Abstract:
Gravity is a phenomenon that has been part of the universe since its creation. This phenomenon is when an object pulls everything around it toward the center of the object. Gravity itself was discovered by Sir Isaac Newton in the 17th century. Humans think that there is no such thing as anti-gravity. This research aims to prove that the value of a planet's gravity can change under certain conditions. In addition, this research also aims to prove that humans can create something that causes all objects in a particular area to have a value close to anti-gravity. In short, 3 influences can change

Abstract:
Inter-seasonal and geodynamics-related gravity changes are important geoscientific signals that are extractable from gravimeter observations after removing background information as local hydrology gravity effect. With two superconducting gravimeters (SGs: OSG-053 and iGrav-007) located in different tectonic units, continuous global navigation satellite system data and absolute gravity observations, Wuhan, China, is an ideal location for investigating the effects of gravity resulting from significant local hydrology mass variations.

Abstract:
Time-lapse gravity is a technique sensitive to subsurface change in mass and in mass distribution. We attempted to devise a method to predict gravity effects caused by redistribution of subsurface mass induced by reservoir compaction. First, displacements and strains due to compaction were modeled using a geomechanical model. Then, 4D gravity effects were derived from the displacements and the volumetric strains computed in and around the reservoir. A sensitivity study was carried out for geomechanical parameters, such as Poisson’s ratio, as well as for geometrical parameters, such as reservoi

Gravity changes (corrected for subsidence) of up to -1 000 (±300) μGal have occurred in the [Formula: see text] area of the production bore field at Wairakei, and smaller decreases extend over a [Formula: see text] surrounding area. The largest part of these decreases occurred during the 1960s; since then the net gravity change for the whole field has been zero, indicating mass flow equilibrium. The principal causes of gravity change have been deep liquid pressure drawdown which resulted in formation of a steam zone, subsequent saturation changes in the steam zone, liquid temperature decline,

Analysis of gravity changes to altitude changes from gravity measurements at Merapi Volcano and Kelud Volcano was carried out to determine the characteristics of the two mountains based on the gravity method.

Repeated gravity surveys will be useful for studying deformation in volcanoes and providing information about changes in subsurface mass.

National and International research groups from Indonesia, France, Netherlands, Japan, USA and Germany are working on Merapi.

Abstract:
Leakage properties of isotropic and anisotropic filters used to recover mass changes from space gravity observations are studied. These are done through the use of gravity induced by simulated mass changes within a closed-loop validation procedure. Results show that the use of filter techniques can introduce significant errors introducing distortions between recovered and simulated mass. Previously not well known, the study revealed that leakage is dependent on the geographic location if the mass change considered.

Understanding how global ice volume on the Earth has changed is of significant importance to improving our understanding of the climate system. Fortunately, the geographically unique perturbations in sea level that result from rapid changes in the mass of, otherwise difficult to measure, land-ice reservoirs can be used to infer the sources and magnitude of melt water. We explore the history of land-ice mass changes through the effect that these mass fluxes have had on both global and regional gravity and sea-level fields.<br>Earth and Planetary Sciences

Abstract:
In order for an aircraft to remain in stable flight, the center of gravity (CG) of an aircraft must be located in front of the center of lift (CL). As the center of gravity moves rearward, pitch stability decreases and the sensitivity to control input increases. This increase in sensitivity is known as pitch gain variance. Minimizing the pitch gain variance results in an aircraft with consistent handling characteristics across a broad range of center of gravity locations.

Abstract:
In astrophysics, a significant role is played by observations. During astronomy classes in the absence of surveillance tools interactive programmes such as an interactive programme for space objects simulation can be used as Universe Sandbox2. The aim of this work is to implement interactive programmes for effective astronomy teaching, understanding material and increasing cognitive interest. We observe the evolution of stars while using Universe Sandbox2 during the study of the topic “Evolution of stars”. Using this programme students have an opportunity to get acquainted with the existence o

Abstract:
MAGIC is the joint NASA/ESA constellation concept based on NASA’s Mass Change Designated Observable (MCDO) and ESA’s Next Generation Gravity Missions (NGGM) studies. The main objective of MAGIC is to extend the mass transport time series of previous gravity missions such as GRACE and GRACE-FO with significantly enhanced accuracy, spatial and temporal resolutions and to demonstrate the operational capabilities of MAGIC with the goal of answering global user community needs to the greatest possible extent. This document defines unambiguous and traceable requirements for preparing and developing

Abstract:
Original objectives: The basic goal of the present project was to increase our understanding of the cellular mechanisms operating during the gravitropic response of cut flowers, for solving their bending problem without affecting flower quality. Thus, several elements operating at the 3 levels o the gravity-induced signal transduction pathway, were proposed to be examined in snapdragon stems according to the following research goals: 1) Signaling: characterize the signal transduction pathway leading to the gravitropic response, regarding the involvement of [Ca2+]cyt as a mediator of IAA moveme

Abstract:
The Next Generation Gravity Mission (NGGM) is a Mission of Opportunity as part of ESA’s FutureEO programme. NGGM will extend and improve time series of satellite gravity missions by providing enhanced spatial and temporal resolution time-varying gravity field measurements with improved performance and and latency. The mission addresses international user needs as expressed by IUGG and GCOS and demonstrates operational capabilities relevant for Copernicus. The NGGM Mission Requirement Document (MRD) defines unambiguous requirements for NGGM, traceable to the joint ESA/NASA MAss Change and Geosc
