Abstract :

The main purpose of the paper is to present a CMOS current conveyor circuit which is best suited for the implementation of low- voltage, low-power and high bandwidth circuits. To achieve the bandwidth of current transfer function the circuit can be operated for a power supply of fraction of volt which is of MHz range and a power consumption of milli-watt range. Firstly, a class A current conveyor circuit operating from a single supply of fraction of volt having a high voltage swing capability is discussed and then the same circuit is modified to work as a class AB with a low voltage power supply in the fraction of volt range, while maintaining the same voltage swing capability. The body effect causes the threshold voltage variation and the current circuit realization is insensitive to it, which minimizes the layout area and makes both the circuits a valuable addition to the analog signal processing applications. The proposed structure has the required performance in terms of a bandwidth with level 3 CMOS technology and it operates as a linear circuit which is established with the help of 0.3 µm simulation using the PSpice software. In the field of analog signal processing this proposed current conveyor circuit has many applications. At 0.2µm the proposed circuit operates satisfactorily with high performance with the desired applications. The desired properties and the performance of the proposed circuit are confirmed by the PSpice simulation with the modeled parameters.

Abstract :

Congestion control in mobile ad-hoc networks (MANET) is an area of interest in networking which has got a noticeable attention by researchers during the recent years. There exist different mechanismsfor providing a solution to congestion problem in MANETs, each of which concentrates on one or more key parameters of MANET such as Load, Remaining Energy, Signal Strength, Priority Queueing etc. to achieve the goal.  Different proposals were made by various researchers with an intention of providing ananswer to the problem.  However, based on the design approach, each of those methods carry their own set of pros and cons.  In this paper, we propose a unique methodology to reduce congestion in MANET using a very intelligent queueing scheme that achieves an efficient usage of the limited network resources at the node.  This mechanism can be further combined with various existing routing protocols to achieve a significant performance in mobile ad-hoc networking while attaining the core objective.  As the proposed method operates at a very basic level of routing, it can be adopted easily byvarious existing congestion control protocols.

Abstract :

Today in the era of technology; security plays an important role especially when it comes to online transactions. There are various threats via which the victim is attacked and the data is lost or misused [8][5][[4][9]. Many counter measures have been taken like biometric, SSL, HTTPS, Intrusion detection system (IDS), Cryptography etc. According to [8] CIA Triad, Confidentiality, availability, and integrity are the three main objectives to provide security. Biometric ensures that only authentic user can access the data, by scanning the finger, iris, etc. Similarly, the idea behind the popular protocol SSL is to safeguard the path for traversing the data. Https ensures the safety of every transaction.  Whereas, cryptography ensures that the data should be secure even on the insecure path, hacked or accessed by an even unauthentic user. Cryptography deals with securing the data and fulfilling all the three above mentioned objectives. The paper is written with an objective to not only discuss cryptography but also discuss LIE- an encryption algorithm, how the encryption algorithm is tested, etc.  LIE is tested on various parameters like time, space, desirable properties etc.

Abstract :

Big Data is a new concept in the global arena. Data creates values in the economy and very parts of life. When we do some things, it creates some data. In the early history of computing data is a valuable thing to develop some new technique or new idea generation. In the beginning, there was data – first in file systems, and later in databases as the need for enterprise data management emerged. In 1970 with the rules of the relational model, began to gain commercial traction in the early 1980’s. As for “Big Data”, at least beyond the accumulation of scientific data, the need to manage “large” data volumes came later, first impacting the database world and then more recently impacting the systems community in a big way. Innovations in technology and greater affordability of digital devices have presided over today’s Age of Big Data, an umbrella term for the explosion in the quantity and diversity of high frequency digital data. Turning Big Data—call logs, mobile-banking transactions, online user-generated content such as blog posts and Tweets, online searches, satellite images, etc.—into actionable information requires using computational techniques to unveil trends and patterns within and between these extremely large socioeconomic datasets. New insights gleaned from such data mining should complement official statistics, survey data, and information generated by Early Warning Systems, adding depth and nuances on human behaviours and experiences—and doing so in real time, thereby narrowing both information and time gaps. Data have become a torrent flowing into every area of the global economy. Companies churn out a burgeoning volume of transactional data, capturing trillions of bytes of information about their customers, suppliers, and operations. millions of networked sensors are being embedded in the physical world in devices such as mobile phones, smart energy meters, automobiles, and industrial machines that sense, create, and communicate data in the age of the Internet of Things. Big Data has important, distinct qualities that differentiate it from conventional source data. The data from these innovative sources are highly distributed, loosely structured, large in volume, and often available in real-time. Big Data is also an important part of the data revolution as referenced in the recommendations made to the Secretary General by the High Level Panel of Eminent Persons on the post 2015 development agenda in their report "A New Global Partnership: Eradicate Poverty  and Transform Economies through Sustainable Development".  Better data and statistics will help governments track progress and make sure decisions are evidence based; they can also strengthen accountability. Mobile devices, sensors, tracking devices and other technologies have caused a fundamental change to the availability of source data. Digital data is now everywhere—in every sector, in every economy, in every organization and user of digital technology. While this topic might once have concerned only a few data geeks, big data is now relevant for leaders across every sector, and consumers of products and services stand to benefit from its application. The ability to store, aggregate, and combine data and then use the results to perform deep analyses has become ever more accessible as trends such as Moore’s Law in computing, its equivalent in digital storage, and cloud computing continue to lower costs and other technology barriers. A true data revolution would draw on existing and new sources of data to fully integrate statistics into decision making, promote open access to, and use of, data and ensure increased support for Analytic systems". “Big Data” being a hot topics in the field of data mining, varies seminars, symposiums and workshops are being arranged in Bangladesh, so that the section dealing with data analysis can have a better idea about the sources of data generation the huge volumes, the results that may be derived and the threats lying in Big Data analysis. Bangladesh Bureau of Statistics(BBS) being a sloe organization mandated for official Statistics, huge volume of data is generated every year, so a large section of officials is engaged in  data analysis, as a result a workshop on “Big Data” was held to give some idea of ‘what’, ‘how’, and ‘where’ about “ Big Data” . Likewise a workshop on Advance Data Management(ADM)  including ‘Big Data” was held in BUET on June 28 and 29’ 2013 in which several research papers from home and abroad were presented in this context. Our Thesis paper does not offer a grand theory of technology-driven social change in the Big Data era, rather it aims to highlight the main development and uses raised by “Big Data” management. This thesis paper covers three main issues: Big Data sources, Main challenges, and Areas of use.

Abstract :

Plate heat exchanger is one of the thermal energy transferring devices, which transfer the heat between different fluids. This is widely used in different applications because of its compact in size and higher efficiency compared to other types of heat exchangers. In this research work we are analyzing the performance of corrugated type plate heat exchanger using nano fluid in milk pasteurization process. In this work the Al2O3 nano particle is used to prepare nanofluid and the base fluid used as demineralized water. The main advantage of using PHE in this work is that it has high heat transfer area. The main focus of using nanofluid is that it has high thermal conductivity than base fluid like water, ethylene glycol, etc. The concentration of nanofluid is 0.3 % of its volume concentration. Here the milk is used as hot fluid and the nanofluid is used as cold fluid. The heat transfer rate is increased with increasing the concentration nanofluid, size of particle and type of materials used. From this work we expected that the enhancement high heat transfer rate.

Abstract :

Heat transfer is the predominant phenomenon in the engineering fields. It has created the huge challenge for dissipating the heat from one substance to another. Many researchers have found the different methodologies for increasing the heat transfer rate with the application of various research. In this paper we have proposed a new methodology for the heat exchanger in various aspects. We considered the two main aspects on the basis of design of the fluid flow and enhancement of thermal conductivity of coolant fluid by changing the chemical properties of the fluid. The properties are changed by the application of nano particles addition in the fluid. We have proposed the changes in the base fluids of nano fluids as the base fluids play an important role in the characteristics of nano fluid. The proposed design is that the tube inside the exchanger is helical coiled tube to increase the area which ensures the high compactness and mobility. The proposed design in our project leads to easier manufacturing of the parts thus making it cost effective. The preparation of the nano fluids is really a challenging one, as that purely based on the concentrations and mixing ratio of the nano powder with its base fluids. In our papper we have clearly explained about the mixing conditions of the nano particle. Our article compare the result of the overall heat transfer co-efficient between water and nano fluids.

Here we have considered the angle of the heat exchanger to know whether the heat transfer rate increases or decreases with increase in inclination angles of the exchanger. Here we have used the heat exchanger in various angles from 0` to 90` to find at which angle the heat transfer rate is maximum. The experimental analysis shows the heat transfer rate is maximum at 45` and it increases further with increase in the mass flow rate of both the fluids. In this proposal we used water as both hot and cold fluid with varying mass flow rates of the liquids.

Abstract :

Geometric distortion due to sensor and/or environmental error sources represent a big problem in the final reported accuracy of captured satellite images. Image to image registration is one of commonly used processes of geometric correction of captured images for updating digital maps and GIS databases. This research tested the effect of different raw image resolutions with respect to reference image resolution on accuracy of image registration process. The research algorithm is implemented using different resolution satellite images from two different sensors, IKONOS and LANDSAT8. The reference data is an image of 1.0meter resolution from IKONOS-2 satellite images. Spatial interpolation process is applied using first order polynomial technique with four ground control points from reference image, which are sharp defined and well distributed. Nearest neighbour technique is used for investigating intensity pixel values of resultant new corrected images. Geometric correction gave accurate results when using raw images with resolution same or higher than the reference image. The resolution of raw available images may be selected based on the required applications. Images with resolution lower than reference image can be used with applications that do not need high accuracy.

Abstract :

Early detection of infiltration is essential to minimize the injuries caused by infiltration. This is one of the most important tasks for nurses infusing intravenous (IV) solution or medications into the blood vessels. In this paper, infiltration phenomena were studied as a function of frequency and time using a bioelectrical impedance analyzer. When IV solution was properly infused into the vein on the back of rabbit, the impedance parameters (impedance, resistance, reactance, and capacitance) measured at five injection sites showed almost similar behavior with very slight standard deviations. On the other hand, the impedance parameters were significantly different before and after infiltration during infusing IV saline solution at the rate of 4 drops per minute into the small vein in the posterior ear of the rabbit. This is because the ears of the rabbit are thin and the vein is narrow so that IV solution temperately penetrates into the skin or subcutaneous tissue at infiltration and does not accumulate well thereafter. These studies may be applicable to infiltration studies in neonates with very small blood vessels.

Abstract :

This paper presents identification of a non-linear system for robot flexible arm as a black-box using Volterra series model. In most of the methods using Volterra series, too many number of parameters are estimated which is in contrast with the simplification principle in system identification. In this paper, for system identification of robot arm, kernels of Volterra series are developed using orthogonal functions that would reduce the number of parameters and consequently decreasing the identification time and increasing the accuracy and speed of convergence. At last, results of system identification of flexible robot arm based on expansion of Volterra series kernels through kautz orthogonal function are investigated with the results of the other method in literatures.
