logical effort based dual mode logic gates by mallikaMallika Naidu
Logic optimization and timing estimations are basic tasks for digital circuit designers. Dual Mode Logic (DML) allows operation in two modes such as static and dynamic modes. DML gates can be switched between these two modes on feature very low power dissipation in the static mode and high speed of operation in dynamic mode which is achieved at the expense of increased power dissipation. We introduce the logical effort (LE) methodology for the CMOS-based family. The proposed methodology allows path length, delay and power optimization for number of stages with load. Logical effort is the transistor sizing optimization methodology reduces the delay and power with number of stages with any static logic gate. The proposed optimization is shown for dual mode logic gates with logical effort using Digital Schematic Tool (DSCH).
HEVC 2D-DCT architectures comparison for FPGA and ASIC implementationsTELKOMNIKA JOURNAL
This paper compares ASIC and FPGA implementations of two commonly used architectures for
2-dimensional discrete cosine transform (DCT), the parallel and folded architectures. The DCT has been
designed for sizes 4x4, 8x8, and 16x16, and implemented on Silterra 180nm ASIC and Xilinx Kintex
Ultrascale FPGA. The objective is to determine suitable low energy architectures to be used as their
characteristics greatly differ in terms of cells usage, placement and routing methods on these platforms.
The parallel and folded DCT architectures for all three sizes have been designed using Verilog HDL,
including the basic serializer-deserializer input and output. Results show that for large size transform of
16x16, ASIC parallel architecture results in roughly 30% less energy compared to folded architecture. As
for FPGAs, folded architecture results in roughly 34% less energy compared to parallel architecture. In
terms of overall energy consumption between 180nm ASIC and Xilinx Ultrascale, ASIC implementation
results in about 58% less energy compared to the FPGA.

Welcome to International Journal of Engineering Research and Development (IJERD)IJERD Editor
The document summarizes a proposed design for a radix-8 Booth encoded modulo 2n-1 multiplier that can adapt its delay to match the critical path delay of a residue number system (RNS) multiplier. The design represents the hard multiple (3X) in a partially redundant form using a k-bit ripple carry adder to reduce carry propagation length. It also represents other partial products in a partially redundant, biased form. This allows the delay to be controlled by varying k. For a given n, valid values of k exist where the bias can be compensated by a single precomputed constant without affecting correctness.
Flexible dsp accelerator architecture exploiting carry save arithmeticIeee Xpert
This document proposes a novel flexible accelerator architecture comprising computational units (FCUs) that can efficiently perform DSP operations using carry-save arithmetic. Each FCU operates directly on carry-save operands and can be configured to perform templates of common DSP operations like multiplication and addition/subtraction.

The proposed architecture aims to achieve high computational density while reducing area and power compared to existing inflexible accelerator designs.
PERFORMANCE OF DIFFERENT CMOS LOGIC STYLES FOR LOW POWER AND HIGH SPEED VLSICS Design
Designing high-speed low-power circuits with CMOS technology has been a major research problem for many years. Several logic families have been proposed and used to improve circuit performance beyond that of conventional static CMOS family. Fast circuit families are becoming attractive in deep submicron technologies since the performance benefits obtained from process scaling are decreasing as feature size decreases. This paper presents CMOS differential circuit families such as Dual rail domino logic and pseudo Nmos logic their delay and power variations in terms of adder design and logical design. Domino CMOS has become the prevailing logic family for high performance CMOS applications and it is extensively used in most state-of-the-art processors due to its high speed capabilities. The drawback of domino CMOS is that it provides only non-inverting functions because of its monotonic nature. Dual-Rail Domino logic, (also known as clocked Cascade voltage switch logic where both polarities of the output are generated, provides a robust solution to this problem.

The design achieves a throughput of 1 billion pixels per second with a gate count of 22,200 gates.

A design and optimization of 3-5 GHz single ended Radio Frequency (RF) Low Noise Amplifier (LNA) for
ultra-wide-band (UWB) applications using standard UMC 0.18 μm CMOS technology is reported.
Designing of RF circuit components is a challenging job, since even after performing lengthy calculations

power out of 1.8 V supply.
This document presents a proposed aging-aware reliable multiplier design with an adaptive hold logic (AHL) circuit. The multiplier uses a variable-latency technique and can adjust the AHL circuit to achieve reliable operation under negative bias temperature instability and positive bias temperature instability effects, which degrade transistor speed over time. The AHL circuit can determine if an input pattern requires one or two clock cycles to complete, and can adjust its judging criteria to minimize performance degradation from aging. Experimental results on 16x16 and 32x32 column-bypassing and row-bypassing multipliers show the proposed design achieves significant performance improvements compared to fixed-latency designs.

This document presents a proposed aging-aware reliable multiplier design with an adaptive hold logic (AHL) circuit. The multiplier uses a variable-latency technique and can adjust the AHL circuit to achieve reliable operation under negative bias temperature instability and positive bias temperature instability effects, which degrade transistor speed over time. The AHL circuit can determine if an input pattern requires one or two clock cycles to complete, and can adjust its judging criteria to minimize performance degradation from aging. Experimental results on 16x16 and 32x32 column-bypassing and row-bypassing multipliers show the proposed design achieves significant performance improvements compared to fixed-latency designs.

The use of reversible logic gates in the design of residue number systems IJECEIAES
Reversible computing is an emerging technique to achieve ultra-low-power circuits. Reversible arithmetic circuits allow for achieving energy-efficient high-performance computational systems. Residue number systems (RNS) provide parallel and fault-tolerant additions and multiplications without carry propagation between residue digits. The parallelism and fault-tolerance features of RNS can be leveraged to achieve high-performance reversible computing. This paper proposed RNS full reversible circuits, including forward converters, modular adders and multipliers, and reverse converters used for a class of RNS moduli sets with the composite form {2 k p , 2 -1}. Modulo 2 n -1, 2 n , and 2 n +1 adders and multipliers were designed using reversible gates. Besides, reversible forward and reverse converters for the 3-moduli set {2 n -1, 2 n+k n , 2 +1} have been designed. The proposed RNS- based reversible computing approach has been applied for consecutive multiplications with an improvement of above 15% in quantum cost after the twelfth iteration, and above 27% in quantum depth after the ninth iteration. The findings show that the use of the proposed RNS-based reversible computing in convolution results in a significant improvement in quantum depth in comparison to conventional methods based on weighted binary adders and multipliers.
A new efficient fpga design of residue to-binary converterVLSICS Design
In this paper, we introduce a new 6n bit Dynamic Range Moduli set { 22n, 22n + 1, 22n – 1} and then present
its associated novel reverse converters. First, we simplify the Chinese Remainder Theorem in order to
obtain an efficient reverse converter which is completely memory less and adder based. Next, we present a
low complexity implementation that does not require the explicit use of modulo operation in the conversion
process and we demonstrate that theoretically speaking it outperforms state of the art equivalent reverse
converters. We also implemented the proposed converter and the best equivalent state of the art reverse
converters on Xilinx Spartan 6 FPGA. The experimental results confirmed the theoretical evaluation. The
FPGA synthesis results indicate that, on the average, our proposal is about 52.35% and 43.94% better in
terms of conversion time and hardware resources respectively.

Towards Efficient Modular Adders based on Reversible CircuitsIJSRED
This document discusses the design of efficient modular adders based on reversible circuits. It proposes combining residue number systems (RNS) with reversible computing to achieve an ultra-efficient computing paradigm for emerging applications. RNS allows for parallel and carry-free arithmetic, which is well-suited to take advantage of the properties of reversible circuits. However, existing RNS architectures were designed for ASIC implementation and need to be adapted for reversible circuits. Modular addition is a key operation in RNS since addition is used in forward and reverse conversion as well as other operations. The document presents implementations of modular adders using reversible gates like Feynman, Peres and HNG gates. Experimental results show modulo adders can be designed using reversible

The row/column approach provides a 24.4% power savings compared to the baseline. The fully pipelined architecture provides 16.4% power savings and higher throughput of 4.703 GHz by exploiting pipelining and parallelism.
A BINARY TO RESIDUE CONVERSION USING NEW PROPOSED NON-COPRIME MODULI SETcsandit
Residue Number System is generally supposed to use co-prime moduli set. Non-coprime moduli sets are a field in RNS which is little studied. That's why this work was devoted to them. The resources that discuss non-coprime in RNS are very limited. For the previous reasons, this paper analyses the RNS conversion using suggested non-coprime moduli set.
This document summarizes a research paper that proposes a novel modified distributed arithmetic scheme for implementing least mean square (LMS) adaptive filters with reduced area and power consumption. Some key points:

- The proposed scheme uses carry select adders for accumulation instead of previous carry save adders, reducing critical path length and improving efficiency.
- It allows concurrent lookup table updates and parallel filtering and weight updates to improve throughput.
- Implementations of adaptive filters with lengths of 16 and 32 using this scheme consumed 116mW and 158mW of power respectively, with area reductions compared to previous designs.

This document discusses the design and implementation of a universal set of integrated circuit gates for multiple valued logic (MVL) circuits using CMOS 180nm technology. MVL circuits can reduce the number of interconnections needed compared to binary circuits.

It describes implementing the gates in voltage mode by comparing input voltages to threshold voltages to discriminate the four logic levels, and using control switches to set the output levels. The goal is to prove the feasibility of these MVL gates for synthesizing combinational and sequential circuits using the proposed M
Non-binary codes approach on the performance of short-packet full-duplex tran...IJECEIAES
This paper illustrates the enhancement of the performance of short-packet full-duplex (FD) transmission by taking the approach of non-binary low density parity check (NB-LDPC) codes over higher Galois field. For the purpose of reducing the impacts of self-interference (SI), high order of modulation, complexity, and latency decoder, a blind feedback process composed of channels estimation and decoding algorithm is implemented. In particular, this method uses an iterative process to simultaneously suppress SI component of FD transmission, estimate intended channel, and decode messages. The results indicate that the proposed technique provides a better solution than both the NB-LDPC without feedback and the binary LDPC feedback algorithms. Indeed, it can significantly improve the performance of overall system in two important factors, which are bit-error-rate (BER) and mean square error (MSE), especially in high order of modulation. The suggested algorithm also shows a robustness in reliability and power consumption for both short-packet FD transmissions and high order modulation communications.
This document summarizes a research paper that implemented a pipelined CORDIC architecture in Simulink to generate sine and cosine values. The CORDIC algorithm uses only shift and add operations to perform trigonometric and other elementary functions. It was applied here in rotation mode to simultaneously compute sine and cosine of an input angle. A 12-stage pipelined CORDIC architecture was modeled in Simulink. The shifts and constants were hardwired to reduce resources and latency. Testing with an input of 0.6 radians showed accurate outputs for sine and cosine. The implementation demonstrated the utility of Simulink for modeling hardware systems and algorithms like CORDIC.

PARALLEL BIJECTIVE PROCESSING OF REGULAR NANO SYSTOLIC GRIDS VIA CARBON FIELD...ijcsit
New implementations for parallel processing applications using reversible systolic networks and the
corresponding nano and field-emission controlled-switching components is introduced. The extensions of
implementations to many-valued field-emission systolic networks using the introduced reversible systolic
architectures are also presented. The developed implementations are performed in the reversible domain to
perform the required parallel computing. The introduced systolic systems utilize recent findings in field
emission and nano applications to implement the function of the basic reversible systolic network using
nano controlled-switching. This includes many-valued systolic computing via carbon nanotubes and carbon
field-emission techniques. The presented realization of reversible circuits can be important for several
reasons including the reduction of power consumption, which is an important specification for the system
design in several future and emerging technologies, and also achieving high performance realizations. The
introduced implementations for non-classical systolic computation are new and interesting for the design
within modern technologies that require optimal design specifications of high speed, minimum power and
minimum size, which includes applications in adiabatic low-power signal processing.

Integration of the natural cross ventilation in the CFD software UrbaWindStephane Meteodyn
Nowadays, a lot of energy is spent for air-conditioning in the cities for offices and private-housing. A good knowledge of the urban micro climate around the buildings could allow using the wind for natural air ventilation. UrbaWind is an automatic computational fluid dynamics (CFD) code developed in 2008 by Meteodyn to model the wind in urban environment. A module was recently added to assess the buildings air ventilation. First UrbaWind integrates climatology according to the geographic location of the site. Giving the influence of the shape and urban planning on the wind behaviors, UrbaWind solves the equations of fluid mechanics with a specific model which allows taking into account the urban environment effects such as vortexes, venturi or wise effects. Finally, the software is able to compute the wind flow inside each internal volume according to the openings of the buildings.This paper presents this software that has been designed for energy engineers to optimize the energy consumption inside a building. This is also an important tool for architects and project managers to make a building. The shape of the building as well as the orientation and the location of the openings can be designed with the awareness of the wind-induced natural air ventilation.
UrbaWind, a Computational Fluid Dynamics tool to predict wind resource in urb...Stephane Meteodyn
Computational Fluid Dynamics (CFD) is already a necessary tool for modeling the wind over complex country side terrains. Indeed to maximize energetic yield and optimize the costs, before installing the wind systems, a good knowledge of wind characteristics at the site is required. Meteodyn has developed UrbaWind, which is an automatic CFD software for computing the wind between buildings for small wind turbines. Compared to rural open spaces, the geometry in urban areas is more complex and unforeseeable. The effects created by the buildings, such as vortexes at the feet of the towers, Venturi effect or Wise effect, make the modeling of urban flows more difficult. The model used in UrbaWind allows to take these effects into account by solving the equations of Fluid Mechanics with a specific model which can represent the turbulence and the wakes around buildings as well as the porosity of the trees. In order to validate UrbaWind’s results, different study cases proposed by the Architectural Institute of Japan have been set up. The three selected cases have an ascending complexity, from the simple block to the complete rebuilding of a quarter of the Japanese city of Niigata. The results validate UrbaWind as well for theoretical cases as for real cases by offering a minor error margin on the wind speed prediction.

ACTIVE SAFETY CONTROL TECHNIQUE TO PREVENT VEHICLE CRASHINGP singh
Alertness during driving is a key aspect. Even a small distraction for the driver may lead to genuine mishaps. The possible reasons can be obstacle, inadequate vehicle control system or human reflexes (e.g. shock) during sudden distraction. Therefore "Active" and "Passive" systems for vehicle control play a significant role in automotive safety. In this paper, we have discussed an active control technique to prevent the vehicle from crashing. Three different cases of vehicle speed are considered. The presented technique is designed to evaluate the possibility of collision for both front and rear side. The control action will be taken for safe and smooth driving under different situations like parking, urban driving and highway driving.
Numerical Analysis of Engineered Steel Fibers as Shear Reinforcement in RC BeamsP singh
Using suitable fibers and additives in concrete to enhance its performance is an important consideration in the concrete industry with regard to the structural aspects of concrete. The purpose of this project is to investigate numerically the effectiveness of the engineered steel fiber as shear reinforcement in RC beams. Here steel fibers completely replaces the shear reinforcement (stirrups & links). The dimension of beam taken was 1000*150*150 mm with aspect ratio 80. The beams were reinforced with 10 mm steel bars as secondary reinforcement and 12 mm bars as main reinforcement on the tension side. Numerical analysis using ANSYS R16.1 software package was carried out. The load-deflection curves for the beams with different dosage of fibers were drawn superimposing their numerical values. Initially, in all three cases the curve was linear elastic and about 80% of ultimate load they tend to be non-linear. It was observed that there was fair agreement between the results which indicates some favourable aspects concerning the use of steel fibres as shear reinforcement in concrete beams. It was investigated that the inclusion of steel fibres (Hook End Type) improves the shear strength of RC beams without stirrups by improving the matrix between concrete and steel fibers. Thus this project focuses in the design and analysis using the software ANSYS R16.1 for an alternative steel reinforcement with better or equivalent performance.
TRANSIENT ANALYSIS OF PIEZOLAMINATED COMPOSITE PLATES USING HSDTP singh
Piezoelectric materials have excellent sensing and actuating capabilities have made them the most practical smart materials to integrate with laminated structures. Integrated structure system can be called a smart structure because of its ability to perform self-diagnosis and quick adaption to environment changes. An analytical procedure has been developed in the work based on higher order shear deformation theory subjected to electromechanical loading for investigating transient characteristics of smart material plates. For analysis two displacement models are to be considered i.e., model-1 accounts for strain in thickness direction is zero whereas in model-2 in-plane displacements are expanded as cubic functions of the thickness coordinate. Navier’s technique has been adopted for obtaining solutions of anti-symmetric cross–ply and angle-ply laminates of both model-1 and model-2 with simply supported boundary conditions. For obtaining transient response of a laminated composite plate attached with piezoelectric layer Newmark’s method has been used. Effect of thickness coordinate of composite laminated plates attached with piezoelectric layer subjected to electromechanical loadings is studied.
ARTISANAL BOATBUILDING IN BRAZILIAN SHORES: CRAFTSMEN, BOATYARDS, AND MANUFAC...P singh
The majority of Brazilian small craft fishing fleet comes from artisanal boatyards which struggles with market pressure, professional social devaluation, and lack of raw materials. This work aims to provide a description about small craft artisanal boatbuilding in Brazilian shores to support initiatives to increase its social, economical, and environmental sustainability. On site visits and interviews about craftsmen social-economics; boatyards’ production organization; and manufacturing processes’ technological aspects were conducted. Results show that craftsmen are characterized by reasonable income and livelihood degree, compared with workers of similar educational level in their region. Relationships and work organization among them is traditionally structured and community based. Boatyards have sufficient structure, though access to new technologies and resources could be increased. Observed plank on frame building technique depends on workforce skills, commitment, and knowledge, as well as the resulting boats’ design and performance. Small craft artisanal boatbuilding is a living sector with its own dynamics, subjected to the creation and eventual adoption of new technologies. Instead of replacing the current manufacturing process by fibreglass reinforced polymer laminates, as suggested by some initiatives, it is believed that this sector’s sustainability can be increased by gradual introduction of tools, materials, and techniques while preserving its artisanal characteristics and qualities.
DESIGN AND FABRICATION OF THERMO ACOUSTIC REFRIGERATORP singh
In an age of impending energy and environmental crises, current cooling technologies continue to generate greenhouse gases with high energy costs. Thermo acoustic refrigeration is an innovative alternative for cooling that is both clean and inexpensive.
Thermo acoustic refrigerators are systems which use sound waves and a non-flammable mixture of inert gases to generate refrigeration effect. The main components are a closed cylinder, an acoustic driver, a porous component called a stack, and two heat-exchangers. Application of acoustic waves through the driver makes the gas resonant. As the gas oscillates back and forth, it creates a temperature difference along the length of the stack. This temperature change is due to compression and expansion of the gas by the sound pressure and the rest is a consequence of heat transfer between the gas and the stack. The temperature difference is used to remove heat from the cold side and reject it at the hot side of the system, producing cooling.

Mumbai is the region consisting of soft compressible marine clay deposits. There are several construction problems on such soils and thus ground improvement is need to be carried out. Vertical drains is generally preferred technique as accelerated settlement is achieved during the construction phase itself if planned accordingly. The concept of vertical drains is based on the theory of three dimensional consolidation as described by Terzaghi (1943). Based on this concept, a consolidation programme is developed and an attempt is made to determine the field to laboratory coefficient of vertical consolidation ratio by Taylor’s Square Root of Time Method and Casagrande’s Logarithm of Time Fitting Method for this region by considering the case study of Bhandup Lagoon Works Embankment. Based on this ratio, the rate of consolidation and time required for consolidation in the field can be determined knowing the consolidation parameters. Equations are developed by using output of the programme and it is explained.
ANALYSIS OF RING JET LASER GYRO RESONANT DITHERING MECHANISM P singh
This paper presents the design, manufacture, testing and improvement of newly developed piezoelectric torsion actuator which generates angular displacement using piezo ceramics and torsion bar. The proposed piezoelectric torsion actuator generates angular displacement during dithering, directly invoking the shear mode of the piezoelectric material and hence no complicated additional mechanism is needed. The piezo plates are formed from a rectangular PZT material duly poled along the axial direction. The dither mechanism is divided into four segments that are arranged in circular configuration. Each of the segments off our piezoplates is bonded in opposite poling directions with soldering adhesive. The key to design of such an actuator is to match the torsion resonant frequency of the actuator with the excitation frequency. FEA for the Torsion bar is carried out to find the different resonant mode sand mode shapes. Also, a set of torsion bars and resonator are analyzed to evaluate the maximum angular displacement and stresses on torsion bars. An experimental investigation in terms of electrical impedance and angular displacement measurement was conducted to verify the mode analysis. Based on the FEA analysis, a new material for the torsion actuator was selected having high Curie temperature and stable relative dielectric constant so that it has higher tentivity even after bonding the piezo plates on torsion bars and also wire soldering process. The design analysis was verified with the experimental results for incorporation of the selected mechanism for the production of dither in the system.
CLOUD COMPUTING: SECURITY ISSUES AND CHALLENGESP singh
Cloud storage is defined as "the storage of data online in the cloud," wherein a company's data is stored in and accessible from multiple distributed and connected resources that comprise a cloud. Although cloud service providers implement the best security standards and industry certifications, storing data and important files on external service providers always opens up risks. Using cloud-powered technologies means you need to provide your service provider with access to important business data. Meanwhile, being a public service opens up cloud service providers to security challenges on a routine basis. The ease in procuring and accessing cloud services can also give nefarious users the ability to scan, identify and exploit loopholes and vulnerabilities within a system. For instance, in a multi-tenant cloud architecture where multiple users are hosted on the same server, a hacker might try to break into the data of other users hosted and stored on the same server. The following paper deals with the service models of cloud computing along with types of cloud computing & characteristics of cloud. Further challenges and security issues in cloud computing is also discussed and at last conclusion and future demand for research in the field of cloud computing.

Among the operating temperatures selected for study 80℃, gives the best performance in heat transfer and the convection heat transfer coefficient. The results of the current work generally indicate that Nano fluids have the potential to enhance the heat transfer of a compact heat exchanger. Results indicate that, best overall heat transfer coefficient for the radiator is obtained at a hot fluid inlet temperature of 80℃, and at a flow rate of 0.075kg/sec.
DESIGN OF STACKED MICROCHANNEL HEAT SINKS USING COMPUTATIONAL FLUID DYNAMICP singh
The heat extraction problem is becoming an important factor in the development of micro-electronics. Over the last decade, micromachining technology has been increasingly used for the development of highly efficient cooling devices called heat sink because of its undeniable advantages such as less coolant demands and small dimensions. One of the most important micromachining technologies is micro channels. Hence, the study of fluid flow and heat transfer in micro channels which are two essential parts of such devices, have attracted more attentions with broad applications in both engineering and medical problems. Heat sinks are classified into single-phase or two-phase according to whether boiling of liquid occurs inside the micro channels
The microchannel heat sink is designed for electronic chips that could be effectively cooled by means of forced convection, by water flowing through the microchannels. This project presents a Computational Fluid Dynamics (CFD) flow simulation modeling, where water is made to flow across different cross-sectional microchannel heat sinks placed on heat source. The flow simulation of water and convective heat transfer are carried by using commercial software “Solid Works Flow Simulation”. In the CFD process stacked microchannels of various cross-sections viz., rectangular, triangular, pentagonal and circular are designed, then by defining the computational domain, boundary conditions as inlet mass flow (1e-5 kg/s),outlet pressure ( static pressure) and heat flux(750w/cm2) and by considering the parallel and counter flow direction of water in different cross-sectional microchannels the temperature drop in heat sink, pressure drop across the channels and amount of volumetric heat transfer coefficient are analyzed and compared.

STRUCTURAL RELIABILITY ASSESSMENT WITH STOCHASTIC PARAMETERSP singh
The performance of a structure [23] is assessed by its safety [1], serviceability [1] and economy [1]. Since we do not know the exact details of loads [4] acting on a structure at any time, there is always some uncertainty about the total loads on structure. Thus random variables (means stochastic variable) of loads and other parameters are the main criteria of design variables [18]. They vary with space and time. The input variables is never certain and complete. The safety factor provided in the existing codes and standers primarily based on practice, judgment and experience, may not be adequate and economical. Using the techniques presented earlier, we can design or analyze individual members in the contest of structural reliability [2][3][22][24]. However we are not examined how the system performs [23] or how to calculate the reliability of the structure as a whole.
EXPERIMENTAL STUDY ON THE ANALYSIS OF HEAT ENHANCEMENT IN CORRUGATED TWISTED ...P singh
In heat exchanger, the enthalpy is transferred between two or more fluids, at different temperatures. The major challenge in designing a heat exchanger is to make the equipment more compact and achieve a high heat transfer rate using minimum pumping power. In recent years, the high cost of energy and material has resulted in an increased effort aimed at producing more efficient heat exchange equipment. Furthermore, as a heat exchanger becomes older, the resistance to heat transfer increases owing to fouling or scaling. The heat transfer rate can be improved by introducing a disturbance in the fluid flow thereby breaking the viscous and thermal boundary layer. However, in the process pumping power may increase significantly and ultimately the pumping cost becomes high. Therefore, to achieve a desired heat transfer rate in an existing heat exchanger at an economic pumping power, several techniques have been proposed in recent years and are discussed under the classification section.
In this work, a study of transient heat transfer in double tube heat exchanger has enhanced. The inner tube of the setup was made with corrugation on both inner and outer walls by twisting the pipe from one end, which gives the more swirling motion to the fluid particles flowing over it. The flow inside the pipe was considered as turbulent, and the analysis was done experimentally and theoretically by using the ANSYS workbench. The experimental results were compared with the experimental values taken in the setup done by considering the inner tube as normal pipe. In both heat exchangers the values were taken and compared with the theoretical analysis. Temperature distribution and heat transfer rate were calculated and the details of the study have been discussed in this paper.
VLSI ARCHITECTURE OF AN 8-BIT MULTIPLIER USING VEDIC MATHEMATICS IN 180NM TEC...P singh
A Multiplier is one of the key hardware blocks in most fast processing system which requires less power dissipation. A conventional multiplier consumes more power. This paper presents a low power 8 bit Vedic Multiplier (VM) based on Vertically & Crosswise method of Vedic mathematics, a general multiplication formulae equally applicable to all cases of multiplication. It is based on generating all partial products and their sum in one step. The implementation is done using cadence Virtuoso tool. The power dissipation of 8x8 bit Vedic multiplier obtained after synthesis is compared with conventional multipliers such as Wallace tree and array multipliers and found that the proposed Vedic multiplier circuit seems to have better performance in terms of power dissipation.
VIBRATION BUCKLING AND FRACTURE ANALYSIS OF CYLINDRICAL SHELLP singh
Shell structures are widely used in civil, mechanical, aerospace and marine engineering applications (e.g. offshore oil tanks, automotive industry, aircraft and submarines). Like other types of structures, they are susceptible to various types of defect and damage such as cracking, corrosion, chemical attack and time-dependent material degradation, which may impair their structural integrity and affect their service life. The presence of cracks in a cylindrical structure can considerably affect its behavior. The effects of these imperfections on load carrying capacity and safety are thus important considerations in the design of cylindrical shell structures. This present work presents a finite element study on the vibration, buckling and fracture behavior of a cracked cylindrical shell with clamped type supports and subject to a time varying rotating speed. Vibration, linear elastic buckling and fracture parameters of a cracked cylindrical shell with time-varying rotating speed are analyzed. The effects of constant rotating speed, crack length and orientation of crack and length-diameter ratio of the cylindrical shell on the free-vibration and buckling behaviors are investigated.
HIGH SCHOOL TIMETABLING USING TABU SEARCH AND PARTIAL FEASIBILITY PRESERVING ...P singh
The high school timetabling is a combinatorial optimization problem. It is proved to be NP-hard and has several hard and soft constraints. A given set of events, class-teacher meetings and resources are assigned to the limited space and time under hard constraints which are strictly followed and soft constraints which are satisfied as far as possible. The feasibility of timetable is determined by hard constraints and the soft constraints determine its quality. Difficult combinatorial optimization problems are frequently solved using Genetic Algorithm (GA). We propose Partial Feasibility Preserving Genetic Algorithm (PFP-GA) combined with tabu search to solve hdtt4, “hard timetabling” problem a test data set in OR-Library. The solution to this problem is zero clashes and maintaining teacher’s workload on each class in given venue. The modified GA procedures are written for intelligent operators and repair. The PFP-GA in association with Tabu Search (TS) converges faster and gives solution within a few seconds. The results are compared to that of using different methodologies on same data set.
Due to its impact on human health and the nature surrounding us, diesel engine emissions have been significantly reduced over the last two decades. This reduction has been enforced by the legislating organs around the world that gradually have made the manufacturers transform their engines to today’s complex high‐tech products. One of the most challenging area to meet the legislations is the emissions of the diesel engine which are the products of the combustion of diesel fuel. More restrictions have been imposed by the some governments to reduce these emissions to a level such that will not cause any harmful impacts for the environment after releasing them to the atmosphere. This paper examines the effects of combusting a mixture of diesel fuel, water, and surfactant which forms emulsion on the nitrogen oxides, or NOx, carbon monoxide CO, carbon dioxide CO2, sulfur oxides SOx emissions and particulate matter (PM) from a compression ignition diesel engine. Previous research has attributed the observed reduction of these emissions to a suppression of flame temperature due to quenching effects from the water, thereby reducing thermal NOx formation and other pollutants. The focus of this review paper will be on experiments were conducted a using diesel engine with pure diesel fuel and emulsion of water-diesel. Furthermore, results from the testing diesel fuel that mixed with varied ratios of water balanced with a surfactant to stabilize the emulsion will be presented and discussed. Three different samples of water- diesel emulsion were used with 10 % water and 90 % diesel, 20 % water and 80% diesel, and 30 % water and 70 % diesel (by volume) respectively to conduct the experiments in the lab . The purpose was to see the impact of adding the water from 10 % up to 30 % (by volume) to the diesel fuel making the emulsion fuel to explain what will occur to the emissions and the performance of the engine. The data shows significant NOx emission reduction when using the emulsion water diesel fuel of 30 % water (by volume) in diesel. These results are correlated with a thermodynamic first law analysis to estimate the adiabatic flame temperature of the standard fuel and fuel-water emulsion cases. Results indicate that thermal NOx is indeed reduced by quenching and flame temperature suppression confirming reports in the literature. Recommendations are given for further studies, including improving the fuel—water emulsion and considerations for long-term testing.
USAGE OF ETHANOL BLENDED PETROL: EXPERIMENTAL INVESTIGATIONS OF REDUCTION IN ...P singh
An experimental study was conducted to evaluate what extent ethanol blends in Petrol helps in reduction of pollution levels of SI engines exhaust emissions. Ethanol blends E5, E10, E15, E20, E22 were tested and found considerable reductions in the pollutant levels of CO, CO2, HC. The results indicate better combustions in petrol engine with ethanol blends. The reductions in HC and CO were to the extent of 80% to 90% compared to pure petrol fuelled IC engine.
DESIGN CALCULATION FOR EQUIPMENT AND COMPONENTS SPECIFICATION OF LUBRICATING ...P singh
The lubricating oil system is primarily used to lubricate wear surfaces to minimize friction losses, it cools internal engine parts which cannot be directly cooled by the engines’ water cooling system and it cleans the engine by flushing away wear particles amongst others. Adequate lubrications require lubricant (oil) with sufficient film strength to withstand bearing pressure and viscosity index low enough to allow adequate flow when subjected to heat. The system consist of the tanks (storage, settling, sump and head), lube-oil pumps, strainers, oil coolers, piping, valves, and fittings, lubricating oil purifier, sub system and condition monitoring devices amongst others. The lubricating oil system for a tug boat whose transmitting power is about 955KW was calculated mathematically to obtain the flow rate of the shaft line bearing cooling oil, stern tube bearing cooling oil, main engine camshaft bearing cooling oil and main engine camshaft bearing cooling oil. Modelled equations were employed to obtain the camshaft lube-oil pump capacity, surface area and storage tank. The cylinder lube-oil storage and density tanks were estimated to be 1m3 while the transfer pump is calculated to be approximately 0.4m3/hr. The various suction and discharge diameters and velocities of pumps in the lubricating oil system were determined; it was observed the suction pipe diameter is always bigger than the discharge pipe diameter while the discharge velocity is higher than the suction velocity for all the pumps including the camshaft lube-oil pump, cylinder oil transfer pump and main lube-oil transfer pump. This is a clear indication that the said design process met the international standard for the design of such a tug boat. Similarly the shaft line bearing cooling oil pipe, piston bearing cooling oil pipe and main engine lube-oil pipe discharge velocities were seen to be at the acceptable limits obeying the classification rules. All designs were done in accordance to the Lloyd’s specification rules and regulations for a sea going tug boat.

Webinar: Designing a schema for a Data WarehouseFederico Razzoli
Are you new to data warehouses (DWH)? Do you need to check whether your data warehouse follows the best practices for a good design? In both cases, this webinar is for you.
A data warehouse is a central relational database that contains all measurements about a business or an organisation. This data comes from a variety of heterogeneous data sources, which includes databases of any type that back the applications used by the company, data files exported by some applications, or APIs provided by internal or external services.
But designing a data warehouse correctly is a hard task, which requires gathering information about the business processes that need to be analysed in the first place. These processes must be translated into so-called star schemas, which means, denormalised databases where each table represents a dimension or facts.
We will discuss these topics:
- How to gather information about a business;
- Understanding dictionaries and how to identify business entities;
- Dimensions and facts;
- Setting a table granularity;
- Types of facts;
- Types of dimensions;
- Snowflakes and how to avoid them;
- Expanding existing dimensions and facts.
