Abstract

This work concerns the comparative study between Hamming code and Reed-Solomon (RS) code in byte error detection and correction. Data are either stored in storage applications or transferred through a media. In either case there is problem of data corruption due to noise and interference, which has to be corrected as soon as they occur to prevent erroneous information throughout the system. The basis is to incorporate the original data with some form of redundancy. With this redundancy, even if errors are introduced, the original information can be recovered or at least the presence of error can be detected. Redundancy is added by the encoder and sent over the channel where noise in the form of error distorts the data. The message reaches the receiving end through the decoder where errors are removed, redundancy stripped off and the original message is then produced. This paper compared Hamming code and Reed-Solomon code in respect to their efficiency in adding and removing this redundancy. I find Reed-Solomon code to be highly efficient and more powerful than Hamming code for data communication because of it high coding rate and yet with a minimum coding complexity.

Keywords: Encoder and Decoder, Error detection and correction, Hamming code, Reed-Solomon code

Abstract

Sulfate attack is a complex form of deterioration that has damaged concrete structures throughout the world. Sulfate attack is particularly complex because the source of sulfates can be external or internal. The sulfate resistance of concretes containing different cement contents, water cement ratios, and C3A percentages is investigated in which concrete specimens were subjected to magnesium sulfate solution up to 450 days. Three cement contents as 350, 400, and 450 kg/m3 were used at different three water cement ratios (0.40, 0.50, 0.60) and three C3A percentages (4.24%, 6.87%, 10.84%). Concrete sulfate resistance was estimated based on measurement of four different mechanical properties; cube compressive strength, tensile strength, modulus of elasticity, and linear expansion strain. These mechanical properties were measured after different sulfate attack periods; 28, 60, 100, 200, and 350 days. Results of this study show that cement content increasing improved concrete sulfate resistance when the concrete is subjected to sulfate attack. Moreover, concrete with high water cement ratios, and C3A percentages showed low sulfate resistance. Concrete with low water cement ratios, and C3A percentages provides an good performance for sulfate resistance.

Performance Improvement of OFDM system and PAPR Reduction

Performance Improvement of OFDM system and PAPR Reduction

Abstract

One of the major concerns of Orthogonal Frequency Division Multiplexing (OFDM) systems are its high Peak to Average Power Ratio (PAPR) values. These high PAPR values result in serious degradation in performance when a nonlinear power amplifier is employed. The Conventional Partial Transmit Sequence (C-PTS) technique is one of the highly efficient methods for PAPR reduction in OFDM systems. Unfortunately, the number of Inverse Fast Fourier Transform (IFFT) operations employed in C-PTS technique is large and this adds to the computational complexity of the technique. In our proposed Hybrid technique, we have combined the C-PTS technique with predefined phase factor multiplication method. The peaks of the OFDM signal are compressed by making the out of phase sub blocks to in phase sub blocks. All the extra IFFT operations that are required for C-PTS technique are avoided by our proposed method. Signal clipping and filtering result in reducing PAPR values even further. The simulation results show that our proposed (post-phase optimized)PTS technique achieves better reduction compared to the Amplitude Clipping and Selective Level Mapping(SLM) technique at levels of reduced computational complexity.

Abstract

Industrialization has been fundamental to economic development. Not only is industrialization the normal route to development, but as a result of the globalization of industry, the pace of development can be explosive.(11) Many countries have reached higher development levels in all dimensions – economic, social and environmental – for the benefit of their people. Yet, steady prosperity has not been achieved throughout the world and there remain remarkable differences between and within regions, countries and societies. Growth in the past occurred too often without providing the opportunity of participation and reward to significant segments of the population, and women and youth in particular. Clearly, future strategies for poverty reduction need to be economically empowered. As a response to these challenges, is promoting inclusive and sustainable industrial development (5) .The industry views Sustainable Development as a challenge put before all parts of society. In the advances made in its own operations, its improved performance and in the improvements to the human condition made through its products, the industry sees cause for optimism and believes that Sustainable Development can be the intellectual framework around which industry and also sectors of society can reach consensus on how to improve living standards and the environment.

Abstract

The purpose of this study is to investigate the natural frequencies of a cantilever beam experimentally and validate the result with finite element analysis of the beam. The finite element analysis is performed in MATLAB programming and the output from the program is validated with the analysis of the beam in ANSYS. The free vibration response of the beam with lumped end mass subjected to an initial disturbance is also studied in this paper. Different end masses are attached at the free end of the beam to study the influences of these masses on the natural frequencies of the beam. The values of material parameters i.e. density and modulus of elasticity etc considered during experiment are measured experimentally in the testing lab. This experimental setup can be used to measure the natural frequencies of any cantilever beam whose material properties are unknown.

Abstract

Heat exchanger is a device which provides a flow of thermal energy between two or more fluids at different temperatures. There are many problems created in the segmental heat exchanger during and after the work. The major causes of this problem is the geometry of heat exchanger, type of fluid used, type of material etc., The purpose of this work is to design the shell and tube heat exchanger which is one among the majority type of liquid –to –liquid heat exchanger. Since the important design parameters such as the pitch ratio, tube length, and tube layer as well as baffle spacing has a direct effect on pressure drop and effectiveness, they are considered to be the key parameters in this work. General design consideration and design procedure are also illustrated in this work. The analysis of orifice baffle and convergent divergent tube in a shell and tube heat exchanger are experimentally carried out. The newly designed heat exchanger obtained a maximum heat transfer coefficient and a lower pressure drop. From the numerical experimentation, the result shows that the performance of heat exchanger increases in modified baffle and tube than the segmental baffle and tube arrangement.

Abstract

Consumers demand more from their technology. Whether it is a television, cellular phone, or refrigerator, the latest technology purchase must have new features. With the advent of the Internet, the most-wanted feature is better, faster access to information. Cellular subscribers pay extra on top of their basic bills for such features as instant messaging, stock quotes, and even Internet access right on their phones, E-mail, video calling. To support such a powerful system, we need pervasive, highspeed wireless connectivity. A number of technologies currently exist to provide users with high-speed digital wireless connectivity; Bluetooth, 802.11 and HIPERLAN are examples. These two standards provide very high-speed network connections over short distances, typically in the tens of meters. The goal is the same: long-range, high-speed wireless, which for the purposes of this report will be called 4G, for fourth-generation wireless system. Fourth-generation is characterized by new frequency bands, higher data rates and non backwards compatible transmission technology. The first release of the 3GPP Long Term Evolution (LTE) standard does not completely fulfill the ITU 4G requirements called IMT-Advanced. First release LTE is not backwards compatible with 3G, but is a pre-4G or 3.9G technology, however sometimes branded "4G" by the service providers. Its evolution LTE Advanced is a 4G technology. WiMAX is another technology verging on or marketed as 4G.

Abstract

In recent years, plastic surgery has become popular worldwide. People take facial plastic surgery to correct feature defects or improve attractiveness and confidence. It has been observed that many face recognition algorithms fail to recognize faces after plastic surgery, which thus poses a new challenge to automatic face recognition. Increasin g popularity of plastic surgery and its effect on automatic face recognition has attracted attention from the research community. Apart from cosmetic reasons, plastic surgery procedures are beneficial for patients suffering from several kinds of disorders caused due to excessive structural growth of facial features or skin tissues. These procedures amend the facial features and skin texture thereby providing a makeover in the appearance of face. This survey presents five papers that describe various methods used for surgically altered face image detection. Also discussed about the advantages and disadvantages of the papers.
