The calculation of point quantity for lighting based on android OS using ionic framework and rule based expert system

At this time, the Covid-19 pandemic has not been finished so all activities and expenditure of funds must be economical. On the each building will be required electricity resources as a means for lighting the room. Reduced activities carried out outside the room make people carry out activities indoors, this results in a significant increase in electricity consumption for lighting. PT. PLN as the provider in Indonesia of electricity services for the community experiences a shortage of electricity resources and most of the electricity resources are used for lighting purposes. Indonesia as a developing country has a very large of population growth, so it requires many buildings as a place to live or a place of business and other activities. This paper will be discussion how a smartphone with an Android operating system can be used to determining the lighting requirements using the Ionic Framework and Rule Based Expert Systems. Using this application system, so electricity to lighting can be optimal and not too wasteful, which in turn can save on the use of electrical energy resources and can save of the cost.
Numerical Procedure for Predicting Pile Capacity—Setup/Freeze

In geotechnical engineering practice, the increase over time of pile capacity after installation is sometimes referred to as pile setup or freeze. Pile setup, which is often associated with piles driven into saturated clays and silts, is mainly attributed to soil consolidation around the pile. Field observations have shown that pile setup is significant and continues to develop for a long time after pile installation. Pile foundations are usually expensive. Therefore, taking a small percentage of pile setup into consideration will result in cost reduction and savings in piling projects. This paper presents a general numerical procedure to predict pile setup by simulating the behavior of the pile during its different life stages: installation, subsequent consolidation, and loading. The Hierarchical Single Surface modeling approach, the strain path method, and the nonlinear finite element analysis of porous media were used in the analyses. The procedure was verified by successfully predicting the field behavior of pile segment models installed into soft marine clay. Numerical experiments were also conducted to demonstrate the applicability of the numerical procedure to full-scale driven piles. Piles with diameters of 0.3 m and 0.5 m and a length of 10 m were considered in the analyses.
A Virtual Environment for Ship-Mounted Cranes

Abstract The authors present a virtual simulation of ships and ship-mounted cranes. The simulation is carried out in a Cave Automated Virtual Environment (CAVE). This simulation serves as a training platform for ship-mounted crane operators and as a platform to study the dynamics of ships and ship-mounted cranes under dynamic sea environments. A model of the (Auxiliary Crane Ship) T-ACS 4-6 was built, converted into an OpenGL C++ API, and then ported into the CAVE using DiverseGL (DGL). A six-degrees-of-freedom motion base was used to simulate the actual motion of the ship. The equations of motion of the ship are solved using the Large Amplitude Motion Program (LAMP), and the equations of motion of the crane pay load are numerically integrated; the interaction between the payload and the ship is taken into consideration. A nonlinear delayed-position feedback-control system is applied to the crane, and the resulting simulation is used to compare the controlled and uncontrolled pendulations of the cargo. Our simulator shows a great deal of realism and was used to simulate different ship-motion and cargo transfer scenarios.
Human density and sampling time explain richness of anurans in the brazilian biomes

Anuran richness patterns are strongly influenced by environmental factors. However, investigations on this issue have focused on the influence of abiotic factors without considering the joint effect of many existing variables, including the data sampling methodology and human demography. In this study we investigated the relationship between 21 environmental variables and anuran richness in brazilian biomes. Environmental variables represent a combination of human demographics, topographic, climatic and vegetation characteristics, and data sampling methodologies. We used principal component factorization and regressive and autoregressive models to select the most relevant variables for explaining anuran richness. Richness was correlated with demographic density, vegetation, accumulated rainfall, accumulated rainfall in the third and fourth quarter of the year, and accumulated rainfall in the first and second half of the year. However, the regressive and autoregressive models showed that human demographic density, sampling time, and sampling methodology were the best predictors of anuran richness. Our results highlight the importance of considering the effects of the human footprint and the methodology used for data collection on anuran species richness.

On the monitoring of trended and regularly adjusted processes

Trended and regularly adjusted processes are common in manufacturing industries. Such processes are, for example, related to tool wear, material replenishment or some regular maintenance. When the process has a slow trend or is frequently adjusted, the Shewhart chart can be interpreted in the same way as for a stable process. To facilitate comparison between such a trended and adjusted process to a stable case, and to estimate further the loss of effectiveness when the traditional Shewhart chart is applied to trended and adjusted process, this paper provides a statistical interpretation of traditional Shewhart charts for this type of processes. Formulas are derived for the calculation of alarm rate and average run length (ARL). This study is useful when deciding if a traditional Shewhart chart is sufficient or if a more advanced Statistical Process Control method is necessary. Furthermore, given the in-control and out-of-control ARL, a combined decision with regard to the control limits setting and the adjustment interval can be made. The general formulation is described and a simple linear trend model with an actual data set is used as an illustration.
Mobile robot localization using a light-stripe sensor

This paper presents an absolute localization system for a mobile robot moving on a flat ground, in a structured environment. The method makes use of 3D images provided by a light-stripe sensor. The images represent the sections in a horizontal plane of characteristic edges of the environment, whose model is known at the very outset. The goal is to extract at least two identifiable points out of the observed laser stripe and to determine the position and the heading of the robot considering a frame fixed at the observed edge. The experimental results obtained with an indoor mobile robot show that the localization errors are of the order of some centimeters in location and one degree in heading.
A waveguide-fed parallel plate slot array antenna

The authors propose an array in which a plane TEM (transverse electromagnetic) wave is excited in a parallel plate waveguide by a rectangular waveguide through feed slots cut in a back conductor. Its radiating part consists of an upper conductor plate in which a slot pattern has been etched. The configuration is suitable for linear polarization and dual-polarization use. The concept of a slot pair is adopted to suppress reflection and to maintain traveling wave antenna operation, which is confirmed by experiments. TEM plane wave excitation in the parallel plate waveguide has been confirmed, and the uniform aperture field distribution has been realized at the design frequency. <<ETX>>
Single-Phase Single-Stage Power-Factor-Corrected

Single-phase single-stage power-factor-corrected converter topologies are reviewed in this paper. The topologies discussed in the paper are related to ac-dc and ac-ac converters that are classified on the basis of the frequency of the input ac source, the presence of a dc-link capacitor, and the type of control used (resonant or pulsewidth modulation). The general operating principles and strengths and weaknesses of the converters, which the authors have investigated over the last decade, are discussed in detail, and their suitability in practical applications is stated. Con- sidering practical design constraints, it is possible to effectively employ many single-stage converter topologies in a wide range of applications.
The Sexual Function of Iranian Pregnant Women: a Systematic Review and Meta-analysis

Contex: Sexual function during pregnancy affects martial satisfaction of couples and increases empathy in the completion of pregnancy and women’s self-confidence with reduction in fears. Studies on the sexual function of Iranian pregnant women have shown controversial results. The present study aimed to review the sexual function of Iranian pregnant women. Methods: The international and national databases of Web of Science/ISI, PubMed, Scopus, MagIran, and SID databases using “sex”, “sexuality”, “sexual intercourse”, “sexual function”, “sexual dysfunction”, and “pregnancy” without a time limit. We included all the papers published in Persian and English reporting the mean score of sexual function of pregnant women. Based on the pre-designed form, the required data included the name of the first authors, year of publication, sample size, research setting, questionnaire type, and methodological quality, which were extracted and recorded. Data analysis was performed in STATA version 14 using a meta-analysis method and random-effects models. The heterogeneity of the studies was evaluated utilizing the I2 test. Results: In total, 11 articles with the total sample size of 2,657 were reviewed. The highest and lowest standard scores of sexual function were reported in the first pregnancy trimester (58.92%; 95% CI: 54.08-63.75) and the third trimester (47.70%; 95% CI: 23.18-39.56), respectively. In addition, publication bias was significant in the first (P=0.001), second (P=0.009), and third trimesters (P=0.014). Conclusion: The sexual function of women was found to reduce through pregnancy progress. Therefore, sexual function assessment and counseling on pregnancy care seem crucial for pregnant women.
Algorithms that compute test drivers in object oriented testing

Program testing has been a successfully established and implemented issue for the imperative paradigm. On the other hand, program testing for object-oriented (OO) is being constantly revisited and discussed. In this paper we present algorithms that compute the number of test drivers needed in testing OO systems. Testing OO programs would have been a done issue a long time ago if the imperative techniques were sufficient for that paradigm. However, more powerful and rigorous algorithms are significantly needed for OO programs since they differ in features and concepts than the imperative ones. In this study we have intended to make such a need, a primary goal.
Execution Failures in Retail Supply Chains - A Virtual Reality Experiment

We conduct a real-effort experiment in an immersive virtual environment in order to quantify the role of product similarity in execution failures in a retail setting. In our experiments, subjects must identify and sort two types of products based on their observable characteristics. When the two products are very similar, performance is substantially lower (with both more sorting errors and more products left unsorted) than when the products are more dissimilar. Introducing a clear visual cue to distinguish the products improves execution when the products are dissimilar (by lowering sorting mistakes) and, even more so, when they are similar (both by reducing sorting mistakes and the number of products unsorted). In the latter case the average increase in overall performance is over 22 percentage points. Our results suggest that there may be important gains from taking ease of execution into account in the design of products, product packaging, and labeling.
Operation Evaluation of the VEGGIE Food Production System in the Habitat Demonstration Unit

The 2010 Desert Research and Technology Studies (DRATS) of the VEGGIE Food Production System in the Habitat Demonstration Unit (HDU) Pressurized Excursion Module (PEM) was the first operational evaluation of salad crop production technology in a NASA analog test. A systematic evaluation of rooting media and nutrient delivery systems were evaluated for three lettuce cultivars that have shown promise as candidates for a surface based food production system. The VEGGIE nutrient delivery system worked well, was able to be maintained by multiple operators with a minimum of training, and supported excellent lettuce growth for the duration of the test. A Hazard Analysis and Critical Control Point (HACCP) evaluation was performed using ProSantm as sanitation agent prior to consumption was approved, and the crew was allowed to consume the lettuce grown using the VEGGIE light cap and gravity based nutrient delivery system at the completion of the 14-day DRAT field test. The DRAT field test validated the crew operations; Growth of all lettuce cultivars was excellent. The operational DRAT field testing in the HDU identified light quality issues related to morphology and pigment development that will need to be addressed through additional testing. Feedback from the crew, ground support personnel, and human factors leads was uniformly positive on the psychological value of having the crop production system in the excursion module. A number of areas have been identified for future work, to minimize the "footprint" of the Food Production system through creative use of unused wall and floor space in the unit.
Dynamic Interaction Analysis of a 2D Propulsion Shaft-Ship Hull System Subjected by Sea Wave

Since there is an evident tendency of development of large scale ships, the interaction between the propulsion shaft and ship hull becomes severe due to the tremendously increased ship size. As a result the reliability of the vessels has been put in an important position by the companies and the governments all over the world. The excited forces caused by severe sea waves have considerable effects on the hull deformation which could have further impact on the shaft propulsion system. This paper aims to investigate the coupling dynamics between the large ship propulsion system and hull subjected by sea wave in 2-dimensional circumstance. To look into the coupling mechanism between the ship propulsion shaft, hull and sea waves, a 2-dimensional novel model of large ship propulsion-hull coupling system is presented in this work to analyze the dynamic interactions of the ship propulsion system and hull. According to the dynamic equations of the coupling model, the dynamical responses of the ship shaft and hull are obtained under different stiffness of the support bearings. The analysis indicates that choosing the suitable stiffness of bearings have an important effect on the coupled system.Copyright © 2014 by ASME
Real Options Theory

The objective of this chapter is to present the real options theory (ROT) as an alternative methodology applicable to investment analyses in research and development projects (R&D). The authors intend to simulate the evaluation of an R&D project as a real option, compare real options theory outcomes to a conventional R&D project evaluation technique, and review real options theory as a trend in innovation project evaluation. The outcomes were compared to those obtained via the traditional net present value (NPV) method and a brief practical discussion regarding project management decision making is held. Finally, although ROT is still in a developmental and consolidation stage, the authors suggests that it can be used as a promising tool in the decision-making process concerning R&D projects. ROT is presented as a research field that would integrate a set of emerging management technologies, becoming a theoretical base for new tools and methods to support project management (PM) decision making.

Modelling of GaAs‐MMIC microstrip line up to 40 GHz

Modelling of MMIC multidielectric microstrip line on GaAs substrate for its precise characterization has been presented in this article. An accurate design database for the characteristic parameters of the microstrip line, namely, effective dielectric constant, characteristic impedance, and attenuation coefficient, has been generated using the spectral‐domain method (SDM). The accuracy of the developed database for the frequency range 1 to 40 GHz has been verified with the experimental results. On‐wafer measurements have been carried out to minimize the parasitic losses at the high frequencies and the effect of CPW‐pads has been de‐embedded from the measured S‐parameters to obtained accurate characteristic parameters of the microstrip line. The theoretical and the measured values of the characteristic parameters of microstrip lines show good agreement within 1% to 2%. This work is expected to be useful in GaAs foundries for accurate MMIC‐CAD modelling of microstrip lines up to 40 GHz. © 2004 Wiley Periodicals, Inc. Int J RF and Microwave CAE 14, 475–482, 2004.
Functional groups, determinism and the dynamics of a tropical forest

Unravelling the drivers of forests dynamics is one of the main challenges in tree community ecology. These drivers include niche differentiation, dispersal limitation and stochasticity. Previous work has demonstrated that these mechanisms likely interact such that no one process is responsible for forest dynamics. One possibility is that the functional composition in a forest changes in a deterministic fashion, but the abundances of individual species that are functionally similar and have similar life‐history strategies drift in a neutral fashion. This framework aligns with the functional group‐based version of the neutral theory proposed more than 30 years ago, but it has remained poorly understood and is not well‐integrated in tree community ecology. To investigate the possibility that determinism and neutrality may operate on the functional and species levels, respectively, we studied the long‐term dynamics of trees on Barro Colorado Island, Panama. Specifically, we sorted tree species into functional groups. We defined them as groups of species that cluster together based upon continuous functional trait measurements that are believed to reflect key life‐history trade‐offs. This information was then used to quantify the observed species and functional group dynamics in the forest and to compare them to that expected from neutral simulations. We found that forest dynamics are likely governed by deterministic processes at the between‐functional group level where species relative abundances change or drift through time within group. Species rank distributions for each functional group remained relatively stable suggesting that these groups may act as broad adaptive zones for both common and rare species that may promote species coexistence. Moreover, we found that these functional groups associate with different habitats in the forest. Synthesis. The results indicate that deterministic processes control the relative proportion of each functional group in the tropical forest studied and that individual species within groups may have apparently neutral dynamics. Furthermore, the results demonstrate that observed stable functional group relative proportions can be produced by deterministic or neutral dynamics, which underscores the importance of comparing the observed functional dynamics to that expected under neutral dynamics.
