He's an optimist at heart. You'd like him. I, of course, don't know who you are, dear reader, but I know you'd like my dad, Bob Gruber, because everyone likes Bob Gruber. He can tell a good joke and he loves to tell them. There's a quote attributed to Abraham Lincoln, that I was reminded of, just the other day, from of all things a garbage can: "I don't like that man. I must get to know him better." I don't share Lincoln's there's-something-to-like-about-everyone optimism about our fellow men, but my dad does. from How It Went by John Gruber [Daring Fireball]

Finished Objects Daggers

The roll, pitch and yaw of an object relative to another is complex to compute. We use 3D complex number to compute them which makes the computation easier and more intuitive. Roll, pitch and yaw are angles of orientation of an object in space and the conversion of these angles among different reference frames is...

Starting from SPB23.1, a new option, Allow DRCs to surrounding metal, has been added in the Etch-Back form to allow DRCs to the surrounding objects. form to allow DRCs to the surrounding objects.

The Allow DRCs to surrounding metal option lets you see and adjust objects instead of the current behavior, which sacrifices the width of the mask for the trace.

• When this option is turned off, it maintains the EB mask to another object clearance.
• When this option is enabled, it keeps the EB mask to the EM trace edge clearance and shows a DRC if the EB mask to another object spacing is out of rule.

Believe it or not, levitating objects aren't just the stuff of science fiction and magic shows. There are actually many different forms of levitation including something called acoustic levitation, which uses powerful sound waves to trap objects in mid-air. WIRED spoke with a physicist at Argonne National Laboratory to find out how acoustic levitation works and what it's used for.

With London’s Victoria & Albert Museum in lockdown, its director shares his favourite artefacts

It is pretty dusty in South Kensington at the moment. Without millions of visitors wandering through the V&A galleries, the dust begins to settle and the past takes over. Under the steely eye of Vernon Rapley, head of security, our objects are resting safely at the moment. But the purpose of a museum is predicated upon dialogue and difference: the interaction between citizen and object, the journey into a web of histories, and then the flourishing of curiosity.

“Unvisited museums dwindle into very sleepy and useless institutions,” said our first director Henry Cole, who was an early proponent of blockbuster exhibitions.

During VR demos we have performed over last few years, many participants (in the absence of any haptic feedback) have commented on their perceived ability to 'feel' differences between simulated molecular objects. The mechanisms for such 'feeling' are not entirely clear: observing from outside VR, one can see that there is nothing physical for participants to 'feel'. Here we outline exploratory user studies designed to evaluate the extent to which participants can distinguish quantitative differences in the flexibility of VR-simulated molecular objects. The results suggest that an individual's capacity to detect differences in molecular flexibility is enhanced when they can interact with and manipulate the molecules, as opposed to merely observing the same interaction. Building on these results, we intend to carry out further studies investigating humans' ability to sense quantitative properties of VR simulations without haptic technology.

This paper investigates the convergence of the randomized Kaczmarz algorithm for the problem of phase retrieval of complex-valued objects. While this algorithm has been studied for the real-valued case}, its generalization to the complex-valued case is nontrivial and has been left as a conjecture. This paper establishes the connection between the convergence of the algorithm and the convexity of an objective function. Based on the connection, it demonstrates that when the sensing vectors are sampled uniformly from a unit sphere and the number of sensing vectors $m$ satisfies $m>O(nlog n)$ as $n, m ightarrowinfty$, then this algorithm with a good initialization achieves linear convergence to the solution with high probability.

In one embodiment, a plurality of objects associated with a dataset and a specified number of nearest objects to be identified are received. The received objects are sorted in a structured format. Further, a key object and a number of adjacent objects corresponding to the key object are selected from the sorted plurality of objects, wherein the number of adjacent objects is selected based on the specified number of nearest objects to be identified. Furthermore, distances between the key object and the number of adjacent objects are determined to identify the specified number of nearest objects, wherein the distances are determined until the specified number of nearest objects is identified. Based on the determined distances, the specified number of nearest objects in the dataset is identified for data analysis.

A data warehouse is constructed using the relational mapping of a transactional database without reconstructing the data relationships of the transactional database. First, an application programmer analyzes an object model in order to describe facts and dimensions using the objects, attributes, and paths of the object model. Each of the dimensions has an identifier that correlates an item in the transactional database to a dimension record in the data warehouse. The fact and dimension descriptions are saved to a description file. Second, a Data Warehouse Engine (DWE) then access the description file and uses the object model, fact and dimension descriptions, and object-relational mapping to map transactional data to the data warehouse.

Generally, compositions and methods of producing dimensionally stable three dimensional objects using an additive build up process. Specifically, materials combinable in an additive build up process using a materials printer for the production of stable three dimensional molds useful in the production of molded or formed parts.

A method and apparatus for the stabilization and safe removal of buried waste that is tested and classified as being transuranic or not transuranic waste and disposed accordingly. The buried waste (usually in vertical pipe units) is enclosed in a casing and ground and mixed with the surrounding soil. This process allows for chemical reactions to occur that stabilizes the mixture. The entire process is contained within the casing to avoid contamination. In situ or external testing is done for radio isotopes to classify the waste. If it is classified as transuranic the waste is removed in a controlled way into a retrieval enclosure and disposed off in drums. If the waste is not transuranic then grout is introduced into the mixture, allowed to set and the resulting monolith is removed and buried in trenches.

A method and apparatus for distributing objects. In one embodiment, the method comprises computing a modulus operand based on a number of objects to be distributed and a number of objects pertaining to a first category; computing a modulus operation based on a number of distributed objects and the modulus operand; and distributing a first object or a second object based on a result of computing the modulus operation.

An RF beam is used to probe the presence or absence of a rotating blade in a known field of view. Timing of appearance or disappearance or “zero-crossing” of a reflected signal is correlated with timing of the blade movement. Blades which are leading or lagging versus other blades will produce different timing signatures representative of alignment of the blades.
