Scientific Study of Balance (Al-Mīzān) in the Light of Sūrah Al-Rahmān

This article is an attempt to elaborate the phenomenon of equilibrium prevailing everywhere in the microcosmic and macrocosmic systems associated with universal stability and rhythm. It has been accentuated what is beautifully illuminated in the beginning verses of Sūrah Al-Rahmān successively regarding balance that invites one’s thought towards the well controlled cosmic system as well as with the concept of balance by means of different manners as identified by exegetes and scholars concerning daily life i.e. From simple and common to that of complex issues and intricacies. Qualitative method has been employed for this research while some aspects have also been handled in accordance with quantitative approach. Article also emphasized the series of cause and effect nexus may be declared as self explanatory episode an indication towards a Supreme Force whose widespread control and interference can’t be denied rationally. Sūrah beautifully pictured the physical and metaphysical sketch of balance having many dimensions from man to universe and vice versa as well as from both towards Ultimate Reality whose dominion is limitless where one has to follow peaceful living and to put oneself aside indulging any disruption from ordinary clash to that of nuclear war to be waged.

Automated Detection of Glaucoma from Fundus and Optical Coherence Tomography Images

Medical image analysis can play a substantial role in diagnosis of different medical problems. Glaucoma is an asymptomatic neurological disease. Oculists mostly use fundoscopy or OpticalCoherence-Tomography (O-C-T) to diagnose glaucoma.Fundoscopy can be used to analyse the external stratum of posterior part of the eye whereas, O-C-T imaging technology has the ability to analyse the internal stratums of posterior part of the eye.In this thesis, a Hybrid Computer Aided Diagnosis (H-CAD) system has been proposed that integrates both fundus and O-C-T imaging technologies for reliable diagnosis. Fundus module has a novel combination of hybrid structural and textural features. The system improves the decision making process after analysing a variety of glaucoma conditions. It further consists of two sub modules Hybrid Structural Feature-set (HSF) and Hybrid Texture Feature-set (HTF). HSF module calculates structural changes i.e. Cupto-Disc-Ratio (C-D-R) and classifies a sample using Support-Vector-Machine (S-V-M). HTF module analyses the textural properties of optic nerve head and again using S-V-M, makes a decision. In O-C-T module, C-D-R has been calculated on the base of the inner stratums of the retina. In the Cup Diameter Extraction (C-D-E) method, cup boundary has been marked on the base of Inner-Limiting-Membrane (I-L-M) stratum. The O-C-T module presents a new method to increase the accuracy of I-L-M stratum segmentation. It also introduces a new method to interpolate missing points on the extracted Upper-Surface of I-L-M stratum (?????). In addition, a novel technique to remove outliers from ????? has been applied. In Disc-Diameter-Extraction (D-D-E) process, Retinal-Pigment-Epithelium (R-P-E) stratum termination points have been used to locate disc margin. Earlier to R-P-E stratum segmentation, I-L-M stratum elimination has been done by a new approach to trace and eliminate I-L-M stratum. Finally, precise R-P-E stratum segmentation has been achieved on the base of new Thickness Value approximation technique. Furthermore, a novel standard for cup boundaries identification, on the base of mean value of R-P-E stratum terminations points is offered. A local-dataset of SD-O-C-T and fundus images annotated by four oculists has been used for evaluation of proposed H-CAD system. Each module ofH_CAD system classifies data independently. The final result of H-CAD system is determined based on decision of three diverse modules. The evaluations and results have shown that the final result of H_CAD system is more trustable than its contemporary automated models.
