Student Monitoring System in SMAN 2 Sidoarjo via Web and Mobile using XML Web Service

A student monitoring system which can be easily accessed by parent, is important in order to reduce student violations in school. In this final project, a monitoring system is developed in SMAN 2 Sidoarjo that can provide several information for parent about attendance, payment, score, schedules, violation list, and school activities. This system can be accessed by them trough internet, using mobile devices with Java technology or using web. To simplify the process of data exchange between server and client, this monitoring system is using XML Web Service. Client application (mobile and web) cannot access directly to the database, but by calling methods that provided by the XML Web Service. Using this student monitoring system, parent can quickly find out if their children's are doing violations in school. So they can control and guiding their children's not to do that again. Key words : XML, Web Service, J2M

Predicting productivity loss caused by change orders using the evolutionary fuzzy support vector machine inference model

Change orders in construction projects are very common and result in negative impacts on various project facets. The impact of change orders on labor productivity is particularly difficult to quantify. Traditional approaches are inadequate to calculate the complex input-output relationship necessary to measure the effect of change orders. This study develops the Evolutionary Fuzzy Support Vector Machines Inference Model (EFSIM) to more accurately predict change-order-related productivity losses. The EFSIM is an AI-based tool that combines fuzzy logic (FL), support vector machine (SVM), and fast messy genetic algorithm (fmGA). The SVM is utilized as a supervised learning technique to solve classification and regression problems; the FL is used to quantify vagueness and uncertainty; and the fmGA is applied to optimize model parameters. A case study is presented to demonstrate and validate EFSIM performance. Simulation results and our validation against previous studies demonstrate that the EFSIM predicts the impact of change orders significantly better than other AI-based tools including the artificial neural network (ANN), support vector machine (SVM), and evolutionary support vector machine inference model (ESIM)

PENDAMPINGAN DAN PELATIHAN PENGUATAN COMPUTATIONAL THINKING SEBAGAI KEMAMPUAN UTAMA ABAD 21

The skills needed in the 21st century are communication, collaborative, creativity innovation, and, critical thinking problem solving. One that is closely related to mindset is critical thinking problem solving. Critical thinking and being able to solve problems means the ability to understand a complex problem, connect information to other information, and finally find the solutions of the problem. This ability is closely related to the field of Information Technology (IT) because this field really needs a structured, coherent mindset, analysis, and computational thinking. This ability is very much needed by the young generation of Indonesia today. The Information Technology of UKDW Faculty (FTI)’s partner, Bopkri I Yogyakarta High School, has the same vision to prepare students to have real and applicable abilities. Students need regular and structured training to achieve these goals. Bopkri I and FTI work together in the form of community service training in strengthening computational thinking by implementing basic programming, advanced programming, and training evaluation.This program was held in 2 major stages., The first stage consists of strengthening computational thinking using basic programming training in general, and the second using advanced programming training in the form of competitive programming and its simulations. Students were given complete material, face-to-face/online knowledge transfer, complete modules, exercises, and direct simulations by some experienced lecturers from FTI UKDW

Deformation Capacity and Strength of RC Frame Members with High-Strength Materials

Some implications of using high-strength concrete and steel materials in reinforced concrete frame members are discussed in terms of both flexural design and behavior. Through an example, it is demonstrated that the computed sectional curvature is highly sensitive to the choice of rectangular stress block used to model compression zone stresses of high-strength concrete. Comparison of various models suggests that the use of the stress block model defined in the ACI Building Code tends to overestimate curvature for concrete strengths exceeding 12 ksi (83 MPa). In addition, recent test data are presented for flexure-dominated concrete members reinforced with high-strength steel bars. The effects of replacing Grade 60 (410) flexural reinforcement with Grade 100 (690) steel on deformation capacity, stiffness, and strength are examined. Test data support the viability of using Grade 100 (690) longitudinal reinforcement to resist loads that induce force-displacement response well into the nonlinear range

Strength and Deformation of Reinforced Concrete Squat Walls with High-Strength Materials

The behavior of reinforced concrete (RC) squat walls constructed with conventional- and high-strength materials was evaluated through tests of 10 wall specimens subjected to reversed cyclic loading. Primary variables included specimen height-to-length aspect ratio, steel grade, concrete compressive strength, and normalized shear stress demand. Specimens were generally in compliance with ACI 318-14. Test results showed that specimens containing conventional- and high-strength steel had similar strength and deformation capacities when designed to have equivalent steel force, defined as total steel area times steel yield stress. The lateral strength of walls with aspect ratios of 1.0 and 1.5 can be estimated using their nominal flexural strength when the nominal shear strength exceeds Vmn. For specimens with an aspect ratio of 0.5, the lateral strength was close to the force required to cause flexural reinforcement yielding and less than the nominal shear strength calculated per ACI 318-14. Specimen deformation capacity decreased as the normalized shear stress increased. The use of high-strength concrete, which led to a reduced normalized shear stress demand, resulted in larger specimen deformation capacity

Dynamic changes in Sox2 spatio-temporal expression promote the second cell fate decision through <i>Fgf4/Fgfr2</i> signaling in preimplantation mouse embryos

Oct4 and Sox2 regulate the expression of target genes such as Nanog, Fgf4, and Utf1, by binding to their respective regulatory motifs. Their functional cooperation is reflected in their ability to heterodimerize on adjacent cis regulatory motifs, the composite Sox/Oct motif. Given that Oct4 and Sox2 regulate many developmental genes, a quantitative analysis of their synergistic action on different Sox/Oct motifs would yield valuable insights into the mechanisms of early embryonic development. In the present study, we measured binding affinities of Oct4 and Sox2 to different Sox/Oct motifs using fluorescence correlation spectroscopy. We found that the synergistic binding interaction is driven mainly by the level of Sox2 in the case of the Fgf4 Sox/Oct motif. Taking into account Sox2 expression levels fluctuate more than Oct4, our finding provides an explanation on how Sox2 controls the segregation of the epiblast and primitive endoderm populations within the inner cell mass of the developing rodent blastocyst.

Large expert-curated database for benchmarking document similarity detection in biomedical literature search

Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency-Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research.Peer reviewe

Effects of horizontal web reinforcement on cyclic behavior of RC squat walls

This paper evaluates the effects of horizontal web reinforcement on cyclic behaviour of RC squat wall using test results of three pairs of specimens. One specimen was tested by the authors while the other five were adopted from the existing researches. Each specimen pair was designed with approximately the same design parameters, except that uniformly distributed horizontal web reinforcement was provided in one specimen only. Shear stress demand, evaluated based on the shear associated with the development of flexural strength at the base, was approximately 3.5f′c(psi) $3.5\sqrt {{{f'}_c}} (psi)$, 6.0f′c(psi) $6.0\sqrt {{{f'}_c}} (psi)$, and 8.0f′c(psi) $8.0\sqrt {{{f'}_c}} (psi)$, respectively, for each specimen pair. Test results show that specimen with uniformly distributed horizontal web reinforcement exhibited larger deformation capacity compared to specimens without it. Specimen peak strengths, on the other hand, appear to be similar with and without uniformly distributed horizontal reinforcement and can be satisfactorily predicted by nominal flexural strength
