Operations & Maintenance Business Model Transformation—Multiple Case Studies

Capital goods companies’ service offering has been mainly to provide spare parts and maintenance work. In search of growth, these companies have expanded to new areas, such as Operations & Maintenance. Instead of operating and maintaining e.g. production processes itself, a customer can outsource a wide variety of managed services based on agreed service levels. There has been a special focus on global information management know-how, governance, process know-how, physical assets, and spare and wear parts. In order to get a good coverage of case studies, we selected five large global suppliers and two customer companies in telecommunication, energy, mining, and pulp and paper business. By implementing the right capabilities in information man- agement and human resources, by managing contract through governance models and by offering right products, a traditional company can transform to the Operations & Maintenance busi- ness model.
Cryptanalytic Performance Appraisal of Improved CCH2 Proxy Multisignature Scheme

Many of the signature schemes are proposed in which the out of threshold schemes are deployed, but they still lack the property of security. In this paper, we have discussed implementation of improved CCH1 and improved CCH2 proxy multisignature scheme based on elliptic curve cryptosystem. We have represented time complexity, space complexity, and computational overhead of improved CCH1 and CCH2 proxy multisignature schemes. We have presented cryptanalysis of improved CCH2 proxy multisignature scheme and showed that improved CCH2 scheme suffered from various attacks, that is, forgery attack and framing attack.
Studies on the optical band gap and cluster size of the polyaniline thin films irradiated with swift heavy Si ions

Polyaniline thin films prepared by RF plasma polymerisation were irradiated with 92MeV Si ions for various fluences of 1 10, 1 10 and 1 10 ions/cm. FTIR and UV–vis–NIR measurements were carried out on the pristine and Si ion irradiated polyaniline thin films for structural evaluation and optical band gap determination. The effect of swift heavy ions on the structural and optical properties of plasma-polymerised aniline thin film is investigated. Their properties are compared with that of the pristine sample. The FTIR spectrum indicates that the structure of the irradiated sample is altered. The optical studies show that the band gap of irradiated thin film has been considerably modified. This has been attributed to the rearrangement in the ring structure and the formation of CRC terminals. This results in extended conjugated structure causing reduction in optical band gap. r 2007 Elsevier Ltd. All rights reserved.
Sequential Generation of Singing F0 Contours from Musical Note Sequences Based on WaveNet

This paper describes a method that can generate a continuous F0 contour of a singing voice from a monophonic sequence of musical notes (musical score) by using a deep neural autoregressive model called WaveNet. Real F0 contours include complicated temporal and frequency fluctuations caused by singing expressions such as vibrato and portamento. Although explicit models such as hidden Markov models (HMMs) have often used for representing the F0 dynamics, it is difficult to generate realistic F0 contours due to the poor representation capability of such models. To overcome this limitation, WaveNet, which was invented for modeling raw waveforms in an unsupervised manner, was recently used for generating singing F0 contours from a musical score with lyrics in a supervised manner. Inspired by this attempt, we investigate the capability of WaveNet for generating singing F0 contours without using lyric information. Our method conditions WaveNet on pitch and contextual features of a musical score. As a loss function that is more suitable for generating F0 contours, we adopted the modified cross-entropy loss weighted with the square error between target and output F0s on the log-frequency axis. The experimental results show that these techniques improve the quality of generated F0 contours.
A novel restricted-flow etching method for glass

This paper presents a novel micro fabrication method based on the laminar characteristics of micro-scale flows. Therein the separator and etchant are alternatively arranged in micro channels to form multiple laminar streams, and the etchant is located at the site where the reaction is supposed to occur. This new micro fabrication process can be used for the high aspect ratio etching inside a microchannel on glass substrates. Furthermore, the topography of microstructure patterned by this method can be controlled by changing the flow parameters of the separator and etchant. Experiments on the effects of flow parameters on the aspect ratio, side wall profile and etching rate were carried out on a glass substrate. The effect of flow rates on the etching rate and the micro topography was analyzed. In addition, experiments with dynamical changes of the flow rate ratio of the separator and etchant showed that the verticality of the side walls of microstructures can be significantly improved. The restricted flowing etching technique not only abates the isotropic effect in the traditional wet etching but also significantly reduces the dependence on expensive photolithographic equipment.
CHANGES IN THE CELL GROWTH LIPID CONTENT AND LIPID PROFILE OF CHLORELLA PROTOTHECOIDES UNDER DIFFERENT MEDIUMS

Chlorella protothecoides is a precious lipid source that can be used as a biodiesel feedstock. Calcium, carbon, iron, hydrogen, magnesium, nitrogen, oxygen, phosphorus, potassium and sulfur are among the various elements have to be supplied for the growth of microalgae. Especially, nitrogen and phosphorus have significance in handling the growth ratio and lipid production of microalgae. In this study, the effect of different mediums (with/without nitrogen) on cell growth and lipid content of Chlorella protothecoides was investigated. Highest lipid extraction efficiency was obtained by using hexane at ambient temperature. The maximum lipid content of Chlorella protothecoides fed with the nitrogen free Bold Basal medium was 48% (dry weight percent). The composition of fatty acid methyl esters was influenced by alteration of medium.
Motivation in Words: Promotion- and Prevention-Oriented Leader Communication in Times of Crisis

Research demonstrates that situational uncertainty or crisis strongly influences the endorsement of the more charismatic or decisive leadership styles and that inspirational communication is at the heart of these styles. However, there is currently little understanding of what leaders should convey through their communication to be endorsed in crisis. Based on regulatory focus theory, we argue that times of crisis make leaders who use more promotion-oriented communication more likely to be endorsed and leaders who use more prevention-oriented communication less likely to be endorsed. Results of Study 1, an archival study of U.S. presidents, show that presidents who use more promotion-oriented communication are more endorsed but only if economic growth is low or if inflation is high, while no effects of the use of prevention orientation of communication surfaces. Results of Study 2, a laboratory experiment, show that leaders who communicate a promotion orientation, as compared to a prevention orientation, motivate higher performance in participants in a crisis condition, but that there is no difference in a no-crisis (i.e. control) condition. Finally, results of Study 3, a scenario experiment, demonstrate that organizational leaders that communicate more promotion-oriented (as opposed to more prevention-oriented) have a higher chance of being endorsed but only in times of crisis and that this effect is mediated by followers’ motivation to realize the plans of the leader.
Argument Mining on Clinical Trials 1

Argument-based decision making has been employed to support a variety of reasoning tasks over medical knowledge. These include evidence-based jus-tiﬁcations of the effects of treatments, the detection of conﬂicts in the knowledge base, and the enabling of uncertain and defeasible reasoning in the health-care sector. However, a common limitation of these approaches is that they rely on structured input information. Recent advances in argument mining have shown increasingly accurate results in detecting argument components and predicting their relations from unstructured, natural language texts. In this study, we discuss evidence and claim detection from Randomized Clinical Trials. To this end, we create a new annotated dataset about four different diseases (glaucoma, diabetes, hepatitis B, and hypertension), containing 976 argument components (697 containing evidence, 279 claims). Empirical results are promising, and show the portability of the proposed approach over different branches of medicine.
INTERNAL ELECTROSTATIC TRANSDUCTION FOR BULK-MODE MEMS RESONATORS

This paper demonstrates a new approach to electrostatic drive and detection of bulk acoustic resonators in which the electrode-gaps are filled with a high dielectric constant material. Internal electrostatic transduction has much higher efficiency than air-gap electrostatic transduction for bulk-mode resonators, which results in improved electrical performance. As a proof-of-concept, we demonstrate this phenomenon by electrostatic actuation of a 1.9GHz AlN (N ~ 9) film bulk acoustic resonator (FBAR).
Instant Messaging : Gratifications and Social Presence

This paper explores the Instant Messaging phenomenon within the college sector—the first generation to grow up with the Internet. Drawing on the uses and gratifications approach and social presence theory, a survey of 443 IM users reveals five gratifications sought and obtained: social utility, interpersonal utility, convenience, entertainment/relaxation and information. The results also demonstrate the important role of social presence in IM use. The value of integrating social presence into the uses and gratifications paradigm and other theoretical and practical implications are discussed. Keywords--Instant messaging; social presence; uses and gratifications.
OWNERSHIP STRUCTURE AND DEBT POLICY OF TUNISIAN FIRMS

The relation between corporate governance and the financial decisions presents a rich subject but less pronounced in corporate finance. The purpose of this article is to study the impact of the ownership structure on the debt policy of the Tunisian companies. From the econometric tests applied to Tunisian data of panel, the results obtained corroborate the assumptions of the entrenchment theory. The ownership structure is unable to orient the management of the leaders towards the maximization of the shareholders' richness. The companies with concentrated property don't use the debt like mean to encourage the leader to act according to their interests. The remuneration system does not encourage the leaders to privilege the financing of the investments by debt. The presence of the financial institutions in the capital of the Tunisian companies does not influence the policy of financing of the company. They don't exert a particular role of control on the management of the leaders in place by the debt.
Effect of high iron concentrations on iron uptake and growth of a coastal diatom Chaetoceros sociale

The growth and iron uptake of the coastal marine diatom Chaetoceros sociale were experimentally measured in batch experiments at 10°C to which an acidic Fe(III) stock solution was added. The direct input of Fe(III) into the culture media induced the highest iron uptake rate (~3.4 to 4.2 × 10 -16 mol Fe cell -1 d -1 ) by C. sociale during the first day of the incubation, resulting from the sup- ply of bioavailable inorganic Fe(III) species at levels above its expected equilibrium value (~0.1 nmol l -1 ) with solid amorphous Fe(III) hydroxide in seawater. The iron uptake rate during the first day of incubation in solid amorphous Fe(III) hydroxide medium aged for 1 d at 10°C was approximately 50% lower than that in the direct Fe(III) input media. We used a modified approach in which further iron uptake by C. sociale from external iron in the direct Fe(III) input media was prevented by adding hydroxamate siderophore desferrioxamine B (DFB) during cultivation. After the addition of DFB, the highest growth rate (~0.5 to 0.6 d -1 ) of C. sociale by intracellularly stored Fe in the direct Fe(III) input media was maintained for a few days since no iron uptake was observed after the DFB addition. The growth rate was independent of the amount of intracellularly stored Fe. However, the maximal cell yields appeared to be relatively dependent on the amount of intracellularly stored Fe, suggesting the presence of a critical concentration of intracellular Fe (minimum cellular Fe for growth) for phyto- plankton growth (~1 × 10 -16 mol Fe cell -1 for C. sociale). In the present study, maximal and minimal Fe quotas were 3.4 to 4.2 × 10 -16 and ~1 × 10 -16 mol Fe cell -1 (the maximal/minimal Fe ratio of 3.4 to 4.2), respectively. The high iron uptake and storage capacity in C. sociale allows this species to accu- mulate excess iron at high concentrations of bioavailable inorganic Fe species and to support up to 1.8 to 2.1 cell divisions without any additional iron uptake. In addition, we attempted to model the effect of luxury uptake on growth, as biodilution of cellular Fe eventually decreases the Fe quota to a critical threshold.
Lie Symmetry and Painlevé Test for the SIRD Model

In this paper, Lie symmetry and Painlevé Techniques are applied to the SIRD (Susceptible, Infected, Recovered and Dead) model. A demonstration of the integrability of the model is provided to present an exact solution. The study revealed that nonlinear system passes Painlevé test and does not possesses complex chaotic behaviour. However, the system fails to pass the Painlevé test while constraints reach values equivalent to the corresponding complex chaotic behaviour. The two-dimensional Lie symmetry algebra and the commutator table of the infinitesimal generators are obtained. Lie symmetry analysis serves to linearize the nonlinear system and find the corresponding invariant solution.
Potential inhibitors to recovery of Acropora palmata populations in St. John, US Virgin Islands

Populations of Acropora palmata in the Caribbean were decimated in the 1970s and 1980s, with little apparent signs of recovery until the late 1990s. Here, we document an increase in A. palmata colonies between 2001 and 2003 at 8 of 11 monitoring sites in waters adjacent to the island of St. John, US Virgin Islands. The shallow waters along the NW coast of the island exhibited the greatest increase in colony abundance, perhaps due to greater larval supply and/or conditions that favor settlement and subsequent survivorship. Of concern, however, is the lack of survival of large colonies (at all sites), which are most frequently affected by stressors (e.g. Coralliophila abbreviata, damselfishes, active disease) and are most likely to be remnants (colonies with discontinuous, living coral-tissue over an existing coral framework). Predation by C. abbreviata and active coral disease may directly contribute to the development of these remnant colonies. In addition, we recorded damage to colonies attributed to damselfishes and raise the possibility that these territorial reef- inhabitants act as vectors in the transmission of coral disease. While the incidence of disease around St. John is generally low, it may persist as a ubiquitous, chronic stress. Finally, because stressors are more prevalent on large colonies and in high-density stands, they have the potential to inhibit the recovery of A. palmata populations to their historic condition.
The water-like film on water

We have used wavelength scanning close to the Brewster angle of water to determine the relative index of refraction between the surface film and the bulk liquid. The result is clearly that contrary to expectation, the surface film has a higher index than the bulk. This runs counter to molecular dynamics calculations which propose a tapering off of density, and by implication of refractive index. The finding may be more in line with recent suggestions that clusters of hydronium ions may dominate the structure close to the surface.
Orthogonal-plane fluorescence optical sectioning : a technique for 3-D imaging of biomedical specimens

A popular technique for morphological and structural research is Serial Histological Sectioning. In this method, thin sliced sections of fixed, embedded and stained tissue are created, which are then imaged under an optical microscope. A large amount of histological detail can thus be observed with sub-micrometer resolution for cross sectional images of macroscopic biomedical objects. Obtaining these slices is however extremely work-intensive, requires physical (onetime and one-directional) slicing and thus destruction of the specimen. The method requires semi-automatic to manual aligning and image registration of the recorded slices in order to get realistic 3-D reconstructions. Often image processing of the sections is needed because of the geometrical distortions from the slicing. To counter the disadvantages of histological sectioning, the development of optical tomographic imaging techniques came about. As these methods create virtual cross sections through a sample using light, it is said that they perform optical sectioning. This approach is non-destructive and perfectly conserves the topographical position of the cross sections in the specimen. As no physical slicing is performed, the sectioning can also be repeated several times over and/or in different orientations. Several advanced microscopy techniques, such as Confocal Microscopy (CM), allow to obtain high resolution views of certain specimen types. However, because of limited penetration depth the method cannot be applied on large and non-transparent objects. CM uses point-by-point scanning in three dimensions, so a long recording time and inherent bleaching of the specimen are inevitable. Another disadvantage is that light originating from above or below the focal plane will be incorporated in the section image, thus again bleaching but also blurring the section information through out-of-focus interference which decreases longitudinal resolution. Other wide-spread and powerful alternatives are: X-ray micro Computed Tomography or μCT, which records shadow transmission images of X-ray absorption (~ bone tissue), and Magnetic Resonance Imaging or MRI, which is sensitive for water content (~ soft tissue). The usually attainable resolution with these techniques is about 10 μm for objects of macroscopic scale, and they require extensive calculations to reconstruct virtual cross sections. Recent development in X-ray tomography make it possible to reach higher resolutions (even going below micrometer level) [1], and to visualize soft tissue using phase information or staining.

An Interpretive Structural Modeling for Sustainable Healthcare Quality Dimensions in Hospital Services

The purpose of this paper is to develop a comprehensive framework in order to identify, rank and classify key quality dimensions for healthcare establishments (HCEs) and to understand the contextual relationship between them for growth and development of Indian HCEs. The methodology adopted in this research was interpretive structural modelling (ISM) and Matrice d’Impacts Croises Multiplication Appliquee a un Classement (MICMAC) analyses to identify and classify the healthcare quality dimensions (HCQDs), typically identified by an extensive literature review and through experts opinion. The integrated model revealed quality dimensions such as ‘state of knowledge management’; services of HCE for disease burden of society’ and ‘patient expectation and perception of hospital services’ as dependent HCQDs. ‘Priority area management for critical care’ and ‘treatment chain management including referral and evacuation chain management’ were found as the linkage quality dimensions. While ‘core quality dimension’; ‘associated supportive quality dimension’ and ‘clinical governance quality’ were found to be independent HCQDs. This research will aid healthcare practitioners and decision makers in selecting right quality dimensions for the sustainable growth of Indian HCEs.
