Data transmitted from one location to the other has to be transferred reliably. Usually, error control coding algorithm provides the means to protect data from errors. Unfortunately, in many cases the physical link can not guarantee that all bits will be transferred without errors. It is then the responsibility of the error control algorithm to detect those errors and in some cases correct them so that upper layers will receive error free data. The polynomial code, also known as Cyclic Redundancy Code (CRC) is a very powerful and easily implemented technique to obtain data reliability. As data transfer rates and the amount of data stored increase, the need for simple and robust error detection codes should increase as well. Thus, it is important to be sure that the CRCs in use are as effective as possible. Unfortunately, standardized CRC polynomials such as the CRC-32 polynomial used in the Ethernet network standard are known to be grossly suboptimal for important applications, (Koopman, 2002). This research investigates the effectiveness of error detection methods in data transmission used several years ago when we had to do with small amount of data transfer and data storages compared with the huge amount of data we deal with nowadays.  A demonstration of erroneous bits in data frames that may not be detected by the CRC method will be shown. A corrective method to detect errors when dealing with humongous data transmission will also be given.

Scale Integration

With the large-scale integration of fracturing unit's on-site construction, traditional industrial buses are increasingly unable to meet the requirements for the quantity transmission between various equipment in large-scale fracturing units, and different models of different equipment manufacturers cannot cooperate with each other as there are "Islands of information" in the control system. This article uses industrial Ethernet as the physical medium for data transmission. In addition, different equipment manufacturers use OPC as the core technology of the fracturing unit control system network, and set up an intelligent fracturing unit control system, so that the control network can quickly, accurately, and safely control the fracturing truck control system. The sand truck control system monitors and analyzes, saves, and prints the construction data in the vehicle instrument. At the same time, the network control system uses the vehicle instrument as the core of the network. It can control fracturing vehicles from different manufacturers. The sand mixer truck performs network control, which effectively avoids incompatibilities between various equipment manufacturers at the construction site.

Voice Data

As an effectual simple wireless equivalent created in the telecommunications (telephone) industry, Wireless Asynchronous Transfer Mode (WATM) is utilized to stream unified traffics like video, data, and voice data. In the asynchronous data transfer mode, voice data transfer a packet with the same medium, and data share the networks and burst data. Effective WATM data transmission requires an extensive array of designs, techniques used for control, and simulation methodologies. The congestion of the network is among the key challenges that lower the entire WATM performance during this procedure, in addition to the delay in cell and the overload of traffic. The congestions cause cell loss, and it requires expensive switches compared to the LAN. Consequently, in this current study, the application of an effectual switching model together with a control mechanism that possesses multiple accesses is employed. The multiple access process and switching model are utilized to establish an effective data sharing process with minimum complexity. The switching model uses the synchronous inputs and output ports with buffering to ensure the data sharing process. The traffic in the network is decreased, and the loss of packets in the cells is efficiently kept to a minimum by the proposed technique. The system being discussed is employed through the utilization of software employed using OPNET 10.5 simulation, with the valuation of the WATM along with the investigational outcomes accordingly. The system's efficiency is assessed by throughput, latency, cell loss probability value (CLP), overhead network, and packet loss. Thus, the system ensures the minimum packet loss (0.1 %) and high data transmission rate (96.6 %)

The Ideal

In the Greek Classical period, the symposium—the social gathering at which male citizens gathered to drink wine and engage in conversation—was held in a room called the andron. From couches set up around the perimeter of the andron, symposiasts looked inward to the room’s center, which often was decorated with a pebble mosaic floor. These mosaics provided visual treats for the guests, presenting them with images of mythological scenes, exotic flora, dangerous beasts, hunting parties, or the specter of Dionysos, the god of wine, riding in his chariot or on the back of a panther. This book takes as its subject these mosaics and the context of their viewing. Relying on discourses in the sociology and anthropology of space, it argues that the andron’s mosaic imagery actively contributed to a complex, metaphorical experience of the symposium. In combination with the ritualized circling of the wine cup from couch to couch around the room and the physiological reaction to wine, the images of mosaic floors called to mind other images, spaces, or experiences, and, in doing so, prompted drinkers to reimagine the symposium as another kind of event—a nautical voyage, a journey to a foreign land, the circling heavens or a choral dance, or the luxury of an abundant past. Such spatial metaphors helped to forge the intimate bonds of friendship that are the ideal result of the symposium and that make up the political and social fabric of the Greek polis.

Abstract Background A “pill-in-the-pocket” anticoagulation strategy, guided by ECG data from an implantable loop recorder (ILR), has been advocated as a clinical strategy. However, a fundamental requirement is the ability to reliably obtain daily ECG data from patients. Objective To determine the reliability of daily ECG data transfer from ILRs. Methods We evaluated patients implanted with an ILR in whom we sought to withhold oral anticoagulation (OAC) unless atrial fibrillation (AF) was detected. The ILR transmits data nightly to a bedside monitor. Once received, the data are sent to a central server. Over the course of a month, we tracked for each patient whether ECG data were received by the server. Results The study included 170 AF patients with an ILR where we planned to withhold OAC unless AF was documented. Daily ECG data were automatically transmitted and retrievable in only 36 (21%) patients. Two (1%) pts had not a single day of connectivity, 6 (4%) pts were connected <7 days, and 16 (9%) pts were connected <14 days. Wireless connectivity was lost for >48 hours in 89 (52%) patients (Figure). Most patients experienced multiple reasons for data transmission failure within the month. Conclusions To determine whether an ILR guided OAC strategy is feasible, reliable daily transmission of ECG data is a fundamental prerequisite. Current technology facilitated daily ECG data transfer in only 1/5 of patients. In the remaining, there was either extended loss of connectivity or no connectivity at all. A “pill-in-the-pocket” anticoagulation approach is currently difficult given existing hardware limitations. Funding Acknowledgement Type of funding source: None

It discusses the reasons of the data transmission time delay and packets loss based on the theory of net data transmission. Aimed to the question of the time delay of data transmission and packets loss, the control system models are set up to analyze their influence to the performance of the control system. Based on the synchronous control model analysis with wireless data transmission, a method to control the system is reached with the state prediction when the communication error or data loss appears. It can control constantly when communication errors appear, and also it can get the most error period by numerical analysis.
