Compost versus vermicompost as substrate constituents for rooting shrub cuttings

The feasibility of composted (C), composted plus vermicomposted (V1) and straight vermicomposted (V2) tomato crop waste as component of rooting media for Euonymus japonicus �Microphylla� and Lavandula angustifolia vegetative propagation was studied. Mixes of C, V1 and V2 with coir fibre (CF) at the proportions 100:0, 75:25, 50:50, 25:75, 0:100 (v:v) were assayed. Physical, physico-chemical and nutritional characteristics of all materials and mixes were determined and correlated with cutting rooting and growth performances. The compost and the two vermicomposts were markedly different from CF. They had higher bulk density and lower total porosity than CF. Compost had lower water-holding capacity and shrinkage in response to drying than vermicomposts and CF. Compost and vermicomposts were alkaline materials whilst CF was almost neutral. Electrical conductivity (EC) was low in CF and vermicomposts, and high in compost due to the high mineral contents, mainly of K+, SO4 2� and Na+ in this material. EC and the ions contributing to it (K+, SO4 2�, Na+) showed highly significative inverse correlations with rooting percentage for the two species and with root and shoot growth but only for E. japonicus. Due to its high EC, compost C (average rooting = 22.5%) performed worse than vermicomposts V1 (av. rooting = 97%) and V2 (av. rooting = 98%) whilst the latter performed similarly to CF control (av. rooting = 100%). Thus vermicomposts appeared to be more appropriate than compost as rooting media constituent.
Multi Spectral Band Selective Coding for Medical Image Compression

Medical image compression has recently evolved as an area of research for progressive transmission. The distance based medical diagnosis, demands for high quality imaging at faster data transfer rate. As the information’s are highly informative, each pixel information defines a sample observation. Hence the coding in medical diagnosis need to be of higher accuracy than conventional image coding. In the approach of image coding multi spectral coding is developed as new coding approach to achieve the objective of higher visualization accuracy. With this observation in this paper a multi spectral coding using multi wavelet transformation is developed. The multi spectral coding is improved by a band selective approach using inter band correlation factor. The evaluation factors for such a coding technique are observed to be improved over conventional multi-spectral coding.
Digital Control For Power Management Systems

The present document aims to show the advantages of a digital implementation of the regulation(s) used for the control of DC/DC converters. In a first step, a general overview of the capabilities provided by digital solution, w.r. t. analogue, will be introduced. An example of a pure digital algorithm (the predictive programmed current control) will also be presented. In a second step, a practical application of a digital control will be considered. In this example, the output voltage of two Buck DC/DCs, connected in parallel, is controlled via a digital regulation. This application also integrates different possible features (soft start, current sharing, embedded scope…), easy to implement in digital, and whose analogue equivalent would be hard or impossible to obtain. Finally, a quick overview of the radiation-hardened ASIC developed by Thales Alenia Space will be given. This component, called “Digital Programmable Controller” (DPC) is totally suitable to implement digital regulations for space applications.
Leadership of Global Information Technology Projects

The goal of this literature review is to evaluate the cultural variables critical to successful leadership of a global information technology project. Also to analyze the fundamental challenges to today's IT projects. To properly evaluate variables critical to successful leadership, a thorough investigation must be made of the leader, which in most cases will be the CIO or IT Manager. Technology acceptance is the concept of how end users accept and therefore use technology and is a key cultural variable critical to success. The concept of technology acceptance is very important and applies to a wide scope of users including both personal and business end users, IT employees and managers, and business executives. Jiun-Sheng and Hsing-Chi (2011) write, "Consumers' adoption of new information technology has been a central concern to many researchers and practitioners owing to its importance in technology diffusion. " (p. 424).
Monitoring seismic velocity change caused by the 2011 Tohoku‐oki earthquake using ambient noise records

We estimated the changes in seismic velocity in the southern Tohoku district of Japan during the six‐month period centered on the 11 March 2011 Tohoku‐oki earthquake, using scattered waves retrieved by autocorrelation of ambient seismic noise. The estimated velocity decrease after the earthquake, and after two large aftershocks in the study area, was as great as 1.5% in the area nearest to the mainshock. The velocity changes displayed gradual healing. The spatial distribution of the velocity change showed a correlation with both the changes in static strain, derived from GPS records, and the peak particle velocity experienced during the three earthquakes, derived from strong‐motion records. Therefore, our results show that velocity changes possibly contain information from deep in the crust bearing on coseismic stress release, in addition to shallower effects due to strong ground motion.
FORAGE SPECIES USED BY LİVESTOCK İN THE KUMBUNGU DİSTRICT OF THE NORTHERN REGİON, GHANA

Livestock production in the Northern Region is a major activity in the livelihoods of the population and contributes greatly to income generation in the region. The annual growth rate of free ranging ruminants is limited by forage quality and quantity especially during the dry season. This study was carried out to identify the grass/forbs and browse species used to feed livestock, rank the identified grasses/forbs and browse species in order of preference by livestock and to identify the parts of the browse mostly eaten by the animals. Ten communities were randomly selected from the study area for the research. Personal observation and questionnaire administration were employed to collect the data. In all, one hundred respondents were interviewed. Twenty-seven (27) grasses/forbs and thirty-two (32) browse species were identified. Setaria pallide fusca was the most preferred grass species whiles Securinega virosa was the most preferred browse species by the livestock in the study area. The study also revealed that livestock farmers currently travel longer distances (over 4km) to harvest these species. The large number of forage species being used indicate that the study area is rich in grasses/forbs and browse species. However, there is a threat to these species due to annual bush fires. Therefore, livestock farmers should incorporate forage cultivation into their annual crop farming systems to supplement the feeding of their animals.
Transition behavior of mental load and performance when automation level changes

Human performance and mental load are investigated during a transition from a normal to an abnormal situation. The abnormal situation is simulated by a sudden loss of the automatic control of a task which is interpreted as a sudden drop in the degree of automation, DofA. The mental load perceived by the Operators becomes higher due to the sudden drop of the DofA, and arrives at a peak shortly after the drop. The mental load will decrease to a low level a long period after the drop. This low level may be perceived if the Operators statt to operate the System at that low value of DofA. Right after the DofA drops, human performance drops considerably. As time progresses the performance recovers to a level that would have been found in a situation that the System is operated at the same low value of the DofA.

Plant entry in a more liberalised industrialisation process: an experience of Indonesian manufacturing during the 1990s

Some major policy changes towards a more open trade and investment regime occurred in Indonesia during the 1980s and 1990s. The impact of these policy changes on the country's industrialisation has been generally favourable. However, little is known about the impact on the dynamics of plant in the country's manufacturing. This study addresses this subject, examining the extent and determinants of plant entry in Indonesian manufacturing over the period 1993-96, and asking how the policy reforms affected plant entry. The key finding suggests that the policy reforms increased the extent of competition within industry. This, however, does not seem to be very strong, and the study puts forward some possible explanations. The discussion reaches a consensus that maybe, during the period under this study, the process of the reform had not really been completed and, at the same time, the (predicted) positive impact of the liberalisation had not been fully realised.
HIGH EFFICIENCY BRIDGELESS PWM CUK CONVERTER WITH SOFT SWITCHING TECHNIQUE

High efficiency bridgeless single-phase ac-dc PWM cuk converter with soft-switching (ZVS) technique is proposed. This paper emphasizes more on the converter efficiency. The conduction losses and input current harmonics of the proposed converter is very less due to the absence of the input diode bridge and also during each switching cycle, only two semiconductor switches are present in the current path unlike other conventional Cuk converters. Soft switching (ZVS) technique is applied by using an auxiliary circuit to improve the efficiency of the proposed converter. Output voltage regulating control technique is provided to regulate the output which also ultimately improves the efficiency. Power factor is almost unity due to less input current harmonics. The circuit configuration, principle of operation, design procedure and simulation results are presented. Keywords-Bridgeless, Cuk converter, Power factor correction (PFC), Rectifier, Soft switching.
Dual-Tree Complex Wavelet Packet Transform and Feature Selection Techniques for Infant Cry Classification

A Dual-Tree Complex Wavelet Packet Transform (DT-CWPT) feature extraction has been used in infant cry signal classification to extract the feature. Total of 124 energy features and 124 Shannon entropy features were extracted from each sub-band after five level decomposition by DT-CWPT. Feature selection techniques used to deal with massive information obtained from DT-CWPT extraction. The feature selection techniques reduced the number of features by select and form feature subset for classification phase. ELM classifier with 10-fold cross-validation scheme was used to classify the infant cry signal. Three experiments were conducted with different feature sets for three binary classification problems (Asphyxia versus Normal, Deaf versus Normal, and Hunger versus Pain). The results reported that features selection techniques reduced the number of features and achieved high accuracy.
The Entanglement Hierarchy of 2 × m × n Systems

M. Hebenstreit, M. Gachechiladze, O. Gühne, and B. Kraus Institute for Theoretical Physics, University of Innsbruck, Technikerstr. 21A, 6020 Innsbruck, Austria Naturwissenschaftlich-Technische Fakultät, Universität Siegen, Walter-Flex-Str. 3, 57068 Siegen, Germany We consider three-partite pure states in the Hilbert space C ⊗ C ⊗ C and investigate to which states a given state can be locally transformed with a non-vanishing probability. Whenever the initial and final states are elements of the same Hilbert space, the problem can be solved via the characterization of the entanglement classes which are determined via stochastic operations and classical communication (SLOCC). In general, there are infinitely many SLOCC classes. However, when considering transformations from higherto lower-dimensional Hilbert spaces, an additional hierarchy among the classes can be found. This hierarchy of SLOCC classes coarse grains SLOCC classes which can be reached from a common resource state of higher dimension. We first show that a generic set of states in C ⊗C ⊗C for n = m is the union of infinitely many SLOCC classes, which can be parameterized by m− 3 parameters. However, for n 6= m there exists a single SLOCC class which is generic. Using this result, we then show that there is a full-measure set of states in
Diversity patterns of stygobiotic crustaceans across multiple spatial scales in Europe

SUMMARY 1. Using species distribution data from 111 aquifers distributed in nine European regions, we examined the pairwise relationships between local species richness (LSR), dissimilarity in species composition among localities, and regional species richness (RSR). In addition, we quantified the relative contribution of three nested spatial units – aquifers, catchments and regions – to the overall richness of groundwater crustaceans. 2. The average number of species in karst and porous aquifers (LSR) varied significantly among regions and was dependent upon the richness of the regional species pool (RSR). LSR–RSR relationships differed between habitats: species richness in karstic local communities increased linearly with richness of the surrounding region, whereas that of porous local communities levelled off beyond a certain value of RSR. 3. Dissimilarity in species composition among aquifers of a region increased significantly with increasing regional richness because of stronger habitat specialisation and a decrease in the geographic range of species among karst aquifers. Species turnover among karst aquifers was positively related to RSR, whereas this relationship was not significant for porous aquifers. 4. The contribution of a given spatial unit to total richness increased as size of the spatial unit increased, although 72% of the overall richness was attributed to among-region diversity. Differences in community composition between similar habitats in different regions were typically more pronounced than between nearby communities from different habitats. 5. We conclude by calling for biodiversity assessment methods and conservation strategies that explicitly integrate the importance of turnover in community composition and habitat dissimilarity at multiple spatial scales.
Application of Fuzzy Logic Power Control for Cognitive Radio Networks

In this chapter, the authors present the application of fuzzy logic for power control in spectrum sharing cognitive radio network. The investigated network consists of a pair of primary users (PUs) and a pair of cognitive radio users (CRs). In order to compute an optimal power scale for the CR link, a fuzzybased optimal power control strategy is investigated based on the Mamdani fuzzy control model using two input variables: the PU’s signal-to-noise ratio (SNR) and PU’s interference channel gain (channel gain from the cognitive radio users to primary users). Applying the fuzzy-based optimal power control strategy, the desired quality of service (QoS) is assured on the PU link, and the efficiency of spectrum usage is also maximized on the CR link in the spectrum sharing network. In addition, the bit error rate (BER) is also improved as compared with the spectrum sharing network without power control. DOI: 10.4018/978-1-4666-2005-6.ch006
FINE PARTICLE MASS, NUMBER, SURFACE AREA CONCENTRATIONMETRICS AND THEIR CORRELATION IN OUTDOOR ENVIRONMENTS

Exposure to fine particles is measured using metrics such as mass concentration (MC), number concentration (NC) and surface area concentration (SAC). This study aims to find correlation between the three metrics in outdoor environments of a city – city periphery, city centre and on-road. Simultaneous real-time mass, number and surface area concentration measurements were conducted in these environments. Arithmetic means, peak concentration values, and regression coefficients were determined to find relation between the three metrics. Results indicate remarkable high indoor number, mass and surface area concentrations. For ambient sampling sites, good correlation coefficient r2=0.80 between MC and NC, and r2=0.69 between NC and SAC metrics were observed. However, traffic-influenced onroad measurements showed little weaker correlations of r2=0.45 and r2=0.30 respectively.

In addition, the wrapper has high multipurpose, realizing the domain adaptation extraction. The result of experiment indicates our method can improve the accuracy of extraction in various fields.
Optimal Impact Angle Guidance for Exoatmospheric Interception Utilizing Gravitational Effect

This paper aims to develop a new optimal intercept angle guidance law for exoatmospheric interception by utilizing gravity. A finite-time optimal regulation problem is formulated by considering the instantaneous zero-effort-miss and the intercept angle error as the system states. The analytical guidance command is then derived based on Schwarz's inequality approach and Lagrange multiplier concept. Capturability analysis using instantaneous linear time-invariant system concept is also presented to provide better insights of the proposed guidance law. Theoretical analysis reveals that the proposed optimal guidance law encompasses previously suggested optimal impact angle constrained guidance laws. Numerical simulations with some comparisons clearly demonstrate the effectiveness of the proposed guidance law.
Simulating the dynamic response of a photovoltaic generation system to voltage sags

Photovoltaic generation systems are usually low-power sources connected to the distribution network. As solar modules represent a voltage (current) dc-source, they must be connected to the grid through an electronic power converter producing low-distortion ac current. Utility distribution systems were not designed for accommodating power generation especially not during system disturbances. Because the converter's operation is highly dependent on the voltage at the point of connection the interaction between the network and such generation system should be analysed. In this paper the behaviour of a photovoltaic generation system in case of distribution network voltage sags is investigated by means of digital simulation.
Participatory Interface Design for Expert Users

The purpose of this project was to investigate if participatory design is suitable when designing for expert users. The project was executed at Findwise, a company that works in the field of enterprise search. The design for an administrator interface for Hydra, a tool that manages document processing pipelines intended for in-house usage, was developed. The future users of Hydra were highly involved in the design process to take advantage of their knowledge and experience. At first their current work situation was analyzed by interviews and observations. Then ideas for the new interface were generated during participatory workshops. The best ideas were then translated in to sketches and prototypes that were tested and evaluated through paper prototyping and discussions in iterations. The work resulted in a list of requirements for the interface and a design proposal in the shape of wireframes that was intended to meet these requirements. It turned out that the design ideas the users liked the most were transparent and very close to the implementation model of Hydra, which follows the guidelines for design for experts. During the development the users expressed valuable ideas and gave input that a person without their experience would not have been able to provide. Most of the users found it hard to discuss innovative ideas since they tended to focus on implementation matters, which sometimes inhibited the creativity. This indicates that a participatory design approach did contribute to a good design, but the structure of the participatory activities must encourage the creativity if more innovative solutions should be developed by expert users. Based on the feedback from the users and stakeholders regarding the final design, they are satisfied with the result. To establish this, the interface has to be further developed into a prototype that handles real data and then be tested in an actual work situation.
The influence of habitat heterogeneity on the fine-scale pattern of an Heteroptera assemblage in a sand grassland

The influence of elevation and vegetation characteristics on the spatial pattern of an epigeic true bug assemblage was investigated along a transect in a sandy grassland of Kiskunsag. A 55 m long transect through wind grooves and dune tops, perpendicular to the vegetation borders was established. Both the moving split window technique and the ordination method revealed that dune top habitat has a distinct Heteroptera assemblage. This sand dune habitat was characterized by the most abundant Heteroptera species. We did not observe a distinct true bug assemblage in the wind groove habitat. Canonical correspondence analysis and multiple linear regressions showed that the relative altitude had a greater effect on the distribution of true bugs than vegetation cover and plant species richness.
Income Effects and Physician Labour Supply: Evidence from the Threshold System in Ontario

We examine a reform to the physician threshold system in Ontario that provides a unique opportunity to assess the effect of fee changes on physician behaviour, free from the biases that potentially affect simple time-series or cross-section inference. We find that: (1) the income effects of fee changes are small, but significant; (2) the income effect dominates the substitution effect only for a minority of services with relatively low prices and high volumes; and (3) the cross effects of fee changes tend to be significant only for services with relatively high prices and low volumes.
A Framework of IS/Business Alignment Management Practices to Improve the Design of IT Governance Architectures

This research aims to identify specific management practices that can help to improve the process of IS/business alignment and the design of ITG architecture that supports those processes. To this end the authors propose a framework that is used as a reference to classify relevant management practices in the process of IS/business alignment and design of ITG architectures. The analysis was carried out in a large leading international food and beverage company. Findings show that at operational and tactical levels, improving the coordination of the IT investment management process and enabling structures that strengthen the connection of budgetary controls are core structural capabilities that can positively improve the process of IS/business alignment and impact significantly the design of ITG architectures.
