(1) A broad category of business processes that are modeled as objects. A business object can be as large as an entire order processing system or a small process within an information system. See object-oriented programming.

(2) (Business Objects) A San Jose-based company acquired by SAP in 2007 for its leadership in business intelligence and decision support tools. Business Objects was founded in France in 1990 by Bernard Liautaud and Denis Payre and was the first to integrate query, reporting and OLAP into one product that shields users from the complexities of making a query. In this context, the word "objects" does not refer to object-oriented programming as in definition #1 above, but to "business items." See SAP.

BusinessObjects (One Word)

Business Objects' products were always branded as one word and fall under the SAP BusinessObjects umbrella. Its flagship software is a suite of query, reporting and analysis tools that runs under Windows and Unix. It provides access to a wide variety of databases, including Oracle, INFORMIX and DB2. As data are extracted from the database, they are stored as multidimensional OLAP cubes that can be easily sliced and diced into different views. See OLAP.

The Semantic Layer

BusinessObjects uses a patented semantic layer that shields users from the complexities of table names and relationships. Once the semantic layer has been defined, users work with familiar "business objects" such as product, customer and revenue.

A BusinessObjects Query To perform a query, users drag and drop the object icons into the "Results" and "Conditions" windows. (Image courtesy of SAP.) Slicing and Dicing The Slice and Dice Panel can rearrange the view. After dragging and dropping different icons, BusinessObjects displays the new perspective. "Section" shows the sequence and report titles, and "Block Structure" shows the data wanted in the report. (Image courtesy of SAP.)

Killexams : Suppressing Object Printing in InDesign

Whether you're a professional graphic designer or a business owner who uses Adobe InDesign to produce in-house documents, you may use InDesign objects to add notes or experiment with alternative approaches to a design problem. When you're ready to print your document, you can suppress the output of your private editing notes or layout experiments without deleting them. Likewise, you can print a quick proofreader's copy of your layout when all you want to examine is its text.

Individual Objects

  1. Open the Window menu, locate its Output submenu and choose "Attributes" to reveal the Attributes panel if it isn't already visible. The panel's short height makes it easy to hide behind other taller panels, so if you see a check mark in front of its menu item but don't see the panel on your screen, hide it and bring it up again to locate it.

  2. Activate the Selection tool in the Adobe InDesign toolbox. Click on an item you want to designate as a non-printing object. Shift-click to select other items, or draw a marquee around several objects to select more than one at a time.

  3. Turn on the "Nonprinting" option in the Attributes panel. This suppresses the item's output when you print.


  1. Open the Window menu and choose "Layers" to reveal the Layers panel. Double-click on the listing for the layer whose objects you want to suppress at print time. You also can open the fly-out menu at the top-right corner of the panel and choose "Layer Options for [Layer name]," where "Layer name" represents the name of your layer.

  2. Uncheck "Print Layer" in the Layer Options dialog box. Once you deselect this option, nothing on the layer prints.

  3. Open the File menu and choose "Print" to bring up the Print dialog box. Enter the page range and number of copies you want to print. Click on the "Print" button to send your output to a printing device. If you're directing your output to a PDF file, you'll see a "Save" button instead of a "Print" button.


  1. Open the File menu and choose "Print" to bring up the Print dialog box. Click on the "Graphics" category in the list of print settings at the left side of the dialog box.

  2. Click on the "Send Data" drop-down menu and choose "None." This setting temporarily treats all your images as nonprinting.

  3. Select the "General" category in the list of print settings. Enter your desired page range and number of copies, then click on the "Print" button to generate your printout.

  4. Examine your output. You'll see frames with crossbar symbols instead of your images, but the frames accurately represent the size of your graphics and preserve their clipping paths, so their effect on your text appears.

Killexams : A model that could Strengthen robots' ability to grasp objects

When completing missions and tasks in the real-world, robots should ideally be able to effectively grasp objects of various shapes and compositions. So far, however, most robots can only grasp specific types of objects.

Researchers at the Chinese Academy of Sciences and Peking University have recently developed a new machine learning model that could help to enhance the grasping abilities of robots. This model, presented in IEEE Transactions on Circuits and Systems for Video Technology, is specifically designed to predict grasps for objects in a robot's surroundings, so that they can devise optimal strategies for grasping these objects.

"In real-world applications, such as intelligent manufacturing, human-machine interaction and domestic services, robotic grasping is becoming more and more essential," Junzhi Yu, one of the researchers who carried out the study, told Tech Xplore. "Grasp detection, a critical step of robotic grasping, entails finding the best grasp for a target object. Mainstream encoder-decoder grasp detection solutions are attractive in terms of accuracy and efficiency, yet they are still limited, due to the checkerboard artifacts from uneven overlap of convolution results in the decoder. Moreover, feature representation is often insufficient."

The key objective of the accurate work by Yu and his colleagues was develop a model that would overcome the limitations of existing grasp detection frameworks. To do this, they created a pixel-wise grasp detection method based on twin deconvolution and multi-dimensional attention, two established techniques often used for computer vision applications.

A model that could  Strengthen robots' ability to grasp objects
Structure of a twin deconvolution. F_in∈R^(c_in×h_in×w_in ) and F_out∈R^(C_out 〖×H〗_out×W_out ) denote the input feature map and output feature map, respectively, where c_in,h_in,w_in and C_out,H_out,W_out are the channel number, height, and width corresponding to F_in and F_out. There are two branches in a twin deconvolution: original branch and twin branch, where the former is a standard transposed convolution and the latter is used to calculate the overlap degree corresponding to the original branch for removing checkerboard artifacts. The input of twin branch is a matrix Ones∈R^(1×h_in×w_in ) with all the entries 1, whose spatial size is the same as that of the input feature map F_in of the original branch. Moreover, the kernel of the twin branch has the same spatial size as that of the original branch (K_h×K_w) and its all entries are set to 1⁄m, m=K_h×K_w. With the transposed convolution in the twin branch, the overlap degree matrix M_w∈R^(1×H_out×W_out ) is computed corresponding to all spatial positions of the output F_t∈R^(c_in×H_out×W_out ) from the original branch. Then, an element-wise division operation is performed between each channel of F_t and M_w. Followed by a pointwise convolution Conv1×1, the final output F_out of twin deconvolution is obtained. Credit: Ren et al

Their method was designed to eliminate so-called "checkerboard artifacts," strange checkerboard-like patterns that are often observed in images generated by artificial neural networks. In addition, the researchers strengthened their model's ability to refine specific features in images.

"The proposed pixel-wise grasp detection network is composed of an encoder, a multi-dimensional attention bottleneck, and a twin deconvolution-based decoder," Yu explained. "Given an input image, feature extraction is performed through the encoder and the obtained feature map is further refined through our bottleneck module, which integrates residual multi-head self-attention (R-MHSA), cross-amplitude attention (CAA), and raw compensation to better focus on the regions of interest."

The three components of the team's bottleneck module result in three different outputs that are concatenated in channel and further adjusted to Strengthen the representation of features. The resulting, refined "feature map" is then fed to the model's decoder (i.e., a model that up-samples the feature map into a desirable output). This decoder ultimately predicts the grasps that correspond to the input image, by performing three so-called cascaded twin deconvolutions (processes to up-sample the feature map).

"Through our bottleneck module, the intrinsic relationship between features is mined and features are effectively fine-tuned from the dimensions of spatial and channel," Yu said. "Particularly, the introduction of twin deconvolution provides better up-sampling by adding a twin branch upon original transposed convolution branch. As a result, the challenge of checkerboard artifacts is solved."

A notable advantage of the method developed by the researchers is its use of twin deconvolutions, through which a twin branch is introduced to the original transposed convolution branch, improving the model's original output. This approach allows the model to remove undesirable checkerboard patterns from outputs.

"It should be noted that the checkerboard artifacts originate from the uneven overlap of convolution results at different positions," Yu said. "Herein, a twin branch is introduced in parallel upon the original transposed convolution branch to measure the uneven overlap. More specifically, the twin branch computes the relative overlap differences among positions and the resultant overlap degree matrix is utilized to re-weight the feature map of original transposed convolution."

In initial tests, the new pixel-wise grasp detection method achieved very promising results, as it was found to smoothen the model's original output and eliminate checkerboard artifacts. It thus achieved a high grasp detection accuracy.

As part of their study, Yu and his colleagues were also able to extend their approach to other task that entail pixel-wise detection. In addition to potentially enhancing the grasping skills of both existing and newly developed robots, their model could thus soon be applied to other computer vision problems.

"In our next works, we plan to combine the proposed method with instance segmentation in genuine systems for better grasp prediction," Yu added. "For example, instance segmentation can be used to generate valuable information about object profile and position, which is fed into twin deconvolutions of the decoder to further Strengthen the network performance."

Killexams : The World's First Nuclear Bomb Test Forged a Strange Object

In July 1945, the US Army conducted the first ever nuclear bomb test in New Mexico, called "Trinity." The prototype weapon of mass destruction, known as "Gadget," exploded and released energy equivalent to about 21 kilotons of TNT.

In the 1980s, scientists discovered that the nuclear explosion inadvertently created an entirely new material. Surrounding sand, a 90 foot tower, and copper transmission lines were fused together to form a glass-like material called trinitite.

Inside this trinitite, scientists discovered a rare form of matter called a "quasicrystal." Rather than the atoms being arranged in a pattern that repeats itself in all three dimensions, as is the case in ordinary crystals found in nature, quasicrystals have atoms that aren't arranged in a periodic pattern.

Some of the trinitite that was formed in the 1945 explosion has a 5-fold rotational symmetry, meaning that atoms are arranged to form the shape of a 20-sided solid called an icosahedron.

This highly unusual symmetry, which is not possible in nature, was outlined in a new paper to be published in an upcoming issue of the journal Proceedings of the National Academy of Science.

The research could shed light on what exactly unfurls during nuclear bomb detonations and how they affect the natural surroundings.

"Here, we report the discovery, in a trial of red trinitite, of a hitherto unknown composition of icosahedral quasicrystal, Si61Cu30Ca7Fe2," the international team of researchers wrote in their paper. "It represents the oldest extant anthropogenic quasicrystal currently known, with the distinctive property that its precise time of creation is indelibly etched in history."

"Quasicrystals are formed in extreme environments that rarely exist on Earth,” said Terry Wallace, director emeritus of Los Alamos National Laboratory and co-author of the paper, in a statement.

"They require a traumatic event with extreme shock, temperature, and pressure," he added. "We don’t typically see that, except in something as dramatic as a nuclear explosion."

The only comparable material found in nature, the researchers say, is a meteorite that dates back at least hundreds of millions of years.

"This quasicrystal is magnificent in its complexity — but nobody can yet tell us why it was formed in this way," Wallace explained.

"But someday, a scientist or engineer is going to figure that out and the scales will be lifted from our eyes and we will have a thermodynamic explanation for its creation," he added. "Then, I hope, we can use that knowledge to better understand nuclear explosions and ultimately lead to a more complete picture of what a nuclear test represents."

Killexams : What’s Going On Up There? Theories but No Answers in Shootdowns of Mystery Craft.

WASHINGTON — If the truth is out there, it certainly is not apparent yet.

Pentagon and intelligence officials are trying to make sense of three unidentified flying objects over Alaska, Canada and Michigan that U.S. fighter jets shot down with missiles on Friday, Saturday and Sunday.

The latest turn in the aerial show taking place in the skies above North America comes after a helter-skelter weekend involving what at times seemed like an invasion of unidentified flying objects.

The latest object had first been spotted on Saturday over Montana, initially sparking debate over whether it even existed. On Saturday, military officials detected a radar blip over Montana, which then disappeared, leading them to conclude it was an anomaly. Then a blip appeared Sunday over Montana, then Wisconsin and Michigan. Once military officials obtained visual confirmation, they ordered an F-16 to shoot it down over Lake Huron.

There are two big questions around the episodes: What were the craft? And why does the United States appear to be seeing more suddenly, and shooting down more?

There are no answers to the first question yet. American officials do not know what the objects were, much less their purpose or who sent them.

For the second, it is not clear if there are suddenly more objects. But what is certain is that in the wake of the accurate incursion by a Chinese spy balloon, the U.S. and Canadian militaries are hypervigilant in flagging some objects that might previously have been allowed to pass.

After the transit of the spy balloon this month, the North American Aerospace Defense Command, or NORAD, adjusted its radar system to make it more sensitive. As a result, the number of objects it detected increased sharply. In other words, NORAD is picking up more incursions because it is looking for them, spurred on by the heightened awareness caused by the furor over the spy balloon, which floated over the continental United States for a week before an F-22 shot it down on Feb. 4.

“We have been more closely scrutinizing our airspace at these altitudes, including enhancing our radar, which may at least partly explain the increase in objects that we’ve detected over the past week,” Melissa Dalton, the assistant secretary of defense for homeland defense and hemispheric affairs, said at a news conference on Sunday evening.

American officials have not completely discounted theories that there could also be more objects, period. Some officials theorize that the objects could be from China, or another foreign power, and may be aimed at testing detection abilities after the spy balloon.

The object spotted approaching Lake Huron on Sunday was flying at 20,000 feet and presented a potential threat to civil aviation, so President Biden ordered it shot down, U.S. officials said. It had an octagonal structure with strings hanging off but had no discernible payload, they added.

U.S. and Canadian officials say the objects shot down on Friday and Saturday were also flying lower than the spy balloon, posing a greater danger to civilian aircraft, which prompted leaders to order them destroyed. Those two objects were flying over parts of Alaska and the Yukon that have few residents, and the third object downed on Sunday was over water, so risks posed by falling debris were minimal, they said.

The spy balloon that drifted across the United States flew much higher, at 60,000 feet, and did not pose a danger to aircraft. But any falling debris could have hit people on the ground, Pentagon officials said.

Throughout the weekend, officials said they were still trying to determine what the three objects were. The first, a Defense Department official said, is most likely not a balloon — and it broke into pieces after it was shot down on Friday. Saturday’s object was described by Canadian authorities as cylindrical, and American officials say it is more likely it was a balloon of some kind. Sunday’s object appeared unlikely to be a balloon, one official said.

NORAD radar tracked the first two objects for at least 12 hours before they were shot down. But Defense Department officials have never said whether they picked the objects up on radar before they neared American airspace. One official said it is unclear what keeps the objects aloft.

U.S. officials said they are reviewing video and other sensor readings collected by the American pilots who observed the objects before their destruction. But the exact nature of the objects, where they are from and what they were intended for will not be confirmed until the F.B.I. and the Royal Canadian Mounted Police have the chance to thoroughly examine the debris, officials said.

Asked during a news conference on Sunday whether he had ruled out extraterrestrial origins, Gen. Glen D. VanHerck, the commander of the Air Force’s Northern Command, said, “I haven’t ruled out anything at this point.” But in interviews Sunday, national security officials discounted any thoughts that what the Air Force shot out of the sky represented any sort of alien visitors. No one, one senior official said, thinks these things are anything other than devices fashioned here on Earth.

Luis Elizondo, the military intelligence officer who ran the Pentagon’s U.F.O. program until 2017, concurred. But he said that the Biden administration must find a way to balance vigilance over what is going on in the skies above America against “chasing our tail” whenever something unknown shows up — a tough task, he said.

For years, adversaries have sent low-tech gadgets into the skies above the United States, Mr. Elizondo said.

“What’s happening now is you have low-end technology being used to harass America,” he said in an interview. “It is a high-impact, low-cost way for China to do this, and the more you look up in the sky, the more you will see.”

At the urging of Congress, the Pentagon and intelligence agencies have intensified their study of unexplained incidents near military bases in accurate years. The studies on what the intelligence community calls unidentified aerial phenomena have pinpointed previously undetected efforts to conduct surveillance on American military exercises and bases. Many of those unexplained incidents have been balloons, and some of them are now believed to be attempted surveillance activity by China or other powers, both using balloons and surveillance drones.

In a public report released last month, the intelligence community said that of 366 unexplained incidents, 163 were later identified as balloons. A related classified document whose findings were reported this month by The New York Times said at least two incidents at U.S. military bases could be examples of advanced aerial technology, possibly developed by China.

“We can now assess flight patterns and trajectory in a much more scientific way,” said Senator Kirsten Gillibrand, a New York Democrat who wrote the accurate legislation mandating greater internal military reporting and analysis of aerial phenomena, leading to more documentation of sightings. “You need to know who’s using the technology and what it is.”

The most alarming theory under consideration by some U.S. officials is that the objects are sent by China or another power in an attempt to learn more about American radar or early warning systems.

A senior administration official said one theory — and the person stressed that it is just a theory — is that China or Russia sent the objects to test American intelligence-gathering capabilities. They could be sent to learn both how quickly the United States becomes aware of an intrusion and how quickly the military can respond to such an incursion, the official said.

American officials are united in their belief that the spy balloon that transited the United States was a Chinese machine meant to conduct surveillance on American military bases. Officials said it was unclear if China had complete control of the balloon during its whole journey. But officials said China did have at least a limited ability to steer it, and the balloon maneuvered on Feb. 3 before it was shot down the next day.

Another American official said the Chinese spy balloon was equipped with a self-destruct mechanism, but Beijing did not use it, a potential sign that Chinese officials wanted to continue to collect intelligence, even after it was discovered.

The disclosure of the balloon by the Pentagon on Feb. 2 led to a public diplomatic crisis between China and the United States. Beijing said it had the right to respond further. On Sunday, a Chinese newspaper reported that local maritime authorities in Shandong Province on the east coast had spotted an “unidentified flying object” in waters by the city of Rizhao and were preparing to shoot it down. State-run news organizations reposted the information.

If any of the devices destroyed in North America over the past three days were Chinese, it would amount to a major provocation on the heels of the spy balloon, one reason some officials said not to jump to the conclusion that the objects are surveillance devices sent from Beijing.

Officials in Beijing seem to want to limit tensions over the spy balloon, suggesting to some U.S. officials that the latest objects are less likely to be deliberate Chinese provocations or tests.

Pentagon officials have been raising flags about deficiencies in North America’s aging warning systems, radar and sensors.

Speaking last year at the Aspen Security Conference in Colorado, General VanHerck said that the United States had struggled to detect certain intrusions, what he called “domain awareness challenges.” General VanHerck said the NORAD radars could not adequately detect hypersonics and other threats.

But, he also said, the United States and Canada were investing in new over-the-horizon radar to better identify potential threats, as well as artificial intelligence systems to help pick out possible intrusions.

“I’m very encouraged with where we’re going,” General VanHerck said last July, “but we still have some challenges to work on.”

Killexams : Where to collect three objects to act as AI test vessels in Fortnite Chapter 4 Season 1

Fortnite’s second part of the Oathbound questline has kicked off with the introduction of Rift Warden Stellan, a mysterious figure who asks that players build a rift gate on the island. However, as other characters have become suspicious of the warden, you will need to do some investigating by first collecting specific objects for testing on the island. This guide will breakdown where you can locate all of the quest’s objects in the battle royale.

Unlike previous challenges in the questline, you will be required to find all of its test vessel objects in a single match, as dying will reset your progress completely. Luckily, there are only three items in total, and each are placed in the top-left corner of the map. These are spread out from west of The Citadel to even the snowy region, so it is highly recommended you bring one of the game’s vehicles in order to collect them all before the end of a match. You can find all of the object locations marked and detailed below.

  • Test vessel object location #1: This item is a shell that is located southwest of The Citadel and is sitting on a beach left of the Western Watch landmark’s bridge.
  • Test vessel object location #2: The next object is a taco which spawns near the food stands in the center of Anvil Square.
  • Test vessel object location #3: Lastly, you can head to Crankshot’s Cabin northeast of Anvil Square to discover the last object, a stuffed Cuddle Team Leader bear.

Additionally, players struggling to discover the items may want to pick up the Falcon Scout in order to fly over their areas and ping their location. If you are panic there may be enemies near them, the device can also scan and tag enemies for a short time. Once these objects are found, you will be granted an extra 20,000 XP, and Amie will then ask for you to visit one of her Hologram Braziers.
