We study spacecraft motion near a binary asteroid by means of theoretical and computational tools from geometric mechanics and dynamical systems. We model the system assuming that one of the asteroids is a rigid body (ellipsoid) and the other a sphere. In particular, we are interested in finding periodic and quasi-periodic orbits for the spacecraft near the asteroid pair that are suitable for o...

We investigate the spectrum of elementary particles and fields arising from the superposition of string configurations weighted according to their entropy in the string phase space. We find that this superposition describes a universe with a physical content phenomenologically compatible with the experimental observations and measurements. Masses and couplings are determined as functions of the...

Observations in the region of the Pribilof Islands and Canyon (PIC) reveal a clockwise circulation around the group of islands and around each of the two largest islands, St. Paul and St. George. Six current meters deployed around St. Paul Island revealed a steady clockwise flow around the island, which was strongest south of the island and weakest to the east. We use a high-resolution tidal mo...

Domain-specific Internet of Things (IoT) applications are becoming more and more popular. They process data coming from sensor measurements. Adding semantic annotations to the sensory observations and measurements can allow to reason on data via logical rules. Stemming from Linked Open Data and Linked Open Vocabularies, we have designed sensor-based Linked Open Rules (S-LOR). S-LOR allows explo...

Succinonitrile dendrites, growing under steady-state conditions, are subjected to a rapid change in pressure. This leads to a rapid change in thermal driving force from the corresponding change in equilibrium melting temperature due to the Clapeyron effect, and a change in the far-field temperature due to adiabatic temperature changes in the bulk liquid and solid. This allows us to observe a de...

Tax incentives are one of the government's responses to impact COVID-19 pandemic on businesses, and businesses affected by this is MSMEs. Therefore, study aims determine effect final income tax borne government following PMK No.44/2020, in form ease calculating payable, reporting payable compliance with realization letter No.44/2020. This used primary data distributing questionnaires MSMEs Dram...

Observational data (i.e., data that records observations and measurements) plays a key role in many scientific disciplines. Observational data, however, are typically structured and described in ad hoc ways, making its discovery and integration diÆcult. The wide range of data collected, the variety of ways the data are used, and the needs of existing analysis applications make it impractical to...

Hydrocarbon exploration has been underway in the north of West Siberia for several decades. Giant gas fields on the Yamal Peninsula are expected to begin feeding the Nord Stream pipeline to Western Europe in late 2012. Employing a variety of highto very high-resolution satellite-based sensors, we have followed the establishment and spread of Bovanenkovo, the biggest and first field to be develo...
