The design of 5 GHz voltage controlled ring oscillator using source capacitively coupled current amplifier

A 5 GHz voltage controlled ring-oscillator (VCO) has been designed using 0.18 /spl mu/m CMOS technology. Source Capacitively Coupled Current Amplifier (SC3A) is adopted to realize this VCO. Because of the band-pass characteristic of the SC3A, this VCO exhibits the low noise performance with a large tuning range. It can operate from 4.3 GHz up to 6.1 GHz with a phase noise of about -85 dBc/Hz at 1 MHz frequency offset. For the 2 V supply voltage, the power consumption is about 80 mW.
A NPR Technique of Many Pieces Rendering

To provide with an effective method for non-photorealistic rendering for computer generated images with artistic appearances from 2D images motivates our work in this paper. The methods proposed in this paper are inspired by the many pieces synthesis mosaic effects. In this paper, we mainly propose the method for generating the artistic appearances based on the pieces synthesis and color tranfer technique. The block pieces can be chosen from arbitrary quantity images in the database. First, to accelerate synthesis speed, the mosaic effect can be generated based on the luminance channel. Further, we establish our method for obtaining RGB appearances taking the color transfer as the underlying basis. Therefore, the color of input image can be rendered to the final mosaic artistic effects. Experimental results show that our methods are effective and efficient.

LEADERSHIP 2.0 AND WEB2.0 AT ERM: A JOURNEY FROM KNOWLEDGE MANAGEMENT TO "KNOWLEDGING"

AbstractThis paper introduces Dervin's Sense-Making Methodology (SMM) as an approach to KM system design using Web2.0. SMM is a philosophically derived approach which allows knowledge management (KM) researchers and practitioners to more fully understand and listen to user's needs so as to inform the design of dialogic KM practices and systems to promote knowledge sharing. Increasingly, KM systems are incorporating Web2.0 features which allow user-generated content and have a stronger emphasis on collaboration and interaction amongst users. This paper presents a "Safety Moment" project to illustrate how SMM has been applied to inform the design of a Web2.0 enabled 'knowledging' application in Environmental Resources Management (ERM), the world's largest all-environmental consulting firm. The project discussed has been implemented since January 2008 as part of ERM's commitment to improve Health & Safety Performance to ensure all ERM employees, contractors and clients are safe at work. Use of the SMM informed Web2.0 application has correlated with increased staff satisfaction, increased company reputation and reduced risks. Much is said about the need for a Leadership 2.0 to implement Web2.0. The authors argue that this project exemplar illustrates how to make Web2.0 work, we need to define Leadership 2.0 as a set of alternative management values and practices driven by a set of coherent assumptions about the nature of human communication.
Modeling Traveler's Day-to-Day Rerouting Behavior considering Multiday Experiences

This paper proposes a multiday nonlinear pairwise swapping dynamic (MNPSD) model to describe travelers' day-to-day selfish rerouting behaviors. By introducing a perceived route cost measure, formulated as the descending weighted average of the actual route costs experienced in the past several days, MNPSD can capture various experiential perception levels. It is proved that both stationary path flow pattern and stationary link flow pattern of MNPSD are equivalent to Wardrop user equilibrium. Given that the perceived weight decreases exponentially, numerical sensitivity analyses are executed to explore the effects of experiential perceptions on rerouting behaviors. Numerical results suggest that (1) the ultimate states of route swaps depend much more on the reaction sensitivity than on the capacity interference, (2) too much dependence on the historical experience can increase the risk of instability rather than stability, and (3) for high reaction sensitivity network, the instability can be remedied by incorporating proper perception experience.
Assess the Prevalence for Needs of Breast Cancer Survivors' in the Oncology Ward at a Selected Tertiary Care Hospital

The unmet needs of breast cancer survivors are not being addressed as the number of survivors continues to climb. Aim and Objective: To determine the prevalence of post-treatment unmet needs and association between unmet needs of breast cancer survivors with selected demographic variables. A descriptive research study was conducted in a tertiary care hospital's oncology outpatient clinic and wards. Materials and Methods: Data was gathered in two sections: I – baseline data, and section II – Modified needs assessment questionnaire. 35 needs were categorized as physical, emotional, family, spiritual, practical routine, and sexual relationship needs, with ‘Yes’ scored as ‘1’ and ‘No’ scored as ‘0’. Data was collected for one month. Data tabulation and analysis was done. Results: The majority of BCS had a monthly income of Rs.3000- 10000/- (50.8%) and menopause had occurred in 54 (45%) of the women under the age of 45. Majority 65 (78%) did not have health insurance, whereas 42 (35%) had it. Majority 108 (90.33%) breast cancer survivors had high level of needs, whereas 12 (10%) had moderate level of needs. High physical needs reported by 87 (72.50 %) and 32 (26.67%) moderate physical needs. All 100% BCS reported high emotional need. Whereas 2(1.67%) less need, 14(11.67%) moderate, 56 (46.67%) high needs and 48 (40%) very high reported family and spiritual need and 39 (32.5 %) BCS reported moderate level of practical needs. Participants 14(11.67%) less needs, 39 (32.50%) moderate, 22(18.33%) high and very high 8(6.67%) reported practical needs. 100% of breast cancer survivors (BCS) reported physical includes Hot flashes, a change in appetite or eating pattern. High emotional needs followed by physical needs. Family and spiritual requirements of BCS were found to be strongly related to age, P 0.036. Age, education, occupation, income, stage of cancer, and health insurance are not associated with the overall and physical needs of breast cancer survivors (p > 0.05). Conclusion: Breast cancer survivors' needs are more prevalent and have an impact on quality of life, prognosis, and recovery of clients. Real, appropriate assessment of breast cancer survivors needs is an important steps in development of need base intervention to improve quality of life. As a result, health care providers should address the needs of BCS patients as soon as possible in order to make better use of scarce health resources.

High step-up resonant push-pull converter with high efficiency

A high-efficient current-fed push-pull converter is proposed for high output voltage applications supplied by low-voltage and high-current sources such as fuel cells and solar cells. The proposed converter conserves inherent advantages of a conventional current-fed push-pull converter such as low input current stress and high-voltage conversion ratio. The converter employs a voltage-doubler rectifier in order to remove the reverse-recovery problem of the output rectifying diodes and to provide much higher voltage conversion ratio. Additionally, by allowing the duty ratio < 0.5, the converter operates in wider input voltage range, and the ripple current of a boost inductor is reduced, compared with the conventional one. Moreover, as the duty ratio approaches 0.5, the ripple of the inductor current moves in close to zero. The operation of the proposed converter is analysed and experimental results obtained from a prototype verify the analysis. The prototype was implemented for an application requiring a 1.5 kW output power, input voltage range varying from 35 to 60 V, and 350 V output voltage. Experiment results show that minimum efficiency at full load is about 95.5%.

Effect of inset feeding on antenna properties in a superconducting microstrip antenna

Effects of ‘inset feeding’ on microstrip antenna properties have been investigated by analysing the designed and experimental results. Dimensions of a single-patch antenna with this feed architecture have been optimized with an operating frequency of 11.74 GHz with the aim of using it to fabricate a superconducting microstrip array antenna for a direct broadcast satellite (DBS) communication system. In our observation, the antenna gain, resonant frequency and input impedance of the antenna are found to change with change of the feed architecture. A single-patch YBa2Cu3O7−δ (YBCO) superconducting antenna and a gold antenna with this optimized structure have been fabricated for the comparison of properties between these two types of antennas. The comparison of the gain between the YBCO superconducting and gold antennas measured at 77 K shows that the YBCO antenna has 1.8 dB higher gain than the gold antenna with an identical configuration.
AC drive with particular reference to traction drives

New developments in the design of high speed electric trains are discussed, with reference to the AC drive system. The three level converter-inverter system applying advanced IGBTs, which is implemented in the latest Shinkansen train sets operating in eastern Japan between Tokyo and Nagano, is described. Advanced control techniques lead to a unity power factor seen by the AC supply as well as minimising the line harmonics, power loss, motor torque ripple, and audible noise. Therefore by using advanced AC drive systems the high speed train offers high level performance, efficiency, and passenger comfort.

Reliability Test Plan Based on Logistic-Exponential Distribution and Its Application

In this article, a reliability test plan is developed for Logistic-exponential distribution (LoED) under time truncated life test scheme. The distribution has been chosen because it can used to model lifetime of several reliability phenomenon and it performs better than many well known existing distributions. With the discussions of statistical properties of the aforesaid model, the reliability test plan has been established under the assumption of median quality characteristics when minimum confidence level P* is given. To quench the objective of the paper i.e; to serve as a guiding aid to the emerging practitioners, minimum sample sizes have been obtained by using binomial approximation and Poisson approximation for the proposed plan. Further, operating characteristic (OC) values for the various choices of quality level are placed. Also, minimum ratio of true median life to specified life has been presented for specified producer’s risk. Important findings of the proposed reliability test plan are given for considered value of k=0.75,1,2. To demonstrate the appropriateness of suggested reliability test plan is achieved using four real life situation.
A STUDY ON THE COLOR AND STYLE COLLOCATION OF MOBILE PHONES USING NEURAL NETWORK METHOD

ABSTRACT There are a variety of mobile phones in the market. In order to attract consumers, the manufacturers of mobile phones vary the designs in style and in color. However, what style of mobile phone is just suitable for the color? If the color change of mobile phone could influence the style of mobile phone. In order to explore the relationships among color, style and Kansei vocabularies, thirty popular mobile phones were used and investigated. The liner model of Quantity and the non-liner model of Neural Network are used to analyze the experimental results. Finally, the non-liner model of Neural Network is used to infer the styles and colors of new mobile phones. This study showed that: 1) From results of the liner model of Quantitative Theory Type I, the color factor is more important than the style factor on the Kansei vocabularies in this case. 2) The “Value” factor primarily affects the “single-complex” and “leisure- formal” Kansei vocabularies, but the “Hue” factor mainly influence the “smart-rustic” Kansei vocabularies. 3) The “Chroma” is the least significant factor on any pair of Kansei vocabularies among Hue, Chroma and Value. 4) According to the results of testing new samples, the Neural Network has the highest predicted accuracy on the “single-complex” Kansei vocabularies; followed by the “smart-rustic” Kansei vocabularies. However, it is chaotic on the “leisure-normal” Kansei vocabularies. The results of this study could be derived a Decision Support System for evaluating the relationships among the style, color and Kansei vocabularies. Finally, the methods of this study can be applied at studying the relative products.
Quality Assessment of Hardwood Seedlings

“Seedling quality” is an expression used to describe the extent to which a seedling may be expected to successfully survive and grow after outplanting (Duryea 1985; Mattsson 1997). For many decades, measurements of morphological and physiological characteristics have been used to predict field performance of seedlings and their ability to tolerate mechanical and environmental stresses. However, compared to conifers, literature is relatively deficient in hardwood seedling quality research. Research cooperatives such as the Purdue University/USDA-Forest Service Hardwood Tree Improvement and Regeneration Center are focusing on seedling quality, production, and regeneration problems specific to hardwood species.
Disrupting ATXN1 Nuclear Localization in a Knock-in SCA1 Mouse Model Improves a Spectrum of SCA1-Like Phenotypes and their Brain Region Associated Transcriptomic Profiles

Spinocerebellar ataxia type 1 (SCA1) is a dominant trinucleotide repeat neurodegenerative disease characterized by motor dysfunction, cognitive impairment, and premature death. Degeneration of cerebellar Purkinje cells is a frequent and prominent pathological feature of SCA1. We previously showed that transport of ATXN1 to Purkinje cell nuclei is required for pathology, where mutant ATXN1 alters transcription. To examine the role of ATXN1 nuclear localization broadly in SCA1-like disease pathogenesis, CRISPR-Cas9 was used to develop a mouse with the amino acid alteration (K772T) in the nuclear localization sequence of the expanded ATXN1 protein. Characterization of these mice indicates proper nuclear localization of mutant ATXN1 contributes to many disease-like phenotypes including motor dysfunction, cognitive deficits, and premature lethality. RNA sequencing analysis of genes whose expression was corrected to WT levels in Atxn1175QK772T/2Q mice indicates that transcriptomic aspects of SCA1 pathogenesis differ between the cerebellum, brainstem, cerebral cortex, hippocampus, and striatum.
WAVELET-HYBRID FEEDBACK-LEAST MEAN SQUARE ALGORITHM FOR ROBUST CONTROL OF STRUCTURES

In a companion article, the writers presented a hybrid feedback-least mean square (LMS) algorithm for control of structures through integration of a feedback control algorithm such as the linear quadratic regulator and linear quadratic Gaussian algorithms and the filtered-x LMS algorithm. Low-pass filtering of dynamic environmental disturbance signals due to winds and earthquakes is required when the hybrid feedback-LMS algorithm is used for control of civil structures, because the frequency bandwidths of such environmental signals are much wider than those of common structural systems. In this paper, it is shown that the wavelet transform can be used as an effective filtering scheme for control problems. A wavelet-hybrid feedback-LMS algorithm is presented for robust control of civil structures. The effectiveness of the proposed control model is demonstrated by application to an active tuned mass damper system and an active mass driver benchmark problem. Simulation results demonstrate that the proposed model is effective for control of both steady and transient vibrations without any significant additional computational burden, and can be used readily to enhance the performance of existing feedback control algorithms.
Urinary liver‐type fatty acid‐binding protein as a prognostic marker in patients with acute heart failure

Urinary liver‐type fatty acid‐binding protein (L‐FABP) is expressed in proximal tubular epithelial cells and excreted into the urine during tubular injury. We hypothesized that high urinary L‐FABP is associated with poor prognosis in patients with acute heart failure (AHF).
Building water resilience into strategy: The Cape Town drought

The Cape Town drought captured the world's attention at the beginning of 2018 with the announcement of Day Zero: the day that Cape Town's taps would run dry. In the eye of the storm a host of factors contributed to the panic, and rapidly falling dam levels. Politics was exceptionally conflictual, interaction between spheres of government responsible for various aspects of water supply far from perfect, with public perception and media frenzy driving a focus on matters which played a very small part in the effort not to run out of water. During this time, Cape Town was building a water strategy, specifically aimed at making Cape Town more resilient against future droughts by addressing all possible factors contributing to the drought crisis. With dams close to overflowing in 2020, the next challenge is to ensure that the strategy is implemented according to plan.
The system’s view for clarification of quality vocabulary

As a result of the increasing complexity of technology, processes and products, as well as worldwide pressures for competitive quality, quality terminology keeps expanding and changing. Although an internationally accepted quality vocabulary exists, namely ISO 8402: 1994, we still encounter serious confusion and misunderstanding when communicating on quality related matters. This is evident not only at the international level, but in daily operations, as well. In order to improve communication in quality related matters, we propose the “system’s view” be used. In this article, the “system’s view” is explained, followed by a focus on the application of the underlying concept of a system to quality. Four examples are used: the ISO 9001 Quality System, the ISO 9004 Quality Management Guidelines, the ISO 10011 Quality Audit System, and the ISO 14001 Environmental Management System. The ISO 8402 Vocabulary is streamlined using the “system’s view”. Finally, the benefits of this view for creating quality vocabulary are discussed.
