Off-Shell Formulation of Supergravity on Orbifold

An off-shell formulation is given for the ``supersymmetry in singular spaces'' which has recently been developed in an on-shell formalism by Bergshoeff, Kallosh and Van Proeyen using supersymmetry singlet `coupling constant' field and 4-form multiplier field in five-dimensional space-time. We present this formulation for a general supergravity-Yang-Mills-hypermultiplet coupled system compactified on an orbifold $S^1/Z_2$. Relations between the bulk cosmological constant and brane tensions of the boundary planes are discussed.Comment: 23 pages, no figures, LaTeX, PTPTeX styl

Effective Use of Dilated Convolutions for Segmenting Small Object Instances in Remote Sensing Imagery

Thanks to recent advances in CNNs, solid improvements have been made in semantic segmentation of high resolution remote sensing imagery. However, most of the previous works have not fully taken into account the specific difficulties that exist in remote sensing tasks. One of such difficulties is that objects are small and crowded in remote sensing imagery. To tackle with this challenging task we have proposed a novel architecture called local feature extraction (LFE) module attached on top of dilated front-end module. The LFE module is based on our findings that aggressively increasing dilation factors fails to aggregate local features due to sparsity of the kernel, and detrimental to small objects. The proposed LFE module solves this problem by aggregating local features with decreasing dilation factor. We tested our network on three remote sensing datasets and acquired remarkably good results for all datasets especially for small objects

Investigation on the flow field in nano-separator considering a fluid-structure interaction

Recently, in various areas, equipments to separate and classify nano-size particles are required. However, the production and collection of nano-particles are very difficult and cost consuming with current technologies. Therefore, we have been investigating a new solid-liquid separator in order to efficiency separate nano-particles from liquid. This separator enables us to separate and classify nano-size particles by using centrifugal force and differences in specific gravity. However, the separation phenomena of particles from liquid have not been clarified yet. Therefore, the design of the separator depends only on the emprical trial and error. Hence, a numerical simulation is expected to be a useful analysis and design tool for determining the optimum shape and dimensions. A rotating screw in the separator is deformed by centrifugal force and flow drag, and thus the screw deformation may change the separation performance. Therefore, it is required to consider the screw deformation for the optimum design. In the present study, we computed the fluid-structure interaction between the screw and liquid with MPS method. The local flow field in the simplified separator that consists of a 2D rotating flat plate and a cylinder is computed to investigate the effect of the screw deformation on the flow field in the separator. It is confirmed that the flow field in the solid-liquid separator is changed by the screw deformation

Superconformal Tensor Calculus in Five Dimensions

We present a full superconformal tensor calculus in five spacetime dimensions in which the Weyl multiplet has 32 Bose plus 32 Fermi degrees of freedom. It is derived by the dimensional reduction from the 6D superconformal tensor calculus. We present two types of 32+32 Weyl multiplets, vector multiplet, linear multiplet, hypermultiplet and nonlinear multiplet. Their superconformal transformation laws and the embedding and invariant action formulas are given.Comment: 31 pages, LaTeX, PTPTeX style, no figures, typos correcte
