“Kunstlehre” and Applied Phenomenology  [PDF]
Wen-Sheng Wang
Open Journal of Philosophy (OJPP) , 2013, DOI: 10.4236/ojpp.2013.32048
Abstract: This article attempts to clarify the ambiguity or double sense of “Kunstlehre” by Husserl and Gadamer, and emphasizes “Kunstlehre” as pure science that originated in Aristotle’s evaluation of theoría, and as fine art, or as the nature or quasi-nature of “as if”, according to Kant’s idea. Aristotle’s concept of phrónesis will be also regarded as a kind of natural “as if”, and considered as “Kunstlehre”. Gadamer’s philosophical hermeneutics makes a high level or deep theoretical reflection on the “Kunst” of understanding. He founds his hermeneutics under phrónesis, which will be discussed in detail. Regarding the application of “Kunstlehre” to a practical research, this article shows a contribution by Hersch, and explains how phrónesis is actualized in a case study by him. In the end, “Kunstslehre” will be pointed out as a process of exercise with time whereby Sensus communis functions as a principle (arché) of Gadamer’s hermeneutics, and makes the process of the formation of phrónesis possible
Sidelobe Suppression in CR-OFDM system by Adding Extended Data Carriers  [PDF]
Tianwei Wen, Yafeng Wang
Communications and Network (CN) , 2013, DOI: 10.4236/cn.2013.53B2060
Abstract: Out-band radiation is a severe problem for Cognitive Radio with OFDM system (CR-OFDM) which is caused by the sidelobe of OFDM signals. Lots of studies have been done on suppressing the sidelobe power and numerous methods have been proposed. In this paper, we propose a novel method to minimize the sidelobe by adding extended data carrier so called EDC to the original data carriers so as to protect primary user (PU) spectrum. Unlike the methods before, the EDCs are deployed within the secondary user (SU) data frequency spectrum to fully use the spectrum. Moreover, we derive the linear least squares problem to get the optimal weighting factors of EDCs to minimize the sidelobe power which is subject to an original data interference constraint. By simulation, we find that EDC is more capable in sidelobe suppression than method of Cancellation Carrier (CC) while EDC has only a small loss in BER performance.

Abstract: By briefly reviewing relevant theories and studies about marketing channel evaluation and directing at the channel characteristics of painting material industry, this paper discusses how enterprises choose competitive marketing channels from the angle of brand building. Studies are carried out from three aspects which are economic efficiency, stability and expansibility of channels, and an evaluation index system of selecting channel members in painting material industry is established. Besides, comprehensive evaluation is conducted for distribution efficiency, transaction cost, cooperative intention, operation capacity, competitive capacity and sustainable development capacity of channels through 18 indexes. Moreover, evaluation model of channel selection in painting material industry is constructed via analytic hierarchy process.

Building Requirements Semantics for Networked Software Interoperability  [PDF]
Bin Wen, Keqing He, Jian Wang
Journal of Software Engineering and Applications (JSEA) , 2010, DOI: 10.4236/jsea.2010.32016
Abstract: Naturally, like the web, integrated software systems in Internet will have to be distributed and heterogeneous. To im-prove the interoperability of services for SAAS, it is crucial to build requirements semantics that will cross the entire lifecycle of services especially on requirements stage. In this paper, a requirements semantics interoperability extend-ing approach called Connecting Ontologies (CO) that will act as semantics information carrier designing to facilitate the requirements identification and services composition is proposed. Semantic measurement of Chinese scenario is explored. By adopting the approach, a series of tools support for transport domain are developed and applied based on CO and DPO (Domain Problem Ontology) to enforce requirements engineering of networked software efficiently.

Zhang An, Bao Yong, Xia Wen, Shuping Wang
iBusiness (IB) , 2013, DOI: 10.4236/ib.2013.53B001
Abstract:

How to improve healthcare system’ efficiency has been highly concerned by Chinese government. The objectives of this paper are to establish production function of medical service and analyze returns to scale; to measure technical efficiency; and to highlight possible policy implications of the results for policy makers. Stochastic Frontier Approach (SFA) is employed in this paper based on data from 2010 China Health Statistical Yearbook. These findings suggest that increasing investment on human resource is a key factor for raising CHS’ efficiency. Operation model and institution will contribute to technology efficiency of CHS.

Virtual Antenna Array Analysis for MIMO Synthetic Aperture Radars
Wen-Qin Wang
International Journal of Antennas and Propagation , 2012, DOI: 10.1155/2012/587276
Abstract: Multiple-input multiple-output (MIMO) synthetic aperture radar (SAR) that employs multiple antennas to transmit orthogonal waveforms and multiple antennas to receive radar echoes is a recently proposed remote sensing concept. It has been shown that MIMO SAR can be used to improve remote sensing system performance. Most of the MIMO SAR research so far focused on signal/data models and corresponding signal processing algorithm. Little work related to MIMO SAR antenna analysis can be found. One of the main advantages of MIMO SAR is that the degrees of freedom can be greatly increased by the concept of virtual antenna array. In this paper, we analyze the virtual antenna array for MIMO SAR high-resolution wide-swath remote sensing applications. The one-dimensional uniform and nonuniform linear antenna arrays are investigated and their application potentials in high-resolution wide-swath remote sensing are introduced. The impacts of nonuniform spatial sampling in the virtual antenna array are analyzed, along with a multichannel filtering-based reconstruction algorithm. Conceptual system and discussions are provided. It is shown that high operation flexibility and reconfigurability can be obtained by utilizing the virtual antenna arrays provided by the MIMO SAR systems, thus enabling a satisfactory remote sensing performance.
A Unique Perspective on Data Coding and Decoding
Wen-Yan Wang
Entropy , 2011, DOI: 10.3390/e13010053
Abstract: The concept of a loss-less data compression coding method is proposed, and a detailed description of each of its steps follows. Using the Calgary Corpus and Wikipedia data as the experimental samples and compared with existing algorithms, like PAQ or PPMstr, the new coding method could not only compress the source data, but also further re-compress the data produced by the other compression algorithms. The final files are smaller, and by comparison with the original compression ratio, at least 1% redundancy could be eliminated. The new method is simple and easy to realize. Its theoretical foundation is currently under study. The corresponding Matlab source code is provided in? the Appendix.
Bed Bug Infestations and Control Practices in China: Implications for Fighting the Global Bed Bug Resurgence
Changlu Wang,Xiujun Wen
Insects , 2011, DOI: 10.3390/insects2020083
Abstract: The bed bug resurgence in North America, Europe, and Australia has elicited interest in investigating the causes of the widespread and increasing infestations and in developing more effective control strategies. In order to extend?global perspectives on bed bug management, we reviewed bed bug literature in China by searching five Chinese language electronic databases. We conducted telephone interviews of staff from 77 Health and Epidemic Prevention Stations in six Chinese cities?in?November 2010. We also conducted telephone interviews of 68 pest control firms in two cities during March 2011. Two species of bed bugs ( Cimex lectularius L. and Cimex hemipterus (F.)) are known to occur in China. These were common urban pests before the early1980s. Nationwide?“Four-Pest Elimination” campaigns (bed bugs being one of the targeted pests) were implemented in China from 1960 to?the early 1980s. These campaigns succeeded in the elimination of?bed bug infestations in most communities. Commonly used bed bug control methods included applications of hot water, sealing of bed bug harborages, physical removal, and applications of residual insecticides (mainly organophosphate sprays or dusts). Although international and domestic travel has increased rapidly in China over the past decade (2000–2010), there?have only been sporadic new infestations reported in recent years. During 1999–2009, all documented bed bug infestations were found in group living facilities (military dormitories, worker dormitories, and prisons), hotels, or trains. One city (Shenzhen city near Hong Kong) experienced significantly higher number of bed bug infestations. This city is characterized by a high concentration of migratory factory workers. Current bed bug control practices include educating residents, washing, reducing clutter, putting items under the hot sun in summer, and applying insecticides (pyrethroids or organophosphates). There have not been any studies or reports on bed bug insecticide resistance.?Difficulties of control were noted in our surveys of dormitories?in which?crowded living, seasonal worker migration, and financial constraints contributed to control failures. This study supports the following conclusions: (1) the bed bug infestation in China dramatically decreased following the campaigns from 1960 to the early 1980s; (2) In our survey of Health and Epidemics Prevention Stations, no bed bug cases were reported in Beijing and Shanghai for the past 12 months, but complaints were reported in Guangzhou, Lanzhou, Urumqi, and Shenzhen; (3) Current bed bug infestations primarily
