Solar power for Wireless Sensor Networks in  Environment Monitoring Applications-A Review

Routing in Wireless Sensor Networks has to take into account the limited battery resources of the nodes. Sensor nodes can also be powered by other energy sources like solar energy. This paper provides a review of Environment monitoring using Wireless Sensor Networks. The issues related to environment sensor networks is highlighted. The real time applications in environment monitoring is presented with emphasis on energy conservation. Furthermore in this paper we address the problem of scavenging energy using solar powered devices.

Analysis of structural features and classification of  Gujarati consonants for offline character rec

Wide range of applications and numerous other complexities involved in character recognition (CR) makes it a continuous and open area of research. Feature selection and classification plays major role in achieving higher accuracy for character recognition. In the era of digitization its compelling need to have CR system for regional script. This paper presents analysis of structural features and its classification for consonants of Gujarati script. Each character has certain characteristics which distinguishes it from other characters. Gujarati consonants are analyzed for eight such structural features and on the basis of it characters are categorized into twenty groups. Further Paper proposes decision table to classify characters based on structural features.

Studies to Improve Seed Germination in Tetraploids  Watermelon (Citrullus lanatus Thunb.)

Genetic improvement to produce seedless watermelon offers high quality fruits. This paper describes about problems related with tetraploid seed germination, various seed treatment to improve tetraploid seed germination and the morphological variations observed between the tetraploid and diploid seeds. Diploid watermelon seeds of three genetic backgrounds were treated with colchicine (0.2, 0.3 and 0.4%) and PEG (0.5%) as an adjuvent. Polyploid watermelon seeds have poor germination and low seedling vigor mainly due to thick seed coat and seed coat adherence to emerged cotyledons. In order to enhance the germination, the tetraploid seeds were subjected to five different seed treatments i.e; acid scarification, GA3 treatment, humidification, mechanical scarification and water soaking for 48hrs. Among the various treatments tested, maximum germination was recorded in the seeds subjected to water soaking for 48 hrs in all the three varieties.

Cost and Benefit Analysis of the adoption of Soil and  Water Conservation methods, Kenya

This paper assesses the net welfare associated with the adoption of Bench Terraces (BT), Contour Bunds (CB), and Napier Grass Strips (NGS) in the Saba Saba sub-catchment of the Upper Tana catchment in Kenya. An agro-economic survey and informal interviews were conducted in the Saba Saba sub-catchment to elicit farm level quantitative data for the Cost Benefit Analysis (CBA). Financial functions in excel were used to analyze the on-site costs and benefits of adopting the identified SWC technologies on farms with crops such as maize, coffee, and tea. In this research CBA was used as a decision tool after the computation of all cost and benefits were valued in local currency to obtain the Net Present Value (NPV) or net welfare. The results show that investment in SWC measures may not be a feasible short-term option from farmers’ perspective. There is, therefore, a strong case for intervention, especially in the initial years where SWC adoption yields negative returns.

Design of 32Bit Carry-lookahead Adder using  Constant Delay Logic

This paper presents an enhanced 32-bit carry lookahead(CLA) adder implementing using the constant delay (CD) logic, targeting at full-custom high-speed applications. The CD characteristic of this logic style regardless of the logic type makes it suitable in implementing complicated logic expressions such as addition. CD logic exhibits a unique characteristic where the output is pre-evaluated before the inputs from the preceding stage is ready. This feature offers performance advantage over static and dynamic domino logic styles in a single-cycle multistage circuit block. Several design considerations including timing window width adjustment and clock distribution are discussed. Using 65-nm general-purpose CMOS technology, the proposed logic demonstrates an average speed up of 94% and 56% over static and dynamic domino logic, respectively, in five different logic gates. Simulation results of 8-bit ripple carry adders show that CD logic is 39% and 23% faster than

Review on Basic Clustering Techniques for  Heterogeneous Wireless Sensor Networks

Clustering technique is the basic technique used in the wireless sensor network to enhance the lifetime of a sensor network by mitigating energy consumption and provide efficiency, scalability, and security. Formerly sensor nodes are considered to be homogeneous in which each node has the same processing capacity, energy and functionality, but to prolong network lifetime researches has been evolved to infuse heterogeneity in wireless sensor network such as to provide different energy level to some nodes. In this paper, we present a survey on basic clustering techniques for Heterogeneous wireless sensor networks.

RF and Microwave Oscillator Design using p-HEMT  Transistor

This paper presents a systematic approach to designing negative-resistance and Colpitts oscillators using p-HEMT transistor. Various models such as, common source and common gate configuration in negative-resistance oscillators, common source series feedback in Colpitts oscillator is selected to analyze the output power and stability presented by the p-HEMT transistor. These oscillators are designed at 2.45 GHz frequency for which we find application in Bluetooth and Wi-Fi. In this paper, these designs are studied and tested, with their results analyzed below. Further, study proved that the Colpitts oscillator designed gave more output power and stability than the negativeresistance oscillators
