Approximation Method for Estimating Search Times for On-Street Parking

We propose an approximation method for estimating the probability [Formula: see text] of searching for on-street parking longer than time [Formula: see text] from the start of a parking search near a given destination [Formula: see text] based on high-resolution maps of parking demand and supply in a city. We verify the method by comparing its outcomes to the estimates obtained with an agent-based simulation model of on-street parking search. As a practical example, we construct maps of cruising time for the Israeli city of Bat Yam and demonstrate that, despite the low overall demand-to-supply ratio of 0.65, excessive demand in the city center results in a significant share of parking searches that last longer than 5 or even 10 minutes. We discuss the application of the proposed approach for urban planning.

Portolankarten – Aufnahme und Abbildung

Maps are flat images of the earth‘s surface. The basis and prerequisite for their production is the relative spatial definition of the map content on the earth‘s surface, and this is usually done in the context of surveying recording processes. The particular accuracy of the portolan charts, which have passed on since the thirteenth century, suggests that these were also created on the basis of specific measurements, although details of their creation have not yet been clarified. Questions about the data base and especially about the projection of the maps have been the subject of scientific research for over 100 years (Kretschmer 1909; Campbell 2021). Here, for the first time, a method is presented that makes it possible to construct maps of the Mediterranean with simple aids (compasses and ruler) in such a way that they correspond to the accuracy and other properties of the portolan charts. A map projection is used for which there are no mapping equations, but at most a mapping description. As a surveying basis for the mapping, distances are used that have been determined with a high degree of probability since ancient times. Triangles are constructed from these lines and transferred directly to the plane without any reduction in the image. The result is a geometrically unambiguous field of support points of known ports. The missing coastal structures can be supplemented after the construction of the field of support points on the basis of traditional coastal descriptions (Portolani/Periploi).

Analyzing the Diurnal Cycle by Bayesian Interpolation on a Sphere for Mapping GNSS Radio Occultation Data

Bayesian interpolation has previously been proposed as a strategy to construct maps of radio occultation (RO) data, but that proposition did not consider the diurnal dimension of RO data. In this work, the basis functions of Bayesian interpolation are extended into the domain of the diurnal cycle, thus enabling monthly mapping of radio occultation data in synoptic time and analysis of the atmospheric tides. The basis functions are spherical harmonics multiplied by sinusoids in the diurnal cycle up to arbitrary spherical harmonic degree and diurnal cycle harmonic. Bayesian interpolation requires a regularizer to impose smoothness on the fits it produces, thereby preventing the overfitting of data. In this work, a formulation for the regularizer is proposed and the most probable values of the parameters of the regularizer determined. Special care is required when obvious gaps in the sampling of the diurnal cycle are known to occur in order to prevent the false detection of statistically significant high-degree harmonics of the diurnal cycle in the atmosphere. Finally, this work probes the ability of Bayesian interpolation to generate a valid uncertainty analysis of the fit. The postfit residuals of Bayesian interpolation are dominated not by measurement noise but by unresolved variability in the atmosphere, which is statistically nonuniform across the globe, thus violating the central assumption of Bayesian interpolation. The problem is ameliorated by constructing maps of RO data using Bayesian interpolation that partially resolve the temporal variability of the atmosphere, constructing maps for approximately every 3 days of RO data.

Developing an assessment framework of multidimensional scientific competencies

The study aimed to develop and validate an assessment framework of multidimensional scientific competencies for seventh-grade students in the northeastern region of Thailand. A total of 289 samples with three different scientific competency levels were randomly selected to participate as testtakers. The design-based research encompassing four phases of the construct modelling approach, namely construct maps, item design, outcome space, and Wright map. Multidimensional Random Coefficient Multinomial Logit model was employed to examine the quality of the created assessment framework of multidimensional scientific competencies. The results showed that scientific competence is comprised of three dimensions, namely explain phenomena scientifically, evaluate and design scientific inquiry, and interpret data and evidence scientifically. Each dimension can be further categorized into four levels. The assessment framework consists of 16 items. The results revealed that there is validity evidence regarding internal structure based on the comparison of the model fit and Wright map. Moreover, results also indicated that the reliability evidence and item fit are compliance with the quality of the assessment framework as revealed in the analysis of standard error of measurement and infit and outfit of the items. It can be concluded that the assessment framework is currently prevalent to assess the scientific competencies of seventh-grade students.

A difficult problem is to make a vision-based robot navigate properly to the target by avoiding the obstacles. Path information is very essential for successful navigation of the robot. The main purpose of this paper is to present an approach for mobile robots to generate path and construct maps. This work is focused on providing the path information of an environment using a single 2-D camera. Whenever robot identifies the human in the corridor, it generates the information of the path information and constructs the map is achieved based on the human moment and the human position. On the robot the camera is mounted which acquires images in real time. Oath information is generated for mobile robot using acquired real time images and processing real time images

Review on medicinal importance of Vigna genus

Globally, there are more than 500,000 plant species (green scum, duckweed, lichens, liverworts, fungi, ferns, conifers, mosses and flowering plants etc.) that maintain earth’s environmental equilibrium, ecosystem stability and also possess vast endemic, aesthetic and cultural importance, provide medicine, food, fuel, shelter and clothing. Plants are used as therapeutic agents to improve health by a large part of population. Several clinical facts suggest that plant derived foods hold various potential health benefits and well known as neutraceuticals. These are the products that are used as food or as a part of food (foodstuffs), able to cure and prevent diseases in addition to their basic nutritional value. More than 200,000 chemical compounds are synthesized by plants and no doubt, also possess medicinal importance. Worldwide, about 70% plant based preparations are used as traditional medicines and also facilitate the base for 50 percent of prescription and/or over the counter drugs used in the Western-type practice of medicine. For underdeveloped and developing countries, it is a need to provide safe, efficient and cheap medications. In various part of India medicinal plants are widely distributed and always have increasing demand due to their medicinal properties. The present review is focused on the genus Vigna which is widely cultivated and used as neutraceuticals. They grow in varied climatic zones, in high temperatures, low rainfall and poor soils with low input in form of fertiliser and irrigation that make them valuable crop plants. As Vigna is an important genus that fulfils the food demand, useful in cosmetics and medicines, there is scope to enhance its productivity via resource conservation, optimum use of rainwater, bridging the yield gaps and innovations in technology transfer and up scaling. One of the important steps to find out a way to increase the production is the detection and analysis of naturally occurring DNA sequence variation by using DNA markers or molecular markers as these markers are indispensable tool that construct maps of genetic linkage and mark the agronomically important traits.

Geochemistry and catagenetic transformation of kerogen from the bazhenov horizon

A representative suite of 276 samples was used to study the isotopic and element geochemistry of kerogens from the Bazhenov horizon (Bazhenov Formation and its time equivalents) of the West Siberian sedimentary basin and to construct maps reflecting changes in the elemental composition of kerogen. The elemental composition of kerogen was used to determine the types of organic matter (H and C contents), the initial components of the living matter, the sources of kerogen (H and N contents), diagenetic history of organic matter (S content), the level of catagenetic transformation (C and O contents). Kerogen from the central, western and southern regions of the West Siberian basin toward the boundary of the Bazhenov horizon pinch-out shows strong enrichment in hydrogen (up to 8–9%) and 12С (δ13С‰ from -35 to -29), suggesting its derivation from the polymer lipids of aquatic origin. Kerogen from the Bazhenov horizon (catagenetic grade MC1) in the northeast of the basin contains much lower hydrogen concentrations (2–4%). A map of organic matter types in the Bazhenov horizon was constructed.

Distribution of mineral phases in the Eocene Green River Formation, Piceance Basin, Colorado—Implications for the evolution of Lake Uinta

The mineralogy of the Eocene Green River Formation in the Piceance Basin, Colorado, has been the subject of numerous studies since the 1920s. Most previous work has focused on the resource potential of these lacustrine mudrocks, which in addition to substantial oil shale potential (in-place resources of 353 billion barrels of synthetic crude oil for rocks yielding at least 25 gallons per ton, GPT), includes nahcolite, a currently utilized soda ash resource, and dawsonite, a potential alternative source of aluminum. Another reason to study the mineralogy in this system is that the geographic and stratigraphic distribution of various authigenic minerals may provide insights into the geochemistry and depositional environment of the long-lived Eocene Lake Uinta. In this study, legacy non-quantitative (presence/absence) X-ray diffraction (XRD) data recently published by the U.S. Geological Survey (USGS) for more than 9,000 samples collected from 30 coreholes in the Green River Formation, Piceance Basin were examined. These data were used to better define the stratigraphic and paleogeographic extent of a set of indicator minerals (illite, analcime, albite, dawsonite, and nahcolite) within the Piceance Basin lacustrine strata. This set of minerals was selected based on observations from previous work and variability in their occurrence and co-occurrence within the Piceance Basin. The USGS database has been used to (1) construct maps showing geographic variations in mineral occurrences for 14 stratigraphically defined rich and lean oil shale zones; (2) assess co-occurrences of indicator minerals; and (3) compare occurrence results with quantitative XRD datasets collected on Piceance Basin oil shales. Occurrences of many authigenic minerals (analcime, dawsonite, and nahcolite) varied in the lacustrine strata near and around the depocenter, but others, like quartz, dolomite, and feldspar (potassium + undifferentiated), were widely and consistently present (>90% of samples) across the basin. Shifts in the distribution of indicator mineral occurrences generally coincide with changes identified in previous lake history descriptions and indicate that the water chemistry of Lake Uinta varied significantly going from near-shore to the depocenter and through time.

A NIKA view of two star-forming infrared dark clouds: Dust emissivity variations and mass concentration

Context. The thermal emission of dust grains is a powerful tool for probing cold, dense regions of molecular gas in the interstellar medium, and so constraining dust properties is key to obtaining accurate measurements of dust mass and temperature. Aims. By placing constraints on the dust emissivity spectral index, β, towards two star-forming infrared dark clouds – SDC18.888–0.476 and SDC24.489–0.689 – we aim to evaluate the role of mass concentration in the associated star-formation activity. Methods. We exploited the simultaneous 1.2 and 2.0 mm imaging capability of the NIKA camera on the IRAM 30 m telescope to construct maps of β for both clouds, and by incorporating Herschel observations, we created H2 column density maps with 13′′ angular resolution. Results. While we find no significant systematic radial variations around the most massive clumps in either cloud on ≳0.1 pc scales, their mean β values are significantly different, with β̅ = 2.07 ± 0.09 (random) ± 0.25 (systematic) for SDC18.888–0.476 and β̅ = 1.71 ± 0.09 (random) ± 0.25 (systematic) for SDC24.489–0.689. These differences could be a consequence of the very different environments in which both clouds lie, and we suggest that the proximity of SDC18.888–0.476 to the W39 H II region may raise β on scales of ~1 pc. We also find that the mass in SDC24.489–0.689 is more centrally concentrated and circularly symmetric than in SDC18.888–0.476, and is consistent with a scenario in which spherical globally-collapsing clouds concentrate a higher fraction of their mass into a single core than elongated clouds that will more easily fragment, distributing their mass into many cores. Conclusions. We demonstrate that β variations towards interstellar clouds can be robustly constrained with high signal-to-noise ratio (S/N) NIKA observations, providing more accurate estimates of their masses. The methods presented here will be applied to the Galactic Star Formation with NIKA2 (GASTON) guaranteed time large programme, extending our analysis to a statistically significant sample of star-forming clouds.
