![]() Starting in April, 2023, to provide PDF developers and stakeholders with their accustomed level of access, the PDF Association and its sponsors made ISO 32000-2 available for download at no cost. ISO's publication of ISO 32000-2 in 2017 ended the 24-year tradition of the latest PDF specification being freely available from Adobe. ISO 32000-2 does not include any proprietary technologies as normative references. In December 2020, the second edition of PDF 2.0, ISO 32000-2:2020, was published, including clarifications, corrections, and critical updates to normative references. Many of them are also not supported by popular third-party implementations of PDF. These proprietary technologies are not standardized and their specification is published only on Adobe's website. PDF 1.7, the sixth edition of the PDF specification that became ISO 32000-1, includes some proprietary technologies defined only by Adobe, such as Adobe XML Forms Architecture (XFA) and JavaScript extension for Acrobat, which are referenced by ISO 32000-1 as normative and indispensable for the full implementation of the ISO 32000-1 specification. In 2008, Adobe published a Public Patent License to ISO 32000-1 granting royalty-free rights for all patents owned by Adobe that are necessary to make, use, sell, and distribute PDF-compliant implementations. PDF was a proprietary format controlled by Adobe until it was released as an open standard on July 1, 2008, and published by the International Organization for Standardization as ISO 32000-1:2008, at which time control of the specification passed to an ISO Committee of volunteer industry experts. In the early years PDF was popular mainly in desktop publishing workflows, and competed with a variety of formats such as DjVu, Envoy, Common Ground Digital Paper, Farallon Replica and even Adobe's own PostScript format. ![]() The PDF specification also provides for encryption and digital signatures, file attachments, and metadata to enable workflows requiring these features.Īdobe Systems made the PDF specification available free of charge in 1993. PDF files may contain a variety of content besides flat text and graphics including logical structuring elements, interactive elements such as annotations and form-fields, layers, rich media (including video content), three-dimensional objects using U3D or PRC, and various other data formats. The last edition as ISO 32000-2:2020 was published in December 2020. PDF was standardized as ISO 32000 in 2008. PDF has its roots in "The Camelot Project" initiated by Adobe co-founder John Warnock in 1991. Based on the PostScript language, each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, vector graphics, raster images and other information needed to display it. Extend Reader functionality using the free Acrobat SDK.Ĭlick to download Adobe Acrobat XI.Portable Document Format ( PDF), standardized as ISO 32000, is a file format developed by Adobe in 1992 to present documents, including text formatting and images, in a manner independent of application software, hardware, and operating systems.

Retrograde motion planets8/4/2023 ![]() ![]() The asteroid 514107 Kaʻepaokaʻawela has a retrograde orbit. Consequently, although both moons are traveling in an eastward (prograde) direction, they appear to be traveling in opposite directions when viewed from the surface of Mars due to their orbital periods in relation to the rotational period of the planet.Īpparent path of Mars in 2009–2010 relative to the constellation Cancer, showing its “opposition loop” or “retrograde loop” Both moons orbit Mars in an eastward (prograde) direction however, Deimos has an orbital period of 1.23 Martian sidereal days, making it supersynchronous, whereas Phobos has an orbital period of 0.31 Martian sidereal days, making it subsynchronous. This phenomenon also occurs on Mars, which has two natural satellites, Phobos and Deimos. As a result, it looks like the Moon is travelling in the opposite direction, otherwise known as apparent retrograde motion. ![]() This means that the Earth completes one sidereal rotation before the Moon is able to complete one orbit. The apparent westward motion of the Moon from the Earth’s surface is actually an artifact of it being in a supersynchronous orbit. In actual fact, the Moon orbits the Earth from west to east, as do the vast majority of manmade satellites such as the International Space Station. ![]() Day after day however, the Moon appears to move to the east with respect to the stars. When standing on the Earth looking up at the sky, it would appear that the Moon travels from east to west, just as the Sun and the stars do. The earliest recorded use of prograde was in the early 18th century, although the term is now less common. While the terms direct and prograde are equivalent in this context, the former is the traditional term in astronomy. Direct motion or prograde motion is motion in the same direction as other bodies. Apparent retrograde motion is the apparent motion of a planet in a direction opposite to that of other bodies within its system, as observed from a particular vantage point. ![]()

Lantern lamps design8/4/2023 ![]() ![]() Many of these fixtures are available with designs and bulbs that mimic candles and oil lamps. Our Colonial period lighting fixtures and Williamsburg lights give you the best of both worlds: the ageless grace and charm of Colonial design with the modern convenience, efficiency and illumination of modern lantern lighting fixtures. ![]() Of course, despite Benjamin Franklin's adventures with kite flying, Americans still hadn't learned how to harness the power of electricity during the 18th century. We offer an outstanding selection of Williamsburg lighting fixtures and Colonial lighting fixtures. But if you can't get there or just want to adopt some intriguing Colonial designs in your own home or business, Destination Lighting is here to help. Williamsburg is well worth a visit for any history buff. The reenactors and restored buildings there give visitors a chance to imagine what life was like in America before it became the United States. Whether you are renovating an historical home or creating a colonial living space, these lanterns are a timeless design that can be hung in-door or out and come in a number of sizes and finish options.Set in the lush expanse of Tidewater Virginia, Colonial Williamsburg is a town of living history that re-creates American life and lifestyles before 1776. The center shaft was filled with whale oil then they would light the candle wicks. Tankard Chandelier / Model C1195N starting at $460 and Model C1196N starting at $335ĭating back to the 19th Century whalers used the tankard lamps to carve scrimshaw by. The simplistic design was popular during the early American period with yankee merchants and colonial tinsmiths. These triangle top lanterns are a reproduction of the traditional colonial lanterns in the early 1800's. York Lantern / Model O1121N / Price starting at $221 This lantern can be made in a very large scale size to accent any barn and turn it into a unique living space. Employing candles or oil fonts, and aided in light by a mercury glass reflector, the 19th century farmers could carry this lantern with them to tend to their livestock. With a handle for portability the barn lanterns were also placed by the front doors of residences. This Barn Lantern was originally used in shops, the livery barns and buildings of commerce. Livery Barn Lantern / Model O1126N / Price starting at $382 Today, this lantern remains a classic early lantern and is a worthy choice for practically any house or building. The double-roofed chimney was an efficient ventilator that kept drafts and wind from extinguishing the candles. New England roll-top lantern was adapted in the early 18th and 19th centuries. New England Adams/ Model: O1120N / Price: starting at $221, Lynn Lantern / Model O1128N / Price starting at $317 AND New England Ship’s Lantern / Model O1024G/ Price starting at $482 The lanterns are a popular choice for interior and exterior applications. The soldered wire guard protected the hand-blown glass from the frequent "NorEaster's" that batter the New England coasts. These Onion Lanterns originated in the New England Cape Cod area. Onion Lights / Model: H1177N, price: starting at $397 The beauty of their design still attracts buyers today. Many of our handcrafted lanterns at the Copper Lantern are historically accurate renditions of colonial lanterns that have been used for practical, everyday life well before the invention of electricity. ![]()

Sd card recovery for free8/4/2023 ![]() Each block is checked against a signature database which comes with the program and has grown in the type of files it can recover ever since PhotoRec's first version came out.įor example, PhotoRec identifies a JPEG file when a block begins with: Once this block size is known, PhotoRec reads the media block by block (or cluster by cluster). Otherwise, PhotoRec reads the media, sector by sector, searching for the first ten files, from which it calculates the block/cluster size from their locations. If the file system is not corrupted, this value can be read from the superblock (ext2/ext3/ext4) or volume boot record (FAT, NTFS). To recover these lost files, PhotoRec first tries to find the data block (or cluster) size. This means the data is still present on the file system, but only until some or all of it is overwritten by new file data. When a file is deleted, the meta-information about this file (file name, date/time, size, location of the first data block/cluster, etc.) is lost for example, in an ext3/ext4 file system, the names of deleted files are still present, but the location of the first data block is removed. ![]() The seek time of mechanical drives is significant for writing and reading data to/from a hard disk, so that's why it's important to keep the fragmentation to a minimum level. In general, most operating systems try to store the data in a contiguous way so as to minimize data fragmentation. The cluster or block size remains at a constant number of sectors after being initialized during the formatting of the file system. Want to know if PhotoRec can recover your files ? Upload a sample file via the PhotoRec online checker (BETA).įAT, NTFS, ext2/ext3/ext4 file systems store files in data blocks (also called clusters under Windows). The whole list of file formats recovered by PhotoRec contains more than 480 file extensions (about 300 file families). PhotoRec recognizes and recovers numerous file formats including ZIP, Office, PDF, HTML, JPEG and various graphics file formats. If there is no data fragmentation, which is often the case, it can recover the whole file. PhotoRec searches for known file headers. Olympus C350N, C860L, Mju 400 Digital, Stylus 300.PhotoRec has been successfully tested with various portable media players including iPod and the following Digital Cameras: PhotoRec works with hard disks, CD-ROMs, memory cards (CompactFlash, Memory Stick, Secure Digital/SD, SmartMedia, Microdrive, MMC, etc.), USB memory drives, DD raw image, EnCase E01 image, etc. Unfortunately, PhotoRec isn't able to deal with this - that's why it doesn't work well with ReiserFS. In order to increase performance, ReiserFS is able to store files inside the b*tree leaf nodes themselves, rather than storing the data somewhere else on the disk and pointing to it. ReiserFS includes some special optimizations centered around tails, a name for files and end portions of files that are smaller than a filesystem block. ![]() PhotoRec ignores the file system this way it works even if the file system is severely damaged. ![]() Windows 11/10/8.1/8/7/Vista/XP, Windows Server 2022/2019/2016/2012/2008/2003Īnd can be compiled on almost every Unix system.ĭownload TestDisk & PhotoRec File systems.This means that while using PhotoRec, you must not choose to write the recovered files to the same partition they were stored on. Important: As soon as a picture or file is accidentally deleted, or you discover any missing, do NOT save any more pictures or files to that memory device or hard disk drive otherwise you may overwrite your lost data. PhotoRec is a companion program to TestDisk, an application for recovering lost partitions on a wide variety of file systems and making non-bootable disks bootable again.įor more safety, PhotoRec uses read-only access to handle the drive or memory card you are about to recover lost data from. PhotoRec is free - this open source multi-platform application is distributed under GNU General Public License (GPLV v2+). PhotoRec ignores the file system and goes after the underlying data, so it will still work even if your media's file system has been severely damaged or reformatted. PhotoRec is file data recovery software designed to recover lost files including video, documents and archives from hard disks (Mechanical Hard drives, Solid State Drives.), CD-ROMs, and lost pictures (thus the Photo Recovery name) from digital camera memory.

Free human like text to speech8/4/2023 ![]() ![]() The ultra-high-definition column offers the same voice from A Bite of China, a documentary about Chinese cuisine. These customized voices include Ai Xia for customer service, Ai Yuan for literature, and Xiao Xian for live broadcast scenarios. However, the DAMO Academy Speech Laboratory provides about 100 kinds of customized voices on Alibaba Cloud made by speech synthesis with various scenes, voices, and accents but without restrictions. The voice of Dong Dong is an exclusive copyright held by the customization side. ![]() After the tuned TTS model is obtained, the voice of Dong Dong relies on Alibaba Cloud and can be used for all-weather voice broadcasting during the Winter Olympics.Īny refined voice that users want (like the customization process of Dong Dong) can be customized through these four steps. In the comprehensive evaluation of naturalness, Dong Dong is 98% close to the original target speaker. Finally, combining the three models, Dong Dong can switch her styles between a formal host and a talk show host. In addition, the emotional TTS enriches the speaker's emotion and speaking style. Moreover, the HIFI-TTS model can make the sound quality of the synthesized audio sound better. The DAMO Academy Speech Laboratory wanted to achieve the customized effect with human-like expression and developed the KAN-TTS model to make the rhythm more natural. Step 4: Model Training, Tuning, and Deployment The filtered audio can be labeled automatically by Automatic Speech Recognition (ASR), but it also needs manual inspection and adjustment. The amount of filtered audio can ensure phoneme coverage. Unlike traditionally manual quality inspection, The DAMO Academy Speech Laboratory performs automated style consistency screening based on audio features to ensure high consistency of the recorded audio. The audio quality determines the upper limit of the customized voice. ![]() In addition, data quality inspection is required after the recording. Recording instructions are required during the recording process. ![]() The audio recorded by the speaker with different states may vary significantly. Then, according to the hosting material of the Winter Olympics and the content of general scenarios, the text that the speaker of Dong Dong needs to record is designed through the calculation of phoneme coverage. The DAMO Academy Speech Laboratory invited the target speaker that meets the recording requirements of Dong Dong to the studio to ensure that the audio effect is stable and high quality. Then, a comprehensive evaluation is conducted based on the original audio and the preliminary synthesis effect to determine the target speaker. The audio of other specific texts is synthesized according to the one or two auditions mentioned previously. It uses personalized text-to-speech (PTTS) to evaluate the synthesis effect. The DAMO Academy Speech Laboratory is different from the traditionally direct selection of speakers. “The voice sounds like an 18 or 19-year-old girl, who speaks standard Mandarin with a sweet tone and is sporty, fashionable, and lively, such as Zhang Zifeng, a Chinese actress.” Then, multiple speakers are selected to audition one or two specific sentences. The DAMO Academy Speech Laboratory calls it a voice portrait. Step 1: Speaker Selectionįirst of all, it is necessary to be clear about what kind of voice you need. How can you customize a voice with human-like expressions? Let's start with Dong Dong, the virtual host during the 2022 Beijing Winter Olympics. Coupled with those emerging requirements, TTS is required to turn text into corresponding speech and make synthesized speech more expressive, with rhythm, sound quality, and emotion closer to a real person's voice. Nowadays, self-media publishers require video dubbing, and virtual characters are needed to combine with 2D images (and even 3D modeling) to communicate with people. What is speech synthesis? As the name implies, it means to transform the text into text-to-speech (TTS). Released by Alibaba Cloud Research Center ![]()

Gender fluid meaning in hindi8/4/2023 ![]() A “ friend” of mine once jokingly said, “No offence but don’t you think menstruation is your body’s way of discarding your identity.” Yes, it is. My uterus instead of being divine is often a burden to my identity. Undoubtedly, the female biology is marvelous but to me it’s often distressing. By equating our experiences, one is not only invalidating my dysphoria but also hijacking the queer space I belong in. This discomfort that I feel is not similar to something a cis woman experiences. Menstruation for cis women is not a constant reminder that they don’t belong in their bodies. When cis-het women compare queer experiences with that of their own, it isn’t always helpful. But whenever I have expressed my distress in front of cis-het women, their response is either “I too hate periods,” or “You should be proud of it. ![]() This means that certain aspects of my body that come as a consequence of the sex I am assigned at birth, often distress me – the most disturbing of them being menstruation. My gender identity also brings with itself the cargo of gender dysphoria. I sometimes feel like a woman, most times like a man and often neither. ![]() I am a human who falls under the non-binary spectrum which means my sex organ doesn’t define my gender identity. Then there are some who call me “ a chameleon”, “ a shape-shifter.” Even though the idea is quite tempting and I would love to let go of this mundane muggle life, I am most definitely a human and not a character from Harry Potter. Wearing a blazer or a skirt or putting on makeup is a part of gender expression and not gender identity Gender fluidity is a gender identity which means it is not related to just the physicality of a person. While gender identity is the personal conception of one’s self as male or female or both or neither. Gender expression is a way in which a person expresses their gender identity through appearance and behavior. I am genderfluid which means even though I have a vagina I do not identify as a woman. Even though gender is a social construct, gender identity most definitely isn’t. A person born with a female sex may identify as a man or a woman or neither or both. But gender identity is not necessarily related to the genitals we are born with. When I came out as genderfluid, a very considerate cis-het ally said, “Isn’t gender a social construct? So if male and female doesn’t exist, aren’t we all fluid?” Gender is most definitely a social construct which conditions us to abide by the gender roles assigned to our sexes, since childhood. The oh-so-supportive cis-het friends who claim to be proud allies of the community, but more often than not, really hurt our feelings with snippets of micro-aggression behind closed doors. But I have come across another kind who alienates me the most. We all are familiar with these two types of cis-het people in our lives. Or, if they are feeling particularly queerphobic that day, then the conversation becomes a series of accusations and objections about my entire existence. One, where I relentlessly try to make my fellow human understand why I am not a woman while they insist on proving me wrong by pointing at either my breasts or reminding me of the nature of my genitals. What follows this brilliant observation then leads to two types of conversations. Many dismiss it altogether, while some very politely remind me, “But you are a woman!” The confusion on their faces makes my sexuality seem like a quantum physics formula. the Extra-Terrestrial, and they are Elliot, from the Steven Spielberg film. When I say I am a genderfluid pansexual person, cis-het people look at me like I have uttered something blasphemous. People who are nonbinary don’t identify exclusively as female or male.Trigger Warning: Gender Dysphoria, Queerphobia The flag was created as an addition, not a replacement. The Nonbinary Flag was created in 2014 after members of the nonbinary community felt the Genderqueer Flag didn’t represent them. Learn them all: Here's what each Pride Flag means What do the colors of the Nonbinary Flag mean? Gender identity, expression and more: LGBTQ definitions every ally should know “They are all interrelated as well as key components in their own right.” “The three colors are not meant to indicate that any of these identities are entirely separate or opposites of one another conceptually,” Roxie wrote on their website.

Parallax definition space8/4/2023 ![]() ![]() Importance of parallax: Danish astronomer Tycho Brahe reasoned that the distance of the object may be determined by measuring the amount of parallax. Parallax on rifle scopes is often set at 100 or 150 yardsįor further reading on parallax, click on this link to one of my blog articles.Presentation on theme: "Determining the Distances to Astronomical Objects"- Presentation transcript:ġ Determining the Distances to Astronomical ObjectsĢ Parallax Parallax view: the variation in angle that occurs when viewing a nearby object from different places.Parallax on shotgun scopes is often set at 60 or 75 yards.Parallax on rimfire scopes is often set at 50 yards. ![]() Airgun scopes are generally listed as such and are durable enough to withstand the severe punishment a reverse-recoil spring piston air rifle delivers. The slightly different points of impact possible in hunting applications make the usefulness of this feature negligible.Īirgun scopes and higher power scopes almost always have adjustable objectives that go down to 10 meters (33 feet), which is a standard airgun competition distance. It's just an unnecessary feature to get in your way, and another thing to think about. Remember, adjustable objectives are generally not needed for hunting scopes under 10 or even a bit more power. If a person only looked directly through the center of their scopes the same every time, parallax would not be an issue, but only a robot could be that repeatable, not a human. ![]() These scopes would be practically unusable at that distance. The answer was yes, a clear picture, but nodding my head even slightly caused the crosshairs to move inches off my target. I went into our warehouse and checked out several different brands. Just because you get a clear sight picture doesn't mean you are parallax free.Ī customer asked me the other day if he could get a clear picture through a 2x handgun scope at the 12-foot distance he shoots his air pistol from in his house. You also have another thing to think about if you have to adjust something, using precious time and perhaps a missed or at least hurried shot. A bad parallax setting may not only appear out of focus, but will wreak havoc on your group sizes, even though your shooting might be technically perfect.įor hunting big game, a parallax error will not be as significant as the movement your heartbeat and breathing will cause. Why is Parallax Important?Īirgun scopes sometimes have a high power of 18 or more, even for 10 meter targets. This will become even more common as time goes on. Recently, it has become popular to install parallax adjustment dials on the left side of the turret housing, which is much more convenient and user friendly. Parallax adjustments are made at the objective lens with a rotating dial marked in incremental distances. Looking down into the glass, watch the dot move in directions other than where it should be.Įxternal parallax adjustments, called adjustable objectives or side focuses, are generally on scopes of more than 10 power or on scopes that are used at close distances.Hold the glass an inch over the mark and move it around slightly in different directions.Put an inch or so of water in a clear drinking glass.Put a small mark from a pencil on a table.Here's a simpler example of how parallax works: This will also happen if the target is set at a much further distance, say 300 yards. The scope's "eye" is not focused at the proper distance. ![]() If you take one of these scopes that are set at 100 yards and put it in a vise on high power with the crosshairs centered on the bullseye of a target about 25 yards out and move your head slightly off-center to the left and right or up or down, you'll see the crosshairs move off the bullseye, even though the scope has not moved. Most rifle scopes in a medium-high variable power range, say 10X or slightly higher, which often don't have external parallax adjustments, are parallax corrected at either 100 or 150 yards. One way to help explain it is to picture the following: Parallax is hard for most people to understand. You need to adjust for parallax to ensure your reticle will be accurate at any viewing angle. If you notice your reticle is moving off target while changing your viewing angle, that's parallax. A simple definition of Parallax: a noticeable shift in reticle placement while looking through your scope at different angles ![]() |
