A new type of range searching problem, called the partial enclosure range searching problem, is introduced in this paper. Given a set of geometric objects S and a query region Q, our goal is to identify those objects in S which intersect the query region Q by at least a fixed proportion of their original size. Two variations of this problem are studied. In the first variation the objects in S a...

Organization of living environment is possible through a clear definition of private and public arenas and determinationof a spatial hierarchy. Such defined arenas increase the sense of belonging to the environment which personalizesresidential environments. Enclosure is among the quantities that play a significant role in defining the spaces. In fact,enclosure is the factor that defines a spac...

The design of future large optical telescopes must take into account the wind-induced vibration of the telescope structure that is caused by large-scale flow structures and turbulence inside the telescope enclosure when the aperture in the enclosure dome is open. However, estimating the resulting degradation in image quality is difficult due to our relatively poor understanding of the flow insi...

Finite Difference Time Domain (FDTD) is applied to study the characteristics of electromagnetic interference for power plane-battery management system (PP-BMS) enclosure, for modeling the coupling of an incident electromagnetic pulse (EMP) with a conducting wire through a BMS enclosure and aperture on it. Simulation and analysis are done by radius of the wires, incidence angles of EMP in the co...

A simple technique for the measurement of the shielding efficiency of a symmetric enclosure is presented. It allows measurements in the symmetry plane of the enclosure without the need of introducing cables which could interfere with the results. Comparisons with simulation results are shown. Limits of the concept of shielding efficiency of enclosures at high frequencies are also briefly discus...

The negative impact of anthropogenic noise on marine animals is receiving increasing attention. In order to study the effect of motorboat noise on foraging behaviour in fish, we chose 2 species with different hearing abilities. The roach Rutilus rutilus has a better developed sense of hearing than the Eurasian perch Perca fluviatilis. The study took place in an inlet of the Bothnian Sea where b...

Robot Navigation in unknown and very cluttered environments constitutes one of the key challenges in unmanned ground vehicle (UGV) applications. Navigational limit cycles can occur when navigating (UGVs) using behavior-based or other reactive algorithms. Limit cycles occur when the robot is navigating towards the goal but enters an enclosure that has its opening in a direction opposite to the g...

INCE Kerridge's incisive intervention into the field of agrarian history in his article of 1955 regarding the enclosure movement in the Tudor and early-Stuart period, anyone who ventures there must preface their remarks by acknowledgement of the force of Kerridge's argument. 1 As a result, little confidence may be retained in the basis of analysis of enclosure in that period the statistics whic...

The natural convection heat transfer of horizontal rectangle enclosures with different aspect ratios (A = 2:1 and A = 4:1) filled with Ag-Ga nanofluid (different nanoparticle volume fractions φ = 0.01, φ = 0.03, φ = 0.05 and radiuses r = 20 nm, r = 40 nm, r = 80 nm) at different Rayleigh numbers (Ra = 1 × 103 and Ra = 1 × 105) is investigated by a two-phase lattice Boltzmann model. It is found ...

Livestock grazing is one of the most important kinds of land usage that has a high potential to decrease or increase carbon storage in rangeland ecosystem. This research was investigated the effects of enclosure on soil carbon storage in a rangeland with dominant plants of Artemisia aucheri. Hence, two rangelands of enclosure (Shahtappeh-Chah Mahmood) and no enclosure (Chiro) were chosen in Sem...
