Research of Informatization Demands of New Countryside in Poyang Lake Ecological Economic Zone and Related Countermeasures

[Objective] The aim was to survey and analyze informatization demand in new countryside in Poyang Lake Ecological Economic Zone and to propose counter- measures, [Method] A questionnaire was made among farmers on informatization de- mands in different regions in Poyang Lake Ecological Economic Zone and the re- sults were analyzed to propose countermeasures promoting informatization. [Result] With strengthening of information awareness, information demands in rural areas in Poyang Lake Ecological Economic Zone change as follows： Information demand car- rier changes from traditional media to modern media; demand on information content changes from one-way to diversified one; demand of information service changes from one-way transmission to interaction and exchange. However, some problems still exist in informatization process, such as poor infrastructure, dispersed information resources, higher information expense and shortage of information-based talents. Hence, the countermeasures were proposed, as follows： Rational security systems should be established; financing should be as diversified as possible; informatization infrastructure should be reinforced; agricultural economic information and informatiza- tion service system should be established. [Conclusion] The research lays foundation for construction of informatization in new countryside in Poyang Lake Ecological Economic Zone.

Investigation of Adaptive Multi-Rate Link Adaptation of 3G System

In term of the features of 3G system, a novel AMR link adaptation strategy for 3G system is proposed. The impacts of AMR codec modes and power control on traffic quality of service are taken into account in the strategy at the same time. By synthetically comparing the signal-to-interference ratio value with the switching threshold and comparing the transmission power with its threshold, radio resource management can always keep each link on its proper codec mode with the corresponding optimal power level to achieve both robust speech quality and link capacity enhancement. Based on the WCDMA FDD uplink link-level simulation platform, AMR link adaptation platform is constructed. Simulation results show that the algorithm can track the fast change of channel conditions and select the most robust codec mode, thus the synthetic speech quality of AMR is better than that of signal mode during a wide range of channel conditions. The result will provide a reference strategy for AMR link adaptation of 3G system.

Reliability and validity of the Chinese version of the Head and Neck Information Needs Questionnaire for patients with head and neck cancer and their caregivers

Objectives:This study aimed to assess the reliability and validity of the Chinese version of the Head and Neck Information Needs Questionnaire(HaNiQ).Methods:The HaNiQ was translated into a Chinese version using internationally recognized forwardand back-translation procedures.The reliability and validity of the HaNiQ were measured using Cronbach’s a coefficient,split-half reliability,exploratory factor analysis,and Pearson correlation analysis.Results:A total of 207 patients in different head and neck cancer(HNC)stages and 174 caregivers completed the Chinese version of the HaNiQ.Internal consistencies varied between good and very well(Cronbach’s α coefficient 0.74-0.90);the split-half coefficient and the content validity index(CVI)of the questionnaire were 83.5%and 83.33%,respectively.The cumulative contribution rates of the 5 subscales in patients with HNCand their caregivers were 62.41%and 61.19%,respectively.However,there are some differences between the Chinese questionnaire for caregiver and the original questionnaire regarding the attribution of items.Items 22,23,and 27 in the Psychosocial subscale of the English version were assigned to the Survivorship subscale in the Chinese version for caregivers.Conclusions:The results demonstrated that the Chinese version of the HaNiQ is a reliable and valid instrument for measuring the information needs of patients with HNC and that of their caregivers.Though the structure of the Chinese versionwas different from the English version for caregivers of HNC patients,the Chinese version of the HaNiQ appears to be reliable and would benefit from further testing.

A signal-summing programmable gain amplifier employing binary-weighted switching and constant-g--_m bias

A novel programmable gain amplifier（ PGA） based on a signal-summing topology is proposed. Different from conventional signal-summing variable gain amplifiers（ VGA）,a binary-weighted switching technique is employed to vary the current-steering transistors＇ aspect ratio to change their transconductance, and hence, an accurate gain step size of 6dB is achieved. The constant-g_m biasing technique and the matching of the transistors and resistors ensures that the gain of the proposed topology is independent of the variation of process, voltage and temperature（ PVT）. P-well NMOS（ Nmetal oxide semiconductor） transistors are utilized to eliminate the influence of back-gate effect which will induce gain error.The source-degeneration technique ensures good linearity performance at a low gain. The proposed PGA is fabricated in a0.18 μm CMOS（ complementary metal oxide semiconductor）process. The measurement results show a variable gain ranging from 0 to24 dB with a step size of 6 dB and a maximum gain error of 0. 3dB. A constant 3dB bandwidth of 210 MHz is achieved at different gain settings. The measured output 3rd intercept point（OIP3） and minimum noise figure（ NF） are20. 9 dBm and 11.1 dB, respectively. The whole PGA has a compact layout of 0.068 mm^2. The total power consumption is4. 8 mW under a 1. 8 V supply voltage.

On the Relationship between China and the International Energy Agency

As China needs to play a more active role in global energy governance, it must create a diversified, multi-level system to enhance energy security and to alleviate environmental pressures. A China-IEA bilateral relationship exists under an Association Initiative, but a stronger bond is needed. Though it is not an IEA member, China's massive energy needs makes it sensible that the two sides overcome existing obstacles that include OECD membership, statistical information issues and energy autonomy. In this regard an "IEA+China" might be a feasible model.

Polynomial rooting based frequency offset estimation for MIMO OFDM systems

Based on the frequency domain training sequences, the polynomial-based carrier frequency offset （CFO） estimation in multiple-input multiple-output （ MIMO ） orthogonal frequency division multiplexing （ OFDM ） systems is extensively investigated. By designing the training sequences to meet certain conditions and exploiting the Hermitian and real symmetric properties of the corresponding matrices, it is found that the roots of the polynomials corresponding to the cost functions are pairwise and that both meger CFO and fractional CFO can be estimated by the direct polynomial rooting approach. By analyzing the polynomials corresponding to the cost functions and their derivatives, it is shown that they have a common polynomial factor and the former can be expressed in a quadratic form of the common polynomial factor. Analytical results further reveal that the derivative polynomial rooting approach is equivalent to the direct one in estimation at the same signal-to-noise ratio（SNR） value and that the latter is superior to the former in complexity. Simulation results agree well with analytical results.

COOPERATIVE ARQ PROTOCOL FOR CORRELATED WIRELESS CHANNELS

A novel Automatic repeat ReQuest (ARQ) protocol called cooperative ARQ is presented in this let-ter, where a relay terminal is requested to retransmit an erroneously received packet, instead of the source ter-minal. The data link layer Packet Error Rate (PER) performance of cooperative ARQ is derived in correlated wireless channel. The results show that even though the relay-destination channel is worse than the source-destination channel, the new protocol outperforms the traditional one as long as the average SNR of the relay-destination channel is better than a certain threshold. It is also demonstrated that a second order diversity gain can be achieved with the cooperative ARQ protocol.

Joint Optimization of Channel Allocation,Link Assignment and Power Control for Device-to-Device Communication Underlaying Cellular Network

Device-to-Device(D2D) communication has been proposed to facilitate cellular network with system capacity(SC) and quality of service(QoS).We consider the design of link assignment(LA),channel allocation(CA)and power control(PC) in D2D-aided content delivery scenario for both user fairness(UF)and system throughput(ST) under QoS requirement.Due to the complexity of the problem,we decompose it into two components:CA is formulated from graph perspective to mitigate severe co-channel interference,which turns out to be the Max K-cut problem;LA and PC are jointly optimized to utilize the gain achieved from CA for supreme performance,and specifically,genetic algorithm(GA) is adopted to optimize LA,but when deriving the fitness of each chromosome,PC optimization will be involved.Thanks to numerical results,we elucidate the efficacy of our scheme.

RESEARCH ON VALUE OF INFORMATION SHARING IN ONE SUPPLIER-MULTIPLE RETAILER SUPPLY CHAIN

Prior research has generally focused on models involving a single or multiple retailers with independent demands. The value of demand information sharing is analyzed in a two-level supply chain involving one supplier-multiple retailer model in which retailer demands may be correlated. Each member in the supply chain forecasts its demand using an AR (1) demand process. Two conditions of the information sharing are considered (1) Without the information sharing, the retailers only communicate their orders to the supplier. (2) With the information sharing, retailers communicate their orders and forecasting models to the supplier. Analyses showthat the reductions of supplier's average inventory and average costs are substantial with the information sharing. However, the retailers donot get direct benefit from the information sharing. The retailers may ask the supplier to reduce the replenishment leadtime, so that the retailers will obtain substantial cost savings and inventory reduction. Both partners may obtain benefits when information sharing and leadtime reduction are implemented together.

Modeling TCP performance with proxy and ARQ

TCP/IP is a next generation key technology in the wireless communication network where the different characteristics of wireless and wired links result in performance degradation. We can use the proxy and automatic repeat request (ARQ) schemes to deal with this problem. In this work, we investigate the TCP performance over proxy and ARQ in the wireless network. Our analysis results showed that using the proxy can result in lower transfer latency and higher throughput and that ARQ can decrease the loss rate of wireless link and improve the performance with little additional latency. The analytical results were validated against simulations using the NS-2 with some more realistic parameters.

Video coding bit allocation algorithm over wireless transmission channel

For two-way video communications over wireless channels using the automatic repeat request (ARQ) retransmission scheme, TMN8 rate control scheme is not effective in minimizing the number of frames skipped and cannot guarantee video quality during the retransmissions of error packets. This paper presents a joint source channel bit allocation scheme that allocates target bits according to encoder buffer fullness and estimation of channel condition by retransmission information. The results obtained from implementing our scheme in H.263+coder over wireless channel model show that our proposed scheme encodes the video sequences with lower and steadier buffer delay, fewer frames skipped and higher average PSNR compared to TMN8.

Translating Chinese Public Signs into English from Context of the Adaptation Theory

Translation of public signs is related to the image of a city. It has aroused more and more concerns in recent years, for translations of these public signs are often totally wrong or inappropriate. Although many translators have pointed out all kind of mistakes, there is no guiding theory in translating public signs. According to the adaptation theory by Jef. Verschuren, the use of language is just to make continuous choices in order to adapt to the needs of communications. This scientific new research angle can explain and guide translation of public signs. The argument of this paper is how to translate Chinese public signs into English from different context. And it will be analyzed from three different ways： linguistic, communicative, dynamic dimensions.
