Cable Movements Under Two-Dimensional Loads

A numerical method is presented for the determination of the deflected shape of a suspended cable subjected to a general two-dimensional system of gradually applied, concentrated loads. Cable sag is treated. The equations of static equilibrium for the various load points and cable segments between load points are solved in terms of geometrical compatibility requirements by systematic, successive approximations. Other effects, such as temperature change, yielding of the supports, slipping of the cable at the supports, and uniformly distributed loads along parts of the span, are included. Two classes of suspended cable problems are considered: Loads attached at specified points along the cable, and the vertical and horizontal movements of the cable under these loads are determined; and the horizontal location of the final positions of the load points is specified, and the deflections of the load points and the location of their points of attachment in the unstressed condition of the cable are directly determined. The use of the method is demonstrated in three examples.
The Conditioned Medium of Calcined Tooth Powder Promotes the Osteogenic and Odontogenic Differentiation of Human Dental Pulp Stem Cells via MAPK Signaling Pathways

The calcined tooth powder (CTP), a type of allogeneic biomimetic mineralized material, has been confirmed that can promote new bone formation when obtained at high temperature. The aim of this study was to investigate effects of the conditioned medium of calcined tooth powder (CTP-CM) on the osteogenic and odontogenic differentiation of human dental pulp stem cells (hDPSCs) and the underlying mechanisms involved. First, ALP activity assay determined that 200 μg/mL was the optimal concentration of CTP-CM for the following experiments. CTP-CM had no significant effect on the proliferation of hDPSCs as indicated by CCK-8 and FCM analysis. Both the gene and protein (DSPP/DSPP, RUNX2/RUNX2, OCN/OCN, OSX/OSX, OPN/OPN, ALP/ALP, and COL-1/COL-1) expression levels increased in the CTP-CM-induced hDPSC group as compared with those in the control group at day 3 or 7, showing the positive regulation of CTP-CM on the osteo/odontogenic differentiation of hDPSCs. Mechanistically, MAPK signaling pathways were activated after the CTP-CM treatment, and the inhibitors targeting MAPK were identified which weakened the effects of CTM-CM on the committed differentiation of hDPSCs. These findings could lead to the creation of stem cell therapies for dental regeneration.

Dual-order mode (DOMO) all-optical space switch for bidirectional operation

Summary form only given. In conclusion, we have realized a novel monolithically integrated all-optical switch with 8 db fiber-fiber gain, that can be operated in counter- and copropagating direction at any wavelength within the semiconductor optical amplifier (SOA) bandwidth. Furthermore, using a new single order mode (SOMO) configuration, the control signal is intrinsically radiated out, avoiding the use of wavelength-filters.
Sustainable salmon aquaculture and tidal flushing in a macrotidal ecosystem: Cobscook Bay, Maine

Cobscook Bay, Maine is located at the mouth of the Bay of Fundy. Cobscook Bay supports an unusually productive and diverse ecosystem including scallops, clams, mussels, sea urchins and macroalgae, all of which are commercially valuable. Salmon aquaculture has been introduced in Cobscook Bay and the adjoining Passamaquoddy Bay, and aquaculture has become an important contributor to the economy on both sides of the border. In 1995, the salmon aquaculture industry of Maine produced about 10 million kg of fish, mostly from Cobscook Bay (DMR, 1996). The increasing density of salmon pens leads to questions about sustainable levels for aquaculture in the bay because of concerns about nutrient loading and the potential for eutrophication associated with point sources of fish wastes and unconsumed fish feed. The central questions relate to the significance of aquaculture-related nutrient sources compared to natural ones, and the capacity of the tides to flush the bay of pollutants and waste products. At present, Cobscook Bay does not appear to be significantly stressed by either land-based or aquaculture nutrient sources, but there are indications of changes of the ecosystem such as the occurrence of green algal mats in the intertidal zone. To address these issues it is necessary to understand the extent to which the tidal circulation is able to flush pollutants from the bays. This paper summarizes results from experiments with a 3D numerical hydrodynamic model which we have used to estimate residual circulation, dispersion and flushing times in Cobscook Bay.
The Effect of Full Body Versus Partial Body Graphic Labelling on Beverage Packaging

Through the collection of quantitative and qualitative data, the shelf presence of full body graphic labels versus partial body graphic labels on plastic beverage bottles was examined and evaluated. Eye tracking was used to collect phenomenological data atop the stimuli, while a shopping checklist was used to collect purchase preference. A post‐experiment survey was also conducted in order to gather qualitative data regarding possible purchase influences. Data revealed that both label sizes drew an equivalent amount of visual attention; however, consumers selected partial body labels more often than full body labels, regardless of the flavour of the beverage or their age group. Paper presents a unique methodology of comparing attention between the two label styles on plastic beverage bottles. Copyright © 2014 John Wiley & Sons, Ltd.

Colour and textural typologies of goat cream butter with sea buckthorn (Hippophae rhamnoides L.) puree: instrumental, sensory, and consumer input for product development

In this research the effect of the addition of sea buckthorn puree (Hippophae rhamnoides L.) to goat cream butter was examined via analysis of its textural, physicochemical and sensory properties. Consumer acceptance was assessed. The addition of sea buckthorn promoted a stickiness and acidic flavour compared to the original goat butter. The number of consumers who liked goat butter increased by 35 %. The optimal amount of sea buckthorn added was determined as 1.5 %. A larger amount had a negative effect on the colour, as well as creating a more acidic flavour and fruit aroma.
CATHARE code development and assessment methodologies

The CATHARE thermal-hydraulic code has been developed jointly by Commissariat a l`Energie Atomique (CEA), Electricite de France (EdF), and Framatorne for safety analysis. Since the beginning of the project (September 1979), development and assessment activities have followed a methodology supported by two series of experimental tests: separate effects tests and integral effects tests. The purpose of this paper is to describe this methodology, the code assessment status, and the evolution to take into account two new components of this program: the modeling of three-dimensional phenomena and the requirements of code uncertainty evaluation.
Reliability Analysis for Complex, Repairable Systems

Abstract : The reliability of a complex system that is repaired (but not replaced) upon failure will often depend on the system chronological age. If only minimal repair is made so that the intensity (instantaneous rate) of system failure is not disturbed, than a nonhomogeneous Poisson process may be used to model this age-dependent reliability. This paper considers the theoretical and practical implications of the nonhomogeneous Poisson process model for reliability, and gives estimation, hypotheses testing, comparison and goodness of fit procedures when the process has a Weilbull intensity function. Applications of the Weilbull model in the field of reliability and in other areas are discussed. (Author)
Dimensions of microstrip coupled lines and interdigital structures

A method is presented for finding dimensions of coupled lines and interdigital structures on microstrip given the electrical properties. Both a graphical approach and computer approach using polynomial approximations are given. These results are within 1 percent of Bryant and Weiss' dimensions for coupled lines for most practical stripwidths and spacings. Experimental data for a 10-percent bandwidth microstrip interdigital filter are given.
Usage Of An Integrated CAD/CAE/CAM System In Foundries

In today’s competitive age foundries are required to be more active, efficient. They need to respond fast. While CAD/CAE/CAM software can greatly enhance productivity, quality assurance and casting yield, their penetration in small/medium foundries and engineering companies has been poor. This paper reviews how CAD/CAE/CAM assists in designing, modelling, simulating, analyzing and improving cast products over electronic networks – providing a glimpse of the way castings will be designed in future. Key developments in computer-aided product design, casting design, simulation, rapid tooling, intelligent advisory systems and internetbased collaboration are reviewed, supported by relevant vendor information. According to the concept of concurrent engineering (CE), a CAD/CAE/CAM integrated system can shorten the cycle of casting design and manufacture, and result in the production of high quality castings in a shorter time. The lead-time of castings is shortened greatly. The use of CAD/CAE/CAM software greatly improves the speed and accuracy of decisionmaking in individual tasks involved in casting development for a new application.
A Numerical Research of Heat Transfer in Rectangular Fins with Different Perforations

Heat Transfer enhancement needs buoyancy force. This is to be achieved by making perforations on fin surfaces. The present paper is a study on the enhancement of heat transfer in terms of density, velocity and temperature with three different perforation geometry (parallel square, inclined square and circular). CFD was used to carry out the study of density variation, velocity and temperature drop among different perforated fins. This type of perforated fin has an improvement in heat transfer rate over its dimensionally equivalent solid fin.
Total-energy models for phase-stability studies in multicomponent oxides

The computation of thermodynamical properties of oxides from first principles involves the use of both statisticaland quantum-mechanical models. We show that the solution of the former models can be considerably simplified with a low-temperature expansion of the free energy. This overcomes the numerical problems of standard statistical-mechanical techniques at low temperatures or for highly-stoichiometric compounds. We find that with only a few terms in the expansion, an accurate description is obtained up to temperatures where Monte Carlo simulations or cluster variation calculations are practical. The formation energies of a large number of real or hypothetical compounds are an essential input to compute free energies. These values are usually obtained from sophisticated and time-consuming quantum-mechanical calculations. We show that the same accuracy can be obtained from simpler approaches when all the relevant contributions in the Hamiltonian are properly included. We identify four effects that are necessary to accurately reproduce formation energies in oxides: charge transfer, nonspherical electronic relaxations, ionic breathing, and directional bonding. We successfully integrated these effects into a tight-binding formulation. The Hamiltonian of the model includes explicit parametrizations of these terms. The parameters are fit to pseudopotential bands and equations of state. From this information, formation energies can be obtained with an accuracy comparable to the pseudopotential predictions, but at a fraction of the computational cost. On average, the tight-binding formation energies in the CaO-MgO and CaO-ZrO 2 systems only differ by 10% from the pseudopotential results. As an example of the applicability of the new tight-binding scheme to complex oxides, we use it to study the dependence of the ionic charge on the atomic environment. We show that the variations in valence state can be important and produce significant errors in the formation energies when they are not properly accounted for.

Computation of SAR in Cell Culture Flasks Exposed to 900 MHz GSM Type Signals in a Modified TEM Cell

Abstract : In order to provide rigorous dosimetry for in vitro studies, Telstra Research Laboratories has developed a modified transverse electromagnetic cell exposure system. The system acts as a chamber for experiments in which a human cell culture exists as a very thin monolayer adhered to the bottom of a plastic culture flask under a layer of several millimetres of RPMI nutrient medium while incubated in a controlled atmosphere. A key to the rigour of any experiment seeking to investigate possible effects of electromagnetic energy on living systems is to ensure that the exposures used are accurately known, and to achieve this, numerical methods for the challenging task of characterizing the SAR profile in the medium have been developed. This paper describes salient aspects of the development and analysis of the system.
Improving the efficiency of high power piezoelectric transducers for industrial applications

Most high-power ultrasound applications are driven by two-level inverters. However, the broad spectral content of the two-level pulse results in undesired harmonics that can decrease the performance of the system significantly. On the other hand, it is crucial to excite the piezoelectric devices at their main resonant frequency in order to have maximum energy conversion. Therefore a high-quality, low-distorted power signal is needed to excite the high-power piezoelectric transducer at its resonant frequency. This study proposes an efficient approach to develop the performance of high-power ultrasonic applications using multilevel inverters along with a frequency estimation algorithm. In this method, the resonant frequencies are estimated based on relative minimums of the piezoelectric impedance frequency response. The algorithm follows the resonant frequency variation and adapts the multilevel inverter reference frequency to drive an ultrasound transducer at high power. Extensive simulation and experimental results indicate the effectiveness of the proposed approach.
Kalman Filtering and Neural Networks

From the Publisher: Kalman filtering is a well-established topic in the field of control and signal processing and represents by far the most refined method for the design of neural networks. This book takes a nontraditional nonlinear approach and reflects the fact that most practical applications are nonlinear. The book deals with important applications in such fields as control, financial forecasting, and idle speed control.
ON THE DEVELOPMENT LIFE CYCLE OF DISTRIBUTED FUNCTIONAL APPLICATIONS: a case study

I a world where technology plays a major, increasing role day after day, efforts devoted to develop better software are never too much. Both industry and academia are well aware of this, and keep on working to face the new problems and challenges that arise, more efficiently and effectively each time. Companies show their interest in cutting-edge methods, techniques, and tools, especially when they are backed up with empirical results that show practical benefits. On the other hand, academia is more than ever aware of real-world problems, and it is succeeding in connecting its research efforts to actual case studies. This thesis follows the mentioned trend, as it presents a study on software applications development based on a real case. As its main novelty and contribution, the integral process of software development is addressed from the functional paradigm point of view. In contrast with the traditional imperative paradigm, the functional paradigm represents not only a different way of developing applications, but also a distinct manner of thinking about software itself. This work goes through the characteristics and properties that functional technology gives to both software and its development process, from the early analysis and design development phases, up to the final and no less critical verification and validation stages. In particular, the strengths and opportunities that emerge in the broad field of testing, thanks to the use of the functional paradigm, are explored in depth. From the analysis of this process being put into practise in a real software development experience, we draw conclusions about the convenience of applying a functional approach to complex domains. At the same time, we extract a reusable engineering methodology to do so.
IMPORTANCE OF EMPLOYABILITY SKILLS FOR ENGINEERING STUDENTS

Success in work place does depend on specific skill other than technical knowhow. What ever be the chosen field of profession everyone needs to hone their soft skills to ensure consistency. Soft skills are intangible skills like Interpersonal skills, communication, team work, leadership qualities, creativity, etc to cite a few examples. These skills that make an individual to adapt to various situations and overcome challenges and succeed. The Engineering education provides the required manpower for the technological development, but how far they are successful and what is the gap that should be bridged. A study on the current scenario and the possible solution to tackle the situation is discussed in this paper.
On Modeling, Fault Detection and Fault Isolation of Valve and Pipe System

Valve and pipe systems are used in many areas. Often there is redundancy in the system. If one valve breaks it may be possible to lead the gas (or fluid) another way. To do this automatically we have to be able to detect and isolate faults. In this report, we show a way to use discrete event dynamical system models for analyzing where to put sensors in a valve and pipe system.
