Example embodiments provide a system and a method for fault monitoring of an electrical system for airfield ground lighting. The method comprises monitoring current changes occurring in a lighting circuit 308 of the electrical system with a plurality of measurement devices 200 installed to monitor the current without being part of the lighting circuit 308. The method further comprises detecting an indication of a fault in the lighting circuit 308 and a location of the fault based on the current measurements received from the measurement devices 200.

An arrangement for bringing an elevator car to safety at a faster speed. The arrangement comprises high-speed and slow-speed zones. When the elevator car is located at a slow-speed zone, a standard rescue speed is used. When the elevator is located at a high-speed zone, a faster operating speed is used. The speed zones are indicated inside the elevator shaft in a machine-readable manner.

The proposed solution provides a wall panel (1,1a,1b) for holding building blocks (2). The wall panel (1,1a,1b) comprises a front face (3), a back face (4), grippers (5) projecting forward (F) from the front face (3), stretched parts (7) projecting backward (B) from the back face (4) and comprising a hole (17) for inserting fastener (11) therein, rows (8) comprising the grippers (5) and the stretched parts (7) placed next to each other, and channels (12) located at least one of the following: above, below, and/or between the rows (8), and configured to receive the building blocks (2). The stretched parts (7) are located in the rows (8) so that when the channels (12) are configured to receive the building blocks (2), at least one corner (9) of the building blocks (2) is located next to at least one stretched part. Further, a wall element (10,10a,10b), a wall system (20), and a method is disclosed.

Dynamic control of prefetching based on prefetching accuracy in a computing system, and related methods and computer readable media. The computing system comprises a processor that includes one or more Central Processing Unit (CPU) cores each having an associated cache memory. The CPU core(s) is configured to generate a value indicative of a prefetching accuracy of the CPU core for prefetching of data, instructions, or both data and instructions from system memory external to the processor for storage in the cache memory for the CPU core and control the prefetching performed by the CPU core based on the value indicative of the prefetching accuracy. In this manner, the number of memory access requests for prefetching is reduced when prefetching accuracy is below a certain threshold, which in turn mitigates memory bandwidth contention, particularly in a multi-CPU core processor.

An acoustic surface element of a clean room, which element comprises a frame (10), a sound absorbing element (20) and a foil (30),wherein the frame comprises- a bottom panel (11) comprising at least one opening (12), and- side panels (13), which side panels are perpendicular to the bottom panel and the side panels are configured to form the perimeter of the acoustic surface element;whereinthe foil (30) is tensioned to cover the bottom panel having the at least one opening and at least partly the side panels of the frame.

A gripper arrangement (100), a method and a computer-readable medium. The arrangement comprises a suction gripper (1), comprising plurality of suction cups (2) arranged in a matrix-like order, and a control system (3) configured to detect the contour of the object (A) to be gripped, determine the centroid (C)of said object, define the positions (P) of the suction cups (2) around the centroid (C) of said object, determine a sub-set of suction cups of said plurality of suction cups (2) to be actuated for suction based on defined positions of the suction cups on the object and a predefined comparison task, guide the suction gripper (1) on the object (A) such that the suction cups (2) are on the defined positions (P), and actuate the suction cups (2) belonging to said sub-set of suction cups for suction.
