the spread of cloud computing has increased the necessity of accumulating large amounts of data and performing high-speed data processing. Because strict consistency is not necessarily required for such large amount of data that cloud computing stores, a distributed Key Value Stores (KVS) is considered suitable for their data storage, based on an eventual consistency paradigm. In order to provide services such as SNS, mining and statistical processing of these data is indispensable. However because general distributed KVS systems are not designed for processing, these data must be transferred to distributed file systems such as HDFS, which enables data processing. the transfer cost issue has occurred in this case. To find a solution for this issue, we propose a method that performs high-speed data processing directly on a distributed KVS. In this paper, we extend the Apache Cassandra database, a distributed KVS that handles large amounts of data, to enable data affinity-based parallel processing. the parallel data processing mechanism runs the local processing on the stored values at each data node that stores the values, and it then returns only the results of the processing as an answer to a request. From the evaluation experiments, the proposed method is shown to be faster than the typically used Cassandra approach. In addition, even if the writing process is performed in the background while processing the data, the processing efficiency is appropriate for specific loads. the experimental results show that the data processing can be performed during the process of writing at approximately 10 Mbyte/sec if there are eight data nodes in the experiment environment.

Object detection is an important function for intelligent multimedia processing, but its computational complexity prevented its pervasive uses in consumer electronics. To process large-scale datasets in real-time, more resources and reliable infrastructures are required for spreading the data and running the applications across multiple machines in parallel. In order to detect a large number of objects in real-time, a task-parallel processing framework based on Storm is proposed.

this paper presents a combination of programming languages and web technologies used to deploy a modern remote controlled system. the hardware part of the system is a parallel port interface board that contains different types display devices, user-input components and some relays. the system functionality is based on some software applications developed using different techniques: the communication between the parallel interface, local computer and webserver PC is based on standard C, the user interface is developed using php, mysql, html and javascript technologies. Users can access full resources of the system if they are registered or only some demonstration and training sections as guest users.

this paper describes our ongoing effort to develop an efficient and scalable infrastructure to model and simulate near-field tsunamis in order to develop site-specific impact scenarios (e.g. the expected effects of the tsunami on land). Our goal is to be able to leverage this infrastructure in order to provide the necessary information to assist emergency planning, notification and response programs. Our primary focus is to produce the scenario information quickly by efficiently utilizing the available hardware, providing as much lead-time as possible for the response systems. We have been able to show that a distributedcomputing approach allows for parallel computation of simulations, resulting in shorter times between the occurrence of an event and the simulated output. Included in this paper is our proposed computational model, a summary of our infrastructure and an evaluation of our proposed distributed framework.
