One of the tasks in steganography is extend area in the cover media for embedding more secret messages with enhancing security key and then extract messages with minimum error. In this direction, this paper propose hiding gray images inside a color image based on steganography Least Significant Bits method (LSB) with shuffling by using two types of 4-D chaotic system (Lu and Liu). The color image (RGB model) separated into three cover images (red, green, and blue) and each one of these three cover images may be used to hide 3-shuffled secret images. 4-D chaotic system provide an efficient security key and more difficult to forecast attack. Peak signal to noise ratio (PSNR) and mean square error (MSE) proves that both of secret and cover images are retains its explicitness and characteristics after reconstruction in the receiver.

The power that flows through the links of a split- power gear train are formulated in terms of velocity ratios and local efficiencies. The power flow directions are deduced by nomograph method. The power losses are deduced by potential power method. The two methods are used to complement each other to study the efficiency of the Simpson gear train. A single equation is derived for the overall efficiency. Despite the simplicity and clarity of the current method, its results are consistent with what is available in scientific literature. The effect of the number of teeth, gear ratios, and overall speed ratio on the overall efficiency are also studied.

Surface Water area (SWA) extraction is an important part of water resource management and has been the hottest topic in the remote sensing of water resource sector for over two decades. An approach is presented to estimate the change of area of surface water over 15 year period (2003 - 2018) using a time series of Landsat images. Twelve Landsat scenes were used to spatially and temporally cover Duhok Governorate, Kurdistan region-Iraq. A modified normalized different water index (MNDWI) were employed to quantitatively estimate the SWA and coincidently analyzed with the temporal change of precipitation and temperature data. Results show that the considerable decrement of SWA is observed from 2003 to 2008 with reduction of 51%. This is also was confirmed by metrological used data. Moreover, an increment of SWA is noticed from 2008 to 2013. However, a slight increment was realized between 2013 and 2018. In addition, during the studied period a climate conditions (temperature and precipitation) in Duhok Governorate have been changed significantly. These changes could have affected the SWA, but so also could external human interference.

Multipath propagation phenomenon often causes Inter-Symbol Interference (ISI) because several copies from the originally transmitted signal travel in different directions and reach the destination with different time delays. This paper offers a new diversity technique to eliminate the effect and utilise multipath propagation phenomenon. The new diversity technique is known as MultiPath Forward Error Correction (MPFEC) technique. The MPFEC technique considers some of the multipath copies as an existing resource (redundant copies of the transmitted signal) which can be utilised to enhance the performance of Forward Error Correction coding (FEC) techniques, hence saving significant channel resources otherwise given to a feedback channel, without adding redundancy. Two different coding techniques BCH and RS coding are used in the simulation to perform the Bit Error Rate (BER) analysis. The result reveals that BCH and RS codes performance can be enhanced by utilising the MPFEC technique without increasing the number of redundancy. This paper is implemented by using MATLAB. The results are analysed and compared.

A nonlinear forward model named VSLite is used to simulate tree ring-width growth from climate data. There is always uncertainty in such data inputs, which might influence the uncertainty of the model outputs. The present work performs a Bayesian sensitivity analysis (BSA) to the VSLite model using a Gaussian process emulator. BSA aims to understand and quantify the uncertainty of the model’s outputs due to a change in its inputs. The model was successfully implemented at different geographical locations around the world. To examine the accuracy of the model, we first compared real tree-ring data at different locations with those simulated from VSLite. The variability in the model output was then explored and quantified via BSA. Results show that BSA has successfully classified model parameters in terms of their influences on the model output variation.

Mimicking natural phenomenon of social insects, such as bird flocks and insect colonies by merging randomness facility and some other simulation rules, are the core tasks of the artificial meta-heuristic algorithms. Such algorithms are the most efficient and powerful techniques used to solve various complicated real-world optimization problems. Firefly algorithm, which belongs to nature meta-heuristics algorithms, is inspired by mating and flashing behavior or the phenomenon of bioluminescent communication of fireflies in the nature. In this paper, a hardware structure design for firefly algorithm has been proposed. Firefly algorithm is executing sequentially as all meta-heuristic algorithms, due to the nature of the algorithm. Therefore, sequential hardware structure design for the algorithm using Finite State Machine (FSM) system has been proposed. The hardware design structure implementation is mapped into a FPGAs (SPARTAN 3XS1600) device. Numerical results of the comparison between the hardware and the software (using C++ programming language) implementation of Firefly algorithm were obtained. These results indicate that the hardware implementation is executed 461 times faster than the software implementation. Indeed, the required execution time for finding the optimal solution can be reduced rapidly using the proposed hardware design structure.

Waste management is one of the fundamental services untaken by municipalities to retain cities clean and healthy. It represents a high priority and urgent issue for many communities around the world. Rapid progress in the economy and urbanization has had a significant impact on the increase in waste disposal volumes. In this study, Geographical information system GIS was suggested and implemented for optimizing the waste collection (WC) routes in Al Hillah city. The ArcGIS Network Analyst model was developed to improve the efficiency of WC in the Municipality of Hillah (MoH), through the redistribution of waste collection bins and improved trucks routing in terms of distance and time. Sixty routes are resulted and optimized to minimize the total distances of the current route. Simultaneously, it helps in reducing the time required for each route to complete the waste collection process. The final result shows about 30% of the aggregated route distances are minimized in addition to the resulted duration times. The optimal scenario suggested in this study is found to be more efficient in terms of assembly time and distance traveled by waste trucks.

In present work, AISI 309 stainless steel studs were joined to AISI 1020 carbon steel sheets by arc stud welding technique. A range of welding currents and times were applied to investigate the effect of welding parameters on microstructure and mechanical properties of the weldments. The microstructure observation revealed that increasing of welding current and time encourages martensitic transformation in heat affected zone of carbon steel and gives a high possibility to the formation of sigma phase in fusion zone of stainless steel. Microhardness test showed highest hardness of 575HV in fusion zone at 800A welding current and 0.35s welding time because of hard and brittle sigma phase. The strength of the joints was evaluated using torque test. Maximum torque strength of 60N.m was registered with 400A and 0.35s that also showed the best weld integrity. A crack was detected in the fusion zone at 800A welding current due to the difference in thermal expansion coefficient between stainless steel and carbon steel.

The vast progress of embedded low-cost, low-power Wireless Sensor Network (WSN) technology has prompted researchers attention to exploit this technology in applications those require real time voice transmission. By equipping WSN devices with some extra components, the devices are able of streaming or transmitting voice in real-time. This paper is aimed to propose, implement, and evaluate (using performance evaluation parameters: one-way delay, jitter, B.W, and CPU usage) the performance of a framework to be used for processing, compressing and streaming voice to a remote computer over Wi-Fi (IEEE 802.11) network using a Raspberry Pi3 (RPi3) and open source FFmpeg technology. The framework has to be configurable to use AC3, MP3 and OPUS audio encoding algorithms with different sampling rates. For voice streaming, this paper presents unreliable transport mechanisms involving combinations of MPEG-2 Transport Stream (MPEG-2 TS) container, Real Time Transport Protocol (RTP) and User Datagram Protocol (UDP). To keep the cost low, the operating system used within this research is the Raspbian and the device driver is Advance Linux Sound Architecture (ALSA).
