TL;DR: The main objectives of this paper are to uncover the constraints and limitations by an in-depth literature review and to recommend ideas to address them, including some ideas for monitoring the integrity of map matching algorithms.
Abstract: Map matching is a technique combining electronic map with locating information to obtain the real position of vehicles in a road network. Map matching algorithms can be divided in real-time and offline algorithms. Real-time algorithms associate the position during the recording process to the road network. Offline algorithms are used after the data is recorded and are then matched to the road network. Real-time applications can only calculate based upon the points prior to a given time (as opposed to those of a whole journey), but are intended to be used in 'live' environments. This brings a compromise of performance over accuracy. Offline applications can consider all points and so can tolerate slower performance in favour of accuracy. The MM algorithms integrate positioning data with spatial road network data to identify the correct link on which a vehicle is travelling and to determine the location of a vehicle on a link. A map-matching algorithm could be used as a key component to improve the performance of systems that support the navigation function of intelligent transport systems. A number of map-matching algorithms have been developed by around the world using different techniques such as topological analysis of spatial road network data, probabilistic theory, fuzzy logic, and belief theory. The performances of these algorithms have improved over the years due to the application of advanced techniques in the map matching processes and improvements in the quality of both positioning and spatial road network data. However, these algorithms are not always capable of supporting intelligent transport system applications with high required navigation performance, especially in difficult and complex environments such as dense urban areas. The main objectives of this paper are thus to uncover the constraints and limitations by an in-depth literature review and to recommend ideas to address them. This paper also presents some ideas for monitoring the integrity of map matching algorithms. The map-matching algorithms considered in this paper are generic and do not assume knowledge of ‘future’ information (i.e. based on either cost or time). Clearly, such data would result in relatively simple map-matching algorithms.

TL;DR: The results revealed that the fish assemblage in the river was clearly shifted in the number of species, the percents of exotic and marine species and the dominancy species compared with the previous status.
Abstract: Shatt Al-Arab River suffered from deterioration in water quality due to seawater intrusion as a result of the decline in rate of discharge of freshwater during the recent years. Therefore, the fish assemblage structure in the river was assessed using taxonomic and functional metrics of assemblage structure during the period from November 2015 to October 2016. Fish were sampled monthly by different fishing gears including gill nets, cast net and electro-fishing from three sites on the river. The fish assemblage consisted of 111 fish species representing 50 families belong to Osteichthyes except three relate to Chondrichthyes. The fish fauna comprised 15 native, 13 exotic and 83 marine species. The most abundant species were Carassius auratus (13.24%), Oreochromis aureus (12.58%) and Planiliza klunzingeri (10.56%). The dominance value (D3) was 63.4%. The resident species formed 36.0%, occasional species 55.9% and seasonal species 8.1% of the total number of fish species. Fish diversity index ranged from 1.62 to 2.22, richness from 2.23 to 4.63 and evenness from 0.40 to 0.64. Canonical correspondence analysis indicated that water temperature and salinity correlated positively with the number of species. The results revealed that the fish assemblage in the river was clearly shifted in the number of species, the percents of exotic and marine species and the dominancy species compared with the previous status.

TL;DR: In this article, the authors have discussed the effect of moisture on the amount of swell and shrinkage in clays in general and expansive soils in particular, and how these volume changes finally result in serious damage to the various structures including pavements.
Abstract: Clays in general and expansive soils in particular have been a major concern to geotechnical engineers for many years. Moisture variations produce big volume changes in these types of soils. Several factors like amount and type of clay minerals, soil structure, dry density, confining pressure, moisture content and climate changes influence the amount of swell and shrinkage. These volume changes finally result in serious damage to the various structures including pavements. In addition, clayey soils are usually stiff when they are dry and give up their stiffness as they become saturated. Soft clays (i.e. illite/kaolinite/ montmorillonite) are associated with low compressive strength and excessive settlement. This reduction in strength due to moisture leads to severe damages to buildings and foundations.

Abstract: Indonesia with raw material limestone abundant, light brick of Autoclaved Aerated Concrete (AAC) is the most important component in the construction of buildings, so that needs light brick AAC qualified in mechanical and thermal properties of acoustic. In the research domain lightweight brick lifting who qualified mechanical properties. Advantages of light brick AAC low density of about 500 to 650 kg/m3, more economical, suitable for multi-storey buildings can reduce the weight of 30 to 40 % compared with conventional brick (clay brick). One of the problems found in the fabrication of lightweight brick is how to determine the composition of raw materials used. The composition of materials in lightweight brick can affect its mechanical properties which are an important parameter for building materials. In this research the prediction of the effect of elements composition and density on compressive strength (AAC) using neural network has been done. Furthermore, the simulation on the effect of each element composition and the density on compressive strength also have been done. The best network developed in this research using feed forward back propagation architecture and Levenberg-Marquardt algorithm is to use 8 hidden nodes, with MSE (mean square error) training of 0.001605667 and MSE validation of 0.01455. Simulation results show that composition of Ca, Si, O, and density are all directly proportional to compresssive strentgh, while composition of Al is inversely proportional. The compressive strength prediction results obtained for 4 AAC, and for sample AAC-a = are 4.80 MPa, AAC-b= samples 5.24 MPa, AAC-c=3.23 MPa, and AAC-d= 3.67 MPa. The result of prediction shows that the neural network developed can predict the effect of composition and density on compressive strength of AAC.

TL;DR: In this article, the authors used an exploratory method to construct the development of sustainable community's food barn and found that the inactive food barn was caused by its poor management while the active food barn functioned for savings and loans of rice grains.
Abstract: Food storage in the form of barn is mostly ineffective in Wonogiri. Even though, it has very significant role as buffer stock in the drought season. Meanwhile, the government’s program initiates the activating of food barn, by providing fund assistance for barn building, rice miller and restock rice grains in the barn. However, it has not made the barn well developed, due to its dependency on the program. The aim of this study is to construct the development of sustainable community’s food barn. This study was used an exploratory method. The location of this study was selected purposively in Wonogiri. The result of this study showed that inactive food barn was caused by its poor management. Meanwhile, the active food barn functioned for savings and loans of rice grains. It has high dependency to the government program. The barn development needs a support from physical and non-physical environment to reach its sustainability.

TL;DR: In this paper, the effect of the number and diameter of the Savonius blade wind turbine with an additional concentrator was evaluated at lower wind speeds of 2-5 m/s.
Abstract: Savonius turbine is a type of vertical-axis wind turbines. The turbine has a potential to be developed as it has a simple construction and is suitable for low wind speeds. However, the turbine is still rarely used because of the low efficiency of the turbine compared to other turbines. The low efficiency of the turbine is due to the negative moment. Some efforts have been done to reduce the negative moment such as by adding a wind concentrator. The wind concentrator can steer the incoming wind toward the turbine blades that generate positive moments, consequently, the generated power increases. The aim of this research is to determine the effect of the number and diameter of the Savonius blade wind turbine with an additional concentrator. The concentrator had a concentration ratio of 6:1 and it was tested at the lower wind speeds of 2-5 m/s. The result shows that adding a wind concentrator can increase the rotational speed of the rotor, power coefficient, and the turbine power. The Savonius turbine with two blades has the best performance compared to the three and four blades. The Savonius blade wind turbine with the rotor diameter of 12 cm is the best Savonius turbine for the concentration ratio of 6:1.

TL;DR: An efficient, reproducible and rapid protocol for in vitro mass production of Cymbopogon schoenanthus subsp.
Abstract: Cymbopogon schoenanthus subsp. proximus is a wild aromatic herb that produces essential oils and terpenoids of pharmaceutical, antimicrobial and antioxidant properties. It is becoming endangered as a result of over collection for its multi-uses. Effect of different factors on axillary multiplication and growth from seed cultures in vitro were studied. Those included benzyl adenine concentrations, different sugar types, sugar alcohol types and concentrations and different silver nitrate concentrations. Among different concentrations of benzyl adenine used, 7 mg/l produced the highest number of shoots (27.0±4.5 shoots/explant), fresh weight and dry weight. Maltose, glucose and sucrose gave significantly higher shoot numbers and fresh weight than fructose, lactose and galactose. Addition of sorbitol in concentrations 2.25% in combination with 2.25% of sucrose significantly increased shoot numbers (35.5 ± 5.8 shoots/explant), while different concentrations of mannitol either did not affect or negatively affected biomass production. Silver nitrate at 2 mg/l improved shoots proliferation (33.4±3.7 shoot/explant), fresh weight and dry weights. For rooting, different concentrations of three auxin types used did not induce any rooting. Well develop strong roots were produced only on media containing 6% of glucose or sucrose. Humic acid significantly increased root growth. This study established an efficient, reproducible and rapid protocol for in vitro mass production of the species that can be used in folk medicine, in drug production, and also for ex-situ conservation.

Abstract: Olive cuttings are difficult to propagate. They root well using synthetic auxin, indole-3-butyric acid (IBA). To evaluate the rooting and viability of olive semi-hardwood cuttings of ‘Dakal’ and ‘Zard’ cultivars in response to application of growth retardant, paclobutrazol (PBZ), and interaction of IBA and PBZ, a greenhouse experiment was conducted in 2012. Cuttings were dipped for 30 minutes in PBZ (0, 1000, 2000, and 4000 mg.L -1 ) and for 50 seconds inIBA (2000 mg.L -1 ) solutions, respectively and then planted in a sandy bed of propagation under automatic mist system with 95% humidity and 20±5 o C base temperature. Results showed that cutting viability, percentages of rooted, callused and rooted plus callused cuttings and root growth parameters were higher in ‘Dakal’ cultivar than ‘Zard’ cultivar. The 2000 mg.L -1 PBZ treated cuttings had a higher cutting viability, rooting percentage, number of branches per cutting, shoot length, number of roots per cutting, root length and root fresh and dry weights than the control. It appears that the rooting of ‘Dakal’ cultivar can be substantially improved by the treatment of PBZ (included IBA).

TL;DR: In this article, the authors developed bridge maintenance prioritization criteria and ranked the bridges to be maintained based on the Analytic Hierarchy Process (AHP) method by using Bali Province as a case study.
Abstract: Transport agencies in developing countries are often faced by the need to maintain a lot of road projects but have limited budget. One important road infrastructure complement is bridge. The bridge is a vital infrastructure facilities for the continuing development of social and economic activities of the region. A serious problem in developing countries such as Indonesia is limited funds available for maintenance. In Bali Province, the priority of bridge maintenance program is prepared based only on the technical condition of the bridge. However, many aspects actually need to be considered. As limited funds available, the objective of this study is to develop bridge maintenance prioritization criteria and rank the bridges to be maintained based on the Analytic Hierarchy Process (AHP) method by using Bali Province as a case study. It was found that the stakeholders for bridge maintenance in Bali Province gave priority to road network system 1.34 times more than movement system, 1.56 times more than land use system and 2.49 times more than institutional system. The road network system was identified as the main factor considered in maintaining bridge in Bali Province. From 86 bridges considered in this study, it was found that 19 bridges were in the very high priority category. It was also found that the ranking of bridge maintenance priority based on the AHP method was very similar to the realized program.

This study examined a variable step-size block predictor-corrector method for solving first-order Ordinary Differential Equations (ODEs). Materials and Methods: The combination of Newton’s backward difference interpolation polynomial and numerical integration methods were applied and evaluated at some selected grid points to formulate the block predictor-corrector method. Nevertheless, this process advances to generate the PLTE of the block predictor-corrector method after establishing the order of the method. Results: The numerical results were shown to demonstrate the performance of the variable step-size block predictor-corrector method in solving first-order ODEs. The complete results were incurred with the aid of Mathematica 9 kernel for Microsoft windows (64bit). Conclusion: Numerical results showed that the variable-step-size block predictor-corrector method is more effective and perform better than existing methods in terms of the maximum errors at all tested tolerance levels as well as designing a suitable step size to control error.

TL;DR: In this paper, the authors have developed Equipment Criticality Analysis (ECA) protocols for carbon steel static mechanical equipment have been developed as criticality screening tools and the protocols were developed based upon DNV-RP-G101.
Abstract: Best practice in developing Inspection Plan for static mechanical equipment on offshore topside platform is by performing Risk-based inspection (RBI) analysis. However, there are hundreds or even thousands static mechanical equipment on offshore topside platform. Since detailed RBI analysis requires a lot of data and tedious calculation then it is necessary to do equipment criticality screening prior to perform detail RBI analysis as it is suggested in DNV-RP-G101. Equipment Criticality Analysis (ECA) protocols for carbon steel static mechanical equipment have been developed as criticality screening tools. The protocols were developed based upon DNV-RP-G101. ECA categorizes the static mechanical equipment into C1, C2, or C3 which refer to high, medium or low criticality equipment respectively. The C3 equipment will receive minimum surveillance with planned corrective maintenance while C2 and C1 equipment will require detail RBI analysis.

TL;DR: In this article, the authors used CR-39 plastic track detector strippable to measure radon concentrations to calculate the annual effective dose and lung cancer cases per year per million person for twenty different brand tobacco cigarette were collected from Iraqi market.
Abstract: Sealed can technique using CR-39 plastic track detector strippable has been used in order to measure radon concentrations to calculate the annual effective dose and lung cancer cases per year per million person for twenty different brand tobacco cigarette were collected from Iraqi market. Lung cancer is the leading cause of cancer-related deaths worldwide. Radon exposure is the second leading cause of lung cancer, following tobacco smoke. Radon is not only an independent risk factor; it also increases the risk of lung cancer in smokers. It has been observed that tobacco smoking increases the risks of radon-induced lung cancer. Radon and cigarette smoking have synergistic, multiplicative effect on lung cancer rates. People who inhale tobacco smoke are exposed to higher concentrations of radioactivity. Ever since studies on the relation of smoking to cancer, particularly the lung cancer has been established, there had been a great interest in studies concerned with the monitoring of the alpha radioactivity in tobacco. The results showed that the 222 Rn concentrations in cigarette tobacco samples ranged from (156.450 to 403.087) Bq/m 3 with an average 284.751 Bq/m 3 , while the radon induced lung cancer risks was found to vary from 71.047 to 183.049 with an av­erage value of 129.3107 per million person, and standard deviation 83.529 and 37.932, respectively. Excellent correlation has been observed between radon concentration and lung cancer cases per year per million person for different brand tobacco cigarettes.

TL;DR: Socio-demographic factors influenced the quality of life among Indonesian workers, as well as job characteristics (work status, work shift and work area condition), individual characteristics (education level) and lifestyles (sleep duration and exercise habit).
Abstract: Background and Objective: There are more than 7 million workers in the small and medium enterprises (SME) in Indonesia. The various occupational risks and environmental hazards threaten the health and well-being of these SME workers. It is important to promote occupational health and safety programs in order to improve quality of life (QOL). This study aimed to explore the socio-demographic profile and to examine the factors that impact the QOL among SME workers in Indonesia. Methodology: This study utilized a cross sectional study design. WHO quality of life (WHO-QOL) questionnaire was used to determine individuals perceptions of their position in life in the context of the culture and value systems in which they live and in relation to their goals, expectations, standards and concerns. Four domain scores include physical, psychological, environmental and social relationship. Sample for this study were 492 workers from 2 SME industries (food and textile). All of the industries were in registered in the Indonesia Ministry of Trade and Industry. Bivariate analysis was used by ordered logistic regression for quality of life in general with satisfaction of health as dependent variable and logistic regression for 4 domains as dependent variable. Results: The poor condition was found in social domain (36.58%, μ = 0.63, SD = 0.48), followed by psychological (32.32%, μ = 0.68, SD = 0.46), environmental (25.2%, μ = 0.75, SD = 0.43) and physical domain (17.47%, μ = 0.83, SD = 0.38). Quality of life among non-permanent employer was 0.5 times lower than permanent employees. Employees with higher educational level had better QOL (OR = 1.149 , CI = 1.063-1.242) in all domains. Employee with long duration of sleep had better QOL than those with short sleep duration. The SME workers who exercised regularly had 2 times better QOL (physical and social domain) and were more satisfied with their health than workers who did not exercise regularly. Conclusion: Socio-demographic factors influenced the quality of life among Indonesian workers, as well as job characteristics (work status, work shift and work area condition), individual characteristics (education level) and lifestyles (sleep duration and exercise habit).

TL;DR: In this paper, a simple, specific, precise, accurate, and sensitive method for separation and quantification of two flavonoids mainly apigenin (API) and luteolin (LUT) by reverse phase HPLC was developed and validated.
Abstract: A simple, specific, precise, accurate, and sensitive method for separation and quantification of two flavonoids mainly apigenin (API) and luteolin (LUT) by reverse phase high performance liquid chromatography (RP-HPLC) was developed and validated. Flavonoids present in the leaves of Clerodendrum serratum L. (C. serratum) were analyzed and quantified. Analysis was carried out on enable C18G column (250 mm × 4.6 mm i.d, 5 µm) as stationary phase, mobile phase consisting of methanol-acetonitrile-acetic acid-orthophosphoric acid-water (40:20:0.05:0.05:40) at a flow rate of 0.6 mL min -1 and detection wavelength at 352 nm. The proposed method was validated by ICH Harmonized Tripartite Guidelines, Validation of Analytical Procedures: Text and Methodology Q2 (R1). In this study, an excellent linearity was obtained with correlation coefficient (r 2 ) higher than 0.999. Besides, the chromatographic peaks also showed good resolution. Other validation parameters including precision, specificity, accuracy, and robustness demonstrated good reliability in the quantification of apigenin and luteolin. Thus the newly developed and validated method can be conveniently used for the quantification of API and LUT in leaves of C. serratum L. leaves and also be applied to standardization of multicomponent herbal remedies containing C. Serratum.

TL;DR: In this article, the root shear strength was analyzed using the direct shear test method to determine the root strength from the plotted graph. But the root growth was not investigated.
Abstract: Background: Carbonaceous shale is one of the common rock types in Malaysia. The most common types of landslides in Malaysia were happened on the cut slope before the construction of highway. Brachiaria ruziziensis and Colopogonium mucunoides were used as the mix vegetation to investigate the effect of chemical amendments on plant growth and root shear strength relationship. Objective: The objective of this study: (1) To investigate the effect of compound fertilizer nitrogen, phosphorus, potassium (NPK), NPK+Ground Magnesium Limestone (GML) (NGL), NPK+GML+foliar fertilizer (Vita-Grow™) (NGF) and control (Ctrl) and (2) To determine the soil shear strength, biomass and root growth. Materials and Methods: The soil samples were analyzed for pH, Total Nitrogen (TN), Soil Organic Carbon (SOC), available phosphorus, exchangeable Al, Ca, Mg and K and trace nutrients (Fe, Mn, Cu and Zn). Results: The carbonaceous shale was low in pH, total N, soil organic carbon, extractable P, basic cations (Ca, Mg and K) and micronutrients (Fe, Cu and Zn). Both P and Ca/Mg were low indicating inherent infertility and chemical constraints for root developments. The dry matter yield, root length and root weight of Brachiaria ruziziensis and Colopogonium mucunoides were increased significantly against NGF treatment. The increased of plant top and root dry weight treated with NGF were 26 and 38%, respectively, compared to the other treatments. The significant root shear strength relationship indicates that root enhanced shear strength by reducing the cohesion and increased the angle of internal friction component. The shear strength analysis from the direct shear test method is to determine the shear strength from the plotted graph. The shear strength analysis showed that NGF treatment was having high shear strength in 5.4, 10.9 and 16.3 and normal stress in 54, 109 and 163 kN m–2. Rapid vegetation growth observed within a 5 months period demonstrated that nutrient and lime application effectively ameliorated chemical constraints to plant growth. Conclusion: The plant mix species treated with NPK+GML+foliar fertilizer (NGF) indicated higher shear strength, dry matter yield and root densities in all layers.

TL;DR: In this paper, the DPPH (2, 2-diphenyl-1-picrylhydrazyl) free-radical scavenging constituent from the methanol extract of Polyalthia longifolia leaf using bioassay-guided fractionation was identified.
Abstract: Medicinal plants are sources of antioxidant compounds that have been reported to protect the human body from the adverse effects of free radicals. Therefore, the present study was intended to identify the DPPH (2, 2-diphenyl-1-picrylhydrazyl) free-radical scavenging constituent from the methanol extract of Polyalthia longifolia leaf using bioassay-guided fractionation. On the basis of DPPH radical scavenging assay-guided isolation, the leaf extract of P. longifolia was separated by employing a solvent partition of methanol leaf extract followed by Medium Pressure Liquid Chromatography (MPLC) and High-Performance Liquid Chromatography (HPLC) fractionation. The ethyl acetate fraction (EtOAc) revealed a strong antioxidant activity, compared to other fractions through in vitro DPPH radical-scavenging assay. The repeated fractionation of active EtOAc by MPLC separation and elution procedure yielded a sub-fraction EtOAc_F007 with strong antioxidant potential. The results indicated that the ethyl acetate sub-fraction EtOAc_F007 has noticeable effects on DPPH radical compared with other sub fractions. The sub fraction EtOAc_F007 was further purified using a preparative HPLC system. Subsequent Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS) analysis of the purified constituent from sub-fraction EtOAc-F007 led to the identification of rutin as the antioxidant agent in P. longifolia leaf extract. The results obtained suggested that extracts from P. longifolia leaf have potential use as a bioactive source of natural antioxidants by contributing valuable health effects.

TL;DR: In this paper, the effect of nitrogen fertilizer on the productivity of oil palm in small-scale plantations was investigated and the optimum N fertilizer rate was determined for a four-year-old oil palm (1 st mature oil palm).
Abstract: Fertilization is one of the methods to increase the productivity of oil palm in Indonesia, especially in smallholder plantations. The aim of this research were to study the effect of nitrogen (N) fertilizer and to determine the optimum N fertilizer rate for a four-year-old oil palm (1 st mature oil palm). This study was conducted at IPB-Cargill Teaching Farm of Oil Palm, Jonggol, Bogor, Indonesia from April 2016 to March 2017. This experiment used one factor of randomized complete block design that consisted of five treatment levels, three replications and five palm samples. The treatment levels were 0, 725, 1450, 2175 and 2900 g N palm -1 year -1 . Nitrogen fertilizer significantly affects the palm height, trunk girth, leaf area, leaf greenness, stomata density, leaf N content, bunch number, and productivity of fresh fruit bunches (FFB), but didn’t affect the frond length and average bunch weight on 1 st mature oil palm. The optimum N fertilizer rate was 1632 ± 207 g N palm -1 year -1 for four-year-old oil palm (1 st mature oil palm). Application of N fertilizer with application rate of 1632 g N palm -1 year -1 could increase the productivity by 35% compared to control (4.9 ton FFB ha -1 year -1 higher than control).

TL;DR: Authorship attribution of a style of writing is a method depend on analyzing texts in text mining, by choosing some attributes that show the author manner of writing.
Abstract: Authorship attribution of a style of writing is a method depend on analyzing texts in text mining, e.g., historical books and novels that famous authors wrote, attempted to measure the author's style, by choosing some attributes that show the author manner of writing. Assuming that these writers have a different way of writing that no other writer have; thus, authorship attribution is the essential of identifying the author of a given text [1].

TL;DR: In vitro antimicrobial activity screening carried out on the compounds against bacterial strains showed that the synthesized compounds have significant activities against the tested organisms, however, compound 5e did not inhibit the growth of Pseudomonas aeroginosa.
Abstract: The synthesis of various alkynylquinoline-5,8-diones is reported. The intermediate 6,7-dibromoquinoline-5,8-dione was obtained by nitrosation of 8-hydroxyquinoline, followed by reduction and subsequent bromination and oxidation. The coupling reaction of 6,7-dibromoquinoline-5,8-dione with various terminal alkynes via Palladium catalysis gave the alkynylquinoline-5,8-diones in good to excellent yields (50-85% ). The chemical structures of the products were confirmed using spectroscopic methods, which include UV/Visible spectrophotometer, Fourier Transform-Infrared (FT-IR) Spectroscopy, 1 H and 13 C-NMR Spectroscopy. In vitro antimicrobial activity screening carried out on the compounds against bacterial strains: Escherichia coli 1, Escherichia coli 12, Staphylococcus aureus, Klebsiella pneumonia and Pseudomonas aeroginosa, showed that the synthesized compounds have significant activities (MIC= 0.15-3.20), against the tested organisms. However, compound 5e did not inhibit the growth of Pseudomonas aeroginosa.
