We provide a dynamical perspective on the classical problem of 3D point cloud registration with correspondences. A point cloud is considered as a rigid body consisting of particles. The problem of registering two point clouds is formulated as a dynamical system, where the dynamic model point cloud translates and rotates in a viscous environment towards the static scene point cloud, under forces and torques induced by virtual springs placed between each pair of corresponding points. We first show that the potential energy of the system recovers the objective function of the maximum likelihood estimation. We then adopt Lyapunov analysis, particularly the invariant set theorem, to analyze the rigid body dynamics and show that the system globally asymptotically tends towards the set of equilibrium points, where the globally optimal registration solution lies in. We conjecture that, besides the globally optimal equilibrium point, the system has either three or infinite "spurious" equilibrium points, and these spurious equilibria are all locally unstable. The case of three spurious equilibria corresponds to generic shape of the point cloud, while the case of infinite spurious equilibria happens when the point cloud exhibits symmetry. Therefore, simulating the dynamics with random perturbations guarantees to obtain the globally optimal registration solution. Numerical experiments support our analysis and conjecture.

With the growing reliance on the ubiquitous availability of IT systems and services, these systems become more global, scaled, and complex to operate. To maintain business viability, IT service providers must put in place reliable and cost efficient operations support. Artificial Intelligence for IT Operations (AIOps) is a promising technology for alleviating operational complexity of IT systems and services. AIOps platforms utilize big data, machine learning and other advanced analytics technologies to enhance IT operations with proactive actionable dynamic insight.

In this paper we share our experience applying the AIOps approach to a production cloud object storage service to get actionable insights into system's behavior and health. We describe a real-life production cloud scale service and its operational data, present the AIOps platform we have created, and show how it has helped us resolving operational pain points.

A cloud system may create physical resource tags to store relationships between cloud computing offerings, such as computing service offerings, storage offerings, and network offerings, and the specific physical resources in the cloud computing environment. Cloud computing offerings may be presented to cloud customers, the offerings corresponding to various combinations of computing services, storage, networking, and other hardware or software resources. After a customer selects one or more cloud computing offerings, a cloud resource manager or other component within the cloud infrastructure may retrieve a set of tags and determine a set of physical hardware resources associated with the selected offerings. The physical hardware resources associated with the selected offerings may be subsequently used to provision and create the new virtual machine and its operating environment.

A server computer system determines that configuring a first virtual machine in a cloud depends on a configuration result of configuring a second virtual machine. The server computer system configures the second virtual machine in the cloud and configures the first virtual machine in the cloud using the configuration result of the second virtual machine.

The logistic operation can include one or more of object location, object identification, object picking, object picking by line, object loading onto one or more transport devices, and object delivery.

A communication system for communicating with at least one loudspeaker is described where the loudspeaker is connected to audio equipment over standard two-wire speaker wire operable to carry an audio signal. The communication system includes a master node in electrical communication with a signal path carrying the audio signal between the audio equipment and the loudspeaker, the master node also including an interface with the audio equipment, a data encoder operable to encode data signals, a data transceiver operable to place the data signals onto the audio signal at frequencies above audio frequencies. The communication system also includes at least one slave node in electrical communication with the audio signal and each loudspeaker, the slave node including a data transceiver operable to receive data signals from the master node, a data decoder, and an interface able to communicate with the loudspeaker.

The invention relates to a loudspeaker mounting and adjustment system and method for installing and operating a professional audio system used in a stadium, concert hall or the like. The system comprises a vertical array of loudspeaker cabinets that can be suspended from a ceiling and that enables the horizontal and vertical angle of the sound dispersion field to be adjusted remotely and/or automatically while the system is suspended. Each loudspeaker cabinet is connected to a vertically adjacent loudspeaker cabinet via a pair of levers located on either side of the cabinet that control the angle between adjacent loudspeaker cabinets. A linear actuator is connected to each lever for controlling the lever position. Each loudspeaker cabinet also comprises a waveguide with at least one actuator for modifying the waveguide angle and thus the horizontal angle of the sound dispersion field.

A connection device for setting up an arrangement of a plurality of loudspeaker boxes that are suspended beneath one another comprises a first assembly rail which is provided for assembly on a first loudspeaker box and to which a latching part is attached, and a second assembly rail which is provided for assembly on a second loudspeaker box and to which a retaining element that interacts with the latching part is attached. Herein, a free path length of a longitudinal displaceability of the latching part in relation to the first assembly rail is preselectable. Furthermore, the position of the retaining element in relation to the second assembly rail is preselectable.

Networking systems and methods for establishing and maintaining virtual computing clouds are disclosed. A networking system can comprise a server and various instances of a software agent, each agent being installed on a computing device participating in a virtual computing cloud. The server can maintain account setting for a user, wherein the settings can indicate which files on indicated computing devices are included in the virtual computing cloud. The networking system can selectively synchronize data between the computing devices automatically and in a secure manner, and can transmit data in real time to simulate local storage when synchronization of certain files is inappropriate in light of file incompatibility. As a result, the networking system can provide the user with a seamless, automatic system and method for accessing a total computing environment.

I believe in b lack c louds. My official job title while I was i n the Marine Corps was “ Crewmaster .” That means I was an enlisted aircrew member who took part in logistics and combat support missions on the Marine Corps’ largest aircraft , the C-130 , also known as the “Super Hercules.” I could spend hours describing the various aspects of my job, but in summary the Crewmaster is responsible for nearly all aspects of aviation on the Super Hercules, short of actually flying the plane. The community of Marine Aviators, including Pilots and Aircrewmen, is tight knit. Every body knows every body , and m any of us receive a nickname, or what we refer to as “ c all s igns.” My call sign was Black Cloud ; a nickname I received because nearly every time I set foot on an airplane, something went wrong. Usually, these were relatively minor issues, such as erroneous alert messages or radios that weren’t working properly. But sometimes I brought bad luck in more serious ways. On ce , a liquid

Updated at 6:12 p.m. ET Andy Serkis, the physically nimble actor largely known for his CGI-assisted roles, did some quarantine reading, performing the entirety of The Hobbit in a livestream on Friday. On a Gofundme page established for the event, Serkis wrote that he would conduct the 12-hour marathon reading of J.R.R. Tolkien's beloved fantasy novel to raise funds for COVID-19 relief efforts. Depending on his copy, that's some 300 pages of Bilbo Baggins' adventure from his humble hobbit hole in the Shire to the mountain lair of the fearsome dragon Smaug – and back again, read and performed by Serkis. The actor began reading the novel at around 10 a.m. in the United Kingdom (that's 5 a.m. ET). "Together we'll face the might of the trolls, journey to the magical Rivendell, encounter the giant spiders in the labyrinths of Mirkwood, and the evil goblins living among the roots of the Misty Mountains, until we meet the dragon Smaug, and see the Battle of the Five Armies," Serkis wrote on

Businesses can make IT operations smarter by reacting to weather events and automating operational decisions that factor in weather data. This article describes the steps to combine services to automate decisions that consider weather data by running business rules. The business decisions could result in actions such as sending notifications, adjusting prices, generating promotions, triggering IoT devices, or initiating business processes.

In this Top 10 List, Carl Osipov shares his views on why developers will want to choose IBM Cloud as their cloud platform of choice.

The cloud is not secure. Developers know through experience that software and servers get hacked thanks to bad code and insecure Internet connections to remote servers and data centers. You can compare using the cloud to having valuables that are locked up in a suitcase in a parking lot. By nature, both are susceptible to attacks. In this article, we explain the reasons why the cloud is not secure, but we also examine ways to mitigate any insecurities by illustrating some Django examples through the inception of BugHeist.
