Theoretical study of Ar-MCO (M = Pd, Pt)
No full textAb initio calculations are performed for noble-gas complexes, Ar-PdCO and Ar-PtCO, by QCISD(T) with a Douglas-Kroll relativistic scheme. The electronic ground states of Ar-PdCO and Ar-PtCO are predicted to be 1Σ with linear equilibrium structure, and the binding energy of Ar is estimated as 5.3 and 8.2 kcal/mol for Ar-PdCO and Ar-PtCO, respectively. The M-C-O (M = Pd, Pt) bending frequency in MCO increases by ∼ 10% in Ar-MCO. The present calculations suggest that the experimentally reported M-C-O bending frequencies for MCO measured in the solid argon matrix are possibly to be assigned to the overtone band of the M-C-O bending mode of Ar-MCO
Asymptotic inference for nearly unstable AR(p) processes
No full textIn this paper nearly unstable AR( p) processes (in other words, models with characteristic roots near the unit circle) are studied. Our main aim is to describe the asymptotic behavior of the least-squares estimators of the coefficients. A convergence result is presented for the general complex-valued case, The limit distribution is given by the help of some continuous time AR processes. We apply the results for real-valued nearly unstable AR(p) models. In this case the limit distribution can be identified with the maximum likelihood estimator of the coefficients of the corresponding continuous time AR processes

Jamil Hospital to structuring position in compliance with competence requirements still low (25%), There is difficult to decide candidate whom eligible for the post in accordance with the competency, because they execute the structuring manually. One way out to reduce obstacles and to overcome this problem is using decision support system with AHP (Analytical Hierarchy Process). This method can help leaders to conduct the election candidates objectively, based multi criteria set. This research is a design engineering, built by attention to the feedback from users. Start from the planning, searching of data, analyzing, and designing using Object Oriented Design (OOD), tools to analysis by Data Flow Diagrams (DFD) , coding and subsystems that are designed last three combined into a DSS . In the construction phase, the author makes the design of the program by using the Visual Studio 6.0 with Microsoft Access database. The item is the reference of the election candidates, namely: education, rank, leadership training, office history, technical training, age, health, discipline/punishment, dedication/appreciation and courses
Ittijahat Abi Dhu'ayb Al-Hudhali fi Qasidatihi Ar-Ritsa’
No full textThis article aims to know Ittijahat of Abu Dhu’ayb Al-Hudhali in his poem of Ritsa’. Ittijahat in this study is a description of the poet's tendency to divide Ar-Ritsa', namely Nadb and Ta'ziyah. Ar-Ritsa 'is one of the various forms of Arabic poetry. To analyze the discussion problem, the author uses descriptive analysis method, because this method is very appropriate to find out the picture and state of a thing by describing it in as much detail as possible based on the facts found in the data in question. The results obtained are: In the beginning of the poem, he tends to mourn (Nadb) their five children. He describes in it that he does not stop crying and has trouble sleeping until he becomes weak emaciated due to the intensity of the grief, pain and worries that dominated in his pysche. As for the middle of the poem to the end, the poet turns to the consolation (Ta’ziyah) of his children’s death, as he reflects on the reality of life and death, the poet declares that death is inevitable for every human being that he must accept it and let it go, which the poet portrayed in the exciting narrative style. The story is divided into three stories: the zebra, the bull of the beast, and the two knights.</jats:p
Rayleigh number dependence of the Archimedes number dependent large-scale flow structure formation in mixed convection
No full textWe report on experimental investigations of large-scale flow structure formation in mixed convection. We characterize the flow field by measuring the velocity fields within a rectangular model room using 2D2C PIV. The control parameters are the Reynolds number Re, the Rayleigh number Ra and the Prandtl number Pr. All parameters are linked through the Archimedes number Ar. In 6.4x10-2 ≤ Ar ≤ 1.39x101, 4.2x103 ≤ Re ≤ 6.35x104 and Ra = 3.1x107, Ra = 1.8x108 and Pr = 0.713 we found flow 3 different flow structures. While keeping Ra and Pr constant and varying Ar through Re variations, we found an Ar dependence of the largescale flow structure formation within 6.4x10-2 ≤ Ar ≤ 1.39x101. Furthermore, we found a Ra dependence of the structure formation, which shifts the transition points between the structures to higher Archimedes numbers and reduces the mean velocities within the investigated domain
Nonlinear stories told by cups and saucers: Smart replic as with response 3D audio
No full textIn museum exhibitions historical objects are usually shown by visual display, in a showcase with extra textual information added to it. Museum visitors can never touch the objects, let alone use them. As a result, visitors ‘scan’ the displayed objects from a distance, something that needs reconsideration in our present time where the ‘experience’ is essential. To provide a way around this situation, the so-called ‘smart replica’ was proposed in the previous issue of Ar[t] (Roozenburg, 2012): a new kind of reproduction, in the shape of a 3D print, that stretches the boundaries of the replica’s concept as an autonomous object based on a historical artefact. New methods of access and new digitization strategies based on the study of the relationship between the ‘bits’ and ‘atoms’ are being developed. We hypothesize that by using these 3D imaging techniques the value of our cultural heritage can be increased. In other words, the goal is not to make the most realistic copy of the original, but to analyse, communicate and enhance those qualities of the historical artefact that are the most meaningful to us, now. Here we present the design project of Lotte de Reus in connection with this paradigm shift. Completed as a graduation project, it presents an auditory environment to augment the artefact in an unobtrusive and non-linear way. The objects that are central in this project are seven teacups and saucers that are part of the collection of Museum Boijmans Van Beuningen. These are currently on display in a new exhibition on design and pre-industrial design. Depicted in figure 1, each of these teacup and saucer sets represents a milestone in the Dutch history of porcelain. Starting with the first import of porcelain from China in the seventeenth century by the Dutch East Indies Company; followed by the invention of Delft’s blue as an attempt to copy Chinese porcelain, and ending with the small scale production of porcelain in the Netherlands.Design EngineeringIndustrial Design Engineerin
Mixed (Ar)
No full textA comparison of the adsorption efficiencies for Ar atoms on large
(N () clusters and N2 molecules on large
(Ar)n () clusters has been investigated by the pick-up
technique. Using mass spectroscopy, it has been shown that mixed
(Ar)n(N clusters can be created either by depositing Ar
atoms from buffer gas on the surface of (N clusters or by
depositing N2 molecules from buffer gas on the surface of (Ar)n
clusters. The composition of mixed (Ar)n(N clusters has
been determined as a function of cluster size and buffer gas pressure. The
adsorption efficiency for Ar on (N clusters is found to be
significantly higher than that for N2 on (Ar)n clusters. This
effect is attributed to the difference in Ar–Ar, N2–N2 and
Ar–N2 binding energies
Program “I’dad Lughowi” dalam Upaya Membekali Kemampuan Bahasa Arab Mahasiswa STIBA Ar-Raayah, Sukabumi
No full textNowdays, Arabic already has its own charm. Apart from the Al-Quran and Hadith as sources of Islamic Shari'a which are imported from the original source in Arabic, the emergence of scientific disciplines linked to Shari'a adds to the public's attraction and interest in studying Shari'a directly from its Arabic sources. Arabic language learning is starting to emerge with various strategies and methods applied. Some are successful and others need review. In this article, the author wants to examine Arabic language learning in the STIBA Ar-Raayah i'dad lughowi program which is considered successful because it has produced many regional, national and even international achievements. This article aims to examine the background of students in the STIBA Ar-Raayah i'dad lughowi program, the teaching and learning activities of the i'dad lughowi program at STIBA Ar-Raayah and the examination system implemented in the i'dad lughowi program. This article is a case study at STIBA Ar-Raayah using a descriptive qualitative approach. The results found in this research are (1) the background of students in the STIBA Ar-Raayah i'dad lughowi program who come from various regions and schools, (2) learning using the Arabiyyah book Baina Yadaik by maximizing the direct method and activities outside the classroom, (4) a unique exam system with Al-Qur'an exams, subject exams, syahri exams, nihai exams, as well as a rosib system for students who do not reach the minimum completion criteria. The results and conclusions of this research can be used as a reference for Arabic language educational institutions to make them more effective in the future
