Application of pre-whitened-constrained-MUSIC in ship-borne radar

In ship-borne radar, because of the influence of interference factors such as the correlation of background array noise and the coherence of targets and so on, the performance of high-resolution algorithms such as MUSIC is degraded. In this document by pre-whitening of background array color noise, de-correlation of coherent targets, compensation of amplitude-phase mismatch, pre-whitened-constrained-MUSIC algorithm in ship-borne radar effectively resolutes ship target and first-order sea echo. Furthermore, the algorithm performance is compared with other algorithms, result shows that pre-whitened-constrained-MUSIC can be applied effectively in high-resolution processing in ship-borne radar.

Minor Component Analysis-based Landing Forecast System for Ship-borne Helicopter

The general structure of ship-borne helicopter landing forecast system is presented, and a novel ship motion prediction model based on minor component analysis (MCA) is built up to improve the forecast effectiveness. To validate the feasibility of this landing forecast system, time series for the roll, pitch and heave are generated by simulation and then forecasted based on MCA. Simulation results show that ship-borne helicopters can land safely in higher sea condition while carrying on rescue or replenishment tasks at sea in terms of the landing forecast system.

Location and allocation problem for spare parts depots on integrated logistics support

In equipment integrated logistics support(ILS), the supply capability of spare parts is a significant factor. There are lots of depots in the traditional support system, which makes too many redundant spare parts and causes high cost of support. Meanwhile,the inconsistency among depots makes it difficult to manage spare parts. With the development of information technology and transportation, the supply network has become more efficient. In order to further improve the efficiency of supply-support work and the availability of the equipment system, building a system of one centralized depot with multiple depots becomes an appropriate way.In this case, location selection of the depots including centralized depots and multiple depots becomes a top priority in the support system. This paper will focus on the location selection problem of centralized depots considering ILS factors. Unlike the common location selection problem, depots in ILS require a higher service level. Therefore, it becomes desperately necessary to take the high requirement of the mission into account while determining location of depots. Based on this, we raise an optimal depot location model. First, the expected transportation cost is calculated.Next, factors in ILS such as response time, availability and fill rate are analyzed for evaluating positions of open depots. Then, an optimization model of depot location is developed with the minimum expected cost of transportation as objective and ILS factors as constraints. Finally, a numerical case is studied to prove the validity of the model by using the genetic algorithm. Results show that depot location obtained by this model can guarantee the effectiveness and capability of ILS well.

An MILP approach for detailed scheduling of oil depots along a multi-product pipeline

Oil depots along products pipelines are important components of the pipeline transportation system and down-stream markets.The operating costs of oil depots account for a large proportion of the total system’s operating costs.Meanwhile,oil depots and pipelines form an entire system,and each operation in a single oil depot may have influence on others.It is a tough job to make a scheduling plan when considering the factors of delivering contaminated oil and batches migration.So far,studies simultaneously considering operating constraints and contaminated oil issues are rare.Aiming at making a scheduling plan with the lowest operating costs,the paper establishes a mixed-integer linear programming model,considering a sequence of operations,such as delivery, export, blending,fractionating and exchanging operations,and batch property differences of the same oil as well as influence of batch migration on contaminated volume.Moreover,the paper verifies the linear relationship between oil concentration and blending capability by mathematical deduction.Finally,the model is successfully applied to one of the product pipelines in China and proved to be practical.

Field measurement and evaluation of vibration in different areas of a metro depot

This paper presents a study of the characteristics of a railway vibration at three key sections containing different track structures in a metro depot.The results show that the vertical and horizontal vibration acceleration levels are proportional to train speed.The Z-weighted vertical acceleration levels obtained showed that the vibration source strengths at the ballast foot of the testing line and the throat area were very close.The vibration attenuation at the repair line was larger than that of the testing line.In the throat area,the peak frequency of vibration obtained at the ballast foot(2.5 m)could be shifted to a lower frequency band by using polyurethane sleepers instead of standard concrete sleepers.Polyurethane sleepers can help to reduce vertical vibration in a frequency band of 0-10 Hz.The vibration levels would satisfy the limits given in the ISO2631-2-2003(2013)for any location more than 5 m away from the source at the testing line and 2.5 m away from the source at the repair line and throat area.

Adipose-derived stromal/stem cells from different adipose depots in obesity development

The increasing prevalence of obesity is alarming because it is a risk factor for cardiovascular and metabolic diseases(such as type 2 diabetes). The occurrence of these comorbidities in obese patients can arise from white adipose tissue(WAT) dysfunctions, which affect metabolism, insulin sensitivity and promote local and systemic inflammation. In mammals, WAT depots at different anatomical locations(subcutaneous, preperitoneal and visceral) are highly heterogeneous in their morpho-phenotypic profiles and contribute differently to homeostasis and obesity development, depending on their ability to trigger and modulate WAT inflammation. This heterogeneity is likely due to the differential behavior of cells from each depot. Numerous studies suggest that adiposederived stem/stromal cells(ASC; referred to as adipose progenitor cells, in vivo)with depot-specific gene expression profiles and adipogenic and immunomodulatory potentials are keys for the establishment of the morphofunctional heterogeneity between WAT depots, as well as for the development of depot-specific responses to metabolic challenges. In this review, we discuss depot-specific ASC properties and how they can contribute to the pathophysiology of obesity and metabolic disorders, to provide guidance for researchers and clinicians in the development of ASC-based therapeutic approaches.

THE ASSOCIATION OF Ala54Thr VARIANT OF INTESTINAL FATTY ACID BINDING PROTEIN GENE WITH GENERAL AND REGIONAL ADIPOSE TISSUE DEPOTS

Objective. To ascertain the relationship between the Ala54Thr variation of FABP2 gene and general as well as regional adipose tissue depots. Subjects. 165 subjects, in which 86 were subjects with normal glucose tolerance (NGT) [age 54 45±9 80, male/female 1 05,body mass index (BMI)26 48±4 01] and 79 were subjects with non insulin dependent diabetes mellitus (NIDDM)(age 55 86±10 00,male/female 1 08,BMI 26 75±3 30). Design and measurements. An association study of FABP2 Ala54Thr variation detected by PCR/HhaI digestion with general and regional adipose tissue depots determined by BMI and magnetic resonance imaging [abdominal subcutaneous and visceral adipose tissue area (SA and VA) and femoral subcutaneous adipose tissue area (FA)]. Results. The geneotype and allele frequencies of FABP2 Ala54Thr variation in Chinese were quite close to the frequencies in American Caucasians and Pima Indians reported in the literature. Significant difference in genotype frequency distribution was observed between FA subgroups comparisons (FA≥75cm 2 versus FA<75cm 2 )in NIDDM subjects (X 2 =11 460,P=0 003),with significantly increased in Thr54 carrier[Thr54(+)]genotype frequency and Thr54 allele frequency in NIDDM subject with FA<75cm 2 (odd ratio for genotype was 4 62,X 2 =10 112,P=0 001;and for allele=2 36,X 2 =5 379,P=0 020).The FA in NIDDM Thr54(+)subgroup was significantly lower than that in subjects with NIDDM Thr54( )sugroup(61 19±21 51cm 2 versus 75 36±31 70cm 2 ,P=0 021). Stepwise regression analysis revealed that FABP2 Thr54 genotype variation was an independent factor contributing to the variation of FA in NIDDM(P=0 003). Conclusion. FABP2 is associated with regional adipose tissue depot.The decreased femoral subcutaneous adipose tissue depot in NIDDM subjects is related to FABP2 Thr54 variant.

Improving beef hamburger quality and fatty acid profiles through dietary manipulation and exploitation of fat depot heterogeneity

Background： Hamburger is the most consumed beef product in North America, but lacks in nutritional appeal due to its high fat content and high proportion of saturated fatty acids （SFA）. Objectives of the present study were to improve the FA profiles of hamburgers made with perirenal fat （PRF） and subcutaneous fat （SCF） when feeding steers different diets along with examining differences in sensory attributes and oxidative stability. Diets included a control diet containing 70：30 red clover silage： barley based concentrate, a diet containing sunflower-seed （SS） substituted for barley, and diets containing SS with 15% wheat dried distillers＇ grain with solubles （DDGS-15） or 30% DDGS （DDGS-30）. Hamburgers were made from triceps brachii and either PRF or SCF （80：20 w/w）. Results： Perirenal fat versus SCF hamburgers FA had 14.3% more （P 〈0.05） 18：0, 11.8% less cis （c）9-18：1 （P 〈0.05）, and 1.82% more total trdns （t）-18：1 mainly in the form of tl 1-18：1. During sensory evaluation, PRF versus SCF hamburgers had greater （P 〈0.05） mouth coating, but the difference was less than one panel unit. Examining effects of steer diet within PRF hamburgers, feeding the SS compared to the control diet increased （P 〈0.05） t-18：1 by 2.89% mainly in the form of tl 1-18：1, feeding DGGS-15 diet led to no further changes （P 〉0.05）, but feeding DDGS-30 diet reduced the proportions of （P 〈0.05） of t-18：1 chiefly tl 1-18：1. Feeding SS and DDGS diets had small but significant （P 〈0.05） effects on hamburger sensory attributes and oxidative stability. Conclusions： Feeding high-forage diets including SS and 15% DDGS, and taking advantage of the FA heterogeneity between fat depots offers an opportunity to differentially enhance beef hamburgers with 18：2n-6 biohydrogenation products （Le., t11-18：1） with potential human health benefits without compromising their sensory attributes and oxidative stability during retail display.

The Profile of Abundant and Essential Fatty Acids in Depot Fat Varies More in Kiwi (<i>Apteryx mantelli</i>) than in Other Avian Species

Direct and dendrographic comparison of the profiles of abundant fatty acids in depot fat was unable to separate 10 avian species on a basis of their overall proportions but was able to distinguish broad dietary groups or those in a habitat with distinctive nutritional characteristics such as avian marine carnivores. In all species considered, including North Island brown kiwi (Apteryx mantelli), oleic (C18:1) and palmitic acids (C16:0) were most abundant. The relative proportions of linolenic (C18:3) acid were 4% or lower across all species, while the relative proportions of palmitoleic acid (C18:0) were less than 7% in nine of the avian species, with the exception being the insectivorous red-eyed vireo (Vireo olivaceous). The levels of linoleic acid (C18:2) were lower in avian marine carnivores than in avian herbivores, insectivores, and omnivores. Whilst the mean values of the individual fatty acids in fat from various avian species were separated by hierarchical cluster analysis, the wide range of values of each fatty acid precluded any correlation of clustering with any known variation in dietary items. Similarly, the wide range in fatty acid composition of kiwi fat rendered it unhelpful in determining the optimum composition of the captive diet.

SHAPING COURSE. The Development of the Strategy for the e-Depot of the Koninklijke Bibliotheek, National Library of the Netherlands, in a National and International Context

Operating an international archive for digital information resources by a relatively small organization as the Koninklijke Bibliotheek (KB) asks for a firm foundation of its policy. Continuing research and development efforts to secure permanent preservation and access to electronic information on a national and international scale require substantial financial, technical and staffing commitments. Cooperation in sharing resources and knowledge is called for. In the national context of the Netherlands the KB recently took the initiative to build the National Digital Preservation Coalition. All relevant sectors of Dutch society are represented. Its aim is to develop a national infrastructure and to assign clear responsibilities. In the European arena the KB, together with the British Library, started the European Alliance for Permanent Access to the Records of Science. The Alliance works towards the widespread and joint responsibility for maintaining the records of science by all major stakeholders, including national governments and the EU. In the global context the KB developed the concept of the "Safe Places Network" . This Network will include a limited number of institutions with certified digital archives for scientific publications, sharing responsibility for complete, world-wide coverage and allocate tasks accordingly.

Research on rail wear of small radius curve in EMU depot

Purpose–With the help of multi-body dynamics software UM,the paper uses Kik–Piotrowski model to simulate wheel-rail contact and Archard wear model for rail wear.Design/methodology/approach–The CRH5 vehicle-track coupling dynamics model is constructed for the wear study of rails of small radius curves,namely 200 and 350 m in Guangzhou East EMU Depot and those 250 and 300 m radius in Taiyuan South EMU Depot.Findings–Results show that the rail wear at the straight-circle point,the curve center point and the circlestraight point follows the order of center point>the circle-straight point>the straight-circle point.The wear on rail of small radius curves intensifies with the rise of running speed,and the wearing trend tends to fasten as the curve radius declines.The maximum rail wear of the inner rail can reach 2.29 mm,while that of the outer rail,10.11 mm.Originality/value–With the increase of the train passing number,the wear range tends to expand.The rail wear decreases with the increase of the curve radius.The dynamic response of vehicle increases with the increase of rail wear,among which the derailment coefficient is affected the most.When the number of passing vehicles reaches 1 million,the derailment coefficient exceeds the limit value,which poses a risk of derailment.

This study examines the phenomena of the hormone-active fibers obtaining process, in the form of artificial insulin depot. As a fibrous carrier of insulin cation-exchange polyacrylonitrile (PAN) fibers and biodegradable polysaccharide alginate fibers were used. The process of obtaining fibrous artificial insulin depot was based on the chemisorption of insulin from insulin aqueous solutions by these fibers. The parameters of insulin chemisorption reaction were determined and their influence on quantities of bonded insulin in the artificial depot was studied. The impact of fiber polymer nature on the intensity of insulin chemisorption was studied and determined. Also, the location and deposition of insulin in and onto the fiber, fiber topography were studied. The maximum amounts of bounded insulin for the cation-exchange PAN fibers were 395.0 mg porcine insulin chromatographic / g of fiber, and for the alginate fibers were about 300? mg of porcine insulin chromatographic / g of fiber.

A hybrid optimization approach for the heterogeneous vehicle routing problem with multiple depots cooperative operation

With the challenge of great growing of transport diversity for the automobile enterprises, the heterogeneous vehicle routing problem with multiple depots, multiple types of finished vehicles and multiple types of transport vehicles in finished vehicle logistics(HVRPMD) is modelled and solved. A multi-objective optimization model for HVRPMD is presented considering loading constraints to minimize the total cost and minimize the number of transport vehicles. Then a hybrid heuristic algorithm based on genetic algorithm and particle swarm optimization(GA-PSO) is developed. Moreover, a case study is used to evaluate the effectiveness of this algorithm. By comparing the GA-PSO algorithm with the traditional GA algorithm, the simulation results demonstrate the proposed GA-PSO algorithm is able to better support the HVRPMD problem in practice. Contributions of the paper are the modelling and solving of a complex HVRPMD in logistics industry.

Protective Measures to Oil Depot Against Lightning Stroke and Electrostatic Spark

Introduction Lightning can cause great destruction. According to the record in the northern China, more than 150 lightning strokes occur on a power system annually. High voltage (millions of volts) and large current (hundreds of -kA) associated with lightning, will damage property and even kill people and livestocks. It will be very dangerous if a lightning stroke strikes oil depot of power plant or substation. In addition, the high voltage induced by the electrostatic charge generated due to oil flowing will probably cause damage unless the electrification has been limited and drained off.
