Recently, basalt fibre reinforced polymer (BFRP) reinforcements are viable alternate to conventional steel reinforcements due to their high tensile strength, light-weight and good corrosion resistance. This paper presents the flexural response of concrete one-way slabs reinforced internally with BFRP and conventional reinforcements. A total of six concrete one -way slabs measuring 2000mm in length, 500mm in breadth and 100mm in depth were constructed. All slabs were tested under four -point bending over a clear span of 1800mm up to failure. The slab test results are described with regard to flexural capacity, deflection, crack width, and failure mode. It has shown that the ultimate load carrying capacity of BFRP slabs were greater than the conventional slabs. However, the BFRP slabs produce higher deflection and crack-widths compared to conventional slabs.

Recently, there has been a significant increase in the interest for robots. However, manually navigating a robot requires a skilled pilot who has highly constant concentration levels for sustained periods. Therefore, strong scientific interest has emerged in terms of developing solutions that allow a robot to navigate autonomously without needing constant human supervision. This is useful for a variety of potential applications ranging from surveillance and reconnaissance purposes, aerial filming, remote visual inspection of industrial sites, to military applications. First, a robot must be able to determine its location. Unlike humans, a robot does not have the sensing capacity and the ability to explore its environments and determine its location. Therefore, components like sensors need to be integrated on the robot. Examples of these sensors include GPS sensor, and accelerometer sensor. The robot then needs to be able to determine its destination and be able to create a route to get there. To do this, the robot must be able to generate paths to the destination and make a decision on which path to take. The FPGA DE0 Nano board offers a portable extensive computational platform that help to solve this current problem. It also has lower design complexity and the ability to be embedded to an outdoor robot localisation system. The path planning approach generates a route to the desired location. The GPS sensor was utilized to determine the positions for the current and desired locations. After information from the sensors was received, the DE0-Nano sent proper signals to the L293D to control robots motors. The DE0 Nano achieved a maximum operating frequency up to 1.3 GHz and total logic elements are 6,032. This means that the robot platform’s frequency requirements were achieved to that level. Thus, high performance was achieved by using FPGA with multi sensors.

The given paper proves that the key factors governing the design of the vacuum magnetic levitation transport system are the competitiveness of the new transport system and the safety of passenger transportation. This article draws attention to the similarities of the engineering problems when designing the passenger compartment of the vacuum vehicle equipped with the life support system and the aircraft. It allows using the aviation system design experience for development of a vacuum transport system. As the most similar prototype, the Japanese JR-Maglev high-speed system is considered. The assumption is made that the adaptation of JR-Maglev traction levitation system to the aviation technologies can become one of the directions to design a vacuum magnetic levitation transport system. For justification of this assumption, the layout diagram of the vacuum transport system adapted to the aviation fuselage is provided. The assessment of the energy consumption for the route is given. The vacuum transport system is compared with the airbus A320 in terms of specific energy consumption. The estimate calculations performed under the identical comparison conditions have shown that the vacuum transport system is much more effective than the aviation system.

Reversible data hiding in encrypted domain (RDHED) has greatly attracted researchers as the original content can be losslessly reconstructed after the embedded data are extracted, while the content owner’s privacy remains protected. Connecting the probable feature of public key cryptosystem, the proposed system utilizes elliptical curve cryptography for cost effective computation of secret keys required for performing encryption. Steganography process hides message into cover file and forms a stego file. In image steganography there is a need of method which will increase the security, reduce the distortion in the stego file and recovers the data without any loss. The proposed approach is the combination of data hiding technique and encryption. The image is encrypted using ECC to ensure user authentication. The key which are very confidential can be hidden into an encrypted image which is made a watermark image by applying the RDH (Reversible data hiding algorithm) without changing the bit stream size. Once receiver got encrypted stego file they can access the secret key by using a reverse process of data hiding. ECC is a superior option for open key encryption. It gives parallel security smaller key size.

Wheelchairs are seen as an important means of rehabilitation as they enable the disabled to move and exit from the isolation that can be imposed by his inability to move because of his paralysis or loss of legs or other disabilities as well as with the use of Illnesses and the elderly. The use of wheelchairs depends on the degree and the type of disability. The more the disability affects the movement of the individual whenever the need for chairs is necessary. Electric power is widely used in electric traction for many reasons: it is easy to control the speed of electric motor, the absence of exhaust gases, free of noise, it has high staring torque and it needs less maintenance than its mechanical counterpart. In the current research, a modern electric seat is powered using 220 ACV electric source to charge two batteries (12 VDC, 18-35 A/hr.) to supply 24 VDC input voltage for the electronic chopper (DC to DC voltage converter) as a source to DC motor type DG-168A1 which has a good and suitable specification: 24 VDC, 125watt, max drawn current 4.5 Ampere with maximum rotation speed 140 rpm. The classical mechanical energy by using his self-hands of the disabled is to move the wheel chair. In addition, two additional kinds of electronic devices are used for developing the control process. The second control device is electric battery charger which is used to adjust the two DC motors speed. Third control device is to regulate the sound signals to run the two DC motors. The wheel chair was tested in the University of Diyala/ Baaquba / Iraq on flat and tilted land steady state linear speed reached more than 0.9 m/s with a maximum weight was more than 100 kg. The design is subject to real electrical and mechanical engineering tests alongside using decades of applied equations on wheel chair to validate the experimental tests.

Abstract:

Channels typically introduce amplitude and phase distortions as well as inter symbol interference (ISI) to the received signals. Therefore, timing recovery is crucial when sampling the received waveforms at the correct instants. Specifically, we consider an iterative timing recovery technique which incorporates the error correction codes (ECC) owing to its robustness against poor signal-to-noise ratios (SNRs). These gains, however, are purely derived under the assumption of the additive white Gaussian noise (AWGN). The bit error rate (BER) performance of iterative timing recovery methods may suffer in non-Gaussian channels where impulsive noise exists. In light of this, we propose a novel suppression method to remove impulsive noise from the non-Gaussian channel before feeding the received signal to the iterative timing recovery unit. Results demonstrate that the proposed scheme can perform well even in non-Gaussian channels.

The formation of a high-quality casting surface is a complex process, determined by the nature of an alloy filling, heating the mold, physicochemical and mechanical interaction of the melt with the atmosphere of the mold, in the contact zone material-mold. On the one hand, the filler of the anti penetration wash should not be wetted by alloys, on the other hand, to form properties in the liquid state, the filler should be well wetted by a solvent. At present, the most common solvent used in the anti penetration wash is water. The purpose of this work is to study wettability of graphite activated by various methods i.e. by water and water - based systems. In the course of the process it was found that activated GKM is wetted by water worse (wetting angle is 90-120° depending on the method of preparing GKM than natural graphite (wetting angle of water is 55°). It was revealed that activated graphite is better wetted by water-based binding systems: depending on the activation method (mechanical, chemical and chemical-mechanical) the wetting graphite angle by 10% LST solution decreases from 49 to 37°; by 3.5% water bentonite slurry - from 69 to 50°; by water-based binding system containing 10% LST and 3.5% bentonite - from 54 to 40º.

This paper presents a novel approach in designing and implementing a laser-based wireless channel communication system. Both the transmitter and the receiver were successfully designed and implemented practically. The transmitter side consists of the input unit represented by a PS2 keyboard, a controlling unit achieved by a PIC16F887 microcontroller and a transmitting element represented by a 620 nm wavelength laser lens device for bit pattern transmitting. On the receiver side, a light-sensor made of light dependent resistor (LDR) is used as a receiving element by which laser beam, which is adopted to be the holder of the transmitted signal or data is sensed. Also, another PIC16F887 microcontroller is used as receiver controlling unit. In order to display data transmitting and receiving, a piece of display platforms is located on both sides. By uploading a firmware program in the PIC control unit, synchronization between receiver and transmitter has been achieved and verified. Data transfer is done through serial bit by bit technique. Therefore, the synchronization code ensures that the receiver should wake up and synchronize itself as soon as sensing new received data in order to keep the data in a correct order. The proposed work proved the simplicity in design as well as the low cost value PIC16F887 microcontroller. Moreover, the results of data transferring show an exceptional accuracy with an error-free system. However, data transfer is still obligated to the line of sight condition which requires the laser element to be accurately positioned in the path of the LDR receiving element. By real life system verifications, this work offer powerful satisfactory that will be cost- effective which in returns suits certain design and product requirements with respect to both cost and security.
