A soil moisture sensor is an integral aspect of the various precise irrigation techniques. This paper focuses on a BJT based soil moisture sensor which can be implemented in a large array spreading throughout an irrigated field. Soil conductivity depends on the moisture content around the probes. This is particularly useful for monitoring moisture levels around roots of crops planted in an organized manner. The network architecture allows real time monitoring. A microcontroller is used to scan the array of sensors for output values by operating a switch IC, to calculate the moisture percentage value corresponding to the voltage output of each sensor, to display the percentage moisture value or to operate the valves in drip irrigation or sprinkler systems. The whole architecture is easy to implement and cost-effective. The paper also shows the results of the experiments conducted using this sensor to highlight the effect of the potash and urea fertilizers on the soil properties.

Buns are basically small sized wheat based bread, which are very popular due to its small shape and complete consumption at one time. The buns are generally used as burgers and other fast food items. The buns do not possess a good quantity of vitamins and dietary fiber. Hence, studies were conducted to develop carrot pomace and fine wheat flour based buns. Product development was done by conventional method utilizing carrot pomace in the different proportions of (0, 2.5, 5, 7.5 and 10%). All the ingredients were mixed to obtain good consistency dough, later on these were baked in hot air-oven at 177±20C for up to 40 minutes to a golden brown Colour. It was observed that the expansion, water solubility and absorption index decreased with the increase in pomace proportion, whereas bulk density and moisture content increased with the increase in pomace proportion. It was further noted that the expansion, water solubility and absorption index and bulk density were having significant correlation to the pomace proportion (p<0.05). The buns prepared with carrot pomace at 2.5% levels, showed a very good result in sensory evaluation. The product was recommended for production of carrot buns.

Steganography is defined as the science or even possibly art of hiding likely critical information within other, seemingly benign information. The point of steganography is to prevent the detection of information leakage, not encrypt data. However, there is nothing stopping a user, malicious or otherwise from first encrypting a secret message and then embedding it inside harmless information. The process only deals with embedding one bit stream (the hidden information) inside of another bit stream. Either bit stream can be of any form. However, steganography is frequently used in conjunction with cryptography. In one method, the plain-text would first be encrypted and then feed to the steganography program. This ensures that if the hidden message is retrieved, the plain-text will still be encrypted. The reverse procedure also works. Two technologies that are closely related to steganography are watermarking and fingerprinting. These technologies are mainly concerned with the protection of intellectual property, thus the algorithms have different requirements than steganography. In watermarking all of the instances of an object are “marked” in the same way. The kind of information hidden in objects when using watermarking is usually a signature to signify origin or ownership for the purpose of copyright protection. With fingerprinting on the other hand, different, unique marks are embedded in distinct copies of the carrier object that are supplied to different customers. This enables the intellectual property owner to identify customers who break their licensing agreement by supplying the property to third parties.

Rainfall data of 20 years (1982-2001) based on standard weeks was analyzed for Bilaspur District of Chattisgarh State. The earliest dates of monsoon periods were determined along with their deviations from the mean value. The frequency of dry and wet weeks was calculated by using the concept developed by Pandarinath by considering 20mm rainfall in a week as a demarcation line. Dry and wet spells in pre monsoon, monsoon, and post monsoon periods were estimated by using Markov Chain Model. The monthly maximum rainfall at different probability levels was calculated by using Gumble Probability Method. It was observed that there were 23 dry weeks in pre monsoon and 19 wet spells in monsoon at 0.75 probability density, which was found in close proximity with the observed rainfall for the year 2001. The estimation of deficit periods showed that there was a need of irrigation water especially in the 20th to 23rd weeks and 30th to 33rd weeks after transplanting of paddy crop. Moisture deficit periods were calculated by comparing the mean monthly evapo-transpiration values with the mean monthly rainfall values of Chhattisgarh.

Continues growth of electrical energy demand is resulting in a corresponding increase in the short circuit in power system, which results in voltage sag problems and threat to power quality in the system. Several solutions have been implemented, including the use of Fault Current Limiter (FCL), in order to reduce circuit breakers rated capacity and to limit the electromagnetic stress in associated equipment. This paper presents a study of the impact of fault current limiter in power system performance and hence improving the power quality. In order to evaluate the impact of fault current limiter in power system performance, simulation models of power system performance with ‘FCL’ are used. For simulation model development, MATLAB simulation tool “SIMULINK” software is used. A distribution system fed from single source is used to assess the impact of ‘FCL’ to power system performance.

Computer software has progressively turned out to be an essential component in modern technologies. Testability is the probability whether tests will detect a fault, given that a fault in the program exists. How efficiently the faults will be uncovered depends upon the testability of the software. Various researchers have proposed qualitative and quantitative techniques to improve and measure the testability of software. Furthermore, it is well known fact that the progress of software testing is influenced by various uncertainty factors like effort expenditure, skill of test personal, testing tool, defect density and irregular state of software fault-report phenomena on the bug tracking system. Hence, there is an irregular fluctuation in fault detection/removal rate during testing phase. In this paper, distribution based software reliability growth models have been developed by applying Itô type Stochastic Differential Equations in order to incorporate (i) the irregular fluctuation in the fault detection process due to various uncertainty factor during testing phase; (ii) two types of imperfect debugging and (iii) change-point concept. The proposed stochastic differential equation based models have been validated using real data sets. Various comparison criteria results for goodness of fit have also been presented in the paper.

In this work we studied the optical properties of Poly [2-methoxy-5-(2’-ethylhexyloxy)-p-phenylene vinylene] (MEH-PPV) using polymeric blends with polystyrene. The photoluminescence spectrum of (MEH-PPV) present three characteristic peaks correlating to aggregate electronic transition at 608, 674 and 742 nm at 10° K. An addition of Polystyrene in MEH-PPV films induces a red shift in the absorption spectrum and the photoluminescence spectrum presents a new peak at high energy centred at about 572 nm at 10° K. It is attributed to intra band transition between localized intraband states.

The software industry can be considered as the typical high technology industry where rate of innovation and knowledge creation plays a pivotal role for continued firm growth. In the last few decades it has been observed that the world of software development management has evolved rapidly due to the intensified market competition. In particular the use of feature-addition model of software products in the industry is fast becoming the commonplace. The up-gradation model can be characterized by increasing the number of features in the software that will give the firm competitive edge in the market. The up-gradation of the system is done by extending it through add-ons, interfacing with other applications etc. Continuous up-gradation of software’s also brings complexity in the systems once it failed to work properly. In recent years, there has been a growing interest to predict the link between the rates of failure and the reliability of software. Many software reliability growth models (SRGMs) have been proposed over past three decades that estimate the reliability of a software system as it undergoes changes through the removal of failure causing faults. But unfortunately most of the models didn’t consider anything about the increase in failure rate once an up-gradation is made on the software. The objective of this paper is to propose the software reliability growth model that incorporates the effect of enhancement of features on software during testing and debugging process. Results have been supplemented with numerical examples.
