible to decrease processing temperature and to obtain diffusion layer thickness in two times higher in comparison with conventional procedures. Nitriding of surface alloyed steel 40Kh (0, 4%C, 1%Cr) increases microhardness of strengthened layer up to 17.5 GPa, promotes formation of transient layer which positively influences on wear resistance of parts, increases their durability.

Title: A conceptual framework of WMN enabled WBAN system for pilgrims’ health monitoring during Hajj in the kingdom Saudi Arabia
Author (s): Shah Murtaza Rashid Al Masud, Asmidar Abu Bakar, Salman Yussof, Ghassan Ahmed Ali and Vaskor Mostafa
Abstract:

Due to the hardship of expedition, instability, and fluctuation of rough weather, continuous walking, hassle and mental stress during the Hajj at Makkah in Saudi Arabia, many pilgrims get injured, sick and tired. Besides, those who are suffering from various chronic diseases may also contract severe heart, chest, abdominal, and kidney diseases along with some infectious diseases like influenza and thus complicate the overall physiological functions of the patients. Other than the problems of diseases, overcrowd at religious sites also cause other noteworthy problems including trauma, missing and lost pilgrims, and even death. And so, it is a vital issue and a big challenge to provide the best healthcare facilities and services for pilgrims and their real-time monitoring during Hajj. Wireless body area network (WBAN) is a promising technology for healthcare. But, providing suitable communication network between WBAN and healthcare providers is another challenging issue. Modern information and communication technology (ICT) systems can make it feasible that WBANs will connect itself to the Internet to transmit data and efficiently administer the proper delivery of healthcare services among the pilgrims during Hajj. Therefore, integration of the medical technology and ICT in the healthcare sector is a prominent research issue especially for WBAN. However, the coverage of a WBAN is limited to only about 1-2 meter. Therefore, to largely extend its coverage area it should interwork with other wireless networks which will facilitate connectivity between those sensor devices of WBAN and the outside world. Due to the limitations of self-expandable, self-configuring and self-healing nature of other existing conventional wireless communication technologies, wireless mesh network (WMN) is the suitable and potential communication technology for transferring pilgrims’ health information to the healthcare stations crowd environment at Hajj ritual sites. WMN, due to its self-expandable nature can be deployed with WBAN during Hajj for pilgrims’ health monitoring which requires extending the coverage of the environment. Therefore, the main objective of this research is to design a conceptual healthcare framework for pilgrims’ health monitoring during Hajj by integrating WBAN and WMN technologies.

Title: KCR PID auto-tuner algorithm applied to a FOT device
Author (s): Diego F. Sendoya-Losada
Abstract:

The aim of this study is to apply a PID auto-tuner to the FOT device and test whether the controller can follow a multisine reference input. The objective is that the nonlinear effects and distortions coming from the FOT device itself are corrected by the control action, such that the excitation signal of interest is delivered to the patient. In this phase, the closed loop control will be designed for a hypothetical patient: a respiratory tube and a rubber balloon. The underlying reason is because it is necessary to ensure repeatability of the experiments, in order to check the feasibility of implementing a closed loop control strategy in the lung function device. The final aim is to develop the closed loop control for the case when the patient is breathing.

Title: An empirical approach to predict software development effort using linear regression model
Author (s): M. Pramod Kumar, M. Babu Reddy and A. Lakshmi Lavanya
Abstract:

To develop qualitative software products in a given schedule it is necessary to estimate the software effort. The effort estimation is helpful to the project managers to determine effort required to complete qualitative software products. In this paper we proposed a novel linear regression model based on software size metric. We applied proposed regression model on 60 real time BPO projects. The proposed regression model considers a linear relationship between size and effort. To validate the accuracy of regression equation, we calculated R^2 value. We used MMER and PRED(x) to calculate error rate and made comparisons with standard models. The proposed model has shown much closed and better results against some standard estimation models.

Title: Air pollution by emissions of heat sources
Author (s): Pavel Aleksandrovich Khavanov and Anatoly Sergeevich Chulenyov
Abstract:

In this publication, a comparative assessment of air pollution from sources of heat supply systems for a different type of development was carried out. A qualitative and quantitative assessment of the sanitary and hygienic indices of the air basin state is provided for the location of heat generating plants. Based on a comparison of quantitative characteristics, one can obtain the results of comparative calculations and the main qualitative indices of the technical solutions under consideration. The characteristics of the source of heat in each particular case were determined by the power of the heat source and the technical characteristics of the chimneys. It is revealed that the change in the dispersion zones taking into account the "wind rose" does not have a significant effect. It is received that the overlapping of dispersion zones in the housing and cottage heat supply is due to the density of construction and must be taken into account when developing architectural and planning concepts and technical solutions for heat supply.

Title: Real time statistically boundary detection
Author (s): Panca Mudjirahardjo, Raden Arief Setyawan and Hadi Suyono
Abstract:

The first task for object detection and recognition is image segmentation. This process is initialized with boundary detection. In this paper we propose a boundary detection method based on standard deviation value of intensity within the window. We assume that the low value is similar color where the computation process occur on the same object. While the high value, the computation process will occur on the object’s boundary or edge. In this research we compare to other methods to evaluate the performance of proposed method. The experimental result, by using window size of 3х3 pixels, our method’s computation time is 66.54 ms and using window size of 5х5 pixels, the computation time is 67.39 ms. Video rate is 15 fps. Processing with the proposed method yields less noise compared to other method, both for color and grayscale processing.

Title: Missing link prediction in collaborative research based on Triadic Analysis
Author (s): Akila Venkatesan and Govindasamy Vaiyapuri
Abstract:

Researchers, academicians collaborate in academic institutions to perform research. Most of the time, the outcome of this collaboration is in the form of Co-authored paper publication. The Co-authoring of research papers can be modeled as a network. In this context, many works have been done about the link prediction in Co-authorship networks. To predict whether a link will appear or not, each pair of nodes within the network is assigned a score called similarity or proximity. The links having higher similarity score are supposed to be of higher existence likelihoods. So far, majority of previous works in link prediction focus on the application of similarity measures such as Common Neighbors, Jaccard Coefficient and Simrank, in order to predict new connections in the future. To analyze and understand any evolving network, it is necessary to study not only the link formation but also the link dissolution. Link dissolution is a relatively new problem. This paper addresses Unlink Prediction based on (1) Social Embededdness with Network Overlapping and (2) Social Embededdness with Triadic Analysis. The experiments are conducted using the bibliographic dataset from DBLP-ACM. The results shows that the proposed work performs better in terms of Precision and Recall.

Title: A state of the art review on beams on non-uniform elastic foundations
Author (s): Adel A. Al- Azzawi and M. H. Al-Madani
Abstract:

This research is a review on previous work on linear elastic behavior of beams resting on uniform and non-uniform Winkler foundation. Several methods were used previously by other researchers starting from analytical and numerical such as series, finite difference and finite element formulations which are developed to solve various problems. The finite element method is formulated previously by using beam, plate and solid 3D elements to model beams and spring elements to model Winkler foundation in the past. Also, the finite difference coded in MATLAB and Fortran was used to formulate the problems to deal with various variables using Gauss Jordan and Gauss elimination to solve them and to compare with the results. Also, the Fourier series coded in various computer program to obtain the results and used to check and compare with the results obtained from other methods. In both methods, Fourier series and finite-difference, the formulations are based on the basic differential equations. The results obtained from previous studies using different methods are given and discussed together to compare and check the accuracy of the solutions. Good agreement is found in these methods, which indicate the efficiency of these methods which was used by previous studies.

Title: Wheel and shoe forced cooling at conform installations

Abstract:

A current trend in nowadays metallurgy is to create combined technologies that cover several metallurgical treatment procedures or various operations performed on a single device dedicated to manufacturing required products and thus ensuring the manufacture of competitive products at minimal production costs. The forms in which the technological operations in metallurgical production are combined may vary. Most effective is the combination of casting and plastic metal working processes. However, during the crystallization of molten metal in an annular groove of the disc and subsequent pressing, a considerable amount of heat is generated, and part of it shall be removed to establish the isothermal conditions while carrying out the continuous casting and pressing process. Otherwise, unstable temperature in the pressed articles exiting a die channel may lead to mechanical properties' dispersion and the distortion of their geometry in length as well as at cross section of the pressed articles, thereby lowering the products' quality. It should be noted that the pressed article is destroyed when a temperature similar to the melting temperature of the pressed metal is achieved, which shall be considered as an ultimate defect. Moreover, increased pressing temperature decreases the strength of the tools, which leads to their premature failure. One of effective ways to solve this problem is forced cooling of both the pressing tool and metal section. This paper presents various technical solutions aimed at solving this problem.

Title: Model predictive controller (MPC) for a MIMO process
Author (s): Kavery Lal, Rakesh kumar S. and Valarmathi R.
Abstract:

Model Predictive Controller (MPC) is one of the advanced methodology in current control engineering which has become the attractive strategy that deals with linear/non-linear dynamic behavior of the system. Linear MPC approach is used in this work for the quadruple tank system by taking the lower two tanks into account. The aim of this work is to design and investigate the predictive controller for controlling the level of tanks in a quadruple tank process based on constrained and unconstrained type of problems. Various disturbance scenarios were also applied and proved by controller to show a good response to disturbance rejection. The best possible control is achieved by tuning the parameters of MPC based on a tuning algorithm. The controller is thus designed in the MATLAB environment and according to the gathered simulation environment results, the applied control method were best suitable for obtaining optimal control and the results were analyzed by performance measures.

Title: Milling tool condition monitoring using acoustic emission
Author (s): Chockalingam P., Ervina Efzan M. N. and Natarajan C.
Abstract:

Milling of T6-6061 aluminium alloy material is a complex and challenging process due to the difficulties in finding the optimum milling process parameters for achieving the desirable properties such as surface roughness and optimum tool life. The parameters selection is generally based on the skill and knowledge of the technicians involved and number of time consuming trial and error runs. The experiment presented involved measuring the acoustic emission during the milling experiment with different spindle speeds and feed rates. It has been found that spindle speeds and feed rates have the highest effect on the cutting of the aluminium alloy thus also influencing the tool wear.

Title: EOQ inventory model for time dependent deteriorating products with quadratic time varying demand, variable deterioration and partial backlogging
Author (s): R. Kavitha Priya and K. Senbagam
Abstract:

In this article we present a suitable EOQ Inventory model for deteriorating items having time dependent demand, allowing shortages. We have considered a variable deterioration rate which is sensitive to changes in time. The demand rate is assumed to be a quadratic function of time. The permitted shortages are considered to be partly backlogged. The backlogging rate is changing and reliant on the length of the following renewal. The mathematical formulation of the model is first developed and solved analytically to minimize the average inventory cost. Finally we have discussed the proposed model with a numerical example and analyzed its sensitivity to change in parameters.

Title: Development of a speech controlled android drawing application for handicapped people
Author (s): Lukas Klinghammer, Muhammad Akbar Ibnu Farhan and Wansu Lim
Abstract:

A big margin of the handicapped people still do not have the same possibilities to express themselves and further advance their personality as the majority of the population. The control and use of smart phones proves to be a big challenge for them. Applications controlled by speech serve as a substitution to the finger controlled based applications that dominate the market. Through the use of such applications the handicapped have the chance to experience the life of the unburdened. Based on those implications the development of an application to support the artistic needs of the handicapped was imminent. The developed application achieves the support by being fully controllable by speech. The development proved to be a possibility but the limiting factors of the mobile phones and the pocketsphinx library hindered any groundbreaking results. Nonetheless the application allowed for a base research on the still small field of accessibility applications.

Title: Real time safety system for women
Author (s): Sakthi Prabha R.
Abstract:

In today’s world, women and girls still feel unsafe to travel alone whether it is a day or night. Now-a-days women are been attacked by men irrespective of their ages. Women are facing various problems which include robbery/theft, rape, molestation, eve-teasing and various other difficulties. Keeping this in mind, a device has been modeled which offers a hands-on help to the women in danger with a single press of a switch/button. This device helps the women in danger to be easily located with the help of global positioning system (GPS) and also messages and calls are given to alert their respective emergency contacts which are already stored in the microcontroller using global system for mobile communication (GSM). Hence this device serves handy when any women traveling outside feel insecure about her surroundings. The benefit of this system is that it provides the exact location (both longitude and latitude) of the person in danger.
