Investigation of Structural Response of Reinforced Concrete Beams Strengthened with Anchored FRPs
Authors: Demakos Constantinos B. , Repapis Constantinos C. , Drivas Dimitrios
Published: November 2013

The beneficial effect of a composite material anchorage system (CMAS) upon the ductility and load capacity of
reinforced concrete (RC) beams strengthened either with glass (GFRP) or carbon (CFRP) fabrics was investigated. The
anchorage system consisted of U-shaped GFRP or CFRP strip (U-strip) at end of FRP. The U-strips were bonded around
the beam section and further anchored by two tufts of glass fibres, each of them embedded at the opposite beam face and
specifically in the region of compression zone of the beam web. Experimental evaluations in simply supported lightly reinforced
concrete (RC) beams strengthened with one GFRP or a CFRP sheet anchored at its ends by the composite anchorage
have shown that their bending capacity has increased by 8% and 17%, respectively, in relation to the capacity attained
in similar RC strengthened beams without anchorage. On the other hand, their ductility was improved by an
amount of 94% and 37%, respectively.
Study on Cuttings Starting Velocity in Air Drilling Horizontal and Highly-Deviated Wells

Published: November 2013

Air injection rate as the key parameter of drilling air is directly related to the success of drilling procedure. In
the previous studies, most of air injection rate models were built based on the vertical wells, which are not appropriate for
horizontal and highly-deviated well and limit the wide application of air drilling to some extent. Based on the movement
analysis of cuttings, this paper assumed that after the cuttings deposit to the low side of borehole, Air is injected to carry
the cuttings out of the wellbore. Then, the starting velocity model in different hole angles is established through the stress
analysis of cuttings motion, which can be used to calculate the minimum air injection rate. The numerical simulation
results show that starting velocity of cuttings reaches the maximum in the hole angle 60-70 degrees. The larger diameter
cuttings require a high starting velocity, which is difficulty to be transported. This means some appropriate methods
should be applied for air drilling procedure, like using secondary crush tools. The subsidence degree is one important
factor to the calculation model, and it is necessary to study cutting subsidence degree in next step.

Authors: Milatovic Dragan , Djurovic Dejan , Zec Gordan
Published: November 2013

Apricot cultivar assortment in Serbia is characterized by a small number of
cultivars and a short period of maturing. Most apricot fruits are harvested
in the season of cultivar ?Hungarian Best? or at a short time afterwards.
There is particularly a lack of early- and late-maturing cultivars of high
quality fruit. This study was aimed at evaluating of 14 introduced apricot
cultivars of late maturing time in order to recommend the best of them for
growing in the Belgrade region. The study was carried out at the Experimental
station ?Radmilovac? of the Faculty of Agriculture in Belgrade over a period
of five years (2009-2013). The experimental orchard was established in 2007,
the rootstock was Myrobalan seedling, and tree spacing was 4.5 x 3 m. Control
cultivar for comparison was ?Hungarian Best?, which is the most grown apricot
cultivar in Serbia. Flowering of introduced cultivars ranged from three days
before to three days after the control cultivar (?Hungarian Best?), while the
maturation time was 7 to 15 days after the control. Compared with the control
cultivar, significantly higher yield was achieved in seven cultivars
(?Harogem?, ?Umberto?, ?Litoral?, ?Sophia?, ?Harlayne?, ?Bergarouge?, and
?Silistrenska Kompotna?), while significantly higher fruit weight was
achieved in two cultivars (?Cegledy Arany? and ?Sophia?). Compared to the
control higher content of soluble solids was found in four cultivars
(?Kabaasi?, ?Late Dryanovska?, ?Harlayne?, and ?Silistrenska Kompotna?).
Cultivar ?Sophia? got the best score for fruit appearance, while cultivars
?Late Dryanovska? and ?Silistrenska Kompotna? got the best scores for taste.
Among studied apricot cultivars, for the cultivation in the Belgrade region,
the following cultivars can be recommended as promising: ?Sophia? for fresh
consumption, and ?Harlayne? and ?Silistrenska Kompotna? for processing. In
addition, five cultivars of combined traits (both for fresh consumption and
processing) can also be recommended: ?Harogem?, ?Cegledy Arany?,
?Bergarouge?, ?Pisana? and ?Late Dryanovska?.
Determining of root-knot nematode (Meloidogyne javanica) damage function for tomato cultivars
Authors: Gharabadiyan Fatemeh , Jamali Salar , Komeili Reza
Published: November 2013

Root-knot nematode (Meloidogyne javanica) management should be partly based
on the knowledge of the threshold density, and this value is likely to vary
depending on the resistance level of the tomato cultivars. The damage
functions based on four initial population densities (Pi) (0, 1,000, 3,000
and 5,000 egg kg-1 of soil) of root-knot nematode were determined in four
tomato cultivars. The experiment was performed in completely randomized
design with four replications. The results showed that yield responses to Pi
were fitted properly by a log-logistic function with three parameters. The
most susceptible cultivar was ?Rutgers? based on EP50 and EP10 (effective
population of nematodes, reducing 50% or 10% of maximum yield or shoot fresh
weight respectively) and three others were relatively resistant. EP10 is more
applicable than EP50 because 50% yield reduction is unacceptable in most
situations. EP10 for yield of ?Rutgers?, ?Efialto?, ?Falat 111?, ?Gina VF?
was 500, 3,021, 2,998, and 3,000 egg kg-1 of soil, respectively. The
correlation coefficients among gall index, egg mass and reproductive factors
were positively related. Reproduction factor and root gall indices were
greater in ?Rutgers? than in the other cultivars (P?0.05). For ?Gina VF? as a
relatively resistant cultivar it seemed that increasing of Pi up to 5,000 or
more egg kg-1 soil might break its resistance.
β-cyclodextrin-polyurethane polymer: A neutral and eco-friendly heterogeneous catalyst for the one-pot synthesis of 1,4-dihydropyridine and polyhydroquinolien derivatives via Hantzsch reaction under solvent-free conditions
Authors: Kiasat Ali , Nazari Simin , Davarpanah Jamal
Published: November 2013

An efficient synthesis of 1,4-dihydropyridine & polyhydroquinolien
derivatives using b-Cyclodextrin-polyurethane polymer (?-CDPU) as a
stationary microvessel and neutral heterogeneous catalyst via a four
component coupling of aldehydes, ?-ketoester (2 mol) and ammonium acetate
under solvent-free conditions is described. Compared with the classical
Hantzsch reaction, this new method has the advantages of good yield, short
reaction time and methodological simplicity. ?-CDPU was proved to be an
efficient heterogeneous catalyst which could be easily handled and removed
from the reaction mixture by simple filtration, and also recovered and
reused without loss of reactivity.

Published: November 2013

The synthesis of a new xanthine nitric oxide donor (TSP-81) has been
discussed. The designed compound includes two structural moieties -
theophylline (1,3-dimethylxanthine) and acetaminophen (4-hydroxyacetanilide)
linked by the nitric oxide donor alkyl chain as a spacer. The compound has
been characterized by microanalysis (CHN), 1H-NMR, 13C-NMR, FT-IR, UV-vis, TG
and DTG. The thermal behaviour showed that TSP-81 melts with decomposition,
in four steps, the most important ones being the 2nd one (the registered
weight loss being 17.6 %) and the 3rd one (with a registered weight loss of
30.4 %). The toxicity degree, the anti-inflammatory effect and the ability of
releasing nitric oxide of the TSP-81 have also been evaluated. The biological
assays established that TSP-81 exhibits enhanced biological properties such
as lower toxicity and higher anti-inflammatory effect in reference with
theophylline and acetaminophen, the drugs used as parents molecules. The
TSP-81 is approximately 2 times more active than theophylline and 4 times
more active than acetaminophen in reducing cotton pellet-granuloma formation.
Furthermore, the release of nitric oxide (NO) appears to have an important
contribution to enhancing the anti-inflammatory effect.

Authors: Marquezan Mariana , Lima Inayá , Lopes Ricardo Tadeu , Sant'Anna Eduardo Franzotti , de Souza Margareth Maria Gomes
Published: November 2013

Objective:

To compare the primary stability of miniscrews inserted into bone blocks of different bone mineral densities (BMDs) with and without cortical bone, and investigate whether some trabecular properties could influence primary stability.

Materials and Methods:

Fifty-two bone blocks were extracted from fresh bovine pelvic bone. Four groups were created based on bone type (iliac or pubic region) and presence or absence of cortical bone. Specimens were micro-computed tomography imaged to evaluate trabecular thickness, trabecular number, trabecular separation, bone volume density (BV/TV), BMD, and cortical thickness. Miniscrews 1.4 mm in diameter and 6 mm long were inserted into the bone blocks, and primary stability was evaluated by insertion torque (IT), mini-implant mobility (PTV), and pull-out strength (PS).

Results:

Intergroup comparison showed lower levels of primary stability when the BMD of trabecular bone was lower and in the absence of cortical bone (P ≤ .05). The Pearson correlation test showed correlation between trabecular number, trabecular thickness, BV/TV, trabecular BMD, total BMD, and IT, PTV, and PS. There was correlation between cortical thickness and IT and PS (P ≤ .05).

Conclusion:

Cancellous bone plays an important role in primary stability of mini-implants in the presence or absence of cortical bone.

Authors: Gdynia Adam
Published: November 2013

Presently, as a result of the technical progress, more and more complicated machines are being used in our everyday life. This is even more the case in relation to technology used at sea, where highly specialised services are needed. Sophisticated marine devices require special diagnostic methods that take into account the specific conditions of use of this type of machinery. In this paper we present the diagnostic systems elaborated to support the exploitation of the vessel power. Marine engine is a complex technical object. For the purpose of diagnostics it is convenient to divide the engine into several units - subsystems such as: piston -crank assembly; working medium exchange system, fuel supply system, lubricating system, cooling system, starting up - reversing system; combustion chamber, etc. The organization of the marine engine and auxiliary machinery diagnostic process can usually come down to two stages, general diagnostics and damage location. Most popular in marine engine diagnostics have been the periodic run analyzers, called pressure analyzers, electronic indicators. The diagnostic system of marine engine is able to assess the current engine condition and give forecast concerning its future operation in a complex way with the use of computer technology. Working out operating decision was based on proper preparation of operational parameters which were processed in a computer according to defined algorithms.

Published: November 2013

Town of Krosno is supplied with water by 3 intakes: Sieniawa, Iskrzynia and Szczepańcowa. After the treatment water flows in water mains to the water network in Krosno. The aim of his paper is qualitative risk analysis of the water main Sieniawa failures. The consequences of the failure: pressure value in the network and its duration, were described for different conditions of failures: time of failure, water demand and water storage tanks initial filling. For simulations of pipe failure water network model made in Epanet 2 program was used. The model was verified both during operation of water network and during the failure, where field data were used. The results of the simulations are corresponding to observations made during the real failures. Negative consequences appear only after emptying the water storage tanks, it results from two features of the storage tanks: they stabilize pressure in the network and for some time can provide water to the network. The time of emptying the storage tanks varies according to water demand their initial filling, it is at least 3 hours. During this time the are no sign of failure. When the storage tanks are empty reduction of pressure an shortage of water are observed on prevailing area of Krosno.

With regard to drinking water consumers, safety is understood as a probability to avoid threat arising from the consumption of water inconsistent with quality standards or the lack of water. Accordance with the Regulation of the Minister of Health water is safe for human health, if it is free from pathogenic microorganisms and parasites in the amount constituting a potential threat to human health, any substances in quantities hazardous to health and has no aggressive corrosive properties. Water supply reliability means providing stable conditions allowing to meet current and future demand for water in sufficient quantity and with required quality, in convenient time for water consumers and also at a price acceptable by them. In this study consumer (individual) risk rK was defined as the sum of the first kind of risk rKI, associated with possibility of interruptions in water supply and the second kind of risk rKII associated with possibility of consumption of water inconsistent with quality standards. Three-parameter matrix of risk was proposed. For presented method was made an application example based on exploitation data of collective water supply system, which may help to increase safety of water consumers.
The Multivariate Multilevel Analysis of Different Regional Factors Impact on Road Safety in European Country Regions / WIELOPOZIOMOWA ANALIZA WIELOCZYNNIKOWA WPŁYWU RÓŻNYCH CHARAKTERYSTYK REGIONALNYCH NA POZIOM BEZPIECZEŃSTWO RUCHU W REGIONACH KRAJÓW EUROPEJSKICH

Published: November 2013

In this research, the effect of the European regional differences on the risk of been killed in road accident in these regions is investigated. Factors which differentiate regions can be described as automotive, economic, infrastructural, demographic, geographic. Analyzed risk, counted as regional fatality rate was modeled by the Poisson model. Because of regional diversity of Poisson distribution parameters, the Poisson distribution was adopted. The multivariate multilevel model was developed, in order to asses combined effects of different factors on road safety level in regions. Such models could be helpful to forecast such risk on the regional level and focus safety actions precisely for region, because the national actions and their results differentiate in regions so far.

Published: November 2013

Safety of the transport process is a criterion of top priority for a transportation system operation and maintenance. It is of special importance in case of public municipal transportation. Systems of this type operate in specific road conditions: increased intensity of traffic during a day and night, a big number of pedestrians as well as drivers of other vehicles. In such conditions the human factor and its impact on the transport system operation is of key importance. A human can be involved in the transportation system as a driver, passenger, pedestrian, or in another way (cyclist, motorcyclist). Improper behavior of people account for 36% - 46% of road accident causes defined as undesirable events occurred within the space of the road. In this paper there has been mad an attempt to evaluate the transportation system from the point of view of people present in the transportation system and its environment.

Published: November 2013

This paper will review the different analysis scenarios that can be used when examining the reliability of repairable systems. Five different methods will be reviewed, specifically:

1) Using the mean value of the times between failure (TBFs) at the system level.

2) Using the distributions of the components of the system and creating a reliability block diagram (RBD).

3) Using the distribution of the times between failure (TBFs) at the system level.

4) Using the system level failure data and fitting the non-homogeneous Poisson process (NHPP) model.

5) Using the system level failure data and fitting the general renewal process (GRP) model.

In the paper, the five different methods will be discussed (brief background), and conclusions about the applicability and accuracy of each method will be given. In addition, this paper can be used to further understand the assumptions behind each analysis method, the data required and the type of results that can be obtained, thus assisting analysts in choosing the most appropriate method.
Network Systems Analysis in Case of Critical Situations
Authors: Mazurkiewicz Jacek
Published: November 2013

The paper describes the analysis and discussion of the network systems in case of the critical situation that happens during ordinary work. The formal model is proposed - based on the two types of real sophisticated network systems - with the approach to its modelling based on the system behaviour observation. The definition of the critical situation sets are created by reliability, functional and human reasons. No restriction on the system structure and on a kind of distribution describing the system functional and reliability parameters is the main advantage of the approach. The proposed solution seems to be essential for the owner and administrator of the transportation systems.
Simulation Based Performance of Mumbai-Pune Expressway Scenario for Vehicle-to-Vehicle Communication Using IEEE 802.11P
Authors: Khairnar Vaishali D. , Kotecha Ketan
Published: November 2013

Traffic safety applications using vehicle-to-vehicle (V2V) communication is an emerging technology and promising area within the ITS environment. Many of these applications require real-time communication with high reliability; to meet a real-time deadline, timely and predictable access to the channel. The medium access method used in 802.11p, CSMA with collision avoidance, does not guarantee channel access before a finite deadline. The well-known property of CSMA is undesirable for critical communications scenarios. The simulation results reveal that a specific vehicle is forced to drop over 80% of its packets because no channel access was possible before the next message was generated. To overcome this problem, we propose to use STDMA for realtime data traffic between vehicles. The real-time properties of STDMA are investigated by means of the highway road simulation scenario, with promising results.
Qur'anic Exegesis in Old Kanembu: Linguistic Precision for Better Interpretation
Authors: Bondarev Dmitry
Published: November 2013

The way the traditional Borno scholars represent Qur'anic Arabic in Old Kanembu testifies to their understanding of Arabic grammatical structures based on traditional grammatical treatises. The function of Old Kanembu is motivated by the grammatical module of tafsīr studies, which includes iʿrāb, ḥarf, naḥw and other related disciplines. However, the Borno ʿulamāʾ do not strictly adhere to Arabic linguistic theory and also exploit the distinctive linguistic properties of the Old Kanembu language. In its elaborated output form, tafsīr in Old Kanembu incorporates four explanatory levels: (a) morphosyntactic; (b) phrase by phrase / lexical; (c) sentential and (d) interpretative. Thus, it is built on two interrelated platforms: metalanguage (i.e. language designed for description of language) and exegesis (i.e. interpretation of the text). This combination makes Old Kanembu a very powerful ‘software’ with a solid foundation in the science of tafsīr, that allows its users to check their own knowledge of the Qur'an with the precision required by the Arabic grammatical sciences. In its basic grammatical format, Old Kanembu is a platform for the exegete who provides tafsīr in full format. Thus, Old Kanembu serves both grammatical and interpretative purposes perfectly.
‘Classical Hausa’ Glosses in a Nineteenth-Century Qur'anic Manuscript: A Case of ‘Translational Reading’ in Sudanic Africa?
Authors: Dobronravin Nikolay
Published: November 2013

This article presents an analysis of Hausa glosses in a nineteenth-century Qur'anic manuscript (C1688) from the library of the Institute of Oriental Manuscripts in St Petersburg, and argues that a systematic study of Arabic manuscripts with Hausa glosses is needed for a re-interpretation of early Hausa writings in Arabic script. The origins of the Hausa written tradition in Arabic script and the evolution of the concept ‘Ajami’ in the nineteenth and twentieth centuries from ‘non-Arabic (language, culture, etc.)’ to ‘a variety of Arabic script adapted to African languages (with additional vowel-signs and diacritics)’ is discussed, and it is suggested that the frequency of the marginal notes ʿajam and ʿajamī used to mark non-Arabic glosses in Arabic manuscripts might depend on the linguistic properties of the manuscripts as well as sub-regional traditions of writing in Sudanic Africa.

Hausa glosses in the St Petersburg manuscript – including nouns, adjectives, verbs and verbal constructions – are described in same detail. Special attention is paid to borrowings from Arabic and negative verbal constructions which are not attested in Hausa dialects and modern Standard Hausa. For the first time in Hausa studies, the shift in the meaning of the Hausa word shisshigi (from ‘acting tyrannically’ to ‘meddlesomeness’) is explored.

The glosses are compared with the Arabic text of Tafsīr al-Jalālayn and two modern Hausa tafāsīr, those of Abubakar Mahmud Gumi and Nasiru Kabara. It is demonstrated that the Hausa glosses in the St Petersburg Qur'anic MS share a greater affinity with Kabara's tafsīr than with Gumi's translation, and, on this basis, suggested that the translational practices reflected in the St Petersburg manuscript and in Kabara's tafsīr might be linked with the Qādiriyya tradition of Arabic-Hausa ‘translational reading’.

Un couvercle de sarcophage paléochrétien, vestige de la dévotion à saint Jean-Baptiste à l'abbaye de Saint-Denis
Authors: Lombard-Jourdan Anne
Published: November 2013

At the Maison d'Education de la Légion d'Honneur at Saint-Denis is a palaeochristian lid of a sarcophagus which has not been previously studied. It has been reused to cover an ossuary housing the bones of Bénédictine monks, exhumed during work on the cloister in the eighteenth Century and reburied in September 1886 in the cemetery of the Maison, next to the park.

The slab is eut prismatically in the form of a roof with four slopes, three of which are sculpted with round imbrications in the form of carp scales. It differs from other similarly sculpted lids dating from the early Middle Ages with respect to its material : a very hard pink and white veined marble, and with respect to an engraved inscription referring to the décollation of Saint John the Baptist, yet another witness to the ancient and often attested cuit of the Baptist at the abbey of Saint Denis.
Le château du Plessis-Belleville : François Mansart copie François Mansart
Authors: Mignot Claude
Published: November 2013

E. J. Ciprut hatte 1965 das Schloss von Plessis-Belleville auf die Jahre von 1627-1628 datiert und François Mansart zugeschrieben. Zwei unveröffentlichte Gutachten erlauben es, den genauen Plan aller fünf Geschosse dieses Jugendwerkes zu restituieren. Plessis-Belleville erscheint somit wie ein Zwillingsschloss von Balleroy, was die traditionnelle Datierug des Normannischen Schlosses bestätigt. In den Feuillants hatte Mansart, der seiner eigenen schöpferischen Möglichkeiten damals noch wenig sicher war, die Fassade des Salomon de Brosse von Saint-Gervais kopiert ; hier kopiert er sich selbst, indem er sich wiederholt.

Im Jahre 1656 wurde das Schloss durch den Bau von zwei grossen zusätzlichen Pavillons erweitert, was es erlaubte, die Treppe seitlich zu verschieben und in der Mitte Platz für einen grossen Saal nach italienischer Mode zu schaffen.
Le « Maître Nicolas d'Amiens » et la mise au tombeau de Malesherbes. À propos d'un document inédit
Authors: Grodecki Catherine
Published: November 2013

La Mise au tombeau de l'église de Malesherbes proviendrait, selon la tradition, de l'ancien couvent des Cordeliers, fondé en ce lieu en 1494 par l'amiral Louis Malet de Graville, détruit en 1802. En fait, un acte notarié nous apprend que le monument a été commandé le 28 mars 1495 par l'amiral de Graville pour la chapelle de son château de Malesherbes à un « tailleur d'images » résidant à Paris, mais probablement d'origine anversoise, Adrien Wincart, qui devait l'exécuter selon l'ordonnance et suivant le patron « fait par Maître Nicolas d'Amiens ». Une note dans le chartrier de Malesherbes confirme la situation première de la Mise au tombeau dans la chapelle castrale, dont elle fut enlevée pour être transportée au couvent des Cordeliers en 1720. Il est possible que le monument prenait place à l'origine dans la petite chapelle élevée dans son château à la fin du XVe siècle par l'amiral de Graville, dans un enfeu abrité sous une arcade flamboyante qu'on peut y voir encore. Récemment Mme Nicole Reynaud a proposé d'identifier l'ordonnateur du monument, Nicolas d'Amiens, dit « Colin d'Amiens », avec le « Maître de Coëtivy », peintre et enlumineur qui a peint de nombreux manuscrits, aussi peintre de tableaux, cartonnier de vitraux et de tapisseries, fournisseur de patrons d'orfèvrerie et de sculpture, dont celui du priant de Louis XI à Notre-Dame de Cléry (1482).

La comparaison des figures de Malesherbes avec des œuvres attribuées au « Maître de Coëtivy » (tableau de la Résurrection de Lazare au Louvre, vitraux de Saint- Séverin de Paris, patrons pour la tenture de la Guerre de Troie) conforte l'indication donnée par le marché et autorise, en s'appuyant sur l'hypothèse de Nicole Reynaud, à reconnaître dans le « Maître de Coëtivy », identifie avec Nicolas, dit Colin d'Amiens, le concepteur du monument. L'activité reconnue de l'artiste irait alors de 1450 environ à 1495.
Bidirectional cross metathesis and ring-closing metathesis/ring opening of a C2-symmetric building block: a strategy for the synthesis of decanolide natural products
Authors: Schmidt Bernd , Kunz Oliver
Published: November 2013

Starting from the conveniently available ex-chiral pool building block (R,R)-hexa-1,5-diene-3,4-diol, the ten-membered ring lactones stagonolide E and curvulide A were synthesized using a bidirectional olefin-metathesis functionalization of the terminal double bonds. Key steps are (i) a site-selective cross metathesis, (ii) a highly diastereoselective extended tethered RCM to furnish a (Z,E)-configured dienyl carboxylic acid and (iii) a Ru–lipase-catalyzed dynamic kinetic resolution to establish the desired configuration at C9. Ring closure was accomplished by macrolactonization. Curvulide A was synthesized from stagonolide E through Sharpless epoxidation.
Genetic and Genomic Analysis of the Tree Legume Pongamia pinnata as a Feedstock for Biofuels
Authors: Biswas Bandana , Kazakoff Stephen H. , Jiang Qunyi , Samuel Sharon , Gresshoff Peter M. , Scott Paul T.
Published: November 2013

The tree legume Pongamia {Pongamia pinnata (L.) Pierre [syn. Millettia pinnata (L.) Panigrahi]} is emerging as an important biofuels feedstock. It produces about 30 kg per tree per year of seeds, containing up to 55% oil (w/v), of which approximately 50% is oleic acid (C18:1). The capacity for biological N fixation places Pongamia in a more sustainable position than current nonlegume biofuel feedstocks. Also due to its drought and salinity tolerance, Pongamia can grow on marginal land not destined for production of food. As part of the effort to domesticate Pongamia our research group at The University of Queensland has started to develop specific genetic and genomic tools. Much of the preliminary work to date has focused on characterizing the genetic diversity of wild populations. This diversity is reflective of the outcrossing reproductive biology of Pongamia and necessitates the requirement to develop clonal propagation protocols. Both the chloroplast and mitochondrial genomes of Pongamia have been sequenced and annotated (152,968 and 425,718 bp, respectively), with similarities to previously characterized legume organelle genomes. Many nuclear genes associated with oil biosynthesis and nodulation in Pongamia have been characterized. The continued application of genetic and genomic tools will support the deployment of Pongamia as a sustainable biofuel feedstock.

Distributed Agent-based IP Location System Framework Design
Authors: Lin Feng-Yu , Sun Yeali S , Chen Meng Chang
Published: November 2013

Computer crime causes significant impact and

losses to society and the public security of countries, and

even influences homeland security. From previous lessons,

we know that the physical location of computer criminals

plays an important role in combat with computer crime,

including IP Traceback and IP Location. Literature review

shows that there have been many studies of the topic of IP

Traceback. However, the most critical IP Location has not

yet been thoroughly discussed, and existing IP Location

approaches, as based on end-to-end delay measurement

from a set of landmarks, fail to outperform much simpler

techniques, and the error of these approaches is strongly

determined by the distance to the nearest landmark, even

when triangulation is used to combine estimates from

different landmarks. In view of this, this study uses the

concept of IP Location and Network Forensics to propose

the distributed agent-based IP Location system framework

in order that the "position" of the criminal can be traced,

and identity can be deduced by this mechanism, when

cybercriminal behavior occurs. The result of actual

implementation in WiMAX networks shows that the

accuracy of IP Location can be the coverage area of a base

station (in radius of 150-500 m in urban areas).
Efficient Data Gathering in Wireless Sensor Networks Based on Matrix Completion and Compressive Sensing
Authors: Xiong Jiping , Zhao Jian , Chen Lei
Published: November 2013

Gathering data in an energy efficient manner in

wireless sensor networks is an important design challenge. In wireless sensor networks, the readings of sensors always exhibit intra-temporal and inter-spatial correlations. Therefore, in this paper, we use low rank matrix completion theory to explore the inter-spatial correlation and use compressive sensing theory to take advantage of intratemporal correlation. Our method, dubbed MCCS, can significantly reduce the amount of data that each sensor must send through network and to the sink, thus prolong the lifetime of the whole networks.

Taking the full network observability of power

system and the least number of PMU as objective, to

appearing fault situation in the grid, this paper proposes

Differential Evolution and Particle Swarm Optimization

(DEPSO) algorithm in view of the system failure rate. The

improved DEPSO algorithm is global optimization, the

algorithm takes the constraint condition of fault rate into

account during the course of seeking optimal solutions. At

the end, through the examples show that the algorithm

compares with the existing optimization methods, which can

reduce the number of PMU configuration and achieve

completely observability of the system, at the same time, and

stable operation of the system, through the simulation

results verify feasibility and valibity of the algorithm.

Published: November 2013

Based on the analysis of urban traffic flow affected by bus lane, a two-lane cellular automata model is established under the periodic boundary condition. The properties of traffic flow are investigated by analyzing the velocity-density and flow-density diagrams. The spatial-temporal diagrams with the two types of bus stop facilities are also discussed. Simulated results show that the bus lane can significantly improve the traffic flow , and the volume can increased by extending the bus stop length, and the bus stop with no overtaking facilities has less volume than the bus stop to permit overtaking.

This paper addresses network performance evaluation for the Internet of Things. There are a wide variety of networks at the bottom layer of the Internet of Things, such as wireless sensor network, ad hoc network. Therefore, it is not easy for the Internet of Things to evaluate its network performance. For the heterogeneity of the Internet of Things, this paper proposes an application-oriented network performance evaluation model. This model combines the qualitative and quantitative evaluation method, giving the four levels of network performance firstly, and proposes a new network performance evaluation indicator, which is cumulative network performance evaluation value. In this model, it gives the qualitative and quantitative analysis for the performance of the Internet of Things at the application layer, and determines the level of network performance, then calculates the network performance evaluation value and the cumulative network performance evaluation value. By analyzing the network operating data collected, the experimental results show that the network performance level and the two network performance values characterize the status of the Internet of Things accurately. These evaluation results can provide basis for decision making to optimize network configuration and improve network performance.
Architecture Leadership and Systems Thinking
Authors: Krishnamurthy Raghuraman
Published: November 2013

Gone are the days when organizations were concerned with increasing efficiency by mastering repetitive tasks. The competitive, boundary-less world of today has dramatically altered the primary challenges of an organization: fluidity, coherence, and connectedness are the hallmarks of successful organizations. Concomitant with this epochal transformation is the emergence of information systems as the backbone for conducting any business. Today, one cannot find any enterprise or government that is not permeated by information systems at all levels. That the role of information systems is so central to any organization is evident from the prescient words of management legend, Peter Drucker, that the future CEO may be the CIO. With extended enterprises so very common, how do we not lose sight at the bigger picture while making decisions? Systems thinking advocates cultivation of viewing the “whole” and seeing the parts (of the whole) in the context of dependence with other parts (of the whole) and their interactions. Architecture should help create necessary artifacts to understand and manage the complexities. Developing insights on how things work together and the influence of one part over the other is at the heart of architectural conversations. There is thus a natural connect between leadership, architecture, and systems thinking. This chapter explores the nature of evolving enterprises and the increasing relevance of systems thinking in architectural activities. The author discusses the importance of systems thinking to enterprise architecture and illustrate, with TOGAF as an example, how to apply the principles of systems thinking. A conceptual case study is presented to illustrate the application of systems thinking in architectural governance.
Navigating Complexity with Enterprise Architecture Management
Authors: Luo Haiping
Published: November 2013

Enterprises are like living creatures in the ecosystem – there are vast varieties of species; each individual in any species is unique, complex, dynamic, and constantly interacting with its ever-changing environment. Also, like living creatures, enterprises have many commonalities. These commonalities exist in all enterprises, regardless of their business, size, environment, culture, lifecycle stage, or any other factor. Enterprise Architecture (EA) management helps enterprises discover their commonalities, adopt best practices to manage the commonalities, and apply holistic and systemic approaches to tackling unique complexity encountered by enterprises. This chapter extracts thinking from many thought leaders in the EA discipline and consolidates a dynamic and multi-dimensional alignment approach to managing an enterprise’s architecture as a living system. This integrated approach utilizes the “Fractal” concept in Chaos Theory and identifies six common alignment dimensions in enterprises. This approach includes dynamic alignment mechanisms to help enterprises navigate the increasingly complex and ever-changing world. This approach bridges individual alignments with enterprise optimization. A fictional example of a disaster relief operation is used to illustrate how the EA approach could help a relief enterprise navigate through the complexity and dynamics of the disaster relief operation to achieve life-saving results.
Enterprise Architecture’s Identity Crisis
Authors: Taylor Paul R.
Published: November 2013

This chapter outlines the rational foundations of the enterprise architecture discipline to date and describes ways and situations in which the traditional approaches of enterprise architecture fail to account for a number of contemporary market and economic situations and organizational behaviors. It characterizes new methods and approaches loosely based on systems thinking, with examples from the Australian e-government experience, and argues that the discipline must re-invent itself to incorporate a post-rational perspective to stay relevant. The chapter concludes with narratives of how the new enterprise architecture must engage with business to stay relevant over the next decade and beyond.
The Role of Payments for Ecological Services in the Sustainable Development and Environmental Preservation of the Rainforest

The county of Barcelos in the state of Amazonas, Brazil comprises 122 thousand square kilometers of land, composed of the rainforest, rivers and lakes of the middle Rio Negro watershed. The area is virtually free of deforestation and blessed with abundant fishery resources. It is widely regarded to be the best freshwater fishing location in the world and until recently was regarded as one of the global centers of the aquarium fish trade. Unfortunately, a variety of factors have kept the human population of this immense region from benefiting from these abundant natural resources. This paper outlines a path towards sustainable development of these resources that we developed in conjunction with the government of Barcelos, fishermen’s cooperatives, and indigenous associations. The paper illustrates how a payment for environmental services can jump start sustainable development in a pristine area and illustrate some of the factors that can impede such a system. Most discussion of payment for environmental services focuses on how such a payment can prevent deterioration of an area under current threat. The goal is to improve the quality of life of the citizens of the area in a way that eliminates future potential threats to the ecological integrity of the complex aquatic/terrestrial ecosystem. In addition to the development of human capital, a fishery and ecotourism management plan is developed that uses the revenue from the environmental tax to solve infrastructure, human capital and social capital needs. Although the official program of payment for environmental services was halted for local political reasons, the authors are in the process of establishing a voluntary program of payment for environmental services which will accomplish the same objectives.

The main objective of this article is to analyse the development of Amazon region through biotechnological activities. Amazonia, by virtue of its tremendous biodiversity, has excellent possibilities of meeting a growing market for biotechnological products, being that the development of this sector demands not only abundant natural resources, but also the existence of an institutional environment that is able to integrate productive activities with research on science and technology. The promotion of regional development, thus, depends on the configuration, which, according to Boisier, is composed by six elements, present in all regions that interact with each other. The article concludes that Amazonian development is directly related to the participation capability of many segments of society for the development of biotechnological activities, in which the State should play an important role in drawing up policies towards the biotechnological sector and, at the same time, in setting up participation channels for the relationship among actors.
Krimpsiekte in South Africa: Historical perspectives
Authors: Botha Christo J.
Published: November 2013

Krimpsiekte, also known as cotyledonosis or nentain sheep and goats, has been recognised as a disease entity since 1775. However, it was only in 1891 that Veterinary Surgeon Soga reproduced the condition by dosing Cotyledon (= Tylecodon) ventricosus leaves to goats. Professor MacOwan, a botanist, confirmed the identity of these nenta plants. From a South African veterinary toxicological point of view the date 1891 is of considerable historical significance as this was the first time that a plant was experimentally demonstrated to be toxic to livestock in South Africa. A chronological account of the history of krimpsiekte research is provided.
Overview of the developments in the domestic airline industry in South Africa since market deregulation
Authors: Luke Rose , Walters Jackie
Published: November 2013

Deregulation or liberalisation of air transport has had major global impacts on the domestic air transport markets, with effects ranging from stimulation to changes in the structure and functioning of these markets. In South Africa, deregulation has had wide-reaching effects on the domestic market. The purpose of this article was to investigate the current domestic air transport market. A literature review was performed to examine the effects of deregulation in other domestic air transport markets around the world. This was followed by a review of the South African domestic air transport market prior to deregulation in order to determine the changes that were made following deregulation. The ten-year period immediately following deregulation was also examined; this period was characterised by relatively large numbers of market entries and exits. A database was obtained from the Airports Company South Africa; air traffic movements, passenger numbers and load factors were evaluated. The study showed that the market is still characterised by regular market entries and exits. Also that the entry of the low-cost carriers has stimulated the market, resulting in increased air traffic movements, higher passenger numbers, higher load factors in general and the opening of a secondary airport in Gauteng, Lanseria International. Deregulation and, more specifically, the entry of the low-cost carriers has resulted in structural changes in the market and more choice for passengers.
