Proof that $(n1)m!>(m1)!−1$ does not hold for $m>n$

The inequality does hold for $m=1,n=0$ so you need to exclude that case. Otherwise $m! gt 1$ and we can say $(m1)!-1=(m1)m!-1=(n1)m!(m-n)m!-1 gt (n1)m!$ because $m-n ge 1$

Prove $m^3 leq 2^m$ for $m geq 10$ with induction [duplicate]

Your second equivalence is wrong. It has to be: $$k^3 3k^2 3k 1 leq 2^k 2^k impliedby k^3 leq 2^k land 3k^2 3k 1 leq 2^k$$Now $k^3 leq 2^k$ by the induction hypothesis.For the last inequality, it is much easier to prove $3k^23k1leq k^3$, because $k^3 leq 2^k$ by the induction hypothesis.Now you just have to prove $-k^33k^23k1leq 0$ (for $k geq 10$) which can be done by simple function analysis.

Prove A^m is nonsingluar and (A^m)^-1=(A^-1)^m?

Do you know anything about A? I am assuming A is nonsingular or else your claim is false for m = 1. A matrix is nonsingular iff it is invertible. Alternatively, a matrix is nonsingular iff its determinant is nonzero. Since matrix A is nonzero, det(A) is not 0. So, det(A^m) = det(A)^m is nonzero. Therefore, A^m is invertible and hence nonsingular.

Holographic Cloud HCDP Online Display Platform Provides Low Data Rate Internet Access for Mobile Pho
With the development of information technology, the digital transformation of the exhibition hall has become a worldwide trend in the field of exhibition design. Digital pavilions such as "digital Forbidden City" and "digital Dunhuang" let us enjoy unprecedented shock. With the arrival of the film Avatar, 3D technology has really entered the public's life. Holographic technology is amazing in digital interpretation. The interpretation of holographic sand table and image presentation make the demonstration items "live" and "move".The digital exhibition hall integrates multimedia creativity, breaking the time and space constraints of the traditional exhibition hall. The display content presents a design mode of virtual and real combination, making the display more scientific and technological.The change of science and technology and the development of technology have triggered the transformation of the times. Digital display pays more attention to the audience, which greatly improves the subjective initiative of participants, that is, the ability to display information.Digital display industry takes digital image as the core and has always been considered to belong to CG (digital image) industry, but this is obviously not completely appropriate. Through the combination of three-dimensional digital image and touch screen, infrared sensor, projection and other hardware, digital display has completely gone beyond the scope of digital image. It emphasizes the functionality of display, experience and interaction. Compared with CG, it is closer to the display industry. It is a higher-level display industry generated by the combination of three-dimensional digital image technology and display applications. Compared with the traditional display mode of "product display board", digital display has incomparable advantages.The most important feature of digital display is to visualize information. Whether it is text information, an idea or even a feeling, it can be transformed into three-dimensional digital images.Vision is the fastest way for human beings to obtain information. An image contains countless information points, which can be obtained in an instant by looking at the picture. If expressed in words or language, it not only takes a lot of time, but also prone to omission and misunderstanding. Therefore, digital display is a high-speed channel to establish the communication between virtual information and the real world by using visual images. For example, the advantage of digital display has been widely used in the display of the real estate industry. Developers use virtual three-dimensional images to visually display the real estate, so that consumers can see and buy at ease.The multimedia digital exhibition hall represented by WIMI. Us, a domestic holographic giant, uses a variety of multimedia and digital technologies (holographic technology), combined with the latest film and television animation technology, attracts audiences with a variety of novel technologies, takes multimedia and digital technology as display technology, and combines unique digital creative publicity content, Attract visitors with various novel technologies and realize the exhibition form of human-computer interaction. These include digital sand table, interactive projection, digital cinema, 3D promotional films, etc., which make the overall atmosphere of the exhibition hall more scientific and technological and give the audience a shocking visual experience.The traditional exhibition hall is generally displayed in the form of "exhibition board product commentator", which has a long history. In a very limited space, exhibition boards and products occupy a lot of space, which affects the transmission of information in the exhibition hall, and the display form is single.Micro beauty holographic digital exhibition hall is also called multimedia digital exhibition hall. The holographic presentation technology of micro beauty holographic cloud can create a virtualized integrated space presentation for the theme exhibition hall and build a theme museum with clear theme and ultimate effect. Give consideration to interaction, presentation, art and education.Holographic cloud HCDP online display platform comprehensively transplants the authenticity interaction and social attributes of offline exhibitions to the online, so as to build a new ecology of online exhibitions. Combined with the platform IP operation capability of holographic cloud, IP will be themed for offline commercial holographic exhibition.The digital exhibition hall displayed by Weimei holography is different from other traditional exhibitions. Especially in intelligence, interactivity and informatization. The digital exhibition hall generally has a main control system to control the classification, aggregation, reorganization, switching, etc. of all projects. Most of the items in the digital exhibition hall are controlled by gesture, motion capture and other interactive means, so the digital exhibition hall focuses on the interaction with users. This improves the interest of the whole exhibition hall. Many projects are displayed by means of information interaction such as face recognition or photo generation, which not only improves the interaction, but also plays a role in collecting user information.The digital application of micro beauty holography has been extended to all walks of life in the digital exhibition hall. Its application fields include holographic shopping experience, holographic live broadcast, holographic press conference, various theme pavilions of holographic government, holographic online holographic Exhibition Application and holographic IP commercial exhibition. For example, the digital exhibition hall of Memorial Hall combines various multimedia interactive exhibition items and themes with high-tech acousto-optic display means to leave a more direct display impression on visitors; The digital exhibition hall of the science and Technology Museum will reproduce the past history, characters and articles, so that visitors can experience an interesting journey of science, technology and culture like going back in time. The digital exhibition hall of enterprise pavilion integrates the enterprise culture into digital multimedia exhibition items and digital content display, and creates an interactive enterprise pavilion digital exhibition hall with distinct enterprise personality, etc.Digital image content combined with various hardware can derive a variety of display forms. Digital sand table, the combination of digital image content and sand table model, not only allows the audience to see the three-dimensional model, but also comprehensively understand various information of the area through the image content. 360 degree circular screen display system, with the screen surrounding the audience and shocking three-dimensional image content, can create a profound immersive experience. The multimedia interactive system can realize friendly man-machine interaction and exchange and quickly obtain rich information through the simple operation of the touch screen. In addition, there are interactive ground screen, interactive desktop, holographic projection, virtual book flipping, augmented reality... All kinds of display methods full of sense of science and technology. With the continuous combination of three-dimensional image content and more hardware, the display form of digital display will have unlimited possibilities.In the traditional display mode, "exhibition board product commentator" is the main display mode. Exhibition boards and products occupy a lot of space, and the area of exhibition board basically determines the amount of information that can be displayed. In today's increasingly expensive geographical space, this display is definitely not "green". In the digital display mode, an LCD can display the information of countless display boards, and can also adopt the dynamic picture content and interactive mode, which not only saves a lot of space, but also makes the display more vivid.Digital display has greatly surpassed the traditional display mode in terms of content and effect, and has completely exceeded the scope of traditional display in the field of application. At present, it has been widely used in real estate display, digital city, historic site restoration, virtual tour, activity special effects, project preview, industrial simulation... The content of the display has broken through the limitations of time, space and form. In the future, its application field will only be limited by people's imagination.The advent of 5g era has greatly improved the efficiency of digital display. The main advantage of 5g network is that the data transmission rate is much higher than the previous cellular network, up to 10 Gbit / s, faster than the current wired internet and 100 times faster than the previous 4G LTE cellular network. Another advantage is lower network latency (faster response time), less than 1 ms, compared with 30-70 MS for 4G. Due to faster data transmission, 5g network will not only provide services for mobile phones, but also become a general home and office network provider. The previous cellular network provided low data rate Internet access suitable for mobile phones, but a mobile phone transmission tower can not economically provide sufficient bandwidth as a general Internet provider of home computers.5g high data transmission rate and low delay are considered to have new applications in the near future. One application is practical virtual reality and augmented reality. Another application is the fast machine to machine interaction in the Internet of things.

If the Abs Doesnt Work Does That Mean the Traction Control Doesnt Either ?
If the Abs Doesnt Work Does That Mean the Traction Control Doesnt Either ?
YEPPER! They both rely on working ABS SPEED sensors inthe WHEELS! ONE thing most people forget is to have the BRAEK FLDUI flushed and FILLED every 2-3years or when the fluid turns BROWN! DOMESTIC car makers never tell you this, but it is STILL a necessary part of AUTO care. Use ONLY the genuine AC DELCO fluids from a SEALED CONTAINER! WHY, you ask??? because all brake fluid is HYGROSCOPIC1. How can I decrease friction and add traction to my mousetrap car?Good Mouse Trap Car Designs2. are 2WD trucks really bad in inclimate weather, snow, rain etc?No problem.Go for it.You can always put weight in the bed to aid in traction if needed3. How effect auto and manual gear system to differential separately.?Manually controlled automatic transmissions Most automatic transmissions offer the driver a certain amount of manual control over the transmission's shifts (beyond the obvious selection of forward, reverse, or neutral). Those controls take several forms: Throttle kickdown Most automatic transmissions include some means of forcing a downshift into the lowest possible gear ratio if the throttle pedal is fully depressed. In many older designs, kickdown is accomplished by mechanically actuating a valve inside the transmission. Most modern designs use a solenoid-operated valve that is triggered by a switch on the throttle linkage or by the engine control unit (ECU) in response to an abrupt increase in engine power. Mode selection Allows the driver to choose between preset shifting programs. For example, Economy mode saves fuel by upshifting at lower engine speeds, while Sport mode (aka "Power" or "Performance") delays upshifting for maximum acceleration. Some transmission units also have Winter mode, where higher gear ratios are chosen to keep revs as low as possible while on slippery surfaces. The modes also change how the computer responds to throttle input. Low gear ranges Conventionally, automatic transmissions have selector positions that allow the driver to limit the maximum ratio that the transmission may engage. On older transmissions, this was accomplished by a mechanical lockout in the transmission valve body preventing an upshift until the lockout was disengaged; on computer-controlled transmissions, the same effect is accomplished by firmware. The transmission can still upshift and downshift automatically between the remaining ratios: for example, in the 3 range, a transmission could shift from first to second to third, but not into fourth or higher ratios. Some transmissions will still upshift automatically into the higher ratio if the engine reaches its maximum permissible speed in the selected range. Manual controls Some transmissions have a mode in which the driver has full control of ratio changes (either by moving the selector, or through the use of buttons or paddles), completely overriding the automated function of the hydraulic controller. Such control is particularly useful in cornering, to avoid unwanted upshifts or downshifts that could compromise the vehicle's balance or traction. "Manumatic" shifters, first popularized by Porsche in the 1990s under the trade name Tiptronic, have become a popular option on sports cars and other performance vehicles. With the near-universal prevalence of electronically controlled transmissions, they are comparatively simple and inexpensive, requiring only software changes, and the provision of the actual manual controls for the driver. The amount of true manual control provided is highly variable: some systems will override the driver's selections under certain conditions, generally in the interest of preventing engine damage. Since these gearboxes also have a throttle kickdown switch, it is impossible to fully exploit the engine power at low to medium engine speeds,4. Where do I put a traction pad on a 6' 5" twin fin Fish Surfboard?john f and johnny have very accurate answers5. Anti lock and traction control light comes on at 60 pmh?If all your tires are the same size and are all worn about the same amount, you probably have an intermittant wheel speed sensor problem. Get the system scanned there will be a code stored even if the light is out and it will tell you which sensor has the problem. I will bet on the right rear sensor. You can ohm test the sensors, they should all read the same amount.
MediaTek Helio X30 Specification Leakage, Transmission and Production TSMC 10 Nm
MediaTek Helio X30 Specification Leakage, Transmission and Production TSMC 10 Nm
MediaTek's "Helio X20" system single chip is the world's first deca core central processing unit (CPU), and then launched a slightly faster Helio X25, which will be built in "Meizu Pro 6" and "LETV le2" smartphones in the future. Now, according to the latest news, MediaTek plans to start building a "Helio x30" using TSMC's 10 nm process technology, and the latest specifications flow out.On the 30th, phone arena and gsmarena quoted China's MTK mobile network as saying that people familiar with the matter disclosed that x30 will further tap the potential of three clusters and ten cores. It is confirmed that it will not only apply the 10 nm process, but also adopt the TSMC 10 nm FinFET process. It is estimated that the "tape out" will be successful as soon as June, and it is expected to achieve mass production by the end of the year.Although Helio x30 is still the "three clusters and ten cores" design proposed by MediaTek, it has been greatly improved in terms of processor core and main frequency. X30 will be composed of ten cores, including two a7x 2.8GhZ, four A53 2.2GHz and four A35 2GHz. Among them, two a7x cores are not accurately named for the time being. It is the latest product of arm, code named "Artemis", It will not be officially released until the middle of the year at the earliest. Compared with A72, Artemis has at least 20% performance improvement and reduced power consumption.The A35 has excellent power-saving efficiency and 40% faster computing speed than the previous cortex-a7 core. In addition, Artemis is the next generation core produced by arm after cortex-a72, which should compete with Qualcomm's kryo solution. Using TSMC's 10 nm process means that the power saving efficiency will be 100% higher than that of Helio X20.Not only the process and the core / main frequency are greatly upgraded, the network part of Helio x30 is also significantly strengthened. The x30 will return to the embrace of img, integrate powervr 7-series MP4 GPU, support up to 26 million graphic lenses, dual cameras and VR technology. The network will support all Netcom and support cat.13 standard (previously transferred to cat.10).However, the above news is only a rumor, and we'd better have reservations about it.
Dear Chefs: Should I Use Extra Virgin Olive Oil with My Gourmet Pasta Or Regular Olive Oil?
Dear Chefs: Should I Use Extra Virgin Olive Oil with My Gourmet Pasta Or Regular Olive Oil?
dear chefs: should i use extra virgin olive oil with my gourmet pasta or regular olive oil?who doesnt love a virgin huh huh ??? wink wink lol lol— — — — — —Can you substitute extra virgin olive oil for vegetable oil in a recipe?yes, although the olive oil would taste alot better and it better for your health, but oil is oil and you can almost always replace the type with another— — — — — —Any tips on how to control eczema?When I was your age, I had eczema on my hands and feet - do not need to tell you how horrible it was - my hands were like raw meat for 5 long years. saw the doctors and was told the same as you - this will never go away, all you can do is control it. I started doing my own research. and what I found has completely 100% CURED my eczema - I have not had an outbreak in 20 years. it's gone. All skin problems like eczema come from having unhealthy skin. so, the skin is unhealthy, and that allows things like eczema, psoriasis etc. to get a foothold. The skin is not healthy enough to stop the problem. So, the number one thing to focus on is to have healthy skin. I was on cortisone type cream - did not help. I was told to moisturize 8 times a day, did not help. Finally, I found what would work. I hope this will help you. Our bodies make Gamma linolic acid (GLA) and this sort of 'seals' the skin surface. but if the body is not able to make enough GLA, then the skin is not protected, it is not healthy. there are 2 plants that make GLA - the borage plant, and the primrose - by taking borage oil or primrose oil - available at all the health food stores and some pharmacies - you GET the GLA without having to rely on your body making enough. It is a supplement, but really a food - it's just oil, so no side effects, no addictions etc. I have no idea why my body was not making enough, but as long as I take borage or primrose oil daily, I have literally been fine. It did take a few weeks though, to fully clear up for good. the oil is not cheap - the seeds from the plant are handpicked etc. Try taking vitamin E, as well, also known to be good for the skin. both these oils moisturize from the inside out. much better than slathering yourself with moisturizers. Definitely avoid anything you are allergic to - stay away from the caffeine, even if the oil works. Take extra Vitamin C - which is an immune booster, and helps reduce stress (stress often triggers skin conditions) Drink lots of plain water - stay hydrated Avoid harsh chemicals on the skin, INCLUDING soap, non-soap cleaners AND moisturizers. these all dry out (damage.) your skin at this point. stay away from them for now, at least. Moisturize with raw coconut oil - the polynesians have been using it for hundreds of years and have beautiful skin and hair. It is all natural, no additives, no chemicals. I have been using it for years, and it feels good on the skin. Apply very little, and if you put on too much, just blot it off. you could use other raw oils, such as extra virgin olive oil, but I have found that to be too heavy, clogs pours. there are probably others (shea butter?) I do not know, because I only use the coconut oil. For washing. skin has an acid mantle - everytime you use soap, you strip off the acid which again, makes your skin vulnerable. apple cider vinegar restores the acid mantle to skin and hair. so in a bathtub of water, you would add 2 cups of apple cider vinegar. to a sinkful of water, just to wash your face etc. add just 1/4 cup of apple cider vinegar - if you can find the raw apple cider vinegar, that is BEST - it is loaded with vitamins and minerals. and is a natural deodorizer. do not worry about the vinegar smell, it goes away when it dries. you wo not smell like french fries. :-) Do not use any other type of vinegar - again, apple cider vinegar is natural. If you use soap, be sure to rinse in the vinegar water. to restore the acid mantle. for example, you could take a shower, use soap (very little), and then fill a jug with warm water and splash of vinegar, and dump that over yourself. air dry if possible. or wait a bit and then pat dry. I hope this will help, but whatever you do, keep looking for ways to improve your skin health, and the eczema will go away.

Due to the updated development tools, it is necessary to repeat the previous content in this blog. Today, we first demonstrate how to use vivado to develop pure logic engineering, that is, only on pl. Just recently, I was watching Lei silei's "startling the core step by step - internal design analysis of soft core processor", so I moved some experiments to zed board for verification. Children's shoes interested in openrisc can follow rill's column to further obtain learning resources.First, it briefly introduces the openrisc software development, and refers to the steps of establishing the development environment in Lei silei's book.1. Download the GNU development environment. You can directly download the configured VirtualBox image. The link is ftp://openrisc.opencores.org/virtualbox-image/ , the FTP user name and password are openrisc. Download version 2011-12-15.2. Download and install VirtualBox. Create a new virtual machine, configure it as Linux, Ubuntu, 512MB memory (not high demand), and use the existing virtual hard disk (openrisc_ubuntu_2011-12-15. VDI)Once the installation is complete, it can be started. The GNU tool chain is or32 elf -... (it can be ar, as, G , GCC, etc.). Root password: openriscSet the shared folders of windows and virtual machines in VirtualBox. Close the Ubuntu system, select "Settings" in the VirtualBox main interface, and add the windows shared folder e: share in the "data space", which is named share in Ubuntu. After setting, start the Ubuntu system, and enter the command sudo mount - t vboxsf share / MNT / sharefolder in the terminalThe virtual machine is running as shown in the figure (if the figure is too large to see completely, you can right-click to save it as a picture and view it locally).3.

Tritium Launches the World's First Scalable Electric Vehicle Charging Platform
On November 17 local time, tritium launched MSc hardware platform, the first platform that can realize truly scalable electric vehicle charging network anywhere in the world. Tritium is a global leader in direct current (DC) fast charging technology for electric vehicles.The modular scalable charging (MSc) hardware platform allows customers to flexibly increase the power level of the charger with the improvement of the charging capacity of electric vehicles, and set different rates with this improvement. The charging pile power of tritium can be increased from 25kW to 350kW and above.While launching the platform, tritium also released the first charging pile based on the platform - the new generation rtm75 DC fast charging pile, which allows drivers to increase the range of the car by 75 km (46 miles) in 10 minutes.MSc hardware platform enables the electric vehicle charging website to have real timeless capabilityPreviously, EV charging network operators were required to install pre-determined power chargers, such as 50KW, 175kW or 350kW.However, the MSc hardware platform can quickly install 25kW additional rectifiers in each charging pile supported by the MSC, such as rtm75 and tritium future iterative rectifiers. The charging pile operator can purchase charging piles with an initial power of 25kW or 50KW according to the current power demand. However, with the increase of charging demand, the power can be expanded to 75kW.The rtm75 charging pile can be used for charging applications in workplaces, public places and fleet warehousesIn order to meet the needs of public charging infrastructure, tritium has worked with customers to develop a scalable solution for retail, urban and public environments. In such environments, the ease of use of the charging infrastructure is most important.Rtm75 can charge two electric vehicles at the same time, and can support all charging standards in the market such as CCS and chademo to meet the needs of batteries with voltages up to 920v.In addition, rtm75 is also equipped with plug and charge technology, which does not require credit card payment or RFID authentication on the charging pile. The driver can use the charging cable to pay when communicating directly with the vehicle; The driver only needs to plug in the electric vehicle plug to charge the vehicle. Then you can drive away after knowing that the payment has been completed automatically and security management has been obtained.
The Essential Difference Between Artificial Intelligence and Automation
The Essential Difference Between Artificial Intelligence and Automation
The Research Report on the development of "artificial intelligence manufacturing" industry jointly studied and prepared by the Institute of industrial economics of the Chinese Academy of Social Sciences and Tencent Research Institute believes that the "intelligent" process put into "artificial intelligence" is essentially different from the past process of manufacturing pursuing "automation".Li Xiaohua, chief editor of the report, director of the Research Office of the Institute of industrial economics of the Chinese Academy of Social Sciences and researcher, said that automation pursues automatic machine production, and its essence is "machine replacing people", emphasizing large-scale machine production. Intelligent pursues the flexible production of machines, which is essentially "man-machine cooperation", emphasizing that machines can independently cooperate with the changes of factors and people's work. Therefore, what "artificial intelligence manufacturing" will pursue in the future should not be a simple "machine replacing people", but should pull the extremely refined and even alienated workers' assembly line work since the industrial revolution back to the "people-oriented" organization mode, that is, let machines undertake more simple, repetitive and even dangerous work, while people undertake more management and creative work. Li Xiaohua said that "artificial intelligence manufacturing" is bound to move towards the platform mode. The popularity and development of the Internet gave birth to the "platform model". The speed of information dissemination in the platform has been greatly increased and the transaction cost has been greatly reduced, which has effectively promoted the improvement of economic efficiency. In recent years, this model of the Internet has gradually expanded to all walks of life. For the manufacturing industry, this model is the "industrial Internet platform".The important foundation for the realization of "artificial intelligence manufacturing" in the future is the industrial Internet platform, which provides the industry with general computing power (Industrial cloud computing and edge computing), computing data (industrial big data) and algorithm (industrial artificial intelligence), so as to promote the transformation and upgrading of the whole industry. According to the data of the research company, the proportion of the global industrial Internet platform market represented by these three parts in the overall "artificial intelligence manufacturing" will increase from 24% in 2016 to 36% in 2025, reaching US $260 billion.After decades of development, the Internet has become the backbone of the information revolution and the leader of the current development of artificial intelligence technology. Its experience and accumulation in connection, data, cloud, algorithm and security can effectively support it to promote the integration of artificial intelligence and various industries.Li Xiaohua believes that for "artificial intelligence manufacturing", there are three typical scenarios assisted by the Internet. Product intelligence, intelligent upgrade from software to hardware. The Internet can embed its artificial intelligence algorithms into products in a capacity encapsulation and open way, so as to help the manufacturing industry produce a new generation of intelligent products. For example, Google has developed an intelligent chip TPU dedicated to large-scale machine learning, Tencent's AI open platform provides AI capabilities such as computer vision, and Amazon has launched intelligent voice echo embedded with artificial intelligence voice assistant.Service intelligence, improve the accuracy of marketing and after-sales. The Internet can make use of its artificial intelligence algorithm to provide more accurate value-added services to manufacturing enterprises. First, pre-sales marketing uses artificial intelligence to conduct multidimensional analysis of user side demand data to achieve more real-time and accurate advertising information transmission. The second is after-sales maintenance, which realizes the real-time monitoring, management and risk early warning of manufacturing products with the Internet of things, big data and artificial intelligence algorithms. For example, Sany Heavy Industry, in combination with Tencent cloud, connected 300000 devices distributed around the world to the platform, collected nearly 10000 operation parameters in real time, remotely managed the operation status of a large equipment group by using big data and intelligent algorithms, effectively realized fault risk early warning, greatly improved the troubleshooting efficiency and reduced the maintenance cost. Production intelligence and enhance the independent production capacity of machines. The Internet can help manufacturing enterprises embed artificial intelligence technology into the production process, so that machines can realize independent production in more complex situations, so as to comprehensively improve production efficiency. At present, it is mainly used in process optimization, intelligent quality inspection and other fields.The report systematically studies the integrated development of artificial intelligence and manufacturing industry from the aspects of concept, current situation, impact and countermeasures, focuses on the resources and capabilities of the Internet, and points out the direction for giving better play to the role of the Internet.
