Effective Technique for Optimizing Timestamp Ordering in Read Write/Write Write Operations

Effective Technique for Optimizing Timestamp Ordering in Read Write/Write Write Operations

trending technology, most enterprises tend to adopt large databases, but the inherent problem is how to ensure serializability in concurrent transactions that may want to access the data in the database so as to maintain its data integrity and not to compromise it. The aim of this research is to develop an efficient Timestamp Ordering algorithm and model in conflicting operations in read-write/write-write data synchronization. In read-write synchronization, one of the operations to perform is read while the other is write operation. While in the write-write synchronization, both operations are trying to access the same data item and both of them are write operations. If multiple transactions modify the same data item, the integrity of the database might be compromised if there is no proper control mechanism. Timestamp and C4.5 machine learning algorithm was used to develop an algorithm that ensures serialization and consistency of database. We adopted object Oriented Analysis and Design Methodology in the analysis of effective technique for optimization timestamp ordering scheduler in RW/WW synchronization. The proposed hybrid algorithm was able to carry out the RW and WW transactions in minimal time. It optimizes the cost of reading or writing in large datasets and enable speed access in the database system with huge volume of data; thus, eliminating the problem of coordinating concurrent access to a database system.

IMPLEMENTATION AND DESIGN OF 6T-SRAM WITH READ AND WRITE ASSIST CIRCUITS

IMPLEMENTATION AND DESIGN OF 6T-SRAM WITH READ AND WRITE ASSIST CIRCUITS

The 65nm technologies SRAM is implemented with read and write assist circuit technique. The project has been very challenging since it includes functional validation, transistor sizing, and layout of various circuits. Full functionalities of all the design features have been validated. Based on simulation results for the circuit it can be concluded that read and write assist circuitry is effective controlling power dissipation. Finally, the power dissipation of both the circuits incorporated is compared. The future scope of this project is density of the SRAM circuit can be increased by using less transistor SRAM cells. The performance of the module can be improved using low voltages. A 128 x 128 SRAM can be implemented using the basic module of this project. Speed of the SRAM can be improved by scaling down the technology.

Teaching bodies to read and write. A technosomatic perspective

Teaching bodies to read and write. A technosomatic perspective

I first look for an appropriate theoretical framework for thinking about how technologies of reading and writing constitute us as human subjects. I seek inspiration in a media-theoretical approach, and especially in the work of Harold Innis. However, I also point to a shortcoming to this approach and argue that we need to develop a technosomatic perspective, i.e. one which takes into account the bodily dimension of using technologies. Technologies are not merely objects and tools, but also – and even more importantly – the term refers to the repertoire of physical gestures and disciplines we need to acquire to operate these tools. With the help of the work of Bernard Stiegler and Giorgio Agamben, I argue that the sense of basic literacy training at school should be defined in terms of a strongly embodied sense of being able to produce letters and words. Throughout this article I will look at differences between traditional ways of learning to read and write, and digital ones. I finish this article by developing some ideas about what a transition towards a digital form of literacy might involve.

The Way I Learned to Read and Write

The Way I Learned to Read and Write

When I was a little girl, my mom asked my brother and I to write in our diaries everyday. People who have the same experience may get the same feeling as I do: it’s really boring. My brother and I didn’t always know what to write because we believed that everyday was no different for us. We ate, studied, played, and slept over and over again. So we usually wrote: “Today I ate… I had 7 classes and my teacher told us… What a wonderful day! ” Our mother was very angry when she read our diaries the first time. She told us that we had to recollect the details that occurred in our daily lives. She stressed that every day is different. Therefore, we had

Write read 3D patterning with a dual channel nanopipette

Write read 3D patterning with a dual channel nanopipette

Nanopipettes are becoming extremely versatile and powerful tools in nanoscience for a wide variety of applications from imaging to nanoscale sensing. Herein, the capabilities of nanopipettes to architect and build complex free-standing three-dimensional (3D) nanostructures are demonstrated using a simple double-barrel nanopipette device. Electrochemical control of ionic fluxes enables highly localized delivery of precursor species from one channel and simultaneous (dynamic and responsive) ion conductance probe-to-substrate distance feedback with the other for reliable high-quality patterning. Nanopipettes with 3050 nm tip opening dimensions of each channel allowed confinement of ionic fluxes for the fabrication of high aspect ratio copper pillars, zigzag and -like structures, as well as permitting the subsequent topographical mapping of the patterned features with the same nanopipette probe as used for nanostructure engineering. This approach offers versatility and robustness for high resolution 3D “printing” (writing) and read-out at the nanoscale.

Implementation Methodology of High Performance Multi Byte Data Access Control of AMBA Bus

Implementation Methodology of High Performance Multi Byte Data Access Control of AMBA Bus

If HWRITE signal is LOW it indication of write transfer operation i.e. the data is transferred from slave to the master. In the READ state the Master will give address (HAddr) and make HWrite signal to low. The data in the given address will be read and written into the FIFO. In this input data is giving from the MCLK and the output data is taking from the HCLK, here the read and write operations are the inputs to the READ FIFO. Here the stored data can be retrieved by the data out when the FIFO is EMPTY the EMPTY flag is activated.

client is required to hold a token that reflects the type of file access permitted to the client. To read a file a read token is required from the server. To write to a file the client must request a write token from the server. If a client requests a write token for a file that has several clients reading from it, the server will send a message to the reading clients to invalidate cached data from this file. This is to ensure that they see the most recent data in the file. In the DFS token-based scheme, close-to- open semantics need not be enforced because the outstanding data can be written to the server after the application closes the file. The server will notify the client to yield its token whenever another process wishes to access this file.

An automated wrapper based approach to the design of dependable software

An automated wrapper based approach to the design of dependable software

The main limitation of the proposed methodology, as it has been applied in this paper, is the need for source code access. Although no attempt has been made to constrain the means by which methodology steps can be met, it may be difficult to devise an appropriate combination of means when source code is not available. For example, the identifi- cation of read and write actions on important variables was performed using source code analysis. In situations where source code is not available this is not possible, meaning that an alternative approach must be employed. However, it should be remembered that the intention of the methodology is to aid in the design of dependable software during its development, when source code is normally available.

Concurrency Control in Distributed Caching.

Concurrency Control in Distributed Caching.

We borrow the following definitions from [23]. A synchronization variable S has only a single associated operation synchronize(S), which synchronizes all local copies of the data store. When the data store is synchronized, all local writes by process P are propagated to the other copies, whereas writes by other processes are brought in to P’s copy. Using synchronization variables to partially define consistency leads to the so- called weak consistency. Weak consistency models have three properties: 1) Accesses to synchronization variables associated with a data store are sequentially consistent. 2) No operation on a synchronization variable is allowed to be performed until all previous writes have been completed everywhere. 3) No read or write operation on data items are allowed to be performed until all previous operations to synchronization variables have been performed. Before a read operation, a request must own a read lock and before writing a value, it should own a write lock on the data item. All schemes used in the locking model use a thread pool at the origin server to handle requests [11]. In this model, a group of threads are pre-spawned during initialization to form the thread pool. This eliminates the overhead of creating a new thread for each incoming request. When a request arrives at the origin server, one thread from the pool is selected to handle the request. After the request has been handled, the thread is returned to the pool.

Title : Low Power Circuit Design for SRAM Using Hetro Junction Tunneling TransistorAuthor (s) :Suganya.S, A.Nandhini, Sindhumathi.K

V.Alternative Sram Design With Adiabatic Logic The elementary cell of proposed circuit consists of two high load resistors which is constructed of PMOS (MP1 and MP2), and a cross-coupled NMOS pair (MN1 and MN2). In order to reduce the energy dissipation in the elementary cell, the PMOS having off-leak current is used. Using the PMOS as a high resistor the cell area can be small compared with the conventional 4T-SRAM using poly resistor. NMOS switch (MN3) is necessary to restrict a short circuit current when the data is written in the elementary cell. In the proposed circuit, decreasing signal voltage on the write (or read) line is limited by transmission gate; however normal NMOS switch is better from the viewpoint of cell area if voltage drop is no problem.
