This paper presents a feature comparison between the 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) Release 8 and Institute of Electrical and Electronics Engineers (IEEE) 802.16m and preliminary system performance comparison. As Orthogonal Frequency Division Multiple Access (OFDMA) mobile broadband air interfaces, LTE and IEEE 802.16m are both International Mobile Telecommunications-Advanced (IMT-Advanced) technologies. LTE and IEEE 802.16m, which both make use of Multiple-Input Multiple-Output (MIMO) channels, have their own features and advantages. This paper compares some features between LTE and IEEE 802.16m in terms of frame structure, effective bandwidth, Hybrid Automatic Retransmission Request (HARQ) and Modulation and Coding Scheme (MCS), which is a valuable replenishment to the former work. The system simulation results show that LTE and IEEE 802.16m achieve similar performance although they are different communication evolution systems from different specification work groups.

As part of the Very High Speed Optical Networks (VHSON) Demonstration Program, a simulator has been developed. The Scalable Coherent Interface Network Interface Functional Simulator (SCINIFS) addresses the Institute of Electrical and Electronic Engineers (IEEE) standard 1596-1992 for the Scalable Coherent Interface (SCI). In addition, SCINIFS addresses the evolving work of IEEE project P1596.6, entitled SCI Real-Time (SCI/RT). The SCI/RT project addresses extensions to IEEE Standard 1596 that seek to enhance SCI's utility for real-time fault-tolerant computing applications. SCINIFS addresses the functional behavior and performance of SCI/RT nodes when connected in a ring. The development of the simulator, early results and future work to model SCI switches are described.

This Innovative Practice full paper presents a software system which purpose is to be used to compose online laboratory experiences.Online Laboratories have improved their reliability and interoperability thanks to innovative developments proposed in recent years. New companies in this area have proposed novel interaction mechanisms such as the inclusion of immersive graphic user interfaces as well as the possibilities for access laboratory experiments as a service, having the alternative of just paying for the laboratory services demanded, for an specific class or for individual users. In terms of technology it is now possible to have multiple laboratory instances running from a single laboratory infrastructure or laboratory station. In terms of standardization, big efforts have been made by the Institute of Electrical and Electronics Engineers (IEEE) and the community of Online Laboratories to release in 2019 the first standard 18762019 - IEEE Standard for Networked Smart Learning Objects for Online Laboratories.The software system presented in this work uses a set of available resources including virtual laboratories (simulation based), local laboratory equipment, remote laboratories, laboratory activities, assessment definition and learning content (text, audio, video, etc). The system provides to the users a friendly set of tools to compose their laboratory experiences, following the IEEE 1876-2019 standard definition. The output composed laboratory experiment is saved as a Smart Laboratory Learning Object (SLLO) including mechanisms to be self-adaptable according to variables such as laboratory activities difficulty level, user previous results on the same or similar laboratory activities, and user expertise in the topic (determined based on information retrieved from the Learning Management System LMS).

Now that the market for electrical apparatus has become global, there are efforts underway to compare standards with an intent to harmonize these standards. The Institute of Electrical and Electronics Engineers (IEEE) has made strides in this area. Specifically, the Electric Machinery Committee (EMC) of the IEEE Power Engineering Society is at the forefront of the IEEE harmonization effort. This paper gives some historical background and summarizes the details of this effort.

Over the past several years a growing focus on improved electrical safety has arisen. A better understanding of both electrical shock and arc flash hazards faced by personnel working on or near energized equipment has led to consensus standards such as the NFPA-70E. These standards deal primarily with safe work practices - designed to identify and quantify the hazard, then assure that personnel are clothed with appropriate personal protective equipment (PPE) to reduce the risk. Consensus opinion among safety experts is that the best method to reduce the risk of injury is by designing the hazards out. The next frontier in reducing electrical injuries will arise from improved designs of electrical products which mitigate hazards by design. One primary product area of interest is the low-voltage motor control center used for control of motors rated 1000 volts and below. In process applications such as cement, pulp and paper and petroleum and chemical plants, maintenance personnel often find it necessary to work on, or near, energized motor control centers while performing maintenance and operational activities. This paper will review work in progress by the Institute of Electrical and Electronics Engineers (IEEE) Working Group 1683 ldquoStandard for Motor Control Centers Rated up to 1000 volts with Requirements Intended to Reduce Injuriesrdquo Working Group. This group was initially formed by the IEEE Industry Applications Society Petroleum and Chemical Industry Committee and is working on ideas to improve the functional design and test requirements for motor control centers rated up to 1000 volts ac 50/60 Hz with specified safety and reliability features. The paper will briefly review the emerging standard and advise engineers that are interested in how to get involved to offer inputs for improving the standard. Information on new safety based low-voltage motor control center designs that have been recently introduced by several manufacturers will be reviewed. The review will show how the industry is responding to the product need articulated by the user community and the IEEE 1683 Working Group for product safety by design.

Numerical calculations of exposure to magnetic field of operators of suspended hand-operated resistance welding guns were performed using the own homogeneous, flexible human body models CIOP-MAN of the 95th and 5th percentile of adult men dimensions (185 and 164 cm in height), in 16 exposure situations with various postures of operator - typical for automotive factory. An assessment concerned calculated values of an induced electric field (E in ) in the brain and the heart - according to the ICNIRP (International Commission on Non-Ionizing Radiation Protection, 2010) and the IEEE (Institute of Electrical and Electronics Engineers, 2002). The results show applicability of flexible human body models in exposure evaluation based on E in values, even homogeneous. The values of E in in the brain and the heart are up to 34% higher when calculated following ICNIRP requirements than the values calculated following the IEEE method. The values of a welding current producing a B-field in the heart area of 100 µT/50Hz (i.e. the exposure limit for cardiac pacemakers users provided by ACGIH (American Conference of Governmental Industrial Hygienists, 2016) and CENELEC standard (European Committee for Electrotechnical Standardization)) are in the range of 0.43–1.6 kA, which is significantly lower than the typical current used in the industry (5–15 kA). Cardiac pacemaker users should not operate welding guns, as a result of the individual risk assessment required by the European directive on workers' protection (Directive 2013/35/EU).

Fraud detection in healthcare claims using machine learning: A systematic review.

Concurrency control and recovery mechanisms are essential for ensuring reliability and consistency in distributed database systems (DDBS). This systematic review examines recent advances between 2020 and 2025, focusing on trends, techniques, and performance models. Following the PRISMA protocol, studies were sourced from the Association for Computing Machinery (ACM) Digital Library, the Institute of Electrical and Electronics Engineers (IEEE) Xplore, SpringerLink, and ScienceDirect using targeted keywords and strict inclusion criteria. Concurrency control approaches are grouped into pessimistic methods, such as Two-Phase Locking (2PL) with high latency under contention, optimistic methods offering higher throughput but increased abort rates, multiversion systems providing read scalability, and adaptive machine learning hybrids that reduce latency in conflict conditions. Recovery mechanisms include Write Ahead Logging (WAL) with minimal performance loss, checkpointing and shadow paging with moderate degradation, and distributed commit protocols like the Paxos consensus protocol that maintain high availability. Performance modelling through queuing theory and Markov chains shows that Optimistic Concurrency Control (OCC) has higher rollback probabilities under heavy load, while Two Phase Locking (2PL) reaches throughput limits at high transaction rates. The review offers a decision framework linking workload characteristics to suitable mechanisms and highlights gaps such as inconsistent benchmarking and limited industrial validation. Future research should focus on unified benchmarking, intelligent adaptive models, and resilient recovery methods for distributed environments.

After that, the focus will be on the 46 year-long history of the presence of IEEE in the former Yugoslavia region and especially on the development and current state of the IEEE Serbia and Montenegro Section.

Providing quality of service (QoS) for real time applications over wireless local area networks is becoming a very challenging task due to the diversity of multimedia applications. Concurrently, there are numerous wireless local area networks WLAN(s) devices that are rising today. In the current paper, we focus on Institute of Electrical and Electronics Engineers (IEEE) 802.11n because it was designed to support a high data transmission rate (towards 600 Mbps). It is based on frame aggregation schemes that accumulate many subframes to be transmitted into a single larger frame. Thus overheads are reduced, efficiency and throughput are improved. However, it increases delay particularly for low rate applications. In fact, when the queue is empty, the medium access control layer (MAC) has to wait other packets to arrive in the queue to construct the whole aggregated frame. Moreover, if flows are not served, they will be accumulated in the queue causing an increased delay. To overcome these limitations, we propose a new dynamic frame aggregation (DFA) scheduler to provide QoS satisfaction to real time services. DFA schedules flows based on urgency delay and waiting delay, then it dynamically adjusts the payload size of aggregated frame. Conducted simulations prove that the proposed DFA scheduler provides QoS delay and throughput guarantee, and it reduces the number of dropped packets. Copyright © 2015 John Wiley & Sons, Ltd.

The Institute of Electrical and Electronics Engineers (IEEE) is the largest professional engineering society in the world. With over 250,000 members, the IEEE represents the fields of electronics, computers, and electrical power engineering. Given its size and prominence, it is not surprising that the IEEE chose to celebrate its 100th anniversary in 1984 in a big way. To record its accomplishments for posterity, the institute sponsored two book-length histories-The Making of a Profession by A. Michal McMahon and Engineers & Electrons by John D. Ryder and Donald G. Fink. In addition, to make the history of electrical engineering better known to its members and to the general public, the institute had its Center for the History of Electrical Engineering prepare a poster exhibit. Titled A Century of Electricals, this exhibit is a mix of rich images, of lively text, and of provocative topics and thus is a fitting way for this major society to celebrate its centennial.
