Development of assistive technology to operate industrial grade sewing machines for differently-abled persons

An assistive technology to operate the sewing machine by hand has been developed and made suitable for differentlyabledpersons. This assistive device has been developed using two variant techniques, viz Technique-A and Technique-B.Technique-A involves electromechanical potentiometer control and Technique -B involves electrical servo motor control.The sewing machine is developed individually for each technique and tested in terms of machine handling factor, energyconsumption, maintenance and productivity. Based on comparative test results, the assistive device of Technique -B ishighly suitable and suggested for differently- abled persons. The operator performance in terms of single cycle time (SCT),efficiency, earning and skill level between normal persons and differently-abled persons has also been studied. With thisnew development, differently-abled persons can work and earn in garment industry like a normal sewing operator

Development of two novel methods using sensors to operate the industrial over-lock machine for loco-motor disabled person

In this research, two sensor-based methods have been developed to operate industrial over-lock sewing machine, especially for loco-motor disabled person. Generally, the over-lock sewing machine is operated using foot pedal and this sensor based method eliminates the foot pedal and use alternative ways to sew garment. The method-1 uses a flex-touch sensor and method-2 uses a textile sensor integrated wearable hand glove to operate the over-lock sewing machine. The seam efficiency of over-lock stitches performed using both the methods (1 & 2) has been assessed and compared with that of normal foot pedal method. A variety of woven and knitted garments are sewed by implementing both the methods, and results are evaluated to calibrate and standardize the sensors/methods to encourage loco-motor disabled persons as self-employed sewing operators

Isolation, Extraction, and Characterization of Verotoxin-producing Escherichia coli O157:H7 from Diarrheal Stool Samples

Background: Escherichia coli O157:H7 infection causes hemorrhagic colitis and is diagnosed based on symptoms such as cramps, stomach pain, and watery diarrhea. Shiga-like toxins (Verotoxin) produced by Escherichia coli O157:H7 damages endothelial cells of both kidney and brain, causing renal dysfunction and neurological problems. Methods: The present study focuses on identifying the prevalence of Verotoxin-producing Escherichia coli O157:H7 among diarrheal inpatients at Erode Government Hospital, India, and its antibiogram. Further, the Verotoxins were characterized by using SDS-PAGE analysis. A total of 123 samples were collected both from diarrheal stools, and strains from 37 samples (43.02 %) were found to have the presence of E. coli.  The organisms were identified based on their colony morphology on various media, cell morphology, and biochemical tests. The Shiga-like toxin production was identified by non-fermentation of sorbitol on SMAC agar plates. Confirmation of Shiga-like toxin was performed using agglutination assay.  Results: In total, 12 isolates showed agglutination and these isolates were confirmed to be E. coli O157:H7. The molecular weight of the Verotoxin was found to be between 20 and 29 kD. The antibiogram profile of the four isolated strains against 10 standard antibiotics was determined. Conclusion: The results of this study show the occurrence of drug resistance on hemorrhagic colitis causing E. coli O157:H7

DBC based Face Recognition using DWT

The applications using face biometric has proved its reliability in last decade. In this paper, we propose DBC based Face Recognition using DWT (DBC- FR) model. The Poly-U Near Infra Red (NIR) database images are scanned and cropped to get only the face part in pre-processing. The face part is resized to 100*100 and DWT is applied to derive LL, LH, HL and HH subbands. The LL subband of size 50*50 is converted into 100 cells with 5*5 dimention of each cell. The Directional Binary Code (DBC) is applied on each 5*5 cell to derive 100 features. The Euclidian distance measure is used to compare the features of test image and database images. The proposed algorithm render better percentage recognition rate compared to the existing algorithm.Comment: 15 pages,9 figures, 4 table

Effect of Fe on the Martensitic Transition, Magnetic and Magnetocaloric Properties in Ni-Mn-In Melt-spun Ribbons

The effect of Fe on the martensitic transitions, magnetic and inverse magnetocaloric effect in Ni47Mn40-xFexIn13 ribbons (x = 1, 2, 3 and 5) has been investigated. All the ribbon compositions under study have shown the presence of austenite phase at room temperature. The variation of martensitic transition with the increase in Fe-content is non-monotonic. The thermal hysteresis of the martensitic transition increased with the increase in Fe-content. The martensitic transitions shifted to lower temperatures in the presence of high magnetic fields. A maximum magnetic entropy change (∆SM) of 50 Jkg-1K-1 has been achieved in the Ni47Mn38Fe2In13 (x = 1) ribbon at 282 K for an applied field of 5 T

ORFanID: A Web-Based Search Engine for the Discovery and Identification of Orphan and Taxonomically Restricted Genes

With the multiplicity of genomes sequenced today, it has been shown that significant percentages of genes in any given taxon do not possess orthologous sequences in other taxa. These sequences are typically designated as orphans/ORFans when found as singletons in one species only or taxonomically restricted genes (TRGs) when found at higher taxonomic ranks. Quantitative and collective studies of these genes are necessary for understanding their biological origins. Currently, orphan gene identifying software is limited, and those previously available are either not functional, are limited in their database search range, or are very complex algorithmically. Thus, an interested researcher studying orphan genes must harvest their data from many disparate sources. ORFanID is a graphical web-based search engine that efficiently finds both orphan genes and TRGs at all taxonomic levels, from DNA or amino acid sequences in the entire NCBI database cluster and other large bioinformatics repositories. This algorithm allows the easy identification of both orphan genes and TRGs using both nucleotide and protein sequences in any species of interest. ORFanID identifies genes unique to any taxonomic rank, from species to a domain, using standard NCBI systematic classifiers. The software allows for user control of the NCBI database search parameters. The results of the search are provided in a spreadsheet as well as a graphical display. All the tables in the software are sortable by column, and results can be easily filtered with fuzzy search functionality. In addition, the visual presentation is expandable and collapsible by taxonomy

A novel conductive sensor-based test method to measure longitudinal wicking of fabrics

This paper reports the development of novel vertical wicking instrument which is specially designed to measure the wicking behavior of textile fabrics precisely. The instrument is designed using T-shaped test frame fabricated with tribo-electric fibre glass and electrical conductivity sensors. The developed electrical conductive sensors are capable to measure the time taken for the vertical wicking of water through inter-fibre capillaries with respect to height. The wet fabric allows the electrical current flow between two conductive points of sensor and enables the IoT controller circuit to monitor the time taken for wicking. To improve the accuracy of measuring the wicking behavior, tribo-electric fibre glass is used. The tribo electric fibre glass has electrostatic charges on its surface and induces static cling effect. Static cling is the tendency of light objects such as fabrics to stick (cling) to other objects owing to static electricity. The static cling effect attracts the fabric test sample to make it in contact with conductivity sensor array. The wicking process is carried out without causing obstruction to the movement of water through inter-fibre capillaries. The accuracy of the measured data obtained from the novel instrument is compared with the data of manual standard test procedure (R2> 0.97). The comparison shows that the developed instrument produces more reliable results
