Shedding light on the appropriateness of the (high) gasoline tax level in Germany
Germany imposes an energy tax of 0.65 € / l on gasoline which is one of the highest tax rates across countries. The effective tax is even higher when accounting for the consumption tax levied on top of the energy tax. Answers to the question whether such a high tax level is justified on efficiency grounds would add precious arguments to policy discussion debating the appropriate level of a ...


Short-Term Coalmine Gas Concentration Prediction Based on Wavelet Transform and Extreme Learning Machine
It is well known that coalmine gas concentration forecasting is very significant to ensure the safety of mining. Owing to the high-frequency, nonstationary fluctuations and chaotic properties of the gas concentration time series, a gas concentration forecasting model utilizing the original raw data often leads to an inability to provide satisfying forecast results. A hybrid forecasting model th...
On Analyzing LDPC Codes over Multiantenna MC-CDMA System
Multiantenna multicarrier code-division multiple access (MC-CDMA) technique has been attracting much attention for designing future broadband wireless systems. In addition, low-density parity-check (LDPC) code, a promising near-optimal error correction code, is also being widely considered in next generation communication systems. In this paper, we propose a simple method to construct a regular...


Storage Space Allocation of Inbound Container in Railway Container Terminal
Efficient storage strategy of railway container terminals is important in balancing resource utilization, reducing waiting time, and improving handling efficiency. In this paper, we consider the formulation and solution algorithm for storage space allocation problem of inbound containers in railway container terminal. The problem is formulated as two-stage optimization models, whose objectives ...
Asymptotic Stabilization of Continuous-Time Linear Systems with Input and State Quantizations
This paper discusses the asymptotic stabilization problem of linear systems with input and state quantizations. In order to achieve asymptotic stabilization of such systems, we propose a state-feedback controller comprising two control parts: the main part is used to determine the fundamental characteristics of the system associated with the cost, and the additional part is employed to eliminat...


Developing a Collaborative Planning Framework for Sustainable Transportation
Currently, as being the highest petroleum consuming sector in the world, transportation significantly contributes to the total greenhouse gas emissions in the world. Road transportation not only is responsible for approximately 20% of the total emissions of carbon dioxide in the EU and in the US but also has a steadily increasing trend in contributing to global warming. Initiatives undertaken b...
Experimental Evaluation of FSM-Based Testing Cost for Time-Delay Systems
With time-delay systems arising, time-delay system testing has attracted much attention. Additionally, evaluating the cost and effectiveness is required to make a good test strategy in practice. In this paper, we take time-delay and other five factors (state number, input number, output number, completeness degree, and accessibility degree) into account and present a timer embedded FSM (TEFSM) ...

The Application of Time-Delay-Dependent Control in the Transmission Effect of Monetary Policy on Real Estate Market
This paper uses a time-delay-dependent control model to analyze the transmission effect of monetary policy on the real estate market. We establish a theoretical framework between monetary policy and real estate market based on the three channels, that is, interest rate channel, monetary supply channel, and credit channel. Then we construct a basic model using control method. By analyzing the ef...
Global Appearance Applied to Visual Map Building and Path Estimation Using Multiscale Analysis
In this work we present a topological map building and localization system for mobile robots based on global appearance of visual information. We include a comparison and analysis of global-appearance techniques applied to wide-angle scenes in retrieval tasks. Next, we define multiscale analysis, which permits improving the association between images and extracting topological distances. Then, ...

Chaotic Behaviors of Symbolic Dynamics about Rule 58 in Cellular Automata
The complex dynamical behaviors of rule 58 in cellular automata are investigated from the viewpoint of symbolic dynamics. The rule is Bernoulli -shift rule, which is members of Wolfram’s class II, and it was said to be simple as periodic before. It is worthwhile to study dynamical behaviors of rule 58 and whether it possesses chaotic attractors or not. It is shown that there exist two Bernoul...
Linguistic Modeling of Pressure Signal in Compressor and Application in Aerodynamic Instability Prediction
Using conditional fuzzy clustering, a linguistic model for static pressure signal of compressor outlet in aeroengine was established. The modeling process and the validation result demonstrated unique advances of linguistic modeling in the analysis of complex systems. The linguistic model was used to predict the pressure signal before the engine entered instability. The prediction result showed...

OL-DEC-MDP Model for Multiagent Online Scheduling with a Time-Dependent Probability of Success
Focusing on the on-line multiagent scheduling problem, this paper considers the time-dependent probability of success and processing duration and proposes an OL-DEC-MDP (opportunity loss-decentralized Markov Decision Processes) model to include opportunity loss into scheduling decision to improve overall performance. The success probability of job processing as well as the process duration is d...

The aim of this paper is to develop a methodology for intuitionistic trapezoidal fuzzy multiple criteria group decision making problems based on binary relation. Firstly, the similarity measure between two vectors based on binary relation is defined, which can be utilized to aggregate preference information. Some desirable properties of the similarity measure based on fuzzy binary relation are ...
Temperature Control via Affine Nonlinear Systems for Intermediate Point of Supercritical Once-Through Boiler Units
For the operation of the supercritical once-through boiler generation units, the control of the temperatureat intermediate point (IPT) is highly significant. IPT is the steam temperature at the outlet of the separator. Currently, PID control algorithms are widely adopted for the IPT control. However, PID cannot achieve the optimal performances as the units’ dynamic characteristic changes at d...
