Purchase intention is defined as the level where consumers have a positive attitude towards a brand and have a commitment and tend to continue to buy products with certain brands in the future. The method used in this research is to use quantitative methods. Based on the results of research and discussion on this research are Youtube advertisements on customers of Gojek and Grab transportation in Bandung city is in the good category. Youtube advertisements and purchase intention has a low level of correlation and a coefficient of determination but it is estimated that per unit increase in youtube advertisements variable, it will increase in the purchase intention variable based on regression model.

Game of cricket is improving day by day. Development of the sport technologies is one of the major reasons behind this improvement. Hawk Eye is one such technology which is been used in the game of cricket. Due to numerous amount of assistance given by this technology for the improvement of the quality of the game it has become very popular among the public. But due to a lees number of researches carried out on this topic the public understanding regarding the technology is very much law. Therefore this paper aims to discuss the principal behind the Hawk Eye, multiple uses of it in the game of cricket, accuracy of the system, reliability of the system while suggesting future enhancements to be done.

Several Global positioning system (GPS) values were shown on Google map and Kakao map in Korean field. Global positioning system (GPS) was well used in Republic of Korea (Wikipedia, February 12, 2021). Kakao (https://en.wikipedia.org/wiki/Kakao, February 12, 2021.) map system was developed in Republic of Korea, and Google (https://en.wikipedia.org/wiki/Google, 12 February 2021) map system was in United States of America. And both of them were well utilized in geological studies in Republic of Korea. The present researchers measured Global positioning system (GPS) values on the spots near 7-8 Kyotchon-dong Yuseong-gu Daejeon in Republic of Korea. They used a cell phone of Android series, took global positioning system (GPS) values. In order to know the result, the present researchers tried to compare the shape of the curve, and the researchers found the similar cone on both the map systems. Figure 1 and Figure 2 show that these two map systems have similar position.

A number of latest technologies are being integrated by means of the telecommunications enterprise because it prepares for the subsequent technology cellular offerings. One of the key changes integrated within the multiple channel get entry to strategies is the choice of Orthogonal Frequency Division Multiple Access (OFDMA) for the air interface. This paper affords a survey of various a couple of channel get right of entry to schemes for 4G networks and explains the significance of these schemes for the development of spectral efficiencies of cognitive radio network. The paper also discusses approximately using a Multiple Input and Multiple Output (MIMO) strategies to improve sign reception and to combat the results of multi-path fading. A comparative overall performance analysis of different multiple access schemes inclusive of Time division multiple access (TDMA), FDMA, Code division multiple access (CDMA) & Orthogonal frequency division multiple access (OFDMA) is made vis-à-vis layout parameters to focus on the advantage and limitations of these schemes.

The quantity of cellular customers are increasing rather all over the world. It's far necessary to growth the channel bandwidth and capacity and on the identical time minimize the channel interference. Smart antennas are considered as an effective counter measure to achieve these necessities because they provide extensive bandwidth, less electromagnetic interference, flexibility, less weight, excessive velocity, phase control unbiased of frequency and coffee propagation loss. Smart antennas integrate the antenna array with sign processing to optimize mechanically the beam pattern in reaction to the acquired signal. Beam forming may be used for both radio or sound waves; it has determined numerous programs in radar, sonar, seismology, wireless communications, radio astronomy, speech and bio-medicine. This paper discuss the algorithm for blind and non blind adaptive beam forming technique for reliable wireless communication.

The National Seismic Code of Armenia was in force since 1994. It contained some provisions regarding the seismic isolation of buildings. However, they were not sufficiently detailed, and this caused barriers for further development of seismic isolation systems in Armenia. Elaboration of a separate chapter dedicated to the seismic isolation of buildings was needed. It was only in 2004 that the works on revision and preparation of the new edition of the National Seismic Code started. This became a good opportunity for addressing the issue again. Moreover, the extensive implementation of seismic isolation technologies especially by the private companies provided a good basis for the inclusion of a separate chapter on seismic isolation of buildings in the mentioned new edition of the Code. The proposal was finally accepted by the RA Ministry of Urban Development and for the first time in the history of development of Seismic Codes in Armenia a Chapter 10 “Seismic isolation of buildings and structures” was included in the Armenian National Seismic Code RABC II-6.02-2006 [1] and was adopted by the Government of Armenia in 2006. The main provisions of this Chapter 10, which consisted of five parts, were described by the author earlier in [2]. Later, when the “Map of Seismic Zonation of the RA Territory” was revised, there was a need to also revise the mentioned Code in force including the Chapter 10. This work started in 2019. The author of this paper is the co-author of the revised Code as a whole. However, together with participating in writing of several parts of the Code he, particularly, prepared the latest edition of the Chapter X named “Buildings and Structures with Base isolation Systems”. The works on the revised Code were accomplished in 2020.

One of the problems in Indonesia is cleanliness and waste management. Waste that is not correctly treated will lead to ozone pollution and become one of the factors causing climate change. This study aims at designing a system for the management of village cleanliness. This research uses qualitative methods of discovery and action study performed in Banyuwangi. Data collection is done through interviews and in-depth observation. Data analysis is done in order to produce system specifications to be created. The Eco Green Rural design, a village hygiene control device, is the outcome of this research. The contribution of this research is to allow the community to forecast the effects of climate change in terms of waste management and village cleanliness control and to encourage Smart Kampung and village movements based on technology for the government.
