In order to improve the identification efficiency of coins, a coin identification method based on image rectification and template matching is put forward. Firstly, the image of coins is separated from the whole image through background modeling; secondly, according to Fourier transform or Shape features, the image of coins which has been separated is corrected. Lastly, the coins are identified through the template matching aiming at the corrected image. Experimental results show that the proposed method is characterized by high accuracy, strong anti-interference ability and high identification efficiency.

With amazing frequency, most of us will open a bottle or other container and throw the cap away without thinking that it has any other use. However, while the end function of a cap is the same for almost all types and materials, caps use various mechanisms to achieve their main function, and come in a wide variety of materials, shapes, colors and other properties related to engineering and technology. For a teacher, caps can have a multitude of educational and pedagogical uses. In this "Caps: A Never Ending Resource in Teaching and Learning STEM/STEAM Education" project, we offer readers, teachers, and students some tools for understanding and using caps as valuable resources for teaching and learning various topics in STEM fields as well as to motivate students to engage in their own learning process as well as a pathways for introducing students to some concepts and applications in engineering and technology. In addition, we provide detailed instructions, including some hands-on activities that will help teachers master the concepts and the pedagogy.

Paper Title :: Study of Procurement Procedures on Manpower Oriented Services as Non-Consultancy Services under Publ
Author Name :: Sasidhar Parasa
Country :: India
Page Number :: 50-61
strategy for procurement of manpower oriented services such as Security Services, Housekeeping & Cleaning and Outsourcing staff for Drivers, Carpenters, Plumbers, etc., under the gambit of the Public Procurement is non-existent. The Government departments, PSUs, Corporations etc are employing different means and methods for employingmanpower on contract basis, resulting in confusion and disorder. Although guidelines are available on Minimum Wages under Minimum Wages Act, 1948, the procedures are not exhaustive on service contracts. The minimum basic rates of wages in respect of Skilled or Semi Skilled or Unskilled workers are linked to the Consumer Price Index (CPI) Numbers as per Part-I of the Schedule of the Minimum Wages Act,1948, published from time to time by the Government. The Cost of Living Allowance to be paid per each point of increase is also fixed by the Government. No guidelines are available to make these provisions as a contract document for legal obligation on both the parties of the contract. Further no guidelines are available for selection mechanism for an appropriate service provider, sparing few criteria such as Labour Registration, Labour Contract License, Service Tax registration, EFP & ESI registration etc. To overcome the problems associated with selection of service providers, payment of minimum wages and compliance with other statutory rules etc., in the framework of a contract agreement efforts have been made in specific areas to arrive at consensus guidelines. Based on this objective, estimates & tenders have been formulated with the regulations of the Department of Labour, Government of Telangana. Procurement procedures have been evolved in the Engineering Department of Jawaharlal Nehru Technological University, (Autonomous Institution) Higher Education Department, Government of Telangana under the Public Procurement Procedures. Procurement guidelines have been arrived based on detailed technical evaluations on a real time study between 2012-2016.

Traditional stacks have been the historical programming practice for most web applications developed around the globe, However, the trend is now changing. The advantages they provide can no longer meet the increasing need of the users. The focus of this study is to design and implement and email system as part of a telemedicine application using some emerging JavaScript technologies that include MongoDB, ExpressJS, Node.JS and Angular.JS. The benefits provided by these individual components are on the rise and can function as a single stack. This paper is relevant in studying the theoretical taxonomy, internal working principles and implementation of the M.E.A.N stack components. Bringing these components to work together through one common language of internal data communication (JSON) to build modern day web application is presented in this study. The test result shows that the technology provided a platform for easy user interactions and improved communication. The result of this study has proven the much-needed advantage of speed and flexibility of this technology when compared to other traditional stack such as LAMP or .NET.

Paper Title :: The Impact of Shear Wall Modeling Techniques on the Structural Response of Masonry Structures; a Concise Comparative Discourse
Author Name :: Samir H. Helou || Riad Awad
Country :: Palestine
Page Number :: 77-83
The local structural engineering industrycustomarilytreats masonry infill walls as evenly distributed dead load applied on relevant peripheral beams. Alternately, such minimally reinforced walls are normallymodeled as shell elements or occasionally neglected altogether. While the mentionedpractice maybe satisfactory when dealing with gravity loads, it maylead to erroneous and misleading results when considering lateral forces such as wind or seismic excitations. In such instances, the lateral stiffnessof the walls is neglectedwhile they inevitably addto the massof the structure.This potentially leads toadverse consequences resulting from the decrease in the associated fundamental frequency. Since seismicdesign is a requirement imposed by local governments and since Palestine lies on an active earthquake prone zone, the subject of adequate wall modeling within masonry structures deservesfocusedscrutiny.Moreover, in-fill masonry walls, whether reinforced or of plain concrete, characterize Palestinian vernacular construction,this considerably affects frame action.In a broad sense,concrete walls are considered as the first line of defense against seismic excitation. Furthermore, it is emphasized thatstructural modeling procedures profoundly impact, negatively or positively,the end result of any structural designundertaking. The following study brings such arguments into the lime light by focusing on a six-story single bay structure in which concrete walls are modeled in five different techniques, in addition to the reference bare frame model. The study is comparative in nature and limitedto a strict numerical discourse targeting the response dueto seismic excitation.Furthermore, a non-linear Pushover Analysis is carried out for two wallmodeling techniquesincorporatedinto a bare frame structure.

Paper Title :: On unsteady two-dimensional convective heat and mass transfer flow of incompressible viscous fluid through a vertical porous medium
Author Name :: M. M. Allan || Samah M. Dardery
Country :: Saudi Arabia
Page Number :: 84-96
In this paper we consider unsteady two-dimensional convective heat and mass transfer flow of a viscous, incompressible, electrically conducting optically thin fluid which is bounded by a vertical infinite plane surface. A uniform applied homogeneous magnetic field is considered in the transverse direction with first order chemical reaction. An analytical solution for two-dimensional oscillatory flow on unsteady mixed convection of an incompressible viscous fluid, through a porous medium bounded by an infinite vertical plate in presence of chemical reaction and thermal radiation are presented. The surface absorbs the fluid with a constant suction and the free stream velocity oscillates about a constant mean value. The resulting nonlinear partial differential equations were transformed into a set of ordinary differential equations using two-term series. The closed form solutions for velocity, temperature, concentration, skin friction, Nusselt number, and Sherwood number have been obtained, using the regular perturbation technique. Numerical evaluation of the analytical solutions were performed and the results are presented in graphical and tabular form. This was done to illustrate the influence of the various parameters involved in the problem on the solutions.
