Multirate systems are most commonly used in Digital Signal Processing (DSP). Systems that use more than one sampling rates in the digital signal processing are called multirate DSP. Multirate DSP consists of decimation and interpolation which are rate conversion techniques. Decimation reduces the sampling rate whereas interpolation increases the sampling rate of the signals. In this paper, some of the multirate signals processing techniques are discussed and FIR filter designs are implemented using different windowing techniques. The performances provided by those techniques are compared based on SNR, RMS, MSE, ENBW and correlation.

Steel braced frame is one of the structural systems used to resist earthquake loads in multi-storied buildings. Many existing reinforced concrete buildings need to retrofit to overcome the deficiencies to resist seismic loads. The use of steel bracing systems for strengthening or retrofitting seismically inadequate reinforced concrete frames is a viable solution for enhancing earthquake resistance. Bracing system reduces bending moments and shear forces in the columns. The lateral load is transferred to the foundation through axial action. Total weight of the existing structure will not change significantly after the application of the bracings. Steel bracing is economical, easy to erect, occupies less space and has flexibility to design for meeting the required strength and stiffness. The bracing system improves not only the lateral stiffness and strength capacity but also the displacement capacity of the structure. In the present study, the seismic performance of reinforced concrete (RC) buildings rehabilitated using concentric steel bracing is investigated. The bracing is provided for peripheral columns. A ten storey building is analyzed for seismic zone III as per IS 1893-2002 using ETABS 2015 Software. The models are retrofitted with various steel bracing systems on periphery columns storey-wise and analyzed for seismic forces. The building is analyzed for models with Diagonal bracing, ‘V’ type bracing, Inverted ‘V’ type bracing, Combined ‘V’ type bracing, ‘X’ type bracing, ‘K’ type bracing and compared with an un-braced frame. The effectiveness of various types of steel bracing in rehabilitating a ten storey building is examined. The effect of the distribution of the steel bracing along the height of the RC frame on the seismic performance of the rehabilitated building is studied. The main parameters in this study to compare the seismic analysis of buildings are lateral displacement, storey drift, axial forces in the columns, Base shear. The percentage reduction in lateral displacement is found out. It is found that the ‘X’ type of steel bracing significantly contributes to the structural stiffness and reduces the maximum storey drifts of the frames. The bracing systems improve not only the lateral stiffness but also the displacement capacity of the structure.

E-commerce is on the rise now and buying from E-commerce websites has become second nature to people. The ease of being able to compare different products and getting a general opinion of the product from user reviews has encouraged people to buy more products from E-commerce websites. Generally, a popular E-commerce website showcases thousands of products which gives a wide range of choice for the user. If a user needs to purchase a product, he/she would have to go through lot of reviews which can be time consuming. On an average, a product tends to have at least 50 reviews, and if the product is very popular, the review count ranges from 100 to 1000. – To make it easy for users to decide if the product is right for them or not, we have proposed a design methodology and built a tool to get the reviews of the products from which explicit features are extracted and analyzed. To do this, we use the Association Rule Mining (ARM) technique. Association rules are created by analyzing the review dataset and identifying frequent features. Using the criteria support and confidence we extract the frequent features. With the extracted frequent features, we classify the review sentences containing these features as positive or negative. Then the opinion words are extracted and classified either as positive or negative using a seed list which contains positive and negative words relevant to the product domain. With this system, the user need not go through thousands of reviews as our tool extracts the relevant review sentences containing the frequent features which are classified either as positive or negative for user viewing.

Wear is related to interactions between surfaces and specifically the removal and deformation of material on a surface as a result of mechanical action of the opposite surface. Wear of metals occurs by the plastic displacement of surface and near-surface material and by the detachment of particles that form wear debris. Brass is nowadays considered as one of the most important copper based alloys. In particular, up to date brass alloys have been extensively used in automotive hydraulic brake tubes, radiator tubes, carburetor, fasteners, journal bearings, construction and marine applications by virtue of their corrosion resistance in non-acidic environments, good mechanical properties, high thermal and electrical conductivity and low cost. In this experimental study, wear behavior of the brass (70% Copper-30% Zinc and some traces of impurities) pin is examined on Pin-on-Disc configuration, which is performed on wear and friction monitor machine. Influence of various parameters sliding speed (1-3m/s), contact distance (1000 m & 2000 m) and applied load (20 N, 30 N & 40 N) was examined. Output results indicated reduction in pin weight (gms) in dry and wet (lubricating) conditions. It was observed that the wear of all pins were significantly high at sliding distance of 2000 m and 3m/s speed compared to wear at sliding distance of 1000 m and 1m/s speed. Results showed that increased sliding distance and the sliding speed the wear were increased. Microscopic analysis of worn surfaces of various test samples indicated different wear patterns.

Digital multipliers are along with the majority critical arithmetic functional units. The general performance of the Digital multiplier systems depends on throughput of the multiplier. The negative bias temperature instability effect occurs when a pMOS transistor is under negative bias (Vgs = −Vdd), increasing the threshold voltage of a pMOS transistor and falling the multiplier speed. In the same way, positive bias temperature instability occurs when an nMOS transistor is under positive bias. Both effects degrade the speed of the transistor and in the long term, the system may be fail due to timing violations. For that reason, it is required to design reliable high-performance multipliers. In this paper, we implement an aging-aware multiplier design with a novel adaptive hold logic (AHL) circuit. The multiplier is able to provide the higher throughput through the variable latency and can adjust the adaptive hold logic (AHL) circuit to lessen performance degradation that is due to the aging effect. The proposed design can be applied to the column bypass multiplier. Additionally, the proposed design can be applied to a column- or row-bypassing multiplier. The experimental results show that our proposed design with 16bit and 32bit, 64bit column-bypassing multipliers.

Cloud storage is a storage service provide to user, where they can transfer their data anytime and any- where. With the great development of cloud computing in modern era, the massively increasing number of data, the chunk of information storage and the application requirement for high availability of data, network backup is facing an extraordinary challenge. On the other hand, a cloud server normally performs a data compression technique (data deduplication) to eliminate duplicate data because the storage is not infinite. Data deduplication, which makes possible for data holder to share a copy of the duplicate data, can be performed to reduce the consuming of storage space. Due to the issues, there is a some research on encrypted data deduplication. Data deduplication is one of fundamental data compression techniques for eliminating multiple copies of repeating data, and has been widely used in cloud storage to miniaturize the volume of storage space and bandwidth. Deduplication is storage optimization technique that avoids keeping duplicate copies of data. Presently, to provide security, data stored in cloud also other large storage areas are in an encrypted format and one issue with that is, we cannot apply deduplication over such an encrypted data. Thus, performing deduplication on the encrypted data in cloud surface to be a challenging task.

Shell and tube heat exchanger system is broadly utilized in chemical plants as it upholds broad range of temperature. Heat exchanger is generally employed to transmit heat from a hot liquid to a cooler liquid, so temperature control of exit liquid is having leading significance. To control the temperature of outlet fluid of shell and tube heat exchanger, a conventional PID controller can be used. Due to intrinsic demerits of conservative control techniques, variable structure control (VSC) based on sliding mode control (SMC) principle is proposed to control the temperature of the heat exchanger in this paper. Simulation results are presented and it is noted that, SMC control is better and more versatile as compared with the conventional approach using PID controller. Time domain specifications and ISE are used as performance measures.

This work attempts experimental studies in Tribological behaviour of aluminum silicon alloys. Aluminum alloys have extensive application in industries due to the better tribological properties. Mixing of silicon to aluminum tends to increase its strength to weight ratio and wear resistance, and tends to decrease its density and coefficient of thermal expansion. In the present work Al-Si alloy cylindrical pin is prepared from used pistons of IC Engines of automobile vehicles and experiments have done to determine the tribological behavior of aluminum-silicon 392.0 alloy sample pins (78%Al, 18%Si, 1%Mg, 1.07%Cu, 0.3%Fe). Experimental investigation has done using a pin on-disc type wear testing machine and selected testing parameters were sliding velocity, contact sliding distance and applied load. The final results indicated loss in pin weight (gms) in dry and wet (lubricating) conditions. And from the experiments, it has been observed that the wear of pin was significantly higher at sliding speed of 4m/s and sliding distance 4000m as compared to the lower sliding speed (2m/s) and distance (2000m). Results showed that with the addition of Silicon content, the hardness of alloys increases and by increasing sliding speed and sliding distance, wear rate also increases. The microscopic analysis, showed the different wear patterns at different loads and sliding speeds.

Heat is a form of energy that can be transferred from one system to another, as a result of temperature different. The transfer of energy as heat is always from higher temperature medium to the lower temperature. The science that deals with determinations of rates of energy transfer is HEAT TRANSFER. Heat transfer by convection between a surface and the fluid surrounding can be increase by attaching thin strips of metals to the surface called “FINS”. These are the extended surface used to increase the surface area. Fins are most commonly used in heat exchanging devices such as radiators in cars and heat exchangers in power plants. They are also used in newer technology such as hydrogen fuel cells. Nature has also taken advantage of the phenomena of fins. The ears of jackrabbits and Fennec Foxes act as fins to release heat from the blood that flows through them. In our project different cross-section of fins are used. For these fins the performance i.e. efficiency and effectiveness are calculated with both porous and non-porous media.

Due to the tremendous development in the field of web technology doors have opened for several e-commerce websites to market and sell products online. They also provide opportunity for the users to post opinions or reviews based on their experience in buying the products. So the trend has been set by buyers to go through reviews before buying any products and make decisions accordingly. But the main question that comes into picture is whether these reviews are believable or not. Nowadays due to review’s capacity to change buyer’s decision, there are people or firms whose only job is to write spam reviews either to falsely defame or to promote a product which is unethical. This paper mainly deals with a trust system through which the genuineness of the review is checked, which is based on the behavior of its reviewer towards other pre-fabricated reviews. Only those proved trustworthy can publish their reviews in the webpage so that those reviews are considered for opinion mining.
