Abstract

Sugarcane crop has been pride of Maharashtra state and plays a vital role in agricultural economy of the state. Maharashtra state had established enviable position in the Indian sugar industry by contributing 35 per cent of total sugar production (8.5 Million Tonnes of sugar). In spite of this in sugarcane crop system traditional methods of weeding and earthing up is labour as well as time consuming and cannot be done by tractor drawn implements because of restriction for their movement in sugarcane row as well as less land holding capacity of Indian formers. So that, the bullock drawn ridger and inter cultivators have got popularity in the major part of the country. Also all these operations in sugarcane crop are carried out using bullock drawn implements. Keeping above points in view the study was undertaken entitled, with view to fabricate and develop indigenous plough for ridging and inter-cultural operations for sugarcane crops. For the study the popular Kirloskar iron plough was selected as it is widely used in the region. This selected plough was developed such that it has furrowing and weeding tools with view to number of operations at a single pass of implement. It can also used for ridging, earthing up and weeding operation.The testing of developed indigenous plough was carried out in Kagal Tahsil of Kolhapur district for sugarcane crop by following RNAM standard test codes. The power required for ridging, earthing up and weeding operations was 0.91 hp, 1.26 hp and 1.38 hp, respectively. The effective field capacity was obtained about 0.18 ha/hr. 0.21 ha/hr. and 0.24 ha/hr. for ridging, earthing- up and weeding operations, respectively. The field efficiency of implement was obtained about 51.55 per cent, 56.58 per cent and 51.45 per cent for ridging, earthing up and weeding operations, respectively. The cost of operation of implement was obtained as 315.28 Rs./ha, 289.34 Rs./ha and 304.10 Rs./ha for ridging, earthing up and weeding operations, respectively. In this way newly developed indigenous plough had given better results especially for doing earthing up operation. Hence, the performance of newly developed indigenous plough was found satisfactory.

Abstract

The global issue of energy conservation demands the need of managing and coordinating power consumption. The current transients of various loads are unique, depending on application and some other parameters like load type. The "spectral envelope" representation of observed current and voltage signals used in the non-intrusive load monitoring can be a very flexible basis for computing and tracking all sorts of useful metrics about power consumption. With the help of spectral envelopes it is possible to estimate real and reactive power consumption and also harmonic contents. For power monitoring and energy scorekeeping, a FPGA (Field Programmable Gate Array) can be used to implement a Spectral Envelope Preprocessor to develop an inexpensive separate module for individual load to help precise monitoring of specific load.

Abstract

Jackfruit is a tropical large size exotic cylindrical-round shape fruit consists of bulbs (seed and carpel) and rind including mesocarp. Unripe and ripe jackfruits both have application in day to day use. Size, shape, volume and density of the components of the fruit as a whole and its components were determined. The unripe jackfruit average weight was in the range of 7-10 kg and average diameter was 32.35 cm and length was 40.4 cm which were reduced by about 20 per cent on ripening. Bulb, seed and rind components of ripe fruit were 47, 10 and 53 per cent, respectively. Volume of unripe jackfruit was 7.07 litres (7007 cc) and solid density and bulk density were 1005 kg/m³, 150.24 kg/m³, respectively. The weight for the unripe fruit bulb was 16.67 g and of ripe bulbs was 11.77 g. The volume of unripe fruit bulbs was 16.80 cm³ and that of ripe bulbs was 11.44 cm³. The bulk density of the unripe fruit bulbs were 809.59 kg/m³ and of ripe bulbs was 728.61 kg/m³. Seed of jackfruit weighed 3.88 g and volume and bulk density respectively was 3.51 cm³ and 854.28 kg/m³. Jackfruit was classified into three sizes based on length 28-34 cm as small, 35-45 as medium and more than 45 cm in length as large size fruits.

Abstract

India is experiencing tremendous growth in infrastructure including road network and highways. Roads are to be designed with good reliability to fulfill the long term performance during the design period. Long term performance of flexible pavement depends on the soundness of the underlying subgrade soil. Unstable, poor or weak soil can create significant problems for the pavement. Weak soil has low California bearing ratio (CBR) which will lead to more layer thicknesses of the pavement section. Considering an escalating cost of the aggregates, utilization of weak soil by imparting additional strength by way of stabilization technique is a need of time. Present research study insights on the evaluation of benefits of stabilization of subgrade soil. Two types of soil (Soil A and Soil B) having CBR of 1.45 and 4.67 and three types of stabilizers namely hydrated lime, class F fly ash and polypropylene fibre (aspect ratio of 100) were selected for the laboratory investigation. Experimental program consisting of Atterberg limit, compaction, california bearing ratio and unconfined compressive strength tests were carried out. These tests were performed on unstabilized as well as stabilized subgrade soil at different percentages of stabilizers by dry weight of soil. Percentage of lime varied from 1.5, 3.0, 4.5 and 6 %, for fly ash stabilization it was 5, 10, 15 and 20 % whereas percentage of fibre varied from 0.25, 0.50, 0.75 and 1 %. Results of laboratory investigation revealed that 4.5 % lime, 10 % fly ash and 0.5 % of fibre were optimum for the improvement of strength characteristics of subgrade soil stabilization.
