The Weighted Least Squares Problem Sample Clauses

The Weighted Least Squares Problem. ‌ In Chapter 4, we have discussed energy-windowed spectral CT model and introduced a new preconditioner based on the corresponding nonlinear least squares problem and the Xxxxx-Xxxxxx approximation of the Hessian. A two-step optimization method that includes projected line search and trust region method is implemented to solve this problem. However, there are two main concerns related to the preconditioner and optimization. At first, the preconditioner requires the information of the current iteration and even if it is cheap to compute, we still need to repeat the computational process in each Xxxxxx iteration. Secondly, since the nonlinear optimization is based on the Xxxxx-Xxxxxx approximation of the Hessian, it raises a question if we can come up with a new preconditioner and use a first order method to solve it. In this chapter, we still focus on the energy-windowed spectral CT model and we present a linearization technique to transform the nonlinear equation into an optimization problem that is based on a weighted least squares term and a bound constraint. Recall that the basic energy-windowed spectral CT model is expressed by ∫ y(k) = S(k)(e) exp .− ∫ t∈l µ (˙r (t) , e) d tΣ d e + η(k).  i = 1, 2, · · · , Nd × Np,  k = 0, 0, · · · , Xx, X Using the material decomposition, µ (˙r (t) , e) = Nm um,ewm (˙r), discretizing Equation

  • STRS PICK-UP The Board agrees, as a condition of employment, to tax shelter employee contributions to the State Teacher's Retirement System (STRS) in accordance with State Retirement System and Federal Internal Revenue Service guidelines and restrictions. This section in no way implies that the Board will contribute any portion of the employee's share of retirement contributions. For purposes of this paragraph, total annual salary and salary per pay period of each bargaining unit member shall be the salary otherwise payable under this Agreement, as amended. The total annual salary and salary per pay period of each member shall be payable by the Board in two parts: (1) deferred salary and (2) cash salary. A member's deferred salary shall be equal to that percentage of said member's total annual salary or salary per pay period which is required from time to time by the State Teachers Retirement System (STRS) to be paid as an employee contribution by said member as a pickup of the STRS employee contribution otherwise payable by said member. A member's cash salary shall be equal to said member's total annual salary or salary per period less the amount of the pickup for said member and shall be payable, subject to applicable payroll deductions, to said member. The Board's total combined expenditures for members' total annual salaries otherwise payable under this Agreement, as amended, (including pickup amounts) and its employer contributions to STRS shall not be greater than the amounts it would have paid for those items had this provision not been in effect. The Board shall compute and remit its employer contributions to STRS based upon total annual salary, including the "pickup". The Board shall report for Federal and Ohio income tax purposes as a member's gross income said member's total annual salary less the amount of the "pickup". The Board shall report for municipal income tax purposes as a member's gross income said member's total annual salary, including the amount of the pickup. The pickup shall be included in the member's total annual salary for the purpose of computing daily rate of pay, for determining paid salary adjustments to be made due to absence, or for any other similar purpose. The pickup shall apply to all payroll payments made after the effective date of this provision. Should the Board's payment of deferred salary cause an individual bargaining unit member's annuity contributions to exceed the IRS permissible level, any such individual shall have the right to adjust annuity deductions within thirty (30) days of the effective date of this provision.

  • Spares/bunkers, etc The Sellers shall deliver the Vessel to the Buyers with everything belonging to her on board and on shore including all Owners’ supply items as per the Shipbuilding Contract. All spare parts and spare equipment including spare tail-end shaft(s) and/or spare propeller(s)/propeller blade(s), if any, belonging to the Vessel at the time of delivery used or unused, whether on board or not shall become the Buyers’ property, but spares on order are to be excluded. Forwarding charges, if any, shall be for the Buyers’ account. The Sellers are not required to replace spare parts including spare tail-end shaft(s) and spare propeller(s)/propeller blade(s) which are taken out of spare and used as replacement prior to delivery, but the replaced items shall be the property of the Buyers. The radio installation and navigational equipment shall be included in the sale without extra payment. Unused stores and provisions shall be included in the sale and be taken over by the Buyers without extra payment. The Sellers have the right to take ashore crockery, plates, cutlery, linen and other articles bearing the Sellers’ flag or name, provided they replace same with similar unmarked items. Library, forms, etc., exclusively for use in the Sellers’ vessel(s), shall be excluded without compensation. Captain’s, Officers’ and Crew’s personal belongings including the slop chest are to be excluded from the sale, as well as the following additional items (including items on hire): The Buyers shall take over the remaining bunkers and unused lubricating oils/greases on board at the time of delivery and pay the Sellers’ net price (excluding barging expenses) from the time of supply. Lubricating oils to be those in sealed drums and/or designated storage tanks not having been used or circulated in the vessel’s machinery. Payment under this Clause shall be made at the same time and place and in the same currency as the Purchase Price.

  • Innovative Unit Scheduling Schedules other than those included in Articles 13.01 and 13.02 may be developed in order to improve quality of working life, support continuity of patient care, ensure adequate staffing resources, and support cost-efficiency. The parties agree that such innovative schedules may be determined locally by the Hospital and the Union subject to the following principles: (a) Such schedules shall be established by mutual agreement of the Hospital and the Union; (b) These schedules may pertain to full-time and/or part-time nurses; (c) The introduction of such schedules and trial periods, if any, shall be determined by the local parties and recorded in the Appendix of Local Provisions. Such schedules may be discontinued by either party with notice as determined within the Appendix of Local Provisions; (d) Upon written agreement of the Hospital and the Union, the parties may agree to amend collective agreement provisions to accommodate any innovative unit schedules.

  • No Release; Return or Destruction Each Party agrees not to release or disclose, or permit to be released or disclosed, any information addressed in Section 6.9(a) to any other Person, except its Representatives who need to know such information in their capacities as such (who shall be advised of their obligations hereunder with respect to such information), and except in compliance with Section 6.10.
