Data Acquisition and Control Using Microcontroller[ ]


This paper discusses the way to employ the microcontroller device for data acquisition and control operations in electricity transportation process. A Supervisory Control and Data Acquisition (SCADA) system is always used with Programmable Logic Control (PLC) to control electric power stations. In this paper, a microcontroller is used with SCADA system instead of PLC to control the whole electric network. Design of the implemented modules is introduced. It consists of three units: a collecting data/transmitter unit, a receiving unit and storage/dispatch unit. The reason for using wireless communication instead of Ethernet connection is increasing the data rate and making the cost of cables for network is lying down. The best wireless communication is Global System for Mobile (GSM)/General Packet Radio Switching Service (GPRS). The target for using microcontroller instead of PLC is proving that a microcontroller can do all what PLC could do; also it is much easier to implement a microcontroller network than it is to implement a series of PLCs. In addition the microcontroller is cheaper than PLC. It is very important to express a new type of Remote Transmission Unit (RTU) consists of a microcontroller integrated with GSM/GPRS module. MikroC compiler is the easiest program used in programming the microcontroller. Integration of microcontroller with Lab view program produces a new simulation for the fact event.

Design of High Performance EDAC Unit Using Decimal Matrix Code for 2-Way Set Associative Cache[ ]


Soft errors due to radiation are becoming the major concern sometimes leading to an irrepairable damage. Traditional methods to reduce these errors dealt with mitigation of SEU but as a consequence of decrease in node capacitance MBUs can occur. Some fault tolerant techniques based on matrix codes by combining various techniques together have been proposed which are complex involving much computational delay with effective correction of 2 to 3 faults. So when these types of codes are used for improving the reliability of memories such as cache memory, delay involved in accessing the data increases which is undesirable. This project is focused on implementation of decimal algorithm based EDAC unit involving lower computational delay overhead which can offer better fault tolerance and its application to an SRAM memory and 2-way Set Associative Cache memory of LEON-3FT processor prototype which used SEU protection based EDAC Unit to show that it can offer better fault tolerance. It is compared to other EDAC techniques to clearly show the improvement of its fault tolerance and reduced computational delay overhead. The analysis is done for 32 bit data and is observed that the proposed technique can detect 32 errors and can efficiently correct up to 8 adjacent errors and 5 random errors. Two dimensional error correcting code can detect up to 8 errors and can correct up to 4 adjacent errors and 3 random errors, SEC-DED code can detect up to 2 errors and Hamming can correct only 1 error code can detect and correct 1 error only involving 4 addition or subtraction operations and 32 EX-OR operations, 80 EX-OR operations, 257 EX-OR operations and 187 EX-OR operations with total delays 15.115ns, 16.116ns, 18.848ns and 19.289ns respectively.

Design of High Speed 32-bit Microarchitecture for Emulation of Quantum Computing Algorithms[ ]


Quantum computing has emerged as a revolutionary concept in the field of cryptography and data operations. Quantum algorithms have proved themselves to be much faster and efficient than their classical counterparts. Though we are still years away from solid state realization of quantum computers [1], currently software emulations [5] are used for implementing quantum algorithms. However, present day processors are incapable of dealing with the immense parallel architecture required by the quantum computation. This research paper focuses on the design of a 32 bit floating point processor incorporating the superscalar architecture which is capable of running quantum operations. The unique feature of the processor is that it supports an instruction set dedicated to basic quantum operations required for algorithms. The quantum states are stored in the register memory in 32 bit floating point format. The execution unit consists of multiple FPUs in order to support the parallel quantum operations. The superscalar design of Quantum Computing Unit (QCU) is the key component of the processor which makes it superior to the existing architectures.

Speech Recognition by Linear Prediction[ ]


Speech recognition is fundamentally pattern classification task. It is divided mainly into two components. The first component is speech signal processing and the second component is speech pattern recognition technique. The speech processing stage includes speech end point detection, pre-emphasis, frame blocking, windowing, calculating the Linear Predictive Coding (LPC) coefficients and finally generating the codebook by vector quantization. The second part includes pattern recognition system using Neural Network (NN). We use feed forward back propagation neural network for classification, both for speaker dependent and speaker independent system. Speech signals are recorded by an audio wave recorder in the normal room environment. The research work has been done using 50 different hybrid paired word (HPW) by 10 male and 10 female speakers. The performance of 95.7455% recognition rate for speaker dependent and 70.305% recognition rate for speaker independent was established.

An analytical model of the transient thermal behaviour of semiconductor device[ ]


In this paper, an analytical one dimensional mathematical model of the transient thermal behavior of semiconductor devices is pre-sented. The regions where the heat is dissipated are modeled as δ(x) source located at finite distance beneath the top surface. Three procedures including Fourier and Laplace transforms as well as Fourier series, for obtaining an explicit expression for the temperature space-time dependence are described in details. Simple analytical relations for the transient thermal impedance andthermal time constants are derived. It is shown that temperature time dependence can be described with only one parameter – rise time . Simple analytical expression of the thermal impedance has the same form as that obtained using the phenomenological model.

FINANCIAL SUPPLY CHAIN MANAGEMENT[ ]


Financial supply chain management consists of the holistic and comprehensive activities of planning and controlling all the financial processes both within a company and with the external parties. In contrast to physical supply chain, financial supply chain focuses on the flow of cash and other related financial transaction rather than the flow of physical goods. There are parallels in physical supply chain, information supply chain and financial supply chain. From the moment a purchase order is created, the information need to be transferred to the next parties. After the physical goods were received from suppliers, payment will be sent. The whole purchasing process consists of all three supply chains; effectively managing the supply chains can increase efficiency and accuracy. The traditional financial supply chain consists of many paper based document and paper forms, especially when international trade happens. Paper based purchase orders, invoices, checks and letter of credits are heavily involved; human mistakes and error inputs are common; as a result, there is decrease the efficiency of the company’s working capital management. The current financial supply chain management aims at eliminating the paper based documents, and improving the integrity of parties being involved, such as financial institutions, logistics, and suppliers. The two main cycles involve in the financial supply chain management are P2P (Purchase-to-pay) and O2C (order-to-cash). These two sets of processes and the relationship between them create the company’s working capital requirement. Treasurer should manage and integrate both cycles seamlessly in order to maximize the cash on hand during the operating cycle. Integrating ERP system with financial supply chain management helps the information flows to internal parties and external parties easily, and improves the integrity and quality of the financial information being transmitted. In this report, a case study using SAP ERP system in managing financial supply chain will be discussed in detail.

Biosynthesis of metallothioneins under cadmium stress, zinc and iron supplementation in liver and kidney of male albino rats[ ]


Cells react to stressful environments with a broad range of diverse homeostatic responses. Among an array of responses stress response proteins, including metallothionein (MT) play an important role against metal induced stress. The present study is carried out to know the role of MT in detoxification of cadmium (Cd) toxicity in rats before and supplementation with trace elements such as zinc (Zn) and iron (Fe). Male albino rats were treated orally with Cd at a dose of 1/10th of LD50 / 48h (i.e. 22.5 mg/kg) for 7, 15 and 30 days (d) long sojourn. 15d Cd treated rats were then subjected to trace element supplementations of Zn (12mg/kg) and Fe (40mg/kg) individually and in combination for another 7, 15 and 30d time intervals. After specific time intervals, rats were decapitated and tissues like liver and kidney were isolated and used for metallothionein studies. Purification and quantification of MT protein was carried out by the standard methods. Purified MT protein containing samples were subjected to SDS-PAGE. Clear visible bands were observed in the test tissues approximately at 6.5 KDa against standard low range molecular weight protein marker (Cat. No. M 3546). Further, MT protein levels were significantly elevated in the test tissues during Cd treatment and also after supplementation with Zn and / or Fe. Maximum MT protein synthesis was observed in 30d rat kidney under combined supplementation of both Zn and Fe. Thus, tissues that contain an excess amount of MT are resistant to Cd toxicity.

Agility Achievement and Load Handling System in Fat-Tree Data Center Network[ ]


A multi-rooted hierarchical tree topology is most widely used in many data center networks. It provides good utilization of resources as well as better performance, still fat tree Data Center Network has two limitations i.e traffic load balance and agility. This is because Data Center Networks (DCN) increasingly carries larger and longer traffic flows. As a result of this it is unable to support different traffic types efficiently and has no capacity to access all services by all servers. A work has done previously on load balancing, yet agility has not been solved. In this paper the Agility Handling Method (weighted least connection technique) has been implemented to achieve Agility in Data Center network. This technique improves load handling capacity and also increases the level of performance even in a more number of nodes in the network.

Modified Shifted Current Method for Extraction the Resistive Leakage Current of Metal Oxide Surge Arrester[ ]


Surge arresters are installed on transmission and distribution lines and in substations between phase and earth to reduce the failure rates of system. To monitor the degradation of surge arrester measurement of total leakage current is used. The gapless zinc oxide surge arresters enable the utility personnel to measure the leakage current due to its gapless physical configuration. The resistive leakage current is extracted from total leakage current to determine the health of surge arrester. As the resistive current increases the life of surge arrester gets decreases. In conventional method total leakage current is measured by using current shunts or current transformers with addition of applied voltage which is difficult to measure in online condition. Modified Shifted Current Method (MSCM) is used to extract the resistive current from the total leakage current without the need of the voltage signal. In this paper the extraction of resistive leakage component from the total leakage current of Metal-oxide Surge Arresters (MOSA) is done by using the technique Modified Shifted Current Method (MSCM) and simulated in MATLAB.

Electronic Skin - A Brief Overview[ ]


Human skin is an important organ. It consists of an integrated, stretchable network of sensors that relay information about tactile and thermal stimuli to the brain, allowing us to move the organs within our environment safely and effectively. inspired by human skin an ELECTRONIC SKIN is created by artificial means used for autonomous intelligent robots and biometric prosthetics, among other applications. The development of electronic networks comprised of flexible, stretchable, and robust devices that are compatible with large-area implementation and integrated with multiple functionalities is a testament to the progress in developing an electronic skin (e-skin) to human skin. E-skins are already capable of providing augmented performance over their organic counterpart, both in superior spatial resolution and thermal sensitivity. They could be further improved through the incorporation of additional functionalities (e.g., chemical and biological sensing) and desired properties (e.g., biodegradability and self-powering).Continued rapid progress in this area is promising for the development of a fully integrated e-skin in the near future.

Development And Management Of Virtual Teams[ ]


Globalization has enabled different businesses to conduct their business operations in the different areas of the world. Evidently, there are various benefits of the globalization such as the costs of everyday products are decreased. However, it is also difficult for the businesses to survive in this era of intense competition because of globalization. For that reason, businesses try to reduce their costs significantly in order to ensure their long-­‐‑term survival in their market. Resultantly, they opt for outsourcing because it enables the businesses to delegate everyday insignificant activities to the talented individuals in the different areas of the world at a lower cost. Moreover, it also enables the organization to focus on activities that are more important. However, it is difficult for businesses to develop and maintain virtual teams effectively as it is difficult to communicate effectively to everyone at the same time.

Environmental Effect of Parathion Methyl on Bio-chemical Changes and Detoxification Capacity[ ]


The aim of this study was to evaluate the environmental effects of the organophosphate pesticides, parathion methyl (PM) at sublethal dosage (1)-on antioxidant defense system such as reduced glutathione (GSH) and glutathione S-transferase (GST) in liver, (2)-on plasma lipid ans glucose constituents: total cholesterol (TC), triglycerides (TG) and plasma glucose (PG) in vertebrate, the Wistar rats and to investigate if taurin was able to modulates the PM-induced changes in plasma levels of TC, TG and PG. All these parameters were measured in rats, which were orally given a single dose of MP (2mg/kg body weight for 10 days) and supplemented or not with taurin (diluted in the drinking water at 2%, for 10 days). In these conditions and after a 24h post-treatment, GSH significantly increased and GST activity decreased in liver and both plasma levels of TC and TG significantly increased in rats treated with PM. These last results were not relieved in taurin treated rats administered PM's. We conclude that (1) the administration of subchronic PM causes changes in the antioxidative systems in liver and (2) the organophosphate, methyl parathion interferes with lipids and glucose metabolism in rat and suggests that taurin, in mammalian animals, could reverse PM-induced lipid and glucose metabolism alterations.
