Wavelet spatial scaling for educing dynamic structures in turbulent open cavity flows
Seena, Abu,Jin Sung, Hyung Elsevier 2011 Journal of fluids and structures Vol.27 No.7
<P><B>Abstract</B></P><P>In this work a methodology was developed for the selection of wavelet spatial scales to educe dynamic structures in turbulent cavity flows. The wavelet transform was applied to both the temporal signal and spatial fields to extract structures from the oscillating shear layer. The dominant frequencies were identified from the temporal transform of the shear layer oscillations, and then the corresponding wavelength was obtained using the relation <I>U</I><SUB><I>c</I></SUB><I>T</I>=<I>λ</I> at each frequency. The wavelet spatial scaling was examined and a one-to-one relationship was established with respect to the wavelength. At each spatial scale, the transformed images of vorticity, velocity, and pressure fluctuations captured the vortical structures. Using this methodology, the dynamic vortical structures were extracted from the turbulent open cavity flows. Energy analysis was performed to examine the contributions of each structure.</P>

Background and Purpose Studies of cases of Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD) confirmed by multiplex ligation-dependent probe amplification (MLPA) have determined the clinical characteristics, genotype, and relations between the reading frame and phenotype for different countries. This is the first such study from India. Methods A retrospective genotype-phenotype analysis of 317 MLPA-confirmed patients with DMD or BMD who visited the neuromuscular clinic of a quaternary referral center in southern India. Results The 317 patients comprised 279 cases of DMD (88%), 32 of BMD (10.1%), and 6 of intermediate phenotype (1.9%). Deletions accounted for 91.8% of cases, with duplications causing the remaining 8.2%. There were 254 cases of DMD (91%) with deletions and 25 (9%) due to duplications, and 31 cases (96.8%) of BMD with deletions and 1 (3.2%) due to duplication. All six cases of intermediate type were due to deletions. The most-common mutation was a single-exon deletion. Deletions of six or fewer exons constituted 68.8% of cases. The deletion of exon 50 was the most common. The reading-frame rule held in 90% of DMD and 94% of BMD cases. A tendency toward a lower IQ and earlier wheelchair dependence was observed with distal exon deletions, though a significant correlation was not found. Conclusions The reading-frame rule held in 90% to 94% of children, which is consistent with reports from other parts of the world. However, testing by MLPA is a limitation, and advanced sequencing methods including analysis of the structure of mutant dystrophin is needed for more-accurate assessments of the genotype-phenotype correlation.
Turbulent boundary layers over rod- and cube-roughened walls
Lee, Jae Hwa,Seena, Abu,Lee, Seung-hyun,Sung, Hyung Jin Informa UK (TaylorFrancis) 2012 Journal of turbulence Vol.13 No.-
<P>Direct numerical simulations (DNSs) of spatially developing turbulent boundary layers (TBLs) over two-dimensional (2D) rod-roughened walls and three-dimensional (3D) cube-roughened walls were performed to investigate the effects of the streamwise spacing of roughness elements on the properties of the TBLs. The inspection of the Reynolds stresses showed that except for the 2D rough walls with p(x)/k = 2 and 3, the effects of the roughness on the 2D and 3D rough walls extend to the outer layer and that the magnitude of the Reynolds stresses in the outer layer increases in proportional to p(x)/k. However, such results do not account for the variations with p(x)/k in the form drag and roughness function, which have maximum values at p(x)/k = 8 and 4 for the 2D and 3D rough walls, respectively. Finally, we examined turbulent structure through instantaneous analysis, linear stochastic estimation, and dynamic mode decomposition to the time-evolving flow fields to scrutinize the spatial organization of the outer-layer structures over several different rough walls.</P>
High performance fibre reinforced cement concrete slender structural walls
Ganesan, N.,Indira, P.V.,Seena., P. Techno-Press 2014 Advances in concrete construction Vol.2 No.4
In the design of reinforced concrete structural walls, in order to ensure adequate inelastic displacement behaviour and to sustain deformation demands imposed by strong ground motions, special reinforcement is considered while designing. However, these would lead to severe reinforcement congestion and difficulties during construction. Addition of randomly distributed discrete fibres in concrete improves the flexural behaviour of structural elements because of its enhanced tensile properties and this leads to reduction in congestion. This paper deals with effect of addition of steel fibres on the behavior of high performance fibre reinforced cement concrete (HPFRCC) slender structural walls with the different volume fractions of steel fibres. The specimens were subjected to quasi static lateral reverse cyclic loading until failure. The high performance concrete (HPC) used was obtained based on the guidelines given in ACI 211.1 which was further modified by prof.Aitcin (1998). The volume fraction of the fibres used in this study varied from 0 to 1% with an increment of 0.5%. The results were analysed critically and appraised. The study indicates that the addition of steel fibres in the HPC structural walls enhances the first crack load, strength, initial stiffness and energy dissipation capacity.

Background and Purpose Pathogenic variants in the myopalladin gene (MYPN) are known to cause mildly progressive nemaline/cap myopathy. Only nine cases have been reported in the English literature. Methods A detailed evaluation was conducted of the clinical, muscle magnetic resonance imaging (MRI), and genetic findings of two unrelated adults with MYPN-related cap myopathy. Genetic analysis was performed using whole-exome sequencing. MRI was performed on a 1.5-T device in patient 1. Results Two unrelated adults born to consanguineous parents, a 28-year-old male and a 23-year-old female, were diagnosed with pathogenic variants in MYPN that cause cap myopathy. Both patients presented with early-onset, insidiously progressive, and minimally disabling proximodistal weakness with mild ptosis, facial weakness, and bulbar symptoms. Patient 1 had a prominent foot drop from the onset. Both patients were followed up at age 30 years, at which point serum creatine kinase concentrations were minimally elevated. There were no cardiac symptoms; electrocardiograms and two-dimensional echocardiograms were normal in both patients. Muscle MRI revealed preferential involvement of the glutei, posterior thigh muscles, and anterior leg muscles. Whole-exome sequencing revealed significant homozygous splicesite variants in both of the probands, affecting intron 10 of MYPN: c.1973+1G>C (patient 1) and c.1974-2A>C (patient 2). Conclusions This study elaborates on two patients with homozygous MYPN pathogenic variants, presenting as slowly progressive congenital myopathy. These patients are only the tenth and eleventh cases reported in the English literature, and the first from South Asia. The clinical phenotype reiterates the mild form of nemaline rod/cap myopathy. A comprehensive literature review is presented.
Effect of microorganism on engineering properties of cohesive soils
Yasodian, Sheela Evangeline,Dutta, Rakesh Kumar,Mathew, Lea,Anima, T.M.,Seena, S.B. Techno-Press 2012 Geomechanics & engineering Vol.4 No.2
This paper presents the study of the effect of microorganism Bacillus pasteurii on the properties such as Atterbergs' limit and unconfined compressive strength of cohesive soils. The results of this study reveal that the liquid limit and plasticity index for all clay soils decreased and the unconfined compressive strength increased. Decrease in plasticity index is very high for Kuttanad clay followed by bentonite and laterite. The unconfined compressive strength increased for all the soils. The increase was high for Kuttanad soil and low for laterite soil. After 24 h of treatment the improvement in the soil properties is comparatively less. Besides the specific bacteria selected Bacillus pasteurii, other microorganisms may also be taking part in calcite precipitation thereby causing soil cementation. But the naturally present microorganisms alone cannot work on the calcite precipitation.
