The transmit array of multi-overlapped-transmit-subarray configured bistatic multiple-input multiple-output (MOTS MIMO) radar is partitioned into a number of overlapped subarrays, which is different from the traditional bistatic MIMO radar. In this paper, a new unitary ESPRIT scheme for joint estimation of the direction of departure (DOD) and the direction of arrival (DOA) for MOTS MIMO radar i...

the group size and behavior of goitered gazelle was studied over the year 2001 in kalmand-bahadoran protected area. gazelle groups showed no stable organization in kalmand protected area. in spring season, group size was smaller than other seasons and the largest groups were seen in winter. number of solitary gazelles increased during the mating season. adult males were territorial in mating se...

A scheme is developed which shows how one would, given a light-front Hamiltonian for QCD, extract the QQ potential, i.e. the quantity which corresponds to the potential between two infinitely heavy quarks in a rest frame, from a light-front calculation. The resulting potential will in general depend on the direction along which the infinitely heavy sources are separated and thus provides a dire...

We present a new finite element scheme for solving the Navier-Stokes equations that exactly conserves both energy ( ∫ Ω u) and helicity ( ∫ Ω u · (∇× u)) in the absence of viscosity and external force. We prove [email protected], http://www.math.pitt.edu/∼ler6 Partially supported by NSF Grant DMS 0508260 and 0207627 1 stability, exact conservation, and convergence for the scheme. Energy and helicit...

a palatal defect may result from surgical resection, and its consequences could include difficulty in speech and nasal regurgitation of food and liquids. an obturator combined to speech aid prosthesis can improve nasal emission during speech,  and  assist  in  preventing  nasal  regurgitation  of  food.  this  article presents a clinical report of the reconstruction of palatopharyngeal function...

to evaluate fertility status and mating type distribution of cryphonectria parasitica, causal agent of chestnut blight in guilan province, four sites in two main growing regions of: shaft (visrud, taleghan and babarekab), and rezvanshahr (doran) were investigated. during the study, fifty four isolates of c. parasitica were examined. c. parasitica isolates were crossed with each of the two matin...

A promising approach to reducing disk energy consumption is to use multi-speed disks with lower rotational speeds, and allowing disks to run slowly when workloads are light can reduce their large contribution to the power used by video servers. We propose an SSD cache management scheme for video servers which use multi-speed disks. We formulate an integer linear problem (ILP) that determines vi...

We present a new quadrotor geometric control scheme that is capable of tracking highly aggressive trajectories. Our controller uses the logarithmic map SO(3) to express rotational error in Lie algebra, and we show it globally attractive without requiring complicated hybrid switching scheme. performance our against trajectories simulation experiments. Additionally, an adaptation this allows us i...

Visual cryptography scheme is the concept of encrypting a secret image into n(more than one) shares. Rotation Visual Cryptography scheme (RVCS) allows four secret images to be encrypted into two shares. Using Human Visual System, again the four secret images can be easily recovered by placing the two shares on top of each other with different angles. In this paper proposes a Rotation Visual Cry...

If mating with an inferior male has high fitness costs, females may try to avoid mating with these males. Alternatively, females may accept an inferior male to ensure they have obtained at least one mate, and/or to avoid the costs of resisting these males. We hypothesized that females compensate for mating with an inferior male by remating. We tested this hypothesis by measuring remating propen...
