Early texts on Hindu-Arabic calculation
No full textThis article describes how the decimal place value system was transmitted from India via the Arabs to the West up to the end of the fifteenth century. The arithmetical work of al-Khw¯arizm¯ı’s, ca. 825, is the oldest Arabic work on Indian arithmetic of which we have detailed knowledge. There is no known Arabic manuscript of this work; our knowledge of it is based on an early reworking of a Latin translation. Until some years ago, only one fragmentary manuscript of this twelfth-century reworking was known (Cambridge, UL, Ii.6.5). Another manuscript that transmits the complete text (New York, Hispanic Society of America, HC 397/726) has made possible a more exact study of al-Khw¯arizm¯ı’s work. This article gives an outline of this manuscript’s contents and discusses some characteristics of its presentation
Implications of the Improvement of Teaching Quality for Professional Development (PD) of Academics at the Colleges of Applied Sciences (CASs) in the Sultanate of Oman
No full textThe Oman Accreditation Council (OAC), which is called later the Oman Academic Accreditation Authority (OAAA), designed a higher education institution (HEI) Quality Assurance (QA) framework for Omani public and private Higher Education Institutions (HEIs), starting with a quality audit process in 2008. The Colleges of Applied Sciences (CASs), as a public HEI, are required to ensure the quality of all services and activities to meet particular national standards (specified in the framework) in order to gain a HEI and programme certificate. In line with a quality audit scope, the quality of the fields of PD and related teaching quality should be ensured and enhanced by the promotion and contribution of the former field to the maintenance and improvement of the latter one.
The chief purpose of this study was to identify the uptake and implications of the growing requirement to improve teaching quality and the PD of academics at the CASs in the Sultanate of Oman especially in the context of the application of the QA framework. The study focused on examining the academics’ participation in professional development programmes (PDPs) and current perceptions of PD with respect to the improvement of teaching quality improvement at these colleges. The current study also dealt with a reorganization and prioritization of academics’ PD needs, barriers to effective PD, and factors to enhance PD of academics regarding teaching quality improvement in the colleges.
Based on the purpose and research objectives, the current study adopted both positivist (quantitative) and interpretive (qualitative) research paradigms. Because the study perused quantitative and qualitative data regarding certain variables, it chose a mixed-research design. The researcher designed survey questionnaire to collect quantitative data and a semi-structured interview and a focus group discussion to probe and interpret quantitative findings. After fulfillment of the validity and reliability measurements, a self-completion questionnaire was distributed to a stratified random sample of academics (170) over the six CASs. A total of 150 questionnaires (out of 170) were completed and returned and the response-rate reached 88.2%. The quantitative data was analyzed by appropriate analysis using the Statistical Package for Social sciences (SPSS), while the qualitative data was analyzed by appropriate qualitative analysis.
The findings of the study showed that the level of academics’ participation in PDPs to improve teaching quality in the last two years in the CASs seems to be unsatisfactorily low. The current perceptions of the PD situations in the colleges, relating to teaching quality improvement, signified a shortage in the number of available PDPs and/or a discouragement of academics’ participation in these programmes in the last two years. The study also revealed all the 22 PD needs of academics regarding the improvement of teaching quality are significantly demanded by participants; the higher rated needs focused on a development of ‘student centred’ skills, such as critical thinking and problem-solving skills.
Furthermore, the study illustrated that the highest significant perceived barriers to effective PD in the CASs, as related to teaching quality improvement, focus on a lack of a clear institutional PD policy and a lack of appropriately systematic PD plans. The study also revealed all 10 perceived factors to enhance PD regarding teaching quality improvement are very important. The most significant factors represented and stressed particular problematic issues (the high rated barriers) and a reduction of a heavy workload to enhance academics’ participation in PD regarding the improvement of teaching quality.
Conclusions drawn from the discussion of the findings of study include a lack of a clear PD policy at national and institutional levels and absence of a particular authority/unit concerning PD issues in Omani HEIs. The two problematic issues resulted in a lack of systematic and realistic PD plans in the CASs, involving a lack of academics’ involvement in PD plans, a misconnection of academics’ PD needs to PD, inappropriate facilities and resources allocation, and inappropriate evaluation processes of PD. In addition, the conclusions also include that PD of academics regarding the improvement of teaching quality in the colleges requires more attention and focus to manage particular significant issues perceived by participants as both barriers and potential facilitators relating to PD of academics.
Based on identified conclusions, particular implications for policy and practice to enhance PD to improve teaching quality were set at three levels: governmental, institutional, and individual. Moreover, achievements of the current study according to the research questions were identified and contributions of the study to the fields of PD, teaching quality, and the context of QA and quality audit in HE were addressed. Based on the findings and conclusions, particular directions and recommended issues were suggested to be studied by further research to benefit the enhancement of PD and related teaching quality improvement

Additional financing and its forms and provisions: An applied study in Saudi banks / Mohammed Khalil M. Alshaikhi
No full textThis study deals with additional financing, its forms and their legal description and the
Shariah rules applied to it. The existing problem dealt with here consists in that noncompliance
with the Shariah rules in these types of financing could lead to dilemmas
and negative impacts that can only be avoided through compliance with the rules and
regulations which in turn will make it efficient and positive. The researcher attempts to
introduce the additional financing and its types and also to show its position in the people
life in addition to emphasising the importance of following the Islamic teaching in the
light of the Shariah objectives in these types of finance. The methods of personal
additional financing from the financer bank or other and its applications in the Saudi
banks will also be discussed in order to clarify its rules and regulations in the Shariah.
The researcher is also going to talk about the real estate additional financing programme
and explain the types of financing that the banks offer in order to arrive to its rules and
regulations. In order to achieve these goals, the researcher applies the inductive method
in collecting the research materials and the descriptive method in discussing the issues.
The author also applies the analytical method to show the sense of the research and its
dimensions as well as the applied method to examine financing concept in a real environment in the studied country, Kingdom of Saudi Arabia. All the above was to
approach the subject from a the integral approach which the writer used to reach the
following results: the existence of an obligation to pay the first debt or any portion of it
from the additional financing invalidates the transaction, (2) non-delivering the goods
to the customer could affect the transaction, (3) combination of the two contracts of real
estate additional financing is acceptable even they are opposite because the financers
are separated. The researcher recommends the Islamic financial institutions to avoid
anything that can deceptively oblige the customer to pay the debt from the outcome of
the additional financing and also strengthen the alternative product financing such as
postponing settlement of additional financing till the payment of the fundamental
financing made and support such product. The institutions are also advised to
harmonise profit and non-profit services to achieve the Islamic objectives, benefit people
and establish the Shariah in the land
Prime-sized multilevel flash memory with non-binary LDPC
No full textThesis: M. Eng., Massachusetts Institute of Technology, Department of Electrical Engineering and Computer Science, 2018.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (pages 65-67).Flash memory companies are increasing the number of bits per cell to obtain higher information capacity per cell, starting from 1 bit/cell and going to 4 bits/cell recently. This scaling is enabled by the advancements in flash semiconductor technology, specifically the Bit Cost Scalable (BiCS) technology. However, capacity per cell scaling comes with performance, reliability, and endurance challenges. The industry has only used integer number of bits per cell, which makes the tradeoff between the capacity and the other system features less flexible than using fractional bits. This project explores programming 13 levels of charge ( 3.7 bits) into a QLC flash cell that normally carries 16 levels of charge (4 bits). We evaluate the 13-ary scheme against the 16-ary one and we show that the 13-ary has the same reliability at a lower SNR as the 16-ary, or the 13-ary has higher reliability than the 16-ary at the same SNR. We design binary and non-binary Quasi-Cyclic LDPC codes and implement Belief Propagation decoders for them.by Mohammed Al Ai Baky.M. Eng
