In an electric power day-ahead market, market prices are not always cleared at marginal cost caused by the strategic bidding of generators. This paper presents the results of day-ahead market simulation by using a simple three-generation-companies’ model for the case of demand with price sensitivity and analysis of the profits depending upon bidding strategies. The results show that, without a demand response, generation companies with diverse generation can increase their profit by strategic bidding. Moreover, under this condition, even if the demand response is made sensitive, these characteristics do not change. It is clarified that one of these factors is the operating constraint of power generators. If the generation company’s low-cost power generators decrease, the company’s profit monotonically decreases as the speculated capacity increases. However, realizing this case requires an unreal demand response and many small companies without diverse generation. Unless the conditions above are satisfied, the wholesale power transactions only through a day-ahead market without price-sensitive demand mechanisms would create a sellers′ market, where the sellers can easily manipulate the price.

In this paper, laser micro-patterning software developed for manufacturing of printing rolls for printed electronics is presented. The software consists of a servo control module, an image processing module, a configuration module, and a laser patterning module. By the software, laser beam's position and irradiation are controlled according to drawing patterns while the pattern roll is rotating. In this operation, control performance is important to determine the quality of the pattern roll and manufactured electronics after printing. The software is developed based on the accurate control algorithm and optimization of laser operation over the whole image for computation time and high-speed patterning. Additionally, overlapping image patterning is considered for the uniformity of the engraving depth and patterning quality.

Controlling the dynamics of ionic liquids (ILs) is a significant issue for widespread use. Metal–organic frameworks (MOFs) are ideal host materials for ILs because of their small micropores and tunable host–guest interactions. Herein, we demonstrate the first example of an IL incorporated within the micropores of a MOF. The system studied consisted of EMI‐TFSA (1‐ethyl‐3‐methylimidazolium bis(trifluoromethylsulfonyl)amide) and ZIF‐8 (composed of Zn(MeIM) 2 ; H(MeIM)=2‐methylimidazole) as the IL and MOF, respectively. Construction of the EMI‐TFSA in ZIF‐8 was confirmed by X‐ray powder diffraction, nitrogen gas adsorption, and infrared absorption spectroscopy. differential scanning calorimetry and solid‐state NMr measurements showed that the EMI‐TFSA inside the micropores demonstrated no freezing transition down to 123 K, whereas bulk EMI‐TFSA froze at 231 K. Such anomalous phase behavior originates from the nanosize effect of the MOF on the IL. This result provides a novel strategy for stabilizing the liquid phase of the ILs down to a lower temperature region.

In this paper, a nonlinear position control controller based on singular perturbation theory is proposed. Since the dynamics of a PMSM involves slow and fast models, singular perturbation theory can be applied. Applied conditions and stability proofs are studied. The proposed control design procedure is simplified and robust to variations in the inductance. High-bandwidth control effort for the current tracking is not required, but position and velocity measurements are necessary in the proposed method. The simulation results validate the performance of the proposed method.

Abstract A tracking simulator that runs in parallel with the plant and perfectly simulates the plant behavior has been developed. This tracking simulator is currently in the validation phase at a commercial plant site. The tracking simulator strongly depends on the physical model based on physical and chemical laws, and it cannot simulate unknown phenomena in the plant. A hybrid model consisting of a physical model and a statistical model using the historical plant operation data was proposed. The estimation accuracy of the statistical model was improved using the virtual input from the tracking simulator. Although the Kalman filter technique is applied to conventional software sensors for quality estimation as a model updating function, deterioration of estimation accuracy is often seen with marked changes in plant behavior and the analyzers shut down. To resolve these issues, we applied Just-In-Time modeling based on the historical data modeling technique with the tracking simulator, and the plant model coverage of the tracking simulator was expanded for various processes.

Component-Based Software development Framework for 3rd Party Logistics Business

This paper suggests a component-based software development framework for 3rd party logistics (3PL) business. This framework integrates two engineering methodologies in order to identify the most reusable software components that can be used in several types of 3PL business models. UML (Unified Modeling Language) is used to design lower-level software components and dEMO (design and Engineering Methodology for Organization), one of the business engineering methodologies based on the communication theory, is used to identify core business processes for 3PL business models. By using the methodologies, we develop a 3PL management solution by applying the framework into a C2C type of 3PL business model, specifically the door-to-door (d2d) service.

IEEE Symposium on Product Compliance Engineering (PSES)

Functional safety of embedded systems has become an integral part in automotive engineering activities due to the forthcoming safety standard ISO 26262. One main challenge is to perform development activities compliant to the standard and provide the respective documentation. Traceability between requirements from a standard, as well as project-specific process and product artifacts throughout the entire development cycle allows compliance assessment to support qualification. This paper proposes a methodology to plan and monitor the safety development process. Using a formalized requirements library of the ISO 26262 as well as a system description and its safety integrity level, a standard compliant process model is derived describing all necessary steps in the development process. Based on this process model, the methodology allows monitoring process activities and their degree of implementation, based on standard compliant confirmation measures. The main benefit is the reduced effort in preparing qualification or certification of a new safety-critical product. The development of an Adaptive Cruise Control system is sketched as an example application to illustrate the proposed proceeding.
