An Integrated Saliency Model with Guidance of Eye Movement in Natural Scene Classification
Authors: Du Yu Liang , Yuan Ling Feng , Wan Wei Bing
Published: October 2014

Nature Scene classification is a fundamental problem in image understanding. Human can recognize the scene instantly after only a glance. This is mainly because that our visual attention is easily attracted by the salient objects in scene. And these objects are always representative in the natural scene. It is unclear how humans achieve rapid scene categorization. But this kind of high-level cognitive behavior can be reflected by the eye movement. To identify this ability, we propose a model with the guidance of eye movement. It combines the bag of words (BOW) and spatial pyramid matching (SPM) methods to train and test our model on support vector machine (SVM). The eye movement experiments were employed to validate our model. We found that the subjects could recognize the scenes correctly even if given only a few saliency patches with less than one second. These results suggest that the eye tracking saliency patches play an important role for human scene categorization.

Authors: Chen Yuan Yuan , Geever Luke M. , Higginbotham Clement L. , Devine Declan M.
Published: October 2014

Polylactic acid (PLA) is the most promising material in the biodegradable category. However, brittleness and poor thermal stability restrict its application. To overcome this limitation, PLA may be blended with other biodegradable materials to tailor its properties while maintain biodegradability. In this study a series of blends of PLA and poly (ε-caprolactone) (PCL) with various mass fractions were prepared by solution method and solvent casting. Films of each blend were formed when the solvent evaporated. Subsequently, tensile test samples were punched out of the film for testing and tensile testing, Fourier transform infrared spectrometry (FTIR), Differential scanning Calorimetry (DSC) and contact angle measurements were carried out. Since PCL is a ductile material, the two materials were blended together in an effort to improve the mechanical properties. However, on thermal analysis of the blends, two individual melting peaks were observed in the DSC thermograms. Furthermore, no significant shift in peaks was observed on the FTIR spectra, and clear droplets and boundaries between two components of the blend can be observed in morphology study, all indicated the immiscibility of PLA and PCL. Tensile test showed poor mechanical properties due to the poor adhesion of the two immiscible components of the blend, and the addition of PCL did not influence the wettability of the surface of the blends as there were no significant differences in contact angle measurements.
A New Protocol for Secure Distributed Multiplication of Two Polynomial Shared Values
Authors: Hao Xiang Ning , Wang Xue Min , Deng Li Qiong
Published: October 2014

In view of practical applications, it is a high priority to optimize the efficiency of methods for secure multi-party computations. A classic problem is described as following: there are two secrets, α and β, shared among n players using Shamir (t+1,n)-threshold secret sharing scheme, and how to make their product αβshared among n players using the same way. The protocol of Gennaro, Rabin and Rabin (1998) is a well known and efficient protocol for this purpose. It requires one round of communication and O(n2klog2n+nk2) bit-operations per player, where k is the bit size of the computing field and n is the number of players. In a previous paper (2007), the author presented a modification of this protocol, which reduced its complexity toOn2k+nk2. In 2009, Peter Lory reduced its complexity to On2k. A new protocol is presented in our paper, which reduces this complexity further to Onklog2k. It is better than Gennaro protocol unconditionally. And as to Peter Lory protocol, the reduction is profitable in situation where log2k is smaller than n.

The effects of coagulation concentrations on the physical properties of the RBC membranes were studied and optimized. Features of the RBC of membranes obtained using 0%~40% N,N-Dimethylacetamide (DMAC), such as water absorption percentage, porosity (Pr), ultrafilter rate (UFR), and tensile strength were investigated. The RBC membranes prepared with 40% DMAC solution as coagulant exhibit a smooth surface and a high tensile strength with suitable UFR. RBC showed improved permeabilities for urea and vitamin B12when compared with commercial cellulose membranes.

Authors: Kawai Takahiko , Kuroda Shin-ichi
Published: October 2014

The structure development of poly (L-lactic acid)(PLLA) during the uniaxial drawing was investigated by means of in-situ simultaneous wide-angle X-ray diffraction (WAXD) and small-angle X-ray scattering (SAXS) measurements. When the quenched amorphous film of PLLA was drawn at 77.2 oC, which was well above the glass transition temperature of PLLA, two different crystal structures were formed depending on the strain. The mesophase, which has 103 helix with large amount of packing disorder, was formed at the early stage of drawing, followed by the crystal transformation into α’ form (ε ≥ 1.5). SAXS measurement showed that the kebab formation begins at the stage later than that of meso-α’ transition. It strongly suggests that the transition takes place inside the shish structure. The development of kebab leads to the enhancement of mechanical response, which is found to be the origin of the strain hardening of PLLA.

This paper investigated the macro-mechanical properties of three dimension porous materials consisted of periodically arrayed base units with random pore distribution using homogenization theory. The model of base unit using random numbers was established. A finite element method of homogenization equations was derived for the three dimension periodic structures and was applied to the calculation of the equivalent elastic modulus of porous materials with various porosities.The results shows the equivalent elastic modulus of three dimension porous material has significantly negative correlation with the porosity of material (p < 0.001) and the regression equation is E=(-19.4)ρ+17.6(E=equivalent elastic modulus, ρ=porosity ) when the elastic modulus of the solid matrix is 18 Gpa.

Authors: Yu Huan Yang
Published: October 2014

Polystyrene beads modified with ester group for the separation of n-heptane/toluene have been successfully prepared. The synthesized beads were characterized by fourier transform infrared spectroscopy and thermogravimetric analysis. The effects of ester group on equillibrium swelling ratio and toluene selectivity were studied. The selective factor firstly increases then decreases with the increasing of ester group content. When the content of ester group is 30%, selective factor reaches maximum, the value is 1.62. Polystyrene beads modified with ester group show excellent thermal stability.
Scenario Simulations of Knot-Containing Radiata Boards
Authors: Qu Da Guang , Liu Hua Wu
Published: October 2014

Drying deformation of radiata pine boards results in a great loss of revenue to the wood industry. A computer simulation model, which is capable of predicting the drying quality of radiata pine boards, was developed in this paper for pre-grading and for setting of drying schedules in sawmills. Moreover, Logs must be sawn into slabs before drying. Accordingly, the geometrical configurations of boards were generated. Next, the structures of knot-containing boards were modelled on the basis of the growth features of branches. Later, the 2D and 3D scenario simulations of different knot shapes and knot types were performed and illustrated specifically. In the last, the key points in the model development were found and stated.
Synergy Effect of PEG and LiCl as Additives on PVDF UF Membrane Performance
Authors: Zhang Li Qing , Zhang Gang
Published: October 2014

PVDF flat UF membranes were optimized to get relative high protein rejection with high permeation fluxes. The effects of PVDF content and the additive species on the membrane performance were investigated. The synergy effect between LiCl and PEG8kcan increase the flux remarkably than the single additive. With the increase of PEG8kcontent, the synergy effect of LiCl decreased. In addition, when the PEG8kcontent was higher than LiCl, the pure water flux was relatively high, while with the increasing of LiCl content, the membrane tensile strength was increased. The addition of PEG8kand LiCl should constitute an appropriate method to prepare a series of membranes with controlled flux.

Published: October 2014

The effect of doffer speed on fiber length distribution in flat strips was studied. The fiber length of flat strips produced at three doffer speeds was tested by Premier aQura neps and short fiber tester. The test results show that 1fiber length in flat strips is between 6-38 mm; 2doffer speed has some effect on flat strips quality, which is best at the doffer speed of 20r/min; 3 3% ,5% fiber length and effective fiber length at the doffer speed of 25r/min are better than those at the doffer speed of 30r/min, but short fiber content (<12.7mm and <16 mm ) at the doffer speed of 25r/min are less than those at the doffer speed of 30r/min 4 from the viewpoint of fiber length distribution, the doffer speed of 30r/min is better than that of 25r/min; 5it may not be complete only using fiber length parameters to judge the carding effect, and the fiber length distribution may be more accurate to evaluate the carding process.
Stochastic Process Model for the Optimization of a Rotorcraft with Categorical Variables
Authors: del Río José Valenzuela , Mavris Dimitri
Published: October 2014

This paper proposes an improved stochastic process model for the selection of categorical variables, such as airfoils and materials, in rotorcraft design. This process leverages trends in typical rotorcraft conceptual design objectives that are similar across different categories. Also,
this paper extends the use of efficient global optimization (EGO) algorithms, which intelligently search design spaces, to the previously proposed stochastic process thereby enabling the use of more computationally intensive tools earlier in the design process. To optimize the EGO infill criterion,
a genetic algorithm is developed that is capable of searching domains with categorical variables. The proposed stochastic process model is successfully tested against traditional independent surrogates when approximating the engine shaft horsepower of the UH-60A with a choice of airfoils.
Finally, a test to optimize the UH-60A engine shaft horsepower at two flight conditions demonstrates that the proposed extension of the EGO algorithm is more efficient at finding the Pareto fronts than the current state-of-the-art.

Authors: Robinson P T , Gibson I L , Panayiotou A
Published: October 2014

Two holes were drilled in the Agrokipia ore deposits of the Troodos ophiolite in order to investigate the nature of hydrothermal circulation and ore formation in oceanic crust. Hole CY-2 penetrated 226 m beneath the Agrokipia 'A' deposit with 92% recovery. lt
sampled 100 m of hydrothermally altered lavas before passing into relatively fresh, glassy rocks. Hole CY-2a, located directly above the Agrokipia 'B' deposit, penetrated 154 m of weakly altered lavas, 143 m of hydrothermally altered and mineralized rock, and 392 m of highly altered dykes and pillow
screens. Recovery in CY-2a averaged about 93%, being lowest in the hydrothermally altered section. Of the 97 days spent at these two sites, only 60 were actually used in drilling operations, giving an average penetration rate of just over 15 m per day. The recovered core was washed, fitted
together and described on site. Units were defined on the basis of cooling breaks and changes in grain size, lithology, mineralogy or degree of alteration. One hundred and nine units were recognized in hole CY-2 and 373 in hole CY-2a. These units were grouped into larger scale lithologic units for
comparison with exposed sequences. The core is stored in Nicosia, Cyprus and may be sampled upon application to the Chairman of the International Crustal Research Drilling Group. Use of the core for further study is encouraged.
A Review of the Pathogenesis of Osteoarthritis and the Use of Intra-articular Platelet Therapy for Joint Disease in Animals and Humans
Authors: Ortolano Girolamo A. , Wenz Barry
Published: October 2014

Osteoarthritis (OA) is the most prevalent musculoskeletal disease in humans and domestic animals. It causes significant clinical problems and substantial health care costs. In the absence of disease-modifying medical intervention, therapy is currently restricted to palliative measures prior to surgical intervention.

We review the pathogenesis, as well as conservative and emerging restorative therapeutic approaches, including cytokines, stem cells, and platelets. The various methods of platelet concentrate preparations and their reported outcomes are discussed. Data collected from the use of intra-articular platelet therapy (IAPT) in dogs are reviewed, which suggest that this approach may delay or in some cases even obviate the need for surgical intervention.
