Combinatorial problems in solving linear systems
No full textNumerical linear algebra and combinatorial optimization are vast
subjects; as is their interaction. In virtually all cases there should
be a notion of sparsity for a combinatorial problem to arise. Sparse
matrices, therefore, form the basis of the interaction of these two
seemingly disparate subjects. As the core of many of today's numerical linear
algebra computations consists of sparse linear system solutions, we
will cover combinatorial problems, notions, and algorithms relating to
those computations.
This talk is thus concerned with direct and iterative methods for sparse
linear systems and their intercation with combinatorial optimization.
On the direct methods side, we discuss matrix ordering; bipartite matching
and matrix scaling for better pivoting; task assignment and scheduling
for parallel multifrontal solvers. On the iterative method side, we discuss
preconditioning techniques including incomplete factor preconditioners
(notion of level of fill-in), support graph preconditioners (graph
embedding concepts), and algebraic multigrids (independent sets in
undirected graphs).
In a separate part of the talk, we discuss methods that aim to exploit
sparsity during linear system solution. These methods include block
diagonalization of the matrix; efficient triangular system solutions
for right-hand side vectors of single nonzero entries. Towards the
end, we mention, quite briefly as they are topics of other invited
talks, some other areas whose interactions with combinatorial
optimization are of great benefit to numerical linear algebra. These
include graph and hypergraph partitioning for load balancing problems,
and colouring problems in numerical optimization. On closing, we
compile and list a set of open problems
New Models for Data Envelopment Analysis. Measuring Efficiency Outwith the VRS Frontier
No full textSome models are presented in this paper which extend the concept of measuring superefficiency to the useful case of variable returns-to-scales (VRS), thus enabling the ranking of efficient as well as inefficient units. Two models, namely the Universal Radial Model and the Universal Additive Model, are presented that also have strong invariance properties (units and translation invariance). For both of these models a method for normalising the efficiency scores on a (0-1+) scale is presented. These models have been implemented in a software package and applied to the ranking of units in an industrial context.Data envelopment analysis (DEA), Superefficiency, Universal models
REVEALING PROCESS-BASED AND WRITERS’ CHOICE OF ACADEMIC ESSAY WRITING IN UNDERGRADUATE EFL LEARNERS
No full textThis research are to describe the process-based academic writing plays the role in essay creationin the argumentative essay from EFL learners; to describe the writer’s choice contributing in academic essay writing of EFL in undergraduate by using rhetorical patterns; and to describe the weaknesses and strengths of process-based and writer’s choice role; This research uses the descriptive qualitative. The data sources of this research are argumentative essays from ELTD, sixth semester in undergraduate IAIN SNJ Cirebon. The text was taken from the students who followed GBL lesson in previous semester. The instrument is the researchers theirself. The techniques of collecting data that is used by the researchers are questionnaire, interview transcript, audio recording and document. The result of this research is different with the previous research. In this research, the researcherss shows essay’s writing process in detail, contribution of rhetorical patterns in essay’s creation and how strength and weakness the process also the pattern in essay. To the role of process-based stages here are more than half of efforts in making essay, means certain stages are very useful to the students as the author here. The examples are pre writing, editing and revising, and responding. Then, the patterns help the students as the author to arrange their essay. Both are giving big contribution to communicate the text to the readers. This is such as using marker (Mk 1, Mk 2 and Mk 3) as the signal or bridge among the sentence or the paragraph. However, both of them still have their own to be applied to the EFL learner
Komunikasi Organisasi Pemimpin Dalam Membangun Kineja Aparatur di IAIN Pekalongan Tahun 2019-2020
No full textThe purpose of this research is to find out how much influence the leader communication has to the apparaturs in realizing the mission of the institution in IAIN Pekalongan. The method used is a qualitative field with a case study approach. The case study that the author is doing is intrinsic, the research will focus on organizational communication activities carried out by the leader to the apparatus in the IAIN Pekalongan environment. While data collection using sampling with data analysis study is holistic. Holistic analysis is needed by the writer to describe in detail the communications, the context of the communication, and the setting in which the communication takes place. The result of this research is that organizational communication is carried out on the principles of kinship and culture. This concept encourages the realization of harmonious conditions in the staffing environment of IAIN Pekalongan. Cultural principles are realized in the form of Asah, Asih, and Asuh between the leadership and the apparatus under them. These three principles appear in every formal and non-formal activity, including workshops, Trining, FGD, seminars, istighosah, autbond, dies natalis, and others. Meanwhile, the family principle is realized in daily interactions both in the office and outside the office. Organizational communication by the leader to the apparatus in the IAIN Pekalongan environment is able to encourage the realization of the institution's Vision and Mission

EPISTEMOLOGI AYAT MUTASHĀBIHĀT: Analisis Kaidah Nafiy pada Surah Āli ‘Imrān Ayat 7
No full textThis study aims to analyze the mutashābihāt verse in surah Āli ‘Imrān verse 7 through the perspective of Nafiy (negation) rules in order to understand its epistemological implications. Mutashābihāt verses, which contain implied meanings and multi-interpretations, often result in challenges to the interpretation of the holy verses of the Qur'ān. In Surah Āli ‘Imrān verse 7, Allah Swt. confirms the existence of clear verses (muḥkamāt) and vague verses (mutashābihāt), and states that Allah is the only one who knows the true meaning of the mutashābihāt verses. Using the rule of Nafiy, this study seeks to describe how the rejection or negation of certain meanings helps in understanding and interpreting mutashābihāt verses. This approach also examines how the method affects the formation of knowledge and understanding in the context of Islamic scholarship. The analysis shows that the Nafiy rule plays a significant role in maintaining the integrity and consistency of interpretation, as well as in guiding Muslims towards a deeper and more accurate understanding of divine revelation. The author hopes that this research can make a meaningful contribution to the study of Qur'anic interpretation and Islamic epistemology. Penelitian ini bertujuan untuk menganalisis ayat mutashābihāt melalui perspektif kaidah Nafiy (negasi) yang tercamtum dalam Q.S Āli ‘Imrān ayat 7 guna memahami implikasi epistemologisnya. Ayat mutashābihāt, yang mengandung makna tersirat dan multiinterpretasi, sering kali mengakibatkan tantangan terhadap penafsiran ayat-ayat suci Al-Qur’an. Dalam Q.S Āli ‘Imrān ayat 7, Allah SWT menegaskan adanya ayat-ayat yang jelas (muḥkamāt) dan ayat-ayat yang samar (mutashābihāt), serta menyatakan bahwa hanya Allah satu-satunya yang memahami makna yang sebenarnya dari ayat-ayat mutashābihāt tersebut. Dengan menggunakan kaidah Nafiy, penelitian ini berusaha menguraikan bagaimana penolakan atau negasi terhadap makna-makna tertentu membantu dalam memahami dan menafsirkan ayat-ayat mutashābihāt. Pendekatan ini juga mengkaji bagaimana metode tersebut mempengaruhi pembentukan pengetahuan dan pemahaman dalam konteks keilmuan Islam. Hasil analisis menunjukkan bahwa kaidah Nafiy berperan signifikan dalam menjaga integritas dan konsistensi penafsiran, serta dalam membimbing umat Muslim menuju pemahaman yang lebih mendalam dan akurat terhadap wahyu Ilahi.
Mobile-Based E-Sociometry Application Development at the Counseling Guidance Laboratories of the State Islamic Institute (IAIN) Bukittinggi
No full textSociometry is something that can be used in studying the structure of social relations among a group of individuals on the basis of research on social relations and social status of each member of the group concerned. Currently the service of sociometric instruments in the guidance and counseling laboratory of the Bukittinggi State Islamic Institute is still using conventional techniques using Ms.Excel. It is done manually using the distribution of questionnaires, Ms.Excel, which is still combined with Ms.Acces, which is not online yet , so that it can only be distributed in labor, and the next problem is that the application that uses Ms.Excel cannot yet display sociometric reports graphically. The research method that the author uses is the R&D Research & Development method with a waterfall SDLC (System Development Life Cycle) system development model consisting of the Communication.Planning.Modeling stages. Construction.Deployment. For the product test that the author did, the results obtained: the validity test by the validator obtained a value of 0.85 with valid criteria, the practicality test by the practitioner obtained a value of 0.83 with the Very Practical criteria, and the effectiveness test by the effectivator obtained a value of 0.75 with the Very Effective criteria
