Speed control of Direct Current motor using Artificial Neural Network

Direct current motors (DC Motors) are widely used in many industrial applications and traction due to its straight forward and comparatively easy speed control ability. The purpose of this paper is to implement a speed control mechanism using artificial neural network (ANN) to achieve accurate control of the speed, especially when the motor and load parameters are unknown.

The role of Metropolitan Iakovos in Albanian-Greek  relations (1919-1921)

This paper examines the role that Greek Metropolitan Iakovos played in Albanian-Greek relations from the end of World War I to the establishment of a national Autocephalous Orthodox Albanian Church in 1922. As a result of the political and social structure that was in place during the Ottoman Empire, religion played a significant role in postOttoman politics.

Spatial distribution of the pit builders antlion’s larvae  (Neuroptera: Myrmeleontidae) in the septe

Antlions (Insecta: Neuroptera) are xerophilous insects adapt to arid conditions that perform some resilent behaviours to overcome some noxious effects of the global warming. This paper focuses on the determination of the diversity of the antlion in the Soudano-guinean and Soudano-sahelian area of Cameroon analyzes the distribution of antlion larvae in these regions. After 3 years of survey, 3 antlions species dominate in the North of Cameroon especially in the dry season. Pits distribution under four tropical trees species is irregular, there is higher density of pits close to the trunck at the shade. This decreases from the shade to open space. At the regional level, the antlion’s pit site is influenced by the chemical composition of the soil: higher acidity, salinity, calcium and magnesium content are suppressive to larval development in one hand.

 Genetic Algorithm for Wireless Sensor Network With Localization Based Techniques

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.

Cloud Computing an Emerging Technology to Save  Money, Time and Resources

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.

Comparison of Thermal Storage Efficiency of Solar Pond  with and without a Polyethene Membrane.

- 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 %.

Block-Based Neural Network for Automatic Number  Plate Recognition

Automatic Number Plate Recognition (ANPR) system is highly accuracy-demanded application for car identification. This paper presents a new method of block-based ANPR system for recognition of Indian car license number plates. Since number plate guidelines are not strictly practiced in India and wide variations found on these plates in terms of font type, character size, screws/dots etc., it often becomes difficult to correctly identify the non-standard number plate characters. This proposed method works well with both standard and nonstandard Indian number plate images taken under various illumination conditions. By using the block-based feature extraction process this method of recognition provides a high recognition rate of 98.2% and speed up the processing time of each character to 3.3ms when using a database of 3399 character images.

Enhancing Performance Mesh Networks by Utilizing  Excess Capacity

Wireless mesh networks (WMNs) have gained considerable interest in expanding IEEE 802.11 networks to large-scale enterprise and community scenarios, primarily because of its capability of providing wide-band network access to a significant number of users. However, the mesh nodes are typically limited in resources such as bandwidth, computation power and memory. Capacity limitation is one of the fundamental issues in wireless networks. Excess capacity(EC) is the unused capacity. Here in this paper EC Management techniques are used to improve network performance.
