“…When we have started with the docking, first thing we considered is Estart and then simultaneously Emin and Emax. These values are to be considered energy should be minimized so as to make the molecule stable as, more the rotatable bonds in ligand, the more difficult it will be to find good binding modes in repeated docking experiments [42], [44], [46]. Thus final result that is the Etotal should lie in between Emin and Emax.…”

Concentrates on ligand receptor connection is a critical region in new medication discovery program for different targets, sinsce cell surface receptor is recognized as perfect focus for some drug targets. In this study, protein and ligand will be used as it is in lock and key model respectively. Sub-atomic docking might be characterized as an enhancement issue. We observed that the both tertiary structure of protein and ligand were more compatible with high binding affinities, a "submit glove" similarity is more suitable than "lock-and-key". Throughout the procedure, the ligand and the protein alter their compliance to accomplish an in general "best-fit" and this sort of structural modifications bringing about the general restricting is alluded to as "initiated fit". The focal point of atomic docking is to computationally animate the sub-atomic acknowledgment process. The point of atomic docking is to predict the graphical model using in silico methods to improve the compatibility between two targets with the end goal that the free vitality of the general framework is limited

In this paper, we propose and assess SWAPN, a useful, novel and intelligent dream tool to study the impending multimedia technologies and to help the visually challenged as well as aged persons to overcome their disabilities. Recently, there were many research studies conducted related to human-machine systems available to help visually challenged people to reassure themselves to the outside world as normal individuals. We also propose a novel methodology to explore the uses of multimedia tools using Image Sensor, Camera, Laser Sensor, Inductive Proximity Sensor and Hand-held device to develop a ubiquitous environment to model the Human Computer Interaction (HCI) system. This methodology embraces the advantage of present Smartphone technology to help the people who are visually challenged from birth and also the aged persons who suffer from either full or partial vision loss. The newly introduced features like motion detection and feature extraction capabilities of SWAPN are assessed by realizing the implementation of machine-tomachine features for the modest usage. We have also inherited the usage of social networking for the visually challenged. Often more useful features like warning detection systems which notify the user the present weather conditions and inform for sudden changes in temperatures also been included.

Abstract. The purpose of this paper is to present a multichannel ultrasonic range finder which was designed for the navigation system for blind people. A substantial number of consultations with blind people in the Blind People Centre in Krakow have shown that the navigation and obstacle detection with a help of a white stick only, is not sufficient enough to assure a high safety level. Electronic aids which are being designed for blind people should be mobile, comfortable and low-powered. That is why the MOBIAN c (a mobile safety system for the blind) project is being carried out by the authors to create a highly reliable safety navigation system for blind people. It could not only improve blind people quality of life but also their safety, especially when they are walking in unknown areas. As a part of this project, the multichannel ultrasonic range finder was designed, produced and tested. The tests have proven the device is capable of detecting objects from different directions in a range over 4 m. The device interface is easy to manage and can be controlled by almost any microcontroller or FPGA chip. The designed range finder is to be implemented in the electronic assistant project for blind people. Other systems, including the industrial ones, for instance, mobile robots or gates that count people entries, could benefit from this multichannel range finder. Usually, some low-cost ultrasonic range finders use two transducers for each channel (a transmitter and a receiver). The designed device employs only one transducer per channel which minimizes the end-device size and cost and at the same time provides with the main functionality. Novelty of this device is its multichannel design and the emplacement of the ultrasonic transducers, which can be used due to the application of the multichannel analog multiplexer. Thus, it is possible to detect obstacles, even the inclined ones, with higher reliability and increase the safety of blind people while walking. Also, this design and the transducers' placement allow to detect obstacles much quicker, when the blind user suddenly turns.
