A new active R bandpass filter     

Ahmed M. Soliman  Mahmoud Fawzy 《Journal of The Franklin Institute》1978,306(2):159-163

A new active R filter which realizes a second order bandpass transfer function is given. The network employs only resistors and two operational amplifiers. Sensitivities to all passive and active circuit components are very low. Design equations are given and experimental results are also included.  相似文献

Availability of Education and Training for Medical Specialists about the Impact of Dementia on Comorbid Disease Management     

Joseph Elias Ibrahim 《Educational gerontology》2013,39(12):925-941

Individuals with dementia carry an additional health burden of multiple comorbid conditions. Effectively assessing and treating these comorbid conditions requires the medical specialist to be aware of, understand, and manage the effects of dementia on their clinical subspecialty practice. This ecological study describes the dementia-related education available to medical specialists in Australia outside the domains of geriatrics, neurology, and psychiatry. The dementia-related content of specialist medical training curricula and dementia-related information published in high-impact medical journals between 2000–2012 was reviewed. Dementia-related education was found to be absent from the training curricula for 14 of the medical specialties within Australia. And less than 0.10% (1,921 articles) of the more than two million articles published in the 138 journals assessed were dementia related.  相似文献   

An analysis of the social impact of the stipend program for secondary school girls of Khyber Pakhtunkhwa     

Vaqar Ahmed  Muhammad Zeshan 《Educational Research for Policy and Practice》2014,13(2):129-143

The present study carries out an impact analysis of a conditional cash transfer (CCT) program for secondary-school girls in seven districts of Khyber Pakhtunkhwa province in Pakistan, including Battagram, Bonair, Hangu, Kohistan, Shangla, Tank, and Upper Dir. In 2012 we collected household-level primary data and used a probit model for quantitative analysis. Further, we conducted various focus group discussions and key informant interviews in the target areas. Results show that the chances of female schooling decrease with a rise in family size. The chances of female education increase by 1.8 and by 3.3 % if household heads and their spouses have one additional year of schooling, respectively. Better educational services and rises in family income increase the chances of female ecucation by 11 and 0.3 %, respectively. Finally, socioeconomic awareness, improved economic conditions, and CCTs increase the chances of female education by 5.2, 4.7, and 0.03 %, respectively. Overall, the stipend program (CCTs) shows a pareto improvement. Our results indicate that 35 % of girls will drop out in the absence of a stipend program. The present study recommends that to increase program effectiveness, local-level monitoring and program evaluation may be improved, delays in stipend payments to female students should be reduced, a grievance redressal mechanism for parents and guardians should be introduced, and clear synergies should be developed with other transfer programs.  相似文献   

Quantum-Inspired Blockchain-Based Cybersecurity: Securing Smart Edge Utilities in IoT-Based Smart Cities     

Ahmed A. Abd El-Latif  Bassem Abd-El-Atty  Irfan Mehmood  Khan Muhammad  Salvador E. Venegas-Andraca  Jialiang Peng 《Information processing & management》2021,58(4):102549

Blockchain plays a vital task in cybersecurity. With the exerted efforts for realising large-scale quantum computers, most current cryptographic mechanisms may be hacked. Accordingly, we need a quantum tool utilised for designing blockchain frameworks to have the ability to be executed in the level of digital computers and resist the probable attacks from both digital and quantum computers. Quantum walks may be utilised as a quantum-inspired model for designing new cryptographic algorithms. In this paper, we present a new authentication and encryption protocol based on quantum-inspired quantum walks (QIQW). The proposed protocol is utilized to build a blockchain framework for secure data transmission among IoT devices. Instead of using classical cryptographic hash functions, quantum hash functions based on QIQW are employed for linking blocks of the chain. The main advantages of the presented framework are helping IoT nodes to effectively share their data with other nodes and full control of their records. Security analysis demonstrates that our proposed protocol can defend against message attack and impersonation attacks, thus ensuring secure transmission of data among IoT devices.  相似文献

A Qualitative Student Evaluation of Group Learning in Higher Education     

Ahmed Hassanien 《Higher Education in Europe》2007,32(2-3):135-150

The importance of group learning has increased significantly in higher education in the past two decades (Houldsworth and Mathews, 2000 Houldsworth, C. and Mathews, B. P. 2000. “Teaching Group Process Skills to MBA Students: A Short Workshop”. Education + Training, 42(1): 40–53.  [Google Scholar]). The primary focus of this study is to explore the feelings and experience of students regarding group work and group assessment in higher education. The study is exploratory based on a qualitative focus group approach. Interestingly, students felt that group work is a significant method to foster the development of critical thinking through discussion, clarification of ideas, and evaluation of others' ideas. Students consider “poor communication” and “poor attendance at group meetings” as the main challenges they face when working within a group. Also, students identified “dedicated assignment seminars” as the most effective tool, which could be used to enhance the effectiveness of group work. This study reinforces the findings of previous research into group work suggesting that the experience is a generally positive one for students. Results are discussed in the context of current theoretical and empirical work on group‐based learning, education implications and areas for further research are discussed.  相似文献   

Evaluation of genetic potential of the polyvoltine silkworm （Bombyx mori L.） germplasm and identification of parents for breeding programme     

Rao CG  Seshagiri SV  Ramesh C  Ibrahim Basha K  Nagaraju H  Chandrashekaraiah 《Journal of Zhejiang University. Science. B》2006,7(3):215-220

In the present study, polyvoltine germplasm stock ofAndhra Pradesh State Sericulture Research and Development, Institute （APSSRDI） was evaluated for its performance based on quantitative and qualitative traits. Twenty-one oval and 10 peanut cocoon shaped lines were reared in different seasons of the year. Since the polyvoltines are non-diapausing, six generations were reared and evaluated for various economically important traits based on evaluation index and sub-ordinate function statistical methods. Ten top ranked lines obtained by using both the methods were identified as potential parental strains. Among oval lines, APMI4, APMI 1, APMIS, APMW9, and APMI9, and among peanut lines APMD5, APMDI, APMD3, APMD9 and APMD8 were selected as base material. The identified high yielding lines will be used in various breeding programmes as initial parents for the synthesis of superior polyvoltine breeds/hybrids.  相似文献
