Abstract

Asset monitoring in construction sites is an intricate, manually intensive task, that can highly benefit from automated solutions engineered using deep neural networks. We use Single-Shot Multibox Detector --- SSD, for its fine balance between speed and accuracy, to leverage ubiquitously available images and videos from the surveillance cameras on the construction sites and automate the monitoring tasks, hence enabling project managers to better track the performance and optimize the utilization of each resource. We propose to improve the performance of SSD by clustering the predicted boxes instead of a greedy approach like non-maximum suppression. We do so using Affinity Propagation Clustering --- APC to cluster the predicted boxes based on the similarity index computed using the spatial features as well as location of predicted boxes. In our attempts, we have been able to improve the mean average precision of SSD by 3.77% on custom dataset consist of images from construction sites and by 1.67% on PASCAL VOC Challenge., Comment: 6 pages, 4 figures, to appear in the Proceedings of the ISC2 2018, 16-19 September 2018, Kansas, USA

Abstract

The booming consciousness of the problems associated with biodegradable solid waste generation has driven the globe for the reutilization of organic waste wherever it is generated, lowering trash volumes and transportation costs. The present study deals with the zero waste approach that endorses the fostering of sustainable long-term socio-economic and environmental benefits by transforming biodegradable solid waste into biofertilizers. A novel consolidated bioprocessing approach is adopted which in particular relates to the hydrolysis of biodegradable municipal solid waste by hydrolytic enzymes produced by Aspergillus nigerS-30 and the growth of biofertilizer non-pathogenic strain of Klebsiella pneumoniaeAP-407 in nutrients present in the hydrolysate to prepare liquid biofertilizer and carrier-based solid biofertilizer formulations with 1.03 × 1012cfu/ml and 1.03 × 1012cfu/g, respectively. Furthermore, the formulations significantly enhanced the % oxidizable organic carbon, available phosphate (P2O5), available potassium (K2O), ammonical nitrogen (NH3-N), and nitrate nitrogen (NO3-N) in soil and chlorophyll content of plant leaves of Brassica juncea. It is further appreciated that the process is economically attractive as no exogenous enzyme loadings are required, no exogenous carrier substance is added, and the entire process is carried out in a single fermenter vessel.

Abstract

In this paper we introduce the concept of higher-order (F, α, β ρ, d)-convexity with respect to a differentiable function K. Based on this generalized convexity, sufficient optimality conditions for a nonlinear programming problem (NP) are obtained. Duality relations for Mond-Weir and Wolfe duals of (NP) have also been discussed. These duality results are then applied to nonlinear fractional programming problems. [ABSTRACT FROM AUTHOR]

23. Sufficiency and duality in nondifferentiable multiobjective fractional programming with higher-order (V , α , ρ , θ) -invexity

Author

Gulati, T.R. and Saini, Himani

Abstract

In the present paper, the concept of higher-order (V , α , ρ , θ) invexity is used to study higher-order duality for a nondifferentiable multiobjective fractional programming problem (MFP). We first obtain a result giving higher-order (V, α, ρ, θ)-invexity of the ratio of two functions. This result is then used to drive sufficient optimality conditions for an efficient solution of (MFP). Moreover, duality theorems are established for Mond-Weir type higher-order dual of (MFP).

Abstract

Background: Extra-pituitary birth defect (EPBD) in children with congenital hypopituitarism is largely unknown., Objective: The study aims to evaluate the incidence and pattern of EPBD in children with congenital hypopituitarism and to evaluate whether it can serve as a clue to diagnose this condition., Patients and Methods: Retrospective analysis of hospital record of patients of short stature due to various etiology from which patients with congenital hypopituitarism with age ≥18 years were recruited for the analysis. Clinical, hormonal, radiological and ocular electrophysiological studies were done in all patients and all EPBD were noted., Results: Twenty seven patients (79%) had multiple pituitary hormone deficiency (MPHD) of which growth hormone was universal followed by gonadotropin (62%), TSH (59%), ACTH (44%) and prolactin (12%). Nineteen patients (56%) had multiple EPBD in various combinations. Twenty three ocular abnormalities were present in 12 patients (35%). Nine patients (26%) had other associated EPBD along with ocular abnormalities while 3 had ocular abnormalities without any other associated birth defect. Skeletal defects were present in 10 patients (29.5%). On the contrary, 5 patients in the EPBD group had total 15 visual defects. The most common abnormality of the visual system were abnormal visual evoke response (VER, 18%), followed by strabismus (15%), visual acuity (VA, 12%), electroretinogram (ERG) and electrooculogram (EOG) 8% each and visual field defect 6%. There was a trend towards early age at presentation with EPBD., Conclusions: Presence of EPBD in a short child is a sensitive marker to diagnose congenital hypopituitarism. Subtle abnormalities of visual pathway without absent septum pellucidum or midline brain defects were common., (© Journal of the Association of Physicians of India 2011.)
