Standards and Specifications for Ground Processing of Space Vehicles: From an...John Ingalls
Proprietary or unique designs and operations are expected early in any industry's development, and often provide a competitive early market advantage. However, there comes a time when a product or industry requires standardization for the whole industry to advance...or survive. For the space industry, that time has come. Here, we will focus on standardization of ground processing for space vehicles and their ground systems.
To successfully grow the viability of the space industry, all members, commercial and government, will need to engage cooperatively in developing and applying standards to move toward interoperability. If we leverage and combine the best existing space standards and specifications, develop new ones to address known gaps, and adapt the best applicable features from other industries, we can establish an infrastructure to not only accelerate current development, but also build longevity for a more cohesive international space community.

The offshore wind industry has seen a dramatic increase in concern over the costs and practicalities of operations and maintenance (O&M). There are strategic and operational concerns in the market: Strategically, projects will find finance more accessible and affordable if they can demonstrate properly developed O&M policies and costings for their planned wind farms; operationally because people need to know what challenges they are likely to face throughout the wind farm lifetime.
However, while in broad terms the industry is aware of problems arising from unforeseen failures or costs, objective data related to costs and performance has been hard to obtain from multiple sites to provide reliable benchmarks for O&M performance and practices.
This international study brings together critical information and analysis in one clear and digestible report; providing much-needed information on O&M costs, practices, cost drivers and the future evolution of O&M. This provides concrete information for the first time to the whole offshore wind industry including policy setters, R&D organisations, investors and manufacturers as well as wind farm operators and developers.
Because of the confidential nature of the source data, some information is presented as averages, aggregates or in an anonymised fashion. However, this provides the only comprehensive and coherent opportunity to benchmark O&M activities, costs and performance against the rest of the industry.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Embracing GenAI - A Strategic ImperativePeter 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

I. SCOPE
The waterflow alarm indicator with instantly recycling retard is used in a wet pipe sprinkler system to sound an
electrical alarm when one or more sprinklers operate.
FM Approval is based on examination and tests of production samples, inspection of the manufacturing or
quality control facilities, and satisfactory field experience. Particularly considered are functional suitability,
adequacy of design and workmanship, uniformity and dependability of production, effectiveness of quality
control, and assurance of service and replacement parts.
These requirements are guides. Mere conformity does not assure approval; other considerations may control. Nor
is strict conformity necessary; devices having different characteristics may be considered and approved, if shown
to be essentially equivalent or superior in performance.
om
.c
II. GLOSSARY
a se
The waterflow alarm indicator is made up of the vane, body, switch, and instantly recycling retard.
gb
A. Vane
in
in
The submersible vane is moved by the water flow. The movement is transmitted through suitable levers to open
or close switch contacts.
tra
B. Body
re
.fi
The body’s primary functions are to:
1. Provide support for levers between the vane and the switch.
w
2. Permit strapping the indicator to the pipe.
w
3. Provide a support for the switch.
w
C. Instantly Recycling Retard
This device operates, after a predetermined time has elapsed from the initial movement of the vane, to sound the
alarm.
1. There shall be no mechanical failure nor any appreciable change in the operating characteristics as a result
of this test.
2. The vane assembly shall be subjected to the following forward flow rates for 30 minutes.

2. Performance
tra
The retard shall be these characteristics:
re
a. When the initial water flow occurs, the retard shall operate to delay the electric alarm for any pre-
selected period of 0-60 seconds. While an adjustable time delay of 0-60 seconds is preferable, a time delay
.fi
having a maximum limit of 120 seconds will be acceptable. Suitable instructions indicating means for
increasing or decreasing the retard shall be provided.
w
b. In the event the water flow ceases before the completion of the pre-selected time delay, the retard shall
w
automatically reset in such a manner that the entire retard cycle must be repeated when water flow again
w
occurs.
c. Contacts shall be arranged to permit operation on either open or closed circuits.

III. REQUIREMENTS
A. Performance
Waterflow alarm indicators shall be so designed that they may be installed in either horizontal or vertical pipe
and that after proper initial factory adjustment they will:
1. Operate at a rate of flow between 4 and 20 gpm at any service pressure between 20-100 psig.
2. Operate on any flow rate in excess of minimum flow to give alarm.
3. Not operate at flows less than 4.0 gpm.
5. Transmit successive alarms without manual resetting.

C. Vane Assembly
w
w
Vane assemblies shall have sufficient mechanical strength to resist flows created by fluctuating water pressures
and operation of several sprinklers.
w
To evaluate the design, a sample 6 in. indicator—considered representative of the line—shall be subjected to the
following tests:
1. The vane assembly will be subjected to 100,000 flexes. A single flex involves moving the van in the
forward direction through an angle of 45° from its ‘‘normal’’ position (at zero flow) and then permitting
it to return to ‘‘normal’’. Rate of flexes shall be approximately 18-20 per minute.
A rubber faced roller (approximately O.D. of 3 in.) connected to the end of an air powered oscillating rod
will be arranged to strike the vane at its center when it is in the ‘‘normal’’ position. The roller moves at
all times in a direction perpendicular to the plane of the vane when in its ‘‘normal’’ position.
FM APPROVALS 3
7. 1042 July 1970
E. Rated Working Pressure
Indicators shall be designed for a rated working pressure of 175 psi.
To determine design adequacy, a 6 in. sample will be hydrostatically tested at 700 psi for five minutes. There
shall be no failure as a result of this test.
F. Assembly
Indicators shall be designed so that when installed the vane will always be at right angles to the water flow.
Whenever practical, the use of asymmetrical parts shall be employed.
om
G. Wiring Diagrams
Schematic electrical wiring diagrams shall be attached to the inside cover of each indicator.
