Unicode font is used in coding system that assign a unique code to every symbol of scripts irrespective of their platform, and language. The Greek Unicoder receives 16-bit hexadecimal code of alphabet. The device has been designed to convert Greek language into different languages that our people could understand. This Unicode reader code has been implemented on 28nm FPGA platform called Kintex-7 FPGA. In this paper we are using frequency scaling technique and Design goal. In this paper power analysis is our main concern and we have studied about the power analysis at different frequencies keeping the temperature constant at 25 degree Celsius and maintaining the constant air flow.

Rahul K. Verma,Yuki Ogihara,Toshihiko Kuwabara,Kwansoo Chung 한국소성가공학회 2011 기타자료 Vol.2011 No.8

In this work, as non-proportional/non-monotonous deformation experiments, two-stage and tension-compression-tension uniaxial tests were performed, respectively, for a cold rolled ultra high strength dual phase steel sheet: DP780. Deformation behaviors under such deformation paths were found different than those of the ultra low carbon single phase steels observed by Verma et al. (Int. J. Plast. 2011, 82-101). To model the newly observed deformation behaviors, the combined type constitutive law previously proposed by Verma et al. (Int. J. Plast. 2011, 82-101) was successfully applied here. Permanent softening observed during reverse loading was properly characterized into the isotropic and kinematic hardening parts of the hardening law using tension-compression-tension test data. The cross effect observed in two-stage tests was also effectively incorporated into the constitutive law.

Purpose: The present study was aimed to investigate the variation of soft palate morphology in different age and gender groups. The correlations of radiographic velar length (VL), velar width (VW), pharyngeal depth (PD), and Need's ratio with soft palate variants were also studied in the North Indian subpopulation. Materials and Methods: The study sample consisted of 300 subjects aged between 15 and 45 (mean: 31.32) years. The velar morphology on lateral cephalograms was examined and grouped into six types. The results obtained were subjected to a statistical analysis to find the correlation between variants of the soft palate with gender and different age groups. Results: The most frequent type of soft palate was leaf shaped (48.7%), and the least common was crook shaped (3.0%) among both the genders and various age groups, showing a significant correlation. The mean VL, VW, and PD values were significantly higher in males and significantly correlated with the types of soft palate. A significant correlation was observed between the mean VL, VW, PD, and Need's ratio with various age groups, showing an inconsistent pattern with an increase in age. The types of soft palate, gender, and Need's ratio were also significantly correlated, with an overall higher mean value of the Need's ratio among female subjects and the S-shaped soft palate. Conclusion: The knowledge of a varied spectrum of velar morphology and the variants of the soft palate help in a better understanding of the velopharyngeal closure and craniofacial anomalies.

Jayeeta Verma,Sidharth Verma,Sumanthini V Margasahayam 대한치과마취과학회 2022 Journal of Dental Anesthesia and Pain Medicine Vol.22 No.5

Background: Postoperative endodontic pain is an enigma for the dentist. This study aimed to evaluate the analgesic effect of 300 mg gabapentin or 75 mg pregabalin in reducing postoperative endodontic pain compared with a placebo. Methods: Ninety patients who needed root canal treatment with an initial numerical rating scale (NRS) pain score of > 4 (T0) were randomly divided into three groups (n=30). Patients were then administered either 300 mg gabapentin (group A), 75 mg pregabalin (group B), or a placebo (group C) 30 min prior to the start of endodontic treatment. A single operator performed single-visit endodontics, and pain was evaluated immediately after endodontic treatment (T1) and at 4 h (T2), 8 h (T3), 12 h (T4), 24 h (T5), 48 h (T6), and 72 h (T7) using the NRS. Ibuprofen/paracetamol (400 mg/325 mg) was administered as a rescue dose if needed. Results: Pregabalin performed significantly better when compared with gabapentin at all time points except at 72 h after treatment (P=0.170). The placebo group showed significantly higher pain scores than the other two groups. The percentage of pain relief was maximum for pregabalin (92.1%), followed by gabapentin (87.6%) and placebo (69.1%) at 72 h after treatment completion. Conclusion: This study showed that pretreatment with a single dose of pregabalin and gabapentin both had greater analgesic effects than a placebo. They can be effectively used to reduce postoperative endodontic pain.

Material Modeling and Springback Prediction of Ultra Thin Austenitic Stainless Steel Sheet

Rahul K. Verma,Satoko Murakoso,Kwansoo Chung,Toshihiko Kuwabara 한국소성가공학회 2010 기타자료 Vol.2010 No.6

The constitutive model with combined isotropic-kinematic hardening along with hardening stagnation (or permanent softening) [Verma, Kuwabara, Chung, Haldar: Int. J. Plasticity (submitted)] was used here for modeling the tension-compression behaviors of a 0.1 mm thick austenitic stainless steel sheet (SUS304), which was observed in a recent work [Kuwabara and Murakoso: Proc. CIRP 2010 Conf. (submitted)]. Springback was also experimentally measured for a shallow drawn rectangular cup here and it was verified using the above model. It was found that this model can successfully predict the Bauschinger effect and hardening stagnation. As for springback, it was found that in this particular case it depends on, other than the material model, factors like boundary conditions, in the finite element analysis (FEA), during unloading. It was also observed that incorporation of the Bauschinger effect and permanent softening is a key for accurate springback prediction and, therefore, the present model performs better than the one which is based only on isotropic hardening without any hardening stagnation.

Transport and Optical Properties of n-Butylamine + Alkanols (C3–C4) Mixtures for Enhanced CO2 Absorption

Verma Sweety,Gahlyan Suman,Bhagat Payal,Rani Manju,Rana Seetu,Lee Yongjin,Maken Sanjeev 한국화학공학회 2024 Korean Journal of Chemical Engineering Vol.41 No.3

Reducing carbon emissions has emerged as a critical challenge, and among various methods, solvent-based CO 2 capture technology is the most widely employed. Amines, particularly eff ective solvents for CO 2 capture, play a signifi cant role in this process. To advance this technology, it is essential to understand the thermodynamic properties of the interactions between the constituent components. In this study, we examined the deviation in dynamic viscosity ( Δ ), and the deviation in refractive index ( Δn D ) calculated from the measured and n D data for n -butylamine (NBA) with alkanol systems. The temperature range for our study was 298.15–318.15 K. We utilized the Ab-initio approach for Δ data analysis. Our fi ndings revealed that the depolymerization power of alkanol is dependent on the unlike interactions. Furthermore, we employed various correlations/mixing rules to predict the as well as n D values from the experimental pure components data. The standard deviation was utilized to express the predictive abilities of these correlations.

Heterobeltiotic Genetic Interaction between Congenic and Syngenic Breeds of Silkworm, Bombyx mori L.

Verma A. K.,Chattopadhyay G. K.,Sengupta M.,Das S. K.,Sarkar A. K. Korean Society of Sericultural Science 2005 International Journal of Industrial Entomology Vol.11 No.2

To determine the level of heterosis, higher cocoon shell weight multivoltine congenic lines (Con. L) and bivoltine syngenic lines (Syn. L) of silkworm were used for crosses. First filial generations $(F_1s)$ expressed heterobeltiotic genetic interaction at significant magnitude (p < 0.01) for single cocoon shell weight (SCSW). The other linked characters viz., single cocoon weight (SCW) and yield by weight per 10, 000 larvae were also significantly higher (p < 0.01) than the better parental lines. All the hybrids showed significant improvement for these aforesaid characters over standard heterosis (Standard check). The reeling parameters viz., filament length, raw silk, neatness, cohesionstrokes etc, also showed improvement among the hybrids than check in congenial environment. Overall results suggested that the cross between congenic and syngenic lines provide better heterosis with good quality silk than conventional hybrids and may be used for commercial exploitation.

The effect of materialism, satisfaction and trust upon attitudinal loyalty: The case of denims

Verma Pranay 한국마케팅과학회 2021 마케팅과학연구 Vol.31 No.4

This paper investigates if attitudinal loyalty can be determined by materialism, satisfaction and trust of customers. Data collected from 721 Indian consumers were empirically tested using SEM for the reliability of the measurement model and relationships between constructs. This pioneer study demonstrates the assimilated influence of materialism, satisfaction and trust upon attitudinal loyalty. This research finds that materialism is significantly related to satisfaction. Satisfaction is also significantly associated with both trust and attitudinal loyalty. Further, trust was positively linked to attitudinal loyalty. Attitudinal loyalty varies with customer’s age and frequency of purchase, while trust varies due to gender, place of purchase, jeans life and cohabitance.

Modified Multi-Chaotic Systems that are Based on Pixel Shuffle for Image Encryption

Verma, Om Prakash,Nizam, Munazza,Ahmad, Musheer Korea Information Processing Society 2013 Journal of information processing systems Vol.9 No.2

Recently, a pixel-chaotic-shuffling (PCS) method has been proposed by Huang et al. for encrypting color images using multiple chaotic systems like the Henon, the Lorenz, the Chua, and the Rossler systems. All of which have great encryption performance. The authors claimed that their pixel-chaotic-shuffle (PCS) encryption method has high confidential security. However, the security analysis of the PCS method against the chosen-plaintext attack (CPA) and known-plaintext attack (KPA) performed by Solak et al. successfully breaks the PCS encryption scheme without knowing the secret key. In this paper we present an improved shuffling pattern for the plaintext image bits to make the cryptosystem proposed by Huang et al. resistant to chosen-plaintext attack and known-plaintext attack. The modifications in the existing PCS encryption method are proposed to improve its security performance against the potential attacks described above. The Number of Pixel Change Rate (NPCR), Unified Average Changed Intensity (UACI), information entropy, and correlation coefficient analysis are performed to evaluate the statistical performance of the modified PCS method. The simulation analysis reveals that the modified PCS method has better statistical features and is more resistant to attacks than Huang et al.'s PCS method.
