This document discusses using TutorTIMS software to implement and generate Orthogonal Frequency Division Multiplexing (OFDM) signals. The objectives are to introduce OFDM, learn how to use TIMS modules to create an OFDM generator, and generate and analyze OFDM waveforms. Key TIMS modules used include the sequence generator, multiplier, encoder, phase shifter, adder, and tunable low-pass filter. OFDM works by splitting a data stream into multiple lower rate streams, modulating each onto a subcarrier, and recombining the signals.

Practical Troubleshooting and Problem Solving of Ethernet NetworksLiving Online
While the basic structure of Ethernet has not changed much, the faster technologies such as Fast Ethernet and Gigabit Ethernet have increased the complexity and choices you have available in planning and designing these systems. As Ethernet has become more complex, a number of misconceptions have arisen as to how Ethernet functions and how the system should be optimally configured. This manual addresses these issues in a clear and practical manner, thus enabling you to apply the technology quickly and effectively in your next project. This manual commences with a brief outline of the Fundamentals of Ethernet and its operation.
The method of access is discussed in depth, and topics such as full duplex and auto negotiation are explained. The best methods of designing and installing the cabling systems are then explored with the discussion ranging from 10Base-T over twisted pair to Gigabit Ethernet cabling. Methods of optimising Ethernet to obtain best performance are then defined. Finally the all important topic of troubleshooting is examined with a summary of the typical problems you are likely to encounter from a two station network all the way up to a system comprising 30,000 PCs.

Filtering is an important mitigation technique for suppressing undesired conducted electromagnetic interference, when a system incorporates shielding, undesired coupling caused by radiated EMI is reduced. Conventional filter analysis and design assumes idealized and simplified conditions. These assumptions are not completely valid in many EMI filter because of unavoidable and severe impedance mismatch. Classical passive filter theory is well developed for communication circuits, where one can operate under impedance-matched conditions. Such filter characteristics are evaluated with 50Ω terminations. Filter evaluated with this procedure may behave differently when used in a circuit, where the impedance presented by the circuit to the filters is not exactly 50Ω. Now a day, digital signals are mostly used to avoid such EMI effects. These are caused by the capacitors, inductors, which are also part of the filtering circuits. Filter design using software, like MATLAB is very useful in avoiding hardware, is highly immune to noise and possesses considerable parameter stability, can be operated over a wide range of frequencies. The frequency response can be changed by changing the filter coefficients and can minimize the Insertion loses (IL).

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

III. INTRODUCTION
In this lab exercise you will design an antenna suitable for a 2G, 3G or
4G wireless application deployment. Such applications include 3G
cellular (e.g. CDMA2000 evolutions), IEEE 802.11x, IEEE 802.16 and
Bluetooth. The antenna should be deployable at a cellular base station,
cellular mobile unit, Bluetooth unit, a wireless LAN access point or
2. portable unit. IEEE 802.16 base station or portable device applications
can also be implemented.
IV.PROCEDURE
A. Resources
Well known classical antenna design procedures for various antenna
types are available from Internet resources and texts such as The ARRL
Antenna Book. Consult these resources as you proceed with your design
as this will not only expedite the process but assure that your chosen
design parameters meet with FCC specifications.
Refer to the FCC Part 15 documentation and other applicable documents
to make sure your design parameters meet the FCC stipulated limits.
The parameters of primary interest include: Operating Frequency,
Directivity, Radiation Pattern, and Gain. For any application for which
you choose to design, investigate the parameters as stipulated by the
FCC. You must include these applicable parameters in your report.
B. Antenna Choice
Work with your instructor to choose an antenna to design so that the
class develops a variety of solutions. Your report must support your
choice of antenna, that is, you must give the reasons why a particular
antenna type was chosen.
For example, for a cell phone, the antenna dimension, aesthetic beauty,
and omni-directivity may be the most important factors influencing your
design choice. However, for an antenna to be deployed at a cellular
base station, features such as directivity, wide operating bandwidth and
capability to radiate signals of relatively high power may be the primary
factors around which your design is centered. As you can see, you need
3. to consider technical aspects along with practicality when designing
your antenna. The following table should help in understanding your
choice.
