This paper surveys recent and historical publications on automotive powertrain control. Control‐oriented models of gasoline and diesel engines and their aftertreatment systems are reviewed, and challenging control problems for conventional engines, hybrid vehicles and fuel cell powertrains are discussed. Fundamentals are revisited and advancements are highlighted. A comprehensive list of references is provided. 相似文献

Recent visual marking studies have shown that the carry-over of distractor inhibition can impair the ability of singletons to capture attention if the singleton and distractors share features. The current study extends this finding to first-order motion targets and distractors, clearly separated in time by a visual cue (the letter X). Target motion discrimination was significantly impaired, a result attributed to the carry-over of distractor inhibition. Increasing the difficulty of cue detection increased the motion target impairment, as distractor inhibition is thought to increase under demanding (high load) conditions in order to maximize selection efficiency. The apparent conflict with studies reporting reduced distractor inhibition under high load conditions was resolved by distinguishing between the effects of "cognitive" and "perceptual" load.

The role of psychologists as health care providers and the parameters of reimbursement for health care services are timely and controversial issues. A landmark decision was reached in this controversy in the 1980 appeal of a Virginia suit by clinical psychologists in which the court ruled that Blue Shield's refusal to directly reimburse psychologists was a violation of antitrust law. Thus, the requirement that psychologists bill through physicians was not upheld. In recent years a specific aspect of this controversy involved psychologists' roles in potential national health insurance programs. A limited study (appearing in the "National Register of Health Services Providers in Psychology" 1976-1978) of clinical psychologists' attitudes toward national health insurance suggests that Congress and psychologists may have disparate views. In addition to favoring national health insurance, over 85% of psychologists surveyed responded that consumers would benefit from such a program with mental health coverage. Only 16% agreed that such a program would constitute a subsidy of the rich by the poor (Albee, 1977). Several areas of conflicting or confusing responses in this study may reflect legitimate reasons for concern by Congress regarding institution of national health insurance. Belief that providers would benefit from mental health coverage in a national health insurance program was shared by 80% of respondents. Ninety-five percent of respondents identified the inclusion or exclusion of clinical psychologists in such a national health insurance as affecting the future of the profession. Curiously, over 50% of respondents agreed that primary care physicians should be reimbursed for mental health services, although such physicians have received no formal training in psychological services.

Raman microspectroscopy was used to determine biochemical markers during the differentiation of embryonic murine stem cells (mES) in vitro. Such markers are useful to determine the differentiation status of ES cells cultured on biomaterials. Raman spectra of mES cells as undifferentiated, spontaneously differentiated (4 days), and differentiated cells via formation of embryoid bodies (16, 20 days) were analyzed. Unsupervised hierarchical cluster analysis and principal component analysis were used to determine biochemical differences between mES cells in various states of differentiation. The undifferentiated cells were characterized by high scores of the first principal component (PC1, 49% variance). Similarity between the PC1 loading and the Raman spectrum of RNA indicated a high concentration of RNA in mES cells compared to differentiated cells. The ratio between the peak areas of RNA and proteins was used as a measure of mRNA translation. Using the same peak area ratio, it was possible to differentiate even between mES as undifferentiated and in early stages of differentiation (4 days). These findings were correlated with biological studies reporting high levels of nontranslated mRNA during early embryonic development. Therefore, the RNA translation obtained from the Raman spectra can be used as marker of differentiation state of mES cells. 相似文献

A technique that allows one to measure simultaneously the three velocity components in a fluid plane is presented. One obtains the quantitative information from only one holographic recording by combining two different reconstruction processes. As both processes use an interferometric comparison of two waves, we refer to this technique as dual holographic interferometry. The far-field fringe pattern that is obtained when reconstruction is made with an expanded laser beam allows one to determine the in-plane velocity components. The image-field fringe pattern that is obtained when a pointwise laser beam is used for reconstruction contains information about an out-of-plane velocity component. As the two reconstruction processes have different sensitivities, two different ways to combine them are proposed. The system has been demonstrated in a fluidlike solid object and in a convective flow. 相似文献

Initial validation data on the Counselor Rating Form—Short Version (CRF—S; J. D. Corrigan and L. D. Schmidt; see record 1983-09385-001), a revised version of the Counselor Rating Form (CRF; A. Barak and M. B. LaCrosse; see record 1976-07806-001), were positive. The present study, with 215 college students, largely replicated the methodology, and simultaneous collection of data on the CRF and the CRF—S allowed for direct comparisons between the 2 instruments. Results generally add to the validation of the CRF—S, but it was not successful in facilitating greater use of the lower end of the 7-point rating scale. Differences in counselor ratings suggest that the 2 instruments might be measuring slightly different constructs. (8 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

This study examined the congruence between conventional cutoff scores on the Beck Depression Inventory (BDI) and selected diagnostic classifications of the Research Diagnostic Criteria in a sample of 102 elders seeking psychological treatment. Only 16.67% were misclassified by customary BDI cutoff scores. Minor Depressive Disorders were less clearly identified than Major Depressive Disorders or nondepressed status. Similar results were obtained in a second sample of elders not seeking treatment. Findings support the utility of the BDI as a screening instrument for identification of clinically depressed elders.

The Federal Water Pollution Control Act of 1972, P.L. 92-500, requires tertiary treatment of all effluent by 1983; Oregon State policy focuses on maintaining future effluent discharges at a level no greater than current levels. The Federal and State policies are combined in planning for the future management of the quality of the Willamette River. As a consequence, the Willamette will be clean-too clean- and the economic inefficiency inherent in the water quality control plan will cause misallocation of public resources. This misallocation could be avoided by incorporating economic principles, especially cost comparisons and the consideration of alternative procedures, into the water quality plan. 相似文献

With the ascension of the Internet as an information resource, Web sites are likely to be the first exposure applicants have to specific programs. The authors evaluated professional psychology program Web sites for ethnic and sexual orientation minority content, discovering that diversity content of Web sites was considerably less than in previously examined paper application materials. Clinical psychology programs were more likely to state a commitment to diversity training while counseling psychology programs were more likely to state a diversity minor/track. School psychology programs had the lowest diversity content on their Web pages. This article explores how graduate psychology program Web sites communicate multicultural information and offers recommendations on using the World Wide Web as a cost-effective tool to attract a diverse student body.
