The station microgrid technology provides a flexible and efficient platform for the integration of distributed generation and renewable energy power generation technology and its application in substations. With the further upgrading of renewable energy power generation products and technologies and the further development of new energy technologies in substations, new energy and micro-grid technology...
Traditional substation station power are taken from the grid system, power consumption is relatively large, not only increases the power loss, but also the consumption of nonrenewable energy. With the development of micro-network technology, more power users tend to use the new micro-grid power supply mode to improve power supply reliability. In this paper, the power supply system of 500kv substation...
Defectivity is another critical aspect of Chemical Mechanical Planarization (CMP) processing and other than typical CMP induced defects: micro scratches, slurry particles, etc., there are other types of critical wafer defects that negatively impact process yields in Nano semiconductor process manufacturing. A case of an observational study draws that in comparison to reference levels, wafer functional...
The Oracle RDBMS In-memory Option (DBIM), introduced in 2014, is an industry-first distributed dual format in-memory RDBMS that allows a database object to be stored in columnar format purely in-memory, simultaneously maintaining transactional consistency with the corresponding row-major format persisted in storage and accessed through in-memory database buffer cache. The in-memory columnar format...
A novel effective robot base frame calibration method using Procrustes Analysis is presented. The errors from the design, manufacture and assembly of robot in the mechanism cause the deviation of nominal base frame used by the robot controller and the actual mechanical base frame. The actual mechanical base frame can be established by external precision measurement. The theory of Procrustes Analysis...
A new Clip Type Passive Manipulator, instead of the Scissors Type Manipulator, is studied and applied for solving the problem of samll capacity of the manipulator. When the capacity of the manipulator increases, the picking algorithm is considered for refilling process. The sequence of medicine storages is arranged in accordance with the picking algorithm, which is one improtant operational efficiency...
The Clip Type Manipulator, which includes moving unit and clip type manipulator unit, is designed for the Fast Medicine Dispensing System (FMDS). The modularization design technique is in favour of coordinated control among units and system maintenance. The permutation order of storage containers in the automatic refilling mode has been observed to have significant influence on the dispensing efficiency...
Considering customers' bounded-rationality purchasing behavior, this paper focuses on dynamic pricing decision with a static reference price in revenue management situations. Firstly, it defines the concept of multiplicative reference effect, and describes the characteristics of the reference effect and the demand function with multiplicative reference effect. Secondly, it constructs the optimal control...
The LEO(Low-Earth-Orbit) drag-free satellite provides low-interference test environment for the validation of relativity, detection of gravitational waves and measurement of gravity field, which offset all kinds of disturbances from the space by continuous active control to achieve a state of pure free falling. One of the important researches is to ensure the control accuracy and performance. In this...
The study is based on tourist type and focuses on four common local travel modes to compare tourism utility through analytic hierarchy process (AHP). Local travel unity is decided by both origin and destination, and service quality. Tourists can be divided into business and leisure types according to significant difference in time and destination plan. And it turns out that business and leisure tourists...
Two camps of file systems exist: parallel file systems designed for conventional high performance computing (HPC) and distributed file systems designed for newly emerged data-intensive applications. Addressing the big data challenge requires an approach that utilizes both high performance computing and data-intensive computing power. Thus, HPC applications may need to interact with distributed file...
If the anti-slip regulation function can be attached to the conventional automatic transmission control system, the vehicle's tractive ability, steering capability and driving stability on the low friction road will all be improved greatly with very low additional hardware costs. Therefore, the extension of anti-slip regulation function on the automatic transmission control system has an important...
This paper studies the organizational influences on failure rates. The failure rate model in MIL-HDBK-217F is extended to include organizational factors, and a Bayesian approach is proposed to quantify the organizational influences. In contrast to most explicit organizational models, this paper focuses on extracting information from failure rate data. The proposed Bayesian approach, however, can be...
EIMS is a stable and safe communication system. It integrates the communication of citizen patrols and police units. When unexpected emergency happens, the system can enhance the citizen patrols' communications capabilities, decrease the time in communication and response, and reduce the loss of life and property. There are five citizen patrols implemented EIMS in northern Taiwan. They have enhanced...
This paper presents our works to tackle three key problems in modern research of traditional Chinese medicines. Based on a dataset of 100 medicines (each with 60 major ingredients), we evaluate various data mining approaches in order to unveil the underlying associations between these chemical ingredients and the pharmic qualities of the medicines. Based on our experiements, we conclude that these...
The computing paradigm of "HPC in the Cloud" has gained a surging interest in recent years, due to its merits of cost-efficiency, flexibility, and scalability. Cloud is designed on top of distributed file systems such as Google file system (GFS). The capability of running HPC applications on top of data-intensive file systems is a critical catalyst in promoting Clouds for HPC. However, the...
The MapReduce programming paradigm is gaining more and more popularity recently due to its merits of ease of programming, data distribution and fault tolerance. The low barrier of adoption of MapReduce makes it a promising framework for non-dedicated distributed computing environments. However, the variability of hosts resources and availability could substantially degrade the performance of MapReduce...
Functional decomposition plays an important part in the conceptual design. However, the existing functional decomposition methods for existing products have either a limitation of application scope or can not provide sufficiently comprehensive information. For these, an improved functional decomposition method based on function analysis system technique (called FAST) and the method of removal and...
Check pointing is widely used in technical computing. However, the overhead of check pointing is a subject of increasing in concern in recent years, especially for large-scale parallel computer systems. In these systems, check pointing generates a huge number of concurrent I/O writes. The burst of writes plus the worsening I/O-wall problem often leads to network and I/O congestion, and makes the overall...
Parallel file systems are widely used for providing a high degree of I/O parallelism to mask the gap between I/O and memory speed. However, peak I/O performance is rarely attained due to complex data access patterns of applications. Based on the observation that the I/O performance of small requests is often limited by the request service rate, and the performance of large requests is limited by I/O...
