In the cyclo­hexene ring of the title compound, C23H20BrNO3S, the -(CH2)4- atoms are positionally disordered [occupancy ratio = 0.753 (6):0.247 (6)]. The ring has a half-chair conformation for both the major and minor components. The dihedral angles between the mean plane of the thio­phene ring and those of the benzene and phenyl rings are 35.2 (4) and 57.7 (3)°, respectively. The planes of the two aryl rings are twisted with respect to each other by 86.4 (6)°. In the mol­ecule, there is an O-H...N hydrogen bond forming an S(6) ring motif. In the crystal, mol­ecules are linked via C-H...O hydrogen bonds, forming chains parallel to [100].Publisher PDFPeer reviewe

Template Matching Method for Recognition of Stone Inscripted Kannada Characters of Different Time Frames Based on Correlation Analysis

Stone inscripted literature speaks about the history, language of different regions of the world. Preservation of such document through digitalization process is become very important. To stop degradation and missing further, the analysis of the same will through light on historical events of that region. In this connection present work proposes a simple method of digitization using ordinary digital camera further, the pre-processing algorithm is implemented to enhance the image and improve the readability. Here it recognizes the Kannada characters based on template matching. In this method is normally implemented by first picking template and then it  call the search image, then by simply comparing the  template over each point in the search image and it calculate the sum of products between the coefficient. Based on this calculated product value it recognizes the character.  Cross correlation technique is implemented in matching the characters coefficient. Experimental results shows, it demonstrates relatively high accuracy in recognizing Stone inscriptions characters of both Hoysala, Ganga time frames and with better time efficiency when compared to previous methods. DOI:http://dx.doi.org/10.11591/ijece.v4i5.633

Evaluation Of Conventional Digital Camera Scenes For Thematic Information Extraction.

The increasing availability of remote-sensing images, acquired periodically by satellite sensors on the same geo makes it extremely interesting to develop the monitoring systems capable of automatically producing and reg landcover maps of the considered site (Bruzzone, et ai., 2002)

Performance analysis of different matrix decomposition methods on face recognition

Applications using face biometric are ubiquitous in various domains. We propose an efficient method using Discrete Wavelet Transform (DWT), Extended Directional Binary codes (EDBC), three matrix decompositions and Singular Value Decomposition (SVD) for face recognition. The combined effect of Schur, Hessenberg and QR matrix decompositions are utilized with existing algorithm. The discrimination power between two different persons is justified using Average Overall Deviation (AOD) parameter. Fused EDBC and SVD features are considered for performance calculation. City-block and Euclidean Distance (ED) measure is used for matching. Performance is improved on YALE, GTAV and ORL face databases compared with existing methods

Design and Analysis of High-pressure Casing of a Steam Turbine

AbstractContact pressure and pretension in bolts-analysis has been made easier in recent years due to the availability of high computational capabilities and flexibility in the computational methods using finite element analysis. In the present work, one such analysis is carried out blending the hand calculations and steady-state finite element analysis to evaluate the contact pressure in a high pressure steam turbine casing. The work involves design considerations, design checks, validation and sensitivity analysis to achieve the design criteria to fulfill the structural requirements for mechanical integrity. During the last several years the primary changes to the design of steam turbines have focused on improving their efficiency, reliability and reducing operating costs. Siemens Power Generation, for example, has improved the overall efficiency and availability of its steam turbines by decreasing the steam flow energy losses in each of the steam turbines components. The steam turbine unit largely influences the efficiency and reliability of power stations. Any improvement in the design of steam turbine enables more efficient use of fuel and results in reduced cost. The high pressure steam at 565°C and 156bar pressure passes through the high pressure turbine. The exhaust steam from this section is returned to the boiler for reheating before being used. On leaving the boiler reheater, steam enters the intermediate pressure turbine at 565°C and 40.2bar pressure. From the intermediate pressure turbine, the steam continues its expansion in the three Low pressure turbines. The steam entering the turbine is at 306°C and 6.32bar. To get the most work out of the steam, the exhaust pressure is kept very low. The casing thus witnesses, energy of the steam turned into work in HP and IP stages. So, the design of the casing is a very important aspect

Experimental and Computational Simulation of producing ultra-fine grain Structure processed by CGP

In this research the constrained groove pressing (CGP) process as a severe plastic deformation (SPD) method was applied on commercially pure aluminum plates. According to the principle of CGP, a material is subjected to repetitive shear deformation by utilizing asymmetrically grooved dies and flat dies which are constrained by a channel. Each complete groove pre ssing pass consists of four pressing operation steps. Considering the geometry of the die, in each complete pass, a large amount of strain is induced into the specimen. In the present research the effects of the deformation passes on the mechanical propert ies of the specimens were tested by micro hardness tests. In addition, in order to investigate the material flow along the grooves in the CGP process, the finite element simulations were carried for one of the process. Our pproach involves computational simulation of the entire synthesis process for the optimization. Results show that the flow stress of the material and its hardness are affected by the number of passes. Post process of the finite element analysis showed that the real state of the CGP process is a combination of plane stress and plane strain conditions

Studie zur Qualität ökologisch erzeugter Lebensmittel unter besonderer Berücksichtigung des gesundheitlichen Verbraucherschutzes

400 Hühnereier aus ökologischer und konventioneller Produktion wurden mikrobiologisch untersucht. Weder Salmonella spp. noch Yersinia enterocolitica wurden isoliert. Bei 1 % der konventionell erzeugten Eier und 0,25 % der Ökoeier wurden koagulase-positive Staphylokokken auf der Schale festgestellt. Campylobacter spp. wurde aus einer gepoolten Probe von 3 ökologisch erzeugten Eiern isoliert. Hinsichtlich allgemeiner Qualitätsmerkmale zeigte sich, daß Ökoeier deutlich häufiger Verschmutzungen aufwiesen als Eier aus konventioneller Haltung, dagegen lag die Nachweisrate an Knickeiern in der Käfighaltung deutlich höher. Insgesamt kamen bei 13 % der konventionell erzeugten Eier und bei 12 % der Ökoeier Überschreitungen von gesetzlich nicht festgelegten Richtwerten an Kokzidiostatika vor. In 400 Schweinefleischproben wurden weder Salmonella spp., Yersinia enterocolitica noch Campylobacter spp. isoliert. Listeria monocytogenes und koagulase- positive Staphylokokken waren regelmäßig nachzuweisen, lagen jedoch nicht in erhöhten Konzentrationen vor. 53 % der Ökofleischproben wiesen eine erhöhte aerobe, mesophile Gesamtkeimzahl auf, bei den konventionellen Erzeugnissen lag die Rate bei 35,5 %. Auch Enterobacteriaceae waren bei den Ökoprodukten geringgradig häufiger in erhöhten Keimzahlen nachzuweisen als beim konventionellen Fleisch. Die Isolierung shiga-toxinbildender E. coli (STEC) erfolgte in einer Ökoschweinefleischprobe. Zusätzlich wurde die Hälfte der Fleischproben auf das Vorkommen bestimmter Antibiotika hin untersucht. In keiner der 100 ökologischen und in 4 der 100 konventionellen Fleischproben wurden einer oder mehrere dieser Stoffe nachgewiesen. Der gesetzliche Höchstwert von 100 µg/kg wurde nicht überschritten. Die Prüfung auf Toxoplasma gondii erfolgte bei allen Fleischproben sowie bei 129 ökologisch und 133 konventionell erzeugten Rohwürsten. Ökologisch erzeugte Schweinefleischproben (9 %) bzw. Rohwürste (1,6 %) wiesen im Vergleich zu den konventionell erzeugten Produkten (Schweinefleisch 2,5 %, Rohwurst 0 %) öfter positive Toxoplasma-Antikörpertiter auf. Die Prüfung von jeweils 124 Rohwürsten aus der ökologischen sowie der konventionellen Produktion auf das Vorkommen von Yersinia enterocolitica und Campylobacter spp. ergab ein negatives Ergebnis

Transcendence over Diversity: black women in the academy

Universities, like many major public institutions have embraced the notion of ‘diversity’ virtually uncritically- it is seen as a moral ‘good in itself’. But what happens to those who come to represent ‘diversity’- the black and minority ethnic groups targeted to increase the institutions thirst for global markets and aversion to accusations of institutional racism? Drawing on existing literature which analyses the process of marginalization in higher education, this paper explores the individual costs to black and female academic staff regardless of the discourse on diversity. However despite the exclusion of staff, black and minority ethnic women are also entering higher education in relatively large numbers as students. Such ‘grassroots’ educational urgency transcends the dominant discourse on diversity and challenges presumptions inherent in top down initiatives such as ‘widening participation’. Such a collective movement from the bottom up shows the importance of understanding black female agency when unpacking the complex dynamics of gendered and racialised exclusion. Black women’s desire for education and learning makes possible a reclaiming of higher education from creeping instrumentalism and reinstates it as a radical site of resistance and refutation
