Rising Venture Capital Investments Coupled with Increasing R&D Activities in Autonomous Vehicles market to Drive Artificial Intelligence market in US Through 2021 According to TechSci Research report, "United States Artificial Intelligence market, By Application, By Region, By End User Competition Forecast & Opportunities, 2011-2021", the Artificial Intelligence market in the US is projected to grow at a CAGR of 75% during 2016 - 2021 on account of growing Artificial Intelligence technology adoption in consumer electronic devices, research and developmental activities in healthcare industry, unmanned aerial vehicles, autonomous cars, etc.

This research evaluates enterprise Robotics in the United States including companies, technologies, and solutions across industry verticals and applications. The report includes forecasts by industry vertical/application for 2017 through 2021. Leading industry verticals are beginning to see improved operational efficiency through the introduction of Robotics and Artificial Intelligence (AI). Robotics investment in many industries represents a substantial capital expenditure with the potential to dramatically reduce operational expenses through resource optimization, quality improvement, and waste reduction. Robotics in business will accelerate as less expensive hardware and improvements in AI lead to improved cost structures and increased integration with enterprise software systems respectively. The massive amount of data generated by Robotics will create opportunities for data analytics and AI-enabled decision support systems. Emerging areas for enterprise Robotics include Robotics as a Service, Cloud Robotics, and General-Purpose Robotics. Artificial Intelligence is the machines which are designed and programmed in such a manner that they and think and act like a human. Artificial Intelligence becomes the important part of our dAIly life. Our life is changed by AI because this technology is used in a wide area of day to day services. These technologies reduce human effort. Now in many industries, people are using this technology to develop machine slaves to perform the different activity. Using the machine for the work speed up your process of doing work and give you an accurate result. It is very likely that areas in which the universal intelligence of the human level is not needed will reach maturity and produce reliable high-quality products in the next decade. Efforts to improve quality and expand boundaries for text and video understanding systems, and to give home robots greater reliability and overall utility, will lead to systems of common sense linking learning and action together in all these modalities. Especially given the massive growth of machine-readable data on human activities and the need for machines that understand human values if such machines are reliable and useful. Public and private sources of knowledge will become part of society. If earlier AI developers were trying to create a machine that could perform tasks independently, at the moment the situation has changed and the goal that is put before Artificial Intelligence is to help a person in various matters. Thanks to the modern approach, Artificial Intelligence starts to simplify and improve various
processes; another promising scope is the prediction and even some manipulation of human behaviour in advertising systems. You can expect an increase in the quality of the work of search engines and machine translation. This will be possible due to the fact that the computer will begin to understand and analyse the meaning of the text.

Why to change the leadership of ailing organizations

Abdul Aziz Khan

It has been a general practice for mature organizations to continually change the main leadership to maintain a growth trend. This leadership change at the highest level is not recommended in all situations. In contrast to it, a lot of organizations have delivered astonishing results without changing the CEO for a very longer period.
So, which of the policy is workable, and in what situations? Let us delve into it.

The most important tool humanity has conceived

Kelvin Ogba Dafiaghor

Artificial Intelligence is the development of computer systems to be able to perform task normally requiring human intelligence. Examples are visual perception, speech recognition, decision-making and translation between languages e.t.c. Artificial intelligence is an area of computer science that emphasizes the creation of intelligent machines that work and react like humans. Artificial intelligence is the technology that drives most modern technology from self driving cars to even our snap chart filter. Artificial intelligence as the best tool to solve global poverty. Artificial intelligence can be used to bridge the gap between the have and the have not between the develop and the underdeveloped world. The purpose of this study is to present a systematic view why Humans need to embrace fully Artificial Intelligence, the importance and various applications of Artificial Intelligence, How Artificial Intelligence is better than all inventions before it, the role of Artificial Intelligence in fighting the COVID 19 pandemic, the need for Ethical Artificial Intelligence. This study identifies where humans have gotten to in terms of narrow or strong Artificial Intelligence. Having carried out inquiries on the fears of humans accepting the full possibilities of Artificial Intelligence, this study answers two important questions firstly, will Artificial Intelligence bring about the end of the human race? Secondly, the loss of human resources in the labour market as a result of more smarter, efficient Artificial Intelligence. It is hoped this study will inform humans on why Artificial Intelligence is the single most important tool humanity has conceived.

Divergence controlled ultrasonic transmitter array for a 3-dimensional long range imaging system in air

Sahdev Kumar

Ultrasonic sensing techniques are widely used in the various scientific ultrasonic instruments using sophisticated software for various non-destructive industrial and medical applications, owing to its propagation in all kinds of medium including solids, liquids and gases except vacuum. There are many applications using ultrasonic sound in air, such as distance measurement and range imaging etc. at low cost. However, the main disadvantage is its short measurable range due to the large absorption of the ultrasonic sound in air. Another disadvantage is its bigger size. It consists of an array receiver and due to the large inter- element spacing, grating lobes appears that creates ghost images of the object. Therefore, it was the main difficulty to make it a practical product. However, because of a recent progress of Micro Electro Mechanical Systems (MEMS) technologies, it became possible to make a very small microphone array with many elements in a very small area. To extend the measurable range, some approaches were reported such as; high power sound source using spark discharge, using large scale transmitter elements and improving the signal to noise ratio (SNR) through pulse compression technique etc. In this paper, I have proposed a usage of high power ultrasonic phased array transmitter and ultrasonic array receiver using MEMS microphones for a long- range ultrasonic imaging system. The characteristics of the transmitter on the number of elements, modulated pulse width, etc. are investigated theoretically as well as experimentally. An ultrasonic array transmitter consisting of 144 (12 × 12) elements is constructed. It is controlled by four FPGAs and approximately

30 dB higher sound pressure level has been obtained than that of the single transmitter. The positions of the object are measured by delay-and-sum operations on the reflected received signal. The performance of the imaging system is compared with the system using a single transmitter. The improved 3D measurement field of an object by controlling the divergence of the ultrasonic transmitting array to improve the view angle of the system is shown. In isotropic divergence controlled system, the applied divergence is equal in both; x and y planes. In some applications a wide horizontal and narrow vertical measuring field is required. Therefore, I proposed an anisotropic divergence control system in which horizontal and the vertical divergence angles can be controlled independently. I described the principle of the anisotropic divergence control of the PAT and confirm it by numerical simulations. The anisotropic divergence of the transmitter was successfully controlled. Although, the sound pressure when the divergence was controlled 20o × 5o was about 6 dB lower than that of the PAT in phase and, 10 dB higher than the isotropic divergence controlled system and 26 dB higher than the single transmitter. The measurable range of the system with anisotropic divergence control has been improved over the isotropic divergence control by >2 m. The developed system can accurately detect the object while locating it at different positions. The maximum measurable range is > 25 m without any divergence. The developed system is useful in natural interferences e.g., smoke, fog, darkness etc. to make it a unique and novel ultrasonic long range imaging and the measurement system.

Development of the laser-induced water bubble actuator

Shigeru Omori

Aiming to realize the newly actuator without any electric cable, the use of laser-induced water vaper bubble has been proposed and performed the principle confirmation experiment. The laser induced water bubble has been applied for the liquid jet therapeutic catheter in medical field. The liquid jet system use physiologic saline for the liquid and a Ho: YAG laser of 2.1μm wavelength that has highly absorption of water. Instead of this combination, we propose the use of carbon powder suspension for working liquid and an infrared Laser Diode (LD) of 970nm wavelength. As the 970nm LD light is not absorbed by water but carbon, the water of the working liquid could be vaporized by heated carbon. LD is considered as a suitable laser source for the actuator in the viewpoint of output controllability by the drive-current modulation. Figure 1 shows the conceptual image of the laser-induced water bubble actuator. It is constructed with a 970nm LD, an optical fiber and an actuator unit with working liquid for producing bubble. An optical fiber connector (SMA connector) has been used for the bubble generator unit in our principle confirmation experiment. We use the inlet space for inserting and fixing fiber cable as the actuator cylinder. The working liquid was prepared by suspending carbon powder of 20μm particle size in water with surface active agent. After the working liquid has been injected in the cylinder, a stainless steel rod of Φ2.3mm diameter and 30mm length inserted as the actuator piston. When the laser irradiation was performed at the LD power of 160-180W and the pulse duration of 2msec, the reciprocating motions of the stainless steel rod have been observed. For the next step, we are planning to evaluate the operating characteristic and also try to maximize the generating force. This work was supported by JSPS KAKENHI Grant Number JP16K12914.

High power terahertz radiation emitter and terahertz imaging technology

Brahm Pal Singh

 Terahertz (THz) radiations lie in electromagnetic spectrum gap between the infra-red and the microwave frequencies from 0.10 THz to 30 THz. In last few decades, generation and detection of THz radiations has attracted considerable interest not only in technological applications for THz imaging but also as a tool to investigate fundamental properties of materials by using time domain THz spectroscopy. Other applications too include information technology, biomedical sciences, non-destructive evaluation, security, quality control of foods beverage and medicines, environment monitoring and ultrafast computing etc. Much effort has been made to increase the generated terahertz radiation power. Among various methods, generation of THz radiation with the biased photoconductive switch (PCS), play very important role owing to its simple configuration and power controllability by bias and geometrical scaling. The low temperature (LT) grown GaAs PCS is most commonly used due to its sub picosecond lifetime and high mobility. Though, the THz generation efficiency is limited by its low breakdown field of about 5 x 105 V/cm. Thus, wide band gap materials with high breakdown electric fields are attractive for high power THz radiation, e.g., GaN with breakdown voltage 3.3 x 106 V/cm having high saturation velocity 2.5 x 107 V/cm and high thermal conductivity 1.3 W/cm K. Thus we investigate the most straight forward electromagnetic radiation from a GaN based large aperture LA-PCS. A carbon doped epitaxial layer was used for active region to realize high resistivity to stand high bias voltage. THz pulses of 93.3 pJ/pulse energy was estimated at 500 V bias on excitation with 120 fs laser pulses of 266 nm wavelength with device structure as shown in fig.1. Figure 2 depicts the experimental setup with typical THz pulses and THz spectrum generated by LA GaN-PCS and measured with TDS detection.
