PROBLEM: Dust contamination in metal mining poses substantial dangers to environmental quality and human health. Modern mining operations cannot use traditional spray dust suppression methods because they are poorly adapted to changing climate conditions, low efficient, and detrimental to the environment. INTRODUCTION: Dust pollution seriously impacts the environment and human health in metal mine operations. Traditional spray dust suppression technology has many problems, such as limited effect, environmental impact, and poor climate adaptability. OBJECTIVES: The purpose of this article is to develop a new type of spray dust suppression material and predict its dust suppression effect through algorithm simulation. Firstly, efficient and environmentally friendly dust-reducing materials were screened, and after evaluating the dust-reducing effect under laboratory conditions, the optimal material combination was determined. METHODS: Using computational fluid dynamics (CFD), a numerical model of the spray process was constructed to simulate the dust suppression effect of different materials under different climatic conditions. RESULTS: The results show that the highest dust reduction efficiency of the new spray dust reduction material is more than 4.3% higher than that of the traditional material, and it shows good stability. CONCLUSION: The new spray dust control material and its effect prediction method studied in this article provide an effective solution for dust control in metal mines, which has important theoretical value and practical application prospects.

To increase redundancy repair efficiency and thus final yield in embedded-memory cores, we propose Raisin, a redundancy analysis algorithm simulation tool that can calculate an RA algorithm's repair rate, yield, associated memory configuration, and redundancy structure. Raisin lets users easily assess and plan redundant elements and subsequently develop BIRA algorithms and circuits, which are essential for BISR of embedded memories.

学位级别：硕士

Visual algorithm simulation (VAS) exercises are commonly used in Computer Science education to help learners understand the logic behind the abstractions used in programming. These exercises also present problems common in the daily work of Computer Science graduates. Aalto University uses the JSAV library to create VAS exercises and evaluate the solutions submitted by students. The evaluation process counts the amount of correct steps given by the user during the exercise. However, because more detailed data is not collected, teachers currently can not recreate and analyse the submitted solutions more in depth. This thesis presents the design, development and evaluation of an application prototype, which can be easily integrated in existing VAS exercises created with the JSAV library. The prototype is called Player Application, and it is designed as a service that can be easily integrated into other systems while still remaining independent. The Player Application consists of two main independent components: the Exercise Recorder and the Exercise Player. A third important contribution is the new JSON-based algorithm Animation Language, which is designed to describe, structure and store the data collected from the VAS exercises. The prototype was successfully tested in an online environment by importing the Exercise Recorder into existing exercises and replaying the submitted solutions in the Exercise Player. The tests showed that its design and architecture were valid. Next, the aim is to create a mature application, which can be used at Aalto University and other institutions, in addition the prototype still needs further development to support more VAS exercise types.

This paper presents an in-depth study and analysis of oil painting classification and simulation using an improved embedded learning fusion vision perception algorithm. This paper analyzes and models the image quality evaluation problem by simulating the human visual system and extracting quality perception features as the main entry point to improve the prediction accuracy of the overall algorithm. This paper proposes a multi-classification method of CCNN, which uses the similarity measure based on information first to achieve multi-classification of artwork styles and artists, and this part is the main part of this paper. This paper uses the wiki art repository to construct a dataset of oil paintings, including over 2000 works by 20 artists in 13 styles. CNN achieves an accuracy of 85.75% on the artist classification task, which is far more effective than traditional deep learning networks such as Resnet. Finally, we use the network model of this paper and other network models to train the classification of 3, 4, and 6 categories of art images. The accuracy of art image classification by this paper's algorithm is higher than that of the current mainstream convolutional neural network models, and the extracted features are more comprehensive and more accurate than traditional art image feature extraction methods, which do not rely on researchers to extract image features. Experiments show that the proposed method can achieve excellent prediction accuracy for both synthetic distorted images and distorted images.

A Fast Time-Domain algorithm for the simulation of Switching Power Converters

引用

IEEE TRANSACTIONS ON POWER ELECTRONICS 1990年第3期5卷 363-370页

作者： Luciano, Angelo M. Strollo, Antonio G. M. Univ Naples Dept Elect Via Claudio I-80125 Naples Italy

A new efficient algorithm for the simulation of switched-mode power converters is developed. A Chebyshev series expansion is employed to effectively solve the differential equations describing the system in each topology. The power of the new simulation technique lies both in the simple but accurate polynomial approximation for the state transition matrices and in the ability to explicitly obtain the instants at which the switching of the circuit topology takes place. The case of a rapidly varying input forcing function can also easily be analyzed. Examples illustrating the generality and the computational efficiency of the new algorithm are presented.

A stable algorithm for simulation of array induction and measurement-while-driving logging tools

RADIO SCIENCE 1998年第4期33卷 949-956页

作者： Tian, X Liu, C Shen, LC Univ Houston Dept Elect & Comp Engn Houston TX 77204 USA

A stable numerical method to simulate array induction and measurement-while-drilling (MWD) logs is presented. The algorithm is based on a horizontal eigenmode expansion method. Mode propagation in the vertical direction is described by three-layer modules. Within each module, general transmission and reflection coefficients are obtained by tracing the propagation of the modes. The multilayer cases are treated as a cascade of such modules. Owing to the mode-tracing algorithm, numerical stability and efficiency are superior to the other methods. This numerical algorithm is applied to the simulation of array induction and MWD logs in formations with both vertical and horizontal layers.

A New Parallel algorithm for simulation of Spin Glasses on Scales of Space-Time Periods of External Fields with Consideration of Relaxation Effects

We have investigated the statistical properties of an ensemble of disordered 1D spatial spin chains (SSCs) of finite length, placed in an external field, with consideration of relaxation effects. The short-range interaction complex-classical Hamiltonian was first used for solving this problem. A system of recurrent equations is obtained on the nodes of the spin-chain lattice. An efficient mathematical algorithm is developed on the basis of these equations with consideration of advanced Sylvester conditions which allows one to step by step construct a huge number of stable spin chains in parallel. The distribution functions of different parameters of spin glass system are constructed from first principles by analyzing the calculation results of the 1D SSCs ensemble. It is shown that the behaviors of different distributions parameters are quite different even at weak external fields. The ensemble energy and constants of spin-spin interactions are being changed smoothly depending on the external field in the limit of statistical equilibrium, while some of them such as the mean value of polarizations of the ensemble and parameters of its orderings are frustrated. We have also studied some critical properties of the ensemble such as catastrophes in the Clausius-Mossotti equation depending on the value of the external field. We have shown that the generalized complex-classical approach excludes these catastrophes, which allows one to organize continuous parallel computing on the whole region of values of the external field including critical points. A new representation of the partition function is suggested based on these investigations. Being opposite to the usual definition, it is a complex function and its derivatives are everywhere defined, including at critical points.

With the continuous development of human computer interaction technology, large-size infrared touch screens have become an important interactive tool, and improving their recognition accuracy has become one of the important research directions. In order to understand the research status and trend of multi-touch recognition algorithm for large size infrared touch screen, based on extensive research of existing literature and latest achievements, two types of infrared multi-touch technologies based on different principles are first introduced, and then discusses three types of infrared multi-touch recognition algorithms: coordinate positioning algorithm, image processing algorithm and hybrid recognition algorithm. Through comparative analysis, it is found that the hybrid recognition algorithm has higher accuracy in multi-touch recognition, and the algorithm can be applied to large size infrared touch screen to improve the recognition accuracy. Finally, this paper summarizes the commonly used simulation platforms and functional and performance testing methods for infrared touch screens.

In this paper, a digital carrier recovery for a 60 GHz Radio-over-Fiber (RoF) system was researched. The system consists of three stages: optical 60 GHz carrier generation and mPSK data modulation with data rates up to 10 Gbit/s, simplex optical receiver (optical band pass filter and photo diode), and 60 GHz electrical coherent IQ down conversion. After the down conversion, the signal is digitized and the carrier recovery is performed to compensate for the electrical LO frequency offsets and phase drifts. The capability of using the well-established Viterbi & Viterbi algorithm as a carrier recovery solution for a 60 GHz RoF system was investigated. The proposed system was simulated by VPItransmissionMaker. The resulting data from the scenario has been processed by a MATLAB implementation of the V&V algorithm. The eye diagrams, constellation plots, phase plots, and cross correlation plots all verified the capability of the algorithm to compensate the phase shift as well as frequency shifts up to 5 MHz in our implementation, and emphasized the power of the algorithm in synchronization for RoF systems.

Experiences on automatically assessed algorithm simulation exercises with different resubmission policies

Journal on Educational Resources in Computing 2005年第3期5卷 7–es页

作者： Lauri Malmi Ville Karavirta Ari Korhonen Jussi Nikander Helsinki University of Technology Finland

In this paper, we present our experiences in using two automatic assessment tools, TRAKLA and TRAKLA2, in a second course of programming. In this course, 500--700 students have been enrolled annually during the period 1993--2004. The tools are specifically designed for assessing algorithm simulation exercises in which students simulate the working of algorithms at a conceptual level. Both of these tools allow students to resubmit their solutions after getting feedback. However, the resubmission policy has changed considerably during the period. Those changes reflect the students performance in the exercises. We conclude that an encouraging grading policy, i.e., the more exercises they solve the better grades they achive, combined with an option to resubmit the solution is a very important factor promoting students' learning. However, in order to prevent aimless trial-and-error problem solving method, the number of resubmissions allowed per assignment should be carefully controlled.
