The aim of the study is to develop tools of increasing a problem solving reliability in a heterogeneous distributed computing environment by applying a diagnostics of computing resources components and using an analysis of problem solving schemes. A scheme (a plan) is an abstract program for a problem solving. A special attention is paid to the calculation of a problem solving scheme reliability on...
This study utilizes a simple model for constructing sensor nodes — master controller combinations in the Internet of Things. The model combines hardware and software for embedded systems which measure a predefined set of parameters. The master controller manages several sensor nodes, collects data from them and provides data for clients. The paper introduces a proof-of-concept implementation based...
In this paper, the basic principle of synthetic test is introduced. The method that DSP (digital signal processing) make control and signal measurement for synthetic test in the synthetic laboratory is described in detail. The frame diagrams of hardware are given and the problems of withstanding interference in high voltage test are discussed. The test results show that the system measurement results...
In this paper, the oily sewage treatment using the technology of ceramic membrane filtration is described. The intelligent control system of distributed sewage treatment is designed. Using multiple ARM processor STM32F103VET6 for each module processing chip, point to point signal transmission through RS232, The operation parameters of each module and its operation status are set up by using several...
Independent validation of experimental results in the field of parallel and distributed systems research is a challenging task, mainly due to changes and differences in software and hardware in computational environments. In particular, when an experiment runs on different hardware than the one where it originally executed, predicting the differences in results is difficult. In this paper, we introduce...
The wide usage of hardware Intellectual Property (IP) cores and software programs from untrusted vendors have raised security concerns for system designers. Existing solutions for detecting and preventing software attacks do not usually consider the presence of malicious logic in hardware. Similarly, hardware solutions for detecting Trojans and/or design backdoors do not consider the software running...
Modern computer systems are exceedingly complex, and increasingly so. This makes it challenging for students with no background in computer systems to climb the mountain of 40 years of design, particularly within a constrained teaching timetable. Through the medium of FPGAs, we have designed an 8-week course to take students from basic digital electronics through to processor design, modern software...
Stochastic computing (SC) [1] has received attention recently as a paradigm to improve energy efficiency and fault tolerance. SC uses hardware-generated random bitstreams to represent numbers in the [0:1] range - the number represented is the probability of a bit in the stream being logic-1. The generation of random bitstreams is typically done using linear-feedback shift register (LFSR)-based random...
A large number of hardware faults are being caused by an increasing number of manufacturing defects and physical interactions during operation. This poses major challenges for the design and testing of modem Multiprocessor System-on-Chips (MPSoCs). Intermittent faults constitute a major part of hardware faults and their fault rates can be used as an indicator of the wear-out in a Processing Element...
Research funding bodies strongly encourage research projects to disseminate discovered knowledge and transfer developed technology to industry. Unfortunately, capturing, sharing, reproducing and building upon experimental results has become close to impossible in computer systems' R&D. The main challenges include the ever changing hardware and software technologies, lack of standard experimental...
As the city infrastructure becomes more intelligent, individuals will have access to many different flavors of transportation. As this growth continues, problems in the current structure are found. Particularly in the U.S., the first mile and the last mile of an individual's commute can be the weakest links due to the distance from their home to a public transportation acces point and from another...
Hardware management and resource tracking is an important activity in maintaining labs at institute and offices. The resources are spread across various labs; some of the systems are at different location of the office. The monitoring of these systems is itself a tedious task. In this paper a ‘Resource Tracker’ methodology is proposed that provides a method to track remote resources by identifying...
One of the most promising areas in Computer Engineering is certainly that of the Internet of Things (IoT) Systems. Moreover, such systems can be efficiently implemented in current Field Programmable Gate Arrays (FPGAs) comprising of either soft-core or hard-core CPUs. The design of an IoT system comprises of developments in both hardware and software whereas a productive IoT Systems Designer should...
This paper describes a series of short experiments collecting and analyzing ADS B data using IoT (Internet of Things) devices. The collection is performed using a Raspberry Pi single board computer, an RTL-SDR radio, custom software written for the project, and the open source dump1090 software program. This Raspberry Pi/RTL-SDR/dump1090 combination is used to collect ADS-B data. The data is captured...
We aim at developing software techniques which enables 32-bit transiently powered embedded systems to make progress across periods of energy unavailability without resorting to hardware modifications. Recently, we have seen a huge surge in wearable and smartbuilding centric sensing applications. However, these devices are integrated with batteries for charging which not only increases size and mass...
Computers are man-made machines which work according to the given set of inputs and perform some operation on the input to generate a new set of outputs. They can be programmed to perform huge and complex task yet they lack imagination and ability to understand things. On the hand human brain is a machine which can learn new tasks by process of acquiring knowledge and understanding through thought,...
File System is Data-Structure with Logic (method) to handle efficiently a group of information on disk. File systems come are classified according to their structure method of operation, speed of operation, scalability and flexibility size and security. A file system framework is an intends to sort out data anticipated that would be retained after a program terminates by giving methodology to store,...
Internet of things (IOT) can be considered as a combination of effective hardware and impressive software which results in smart objects which are able to communicate and interact among themselves. However, data flow accuracy between two movable devices is a growing problem. This paper proposes and implements two approaches: Discrete Cosine Transfer (DCT) and Inter-Process Communication (IPC) for...
