Abstract

This paper deals with the navigation problem of an autonomous non-holonomic mobile robot in partially-known environment. In this proposed method, the entire process of navigation is divided into two phases: an off-line phase on which a distance-optimal reference trajectory enables the mobile robot to move from an initial position to a desired target which is planned using the B-spline method and the Dijkstra algorithm. In the online phase of the navigation process, the mobile robot follows the planned trajectory using a sliding mode controller with the ability of avoiding unexpected obstacles by the use of fuzzy logic controller. Also, the fuzzy logic and fuzzy wall-following controllers are used to accomplish the reactive navigation mission (path tracking and obstacle avoidance) for a comparative purpose. Simulation results prove that the proposed path planning method (B-spline) is simple and effective. Also, they attest that the sliding mode controller track more precisely the reference trajectory than the fuzzy logic controller (in terms of time elapsed to reach the target and stability of two wheels velocity) and this last gives best results than the wall-following controller in the avoidance of unexpected obstacles. Thus, the effectiveness of our proposed approach (B-spline method combined with sliding mode and fuzzy logic controllers) is proved compared to other techniques.

Abstract

Morse code is a system of representation of letters, numbers, punctuation marks and signals using a code of dots and lines that are arranged to represent certain characters in the alphabet or certain signals (signs) that are agreed upon for use throughout the world was studied by nilas[1]. This code was coined by Samuel F.B. Morse and Alfred Vail in 1835 was studied by ming[2]. This research aims at how to apply the Background Subtraction method in the design of the morse sign language receiver in the invisible light. Build an Android-based application for recognition of Morse sign language by keeping messages sent using Morse sign language secret through infrared light from the sight of those who can read the message. From the results of the tests that have been carried out, it is concluded that the level of accuracy of testing using the False Match Rate (FMR) obtained a success percentage of 65% from the 26 character data tested. From the 26 character data tested, it was obtained data with the number of characters that were successfully counted correctly, namely 17 characters, while the character data that failed to be counted was 9 characters with a detection result of 26 characters.

Abstract

Social engineering is a common method to collect more information from victim trough socialization. This method employs human psychology to manipulate other people. In cyber society today, the attacker could use various methods to tapping into victim smartphone, and after that the attacker can get victim persona profiling information. The attacker can select random victim and then using wireless localization methods, the attacker could found its victim. After the random victim has been found the attacker can start social engineering directly to the victim based on persona profiling information, to gain trust and more personal information that can lead inflicting damage to the victim. In this paper, we demonstrate to localize victim using green obaidat calibrate Path loss Propagation models and $4 dollar device based on victim Smartphone RSSI Wi-Fi Signal. With this device we could localize a person within 15 meter with just only 0.64 dbm in difference between our RSSI measurement and simulation.

Abstract

In recent years, low power consumption has been an important consideration for the design of system since there is a high demand for consumer electronics such as cellphones for a longer battery life. This paper presents the simulation of half adder, half subtractor, full adder, and the full subtractor. The presented circuit contains NAND gates combining the NMOS and PMOS. These CMOS circuitries has the advantage of lower voltage, lower power consumption, and higher energy efficiency. The NMOS and PMOS were bridge together to produce the desired output. This design provides the CMOS half adder, half subtractor, full adder, and full subtractor using the Tanner EDA software tool. The complete CMOS circuit schematic are described in this paper. The design methods and principles are described thereafter. Simulations have been done with the use of the Tanner EDA tool in a CMOS technology standard and response output was verified comparing the obtained waveform along with its truth table. In comparison with conventional logic truth table, T-Spice output simulation matches with theoretical expectations.

Abstract

Patients after joint surgery require passive movements that are carried out continuously. The movement is given to the patient to reduce the stiffness that occurs in the joints after joint surgery. Joint stiffness is characterized by pain and limited motion of the joint, which is caused due to reduced synovial fluid. Synovial fluid in the joints can be reduced if the joint is not moved for a long time. This research will design a wrist joint therapy machine that can be moved flexion, extension, ulnar, and radial. Besides that, the device to be designed can be adjusted the angle of movement of the tool and the speed of movement of the tool. The angles of movement that can be reached are (1) flexion movement: 80 ° movement angle, (2) extension movement: 75 ° movement angle, (3) radial movement: 25 ° movement angle, and (4) ulnar movement: movement angle 39 °. Adjustable speeds include 1 RPM, 2 RPM, and 3 RPM. In the result of the testing device, we find the maximum difference of movement in 2° and the speed of rotation we have the difference in 0.5 seconds. Based on experiments that have been done, the tool can be controlled in accordance with the desired movement settings.
