Integration of Multipath TCP and Network Coding for Satellite Networks

This paper investigates how to support reliable satellite communication using TCP assuming that multiple satellite links are available and Multipath-TCP (MPTCP) as well as Software-Defined Networking (SDN) can be used to map sub-flows to different satellite links. To improve redundancy we propose integrating Network Coding into MPTCP. The paper discusses in detail the related work on MPTCP, SDN, Network Coding, and satellite communication, in particular certain combinations. We present a possible approach to integrate these for our target satellite communication scenario and discuss various design options.
Optical Activity of an Asymmetric Substance

This paper reported the investigation on the property of optical activity from three different isomers of L-, Dand DL--alanine (CH3CHNH2CO2H), a proposed radiation dosimetric material. The aim was to confirm the impact of attachment of -carbon atom of the systems to the four different groups, that is, the -carbon or methyl group, H-group, CO2H-group and NH2-group, to their response to any incoming plane-polarized light. Optical activity of a substance is a measure of the ability of a substance to rotate a plane of polarization, if solution of the substance is placed in the path of plane-polarized light. A polarimeter of Perkin-Elmer Model 141 with a Sodium lamp of 584-nm wavelength (D-line) and equipped with a digital counter was occupied in this work to measure the number of degrees of rotation of plane-polarized light at room temperature due to 8.3% concentration of each L-, D- and DL--alanine solutions. It was obtained that molecules of L-isomer rotate the counter of the polarimeter clockwise, from the observer’s point a view. While the molecules of D-isomer rotate the counter anti clockwise, at the similar amount of rotation. These results confirm the asymmetric structure belong to the -alanine system. Molecules of DL-isomer, however, do not rotate the counter at all. The existence of similar number of the D- and L-molecules in the DL-solution is the cause.
A polymorphism in the GALNT 2 gene and ovarian cancer risk in four population based case-control studies

Recent epidemiologic evidence supports a role for MUC1 in ovarian carcinogenesis; therefore, we hypothesized that common genetic variation in the genes responsible for glycosylation of MUC1 may influence ovarian cancer risk. In a genome-wide association study of ovarian cancer, we observed an association between a non-synonymous SNP (rs2271077) in the UDP-N-acetyl-alpha-d-galactosamine: polypeptide N-acetylgalactosainyltransferase 2 (GALNT2) gene and ovarian cancer risk (p=0.005). We sought to validate the association in four population based ovarian cancer case-control studies collaborating through the Ovarian Cancer Association Consortium. Although rs2271077 was associated with a significantly increased risk (Odds Ratio (OR) = 1.37, 95% Confidence Interval (CI) =1.06-1.77) in one study with 961 cases and 922 controls, we observed no association in the remaining three studies including 1452 cases and 1954 controls (OR=0.83, 95% CI= 0.66-1.04). Therefore, there appears to be no strong evidence of association between GALNT2 SNP rs2271077 and ovarian cancer risk.
SENSITIVITY OF HOT-CATHODE IONIZATION VACUUM GAGES IN SEVERAL GASES

Four hot-cathode ionization vacuum gages were calibrated in 12 gases. The relative sensitivities of these gages were compared to several gas properties. Ionization cross section was the physical property which correlated best with gage sensitivity. The effects of gage accelerating voltage and ionization-cross-section energy level were analyzed. Recommendations for predicting gage sensitivity according to gage type were made.
Hepatic Effects in Hyperlipidemic Patients

Background. This study was conducted to demonstrate the relationship between nonalcoholic fatty liver and hyperlipidemia. Methods. We retrospectively analyzed patients receiving periodic health checkups at China Medical College Hospital from January to December, 2000. Subjects with a medical history of diabetes mellitus or alcohol abuse were excluded. Totally, 186 patients (men: 60.8%; women: 39.2%) were included in this study. The mean age was 44.5 years old with a standard deviation of 12.5 years (age range,18-78). Fatty liver was diagnosed by sonography. The primary factors studied were total cholesterol, triglyceride, low density lipoprotein cholesterol and high density lipoprotein cholesterol. The t test, Chi-square and multivariate logistic regression were used for statistical analysis. Results. The proportion of the subjects having nonalcoholic fatty liver was 32.8%. According to univariate analysis, male gender, hypercholesterolemia and hypertriglyceridemia were related to nonalcoholic fatty liver. After controlling for other covariates, multivariate logistic regression analysis showed that the significant factors related to nonalcoholic fatty liver were male gender (odds ratio = 4.0, 95%confidence interval = 1.8-8.8,p＜ 0.001) and hypertriglyceridemia (odds ratio =5.8,95% confidence interval = 1.8 -19.0,p＜ 0.01) Conclusions. A large detailed investigation is needed in the future to reveal the other related factors of nonalcoholic fatty liver.
Infrared spectroscopy of the merger candidate KIC 9832227

Context. It has been predicted that the object KIC 9832227 – a contact binary star – will undergo a merger in 2022.2 ± 0.7. We describe the near-infrared (NIR) spectrum of this object as an impetus to obtain pre-merger data. Aims. We aim to characterise (i) the nature of the individual components of the binary and (ii) the likely circumbinary environment, so that the merger – if and when it occurs – can be interpreted in an informed manner. Methods. We use infrared (IR) spectroscopy in the wavelength range 0.7–2.5 μm, to which we fit model atmospheres to represent the individual stars. We use the binary ephemeris to determine the orbital phase at the time of observation. Results. We find that the IR spectrum is best fitted by a single component with effective temperature 5920 K, log[g] = 4.1, and solar metallicity, consistent with the fact that the system was observed at conjunction. Conclusions. The strength of the IR H lines is consistent with a high value of logg, and the strength of the Ca II triplet indicates the presence of a chromosphere, as might be expected from rapid stellar rotation. The He I absorption we observe likely arises in He excited by coronal activity in a circumstellar envelope, suggesting that the weakness of the Ca II triplet is also likely chromospheric in origin.
Fatty acids and TBA-RS in frozen stored breast meat of chickens fed diets with rapeseed oil supplemented with fish oil and vitamin

640 Cobb chickens 22 days old were assigned to 16 groups and fed four types of diet contained rapeseed oil (50, 47, 45 or 42 g · kg ) and stabilized fish oil (0, 3, 5 or 8 g · kg ), respectively and supplemented with α-tocopheryl acetate (0, 40, 150 or 300 mg · kg ). At 43 day of age chickens were killed and breast meat was prepared, packed and frozen (-20 C). Samples were stored during 6 month and then analyzed for fatty acids composition and for TBA-RS and vitamin E content. Fish oil (FO) incorporated at level of 5-8 g · kg –1 to the diet with rapeseed oil significantly (P<0.01) elevated from 75 g to 85 g · kg –1 the content of stearic acid (C 18) and from 4,9 g to 7 g · kg –1 of eicosapentaenoic acid (C 20:5, n-3 ) and advantageously lowered from 5.5 to 5.1 the PUFA n-6 : n-3 ratio in stored breast meat lipids. FO at dietary level of 8 g · kg –1 decreased from 413 to 394 g · kg –1 PUFA and from 344 to 322 g · kg –1 PUFA n-6 content, increased from 235 g to 250 g· kg –1 SFA and lowered from 1.8 to 1.6 the PUFA : SFA ratio in lipids (P<0.05). Vitamin E supplementation (150-300 mg α-tocopheryl acetate· kg ) of diet enlarged from 2.4 to 12.35 mg· kg –1 (P<0.001) the content of α-tocopherol and lowered TBA-RS content in meat from 0.514 to 0.382 · kg .

The actions taken to achieve service improvements were analysed through a lens of team learning. Findings – Team learning is an appropriate frame of reference for analysing actions designed to bring about change and improvement. Seven distinct team learning activities are defined. Research limitations/implications – The implication of the study is that it is useful to apply a theoretical framework of organisational learning to service improvements undertaken by work teams. The study indicates learning processes that were important elements in these changes. The study limitation was that information was gathered mainly from the leaders of ea.
Application of Near Infrared Spectroscopy in Rapid Determination of Adenosine and Polysaccharide in Cordyceps Militaris

The adenosine and polysaccharide contents in cordyceps militaris were analyzed with near infrared spectroscopy (NIRS) by establishing models with partial least square (PLS). Varies pretreating spectra methods were used for conversion of NIRS in order to remove the noise in the spectra. The pretreated spectra were applied to develop PLS quantitative analysis models respectively. Each model was optimized by selecting the most suitable amount of factors. The optimal model was selected depend on the root mean squares of calibration sets calculate by cross-validation (RMSECV) and the root mean squares of predicted sets (RMSEP). The RMSECV values of the optimum PLS models for determination adenosine and polysaccharide contents were 0.7592 and 0.0093 respectively. Using this optimum model for determination of adenosine and polysaccharide contents in cordyceps militaris mycelium powder, The RMSEP values were 0.6720 and 0.0083 respectively.
Interfacial surface investigation of super-critical water gasification of corn cob

Super-critical water gasification of biomass is a promising technology for hydrogen production. In order to achieve high hydrogen yield and complete gasification, the operating parameters were investigated and the solid residual was analyzed to study the reaction bottleneck by Fourier transform infrared spectroscopy and scanning electron microscopy. The experimental results showed that most organic functional groups in corn cob were consumed by super-critical water above 500 °C, however, the aromatic substance and cyclic ketone were remained. The K2CO3 has the best catalytic effect due to the formation of pore structure in the residual particle surface. The carbon gasification efficiency of 97.97% and the hydrogen yield was 50.28 mol/kg.
Effect of sample extraction, preparation methods on HPLC quantification of plumbagin in in vivo and in vitro plant parts of Plumbago zeylanica L.

Plumbagin is an important therapeutic compound of Plumbago zeylanica L. , the commercial demand of this compound warrants optimizing a suitable method to isolate plumbagin in large scale. The present study was undertaken to obtain the maximum recovery of plumbagin content by employing different extraction methods viz., ultra-assisted extraction (UAE), maceration extraction (ME), soxhlet extraction (SE), serial soxhlet extraction (SSE), and serial maceration extraction (SME) from plant parts of P. zeylanica. Plumbagin content of two different sources such as field grown and hardened in vitro regenerated plants were quantified using reversed-phase high-performance liquid chromatography (RP-HPLC). For in vitro cultures, 6-benzylaminopurine (BAP) and Kinetin (KIN) were used for multiple shoot induction from nodal segments of P. zeylanica. Maximum percentage of shoot induction was obtained on MS medium fortified with BAP (6.66 µM) from nodal segments exposed for 6 weeks. Further multiple shoot proliferation and elongation was achieved in MS medium with a combination of BAP (6.66 µM) and KIN (4.44 µM), with the maximum number of shoots (47.3±0.06) and shoot length (2.0±0.06 cm) per explant after 6 weeks of culture. The optimum root induction was observed on MS medium supplemented with 1.23-µM indole-3 butyric acid (IBA) which produced 10.02±0.2 mean roots with 6.2±0. 8 cm root length. Among the extraction methods, the SME method yielded maximum recovery (99.5%) of plumbagin as compared to others. In vitro leaf extract yielded high content of plumbagin (152.02 mg/g-1 DW) as compared to other plant parts (root 115.41 mg/g-1 dry weight; stem 98.02 mg/g-1 dry weight) whereas in vivo leaf, stem and root samples yielded 96.7, 38.59, and 86.35 mg/g DW of plumbagin, respectively. The present observation suggests that the SME was more efficient for obtaining the maximum recovery of plumbagin and it was confirmed with HPLC quantification. Among the field grown and in vitro regenerated plants, the in vitro culture shows more accumulation of plumbagin and is found suitable for commercial extraction. Key words: Micropropagation, cytokinin, serial maceration extraction (SME), optimization, methanol, quantification.
Elastic image registration with exact mass preservation

We establish a new framework for image registration, which is based on linear elasticity and optimal mass transportation theory. We combine these two arguments in order to obtain a PDE constrained optimization problem that is analytically investigated and further discretized with the finite difference method and solved by an inexact SQP algorithm. This requires to solve in each step a large sparse linear system, which has a saddle point form. Motivated by stability arguments we use a fully staggered grid for the discretization of the displacement vector field. Artificial and real world examples are presented to underline the numerical robustness of the method.
2 Winners and Losers : German Equity Mutual Funds 1

We investigate the performance of winners and losers for German equity mutual funds (1990-2009) using empirical order statistics. When using gross returns and the Fama-French three factor (3F) model, the number of statistically significant positive-alpha funds is zero but increases markedly when market timing variables are added. However, when using a “total performance” measure (which incorporates both alpha and the contribution of market timing), the number of statistically significant winner funds falls to zero. The latter is consistent with bias in estimated alphas in the presence of market timing. We also find that many poorly performing funds are unskilled rather than unlucky. Keyword : Mutual fund performance, order statistics.

Frequent patterns discovery and analysis granularity recognition for Shanghai Composite Index sequence

The Shanghai Composite Index is a typical time series, and reflects the stock market variations. In this paper, a method is proposed for mining frequent patterns from the Shanghai Composite Index using the agglomerative hierarchical clustering algorithm based on DTW. For reflecting the nature of research question and reducing the computational complexity, the best time granularity is found by effective evaluation based on the clustering results.
Induced-valued intuitionistic fuzzy hybrid Choquet integral operators and their application in decision making

Based on the Choquet integral and the generalized Shapley function, two new induced -valued intuitionistic fuzzy hybrid aggregation operators are defined, which are named as the induced generalized Shapley -valued intuitionistic fuzzy hybrid Choquet arithmetical averaging (IGS-IVIFHCAA) operator and the induced generalized Shapley -valued intuitionistic fuzzy hybrid Choquet geometric mean (IGSIVIFHCGM) operator. These operators do not only globally consider the importance of elements and their ordered positions, but also overall reflect the correlations among them and their ordered positions. Meantime, some important cases are examined, and some desirable properties are studied. Furthermore, if the information about the weighting vectors is incompletely known, the models for the optimal fuzzy measures on attribute set and ordered set are established, respectively. Moreover, an approach to multi-attribute decision making under -valued intuitionistic fuzzy environment is developed. Finally, a numerical example is provided to illustrate the proposed procedure.
A novel multipath disjoint routing to support ad hoc wireless sensor networks

Ad hoc wireless sensor networks have the potential to become a major component of the information technology space due to the characteristics of sensor devices links and communications. The existing protocols for the traditional ad hoc networks affect the performance of the system in wireless sensor network. In this paper, multipath disjoint (MPD) routing algorithm is proposed. We compare MPD with two on-demand protocols such as DSR and AODK The simulation results show that MPD improves the packet delivery ratio and throughput, saves power and reduces delay. As a result MPD releases the network congestion quite well. The system does not bring breakdown because of the routing failure
A SQUID series array dc current sensor

Superconducting quantum interference device (SQUID) sensors are used to sense changes in various physical quantities, which can be transformed into changes in the magnetic flux threading the SQUID loop. We have developed a novel SQUID array dc current sensor. The device is based on a series array of identical dc SQUIDs. An input signal current to be measured is coupled tightly but non-uniformly to the SQUID array elements. The input signal coupling to the individual array elements is chosen such that a single-valued, non-periodic overall voltage response is obtained. Flux offsets in the individual SQUIDs which would compromise the sensor voltage response are avoided or can be compensated. We present simulations and experimental results on the SQUID Array for Dc (SQUAD) current sensor current sensor performance. A dc current resolution of <1 nA in a measurement bandwidth of 0–25 Hz is achieved for an input inductance of LIn<3 nH.
Robovacs in the domestic environment:measuring physiology to identify emotions underlying real-world human-robot interaction

During the last decade the development of personal service robots has been thriving. In addition to the technical requirements, attention has to be paid to the human-centered viewpoint, which concentrates on the interaction between humans and robots (Dautenhahn, 2007). Accordingly, within the context of Human-Robot Interaction (HRI) this study investigates user’s emotional response toward vacuum robots (robovacs) by employing physiological (EDA), quantitative and qualitative measurements. The study included observing two distinct robovacs in the living rooms of the participants (n=16). The results indicated a higher physiological reaction during robot interaction than during non-activity. Instead of finding a significant difference in EDA reaction toward the robovacs, a significant gender difference was found. Though the amount of collisions differed significantly, no relation between collisions and arousal could be established. In general Samsung vacuum cleaner, Navibot, received a more positive evaluation than iRobot’s Roomba. As this study is a means to indicate first experimental insights, future research could conduct a longitudinal field-study where the individual reactions toward the robovacs could be investigated in more detail.
A Reinforcement Learning Algorithm Based on Minimum State Method and Average Reward

Reinforcement learning is learning what to do--how to map situations to actions--so as to maximize a numerical reward signal. In allusion to the problem that Q-Learning, which uses discount reward as the evaluation criterion, cannot show the affect of the action to the next situation, the paper puts forward AR-Q-Learning based on the average reward and Q-Learning. In allusion to the Curse Of Dimensionality, which means that the computational requirements grow exponentially with the number of state variables, the paper puts forward Minimum State Method. AR-Q-Learning and Minimum State Method are used in the reinforcement learning of Blocks World, and the result of the experiment shows that the method has the characteristic of after effect and converge more faster than Q-Learning, and at the same time, solve the Curse Of Dimensionality in Blocks World in a certain extent.
An Isophote-Oriented Image Interpolation Method

This paper presents an isophote-oriented image interpolation method that attempts to produce smooth reconstructions of the image¿s level curves while still maintaining image fidelity. The proposed method employs an interpolation kernel that is obtained by looking for the explicit solution of a nonlinear PDE (partial differential equation). The PDE preserve the local continuation of isophotes (curves of constant intensity). By doing so, the curvature of the interpolated isophotes is reduced, and, thus, zigzagging artifacts are largely suppressed. Moreover, the interpolation techniques can preserve edge sharpness. In addition, the proposed methods can be used irrespective of the magnification factor (MF) and easily implemented due to their simple structure. Experiments show that images interpolated using the proposed method are both visually and quantitatively improved.
Crack initiation behavior of notched specimens on heat resistant steel under service type loading at high temperature

Cracks at notches deserve special consideration in the design of steam turbine components. This work is addressed to investigate the crack initiation behavior a 10%Cr rotor steel with the help of notched specimens under service-type loading. A significant drifting down of the peak-values of axial deformation under constant amplitude load was observed. Crack initiation was evaluated with the help of the relationship between irreversible deformation energy and cycle number. Further, metallographic examinations were employed to characterize the superposition of creep and fatigue damage mechanisms. Both Neuber-hypothesis and von Mises equivalent strain at notch root were applied for lifetime prediction. Finally, the effectiveness of both methods is validated by comparing with experimental results.
