Is dilution of Standards in housing using conventional materials as against using alternative materials like bamboo a solution to increasing affordability among the urban poor?[ ]


“Anything less than a ‘pucca’ (Permanent) house, is not a house at all”, is the myth which is rampant among the urban poor, even while they continue to live in a “kuccha”(Temporary) house for decades.The myth is such because even the pro-viders of housing believe in it. A “kuccha” ” (Temporary) house is rendered valueless, hence remains temporary, subserviced and figures as an inhabitable house in the national surveys. So much so that it is a house that attracts political and national attention in the form of an “unauthorised construction” because it sits on a piece of land which was meant for some other purpose. A “Pucca” (Permanent) house uses conventional materials, which have a history of becoming costlier over time; a “kuccha” house is valueless. Under the circumstances the urban poor are left at the mercy of local bodies for their survival, on urban land.

Exploring Highly Structure Similar Protein Sequence Motifs using Granular Computing Model based on Adaptive FCM[ ]


Protein sequence motifs are very important to the analysis of biologically signi?cant conserved regions to determine the conformation, function and activities of the proteins. These sequence motifs are identified from protein sequence segments generated from large number of protein sequences. All generated sequence segments may not yield potential motif patterns. In this paper, short recurring segments of proteins are explored by utilizing a granular computing strategy. Initially, Fuzzy C-Means (FCM) and Adaptive Fuzzy C-Means clustering algorithms (AFCM) are used to separate the whole dataset into several smaller informational granules and then succeeded by K-Means and Rough K-Means clustering algorithms on each granule to obtain the final results. By comparing the results of two different granular techniques shows that Adaptive FCM granular with Rough K-Means clustering is capable to capture better motif patterns suggests that our granular computing model which combined AFCM granular with Rough K-Means have a high chance to be applied in some other bioinformatics research fields.

Aquaculture Benefits of Macroalgae for Green energy Production and Climate change Mitigation[ ]


It is an established fact that climate change caused by human-induced concentrations of greenhouse gases (GHG), especially CO2 emissions, are increasing in the earth’s atmosphere and is one of the greatest challenges the world is currently facing. Algae play significant roles in normal functioning of the atmospheric environment and are important candidates for climate change mitigation. Macroalgae (over 20 commercial seaweed species) are the second most cultured species of aquatic organisms after finfish. More than 92 % of the world’s macroalgae production comes from mariculture. Macroalgae have a higher photosynthetic efficacy (6 – 8 %) than that of terrestrial plants (1.8 – 2.2 %). An investigation into seaweed as a food source for the South African abalone (Haliotis midae L.) has led to an increased knowledge of its fisheries and aquaculture conditions. Ulva spp are grown on a large scale in paddle wheel ponds and is currently South Africa’s largest aquaculture product. Its growth rate, ease of harvesting, resistance to contamination by other algal species and minimal production loss make it preferable to microalgae and to other macroalgae for large scale renewable energy production and CO2 capturing systems. Of all macroalgae, Ulva spp are exciting prospects in terms of energy efficiency. Findings have further revealed that biotransformation of Ulva to Liquefied Petroleum Gas (LPG) is viable. Large scale aquaculture production of Ulva spp is occurring in South Africa and biotransformation to LPG is possible and economically feasible with additional benefits from farming activities including bioremediation, ocean de-acidification, mineral-rich plant stimulants, and the capturing of atmospheric and dissolved CO2 during growth to assist in climate change mitigation.

Niching Estimation of Distribution Algorithm Based on Fuzzy Clustering for Multi-mode Resource-constrained Project Scheduling Problems[ ]


This paper proposes a novel niching estimation of distribution algorithm (EDA) based on fuzzy c-means (FCM) clustering for solving the multi-mode resource-constrained project scheduling problem (MRCPSP). FCM clustering is employed to partition the population into niches to avoid premature convergence of the EDA. Then, the niche capacity is determined by Boltzmann scheme according to the adaptive clearing radius and niche fitness. Besides, a restart up policy is employed based on a new diversity measure. A random walk local search is applied based on delete-then-insert operator (DIRW) to achieve a trade-off between exploration and exploitation abilities. The proposed algorithm is tested and evaluated using benchmark test problems of the project scheduling problem library PSPLIB, and compared with the standard EDA algorithm. Simulation results demonstrate the effectiveness of the proposed algorithm, and outperform the standard EDA.
