Evaluating the Enhancing Capacity of Multiple Carrier  Code Division Multiple Access (Mc-Cdma) Syste

In Communication system, the system capacity and performance are adversely affected and degraded by interference. Hence, power control plays a prominent role in an interference-limited system, which increases the efficiency by mitigating the adjacent and co-Channel interference in the system. In this paper, primarily power control is said to be used in maintaining the acceptable Carrier to Interference Ratio (CIR) by meeting some Quality of service (QoS) requirements Objective function that is defined as maximum channel capacity in a power constraint scenario. The signals in a radio channel undergo different propagation effects like reflection, refraction, scattering and shadowing. Hence, the distribution of users across subcarrier groups as well as their transmission powers within a given cell has a significant effect on how users and power are accordingly distributed elsewhere in the network to maximize the capacity of the system thereby enhancing its performance

Material Selection for Computer Aided Design Software  for Crankshaft Design

A crankshaft contains two or more centrally-located coaxial cylindrical ("main") journals and one or more offset cylindrical crankpin ("rod") journals. The design of the Crankshaft considers the dynamic loading and the optimization an lead to a shaft diameter satisfying the requirements of Automobile’s specifications with cost and size effectiveness. Microsoft visual studio package was used in the development of this software, which is capable of designing the shaft with reference to its easy interface, being an open system and its ease of file formats acceptability. It was used during the entire cycle of this software development (analysis phase, design phase and implementation phase).

Proximate and Mineral composition of Some Traditional  Vegetables in Akwa Ibom State, Nigeria.

This research work was carried out to investigate the proximate and mineral composition of some traditional vegetables in Akwa Ibom State, Nigeria. These vegetables include: Talinum triangulare, Hensia crinita, Cucurbita maxima and Lasianthera africana. The vegetables were washed in potable water to remove unwanted matters and were analyzed for proximate and mineral content. All analyses were carried out in three replicates and the mean data were presented on tables using the spread sheet Microsoft Excel. Talinum triangulare had the highest protein content (56.72%) and moisture content (80.11%) but had the lowest content of ash (6.31%), crude fibre (2.96%) and carbohydrate (6.91%). Ash and crude fibre were present in low quantities in Talinum triangulare, Hensia crinita, and Lasianthera africana, except Cucurbita maxima which had the highest composition of ash (14.06%) and crude fibre (9.37%). Mineral composition (Potassium (K), Calcium (Ca), Magnesium (Mg) and

An Improved VCO Design with Negative Feedback to  Reduce Jitter at High Frequencies

This paper presents an improved design of voltage controlled oscillator (VCO) utilizing the three differential cell CMOS inverters for forming the ring oscillator. The differential cell reduces the power supply fluctuations impact on the oscillator jitter while the negative feedback from frequency to voltage converter reduces the jitter at high frequencies. Finally the proposed model is designed using CMOS 0.18um foundry technology and simulated using P-Spice software. The result shows that the proposed design improves the jitter attenuation at different offset frequencies up to 40dB

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.

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

Efficient Majority Logic Fault Detection in Memory  Applications with Difference-Set Codes

Even a small transition delays and little faults create major concern in digital circuits. It Produce greater impact on not only for simple memory but also for most of the memory applications. This paper presents an error-detection method for difference-set cyclic codes with majority logic decoding. Majority logic decodable codes are suitable for memory applications due to their capability to correct a large number of errors. However, they require a large decoding time that impacts memory performance. The proposed fault-detection method significantly reduces memory access time when there is no error in the data read. The technique uses the majority logic decoder itself to detect failures, which makes the area overhead minimal and keeps the extra power consumption low. The proposed method detects the occurrences of single error, double error ,triple error in the received code words obtained from the memory system.

Development of Maintenance Strategy to Improve  Performance of Natural Draft Cooling Tower

Cooling tower is an important part of power plant. The efficiency of power plant is directly depends on the effectiveness of cooling tower. In cooling tower scheduled maintenance and shutdown maintenance is a problem which affects its effectiveness and performance of cooling tower. In cooling tower shutdown maintenance required in every 2 to 3 year periods at this period the whole plant will be shutdown, and require 28 to 35 days maintenance so that cooling tower will be in its best working condition. In every cooling tower manufacturer provide the scheduled maintenance check list so that the worker will perform their maintenance as per given instruction. In present work optimization of shutdown maintenance strategy is done so that the time elapsed in maintenance will reduce and the requirement of man power will be reduced.
