A simplified approach to design for assembly

The basic principles of design for assembly (DfA) are well established. This paper presents a short review of the development of DfA approaches before presenting a new tool in which these principles are packaged for use in teams, both in an industrial and an educational context. The fundamental consideration in the design of this tool is to encourage wide team participation from across an organisation and is thus physical rather than software-based. This tool builds on the process developed by Appleton whilst at the University of Cambridge. In addition to the traditional analysis of component fitting, feeding and fixing, this process also encourages the team to explore how this relates to the overall assembly flow and specifically the achievement of throughput targets. The novel approach is an improvement to established methods and encompasses an original assessment tool and its delivery process that includes custom designed post-it notes and simple check lists for scoring. The process is demonstrated in a single case study in an Indian firm.
Characterization of graphene through anisotropy of constant-energy maps in angle-resolved photoemission

We theoretically show how constant-energy maps of the angle-resolved photoemission intensity can be used to test wave function symmetry in graphene. For monolayer graphene, we demonstrate that the observed anisotropy of angle-resolved photoelectron spectroscopy spectra is a manifestation of what has been recently branded as an electronic chirality. For bilayer graphene, we show that the anisotropy of the constant-energy maps may be used to extract information about the magnitude and sign of interlayer coupling parameters and about symmetry breaking inflicted on a bilayer by the underlying substrate.
Sequences Analysis of a Gene Encoding Extracellular Xylanase in Streptomyces costaricanus 45I-3

Streptomyces costaricanus 45I-3 is a bacterial strain belongs to actinomycetes group isolated from peat soil. The bacterium is known to produce extracellular xylanase. The aims of this study were to analyze DNA sequence and sub-clone gene involved in the synthesis of extracellular xylanase. Complete DNA sequence predicted to encode xylanase genes was isolated from bacterial genome using Inverse Polymerase Chain Reaction (I-PCR). Total DNA sequence of 1664 bp in size obtained from I-PCR consisted of two open reading frames (ORF) in opposite direction. ORF1 was 1029 bp and ORF2 (partial sequence) was 309 bp. Analysis sequence using BlastX indicated that ORF1 was homologous with xylanase bacterium enrichment culture clone Xyl8B8 (GenBank accession No. AFH35005.1), i.e. 95% in identity and 99% in similarity. In addition, ORF2 was homologous with glyoxalase bacterium enrichment culture clone Xyl8B8 (GenBank accession No. AFH35007.1), i.e. 95% in identity and 98% in similarity. Analysis of amino acid sequence revealed that ORF1 consisted of 2 domains, i.e. glyco-hydrolase 11 (GH11) and Carbohydrate Binding Type 2 (CBM2). Active site was found at 130 th amino acid on GH11 domain. Visualization of 3-dimension structure showed that 1029 bp fragment is of 19 areas.
Use of Geo-referenced Images with Unmanned Aerial Systems

This contribution presents recent results on the use of georeferenced satellite or aerial images with Unmanned Aerial Vehicles (UAV). The paper describes two different applications. Outdoor autonomous UAVs rely on the GPS signal in order localize themselves in the environment. If the GPS is unavailable the UAV is blind and cannot navigate safely. The GPS signal is quite weak and can be jammed easily therefore a method how to cope with short and long term GPS fallouts is essential for a safe UAV operation. The first application shows how reference images can be used to localize and navigate a UAV in case the GPS is unavailable. Experimental results using a UAV helicopter platform will be presented. The second application describes how the use of a reference image can improve the ground object geo-location capability of a fixed-wing Micro Aerial Vehicle (MAV) of only 400 grams. Such small platforms have a low kinetic energy therefore are reasonably safe for humans. On the other hand their limited payload capabilities does not allow to carry accurate sensors on-board. The use of reference images improves the ground target localization accuracy for MAV platform with limited sensor accuracy.
Extending seasonal predictability of Yangtze River summer floods

Abstract. Extreme pluvial floods across China's Yangtze River basin in the summer of 2016 were strongly connected with intense atmospheric moisture transport, and resulted in vast loss of properties after a strong El Niño winter. Predicting such extreme floods in advance is essential for hazard mitigation, but the flood forecast skill is relatively low due to the limited predictability of summer precipitation. By using a “perfect model” assumption, here we show that atmospheric moisture flux has a higher potential predictability than precipitation over the Yangtze River at seasonal timescales. The predictability of precipitation and moisture flux is higher in post-El Niño summers than in post-La Niñas, especially for flooding events. As compared with extreme precipitation, the potential detectability of extreme moisture flux increases by 20 % in post-El Niño summers, which suggests that atmospheric moisture flux could be crucial for early warning of Yangtze River summer floods.
Analysis Of The Benefits Of Intra-Port Competition

Intra-port competition is widely regarded as beneficial, for the competitiveness of ports, for local and national economies and for consumers and exporting industries. The aim of the paper is to analyse the benefits resulting from the presence of intra-port competition. Even though this issue has been addressed before, a thorough and complete overview of the effects of intra-port competition, enabling conditions for intra-port competition and policies in case of lacking intra-port competition are absent. The paper presents first a short overview of previous studies dealing with intra-port competition. Second, it discusses the two main arguments underlying the benefits of intra-port competition. In this context, attention is given to the relation between intra-port and inter-port competition. Third, the paper examines the conditions under which these arguments are valid and intra-port competition can be introduced. Possible policy responses to limited or absent intra-port competition are discussed in this section as well. Fourth, the need to introduce effects of intra-port competition in port modelling is briefly. Finally, the paper presents empirical evidence of the effects of intra-port competition.
Economic valuation of marine protected areas: a review of studies in Southeast Asia

Marine Protected Areas (MPAs) are key habitats for the conservation of important marine resources. However, most of the MPAs in the world are mismanaged. This paper provides a review of some of the valuation studies on marine protected areas in Southeast Asia. The purpose of this paper is to examine whether economic valuation provides valuable information to policy makers to mitigate the problems in marine protected areas in Southeast Asia. There are 17 studies related to marine protected areas in Southeast Asia that are discussed in this paper in order to determine their implications in policy decisions. Findings from these studies are inferred to maintain sustainable marine resource management in Southeast Asia. Results from this study suggest that more research is needed, as there are limited literatures on this important issue. Moreover, economic valuation is able to provide vital information in policy implications.
Feature Based Stereo Matching Using Two-Step Expansion

This paper proposes a novel method for stereo matching which is based on image features to produce a dense disparity map through two different expansion phases. It can find denser point correspondences than those of the existing seed-growing algorithms, and it has a good performance in short and wide baseline situations. This method supposes that all pixel coordinates in each image segment corresponding to a 3D surface separately satisfy projective geometry of 1D in horizontal axis. Firstly, a state-of-the-art method of feature matching is used to obtain sparse support points and an image segmentation-based prior is employed to assist the first region outspread. Secondly, the first-step expansion is to find more feature correspondences in the uniform region via initial support points, which is based on the invariant cross ratio in 1D projective transformation. In order to find enough point correspondences, we use a regular seed-growing algorithm as the second-step expansion and produce a quasi-dense disparity map. Finally, two different methods are used to obtain dense disparity map from quasi-dense pixel correspondences. Experimental results show the effectiveness of our method.
Wave Motion and Stop-Bands in Pipes with Helical Characteristics Using Wave Finite Element Analysis

Pipes are widely used in many industrial and mechanical applications and devices. Although there are many different constructions according to the specific application and device, these can show helical pattern, such as spiral pipes, wire-reinforced pipes/shells, spring-suspension, and so on. Theoretical modelling of wave propagation provides a prediction about the dynamic behavior, and it is fundamental in the design process of these structures/devices and in structural health monitoring techniques. However, standard approaches have limitations in terms of difficulties in modelling and impossible computational cost at higher frequencies. In this study, the wave characteristics in waveguides with helical patterns are obtained using a Wave Finite Element (WFE) method. The method is described for a 1D and 2D waveguide with helical properties and it is illustrated by numerical examples. These include the optimization of stop-bands for a fluid-filled pipe with concentrated masses and a cylindrical structure with helical orthotropy.
The Role of Physical Facilities in Mediating the Relationship Between Quality of Service Personnel and Service Environment on Service Perceptions of Airport Services

The Kuala Lumpur International Airport (KLIA) has been the gateway to exciting cities in South East Asia and in 2010 was ranked the 9th busiest international airport in the world. Even though KLIA has been an international airport for many years, it is difficult for it to compete with other international airport within the same categories such as the Incheon airport in Korea and Changi airport in Singapore. This scenario begs the question what are the main determinants that influence customer’s perceptions on the services offered by these international airports. In this paper, the author attempts to measure the airport stakeholders’ perception pertaining to the services offered by KLIA as one of the best airport in the world. A total of 456 respondents were selected from three types of respondent: namely passengers, airport personnel and airport tenants by using purposive quota sampling. Three predictors, service quality, service environment and service personnel were found to have medium to high correlation with the dependent variables, service perception. Further multiple regression test showed that the predictor variable, airport facilities was found to mediate the relationship between service quality and service environment on service perception. The strength of association between service quality and service environment was reduced with the introduction of the predictor, airport facilities indicating the mediating effect of airport facilities. Furthermore, the R square value increases from 0.637 to 0.642 showed the partial mediation effect of airport facilities. The outcome of the study is useful in providing the direction towards sustaining and improving not only the intangible but the tangible components of airport facilities in the country as one of the element in building the image and reputation as one of the busiest airport in the world.
Multivalued $F$-contractions and related fixed point theorems with an application

In this paper, we introduce the notions of $\alpha$-$F$-contractions, by combining the notions of $\alpha$-$\psi$-contraction and $F$-contraction. Using our new notions we obtain some fixed point theorems for multivalued mappings. As an application we establish an existence theorem for integral equations. An example is also constructed to show an importance of our results.
DEVELOPMENT OF SEAFOOD ONTOLOGY FOR SEMANTICALLY ENHANCED INFORMATION RETRIEVAL

Today massive amount of information is stored on the Web and on large document repositories. People use search engines such as Yahoo, Google, MSN etc to find and share this information. But since search engines are limited to grasp the meanings of the user needs, sometimes it is difficult to get the exact information of search. Now the potential solution to this problem is to have a meaningful search. Ontologies were introduced as the conceptual framework of semantic search in late 90’s. They are the backbone of Semantic Web and they include the descriptions of classes, properties and their instances. Nowadays ontologies are being applied in a number of information retrieval systems to enhance the performance of such systems. In this paper we present seafood ontology to retrieve precise information about seafood. The different steps involved in the development process of the particular ontology are explained and classes, properties of classes and instances are described. Protege 4, the ontology editor and knowledge-base framework is used to represent the ontology. OWL [Web Ontology Language] is the most recent development in standard ontology languages, endorsed by the World Wide Web Consortium (W3C).
Fuzzy based segmentation of multiple sclerosis lesions in Magnetic Resonance brain images

Segmentation is an important step for the diagnosis of multiple sclerosis. This paper presents a new approach for fully automatic segmentation of MS lesions in fluid attenuated inversion recovery (FLAIR) Magnetic Resonance (MR) images. At first, Brain image is considered to be three parts, namely the dark, the gray, and the white part. Then, the fuzzy regions of their member functions are determined by maximizing fuzzy entropy through the Genetic algorithm. Finally, MS lesions and CSF areas are determined by applying a localized weighted filter to the Bright and Dark membership images. To evaluate the result of the proposed method, similarity criteria of different slices related to 20 MS patients are calculated and compared with other methods which include manual segmentation. Also, volume of segmented lesions are computed and compared with Gold standard using correlation coefficient. The proposed method has better performance in comparison with previous works which are reported here.
Vertical axis wind turbines: minimising generator losses by torque control

Vertical Axis Wind Turbines (VAWTs) tend to produce mechanical torque which varies significantly with rotor azimuth angle. The cost of the electrical generator is related to the peak generator torque which in turn depends on the choice of torque/speed control strategy. This choice of control strategy also affects the copper and iron losses of the generator; these can be modelled using harmonic analysis. The paper demonstrates how an optimal control strategy (from a generator loss point of view) can be achieved without significant extra cost.
The First Silesaurid Dinosauriform from the Late Triassic of Morocco

Disarticulated material from the Late Triassic Timezgadiouine Formation in the Argana Basin of Morocco represents a new taxon of silesaurid dinosauromorph, Diodorus scytobrachion gen. et sp. nov. D. scytobrachion can be distinguished from other silesaurids by the presence of anteriorly-canted teeth that decrease in size towards the anterior end of the dentary and a distinct lateral ridge running parallel to the dentary alveolar margin. In a phylogenetic analysis, D. scytobrachion is recovered as the sister-taxon to the Brazilian Sacisaurus agudoensis, nested deep within Silesauridae. This new taxon provides further evidence of a near-cosmopolitan range for basal dinosauriforms in the Late Triassic and further demonstrates the disparity of dental morphologies within Silesauridae.
Strangulation Obstruction and the Release of Strangulation. Effects of Fluid Administration on Mucosal Blood Flow and Damage

Background/Purpose: This study evaluates bowel mucosa damage and the consequences of crystalloid fluid administration on mucosa damages upon release from strangulation obstruction. Secondary outcomes are metabolic and hemodynamic changes during and after release of strangulation obstruction. Methods: Twenty-four anesthetized pigs were subject to strangulation of the distal ileum for 185 min. Variables and specimens were registered and collected during strangulation and for 25 min thereafter. Intravenous Ringer`s acetate infusion during strangulation obstruction and after release of strangulation was 15 mL·kg-1·h-1 in group I (Standard infusion) and 55 mL·kg-1·h-1 in group II (High infusion). Group III, (Sham) controls received 15 mL·kg-1·h-1 throughout the experiment. Results: Strangulation obstruction reduced bowel blood flow from baseline averages of 2.9-3.8 ml·min-1·g-1 to 0.3-0.9 ml·min-1·g-1. Upon release of strangulation, the bowel blood flow remained low in the standard infusion group but increased significantly towards baseline levels in the high infusion group. Strangulation damaged more mucosa with standard infusion (80% ± 13%) than high infusion (25% ± 6%) (p=0.032). Release of strangulation had no significant effect on the mucosa (72% ± 17% and 41% ± 15% damage, respectively). Mucosal cell proliferation fell during strangulation from 169 mm-1 ± 17 mm-1 in controls to 71 mm-1 ± 16 mm-1 in standard (p<0.05) and 120 mm-1 ± 16 mm-1 in high infusion group. Release of strangulation significantly increased cell proliferation towards control levels. Serum base excess decreased significantly during strangulation and release of strangulation in both intervention groups. S-lactate increased significantly in blood from the strangulated loop, but only in peripheral blood of the standard infusion group. Conclusion: Careful observation for hypotension, tachycardia and biochemical changes related to metabolic acidosis may contribute to early recognition of intestinal strangulation obstruction. Enhanced intravenous fluid administration reduces bowel damages and hemodynamic consequences of both strangulation and release of strangulation. Reperfusion damages should not be expected upon release of strangulation in the strangulated bowel and signs of bowel restitution appear early.
Evaluation of antioxidant potential of natural xanthone mangiferin in myocardium- A rat model study

Mangiferin, a glucosylxanthone found in Mangifera indica, reported to have a wide range of pharmacological properties. The objective of this study was to evaluate the antioxidant potential of mangiferin against arsenic trioxide induced myocardial oxidative stress in rats. Our earlier studies have revealed the oxidative stress inducing capacity of arsenic trioxide (As2O3), hence in the present study we have administered 4 mg/kg bwt of As2O3 to generate oxidative stress in myocardium. The antioxidant effect of mangiferin against arsenic induced toxicity was assessed by using biochemical parameters like reduced glutathione (GSH), glutathione-S-transferase (GST), glutathione peroxidase (GPx), superoxide dismutase (SOD), catalase (CAT) and thiobarbituric acid reactive substances (TBARS). Cotreatment with mangiferin (100 mg/kg b.wt) for 30 days significantly (p < 0.05) inhibited the arsenic induced decrease in GSH, GST, GPx, SOD, and CAT levels. The mangiferin also protected the heart from lipid peroxidation. Taken together, our study revealed that mangiferin has potent antioxidant effect against arsenic trioxide induced toxicity in rat myocardium and which may be attributed to decrease in arsenic induced reactive oxygen species levels and resultant oxidative stress.
Forage potential of black oat Iapar 61 alone or in association with birdsfoot trefoil

The objective of this study was to evaluate the structural characteristics, dry matter production, residual mass, chemical composition and in vitro dry matter digestibility of Iapar 61 black oat ( Avena strigosa cv Iapar 61) pasture, both in isolation and in association with birdsfoot trefoil ( Lotus corniculatus L., cv. St. Gabriel), under different forms of management in three growth cycles. A randomized block design was used with split plots in time with four treatments: conventional tillage oats, oat tillage, oats associated with birdsfoot trefoil and single birdsfoot trefoil, with three periods of evaluation and four replications. The apical meristem of oats increased from the first to the second cycle. The dry matter production of single birdsfoot trefoil was 579.65 kg on average, and the oats tillage production was 2597.78 kg. Oats exhibited high nutritional value before the first grazing in all treatments; however, at the end of its cycle, the association with birdsfoot significantly increased the crude protein content of the forage. The in vitro dry matter digestibility was similar between crops and decreased in the third cycle. Birdsfoot increased the nutritional value of oats at the end of the oat life cycle. El objetivo de este estudio fue evaluar las caracteristicas estructurales, la produccion de materia seca, masa residual, composicion quimica y digestibilidad de la materia seca in vitro de la avena negra ( Avena strigosa ) Iapar 61, sola y en asociacion con la lotera ( Lotus corniculatus L., cv. San Gabriel), bajo diferentes formas de manejo, en tres ciclos de crecimiento. El diseno experimental fue de bloques al azar con parcelas divididas en el tiempo, con tres tratamientos: avena con siembra convencional, avena con siembra directa, avena asociado con la lotera con tres periodos de evaluacion y cuatro repeticiones. El meristema apical de la avena fue incrementandose desde la primera hasta el segundo ciclo. La produccion de materia seca de la lotera sola fue baja en todos los periodos con una media de 579,65 g kg -1 , mientras que la produccion de avena sola con siembra convencional fue de 2.597 kg ha -1 . La avena revelo un alto valor nutricional antes del primer pastoreo en todos los tratamientos; sin embargo, al final de su ciclo, la asociacion con lotera contribuyo a elevar el contenido de proteina cruda del forraje, debido a que esta es la etapa final de su ciclo. La digestibilidad de la materia seca in vitro fue similar entre los cultivos evaluados con una disminucion en el tercer ciclo. La asociacion promovio mejora el valor nutricional de la avena asociados con lotera al final del ciclo de la avena.
A FRAMEWORK FOR ELECTRONIC COMMERCE ADOPTION: A STUDY IN KADUNA STATE, NIGERIA

The paper proposes a framework that integrates Perceived Credibility, Perceived Regulation, Perceived Benefit, Perceived Awareness/Education with the Unified Theory of Acceptance and Use of Technology (UTAUT) concept in users’ adoption of e-commerce in Kaduna State, Nigeria. The findings show that while the original UTAUT model suggests a positive relationship between its variables and Behavioral Intention, it appears that the data do not support a significant relationship between these concepts. However, significant relationships were identified between performance expectancy, effort expectancy, facilitating conditions, perceived regulation on behavioural intention to adopt e-commerce. Unfortunately, no significant relationships were found between social influences, Perceived credibility, Perceived Benefit, Perceived awareness/education with respect to Behavioral Intention.
