Optimum Crop Productivity in Rain Fed Area of Thana Boula Khan, Sindh, by Application of Wind Energy
Optimum Crop Productivity in Rain Fed Area of Thana Boula Khan, Sindh, by Application of Wind Energy
Abstract: The energy and food security are crisis at global level. Various sources for generating energy are under exploitation but except of renewable energy are almost costly. Hence, proper exploration and exploitation renewable energy is cheaper in comparison of fossil fuels source. In this connection, wind energy source mostly is available in the southern region of Sindh province of Pakistan. Renewable energy and agricultural farming are a winning combination. Wind, solar, and biomass energy can be harvested forever, providing farmers with a long-term source of income. The net farm returns can significantly be enhanced if available stronger winds are effectively utilized as an alternative energy resource. The project has successfully been introduced by locally manufactured windmill driven pumping units. The wind speed probability analysis based upon limited data availability indicated that during almost 92% of operational time, a wind speed of 2.5 m/s (9 km/hr) or more was available in project area. The operational analysis of windmill during 2007 indicated average 9.38 liter/min discharge was extracted, with role of 95.5 m3 of water was pumped in Kharif season, which is sufficient to irrigate 0.096 hectare of land through surface irrigation method by maintaining 10 cm depth of applied water. However, modern and efficient irrigation methods like drip and sprinkler be employed alongside windmill introduction for getting optimum agricultural productivity.

Mitigation of Power Quality Issues by Nine Switches UPQC Using PI & ANN with Hysteresis Control
Mitigation of Power Quality Issues by Nine Switches UPQC Using PI & ANN with Hysteresis Control
Abstract: A nine-switch power converter having two sets of output terminals was recently proposed in place of the traditional back-to-back power converter that uses 12 switches in total. The nine-switch converter has already been proven to have certain advantages, in addition to its component saving topological feature. Despite these advantages, the nine-switch converter has so far found limited applications due to its many perceived performance tradeoffs like requiring an oversized dc-link capacitor, limited amplitude sharing, and constrained phase shift between its two sets of output terminals. Instead of accepting these tradeoffs as limitations, a nine-switch power conditioner is proposed here that virtually ―converts‖ most of these topological short comings into interesting performance advantages. Aiming further to reduce its switching losses, Harmonics, Voltage Sag & Swell an appropriate discontinuous modulation scheme is proposed and studied here in detail to doubly ensure that maximal reduction of commutations is achieved. With an appropriately designed control scheme with PI and ANN with Hysteresis controller then incorporated, the nine-switch converter is shown to favorably raise the overall power quality in Simulation, hence justifying its role as a power conditioner at a reduced cost.
Index Terms: Discontinuous pulse-width modulation, nine switch converter, power conditioner, power quality.

Modeling of RF Power Amplifier with Memory Effects using Memory Polynomial
Modeling of RF Power Amplifier with Memory Effects using Memory Polynomial
Abstract: Power Amplifier is one of the most important component in a communication system. It is inherently non-linear and having memory effects. But current communication systems require highly linear response as nonlinearities contribute to gain compression and produce harmonic distortion. But for linearization of power amplifier, it is necessary to model PA's memory behavior accurately. So in this paper, a memory polynomial based power amplifier model is presented which takes into account its memory effects for wideband applications. This paper also presents a comparison of proposed model with actual RF power amplifier in terms of power spectral density and AM/AM characteristics. Simulation results shows its efficiency and accuracy.
Key words: AM/AM characteristics, MATLAB, Memory Effects, Memory polynomial, Power Amplifier (PA).

A Tool to Search and Convert Reduplicate Words from Hindi to Punjabi
A Tool to Search and Convert Reduplicate Words from Hindi to Punjabi
Introduction: Language, the best means of communication, is not a static one. It changes from time to time. The causes for these changes may be borrowing, language contact and interference and convergence from other languages. Due to these processes many structural features may come from one language into another Language. These exchanges reflect in the phonological, morphological and lexical levels. While working with the various kind of languages there are some circumstances when there is reduplication of words that is repetition of all or the part of the word. Reduplication, the doubling or partial doubling of syllables and words, is very frequent in Hindi-Urdu. It may apply to full words of any kind: nouns, adjectives, adverbs, verbs (but not auxiliary verbs), even pronouns:

Design and Analysis of New Modified Feedthrough Logic (MFTL) Circuits Using Carbon Nanotube Field Effect Transistor (CNTFET)
Design and Analysis of New Modified Feedthrough Logic (MFTL) Circuits Using Carbon Nanotube Field Effect Transistor (CNTFET)
Abstract: It is a challenging task for a VLSI design engineer to develop low power VLSI circuits, without sacrificing its performance. Feedthrough Logic (FTL) is a new technology which could be considered better than the existing technologies for improving circuit efficiency. Modified Feedthrough Logic (MFTL), offers a better power factor than the FTL logic structures, and also shows an improvement in the speed factor. But the scenario again changes when the design extends to nano scales of device dimension, where many factors which were neglected otherwise need to be given more importance. To avoid or minimize problems like hot carrier effects, electro migration, drain induced barrier lowering and other issues that becomes prominent in nano scale MOSFET‟s, Carbon Nanotube Field Effect Transistor (CNTFET) is considered to be a promising candidate in future integrated circuits. Hence this work extends the advantages of MFTL logic into nano level by incorporating CNTFETs in place of MOSFETs. The modifications have been implemented using CNTFETs of 16nm technology from HSPICE library on a 10 chain inverter stage, an 8 bit RCA and a Vedic multiplier and performance factors like PDP and ADP are compared to that of the conventional MOSFET circuits.
Key words: CNT, Domino logic, FTL, MFTL

OFDM PAPR Reduction Using Hybrid Partial Transmit Sequences Based On Cuckoo Search Algorithm
OFDM PAPR Reduction Using Hybrid Partial Transmit Sequences Based On Cuckoo Search Algorithm
Abstract: The past decade has seen many radical changes and achievements in the field of wireless communication. Applications of wireless communication have grown swiftly in the recent past. This rigorous growth leads to more throughput over wireless channels along with increased reliability. But still the bandwidth demands are endless and increasing day by day. Today we need to constantly work towards achieving reliable wireless communication with high spectral efficiency, low complexity and good error performance results. Orthogonal frequency division multiplexing (OFDM) technique is a promising technique in this regard as it offers high data rate and reliable communications over various fading channels. But the main drawback of OFDM is the high peak to average power ratio (PAPR). In this paper we present the technique to reduce the PAPR using Cuckoo Search Algorithm in multicarrier modulation system. Simulation results show that the proposed scheme considerably outperforms the conventional system.

Comparative Analysis of Lossless Image Compression Based On Row By Row Classifier and Various Encoding Schemes on Color Images
Comparative Analysis of Lossless Image Compression Based On Row By Row Classifier and Various Encoding Schemes on Color Images
Abstract: Lossless image compression is needed in many fields like medical imaging, telemetry, geophysics, remote sensing and other applications, which require exact replica of original image and loss of information is not tolerable. In this paper, a near lossless image compression algorithm based on row by row classifier with encoding schemes like Lempel Ziv Welch (LZW), Huffman and Run Length Encoding (RLE) on color images is proposed. The algorithm divides the image into three parts R, G and B, apply row by row classification on each part and result of this classification is records in the mask image. After classification the image data is decomposed into two sequences each for R, G and B and mask image is hidden in them. These sequences are encoded using different encoding schemes like LZW, Huffman and RLE. An exhaustive comparative analysis is performed to evaluate these techniques, which reveals that the proposed algorithm have smaller bits per pixel (bpp) than simple LZW, Huffman and RLE encoding techniques.

Utilization of Industrial Waste Material in GSB Layer
Utilization of Industrial Waste Material in GSB Layer
Abstract: India has series of steel plant clusters located along its length and breadth of the territory. Several million metric tons of iron and steel are produced in these plants annually. Along with the production of iron and steel, huge quantities of solid wastes like blast furnace slag and steel slag as well as other wastes such as flue dust, blast furnace sludge, and refractories are also being produced in these plants. These solid wastes can be used as non-traditional/non-conventional aggregates in pavement construction due to acute scarcity of traditional/conventional road construction materials. A study was conducted to investigate the possibility of using Granulated Blast Furnace Slag (GBFS) with various blended mixes of traditional/conventional aggregates in subbase layer with different percentages. This study also presents the result of experimental investigation on the influence of Rice husk ash (RHA) on the index properties of Red soil which is used as filler material in subbase layer.
Key words: California bearing ratio (CBR), Granular Subbase (GSB), granulated blast furnace slag (GBFS), Rice husk ash (RHA).

Geometry of model is created and meshed by using ANSYS Workbench software. To solve the equation for the fluid flow and heat transfer analysis ANSYS FLUENT was used in the fin-tube heat exchanger. The fluid flow and heat transfer are simulated and result compared for both laminar and turbulent flow models k-epsilon and SST k-omega, with steady state solvers to calculate heat transfer, flow velocity and temperature fields of variable inclined fin angles (Ɵ = 00,100 , 200, 300, 400,500). Model is validate by comparing the simulated value of velocity, temperature and colburn factor with experimental and numerical results investigated by WANG [1] and GHORI KIRAR [10]. Reasonable agreement is found between the simulations and other results, and the ANSYS Fluent software is sufficient for simulating the flow fields in tube fin heat exchanger.
Key words: Plate fin Heat Exchanger, Computational Fluid Dynamics(CFD), ANSYS Work Bench, FLUENT.

A Review: Compensation of Mismatches in Time Interleaved Analog to Digital Converters
A Review: Compensation of Mismatches in Time Interleaved Analog to Digital Converters
Abstract: The execution of today's correspondence frameworks is exceedingly subject to the utilized Analog-to-Digital converters (ADCs), and with a specific end goal to give more flexibility and exactness to the developing correspondence innovations, superior-ADCs are needed. In this respect, the time-interleaved operation of an exhibit of ADCs (TI-ADC) might be a sensible result. A TI-ADC can build its throughput by utilizing M channel ADCs or sub converters in parallel and examining the data motion in a period-interleaved way. In any case, the execution of a TI-ADC gravely suffers from the bungles around the channel ADCs. In this paper we survey the advancement in the configuration of low-intricacy advanced remedy structures and calculations for time-interleaved ADCs in the course of the most recent five years. We devise a discrete-time model, state the outline issue, and finally infer the calculations and structures. Specifically, we examine proficient calculations to outline time-differing remedy filters and additionally iterative structures using polynomial based filters. Thusly, the remuneration structure may be utilized to repay time-differing recurrence reaction befuddles in time-interleaved ADCs, and in addition to remake uniform examples from nonuniformly tested indicators. We examine the recompense structure, research its execution, and exhibit requisition zones of the structure through various illustrations. At long last, we give a standpoint to future examination questions.
Index Terms: Analog-to-digital converter, compensation, frequency response mismatches, reconstruction, time-inter- leaved, time-varying filter.

Performance Analysis of a Shell Tube Condenser for a Model Organic Rankine Cycle for Use in Geothermal Power Plant
Performance Analysis of a Shell Tube Condenser for a Model Organic Rankine Cycle for Use in Geothermal Power Plant
Abstract: The global energy demand increases with the economic growth and population rise. Most electrical power is currently generated by conventional methods from fossil fuels. Despite the high energy demand, the conventional energy resources such as fossil fuels have been declining. In addition to this harmful combustion byproducts are resulting global warming. However, the increase of environmental concerns and energy crisis can be minimized by sustainable utilization of the low to medium temperature heat resources. The Organic Rankine Cycle power plant is a very effective option for utilization of low grade heat sources for power generation. Heat exchangers are the main components of the Organic Rankine Cycle power plant which receives heat energy from the heat source to evaporate and condense the low boiling temperature organic working fluid which in turn drives the turbine to generate power. This paper presents a simplified approach to the design, fabrication and performance assessment of a shell tube heat exchanger designed for condenser in a model Organic Rankine Cycle geothermal power plant. The design involved sizing of heat exchanger (condenser) using the LMTD method based on an expected heat transfer rate. The heat exchanger of the model power plant was tested in which hot water simulated geothermal brine. The results of the experiment indicated that the heat exchanger is thermally suitable for the condenser of the model power plant.

Experimental Study on Performance of Concrete M30 with Partial Replacement of Coarse Aggregate with Sea Shells and Coconut Shells
Experimental Study on Performance of Concrete M30 with Partial Replacement of Coarse Aggregate with Sea Shells and Coconut Shells
Abstract: In this research work experiments have been conducted with collection of materials required and the data required for mix design are obtained by sieve analysis and specific gravity test. Sieve analysis is carried out from various fine aggregates (FA) and coarse aggregates (CA) samples and the sample which suits the requirement is selected. Specific gravity tests are carried out for fine and coarse aggregate. The various materials used were tested as per Indian standard specifications. On the basis of the experimental studies carried out on M30 grade concrete as partial replacement of coarse aggregates with sea shells and coconut shells, the following conclusions are drawn from the above experiment we conclude that comparing to traditional concrete, compressive strength of 10% (5% + 5%) of coconut shells (5%) and sea shells (5%) increased. whereas the compressive strength of the concrete cubes has gradually decreased from addition of 10% (5% + 5%) of coconut shells and sea shells. Hence for economical view 10% is preferable and in the perspective of compressive strength 10% is suggested. Thus, 10% replacement coconut shells and sea shells are recommended for both heavy weight and light weight concrete production.

A Multi-Objective Fuzzy Linear Programming Model for Cash Flow Management
A Multi-Objective Fuzzy Linear Programming Model for Cash Flow Management
Abstract: Although significant research work has been conducted on cash flow forecast, planning, and management, the objective is constantly the maximization of profit/final cash balance, or minimization of total project cost. This paper presents a multi-objective fuzzy linear programming model (FLP) for resolving the optimization problem of three conflicting objectives: final cash balance, cost of money, and initial cash balance. The proposed model depends on Jiang et al. (2011) Model. In the new formulation, both the advanced payment and delay of owner's progress payment one period were considered. Literature concerned with cash flow studies and models for construction projects was reviewed. Fuzzy linear programming applications in literature was presented and it's concept was then described. Jiang et al. (2011) Model is presented. The proposed model development was then presented. The proposed model was validated using an example project. An optimization of each individual objective was performed with a linear programming (LP) software (Lindo) that gave the upper and lower bounds for the multi-objective analysis. Fuzzy linear programming was then applied to optimize the solution. Four cases are considered: considering advanced payment and delay of owner's progress payment one period simultaneously, then separately, and neglecting advanced payment and delay of owner's progress payment. Penalty of delayed payment have been also considered. Analysis of the results revealed that the model is an effective decision making tool to be used by industry practitioners with reasonable accuracy.
Key words: fuzzy linear programming; final cash balance; cost of money; initial cash balance; advanced payment; delay of payment.

OPERATION & CONTROL OF SMART GRID CONNECTED PV- FC HYBRID POWER SYSTEMD
OPERATION & CONTROL OF SMART GRID CONNECTED PV- FC HYBRID POWER SYSTEMD
Abstract: This paper presents a method to operate and control a grid connected hybrid power system. The hybrid system composed of a Photovoltaic (PV) array and a Proton exchange membrane fuel cell (PEMFC) is considered. The PV array normally uses a maximum power point tracking (MPPT) technique to continuously deliver the highest power to the load when variations in irradiation and temperature occur, which make it become an uncontrollable source. In coordination with PEMFC, the hybrid system output power becomes controllable. Two operation modes, the unit-power control (UPC) mode and the feeder-flow control (FFC) mode, can be applied to the hybrid system. The coordination of two control modes, the coordination of the PV array and the PEMFC in the hybrid system, and the determination of reference parameters are presented. The proposed operating strategy with a flexible operation mode change always operates the PV array at maximum output power and the PEMFC in its high efficiency performance band, thus improving the performance of system operation, enhancing system stability, and decreasing the number of operating mode changes

Design and Implementation of Digital PLL using Self Correcting DCO System
Design and Implementation of Digital PLL using Self Correcting DCO System
Abstract: The mainstay of the paper is to use a PLL using self healing pre-scalar. When a CMOS technology approaches to a nanometer scale, the non-idealities like variability and leakage current may affect the circuit performances. The process variability leads to the large variations to degrade the device matching and performances. The leakage current is highly dependent upon the process variations. In the existing method the key parameter is to be change the modulus value of the pre- scalar. By changing the value of the pre-scalar the PLL frequency range will be extended. In the proposed design we are planning to implement the digital PLL technique with self correcting DCO. The structure utilizes the DDR synthesizer as a base for generating the DCO frequency, so many methods are there to correct the DCO errors , here we detect the error or delay and correct it by using smooth jumping method. The DPLL varies from minimum system clock frequency 60 to 1489 MHZ (Minimum) maximum of GHZ frequency of any range we can generate, since our design act as a general platform for any kind of application.
Key words: DCO, Delay Detector, Frequency Divider, Self Healing, Signal Shaping Circuit.
