We investigated the characteristics of stock price manipulation. Two manipulation models were studied: pump-and-dump and spoof trading. Pump-and-dump is a procedure to buy a stock and push its price up. Then, the manipulator dumps all of the stock he holds to make a profit. Spoof trading is a procedure to trick other investors that a stock should be bought or sold at the manipulated price. We constructed mathematical models that use level 2 data for both procedures, and used them to generate a training set consisting of buy/sell orders within on order book of 10 dept.s. Order cancellations, which are important indicators for price manipulation, are also visible in our level 2 data. In this paper, we consider a challenging scenario where we attempt to use less-detailed level 1 data to detect manipulations even though using level 2 data is more accurate. We implemented feedforward neural network models that have level 1 data, containing less-detailed information (no information about order cancellation), but is more accessible to investors as input. The neural network model achieved 88.28% for detecting pump-and-dump but it failed to model spoof trading effectively.

Developing mathematical model for a process is an important and integral step in control system design process. Mathematical models can be developed from fundamental physical laws (white-box approach), by performing experiments (black-box approach) or a combination of both (gray-box approach). This paper presents a black-box system identification of a laboratory boiler. A mathematical MIMO model matrix which describes the dynamic behavior of the drum level and drum pressure of lab-boiler setup with respect to steam and feed water as manipulated variables is presented. A complete system identification of lab-boiler setup, designed by these researchers, has been carried out based on the design-of-experiments (DoE) and validated model with the field measurements. In this paper, the identified boiler-model is characterized in the form of 2×2 process transfer function model matrix structure. This 2×2 model matrix defines the dynamics describing the effect of changes in the feed-water flow rate and steam-flow rate, on the boiler drum-level and drum-pressure. This model can be used to study various classical and advanced control-design and analysis through this lab boiler setup.

Journal of Institute of control, robotics and Systems 2015年第3期21卷 276-282页

作者： Youn, Seung Geun Lee, Youn Ae Park, Tae Hyung Dept. of Control and Robot Engineering Chungbuk National University Korea Republic of

This paper proposes a SMD (surface mounting device) classification method for the PCB assembly inspection machines. The package types of SMD components should be classified to create the job program of the inspection machine. In order to reduce the creation time of job program, we developed the automatic classification algorithm for the SMD packages. We identified the chip-type packages by color and edge distribution of the images. The input images are transformed into the HSI color model, and the binarized histroms are extracted for H and S spaces. Also the edges are extracted from the binarized image, and quantized histograms are obtained for horizontal and vertical direction. The neural network is then applied to classify the package types from the histogram inputs. The experimental results are presented to verify the usefulness of the proposed method. © ICROS 2015.

This paper presents a visual touch recognition for NUKNatural User Interface) using Voronoi-tessellation algorithm. The proposed algorithms are three parts as follows: hand region extraction, hand feature point extraction, visual-touch recognition. To improve the robustness of hand region extraction, we propose RGB/HSI color model, Canny edge detection algorithm, and use of spatial frequency information. In addition, to improve the accuracy of the recognition of hand feature point extraction, we propose the use of Douglas Peucker algorithm, Also, to recognize the visual touch, we propose the use of the Voronoi-tessellation algorithm. Finally, we demonstrate the feasibility and applicability of the proposed algorithms through some experiments. Copyright © The Korean Institute of Electrical Engineers.

Different scripts are used for writing purposes. It is very much important to identify/know these scripts before an appropriate character recognition algorithm is chosen. This paper deals mainly on the various segmentation techniques available for handwritten script recognition system. It is an important technique for image processing. Image segmentation provides meaningful objects of the image. Identification of a script in handwritten recognition system is really a challenging task in real world. Many researchers are indulged in the recognition of scripts from handwritten documents over four decades. This task becomes more and more challenging when it comes to multi lingual/script country like India. An input Image is preprocessed through various steps and segmented by different available techniques. This identification of script helps in optical Character Recognition systems (OCR).

This paper presents a technique of PID controller tuning for fractional order industrial process and proposes a Time-Response Specification Based Fitness (TRSBF) function required by Particle Swarm Optimization (PSO) for the controller tuning. The results are compared with the conventional Integral Time Absolute Error (ITAE) based and analytic controllers. The performance and robustness is analyzed in time-domain and frequency-domain to establish the suitability of proposed fitness function. MATLAB/Simulink has been employed for PSO based tuning algorithm validation and comparison of parameters like peak overshoot, settling time, disturbance rejection time, stability in frequency domain, etc.

The paper aims to present an ultra-low power electrocardiogram (ECG) on chip with integrated fuzzy decision making (FDM) chip for body sensor networks. The proposed device is small in size, wearable, battery life. The proposed device has two designed chips: (1) ECG on Chip and 2) FDM chip. The ECG on chip contains an analog front end circuits, a 12-bit SAR ADC, a QRS detector and relevant control circuitry interfaces. The analog front end circuits accurately senses and digitizes the raw ECG signal, which is then filtered to extract the QRS complex with sampling frequency of 256 Hz. The obtained ECG details are sent to FDM chip for decision making where abnormalities are found and an alert signal is sent to the patient via microcontroller. The patient's ECG data is wirelessly transmitted to mobile phone or PC using ZigBee. The chip was designed and implemented in 0.35μm standard CMOS process. The digital circuits and SRAM operate at 3.3V. The total area of the device is about 6cm 2 and consumes about 8.5μW. Small size and low power consumption show the effectiveness of the proposed design suitable for wireless wearable ECG monitoring devices.

Spectral design of output feedback controllers for systems pre-compensated by input shapers

引用

IFAC-PapersOnLine 2015年第12期48卷 117-122页

作者： Pilbauer, Dan Vyhlídal, Tomás Michiels, Wim Dept. of Instrumentation and Control Eng. Czech Technical University in Prague Faculty of Mechanical Engineering Technická 4 Praha 6 166 07 Czech Republic Department of Computer Science Katholieke Universiteit Leuven Celestijnenlaan 200A Heverlee B-3001 Belgium

The primary objective is to investigate the applicability of spectral methods for designing feedback controllers for a closed loop system with an input shaper with time delays. The shaper is included in the feedback loop in order to pre-compensate low-damped oscillatory modes of a flexible subsystem. However, after inserting a shaper into the feedback loop, the closed loop dynamics becomes infinite dimensional. A robust controller design then requires guaranteeing that all the infinitely many poles of the closed loop system will safely be located in the left half of the complex plane. Besides, the closed loop dynamics need to be suficiently fast in order to take over and keep filtering properties of the input shaper. For the spectral design of the controller, the recently developed spectral abscissa minimization approach for interconnected time delay systems is applied. The presented methods are tested on a case study simulation example, which is a multi-degree of freedom mechanical system. © 2015, IFAC (International Federation of Automatic control) Hosting by Elsevier Ltd.
