A searching algorithm was found to be effective in producing acutely needed results in the operation of data structures. searching is being performed as a common operation unlike other operations in various formats of algorithms. The binary and linear search book a room in most of the searching techniques. Going with each technique has its inbuilt limitations and explorations. The versatile approach of different techniques which is in practice helps in bringing out the hybrid search techniques around it. For any tree representation, the sorted order is expected to achieve the best performance. This paper exhibits the new technique named the biform tree approach for producing the sorted order of elements and to perform efficient searching.

The optimal Latin hypercube designs have been applied in many computer experiments as a basic method of experiment design. In this paper, we propose a novel criterion for constructing optimal Latin hypercube designs. The corresponding foundation of the novel criterion ideas is that the each point of the uniform design should have approximately equal distance with adjacent points. It means if we count the average and variance of distance between each point of design with its adjacent points, then the minimum variance of those distance will be a new criterion for optimal Latin hypercube designs. Only limit adjacent distances has been chosen to count above variance for convenience. The criterion come from limit variance will have an effect on the uniformity of a design. So another criterion was proposed that is maximum average adjacent distance. The final criterions are synthesized by minimum variance and maximum average of the adjacent distance which are connected by a coefficient. A novel searching algorithms was also proposed that take advantage of the columnwise-pairwise algorithm and the simulated annealing algorithm. The novel searching algorithm only could be used to the criteria above mentioned because it use some special information connected with the adjacent distance deviation. A software has been programmed that can generate Latin hypercube designs with the proposed criteria and searching algorithm. The properties of different criterion and searching algorithm were compared by generating large quantity designs and count the statistical properties of criterion. The result from some case of designs can account that the proposed novel criterion and searching algorithm is better than other distance criterion and searching algorithm.

Contrary to conventional protecting data such as cryptographic techniques which encrypt the data with a secret key, secret sharing takes an approach to ensure well protection of transmitted information by allowing a secret message M to be divided into n pieces. Secret message M can be held by n participants to avoid the secret from incidentally or intentionally being lost. In a secret sharing scheme, secret information leaks from shadows, attack on shadow image, and large shadow image issues which has arisen when developing an algorithm. Although existing algorithms provide remedies for such problems, the computational complexity of existing algorithms is still questionable. Therefore, we propose a low computational complexity Quadri-Directional searching algorithm (QDSA) for secret image sharing. Experiment results show that the proposed algorithm ensures that generated shares are of high quality and no secret information is leaked from these shares, thus it guarantees high security of our scheme.

Memories play an essential role in computer systems as they store and retrieve data that may include instructions required for system operation. In the case of an assembler, the memory stores instructions such as the Opcode table (OPTAB), which contains the instructions in the form of machine language to implement the desired program. A search operation is required for the Opcode table to obtain the desired instruction. To improve the speed of search operations and overall system efficiency, there are various search operation algorithms and techniques available, including linear, binary, and hashing algorithms. However, they all share one critical aspect which is they rely on software-based techniques that counter difficulties with the von Neumann Model. In this paper, we introduce a hardware-based approach to enhance the search operation for OPTAB in assemblers, which is usually performed using software-based techniques. Our proposed method involves replacing the conventional Random Access Memory (RAM) with Binary Content-Addressable Memory (BiCAM), which enables parallel search operation within a single clock cycle. To demonstrate the effectiveness of our approach, we utilize the *** assembler as a case study. We provide a comparison of our proposed method with the RAM-based searching algorithm used in *** assembler. Time complexity analysis and a comparison of resource utilization and power efficiency are provided. Our results showed that the proposed method has a fixed time complexity of O(1) under all conditions, regardless of memory size or input size. An increase in both resource utilization and power efficiency has been observed in the BiCAM due to its hardware structure. However, it could still be considered a reasonable trade-off for time-sensitive applications.

Multi-access Edge Computing (MEC) plays a crucial role in reducing latency and enhancing the Quality of Experience by bringing cloud services to the network edge. One of the primary challenges within MEC is ensuring seamless handovers between servers, specifically during end-user mobility, without disrupting active sessions. To address this challenge, we propose the Server Search and Select algorithm Protocol (SSSAP), a standardized protocol designed to manage handovers across heterogeneous MEC networks. SSSAP leverages the User Datagram Protocol (UDP) to guarantee low latency and fast transmission. It gives a structured approach for handover decision-making, utilizing real-time network metrics to enhance session continuity, inspired by the architecture of Transmission Control Protocol (TCP). By establishing a scalable framework for seamless interoperability in MEC environments, SSSAP ensures uninterrupted service delivery, reduces handover latency, and improves network performance. SSSAP is particularly relevant as MEC evolves to support next-generation technologies.

This paper presents the kinematic calibration of a four-degrees-of-freedom (4DOF) high-speed parallel robot. In order to improve the calibration effect by decreasing the influence of the unobservable disturbance variables introduced by error measurement, a measurement configuration optimization method is proposed. Configurations are iteratively selected inside the workspace by a searching algorithm, then the selection results are evaluated through an index associated with the condition number of the identification Jacobian matrix;finally, the number of optimized configurations is determined. Since the selection algorithm has been shown to be sensitive to local minima, a meta-heuristic method has been applied to decrease this sensibility. To verify the effectiveness of the algorithm and kinematic calibration, computation validations, pose error estimations, and experiments are performed. The results show that the identification accuracy and calibration effect can be significantly improved by using the optimized configurations.

This paper presents a new means to control the processes involving energy conversion. Electric machines fed by electronic converters provide a useful power defined by the inner product of two generalized energetic variables: effort and flow. The novelty in this paper is controlling the desired energetic variables by a Data-Driven Control (DDC) law, which comprises the effort and flow and the corresponding process control. The same desired useful power might be obtained with different controls at different efficiencies. Solving the regularization problem is based on building a knowledge database that contains the maximum efficiency points. Knowing a reasonable number of optimal efficiency operation points, an interpolation Radial Base Function (RBF) control was built. The RBF algorithm can be found by training and testing the optimal controls for any admissible operation points of the process. The control scheme developed for Permanent Magnet Synchronous Motor (PMSM) has an inner DDC loop that performs converter control based on measured speed and demanded torque by the outer loop, which handles the speed. A comparison of the DDC with the Model Predictive Control (MPC) of the PMSM highlights the advantages of the new control method: the method is free from the process nature and guarantees higher efficiency.

The ability to find optimal egress routing is critical for safe and effective firefighting processes. This article presents a novel smoke emulator that can be used to provide this ability in firefighting processes. It has two fundamental components: 1) a sensor network based on the Internet of Things (IoT) and 2) a simplified computational fluid dynamics (CFD) smoke simulator based on Navier-Stokes equations. Supported by IoT, real-time events, such as door opening and window breaking, can be detected, and the relevant information can be used to update the variables in CFD to ensure high accuracy and relevancy. A long short-term memory (LSTM) is employed to evaluate the values of any sensors temporarily malfunctioning. A two-level of A* routing algorithm (Nosrati et al., 2012) has also been developed to optimize the egress routing for evacuees with an aim to minimize the time of smoke exposure. Simulation studies demonstrated that this smoke emulator helps significantly improve the firefighting process's safety and effectiveness.
