Existing priorsbased approaches have limited performance in many situations due to their hand-designed features. In this paper, we propose an effective convolutional neural network (CNN) based approach for underwater image restoration, which consists of a transmission estimation network (T-network) and a global ambient light estimation network (A-network). By learning the relationship between the underwater scenes and their corresponding blue channel transmission map and global ambient light respectively, we can recover and enhance the underwater images with an underwater optical imaging model. In T-network, we use crosslayer connection and multi-scale estimation to prevent halo artifacts and to preserve edge features. Moreover, we develop a new underwater image synthetic method for training, which can simulate underwater images captured in various underwater environments. Experimental results of synthetic and ...

With the mushrooming of multi-story apartments, the backyard space of yester years is nothing but a dream. Although sincere efforts are put in garbage clearance, yet cleanliness and accuracy are still lacking under Indian circumstances. Usefulness of kitchen refuse for composting was an old world scenario, where a backyard with an orchard, flower garden and kitchen garden was made use of for the thrown kitchen refuse. Presently many urbanites want to make the best use of kitchen refuse by converting it into utilizable manure from the point of view of ecofriendliness and create a pollution-free zone. Though a method already exists, the problem of leachate, smell and fly menace limits the technology of aerobic composting and vermicomposting. In the present paper a simple use of Leachate Absorbing Raw Material (LARM) either as cocopith, bagasse and or jute...

With the mushrooming of multy-story apartments, the space of the backyard of the yester years is nothing but a dream. Although an immense effort is put in, in clearance of garbage yet cleanliness and time accuracy is still a wanting scenario under Indian circumstances. Usefulness of kitchen refuse as composting was an old world scenario wherein a backyard with an orchard, a flower garden and kitchen garden was made use of the thrown kitchen refuse. Currently many urbanites certainly want to make use of kitchen refuse into utilizable manure from the point of eco-friendly, pollution-free zone; however a method although exist the problem of leachate, smell and fly menace limits the technology of aerobic composting and vermicomposting. In the present paper a simple use of LARM either as cocopith, bagasse and or jute waste has solved the problem of leachat...

Noted secondary effects of recommended chemical fertilizers and a dearth of farmyard manure [FYM] has led to depend on sewage sludge found in abundance for the cultivable lands. There are a number of constraints associated with the application of both liquid and dewatered sewage sludge on to the land – like, difficulty to spread uniformly on land, storage problems and the human pathogenic organisms’ eggs. Vermicomposting of sewage sludge is a well-known fact as a bioremedial process, for better quality in terms of stabilized nutrients, keeping quality and ease in handling. Earthworm Eudrilus eugeniae is a well-known species used extensively in India for solid organic wastes. In the experimental studies it was observed that these worms needed more time to convert the sewage sludge without any admixes. The cause is being ni...

The study of bioenergetics is relevant for both basic sciences as well as applied fields to assess the environmental impact on the economically important organisms like compost earthworms. In the present research an experiment has been implemented to study the utilization of food budget in the tropical compost earthworm Eudrilus eugeniae under regular seasonal patterns of rainy, winter and summer by providing ad libitum partially-aerobically decomposed cattle dung. This study was done to know the effect of season on the feeding, defecation and cocoon production of the earthworms for its best utilization from the point of commercialization under three agro-climatic conditions. The fate of eaten food from hatchlings to post reproductive periods were documented for the study of growth period, growth, food consumption,...

The different photoperiods stipulated were Natural 12hr Light: 12hr Dark (natural LD 12:12), Reversal of 12hr Light: 12hr Dark ( reversal LD 12:12), 24hr Light source (L 24), 24hr Dark (D 24) and control set (natural rhythm) were experienced by E. eugeniae in the course of the study. The experiments were carried out during the ambient winter (26 degree C + 2 ) and all clitellate worms showed varied feeding and defecation activities. Worms fed actively only during night times under natural LD 12: 12. when exposed to reversal LD 12:12 revealed acclimatization to the changed conditions of day and night by the end of 2nd week and started feeding voraciously. Worms that were maintained in D 24 showed enhanced feeding rate with increased biomass over the worms that were maintained in natural LD 12:12 and natural rhythm (control se...

One of the compost earthworm, Eudrilus eugeniae (picked up among 3,000+ species)...

They remain throughout the composting period (say 60 - 90 days). At the end of the composting (or on completion) some of them die as such. When they are alive or dead ants do not scavenge them. Due to very thick chitinous coat/mantle the maggot doesn't decompose rather gets thoroughly dried up into powder form (at least to the naked eye). However, these maggots turn/transform into big insects of friendly nature. On touch they simply fly away and do not turn up.
