A new interface to collect field data which may include text, numeric, GPS, photo, and video to introduce the plant classification in a city park named 18 Peak Mountain at Hsinchu, Taiwan is provided. The new interface is an infrastructure containing Fusion Tables APP which is made by APP Inventor and Google Fusion Tables. The APP can be used to collect photos on site, in addition, GPS will also be...
The goal of Frequent Item set Mining (FIM) is to find the biggest number of frequently used subsets from a big transaction database. In previous studies, using the advantage of multicore computing, the execution time of an Apriori algorithm was sharply decreased: when the size of a data set was more than TBs and a single host had been unable to afford a large number of operations by using a number...
For the realistic demand of data security communications, the paper proposes a new algorithm for encryption/decryption based on the theory of artificial immunization. It is a new method based on the negative selection algorithm and extracts the encryption factor from the plaintext. Encryption factor as a key group is expanded by the way of the m-sequence and generates pseudo-random key sequence that...
Wireless Sensor Networks have been proposed for a multitude of location-dependent application. Solutions in range-free localization are being pursued as a cost-effective alternative to more expensive range-based approaches. In this paper, we present an improved midnormal-based localization algorithm. Compared with its former scheme MBLA, our scheme performs with less compute overhead and improve the...
Problem statement: The next few years, the world towards a high degree of competitiveness of industrial enterprises in the development of business models, competition and cooperation, the flexibility of management changes in a timely manner, on the business and the contractor's use of collaborative software technology to create competitive advantage and set up inter — communication platform to develop...
FR is a steganalysis algorithm based on frequency domain for F5. It has been widely used because of its high-capacity and robustness. In recent years, many scholars have engaged in the field. In this paper, It is proposed for a JPEG information hiding algorithm of resisting F5(JHRF). By embedding secret information into IPEG image by rules, JHRF can deal effectively with abnormal data and get better...
The difficulty for accurate determination of the angles of arrival (AOA) of signals arises from the optimization of likelihood functions of high dimension. Usually, a gradient-based technique is employed to find the optimum of the function. However, this method requires heavy computational work and the differentiability of the likelihood function. This paper presents two gradient-free methods: One...
