Image databases: Problems and perspectives

With the increasing number of computer graphics, image processing, and pattern recognition applications, economical storage, efficient representation and manipulation, and powerful and flexible query languages for retrieval of image data are of paramount importance. These and related issues pertinent to image data bases are examined

Single Phase Inverter Topology with A Voltages Topology Chain-Connected Energy Store

MIC focus mainly on single-phase power systems (e.g., 240V), and are often limited to collecting power activities. In this way, the converter must transmit the normal power and part of the power switch time by multiplying the flow line, while it will always be forced into the PV module. This indicates the movement of energy as opposed to the unit time of the PV range, and the location hidden between the curves indicating the ground strength required for inverter storage. To display this exchange by switching, a three-port frame can be used. The use of energy storage in a double line that doubles the power difference means separating existing plans. This introduces another Geography that puts a barrier to keeping the size in alignment associated with the square of the line connector. This facility provides free electrical volume control, accurate exchange of all semiconductor devices, and dual finished network work

Questioning heteronormative higher education spaces: experiences of lesbian women at a South African university

This paper narrows the gaze on sexual orientation and focuses on a group of university-going women who self-identify as lesbian. The paper works from the understanding that there is an intersectional prism through which women’s experiences need to be understood.  Thus, working within an intersectional paradigm and narrative analysis, the paper attempts to situate the experiences and shared stories of a core sample community of a small group of university women against a human rights discourse and what is understood by the women as their entitlement to full sexual citizenship within the institutional spaces of the university. Findings reveal that the women feel that the imperatives of university transformation hold little meaning in terms of their personal sexual orientation. Findings also show that in the perceived absence of institutional support, the women draw on nodal ties and social capital embedded in student social groups where kinship and acceptance is offered

On Synthesis of (k,K) Circuits.

circuit is one which can be decomposed into nonintersecting blocks of gates where each block has no more than K external inputs, such that the graph formed by letting each block be a node and inserting edges between blocks if they share a signal line, is a partial k-tree. (k;K) circuits are special in that they have been shown to be testable in time polynomial in the number of gates in the circuit, and are useful if the constants k and K are small. We demonstrate a procedure to synthesise (k;K) circuits from a special class of Boolean expressions

A cost variation analysis study of various bisphosphonates preparations available in the Indian market

Background: Osteoporosis is a chronic disease leading to weakened and porous bones which increases the risk of fractures. It is a treatable condition using drugs like bisphosphonates. There is wide variation in the cost among various brands of bisphosphonates in the Indian market, so the objective of the study was to analyse cost of different brands of bisphosphonates.Methods: Cost of both oral and injectable bisphosphonates in the same strength and dosage forms was obtained from CIMS India (January-April 2019). For oral form of the drug, price was calculated per 10 tablets, for injectable form the price per ampoule or vial was calculated and cost ratio, percentage of cost variation was calculated.Results: 15 different formulations of bisphosphonates were analyzed and it was found that cost ratio is found to be highest with 60 mg of pamidronate injection and lowest with 10 mg alendronate tablet, also pamidronate 60 mg injection has highest percentage of cost variation (9632%) and lowest cost variation is seen with 10 mg alendronate (35%). Cost ratio of 11 formulations was found to be very high which was >2 while percentage of cost variation of 11 formulations was found to be more 100.Conclusions: This study concludes that there is wide variation in cost of various brands of bisphosphonates in India. The huge price variation creates unnecessary burden leading on the patients resulting in noncompliance which increases the risk of morbidity and mortality. Therefore, there is an urgent need to regulate the cost of various formulations of bisphosphonates which will reduce the financial burden on the patients

A study to evaluate the skeletal muscle relaxant property of Pregabalin and Gabapentin in albino rats

Background: Skeletal muscle relaxants are the drugs which reduce unwanted spasm without interfering with consciousness and voluntary movements. The centrally acting muscle relaxants like Diazepam, is known to be GABA mimetics and other antiepileptics like Gabapentin and Pregabalin also act through the release of GABA. This study is done to investigate skeletal muscle relaxant property of these drugs in comparison to Diazepam.Methods: T Models used in the experiment are Grip Strength Test, Rota Rod Method, Beam Walk Test, Photoactometer Test. Animals were divided into 6 groups of 6 rats each: Group 1: Control group treated with normal saline (0.1 ml/10gm), Group 2: Standard-15mg/kg of Diazepam, Group 3:T1-60 mg/kg of Gabapentin, Group 4:T2-10 mg/kg of Pregabalin, Group 5:T3-60 mg/kg of Gabapentin+Diazepam, Group 6:T4- 10 mg/kg of Pregabalin+Diazepam. Mean and standard deviation was calculated for each group. One way ANOVA was used for multiple group comparisons followed by post hoc Tukey’s test for statistical significance between the groups.Results: Treatment with the above test drugs produced significant muscle relaxation and caused decreased fall off, sliding time, increase climbing time and decreased locomotor activity in all models indicating motor incoordination. The results obtained from both standard and test groups showed a highly significant difference in muscle relaxation when compared with the control group.Conclusions: The test drugs showed skeletal muscle relaxant property in rats comparable to Diazepam. In view of these results, it can open a new avenue for these drugs to be used as skeletal muscle relaxants after conducting clinical trials

Modification of silicon carbide fibers for use in SiC/Ti composites

The degradation of silicon carbide fibers during exposure to conditions typical of composite fabrication was investigated. The tensile strength of pristine fibers and fibers sputtered with thin metal coatings were determined before and after treatment at 870 C for one hour in vacuum. Each fiber strength distribution was related by an analytical procedure to a projected composite ultimate tensile strength (PC UTS). The results indicate that a thin aluminum diffusion barrier can yield a 150 percent increase in PC UTS over the baseline SiC/Ti system

Inflaton Decay in an Alpha Vacuum

We study the alpha vacua of de Sitter space by considering the decay rate of the inflaton field coupled to a scalar field placed in an alpha vacuum. We find an {\em alpha dependent} Bose enhancement relative to the Bunch-Davies vacuum and, surprisingly, no non-renormalizable divergences. We also consider a modified alpha dependent time ordering prescription for the Feynman propagator and show that it leads to an alpha independent result. This result suggests that it may be possible to calculate in any alpha vacuum if we employ the appropriate causality preserving prescription.Comment: 16 pages, 1 figure, Revtex 4 preprin
