The irregularity in monsoon has severely affected the water availability at surface and sub-surface systems. Diminishing surface and sub-surface availability has not only decreased the water availability, but it additionally affected the ecosystem and increased disastrous situations like floods and droughts, resulting problems of stress on groundwater recharge. Groundwater recharge is a technique by which infiltrated water passes through the unsaturated region of groundwater and joins the water table. It is based upon soil type, land use land cover, geomorphology, geophysical and climate (viz. rainfall, temperature, humidity etc.) characteristics of a region. Over the years, due to variations in weather pattern and overexploitation of aquifers groundwater recharge has decreased and groundwater level has reduced in the most parts of the country. This has led to severe water deficit problems in several parts of the country. This can be solved by different direct and indirect methods of groundwater recharge technology. This technology can reduce the wastage of water and enhance groundwater availability for uses in different sector like irrigation, domestic and industrial uses.

The main objective of this study was to explore diversity of mammalian species in Shivapuri national Park (ShNP) through indirect method. Specific objectives were (i) to identify and describe characteristic features of different signs as key to species identification, and (ii) to determine occurrence and abundance of mammalian species based on the signs. Survey was conducted by walking through fixed 11 transect lines of total 229 km long, collecting and recording of footprints, feces, scrapes, scratches, shelters of burrows, calls and quills of mammals. Altogether 344 indirect signs were collected and observed through fixed transect lines and 25 signs through random searching of mammals from Kakani, Panimuhan, Shivapuri Peak, Baghdwar, Sundarijal, Chisapani and Manichur in ShNP. Basic characteristics of identified signs of different mamals as key to their identification have been described. The occurrence of species was confirmed through indirect signs and abundance was estimated on the basis of encounter rate (number/km/day) and relative frequency percentage of the signs. Among 20 species, 18 species belonging to six orderas and 14 families were recorded confirming by different indirect validation techniques. The study also identified large civet, a new record for ShNP. The highest percentage relative frequency (35%) and encounter rate (0.53/km) of signs of wild boar and house rat implied these species were the most abundant mammals in the park. This was followed by barking dear (17% and 0.26), common leopard (17% and 0.25), jungle cat (9.6% and 0.14), Himalayan squirrel and rhesus monkey, which were intermediate in abundance. Himalayan goral (6.7% and 0.10), Indian hare (4.3% and 0.06), yellow throated marten (4% and 0.06), golden jackal (3.5% and 0.05), large civit (2.6% and 0.04), black bear (0.3% and 0.004), Chinese pangolin, hanumal langur, royel's pika, porcupine and small mongoose were the least abundant species.

Successful deployment of cooperative decentralized model predicative control needs reasonably accurate subsystem interactions models. Processes in which open-loop tests are not permitted, closed-loop identification of subsystems interactions is crucial. An approach that combines the direct and indirect methods of closed-loop identification is proposed in this paper. It is shown that full dynamics of MIMO systems can be determined following a two-steps identification procedure. A representative case study is used to demonstrate the efficacy of the proposed approach.

AbstractGeological mapping of an unexposed area can be supported by indirect methods. Among these, the use of mushrooms as geobotanical indicators and the shallow-penetration electromagnetic VLF method proved to be useful in the Bükk Mountains. Mushrooms have not been applied to geological mapping before. Common species like Boletus edulis and Leccinum aurantiacum are correlated with siliciclastic and magmatic formations while Calocybe gambosa is correlated with limestone. The validity of this correlation observed in the eastern part of the Bükk Mts. was controlled on a site where there was an indicated (by the mushrooms only) but unexposed occurrence of siliciclastic rocks not mapped before. The extent and structure of this occurrence were explored with the VLF survey and a trial-and-error method was applied for the interpretation. This case study presented here demonstrates the effectiveness of the combination of these relatively simple and inexpensive methods.
