Detection of string and column delimiters is a critical first step in the automated ingestion of files containing tabular data. In this paper we present an algorithm that uses a logistic-regression classifier to evaluate whether a particular choice of delimiters is correct. The delimiter choice that is given the highest score by the classifier is chosen as the one most likely to be correct. The algorithm...
The EU funded project RobLog recently developed a system able to autonomously unload coffee sacks from a standard container. Being the first of its kind, a further development is needed in order for the system to be competitive against manual labor. Financing this development entails a risk, hence a justified skepticism, which can be overcome by the longsighted view of the existing market potential...
Contra pose the character of scheduling problem in the aluminum industry, a virtual enterprise is abstracted in this paper. The VE substitute manufacturing techniques. A model of scheduling system during aluminum industry is also established based on a Multi-agent theory. As a foundation we will study the system model concerning every agent's working mechanism and the mechanism of corresponding with...
This paper studies the system identification, modeling and precision motion control of coreless linear motor drive stage which offers several advantages over its rotary counterparts in many applications requiring linear motion by eliminating mechanical transmission mechanisms. System identification is first carried out to capture the system dynamics characteristics. And with a precision motion control...
To solve the difficulty of precise locating of large inertia ball mill, a new method based on prediction is put forward. The feasibility of this method was analyzed using the motor theory and analysis on the ball mill kinematics and dynamics. The equipment to install rotary encoder that was connected to the ball mill was designed. And the testing hard ware based on single-chip microcomputer was build,...
This paper introduces the application of RFID (Radio Frequency Identification) technology in monitor and management of industry production process. After a full analysis the management of the mould in an aluminum profile treatment enterprise, the effective solution based on RFID technology is advanced. The complete scheme of real time trace information system about mould is introduced. This paper...
Discussing the impact of environmental factors in the supply chain management is a hot issue at home and abroad. This paper begins with a brief analysis of the contents of green supply chain management and the obstacles in the environmental management process. Then we do some research on how to carry green supply chain management out considering environmental management systems, by environmental management...
A method is offered to avoid the musculoskeletal disorders (MSDs) caused by electric tools and improve overall comfort. According to the method, The electric tool grips are designed according to the pressed human surfaces. The grips are replaced by clay models first. When holding the models, human body surfaces are deformed and recorded by clay surfaces. Simplify and rebuild the surfaces. Rapid prototyping...
A new type of heat-fading-resistance semimetal friction materials was prepared though changing traditional bond. The influences of a new high-performance bond on the semimetal friction materials were researched by way of contrastive experiments using different bond. The good performance of this bond is proved. According to the analyze of the experiment done in the defined rapid wear and rear machine,...
Nowadays, many new polymer materials have been widely used in different chemical production areas. The polymerization temperature is an important parameters of process control, but has characteristics of time-delay and inertial, so the ordinary PID control is difficult to obtain good effect. In order to control the system steadily and accurately, we suggest a compound control method, which combines...
There is still no research in the efficiency evaluation of distribution operation. So the aim of this paper is to fill the blank in this area of research. There are several innovations in this paper. First, the evaluation system of the distribution operation (not distribution center, distribution system or other organizations) was first put forward. Second, the DEA methodology was used to classify...
Chlorinated polyethylene(CPE), as a new type of polymer materials, has been widely used in plastics and rubber production. Temperature is the main parameter of process control. Because of the delay and inertial characteristics of temperature, the ordinary cascade control is difficult to obtain good control effect. So, we design a grey PID controller based on the principle of grey model. The simulation...
Fault diagnosis and protection is the key of safe running of power net. At present, the main studies of fault diagnosis and protection of power net (FDPPN) concentrate on the establishment and simulation of idiographic model, but there is not universal model. There is distinct limit between discrete character and continuous character in FDPPN, so that the paper extended HPN model to propose Hybrid...
The tracking control problem of muscular vessel systems with dynamic uncertainties and unknown parameters is studied. The unknown system parameters are adaptively identified, and the exogenous disturbance is attenuated by Nussbaum-type functions based on the backstepping methods. The derived adaptive robust controller guarantees that the closed-loop system is globally and uniformly bounded, and the...
In this paper we present a layered architecture for multirobot motion coordination. The purpose is to control and coordinate autonomous mobile robot with generic shapes and kinematics in a priori known environment. It is a centralized framework, where a leader robot (or a supervisor) plans the motion of all the robots and makes them moving synchronously. The architecture is layered, self-similar and...
An improved minimal resource allocating network (IMRAN) learning algorithm is developed for constructing radial basis function (RBF) network. The RBF network is adjusted on-line for both network structure and connecting parameters. Based on the proposed sequential learning algorithm, a direct inverse control strategy is introduced and applied to ship course-keeping control. Simulation results of ship...
Crude oil transportation is a central logistics operation in the petrochemical industry because the transportation cost of the crude oil represents a significant part in the cost of petrochemical products. In this paper, we consider the transportation by tankers or trucks. We show that under some realistic assumptions, this problem can be transformed into a single item lot sizing problem with limited...
Global logistics flows have increased dramatically in recent years due to the globalization in the world economy. It is more complex than the domestic logistics, consisting of multiple services like multi-modal transportation, cross-docking, storage, and customs clearance. Two issues are in order with multitude of services spanning across international borders: First, a single logistics provider may...
