A method comprising accessing a first data structure that is associated with a first product prepared by a student and that includes first process data associated with a process performed by the student in generating the first product, analyzing the first data structure to generate a first characterization score based on the first product and the first process data, accessing a second data structure that is associated with a second product prepared by the student and that includes second process data associated with a process performed by the student in generating the second product, analyzing the second data structure to generate a second characterization score based on the second product and the second process data, and calculating a skill level change metric based on the first characterization score and the second characterization score indicating a change in ability level of the student over a course of the scenario-based assessment.

可啟閉直流待機電源的電源供應器

本創作係一種可啟閉直流待機電源的電源供應器，係具有一切換式電源電路及一繼電器驅動電路。該切換式電源電路的交電流源輸入埠的一端係串接一繼電器的切換開關，並於該繼電器導通時，令該切換式電源電路係將交流電源轉換為一直流待機電源及至少一直流工作電源。而該繼電器驅動電路則控制該繼電器，並於連接本創作電源供應器的電腦關機時，使該繼電器的切換開關不導通，使該切換式電源電路不輸出該直流待機電源，直到該電腦開機瞬間，該繼電器驅動電路才使該繼電器的切換開關導通，以提供該電腦開機所需的直流待機電源。

Confident processing of valuations from distributed models systems and methods

Confidence-boosted automated valuation systems and methods for performing confident processing of valuations from automated valuation models are disclosed. The confidence-boosted automated valuation system uses home/model data, actual values, and predicted values of homes to train a confidence model to produce confidence scores. The system can partition the homes into confident bins each containing homes with similar confidence scores. To generate a confidence score for a predicted value of a subject home, the confidence-boosted automated valuation system can apply the trained confidence model to the subject home. Using the generated confidence score, the confidence-boosted automated valuation system can identify a confidence bin the subject home falls in. The confidence-boosted automated valuation system can compute a predicted error in the predicted value of the subject home using the confidence bin. Based on the predicted error, the confidence-boosted automated valuation system can determine whether the predicted value is a confident home value.

Three-section slide rail device

A three-section slide rail device includes an outer section, a middle section and an inner section. The middle section includes a middle rail slidably disposed on the outer section, a ball sliding plate slidably disposed on the middle rail, and a leaf spring at one end of the middle rail. The ball sliding plate has a plate body, a synchronizing block and a positioning hole formed on the plate body. The inner section includes an inner rail and a synchronizing actuating member pivotably mounted to the inner rail. The synchronizing actuating member is in an abutting engagement with the synchronizing block during an extended movement of the inner section relative to the middle section to make synchronizing movement of the ball sliding plate with the inner section until the positioning hole of the ball sliding plate is engaged with the leaf spring.

Three-section slide rail device

A three-section slide rail device includes an outer section, a middle section and an inner section. The middle section includes a middle rail and an inner middle block. The inner section includes an inner rail slidably disposed on the middle rail, and a removal operating assembly disposed on the inner rail. The removal operating assembly has a removal operating member, a removal connecting plate and a removal locking member pivotably mounted on the inner rail and having a removal guiding slot. The removal locking member has a locking portion and a protrusion. The removal operating member is operated to move the removal connecting plate and bring the protrusion to move along the removal guiding slot to result in pivoting of the removal locking member so as to disengage the locking portion from the inner middle block for permitting removal of the inner section from the middle section.

Three-section slide rail device

A three-section slide rail device includes an outer section, a middle section and an inner section. An outer rail of the outer section has a sliding surface and an anti-retraction block and a releasing block formed on the sliding surface. A middle rail of the middle section is slidably disposed on the outer rail. An anti-retraction member and a driven member are pivotably mounted on an end of the middle rail. An inner rail of the inner section is slidably disposed on the middle rail, and has an abutment plate and a driving plate formed on an inner surface of the inner rail. The abutment plate abuts upwardly against the anti-retraction member, and is moved to disengage from the anti-retraction member to permit abutment of the anti-retraction member against the anti-retraction block so as to prevent retraction movement of the middle section relative to the outer section.
