Lossy-to-Lossless Compression of Hyperspectral Image Using the 3D Set Partitioned Embedded ZeroBlock Coding Algorithm  [PDF]
Ying Hou
Journal of Software Engineering and Applications (JSEA) , 2009, DOI: 10.4236/jsea.2009.22013
Abstract: In this paper, we propose a three-dimensional Set Partitioned Embedded ZeroBlock Coding (3D SPEZBC) lossy-to-lossless compression algorithm for hyperspectral image which is an improved three-dimensional Embedded ZeroBlock Coding (3D EZBC) algorithm. The algorithm adopts the 3D integer wavelet packet transform proposed by Xiong et al. to decorrelate, the set-based partitioning zeroblock coding to process bitplane coding and the con-text-based adaptive arithmetic coding for further entropy coding. The theoretical analysis and experimental results demonstrate that 3D SPEZBC not only provides the same excellent compression performances as 3D EZBC, but also reduces the memory requirement compared with 3D EZBC. For achieving good coding performance, the diverse wave-let filters and unitary scaling factors are compared and evaluated, and the best choices were given. In comparison with several state-of-the-art wavelet coding algorithms, the proposed algorithm provides better compression performance and unsupervised classification accuracy.

Xuezhang Hou
Journal of Applied Mathematics and Physics (JAMP) , 2013, DOI: 10.4236/jamp.2013.15015
Abstract:

An elastic beam system formulated by partial differential equations with initial and boundary conditions is investigated in this paper. An evolution equation corresponding with the beam system is established in an appropriate Hilbert space. The spectral analysis and semigroup generation of the system operator of the beam system are discussed. Finally, a variable structural control is proposed and a significant result that the solution of the system is exponentially stable under a variable structural control with some appropriate conditions is obtained.

Does the Pay Gap in the Top Management Team Incent Enterprise Innovation?—Based on Property Rights and Financing Constraints  [PDF]
Jingru Hou
American Journal of Industrial and Business Management (AJIBM) , 2018, DOI: 10.4236/ajibm.2018.85088
Abstract: Using the patent applications data of listed firms in China from 2005 to 2014, this paper examines how the pay gap in the top management team influences enterprise innovation. The result shows that the number of patent applications especially the number of patents for invention increases significantly when the pay gap enlarges. It means the enlargement of the pay gap in the top management team could incent executives to make innovation decisions, to promote outputs of high-quality patents for invention. Finally the quality of enterprise innovation has been improved. Especially, the incentive effect of the pay gap in the top management team is more significant in private enterprises and enterprises with strong financing constraints. Therefore, enterprises in these two groups have better innovation behaviors.

Shubei Li,Dong Zhang,Lan Yang,Yujie Li,Xiaoxin Zhu,Eva Kmoní?ková,Zdeněk Zídek
Journal of Chemistry , 2013, DOI: 10.1155/2013/452610
Abstract: A simple and accurate HPLC-UV method was developed for the simultaneous quantitative analysis of main stilbenes and flavones in different parts (fronds, rhizomes, and frond bases) of M. struthiopteris. The chromatographic separation was performed on a Kromasil C18 column (4.6?mm?×?250?mm, 5?μm) with the mobile phase of MeOH-H2O (including 0.1% phosphoric acid) using a gradient elution at the flow rate of 1.0?mL?min?1 and UV detection at 295?nm. The method was validated by specificity, linearity, accuracy (recovery), and precision tests (repeatability, intra- and interday). For all the six compounds, the linear regression coefficients ranged from 0.9958 to 0.9998 within the test ranges; intra- and interday precisions were 2% and the mean recoveries ranged from 98.09 to 103.56%. The amount of these compounds in the frond bases was almost the same as in the rhizomes but much higher than that in the fronds. The results indicate that the HPLC method developed was appropriate for the analysis of the six compounds in different parts (fronds, rhizomes, and frond bases) of M. struthiopteris. 1. Introduction Matteuccia struthiopteris (L.) Todaro (ostrich fern), belonging to the family Onocleaceae, is an edible and medicinal fern widely distributed in the temperate regions of the northern hemisphere. The tightly wound immature fronds, called fiddleheads, are used as a cooked vegetable and the young shoots can also be eaten raw in salad. The rhizomes and frond bases of M. struthiopteris have been used as a traditional chinese medicine (TCM) for the treatment of pinworms, influenza, dysentery hematochezia, and uterine hemorrhage for thousands of years. The pharmacological activities of M. struthiopteris include antivirus, antiparasite, and eliminating bacterium [1, 2]. Several C-methyl flavanone derivatives from M. orientalis showed a very strong hypoglycemic effect in streptozotocin (STZ) induced diabetic rats [3, 4]. A series of flavonoids, stilbenes, and phenolics have been previously identified from M. struthiopteris [5–8], which were very similar to that from M. orientalis [3, 4]. In searching for bioactive components of M. struthiopteris, six main compounds (Figure 1) including three C-methyl flavones: demethoxymatteucinol (1), matteucinol (2), and matteuorien (3) and three stilbenes: pinosylvin (4), pinosylvin 3-O- -D-glucopyranoside (5), and 5- -D-glucosyloxy-3-hydroxy-l-trans-stilbene-2-carboxylic acid (6) were separated and identified. Matteucinol could inhibit rat lens aldose reductase [9] and scavenging hydroxyl radical [10]. Pinosylvin was reported to
Interaction between Dutch Soccer Teams and Fans: A Mathematical Analysis through Cooperative Game Theory  [PDF]
Dongshuang Hou, Theo Driessen
Applied Mathematics (AM) , 2012, DOI: 10.4236/am.2012.31014
Abstract: Inspired by the first lustrum of the Club Positioning Matrix (CPM) for professional Dutch soccer teams, we model the interaction between soccer teams and their potential fans as a cooperative cost game based on the annual voluntary sponsorships of fans in order to validate their fan registration in a central database. We introduce a natural cost allocation to the soccer teams, based in a natural manner on the sponsorships of fans. The game theoretic approach is twofold. On the one hand, an appropriate cost game called “fan data cost game” is developed and on the other, it is shown that the former natural cost allocation agrees with the solution concept called “nucleolus” of the fan data cost game.

Jiangping Wan, Jiajun Hou
Journal of Software Engineering and Applications (JSEA) , 2012, DOI: 10.4236/jsea.2012.53022
Abstract: The possible risk factors during SAP Business One implementation were studied with depth interview. The results are then adjusted by experts. 20 categories of risk factors that are totally 49 factors were found. Based on the risk factors during the SAP Business One implementation, questionnaire was used to study the key risk factors of SAP Business One implementation. Results illustrate ten key risk factors, these are risk of senior managers leadership, risk of project management, risk of process improvement, risk of implementation team organization, risk of process analysis, risk of based data, risk of personnel coordination, risk of change management, risk of secondary development, and risk of data import. Focus on the key risks of SAP Business One implementation, the interpretative structural modeling approach is used to study the relationship between these factors and establish a seven-level hierarchical structure. The study illustrates that the structure is olive-like, in which the risk of data import is on the top, and the risk of senior managers is on the bottom. They are the most important risk factors.

Ning Hou, Hui Tang
Pharmacology & Pharmacy (PP) , 2014, DOI: 10.4236/pp.2014.54049
Abstract:

Background: Medication errors are a common problem in Chinese hospital, with potentially harmful consequences for patients. The objective of this study was to analyze the cause of typical serious medication errors in some first-class provincial hospital to prevent medication error and improve rational use of drug and ensure patients administration security. Medication errors were collected between September 1, 2012 and August 31, 2013. 332 cases’ medication errors were categorized as harmful or not according to NCC MERP’s Index and other indexes such as type of error and causes of error. We focus on analyzing the 3 serious cases (0.9%, n = 3) among the all MEs that may have contributed to or resulted in temporary harm to the patient and required intervention, including the process and the cause and the background of the errors. The case analysis reminds us to pay more attention to prevent medication errors. The preventive medication error’s measures are explored through the analysis of the causes, such as forcing functions and constraints, automation and standardization, double-checking systems, rules and policies, information and more careful working. Conclusion: This analytical study demonstrates that medication error is an objective existent in hospital. It is especially important to ensure patient medication safety for reporting and analyzing medication error in order to explore measures preventing medication error.

Acoustic Polaron in Free-Standing Slabs  [PDF]
Junhua Hou, Guangming Si
World Journal of Condensed Matter Physics (WJCMP) , 2014, DOI: 10.4236/wjcmp.2014.44025
Abstract: The ground-state energy and its derivate of the acoustic polaron in free-standing slab are calculated by using the Huybrechts-like variational approach. The criteria for presence of the selftrapping transition of the acoustic polaron in free-standing slabs are determined qualitatively. The critical coupling constant for the discontinuous transition from a quasi-free state to a trapped state of the acoustic polaron in free-standing slabs tends to shift toward the weaker electronphonon coupling with the increasing cutoff wave-vector. Detailed numerical results confirm that the self-trapping transition of holes is expected to occur in the free-standing slabs of wide-bandgap semi-conductors.
