Peripheral arterial disease (PAD) affecting the femoropopliteal artery (FPA) is usually due to a chronic atherosclerotic obstruction that reduces blood flow to the lower limb. FPA stenting is an increasingly popular minimally invasive procedure that uses self-expanding nickel-titanium alloy (NiTi) stents. Benchtop mechanical stent testing allows direct evaluation of the device without interference from patient-dependent factors. The purpose of this study is to provide a ranking for different models of FPA stent that are frequently used to treat blocked FPA by applying the pictorial selection method for the criterion of variable mechanical load modes that were carried out in the experimental research studies. The results ranking of the FPA stent models was the first ranking position for SMART Control (Model I) with a net score of 3.65, the second model rank was for Complete SE (Model II) with a net score of 3.55, then SMART Flex. (Model III) with a net score of 3.40, and the classification of the last stent model was with a net score of 2.25, 2.20, and 2.10 for each one of Innova (Model X), Zilver (Model XI), and Viabahn (Model XII), respectively. There was none study has ranked the FPA stent models based on the mechanical criteria, which evaluate the mechanical performance for each stent.
In statistics copulas study and their applications are growing field which are very efficient functions in statistics and specially in statistical inference. Copula is used for constructing families of bivariate and multivariate distributions and a way of studying measure of dependence structure also, this copula couple multivariate distribution functions to their one-dimensional marginal distribution functions, which are uniformly distributed in [0,1]. They are several methods for constructing copulas as inverse method, Rüschendorf’s method, geometric method, algebraic method, and Archimedean method hence, we construct new copula according to univariate function. Copulas have appeared in many important fields such as civil engineering, biomedical studies, physics, quantitative finance, economics, climatology, social science, and insurance risk management which confirms its importance. This paper introduces some bivariate copulas as product, Clayton, Frank, Ali-Mikhail-Haq, Farlie-Gumbel-Morgensten, and Gumbel-Hougaard copulas. A new class of bivariate copula is introduced which depending on a univariate function. The basic properties which satisfied that is a true copula namely, the boundary conditions and the 2-increaing property are proved. Several properties of this class are studied as concordance ordering, dependence, symmetry, and measures of association. Further, example is proposed generated by a univariate function that described parametric family of copula as product copula.
The Synthetic Unit Hydrograph time to peak model is indispensable in determining the design of water infrastructure in Indonesia, given the many immeasurable watersheds that do not have rainfall and discharge data in determining the design in an area. The typical Indonesian peak time models that have been developed include Gama I, where several other Shyntetic Unit Hydrograph (SUH) still adopt models developed based on watersheds that are not in Indonesia. The Time Peak Model developed in this study will consider several parameters including the area of the watershed (A), the length of the main river (L), the length of the river from the center of the watershed to the outlet (Lc), river slope (S), watershed roughness (n). watershed form factor (Fb), river branching factor (RB), river length factor (RL), and Fractal Dimension (DF). This parameter will be compared with the time peak obtained from the hydrograph calculation of the observation unit using the Collins method. To calculate the hydrograph, the observation unit requires rainfall and discharge data. Meanwhile, to obtain these parameter values, a topographic map, a Digital Elevation Model (DEM) map, and a land use map are needed as well as the help of ArcGIS, Hec-RAS, AutoCAD, and Microsoft Excel software. Rainfall analysis will be tested by RAPS, stationary test, and outlier test, while the discharge data is stationary test and outlier test. The results of research from 10 watersheds spread across Java and Sulawesi obtained peak time (Tp) 3-5 hours, peak discharge (Qp) 1.89-39.93 m3 / s, watershed area 40.62 - 1376.75 km2; length of the main river (L) 24.95-106.48 km; the length of the river from the center of gravity of the watershed to the outlet (Lc) 5.45 - 32.99 km; river slope (S) 0.004-0.138; Watershed roughness (n) 0.035-0.048; watershed form factor (Fb) 0.04-0.70; river branching factor (RB) 3.05-40.51; river length factor (RL) 2.47-6.74; Fractal Dimensions (DF) 0.94-1.85. The results showed that the parameter L had the highest correlation rate followed by parameters A, RL, Lc, RB, DF, S, n and
Each community or group has local wisdom that is different from one to another. This is because local wisdom was born driven by the needs of the group in interacting with its environment, the natural surroundings, the groups that interact with it, as well as with group members. Forms of local wisdom can be either material or immaterial in the form of patterns of action or cultural outcomes. This research will raise local wisdom from one of the community groups in Indonesia, namely the Riau Malay community with local wisdom in the form of oral literature, in this case, Pantun. Therefore, this study will discuss the Pantun of the Riau Malay community as one of the local wisdom in Indonesia.
Information communication technology (ICT) helps the organisation to store and transmit information and this changes the organisations business processes. The ICT readiness model is a measurement tool proposed to measure how the organisation take advantage of ICT. The current ICT readiness models use factors such as software, hardware, technology, business process, human resource and other factors to measure ICT readiness in the organisation. These models do not classify which readiness factors do not change over time even though the technology evolve and change. Therefore, this study classified the ICT readiness factors into static and dynamic to better measure ICT readiness even after the technology evolves in the future. The proposed model was verified by 11 experts from the academic and industry. Most of the experts agree that the legal environment, cultural infrastructure and people and human resource as the static factors. While the dynamic factors consist of ICT infrastructure, technology and hardware, software, management and organizational, business process, ICT strategy, plans and policy, and security. The new ICT readiness model was verified and refined based on the experts' agreement and disagreement on these factors as described in this paper.
