Path tracking control for car-like robots by pid controller with time-varying parameters

Wheel mobile robots have been widely applied to many areas of life, from serving people in services and industrial logistics to military fields. Applications of wheeled mobile robots such as floor cleaning robots, supermarket robots, logistics robots in hospitals, autonomous robots that guide automatic guidance in intelligent factories, military robots and agricultural robots. Thereby, we can see the great potential of mobile robots in the future. However, among the wheel mobile robots, the differential-drive mobile robot structure is most commonly used because of its simplicity in structure and control. Nevertheless, the navigation and driving are done synchronously through the two drive wheels, which leads to slippage and difficulty in controlling posture errors when navigating, especially on roads curved with a small radius. In order to overcome the disadvantages of the steering and navigation of differential-drive mobile robots, the structure of the automobile has been applied to design a wheel-mobile robot called a car-like robot. Many studies have shown that the advantage of this design option is that the navigation control and robot drive are separated. As a result, the dynamic control loop can ignore the navigation part, while the kinematic model determines the navigation law. Therefore, the work proposes the design of a PID controller with time-varying parameters for a car-like robot to track a given trajectory with minimum error. The nonlinear kinematic model of the robot is linearized along a reference trajectory, and the obtained linear model is used in the controller design process. A PID controller is designed where the controller parameters are tuned to minimize the tracking error. Our model achieves a tracking error value, including the minor position is 5.1 mm, and the maximum postural error is 2o. The simulation results showed the proposed controller's effectiveness in position and posture errors, and it shows we can apply this research to control car-like mobile robots in logistics services.
ViSTORY: Effective Video Storyboard Generation with Visual Keyframes using Discrete Cosine Transform

Nowadays, multimedia content utility is increasing rapidly.Multimedia search engines like Google, Yahoo, Bing, etc., are available just a click away to all users.There are around 500-600 hours of video uploads per unit of time to the Internet.So, among other types of multimedia content, such as text and images, video is the most complicated content for indexing, browsing, and retrieval.Videos give more scope for implementation because of their complex and unstructured nature.This paper proposes a new method of video storyboard generation with keyframe extraction in spatial and frequency domains using Discrete Cosine Transform (DCT) for video summarization.It discusses the empirical appraisal of video visual keyframes with t-test analysis in comparison with spatial and frequency domains, resulting in a quick response to customer demands by providing static storyboards.This study proposes a new performance measure as matching frames by analyzing input videos and the standard benchmarks video dataset, i.e., Open Video Project (OVP) and SumMe.Among all the keyframe extraction techniques, DCT gives higher accuracy and a better matching rate.
Evaluation of Dispersion for Soil Properties from Faw City- Southern Iraq

Four boreholes were drilled in four different places of the AL- Faw city using a hand auger, disturbed samples were collected at depths of 0.5 and 1.5 meters. The soil of the study area was determined by classification tests to be silty clay, CL-type soil in the Unifined Classification System of Soils. Soil dispersion tests such as the Crumb test, chemical analysis and XRD tests were conducted, and the results of crumb test showed that the soil of the study area was low dispersive from grade 2 except for the fourth site was a non-dispersive soil. The values of Total Salts Dissolved (TDS) in the pore water of the soil, was determined by estimating the total concentration of dissolved cations (Na, K, Ca and Mg) .The ETDA titration technique (for Ca and Mg) and the flame photometer were used to test this pore water (for Na and K), and it showed that the soil of the study area in the four sites within the C zone represented the Intermediate dispersive soil classification chart, and the results from Sodium Absorption Ratio (SAR) values showed that the soil in the area was dispersive.&#x0D; The XRD data showed that the minerals quartz, calcite, dolomite, and clay made up the majority of the soil samples. The principal clay minerals included Smectite (Montmorillonite), Palygorskite and Kaolinite. The results of the Total dissolved salts test showed a variety of the Crumb test for a difference in the soil content of mineral and chemical components. It is necessary to conduct further research on the XRD analysis with detailed interpretation of the minerals present, the importance of clay mineral types like Smectite should be assessed. The study of dispersion processes, the identification and classification of soils from specific tests and the identification of soils are the main objectives of this research.

Encrypting of Text Based on Chaotic Map

Background:&#x0D; Due to the internet's recent rapid expansion, security has become a crucial issue when transmitting digital data via unsecure channels. This can be applied by employing dependable encryption methods. This research brought forward a text encryption system order to create safe databases.&#x0D; Materials and Methods:&#x0D; The research uses a chaotic map based on a logistic map Due to its widespread application in scientific research. Several processes are used to carry out the encryption activity. Firstly, the text is formatted in 2D matrix of numbers converted into vector. Secondly, to create a sequence for using it in the encryption process, the chaotic system is employed. Thirdly, sorting the generated vector in order to scramble the text values based on it. The final step involves encoding the scrambled text using a mathematical operation. Also, there are many steps used in the decryption process. In the first step, the same mathematical technique is used to decrypt the encrypted text after the identical chaotic sequence has been generated. In the second step, the scrambled values are descrambled to obtain the decrypted text.&#x0D; Results:&#x0D; The experimental results demonstrate that the suggested approach obtain an excellent value of entropy equal to (0.9955) and Correlation coefficient equal to (-0.0024) and Avalanche effect equal to (0.5120) as well as the proposed system examined under NIST tests and obtain a good results (&gt;0.01) and examined for multiple other files and obtain a good results, in terms of execution time tests, the proposed system applied in a short amount of time.&#x0D; Conclusion:&#x0D; The proposed system matched the criteria for encryption techniques in terms of high sensitivity for initial values, high security, high randomizing Whatever text is to be encrypted. Also the proposed system can be applied for real time application due to its Short implementation time.
Linearly immutable continuously time series modelled bivariate stochastic processes with vector values: Distinguishing features

Certain observations are assumed to be missed while studying finite continual extended Fourier transformations of time series with precisely stable (i+j) vector values. This is assumed to be the case. This is because the procedure requires studying extended finite Fourier transforms in a standardized manner. The goal is to get as close to an exact interpretation of the results as possible with the data at hand. The results will be put to use in decision-making, which is why this is being done. As a result of this new data, the continuously Fourier transformation will take a starring role in the findings. Asymptotic moments are currently receiving a lot of consideration from researchers all over the world. Case studies on the topic of electrical energy will be used to test our theoretical concepts.

On the Generators of Quantum Dynamical Semigroups with Invariant Subalgebras

The problem of characterizing GKLS-generators and CP-maps with an invariant von Neumann algebra [Formula: see text] appeared in different guises in the literature. We prove two unifying results, which hold even for weakly closed *-algebras: first, we show how to construct a normal form for [Formula: see text]-invariant GKLS-generators, if a normal form for [Formula: see text]-invariant CP-maps is known — rendering the two problems essentially equivalent. Second, we provide a normal form for [Formula: see text]-invariant CP-maps if [Formula: see text] is atomic (which includes the finite-dimensional case). As an application we reproduce several results from the literature as direct consequences of our characterizations and thereby point out connections between different fields.
