Suspended ▇▇▇▇▇▇▇▇▇ junction arrays Clause Samples

Suspended ▇▇▇▇▇▇▇▇▇ junction arrays. A circuit element can be considered as a superinductor if it displays a very large inductance and a minimal capacitive component. So far, efforts focused mainly on boosting the former by replacing conventional superconducting wires by ▇▇▇▇▇▇▇▇▇ junction arrays or disordered superconducting stripes. Little was done to minimize stray capacitances. However, most of the superconducting quantum devices are fabricated on silicon or sapphire, and present a high dielectric constant. With SiUCs we will develop a new technology: ▇▇▇▇▇▇▇▇▇ junction arrays patterned on very thin (~200nm) suspended silicon membranes. The electric field both above and below the device will then be mainly in vacuum. This configuration will therefore reduce the effective dielectric constant seen by the array down to one, while it is approximately six otherwise (this number comes from the widely used approximation in microwave engineering: εtotal = 1/ 2(ε + εbottom )= 1/ 2(1+10) ≈ 6), reducing the stray capacitance by the same amount. To obtain such suspended arrays, we will fabricate them by standard methods but using Silicon-On-Insulator substrates. Then the insulator (silicon oxide) will be etched away using hydrofluoric acid vapour. This technique was successfully employed to fabricate electromechanical systems compatible with qubits [Keller2017]. The same technique can also be used to reduce the parasitic capacitance of granular aluminium superinductors.

  • Unbundled Loop Modifications (Line Conditioning 2.5.1 Line Conditioning is defined as routine network modification that BellSouth regularly undertakes to provide xDSL services to its own customers. This may include the removal of any device, from a copper Loop or copper Subloop that may diminish the capability of the Loop or Subloop to deliver high-speed switched wireline telecommunications capability, including xDSL service. Such devices include, load coils, excessive bridged taps, low pass filters, and range extenders. Excessive bridged taps are bridged taps that serves no network design purpose and that are beyond the limits set according to industry standards and/or the BellSouth’s TR 73600 Unbundled Local Loop Technical Specification. 2.5.2 BellSouth will remove load coils only on copper Loops and Subloops that are less than eighteen thousand (18,000) feet in length. 2.5.3 For any copper loop being ordered by NewPhone which has over six thousand (6,000) feet of combined bridged tap will be modified, upon request from NewPhone, so that the loop will have a maximum of six thousand (6,000) feet of bridged tap. This modification will be performed at no additional charge to NewPhone. Loop conditioning orders that require the removal of bridged tap that serves no network design purpose on a copper Loop that will result in a combined total of bridged tap between two thousand five hundred (2,500) and six thousand (6,000) feet will be performed at the rates set forth in Exhibit A. 2.5.4 NewPhone may request removal of any unnecessary and non-excessive bridged tap (bridged tap between zero (0) and two thousand five hundred (2,500) feet which serves no network design purpose), at rates pursuant to BellSouth’s SC Process as mutually agreed to by the Parties. 2.5.5 Rates for ULM are as set forth in Exhibit A. 2.5.6 BellSouth will not modify a Loop in such a way that it no longer meets the technical parameters of the original Loop type (e.g., voice grade, ADSL, etc.) being ordered. 2.5.7 If NewPhone requests ULM on a reserved facility for a new Loop order, BellSouth may perform a pair change and provision a different Loop facility in lieu of the reserved facility with ULM if feasible. The Loop provisioned will meet or exceed specifications of the requested Loop facility as modified. NewPhone will not be charged for ULM if a different Loop is provisioned. For Loops that require a DLR or its equivalent, BellSouth will provide LMU detail of the Loop provisioned. 2.5.8 NewPhone shall request Loop make up information pursuant to this Attachment prior to submitting a service inquiry and/or a LSR for the Loop type that NewPhone desires BellSouth to condition. 2.5.9 When requesting ULM for a Loop that BellSouth has previously provisioned for NewPhone, NewPhone will submit a SI to BellSouth. If a spare Loop facility that meets the Loop modification specifications requested by NewPhone is available at the location for which the ULM was requested, NewPhone will have the option to change the Loop facility to the qualifying spare facility rather than to provide ULM. In the event that BellSouth changes the Loop facility in lieu of providing ULM, NewPhone will not be charged for ULM but will only be charged the service order charges for submitting an order.

  • Loop Provisioning Involving Integrated Digital Loop Carriers 2.6.1 Where Freedom has requested an Unbundled Loop and BellSouth uses IDLC systems to provide the local service to the End User and BellSouth has a suitable alternate facility available, BellSouth will make such alternative facilities available to Freedom. If a suitable alternative facility is not available, then to the extent it is technically feasible, BellSouth will implement one of the following alternative arrangements for Freedom (e.g. hairpinning): 1. Roll the circuit(s) from the IDLC to any spare copper that exists to the customer premises. 2. Roll the circuit(s) from the IDLC to an existing DLC that is not integrated. 3. If capacity exists, provide "side-door" porting through the switch. 4. If capacity exists, provide "Digital Access Cross Connect System (DACS)- door" porting (if the IDLC routes through a DACS prior to integration into the switch). 2.6.2 Arrangements 3 and 4 above require the use of a designed circuit. Therefore, non- designed Loops such as the SL1 voice grade and UCL-ND may not be ordered in these cases. 2.6.3 If no alternate facility is available, and upon request from Freedom, and if agreed to by both Parties, BellSouth may utilize its Special Construction (SC) process to determine the additional costs required to provision facilities. Freedom will then have the option of paying the one-time SC rates to place the Loop.

  • Unbundled Digital Loops 2.3.1 BellSouth will offer UDLs. UDLs are service specific, will be designed, will be provisioned with test points (where appropriate), and will come standard with OC and a DLR. The various UDLs are intended to support a specific digital transmission scheme or service. 2.3.2 BellSouth shall make available the following UDLs, subject to restrictions set forth herein:

  • Mentor Program a. Each new Bargaining Unit Member (first year employee) shall be assigned a mentor. An exception may be made, as determined by the Superintendent, for new part-time Bargaining unit Members of whom have prior service in the same program operated by the Board. The mentor shall assist the new Bargaining Unit Member in general teaching procedures, techniques, classroom planning and organization, school functions and regulations and other areas of professional growth and development. The Association President in collaboration with the Lead Mentor/Resident Educator Coordinator and appropriate Directors shall submit nominations of three (3) qualified staff members to the Superintendent, after obtaining the candidates’ permission. The Superintendent may elect to nominate one of the candidates to the Board of Education for assignment, or ask the Association President and Lead Mentor/Resident Educator Coordinator for additional nominations. b. No mentor shall be assigned more than one new Bargaining Unit Member per year. The mentor shall not be involved in any way in the formal evaluation of the new Bargaining Unit Member, but shall confer with the assigned Supervisor on the strengths and weaknesses of the new unit member and his or her overall performance and progress. In order to be assigned, mentors must possess the following qualifications: i. At least two (2) years of successful teaching experience at Tolles. ii. A variety of teaching experience. iii. An ability and willingness to help improve another teacher. c. Mentors shall attend one or two (2) training seminars held outside the regular workday. The Association President in collaboration with the Lead Mentor/Resident Educator Coordinator and appropriate Directors will draft a list of tasks which mentors are to perform. d. Mentor teachers shall certify that they have spent a minimum of 15 hours during the school year in mentor training and working with their assigned new Bargaining Unit Member. The new Bargaining Unit Member may make written application to the Superintendent for up to 15 hours additional mentor service. The mentor teacher, the new Bargaining Unit Member, and the Superintendent or Superintendent’s designee, will meet to discuss a plan of action for additional hours requested. Mentor teachers shall be paid for the documented work hours at the hourly rate of $30. The payment shall be in a one-time lump sum at the end of the school year. e. If there are teachers who are new to the District, the Lead Mentor will receive two (2) days extended time to work with new teachers and the administration before the regular instructional year for the purpose of training new staff members in the successful use of the teacher handbook, school regulations, and operational procedures.
