Configuring performance measurement scorecards for Crm

Scorecards are a concept for structuring systems of key figures and the anchoring of such systems in the reporting system of the enterprise. Recently such performance measurement systems are increasingly being discussed in academia and in practice as a basis for the development and implementation of holistic Crm concepts. The present paper sketches the concept of the customer management scorecard for Crm and its primary configuration possibilities.
AlGaN/GaN HEMTs on Si(111) with 6.6 W/mm output power density

Al/sub 0.27/Ga/sub 0.73/N/GaN HEMTs have been realised on resistive Si(111) substrates. The epitaxial structure was grown by MBE yielding a channel mobility of 1440 cm/sup 2//Vs (room temperature) and a sheet carrier density of 9.6e12 cm/sup -2/. Large signal evaluation of transistors with gate length of 0.25 /spl mu/m and gate width of 2/spl times/125 /spl mu/m yields up to 1.65 W CW output power at 2 GHz corresponding to a power density of 6.6 W/mm. These results are thought to represent the highest output power density so far achieved for GaN-based HEMTs on silicon substrates.
Protection of VSC-multi-terminal HVDC against DC faults

Voltage-source converters (VSCs), by themselves, are defenseless against DC faults. Their anti-parallel diodes conduct as rectifier bridges to feed the fault. Their IGBTs (insulated gate bipolar transistors) are helplessly by-passed, unable to extinguish the fault current. This paper shows how a VSC-multi-terminal high voltage direct current (MTDC) transmission system can survive DC faults by a using protection scheme based on: (1) fast, reliable fault detection; (2) blocking of IGBT-circuit breakers (IGBT-CBs) and blocking of the IGBTs of VSCs; (3) locating of the faulted DC line; (4) isolation of the faulted DC line by economical fast DC switches; and (5) de-blocking of IGBT-CBs and IGBTs of VSCs to resume normal service.
A study of the practicality and profit enhancement potential of demand driven dispatch in airline hub operations

This thesis explores the use of demand driven dispatch in the hub and spoke environment prevalent in the route networks of major airlines in the United States. Demand driven dispatch is an operational mode where aircraft assignments can be changed in response to variation in demand. A computer program simulated the functions of a revenue management system and an optimal aircraft assignment routine over the course of the passenger booking process. An isolated hub with service exclusively between the hub and 15 spoke cities was assumed. Two series of quantitative studies were done, one looking at the possible profit improvements at various demand levels with demand driven dispatch and the other examining the sensitivity of demand driven dispatch results to when the first and last optimal reassignment of hub aircraft was made in the booking process. In the first series, comparisons were made between results obtained from static aircraft assignments and fully dynamic demand driven dispatch assignments. Several scenarios were simulated. These involved various combinations of demand distribution, demand balance, and booking process assumptions. Booking process sensitivity studies were performed on a small subset of the scenario combinations. A discussion of practical issues which could affect implementation is also included. Results show that demand driven dispatch performance is fairly uniform regardless of the scenario with the best projected yearly profit increases for a major hub and spoke operator of $35-$40 million over the current fixed assignment practice. This occurred at load factors similar to airline historical levels of 65%. The profit increases at normal demand levels were achieved mostly through better aircraft utilization patterns (lower costs) and not revenue enhancement. At higher average load factors demand driven dispatch improvement was less significant but was always positive. Studies on when demand driven dispatch was applied during the booking process showed that major benefits could be gained by evaluating assignments even once as long as this assignment period preceded any significant level of high yield passenger booking requests.

Effect of acupuncture and its influence on cerebral activity in patients with persist asthma: study protocol for a randomized controlled clinical trial

Previous studies suggested that acupuncture was a promising adjunct treatment for asthma. However, the underlying mechanism of acupuncture for asthma remains unclear. The present trail aimed to explore whether and how specific meridian acupuncture works in quality of life and symptomatic improvement by modulating brain function in asthma patients. A randomized controlled functional brain imaging trial is currently being conducted in Sichuan, China. In total 48 patients with mild to moderate, persist asthma will be recruited randomly allocated to two acupuncture groups: acupuncturing at Lung Meridian and acupuncturing at Heart Meridian . The treatment period will last for 4 weeks. The Asthma quality of life questionnaire (AQLQ) is the primary outcome. Asthma control test (ACT), the rate of Peak expiratory flow (PEFR), Forced expiratory volume in 1 second (FEV1), Montreal cognitive assessment (MoCA), Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) will also assess the clinical efficacy of different interventions. Functional magnetic resonance imaging (fMRI) scans will be performed to detect cerebral activity changes in each group. The clinical data and fMRI data will be analyzed, respectively. Pearson correlation analysis will be used to assess the association between the changes of cerebral activity features and the improvement of clinical outcomes in each group. relationship” The results of this would be useful specific The investigation of its central mechanism would further expand our ACC: Anterior Cingulate ACT: Asthma Control Test; Low-frequency Fluctuation; AQLQ: Asthma Quality of Life Questionnaire; BOLD-fMRI: Blood Oxygenation Level-dependent fMRI; CDUTCM: Chengdu University of Traditional Chinese Medicine; CRF: Case Report Form; DTI: Diffusion Tensor Imaging;3D-T1WI:Three-dimensional T1-weighted EEG: Electroencephalography; FD: Functional Dyspepsia; FEV1:Forced Expiratory Volume in 1 GCBT: Behavioral Therapy; GINA: for ICA: Component Analyses; ICS: Corticosteroids; Ig E:Immunoglobulin IRB: Institutional Review LABA: Long-acting β2 Agonist; Magnetoencephalography; MoCA: Montreal Cognitive the Rate of Peak Expiratory Flow; PET: Positron Tomography; RCTs: Randomized Controlled Trials; SAEs: Serious SAS: Self-rating Anxiety Scale; SDS: Self-rating Depression Scale; Visual Analogue Flowchart the trial. present a randomized controlled neuroimaging trial.

Nonlinear vibration analysis of the high-efficiency compressive-mode piezoelectric energy harvester

Power source is critical to achieve independent and autonomous operations of electronic mobile devices. The vibration-based energy harvesting is extensively studied recently, and recognized as a promising technology to realize inexhaustible power supply for small-scale electronics. Among various approaches, the piezoelectric energy harvesting has gained the most attention due to its high conversion efficiency and simple configurations. However, most of piezoelectric energy harvesters (PEHs) to date are based on bending-beam structures and can only generate limited power with a narrow working bandwidth. The insufficient electric output has greatly impeded their practical applications. In this paper, we present an innovative lead zirconate titanate (PZT) energy harvester, named high-efficiency compressive-mode piezoelectric energy harvester (HC-PEH), to enhance the performance of energy harvesters. A theoretical model was developed analytically, and solved numerically to study the nonlinear characteristics of the HC-PEH. The results estimated by the developed model agree well with the experimental data from the fabricated prototype. The HC-PEH shows strong nonlinear responses, favorable working bandwidth and superior power output. Under a weak excitation of 0.3 g (g = 9.8 m/s2), a maximum power output 30 mW is generated at 22 Hz, which is about ten times better than current energy harvesters. The HC-PEH demonstrates the capability of generating enough power for most of wireless sensors.
The Demand for Tourism in the Province of Erbil, Especially during the Winter Season of 2015-2016

The picturesque nature and water resources in the Kurdistan Region stimulate many tourists in the neighboring areas to come to the arena and spend a pleasant time. As the economy of the Kurdistan region recovers, its tourism industry is also booming, and tourism demand is rising. At the macro level of the Kurdistan Region, the annual increase in tourist demand (tourist arrivals) increased during the period years 2007-2013, which was about 33% in 2013, while the rate declined significantly in 2014 to 48% due to the ISIS war, and the financial crises. However, at the level of Erbil governorate, a random sample of 201 tourists was taken in the winter of the year 2015-2016, where most of them (22.4%) spent 100,000 dinars on each trip. About 30% of the people surveyed travel once a year, another 30% travel twice a year, and 16% travel three times a year. The explanatory variables of the tourism demand model in Erbil governorate consist of: The effects of high prices, transportation means, tourism expenses, reservation system, income level, and educational level have significant effects on the dependent variable (number of tourism times per year), because the calculated F statistic is greater than F tabular, with Ṝ2= 68.6%. While the most significant variables affecting the demand model individually (ceteris paribus) are clarified by the t-test at the level of 5% alpha consisting of; price effects, transportation means, tourism expenses, and reservation system.
31.3: A 10‐bit CMOS Digital‐to‐Analog Converter with Logarithmic Time Interpolation

A 10‐bit logarithmic time interpolation digital‐to‐analog converter (DAC) which consists of a 7‐bit resistor string, a 7‐bit two‐step decoder, a 2‐bit logarithmic time interpolator, and a buffer amplifier is proposed for data‐driver integrated circuits of active‐matrix liquid crystal display systems. It occupies 57% of the area of the conventional 10‐bit resistor‐string DAC. The DNL and INL of the implemented 10‐bit DAC were +0.29/‐0.30 and +0.47/‐0.36 LSB, respectively, where 1 LSB is equal to about 4.5 mV.
Output-only structural health monitoring in changing environmental conditions by means of nonlinear system identification

Structural health monitoring relies on the repeated observation of damage-sensitive features such as strains or natural frequencies. A major problem is that regular changes in temperature, relative humidity, operational loading, and so on also influence those features. This influence is in general nonlinear and it affects different features in a different way. In this article, an improved technique based on kernel principal component analysis is developed for eliminating environmental and operational influences. It enables the estimation of a general nonlinear system model in a computationally very efficient way. The technique is output-only, which implies that only the damage-sensitive features need to be measured, not the environmental parameters. The nonlinear output-only model is identified by fitting it to the damage-sensitive features during a phase in which the structure is undamaged. Afterwards, the structure is monitored by comparing the model predictions with the observed features. The technique is validated with natural frequency data from a three-span prestressed concrete bridge, which was progressively damaged at the end of a one-year monitoring period. It is demonstrated that capturing the regular variations of the features requires a nonlinear model. Monitoring the misfit between the predictions made with this model and the observed data allows a very clear discrimination between validation data in undamaged and damaged conditions.
The Precise Measurement of Current Ratios

The development of the current comparator, a three-winding current ratio transformer, is reviewed and its characteristics as an alternating current ratio standard are analyzed. Particular attention is given to the use of magnetic shielding and its effect on the accuracy and usefulness of the device. Some error characteristics of three types of audio-frequency current comparators are given and possible applications discussed. These include the calibration of current transformers and impedance comparisons. The adaptation of this device to dc operation is made possible by modulation techniques. A 20 000-ampere self-balancing direct current comparator, designed specifically for the calibration in situ of transductors or direct current transformers, is described. The application of this comparator to the calibration of shunts at high currents also is discussed and some results presented.
What is infrastructure

: After having pointed out the diverse uses of the term "infrastructure" in the literature on the market-economy, the different categories of infrastructure will be described. The argument in this context is that the classification of infrastructure suggested by Jochimsen has proved useful: institutional, personal, and material infrastructure. On this basis a concept for the definition of infrastructure will be developed. The hitherto taken approach to understanding infrastructure, especially material infrastructure, mainly referring to the attributes of infrastructure, will be rejected. Rather it will be attempted to characterize infrastructure by its essential functions. We then may discuss the development-theoretic implications of infrastructure. Finally, infrastructure policy will be introduced in relation to institutional, material and personal infrastructure.
A stochastic hybrid model of DNA replication incorporating 3D protein mobility dynamics

DNA replication, the basis of genetic information maintenance, is a remarkably robust yet highly stochastic process. We present a computational model that incorporates experimental genome structures and protein mobility dynamics to mechanistically describe the stochastic foundations of DNA replication. Analysis of about 300,000 in silico profiles for fission yeast indicates that the number of firing factors is rate-limiting and dominates completion time. Incorporating probabilistic activation and binding, a full-genome duplication was achieved with at least 300 firing factors, with the only assumption that factors get recycled upon replication fork collision. Spatial patterns of replication timing were reproduced only when firing factors were explicitly activated proximally to the spindle pole body. Independent in vivo experiments corroborate that the spindle pole body acts as a replication activator, driving origin firing. Our model provides a framework to realistically simulate full-genome DNA replication and investigate the effects of nuclear architecture.
Guidance for improving foundation layers to increase pavement performance on local roads.

This document is the second of two deliverables for the project Optimizing Pavement Base, Subbase, and Subgrade Layers for Cost and Performance on Local Roads (TR-640). The first deliverable is the 454-page Final Field Data Report. The field data report describes test results and comparative analysis from 16 different portland cement concrete (PCC) pavement sites on local city and county roads in Iowa. At each site the surface conditions of the pavement (i.e., crack survey) and foundation layer strength, stiffness, and hydraulic conductivity properties were documented. The field test results were used to calculate in situ parameters used in pavement design methodologies for American Association of State Highway and Transportation Officials (AASHTO) (1993) and Iowa’s Statewide Urban Design and Specifications (SUDAS). Overall, the results of the study demonstrate how in situ and lab testing can be used to assess the support conditions and design values for pavement foundation layers and how the measurements compare to the assumed design values. This guide summarizes the study results and outlines general guidelines for applying them to optimize pavement bases, subbases, and subgrade layers of local roads with PCC pavements and thus their performance.
The Generation, Impact, and Management of E-Waste: State of the Art

Even as the world has been unsuccessfully trying to dispose off the rising quantities of its municipal solid waste (MSW) and hazardous waste (HW) in a clean manner, it has been confronted with an even more complex problem—of e-waste. Only a few countries in the developed world are able to scientifically recycle or dispose the e-waste they generate. In other developed countries only a fraction of the e-waste is properly recycled, the rest is either incinerated or sent to landfills—which are solutions that cause serious secondary problems. Worse still, a sizeable portion of the e-waste generated in the developed world is exported to developing countries where it is recycled or dumped without any concern for the gross pollution that is being caused. It can be said that if the situation vis-à-vis e-waste is posing a challenge in most developed counties, it is alarmingly bad in the developing world. In an attempt to contain the e-waste problem most of the developed world and several countries in the developing world have enacted legislation to curb illegal trafficking and unlicensed recycling of e-waste. These legislations invoke the extended producer responsibility concept based on life-cycle considerations in the hope that it will provide prevention as well as cure. Innumerable non-governmental organizations and citizen's groups have also been trying to help out. So far, all these measures together have achieved only a modicum of success—that, too, only in a few regions of the developed world—but if viewed on the global scale ever bigger streams of e-waste are threatening to join the rising tides of MSW and HW in engulfing the world. The present paper assesses the state-of-the-art, bringing out how and why the e-waste problem has been defying all attempts to contain it. The paper also brings out that—much the same way as has happened with MSW and HW—the size and the complexity of the e-waste problem is increasing at much faster rate than the efficacy of our strategies to contain it. This trend is not likely to reverse soon and the only viable means to solve the problem is to drastically reduce generation of waste.
Field trial of virtual-grouped-wavelength-path switching with QPM-LN waveband converter and PLC matrix switch in JGN II test bed

Contention resolution of grouped-wavelength-paths is successfully demonstrated using polarisation-independent multichannel wavelength conversion in a QPM-LN waveguide and 8/spl times/8 planar lightwave circuit matrix-switching. The function is confirmed using wavebands composed of 8 channel/spl times/10 Gbits/s transmitted through field-installed fibres in the JGN II test bed.
Accuracy and Reliability Control of Machining Operations on Machining Centres

During machining operations on machining centres, there are a large number of internal and external factors that act on the technological system. They generate errors that influence the manufacturing cost, productivity, and machining accuracy. The monitoring and control system developed for machining centres presented in this paper consists of 3D touch probes, a device for registering a contact between the cutting tool and workpiece, devices for measuring the geometric accuracy of the machine tool and for calibrating the touch probe in the spindle, parameterised CNC programmes, computer and software for data processing and database management. The developed system guarantees monitoring of the machining accuracy, low cost, high level of productivity, low number of preparatory work and measurements, increased reliability due to reduced scrap rate by reducing the probability of cutting tool breakage, the possibility of automating the measurements and processing the data, and wide applicability.

A review of colour rendering indices and their application to commercial light sources

,! The CIE colour rendering index (Ra) is the most widely used measure for quantifying and comparing the colour rendering performance of light sources. Despite its prominence Ra is not without limitations, including its reliance on reference standards and the inability to compare the Ra of sources with different correlated colour temperatures. Other colour rendering measures have been proposed including several based on colour preference, others based on absolute scales, and some that are graphical rather than numerical. This paper utilizes nine colour rendering indices to assess and compare the performance of common light sources and theoretical illuminants. Following this assessment, recommendations for the use of existing tools are made, as well as suggested strategies for future colour rendering measures.
