It is really hard to live today without having a personal vehicle to travel around. You would have different needs to meet every day and relying on the public transport system alone might not be a feasible option always. The automobile prices are quite high all the time and not everyone can afford to buy a new one in the current economy.

A study was conducted at the University of Agriculture, Makurdi, to determine water uptake at 6 and 12 hour intervals, and germination characteristics of scarified and non scarified seeds of castor bean accessions in 2008 and 2009. Two hundred seeds were selected from each accession: one hundred seeds were scarified mechanically by caruncle removal using knife (seed lot 1), one hundred seeds were not scarified (seed lot 2). Each seed lot was immersed in 10ml of distilled water contained in 9cm-diameter petridish. Thereafter, seed lots were weighed at every 6 h starting from 0 to 24 h, and at every 12 h up to 108 h.
In wireless sensor network nodes position estimation in space is known as localization. Node localization in wireless sensor network is important for many applications and to find the position with Received Signal Strength Indicator requires a number of anchor nodes. However the estimation of distance from signal strength decay in not very accurate especially in time varying environmental conditions and the estimation of exact direction required highly directive antenna but, may still affected by multipath fading. A Genetic Algorithm for wireless sensor network localization is proposed in this paper to solve the issue that the positioning accuracy is low with minimum anchor nodes. Hence in this paper we are presenting a Genetic algorithm for optimization approach which tries to find the optimal location by satisfying both the criteria with minimal error. The simulation results also shows effectively outperform both the techniques.
This paper is highlighting the trend of use of cloud computing. Cloud Computing gives range of computing resources like servers and storage of emails, documents, voice, etc. over the internet. It provides hosting environment which is instant, secure, scalable, flexible, and helps to save money, time and resources. Because of metaphor for the internet it’s called cloud computing where internet is cloud. In simplest words, cloud computing means keeping and retrieving data and programs over the Internet instead of our secondary memory of computer.This paper describing about the use of Cloud Computing in Organization, Advantage of Cloud Computing, Problems with Cloud Computing, Stack of Cloud Computing, Leaders of Cloud Computing and Future Forecast.
Having the hydropower potential of 42000 MW and other immense source of electrical energy, Nepal still faces the problem of load shedding. And this problem has catastrophic consequences as electricity rules the routine of our busy lives from micro to macro level; say to charge a cell phone (essence of today’s lives) or to fill tank by water for numerous purposes. However, the situation, when the daily busy schedule and the problem of load shedding intersect, can be addressed.
- This paper presents the concept of using a polyethene film to address the shortcomings of the conventional solar pond which are low efficiency, short operation time among others. The thermal behavior of a solar pond with a polyethene has been analyzed and compared with that without a polyethene film. The experiments show that: the heat storage layer (LCZ) temperature rising rate was significantly higher than that of single layer porous media solar pond. The polyethene film of thickness 100µm was used. The polyethene film brings about the greenhouse effect where the solar energy that penetrates the film is trapped and improves the efficiency of the storage zone. Results show that the efficiency of a polyethene stabilized pond rises to about 69 % compared to the conventional solar pond with about 52 %.
