Abstract- This paper presents the Generalization of Wall Panel Theory (GWPT), placing the walls that make up the column in a structural core shape with an angulation different from orthogonality. As for the geometry of the structural core C and double T, the inclination analysis of the walls is performed in order to diminish the sheer forces for the effective structural launching for columns, seeking to minimize the stresses with the mere change of the wall inclination. Finally, we use the particular case of double T core with walls orthogonal to each other and validate the generalized formulations in this article, concluding the total resumption of the values of sectoral ordinates. In addition, the first three modes of vibration of the C cores and double T are used, in conclusion, 95.89 % and 95.81 % of convergence between the values obtained via CMT and FEM, respectively.

Abstract- Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of infrared light through an optical fiber. The light is a form of carrier wave that is modulated to carry information. Fiber is preferred over electrical cabling when high bandwidth, long distance, or immunity to electromagnetic interference is required. This type of communication can transmit voice, video, and telemetry through local area networks or across long distances. Optical fiber is used by many telecommunications companies to transmit telephone signals, Internet communication, and cable television signals. Researchers at Bell Labs have reached a record bandwidth distance product of over 100 petabit × kilometers per second using fiber optic communication. To fulfill the current requirements of Atomic Energy Center, Dhaka considering its smooth operation of high-speed internet service, optical fiber based network is the state-of-the-art network solution. An optical fiber network design refers to the specialized processes leading to a successful installation and operation of a fiber optic network which includes determining the type of communication system(s) which will be carried over the network, the geographic layout, the transmission equipment required and the fiber network over which it will operate. Atomic Energy Centre, Dhaka (AECD), considered as the pioneer institution of the Bangladesh Atomic Energy Commission (BAEC) is now one of its research establishments located at the core of Dhaka city was established in 1961 to carry out research and development activities in the field of Nuclear science and technology for peaceful purposes. For that, here internet is essential. So optical fiber network design and deployment at Atomic Energy center is very important.

Department of Computer Science, University of Engineering and Technology, Lahore, Pakistan

Abstract- At present the currency recognition for visually impaired and blind people has becomes a vital topic for the researchers in the different applications. The money exchange is an important part of our daily life activities. But it becomes very difficult for visually impaired and blind people to recognize the currency values in the financial exchanges and they easily betrayed by the other people. Accordingly, there seems an urgent requirement to scheme a framework that is useful in recognizing paper money notes accurately. There is a huge area for currency differential detection and it has evolved over many years. The paper explores currency identification and provides a comprehensive overview of the current literature on techniques for identifying currency notes, encouraging the survey effort to provide an effective system for blind and visually impaired people.
