Abstract: All optical 3R regeneration is a key function of the future all optical network and ultra-long-haul transmission. In this paper, all-optical regenerator utilizes a Fabry-Perot (F-P) filter for clock recovery, four wavemixing based in a 500m-long highly nonlinear fiber and optical band pass filter for retiming and reshaping. A 10Gb/s RZ signal was transmitted through 1200 km with a power penalty of 1dB at a BER of 10-9 compared to the back-to-back case. All optical 3R is shown to improve the performance of input signals degraded by transmission impairments and timing jitter of 10ps is reduced.

Abstract: The main goal of this system is to design a locker security system using RFID and Fingerprint. In this system, only authenticated person can open the door. A security system is implemented containing door locking system using passive type of RFID which can activate, authenticate, and validate the user and unlock the door in real time for secure access. The advantage of using passive RFID is that it functions without a battery and passive tags are lighter and are less expensive than the active tags. This system consists of fingerprint reader, microcontroller, RFID reader, and PC. The RFID reader reads the id number from passive. The fingerprint sensor will check incoming image with enrolled data and it will send confirming signal for C# program. If both RFID check and fingerprint image confirmation are matched, the microcontroller will drive door motor according to sensors at door edges. This system is more secure than other systems because two codes protection method used.

Abstract: From decades, the work of symbolic computations cannot be ignored in real time calculations. During the discussion of various automated machines, for estimated calculations we came to know where there are inputs and the corresponding outputs the term error is obvious. But the error can be minimized by using different suitable algorithms. This study focusses on techniques used for error correction in numeric and symbolic computations. After reviewing on different techniques discussed before we generate analysis by taking some of the parameters. The Experimental results shows that these algorithm has better performance in terms of accuracy, performance, cost, validity, safety, security, reliability and power consumption.

ABSTRACT: It is shown the inexistence of neutrinos to define precisely the concept of relativistic’s mass; under this scheme, to elementary’s particles as electron and interaction’s particles like photons correspond an electromagnetic and virtual mass. Nucleons (protons and neutrons) have real or inertial mass for being composite particles, since inertia needs structure: it is provided by an interactive network originated by strong and weak forces. This mass is building up atoms and all the material world under Classical Physics and Chemistry’s laws.These actual masses may be considered as electromagnetic and virtual one (thanks to its charge), in order to establish the high energies level needed to obtain all particles physics (elementary or not), which are governed by the laws of Quantum Physics. With all this, one may set up amore reasonable and understandable new Standard Model, which being projected into Cosmological Model can get rid of some inconsistencies and concepts difficult to be admitted.

Abstract: This paper proposes and implements a low cost Vehicle Data Logging System using GPS and GSM. This system allows a user to trace the present and past positions recorded in SD card. This system also reads the current position of the vehicle using GPS, the data is sent via GSM service from the GSM network. The vehicle’s position including the driving speed, the UTC time and data are stored in the SD card for live and past tracking. All of that GPS data is sent to PIC 18F4520 by the Universal Asynchronous Receiver/Transmitter (UART) and also store in SD card. GSM also uses UART to transmit. To know the position of the vehicle, the owner sends a request through a SMS. The SMS sends to the authorized person through the GSM network. The travel history of the vehicle are stored in a file on an SD card in FAT format.This system is very useful for car tracking, for adolescent driver being checked by parent (speed limit exceeding, leaving a specific area). V The developed system is easy to use, requires no additional hardware, and permits the selection of the amount of data and the time intervals between the data recordings. In addition, the collected data can easily be transferred to a computer via a connected serial port.

Abstract: In liver scintigraphy, radioactive tracers, in addition to liver, are accumulated in other organs such as spleen. It leads to the presence of secondary source, which affects image quality. Therefore, knowing the influence of the noise arising from the secondary source and trying to reduce the additional data is necessary. In nuclear medicine imaging, using of energy window is a useful way to reduce the noise. In this paper, we try to find an optimum energy window to reduce the noise for two different low energy collimators. Liver scintigraphy images with and without activity in spleen were simulated by SIMIND software with different energy window percentages and with Low-Energy High-Resolution (LEHR) and Low-Energy General-Purpose (LEGP) collimators. We used with activity of 190 MBq. Spleen was outside of the camera field of view so that just its noise effects on the liver image is examined. Finally, the images of liver with activity in spleen were compared with that without activity in spleen by MATLAB code.

Abstract : Sediment transport has relationship with hydrologic input primarily river discharge and rainfall intensity. Fluctuation of river discharge and rainfall intensity have great effect on suspended sediment concentration. Bayesian Dynamic Linear Model (DLMs) is used to study relation of input hydrology and basin response variables. Response variables were taken from suspended sediment concentration and river discharge from a year July 2012 to June 2013 at two outlets at Padang sub-watershed (upstream) and Padang Hilir sub-watershed (downstream) of Padang watershed, North Sumatra. Datas were analyzed by regression analysis of Suspended Sediment Concentration (SSC) as a dependent variables, while river discharge and rainfall intensity as independent variables. The results showed that river discharge value are the highest on July 2012 and October 2012 at upstream and downstream of Padang watershed, respectively. The SSC value are the highest on July 2012 and April 2013 at upstream and downstream of Padang watershed, respectively. There is a weak correlation (r2= 0.002) between SSC and rainfall intensity at source points of outlet at upstream of Padang watershed. There is decreasing of forest, paddy and plantation areas but increasing of bush and farming areas from 2012 to 2015 at upstream of Padang watershed.

Abstract: Text to speech (TTS) synthesis is the automatic conversion of text into speech. Generally, TTS system consists of two phases. The first is text analysis, where the input text is transcribed into a phonetic or some other linguistic representation. The second one is the generation of speech waveforms. In this TTS system, text to phoneme conversion depends on dictionary based approach to get the exact phonetic transcription. Speech synthesis such as domain specific, phoneme based synthesis and unit selection synthesis are used for concatenating speech. For numerical text to speech system, domain specific synthesis is applied. In phoneme based synthesis, the input text is considered as word to produce sound. For input sentence , unit selection speech synthesis is applied. This TTS system is mainly used for visual impairments and handicapped people.

Abstract: This thesis describes the design and construction of digital multi-meter using PIC microcontroller. In this system, a typical multi-meter may include features such as the ability to measure AC/DC voltage, DC current, resistance, temperature, diodes, frequency and connectivity. This design uses of the PIC microcontroller, voltage rectifiers, voltage divide, potentiometer, LCD and other instruments to complete the measure. When we used what we have learned of microprocessors and adjust the program to calculate and show the measures in the LCD, keypad selected the modes. The software programming has been incorporated using MPLAB and PROTEUS. In this system, the analogue input is taken directly to the analogue input pin of the microcontroller without any other processing. So the input range is from 0V to 5V the maximum source impedance is 2k5 (for testing use a 1k pot). To improve the circuit adds an op-amp in front to present greater impedance to the circuit under test. The output impedance of the op-amp will be low which a requirement of the PIC analogue input is.

ABSTRACT: Mobile computing has become an invaluable and inevitable part of teaching and learning in educational institutions globally. Zimbabwean polytechnics are not spared and those institutions that have chosen to integrate mobile computing with existing teaching and learning applications stand to benefit more than their slow and stagnant counterparts. This paper is investigated whether mobile computing is being used in Zimbabwe Polytechnics. It is based mainly on primary research since no particular research has targeted Polytechnics in Zimbabwe and specifically the Polytechnic understudy in this area, thus a survey was conducted and the survey results were used as the main data source. However, secondary research was incorporated to see what other researchers have found in similar topics the world over. This paper identifies the mobile computing hardware technology, software and communication technologies used at the Polytechnic. It then outlines the achievements made in this area and the associated benefits of such achievements. Finally highlights the challenges currently being faced by the polytechnic in implementing mobile computing and the opportunities the institution can exploit by fully utilizing the technology. The main findings of this research were that Zimbabwe polytechnics in general and the polytechnic in particular have adopted usage of mobile computing to enhance their teaching and learning and administrative activities. There are visible and tangible achievements and benefits that have been realized. Opportunities have been identified which the polytechnic can exploit if it fully embraces mobile computing. However there are some challenges hindering the progress in this regard.

Abstarct: Tethering is a concept of sharing of internet of a device with other devices. It’s a low-cost, short-distance, wireless technology which employs the frequency hopping practice in the globally available ISM band to keep away from interference. In the tethering, to form a network, there is a concept of piconet containing master and slaves. These piconets are connected together to establish a big network called scatternet. There are several aspects on which scatternet working depends, like the piconets numbers and bridges, the bridge role, etc. Already established routes consume much more energy for the maintenance hence instead of this, routes can be created on-demand. Thus, consumption can be altered and routes flexibility will inclined. Failover is an another concept that I have included. It’s about transferring one’s control to the other device whenever first device is failed. In this thesis, I have proposed a QoS failover routing that will proficiently form the routes with the QoS desires and will prevent the stoppage of transmission if the transmitting node fails. It will pass its control to another node and allow it to transmit instead of it.

The focus of this study is to seek the relevance of investing in Information Technology (IT) by the students. The research takes into account 50 students studying at different disciplines at Dhaka University. The respondents were visited randomly to get the relevant data. The result of the study suggests that students’ academic quality and knowledge enhancement have a relationship with investment in IT though the relationship is not significant. The result of hypothesis testing shows that students those have invested in personal computer and internet secure comparatively higher cumulative grade point average (CGPA) rather than those who haven’t invested on these IT tools. But the likelihood of investing higher amount in IT will pay-off better CGPA is not found thus there is no association of good result and investing heavily on IT. However, the findings of this exploratory study offer insights that the money invested in IT for academic purpose is more advantageous than otherwise be invested especially for those students whose academic curriculum mainly decorated in accordance with the modern up-to-date era of Information Technology. Eventually, this study will help concerned students, guardians and academicians understanding how important IT is for student’s academic performance.

Abstract: Queues are common sight of many banks in Ghana. The obvious implication of customers waiting in long and winding queues could result to prolonged discomfort and economic cost to them; however increasing the service rate will require additional number of tellers which implies extra cost to management. This study therefore attempts to find the trade-off between minimizing the total economic cost (waiting cost and service cost) and the provision of a satisfactory and reasonably shortest possible time of service to customers, in order to assist management of the bank in deciding the optimal number of tellers needed. Data for this study was collected at the Ghana Commercial Bank Ltd, Kumasi Main Branch for one month through observations, interviews and by administering of questionnaire and was formulated as multi-server single line queuing model. The data was analyzed using TORA optimization Software as well as using descriptive method of analysis. The performance measures of different queuing systems were evaluated and analyzed. The results of the analysis showed using a five teller system was better than a four or a six-teller system in terms of average waiting time and thetotal economic cost, hence the study recommends that, the management should adopt a five teller model to reduce total economic costs and increase customer satisfaction.

Abstract: After the advent of the assessment reform in North America around the 1980’s, learning became considered as evidence for assessment. This latter came to support learning, adjust learning behavior and improve performance. Portfolio as a learner-centered assessment strategy is based on the philosophy which views assessment as an integral part of instruction. It is a purposeful, multidimensional process of collecting evidence that illustrates a student’s accomplishments, efforts and progress over time. This paper defines portfolio as a self-assessment and self-reflection tool with its various types. It explains its various uses and its main components, along with the main steps of its implementation. At the end, it gives a short description of portfolio’s main points of strength and weaknesses.

Abstract: Recent concerns over global warming as well as other well documented environmental impacts which arise from the utilisation of fossil fuels has led to intensified investigations to identify possible energy alternatives. These investigations sought to establish the feasibility of alternative energy sources to meet not only the increasing demand requirement but ultimately facilitate the realisation of the hypothetical ‘Zero net Carbon’ pollution target. However, while energy and environment enthusiasts consistently insist on the viability of Renewable Energy Technologies (RETs) as a conduit for meeting energy demand without compromising the need for sustainability, deciding which RET or indeed combination of RETs will be most appropriate based on the existing economic, legal as well as environmental framework remains a realistic challenge. This investigation therefore attempted to present a decision making process that will consider the four criteria inputs widely recognised as requirements for sustainable development. The RETs where subsequently evaluated via the consideration of these criteria as the only requirement for RET selection assuming the region under consideration was independent of the grid or a fossil fuel generator. The approach employed therefore presented a valid method for an initial and basic appraisal of RETs in the development of sustainable energy systems, with the defining assumption being that the technical indicator incorporated the ability of the RET to meet the primary load. A preferential ranking was finally achieved via the utilisation of simple matrix models thus facilitating the development of a theoretical basis for the practical implementation of the most appropriate RET.

Abstract: Vehicular Ad-Hoc Network (VANET) is a new communication paradigm creating a network on wheels. Communication between the vehicles provides for various safety and comfort applications. VANET is characterized by features like number of nodes, varying topology, constrained and high speed movement of nodes. All these features make routing in VANETs a crucial issue. This paper compares popular proactive, reactive and hybrid protocols in infrastructure less environments as availability of an infrastructure is not ubiquitous. Intensive simulations are carried out using IEEE 802.11p standard in the presence of realistic propagation model. Behaviour of protocols is studied in different situations by measuring performance in terms of QoS metrics like throughput , Packet delivery ratio (PDR), routing load and end to end delay.

Abstract: The meat of male P.pelagicus(n=3) was analyzed for protein, fat, moisture and ash contents by proximate analysis. The flesh of shark (Caracharhinus spp.)(n= 3),thalapath (Istiophorus spp.)(n= 3) were also analyzed for water-soluble protein content. Peptide-mapping was also carried out for the water-soluble protein fraction of all three types of samples. Moreover,the sub-samples (n=3) of the crab meat samples and commercial fish oil samples (n=3) were also analyzed for fatty acid profile and content, using gas chromatography. The results of proximate analysis revealed a composition of, 89.4±0.072 %( mean ±SE) moisture, 75.7±0.069% protein, 13.0±0.002% ash and 02.2±0.047% fat, in crab meat. The analysis water-soluble fraction revealed species-specific patterns on SDS-PAGE demonstrating greater amounts of myosin heavy chain and fimbrin compared to that of shark and thalapath flesh. As it was expected, a high content of polyunsaturated fatty acids were found in crab oil, representing 40.68 % of the total fatty acid content. The fatty acid profile exhibited greater percentages of oleic acid (28.03%) and eicosapentaenoic acid (EPA) (12.12%) when compared to existing data related to that of commercial fish oil. In conclusion, the study revealed high protein content and a low fat content in the meat of P. pelagicus. The water-soluble protein profile, meat of P. pelagicus could possibly be differentiated by peptide mapping which shows thick bands for the myosin heavy chain (MHC) and fimbrin. Oil of P. pelagicus carries relatively greater amounts of EPA and oleic acid. Thus, the consumption of crabs would help to prevent nutritional deficiencies in the future.

Abstract: Encryption is a tool for protecting and securing data. Security provides safety and reliability. As the need for communication is increasing day by day, there comes necessity of encrypting data in-order to ensure a secure communication. This paper presents application of genetic operators in the field of cryptography. As mostly tampering of data occurs in the network, the messages should be protected when it is transmitted through any network. This paper introduces a new encryption technique where the genetic operators ‘crossover’ and ‘mutation’ are used to encrypt messages, so as to protect the data during transmission. The goal is to provide a better encryption technique which is difficult for cryptanalysis.

Abstract: Clay mineralogy was studied in the soils of Arid Almanaqil Ridge. The soils are classified according to the American System (Keys to Soil Taxonomy, 2010) in the fallowing families: Fine loamy, mixed, isohyperthermic, TypicHaplustepts (unit1, sample A1 and A2), Fine, mont, superactive, Isohyperthermic, VerticHaplocambids (unit2, sample A3) and Fine, mont, superactive, isohyperthermic, TypicHaploustert (unit3, sample A4). Representative soil samples were collected from these units. These samples were samples A1 and A2 for unit1, sample A3 for unit 2 and sample A4 for uint3 respectively. Those samples were compared with samples from outside the study area from north of the study area (sample A5 and A6) and from the alluvium of the Blue Nile (sample A7), according to their lithology, topographic position, soil types and soil mapping units. Clay mineralogy of the samples was studied using X-ray diffractograms (XRD) techniques. The XRD diffractograms indicated the presence of smectite, chlorite, illite, and kaolinite as the major clay minerals in the soil of the study area and outside of the study area. The major clay minerals in these soils, Chlorite, illite and kaolinite could have originated from parent material. Smectite, showed an increasing trend in samples A7 (outside of study area) and sample A4 (unit 3). The CEC of clay minerals in unit 1 and 2 were less than 50 Cmol+/kg , which indicated that minerals with low CEC were dominant this result conformed with the XRD results that showed dominance of Chlorite, illite, and Kaolinite. Higher CEC values (more than 50 Cmol+/kg) of the clay were encountered in soils samples from unit3 (A4) and those from outside study area (Sample A7), XRD results showed that the samples were dominated by smectite. Moreover, the CEC values of clay minerals were consistent with results of XRD. The X-ray mineralogy indicated that the Vertisols and Aridisols of the study area had the same origin as that of the Gezira soils.

Abstract: this study aims to explain determinant factors of sectoral stock return in bullish and bearish condition at Indonesian capital market. This study used a multi-factor asset pricing model with sectoral stock return as the dependent variable and stock market return, interest rates, and exchange rate as independent variables. The Identification of stock market condition by using a Markov Switching Models, which are also used as the basis for segmenting the data into bullish and bearish conditions. Estimates of the model used the robust least square method. This study used data from Indonesian Stock Exchange to the observation period from January 1996 to December 2013. The results of this study were (1) simultaneously, stock market return, interest rates, and exchange rate affected the sectoral stock return in bullish and bearish condition. (2) Partially, the stock market return positively effect and is as a main factor in determining the sectoral stock return in all industries in either bullish condition or bearish condition, while the effect of the interest rates and exchange rate do not consistently affect the sectoral stock return in different industries and market conditions.
