An Innovative Lift Control Board Design and Prototype Production Using CANbus Communication System and STM32 Microcontroller

In this study, Önder Group Inc. Design Center, with an innovative approach, designed controllers for the first time, and prototypes were produced for a wide range of goods lifts according to different needs. With the innovative board design, goods lift users can choose parameters such as the number of floors, door types, and lock types from a user-friendly menu to suit their needs. Within the scope of the study, all functions that may be needed were identified, and the hardware structure of the system was determined. By simply changing the defined parameters, the desired goods lift controller can be made ready in a very short time. Time savings were achieved by simply expanding the hardware structure with the design of the CANbus communication system according to the number of floors and stops of the elevators. Thus, a wide range of lifts can be used by simply increasing the number of floor announcer boards and selecting the menu. Additionally, thanks to the designed Wi-Fi plug-in software, operators will be able to monitor the malfunction and operating status of the lift. With this plug-in, technical service teams can intervene immediately in case of malfunction.

DWT Lifting Scheme for Image Compression with Cordic-Enhanced Operation

This paper proposes an innovative image compression scheme by utilizing the Adaptive Discrete Wavelet Transform-based Lifting Scheme (ADWT-LS). The most important feature of the proposed DWT lifting method is splitting the low-pass and high-pass filters into upper and lower triangular matrices. It also converts the filter execution into banded matrix multiplications with an innovative lifting factorization presented with fine-tuned parameters. Further, optimal tuning is the most important contribution that is achieved via a new hybrid algorithm known as Lioness-Integrated Whale Optimization Algorithm (LI-WOA). The proposed algorithm hybridizes the concepts of both the Lion Algorithm (LA) and Whale Optimization Algorithm (WOA). In addition, innovative cosine evaluation is initiated in this work under the CORDIC algorithm. Also, this paper defines a single objective function that relates multi-constraints like the Peak Signal-to-Noise Ratio (PSNR) as well as Compression Ratio (CR). Finally, the performance of the proposed work is compared over other conventional models regarding certain performance measures.

A COORDINATED DOCKING APPROACH BASED ON EMBEDDED VISION

Docking is an essential yet challenging problem to the deployment of marsupial robotic system involving a mother robot and several child robots, as the technologies such as rail-line tracking and global vision measurement are not suitable for applications in unknown environments. This chapter presents a coordinated docking approach based on embedded vision of the child robot collaborated by the mother robot with an innovative lifting docking station. The child robot utilizes a complementary metal oxide semiconductor (CMOS) camera to capture and extract image features related to a benchmark attached on the docking station, and the internal correlation between its heading direction and the entry direction of docking station is then derived, which makes the docking process be concise and convenient. On this basis, a coordinated docking task model is built and the transition conditions among task states are presented. The precision analysis of the docking is also discussed. The experimental results prove the effectiveness of the proposed approach.

Model test investigation on an innovative lifting system for deepwater riser installation

An S-lay crane barge, named CNOOC 201, has been built for pipe laying in deepwater oil/gas fields in the South China Sea. It is due to be commissioned by the end of the year 2010. A special lifting system is developed to meet the challenge that installing deepwater risers from an S-lay barge is difficult and has not been achieved. The purpose of this paper was to investigate the model test on such an innovative system, which has to be done before field application. By applying the similarity theory, the movement of the S-lay barge is simulated through a six degrees-of-freedom motion platform, and a truncated model riser is utilized for the model testing. The displacement and force boundary conditions at the truncated position of the riser are obtained from the catenary governing equation and become realized by a slideway cart and a loading system designed to control the configuration of the model riser, which presents a similar configuration to a real riser in deepwater. The test results are in very good agreement with theoretical calculations, showing that the active truncated test is applicable for controlling the configuration of the deepwater riser in model testing investigation.

Dynamic Response of Chiral Truss-core Assemblies

ABSTRACT: Periodic cellular configurations with negative Poisson's ratio have attracted the attention of several researchers because of their superior dynamic characteristics. Among the geometries with a negative Poisson's ratio, the chiral topology features localized deformed configurations when excited at one of its natural frequencies. This is of particular importance as resonance can be exploited to minimize the power required for the appearance of localized deformations, thus giving practicality to the concept. The particular nature of these deformed configurations and the authority provided by the chiral geometry suggest the application of the proposed structural configuration for the design of innovative lifting devices, such as helicopter rotor blades or airplane wings. The dynamic characteristics of chiral structures are here investigated through a numerical model and experimental investigations. The numerical formulation uses dynamic shape functions to accurately describe the behavior of the considered structural assembly over a wide frequency range. The model is used to predict frequency response functions, and to investigate the occurrence of localized deformations. Experimental tests are also performed to demonstrate the accuracy of the model and to illustrate the peculiarities of the behavior of the considered chiral structures.

Induced Drag Minimization: A Variational Approach Using the Acceleration Potential

A method of predicting the minimum induced drag conditions in conventional or innovative lifting systems is presented. The method is based on lifting-line theories and the small perturbation acceleration potential. Assuming linearity and rigid wake aligned with the freestream, the optimal conditions are formulated using the Euler‐Lagrange integral equation subject to the conditions of fixed total lifting force and wing span. The Lagrange multiplier method is applied, and equations for the design optimum are obtained and solved directly. Particular attention is paid to the Hadamard finite-part integrals involved in the solution process. Munk’s drag theorems are also applied in order to verify the quality of the solutions. In this paper, where the theoretical/computational foundation is laid for the induced drag minimization of general lifting-line configurations, the case of the biplane under optimal conditions is extensively analyzed. It is demonstrated that, under optimal conditions, the two wings (which have the same wing span) have the same circulation distribution. Cases of finite, infinite, and infinitesimal distances between the wings are analyzed as well. It is shown that the optimal distribution is, in general, not elliptical. The proposed theoretical approach is general, and it offers a valuable tool for direct prediction of minimum induced drag in both planar and nonplanar lifting systems. Results obtained by the proposed approach shed light on some of the mathematical issues involved, and they can be used for verifying results obtained by numerical math-programming-based optimization.
