Soil Moisture Measurement

Adaptation to climate change demands the optimal and sustainable water management in agriculture, with an inevitable focus on soil moisture conditions. In the current study we developed an ArcGIS 10.4. platform-based application (software) to model spatial and temporal changes in soil moisture in a soy field. Six SENTEK Drill & Drop soil moisture sensors were deployed in an experimental field of 4.3 hectares by the contribution of Elcom Ltd. Soil moisture measurement at each location were taken at six depths (5, 15, 25, 35, 45 and 55 cm) in 60-minute intervals. The model is capable to spatially interpolate monitored soil moisture using the technique. The time sequence change of soil moistures can be tracked by a Time Slider for both the 2D and 3D visualization. Soil moisture temporal changes can be visualized in either daily or hourly time intervals, and can be shown as a motion figure. Horizon average, maximum and minimum values of soil moisture data can be identified with the builtin tool of ArcGIS. Soil moisture spatial distribution can be obtained and plotted at any cross sections, whereas an alarm function has also been developed for tension values of 250, 1,000 and 1,500 kPa.

Abstract. Landslides occur frequently all over the world, causing at times considerable economic damage, injuries and even death. In order to improve hazard assessment, common landslide types of a given region need to be investigated in detail. While traditional techniques of subsurface investigation are expensive and only provide point information, geophysical methods are suitable tools for gathering 2D and 3D information on the subsurface quickly, reliably and cost-effectively. In this study, the suitability and limitations of 2D resistivity for the determination of landslide extent, structure and soil moisture conditions are presented. For this purpose, two identical profiles were taken during a two-month period. Significant differences in electrical resistivity (>1000 Ωm) due to varying soil moisture conditions were observed. Using various inversion parameters, it was possible to model two distinct subsurface images. Regrettably, the sliding plane could not be detected reliably, possibly due to the homogeniety of the landslide material and underlying bedrock.

The availability of datasets comprising of digitized images of human body cross sections (as well as images acquired with other modalities such as CT and MRI) along with the recent advances in fields like graphics, 3D visualization, virtual reality, 2D and 3D image processing and analysis (segmentation, registration, filtering, etc.) have given rise to a broad range of educational, diagnostic and treatment planning applications, such as virtual anatomy and digital atlases, virtual endoscopy, intervention planning etc. This chapter describes efforts towards the creation of the Virtual Dental Patient (VDP) i.e. a 3D face and oral cavity model constructed using human anatomical data that is accompanied by detailed teeth models obtained from digitized cross sections of extracted teeth. VDP can be animated and adapted to the characteristics of a specific patient. Numerous dentistry-related applications can be envisioned for the created VDP model. Here we focus on its use in a virtual tooth drilling system whose aim is to aid dentists, dental students and researchers in getting acquainted with the handling of drilling instruments and the skills and challenges associated with cavity preparation procedures in endodontic therapy. Virtual drilling can be performed within the VDP oral cavity, on 3D volumetric and surface models (meshes) of virtual teeth. The drilling procedure is controlled by the Phantom Desktop (Sensable Technologies Inc., Woburn, MA) force feedback haptic device. The application is a very promising educational and research tool that allows the user to practice in a realistic manner virtual tooth drilling for endodontic treatment cavity preparation and other related tasks.

Moisture Conditions

Food self-sufficiency is a government program that is currently being actively promoted, so that Indonesia can be independent in providing food by the end of 2019. Indonesia besides being a maritime country is also an agricultural country with fertile land with 2 seasons, namely the rainy season and the dry season. In the rainy season food plants usually do not need to be watered because they have enough rain water. Whereas in the dry season the plants must be watered regularly in accordance with soil moisture conditions. Farmers usually do not grow food in the dry season for fear that it will not grow well and crop failure. Dependence of farmers with the season causes farmer production to decline and becomes an obstacle in the success of the food self-sufficiency program. To overcome the constraints of the dry season and so that farmers can still plant crops in the dry season, we need an information and communication technology-based agricultural tool product in the form of a programmed chip mircrocontroller so that it can control watering plants automatically based on soil moisture that is detected using domestic soil moisture sensors . This tool will detect whether the soil where the planting is dry so that the tool can control watering automatically when the soil lacks the element of water. So farmers do not need to do watering manually. So that plants can continue to flourish even though it is the dry season. In addition to helping farmers this tool can also be installed on plantations, seedbed nurseries, urban parks, hotels, offices, and in homes that have parks or plants that need regular watering.   Keywords— Soil Moisture Sensor, Microcontroller, Arduino

2D Images

Periodontal disease is the most common oral disorder in the elderly population. Early detection of bony and soft tissue support changes is therefore crucial in relation to the prevention of tooth loss and/or the patient’s general health. Unfortunately, the current diagnostic tools for accurate assessment of this periodontal status have shown several limitations. Most image analysis tools are based on 2D images, while bone remodelling is a 3D process. At present, Cone Beam Computed Tomography (CBCT) has become a powerful diagnostic tool in dentistry. This chapter will bring an overview of 2D and 3D visualization methods of the periodontal tissues and their pathologic manifestations like infrabony craters and furcation involvements. The diagnostic use of 2D radiographic projections, image filtering and subtraction will be compared to the use of 3D cross-sections and the image analysis tools for 3D visualization and/or follow-up of bony changes.

Determine Effect

Improved stand establishment of direct-seeded crops has usually involved seed treatment and/or seed covers. Planters have been evaluated for seed/plant spacing uniformity, singulation, furrow openers, and presswheel design; however, effects of presswheels and seed coverers on plant establishment have not been widely investigated. Five experiments were conducted in a fine sandy loam soil to determine effect of presswheels and seed coverers on emergence of direct-seeded cabbage and mustard. Seed were planted with Stanhay 870 seeder equipped with one of four presswheels and seed coverers. Presswheels included smooth, mesh, concave split, and flat split types. Seed coverers included standard drag, light drag, paired knives, and no coverer. Soil moisture at planting ranged from 8% to 19% in the top 5 cm of bed. Differences in plant counts taken 2 weeks after planting were minimal with any presswheel or seed coverer. Visual observation indicated the seed furrow was more completely closed with the knife coverer in high soil moisture conditions. All tests received at least 14 mm of precipitation within 6 days from planting, which may account for lack of differences in plant emergence.
