A Sub-block Based Image Retrieval Using Modified Integrated Region Matching

This paper proposes a content based image retrieval (CBIR) system using the local colour and texture features of selected image sub-blocks and global colour and shape features of the image. The image sub-blocks are roughly identified by segmenting the image into partitions of different configuration, finding the edge density in each partition using edge thresholding followed by morphological dilation. The colour and texture features of the identified regions are computed from the histograms of the quantized HSV colour space and Gray Level Co- occurrence Matrix (GLCM) respectively. The colour and texture feature vectors is computed for each region. The shape features are computed from the Edge Histogram Descriptor (EHD). A modified Integrated Region Matching (IRM) algorithm is used for finding the minimum distance between the sub-blocks of the query and target image. Experimental results show that the proposed method provides better retrieving result than retrieval using some of the existing methods.Comment: 7 page

Viscous fingering in liquid crystals: Anisotropy and morphological transitions

We show that a minimal model for viscous fingering with a nematic liquid crystal in which anisotropy is considered to enter through two different viscosities in two perpendicular directions can be mapped to a two-fold anisotropy in the surface tension. We numerically integrate the dynamics of the resulting problem with the phase-field approach to find and characterize a transition between tip-splitting and side-branching as a function of both anisotropy and dimensionless surface tension. This anisotropy dependence could explain the experimentally observed (reentrant) transition as temperature and applied pressure are varied. Our observations are also consistent with previous experimental evidence in viscous fingering within an etched cell and simulations of solidification.Comment: 12 pages, 3 figures. Submitted to PR

A Deformable Model for Magnetic Vortex Pinning

A two-parameter analytical model of the magnetic vortex in a thin disk of soft magnetic material is constructed. The model is capable of describing the change in evolution of net vortex state magnetization and of core position when the vortex core interacts with a magnetic pinning site. The model employs a piecewise, physically continuous, magnetization distribution obtained by the merger of two extensively used one-parameter analytical models of the vortex state in a disk. Through comparison to numerical simulations of ideal disks with and without pinning sites, the model is found to accurately predict the magnetization, vortex position, hysteretic transitions, and 2-D displacement of the vortex in the presence of pinning sites. The model will be applicable to the quantitative determination of vortex pinning energies from measurements of magnetization.Comment: 27 pages, 7 figures, including supplementary information, ancillary files:3 supplementary movie

Response of rat hindlimb muscles to 12 hours recovery from tail-cast suspension

Previous work has shown a number of biochemical changes which accompany atrophy or reduced muscle growth in hindlimb of tail-casted, suspended rats. These results clearly show that altered muscle growth was due to changes in protein turnover. Accordingly, the rise in soleus tyrosine following unloading reflects the more negative protein balance. Other major changes we found included slower synthesis of glutamine as indicated by lower ratios of glutamine/glutamate and reduced levels of aspartate which coincide with slower aspartate and ammonia metabolism in vitro. In conjunction with the study of SL-3 rats, which were subjected to 12 h of post-flight gravity, a study of the effects of 12 h eight bearing on metabolism of 6-day unloaded hindlimb muscles was carried out

Responses of skeletal muscle to unloading, a review

Suspension models were used to study muscle response to reduced activity. During 6 days of tail casting, the soleus (SOL) atrophies while the extensor digitorum longus grows relatively normally. After discounting those changes in both muscles due primarily to increased secretion of adrenal hormones, the following conclusions regarding the specific responses of the SOL could be drawn: (1) Atrophy is probably due primarily to increased protein degradation; (2) Decreased synthesis of glutamine may result from reduced availability of ammonia due to diminished use of ATP; (3) Greater muscle glycogen seems to reflect an increased response to insulin of glucose uptake which leads to greater glucose metabolism; and (4) Faster catabolism of branched-chain amino acids can be attributed to enhanced flux through ketoacid dehydrogenase. Studies by others using tail casted suspended rats showed in the SOL: (1) a gradual switch from type 1 to type 2 fibers; (2) increased acid protease activity; and (3) altered muscle function and contractile duration. Using harness suspended rats, others showed in the SOL: (1) significant atrophy; (2) increased numbers of glucocorticoid receptors; and (3) no change in muscle fatigability

Pelaksanaan Pidana Mati Menurut Undang-undang Nomor 2/pnps/1964

Tujuan dilakukannya penelitian ini adalah untuk mengetahui bagaimana alasan-alasan yang diberikan oleh mereka yang pro pidana mati dan mereka yang kontra pidana mati dan bagaimana tata cara pelaksanaan pidana mati menurut Undang-Undang No. 2/PNPS/1964. Dengan menggunakan metode penelitian yuridis normative disimpulkan: 1. Alasan dari mereka yang pro pidana mati adalah karena adanya peningkatan kualitas dan kuantitas kejahatan dari waktu ke waktu, maka para penjahat yang makin mengganas perlu diberikan shock terapy (terapi kejutan), berupa pidana mati terutama bagi penjahat-penjahat tertentu yang memang tidak bisa lagi diharapkan untuk dapat berubah. Sedangkan mereka yang kontra pidana mati memberikan alasan bahwa pidana mati sifatnya final, sehingga sekali dijatuhkan tidak dapat diperbaiki lagi, walaupun ternyata terjadi kekliruan terhadap terpidana, juga pidana mati akan menutup kemungkinan bagi terpidana untuk memperbaiki kesalahannya di masa yang akan datang. 2. Berdasarkan Undang-Undang No. 2/PNPS/1964 maka tata cara pelaksanaan pidana mati di Indonesia dilakukan dengan ditembak sampai mati, oleh satu regu penembak, yang dilakukan disuatu tempat dalam daerah hukum pengadilan yang menjatuhkan putusan tingkat pertama, terkecuali ditentukan lain oleh Menteri Kehakiman Dan Hak Asasi Manusia, yang pelaksanaannya dihadiri oleh komisariat daerah (Kapolres) atau perwira yang ditunjuknya bersama dengan Jaksa Tinggi/Jaksa yang bertanggung jawab
