IEEE North Jersey Section

The North Jersey ComSoc Chapter, North Jersey Computer Chapter, and NY Section ComSoc Chapter present speaker Paul Nikolich on the topic of 802 LAN/MAN Standards.The IEEE Computer Society's 802 LAN/MAN Standards Committee has been developing LAN/MAN technical standards for Physical and Media Access Control interfaces since 1980 which have enabled ubiquitous data communications over wired (802.3 Ethernet) and wireless (802.11 Wireless LANs aka Wi-Fi) media that have changed the world. This talk will give a broad overview of the current technical standards development activities in IEEE 802 LMSC that will power the next generation of data communications infrastructure. Time will be reserved for Q&A after the talk. Additionally some information about how people can participate in standards committee, what skills are needed, and who can they contact in order to get involved or volunteer.Speaker Bio Below.Speaker(s): Paul Nikolich, Agenda: 7pm-8pm Seminar and Q&A.Virtual: https://events.vtools.ieee.org/m/308768

Microstrip antennas are in massive demand for several emerging applications such as biomedical devices, ultrawideband communication devices, radar applications, etc. Microstrip antennas are inherently narrowband and low gain antennas. Since their inception, various methods have been introduced to improve them. Most of the methods depend on the software that needs unlimited optimization runs, which increases the antenna design's computation cost. Theory of Characteristic Modes (TCM) is the powerful analysis technique that made antenna structure easy to understand and comprehend. As it gives physical insight into the antenna's structure, the analysis and design of the antenna may not need many optimization cycles. It was first introduced in the 1970s, but it was not till 2007 that this method hit the modern world again for planar antenna design. The reason behind the unmatched success of this method was the details it gives about the surface current behavior of the antenna in a user-friendly manner. Since then, CMA (Characteristic Mode Analysis) has been successfully applied to analyze planar structures and helps design and improve specific characteristics of antennas. Most of my research focused on designing and optimizing the UWB antennas using CMA. CMA can fully illustrate antenna structure with a finite number of resonant modes. Hence, it has the potential of simplifying complicated and tedious antenna design procedures.This talk will focus on the following: (a) Can characteristic modes analysis define the future of antenna design procedures by helping to reduce the complexity of antenna design procedure? (b) the possibilities of producing the compact and efficient antenna design using characteristic modes. (c) how surface currents can be controlled to produce optimized antenna designs.Speaker(s): Dr. Mahrukh Khan, Ph.D., Virtual: https://events.vtools.ieee.org/m/313636

IEEE North Jersey Section: RAS Chapter and SMC Chapter joint seminar onHuman-Robot Collaborative Learning of Human Welder Intelligence for Enhancing Human Welder Skills and Robotizing Complex Welding ProcessesYuMing ZhangJames R. Boyd Professor of Electrical Engineering, University of KentuckPlace: https://njit.webex.com/meet/zhouTime: 9:30am-10:30am, May 21, 2022For precision joining, skilled welders currently overperform welding robots due to their adaptation to the process. This is a kind of human intelligence that may be used to equip welding robots for them to become more intelligent and help welders to reduce the needed training time. A major challenge in learning such intelligence arises from the specular nature of pool surface that disqualifies diffuse reflection-based laser triangulation methods. To overcome this issue, the mirror surface is advantageously used to reflect a laser pattern away from the arc, simultaneously eliminating the arc illumination problem. To allow welders to freely demonstrate their skills, a human-robot collaborative system has been established where a welder carries a virtual torch, similarly as operating an actual one, without a sensor. The movement is measured at the virtual system and then followed by a robot which carries the sensor and performs the actual welding. The measured weld pool is displayed to the operator at the virtual site such that the welder can observe the change in the operation result to adjust his/her torch movement and other parameters. The true intelligence of the welder is thus contained in and can thus be extracted from the resultant data. For more complex welding processes that require operations of multiple welding torches/tools, their robotization are more challenging complex. A possible solution is also to learn from human welders as they are quicker learners who can adjust their operations to stabilize the complex welding process. This involves simultaneous operations from multiple welders and capture of the data needed to learn. Human-robot collaboration again provides an environment to enable the operation and capture the “true” data for learning of the intelligence needed despite the complexity of multiple operations.Bio: Dr. YuMing Zhang’s research focuses on intelligent robotic and human-robot collaborative welding systems.
